Chapter Text
"Nnynn…"
Tomura is taking his sweet, sweet time with you today, and your impatient whine does nothing to spur his movements, though it does elicit another low chuckle, earns you another gentle squeeze of the wrists.
He spreads his legs open a bit wider, and your own — draped on top of his, your feet hooked around his calves where you sit in his lap on the edge of the bed — follow suit. The air is cool and tantalizing compared to the heat of your body, and your clit pulses maddeningly, desperate to be touched.
Your head drops back onto his shoulder, your back arching as you attempt to grind yourself further onto him.
"Tomu…" you whine between soft moans, "please…"
He breathes a little heavier in response, but doesn't release your hands or increase his pace.
"Nah…" he says, turning his face into yours and kissing up your jaw, sucking on your earlobe, his breath hot against your skin. "Want you real fuckin' desperate today…"
Still with a careful hold on your wrists, he wraps his arms around your torso, pulling you tight against him as he glides tortuously in and out of you.
It's incredibly intimate — slower, more sensual than you've ever been together, you think — as his mouth works its way back down your jaw and finds your lips for a sloppy kiss. Distantly, you wonder if maybe that's part of whatever plan he has for you today. All this patience and stamina reserved so he can make you 'desperate' for whatever he's cooking up. But those thoughts are fleeting, your mind preoccupied with the way your clit is throbbing, the way your swollen walls grip his rock hard length.
- KACHUNK -
The sound registers slowly, too slowly, because there's no way that was the front door.
Because you could swear he wasn't supposed to be home until later, that you had another several hours until he made his usual stop in your doorway to greet you, like he does on the days you get home before him.
But by the time your sluggish, fucked out brain realizes what you heard and what it means — scrambling, you're shushing and squirming and trying to stop your menace of a boyfriend from continuing to fuck you in front of your roommate — it's too late.
Your wide eyes dart to your open bedroom door just as Shinsou comes into view.
"Nnononono," you babble, finally wrenching your arms free of Tomura's grip, flying to cover your chest.
"Oh, shit!" Shinsou yells.
You register the shock in his face with acute clarity before you're bending forward in a panicked attempt to hide how Tomura's dick is still buried in your pussy, your face burning. "Don't look! Ohmygod, ohhhh my fucking god…"
You can hear Shinsou backpedaling out of your room, "Dude… what the fuck," hear the door being pulled shut -
But then Tomura calls, "Oi, hang on, Shinsou-kun…"
You groan.
This goddamn menace…
"Nope," Shinsou scoffs, his voice muffled faintly from behind the half-closed door, "whatever voyeuristic bullshit you're about to pull this time, I'm not in the- "
"Don't you want to join us?"
And silence falls.
"Wh-what?" you cry, trying to look back at Tomura from your awkward position.
But he isn't looking at you. He's grinning at the doorway. You follow his gaze, and see Shinsou paused, looking away but frozen in the act of closing your door.
"Don't 'what' me," Tomura scoffs at you, and you're forced to stifle a moan at the way your awkward position makes his dick jump inside you. "You're not gonna tell me you haven't thought about him before, are you?"
You purse your lips, glaring at the floor.
First of all, fuck him. Of course you'd thought about boning Hitoshi Shinsou — with his low voice and that broody demeanor, with that full head of hair to sink your hands into and use as reins as you rode his mouth, with his arms, his arms, and that Quirk — but how dare Tomura call you out. You could never because he was your kouhai, not to mention your adoptive father's psudo-adopted son…
And second of all — what?? Tomura Shigaraki did not share.
What was happening??
Tomura chuckles again, louder this time. "See, Shin-sou-kun?" he says, exaggerating each syllable tauntingly, and to your horror, he begins to pull you upright by your shoulders. "She can't even deny it."
You can feel the heat radiating from your face, know it must be blazing red, and you squirm against Tomura's careful but strong hands on your shoulders, trying to stay leaned over to hide your chest and where you and Tomura are still joined together.
But your roommate's silence has you frustratingly curious.
Tomura's forced you halfway back to a sitting position when you chance a glance back toward the door.
You both hastily look away as soon as your eyes meet.
"And I know you've thought about her," Tomura says on a low voice that barely disguises his glee. You recognize that voice — it's the one he uses when he knows he's won. "You've thought about this pretty pussy," he says, dropping a hand to your cunt and sliding two fingers through your folds, "haven't you, Shinsou-kun?"
You can't hold back a gasp as those diligent fingers trap your clit between them.
"Yes," you hear Shinsou whisper.
Your face burns, if possible, even more red as your eyes dart back to him. He's staring at Tomura's fingers, at what they're doing to you. His hand is still on the door, but he's turned back into the room.
"Shins…?" you whisper, uncertain, almost questioning.
His eyes shift back to yours, realizing you're looking at him, as his face tinges pink, too, then his mouth twists from embarrassment into a wry grin as he looks sideways.
"I mean… can you blame me?" he says, rubbing a hand on the back of his neck, then looks back at you as he adds, "You're beautiful."
"Ooh," Tomura grunts, "hah, that got her."
Your boyfriend's an asshole but he's right. You definitely felt your pussy clench at Shinsou's words.
Tomura wraps his arms around you again and pushes up into you. "Why don't you help me finish her off, huh?"
"W-wait- " you demure, twisting, trying and failing to pull your legs together, "Tomu, this is crazy. Don't make him- "
But Tomura gives a hallow chuckle, "Ha! I'm not making him do anything," mumbling at your ear, as he lightly grips your chin, forcing you to look forward where Shinsou has dropped to his knees in front of you.
His cheeks are still pink, but he's staring at your cunt. He licks his lips before meeting your eyes again.
"Can I?"
Tomura gives another soft laugh behind you, feeling your reaction.
You wanted Shins to touch you, to taste you, wanted it more badly than you cared to admit. This was so warped… But, well, you were already here, weren't you? And fuck, the way he was looking at you...
You blink slowly, letting the surprise, the embarrassment slide from your face as your eyes close. When they open again, you let the lust settle comfortably into place — your brows relaxed and eyes lidded, a soft smirk just toying at the corner of your mouth — then nod.
Shinsou wastes no time. His hands reach out, gentle and tentative, warm and strong as they wrap around your calves. He lets out a quiet breath, lightly kneading your muscles, then slides them up and over your knees, moving to massage your inner thighs, inching painstakingly higher, as if he’s restraining himself.
His touch is soothing, and you sigh as your brain begins to turn off again, the tension leaving your body.
Encouraged by your reaction, his eyes snap to yours, his brows pinching together almost imperceptibly as he shifts, rising up from his knees, his eyes on your lips.
But Tomura puts his hand over your mouth, blocking him.
“Uh uh," he drawls, the smirk evident in his voice, "those are still mine.”
Shinsou hovers, his face an inch from yours. Your mouth had parted, ready to accept him, and you blush again.
He pulls back, shooting Tomura a glare, but lowers himself back between your thighs without arguing.
He hesitates only a second more, then leans forward, pressing his mouth to your inner thigh, and a pleasant chill runs up your limbs in response. His tongue darts out, lightly licking where he kisses, working his way steadily to your core.
When he meets your lower lips, your breath catches in your chest.
Your hands fly to his hair, deft fingers twirling and pulling at those lavender locks.
Shinsou lets out a choked moan, then nuzzles your lips apart, pressing his tongue flat against you and working in slow circles.
A breathy moan escapes you, and you rock against Shinsou's tongue, eliciting a soft "fuck" from the menace behind you.
Tomura grips your hips hard, forcing himself a little taller inside you and making you whimper. But besides the occasional twitch of his cock, the stray curse sucked in on a low breath, he stays still, letting you move as you wish and leaving the rest to Shinsou.
There's no way Shinsou is a virgin, you think vaguely, not with the leisurely, diligent way he devours you.
His movements are completely devoid of guesswork, no experimentation or watching and waiting for your reaction. That tongue is proficient, confident, like he knows just what you need and exactly how to get you there.
His mouth stays locked against your skin, creating suction that is delicious to your clit, his tongue absolutely unhurried as he savors each taste of you.
You're losing control of your breath, sharp inhales paired with breathy, melodic exhales, your pitch steadily raising with each swirl of Shinsou's tongue.
Your head drops back to Tomura's shoulder, rolling your hips back and forth on Tomura's cock, against Shinsou's tongue.
Shinsou clocks your response, and carefully ups the ante.
His thumbs work slow circles deep into the plush of your thighs. He hums his exhales, a low, gluttonous sound that vibrates against your skin.
When his lips lock around your clit, you gasp, tightening your fingers within his hair, pulling him closer, closer.
He's suckling at your clit, his tongue working in strong, tight circles.
"Hi-Hitoshi," you cry, and he stutters, his lips slipping from your clit with a vulgar sound. "Ahh, no, no," you whine, but he recovers quickly, re-latching and returning to the same steady tempo, "Don't… stop… Hi- hahhhh!"
You lose conscious control of your body as you come — your nails scraping Shinsou's scalp as you pull him desperately closer, your thighs trapping his head like a vice as your orgasm pulses through you.
Shinsou maintains steady suction on your clit, but has mercifully, expertly, stalled his tongue. He's exhaling heavily, groaning almost imperceptibly, as your ride out your high, rocking against his face.
Gradually, your movements slow, your mind sluggishly pooling back into your skull. Your thighs relax with each thrumming heartbeat, your legs falling limply back open, and you loosen your deathgrip on his hair, your fingers stretching and beginning to toy with the locks again.
Tomura is peppering kisses up your neck, whispering, "that's my girl, that's my girl," between heavy breaths.
Finally, your own breath returning to your chest, you lift your weighty head from Tomura's shoulder and look down at your roommate.
You've ruined his hair, most of it standing on end from where you'd pulled and straightened the strands, and you take a moment to tussle some of it, to push it out of his eyes.
He looks up at you with ravenous hunger, his pupils blown wide behind lidded eyes, and releases your clit with a last kiss, making you jump lightly.
"Wanna…" he breathes, his mouth hanging open, "I wanna… lick you clean… please…"
"Think you've earned that…" Tomura murmurs, the sound muffled against your skin where he continues running sloppy, open-mouthed kisses up your jawline. He lifts your hips, sliding out of you and setting you back down, still in his lap. He releases one hold on your hip and you feel him grip himself, hear him exhale ludely as he presses his cockhead against your spine.
Shinsou settles himself lower between your legs and moans as he dips his tongue past your entrance, lapping up your sopping mess, licking and slurping obscenely, like a parched man in the desert.
"Hah…" Tomura hisses, rocking himself hard against your backside. "Hurry up, kid…"
Shinsou surfaces, blinking hazily. His voice is low, honeyed with lingering lust, when he responds, wiping and licking his lips.
"Don't bite the hand…"
You clock the words, notice the subtle shift in the air, but you don't put two and two together until Shinsou rises to meet you, cradling your face in his hand, fingers hooking behind your jaw and pulling your forehead to his as he asks,
“Do you trust me?”
Only then do you understand that this is a setup.
Tomura's generosity, Shinsou's casual acceptance.
A quid-pro-quo playing out behind the scenes, beneath your nose.
And now, Shinsou is asking for your permission to use his Quirk.
You don’t know what lies in store for you, but whatever it is, it’s something that he — they — assume you’re not going to like, or at least, won't agree to willingly.
You should be annoyed, outraged even. They tricked you, pulled the wool right over your eyes as you played straight into their hands.
But you were a damn liar if you hadn't thought about this — late at night, trying not to make a sound so he wouldn't hear you through the wall your rooms shared — imagining yourself naked and splayed out, and at his mercy.
You're still somewhat wary of Tomura's intentions. But Shins… If you didn't know it of his character before today, you know it tangibly well now: he'll take good care of you.
You can sense the understanding pass from you to Shinsou, see him understand that you know exactly what you’re agreeing, too.
“Yes,” you say, maybe a bit too desperately.
You're anticipating your brain to go blank, for your muscles to move, completely out of your control, but your body is still yours, and for half a second, you panic. Had you misread this situation after all?
Then Shinsou smirks. It's similar to his usual half-smile, but there's something deeper to it now. He doesn't avert his eyes, those plum irises boring into yours, and there's a mean edge to his voice as he asks, “Are you sure?”
"Ye- ," but this time, before you can fully voice your enthusiastic consent, a strangeness seizes you — equal parts weightlessness and stiffness — as you feel yourself forcibly surrender all control to Brainwash.
Your entire body seems to scream
~Kiss me~
as it obeys with no resistance, your muscles moving as if your own neurons were directing them. Like a puppet on a string, you lean forward. Your frozen, unblinking eyes watch Shinsou's track your progress toward him, his gaze on your mouth unwavering until his lids blink closed.
Shinsou exhales softly as your lips press gently against his.
As exciting as the moment should be, it's dulled by the fact that you can't kiss him the way you'd want to. It’s way too chaste, for one, made further awkward when his lips move, but yours remain static.
Shinsou must realize this, too, because
~Like you mean it~
radiates through your entire being.
You exhale heavily as your mouth opens at last to accept his tongue. It's still not quite natural, your limbs still being moved by something other than your own motivations, but it feels much closer to what you would actually do if you weren't under Shinsou's control. You feel your arms wrapping around his neck, your fingers tangling in his hair and pulling yourself closer, when Tomura snorts.
Oh yeah.
Your body doesn't freeze, but you feel a bolt of surprise, and maybe guilt, travel down your spine. Kissing Shinsou had driven Tomura completely from your mind.
“If I wasn’t relying on Brainwash right now...” he mumbles darkly.
Shinsou gives a gloating scoff but can't do much else with how intensely you're kissing him.
You feel your desperate motions ease, and Shinsou is smiling, breathless, when you part. He nuzzles his forehead against yours, leaving your arms draped around his neck and holding him close. He gives you one more quick peck before responding.
"I'd say you deserved that," Shinsou responds, the laughter obvious in his voice.
Surprisingly, Tomura doesn't retort, just says, "Get her in a better position."
"Mm," Shinsou hums distractedly, tauntingly. "Where do you want her."
He is still stealing kisses from you, small little nips every couple seconds, like he just can't help himself, and he's getting a better handle on making your responses more natural. Your lips lock easily with his whenever he moves to take yours.
"Oi," Tomura growls.
Shinsou gives a chuckle, "okay, okay," light and carefree, and with one last long kiss, he stands, pulling you upright with him.
Tomura is tight on your heels, his dick throbbing where it's pressing into your back. His careful hands roam feather-light across your torso, wrapping you in his arms as he sloppily kisses the nape of your neck.
You remain stiff and unnatural, your wide eyes still staring at Shinsou. He's watching you hungrily, but allows you to be enveloped by Tomura.
Tomura begins rutting himself against you, his cock gliding between your ass cheeks.
"You know I wouldn't do this if I didn't think you could handle it," he whispers hurriedly, almost to himself, his rough lips tickling your skin in that way that always makes your back arch when you are in control of your own movements.
He traces two fingers down your torso, slides it back and forth a few times between your folds before swiping at your dripping cunt.
"I just thought, like this, it might make things a little easier…"
You feel him slicking himself in your mess, as your body begins to fold forward, your staring eyes now pointed at the bulge straining Shinsou's pants.
"…for both of us," he breathes, and his cockhead presses against your tight, puckered back entrance.
Oh.
Oh shit.
Tomura, no no no -
You recoil mentally from the reveal of your boyfriend's hidden agenda, but your body remains stoic, lying obediently in wait.
Shins, let me go, let me go!
But he couldn't hear you. That wasn't how Brainwash worked.
You feel Tomura's hand release your hip as he asks, "care to do the honors?"
"Don't make me regret this," Shinsou responds, all traces of his smile gone from his voice. He squats down in front of you, peppering kisses up your thigh.
You hear Tomura spit, feel it splat against your tailbone, feel Tomura's fingers move it around, coating your rim and pushing on it experimentally, giggling.
Tomura, please!
Wait, I'm not -
But you cannot speak, cannot cry out that there's no way you're ready to take him up the ass.
Tomura bends over you, planting a few more sloppy kisses along your spine, and whispers, "Okay, goddess…" then lines himself up and pushes.
You hiss, straightening your spine and forcing yourself away from him.
"What the -" he gets out before you spin around, shoving at him.
"Tomura, you dickhead!"
He looks like a deer caught in headlines. Shinsou chuckles but you spin around on him, too.
"You couldn't have just asked??" you look between them both.
Shinsou has the good sense to look sheepish. Tomura just looks confused.
"How did you break free?"
You glare but Shinsou answers, sounding guilty.
"Brainwash can be thrown off with a shock to the system… pain," he adds when Tomura continued to look confused.
You sigh, pinching the bridge of your nose, restraining yourself from smacking your dumbass boyfriend again. "You can't just .. shove it in there. I.. need some prep."
"So.. you're not saying no?"
To your surprise, it's Shinsou who says this.
You blush. "I didn't have a problem with any of it.. but I wanna enjoy it, too..."
The boys look at each other, Tomura looking as if Christmas had come early, Shinsou like he'd swallowed something unpleasant.
Tomura steps toward you, pulling you into a long kiss. He grins against your mouth when a breathy sigh escapes you. "Let's make sure you enjoy it then."
Tomura bends you forward and drops to his knees behind you.
"I really do owe you, Shinsou-kun," he says between sloppy open-mouthed kisses up your ass cheeks, then to you, adds, "you should thank him," and pinches the meat of your thigh.
"This was a .. I- I should .." Shinsou says suddenly, looking extremely uncomfortable, and turning to leave.
From your time living with him, you've come to know Hitoshi Shinsou — know how he's too hard on himself, how he takes too much responsibility for things that aren't in his control, and how he thinks he has to meet his own ridiculously high standards to feel he's earned the right to take up space — so you think you know why he's trying to flee.
You aren't certain, but you suspect to your core that Tomura had tricked Shinsou, too. Likely told him that this was something you'd wanted but were too nervous to try, that Shinsou would help make it better for you, and so he'd agreed.
But now that he knows that wasn't true, now that he knows Brainwash didn't help, that you were willing to do this without Brainwash, he can't understand what he is still doing here.
Because he thought the only reason you'd have him is at your boyfriend's suggestion, that the only way you'd want him is if you were tricked into it, and now that the mask had dropped, he had no business being with you — looking at you, touching you, enjoying you — that he was now an intruder, trespassing on your and Tomura's intimacy.
His eyes snap to yours when you grab his wrist, preventing him from scurrying out the door, and he blushes, reading the intent on your face, but allows you to pull him back, guiding him in front of you.
"H-hang on," he stutters as you start to undo his buckle, "you don't have t– " but Tomura interrupts him.
"Believe me, Shinsou-kun," he says, chuckling knowingly and spitting on your asshole again, "don't deny her this."
