It’s too hot…
Sweat sticks his hair to the back of his neck. Shouto brushes it off, but it only settles back into place the moment his hand is back in his pocket. The thin cotton of his pajama pants is too thick, too scratchy and he hates it. He knows he should be back in the cabin with the rest of his classmates, but the scent in there – all those alphas and omegas crammed together – had made him nauseous.
Out here is nicer. Even with the heat lighting flashing off in the distance and the clouds starting to roll in to the south, he can still turn his face to the stars and mutter out their constellations from memory as they guide him. The breeze on his face is cool and smells heavily of fresh pine and petrichor.
Shouto’s stomach cramps, the hardest it has so far, and he nearly doubles over. A soft whine escapes him as he grabs the nearest tree for support. He tells himself that this can’t be a heat. That the suppressants his father had put him on were the best, the strongest, and that this must be something else, but deep down he knows. He can feel the wetness leaking down his thighs and sticking his underwear to his skin. Resigned, he turns to head back towards the cabins.
He’ll wake Shouta; probably be sent home or at the very least, be sequestered from the rest of his classmates. He’ll miss out on the vital training being offered here, but he’ll catch up somehow – maybe Izuku will take good notes for him…
Snap
Shouto turns around at the sound, ready to use his quirk to defend himself from whatever wild animal had stumbled upon him, but he finds the woods behind him eerily still. Fireflies blink in the darkness, but nothing else moves. Probably just a deer. He sighs out loud and lowers his hands. No reason to be so edge. It takes him a moment to move though, eyes surveying the area for any signs of life. As he turns back towards the campground, pain lances through his skull and then the world around him goes dim.
When Shouto wakes he finds himself bound, hands behind his back and palms pressed to his elbows. The pain in his shoulders tells him that he’s been like this for some time and that makes him start to panic. His heart is racing as he twists, trying to free himself of his bonds and that’s when the scent hits him. The soft sheets beneath him are laced with it; an alpha, strong, smoky like burnt oak and earthy. He noses against it without thinking and it calms him, making his eyes flutter before he gets himself back under control.
He takes a deep breath and closes his eyes. He focuses on his fire side, guiding heat into his hand and sets off his quirk… only to find that nothing happens.
“Yeah,” A voice comes teasingly from the doorway. “Funny thing about that…”
He watches as a tall man with dark hair and a scarred face steps into the room. He leans over Shouto’s prone form and grins. Staples stand out stark against his skin and that feral smile of his seems to pull the skin on his cheeks tight.
“Quirk-cancelling cuffs.”
Shouto’s eyes narrow on the unfamiliar man above him. “Let me go.”
“I mean, I went through all this trouble to get you.” Touya chuckles. “I’m not gonna just let you go. That’d be incredibly stupid.”
Shouto kicks out only to be dodged, and gets his foot grabbed for his trouble. Touya isn’t bothered by it. In fact, he’d quite expected a bit more fight.
“Don’t be like that, Shouto.”
Heat lances through his ankle from the man’s tight grip and he whimpers without thinking. “How do you know my name?”
“Can’t believe the old man didn’t stud you.” This might have been even more fun if he had. Touya releases his grip on Shouto’s leg to put that hand to his chest and bow theatrically. “Dabi, by the way… for now, at least.”
Shouto reels back and then kicks again, foot landing squarely against a chest, but the alpha barely teeters from the impact. Unfazed, Touya crawls onto the bed between Shouto’s legs and sniffs at the sweet scent wafting off his little brother. That explains it, he thinks as he pulls a knife from his back pocket. One leg is straddled; the other held down.
Fear is beginning to permeate Shouto’s scent. He prepares for pain, heart racing and body tensing, but none comes. Instead, he feels the relief of cool air against his skin. A small sigh escapes him before he catches himself and begins struggling anew. It doesn’t do him any good. His shirt is shredded and then his pajama bottoms.
“My friends will–” Shouto’s voice trails off when cold steel slips against his navel and begins to trail downward, shredding his underwear and grazing over his small, swollen mound.
“Find you?” Touya eyes that dripping pussy, so slick… Untouched – their father never would have let anyone touch his precious masterpiece. “It’ll be morning before anyone even comes looking for you.”
Hands slide up slender hips and grip them tightly as he crawls between Shouto’s legs. Much to his chagrin, they open for him. He must be much farther into his heat than I thought. Not that Touya was complaining. This was quite a pleasant surprise, actually.
“And by then…” He huffs out a small laugh as he grabs peppermint-colored hair and tilts his little brother’s head back. A warm tongue laps just once over the swollen, leaking gland at Shouto’s neck and Touya hums at the taste. “By then, you’ll be begging for me to put my pups in you.”
It isn’t until that moment, until the threat is laid bare for him, that Shouto fully realizes what’s going to happen. His eyes go wide as lips find his skin again and teeth graze over that tender spot. He tells his body to struggle, to use what strength he has left to fight back, but his mind is already starting to grow hazy. Touya’s scent is thick, and so strong… Shouto wets his lips without thinking, a small mewl escaping him as those strong, rough hands begin to move over his body. A thumb grazes over his cocklet making his hips jump, body arching until one nipple meets waiting teeth.
His legs are already spreading wider, slick wetting the bed beneath him. He’s so desperate and he hates that he can’t seem to control it. Was this what it was like? How it would be whenever a heat broke through his suppressants? Could he really do this? Continue to be a hero knowing others could do this to him?
“Stop… please…” Shouto whines, frustrated tears spilling down his face, but he doesn’t even know if he really means it. Those fingers dip inside him, spreading him wide and Shouto finds himself biting off a whorish moan.
“Stop?” Touya lays over Shouto, pressing the warmth and weight of his body down on the little omega and making him even more docile. “Oh no, Shouto… You don’t really want me to do that, do you?”
That smoky scent invades his nose and something in the back of Shouto’s mind sparks – some memory he can’t quite put his finger on – but suddenly this alpha, Dabi, doesn’t seem so bad. What little resolve he’d been holding onto drifts farther away as that thick cock sinks inside him. It hurts, but he feels so full. So good. Like this is what he was meant for.
Touya isn’t gentle. He fucks Shouto hard, snapping his hips forward and burying his cock to the hilt over and over again. Fingers grip Shouto bruisingly as teeth mark over pale skin. His chest, neck, and shoulders will tell the world who this little whore belongs to – if Touya even lets him go when they’re done.
Shouto isn’t sure he wants to be let go. Every fiber of his body is responding to the alpha’s touch. He’s begging, but he’s not sure for what – for Dabi to stop? To be knotted? Those little wet pleas, garbled and bitten off by sobs hardly sound like him, but he can’t bring himself to care. Not when those cerulean eyes are staring down at him expectantly.
“I’m going to ruin you for him.” Touya moans at the tight heat squeezing around him. His knot is already starting to get heavy and full and the desire to unload in that pretty little cunt is overwhelming. “Gonna ruin you for anyone else.”
His eyes are hazy, higher brain pushed back as his instincts take over. This alpha, this stranger, is familiar. Safe and strong, his brain supplies, and he tilts his neck, urging Touya to take what he wants. Shouto nods, neck tilting and exposing himself. “Please, alpha…”
“Fuck…” Touya moans. Shouto looks so sweet beneath him, fucked out and begging, and his eyes wet with tears. “Gonna make you mine, Shouto. Just like you always should have been.”
He kisses Shouto deep, tasting the sweetness of his brother’s desperation before nosing down a sweat-slicked neck so he can suck on a scent gland. His teeth ache to descend and this time, unlike when they were younger, Touya doesn’t stop himself. He bites down hard, teeth sinking into soft flesh until he tastes iron and sweet oil flooding over his tongue. His venom spreads, making the already compliant omega little more than a puddle for him.
That warm, velvety cunt spasms around him at the bite, and Touya fucks in deep one last time, forcing his knot into that warm wetness, locking them together as he unloads his release deep into his little brother’s womb. Shouto mewls, needy beneath him, strong legs wrapping around him as if he would even try and leave. Touya grins devilishly before pulling back to lap at the wound on Shouto’s neck. He kisses the mark he’d made sweetly, the hand in Shouto’s hair softening to an almost gentle touch as he guides plush lips down to the gland on his own neck.
“There’s my good little omega.”
It’s all the encouragement Shouto needs. Small fangs descend and he claims this alpha as his. He lays there in bliss, mind floating until that heat begins to fade. When it does, and his higher brain starts to come back to him, Shouto begins to cry. Could he ever go back to Yuuei? Does he even want to? The alpha’s taste still lingers on his tongue and now that his thoughts aren’t so hazy, he can place it.
“Touya?” Shouto sniffles, eyes glancing up hesitantly into those old, familiar cerulean orbs. How had he not recognized them before?
Touya smiles at the sound of his name. “You always belonged to me, Shou. Always”
He leans down to kiss his omega and finds Shouto willing enough. It’s a risk, but he cuts the ties binding his brother’s arms and is rewarded when they wrap around him and hold him close.
“I thought you were dead.”
“Dad tried to take you away from me, but you’re mine.” Touya rocks his cock in deeper, hands encouraging Shouto to nose against his neck. “And I’m not ever losing you again.”
