Dabi had his calloused hands around Shouto’s throat, masterfully gripping the two veins on each side of his neck. The previous bloodshed and current tension applied from his brother had him lightheaded, the rush of adrenaline suddenly making its way past the center of his body and down south. He wasn’t conscious enough to try to stop the excitement building in his gut but some distant sober part of his brain was screaming against it. Somehow, that only made him crave his brother’s touch even more.
“T-Touya-nii….”, Shouto managed to weakly croak out, in an attempt to.. what? Verbally fight back? It was downright pathetic. He knew he could barely move any of his limbs and Dabi had him pinned down, the weight of the older sibling rendering him completely immobile in this state. Shouto had more or less resigned his meek attempts at trying to fight this, whatever it was.
At that moment, Dabi’s eyes scanned the frail boy beneath him. A pitiful sight. But a beautiful and delicate one. His poor baby brother, at the end of his rope, yet still so filled with resolve. Yes, he absently noted, their father had done an excellent job at breaking and molding his doll. He could see why he was daddy’s favorite. Dabi strengthened the grip he had on Shouto’s throat and smiled down at him, mockingly. He could barely contain himself, but he was patient. He wanted to savour every second of this, to see how this perfect little puppet would fare against what he had in mind.
Shouto, it seemed, was already ahead of him, as Dabi’s eyes scanned even lower and noticed the tent forming in his brother’s hero suit. Huh. Interesting. Maybe his baby brother was already this fucked in the head. He wasted no time and reached his stitched up hand to palm his brother’s dick through the fabric.
Shouto looked up at him hazily through thick eyelashes, clamped together with sticky tears that formed while he was asphyxiated. He immediately sucked in an unstable breath through his teeth, or atleast tried to, as the hand situated on his neck loosened lightly but still enough to constrict his breathing.
“Well…would you look at that,” Dabi rasped quietly into the small space separating him from his brother’s face, “seems someone is excited. Bet you think about your brother fucking you often, don’t you? I wouldn’t be surprised. You’re a sick little shit, Shou. Getting off to your family.” He snickered, picking up the pace of stroking Shouto through his pants, feeling him grow harder. Dabi felt his own cock twitch at that. Seems it ran in the family.
Shouto’s mind was going a thousand miles per hour. He couldn’t fully comprehend what was happening, but it felt so incredibly good yet so, so wrong. He let out the slightest of whimpers, and at that point, he couldn’t differentiate if it was in protest, or to further egg his brother on.
Dabi, on the other hand, took that as a clear signal to continue. It wasn’t long before he dove in, like a wild animal hunting its prey - it was time to feast. And feast he did. Starting from the younger man’s jaw, the hand he had on his throat moving up to hold him tightly in place while suckling a spot on his neck. He could feel Shouto squirming underneath him which only fueled him more, letting his sharp teeth graze him and then bit down hard.
Still, he knew his brother’s disposition to be quiet even when in pain. It had been his only means of survival in the Todoroki household against the years of abuse from their father. Dabi wondered if he could do enough to draw loud sounds from him, hear him cry out from forbidden pleasure. God, he wanted to make Shouto scream.
He suddenly stopped and pulled away. Shouto blinked up confusedly, feeling relieved and sexually frustrated at the same time. What did Touya want from him now? Wasn’t succumbing to his touch against his will enough? Though he had to admit, at this point he wished he would continue, you know, just to get it over with. Not that the involuntary jerking of his hips forward was any indication of want on his part.
Dabi had stopped in his tracks. He decided to make it his mission to absolutely fuck with the boy’s head and hear him beg.
“What is it, baby brother? Want me to stop? You know, if you just asked me, I’d atleast consider it”, he said as he adjusted his grip on Shouto’s face, turning him rapidly upwards to face him better. “But you don’t even fight back. You’re not even trying to”, he said, shooting a menacing, somewhat provoking smile.
“Ngh…nii-san… please,” Shouto breathed with resignation.
“Please… what?”
Dabi had the look of a predator.
“I..can’t,”
“Bullshit you can’t. Come on. Make this more entertaining for the both of us”
Shouto felt as if….. as if he had to follow these humiliating orders from his older brother, and he didn’t even know why. Something compelled him.
Why did he want his brother to love him that much?
He hesitantly reached up a shaky hand towards the other’s face. He waited for a signal, for Dabi to throw it off immediately and punish him for it, but that never came. The elder sat there, showing no emotion, tentatively waiting to see where this was going. So Shouto didn’t stop. He let his hand roam his brother’s face, his beautiful, painfully mutilated face… Going softly over a single stitch on his cheekbone. He finally gently cupped that side of Dabi’s face.
“I’m sorry” echoed softly, almost inaudible, around them.
Dabi may not have expressed a trace of it physically, but he can’t say that didn’t catch him by surprise. He just continued looking pensively over at the other he’d pinned beneath his body and against the wall.
He’d grown out of emotions a long time ago.
All he had right now, was sensation.
He took Shouto’s hand off his face, (carefully, though he’d never admit it), and closed the small space between the two. He couldn’t let himself feel anything. He had no time, nor any capacity for that anymore - after all it was burned off from him, or rather, into him. He lived only in the physical. And the cock throbbing in his pants from their previous entanglement was certainly pushing him for time.
So he wasted none - the kiss was rough, their teeth clacking against each other, before Dabi took Shouto’s lower lip worrying it between his own. Shouto felt himself relax into the kiss, the familiar pool of pleasure building up inside him once again. He didn’t know why he felt like this. He didn’t care to find out.
He let himself rest like putty in the older man’s hands, moulded in whatever shape he needed him to be in. Parting his lips open for him. Feeling nauseous from what he was doing with his own kin. Feeling his dick twitch from that thought alone.
Dabi’s tongue felt rough against his own, moving frantically and with fervor. He felt the inside of his entire oral cavity, the foreign tongue in his mouth pushing far back against his throat. It went as quick as it came, leaving behind a trail of saliva and an aftertaste of ashes. It was however balanced by the pressure returning to his dick. Shouto felt like he was going to explode - he’d never experienced anything like this before, far too unversed in these matters for his own good. As if Dabi sensed this, he quickened his movements and freed his brother’s dick from its constraints.
At this stage, he could feel his own cock begging for release as he palmed it through the fabric at the same time. Shouto was leaking all over his hand, practically on the verge of cumming already. He unzipped his own pants, taking his dick out and hurriedly pressed them against each other. The friction from Dabi’s Prince Albert and mostly the realization he had his own brother’s dick against his own almost sent Shouto over the edge.
Their breathing had picked up quite rapidly, with Shouto unwillingly emitting the sweetest of little whimpers every couple of seconds. It had Dabi nearly over the edge as well, but he held out for as long as possible, etching each sound deep into his memory.
“Fuck…. Shou, you’re so, hah, good for your brother”, he leaned in, pressing their foreheads together and gruffly whispering against the other’s face, which was currently contorted in mind-numbing pleasure.
“Touya…. Please, Touya”, Shouto felt himself breathe out between whimpers. Dabi kept on rubbing their dicks against each other at a tantalizing pace, keeping them both in this space for as long as he possibly could.
“Please what? You wanna come, Shouto? Do you?”, he asked between his own ragged breaths.
“Mmhn….. I-… yes”, Shouto was trembling, his entire face taking the color of the scar around his face. He was flushed and sweating profusely. “Please, Touya, pl-“
“I want to hear you beg. Come on, tell me how much you, ah-, want to come” Dabi took his hand off, only to spit on it and cover them both with it, rotating his wrist in a way that had Shouto crying out.
“P-please.. I w-, please let me”
“Let you what?” He needed to hear this. Needed to hear his brother beg him to have an orgasm.
“Ah! P-…please let me come, nii-chan”, Shouto couldn’t believe the words that were spilling out of his mouth. He’d never spoken like this in his life, atleast never imagined himself saying this to anyone else, much less his older brother of all people. He was in a complete daze. He felt like he’s never needed something more in his life than he needed this right now. He needed his brother. He needed to come.
As soon as he heard those words, Dabi threw his head back, quickening the pace one last time, before feeling his own release building up and washing over him. “Come. Come for me, Shou”, he beckoned his brother softly. Before they knew it, their bodies were spasming ecstatically against each other, breathing heavy, engulfed in complete bliss.
After they came down and their breathing was somewhat stabilized, Dabi shoved his soiled fingers into his brother’s face and ordered him to lick them clean.
Shouto, despite experiencing a sort of post-orgasm clarity, for some reason immediately opened his mouth and did as he was told. He wanted to throw up. He kept lapping at his brother’s hand, though. He had to lick it clean.
“Good boy”, Dabi smirked. Hearing that did something that made Shouto’s stomach flip.
They stood like that in silence, relishing in the afterglow and catching their breath some more, the only thing that could be heard right then.
Just like that, Dabi stood up impulsively, swaying a bit until he found his balance after his leg had fallen asleep, and pulled himself together.
“Right. Well. Do that again sometime,” he winked at his brother as he zipped up his pants. And just like that, he went on his way, disappearing into the night. Leaving behind Shouto, who he’d left in a complete and utter mess of himself.
Shouto didn’t know how to pull himself back together. But something about that promise made him desperately want to.
