Proud Immortal’s Demon Waif

Title: Take Solace
For: Uintuva
Category: Crossover, Scum Villain AU, PWP
Ratings: R
Pairings: Hatake Kakashi/Senju Tobirama
Words: 3,037
Warnings: This includes a brief dub-con premise (Kakashi thinks of exchanging sex for safe passage/his life), but everything is entirely consensual between them. Kakashi is a sex demon who has a physiological need for yang energy.
Note: This is for Uintuva, who is very much captain of this ship. It’s a cross over with MXTX’s “Scum Villain Self-Saving System” but not much knowledge is required. Just that Tobirama is in charge of his section of a mountain school for magic/cultivation in the setting.
Summary: When his sources tell him Peak Lord Senju Tobirama is away on a night hunt, succubus Hatake Kakashi decides to slip in for an easy meal amongst the student cultivators.

The only problem? He was set up, and Tobirama is not amused to find a demon on his mountain. Perhaps, however, he can be persuaded to let Kakashi go… if he behaves.


Translation Notes:

Uintuva asked for a succubus Kakashi AU, and we mutually agreed that Scum Villain already had the perfect set up. Any ridiculous bits (booty shorts on people in this setting) are intentional and not my fault; we’re blaming Airplane Shooting to the Sky, here. It’s Shang Qinghua’s world, I’m just writing in it.

With regard to translation: I’m by no means a Mandarin speaker, but I did play around in google translate to Naruto-ify the setting. It’s Cáng Yèzi Cultivation Sect, which roughly translates to hidden leaf/leaves.

Jiāo Yān, Tobirama’s cultivator sword, is meant to be using the characters 蛟淹. I don’t know if that makes sense as an actual word/phrase, but the individual characters, I chose for “jiāo–a legendary dragon with the ability to control rain and floods, see also 蛟龍 | 蛟龙 [jiao1 long2]” and “yān– to drown.”


Kakashi wasn’t– quite– starving. Sure, it had been months since he had a good meal. And sure, the ‘good meal’ in question had been barely tolerable, ‘good’ only by the standards that he’s comparing it to the scraps he’s used to.

But he wasn’t starving! He was just tired of barely getting by, of the constant craving going unassuaged. He may not be starving, but he was so tired of being hungry.

That’s how he got himself in this predicament. Tits pressed into the cool, soft earth, half-decayed leaves digging into his bared stomach, and a strong, big hand tangled in his hair and forcing his chin back.

Merciless.

Of course, that’s what they always said about Peak Lord Senju– the second one, not the Sect Leader. They said he was cold and ruthless on the battlefield, short-tempered and as capricious as the storms he called to hand, and that you’d sooner get blood from a stone, than pity from Senju Tobirama.

So Kakashi knew better than to beg for mercy, now that he was caught; there would be none to find. He ran first teeth and then tongue over his lips, nervous. Afraid.

“Ah, I don’t suppose we can talk this out?” He asked, gulping when his head was yanked back further. Kakashi’s whole body froze as he felt the kiss of steel to his bared throat.

A knee pushed into his back, keeping him pinned, and it took all he had not to squirm. Fuck. His mouth fell open. 

“No.” Said Peak Lord Senju, voice hard. Kakashi didn’t have any particular god to pray to, but he began seriously considering his last moments in this realm. In any realm, actually.

It was a knife, at least, and not a pale blue sword flashing in the moonlight.

Even a demon as lowly ranked as Kakashi knew of Jiāo Yān, the deadly and beautiful sword of the second Peak Lord of Cáng Yèzi mountain sect.

He was thankful for the lesser blade. Few had seen Jiāo Yān drawn and lived to tell about it. Granted, that didn’t make his situation any better; there was a reason the sword was dangerous, and it wasn’t because of the metal but the wielder. There was a reason the peak lords were named for their weapons.

Jiāo Yān remained in her sheath, but the Jiāo Yān Sword, Senju Tobirama, was still about to kill him where he lay.

Unless Kakashi could entice him not to.

Well, if he was going to die anyway…

He let his head fall back further, pushing his carotid closer to the knife.

“Please.” The word fell out of Kakashi’s parted lips like petals falling to the ground– whisper soft and mesmerizing. 

Incredibly– miraculously– the peak lord paused.

“Surely you’re not begging for your death.” Senju said.

It could be argued he’d asked for death by even coming here, even when his sources– who he now realized were definitely trying to set him up– had said the peak lord was ‘for sure’ last seen on the other side of the country, attending a night hunt personally.

Dirty fucking liars, all of them, and he was going to have to revenge himself as soon as he got out of here. If he got out of this.

Kakashi was wearing what he thought might appeal to some young, green cultivation students at the educational peak. They have less martial ability, more book learning. More draw to the forbidden.

Probably arrogant enough that they thought they could outsmart a lowly succubus, too– which he was relying on. Still, the outfit couldn’t hurt. He was wearing tiny shorts that practically outlined his cunt, and a top that cut off above his pecs, which was why his tits were currently in the dirt.

The only “concession” he’d made towards humanity’s ridiculous standards of dress was the long stockings that covered his legs up to mid-thigh, and the long sleeves of the top, a matching sheer black material that stretched down each of his individual fingers.

Well, nothing else for it.

Kakashi had to bank on the fact that his ass was half out.

“No,” He gasped, turning bright, wide silver eyes on the cultivator. “Please, I’m so empty.”

Not begging for his death, but for a little one.

The pressure of the knife vanished. Before he could celebrate, however, Kakashi found himself being flung onto his back. His shoulder blades hit the ground harshly.

His higher brain functions flipped right off, lizard-rhino brain sitting up in excitement. He was already wet.

“Are you alone?” The peak lord asked, seemingly already knowing the answer. Ah, fuck. An interrogation.

The lizard-rhino part of his brain absolutely purred: oh, yes, an interrogation. Maybe he could be punished if he didn’t give sufficient answers…

Hesitantly, Kakashi bit his lip. He nodded. Red eyes bored into his, searching for any trace of dishonesty.

Kakashi let his legs fall open on either side of the cultivator, moaning once more. It wasn’t even faked; the man had knelt over him, positioned more or less between his thighs. Kakashi was just encouraging the natural way forward.

“Hmph.” Senju laughed, low and amused. “You’re not here as part of a demonic excursion at all, are you?”

Sometimes, up-and-coming demons wanting to make a name for themselves– especially in the North– would come into the human realm and challenge the cultivators. Kakashi had never seen the fucking point, personally, but he’d always preferred fucking to combat.

Really not.” Kakashi trembled. “Please, I wasn’t going to hurt them. Cultivators have so much more energy…”

Tobirama leaned forward, pressing his thigh against the molten core of Kakashi. Every nerve ending in his body seized up. It had been so long… so long…

“You made a mistake, going after my students.” The man said, voice dangerous. Kakashi could barely hear him, even so close. “But seeing as you didn’t mean them harm, I’ll let you live.”

Please!” Kakashi didn’t want to live if it meant going away empty handed, if it meant leaving this.

“Don’t worry.” The peak lord said. “I’ll make sure you learn your lesson first.”

Oh, thank fuck.

He rocked his knee ever so slightly and Kakashi keened for it. He should probably be ashamed of himself, but adrenaline and fear had left a cocktail of endorphins rushing through his body, and it sang alive—not in mortal danger but in excitement.

Tobirama was so hot and solid against him, a delicious pressure. Kakashi could sense him; a burning sun of energy. So this was an immortal’s golden core. Whereas a human had only sparse life energy, which a succubus such as Kakashi could only steal, cultivators had cultivated into massive amounts of the stuff. The difference between a cultivator such as Tobirama and one of his students was profound; he was so far removed from a farmer or tradesman that he might as well be a different species.

And all of that delicious power was hovering over Kakashi, watching him come apart for the simple touch. Kakashi flushed hot, a hysterical laugh building in his throat.

It was like standing in front of a bonfire. Like fucking one.

Tobirama was hot enough to melt the whole damn North.

Kakashi reached up on instinct, curling around the point of liquid pleasure. Surprisingly, Tobirama allowed it; he clung to Tobirama’s shoulders and moaned, rocking into it.

“Needy.” Tobirama huffed. “Then again, I suppose you must have been desperate, to come here.”

“Yes, yes, let me come.” Kakashi gasped, feverish with it. The sun in human skin moved around him, touching him, filling him; the passive energy Tobirama was allowing himself to put off— just the aura of it—was a better meal than Kakashi’d had in ages.

Perfect , he thought deliriously. Excellent, exactly as planned.

Tobirama indulged him for a few moments, keeping up a steady rhythm as Kakashi writhed, and then pushed him away. Strong hands took his shoulders and pushed him to the ground. Kakashi looked up at him, black almost overtaking the silver of his eyes.

The red gaze narrowed, a small smirk lifting the corner of his mouth.

“Yes, you need me badly.” Tobirama murmured, shifting accommodatingly until his hips parted Kakashi’s legs properly and his cock replaced his thigh. The hard line of it aligned perfectly with him through their layers– Tobirama’s several and Kakashi’s ‘skimpy’– and pleasure rendered Kakashi’s thoughts into a white buzz.

“Oh, yes.” He agreed, reaching blindly once more. Tobirama’s hands closed around his wrists, pressing them into the leaves, and Kakashi’s mouth fell open on an approving moan. He tipped his hips, encouraging.

Tobirama used his hold as leverage, thrusting firmly against Kakashi. His cock slid sweetly along his slit, slow and firm. When he reached Kakashi’s cock, he moved into short, torturous strokes– more massaging the small organ than anything else.

“Lovely.” Tobirama proclaimed in his low voice, penetrating the hot fog of Kakashi’s thoughts. “Look at you– you’d do anything I asked.”

“Anything.” Kakashi agreed, panting. “Please.”

“You need not beg me for it.” Tobirama said, amused. “I’m going to give you what you need. What you crave. Although… you do beg sweet, don’t you?”

Kakashi let his head tip back, lips parted. He begged with his eyes, giving Tobirama his surrender– the cessation of thought, of any resistance.

“Oh, gorgeous.” Tobirama slid his hands down Kakashi’s wrists, tracing the fragile veins there. Gooseflesh erupted in his wake, all the way down. Tobirama slid his rough palms along the flesh of Kakashi’s tits, cupping them, and Kakashi arched into it– but left his hands exactly where they belonged, where they were placed.

“Yes, like that.” The man allowed, a rumble. He thumbed over pert, aching nipples and Kakashi moaned shakily. The cock against his slit was everything, burning pressure and felt larger than anything else– more present than the hands at his chest, than the cultivator on top of him, than the world under him.

His focus narrowed down dangerously. Kakashi slid his teeth into his bottom lip, clenching in time with the rocking thrusts. It took the whole experience up into a maddening tease. He was soaking wet; his cock, throbbing.

“I need you.” He gasped. Part of surrender was honesty; he did not own the thoughts in his head, his wants nor needs. Tobirama owned all of it; for the moment, Kakashi belonged to him. “Inside me, please. I’m so empty.”

His head was spinning with it, the dizzying rush of yang energy so close.

A pinch to his nipples, pinching and pulling, had him cry out– but it did not diminish the need, merely stoked the coals hotter.

“Good,” Tobirama praised, low and close to his ear. Kakashi opened eyes he hadn’t recognized closing, then closed them again tightly. Tobirama allowed it. His laughter swept over Kakashi’s jaw, lips and the hint of teeth pressing down, down, down his throat.

He bit sharply at the junction of neck and shoulder and Kakashi moaned for it, knees coming together to squeeze the man between them tightly. A puff of amused air at his wettened skin, and then Tobirama moved lower. Kakashi had a bare moment of panic before the man’s devouring mouth reached his tit, and another wave of thought-obliterating pleasure rocked through him.

Tobirama hummed into his skin, sucking softly. One hand went to the neglected breast, the other sliding to his shorts. Heat blossomed, literal fire instead of the loin variety Kakashi knew and loved. The cultivator summoned white fire; in moments, his shorts were ash.

He kept his hands above his head, squirming into Tobirama’s mouth, wishing nothing more than to hold his head there, to tangle his fingers in his hair, find out if it was as soft as it looked.

Tobirama’s hips left his, leaving instant coldness in his wake– Kakashi was bereft–

“No! ” He snarled, struggling and forcing Tobirama to hold him down once more. A single hand held both his wrists before he could get more than an inch or two off the ground.

“Down!” Tobirama ordered right back, teeth bared, and Kakashi– miserably– did. “Insolent brat. Look.”

But of course Kakashi couldn’t, of course he–

Tobirama released his wrists with a pointed squeeze and took Kakashi’s chin instead, and Kakashi found he could see between them, see Tobirama’s– bare– cock held in his free hand, see the moment the dripping head nudged against his.

“Oh.” Kakashi swept his tongue over his lips, breathless. “Oh, yes, please.”

Tobirama made a derisive noise. Kakashi barely heard it. The man let his cock rest against Kakashi’s, sitting cutely above his mound. They were so different, making a startling pretty image.

Tobirama was well over three times his size, but no more monstrous than any human. It was Kakashi who was small here, a finger’s length at best– and half of that, the soft, round head.

Tobirama released his own cock to thumb it, sending lightning jerking up Kakashi’s spine.

“Do all male succubi have such?” Tobirama tipped his cock this way and that, studying it. Studying him. The master of the peak of knowledge, of forbidden cultivation and terrifying, innovative seals. The thrill of it was erotic as fuck.

(Kakashi knew more than one demon who would swallow their pride and run in fear to see Tobirama across a battlefield, much less be held in this way. It was a literal nightmare to most demons. The King of the North wouldn’t cross him for love or money.)

A small squeeze reminded him of the question, though it also made his next breath a gasp.

Mutely, Kakashi nodded. More or less.

Tobirama’s eyes narrowed. He visibly decided to put away the question for later, where he might take a more thorough answer. The promise of a ‘later’ stole Kakashi’s breath, but his eyes were fixed on their joining. Of the steadily leaking pearl liquid that tipped the cultivator’s cock.

He wanted to taste it. He wanted it in him, stretching him, forever.

“Is this what you need?”

Blunt, promising pressure against his opening. Kakashi’s eyes widened. He swallowed hard, nodded. Sound was abruptly impossible around his tight throat.

Tobirama stroked his thick cock teasingly, the bridge of his knuckles brushing Kakashi’s vulva on the upstroke. With just the slightest push of his hips—

If he would just move—he’d be sheathed inside. It was all Kakashi could think about. The precoma Tobirama had already produced smeared against him, hot with yang energy.

Kakashi bit his lip. He was unraveling.

Tobirama made an interested noise, consideration like Kakashi was a specimen under a microscope to him, and it shouldn’t have made him hotter but it did.

Then, his big hand slid under Kakashi’s back, lifting his hips up just so, and he eased forward.

Kakashi’s mouth dropped open. His head fell back and he whined. Tobirama’s fingers rubbed at the base of his spine as the head pushed through his folds, dipping in a scant millimeter before pulling back.

Every muscle in Kakashi’s body clenched tight in anticipation. Tobirama hummed under his breath. Before Kakashi could complain, he shifted his hips and fed him his cock.

First the head and then several inches in one long, continuous glide. It pressed him open; he was so wet it didn’t even burn and Kakashi almost mourned the fact, intoxicated by pleasure.

Nerves lit all along his pussy. Yang energy rushed into him, sucking greedily into where he was emptiest, and Tobirama huffed in surprise.

“Take it,” He said, voice filled with easy command. This was a man used to being obeyed and Kakashi would not dream of denying him. He drank greedily, the sensation of cock filling him up almost secondary to the golden energy, masculine and robust.

Kakashi moaned, tensing up and rocking into it. Beneath him, his wings sprung out of his back, black and resplendent.

“I thought so,” Tobirama hummed, settling into a rhythm of push and pull. Each tiny stroke brought a rush of energy, filling Kakashi up in waves, stealing his breath. “The texts say your kind has extra appendages. Let’s see…”

“More!” Kakashi insisted, voice breaking halfway through, and Tobirama obligingly pushed deeper into him. He still wasn’t bottoming out, which was just hateful of him, but Kakashi couldn’t complain. Every time he tried the waves of qi pulled him under, dragging him closer to the edge.

His cock throbbed, steadily leaking precome onto them, making the slide even wetter, even stickier.

Tobirama brought energy into his fingers, pressing just so, and Kakashi’s tail slipped right out into his hands. The black appendage was so sensitive, the nerves raw from being unexposed for so long, and Tobirama stroked the base like a cock just as he finally—finally—gave Kakashi all of him.

Kakashi came all over himself with a startled cry, cock pulsing over and over again. The come fell straight down, coating the white hair around Tobirama’s shaft; coating the cock itself and all of Kakashi’s vulva.

His pussy glistened with it, some of it even pushing inside him with Tobirama’s slow, mean grind. He kept himself fully pressed into Kakashi for the duration of his orgasm, refusing to pull out, and Kakashi could marry the man.

He hadn’t even got his breath back when the cultivator pulled back an inch and thrust hard back inside. Kakashi cried out, voice hoarse, legs falling open limply on either side of him.

“Did you think we were done, succubus?” Tobirama asked, squeezing his tail. Kakashi’s whole body shuddered, covered in come and sweat.

Tobirama eased his hips back casually, thrusting forward with the slick sound of skin on skin. He pulled one of Kakashi’s legs up to his hip for better access, keeping the rhythm slow and maddening.

“You were hungry enough to come here, desperate enough to risk my attention.” He said, voice low and gravelly with his own pleasure. “Well, congratulations. You’ve earned it. When I’m through with you, you’ll never know hunger again.”

It sounded like a promise. And spread out on his back, stuffed full of brilliant golden energy and the best cock he’d ever had– Kakashi believed every word.
