Work Text:
A loud noise shakes the room, jolting Atsumu awake. After a brief moment of confusion, he rolls over and closes his eyes. While Osamu won’t admit it, he still falls off his bunk at least once a month. New day, same bullshit.
It takes Atsumu a long moment to remember that Osamu left for Tokyo yesterday evening.
Heart leaping into his throat, Atsumu sits up straight like a man possessed then instantly crumples back onto his mattress, his head ringing with pain. Fuck the top bunk, why'd he ever pick the top bunk—
He manages to scrape together the last vestiges of his consciousness to glance over the edge of the mattress. “How are you and who did you get into my room?” he asks, seeing a figure—or three, nope, five—across the room near his desk.
“Huh?” a voice squawks. “You’re the one who summoned me?”
Atsumu’s eyes narrow in thought before everything clicks into place. Yes, he had drawn a pentagram and tried to summon a demon to curse Osamu for the bullshit he pulled yesterday, but he didn’t think that it’d actually do anything. “Can nothing be done for the LOLZ these days?” he laments. “No gags? No committing to the bit?”
“I don’t think you’re speaking Japanese,” the demon says, “but I’m here now, and you’re the one who did it.”
Atsumu flops back to the bed, half-convinced that this is a dream. “Reddit isn’t supposed to be a reliable source, the fuck…”
“Reddit is Hell’s most cited website, actually” the demon says.
“Of course it is.”
“How did you even manage to summon me?” he mutters. “I just started today. I was literally in the middle of orientation.”
Atsumu pops back up straight (slowly) and squints, finally focusing enough to take in the scene in front of him. The demon is standing atop the pentagram, dressed in the business-casual standard: a white button up, pressed slacks, and smart shoes. His hair is a ginger bird’s nest, bright and charming. The only features that distinguish him from humans are the little, red horns atop his skull and the sleek, black tail whipping impatiently behind his back.
“Orientation?” Atsumu asks, a beat late. “Isn’t Hell all about, like, chaos and shit?”
“Boredom and chaos are opposite sides of the same coin. In the end, both’ll drive you crazy.”
Atsumu nods dumbly while somewhere in the back of his head acknowledges the irony of being enlightened by a demon. “Well, how do I send you back?”
The demon’s tail flicks erratically. “I don’t know—I was supposed to learn that today at orientation.”
“Fuckin’ hell,” Atsumu says. Resigned to the fact that this is going to be something he actually has to deal with, he climbs down the ladder to his bunk. It’s only when he gets to the bottom and sees the demon’s expression that he remembers that he’s in his kitsune kigurumi. Osamu had gotten it for him as a gag gift a few years back, but when it’s fucking cold, what else is Atsumu supposed to do? Purchase long-johns like a hag?
The crushing weight of humiliation settles on Atsumu's shoulders. “Eat me, please,” he begs the demon. “No one was ever supposedda see me in this. Just kill me now.”
The demon snickers, hand coming over his mouth. “Nooo, but it’s cute!”
“Eat me, demon!” Atsumu shouts. “What else are you good for?”
“Firstly, my name's Shouyou. Secondly, demons only eat souls, and that’s not even my speciality.”
Atsumu's curiosity momentarily overrides his death wish. “What kind are ya then?”
Shouyou smirks before a cloud of dust forms out of nowhere, shrouding his body. When it dissipates, he’s still standing there, but his business-casual clothes have dissolved along with it. Atsumu’s jaw drops.
Don’t be horny for a demon, don’t be horny for a demon, don’t be horny for a demon, Atsumu thinks, but it’s hard when Shouyou looks like that: a beefy mass of toned shoulders, defined abs, and whipcord legs. The giant cock laying limp against his thigh certainly doesn’t help.
“I’m a succubus. So I guess I could eat you—out, that is.”
Atsumu—and he’ll take this to his grave—squeaks like a deflating balloon.
Shouyou sniffs the air, his smirk widening. “Are you a virgin, Atsumu-san?”
“How d'ya know my name?”
“You summoned me. It’s in the contract.” Shouyou waves a hand and a piece of paper appears, pointing to the bolded header: Miya Atsumu, 18, Hyogo, Japan. The rest of the page is in 5-point font, with words sprinkled in like liability, jurisdiction, and indemnity.
Orientation, now paperwork. Hell sounds worse than Atsumu originally thought.
The paper disappears before Atsumu can develop a headache from trying to read further. “Are you a virgin, Atsumu-san?” Shouyou asks again, suddenly three steps closer.
Atsumu backs up reflexively, the back of his head thunking against the bed frame. “Uh. Does a handjob in the locker room count?”
Shouyou laughs, not unkindly. “It’s something. But you’ve never been stretched open? Had a cock buried so deep in your ass, you couldn’t breathe?” Atsumu’s hole clenches down on nothing at the suggestion, his hands curling into fists at his sides.
Shouyou hums, leaning in closer. “Or maybe you’d prefer to do the fucking.”
It feels like a slap in the face, and Atsumu's cheeks burst accordingly into flame. “I…”
“Nothing has to happen if you don’t want it to—I’m a demon, not a monster,” Shouyou says, his gaze dropping to Atsumu’s crotch. “But something tells me you’re not entirely opposed.”
Atsumu’s cock jumps at the attention. He's always been the type to try something at least once. What’s the worst that could happen from losing your virginity to a succubus? (“Twelve million fucking things, you fucking scrub!” Osamu’s voice shouts at the back of his head. Atsumu mentally plugs his ears.)
He still hasn’t answered when Shouyou reaches up, hands moving to his shoulders. He pushes him down to sit on Osamu’s bed and then climbs into his lap. “How about something down the middle, hmm?”
Shouyou grinds his hips forward, the heat running right up Atsumu’s spine. Atsumu’s lips fall open as Shouyou continues, hands sliding up his neck. Shouyou’s fingers find his hair, and Atsumu’s breath catches when his nails drag against his scalp.
Atsumu uses the last of his clarity to unzip his kigurum; Shouyou crawls off Atsumu’s lap so that he can kick it off his feet. He only has a moment to miss the heat when Shouyou lifts him up by the armpits and hauls him further up on the bed. Shouyou straddles him again to wrap a hand around their cocks, and Atsumu pants out, “Fucking Christ—aah, oh God—"
“Figured I’d start with something familiar,” Shouyou says, a sly twist to his lips.
Chiyo-chan’s delicate and inexperienced fist felt nothing like Shouyou’s, which grips Atsumu like he owns him. The hot slide of another cock against his only heightens the intensity of it all, the slap of skin on skin silky and sinful. Shouyou’s free hand wanders across Atsumu's torso, glides over his abs up to his chest. His fingers dig into Atsumu’s pec, kneading it like a curious kitten.
“You’ve got quite the body, Atsumu-san,” Shouyou comments.
“Thanks, I work out—ooh—” Shouyou pinches his nipple, just on the side of painful. Atsumu’s head spins as a rush of blood shoots south, his cock jumping in Shouyou’s grip.
“Oh, you liked that?” Shouyou asks, then does it again, harder this time. Atsumu yells, back arching off the bed. A wave of hot pleasure floods his body, a sheen of sweat breaking across his brow.
“Stopstopstop—” Atsumu says, but Shouyou isn’t listening, rolling his fingers this time. “Mmmgh’mgonnacome, fuck, shit—”
Just as Atsumu feels himself tip over, something wraps around the base of his cock and squeezes like a vise. He cries out as he’s yanked from the edge, flung back to earth with a painful thud.
Shouyou’s hands keep moving, one toying with his chest as the other strokes the heads of their cocks. But the restricting pressure doesn’t let up, and Atsumu points his swimming vision downwards.
Shouyou’s tail is coiled around the base of his dick like a snake, the spade-shaped tip waving at him teasingly. Atsumu feels his arousal spike, biting down on his lip to temper an embarrassing groan.
Shouyou reaches up to coax Atsumu’s lip out from between his teeth. “Don’t hold back, Atsumu-san. I wanna hear you.”
Atsumu sucks in a breath and nods sharply. His eyes dart down to Shouyou’s finger before snapping up to meet his gaze, and Shouyou’s expression shifts into something more mischievous. He thumbs over Atsumu’s lip, syrupy slow, and Atsumu’s jaw relaxes, bemused yet expectant.
Shouyou’s eyes light up with delight. “For someone so inexperienced, there’s a lot that you seem to like." He pushes in and pets down Atsumu's tongue. Atsumu shivers, his lips involuntarily wrapping around his thumb; when he sucks lightly, Shouyou lets out a pleased hum.
"I wish I'd known you'd look like this, taking my fingers," he muses. "It would have been real fun to watch you blow me."
Atsumu pictures it: on his knees, with Shouyou grabbing his hair and sloppily fucking into his mouth. The way his cock, so thick and hot, would feel on his tongue. Atsumu whines, sucking harder.
"Another time, maybe," Shouyou says, pulling out of his mouth. Atsumu hadn't even thought about that—the possibility that the first time doesn't have to be their last. He could have Shouyou in his bed, again and again. His mouth waters at all the possibilities, saliva pooling under his tongue.
He swallows sharply when Shouyou flicks his nipple. "Don't get too up in your head, Atsumu-san. We've got a ways to go." He reaches back, guiding Atsumu's hand to his ass. Atsumu stops to squeeze it, appreciating the soft skin covering firm muscle. Shouyou gives their cocks an appreciative stroke, but continues shifting Atsumu's hand further until his fingers brush against Shouyou's hole.
"I feel the need to say that normally you need lube for this," Shouyou says, "but since I'm a succubus, tonight you don't."
"A demon lecturing me about safe sex," Atsumu mumbles, still mesmerized by Shouyou's entrance fluttering under his fingertips. "This is not how I thought my Friday night'd be going."
He slips a finger in as Shouyou chuckles. "No, I'm sure it's even better," he says cheekily.
Atsumu thinks about the orgasm he gave himself just hours ago, watching B-tier porn and coming in five minutes. "You got no idea."
Shouyou practically purrs at that, sinking down lower onto Atsumu's finger. "You can add another," he says, and Atsumu doesn't have to be told twice. The second is a bit tighter to fit, but Shouyou takes it like a dream, lips parting as his lashes flutter.
"God, your fingers are so thick, it feels so good," Shouyou says. "Okay, now pull back a little. More. More… Mmm, right there. Now curl them towards you."
Shouyou moans obscenely, planting both of his hands on Atsumu's chest. He barely registers the loss of stimulation on his cock, so fixated on Shouyou's blissed out face.
"Again," Shouyou sighs out, and Atsumu does as he's asked. Shouyou's back arches, his cock dribbling precome all over Atsumu's stomach.
"Jesus Christ," Atsumu breathes.
"I prefer Satan—nnghhh—"
Atsumu would laugh but it feels like all the breath has been sucked out from his lungs. Always a fast learner, he squeezes in another finger and returns to Shouyou's prostate, stretching him deeper. Shouyou's entire body quivers, including his tail at Atsumu's base.
"Okay, I'm ready," Shouyou says eventually. When Atsumu pulls out, Shouyou winds his tail higher around Atsumu's cock, lines up, and sinks down. Despite his thorough work, Shouyou's still devastatingly tight. He makes a slow and steady descent, and by the time he's seated, Atsumu's panting like a dog in rut.
"Mmm," Shouyou hums, clearly pleased. He grinds his hips in a slow circle before clenching down. Atsumu grits his teeth, back on the knife's edge in seconds despite Shouyou's improvised cockring. "I'm gonna start moving."
"And I'm gonna die," Atsumu says, still trying to adjust to the crushing heat.
Shouyou hikes himself up before sinking right back down, setting up a quick, rough rhythm. Atsumu grips his thighs like a lifeline, though the flexing muscle and sweaty skin aren't doing much to help him stay sane. As if in a trance, one hand sneaks up to wrap around Shouyou's dick, rapt by the lewd squelch of every pass.
Shouyou's eyes have shut, his head thrown back as he bounces on Atsumu's cock like his life depends on it. Little noises leave his lungs with each breath, and Atsumu's eyes catch on his parted lips, enraptured. He watches them shape around his name, around moans and whines and whimpers.
Atsumu licks his own lips, a suggestion on the tip of his tongue. "This seems a bit backwards to ask," he says, "but is kissing on the table?"
Shouyou pauses for just a moment to give Atsumu an are you kidding me? look before leaning forward. Atsumu makes a noise as electricity crackles across his skin, the hot, wet slide of Shouyou's lips instantly overwhelming. Shouyou sneaks a hand into his hair and tugs him closer, until Atsumu can't tell where his body ends and Shouyou's begins.
When Atsumu moans, Shouyou uses the opportunity to lick into his mouth. Atsumu's eyes roll back as he swallows the heat, stoking the fire in his belly.
After stroking over his teeth, Shouyou pulls out to nibble on his lip, and Atsumu sucks in a deep, centering breath before his hand speeds up on his cock. Shouyou keens as he clenches down.
Head spinning, Atsumu dips into Shouyou's mouth, ready to explore himself. Before he can get far, Shouyou sucks on his tongue, slick and merciless. His grip tightens in Atsumu's hair, tilting his head back to deepen the kiss, and Atsumu's vision goes white.
His cock throbs as it shoots deep inside of Shouyou. Shouyou's lips move against his as he pulls out to the tip, clenching rhythmically with freakish precision. Atsumu breaks away from the kiss, unable to do much more than pant against Shouyou's lips as he comes and comes, his balls so tight it aches.
After an eternity, Atsumu feels the last bit shoot out of him, and his muscles relax, body sinking into the mattress. Shouyou continues grinding in slow circles until Atsumu's whimpering from overstimulation and then some.
"You sound so good like this," Shouyou purrs, and Atsumu shivers.
Shouyou eventually takes mercy by pulling off of him, flipping them onto their sides, and kissing him again. He plays with Atsumu's hair, scratches at his scalp, and Atsumu melts into his touch, his limbs like jelly. He wants to fully enjoy it, but something niggles at the back of his mind, reminding him that his job isn't done yet.
With great effort, Atsumu manages to wrap a hand around Shouyou's cock. Shouyou gasps and pulls back to say, "Oh, no, you don't have to do that—"
Atsumu shuts him up with a kiss. "I wanna, though," he says, eyes cracking open. "Can I?"
Shouyou hesitates before nodding. Atsumu smiles into their next kiss, hand pumping slowly over Shouyou's cock. He plays with his tempo and strength, observing what makes Shouyou's breath catch and stutter. This close, Atsumu can clock other smaller tells, like the shift of his chest or the flutter of his lashes. Shouyou's hand falls from his hair to cup his cheek, his palm solid and warm.
The wildfire passion of earlier has dispersed, yet Atsumu still feels like he's burning alive.
With a flick of his wrist, Shouyou spills onto his fist, making a high, pleased sound in the back of his throat. Atsumu swallows it down greedily, coaxing more out of him while he still can. The noises devolve from pleasure to pain soon enough, and Atsumu hesitates just a beat longer than he should before letting go of Shouyou's cock.
Shouyou pulls back from the kiss but stays close, his breath heavy against Atsumu's lips. Atsumu stiffens, unsure of how to proceed. When he and Chiyo-chan finished up in the locker room, he just left. He's in his own room now, though he supposes he should get up and wash the jizz out of Osamu's sheets.
Instead, his hand snakes its way into Shouyou's hair, combing over the locks the same way Shouyou did to him. Shouyou hums, throwing an arm around Atsumu's waist and pulling him closer. He's so warm—Atsumu can't tell if he's touch starved or if demons run hotter. His fingers scratch at the base of Shouyou's horns, and Shouyou's lips curl into a smile, his tail flicking lazily back and forth.
"For your first time," Shouyou says, "you sure know how to treat a guy right."
Atsumu can't embarrass himself by saying what's on his mind—I like how you feel against me—so he replies, "Never know when a demon'll show up randomly in my dorm again. Carpe diem, or whatever. You speak Latin? Seems like a Hell thing."
Shouyou shakes his head. "Only Japanese, Portuguese, and English."
"Only," Atsumu scoffs.
Before Shouyou can respond, a poof sounds by their ears. Atsumu turns his head to squint upwards, then closes his eyes with a groan. "Not the contract…"
Shouyou reaches up to grab it, pausing for a long moment. "Oh, it's a Section 103b. Sign it confirming I completed my duties, and I'll be able to go back to Hell."
"Hmm, sus."
"You can read it if you want."
"Hell no. Gimme a pen." One materializes in his hand, and Atsumu signs the dotted line. "So what's the catch? Are we bonded together for life? Are you draggin' me to Hell to become your sex slave?"
Shouyou waggles his eyebrows. "I mean, if that's what you want, I've got no complaints."
"Let me at least get recruited onto a professional team first. I can pull a Persephone: 6 months on Earth playin' volleyball, 6 months in Hell fuckin' you senseless."
"Deal," Shouyou says, hand gliding over the curve of Atsumu's ass before squeezing. "But no, I promise it was just to let me back into Hell. It's late here, isn't it? I should let you get some rest."
Atsumu wants to resist, but he does have morning practice tomorrow, and it's not like he can keep Shouyou here forever. His hand falls from Shouyou's head. "Well. Thanks for the fun."
Shouyou snaps his fingers, and the feeling of sticky, cooling come on Atsumu's stomach and cock disappears. A soft warmth envelops him too—his kigurumi. "Thanks for indulging me," Shouyou says."Learning about the existence of Hell and demons and losing your virginity all in one night was probably a lot to you."
Atsumu stretches his arms over his head like a cat. "A bit of an understatement, but I'm glad I did."
Shouyou leans forward and kisses him, chaste and sweet. "You know how to summon me now; feel free to again. Ah, shoot, I gotta get back to Orientation!" He springs up, snaps back on his clothes, and scurries to stand over the pentagram. "Bye, Atsumu-san!"
Atsumu barely has time to bid him farewell before Shouyou disappears into a puff of smoke.
After staring at the space Shouyou left behind, Atsumu rolls onto his stomach and buries his face into Osamu's pillow. He can still catch whiffs of Shouyou's charcoal and cinnamon if he inhales deep enough.
He should really climb back up to his bunk, but Shouyou's demon magic cleaned up all the jizz, and he's so cozy. Instead, he musters up the last of his energy to crawl under Osamu's covers, then tugs at his charger cord until his phone falls to the bottom bunk. Opening his browser history, Atsumu finds the Reddit page and screenshots it.
No way in (or out of, actually?) Hell he's risking losing that shit.
