Work Text:
Rin knows that Sae looks down on him because he’s an alpha. Even if Rin takes his suppressants like clockwork and fights his way through his weak heats as quickly as possible, he will always be at a biological disadvantage to his Alpha older brother. Thousands of years ago the human race decided it could get ahead by making certain members as attractive as possible while they were fertile. It worked, but now that biological framework could wreck Rin’s life at any moment.
For example, this one, slumped over on one of the benches outside the Bluelock baths, hand fisted in his jersey and pressed against his chest to try and still his racing heart.
Rin had stayed on the field late after regular practice had ended, doing drills over and over while he waited for the usual end of day rush to clear the showers. He knew his heat was starting, and he didn’t want anyone else getting so much as a whiff of him. He figured all he had to do was put in some extra hours, shower off the reek of his own pheromones, log his heat day with Ego, and go to bed. Maybe his libido would force him to use one of the knotting dildos which came from dispensers unpleasantly similar to those used in the dining hall. Rin almost never jerked off during his heats. He would just stick a dildo inside of himself and deploy the knotting mechanism to pacify his empty hole.
“Rin? Are you alright?”
Rin stands automatically. His head swims, and black dots float in front of his eyes. “I’m fine.” Another second on his feet and he’s stable enough to turn and look at whoever approached him.
Isagi is standing a few lockers away. His gaze hovers around Rin’s knees, just where rin can feel wetness on the backs of his thighs. Given the way Isagi is looking at him, Rin is fairly certain he’s soaked through his shorts. He regrets removing his undersuit before he ran drills, even if he was feeling hot.
Rin resists the urge to bury his head in his hands. The doctors who examined him before Bluelock started warned him that suddenly sharing tight quarters with so many healthy, unrelated Alphas might trigger more intense heats. But it was the same disclaimer he had heard before he went on an overnight trip with the rest of his middle-school class. Nothing had happened back then. He hadn’t expected this to be different.
“Do you need some help?” Isagi asks. His tone is neutral, no prying or condescension. His expression is painfully earnest.
Rin opens his mouth to spit that he doesn’t need help from some pathetic Alpha who can only get an Omega to so much as look at him by cornering them during their heat. He inhales some of Isagi’s scent and his vision goes black.
It should be humiliating to have Isagi catch him and help him to sit on the bench, but Rin is too scared to care. The darkness clears quickly, but Rin keeps his head on Isagi’s shoulder, not trusting what will happen if he raises it.
Rin slowlys realize how close he is to Isagi’s scent gland. It’s small, but the reddish bump on the side of Isagi’s neck, near the lymph node, is clearly visible. Rin’s mouth waters, instincts screaming to nuzzle against it, use his heat to trigger Isagi’s rut.
“No!” Rin says, out loud. He pushes away from Isagi so hard that he falls off the bench and lands on the floor, his ears ringing, tears welling up in his eyes.
Every bit of porn Rin has ever seen flashes through his mind, all those tiny, pliant Omegas mewling Alpha. Alpha, please.
He will not do that.
Isagi hovers over Rin. Unlike him, Isagi has changed out of his uniform and is wearing his sweats. The smell of fabric softener reaches Rin.
That’s the best thing about this place, Rin thinks, dazed, Fresh sweats whenever you want them. They also arrive via dispenser, sometimes in a little cloud of steam. Isagi smells liked that, clean, cozy fabric, warm skin, something plasticky that should be disgusting, but just reminds Rin too keenly of astro-turf and memories that used to be fond.
“I’m going to get a nurse,” Isagi says.
Rin ‘s fist crumples the front of Isagi’s sweatshirt, jerking him down to Rin’s eye level. “It’s just a heat,” he grits out, “I’ll be fine.”
“Then you should go to bed,” Isagi says. He pulls Rin to his feet and says nothing when Rin has to lean on him to walk straight.
They make it to Rin’s room, and Isagi shuffles Rin over to his bed. “Okay Rin.” Neither of them move. “Uh, down time.”
Time to lay down on his cold bed, with its sterile sheets. Time for Isagi to leave, taking his perfect, comforting scent with him. Rin slides down Isagi’s side, sinking to his knees. He buries his face in Isgai’s groin, where the scent is strongest. His sweatpants are soft, the skin underneath warm and tender. After a moment Isagi’s broad palm comes to rest against the back of Rin’s head, gently encouraging him as he nuzzles against Isagi’s thigh.
Rin’s mouth drops open, and a moan drags out of his chest. It sounds like it was pulled from the bottom of his diaphragm.
That snaps him out of it.
Once again, Rin pushes away from Isagi and winds up on the floor, His thighs squelch unpleasantly with his own slick.
“Rin,” Isagi whispers, kneeling so they’re eye level, “I could stay with you if you want. It’ll make your heat easier.”
Rin can do anything the hard way, but his thoughts are so heavy and clouded. It seems foolish to make things more difficult for yourself than they need to be.
“I’m not looking for a mate,” Rin growls. Actually, he isn’t sure if the growl comes through, but the meaning is clear.
“Of course not,” isagi says, because if nothing else he is smart, and he knows Bluelock is no place for that sort of thing. “But Kunigami told me that even having one orgasm with an alpha helps a lot.
Rin would ask what the fuck that loser hero knows about it, if every cell in his body wasn’t screaming in agreement.
“…kay.”
Isagi takes Rin’s hands and helps him onto the bed. Rin pulls his jersey over his head as Isagi works his shorts off his legs. He’s still wearing his cleats and he almost complains, but then Isagi’s own shirt comes off and his scent wafts over Rin. The pounding pressure of his heat eases, and Rin sighs, sinking into the mattress underneath him. Isagi lies on top of Rin, skin to skin, and suddenly Rin can breathe easy for the first time in hours.
Isagi rests his head on Rn’s chest and Rin automatically buries his nose in Isagi’s hair. It’s thick and soft, exactly how it looks. He had wondered about that, after seeing it so often soaked with sweat, or the way the ends float and stick up as it dries again. Isagi is warm, not the aching fever of heat, but warm the way you want your bed to be on a cold night.
Isagi is pressing kisses to Rin’s neck and the side of his jaw, and he’s close enough to the scent gland on the back of Rin’s neck that it might worry him, but it doesn’t. Isagi is smart. Straightforward. Not remotely the sort of person who would mark Rin just because he could.
There’s a word for this sense of knowing. Trust, maybe. Like he trusts Isagi to support him on the field, to pass to him when that is the obvious goal.
Isagi’s hand slides down Rin’s torso, and Rin twitches as Isagi wraps it around Rin’s dick. It’s so little contact, nothing Rin hasn’t done to himself, but the slow drag of Isagi’s hand up and down his length is making his legs tremble, and sending fireworks shooting up his spine.
Rin is rocks up into Isagi’s hand, legs wrapped around Isagi’s hips. His sweats are still on, but Rin can feel Isagi’s dick twitching against his stomach. He wants it inside of him so bad he has to close his mouth tight against the urge to beg.
“Does this feel okay?” Isagi whispers, and Rin lets himself laugh.
“It’s…it’s really good. Maybe…I could do something for you?” Ask to put it in. Please please please ask to put it in.
“No, I’m okay,” Isagi says, before turning his head and nibbling the shell of Rin’s ear. It sends a little shock through Rin, his back automatically arching, as if he needs to get closer to Isagi. As if he could.
“I-I should really do something for you,” Rin says, “It, um, it’ll help.” He doesn’t know that for sure, it just feels right, but somehow he’s surprised when Isagi doesn’t ask any questions.
“Okay,” he says, and peels himself off of Rin, leaving Rin’s dick to leak and twitch against his stomach (nononobadbadbad) so he can pull his sweats and underwear off. Then he’s kneeling between Rin’s thighs, his red, weeping dick filling Rin’s vision (yesyesyesyes).
Rin realizes he’s pushed himself up on his elbows so he can get a better look. Isagi grips Rin’s ankles, then runs his hands up Rin’s legs, and Rin knows the instant his fingers brush past the top of his socks and reach his skin again because his stomach goes hot and liquid, and more of his slick spills onto the sheets.
“Here,” Isagi says, and he takes Rin’s hand and wraps it around both of their cocks. Isagi’s is shorter than Rin’s, but thicker, and so turgid Rin can feel Isagi’s pulse against his hand.
He’s never touched another person’s dick before, prepubescent accidents in the tub with his brother notwithstanding. It’s strange to hear all the air gust out of Isagi’s chest and know it’s because Rin’s hand is on him. Isagi thrusts into Rin’s hand and Rin mimics him. His brain is full of syrup, sweet, and thick, and impossible to fight.
Isagi’s thrusts grow erratic and Rin fumbles. He’s caught between trying to grip them both without hurting either of them, but also trying to focus on the dizzying sensations flooding his own nervous system.
Isagi moves Rin’s hand away and pushes on his shoulders, gently laying him back down. Rin makes a sound of protest, but Isagi says, “It’s okay, Rin. Just let me help, and Rin…Rin trusts Isagi to help him,
Isagi won’t laugh at him later, reminding him he was too cum drunk to even jerk them off properly. He just curls over Rin, his soft, light scent filling Rin’s senses. The drag of his dick against Rin’s is so good every desperate pulse of precum spurting out of Rin feels like a tiny orgasm. T he pleasure is so sharp and sweet it might as well be a stab to the gut with a sharpened candy cane.
Isagi rears back so he can grip Rin’s thighs and focus on his thrusts. Rin watches him. Isagi’s chin is titled up, the long line of his neck leading down to the arch of his back and shoulders. As he moves with easy confidence in his body he looks every inch the alpha.
Rin has no idea his orgasm is so close until his balls tighten and a lightening blot shatters his thoughts. He screams, hips jerking, and suddenly Isagi is holding Rin down. His hand is tight around Rin’s dick, working over him and drawing out the pleasure till Rin feels like every once of tension getting wrung out of him through the tip of his cock.
Rin collapses back onto the bed, breathing heavily. Isagi pulls away, just an inch, but Rin’s heat roars up, blazing over his body, overriding all thoughts other than Isai is leaving, he’s leaving me, I’m not finished, this isn’t over, I can’t breath, I won’t live if he doesn’t knot me.
Rin comes back to himself slightly, his arms tight around Isagi’s back, his face buried in the juncture of his neck and shoulder. “Nonononono,” he’s breathing into Isagi’s skin.
Isagi has gone rigid. “Rin? Are you okay? Did something—”
Rin bites Isagi hard, holding him every way he can. The sound Isagi makes is music in his ears. “You’re staying right here.”
“I don’t…I don’t think that’s a good idea,” Isagi croaks. “I…Rin, if I don’t leave now I’m going to knot you.”
Rin holds Isagi tighter, nails digging deep into his skin.
Isagi bends down a bit so he can press his face into Rin’s neck. “Are you sure, Rin?”
Rin is glad Isagi keeps saying his name. He feels like he is trying to survive a shipwreck, that important part of him Rin barely clinging to a piece of driftwood. Every time he feels stable he’s tossed by another wave, constantly going under before gasping his way to the surface.
Isagi says his name and Rin can keep his head above water. He can orient himself, sure which way he needs to go to reach land. Even if it is very far away.
“Yes," Rin whispers.
“Can you turn over for me?”
Rin tenses, and Isagi swallows. “I’ve never done this before, and I’ve heard it’s easier to-to hurt someone if you’re facing each other.”
As if Rin intends to get off Isagi’s knot a second before it is completely flat. But Rin understands that Isagi’s nervous, and maybe he should be a little nervous, too. It’s just hard when it seems so obvious what they should do next.
Rin lets go of Isagi long enough to turn over, the tips of his cleats scuffing the sheets as he draws his knees up to present.
Isagi rests his hands on Rin’s ass, touch hesitant for a moment before he squeezes hard. Rin growls into the mattress.
“Wow, Rin, you’re so wet,” Isagi says as he presses his fingers against Rin’s hole.
A flush rolls over Rin’s skin at how easily Isagi’s fingers slip inside of him.
Isagi thrusts shallowly with his finger. It isn’t nearly enough stimulation, but worse than that, Rin can feel Isagi pulling on his rim, the gust of his breath on Rin’s bare skin. He’s examining Rin, taking stock of his body and its reactions. It’s a very Isagi thing to do. Exactly what Rin would expect if he’d really thought about this, but it bothers Rin that Isagi is carefully assessing his body and all Rin can do is clutch the sheets in front of him and moan.
Isagi slips another finger into Rin, but instead of thrusting he presses down hard, his thumb rubbing against Rin’s taint. It sends an electric current through Rin, and his leg kicks out behind him, narrowly missing slamming right into Isagi’s chest.
“Hey!” Isagi yelps, scrambling backward.
Rin turns back over. He shouldn’t have his cleats on the bed, but he can’t quite connect that thought to why he shouldn’t do that, so he ignores it. “I don’t like that. We’re not-I won’t let you fuck me like that.”
“Okay,” Isagi says, “How do you want to do it?”
Rin wants to ride Isagi. He wants to make sure he knows what’s happening and can control every second of it. But his legs feel week and shaky like…well, like he did a full practice and extra drills while in heat. Anyway, he’s not sure he could stay steady. Even though he knows Isagi would wrap his arms around him and gently lay him down if his legs gave out, he doesn’t want Isagi to know that his legs might give out.
Rin takes Isagi’s wrist and lays back, pulling Isagi with him. For a moment Isagi hovers over Rin on his elbows. Rin stares into his wide, blue eyes, wondering why he is being granted so little skin to skin contact.
“Rin, can we kiss?”
Isagi’s tone is bizarrely soft and plaintive. As if he thinks Rin might say no, with the tip of Isagi’s dick prodding his hole. As if, if Rin said no, he wouldn’t hesitate to follow his command.
“Sure.”
After that there is no more hesitation. Isagi covers Rin’s mouth with his own, wet and hungry. Rin matches him, catching his rhythm and moaning around their tangled tongues.
Rin gasps as Isagi pushes inside of him. He’s never been stretched like this before. The issue isn’t just the size, but also how unrelenting it is. Rin never thought about it, but when he put his dildos in, he went exactly as fast or slow as he wanted. He would automatically stop, even if only for a second, when the stimulation was too intense.
As gentle as Isagi is being, he can’t know what “too intense” is until he has already reached it. And it is intense, the aching stretch of Rin’s hole, the increasing fullness as Isagi slides deeper inside of him. Their kiss is a mess, more an exchange of wet pants than anything, but it’s good. It’s proof that at least Isagi is as affected by this as Rin is.
Isagi comes to a stop, fully seated inside of Rin. He throws his head back on a moan that turns into a sigh, and then, with a choked gasp, Rin feels Isagi’s knot begin to swell.
“Oh-oh my god!” Isagi squeaks, face flushed with more than sexual fervor. “I’m sorry! It’s never been this fast before!”
As if Rin wouldn’t have gone completely insane if Isagi hadn’t finally knotted him already. As if the steady expansion of Isagi’s knot isn’t increasing the sweet ache in Rin’s gut in the worst-best way.
Rin isn’t sure what to say, so he says what Isagi would. He reaches up to stroke the side of Isagi’s face and says, “It’s okay, Yoichi. It feels good.”
Isagi relaxes and Rin can pull him back into a kiss. The rock against each other until Isagi gasps and shudders, going still for a momen . Rin clenches before he even feels the hot rush of Isagi’s cum. Rin wouldn’t have believed it if you told him, but something about that sensation, the knowledge that Isagi is marking him, making Rin undoubtably his, makes Rin’s hole spasm around Isagi’s knot until his eyes roll back in his head. With a stuttered scream, he cums again.
They lie together until Isagi’s knot shrinks enough to slip out of Rin. The haze of Rin’s heat is lifting. He expects Isagi to pulls away immediately, but he’s busy pressing tiny kisses to the side of Rin’s face. He’s also nuzzling Rin’s neck in a way that is making him pleasantly aware of his scent gland. Not like he needs it to be bitten, just like having your hair brushed makes you very aware of your scalp.
Isagi rises on to his knees and says, “I want to look,” his face still flushed, eyes glassy like he’s the one in heat.
He has been very helpful, so Rin lets Isagi take his ankles and push his legs up until his knees are by his ears. He can’t imagine what he looks like, flushed to the sternum, smears of cum covering his chest, the dark lines of his socks and cleats framing his spent dick and puffy hole, still oozing cum and slick.
Maybe he can imagine it. He’d rather not.
Isagi doesn’t say or do anything more. He lowers Rin’s legs, and begins unlacing his cleats. Rin almost protests, but he decides to see where Isagi is going with this.
Isagi pulls off Rin’s shoes and socks, uses some tissues from a nearby box to clean Rin up as best he can, and then helps Rin under the covers. It’s nothing Rin couldn’t do by himself, but he doesn’t complain. He feels like how he thinks his cleats must feel when he polishes them.
Soft, fuzzy memories, like a blanket fresh from the dryer, rise in Rin’s mind. His mother tousling his hair with a towel, the same one she just used on Sae. The wooshing rush of warm darkness, and then her hands gently patting his face dry.
“You should get some sleep,” Isagi says as he pulls his pajamas back on. There’s a tiny damp spot on his sweatpants, but it will be no trouble for him to swap them for new ones.
Rin remembers his manners. “Thank you,” he says, even though the words are garbled, half asleep with his face pressed into the pillow.
Maybe Isagi tousles his hair. Maybe he just dreams it. Everything smells like fresh laundry and astro-turf.
