The living room is dark save for the tv that's been playing some random show Aizawa cares nothing about. The room is cool and comfortable, and Aizawa has never been more thankful for the extra space or the peace it affords him. The extra space is one of the few good things about the teacher's accommodations in the student dorms.
Aizawa has his own single room apartment on the first floor of the class 1-A dorms as well as an apartment he keeps off campus. He rarely uses his space at the dorms, only ever stays in it when he's been saddled with weekend guard duty for his problem children—Which just so happens to be this very weekend.

Aizawa sits up from where he's lying on the couch and stares at the clock on the wall. It's just past midnight on a Saturday and most weekends are quiet, so quiet Aizawa forgets he even owns a cellphone. So he's hesitant to pick up his phone from the table for fear of who could possibly be calling him this late. He's not in the mood to deal with any bullshit from his band of misfit students.
Bzzt Bzzt Bzzt
The phone buzzes again and Aizawa stares at it for a moment longer before being resigned to pick it up and finally see who it is. The screen lights up and Aizawa grins down at the face staring back at him. It's Shinsou, an annoyed expression on his otherwise pretty face as Aizawa quickly snaps the picture. Most of the students have his number in case of emergencies, so it's not unusual that he's calling in general, but it is odd that he's calling right now.
Bzzt Bzzt Bzzt
Aizawa taps the green button on the screen and puts the phone to his ear, prepared to listen to some ridiculous scenario that Aizawa will no doubt have to handle.
"This better be good, Shinsou. It's midnight so if no one is dead then-"
"Ngh! Fuck... deeper, deeper yes yes yes."
Aizawa nearly drops the phone.
"Shinsou?" He asks hesitantly into the receiver, and gets nothing but heavy breathing and a drawn out moan in return.
Had Shinsou butt dialed him? How the—?
"S-Sensei, please—ah ah! Harder!"
Aizawa is listening to the filthy, wet slapping sounds of Shinsou fucking himself as he calls out for him. He's staring at his phone in stunned silence, Shinsou the only thing that can be heard in his quiet apartment…
"I'll be so good, I promise! Harder, harder please!"
Aizawa is on his feet and out the door in seconds. He bounds up the stairs, completely ignoring the elevator, and takes them two at a time all the way to the second floor.
The air feels staticy around him, charged and heavy as he marches to Shinsou's room. He can still hear the boy on the phone, the lewd noises and breathy little pleas he lets out as he begs for more—for Sensei as he does god knows what to his body.
Aizawa's mind supplies him with countless images of Shinsou in any and every position imaginable, and it does nothing to quell the storm raging inside him. Shinsou had called out for him, had begged for his sensei as he fucked himself naked and alone in his room…
This was the last straw.
The endless flirting, the shameless looks and the sly touches Shinsou thinks he's playing off as little accidents during training… Aizawa has had enough. No more teasing and no more toying around. He's going to show Shinsou exactly what it is he's been begging for this entire time.
Aizawa stands in front of Shinsou's door, phone still clenched in his white knuckled fist, and tries to steady himself before going inside. But he can still hear Shinsou panting through the phone's speaker and the tell-tale knock of the bed as he pushes himself ever closer to that glorious end—and Aizawa loses the ability to control himself.
He uses his faculty key to unlock the door and walks into the room to finally lay eyes on the source of what's been tormenting him over the last handful of minutes.
And what a fucking sight it is.
Shinsou is completely naked, just as Aizawa had suspected, and kneeling on his bed. He's got one hand wrapped around his dick and the other steadily working a dildo in and out of his ass. And Shinsou doesn't notice Aizawa until he's closing the door behind him. The faint click of the lock engaging pulling the boy's attention instantly.
Surprise—shock—horror all pass over his face in the span of the few seconds it takes Aizawa to move from the door to the edge of the bed. He's completely frozen, eyes wide as he watches Aizawa walk across his bedroom. He finally snaps out of it when he sees the phone held in Aizawa's hand, Shinsou's name visible across the screen.
"No, oh god no—sensei, sensei I can explain—fuck, no no no no." He's panicking, fumbling around until he can hide his nudity with the sheet he pulls from the bed. As if Aizawa hasn't already taken in every inch of him and committed it to memory.
Shinsou searches frantically for his phone, patting around on the bed and twisting to look behind him. Aizawa spots it on the floor, just beside his bare foot, and kicks it underneath the bed. Shinsou won't be needing it anyway.
"You want to explain to me how you moaned my name so loud your phone called me?" It's cruel, but Aizawa is enjoying how terrified Shinsou looks right now.
"Sensei… I—"
"You can explain?" Aizawa let's his gaze roam Shinsou's bare chest and pale thighs not being covered by the sheet clenched between the boy's long fingers. "I don't believe I need you to explain, Hitoshi. I know exactly what you were doing. I heard it, every sigh and moan and sensei like I was right here in the room."
Shinsou looks terrified, face red with embarrassment at being caught like this. And Aizawa is definitely enjoying this far too much. But he's owed this after the months of shameless flirting and teasing he's put up with.
"If I didn't know any better I'd say you did it on purpose." He adds, just to enjoy the way Shinsou's face reddens further.
Shinsou's mouth drops open, stunned, as he struggles to get himself together enough to deny the accusation. "What? No! I would never—"
"Never what? Never shamelessly flirt with me day in and out? Intentionally let me pin you during training so you can rub your ass against me? Eye fuck me in the locker room? What is it, Hitoshi? What would you never do?"
Aizawa doesn't wait for an answer, knows he's not going to get one, and reaches for Shinsou's leg to pull him to the edge of the bed. The boy yelps as he's dragged, hands flying out to try and balance himself before he finally stops and Aizawa is standing between his legs.
"Well, you don't have to wait anymore. Because I'm finally done playing your little games." Aizawa yanks the sheet from Shinsou's body. He's so stunned he barely fights as he's finally laid bare for his Sensei to devour.
"Wait, w-wait sensei."Shinsou tries to cover himself, and Aizawa only just stops himself from cooing at him. How precious. Aizawa grabs the boy's wrists and pins them above his head as he spreads himself against Shinsou's body.
"Wait? For what? I listened to the way you moaned and cried out for me, Hitoshi. I know how much you want this." He can still hear those sweet sounds coming through the phone. The way the bed had squeaked just before every little whine and the way Shinsou's voice had risen as he called out for him.
"No, no, please. Wait, I don't—I mean, I'm not re—"
"Not ready?" Aizawa finishes for him, his free hand snaking its way down Shinsou's chest and across his pretty cock before slipping easily between his lube-slick cheeks. "But you were taking that so easily just a moment ago."
Aizawa gives a pointed look at the dildo, once buried in Shinsou's ass, now discarded and forgotten at the opposite end of the bed. "To be fair, I am much bigger than your little toy. So maybe you aren't ready."
Shinsou's eyes go wide and Aizawa let's his fingers toy along Shinsou's rim, the tip of his finger sliding in and out with such ease Aizawa can't stop himself from letting the whole thing slide into the searing heat of the boy's body.
"Sensei, p-please…" Shinsou pleads under him, body shaking and back arching as Aizawa touches him.
Aizawa isn't listening. He's far too mesmerized by the way Shinsou's body swallows his fingers. He's added another one to the finger already inside him. And god, Shinsou is tight and hot and so, so wet.
He curls his fingers, curious as he explores the trembling body, and feels his own dick twitch in his pants when he hits that spot inside Shinsou and he arches off the bed, a gasp pulled from between his lips.
"Ah! Stop, please, please stop." Aizawa can see the tears beginning to streak down Shinsou's face, can hear the way his voice waivers and breaks with each word—and Aizawa fucks a third finger into Shinsou's ass because he can.
"You were begging for me only a moment ago. 'Harder, sensei', remember?" Aizawa spreads his fingers, stretches Shinsou open to get him good and ready. "You've been tormenting me for so long I think it's time I show you what it is you've been begging for."
Aizawa pulls his fingers free and flips Shinsou onto his stomach. His ass is perfect, toned and round and made to be spanked. Aizawa reaches for him and Shinsou pulls away, scrambling up the bed.
"Sensei—" Aizawa cuts him off by yanking him back to the edge of the bed by his hips.
"I can always tie you down, Hitoshi. There's no point in pretending you don't want it. You said you would be good for me, was that a lie?"
For all his whining and begging and tear streaked cheeks, Shinsou's dick is still hard between his legs. There was no point in playing shy when it's so obvious he wants it.
"You've always been a greedy little whore, Hitoshi. I knew it the first time you bent over for me in the locker room. You wanted me to look."
Aizawa feels Shinsou's breath catch when he pulls out his cock, not even bothering to strip, and drags the head against the boy's slick hole. "You wanted me to fuck you then. I could hear it in the way you moaned like a slut when you thought I was gone. Did it feel good to fuck yourself on your fingers and think of me?"
Shinsou chokes out a sob, fingers twisted in the sheets, and Aizawa grins as that sob turns into a garbled moan when he pushes the head of his cock past the loose, silky ring of muscle. He's tight, tight and wet and sucking Aizawa in inch by glorious inch all while moaning so loud Aizawa worries someone may actually hear him.
"Begging me to stop one minute and moaning loud enough for everyone to hear you the next. You that desperate for my dick, kid?" Aizawa pulls Shinsou's hips back as he pushes forward to bury himself completely in Shinsou's body. He's squeezing Aizawa with enough force to steal the very air from his lungs—it's divine. "Is it everything you wanted?"
Aizawa fucks him slowly, taking his time to listen to the way Shinsou's whines and watery pleas turn to breathless moans every time he bottoms out.
"I don't-I don't want this." Shinsou cries, and then immediately buries his face into the mattress so Aizawa can't hear how filthy his moans sound. "Please, please stop!"
"Stop?" Aizawa slams forward, forcing his dick inside and rocking Shinsou against the bed. "You should have thought of that sooner, Hitoshi. Because now, now I'm going to fuck you good and loose so you never forget. Ah ah, you don't get to hide."
Aizawa pulls Shinsou up off the bed and wraps his arm around the boy's chest. He wants to hear every cry and moan and pathetic little sob that leaves his lips. He only wishes he could see Shinsou's face as he ruins him…
Aizawa looks around the room and grins as he spots the mirror on the sliding closet door. It's directly in front of the bed and Aizawa barely has to turn to see their combined reflections. He pulls Shinsou off the mattress, the boy letting out a distressed yelp as he's manhandled, and then immediately pulls him back onto Aizawa's lap as he sits down on the edge of the bed.
Shinsou's legs are draped over either side of Aizawa's thighs and the boy has no choice but to look at himself, at how hard he is, and watch as Aizawa pushes back into his body until Shinsou's tear filled eyes roll back into his head.
"I want you to watch, Hitoshi." Aizawa instructs, one hand wrapping around Shinsou's dick while the other wraps around the long column of his pale throat. "You can beg and cry all you want, but I'm not going to stop."
Aizawa can see everything. He can see the way Shinsou's hole is stretched obscenely around his thick cock. And the way tears roll down the boy's face as Aizawa begins to stroke his pretty little dick while he fucks him. Shinsou isn't begging anymore, isn't telling Aizawa to stop, and he likes the way the boy has given in so easily.
Nasty little whore.
"I'm going to ruin you."
Shinsou is trying to hold back the noises steadily being pulled from his throat, but each twist of Aizawa's hand and rock of his hips has Shinsou moaning and panting into the open room until his chest is rising and falling rapidly with each ragged breath he takes.
Aizawa drinks it all in, every inch of bare skin and the way Shinsou's body responds to his touch. Shinsou's breathing is picking up, his body clenching and unclenching around him, and Aizawa groans knowing Shinsou is already so close.
"Gonna cum for me already? I expected better from you." Shinsou is shaking his head, a denial, but the flushed, leaking head of his cock and the way his thighs shake against Aizawa's legs tell a different story.
"Pathetic little boy. You wanted a man's cock and now you can't take it?"
Aizawa tightens the hand wrapped around Shinsou's throat and uses the leverage to fuck into him harder. Shinsou would scream if he could, if Aizawa wasn't nearly choking him as he splits the boy open. The muffled, breathy scream has Aizawa so close to the edge he can barely see straight.
But he won't cum first, not until he sees Shinsou make a mess of himself. So Aizawa holds back, slows down, and moves all his focus to getting Shinsou off as quickly as he can.
He doubles his efforts, spitting in his hand and wrapping it around the base of Shinsou's dick. It's an angry almost purple now, and Aizawa is dying to feel the boy shake against him as he cums. To see him cry and fight and ultimately succumb to the pleasure he so readily denies he even wants.
"Open your eyes, Hitoshi." Aizawa growls when Shinsou looks away from the mirror, eyes squeezed shut against his own obscene reflection.
"No! I don't want this! Please—!" Aizawa shoves three fingers down Shinsou's throat.
Shinsou gags around the intrusive digits immediately, and his entire body jerks and clenches around Aizawa until he's moaning right in the boy's ear.
"Shut up and cum," There's an undeniable edge to Aizawa's voice, and Shinsou tenses against him. "Or next time my dick gets shoved down your throat."
And that's all it takes. Maybe Shinsou imagines choking on Aizawa's dick, or maybe he needed a little push, a verbal command. Or perhaps it was the possibility of a next time that does it. Either way, barely a second after the words leave Aizawa's lips Shinsou is spilling messily all across his own chest and Aizawa's hand.
"Of course you would cum thinking about swallowing my dick. Sensei's little whore, isn't that right?" Aizawa chides as he continues to stroke Shinsou through it, watching the way his body positively shakes as his orgasm consumes him.
A fresh batch of tears leak down Shinsou's face as he watches Aizawa continue to stroke him with his own mess. It's unendingly satisfying to see him struggle and fight against it, to feel Shinsou's throat constrict around his fingers and his tongue roll against his palm.
There's so much cum dripping down his hand and running down Shinsou's stomach, Aizawa barely resists the urge to lick the boy clean. He imagines the taste of him on his tongue and Aizawa releases another growl as he rocks into the perfect heat of Shinsou's ass.
There's no point in fighting it when he feels that heat start to build again. Aizawa chases it greedily, hand still slowly stroking Shinsou's spent cock just to feel the way the overstimulation makes Shinsou bear down around him.
Aizawa uses him. He bombards Shinsou's sensitive body with stimulation until he's fighting against it and fucking himself on Aizawa's cock. It's twisted and perfect and his release hits him so hard he sinks his teeth into the soft, pale skin of Shinsou's shoulder as he empties himself into the boy.
Shinsou is shaking against him, body limp but still milking Aizawa through his orgasm as he leans heavily against Aizawa's chest. And Aizawa can't stop staring at the two of them in the mirror. It's the perfect image.
Shinsou looks destroyed, beautiful, utterly ruined and Aizawa can't bear to take his eyes off him. His tear streaked face, the flush covering his body, and the mess slowly leaking down his thighs and onto the floor. Aizawa wants to preserve this moment for the treasure that it is.
He pulls his phone out of his pocket, unsure of when it got there, and unlocks it before snapping a handful of pictures. The shutter noise draws Shinsou's attention but for once, he doesn't say anything and immediately looks away when he notices what Aizawa is doing.
He wanted this too. Of course he did.
"Hitoshi," Aizawa murmurs against Shinsou's ear. "Look at me."
The way Shinsou fights it brings a smile to Aizawa's face. But eventually he meets Aizawa's dark gaze in the mirror, a war of wills sparking to life in their reflection. Those violet eyes are red and puffy from crying, and narrowed on Aizawa with so much anger he can taste it in the air.
"The next time you bat your pretty eyelashes at me, eye fuck me in the locker room, or so much as breathe in my direction—I won't be so nice."
Shinsou's mouth opens like he's got something to say, and then immediately snaps shut. Whatever it was, the boy thought better of it. Aizawa is almost disappointed he learned his lesson so quickly.
"Good boy." He hums, before quickly standing and dumping Shinsou back on the bed. There's no need for him to stay any longer so Aizawa quickly fixes his pants, dead set on a shower as soon as he gets back, and heads for the door.
"Oh, and your phone is under your bed." He tosses over his shoulder, an afterthought, just as he walks out of Shinsou's room.
Aizawa doesn't see or hear from Shinsou for the remainder of the weekend. He's not at all surprised by it and spends the remainder of the weekend sleeping and making sure the rest of his students don't do anything more ridiculous than usual.
Monday comes, as it always does, and Aizawa is back in the classroom, back to teaching and training like nothing has changed. Even though something has very obviously changed. Shinsou hasn't made so much as a peep all day.
They make it all the way to their usual after school training session before Shinsou will even look at him.
"Seems someone learned their lesson. I like you much better behaved like this."
Aizawa doesn't expect him to say anything, so when Shinsou utters a quiet, "Sensei?" Aizawa thinks nothing of it when he answers, "what?"
And then his entire world goes black.
When he wakes up he's completely naked and bound in one of the training buildings. Hidden away so no one can see. Shinsou is straddling his waist, grin on his face and violet eyes aflame with something so intense Aizawa feels his heart pound at the sight of him.
"I think it's time I taught you a lesson, Sensei."
Oh how the tables have turned.
