Summary:

“The students of 3-A dorm do formally have permission to utilize the second living room for team bonding on the night of Friday, 22nd of August, and to be excused from the night check-in so long as a representative of the class texts a confirmation of accountability to the teacher on duty between 12 and 1am. Signed, the 18+ Hero: Midnight. P.s. Have fun kiddos! And Happy Birthday!”

Or: It’s Tenya’s birthday.

It’s Tenya’s birthday.

He’s sitting in the larger of the two living rooms finishing up his last bit of homework. His entire family has texted him. They have plans to go out this weekend. It’s Friday night and already the buzz of anticipation for tomorrow is a little distracting.

All of his classmates had wished him a happy birthday. No one has given him a gift, really, but that’s not something he had expected. Certainly not on a student’s budget in the middle of the week! He’s very careful with his expectations.

That said, he’s quite surprised when Ochako walks up to him just as he’s putting his pen down. She’s smiling, and he looks up to immediately thank her for her good timing; she had likely waited until he finished his work, which warms him inside. He’s very lucky to have such good friends.

“Yes, Uraraka-kun?” His ears redden a little at the diminutive they’d agreed on for when they’re in public. She’s holding out a stack of papers. He rather belatedly notices that the room had filled up over the last hour.

His girlfriend is here– obviously—and her girlfriend, Tsuyu-chan, and his two boyfriends, and Ochako’s kind-of girlfriend Mina, and her four datemates, as well as Tokoyami and Shoji, and Hagakure and Ojiro, and Shinsou.

He is very briefly happy that he gets to see everyone tonight, and even more briefly confused about where Jirou and Yaomomo were, before remembering that tonight was their date night, and Satou and Aoyoma were of course visiting their parents for the long weekend, and Koda had gone to bed early tonight…

He shakes himself out of it, realizing he’s being terribly rude, and reaches out to take the documents she’s offering him. He can’t remember any sort of class or class representative paperwork this might be, but he thumbs through them anyway with a soft smile.

Then his eyes catch on the words themselves and he has to fight not to throw the entire stack in a most undignified manner.

“O-Ochako!” he stammers, red faced and frozen. She giggles a little, which is quite a nice sound, that he would surely appreciate much more in literally any other circumstance.

He looks behind her, at his boyfriends, and they don’t look surprised. Izuku waves a little shyly.

“Did all of you know about this?” he finds himself asking, scandalized, but of course—of course they must have.

Each of the papers—the forms —begins with a typed paragraph.

I, _______________, being of sound mind and body do enthusiastically confirm my clear, informed consent to participate in one group-sex activity centered around Iida Tenya on the day of Friday, August 22, with my fellow classmates, and do further understand that this document is not a binding agreement, and I may change my mind at any time, and do further agree to use the Stoplight safeword system. I have discussed my kinks and squicks in advance and have diligently read the list of ‘final squicks’ given to me, and agree not to bring up or begin those practices during the party.

He is holding fourteen forms, all signed by the people here.

Ochako reaches over with a softer smile and tugs out the bottom form– blank—and.

Puts it on top.

“We’d never presume that you’d be willing, or that now is a good time for you, so if you don’t want to participate, don’t worry! We can change this to a later date or postpone it indefinitely if you’d prefer.”

He looks down at the empty space awaiting his name with a tight throat, overcome by emotion.

“Oh, man, you made him cry!” Kirishima hisses, sounding touched but also a bit concerned. In the background, Shouto murmurs something reassuring; his boyfriend can tell it’s the good kind of tears, most likely.

Ochako pats his shoulder.

Izuku winds his way forward and touches Tenya’s hair, soft. “It’s completely okay if you don’t want to. Absolutely no pressure.” He promises, with that—that voice of his! And the quiet conviction of a hero that Tenya would quite frankly follow through a burning building. He has, before.

“I’m—I’m good.” He manages, adjusting his glasses. He’s not quite able to make eye contact but he can see Izuku’s smile out of the corner of his eye, even as the other curls scarred hands over Iida’s softer ones.

“I—I’d quite enjoy this. Thank you.” He manages, through the emotions trapped in his throat. He swallows heavily and they all wait, very patient, as he signs his name.

Then he takes the stack and settles it neatly under his homework, which he places in his English folder, and settles into his backpack. He knows better than to leave it untended on a table so close to the couch.

Bakugou walks into the room—Tenya had not noticed his quiet exit—with a serving tray full of labeled water bottles.

“Where will we…?” Tenya asks quietly, wondering how far in advance they’d prepared, and Ochako covers Izuku’s hands over Tenya’s, reassuring.

“Oh, actually!” She lets go to rummage in her own cute little backpack. She pulls out several tubes of lubrication and even more boxes of variously-sized condoms, setting them aside almost casually—Tenya wants to blush but he also is so proud of their responsibility, and there’s nothing embarrassing about safe sex, not really, no matter how embarrassed he sometimes gets— until she emerges with a folded sheet of pink paper.

She brandishes it with triumph, before reading aloud.

“The students of 3-A dorm do formally have permission to utilize the second living room for team bonding on the night of Friday, 22nd of August, and to be excused from the night check in so long as a representative of the class texts a confirmation of accountability to the teacher on duty between 12 and 1am. Signed, the 18+ Hero: Midnight. P.s. Have fun kiddos! And Happy Birthday!”

A choked sob makes its way from his mouth and he brings both hands up abruptly to cover his face.

“Oh no!” Izuku and Ochako fret. She drops the note to touch his wrists. “Is this an embarrassment thing, because she babysat you when you were little?”

Izuku rubs his back comfortingly—no, it’s Shouto, who had wandered over while his eyes were closed.

“You got teacher permission!” He tries to say it quietly but it comes out as almost a wail, and he removes his hands to breathe and assure them that it’s happy crying.

“Oh, man, this is so manly.” Kirishima hisses to Kaminari, who—when Tenya looks over—appears to be smiling a megawatt grin.

“You deserve a good time, Class Prez.” Sero shoots over double finger guns and the idea that they would soon be participating in—nay, providing —him with that ‘good time’ made Tenya’s cheeks flare red.

“Did he say yes or not?” Bakugou asks gruffly, setting his burden down on an empty table well within everyone’s reach.

“He said yes,” Izuku murmurs in answer, and yes—that is his big hand in Tenya’s hair, smoothing it down softly.

“Good.” Bakugou huffs, and then he’s gently elbowing people out of the way until he can kneel, right at Tenya’s feet, and his hot hands are on Tenya’s knees, edging them apart.

“You understand the fuckin’ colors?” He asks, more of a demand as his red eyes bore up.

Tenya nods, well familiar.

“Say ‘em for me.” The blonde orders, and oh, my.

Tenya has to cough a little, shifting in his seat.

“Green is for good.” He manages, blinking swiftly. “Yellow for a break, or an unsure. Red is for a hard stop.”

“Great.” Bakugou says shortly. “Use ‘em if you want me to stop,” and then he pointedly brings Tenya’s hand to his hair by the wrist, like a threat, lets go—

And drops his head to mouth wetly at the front of Iida’s basketball shorts.

The fabric is really very porous and—

“Oh, oh!” He gasps, tugging gently at the blonde hair in front of him. Bakugou’s heavy tongue curls wet and pointed around his half-hard erection, laving it, even as his mouth wets the material.

“This is—really very—” Nice, he wants to say, but it’s actually a little mean, and Tenya’s toes curls at the unexpected pleasure of it.

Shouto’s hands go from rubbing his back to sliding over his shoulders; at some point he’d maneuvered to stand behind the couch, or maybe he’d started there. His firm stomach is behind Tenya’s head and his arms drape over Tenya’s broad shoulders, reaching down with his mismatched hands to stroke down neck muscles and collar bones and massage Tenya’s pecs.

“I’d like to try some temperature play.” Shouto says, quietly. Tenya can hear the smile in his voice. “Would you like that? ‘No’ is fine, too. We have a lot of options.”

Tenya sucks in a gasp, cock twitching against Bakugou’s lips.

“That. That sounds fine.” He manages, trying not to pull too hard at the hair around his fingers.

The hands on his chest get hotter and colder respectively and Tenya squirms. He can feel Shouto looking down at him curiously, feel the way he explores—and plays —with the edge of Tenya’s pecs, the dip between, with his nipples and the sensitive skin around them.

“Wow, that’s hot.” Ochako mumbles, and Izuku laughs a little.

“You can’t even see the difference,” Someone—Kaminari—points out, “Also: quirk kink, fuck yeah.”

“It’s still hot,” Sero says, reasonably. Tenya looks over and finds both of them petting Bakugou. “Like, look at the way Iida shivers for it.”

Tenya flushes hot.

Kirishima shimmies in out of nowhere—their little corner of the room is rapidly increasing in temperature—and slides his hand down Bakugou’s cargo shorts, gripping him visibly. It’s alarmingly lewd, the outline of his hand through the fabric, and Bakugou pants against Tenya’s own tent.

That makes four out of five, so where—Ah, there.

Tenya convinces his eyes to focus and sees Ashido walking over, already down to her shirt and underwear, the former of which she is slowly unbuttoning. Her legs are long and pink and Tenya forces his eyes up to her face, some level of ashamed, but that’s—incredibly—not much better.

She’s smiling, a somehow dirty expression, as if she knows exactly what he’s thinking and is thinking worse.

He pants, leaning into Ochako’s hand. When had she cupped his cheek?

She leans in for a kiss and Tenya sighs into it, grateful.

Mina says: “Tsu, hun, would you eat me out? I wanna give Class Prez his first ride of the night and your tongue is divine.”

“Sure,” Tsuyu agrees, and Tenya feels the couch cushions to his left shift. “I would love to. It makes me happy, getting you ready—getting you hot and bothered.”

Tenya is not the only one to groan; he pulls away from Ochako’s mouth with an aborted cry, curling around Bakugou’s head; Bakugou himself had moaned open and unashamed against Tenya’s cock, the vibrations travelling right into the heart of him.

“She sure is Best Mouth for your crew,” Sero admits, sounding dazed. He presses his sweaty forehead into Tenya’s large thigh, having knelt down next to them at some point. When Tenya looks over, curious, he finds Kaminari’s hand disappearing behind him, Sero’s hips spasming every few seconds to a rhythm Iida knows well.

He flushes, looking away, but of course everyone around them is engaged by now in similar acts and he’s allowed to look. Encouraged, even. Kaminari catches his eye and winks.

Shouto’s fingers pinch his nipples at the same time, too hot and too cold, and Tenya throws his head back, overwhelmed by the sensation.

To his left, Mina cries out through a particularly gripping orgasm, riding Tsu’s face, and Tsu groans appreciatively as Ochako presses a kiss to her calf, thrown up over her shoulder.

Ochako is sitting right next to Tenya, both of Tsu’s legs over her shoulders, and is grinding against her like she wishes she’d brought a strap-on along. Tenya isn’t the only one to stop and watch, rivetted, as Mina rides out another toe-curling orgasm.

“Okay, okay, enough for now,” She taps Tsu’s shoulder and the dark-haired girl reluctantly lets her climb off, shaky legged and glistening. Tsu reaches out and Ochako falls down easily, pressing them chest to chest, so that they can grind a little against each other. Tenya watches Ochako’s hand sneak down between them just before his vision is obscured by soft pink like a sunrise and—

Oh, dear, yes.

Mina had a plan. How had he forgotten? He fumbled with his glasses, slipping down the sweaty bridge of his nose—he’s still fully dressed —and Shouto leans upside-down to kiss him softly before pulling away to make room.

Bakugou sucks roughly at him, not to be forgotten, and Tenya ruts up against his mouth a little before the blonde whines, reluctant, but gamely pulls off entirely.

“Hey, Mina.” He says, voice rough and chin wet. “Got him all hard for you.”

“Thanks, love!” She leaned down to kiss him, surprisingly soft. His chin was tilted high into it, face lifted, and for a moment she looked entirely like Aphrodite bestowing the gift of her affection. Tenya has to blink hard, then take several steadying breaths as he notices Bakugou’s mouth is wet, and hears the little surprised sound he makes when Mina chases the taste–

One of Shouto’s hands rests on the back of his neck.

The kiss in front of him breaks softly, Mina pulling away and Bakugou looking as dazed as Tenya feels, pupils blown wide, jaw slack. She turns to him.

“Ease up for me, Emergency Exit?” Tenya finds himself lifting his hips as Ashido—assisted one-handed by Bakugou—pulls his shorts and then his boxers off.

Izuku darts, quirk-fast, to the table and comes back at a much more reasonable speed, rubbing his hair in embarrassment; it appears as if he’s flicking off the remaining little bolts of green lightning.

“Sorry, excited.” He breathes, carefully pulling open the wrapper and lowering it on with an endearing look of concentration. He looks rapt.

Tenya forces himself to take a deep breath, but all too soon Izuku’s hands are moving away, Ashido’s hands are settling on his shoulders, and then she’s maneuvering into his lap.

“Birthday sex!” She grins, and then something sly comes over her—as Kaminari laughs in the background—and she leans in to nose at his neck.

She reaches up with one hand and catches Shouto’s, bringing it close, just so she can tease with teeth and kisses at his fingertips.

He laughs softly behind Tenya.

“Is this position okay, Iida-kun?” She asks, slipping that much closer. Her bare chest brushes against his shirt. It’s entirely inappropriate—or. Appropriate, for this situation? Tenya’s head spins.

“It’s fine.” He manages.

“Just fine? Only fine?” She leans forward, pressing her cleavage up tight between them. “That’s not a ‘yes’.”

Oh, that was almost cruel.

“I like this position.” He tells her, trying to smile. He’s a touch too breathless for it. “This position is good for me.”

“Good.” Mina says, decisively, then rises up—only to pause. “Can I get you in me?” She asks, hovering right on the edge of sinking down.

Tenya groans, his hands moving to her hips.

“Please.” He invites, the word punched out of him. He sucks in air only to choke a little as she, bearing her weight on his shoulders, lowers herself right down onto him, tight and warm. No hesitation. Iida struggles to keep his hips still and his breathing under control.

“Damn, ain’t she pretty?” Sero asks, hushed, and Tenya looks over to see his cheek pressed into Tenya’s outer thigh and his eyes dreamy as Kaminari fingeres him.

It was lucky Tenya’s lap was so accommodating, and that Ashido didn’t take up too much room. Sero kissed her thigh.

“Don’t stop, babe.” He said to Kaminari, who groaned into Sero’s neck.

Bakugou looked at both of them with bedroom eyes.

Izuku looked at all of them, biting his lip, frame a touch tense. Like he wanted something but wasn’t sure how to ask for it.

Bakugou looked at Tenya’s face, struggling to adjust to Ashido’s complete envelopment, and followed his gaze to Izuku, eyes narrowing.

“For fuck’s sake.” He muttered, leaning forward to grab Izuku by the back of the neck and pull him in. He stopped at the last second, darting a look to the couch, and then dipped his eyes.

“Can I kiss you?” He breathed. Izuku’s eyes fluttered half shut, a heavy swallow.

“Oh, god.” He said. “This was a terrible mistake.”

“Hey, fuck you, consent is sexy.” Shinsou called from the other side of the room.

“Dude,” Kaminari and Sero echoed, probably at the irony, but Bakugou rolled his eyes and kissed Izuku anyway.

Tenya vastly appreciated the effort. He could hardly believe they were, all of them, indulging his kink like this, right here in the living room.

“You didn’t have to do all this for me,” He said quietly, warmed at the thought. Consent was, of course, necessary, and Tenya was prepared to—how did it go?—fistfight in the back of a Denny’s parking lot at 3am over it, but it was also sexy. Very, very sexy, to have someone confirm that they want you, to have all that enthusiasm pressed up against you—

“Can I move?” Ashido asked, breathy, and Tenya shuddered.

“Yes, please.” He swallowed. “Can I hold onto your hips?”

He was already holding onto her hips, but her hands fell from his shoulders to cover his—much bigger—hands and she used that leverage to rise up and fall back down on him, riding him, and behind him Shouto moaned softly.

Tenya disentangled one hand—Ashido made a little noise of complaint that shifted midway to approval when he grabbed for one of Shouto’s, above his head, and Shouto held onto Tenya’s hand eagerly, a little too tight, and it occurred to him that Shouto was absolutely getting—all hot and bothered back there.

“Oh, yeah, gotta get in on that.” Shinsou said, and Tenya could just look over and make out his frame disentangling from either Shoji and Tokoyami—likely—or perhaps the just as possible coupling of Hagakure and Ojiro—Hagakure’s presence did make it hard to figure out who was doing what, over there—and jogged over, struggling to keep his pants up, unbuttoned as they were.

He got to behind the couch and Tenya heard the definite sound of his pants hitting the floor. Ashido clenched tight around him, a perfect warmth, and he lost the plot for a few seconds. Then he looked back and over to see Shinsou’s big hands frame Shouto’s face and lean in, almost too quiet to hear.

“Wanna get off with me, Todoroki?”

And Shouto laughed, soft and amused, and then they were kissing so presumably he had nodded, or Shinsou ascertained somehow from his expression that he was amenable, but Iida was pulled into a wet kiss with Mina and didn’t get to see, though (to be clear) he wasn’t complaining.

Shouto didn’t let go of his hand and Tenya gripped it a little tighter in encouragement.

“Ah, Ocha-hun!” Tsu arched under Ochako’s clever fingers, the kind of thing he just wasn’t used to Sseeing all that often, no matter how long they’d been dating—Tsu didn’t tag along to many threesomes, for obvious reasons—and afterwards Tsu begged off to take a break, get some water, and possibly wander over to tempt Hagakure into something.

Tenya couldn’t pay attention, not even to make sure everyone stayed hydrated.

“Oh, oh—you should—” Ashido lifted her free hand to tangle in Tenya’s hair, tugging until he leaned forward and suddenly his face was between her breasts and he could admit to some surprise, but also, took it as a request and let go of her hip and Shouto’s hand to cup them on either side of his face, to rub a big thumb over the sensitive outer edges at the line of her pectorals, to press them close around him—

“Go, Ten!” Ochako called weakly from the couch, collapsed onto the cushions. She was probably offering him a thumbs up but of course he couldn’t see it.

“Move over, round cheeks,” Bakugou called out, voice not as loud as it could be—he was out of breath from kissing, and Tenya mourned a bit that he’d missed that show; those two rarely indulged in front of an audience—

“Ask nicely.” Ochako asserted, one of her feet settling on the edge of his cushion as she presumably lounged out. Tenya couldn’t have been the only one who shivered a little.

“Can you please make some room for me, angel?”

Izuku made a strangled noise from nearby.

Tenya laved a gently sucking kiss to Ashido’s areola, and she tipped her head back to breathless laughter.

“Y’all were not prepared for Katsuki to bring out the big guns,” She said, to which Sero and Kaminari echoed, “Y’all.”

She swatted at them halfheartedly, not quite reaching.

Kirishima’s “y’all” echoed somehow from the other side of the room, half a beat late, and Tenya looked back to see him in Ojiro’s lap. Hagakure was nowhere to be seen—naturally—but since neither was Kirishima’s penis Tenya could make an educated guess as to what was going on. Tsuyu was kneeling in that direction as well, both hands touching the open air—

Tenya looked away with a sharp breath, realizing she was doing what he was doing, or rather failing to do, as Ashido’s chest lifted pointedly up into his faltering palms.

“Yeah, okay.” Ochako agreed, as though she wasn’t flustered by the request.

“Thank you,” Bakugou said, plain but not sarcastic, and Tenya’s heart was beating fast. He reached a hand between them to stroke Ashido’s clit anyway, which very quickly took up his attention as she shivered and squealed in his arms.

“Don’t—don’t ever say Class Prez left a girl hangin’!” She giggled, and Tenya was tempted to direct his hands to her bottom instead—very round, very beguiling, but it didn’t seem like the thing he should—

Ashido leaned forward to rub her whole front against him as she rode his cock slow and Tenya groaned, hips jerking erratically.

“May I—touch you—”

“Anywhere,” Ashido gasped, and Tenya gripped her by the cheeks to lend his rather impressive forearm strength to the endeavor, quickening their pace until he spilled abruptly into the condom.

“Oh, wow.” Ashido tittered, a hand flat on his pec as she caught her breath. “What a ride. Ten out of ten—hey, Ten, get it? For Tenya!?– would recommend.”

She did a double thumbs-up and enunciated, “Yayyyyy~”

“Dick!” Kaminari shouted from below, but as he was buried rather deep in Sero he didn’t sound too bothered, laughing.

Ashido got off of his lap and Tenya carefully removed the condom, tying it and dropping it into a nearby wastebasket.

He could hear the wet, messy sounds of Shinsou and Shouto kissing against the back of the couch, very close to him, and now he could carefully get up and kneel on it, facing them, enough to see —

Shouto was half-sitting on the back of it, legs wrapped around Shinsou’s waist, and they were grinding against each other.

Tenya leaned forward and pressed a kiss to Shouto’s arm, his shoulder, the side of his neck, and Shinsou stopped the kiss to lean over—only to pause, an inch away from his upturned face.

“You good to kiss me?” He asked, and—warmed– Tenya leaned forward to do so, answering without an answer.

But, oh!—Shinsou frowned reflexively and Tenya realized his mistake, hastily correcting himself.

“Yes—wait, yes, please, I’m good to kiss you. Ask me again. I’m trying to work on my non-verbal cues instead of relying on—”

Shinsou’s expression softened—a direct contrast to Shouto’s screwing up in pleasure right next to them—and he kissed the tip of Tenya’s nose.

“Don’t worry about it, Class Prez.” He drawled lazily. “Force of habit.”

“Ask me another question.” Tenya insisted.

“Alright. You gonna let those three get it on without you?” He nudged his head over to the other side of the couch, to where Ochako, Izuku and Bakugou were deciding their arrangement one pet, stroke and kiss at a time.

“No, not at all. I’ll join them presently.” Tenya smiled and kissed Shinsou again, soft and lingering, and was rewarded with a smile under his lips.

“Go,” Shinsou ordered, and Tenya pecked him once more before complying.

Seeing Tenya’s renewed attention, Bakugou glanced over and smirked.

“Hey, Izuku —” Izuku sucked in air harshly. “Can I touch you? Can I kiss you until you come for me, all pretty?”

“Hrk.” Someone said. Tenya. Tenya said that. Ochako looked at them with wide eyes.

“Katsuki,” Izuku breathed out, batting his lashes. “Can I fuck you?”

Bakugou’s eyes grew wide, breath short. A brief silence echoed.

“Jesus fuck. Dude,” Kaminari laughed. “Did you give all of us that kink?”

Bakugou shook himself, snorted.

“We can use each other’s names.” He protested, defensive.

“Yeah but you really don’t.” Sero pointed out. Izuku buried his face in Bakugou’s tit. “Like, at all. Why was that so hot?”

“I don’t fuckin’ know, why do you think weird things are hot?”

“Babe,” Sero laughed. “I think everything you do is hot.”

“Well I thought that was particularly hot,” Ochako said, firm. “Whew.” She fanned herself.

“So I can’t help but notice the birthday boy isn’t getting any love.” Sero noted, “and—fuck, baby, points for not stopping for nothing’.”

Kaminari had continued to rock his hips into his datemate, tan dainty hands so sure on his hips, and Tenya was certainly not un affected by their close proximity, kneeling as they were just to his right.

“That. Isn’t that uncomfortable?” He managed, wetting his lips, and they both looked at him with rather dreamy expressions, perspiring.

“Hmm, I dunno. Bro? You feeling uncomfortable?” Kaminari made a slow, dragging thrust that had Sero scrambling against the couch and Tenya’s knee, against which he was almost pressed. Sero dissolved into breathless cursing.

He used one knee to nudge Sero’s open further, deepening the angle, and Tenya heard the scrape of Sero’s jeans on the carpet to which they had fallen at the start of this, cushioning and hindering all in one.

Sero’s face blossomed red and he bit his own lip, glancing at Tenya’s face and away again.

“You don’t know how weird it is to see him like this.” Bakugou grinned, also to Tenya’s right but up on the couch. “Usually he’d be smirking and eyein’ you up.”

“Katsuki,” Sero hissed, strangled.

Kaminari laughed, not unkindly.

“You wanna give the birthday boy a present, Hanta?” He nuzzled Sero’s black hair from behind.

Sero groaned.

“You know if you could text like that—”

“We’re not here to disparage my dirty talk, Hanta.” Kaminari’s voice rose several octaves. He got his breath back and adopted a positively roguish grin. Tenya caught himself thinking that the two had rather swapped dispositions, for the evening, and that more than anything told him how truly affected the black-haired datemate was.

To the right, Izuku and Ochako and Bakugou arrange their limbs a little, threatening to steal Tenya’s attention. He manfully resists and is rewarded by explanation of what made Kaminari smirk like that.

“Here, bro, I’ve got an idea.” His voice was wicked; Sero tried to cover his red face with his hands.

“Babe you’ve been edging me for this long, I don’t think I can take any ‘ideas’.” He spoke through his fingers.

“Mm, nope, you can take it.” Kaminari moved his own knees, almost walking Sero over a few inches, and his datemate had no choice but to follow, hands kind of feeding his balance as they shuffled over, and then Sero looked up and made a high-noise in the back of his throat.

“Hello.” Tenya tried a smile and wasn’t sure where it landed. One of his hands fell into silky black hair. Sero was face-to-‘face’ with Tenya’s half-erect penis and Tenya watched him gulp, bite his lip, and ultimately the way his eyes were swallowed by dark pupil.

He couldn’t help but notice the way his hand was big enough to almost cover the back of Sero’s skull.

“He likes that you’re not hard.” Bakugou confided, to Sero’s betrayed whine. “He likes that you’re gonna be a little soft in his mouth, that he can feel you grow. Likes that you’ve already gone once so it might take a second.”

Sero buried his face in Tenya’s inner thigh. Tenya pet his hair comfortingly, ignoring the way his own face was on fire.

“He likes that he gets to lick you clean.” Kaminari smiles, pulling out to—Tenya has to crane his neck, a little—rub the length of him up and down Sero’s cleft, a tease against the reddened flesh of his hole.

Sero whines again, longer and louder. Tenya can’t help but think how that sound will feel on his cock.

“He likes,” Bakugou kissed Izuku’s shoulder, mouthing freckles there. “That you taste like Mina.”

“Oh fuck.” Ochako hisses, shivering. “Noo, that has no business being so hot.”

She looks like she wants to cover her own face and Katsuki chuckles breathily, unashamed.

Sero’s breath is fanning out so fast against his thigh.

“Come on, bro.” Kaminari nudges Sero at the back of his knee. “Say ‘Happy Birthday.’”

“Say it choking on cock,” Bakugou advises, and four different people splutter. Tenya is one of them. He looks heavenward for patience, slowly twitching to full hardness as this goes on. Sero is right there.

“Best Mouth.” Kaminari mutters, grinning, leaning forward to lavish kisses against the back of Sero’s neck. Sero whines something that could be ‘unfair’ or ‘right there.’

“Oh wow, does that mean I’m getting double ‘Best Fucks’ right here?” Ochako smiles wide; Bakugou immediately scowls at the reminder. He snorts.

“Well, if I have to share my title with fucking Deku of all people, this is the best way to share the title.” His strong hands reach past Izuku to touch her waist.

Izuku groaned.

“Why are you like this?” He murmured, stroking down Bakugou’s ribs.

“Question for th’ ages.” Bakugou snorted, looking every bit the unconcerned brat. He was grinning, now, and clearly enjoying himself. His head turned toward their girlfriend.

“Well, Angel? You want us to share you?” Ochako blinked a few times, pink staining her already flushed cheeks.

“I can’t say I’ve never thought about it.” She admits. Tenya turns his head further to see Izuku’s face and isn’t disappointed.

“You should let her fuck you,” Izuku leans close to whisper in his ear. Bakugou shudders. “She’s good at that.”

“You got a piece on you, Angel?” His voice shakes a little through the bravado.

“I came prepared to party.” She allows, looking momentarily beyond them both to smile winningly at Tenya. “We made sure to have all our supplies ready and at hand.”

She winked at him.

Tenya smiled back helplessly.

“Do you got a cock or not?” Bakugou asked impatiently, and Tenya was abruptly and singularly distracted by the sudden fingers curling around his penis. He made no show of looking down, and Sero seemed to gain confidence; he went from a fluttering touch to something like a grip, however experimental.

Kaminari cooed something encouraging.

“—get it out of my bag.” Ochako was saying, when Tenya could recalibrate his ears and listen once more. Izuku was mouthing something too quiet to hear against the shell of Bakugou’s ear; whatever it was turned them both steadily pinker.

Sero picked up confidence with Tenya’s cock, settling into a steady rhythm that set a sweat to breaking at the back of Tenya’s neck; he ran his fingers encouragingly through Sero’s hair.

Ochako got up from the couch, but didn’t go far.

Izuku ran his hand down Bakugou’s chest from behind and slipped it into the front of his sweatpants, which did nothing to conceal the happenings therein. Bakugou leaned back against Deku and rocked into it.

Both of them were fully dressed, yet Tenya somehow felt this was one of the more lewd displays of the evening. Something about Bakugou’s head on Deku’s shoulder, cheeks flushed, starting to pant. At the way the outline of Deku’s knuckles shook a little.

“Is that the best you got, Izuku?”

Izuku shivered. His eyes shimmered jade.

“You talk a lot.” He offered, in that lazy drawl that sometimes came upon him. He took his free hand and brushed his thumb against Katsuki’s jaw, which fell open.

Tenya flushed with Bakugou as Izuku slipped scarred fingers over his tongue, eyes half lidded and smug, other hand still slowly pulling him off.

“Happy birthday to me,” Ochako straightened up from her backpack and then paused. “Ten, honey, do y’all need anything? Condoms?”

A bit of shuffling in his lap. Sero dipped his head to kiss Tenya’s glans, then pull away, far more shy than Tenya had previously assumed any member of the ‘Bakusquad’ could be. He swung his easy-going grin over his shoulder at her, and his voice cracked a bit as he answered.

“I think we’re good, thanks.” Those dark eyes turned back to Tenya’s face, for once, and his smile didn’t falter.

Tenya fought the urge to cover his own face.

‘He wants to taste.’ They’d said, and Sero looked a little embarrassed but not at all like he intended to contradict his lovers.

“I know we’re all clean,” Sero began, seemingly having collected his composure, because he also started stroking Tenya off casually with the words. “Aizawa makes sure of it with all the blood tests, so this fine, right?”

Tenya finds himself groaning; whether at the touch, the words, or the forbidden name dropping, he’s not sure.

“Don’t talk about our dad during sex!” Kaminari chastises, holding himself with one hand to rub his head more firmly against Sero’s cleft and lower.

“Speak for yourself,” Shinsou huffed under his breath, and Shouto muttered something into his shoulder, likely about Midoriya’s parentage.

“Oh, I didn’t notice!” Kaminari perked up, delighted. “Shinsou, you’re wearing the shirt!”

Heads turned from all across the room.

“Everybody say hey~~ ” Kaminari quoted, and the class echoed like it was some sort of Go Beyond/Plus Ultra type of requirement.

Shinsou grunted, cheeks red.

“’If you’re gay say ‘hey’,” He mused. “If you’re… in the middle of an orgy, say…” His voice trailed off. “Nope, I got nothing.”

“Oh fuck you man, that’s all I’m going to be thinking about for the next little bit. What even rhymes with orgy?” Kaminari said.

“Figure it out and get me a shirt made.” Shinsou advised. Shouto tugged him closer, quickly occupying his mouth, which Shinsou gamely indulged in.

A sound drew their attention to Bakugou; perhaps one of amusement, perhaps one of derision. It was hard to tell while he was sucking on Izuku’s fingers, lazily and shallowly thrusting in and out of his mouth.

Ochako had returned to the couch and was feeling up his substantial chest, where it was more or less on display and facing her, from the position. A small pile of condoms, lubricant, and her strap-on sat next to her.

“God he has such nice tits.” She told Izuku, or possibly the room at large. Izuku bit his lip, eyes agreeing. Bakugou rolled his eyes.

“You’re still half-hard.” Sero says, voice pitched low. “You mind if I…?”

He trails off meaningfully and Iida swallows.

“Go ahead.” He manages.

Kaminari and Tenya watch with awe as Sero braces his hands on Tenya’s large thighs, going in almost from the side so he can gather Iida gently in his mouth.

“You ever had someone suck you soft before?” Kaminari grins, reaching his free hand to nudge Iida’s knee playfully.

“It’s—different.” Tenya gasped. He started twitching in Sero’s hot mouth almost immediately, filling out as blood rushed down.

“Wanna hear a secret?” Kaminari leans a little closer, rubbing Sero’s back encouragingly. “Feel how he’s not sucking or playing with you? He loves cockwarming.”

Sero shivered around his length.

“Damn, Sparky out here putting people’s kinks on main.” Bakugou pulled off Izuku’s fingers to pant.

“Oh? You wanna talk shit?” Suddenly wary, Bakugou couldn’t do anything in time to prevent the next words. “We already know Blasty loves some praise, Midoriya. You should get on that.”

“Goddamn, Sparky, bringing your A-game to this chili’s tonight.” Bakugou cursed.

“You think it’ll work, from me?” Izuku asked, amused and curious.

“Either it really, really will.” Kaminari shrugged. “Or it really, really won’t. From you, specifically.”

“Yeah.” Izuku laughed. “That’s how it usually is, isn’t it, Kacchan?”

“You’re not fucking special.” Bakugou lies, glaring. Ochako drapes her hands over his waist and leans down to kiss and lick between his pecs. He presses up into her.

“You are.” Izuku counters, almost breathless with excitement. “You’re so fucking special, Katsuki. I’ve always admired you.”

Bakugou’s mouth gets caught mid-complaint. He stares. Izuku’s hand continues to rub him under his sweats and boxers, slow and sweet.

“Hit.” Kaminari kisses the top of Sero’s spine.

“They’re not Battleship,” Sero pulls off Tenya’s filling length to admonish, just as quiet.

“I mean they kinda are?” Kaminari counters. “If you think about it?”

“Can’t think.” Sero takes Iida in hand and licks the tip, slow and methodical. “Brain AWOL.”

“Here, sit up a bit before you go back down. Let me get your shirt off.” Sero complies. “There, out of the way.”

“You gonna get back in me, any time soon?” Sero asks like it’s an idle question. Like he doesn’t particularly care one way or another. His breath hits Tenya’s penis.

“Mm. I was thinkin’ about it.” Kaminari lines back up. “You think you can multitask like this?”

Sero snorts. “We’ve had that conversation before.”

“Heh. Yeah we have.” He slides in with a steady push and Sero groans, dropping his head eagerly back to his ‘gift’ so Tenya can feel the vibrations. More than that, he can feel the little push and pull as Kaminari thrusts in and out of him.

It’s obscene.

Tenya is more hard than not, now, but Sero doesn’t seem to mind. He seems content to hold Tenya in place, with the occasional flick of his tongue, and let Tenya more or less enjoy the various shows.

“Let me know if you get uncomfortable.” Tenya murmurs, carding Sero’s hair back from his forehead. Sero nods around him, eyes blown. Tenya clenches up on accident, hand shaking.

Kaminari sets a relatively slow pace and Tenya can feel every facet of it.

Ochako is sucking on Bakugou’s nipple, shirt pressed up under his armpits. He’s got one hand wrapped around Izuku’s neck from behind, the other cradling her head. Her hands migrate upward to massage the muscles on either side of her face, which puts Tenya in mind of something he will admit precisely never, and for a moment he wonders how the entire conflagration is upright.

Then he spots Izuku’s hand, sturdy on Bakugou’s hip, and discovers his boyfriend had elected to stop stroking him off in order to hold him in place and keep his mouth full.

Bakugou’s jaw works around the fingers that had re-entered his mouth at some point in the last few minutes. Sero makes a noise around Tenya that begs for attention; Kaminari had done something particularly delightful inside him.

Right behind Tenya’s head, Shouto is perched against the back of the couch, Shinsou pressed all up against him. He can’t hear what they’re doing, beyond kissing, and his imagination fills in all the lewd gaps, wondering what all they’re wearing or if they’ve managed to take it all off.

“If I’m going to fuck you,” Ochako started, pulling back to press the words like kisses against his heart. “What’s this for?”

She wiggles one hand down between them, petting the black of his sweats. He rocks into it, as best he can all draped over Izuku; his spare hand drops from her hair and joins its brother.

Her breath and Tenya’s both jump to see him, biceps straining, on display. Izuku nuzzles into his bare shoulder. When had Katsuki lost the shirt?

“Hopefully me,” Izuku mutters, which gets a laugh out of Ochako and Kaminari both. Bakugou groans wordless around the fingers in his mouth. A little saliva has come down his chin.

“Let’s see…” Ochako tweaked one nipple, the one she hadn’t been suckling, and used her other hand to fondle him. Bakugou turned his head just slightly into Midoriya’s neck, flushed and quite whelmed.

“I could face Tenya,” Izuku offered. “And you could face Kacchan.”

“We could spitroast him.” Ochako countered, ever the shrewd barterer, and Tenya choked on his own spit.

Sero moaned appreciatively around him. Both of Tenya’s hands dropped to clutch the sides of his head. He fought to keep his buttocks firmly on the cushion and not thrust up into the warm cavern wrapped around him.

“Mm !” Bakugou protested, whether at the suggestion or the way they were ignoring him, no one could tell. Midoriya looked at him, almost unaffected, and dipped his fingers in a little deeper.

“Something to say, Kacchan?” Pressure on his tongue, rubbing. Bakugou went a little cross-eyed. “That’s what I thought.”

“God it’s hot when you get all dom on us, Midoriya.” Kaminari gasped, now sweating as well. Sero was working back into him now, using the rhythm to bob up and down on Tenya.

“Hit me up sometime.” Deku hums, and Kaminari’s hips stutter as he curses.

“Fuck dude, I’m not sure I’d survive it!” The blonde laughs, breathless.

“I can hold you together.” Deku promises, idly now. “I’m very strong, you see.”

He slips his hand out of Katsuki’s mouth—who immediately starts cussing under his breath—to drop both hands to his prominent hip bones, dragging his clothed erection against Bakugou’s ass. Bakugou, for his part, keeps both hands wrapped backwards and above him around Deku’s neck.

“Fuck that’s good to look at.” Ochako leans in, to mouth at Katsuki’s bared neck, tendons straining. Her cute little hand works all up and down his shaft.

“Oh god.” Shinsou’s strangled voice touches all of them. His eyes are blown wide, Shouto’s face pressed firmly into his chest, as he does—something– with his hips.

Ochako is the least encumbered of all of them, but Izuku merely has to tilt his head back to glance over, and what he sees there draws a curse from his lips.

“Shinsou um. Just pushed in. To Shouto. With his dick.”

“Where’d all that suave go from a second ago, nerd?” Bakugou asks, but his voice is almost subdued. Scratchy, a little. Rough.

Ochako dropped a hand to the front of her skirt to touch herself.

They blinked at her.

“What? That’s hot. Look at them.”

Shouto still had his forehead against Shinsou’s shoulder, panting. Shinsou was still visibly affected by the slow slide in, legs trembling despite the couch taking most of Shouto’s weight.

“If I push you into the back of the couch from this side, and Ochako fucks you good, will you kiss him?” Izuku’s eyes are alight and dangerous as he bites at Bakugou’s ear. “All braced against the top, your dick rubbing into the fabric.”

Bakugou shudders.

“Which one?” He asks, as if there’s some debate to it.

“Shinsou, probably.” Ochako figures. “There’s no real way to kiss Sho like that, unless they turn around for some reason.”

“Not even then.” Deku disagrees. “And he’d have to strain up to reach Shinsou.”

“I don’t wanna kiss you fucking extras.” Bakugou lies, whining through his teeth as Ochako plays with him and Deku bites at his neck.

“He’s lying.” Sero pops off to say, voice wrecked and breathless. Tenya groans. “He loves kissing.”

“Back down, Best Mouth, before I put you down,” Bakugou growls.

Sero laughs but giddily obeys, this time lowering himself with a fervor of licks and sucks and kisses that makes Tenya’s hands tremble against his face.

“Oh, he’s putting the moves on Class Prez’.” Kaminari realizes, sounding delighted but also close to his own orgasm. “Fuck, bro, I’m not sure how long I can hold out.”

As if in answer, Sero somehow redoubles his efforts. It becomes impossible not to thrust up into the slick heat of him, to match the rhythm he’s set.

“Let me finger you open?” Izuku says, almost conversationally; hardly a question at all. Bakugou groans, all vowels, and humps up into Ochako’s touch.

“Yeah.” He bites out, like it hurts, and Izuku reaches for the tube of lube. Bakugou disengages, shaking out his arms briefly so he can use them to step out of his pants and underwear.

The first finger goes in slow. Izuku has big, scarred fingers, wider than you’d expect; Tenya can personally attest. Having Izuku work you open is an experience.

They’ve settled with Izuku’s back against the couch, just next to Tenya—and with Shouto braced between their heads, of course—and Bakugou is sitting upright facing him, legs thrown haphazardly over Izuku’s wide and freckled ones. It affords the rest of the room, and Ochako, an easy view to the pert buttocks and the hand spreading it.

On the rightmost and final cushion on this section of the couch, Ochako is sliding dark, thick straps up her strong legs, her cock dangling from the ones she hasn’t fastened yet.

She gets it in place, straps crisscrossed stark and black against her thighs, and gives herself a little stroke, eyes half-lidded. Izuku gets a second finger pressed deep into Bakugou, who shakes like something much larger is breaching him, both hands on Izuku’s shoulders for balance and stability.

“You could lean over and give Tenya a kiss, Kacchan.” Izuku suggests, like his eyes aren’t forests at midnight and want isn’t weighing down the words.

“Fine, fuck!” Bakugou leans over with aggression, stopping just shy of Tenya’s shoulders. Tenya closes the distance, sweaty and overwhelmed and close to his own orgasm, and presses an open-mouthed kiss to Bakugou’s lips that the blonde moans into instantly.

Sero reaches to cup Tenya’s balls, giving them a few gentle tugs while he lowers down all the way, and the clenching-fluttering muscles at the back of his throat send Tenya gasping over the edge. He may or may not bite down sharply on Bakugou’s lip as he does.

“Ah, fuck!” Bakugou jerks back, heaving in air, eyes wrenched tight in pleasure as Izuku corkscrews his fingers almost roughly. “Goddamnit, Deku, give me—give me a fuckin’ second, god.”

His lip is red but not bleeding. He looks wild-eyed, when Tenya’s vision stops being greyed out with pleasure and can see him. Sero swallows around him again and again and Tenya only barely manages not to pull his hair too hard.

Behind him, Kaminari spills with a startled gasp, hips spasming through it.

Sero eventually pulls off when Tenya taps out, flaccid penis wincing in discomfort.

“One day you should let me keep going.” Sero admits, grinning and rubbing at his throat. “You know, keep real still until the sensitivity passes, and then hold you soft in my mouth until you get hard again.”

“That—” Tenya clears his throat, winded. “That could take several long minutes.”

“Oh, he knows.” Kaminari slips free with a wince, eyes darting down to where his release starts to—so slowly—drip out of his datemate. Sero gasps to be empty, or at the feeling; either way his face goes from pink to red with little warning.

“It’s part of the appeal.” Sero admits breathlessly. “Actually, no one talk to me about this for a bit. You good back there, baby?”

“Oh, never better.” Kaminari says. He thumbs open Sero’s other red cheeks. Sero buries his face into Iida’s leg.

“Denks.” He laughs, sounding embarrassed.

“Mm, bro, you look so good full’a me.”

Sero makes a strangled noise.

“Where was this during the bet?” He laughs in disbelief.

“What can I say?” Kaminari rubs his thumb over the white seeping out. “I learned from the best.”

“Flattery will get you everywhere.” Sero leered.

“Flattery kinda already did, bro.” Kaminari slapped his cheek a little, watching intently between them. “It wasn’t that hard.”

“There he is.” Sero murmured, arching his ass back a little into Kaminari’s hands. “That’s the foot-in-mouth fucker I know and love.”

“So Kirishima’s daddy kink was off the table—”

“Hey!” From the other side of the room, which they both ignored,

“—but now you wanna talk about feet in my mouth?”

Sero shoves at him, sitting up from where he’s bent over Iida’s lap.

Kaminari comes down laughing.

“No, you know what? I’m not going to stand for this. Hagakure, hold my girlfriend.” Kirishima raises his voice to be heard across the room. Mina gasps something breathless and Hagakure giggles, followed by a slip of a moan that could come from anyone, and then Kirishima is joining the party on the couch.

“Heard you were talking shit?” He demands, despite the smile that was creeping up on his face. He caught sight of Midoriya, now pressing three fingers up in Bakugou– who was hard-pressed to stay upright, panting– and executed a full stop, expression dropping.

Sero rolled his eyes heavily.

Kirishima swallowed.

“Hey, Ei.” Denki nudged him. “Watch me drip out of Hanta.”

Kirishima made a strangled noise, echoed by the boyfriend in question.

“Baby you can’t just say stuff like that.” Sero swatted at him.

“Oh, sorry. Hey Ei, you should lick me out of Hanta.”

Sero moaned into Iida’s thigh, squirming.

“That is highly unsanitary.” Iida was sweating at just the idea.

“Deku if you don’t finish the fuck up I’m going to climb over there—fuck, fuck —and let four eyes finish the job. He’s got big fuckin hands and—”

Ochako slaps his ass rather perfunctorily.

“Be nice, Kacchan.” She says. Bakugou’s head whips around to narrow his eyes at her. Kirishima watches with baited breath and shark teeth digging into his lip.

“Why should I?” He challenges.

She brings her hand down to stroke over her pink silicone dick, kneeling on the couch, thighs spread wide to accommodate.

“Good boys get cock.” She said, only the faintest color flooding into her cheeks to belay the tone.

Izuku groaned. Shouto groaned. Bakugou swallowed a hasty moan.

Tenya felt absolutely light-headed. He made to get a bottle of water, right there on the table next to Kaminari and Sero, but found his legs abruptly weren’t keen to cooperate at all.

“Oh, here you go!” Kirishima scrambled to grab one; a complicated endeavor when he wasn’t quite willing to tear his eyes away from the scene.

He successfully grabbed a bottle with minimal fussing and presented it to Tenya, bright-eyed and blushing.

“Gotta stay hydrated, right?” He asked eagerly, laughing a little.

Tenya smiled back at him, unusually besotted over someone he wasn’t even dating.

“Thank you, Kirishima-kun.” He twisted the cap and drank half of it in several slow, measured pulls. When he glanced up, Kirishima was watching the bob of his throat with a slack jaw.

“Hey, it just occurred to me.” The redhead swallowed, blinking rapidly. “I totally never said happy birthday.”

“Oh, you needn’t trouble—” But Kirishima grinned winningly, climbing rather hastily into Tenya’s lap. He could only laugh in surprise, easily supporting his friend’s waist as his legs settled to either side of Tenya’s.

“So, happy birthday.” Kirishima beamed from two inches in front of his face, a lithe and lovely yet altogether predicably sturdy weight in his lap. He dipped his head to kiss Tenya, open and unashamed. Tenya was swept up in it, the warm and the wet and the wonderfully skilled press of lips and shy promise of teeth.

“Oh god, oh fuck! Move, you fucking nerd, I need your girlfriend in me yesterday, what the fuck.”

Kirishima disengaged the kiss with one last hot pull to Tenya’s bottom lip. They both turned to see Izuku roll his eyes and oblige his childhood friend, shifting until his broad, scarred back was facing both Tenya and Kirishima.

Kirishima bit his lip at the sight and proximity of it, or maybe because Bakugou was bracing both hands around Izuku’s neck, pressed chest to chest with him.

“Ochako was teasing him with the strap.” Izuku told them, likely at the slew of questions glistening in Kirishima’s eyes. They stayed glued to his boyfriend unerringly, even as Ochako lined up on his other side.

She leaned in, around Bakugou, and pressed a loving kiss to Izuku’s soft mouth.

“Get on with it, round cheeks!”

Ochako spanked him again, the sound ringing out.

“My cock, my rules.” She huffed, breaking the kiss reluctantly. She nosed against Izuku’s cheek before retreating, both hands settling on Bakugou’s ass. She spread him open.

“I think he could be wetter,” She said to Izuku. He passed her the lube.

She drizzled it onto her strap and pressed the blunt tip to his opening, one hand letting go of him to guide it around in loose circles.

His forearms shook over Izuku’s shoulders, fingers clasped together right in front of Kirishima, who leaned forward to kiss his knuckles reassuringly.

“Please.” Bakugou said, almost choked, and Tenya could see the way Izuku’s hands tightened hard on his waist for it, hips jumping. He would bet his boyfriend’s eyes were dark and gorgeous just now, mostly swallowed by pupil. He wished he could see.

“Well, since you asked me so nicely.” Ochako hummed. “How about ‘no ’?”

Izuku chuckled, a little exhale of breath.

“So mean,” Shouto panted, similarly delighted.

Bakugou made a strangled sound, like a whine that he forcibly closed his throat around before it could fully escape.

“Come on, ‘chako.” Izuku muttered, as though speaking up on Bakugou’s behalf would do anything other than enrage the blonde. “He’s being so good for us.”

Bakugou shivered a little.

He pressed up against Izuku’s boxers and the hardness within, grinding a little. Izuku’s hips began rocking slowly back.

“I don’t know if he wants it enough.” Ochako said, truly cruel. She shifted her hips and the angle until the head of her strap just pushed against the rim of muscle, but no further.

“What.” Bakugou swallowed, licked his lips. “What do I have to do.” He croaked.

Her face softened.

It was clear the joke had worn thin. Tenya shifted a little, not sure he liked this.

Of course, Ochako did not disappoint. His loving, beautiful, caring girlfriend!

“Kiss Deku, for me.” She decided. “Let him suck on your tongue, fuck your mouth a little. Then I’ll fuck you.”

Bakugou surged forward with zero hesitation, surprising even Izuku with his desperation. Izuku bore it well, though, steadying the blonde and taking control of the kiss, making it less frantic and more dirty. Tenya could see bits of tongue when they moved just right, could imagine quite easily from his own experience the way Izuku could slowly and forcefully fuck into your mouth until you were out of breath and squirming from it.

Kirishima panted softly in his lap.

Tenya shifted them until he could settle his chin over the redhead’s shoulder. It did, also, give him a better view. On the back of their couch, Shouto was resplendent with pleasure, slowly turning a lovely pink all over as Shinsou rocked into him.

They kept relatively quiet, a background serenade of soft moans and heavy breathing.

Tenya pressed his fingertips to Shouto’s hip, stroking with affection.

Bakugou and Izuku kissed like they were starving for it, but also like they had all the time in the world, and Ochako’s weren’t the only eyes watching with half-lidded appreciation.

Unspoken, something finally switched, and when Bakugou pulled back and cast his eyes to the side, avoiding eye-contact, Izuku’s face swelled with exasperated fondness and he lifted, just a little, shifting so the blonde’s hips were raised just so.

“Thank you, Deku.” Ochako beamed, lining up and pressing steadily in. The head of her cock popped in with little resistance, shaft disappearing between round cheeks.

Katsuki’s pupils dilated, lips parted, as she bottomed out in one slow, smooth, stroke until her hips cradled his, ample chest flush to his arched back.

Tenya smoothed one hand down Kirishima’s chest from behind, drawing in the other to feel his predictable hardness. He stroked along Kirishima’s hot cock for long seconds, relishing in the breathy sounds he made.

Then he let go.

“Here,” Tenya said, arranging them to his liking. It resulted in Tenya’s back once more being flushed to the back of the couch, sitting as one was meant to upon such furniture, and Kirishima more or less sitting on his right thigh, his knees flush with the back of Izuku’s heels.

“Oh, thank you!” Kirishima laughed, realizing exactly why his ass was now perched upon Tenya’s strong thigh. He was perfectly of a height to plaster himself along Izuku’s back and kiss his boyfriend, who fell into it eager and loud.

Izuku briefly froze, to be sandwiched between two very muscular and enthusiastically kissing men, but gradually relaxed and started grinding forward into Bakugou’s thrusts. At some point, Ochako had elected to start shallowly, sweetly fucking into him, and he kept pressed back into her and forward into Izuku, over and over.

Tenya let one big hand trail down Kirishima’s bare back, petting indulgently.

Shouto came with a startled little sound, eyes flying open.

“Oh,” He gasped, blinking rapidly. Shinsou chuckled and pressed kiss after kiss to his willing mouth, his softly flushed cheeks, before emptying into him with a little shudder of his own, pressing his face into Shouto’s neck.

He rode out the last few thrusts, steadily slowing down until he could hold still deep inside him.

Shouto got his breath back first.

“Thank you,” He said, cordial unless you knew to notice the completely besotted way his face relaxed, especially because he wasn’t ever going to smile outright. Shinsou pressed a welcoming kiss to his shoulder.

“My pleasure.” He grinned, all cocksure and functionally exhausted. The bags under his eyes had their own bags, a darker purple in color. Tenya made a mental note to find some way to get him a nap.

He pulled out of Shouto with a little grimace.

Tenya realized they hadn’t used a condom.

He bit his lip to avoid saying anything, although his own face did flush dramatically. Shouto, ever the attentive boyfriend, noticed immediately.

“I like the way it feels,” He admittedly quietly, which made Shinsou groan under his breath. “We did discuss it before hand, you know.”

“As long as you.” Tenya inhaled. “Discussed it beforehand. Fine. That’s fine.”

Shouto reached out and held his hand, squeezing reassuringly.

“You cool if I uh, pass out on the ground?” Shinsou questions, which makes at least three people on the couch sigh with relief.

“I left a stack of blankets next to Tokoyami for just this—hnng —occasion!” Ochako chirps, which makes Shinsou perk up considerably.

“I can make it that far.” He says, as if in surprise.

“That’s why I put them there, sweetie.” She beckons and he stops by her side of the couch on his way around, bending down to kiss her with some bemusement.

Izuku makes a bereaved sound, and Shinsou backtracks the foot or two it takes to press a sweet kiss against his panting mouth, only rolling his eyes a little.

“Love you,” Izuku grunts, which is usually a soft and fairly high sound. Currently Izuku’s voice is as low as it ever gets, out of breath and flexing his hips firm against Bakugou’s. Kirishima’s hardness pressed into the small of his back likely doesn’t help.

“You too,” Shinsou yawns, straightening. Tenya starts to watch him go, of a mind to make sure he doesn’t fall asleep in some truly absurd and unhealthy position like half-tucked under a table, but Shouto slips into his lap from the left, taking his free leg.

He nuzzles into the side of Tenya’s neck, cuddly and sated.

“Shoji,” Tenya whispers. “Could you throw us a blanket?”

“Don’t bother.” Shouto corrects, voice a tired murmur. “It’d just get gross, no one’s done yet. I got it.” He begins radiating a gentle, delicious heat, like a sauna or a bathhouse.

It seeps into Tenya’s muscles like a massage.

Tenya wraps one arm around his boyfriend’s middle, comfortable.

“How was it?” He asks, brushing his cheek across a shock of white hair.

“Mm. Good.” Shouto, always one of relatively few words, burrows deeper against Tenya’s side. Something wet leaks against his thigh and Tenya has to hold his breath, somewhere between mortified and outrageously turned on.

Shouto must sense it, because he pulls back to grin.

“I’m too tired to go again just yet, but we could always put on a show…?” He offers.

“H.” Iida clears his throat loudly. “H-how. Would you do that.” He manages.

“Hey, Kirishima.” Shouto barely raises his voice. “Make out with me in my boyfriend’s lap.”

Izuku moans at that, breathy and wanting.

Kirishima disengages from Bakugou with a hum.

“Yeah, sure thing bro!” he gives Bakugou an apologetic parting peck, kisses the back of Izuku’s neck almost like an afterthought, and then turns carefully to face Shouto in Tenya’s lap.

“Oh.” Tenya says dumbly. “Like that.”

Shouto radiates smugness.

“Yeah?” Kirishima asks, suddenly looking very interested. Shouto brings up a hand to cup Kirishima’s cheek, or maybe to grip his jaw, and then they’re kissing. Messily.

Right in front of Tenya.

Spirits, they’re kissing on his lap.

Tenya can feel his face burst into flames. He wants to cover it with both hands but that would disrupt them. He can feel each little shift as they adjust with their movements. He settles both hands on the back of their necks, so—

He doesn’t know why. He just does.

It feels, oddly, like he’s directing them, though of course he’s doing nothing of the kind. Shouto hums appreciation.

“Wait, fuck—” Bakugou complains, clearly unhappy about this change in arrangements, and Izuku bends slightly to kiss his shoulder.

“Don’t placate me, Deku, I can’t—” Ochako fucked a moan out of him, his body rocking forward slightly on the thrusts, forearms braced against Izuku’s shoulders so he could ride it out.

“I’m too fuckin’ loud like this.” He said.

“Want to make out with me?” Izuku asked. “Or I could give you my fingers, again.”

“Your fingers were in me, earlier.” Bakugou hisses, less than pleased.

Izuku rolls his eyes.

“I used a disinfectant wipe, obviously.”

“Like I want to taste alcohol, Jeeze, use your brain for once.”

“So, are you going to kiss me, Katsuki?”

“God, fuck, whatever. Just stop looking at me like that.”

“Like what?” Izuku grinds their cocks together slowly. “Like I’m stupidly fond of you? Like I love you? Like I always have?”

Bakugou makes a truly strangled scream and presses their mouths together roughly, claiming Izuku’s grinning lips in a kiss. Izuku huffs laughter into it, a few shameless giggles that melt into a low groan.

Bakugou breaks the kiss shortly thereafter, head thrown back and panting.

He exhales roughly, half-vowels and little oh s and ah s as Ochako fucks the breath from his lungs, settling into a punishing rhythm that curls his toes.

“Fuckin’ merciless!” Bakugou cries out, sounding impressed where he’s not literally fucked breathless, keening when she snaps her hips just right to drive into a sweet spot.

Tenya rubs his thumbs idly against two separate throats and feels his cock fill out slowly. He lowers his hand from Kirishima’s neck to wrap leisurely around his swollen cock. Tenya has large hands, but it’s never more evident than at times like these; the angry red head struggles to leave the confines of his fist, and Kirishima is no small man. Nor is he poorly endowed.

If anything, he’s on the larger side of average. Tenya just has really big hands.

“Oh fuck that’s hot.” Kirishima breaks the kiss to look down, watching the hand that dwarves him in its grip. He thrusts forward eagerly. Shouto settles one hand on Kirishima’s pec and mouths across his jawline.

A sweat breaks out at Tenya’s temple. He looks so good, paler than Kirishima by far; the line of his nose against Kirishima’s jaw, the way Shouto’s mouth works that indicates at least a fair bit of the indulgent, indolent press of teeth.

Kirishima’s hips jerk into Tenya’s fist. The flushed red glans disappears within his hold, rubbing along the ridge of each finger, and slides up again, struggling to push free.

Tenya rubs his thumb over it, when it edges out on the next few thrusts, and Kirishima starts cursing frantically under his breath.

“Oi, four eyes. You break it, you buy it.” Kirishima snorted loudly, both hands flying up to muffle the resulting giggles. Shouto pulled one hand out of the way so he could start sucking and biting down the column of Kirishima’s throat.

“Kacchan, be nice,” Deku admonished, rubbing his crooked thumb over a pink, wet lip. Bakugou’s tongue flashed out to wet it, eyes narrowed hotly. “It’s his birthday. This is for him.”

He ground their hips together. Tenya’s eyes slipped down to his boyfriend’s enclothed ass, shuddering a little at the idea of how wet his boxers must be by now. Some depraved part of him insisted he should press his mouth to the soiled fabric, get it nice and clean while Izuku whined above him; it even went so far as to conjure the imagined taste.

He does no such thing, of course; wild horses could not drag him out from under his boyfriend and his—Bakugou’s boyfriend. Sero’s boyfriend. Kaminari’s boyfriend. Mina’s boyfriend. Kirishima belonged to several people in the class and the redhead loved it that way.

“Right, of course.” Katsuki dipped his eyes in too-easy acquiescence, teeth flashing against Midoriya’s thumb. He tilted his chin over almost limply, fixing Tenya with piercing red eyes. The weight of that hung between them. Tenya felt a frisson of apprehension.

“Tenya ?” He offered, and Tenya fought a splutter. “Is there anything I can do to make your birthday better?”

His breath hitched as Ochako fucked slow and steady in and out of him, as Izuku held him still for it, pressed against his chest. Wet pink lips glistened, expression soft and hard and sharp all at once, but his jaw was slack with pleasure and beads of sweat dappled his neck, shoulders, pecs. He tipped his head back, eyes drawing shut, and moaned low and sweet as Ochako drug her cock over some nice place inside.

“Oh fuck,” Kirishima jerked hard in his grasp, coming all over Tenya’s hand.

Tenya felt his own cheeks pink heavily, yet dutifully kept up his ministrations until the tender flesh in his grasp quivered for mercy and Kirishima placed a warm hand, its forearm trembling, on Tenya’s large bicep.

“Oh—whew—that’s enough for me this round, Tenya-san.”

“Tenya-san –!” Tenya choked and his grip tightened a bit. Kirishima bucked into it, hips jerking involuntarily, but he also winced hard. Tenya let him go with a few parting, apologetic pats.

Then, hesitating only a moment, he brought his fingers up to the mouth that had started his ‘birthday party’ off with a ‘bang’—and oh dear, that was a pun, wasn’t it?— and had started a whole lot of other things, besides. Certainly, he’d begun any number of altercations.

Tenya tried to remember that frustration as he slid his wet fingertips along Bakugou’s soft lip. Bakugou, naturally, maintained half-lidded eye contact—rocking forward a little, as he was, with Ochako’s soft gasps and steady thrusts—and it seemed the thing to do to press down, a little, to part his lips as his jaw clearly wanted, all slack and loose and half-way to moaning, anyway.

Bakugou’s tongue swept slow over Tenya’s fingertips. He sucked the first two fingers slowly onto his tongue, sliding them back until they were squeezed into damp and warm and tight, and then Bakugou slid his tongue between them, lavishing the crevasse and webbing. Tasting.

Bakugou hummed lightly around his mouthful, whereupon Kirishima’s poor spent cock gave yet one last trickle of semen against his thigh.

“Please, don’t.” Kirishima groaned theatrically, still holding onto Tenya’s arm. “I’m already gay.”

He had twisted bodily around to watch his boyfriend, head and torso turning to the right as Tenya stroked him and Shouto stroked and kissed his neck and chest. Now he saw the admittedly prurient sight of Tenya’s fingers disappearing—rocking– into Bakugou’s mouth, fingerfucking him in a rather uncommon way, and Kirishima’s eyes had glazed over somewhat.

So had Bakugou’s.

Izuku took the blonde’s chin in hand and pulled him into a slow kiss, which was quite independently hot—watching their jaws move, the quiet intensity with which they pressed against each other, languid, unhurried—until Tenya realized Izuku was also inadvertently tasting Kirishima, a realization that hit when Izuku huffed a laugh and Katsuki gave a soft little moan, which struck Tenya like a delivery truck. He swiftly turned fire-engine red and had to stifle his reaction with both hands over his mouth; it was possible steam was coming out of his ears. Or possibly his leg engines. Shouto pressed his soft mouth against the back of Kirishima’s neck, in sweet parting, before shifting over to lean bodily against Tenya’s chest.

“You alright?” He asked, smiling. Tenya gestured with a knifed hand at the two. Shouto’s mismatched eyes followed with almost idle curiosity; they lit with slow heat to watch Izuku in this element. Izuku grinned into the kiss, dropping teasing pecks to Katsuki’s upturned mouth, and giggled a little when Bakugou moved to follow.

“Deku,” Katsuki threatened lowly, trailing off, warbling. Izuku moved a little closer, head ducking down, and Tenya’s hands fell to squeeze Shouto’s hips helplessly. He almost didn’t notice Kirishima slipping off his lap and into the floor.

“Kacchan,” Izuku murmured in answer, delivering one more smoldering, long kiss. As Tenya watched it melted into something hot and wanting; Izuku, breathing heavily, pulled back with lightly flushed cheeks. He caught Bakugou’s lip with his teeth, a slow tease, and Tenya felt his own groin stir despite his previous enthusiastic participation in earlier activities.

Shouto moved to get more comfortable. Ochako’s delicate fingers were visible on Katsuki’s slim hips, peaking around from behind, holding him steady. Bakugou was thrusting on-rhythm against Izuku’s toned abdomen, tilting his head up to demand more; Izuku’s bare scarred arms bracketed him, wide thighs rising from the couch and their knees; the blonde was red-faced and his throat worked steadily, panting.

“Are you teasing my boyfriend, Kacchan?” Ochako leaned the long line of her torso against him, lips pressed against the column of his throat, just behind his ear.

“Don’t fuckin’ call me—” He gasped out.

She bit him lightly; he jerked like she’d hit him, eyes flying wide.

“Are you teasing my boyfriend, Katsuki?”

“Holy god.” Kirishima muttered very quietly from the carpet.

“Hn-nn.” Bakugou tipped his head back, giving her better access. Izuku, never one to miss an opportunity, dropped a kiss to Ochako’s hair lovingly and then dropped his lips to mouth roughly at Bakugou’s throat, collar and jaw. Strokes of red followed, fast deepening to purple and blue here and there.

“Fuck, god, Deku.” Katsuki’s hands spasmed on Izuku’s arms, his back under the double assault. “At least your fuckin’ girlfriend is—hn, oh god, Angel —fuckin, sweet about it, you goddamn vampire.”

He pulls half-heartedly at Izuku’s mop of green hair.

Izuku sucks casually at the side of his neck, humming and unbothered, until Katsuki is almost trying to get away.

“Fucking come on, don’t make me—Deku!”

“Don’t make you beg?” Ochako pants out, sweating lightly. “Or don’t make you come?”

“Neither.” The word heaves out of beleaguered lungs, half-desperate. “I’m not fuckin’—”

Shouto was rocking against Tenya, now. Not out of any sense of urgency, nor was he particularly hard, but the scene was outrageously gorgeous—the picture they made!—and it was impossible not to react to it, to not take advantage of the friction and lazy pleasure.

Tenya rubbed against his boyfriend’s thigh, biting his own lip, unable to tear his gaze away.

“Oh god, Angel.” Bakugou cursed and Deku laughed against the fresh bite marks laved along his pec. He moved sensually, kisses and nips following his path, up to Bakugou’s ear and smiled against it.

“She doing you rough, Katsuki?” One hand tweaked the blonde’s puffy nipple. Katsuki’s thighs shook, Izuku right against him, just offset enough to give Tenya and Shouto—and Kirishima—a considerate view.

Bakugou whines harshly, hands latching onto Izuku’s shoulders, blunt nails digging in. Izuku drags his teeth against his ear lobe, a tease and the promise of liquid heat.

“In me, in me, you’re so–fuck!” He spat, abs and eyes squeezed tight, thighs flexing. “Fuck me, Angel, come on, come on.”  

“You gonna come for her? For us?” Izuku’s teeth traced the gentlest, breathiest line along the shell of Bakugou’s ear. “You gonna be good for us, Katsuki?”

Bakugou spasmed between them, pearl liquid beading atop his cock. His muscles shook.

“I don’t want to fuckin’—” Bakugou gasped rough, eyes blown, red almost entirely swallowed by pupil, clawing at the arms against him.

“Too. Bad!” With a punctuating thrust, Ochako slipped one of her hands around and—carefully—wrapped her fist around his leaking cock.

“God damnit!” Katsuki shuddered in her grasp, chest heaving, pecs rising and falling as he struggled to breathe, struggled between them, struggled to fight the inevitable. A steady litany of curses fell from his red-bitten lips for three, four and five strokes before he came with a broken cry all over Izuku’s tan thigh, head thrown back, suspended in a tangle between Deku’s scarred arms and her light brown ones, both strong and sure and taking his weight easily when he slumped.

“Sorry, honey.” Ochako said a few minutes later, once her abs had stopped shaking somewhat. “We kinda veered off from the theme there, at the end.”

“Don’t fuckin’ apologize for my kinks,” Katsuki hissed weakly, eyes narrowed—or barely open. He attempted to right himself, only to wilt against Izuku’s sturdy chest.

Izuku petted his hair with an indulgent and helplessly fond smile, practically glowing.

“Don’t you get smug on me, nerd.” Katsuki threatened under his breath.

Izuku grinned, subdued a little for how out of breath he was but no less radiant.

“Wouldn’t dream of it.” He lied.

“Hmph.” Between them they managed to manhandle Bakugou around with everyone’s limbs and dignity intact, the blonde only wincing a little as Ochako’s strap pulled at him. Then she was facing him, her perky bosom inches away from his ample chest, and Izuku’s eyes dipped down automatically.

“Good!” Ochako beamed, bending down to kiss him soundly. Bakugou folded around her like a sigh, a sheet of wet paper, a flower blossom tucking in.

He made a soft noise into it, approving—one that hitched and broke off into a cry as she moved in him. She pushed with her little hands until Bakugou put all his weight on Deku, more than half-way leaning on him. Izuku accepted the weight without complaint, ducking down to rub his chin over blonde hair.

The result, of course, was Bakugou sprawled back and Ochako leaning away– with the entire room able to see the bright pink cock sunk into him.

Or at least, the last inch or so.

“That’s arousing.” Shouto muttered, sotto voice, and Tenya swallowed hard, nodding. He buried his nose into his lover’s shoulder and when he dared look up again, Ochako was pulling her cock millimeter by millimeter out of his extremely reluctant opening, eyes half-lidded, staring him down.

“I’m never going to be able to unsee this.” Kirishima croaked.

“Same.” Izuku laughed, but his eyes, burning intense and watchful, belayed the tone.

“Idiots.” Katsuki’s breath hitched in the middle, hole clenching fitfully around her. “You see shit like this all the time.”

“Not in this combination, we don’t.” Shouto pointed out, amused.

“We really don’t, Kats.” Kirishima agreed fervently. Ochako, because she’s a little mean-spirited at the best of time, pauses halfway and gives a little teasing thrust forward that has everyone involved groaning around swears.

Her shoulders shiver.

“Someone really needs to get me off after this,” She complains, holding onto the revealed shaft so that she can pull the remaining bit out at leisure. It’s clearly deliberate, the way she wields the last two inches, catching and dragging against his rim. She bites her lip, adorably.

Bakugou’s softening cock twitches with overstimulation despite being untouched, for the moment—though Kirishima’s eyes land on it with an unmistakable hunger—and he holds onto Izuku with a curse and a threat.

“Angel I will fuck you up,” He promises darkly. Izuku’s hands light up with green lightning in a friendly warning, which ends in everyone shivering a little.

“Don’t threaten me with a good time.” She huffs, letting the head slip out of him with an audible pop.

Shouto untangles himself from where Tenya’s arms have somehow doubled around him, possibly out of desperation.

“If you take that condom of it and put on a new one, I’ll suck you off.” He offers, standing, stretching, and popping his back, as casually as one offers to get the lights.

Ochako, no fool, leaps on the suggestion.

”Sold.” She agrees, hurriedly going for the supplies, and Izuku groans dazzledly into Bakugou’s temple.

“Is it bad that I’m not even involved, and I think I might die from that?”

Tenya laughs despite himself and his suddenly empty lap, reaching over to stroke his fingertips over a freckled, strong shoulder reassuringly. Bakugou huffed, adjusted his sprawled legs—one foot arching against Iida’s knee—and leaned back to look at his childhood friend and rival.

“Fuck’s sake, nerd, I’m not even dating either of ‘em, and it’s still hot.”

On the far side of the ottoman, Ochako sat down breathlessly and Todoroki smiled with his eyes as he sank to his knees. Izuku buried his face in the junction of Katsuki’s neck and shoulder and tried to smother his strangled screams.

“Alright time for overwhelmed nerds to get the fuck off me.”

It took a few deep breaths, but Izuku huffed gamely.

“Fine.” He stood, strong thighs taking their combined weight easily, and tipped Bakugou right out of his lap without remorse.

Right into Kirishima’s waiting arms, naturally.

And, just as surely, it had been a calculated effort with gentle maneuvering.

“Hey!” Bakugou had no time to catch himself, but Kirishima caught him effortlessly.

“Hey.” Kirishima purred in greeting, performing a textbook emoji smile (if one could excuse the pointed teeth).

“Smooth.” Sero snorted, dropping down next to them. His back aligned neatly with Tenya’s shin.

Iida had no more attention for the three of them, though, because his boyfriend was shifting to lounge out on the couch, shoulder blades arched against the far arm of it, scars and shapely muscles perfectly on display. His toes curled sweetly against Iida’s hip, a small smile twisting up his lips.

“Hey,” He offered, looking—to borrow out of Ashido’s book—like a one hundred percent absolute snack. His penis stood at a patient half-mass, arched at an angle, and Tenya’s mouth unexpectedly started watering.

How embarrassing! He cleared his throat.

“Hi.” He said, but it came out at a higher pitch than it should have. He couldn’t look away from the unselfconscious sprawl, the gratifying confidence that the years had built up on his datemate.

Izuku crooked a finger.

Tenya found himself gently extracting his leg from Sero and crawling over, covering Izuku’s body with his own until they were in their own little world, heads ducked together in pseudo-privacy. Relief slid through him; he didn’t realize how much he needed a break until one appeared. Izuku wound his arms around Tenya’s neck with a delighted smile.

“Hi.” He parroted, ducking a grin. “Are you enjoying your birthday, Tenya?”

Tenya let his forehead rest against warm skin.

“I truly am.” He replied, quiet but no less sincere for it. He couldn’t keep the smile off his own face, happiness a warm weight in his stomach.

He closed his eyes for a moment, letting the giggles and breathless conversations wash over him—from their girlfriend nearby, from the hushed half ‘Bakusquad’ at the foot of the couch, and from all their other friends being safe and happy and confident all around the room.

He didn’t have to do anything but relax, because everyone was being safe and sane and enthusiastically consensual; he could let himself be taken care of, for once.

“Ohfuck really? Aren’t you tired?” Hagakure gasped with glee from surprisingly nearby. Iida turned his head a little to look; in deference to the rest of them, she wore little bits of accessories here and there. Notable pieces included: a choker necklace that looked to be from Tokoyami’s collection; soft and thin thigh-high socks that made Tenya want to avert his eyes on principle– despite being unable to see anything but the tiny, floating scrap of thong between them, and likewise despite the fact that he was currently engaged in fifteen-way act of group sex with her; it was the principle of the thing!—and, of course, the belly button piercing she’d gotten last year and meticulously kept neat and clean under multiple sets of watchful eyes.

He could pay attention to none of these things, however, because Sero was grinning wide and she was eagerly slipping onto her back on the widest, unoccupied part of the ottoman in front of the couch, clearly taking him up on some offer, the details of which Tenya couldn’t parse because she spread her legs, slipped off the thong, and a tiny purple vibrator was just visible.

Most of it, however, disappeared inside her.

“X marks the spot!” She giggled, making grabby hands at a perfectly willing Sero.

“Oh, wow.” Izuku’s voice trembled, breath fanning shaky along Tenya’s face. Tenya himself had to swallowed hard to avoid any unbecoming noises.

“Isn’t ‘the spot’ just a couple inches higher, doll?”

Hagakure’s hands—determinable by her fingerless gloves—covered her face as she squealed.

“Ahhh you called me doll!” She pressed fists to her cheekbones, clearly blushing, head shaking back and forth. Sero knelt on the floor between her legs, propping his chin up on her lower thigh with a shameless smile, despite the pink dusting his own cheeks.

“It’s because you dress so cute, you know?” He pressed his hands along the outside of her knees and worked up her legs toward her hips. “And you accessorize better than Mina, which isn’t easy because she’s so cute all the time—”

“Hanta!” Mina exclaims with delight from ten feet away. Unbothered, he continues.

“–with your long socks and your matching everything, you’re like a really pretty dress-up model.”

“I put so much effort into it!” She agrees, sounding out of breath.

“I know!” Sero says in the same tone, laughing a little. “You put a lot of work in and it shows! So, let me take care of you, babydoll.”

“Babydoll ” Ochako, Hagakure, and Ashido squee, the former gasping due to something Shouto is doing.

“Hanta,” Kaminari complains, trying and failing to stifle his helpless smile. “Bro, love of my life, you’ve gotta stop setting the bar so high for the rest of us!”

“What can I say?” Sero winks at Hagakure badly. “I’m the Best Mouth for a reason.”

And then, despite the incredibly amounts of fellatio he’d performed this evening, he dipped his head down and started teasing his mouth to where the vibrator—the vibrator!! —did indeed mark the spot.

“Isn’t your jaw sore?” Izuku asked in a hushed tone. Bakugou barked a laugh.

Sero pulled off from sucking on—presumably—where Hagakure’s thigh met her panty line.

“I’m dating Mina.” He said, puzzled, incredulous.

Kaminari and Kirishima laughed.

“He is the Best Mouth,” Kaminari elbowed Kirishima a little. Iida didn’t know when he’d come over to join his datemates, only that he fit snuggly between the blonde and the redhead like he’d never left.

“Yeah but like, he’s barely done anything tonight?” Kirishima asked, soundly genuinely puzzled.

“Look, just because our girl can go twelve times doesn’t mean—”

“Twelve times!? ” Izuku’s voice rose high and shocked.

“Interrupt me again and see what happens, Deku.”

Izuku ignored him with the ease of long practice.

“Wow, she could totally keep up with me!” Stars formed in Izuku’s eyes. He looked to Tenya in a hurry, worry taking over. “Not that, you know—”

“Nerd!” Bakugou snapped, because everyone within hearing distance was suddenly whipping around at them with laser precision. “Pause. Reel in the anxiety. Back up. Explain.”

“Ahah!” Izuku’s voice hitched into pure nerves. “About that, um. Ah. No?”

Tenya drew a reassuring hand down the nearest part he could reach, which turned out to be Izuku’s ribs and down his side.

“It’s not like they don’t already know most of it, anyway.” He encouraged.

“It’s private.” Izuku hissed, by which he meant it’s embarrassing! and the entire room could tell.

“Izuku.” Tenya pressed up so he could lift up off of his boyfriend, shifting his weight onto one elbow. “You know I respect your boundaries, of course, but it would be remiss of me not to point out that—”

“We are literally in the middle of a fuckin’ orgy, you useless—”

Ochako pulled Todoroki off her cock by the hair, leaned all the way across the ottoman, and punched Bakugou’s shoulder in warning. If he kept up with insulting Izuku, she would follow up with a real spar, and had threatened on occasion to ‘kick his ass like grass in a Denny’s parking lot’, whatever that meant.

“So, um. Huh. I guess everyone here does know about my quirk.” Izuku realized, eyes widening.

“It has been a number of years.” Tenya allowed patiently.

“It’s not like you can keep a fuckin’ secret to save your life.” Bakugou muttered rudely. “Speaking of: fuckin’ spill.”

“Aha.” Izuku swallowed, eyes darting around. Tenya kissed his cheek. He smiled.

“So it’s like this. Um. I’m a little bit. Multi-orgasmic? Is that the term? I have. A lot. Of, um. Energy. Because of the quirk.”

Mina arrived as if by Tenya’s own quirk, heels metaphorically smoking. She gently bullied Tenya out of the way and settled her hands on Izuku’s shoulders.

“Midori. Class problem child. Resident adorable cinnamon roll. Please tell me more.”

“What do you want to know?” He hedged, which was of course a challenge she could meet and beat. Her sense of shame had not magically grown-in during their final years at UA.

“How many times can you go? What’s your refractory period? Do you need a break between?” She got closer and closer to his face with every question, vibrating with excitement. “Can you match me ‘shot for shot’!?”

“Shot for—Ashido!” Izuku blushed bright red. Bakugou trailed a hand up her calf, restraining and enjoying all at once.

“This is serious business!” She insisted. “Katsuki can match me if we’re all involved because he’s the best, but being able to just go is. Wow. Not even the other girls match me because I’m a little bit crazy about it, apparently.”

“We love you!” Ochako called out, fluttering her fingers in a fond gesture. Mina blew her a kiss, not looking away.

“I um. So, we haven’t exactly measured.” Izuku explained, laughing now. “It’s not something we experiment with, you know? I can go as many times as my partners need, and then we stop.”

“Well, yeah, but how many times before you’re satisfied?”

“I’m always satisfied with my partners.” Izuku smiled, pink-cheeked and insistent.

“Yeah, but like. How many times before you felt like you didn’t wanna go again?” She narrowed her eyes at him. “Or until you couldn’t? Does it slow down the more you do?”

Izuku averted his eyes a little.

“Alright so usually when everyone’s all done, I’m all done? I just take a shower or wait for it to go down, or something.”

“So you’ve never reached the upper limit?” She got right into his face, excitement painted on every inch of hers. “You could, theoretically, outlast me? For all we know? Is that what I’m hearing here, Midori?????”

“I… suppose.”

Wary now, he glanced at her datemates.

“Oh, don’t let me stop you.” Bakugou spread both of his hands in a toothy challenge. “I got nothin’ to prove.”

“Best Lay,” Kaminari mutters, which makes Kirishima laugh so hard and suddenly that he chokes.

“That’s so fucking manly of him, though.” Kirishima hissed back, shivering with excitement.

“That confidence wasn’t there even a year ago.” Kaminari agreed. “Look at how much our boy has grown.” He wiped a fake tear.

“I’ll show you confidence.” Bakugou threatened, more-or-less playfully, and ended up pulling Kaminari into a flirty kiss over Kirishima.

“Iida-kun, happy birthday!” Ashido smiled at him. “Please move so I can climb into your boyfriend’s lap.”

“Oh, god.” Deku laughs. Tenya makes way and she climbs astride without hesitation. She does, however, look to him as Izuku’s hands settle on her waist.

“Oh, but this is supposed to be an Iidabang!” She frets. “Is it really okay to focus on Midoriya so much instead?”

“I want my boyfriend to have nice things.” Tenya assures her. “And he was correct when he mentioned we’ve never really ‘tested the limits’ of Izuku’s refractory period. It’s entirely possibly he doesn’t have an upper limit.”

“Ohmygosh!” Ashido squealed. “Oh, gosh, how do you not have fiveways all the time? There’s more than enough to go around.”

“It’s just not a thing we do.” Izuku presses a chaste kiss to her neck. She had thrown on a tee-shirt at some point—not the one she started the night wearing– and it’s all she’s wearing. His cock brushes her slick center.

“Why not?” She asks, breathless, as though she can’t imagine it. She clearly doesn’t want an answer, though, because she reaches down between them and lines him up. The head of his cock smears wet at her entrance and he groans.

She starts to sink down.

“Ohnowait—condom! Condoms!” Panic strikes through Izuku like lightning. Mina hisses and stops her downwards progress while he frets.

“So I know Class Prez wouldn’t be down for it, probably, but we got our Hero Licenses two months ago, which opened up Pro Hero medical options to us, and long story short I one-hundred-percent don’t need to worry about that any more because of Aevum’s quirk, so please, please fuck me like you mean it.”

Izuku’s eyes widened as he tried to take that in. His brain was like a steel trap of an encyclopedia, so he knew what Tenya did and more besides: Aevum, Pro Hero—Doctor (like Recovery Girl), capable of freezing time on wounds and medical issues, famously keeping victims alive long enough to get to emergency services, and not so famously putting a moratorium on long-term diseases until a cure could be found, though her quirk had to be re-applied every year and worked better on less-severe issues.

Because Iida’s mother was a Pro, he also knew that Aevum could put a halt to menstrual cycles and prevent eggs from even leaving the ovaries, which is just one of several topics about which he’s had a very thorough education.

“Um. Ochako?”

“My appointment is next week and it was going to be a surprise,” She winks over at them. Her hips are doing something odd and Izuku cranes his neck, a slave to his own curiosity, and feels his dick twitch violently inside Ashido when he realizes Shouto is, yes, sucking on her strap, but has also moved the base of it out of the way to finger her while he does it.

“We will need to have a serious talk about what everyone’s comfortable with,” Tenya mutters to himself, aping his datemate in this instance, but Ashido squirms and gasps.

“Midori, are you comfortable with this, right now? I kind of really, really need to know.” She sinks another inch down on accident and sucks in air through her teeth.

“I think it’s fine.” He takes a deep breath and snaps his hips up, sinking in fully, offering her a dazed smile. “I trust you.”

She bites her lip, flushing, and makes a little noise of gleeful surprise.

“Oh gosh you’re so sweet.”

Izuku can’t help but flicking a glance down at Bakugou. He is, after all, fucking his girlfriend.

Bakugou rolls his eyes skyward.

“It’s not like you haven’t fucked the rest of them.” He huffs. “Make it good.”

The ‘or else.’ lies heavy in the air, but Izuku smiles radiantly.

Ashido leans down to kiss him and then it’s all rather enthusiastic bouncing, groaning and Izuku’s eyes being unusually dark.

“Is it different?” She pulls back to ask, words gasp-y. His hands rise to stroke and pet her breasts, as she plants her hands on his shoulders and takes control of the pace.

“Kind of?” Izuku laughs, brazen. “Oh gosh. It’s just—wet. And uh. More real? Than the latex?”

Tenya has to look away and gather control of his breathing.

“It’s safe.” He tells himself. “It’s very safe, and very consensual.”

“Oh, what am I doing?” Mina demands, suddenly. “You’ve got super strength.”

She drags his hands to her hips and taps his wrist, meaningfully.

“Alright, but let me know if it’s too fast—we’ve got to be careful because the wrong move can hurt us.” He laughs, delighted, and the barest spark of lightning licks along his wrists as he takes all her weight with just his forearms.

“Oh that’s so much hotter than it has any right to be.” She fans herself, breath hitching as the pace kicks up.

“Right back at you!” He smiles, lopsided, as they set a rhythm between them that has them both out of breath and groaning.

“Wait, so you guys really never have fiveways?” Kaminari asks, curious. He tilts his head, which is surprisingly cute. “I mean, I know you’ve said that before, but—really?”

“Tsu is a lesbian and—oh, Sho!!– I’m the only other girl.” Ochako answers in her typical blunt manner. It’s only gotten worse over the years, likely picked up from Tsuyu’s incredibly honest nature.

“So, you strap her, and the boys strap each other—”

Bakugou bit Kaminari’s jaw in reprimand, which led to the boy moaning a little in surprise; a few jolts arced off his hands.

“We’ve done a few things.” Ochako ends that line of thought, cryptically. “We just don’t regularly have fiveways.”

On the ottoman, Hagakure tenses up with a low groan and Sero gives a few finishing touches before she’s pushing him away, almost swatting; he was clearly willing to continue almost indefinitely.

“Oh!” Izuku said, eyes flying wide in surprise as Ashido tipped over into an orgasm at more or less the same time. “Oh, hell, you’re so wet.”

“Oh fuck.” Sero’s eyes took in the sight they made, the sudden spasm of Izuku’s hips as he came in her. “Oh, fuck. What the fuck.”

He cupped himself and watched, but instead of pulling out, Izuku bit his lip and started a few tentative thrusts. Into the mess.

Tenya covered his face with both hands and tried to breathe. They were definitely going to have to sanitize the couch extra well tomorrow.

“It’s not too much?” He worries his lip in his teeth.

“No.” Mina insists, immediately, except it sounds like ‘Absolutely not, don’t stop.’ Her hands come down possessively on his shoulders as she rides his thrusts, and he picks up the pace to something like what they had before, fucking her through the aftershocks.

It catches and builds, because she’s not starting from scratch, and it’s not long at all before she dips her head back and yells, jerking erratically through a second.

“Oh doll, scootch over, I think they need the room.” Sero helps Hagakure to her shaky feet and she makes excited noises as Izuku stands with Mina. Mina’s noises are even more excited, because Izuku very carefully doesn’t slip out of her, and he lies her down on the ottoman.

His hands settle on her shins and press until both her legs come up, feet flat on the cushion, and that visual makes Tenya’s own penis pulse with something akin to jealousy. Izuku lets himself fall over her and catch his weight on his elbows, pupils blown fully wide.

“You’re so wet,” He squeaks. Indeed Tenya is close enough to hear a small squelching sound as he pulls slowly out of her. They all watch as the round head pushes back in. Deku is by no means small, but she opens around him easily.

“Ohmygosh.” Mina bits her own lip, looking down with the rest of them as he strokes in and out of her, keeping it slow. The wetness between them is of a slightly more opaque sheen than they’re used to seeing and it has no business looking as nice as it does.

Certainly it looks scandalous and Tenya’s blood did not need any help in racing through his veins.

Ochako reaches over to trail her fingertips down his arm. Izuku glances over with a distracted smile, only to groan as he gets a closer visual of what their datemates are up to.

“So that’s two to one.” Mina laughs, eyes a challenge. “Think you can win?”

“I think I can catch up.”

“You know.” Ochako says, idly carding her hands through Shouto’s red and white hair as he fucks into her with his warmer fingers. “I totally wanted a turn with you, Deku.”

His hips stutter with Mina and he groans.

“Like, with the strap?” He asks breathlessly.

She laughs.

“Yeah.” She confirms, sounding a bit overworked herself. Shouto slips off her dick and bends his head to the base of it, mouthing at her clit. “Mm. Wanted to make a direct comparison.”

“Oh, fuck you very much.” Bakugou snaps, raising his face from where it had been more or less glued to Kirishima’s chest.

“No contest.” Izuku snickered. “He takes it so good. I’d get too sore, too quick, and contrary to popular belief I try to avoid pain and injuries—”

“Demonstrably false, but continue.” Tenya finds himself muttering.

“—but like this?” He kisses Mina’s raised knee pointedly. “I can go all night.”

“I can go all night either way.” Bakugou huffs, then adds: “Not that it’s a contest.”

“Your therapist is going to be so proud of you.” Kirishima beams at him.

“No, because then I’d have to tell my therapist about the orgy. No, thank you.”

Izuku isn’t the only one who laughs.

“Not that I would ever say no to your strap, honey.” He looks over very quickly at Ochako and then, ears burning, back to Mina. Which doesn’t actually help, because while Shouto isn’t enthusiastically going down on her, she’s shimmied out of her shirt and her breasts are pink and gorgeous and she’s still tight around him and grinning shamelessly.

“Oh no, huge same.” She laughs. “Ochako, you feel free to bring that sexy thing by, whenever.”

Ochako took her shaft in hand pointedly, giving them a little pose, and Izuku’s eyes tracked the motion as she rubbed the spit-slick tip over Shouto’s high, pale cheek. Shouto looked up in a touch of surprise and snorted, to realize her game, but his smile was full of fondness as he turned his head and pressed a chaste kiss against the silicone.

Izuku shuddered through an orgasm; Tenya and all the others had a perfect view of his backside and back, and arm muscles, for that matter, as they trembled. It was a nice back, of course; everything about Izuku was nice and nicer looking.

He came down blinking; Ashido stared at him with excitement and something gentler pinching about her eyes.

“Again?” He asked, once more biting his lip.

She mirrored the motion, white against dark pink, eyes wide, her lower lip full and flushed, and nodded almost shyly.

Izuku thrust forward and they both stopped to groan.

“That’s so…” He starts, blushing hard.

“Oh man.” She lifts one hand to cover her face. “Oh man, I’ve totally been with my boys, obviously and logic says we should have done this at some point, but I somehow don’t think we did?”

Izuku pushes into her again and Tenya can hear the slide and slick of it, messy and wet.

“That sound is going to keep me up at night.” Kaminari says, idly yet clearly much-affected.

Shouto fingered their girlfriend through a relatively long orgasm, until she was tapping his shoulder to get him to stop. He rested his head on her substantial thigh, pillowing his cheek there; red and white strands of hair lost their center part and wisped around his flushed face.

Deku leaned down onto his forearms and kissed Mina.

She hummed into it, gasping.

They rock together, Ashido clenching around him like she’s not gushing, Izuku thrusting hard and trying to hit the perfect angle.

“If you can go forever, won’t you just get tired first? Like, your legs?” She breaks the kiss to gasp. Izuku looks at her, puzzled and a little sweaty, before laughing out loud.

“I spent a year doing strength training with All Might before UA and we kind of never really stopped. Also, I have a stockpile quirk.” He kissed her again, soft, slow, and pulled back to grin, more than a touch wry. “At this point it’s safe to say my dick will fall off before my legs give out.”

“We live in the best timeline.” Mina grinned, arching under him. He hummed agreement and bent his mouth to lap at her breasts.

Ochako got off on Shouto’s fingers, crying out, and he slipped gently out of her, wiping his face on someone’s discarded shirt.

“Oi, fucker.” With Bakugou’s discarded shirt, apparently. Shouto shrugged at him.

“Come get off with me, half-n-half.”

“Pass.” Shouto snorted, standing and stretching easily. He pressed a soft kiss to Ochako’s hair and she practically purred. “I mean, I would—don’t get me wrong, I love getting the chance to shut you up—but it’s Tenya’s birthday and I think he needs another ‘turn.’”

“Fair-e-fucking-nough.” Bakugou rolled his shoulders. “You good for some sexy rubbing, Sparky?”

Kaminari laughed, nodding. “Anything for a datemate.”

“Oh, anything, huh? Careful what you go around promising.” Bakugou snagged him by the collar of the shirt he hadn’t taken off yet, somehow. “Not everyone is as nice as me.”

“What if I don’t want you to be nice?” Kaminari breathed, widening his eyes. “I knew what I was getting into.”

“Oh, really?” It devolved from there, with Kirishima finding some way to get in on that—at the very least, the red head did not bother to venture away—and Tenya was suddenly very much more occupied with the boyfriend pressing close to him, tasting like Ochako and latex.

“You know, I’m probably still wet and stretched enough from earlier.” Shouto observed, idly.

“Hrk.” Tenya had to blink a good many times at the implication. “We would still need additional lubricant.” He warned.

Shouto’s mouth pulled up in a half smile.

“Yeah, I know.” He said, leaning in for a nose-brushing kiss. “You’re so good at taking care of us, Tenya.”

Tenya flushed hot.

“You always know exactly what we need.” He trailed his hand down Tenya’s torso and wrapped around his cock. “Is there anything you need, Tenya?”

He leaned close to whisper.

“I have everything I want.” Tenya admitted, easily. “It’s been an unexpectedly lovely birthday.”

Shouto flushed a little, pleased.

“Have I ever told you I like how big your hands are?” He asked, blinking a little. “You can cover a significant portion of my waist with them. I look so small when you hold me there.”

He said it so matter-of-factly!

“No.” Tenya choked. “You’ve never mentioned.”

“Sometimes all I can think about is how easily you could pick me up; how much bigger you are. It’s exciting.”

At his lover’s encouragement, Tenya slicked up two of his thick fingers and worked them inside. Shouto’s hands clenched tight on his shoulders, chin tipped back as he breathed—panted—through it. He was, Iida was scandalized to note, still very damp inside.

“We need a condom.” Tenya’s mouth said, and Shouto blinked slowly at him, offering a lazy smile.

“If you want.”

With a strangled sound, Tenya reached out and someone—Ochako—placed a condom into his hand. He was deeply affected by all this relatively sudden forgoing of traditional safety measures, as careful as they were and as true as it was that they were all ‘clean’.

“I’ll think about… alternatives… later.” He informed Shouto quietly, who pressed a reassuring kiss to his forehead.

“Don’t worry about it, Tenya. I only want what you’re comfortable giving me.”

Tenya placed the condom on and carefully lined up, sliding in with minimal resistance as his boyfriend breathed deep and bit his lip in Tenya’s lap.

Next to them, Izuku got Mina off with a particularly clever series of thrusts, and leaned down to kiss her in victory.

He caught her slack mouth, molding their lips into a more traditional kiss, and–still dazed from orgasm—it took her a moment to get with the (unexpected) program, but a moment later it was Izuku who sat up with surprise. He shifted his weight onto one arm with no issue—Tenya and Shouto groaned —and brought the fingers of his free hand up to his lips, touching them faintly.

“Mina?” He asks, blinking, and she struggles to focus her eyes and leave the haze of pleasure behind.

“What? Oh!” She sees his hand touching his mouth. “I’m so sorry! I haven’t forgotten something so simple since I was literally like, twelve.”

She covers her own mouth with both hands, which is adorable due the fact that she’s still split open around his cock.

“What was that?” He asks, curious. “Your quirk?”

Embarrassed, she nods.

“I have to regulate the PH balance of the acid in my mouth or it tingles like that!” She huffs, blushing a bit purple. “It doesn’t hurt, one or two people have said it’s just like, Pop Rocks—you know, the old American candy?—but I kind of got used to ‘fixing’ it twenty-four/seven, you know. Surprise kisses.”

She winked at him. He dutifully provided a surprise kiss. The movement caused him to, well, move in her and they both moaned a little at the unexpected shift.

Suddenly, Kirishima was there.

“Did I hear that right?” He demanded, grinning ear to ear. “Does my girl have a quirk kink?”

“We all have at least one quirk kink.” Kaminari pointed out, sitting up from Bakugou with his hair all wild. “Mostly it’s for my quirk.”

“Denki, I love you. Now is not the time. Our girl has a quirk kink!”

“Oh, oh!” Kaminari smiled brightly. “If it feels like a literal tingly sensation when you kiss—the genuine sparks, bay-bee—then does it feel tingly on your dick?”

They look down to where Izuku is sheathed inside her.

“I’m not making acid with my vagina, for the thousandth time!”

“Okay, fair—” Izuku relaxes with relief. “—but oral? We have got to try that sometime!”

“You know what?” Mina’s expression goes through a journey. “You’re right. C’mere.”

Kaminari abandons Bakugou—who makes a noise of protest–and nudges Kirishima out of the way. Bakugou accepts his consolation prize with dignity and Kaminari holds his dick in his hand while Mina maneuvers up onto one elbow into a kind of twisted plank.

She kisses the flushed tip.

“Oh!” Kaminari jumps a little. She licks carefully around the head, then pulls back to check in.

“Good?”

“Yeah!” He says, surprised. “It’s like hot and cold lube except doesn’t get way too ‘hot’.”

“Tingly For Your Pleasure,” Mina paraphrases, winking at him, and Kaminari’s delighted laugh shifts into a groan as she sinks onto him fully, echoed by Deku a moment later as she must clench around him somehow. He makes it a few thrusts before the laughter and joy catches up with him and he comes, tensing.

“Oh!” Mina pulls right off. “I just had the best idea. Wait, first—can you go again?”

Mutely, Izuku nods. He offers a shaky smile.

“Excellent.” She holds onto Kaminari’s cock with her free hand, which looks exactly like something she’s doing because her mouth is busy talking and she didn’t want to leave him hanging there. “So, I just realized—no fiveways is one thing, but no fiveways with Kami means no quirk kink. Specifically, no Kami- specific quirk kink.”

“Y-yeah.” Kaminari shoots finger guns, pulse jacked up from the pink hand idly stroking him. “You’re missing out.”

“No, hon, they are. They’ve never sparked up and got off together!”

“Wait,” Izuku pulls out of her. “Are you saying you guys come together-together? Like, at the same time?”

They pause a moment to watch the built-up mixture trickle out of her. Mina’s throat is not the only one tight when she answers.

“Yeah, exactly. It’s the only way to really end the night, you know? Everyone going off at once.”

Kaminari catches her meaning exactly, stroking his chin.

“So I probably can’t get everyone but I think I can get the whole ‘Crew, as long as we’re touching or near-touching and everyone’s fucking somehow.”

Mina nodded, determined.

“We can do it!”

“Yeah,” Kirishima snickered, breaking a kiss with Bakugou. “Plus Ultra, or something?”

Bakugou rolled his eyes and pulled him into a deeper kiss.

“Oh god this is the best day,” Kaminari sighs. “I can’t believe Mina’s been holding out on us.”

“No!” Mina protested, laughing.

“Our own girl being stingy with the goods this entire time.” Kirishima lamented. “Quirk kink, Mina, really?”

“I forgot!” She hollered. “I didn’t think this counted!”

“They’re never going to let you live this down, Acid.” Bakugou grinned, eyes soft. “Might as well just accept your fate.”

“I can’t wait to get everyone’s quirk kink going at the same time.” Kaminari’s eyes lit up. “I know it’s more Ei’s thing, but—”

“Speaking of ‘going at the same time’!” Mina interrupted, eyeing him pointedly before lowering her mouth back down to work.

“Oh, right!” He laughed, genuinely enamored, and she gave him a thumbs up.

Kaminari looked to the ‘Izucrew.’

“You guys good if I spark you up? It’s tried, tested and true—and Bakusquad approved!” He cackled to himself about the rhyme.

“I suppose if you really have been doing it safely for years now.” Tenya allowed, already sweating at just the thought of it. Shouto was hot like a vice around him; he bottomed out as he spoke.

“Oh, man, birthday boy approved!” Kirishima high-fived his datemate; Kaminari had donned a megawatt smile.

“Midoriya? Uraraka? Todoroki?” He checked. Shouto gave him a flushed thumbs up.

“I think I’m good.” Ochako agreed, smiling. “Tsu, hon?” She asked, for the Rainy Day Hero was walking over.

“If you are very careful, kero. Frogs are usually water-types, you know.” The Pokémon reference landed for everyone there and she smiled, pleased.

“I’ll be super careful.” He promised. “Also, I’ve got a lot of practice. Like, years of practice at this point. You’re in good hands.”

“We trust you.” Izuku offered, smiling gently. He edged back just enough to stroke his cock against Mina’s clit until she came, unexpected but not unwelcome, and nobody begrudged him the several-second pause.

“Who’s going to do… what?” Izuku asked, blushing. Mina’s head fell back, stunned.

“It’s alright, nerd.” Bakugou rolled his eyes. “You can say ‘who’. Who’s going to do who ?”

“Well, I didn’t get my “Best Lay,” earlier—as lovely as you are, Shouto, obviously no offense–”

“None taken.” He promised, voice shaking with the effort of staying still, impaled as he was. Tenya’s own thighs shook and quivered from the monumental effort.

“Well, those two are squared away.” Bakugou laughed. “We should be quick, then?”

“It would be… appreciated.” Tenya ground out, sweating.

“So fair’s fair and I’m with Angelface, Icyhot with Class Prez, Acid’s giving Sparky the tingling-suck-off of his dreams—Ei?”

“I’ll keep Izuku company.” He volunteered, with a small smile that Izuku returned.

“Traitors on all fuckin sides, I swear.” Bakugou huffed. Kirishima knocked their foreheads together gently, and the grumblings tapered off.

“Oh, but what about Tsu?” Tenya asked, concerned that she might be left out. The notion of participating in this with all of their datemates—and participating with all of them, together, in one act—was incredibly beguiling. It would be like he was… indulging… with all four at once, somehow.

Tsuyu looked at him hard for a few moments, turning something over in her head.

“Alright, I’ve decided what I’m comfortable with.” She announced, in a familiar tone. She walked to Izuku’s abandoned place, more or less, and took to her knees. Maintaining eye contact with Tenya as she took hold of Mina’s legs and tugged her closer, Tsuyu said:

“I’m doing this for your birthday.” Her dark eyes didn’t blink; Tenya was not the only one who shivered for the intensity. She tilted her head, grinning wide. “And because I want to have sex with you all in a way that’s not uncomfortable, kero.”

“Tsu-hon!” Ochako cries out, overwhelmed with love for her girlfriend. “How are you so perfect?”

“I must have gotten it from you.” Tsu smiles. Then she bends her considerable tongue and licks Mina’s dripping cunt, personally turning Izuku a bright and immediate red, unable to speak.

Mina looks overwhelmed for only a moment before she takes Kaminari back into her mouth.

He whines.

“Mina, my love, please use your quirk.” He laughs.

“Whoops, sorry.” She pulls off to apologize. “It’s hard to do it on purpose!”

“Don’t worry about it.” He offers a crooked smile, encouraging. “I’m just excited you’re trying it out.”

She starts sucking him off. He starts sparking them up.

Tenya starts moving Shouto in his lap, fulfilling the request for handling.

Ochako throws her arms around Bakugou’s neck and sinks onto him with a relieved sigh.

“I’ve needed something stretching me since I first put on the strap, it’s such a tease.” She admitted, to which he grinned in reply: “I don’t know, I liked it pretty alright.”

A little shiver went through them, quirk-artificial, but a moment later another followed, little jolts of pleasure that lined up with their various thrusting hips.

Kirishima took his own cock and Izuku’s still-wet one into one of his hands and stroked them off together, easily catching and riding the rhythm of Kaminari’s ‘sparks’.

One by one they built up to their climaxes, and one by one their pleasure drug the others closer, heartbeats synchronizing. Ten people jerked with simultaneous orgasm.

“Oh, wow.” Izuku laughed, the first to recover. Mina made an inarticulate noise and threw herself to his arms.

“Again, quick, I can usually get three after a proper spark-up.” She insisted and his eyes lit up at the challenge, rolling them.

“Well, fuck.” Bakugou said. He eyed Ochako up and down. “He’s pleasing my girlfriend, so why don’t you sit on my face already?”

She eyed him right back. “Yeah, alright. Get rid of the condom and lay down.” and mere moments later she swears loudly: “Mina, what the hell, they do have unnatural stamina!”

“Sero has Best Mouth, officially.” Mina laughed, already bullying Izuku back inside of her. “But they’re all really, really dedicated to keeping up with me.”

“Let’s see if I can’t really keep up with you,” Izuku laughed, and laughed even harder when Bakugou’s hand rose up from under Ochako to flip him off.

Tenya slipped out of Shouto, who was at this point so swollen his insides didn’t want to let go, and hugged his boyfriend close to him. People—Tsu, the unoccupied boys of the Bakusquad, and Tokoyami, Shoji, Ojirou and Hagakure—reached out to touch him, offering praise and kisses pressed to his hair, pats on the shoulder, but he was hardly in the frame of mind to thank them properly.

“Happy Birthday.” Said everybody who passed, smiling indulgently, and Tenya didn’t realize he was falling asleep until Ochako’s alarm jerked him out of it, and Shinsou’s unexpected hand offered him his phone.

The room was dark and quiet; some people had meandered back to their rooms, but everyone Iida was dating was present and accounted for. His heart warmed immediately.

“We can’t miss check-in.” Shinsou explained, smiling softly; not as sardonic as usual, something softly real in the gentle dark of the common room. “Well, we can, but are any of you prepared for what I’d have to do to get Aizawa off our backs?”

The smirk appeared.

“Aizawa is not a DILF.” Izuku protested sleepily from where he was curled up into Tenya’s side.

“Not to you, maybe.” Shinsou snorted hard. His smile softened. “We should do this again sometime, Class Prez. It was fun.”

He deliberated with himself for a minute before something won out; he leaned forward and snuck a quick kiss onto Tenya’s lips, pulling back just as fast, red-faced.

“I’m glad you agreed to tonight. I hope you enjoyed it as much as I did.” Shinsou said, as sincerely as possible, and Tenya blushed himself as he unlocked his smartphone.

He did a quick headcount and typed out the required message with sure fingers, finally letting the phone drop safely back to the table beside the couch. Someone had drug the ottoman closer so that everyone could more or less be on it or the couch, or both.

Tenya held out a hand.

“Join us.” He offered, and once more he watched Shinsou waver. Once more the purple-haired team overcame whatever reservations he harbored.

“Yeah. I think I will.” He ended up jammed between Shouto and Tenya, half on the birthday boy’s lap, but they didn’t seem to mind so neither would he, he decided.

“Goodnight.” Tenya whispered, as his phone screen went dark, pitching the room into perfect darkness once more.

“Goodnight.” Shinsou answered quietly, curling close, and: “Happy Birthday.”

Yes, Tenya thought to himself; it rather was, wasn’t it?
