Chapter Text
The fields and mountains rolled past the windows in an endless cycle of various shades of greens as a bus carrying the students of 2-A and Aizawa sped through the country roads on the way to Shiketsu High. The two schools had decided to team up for some joint training, UA being the ones to make the journey, to Aizawa’s dismay.
Bakugo was sat at a window seat, staring out at the fields and mountains, earphones in, ignoring the surrounding chaos of his friends to the best of his ability. This trip had come as a surprise to him, just as it did for the rest of the class, but Bakugo, unlike everyone else, was kinda pissed about it. He knew it would have been slightly unethical for Aizawa to tell him about it privately, but a heads up would have been nice. Bakugo felt like he deserved that.
While it had only been about a month since this…arrangement between the two of them had started, they had definitely gotten closer. In more ways than one, at least Bakugo believed, and hoped, so. The whole thing was going quite well, better than he could have imagined.
The sex was amazing, each time has been more than enough to help quell Bakugo’s ragging anger, subduing him for days at a time. Bakugo had to admit, it felt good not to be angry, it gave him the chance to concentrate on other things and allowed him to actually, sometimes, enjoy being around his friends. The last time even helped Bakugo get past his fear of being strangled, well, at least by Aizawa. Bakugo wasn’t exactly keen to test it out with someone else. But the point was, he was making progress. And he was happy about that. Although, he also had some concerns.
There was clearly something going on with Aizawa, or more accurately, something going on inside that man’s head, something he wasn’t completely voicing. He had said that he didn’t want to hurt Bakugo, but Aizawa’s concern seemed like more than just that. It worried Bakugo, what if Aizawa wanted to stop this? What if he actually hated being dominate like this?
Bakugo huffed an annoyed breath. It sure didn’t seem like his teacher hated it. Aizawa was a good damn natural. He turned it on when necessary, and turned it off just as easily. Bakugo liked that, but it was kind of annoying too.
The other night, Aizawa had been pretty rough. The roughest he’s been, and it resulted in slight bruising on Bakugo’s neck and some grazes on his back from the hard table. Which if fine, Bakugo didn’t care. But Aizawa, he seemed pretty bothered by it. Like the marks were a reminder of what he had just done. And he seemed to hate it, or hate himself for causing it. But that’s just how it is with this kind of thing, isn’t it?Aizawa would have to get over it. Shouldn’t he be used to seeing his students injured, as morbid as that may be?
After Aizawa’s little freak out, and Bakugo was made to promise his teacher that he would speak up if he didn’t like something, the man had insisted on carrying Bakugo to the bathroom. At the time, he had felt a little embarrassed but allowed Aizawa to do as he wanted, thinking they might go in together. But no, Aizawa practically dropped him into the bath and left him there alone. Annoyed, Bakugo ended up staying in there for a while, soaking in the hot water, stewing over the fact that Aizawa was so indifferent sometimes. It pissed him off.
By the time he go out, Aizawa had wound up on the couch watching tv, but as soon as he stepped into the living area, Aizawa sprang to his feet, rushing Bakugo into the kitchen. The counter was laid out with a few bandaids and a cream. Bakugo tried to protest, saying he didn’t need it, but Aizawa wasn’t having it. So in the end, Bakugo was subjected to standing in the kitchen with his shirt off as Aizawa slowly covered each graze with cream, and a bandaid for the deeper ones.
At the time Bakugo had acted annoyed, but he’d be lying if he said he hated it. It was nice, the feeling of his teachers hands on his body in a non sexual way felt so calming, and it was just nice in general to have someone care that much about his well being.
Bakugo slipped in and out of thoughts regarding Aizawa as the bus continued on towards their destination, a surge of annoyance working its way through his mind as he remembered once again that Aizawa hadn’t told him about the trip. They were going to be away for three nights. THREE NIGHTS. And it’s already been two since they last had sex. Never mind a heads up, Aizawa should have given him a good fucking last night. How the hell was he going to survive a school trip with these idiots, not to mention the idiots from Shiketsu, without being rail at least once? Impossible.
—
Meanwhile, Aizawa found himself in much the same place, staring out the window deep in thought. Or more like in emotional turmoil; regarding the marks he left on Bakugo’s body yes, but also something else. And somehow, this something else is much more troubling to him.
It was easy being with Bakugo, it was easy giving the boy exactly what he wanted, it was easy being dominate, too easy. The things he did, the things he said, it came so naturally in the moment it scared him.
Aizawa wondered if it was so easy due to Bakugo being so much younger than him, but he wasn’t sure. Maybe he was just naturally dominate, and Bakugo, surprisingly naturally submissive. They had good chemistry, there was no denying that.
But Aizawa was worried, scared even, that he’d get too rough, take things too far, say something out of line. It was like he got possessed when they were doing it, the dominate part of his personality taking over.
Up until recently, Aizawa had been ignoring this feeling of unease, but he literally choked his student the other night, hard enough to leave a bruise. If Bakugo had problems, then so did Aizawa.
He couldn’t ignore it anymore, but that didn’t mean he knew what to do about it. The smart thing, the best thing would be to end this now, before he did go too far. But if Aizawa was being completely honest, he didn’t want to end it. Mostly because he didn’t want to cause an even worse outcome, ie. Bakugo getting upset, pent up, angry, and surely recklessly seeking out someone else to fill the role. Aizawa may be afraid of his own strength and dominance, but he knew there were way worse men out there who could hurt Bakugo in more awful ways than he ever would. Of course, there were also other reasons Aizawa didn’t want to end it, but he refused to think on those reasons for very long.
—
Aizawa stood back, leaning against the wall somewhat unprofessionally as he watched students from both schools come to the front to draw names. The idea was that for the first joint training exercise, a UA student would be paired with a Shiketsu student and they were to complete a series of tasks together. The pairs were to be drawn from two boxes, each with a set of numbered ping pong balls, the students with the matching numbers from each side would then become a pair.
Aizawa was feeling tired and lethargic from the long bus ride, but the teacher of the Shiketsu 2-A Class had insisted on starting straight away. So here they were, in an extremely large gym at Shiketsu High.
Slowly but surely each student came to the front to collect a ball and had started pairing up accordingly. Aizawa watched with tired eyes, not exactly interested in the results of the pairs. He had no idea who any of these students were, or what their quirks were. Except for Inasa Yoarashi, whom he recognised from the Provisional License Exam, and the Supplementary course. But he had never actually spoken to the kid.
Aizawa’s vision focused ever so slightly as Bakugo strode up to the box, pulling out a ball, before he made his way to the side joining the students that had pulled a number but had not found their pair yet.
Aizawa was far enough away that he didn’t quite hear Bakugo state his number, but someone large stepped out from the crowd, clearly showing his numbered ball, grin on his face. Inasa.
Aizawa watched with interest as Bakugo made his way towards the boy, swiftly side stepping when Inasa’s large hand came towards his shoulder. Aizawa found himself smirking, Bakugo was infamous for his skills of avoiding physical contact. If only everyone knew just how much Bakugo actually liked to be touched. By the right person and in the right way, of course.
Bakugo brushed off another outstretched hand before turning to the front, catching Aizawa’s eye.
Aizawa froze at the sudden eye contact, but then looked away quickly. A little embarrassed he had been caught watching.
The next thirty minutes or so trudged on slowly as the final pairs formed and the Shiketsu teacher explained the first task. Aizawa zoned out for the most of it, but essentially the pairs were to complete an obstacles course, a very elaborate one that had been set up before they arrived, without using quirks. They were to work as a pair and reach the finish line together in the quickest time they could. By the looks of it, the students were going to have to work together, as in physically push and pull each other up and over some of the obstacles. Aizawa’s jaw clenched.
The students were then given five minutes to observe the obstacle course and discuss within their pair the best strategy at completely it.
Aizawa continued to watch on without comment as pair after pair attempted the course, each having their own method, but every method did indeed seem to involve physical contact. A lot of it. With each pair, Aizawa’s stomach twisted more and more with a feeling he couldn’t quite place, but it definitely wasn’t a pleasant one.
Before long Bakugo and Inasa stepped up to the starting line and took off with a sprint to the first hurdle at the sound of the horn. While the pair made their way through the course in a swift manner, 1 minute and 45 seconds, the shortest time so far, it felt like an eternity to Aizawa. As all he could see were large hands all over every inch of Bakugo’s body. His legs, hands, arms, his waist, even his ass, as Inasa hauled Bakugo around like he weighed absolutely nothing.
Aizawa knew, realistically, that this should not be bothering him. But it was, and he didn’t know what to do with that.
—
Tired and stiff, Bakugo and the other students of 2-A made their way into the hotel lobby hours later. Training had been exhausting, arguably fun in Bakugo’s opinion, but tiring nonetheless.
They were staying in a hotel close to Shiketsu High, but had to wait for Aizawa to check in with the staff and assign rooms before they could go wash up and have a much needed dinner. Some students still possessed the energy to talk loudly to each other, analysing and gossiping about everything and anything that happened today. But others, like Bakugo, stood or sat quietly, tired and waiting.
“Okay, gather round and be quiet. It’ll be two to a room, I have the keys here.” Aizawa held up the room cards in one hand, his expression beyond tired. “But there’s a problem. As you know Mineta wasn’t allowed to come on this trip because, somehow, he failed the mid semester test. That means there’s an odd number amount of boys. So, someone will unfortunately, for the both of us, have to share a room with me. I’ll draw a name from this box to keep things fair.”
Murmurs and complaints echoed across the expanse of the male students, seemingly no one was very keen on sharing a room with their teacher. All except Bakugo of course. He would not mind one single bit, in fact it was preferable. Furthermore, the thought of another student being in such close and personal proximity to Aizawa made Bakugo’s stomach churn with fury.
Bakugo watched silently with narrowed eyes as Aizawa reached into a box containing pieces of paper that had seemingly sprung out of thin air, anxiety building in his gut. Aizawa extracted a piece, slowly unfolding it. “And the unfortunate student is….Bakugo. Congratulations.”
The class turned to Bakugo and exploded into laughter. Trying his best to look pissed off about the outcome, he crossed his arms over his chest, tsking. Really, he couldn’t be more pleased, his anxiety and that awful bubbling of jealousy and anger subsided instantly.
“Man. That’s rough buddy.” Kirishima smacked Bakugo on the shoulder, sending him forward by half a step. Bakugo huffed, “fucking bullshit,” as he continued towards Aizawa, swiping the key card from him with a growl.
Aizawa smirked down at Bakugo, which could have been seen as teasing, this is what you get for being the biggest problem student, but Bakugo knew Aizawa was simply pleased with his fake ‘pissed off’ acting. Surely Aizawa was just as pleased as Bakugo was, that it was his name that came out of that box.
As soon as all the rooms were assigned and the room keys were handed out, Bakugo followed Aizawa up to their room, continuing his pissed off attitude, hands in his pockets, scowling at anyone who dared to laugh or comment. After entering the room and pulling the door closed behind him though, Bakugo fully relaxed.
“Well, thank fuck for that, huh?” Bakugo threw his bag onto one of the beds, kicking his boots off. Aizawa hummed, not looking Bakugo’s way as he placed his own bags down on the other bed. Bakugo sucked his teeth, Aizawa could at least properly confirm he was relieved. Discomfort swirled in his gut. Maybe Aizawa wasn’t happy about this for some reason he couldn’t possibly fathom.
“Tsk whatever. I’m gonna shower.” Bakugo started digging through his bag for a change of clothes and his toiletry bag with a new scowl in place.
“Okay, I’ll go eat first then. I’ll leave your room key here,” Aizawa slid the card onto Bakugo’s bed as he walked past and out the door with so much indifference that Bakugo almost cursed him out. Clutching his belongings in a tight fist, Bakugo stormed into the bathroom and slammed the door.
—
By the time Aizawa was finishing up his meal, Bakugo strode into the dining hall skin flushed from a hot shower, wearing a black t-shirt and those tiny shorts he always wore up to Aizawa’s room. He clenched his jaw, dropping the piece of food he was previous holding with his chopsticks. That damn brat. Even if they weren’t involved in whatever it was they were involved in, Aizawa was of the opinion that those shorts were way too short to be appropriate, they were basically boxes. He was sure he’d still feel that way, even if they were just teacher and student.
Aizawa thought Bakugo must be doing it on purpose, trying to provoke him. Why else would he wear shorts like that in front of his classmates. Aizawa huffed, pushing out his chair. He was not going to fall for it.
Back up in the room, Aizawa stood in the shower letting the hot water flow over his body, trying to distract his mind of thoughts of a certain somebody. It was proving to be difficult however as the humid air swirling around the shower smelled extremely familiar, looking around the shower to find the source, Aizawa saw that Bakugo had brought his own body wash. That’s it, that’s what the smell was. Bakugo. Aizawa’s cock twitched with interest as his forehead thudded against the titled wall.
This was embarrassing honestly. First the displeased feelings of Inasa touching Bakugo, and now he was getting hard just because he smelt the boy’s body wash? Aizawa didn’t quite understand why Bakugo was effecting him so. But he was travelling down a dangerous path, he knew that much at least.
After a much too long shower, Aizawa shut the water off, dried himself, pulled his pants on, forgoing his shirt, and hung his towel around his shoulders to catch the drips of water from his hair.
As he exited the bathroom, he was shocked to find Bakugo back already, sprawled out on the bed, scrolling on his phone. Aizawa stopped to look at the boy, but Bakugo seemingly ignored him. So he carried on to his bag, pulling out his work laptop, turning to set it up on the built in desk that ran along the expanse of the wall, a large mirror covering the rest of the wall above it.
“Are you not going to fucking dry your hair?” Bakugo’s angry voice made Aizawa jump.
Without turning around, he replied bluntly. “It’ll dry.” That boy really needed to watch his tone, and his swearing.
Bakugo scoffed, launching himself off the bed. “The fuck it will. Get you fucking sick is what it’ll do, leaving it like that.” Aizawa watched without comment as Bakugo stormed into the bathroom.
Shortly after, he returned with a hair dryer, roughly plugging it into the wall and pulled the desk chair out. “Sit down.”
Aizawa stared at him, he couldn’t be serious. “You don’t need to blow dry my hair for me Bakugo.”
Bakugo stared back, looking anything but impressed. “Well you’re as hell not going to do it. Sit down.”
Aizawa sighed, he knew there was no point in trying to argue with the boy, so he crossed the room and sat down in the chair.
Bakugo really had the audacity to shake his head, like Aizawa was a troublesome child, before he placed the dryer down and moved behind him. Taking the towel from Aizawa’s shoulders, Bakugo carefully squeezed out the dripping water. “You didn’t even towel dry it. What’s wrong with you?” If Bakugo meant for that to be condescending, it sure didn’t come out right. It sounded too soft, endearing almost.
“Sorry…I guess…I’m just lazy,” Aizawa didn’t really know what to say. He felt like he was being scolded for his bad attempt at being an adult. But he somehow didn’t really mind. After all, it was arguable that Bakugo had his shit together better than he did. In some ways at least.
Bakugo didn’t say anything, but shook his head again, grabbing the hair dryer and switching it on. Like before, his ministrations were surprisingly careful as he gently combed through Aizawa’s hair with his fingers, massaging his scalp when he got down to the roots. Slowly but surely, Bakugo made his way to the front of Aizawa’s head, kicking his legs open so he could stand between them.
Aizawa kept his head down, eyes on Bakugo’s thighs. They were so white and creamy, hairless and unblemished. Without really thinking about it, he reached out with both hands running them up the expanse of exposed skin with feather like touches. Bakugo flinched at the sudden contact, but carried on with his blow drying without saying a word.
Distracted by the feeling of Bakugo’s skin against his fingers, Aizawa didn’t notice that the hair dryer had been turned off and discarded until Bakugo finally spoke. “Finally acknowledging my existence now?”
Caught off guard, Aizawa snapped his head up, eyes connecting with red ones. “…Excuse me?”
Bakugo pouted, averting his eyes. “…before, when we came up to the room. You barely even spoke to me, let alone look at me….and then you just left.”
“I…you said you were going in the shower…” Aizawa was confused.
Bakugo looked angry, huffing as he turned around and pulled the hair dryer plug out of the socket, winding the cord around the handle.
Aizawa thought back to earlier, sure he hadn’t said much before going down to dinner, but what was there to say? He didn’t think his actions, or lack of apparently, were anything that would be what, hurtful? Or even noteworthy. Bakugo really was such a handful. Standing up, Aizawa moved behind his student, placing a hand on his shoulder, looking at Bakugo’s face through the reflection of the mirror. But Bakugo kept his gaze downcast, lips still in a pout.
“Hey, I’m sorry. I didn’t mean anything by it. I didn’t notice I was being…distant.”
Bakugo’s eyes flicked up, scowling an awful amount. “You’re not very conscious of your own actions are you?”
At that, Aizawa couldn’t help but huff a laugh. He felt called out, again. Dropping his forehead down to Bakugo’s shoulder, and slipping his hand down Bakugo’s arm, he couldn’t help but feel a sort of fondness for the boy. “You’re right…I’m sorry. I’m not the best at noticing other people’s feelings and acting accordingly. But I’ll try. From now on, I’ll try to make more of an effort. With you.” What was he even saying, not eight hours ago on the bus Aizawa was wondering if he should cut this off. But he realised he really meant what he said, he really did want to make more of an effort. But why? So Bakugo wouldn’t be upset? So he wouldn’t feel insecure in this…relationship? Did Aizawa even really owe Bakugo that? Probably not, but Aizawa wanted to ensure it anyway. One thing was for sure, Bakugo was messing with his head. Not deliberately, but he was.
Aizawa both felt and heard Bakugo sigh, “I’m just being a nuisance. Ignore me.” Aizawa shook his head, “you’re not. And I couldn’t ignore you now even if I tried.” Moving his hand back up Bakugo’s arm, the other one found the boys hip, squeezing it lightly. Aizawa raised his head, just enough to begin peppering kisses up Bakugo’s shoulder and to his exposed neck.
Bakugo shivered ever so slightly, arching his neck to give Aizawa more room, a quiet whine escaping his mouth. Flicking his eyes to the mirror, Aizawa caught Bakugo’s gaze, the look on his flushed face sending sparks of arousal and the feeling of possession through his veins. Moving his hand from Bakugo’s arm to his stomach, Aizawa began snaking his touch up the boy’s torso, stopping to grope his sizeable pecks, pinching each nipple as he continued kissing Bakugo’s neck.
Bakugo arched his chest into the touch, his ass simultaneously brushing against Aizawa groin.
Aizawa stepped forward, bringing their bodies even closer together, grinding his hips up into Bakugo’s ass, his cock already filling out. Aizawa suddenly wanted him so badly.
Loosing himself to his arousal, Aizawa slid his left hand drown from Bakugo’s hip until he was reaching between the boys legs, fingers snaking up the leg of his tiny shorts and underwear. By passing Bakugo’s hard cock and soft balls, Aizawa’s fingers found their way to the boy’s hole, brushing over the rim before he froze. “You…you didn’t prep yourself…?”
Bakugo shook in Aizawa arms, body pulled taunt in his hold, speaking through clenched teeth. “I considered it. In the shower. But I thought there was no way in hell you were going to fuck me. We’re literally sharing both walls with those damn extras.”
Aizawa clenched his jaw as his cock twitched in arousal and annoyance. Who cares. He wanted to be buried deep inside Bakugo’s warmth right now. “Did you bring lube?” His voice practically came out as growl.
Bakugo moaned as he pushed his hips back, but his reply was just as charged. “Why the fuck would I have brought lube? I couldn’t have know we’d end up in the same room. Or that you would wanna fuck me. I can’t believe it was my name you even pulled out of that damn box..”
Aizawa chuckled cruelly before moving his lips up to mouth against the shell of Bakugo’s ear. “Did you reaaally think I just so happened to pull your name out, hmm Katsuki?”
Bakugo gasped, stuttering out a response, “w-what?” Aizawa watched him in the mirror as his eyes grew wide.
Aizawa smirked, reaching his hand up to lightly grasp Bakugo’s neck, pulling him even tighter. “There were no names written on those pieces of paper. I was always going to pick you. I was hoping I’d be able to reprimand you for bad behaviour, say it was your punishment. But you were a good boy all day. So the other students would have been suspicious…..Well, mostly good.”
“M-mostly? What are you talking about?” Bakugo’s red eyes narrowed.
Aizawa hummed as he began running his hands all over Bakugo’s body. “That brute had his hands all over you, and you didn’t seem to mind one bit. In fact, I think you even liked it.”
Bakugo choked back a moan as Aizawa pinched his nipples, quickly recovering with a growl. “Fuck you. I did not.”
“Oh? But you’ve been with lots of men right? And wouldn’t Inasa be perfect for you? He’s big enough to man handle you, throw you around. He’s bigger than me…” Aizawa spoke against the skin of Bakugo’s neck. In the back of his mind, Aizawa questioned why he was even speaking like this, taunting the boy. But the part of his personality that liked being dominate out weighed his better judgment to stop.
“You seem to manage just fine…” Bakugo started to squirm in Aizawa’s hold. Through the reflection of the mirror, Aizawa could see that the boy was hard, cock straining and tenting the much too little fabric.
Aizawa chuckled, brushing his fingers along Bakugo’s length, making him shiver and gasp. “Ahh..are you gonna fuck me or what…” Aizawa hummed, “trust me, I want to. But with no lube?”
“I’m sure you’ll figure something out….pleaseeee…” Bakugo’s voice pitched high at the plea, echoing around the room. Aizawa went for Bakugo’s throat, squeezing hard. “You’ll have to be quiet. Can you even manage that?”
Bakugo whined, nodding his head as best as he could. Aizawa didn’t really believe in Bakugo’s abilities, but his wanting for the boy was too high. His reason and better judgment no where to be found.
Without warning Aizawa grabbed Bakugo’s wrists, flipping their positions and pushed him with enough force that he stumbled backwards until his legs hit the bed and was forced to fall back onto the mattress.
Aizawa swiftly joined Bakugo, hauling him up the bed with ease, hovering over the boy, Aizawa connected their lips in a heated hungry kiss.
Bakugo’s hands clawed at Aizawa’s back, pulling him even closer, marking the skin. Aizawa hissed at the pain but welcomed the closeness, grinding their bodies together, making them shiver in unison.
Bakugo’s heavy breathing soon turned into panting with high pitched moans slipping out here and there as Aizawa continued his onslaught. Kissing the boy’s neck, fondling his pecks, grinding their hard lengths together. Bakugo arched into every touch like he couldn’t get enough. Aizawa himself was getting carried away, caught up in the feeling of Bakugo’s body against his, the sweet smell that seemed to always exude from the boy. Aizawa could continue like this for hours, but doing this was risky, completely irresponsible actually, so he thought he should at least speed things up a little bit.
Without disconnecting their bodies, Aizawa reached for Bakugo’s shorts, pulling them down his thighs, off his legs and threw them to the floor. Deciding he wanted Bakugo fully naked, Aizawa also pulled his shirt up over his head, discarding that too.
Now Bakugo was beneath him, naked and flushed, chest heaving with every breath, cock leaking into his stomach. Aizawa couldn’t help but rack his eyes over the expanse of exposed skin. He really was very beautiful. A wet dream really.
A wave of mixed emotions crashed over Aizawa as he stared down at his student, arousal, pride, possessiveness. But Aizawa had no reason to feel prideful, sure he helped train the boy, but it was thanks to Bakugo’s own hard work and strict routine that his body was this phenomenal. And Aizawa certainly had no claim over Bakugo, but a part of him wished he did. Well, they did both promise not to sleep with anyone else, but that was just for the duration of this arrangement, and how long could this really go on for? Until Bakugo graduates? Aizawa’s stomach twisted in displeasure. That’s less than two years away. Less than two years until Bakugo is released into the world, the adult world. Where there would be endless amounts of men lining the streets to sleep with him. And given Bakugo’s predicament, he’d probably accept a decent number of them. Aizawa didn’t even like the mere thought of that.
“You just gonna stare at me all night or what?” Bakugo’s voice penetrated Aizawa’s haze, with the sound of impatience but also a lacing of amusement.
Aizawa unclenched his jaw which he hadn’t even realise had tightened, huffing a breath. “I could…” Aizawa lowered himself back down, mumbling. Taking a nipple in his mouth, he scrapped his teeth against the sensitive bud, causing Bakugo to moan and arch his back. “But I know you wouldn’t last two minutes until you’d be begging me to touch you.”
Bakugo sucked in a shaky breath, before huffing out a conceited laugh. “Oh yeah? Well I don’t think you’re doing much better than me, sensei~” Bakugo had reached down, palming Aizawa’s length through his thin pants, curling his fingers around it. Aizawa groaned at the friction, his cock throbbing in Bakugo’s hand. “I didn’t even ask for this. But here we are. About to fuck. Because you want to. Even though your other students are just on the other sides of these walls. So who’s really the one begging for it? Hmm, sensei?~”
Aizawa’s gut was hit with a pang of guilt and annoyance. Because it was true. Bakugo was right, this wouldn’t be happening right now if he had more self control. And usually he did. But lately….it wasn’t so easy. Bakugo made it so difficult.
Sitting up straight and removing himself from Bakugo, Aizawa stared down at his student. “Turn around and get on your hands and knees.” Bakugo’s face flashed with confusion. “Now Katsuki.” Aizawa kept his voice stern, commanding.
Even though Bakugo was right, and Aizawa should be stopping this right here and now, he didn’t want to. Ignoring his guilt, he chose to focus on his desires. Which were telling him to sink himself into the boy’s hole as soon as possible.
Bakugo looked somewhat sceptical, but soon did as he was told, presenting himself to Aizawa, but his body shook.
Aizawa squeezed one cheek roughly, thumb gliding down towards Bakugo’s tight hole. “You’re..you’re not just gonna shove it in dry right?” Bakugo’s voice trembled slightly, clearly confused and concerned as to what Aizawa was up to. Aizawa hummed, shifting his weight on the bed. “Wait-“ Bakugo tried to squirm away, but Aizawa tightened his grip, his other hand finding Bakugo’s upper thigh, holding him in place.
“Oi. Wait! You can’t just-ahhh!” Ignoring Bakugo’s pleas, Aizawa leaned forward, swiping his tongue over the boy’s hole.
“Wait- what are you-mmmmh” Bakugo struggled against Aizawa’s hold, craning his neck to get a look. But Aizawa continued to ignore him, wetting and massaging the tight rim with him tongue until it was pliant enough the breach.
Bakugo moaned into the pillow underneath his head, body shaking, his protesting stopped.
Aizawa wasn’t expecting Bakugo to be so confused or shocked at this development, how else was he meant to get the boy’s hole wet? Even with this, it was surely going to be a struggle.
Gathering as much spit as he could, Aizawa practically drooled against Bakugo’s hole, pushing the wetness in with his tongue. It had been a long time since Aizawa did anything like this, but he wasn’t complaining. Somehow, even this part of Bakugo tasted sweet and if the boy’s whimpers were anything to go by, he was clearly enjoying it. Aizawa’s cock throbbed with need, in a position like this he wasn’t getting any type of friction, his large cock hanging uselessly between his legs. This would have to hurry up.
Joining in on the action, Aizawa’s thumb rubbed and tugged at the puffy rim, pushing in to the hot tightness, Bakugo mewled, pushing himself backwards in to Aizawa’s touch.
Fortunately, this was a hole that was quite used to being stretched open, so even without any lube Aizawa was soon able to withdraw his thumb and replace it with two fingers.
Letting his tongue do most the work, Aizawa used the two fingers to scissor the tight space apart, thrusting and curling his tongue in, he added more and more spit, until Bakugo was practically dripping wet.
Aizawa leaned back, admiring his work, testing the give with his fingers. Bakugo’s hole fluttered at the touch. This would probably be good enough. But maybe an extra precaution wouldn’t hurt.
Withdrawing his fingers, Aizawa spoke. “Turn around.”
Bakugo drew up on shaky arms, turning his naked body over slowly. His face was completely flushed, lips red from biting them. Aizawa felt his own eyes darken. Bakugo looked so good like this.
“Suck it.” Aizawa pulled his pants down enough to free himself, cock springing from the confines angry and leaking.
Bakugo looked dazed as he righted his position, leaning forward he quickly took Aizawa into his mouth, briefly massaging the head of his cock with his tongue before taking it down his wet throat.
Aizawa groaned, hand snapping up to hold Bakugo’s head in place, keeping himself fully sheathed he rocked his hips in shallow thrusts. “Fuck. That’s it. Get it nice and wet.”
As Aizawa stared down at his cock disappearing from view, Bakugo looked up through wet eyelashes. Catching the movement, Aizawa locked their eyes.
Instantly, that feeling of possessiveness began to rise within him again. An image of Bakugo on his knees like this for Inasa, for anyone else, flickered in Aizawa’s mind. It was an awful feeling really. Like anger, it was compulsive and hard to ignore. But Aizawa was an adult. He should be able to control or at least ignore it. But in all honesty, he hadn’t had much practice. He got annoyed often sure, but the feeling of true anger wasn’t that frequent for him, and possessiveness over another person? Definitely not something he had ever experienced before. This was a new experience, one he didn’t particularly like.
Bakugo hummed then, drawing Aizawa’s attention back to the fact that he currently had his cock buried deep down his student’s throat. The vibrations made him shiver and he felt close to coming, despite only just putting it in this warmth moments ago. The glassy red eyes stared up at him like the boy was questioning the stillness. Aizawa let go of his hold on Bakugo’s head and let out a shaky breath. “Just…get it wet.” He’d have to think over this problem of his at a later time.
Bakugo hummed again in understanding. Pulling off slowly, he mouthed at the swollen head and licked and sucked down the shaft, leaving a glistening sheen of spit every time he pulled back.
“That’s enough. Lay on your side.” Aizawa took himself in his hand, pushing Bakugo away gently.
“…on my side?” Bakugo relaxed against the pillows, wiping the spit away from his mouth with the back of his hand. Aizawa hummed, positioning himself to Bakugo’s left, as he too rested against the pillows. Turning to his side, Aizawa pulled Bakugo close, man handling him into the position he wanted.
“Like this.” Aizawa murmured against Bakugo’s ear, pushing his chest against the boy’s back. Aizawa’s hand trailed light touches across Bakugo’s side, down his torso, over his hip, halfway down his thigh and then pushed it up so it bent at the knee, keeping the bottom leg relatively straight.
Aizawa mouthed at the skin of Bakugo’s neck, as he took himself in his hand, nudging it against the tight rim. “Have you even done it like this?”
Bakugo shook his head, hands gripping the sheets and the pillow underneath his blonde hair.
“Hmmm, I’m sure you’ll like it.” Aizawa felt giddy for a moment, happy to be doing something Bakugo had never experienced before.
Aizawa rubbed his leaking head over Bakugo’s entrance, further wetting the area and teasing his fluttering hole.
“Mmm…just do it already…” Bakugo whined against the pillow in an obvious attempt to keep his voice down. Aizawa hummed, but didn’t push in.
“Are you sure? You usually prepare yourself so well for me….compared to that, I’m afraid this will at least sting a bit.” Aizawa spoke in a teasing tone, but a part of him was concerned that this was about to be painful, for the both of them. Bakugo grunted in annoyance, “I’ll be fucking fine. You practically spat inside me,” his voice rising.
Aizawa huffed a laugh. “Fine. If you say so.” Without any more warning than that, Aizawa pushed in, popping his throbbing head past the swollen rim. It was tight. Tighter than usual. But not so tight that it was impossible. Cutting off the moan in his throat, Aizawa thrusted forward, sinking into the heat until he was balls deep. Bakugo screamed.
Quickly, and with a little too much force, Aizawa wound his left arm underneath Bakugo’s head and slapped his palm over the boy’s mouth. “Quiet.” He growled lowly in Bakugo’s ear. They were so dead if anyone came knocking at their door.
Bakugo whimpered, nodding his head. But Aizawa could see tears forming in red eyes. “Does it hurt?” He asked with genuine concern. It felt fine for Aizawa, better than fine. Hot, tight, and plenty wet enough. However he wasn’t the one being thrusted into with not enough prep.
Bakugo inhaled a shaky breath through his nose but shook his head. “Are you sure? Don’t lie to me.”
Bakugo opened his mouth, mumbling against Aizawa’s palm. “Doesn’t hurt….feels good…sensei….”
Aizawa’s breath caught in his throat. Bakugo was crying because it…felt good? Pulling out the slightest amount, Aizawa pushed back in slowly, rutting his hips against Bakugo’s ass, testing the give as he watched the boy’s face for any signs of pain.
Tears overflowed from red eyes but Bakugo’s cheeks were flushed and his expression blissed out as he moaned against Aizawa’s hand.
Aizawa chuckled, of course the boy was totally fine, he was probably getting off on not being prepared properly, treated roughly. Aizawa wanted nothing more right now than to fuck him hard and senseless, but they had to stay quiet. So he was going to have to settle for something a little more tame.
Holding on to Bakugo’s hip, while keeping his other hand firmly pressed to the boy’s mouth, Aizawa began to move. He pulled out to the tip, then pushed back in slowly, milking the moment his head pressed up against Bakugo’s tight walls.
In an attempt to keep himself quiet, Aizawa busied himself at Bakugo’s neck, licking, kissing, biting at the soft skin, tongue tracing over the fading bruises he left there mere nights ago.
He had been feeling guilty over the sight of these bruises, scared of the extent and the capabilities of the dominating side of his personality. But right now, the bruises seemed to egg him on. They were a reminder that he was the one that left them, that he was the only one who could leave something like that on Bakugo’s body now. Unlike before. The first night they had sex, there were marks from someone else littering the boy’s body. Aizawa hadn’t liked that sight then, and if he saw something like that again now, he would be furious.
As Aizawa continued to roll his hips against Bakugo’s ass, he started to move his hand from gripping Bakugo’s hip; with the intention to grope his chest. But as he passed over the boy’s toned stomach, he felt something, something moving.
Aizawa groaned against Bakugo’s neck as his cock pulsated, balls pulling tight. He could feel himself moving inside of Bakugo. He could feel the outline of his cock through Bakugo’s stomach. Fuck. Aizawa screwed his eyes tight shut, almost loosing himself. He stopped moving, not wanting to cum just yet.
Bakugo moaned in protest, pushing his hips back against Aizawa, trying to get some friction.
Aizawa huffed against Bakugo’s neck, “stop that. Do you want it to be over already, hmm?” He pushed his hand harder into Bakugo’s stomach in an attempt to stop him from moving, but all it did was apply more pressure, more pleasure, to his throbbing cock. But Bakugo seemed to get the message, his squirming coming to a halt.
After a few deep breathes to steady himself, Aizawa spoke, “give me your hand.”
Bakugo made a slight noise of confusion but moved his right hand down to where Aizawa’s rested.
When the soft skin of Bakugo’s palm brushed over the top of Aizawa’s hand, he reversed their positions. Grabbing Bakugo’s hand in his, Aizawa pushed the boy’s palm against his own stomach. “Feel here,” grumbling against his ear, Aizawa began to move once more.
—
“Oh fuck.” Bakugo felt like he was going to pass out.
“Can you feel it?” Aizawa murmured close to Bakugo’s ear. Yes he could fucking feel it. He could feel his teacher’s cock carving out his insides, and it felt fucking amazing.
Every single thrust, while slow, dragged over Bakugo’s prostate, sending ripples of pleasure over the entirety of his body. And now this? Feeling it from the outside too? It made him dizzy. But it wasn’t just that. It was Aizawa. Bakugo couldn’t even believe that they were actually having sex right now. After what happened earlier, he assumed his teacher was going to ignore him. Act as if they really were just student and teacher. But Aizawa fucking ate him out?! He got to sucks his cock again. And now they were fucking?! Bakugo was fucking elated to say the least.
Suddenly Aizawa intensified his thrusting, not quicker, but harder, all while still holding Bakugo’s hand to his stomach. The motions shifted his body, causing his leaking cock to rub against the sheets. “Mmm…ahhh….fuck.” Aizawa’s hand had loosened over his mouth, but as Bakugo let out his moans, it returned firmly.
Bakugo wasn’t going to last much longer. Everything was so hot, his teacher was everywhere, and the heat was pooling in his stomach. He whined against Aizawa’s hand, tried to mutter words of his oncoming orgasm, but his teacher only increased the pressure of his hold, shushing him with a whisper.
And that was it. Bakugo’s body surged with pleasure. Originating from deep inside, it cascaded over him and his vision went white, the ringing in his ears drowning out the sounds of Aizawa’s grunts.
Once Bakugo came to, Aizawa was still, breathing heavily against the back of his neck. The warm breath somehow comforting and ticklish at the same time. They laid in that almost silence for a while, Bakugo’s eyes beginning to flutter shut just before Aizawa spoke with a grumble. “We should clean up.” But the man made no attempt to move. Rather, still buried deep inside, he tightened the hold with his right arm, pulling Bakugo even closer.
Bakugo sunk into the warmth, eyes slipping closed again with ease. “Don’t wanna. Too tired.”
Aizawa hummed in agreement and stayed still for a while longer. But eventually, he began to move, stirring Bakugo from his sleepy daze. Aizawa was careful, pulling out gently, he moved with slow precision as to not disturb Bakugo too much and left him on the bed. “You wait here then.”
For a fleeting moment Bakugo thought that Aizawa was going to go clean himself up and then crawl into the other bed, leaving him dirty and laying on top of the sheets. A sting entered his heart. But before long, Aizawa returned with a warm hand towel.
Sitting on the edge of the bed, Aizawa leaned over Bakugo’s body, wiping him down with continued gentleness. But as Bakugo kept his tired eyes on his teacher’s face, he couldn’t say the expression there matched. It was stern and concerned, his gaze distant.
Once again, Aizawa looked regretful. And it made Bakugo feel like shit. He didn’t know what to do. Or what to say. The situation was too delicate for someone so forward and brazen like him. He had tried apologising last time, but that was a complete bust. So…maybe the opposite would work?
“Sensei…” Bakugo murmured the beginning of his plan and paused. Aizawa hummed in questioning, his dark eyes finding Bakugo’s. With a tired but sultry voice, Bakugo continued, “that was fucking amazing.”
Aizawa choked. Like literally choked. On his own breath or his spit, Bakugo did not know. But his expression had changed. Eyes wider and more present, staring down at Bakugo before he quickly looked away. After a short moment, Aizawa huffed a sigh and shook his head, “I’ll buy some cream tomorrow.” Bakugo swore he saw a slight curl to his teacher’s lips. Well, that definitely went better than saying he was sorry. Relief, along with something else, something warmer, flooded his being.
“I don’t need cream. I’m fine.” Bakugo mumbled out his reply, not really concerned with whether he did need cream or not. He was feeling good, and wanted to sleep before it slipped away. “I’m tired.”
Aizawa nodded, standing up. His eyes roamed the floor before reaching down to pick up what ever he was looking for. Bakugo’s shorts landed next to him on the bed with a swing of Aizawa’s arm.
Bakugo huffed, moving slowly he pulled them up over his legs, muscles a little sore from the days activities.
As Aizawa seemingly rummaged through his bag, without much thought Bakugo pulled back the sheets and settled into the bed, his eyes fluttering shut instantly. As the sounds of rummaging ceased, he heard a loud sigh. Only then did he really consider the situation. Bakugo had left his stuff all over the other bed and climbed into Aizawa’s. The beds were only king singles. Maybe sleeping like this, sleeping so close, was too much to ask. But, Bakugo didn’t want to move. He didn’t want to sleep alone. Even if the beds were a mere two meters apart.
Bakugo kept his eyes closed but his heart began to race as he anticipated Aizawa kicking him out.
The seconds drew on and his heart grew faster in the silence of the room.
But then a subtle click echoed in Bakugo’s ears. He opened his eyes to find nothing but darkness. Aizawa had turned the light off.
Bakugo felt the bed shift, the sheets pulled at, and a warm body slip into the narrow space behind him. His heart slowed in relief then instantly fastened again, the closeness making him nervous.
He stayed as still as a log, not knowing what he should do, how he should act. Do they just go to sleep like this? Slightly apart and uncomfortable from the lack of space? Do they touch? Do they cuddle? Bakugo didn’t know.
But then the choice was made for him. Tentatively, Aizawa moved closer, the pillow under Bakugo’s head moved and a strong arm snaked around his torso pulling him in, their new found position mirroring the one from earlier.
Bakugo could feel the rise and fall of Aizawa’s chest against his back, the faint but steady beating of his heart. He had never been held like this. But it was nice. Comforting. He felt safe. And more tired than ever.
Bakugo relaxed into the hold, melting himself against Aizawa’s body, feeling quite content, he was more than ready to sleep. “Night…sensei…”
Eyes falling closed, Bakugo’s mind began to slip from consciousness. But not before he caught his teacher’s words. Deep, but quiet, “goodnight Katsuki.”
