“Izuku…”

Shouta has to make sure he isn’t too loud, has to keep his voice down. It’s partially his fault that they’re out here, together, and all he can hope is that if one of the other students wake up, that they have enough warning to stop and separate. But that’s only a hope, and part of it—a large part, Shouta is ashamed to admit—loves the thrill. He was doomed the moment Midoirya Izuku found out about this… preference of his, and he knows that this really couldn’t have turned out any other way than his student feeling him up in the common room of the dorms at two in the morning.

At least it’s a Friday night, he thinks, mind hazy with arousal. Two in the morning on a Friday night is probably the safest time to be doing this. Most students took off for the weekend to visit their families, and the ones who didn’t are too tired from this week’s harsh training to be up at this ungodly hour. Most, anyways, given that he has a horny second-year on his lap right now with one hand under Shouta’s shirt and the other shamelessly rubbing at the bulge in his pants.

“Wow, Sensei,” Izuku, however, seems to be far less concerned with his volume than Shouta is. This kid either has no shame right now or he’s just too horny to care and given that Shouta’s been sleeping with him for a couple months now, he knows that it’s a combination of the two. “You really do like this.”

Shouta angles his head away, unable to look at Izuku as he shifts around on Shouta’s lap. He doesn’t have to look at him to know the grin that he’s wearing, to be able to imagine in. They shouldn’t be doing this, he knows, not out here, but he can’t bring himself to push Izuku away from him and never has been able to. He draws a breath in, forcing a groan down as Izuku continues to rub at him, massaging him through Shouta’s sweatpants. Even like this, he can feel how soft Izuku’s fingers are, the way he’s taking special care to rub up and down his shaft and against the head.

“We should really…” Shouta struggles for words, struggles for control. He’s the adult here. He’s fifteen years older than Izuku. He knows that he could get into trouble for this relationship in the first place but that part is already said and done and he has no desire to change it, despite being aware of the problems it could cause. But this? This is different. They really shouldn’t be doing this. “...Should really… go back to my room.”

He does look at Izuku this time, and as soon as he sees that bright smile on his face, the way his skin seems to glow in the low light of the common room, always so happy and excited, Shouta knows he’s done for. As much as he wants to try to do the right thing and at least get them back to Shouta’s office, he can’t. He won’t. He was done the moment Izuku grinned at him and there’s no turning back now.

“It’s alright, Sensei. I promise,” Izuku assures him, rubbing his other hand over Shouta’s stomach, softly sighing as he does. “No one’s gonna see. Besides, if someone does wake up, we can just take a break! There’s a blanket right here that we can cover up with and everything…”

He has no idea how Izuku can so easygoing about this. Not only is it nerve wracking, but this is the kid who gets anxious over everything and seems to cry at the drop of a hat. Neither of those are necessarily bad things, but being so relaxed about this strikes him as odd. He knows the look on Izuku’s face, though, the bright eyes, the red cheeks, the way he pants slightly. It’s hard sometimes to remember what being a teenager is like, but he can easily recognize when Izuku is too excited about something to feel anxious about it.

(Then there’s the fact that he’s been getting more adventurous about things. Obviously, the idea of public sex turns him on just as much as it does Shouta.)

“It’d be suspicious if we were both under that blanket, wouldn’t it?” Shouta tries to challenge him, raising an eyebrow as he looks over the student on his lap. He has no intentions of getting up, though, and takes the chance to hold onto Izuku’s hips a little tighter, keeping him there as his voice takes on an almost playful tone, “I don’t usually… hang out with my students like this. It would look suspicious.”

His hands wander, starting up Izuku’s shirt. They’re both in their night clothes, Shouta having taken his costume off in favor of sweatpants and a cat shirt, Izuku in similar attire and thankfully not wearing that hideous All Might shirt Shouta had gotten him a couple weeks ago. He feels over izuku’s stomach, sliding his hand up his sides and then to his chest, Izuku seeming more distracted by Shouta feeling him up rather than what he’d just said to him.

“M—Maybe I’d move away then, if someone came down here,” Izuku’s voice is breathier, and he’s staring down at himself, at where they can both see Shouta’s hand under his shirt. Izuku’s stopped massaging his cock for now, and that’s fine—Shouta doesn’t want to get too worked up too quick, anyways, and he’s already achingly hard just from having Izuku on his lap somewhere so public. Izuku opens his mouth, swipes his tongue over his lips, and it takes all of Shouta to not lose all the composure he has left.

“It’d still be suspicious,” Shouta says, making a show out of frowning, as if he’s even considering stopping.

“I wouldn’t let you get caught,” Izuku breathes, smiling again. Shouta’s grip tightens on his hips, something bubbling deep in his chest. Izuku doesn’t seem to notice, though, “I—I wouldn’t let you get in trouble, Sensei.”

“I would protect you,” Shouta growls, not even hesitating. His fingers are tight over Izuku’s hip, the warmth of his skin radiating off of him from underneath his clothes. He leans in, something having broken inside of him, and Izuku automatically tilts his head up, letting Shouta nose at his neck. Shouta’s voice rumbles deep in his throat, “Not the other way around.”

He can see the bruising here, dark against Izuku’s skin, just below where the collar of his uniform usually sits. It’d faded and from a couple days ago and Shouta really does his best to keep his marks away from where they can usually be seen in an attempt to try to protect Izuku from questioning and other bad situations either from staff members or his classmates, but outside of his school uniform, it’s easy to see how his neck is littered with bruises and bite marks, disappearing down the collar of his night shirt and along the lines of his collarbones.

His goal is always to protect Izuku. Izuku’s his student before anything, of course, and he still has to punish Izuku if he pushes himself too far or breaks school rules, but outside of that, he does what he can to protect him. And as much of a troublemaker he can be, he’s somehow calmed down when they started all this, and Shouta’s not sure if it’s because he has a lot of Shouta’s attention now or because he tries to behave better in order to make him worry less. Regardless, Izuku’s learned to be less reckless, less risky, and though Shouta knows that he’s a chaotic kid whose first idea in any bad situation is to try to fix it himself at any cost, he’s starting to learn.

Izuku’s always been a good kid with good intentions. Shouta knows that, too. It’s part of why he’s gotten so attached to him, in a way that he’s previously forbid himself from becoming with students. He’s a problem child, but he’s a problem child with good intentions. And even if he is a problem child, then at least he’s Shouta’s problem child.

(Shouta may have a recently-discovered jealous side, but he’s definitely been trying to not think about that. Even the idea of someone else lecturing Izuku or getting him into trouble for doing something he’s not supposed to triggers it, makes something click deep inside him. Izuku’s his student. It might be possessive, but he doesn’t like the thought of other teachers even disciplining him.)

He glances over the bruises on Izuku’s neck, finding that many of them are much lighter than he remembers them being. It makes sense—it’s been a busy week and Shouta’s been swamped with work and hasn’t had a lot of time for private rendezvous with his student. He can fix that now, though, and just has to keep himself aware, watching and listening for any signs of other students, not wanting to get them caught.

Just the thought of getting caught makes his cock twitch, the weight of Izuku’s hand still resting over it, through a layer of clothing. He hears a soft giggle in response and Izuku seems to remember what he’d been doing earlier, giving Shouta a soft squeeze.

“I didn’t think you’d like this so much, Sensei—” he can hear the amusement in Izuku’s tone, cuts him off by running his tongue over one of the fading bruises near the nape of his neck. Izuku’s words end in a gasp and Shouta rewards him with kissing his skin gently before biting down and sucking, intending on making that hickey just as dark as it had been before.

He’s missed Izuku, missed hearing him knock at his office door late at night, missed him laying on his chest right before falling asleep in bed with him. It’s only been a couple days and Shouta wants to kick himself for feeling like this over a couple of days where his student hasn’t been able to be with him outside of class, but it is what it is and now that it’s the weekend, he’s wanting to save every moment of this.

“Sensei—” It’s loud and Shouta doesn’t even think Izuku’s aware of how loud he’s being.

“You talk too much.” Shouta doesn’t mean it, but he shuts Izuku up by pulling up, not wasting any time as he licks at Izuku’s mouth, swallowing one of Izuku’s moans as he slots their lips together and pushes his tongue into his warm, waiting mouth. Izuku is still clumsy, though just a little, but Shouta likes it, finds it cute and endearing. Shouta kisses him hard, hungrily, and Izuku tries to copy what he’s doing and ends up sloppily rubbing at him while making noises into Shouta’s mouth.

Izuku is the one to break them up, and it’s only because he hasn’t quite figured out how to breathe while Shouta’s kissing him yet. He pants hard, catching his breath, and Shouta sits back, leaning against the back of the couch. He watches him, Izuku’s face flushed a deep red color, every breath coming hard as he wipes the drool from his mouth.

He takes the chance to feel him up more, pushing his shirt up more so he can feel over his chest, fingers brushing over his nipples as he gropes his firm pecs, smiling a little at the muffled whine Izuku gives him.

“You seem pretty worked up already,” Shouta comments, eyeing the tent in Izuku’s pants, raising an eyebrow at him. He’s being hypocritical, of course, given how much he wants Izuku’s hands on him and not just touching him through his pants, but he can’t pass up a chance to tease him. After all, teasing him is one of Shouta’s favorite pastimes.

Izuku doesn’t call him out on the fact that Shouta’s just as turned on—if not more—as he is, though. Instead, he averts his eyes, looks away from Shouta’s face and down at himself instead, his voice going a little softer and quieter, “I missed you.”

Shouta wants to tease him more, wants to tell him that it’s only been a few days and they aren’t supposed to be doing this, anyways. But he doesn’t. He concedes, and for a moment, he lets himself be truthful with both Izuku and himself.

“Yeah. Me too.”

He doesn’t wait to see Izuku’s reaction, instead leaning in and running his tongue against his throat, abandoning moving his hands against his chest in favor of wrapping his arms around his waist and holding him tight. Izuku likes it, he thinks, if the stuttered, unintelligible reply is anything to go off of.

“Sensei…” It's surprisingly coherent and it makes Shouta pause, glancing up at him. Izuku gives him the same wide smile as before, evidently delighted to hear that Shouta had missed him, too. He rubs his hand over him and Shouta grits his teeth, holding back a noise of pleasure as Izuku’s grin just seems to grow even more, “Let me help you relax?”

Shouta’s not sure what he’s up to, exactly, but that’s alright. It’s two in the morning on a Friday night and they’re already doing this out in the common room, in public where anyone could see. It can’t get much worse—or more arousing—than this and at this point, Shouta is willing to let him do anything.

“Alright,” He agrees, and he can almost feel the happiness radiating off of Izuku. He’s so easy to please. Too easy. Shouta’s slowly become addicted to seeing that grin on his face, the sunshine that glows off of him whenever he gives in or gives Izuku something he wants.

“Lay down, Sensei!” Izuku orders him, voice a little louder than it should be, a little shriller. Shouta hates to admit it, but he doesn’t have the heart to tell him to be quiet or tease him about being too loud again.

Shouta sighs, puts on a show of moving. They're on the big, plush couch in the common room, Shouta’s work computer and grading discarded on the ground in front of them. He lays down on the couch, resting his arms above his head. The pillow is on the other side of the couch and Shouta’s not willing to get it, especially with the hungry, lustful look Izuku gives him. With a look like that, he’s not even sure that Izuku would tolerate Shouta moving.

At least there’s a heavy blanket draped over the back of the couch, close enough that Shouta could pull it and cover them both in the case of another student finding their way down to the common room. While he’d teased Izuku about it earlier, that’d likely work just fine, as long as he could get Izuku to stay hidden and quiet.

He eyes Izuku carefully and he looks so excited that he can barely contain himself. It makes Shouta smile again, the corners of his lips twitching up as he watches Izuku. He’s still a teenager, still new to sex and the excitement of being with someone older. Everything is new to him and it’s rubbing off on Shouta.

Izuku climbs over Shouta, looking at him the entire time as he nudges Shouta’s legs until he gives in and spreads them enough for Izuku to kneel between them. He watches Izuku curiously, not quite knowing what he’s preparing to do, and Shouta stays where he is, arms crossed behind his head, not shifting to touch Izuku anymore.

He gets the idea, though, when Izuku starts pawing at the waistband of his sweatpants. He’s still not sure exactly what Izuku wants, but he has an idea. He still says nothing, though he lifts his hips a little, Izuku giving a small, excited noise as he immediately takes advantage of what Shouta’s letting him do. He pulls down on the waistband, not bothering to take his pants completely off, just getting them down enough that Shouta’s cock is out in the open. He can’t help but to be a little appreciative, given that it was starting to get painful and uncomfortable, with Izuku just lightly touching him through his clothes.

Izuku shoots him another grin, scoots back, and Shouta finally realizes what he’s doing as Izuku lowers himself, dropping his head until the head of Shouta’s dick brushes against his full, red lips. His cock twitches at the realization and suddenly, he’s even more interested, simultaneously just as on edge. Izuku already seems very intent on sucking him off here, in the middle of the common room, when any of his classmates could come out of their rooms and easily see them.

“Just relax, Sensei,” Izuku tells him, reaching out and wrapping a soft hand around the base of his cock. Shouta tenses, trying to keep himself from getting so worked up so soon, embarrassed about how he’s already completely hard and aching. He’s not some teenager, but sometimes with Izuku, he definitely feels like he is.

Shouta sucks a breath in when he sees Izuku’s tongue flick out, wetting his lips. He studies Shouta’s cock with wide, green eyes, and Shouta’s reminded of the first time he’d ever tried to blow him, how amusingly inexperienced he’d been and how he’d clearly just been trying to do… whatever he’d seen in the weird porn he watched. He’s tried his best to teach him, but if he’s being honest, he does think Izuku’s inexperience and sloppiness is a little cute.

(Part of Shouta knows that he likes being the older one, the wiser one. He likes Izuku looking up to him. He likes being able to teach him and make him happy. He’ll never admit to it out loud, admit that he likes their age gap, but it’s something he knows deep, deep inside.)

Izuku’s gaze connects with him again as he looks up at him from his place between Shouta’s legs. He doesn’t hesitate or tease him anymore, leaning in more and pressing a kiss to the head of his cock, Shouta holding in a groan as he watches. He can see how red Izuku’s cheeks are, the bruises on his neck and collarbones, the way his fingers squeeze the base of his cock. He’s tempted to reach down and thread his fingers through Izuku’s dark green hair, but doesn’t, saving that for later. Izuku wants him relaxed, anyways. Shouta might as well relax as much as he can when they’re doing this in a public space.

Izuku’s mouth is hot and wet and he wastes no time in taking Shouta inside. He can see the way the corners of his lips are still pulled up, Izuku still smiling at him even as he takes the head of Shouta’s cock into his mouth, a quiet noise rumbling in Izuku’s throat as he twists his tongue around him, flicking at the slit on the tip. He’s gotten much better at this, even in the recent few weeks, though he still can’t quite take all of Shouta down his throat.

He can’t really blame him. It’ll take some more practice. Shouta’s thicker than average and it makes sense that Izuku has trouble working him into his mouth without choking. Shouta’s more than pleased with anything Izuku can do for him and in any case, he’s very willing to train him and there’s lots of time to do so.

Right now, though, he just does what Izuku told him to in the first place: lay back on the couch and relax let, letting Izuku do what he wants with him.

“You’ve been practicing.” Shouta’s voice is low, rumbling in his throat. He feels his cock twitch in Izuku’s mouth, head pressing against the inside of his cheek. Izuku gives a long suck, almost making Shouta forget about what he’s just said, and then pulls off. He slides his other hand up his shaft, thumbing at the head as he stares with half-lidded eyes at Shouta, running his tongue up the length before he answers him.

“Just a little.” Izuku’s clearly trying to keep quiet, his voice breaking and squeaking a little as he tries to keep it hushed. He leans in, kisses the underside, just below the head of his cock. He’s learned a lot, obviously having learned what Shouta likes the most and paying special attention to those things the most.

“With who?” Shouta drops the tone of his voice, though it’s hard when Izuku’s touching him like this. He can feel his student’s hot breath over his cock as Izuku laughs quietly.

Shouta knows the answer. He’s teasing. He’d never actually show any sort of serious jealousy around him. Izuku is, of course, allowed to have other relationships, especially with those his own age. Shouta’s slight possessiveness is his to deal with and his alone.

“Not who, Sensei. What.” Another long lick up his dick, this time from the base to the head, before Izuku flicks his tongue into the slit for a moment. He won’t look at Shouta when he says it, still embarrassed, even though they both know Shouta’s just teasing him, “I just… really like the vibrator you gave me.”

He’d been expecting that answer, but Shouta likes seeing him so embarrassed. Izuku hides his face by taking him into his mouth again, slipping a little further down his cock. Shouta keeps his breathing measured, reaching down and pushing a hand into Izuku’s curly hair, slowly and lazily stroking it as Izuku hollows his cheeks and sucks on him.

“I can tell. You’re doing good—” Shouta manages to praise him, biting down on his bottom lip as he starts to fight to keep himself quiet. He looks up at the ceiling of the common room, the floors of the dorms... At any second, someone could wake up and come out of their rooms. The thrill of it spurs Shouta on further and he fights to keep his eyes open as Izuku shows him just how much he’s been practicing lately.

Shouta doesn’t expect him to be able to take him all the way down, but Izuku surprises him by getting over halfway there. He’s still remembering to breathe, still remembering that Shouta likes him to use his tongue and likes him to pay more attention to the head of his cock. He’s getting better at this. Much better. Shouta’s impressed.

He strokes his hand through Izuku’s hair, going between watching the upper levels of the dormitory and watching Izuku as he drools over Shouta’s dick, bobbing his head up and down as much as he can. Izuku’s hand works the rest of him, his soft, uncalloused fingers stroking the base of his cock, even wandering down further to touch his thighs and even dipping lower to curiously fondle his balls. Shouta quickly loses track of time, quickly unwinds, only focuses on listening to Izuku’s noises as he sloppily sucks his cock and the pleasure coursing through his body as the minutes pass.

He moves his hand down, at first stroking across Izuku’s freckled cheek. Izuku opens his eyes a little wider, batting his long eyelashes at him in a way that’s almost comical. His green eyes are watering from the effort he’s putting in and a tear will occasionally slip down his face. Shouta wipes them away with his thumb, strokes Izuku’s cheek again before moving down.

He trails his hand over his still-soft jawline, down to his neck. Izuku’s in a position that lets Shouta see down his shirt and he’s more than appreciative of the view. Izuku always wears such baggy shirts to bed, sometimes with low necklines. He wonders if Izuku would consider wearing shirts with an even lower collar if Shouta bought him some. He files that away as something to think more about later.

He runs his fingers over a couple of the faded bruises and then over the one he’d darkened earlier, already standing out more against the rest. He really needs to be careful, because Izuku doesn’t have his neck covered all the time and Shouta’s already pushed it several times and left bruises close to where the collar on his uniform sits. Izuku changes in the locker rooms, too, and Shouta wonders—and definitely doesn’t fantasize about—if any of the other boys have ever said anything to him about the multitude of lovers’ bites on him, if Izuku has ever had to blush and come up with an excuse while trying to hide his body.

He likes that thought a little too much. More than he wants to admit.

Izuku’s a highschool student, of course. It isn’t too odd for him to have markings. Highschoolers are unbelievably horny and Shouta’s already convinced that half his class is sleeping together. Still, he doesn’t want to give anyone any clues as to where Izuku’s getting his marks from, so it’s just better to not leave them where people will obviously see them

He keeps going. His hand dips under the collar of Izuku’s shirt and he flutters his eyelashes up at Shouta again, as if telling him to keep going. He pulls off of Shouta’s cock, taking a couple deep breaths, before switching his technique. Shouta doesn’t mind—he loves it when Izuku kisses the length and licks at the head, working his still inexperienced tongue around him. That’s just what Izuku does, going immediately back in, plump red lips pressing wet kisses against his cock, a small moan escaping Shouta.

Izuku takes that as a compliment, kisses the vein on the bottom side of his erection. Shouta strokes his fingers over Izuku’s collarbone. He doesn’t waste much time there—Izuku is a lot smaller than him, small enough that Shouta can easily reach his chest from this position. He reaches further down, brushing his thumb over Izuku’s nipple, making him let out a small sigh, and feels around his chest, smiling down at the student currently sucking him off.

He likes Izuku’s body a lot. Smaller than him, lighter than him—Shouta likes being older than his partners, but also bigger than them. Izuku’s decently muscular, as well, and Shouta likes that, too, especially since it gives his chest a little definition, enough so that Shouta can fuck his cock between his firm breasts if he wants to—and has, of course. How could he pass up such a wonderful opportunity like that?

He gropes at Izuku’s chest, rubbing at one of the firm pecs, squeezing and feeling him up. He hears Izuku whine in response, sees him shift around so that Shouta can touch his chest more, inadvertently pushing his hips out with the way he’s knelt between Shouta’s legs. He watches Izuku with hungry eyes, Izuku unintentionally wiggling his hips a little more as he dips down further to get into position again.

“Izuku,” It comes out as more of a gasp than Shouta means it to be. He swallows hard, tries again. “Off.”

Izuku immediately pulls off of him, sitting up and looking at Shouta with confused eyes. Shouta wastes no time in explaining, though he does take the time to slide his hands under Izuku’s shirt so he can grab at his chest more.

“I want you to ride me,” He says simply, bluntly. He has a bottle of lubricant somewhere around here, though he’s a little disappointed he has to use one hand to try to find it. Luckily, it doesn’t take long, and when he looks back up, Izuku looks undeniably giddy from excitement. “I want you to finger yourself, too. You think you can handle that?”

“Y—Yeah, of course, Sensei,” Izuku grins, bright, moving to get off of Shouta. Shouta watches him as Izuku takes his pants off, throwing them onto the other side of the couch, and looks him over closely. His hard cock is dripping and Shouta hadn’t missed the prominent wet spot that had been left on the front of his pants. It’s a little amusing, how it bounces a little with every movement he makes. He’s smaller and less thick than Shouta and it reminds him every time he looks at him of their age difference.

Izuku had actually been shocked the first time he’d seen Shouta’s cock. He hadn’t seemed to realize that the dick of a fully grown, thirty year-old man was going to be different than the dick of any teenager he’d fooled around with. That naivety still shows its face from time to time, though not now, given that Izuku grins at him again and climbs over Shouta, this time sitting over his hips.

The first time Izuku ever asked him to actually fuck him, he’d been scared that his cock wasn’t going to fit inside of him. Now he’s trembling with excitement, his breath coming in quick gasps as he settles himself and reaches out for the lubricant Shouta has without any hesitation.

“Wait,” Shouta doesn’t give it to him yet. Not quite. “Shirt off, too.”

Izuku immediately does what he says, quickly pulling his shirt over his head, discarding it near his pants. If only he listened that well in school.

Shouta rewards him and gives him the lubricant, laying back once more to watch. Izuku slicks his fingers, two of them already, and then reaches behind him. Shouta feels his legs spread more, watching his smaller cock bob with the movement. Izuku’s mouth falls open and he sighs softly and Shouta knows he’s pushing his fingers into himself.

Izuku holds himself up with one hand on Shouta’s hips. His legs are trembling, clenching around Shouta’s. He can just barely see between his spread legs, where Izuku’s fingers are moving in and out of himself as he gets himself ready for Shouta’s cock.

It’s a sight to see. He really does love Izuku’s body. He can feel him even more like this. Izuku moans quietly when Shouta presses his larger, more calloused hands against his stomach, feeling his muscles there, his eyes searching over the scars on his student’s arms from his quirk. He makes his way back up to his chest again, gently pinches Izuku’s nipples, tearing a high-pitched moan from him.

That makes Shouta stop, but only for a moment. He looks up towards the ceiling again, searching over each floor of the dorms, Izuku falling silent—or as silent as he can be—as well. There’s no one, though, and as far as Shouta can tell, they’re safe. He rubs his thumbs experimentally over Izuku’s nipples again and Izuku makes a muffled, quiet noise.

He reaches up a little further and guides Izuku down until he can kiss him, gently threading his fingers through his curly, slightly sweaty hair. Izuku kisses him back, as enthusiastically as ever, though Shouta can tell that he’s distracted by the fingers he has inside of himself right now. That’s fine; Shouta’s alright with doing all the work and he kisses Izuku deeply, licking at his lips and taking his sweet time to explore his mouth, only letting Izuku up when he needs air.

Izuku gasps, panting, as he collapses against Shouta’s chest. He stills for a moment, quietly whimpering, and Shouta realizes that he hasn’t touched his cock yet or allowed him to touch himself and Izuku is completely desperate to get off.

He can wait a little longer, Shouta decides. It’s been a busy week. He’s missed Izuku.

“Okay—” Izuku gasps out. “I… think I’m ready.”

“So soon?” Shouta teases, wearing a small smile as he rubs his hands over Izuku’s back. He helps him sit back up, more than a little impressed at Izuku’s self control to not rut against him.

“Like I said… I’ve been practicing.” Izuku won’t look at him, his face beet red and glistening a little from the leftover tears caused by sucking Shouta’s cock and the sweat on his forehead. His hands shake, clutching Shouta’s thighs tightly, clearly trying to keep himself from trying to get off on him without permission.

“Oh, good boy,” Shouta praises, taking mercy on Izuku. He takes the bottle from his hand, pours some onto his hand, and finally gives himself a bit more relief, as well as he strokes his cock. He does it a little longer than necessary, stroking himself from base to tip as Izuku watches him. Shouta almost thinks he’s about to start drooling on himself, and stops before that happens.

“Okay, go ahead,” Shouta instructs him, laying back and relaxing once more.

Izuku’s legs tremble and shake and his student can barely hold himself up. Shouta has to guide him a little, firmly planting his hands on his hips, nudging him until Izuku is kneeling over his cock. One look into Izuku’s face tells him that he’s gone, made too incoherent by lust and Shouta holding off on him for so long. It’s worth it, though, and he’ll make sure that Izuku feels just as good as him. He wouldn’t be a very good teacher if he didn’t at least reward his student for doing so well and even practicing outside of class.

He pushes down on Izuku’s hips and Izuku gets the idea, starting to lower himself onto Shouta’s cock. He can’t help the long groan that escapes his throat as he feels the rim of Izuku’s ass brush against the head of his cock and only hopes that none of the students will wake up, since Izuku’s whines are gradually getting louder.

Izuku drops himself down onto Shouta, taking him into him in one go. Shouta clenches his teeth, fighting to keep silent, and a hiss of pleasure escapes through his tightly pursed lips. Izuku looks like he’s in bliss, though he grins at Shouta, hardly giving either of them any time to adjust before he’s pulling himself off of him and pushing back down, starting a fast pace.

This is far from the first time Izuku has ridden him. It’s far from the last, as well. It is, however, so far the best, and Shouta is reminded once more that Izuku has been practicing. It shows, the way he’s grinning, gasping and letting out quiet sounds as he bounces up and down on Shouta, clearly having gotten the hang of fucking himself on a cock.

“Fuck—” Shouta hisses, starting to lose his composure. Izuku must be really insistent on having Shouta just lay back and relax, because he’s definitely trying to do all the work himself. He’s pulling himself off of him and bouncing his hips back down, thrusting the full length of Shouta’s cock back inside of him with every movement. Izuku’s hardly even nervous anymore and clearly eager to show Shouta how much he’s learned and how excited he is.

It’s easy to lose himself inside of Izuku. The fact that they’re doing this out here, in the open, under the bright lights of the common room of the dorm, makes it hotter, dirtier. Shouta’s a thirty year-old high school teacher, fucking one of his second year students out where just anyone can see if they only just come out of their room. It’s exhilarating and all Shouta can feel is the warmth and impossible tightness of Izuku around him, the excitement just seeming to radiate off of him with every thrust down onto Shouta’s cock.

Izuku doesn’t even seem to be concerned with getting himself off. Shouta’s been with him enough to know that Izuku can come untouched if Shouta fucks him hard enough—but he’s never yet come untouched from riding Shouta. Sometimes he begs, sometimes he asks nicely, and sometimes, if Shouta teases him enough, he’ll break and just demand that Shouta touches him. But he’s doing none of that now, keeping his hands braced on Shouta’s shoulders, leaning forward enough that Shouta has a fantastic view of everything, from the way his green curls hang around his face to the slight sheen of sweat covering his forehead and clinging to his cheeks.

He slides his hands up Izuku’s body, feeling over the muscles in this stomach and abdomen to his chest again. Izuku’s fingers tighten over his shoulders and Shouta takes his chance, meeting Izuku’s body as he pushes his hips up as his student pushes himself down, grip tightening on him as he angles himself, trying to hit Izuku’s sweet spot.

“Sensei—!”

“Shh,” Shouta grins as he hushes him. Izuku stills for a moment, panting, but quickly picks back up again, pulling himself almost completely off of Shouta before dropping himself back down, taking Shouta inside of him completely in on go, forcing a low moan from Shouta’s throat. He fights to keep quiet, despite having just teased Izuku about being too loud and it’s almost too much—

He aims for Izuku’s prostate again, realizing that Izuku really doesn’t have any concern for his own pleasure right now. Or maybe he just doesn’t know how to get the right angle. Whichever reason, it’s fine. Shouta’s older, more experienced. He can teach izuku and right now, he wants to see if he can make izuku helplessly come all over them both without Shouta even touching his cock.

It’s dripping now, pre-cum rolling down Izuku’s smaller shaft in heavy drops and he’s starting to make a bit of a mess on Shouta’s stomach. It bobs with every bounce and thrust and Izuku’s panting is getting heavier and heavier, his noises becoming more frequent as Shouta manages to get himself into a better position and hit his sweet spot every time.

Izuku’s thrusts quickly get sloppy and Shouta’s trying to keep himself under more control. It’s hard, though, when he’s fucking Izuku relentlessly in such a public setting. Shouta’s always had a fetish for public sex, something he hasn’t let Izuku find out about until now, and now that he’s got his cock buried deep inside Izuku’s ass in the middle of the dorm’s common room, it’s harder than usual to hold on.

He can feel the way Izuku’s muscles clench around him, as if trying to drag him deeper and deeper inside of him. It’s unbelievably hot inside, and Izuku is as tight as ever, even though Shouta knows just how much he’s been fucking himself on that vibrator he gave him. He needs to get Izuku to come first, though, wants to see him become even more of a mess, overstimulated and loud and shaking and—

Shouta freezes.

Two floors above, a door slams.

Izuku freezes, too, clamping a hand over his mouth, the sound of just that movement echoing through the building.

For a moment, Shouta doesn’t breathe, doesn’t move. Luckily, neither does Izuku. Shouta’s still inside him. Izuku’s still on top of him, completely naked, Shouta’s dick buried as far into his ass as it’ll go. And… there’s footsteps. Of another student. Approaching the stairwell. Maybe even about to reach the railing, where they can see down and into the common room. In that moment, Shouta’s eyes go wide as he tilts his head up, hardly able to focus as his cock throbs inside of Izuku.

A student. His eyes fall on a head of pink hair, clumsily walking out of her room. A student. His student. A very specific student. A very specific student who’s about to catch her homeroom teacher in the middle of fucking one of her classmates. He has to do something—

—He’d promised Izuku that he wouldn’t ever let him get in trouble for this.

Shouta can lose his job—lose his hero license, potentially—if he gets caught. But right now, that doesn’t matter. What matters is that he doesn’t want Izuku getting into trouble, doesn’t want him to be hurt or upset by someone discovering their relationship. That’s what tears Shouta out of his lust-filled frozen stupor.

There’s a blanket on the back of the couch. He’d made sure it was there when Izuku had told him to lay back and relax. He can’t completely remember what his plan had been—had he even had one? He’s terrible at forethought when it comes to his problem child, admittedly—but the gears turn and Shouta just does the first thing his brain comes up with.

He grabs Izuku, pressing him down on his chest. Izuku goes easily, silently, his hand still clamped over his mouth, and Shouta can feel how tense he is as he lets Shouta push him into his chest, how every muscle in his body is pulled tight. He catches a flash of Izuku’s eyes, the way they’re blown wide and filled completely with fear, the aroused, lustful look from before having faded completely. It just awakens the usually-prominent protective even more within him.

Shouta snatches the blanket off the back of the couch, throwing it over them, effectively covering both their bodies. Izuku tries to duck under it, apparently thinking that this is all Shouta has in mind for hiding, but Shouta puts a hand at the back of his head, nonverbally telling him to keep still.

It’s silent enough that two floors up, Shouta can hear Ashido Mina fumbling with her room keys, cursing quietly under her breath as she looks for the right one.

Shouta takes advantage of that and rolls them over, pressing Izuku against the back of the couch, Shouta laying on his side. It’s better like this—Shouta’s bigger than him. A lot bigger. He has more muscle on him, as well as more weight. He’s taller. Like this, he can completely cover Izuku’s body and help hide him in the couch cushions. He can’t see up into the atrium anymore and can’t see exactly where Mina is, but that’s alright. Izuku’s safe and since Shouta’s on his side with Izuku pressed into his chest, it just looks like Shouta alone is asleep on his side—which isn’t that odd, given that he’s fallen asleep on the couch before.

He fixes the blanket so that it covers the rest of Izuku completely, though he leaves enough of a gap that Shouta can see him and Izuku doesn’t take his wide, terrified eyes off of him.

“It’s alright,” Shouta assures him, lowering a hand to guide Izuku’s legs around his waist a little better. His voice is a low whisper, quiet enough that Shouta can barely hear his own voice. “I told you I’d protect you, remember? I’m not going to let us get caught. Just relax and stay quiet.”

He brushes his hand through Izuku’s hair, meaning it as a soft, affectionate gesture, and Izuku leans his head into his touch a little, just as Shouta feels something twitch against his stomach.

Izuku’s still hard. And Shouta realizes that not only is he still hard and buried inside of Izuku, but he’s still just as close to orgasm as before.

Logically, he shouldn’t be. The prospect of getting caught should terrify him to the point where he should’ve been turned off the moment he heard the noise of a door slamming shut. His plan should’ve been to pull out of Izuku, hide him, and then get the hell out of the common room as soon as Mina left, maybe take Izuku with him back to his apartment and tell him to just go to sleep because he was too tired to pick up again. That’s the most rational plan, and Shouta likes to think of himself as a rational man. But in reality, he’s not.

The adrenaline of getting caught courses through his veins, makes his heart beat faster. Izuku feels so small against him, and Shouta wraps his arms tightly around him, pulling him closer to him. It doesn’t help that he can feel Izuku relax a little as Shouta holds him tight, some of the tension flowing out of his shoulders and arms. Izuku’s cock twitches against his stomach again, some of his pre-cum rubbing onto his skin and telling him that Izuku is just as aroused by this as he is.

There’s footsteps. Shouta can’t see her anymore, but he knows Mina’s headed for the stairs. He’s not sure why, given that it’s way, way past curfew and the kids all have private bathrooms. Mina might be outgoing and energetic, but she’s not one to break curfew, or even any rules The only thing Shouta can think of is that she needs something from the kitchen and in that case, he can only hope that she won’t be long.

Izuku’s smaller hands clutch at his shirt. Shouta leans in enough that he can rest his chin on Izuku’s head. Unless anyone’s looking for him, he’s completely covered, completely protected and hidden. No one would be able to tell that Shouta has one of his students naked and curled up against him.

He can hear Mina in the stairwell, now. She’s loud, thankfully, not seeming to care who hears her heavy footsteps or yawning. Shouta’s heartbeat picks up more, thudding hard in his chest. She’s so close to finding them, of completely catching him fucking a student and yet—she’ll never find out.

Shouta pushes his hips forward slowly, not enough to really move the blanket, but enough to move inside of Izuku. The slide is blissful, the feeling of Izuku’s tightness clenching around him just amplified by the thrill of being caught in a public setting. He’s so close, and Izuku’s ass is so warm and tight and inviting, taking Shouta’s cock hungrily.

“Sensei…” It’s a quiet, whispered whine. Shouta pulls away enough to look down at him, to whisper back to him.

“Do you want me to stop?”

He will if Izuku asks. He’ll stop in a second. He’d do anything for this kid, truthfully, and the last thing he wants is to hurt him or do anything he doesn’t want. Shouta likes being older and bigger and the more dominate person, but when it comes down to it, Izuku has all the control between them. If he doesn’t want this, Shouta won’t do it.

But Izuku shakes his head, tilting his face back up at him. He doesn’t want to stop, and Shouta watches as he quietly whispers one more short plea—

“Please keep going.”

He wants to praise Izuku, to tell him that he’s such a good boy, that Shouta will take care of him and make him feel good. He can’t say any of that, though. He just has to show him.

The footsteps grow louder and louder. Mina hits the first floor. Shouta waits a moment, pulling the blanket more over Izuku again, properly hiding him once more. The footsteps keep going, though, right into the kitchen.

Shouta unwraps an arm from Izuku, instead grabs one of his thighs. His legs are wrapped around Shouta’s hips and his leg muscles are clenched tightly, keeping Shouta deep inside him. He wraps his fingers around his student’s thigh, supporting him more and hiking it up a bit, giving Shouta easier access.

He goes slowly. Usually, he doesn’t go slow once he’s close to orgasm, but right now, the slow drag of his cock in and out of Izuku’s ass is just making things hotter. His hole is a mess, from the lube from earlier, as well as the pre-cum from Shouta. It’s even easier to fuck him now, especially with Izuku’s legs wrapped around his hips like his life depends on keeping him inside.

Water’s running in the kitchen now, and Mina’s moving around it. Shouta makes sure to keep silent and Izuku is apparently trying pretty hard, too, from how quiet he’s being, just like Shouta had told him. Shouta’s cock throbs with every push and pull of his hips, pleasure pooling at the base of his spine and spreading through every inch of his body, setting his skin aflame. The water stops and Shouta doesn’t still, listening as Mina turns the lights off in the kitchen.

He holds his breath, though he still doesn’t stop, and waits for her to start moving again towards the stairs, waits for her to just get a little further away so he can go a little faster. It won’t be much more now, maybe just a couple more sharper thrusts and he’ll be coming deep inside Izuku’s ass.

She doesn’t move away, though.

Instead, her footsteps get closer.

She steps into the common room and Shouta’s so startled that his hips snap forward, slamming into Izuku, clenching his teeth and just barely holding on as his closes his eyes tightly and rests his chin on Izuku’s head.

Below him, Izuku gasps, Shouta’s dick throbbing hard as he focuses on trying to force himself to hold back in favor of protecting Izuku. He’s covering Izuku’s body again and he draws out each breath, covering Izuku’s sharp gasp with a fake-sleep sigh of his own.

Luckily, Mina doesn’t seem to notice. She takes a few more steps, and then stops completely. Shouta holds his breath, not moving an inch, and then hears Mina let out a high-pitched coo.

“Sensei’s so cute! Shouldn’t sleep on the couch, though…”

Oh no.

He really should’ve known that this would not be as simple as her just going back upstairs to her room. He should’ve known that she’d be nosy and want to investigate what her teacher was doing asleep on the couch in the common room.

She doesn’t just stop there, either. She puts Shouta’s ability to protect Izuku to the test and starts to creep towards him. Shouta glances down at Izuku, making sure that he’s properly covered. She’s so close, so close to finding them out, so close to finding out that Shouta’s fucking a student in the dorms. She’s so close—too close— close to catching them.

He wishes that this wasn’t as arousing as it is. He wishes he wasn’t trying to keep himself from coming inside of Izuku right now. But he is, and if she doesn’t go away, he won’t be able to hold back any longer.

Of course, she doesn’t go away. Instead, she jabs her finger right into his shoulder.

It startles Shouta. It makes him jump, makes his hips snap forward as he buries himself into Izuku one last time, covering Izuku’s sharp gasp with his own shout of surprise. He keeps himself wrapped around Izuku, having at least the sanity left to do that, and the pleasure courses through him. There’s no more holding back, and Shouta comes deep inside of Izuku, forcing himself to stay quiet as he slowly opens his eyes, finding another student in front of him, staring at him with wide eyes as she peers at him from over the back of the couch.

“Oh, Sensei! I’m so sorry, I didn’t mean to scare you so much. I really didn’t, I promise.”

Shouta can barely comprehend the words.

Don’t look down.

He’s silently begging her not to. Izuku’s covered and there’s really no way for her to know that he’s here. That didn’t make it that much better, though, because the waves of pleasure are still washing over him and his dick is still throbbing and hard as he empties himself inside of Izuku. He doesn’t even think he can speak without stuttering or moaning, so he clenches his teeth, shuts his mouth, and does his best to glare at her as he raises a hand to rub his eyes.

If he could scare her off, they’d be fine. He had just come inside of Izuku, of course, but even now, he can’t necessarily say he regrets it, given how earth shattering his orgasm is.

“Okay, fine,” Fortunately, Mina seems to get the idea, putting her hands up in defeat and backing away. “But Sensei, sleeping there is bad for your health!”

She runs off again, his plan having worked perfectly. He waits, finally letting himself breathe normally, panting to get his breath. It’s only when he hears her at her door and fumbling with her keys that he finally uncovers Izuku, though he presses a finger to his lips to tell him to keep being quiet.

He can’t really see Izuku’s face, since he’d hidden it in Shouta’s chest, but he can see the red tinge of his cheeks. Upstairs, he can hear Mina unlock her door and open it and slowly, Shouta slides a hand under Izuku’s thigh, guiding it up so he can finally pull out of him, feeling weak and a little shaky from his own orgasm. Some of his cum drips out, too, spilling onto Izuku’s thighs, and Shouta only then realizes just how much he filled Izuku.

He runs a hand through his long hair and Izuku pulls away from him, silently looking up at him.

“You can talk now,” Shouta says, hoping that Izuku knows to still keep it down a little. Shouta’s hot all over, sensitive from coming in him, but Izuku immediately rolls on top of him again.

“That was amazing,” Izuku tells him in an excited, hushed voice. He’s straddling Shouta’s hips again and he can feel the wetness of his own cum spilling out of Izuku’s hole and onto his skin. He doesn’t mind much, as long as it means that he doesn’t get it on the couch.

“We almost got caught,” Shouta hisses, though it’s half hearted. He takes pity on Izuku, glancing down to see that his student is still hard, and he lets out a fake sigh and wraps a hand around him, trailing a hand up his side to guide him down onto his chest.

“Isn’t that the point?!” Izuku’s voice cuts off in a moan and his lips sloppily meet Shouta’s. Izuku’s even clumsier now, as if it’s his first time kissing Shouta, and Shouta gives in to him, squeezing his length and moving his fist over him at a fast pace, trying to give Izuku even a fraction of the pleasure Shouta had just felt. It’s relieving, at least, that Izuku had enjoyed that as much as Shouta had. Shouta doesn’t like to be a selfish lover and really does wish he could’ve made Izuku cum before him, but he supposes that that can be saved for a different time.

He’ll have to remind Mina that getting in his personal space when he’s sleeping isn’t a good idea, either. Shouta’s convinced that he could’ve held on for a lot longer if she hadn’t come so close to fully catching them.

Izuku seems to forget what they were talking about and within a few moments, he comes with a moan in Shouta’s hand, making even a bigger mess out of the two of them. Thankfully, though, nothing gets on the couch—but Shouta will have to wash this blanket and maybe even replace it so that he isn’t constantly reminded that the kids are using a blanket that he fucked one of his students on. Or maybe he can keep it and use it with Izuku more, though he’s definitely going to be washing it a few times.

Shouta gives Izuku a minute, letting him collapse onto his chest and catch his breath. He wants to thread his fingers through Izuku’s hair and fall asleep with him like this, but they’ve already pushed it way too much for one night and it’s Shouta’s job to make sure that his inexperienced partner gets cleaned up and put to bed properly, and he’ll see to that no matter how tired he is. So regretfully, he sits up, letting Izuku stay in his lap.

“Come on. I have to get you cleaned up. You’re a mess.”

Izuku just hums, like he’s already half-asleep. Shouta nudges him, trying to wake him up. It’s a lot of excitement for one night and Izuku’s already worn out from upcoming exams and hero training, but Shouta would rather have him asleep with him in his actual bed than out on the dorm couch.

“You can stay with me tonight,” Shouta tries instead. That gets Izuku’s interest. It’s not really a bribe, since that’s been Shouta’s plan this entire night and it’s not too rare for Izuku to stay with him, but Izuku always seems to pick up mood-wise or wake up a little when he mentions it. This time is no exception. “I’ll even carry you if you really can’t walk.”

“Deal.”

Now Shouta has an excuse to carry Izuku around with him, too, and he’s more than happy with that.
