Chapter Text
It all started when Shouto noticed Bakugou’s not so little crush on Izuku.
Shouto and Izuku have been dating for around a year and a half. They had always been good friends, even from the beginning of first year. Izuku had a way about him, of breaking down someone’s defenses and getting to the root of who they are. Shouto had never had someone truly see him the way that Izuku did, especially so shortly after meeting.
It made complete sense how their friendship could easily give way to feelings, at least on Shouto’s side. Now Izuku actually returning his feelings was a bit more of a surprise.
It didn’t just happen one day, there was no big or dramatic moment. It sort of just evolved over time. In the beginning, he started feeling butterflies around Izuku, during completely normal moments. When they sat together at lunch, when Shouto noticed Izuku in crowded spaces, or when Izuku and him would stay up late studying in each other’s rooms. In the late hours of the night, when everything is quieter, that’s when you see things with much more clarity.
It became overwhelmingly difficult to ignore the nagging voice in Shouto’s head those nights, telling him to kiss Izuku. He could easily brush that other stuff off as being excited to have such a close friend, but that could not be overlooked.
So the very next day, nearing the end of their first year, Shouto told Izuku exactly how he felt. It was incredibly worth it obviously, if nothing else then for the sole reason of getting to see Izuku sputter and fluster over his blunt declaration.
In all honesty, he didn’t expect Izuku to kiss him afterwards. He only confessed his feelings because he didn’t know what to do with them, and Izuku was always the one he turned to in the past for help sorting out his feelings.
It was such a special moment for Shouto and he looked back on it with much fondness. How could he not? For it was the first time he ever felt romantic love for another person. There was no denying the fact that Shouto Todoroki was in love with Izuku Midoriya.
They announced the new developments in their relationship in multiple instances throughout that same day. Tenya and Momo reacted fairly positively when he told them. Momo was not surprised in the slightest by the news, and Tenya attempted to go into a lecture about using protection, which he promptly cut off.
When they told Uraraka, Tsu, and most of the other girls, Shouto had to plug his ears in order to protect his eardrums from the subsequent cacophony of high pitched screaming and cooing. Most of the rest of the class found out through the grape vine. Everyone took it mostly well, with reactions ranging from overwhelmingly positive to apathetic. Except for Bakugou.
Shouto overheard part of the conversation between Izuku and Bakugou when his green haired boyfriend told his blonde best friend. He didn’t mean to eavesdrop like a creep around the corner, he just heard his boyfriend’s voice and gravitated to the sound naturally. As he got closer, although it was muffled, Shouto realized that he did not sound normal. The voice which was usually sweet and gentle was now shaking and strained. Then came an equally muffled stern and raspy voice.
He peered around the corner and took in the scene. They were hovering in the hallway of the dorm lobby.
“Don’t say things like that, Kacchan!” Izuku shifted back and forth on his feet uncomfortably.
“What? It’s just some friendly advice. I just wanna make sure poor, innocent little Deku doesn’t bite off more than he can chew,” Bakugou’s tone was heavy with implication.
“I can handle it just fine, thank you very much!” At that point, Shouto rounded the corner into view of the two boys, who immediately looked his way at the movement.
Izuku blushed a deep red when he laid eyes on Shouto and Bakugou smirked mischievously at the sight of him.
“Just try not to leave any lasting damage,” Bakugou began while intensely staring at Shouto, “If your fun interferes with training cause you were too rough with him, just know I’ll be pissed at you IcyHot.”
And with that, Bakugou walked away, leaving the couple to gape at each other.
“What was that about?” Shouto closed the distance with a raised brow. He coated his right hand in a thin layer of ice and pressed his palm to his flustered boyfriend’s forehead in a gentle grounding gesture to cool him down.
“Kacchan’s just teasing,” Izuku brushed off with a shake of his head.
At the time, Shouto did in fact take it at face value. But it was far from the last time Bakugou would regard Izuku in such a taunting manner.
The second instance took place when they were studying. Kirishima needed help studying for midterms so somehow, a large group of the boys all found themselves in Izuku’s room. After a few hours, the goofing off to studying ratio was about six to one, with Shinsou being the only one who was doing anything that even slightly resembled studying.
Everyone was ribbing Izuku for his excess of hero memorabilia, and specifically his Present Mic mug. Even Shouto would admit that it was objectively cringey. It depicted a side view of Mic’s face with a big goofy smile. His blonde hair swooped back and off into the handle to make it look like the handle was his hair.
Kirishima and Sero were crying from laughter, while Izuku was yanking it harshly out of Kirishima’s grasp and stuffing it into his closet shamefully. Opening the closet was clearly the wrong thing to do, because it only encouraged Bakugou to go rifling through the shirts hanging up, as if he was searching for something.
Meanwhile Bakugou was in the process of briefing through Izuku‘s closet. Shouto was half paying attention to the conversation, and half watching Bakugou take his shirt off and casually replace it with one of Izuku muscle tops.
“Kacchan, what are you doing with my shirt?”
Bakugou made a show of animatedly sniffing the collar of the shirt and rolling his eyes back before speaking.
“Smells like you,” he said with a smirk.
Once again, Izuku went beet red and shoved his friend in his shoulder while scolding him for being a creep.
“Bro! What?” Kirishima and Sero let out a hearty laugh, catching the tail end of the interaction. Even Shinsou cracked a smile.
Then he threw another shirt at his friends. It happened to be a Midnight shirt which depicted her silhouette in her debut costume, which made it appear as though the person wearing the shirt was Midnight wearing the costume. It was quite comical, and everyone seemingly forgot about the previous interaction and started making fun of Izuku again.
Well, everyone except Shouto forgot about it. He was carefully observing. It was clear that it was a joke, but Shouto found it a little bit strange. It didn’t genuinely bother him though, so he simply just filed the knowledge away for later.
The next time it happened was at school. Shouto and Izuku were heading to the table where they always ate lunch with Tenya and Uraraka with their lunch trays in tow. They passed by Bakugou who was heading to his own lunch table with a stack of napkins in hand.
Izuku was busy telling Shouto about a phone call he’d had earlier that day with his mother, so he didn’t notice Bakugou walking by. But Shouto was able to see Bakugou’s hand dart out and brush Izuku’s waist as he passed. Both Izuku and Shouto turned around to look at Bakugou, but he just kept walking without even so much as sparing them a glance. Almost like it was an accident. But Shouto knew better. And if Izuku’s reddening cheeks were anything to judge by, he knew it too.
“What’s up with him lately?” Shouto asked his boyfriend.
“Oh, that? Kacchan thinks it’s funny to mess with me like that,” he rolled his eyes, and then they widened with realization, “But don’t worry about it Shouto, he’s straight! He definitely doesn’t mean anything by it! He’s just being an asshole because he knows it embarrasses me.”
Honestly, Shouto found Izuku’s flustered reactions incredibly cute, but that was because he was literally dating him. He didn’t really see what was so funny about it, but there were a lot of things about Bakugou that Shouto didn’t understand. He supposed he could add the blonde’s twisted sense of humor to the list.
But that was the thing that didn’t sit right with him. Bakugou was definitely pushing the envelope with his frequent teasing, but to what end was where it became less clear. It continued this way for many months. Bakugou would often say or do something racy, and Izuku would sputter and blush in embarrassment.
And over that time, the teasing got worse. It got to the point where Bakugou started blatantly coming onto Izuku.
One such instance happened at 11pm on a Saturday night. Shouto and Izuku were cuddling on Shouto’s futon. Izuku was lying on Shouto’s chest and their legs were tangled. Shouto absentmindedly stroked the hair at Izuku’s nape and watched over his shoulder as Izuku scrolled on social media.
Then a notification banner popped up at the top of Izuku’s screen. It was from Bakugou, and the out of pocket message just read wish you were here <3.
Izuku scoffed when he read the message, and sent a simple thumbs down emoji in response and went right back to scrolling. He made those kinds of comments all the time. But in Bakugou’s defense, he also did it to some of his other friends too. It just so happened that Izuku mainly was the object of the blonde’s ministrations. And, not to mention the fact that he was allegedly straight.
Plus, Izuku never took any of it seriously, and that sentiment was completely genuine. Shouto could tell there was nothing suspicious going on because Izuku was an honest to god shit liar. He was never able to keep anything from him, and especially not something that big.
The fact of the matter was he trusted Izuku completely. But that didn’t mean Izuku completely understood his best friend’s antics either.
His gut was telling him that it wasn’t really a joke. But Bakugou was smart, because if that was the case and someone did notice, the blonde was easily able to hide under the guise of it being a joke. Shouto’s suspicions became even stronger over time. But of course, he had no proof so he wasn’t sure what to do about it.
The weirdest part was that he wasn’t jealous, not even a little bit. He knew that Izuku truly loved him, so there was no reason to take any of it to heart. But he was extremely curious about Bakugou’s intentions.
So eventually, Shouto attempted to poke the bear a bit.
One evening, Shouto and Izuku were preparing Gyudon for dinner for them and whoever wanted some, while Bakugou sat at the breakfast bar.
“Kacchan, can you taste the beef? I’m not sure if it’s seasoned enough,” Izuku held up a piece of beef with his chopstick and brought it to Bakugo’s lips. While he was chewing, Shouto saw the opportunity for what it was, and decided to test his theory.
“Yeah, Bakugou, what do you think of Izuku‘s beef?”
Bakugou immediately smiled, tipped his head back, and then let out a very dramatic moan.
“It tastes like I’m about to cream my pants,” he said with his mouth full.
“Ugh, Shouto do not encourage him, please!” Izuku scolded, hiding his face practically inside of the cooking pan.
“Come on Deku, don’t squash his dreams,” Bakugou quipped.
“Bakugou, if you want my boyfriend that bad, you don’t have to hide behind a joke,” Shouto released a measured laugh to play it off if need be. He studied Bakugou’s face for any hesitation, look of panic at being boldly called out, really any kind of reaction that would give Shouto’s suspicions some ground to stand on. But Bakugou didn’t give an inch, just looked him in the eye and then barked out a laugh.
“Well, it seems like your little Shouto isn’t as much of a stick in the mud like we all thought,” Bakugou said to Izuku.
“Alright, uh huh, now enough of that or you get no Gyudon,” Izuku pointed a wooden spoon at Bakugou threateningly.
Bakugou did shut his mouth but kept the shit eating grin. Well that revealed glorious nothing. Damn that Bakugou.
From that point on is when everything started getting more complicated. Shouto became much more aware of Bakugou’s presence in every room, closely watching the blonde’s every move. It was purely analytical, at least at first.
He kept track of Bakugou every time he was around Izuku. He watched when Bakugou chose to speak, how close he stood to Izuku, the tone he used when speaking normally, and when he was making his ‘jokes’. He noticed that Bakugou had a tendency to divert the attention off of himself afterwards. While everyone else stopped paying attention to Bakugou, Shouto kept his eyes trained on the blonde, looking for any sign of something. But he never slipped up, so he just kept watching.
Shouto never spent so much time looking at Bakugou before. All the time spent looking at the blonde revealed things he had never noticed before.
Bakugou always chewed on his bottom lip when he was stressed, and when his hair was in his face, he would always blow a gust of air up at the offending strands to clear them from his eyes rather than just using his hands to move it.
Something else he discovered was that he was also almost as big of a nerd as Izuku, though he hid it well. He was only able to notice the gleam in his eye when All Might walked into the room because he had seen that same look a million times in Izuku.
When Izuku wasn’t around, Bakugou had a mostly normal sense of humor. He was also a lot quieter than he was in Izuku‘s presence.
Despite this, however, Bakugou actually bragged quite a lot about sexual exploits. And it wasn’t the same as his over the top moaning and teasing that he did to bother Izuku. It was more honest, less teasing but a little more explicit. For someone who had allegedly never been in a relationship, this was curious. He couldn’t help but wonder where Bakugou was going to have so much sex with multiple people all the time. What he found the most noteworthy however was that Bakugou only seemed to say those things when Izuku wasn’t around.
In Shouto’s mind, that was a huge piece of evidence in favor of his working theory. But it still wasn’t enough. And then one day he finally slipped up. It was in the middle of the day, so people in the dorms were buzzing around and active, but the vibe was still relaxed enough that the noise just settled into the background. A bunch of them were in the common room including Shouto, Izuku and Bakugou.
Shouto was sitting at the table across the room doing homework by himself. But after thirty minutes of solving differential equations, Shouto decided to take a break in favor of silently watching his pretty boyfriend. Izuku sat on the couch with his notebook, feet flat on the cushions as he used his thighs as a table, muttering and writing at the same time. Cute, he thought. He always did find it adorable when Izuku went off into his own world, so immersed in what he was doing that he just couldn’t help that his thoughts would spill out sometimes. But it seemed like he wasn’t the only one who thought so.
Bakugou was sitting nearby on the opposite couch, not really engaging with Izuku. In fact, Bakugou wasn’t doing much of anything at all. He hadn’t said anything in several minutes, he wasn’t doing homework, or even on his phone which was sitting face down on the coffee table in front of him. But what he was doing was stealing glances at Izuku every few seconds.
Shouto wasn’t even trying to watch him that time, but the way Bakugou quickly looked away every time Izuku would shift and then glancing at him again was extremely suspicious. It was basically the same as having flashing lights, sirens, and a big sign over his head that practically screamed I like Izuku.
“Kacchan wait, this strategy I wrote down, can you tell me if it makes sense?” Izuku said suddenly without taking his eyes off the page.
“Tch, it’s probably shit,” Bakugou taunted, but he reacted instantly and stood up all the same, moving closer and leaning over Izuku’s shoulder to look at the notebook.
Bakugou’s wrist leaned against the back of the couch, fingers slightly brushing against his shoulder. He leaned in even closer as Izuku started to explain what he had been writing down to Bakugou. Then Bakugou turned to look at Izuku with an interesting look in his eyes, a flash of vulnerability flitted across his features and his face leaned in far too close than would seem appropriate, as if he couldn’t help but get closer to Izuku. But it was fleeting, because a moment later the blonde noticed Shouto watching them.
His red eyes dilated and Shouto noticed it even from across the room. Shouto did not react, but he did not look away either. And because of it he saw the moment Bakugou’s wall went back up. The blonde smirked at Shouto and then fully wrapped his arm around Izuku’s shoulder, sitting next to him on the couch and looking back at Izuku.
“What do you think?” Izuku finished explaining, finally looking at Bakugou for the first time in the conversation.
“I think it’s so fucking good,” Bakugou rolled his eyes and tipped his head back, speaking in a purposefully lustful voice. Izuku paused, and his shoulder dropped as he realized that Bakugou was being stupid again.
“Can you be serious, please? I actually wanna know what you think,” Izuku huffed.
“Yeah, yeah,” Bakugou relented, regarding Shouto with another quick glare before moving his arm and actually paying attention to Izuku’s notebook, giving his thoughts on Izuku’s strategy. Then he straightened and pulled away, but before he fully stepped back he spoke again.
“Fix it and show me again,” Bakugou directed. Izuku lit up and smiled brightly at the blonde.
“Yeah, okay!” Izuku said. Then Bakugou turned away and returned to the couch he had been sitting on like the whole thing didn’t happen at all.
And that was it. That moment, the look he gave Izuku was exactly what Shouto had been waiting for. That inexcusable shred of proof, or at least enough probable cause for Shouto to be fairly certain that Bakugou did in fact like Izuku more than friends.
After that, the way Shouto saw Bakugou and Izuku’s friendship completely changed. Every interaction between them was then interpreted through the lens of forlorn pining on the blonde’s part.
But the weird thing was that it still didn’t make him feel jealous. Actually, part of him felt a rush because now he actually had something on Bakugou. He knew his secret, the one that he hid so well from everyone else, including Izuku himself.
The first time Shouto was alone with Bakugou after his realization was after a few days had passed. It was late, and everyone in the dorm was sleeping so it was quiet and tranquil, but unfortunately, Shouto just wasn’t tired. That happened to him sometimes, where he had a hard time falling asleep, and a lot of the time that resulted in hours of tossing and turning only to get little to no sleep the whole night. Over the years, he’d learned to stop even trying to stay in bed when he felt like that, and that’s what led him to the kitchen that night to make a cup of tea.
He was at the counter, actively pouring hot water into his cup to let the tea bag steep, when he heard footsteps approaching from behind. Shouto didn’t know who it was, but he didn’t turn around to see either. The footsteps stopped a few feet behind him, and Shouto was able to smell the faint trace of sweet musk that indicated whose eyes were currently burning a hole in the back of his head.
“What are you doing up so late?” Shouto asked, his voice raspy from hours of inactivity.
“Late? Do you have any idea what time it is IcyHot?”
Shouto turned around to find Bakugou standing there gawking at him. His hair was a mess, his face was tinted red with a thin layer of moisture highlighting the apples of his cheeks as well as the sculpted muscles of his arms. He was slightly out of breath and it was clear that he had just returned from a workout.
He walked closer and right into Shouto’s space, practically trapping him against the counter. He stared Shouto directly in the eyes in a clear challenge. The ghost of a smirk could be seen forming on his lips before he reached up past Shouto’s head to grab a glass from the cabinet, even though there was plenty of room to walk around him.
More of the sweet scent of Bakugou’s musk permeated through the air as Bakugou turned towards the sink and filled the glass with water which he downed in two greedy gulps. He filled the glass again, making eye contact with Shouto as he drank the second one, slower that time. His throat contracted as he swallowed. Then, he slammed the glass down on the counter with more force than necessary and let out a contented and obnoxious sigh. He carefully placed the glass in the sink and left the kitchen without another word.
After he left, Shouto quickly gulped down his tea instead of slowly enjoying it as he normally would, feeling the hot liquid burn his throat on the way down. With a sudden burst of energy that should not be befitting of someone who just drank chamomile tea, Shouto found himself outside of Izuku’s room carefully tiptoeing inside without waking him.
He climbed into bed behind his boyfriend and pressed his body roughly into Shouto’s front. The action slightly stirred Izuku from his deep slumber with a sleepy noise that lit Shouto’s body on fire. He started placing slow, wet kisses against the back of Izuku’s neck and the sleepy noises turned into pleasured whines.
“Ah, Shouto!” Izuku exclaimed, his hand reaching back to bury into Shouto’s hair and pull his mouth impossibly closer. Shouto groaned at the sound, his cock twitching to life.
Izuku rolled over to face Shouto, eyes still closed as their lips met in a filthy, sloppy kiss. Izuku’s leg slid over to straddle his hips, purposefully brushing up against Shouto’s half hard cock as he did so. Shouto licked his lips as he stared up at his gorgeous boyfriend in awe, who was now rocking his ass onto Shouto’s clothed groin like he was riding him.
“Good morning to you too,” Izuku smiled lovingly, his sweet expression in complete contrast with the filthy way he moved his lower half.
“Come on baby, please I need you,” Shouto begged.
“Mmm,” Izuku licked his lips, the final signs of tiredness finally leaving his eyes and it instead being replaced with pure lust, “yeah?”
Izuku’s hand slid unceremoniously under Shouto’s pajama pants and took a firm hold of his cock. His hand immediately settled into a steady rhythm that had Shouto gasping and bucking his hips wildly.
“God, Shouto, it's so hot to be woken up like this,” the filthy words started to spill from his mouth, “Knowing you’re so horny that you just have to jump into my bed and start kissing me and touching me.”
Shouto hummed, lost in the incredible stimulation made even better by his beading precum slicking the path for his boyfriend’s hand. In all honesty, he felt like he was already going to cum at that rate.
“Wait, slow down, I’m close,” Shouto gritted through clenched teeth.
Izuku didn’t say anything, but did move his hands to firmly massage Shouto’s shoulders and leaned down to kiss him instead. Izuku didn’t let up on the stimulation completely though. He still squirmed and rolled his hips like a whore, transitioning Shouto from a sprint to a steady crawl towards release.
Izuku smiled sweetly like he was completely innocent in the matter and then his tongue was back in his mouth, exploring and prodding insistently and Shouto could hardly keep up. His heart was beating out of his chest from being so turned on.
Izuku was a wet dream in every sense of the word. His sweet exterior was what made him so electric in the bedroom, but he always made a show of putting on that good boy exterior when they fucked so he knew that Izuku did it intentionally to be a tease and a brat. And it tortured Shouto every single time they were intimate.
Izuku continued to lavish the rest of his body with kisses wearing nothing but his tight boxer briefs that accentuated his plump little ass. It was provocatively presented and Shouto was completely spellbound by his lewd posture. He wanted to spread his cheeks and absolutely devour Izuku from the inside out, but he was completely trapped under his green haired boy. Not that Shouto was complaining. But still, his mind started to wander and imagine the moans his tongue would draw out of Izuku.
But the mouth on Shouto’s nipples were feeling way too good to stay lost in his imagination. The teeth clamping down on his little pink buds forced him back to reality because they were not gentle and it hurt. Shouto closed his eyes and enjoyed the sensation. Fuck, there was no place in the world he’d rather be more than right under his perfect boyfriend’s body. But the call of desire for his pleasured cries was strong, so instead his mind automatically added to his current reality through a perverse fantasy.
In his mind’s eye, stray hands would appear from behind Izuku to manhandle his hips into an even more obscene pose. The imaginary figure would spread Izuku’s cheeks and eat him out with no hesitation, eliciting piercing whimpers from Izuku’s throat.
“Fuck,” Shouto groaned when he realized that the real Izuku had pulled his pajamas down to his ankles and began suckling on the tip of his cock.
He closed his eyes again to fully appreciate Izuku’s tongue circling the crown before dipping into his slit. The fantasy man appeared again, still buried between Izuku’s cheeks and his hands would massage Izuku’s hips, pulling them back and forth to tongue fuck Izuku harder. His whines would become even more desperate to the point that he would have to pull off of Shouto’s cock and cry out loudly into the heavy, pheromone thick air.
Then, the fantasy man would emerge from Izuku’s ass and his face became clear. Bakugou’s face would have saliva soaking down his chin and–
Shouto’s eyes flew open and gasped, taken aback by the object of his own sexual fantasy.
“How’s my mouth?” Izuku whispered in a voice oozing with lust, completely oblivious to Shouto’s inner turmoil.
“So perfect,” Shouto groaned loudly because Izuku’s mouth was devilishly talented, and not for any other reason.
Now that he had thought about it once, Shouto’s traitorous mind just started picturing Bakugou again, this time zero to a hundred, totally balls deep inside Izuku’s ass, pounding into him while Izuku would hover on all fours above Shouto. Izuku would be too overwhelmed by the pleasure to focus on Shouto at all.
Izuku would make an array of expressions contorted in various degrees of torment on full display for Shouto’s viewing pleasure.
“Shouto, he– Kacchan’s dick is– I can’t fucking breathe!” He’d exclaim through a series of stuttering cries.
“Shhh, you’re safe, breathe for me Shouto,” the real Izuku muttered, bringing Shouto back to reality as he felt the words on his cock just as much as he’d heard them. He must have said that last part out loud. Oops.
Shouto closed his eyes and was back in his fantasy again where Izuku’s tears would drip from his eyes right onto Shouto’s face, his eyes wide and mouth dropped open in a scream only silenced by Bakugou’s hand wrapped around his neck from behind.
“Cum for me Deku,” Bakugou would growl and Izuku would shoot off strong ropes of milky white release all over Shouto’s stomach and chest.
Shouto opened his eyes just as Izuku finished swallowing the last drop of Shouto’s orgasm. He was out of breath because wow, he had never in his life gotten so lost in a fantasy before.
“You taste good,” Izuku commented with a delighted grin. He spoke conversationally, as if the words spoken were not absolute filth. With a lick of his lips he crawled up and pressed his ear against Shouto’s chest to listen to the throbbing heartbeat just under the surface.
“Hah,” Shouto replied intelligently. He rested his hand on the back of Izuku’s soft pajama t-shirt as he enjoyed the rush of dopamine coursing through his system.
“I’m pleasantly surprised. You don’t usually initiate sex like that, Sho. Like some depraved, desperate whore. What could have put you in a mood like that I wonder?”
Shouto paused at his boyfriend’s words because they made him come to a realization about what he’d actually just experienced.
Shouto had just had a vivid sexual fantasy while getting his dick sucked about Bakugou fucking his boyfriend. And he liked it for god's sake. He liked it enough that he came so hard he literally blacked out for a minute.
“I bet you had a sex dream, hmm?” Izuku bit his lip.
“Ah, you got me,” Shouto lied easily. Something uneasy lurched in Shouto’s stomach.
“I knew it!” Izuku laughed, lifting his head from Shouto’s chest to smile brightly at Shouto with those big, trusting green eyes.
“How about you show me exactly what kind of lecherous thoughts runs through my good boy Shouto’s mind at night?” Izuku was still soft and sweet as he absentmindedly traced the tip of his finger up and down Shouto’s sternum.
Shouto swallowed when his half soft cock spasmed, and of course his insatiable teenage libido had to once again rear its ugly head. Literally.
The next few weeks after that were nothing short of a disaster. When the post nut clarity truly kicked in, Shouto felt like the absolute biggest asshole in the entire world. He was having trouble reckoning with the fact that he was having sexual fantasies about his boyfriend’s best friend.
And it wasn’t just that one time either. He’d be fine if it was just a one off thing, maybe a little disturbed at first but he'd easily allow it to be filed under the ‘things he doesn’t think about’ folder in his mind. But it wasn’t a one time thing. Thoughts of Bakugou pressing Izuku against a wall and kissing him stupid in the hallways of the dorms, thoughts of them getting hot and heavy during training, vivid images of Bakugou fucking Izuku over the desk during class.
It was extremely distracting to say the least. But the worst was when Shouto had those thoughts during sex with Izuku which unfortunately was quickly becoming a common occurrence for him.
And Izuku, his sweet, perfect, trusting Izuku was none the wiser. He felt like an absolute slime ball.
There was one time in particular he could recall where his thoughts became a real problem for him. A whole bunch of their class were at the shopping mall after school one day. Shouto was following Izuku around as he usually did because malls weren’t really of much interest to him. He only went so that he could spend time with his friends, but he himself? He had no interest in buying knickknacks, and he already had plenty of clothes.
But Izuku loved to peruse the stores for things like that. Usually it was stuff related to heroes, like figurines, merch and what not. He was always on the hunt for the newest hero merchandise. Other times he looked for notebooks, running shoes, and clothes for working out.
That day, they had split off from the main group so Izuku could look for an outfit to wear to Shouto’s mother’s birthday dinner the following week. They were going to this nice restaurant downtown and Izuku wanted to look nice. It was cute. Bakugou for some reason had tagged along with them and was currently bickering with Izuku.
“Wait, I just want to check one more store,” Izuku said, already turning and heading in the direction of the next store.
“You’ve said that five fucking times already “ Bakugou complained, clicking his tongue.
“No one said you have to tag along Bakugou,” Shouto pointed out.
“Better shut your mouth before I shut it for you,” the blonde threatened. He tried to look imposing but Shouto had been on the receiving end of that gaze many times before, so it pretty much had no effect on him. Besides, Shouto’s comment completely lacked any real bite.
“Hey, knock it off! If you two make a scene I’ll-”
“What? Punish us?” Bakugou quipped, his trademark coy smirk visible on his face. Izuku went completely red and honestly, Shouto probably did too because it made for an explicit visual that made his stomach do flips.
“Stop being disgusting in public!” Izuku stammered, lowering his voice.
“Oh,” Bakugou lowered his voice to match Izuku’s volume, although it was clearly out of a teasing nature rather than genuine remorse, “so it’s fine if I’m disgusting in private, Deku?”
Bakugou eyed Shouto curiously after that, so he forced his expression to go blank and become unreadable, despite the nasty heat pooling in his groin.
“Fine, that settles it. I won’t make a scene in public but you,” Bakugou pointed rudely right in Izuku’s face, “are going to give us a show when you’re trying on clothes.”
“Freak,” Izuku grumbled, but did not argue further.
When both boys turned away, Shouto did a quick scan to make sure no one was looking and then subtly adjusted his cock so that his sudden and embarrassing boner was not so easily visible.
From that point on, Shouto’s cock practically lived in his waistband any time he was around Izuku and Bakugou together. He pretty much stopped wearing any kind of pants that were too tight or a light color, which unfortunately did not escape the notice of his boyfriend.
“I noticed that you’ve been wearing sweatpants a lot, Shouto. Is everything okay?” Izuku spoke gently on the walk home from school, the scarred hand intertwined with Shouto’s squeezing ever so slightly. Shouto looked at his boyfriend and worry tainted those gorgeous round eyes that he loved so much.
“Yeah, I just like to be comfortable is all,” Shouto offered, turning his gaze back towards the path. Izuku’s mouth formed a thin line, but he did not press the issue.
The rest of the walk was heavy with an uncomfortable tension, that of which he had never experienced around Izuku before. As soon as they reached the dorms, Shouto beelined straight to his room to change out of his uniform and pointedly put on jeans, damn it. They were dark wash jeans however, a necessary compromise.
But that only deepened Shouto’s shame and self loathing. To make matters worse, it seemed like Bakugou was starting to hang around them even more than he already was. Shouto was a self-serving shit bag for it, but he started to put some distance between them.
The simple truth of the matter was that he was betraying Izuku by having this unwanted desire. He didn’t deserve to be around his perfect Izuku, or at least that’s what he tried to tell himself. He could only be so honest in the privacy of his thoughts, but the reality was he just didn’t want either Izuku or Bakugou to figure out what was going on with him.
Shouto didn’t mean to avoid Izuku, but he knew that’s what he was doing all the same. If he wasn’t around him or Bakugou as much, then it would go away. Except it wasn’t going away. Shouto didn’t know what to do because Izuku clearly knew something was going on and was probably suspicious and worried. Izuku hadn’t said anything about the elephant in the room just yet, but Shouto knew for a fact that he would, and soon.
Shouto just didn’t want to lie to Izuku. He didn’t want Izuku to know either. He just absolutely could not lose Izuku under any circumstances. The first person to actually say something to Shouto surprisingly was his brother.
“What’s up Shouto? You’re looking a little down in the dumps today,” Natsuo broached the topic while they cleaned up after dinner at Fuyumi’s house. She had tried to protest, claiming they were her guests, but Shouto insisted, leaving Fuyimi to entertain their father in the tea room.
While things between the three Todoroki siblings and their father were better, they still weren’t great, so Natsuo of course embraced the welcome reprieve from the man and volunteered as well. Shouto was slightly surprised Natsuo even showed his face at all, although it wouldn’t be the first time he showed up to dinner with their father just to appease Fuyumi.
“Nothing’s up,” he replied curtly.
“Alright, so something’s definitely up then. What is it? Trouble in paradise or something?” Natsuo asked, clearly being sincere. Shouto figured, what the hell, this was what big brothers were for he supposed. He sighed deeply, giving his silver haired brother confirmation that he had hit the nail right on the head.
“It’s Bakugou. He keeps hitting on Izuku in front of me,” Shouto pouted, and Natsuo fucking laughed right in his face.
“I didn’t expect you to be the jealous type,” he snickered, very clearly amused by Shouto’s dilemma.
“I’m not,” Shouto stressed.
“Oh,” Natsuo replied casually, the realization of what Shouto was actually saying dawning on him, “so you like both of them then.”
Hearing the words out loud stung in his chest.
“No- I don’t know. I just notice things,” he corrected.
“That’s usually how it starts,” Natsuo hummed, words not sounding at all judgemental.
“But it shouldn’t be this way,” Shouto frowned.
“Shouto,” Natsuo chuckled, “it’s not a crime to have a crush. It’s not like you acted on it right?”
“No, but it’s not that. It’s- when I think about it. I don’t think about myself,” he said, and that got Natsuo’s attention.
“What do you mean?” He asked. Shouto hesitated, looking down at the dishes in his hands while he searched for the words.
“I think about Izuku and him. Together,” Shouto visibly cringed as the words came out. And it pissed him off when Nautsuo laughed again, “This is funny to you?”
“No, no I’m sorry it’s just, I think you’re overthinking this.”
“But, if I'm even thinking about it it’s a betrayal!” Shouto exclaimed, every bit of him feeling and sounding like a little kid throwing a tantrum.
“You didn’t do anything though. I already told you it’s not a crime to think about something. Besides, people have threesomes and shit all the time, it wouldn’t make you a bad person. I can’t even tell you the amount of times I’ve seen couples on tinder looking for a third.”
Shouto frowned deeper, feeling unsatisfied with his brother’s complete disregard of the gravity of the situation.
“I’m not saying go do that– look. We can agree to disagree. If it’s stressing you out this much, then confront this Bakugou kid. It’s completely within your right, I mean, it doesn’t sound like he’s all that subtle,” Natsuo said a little more seriously.
“He’s not.”
“There you go then. Set a boundary, you could use the practice anyway,” Natsuo added facetiously. Shouto elbowed his brother in the ribs for that last comment, but did mull his advice over thoughtfully.
And he did think it over well and good, and he came to a conclusion that Natsuo was right. It was obvious that this wasn’t gonna end unless he drew a line in the sand. If Bakugou knew that his behavior was causing problems for him and Izuku, then he’d stop. Maybe not for Shouto’s sake but definitely for Izuku’s. If Bakugou really did have feelings for Izuku, then he wouldn’t want to fuck up his relationship by coming in between them. Maybe Bakugou was a bit of an asshole, but he wasn’t cruel. He wouldn’t want to hurt Izuku like that.
So that’s what he decided to do then. Just sit Bakugou down, and set a very clear boundary. Piece of cake.
Shouto approached Bakugou by asking him to spar because he thought it would be a little easier to speak freely if he could have that conversation away from prying eyes. He didn’t need any of their classmates listening in. Plus, he was still weird around Izuku and he’d really rather not upset him. He decided that he’d set the boundary first, and then have a heart to heart with Izuku. He’d let Izuku know that it all made Shouto uncomfortable and apologize for avoiding him. Then bing bang boom and things were back to normal.
Shouto didn’t intend to actually spar with Bakugou, but the second they stepped foot into Gym Gamma, Bakugou blasted him with three AP shots in quick succession, forcing him to block with an ice wall, which immediately absorbed the impact of his attacks and exploded to pieces.
“What the hell, Bakugou? Are you trying to kill me?” Shouto scolded.
“Oh come on IcyHot, even you have better reflexes than that. Fight me. This is what you wanted, right?”
After a moment of contemplation, Shouto used his ice to propel himself around Bakugou's back, trying to get a good opening to pin him. But Bakugou just kept using his quirk to fly around, keeping Shouto at his front. They probably looked stupid, like two squirrels chasing each other in a circle.
Eventually, Bakugou got the upper hand and tackled Shouto causing him to land harshly on his back. They wrestled for a bit, neither one of them able to fully incapacitate the other. He was able to grasp Shouto’s wrists and pin them to the ground. He bucked and wriggled wildly, trying to dislodge the blonde before going in to use his quirk again. He didn’t want to actually hurt Bakugou.
“Can’t help but wonder what this is really about,” Bakugou prodded sardonically, and Shouto stopped fighting to squint his eyes at the blonde.
“What do you mean?”
“Really? You just so happened to invite me to spar right before curfew? It’s clear that you have something on your mind so stop pussyfooting around and out with it already, or did you wanna do this all night?”
Obviously Bakugou was smart enough to see through Shouto’s ruse. He should have known. Shouto exhaled slowly, letting his grip loosen where it braced against Bakugou’s shoulders.
“There is something,” he admitted.
“No shit, captain obvious,” Bakugou snorted. Shouto ignored the provocation and took a moment to think about how he wanted to say it.
“You’ve been acting inappropriately,” he settled on. Bakugou’s brows pulled together slightly.
“Inappropriately,” he repeated.
“Yeah. The comments, the way you talk to Izuku is- it’s unnecessary,” Shouto kept his tone calm and even, his guard all the way up. Something briefly flickered across Bakugou’s expression.
“And?” Bakugou pressed.
“And it’s disruptive,” there, he said it. Bakugou exhaled a low and disbelieving laugh.
“Disruptive,” he echoed mockingly. “To what? Your perfect little relationship?”
“Of course,” he said. Bakugou studied him for a second, eyes narrowing slightly.
“Tch,” Bakugou huffed but offered no other comment. He grabbed Shouto’s wrists and pressed them to the floor suddenly, obviously trying to get a rise out of Shouto and deflect, but he didn’t take the bait and instead pressed on.
“If you have feelings for him, then you really should consider how your behavior affects him, and us,” he continued.
Bakugou’s mouth snapped shut and he sharpened his gaze, more or less unreadable. It was in complete contrast with the way he had Shouto’s wrists pinned. Even in such a precarious position, Shouto felt like he had the upper hand, so he kept talking.
“You care about him, right? So you wouldn’t want to make things hard for him.”
“I do care about him,” he admitted with no hesitation or embellishment. More than anything else, that made Shouto’s chest tighten. For a second, neither of them moved.
“Then you understand why I’m asking you to stop,” Shouto’s hands laid flat against the ground. His palms were open in a placating manner that he hoped conveyed his submission and sincerity. He felt like prey under the jaws of a brown bear, purposefully playing dead so as to not set off the beast. Bakugou didn’t answer immediately. Instead, his grip shifted deliberately where he was still holding Shouto down.
“You think that’s what this is about?” he asked, causing Shouto to frown faintly.
“Yeah?” Shouto cocked his head to the side in confusion. Bakugou let out a slow and dramatic breath, something almost like disbelief under it.
“Damn,” he muttered.
“What?” Shouto’s brows knit together, and he really wanted to be in the know, because right then, it felt like Shouto said the wrong thing. Bakugou looked at him properly just then, and it was almost like he was looking right through him.
“You really think this is about me messing around with Deku,” Bakugou licked his lips.
“It is, your behavior–“
“My behavior,” Bakugou cut him off, “isn’t the part you’re stuck on.”
“Yes it is,” Shouto said a little too fast, and Bakugou caught on easily. He tilted his head, unimpressed, leaning in a little closer and lowering his voice.
“Why are you here alone and not confronting me together?”
“Because,” he said after a moment of hesitation, “I didn’t want to upset Izuku.”
“Bullshit,” he sneered sharply. Bakugou shifted, one hand sliding to Shouto’s waist, pinning it more firmly to the floor.
“What are you doing?” Shouto’s voice shook. Bakugou ignored him and continued speaking when Shouto offered no further protest.
“You could’ve told me to knock it off any time, in front of him, in class, wherever. But you didn’t,” he said, and Shouto’s jaw tightened in response.
“That doesn’t change the fact that it needs to stop,” Shouto was on the edge of desperation. He felt like a cornered animal, being pushed and pushed before he eventually cracked under the pressure and attacked. Bakugou watched him for a second.
“No, I don’t think that’s the reason,” the blonde accused. Shouto’s expression hardened, trying desperately to regain control of the conversation.
Then Bakugou leaned in even further, enough that it was unmistakably clear that it was completely intentional.
“You don’t look mad when I say that stuff,” Bakugou whispered. Shouto’s breath caught in his throat.
“That’s not–”
“You look like you like it,” Bakugou cut in again and Shouto could not do anything, hardly even thought a single thought, and froze. Bakugou’s gaze didn’t waver.
“You think I wouldn’t notice? Every time, you just stand there and watch while I come onto your precious little Izuku. Like a fucking cuck,” he mocked.
“Stop deflecting away from the real issue,” Shouto swallowed.
“That is the real issue,” Bakugou’s thumb dug into Shouto’s hip roughly, enough to bruise. Shouto’s pulse picked up, and no matter how much he tried to hold it at bay, his cock twitched hard in his pants.
“No,” he says. “The issue is that you’re–”
“Into him?” Bakugou interrupted. Shouto felt like a deer in headlights, but Bakugou’s expression definitely didn’t change. He looked completely calm and unphased. There was a very tense moment of silence between them, where the only thing that could be heard was Shouto’s panting breaths, and the low rumble of the air conditioning.
“Yeah, I am,” Bakugou said bluntly, taking Shouto completely off guard. This whole time, he had been toiling over this exact question, only for Bakugou to offer up the information up so easily in the end.
“Which is exactly why you should–”
“Stop?” Bakugou finished.
“Stop cutting me off,” Shouto snapped.
“Make me,” the blonde provoked, voice dripping with seduction. And really, it was no different from every single time Bakugou had ever taunted Izuku with sexual innuendo. Except this time, now that he was on the receiving end of it, it felt so much more real and heavy in a way it didn’t before.
This was so dangerous. Shouto needed to escape as soon as he could because he was pressed underneath Bakugou, and he was far too close to doing something so incredibly stupid. So instead he did the first thing that came to his mind. He broke free with one very sudden shove that sent Bakugou flying backwards, followed by a blast of ice that froze him to the ground. Then, he quickly made his retreat out of the building.
Shouto bounded towards the dorms before Bakugou had the chance to break free and follow him. Once he got to his room, slammed the door behind him. Hopefully Sato or Sero weren’t sleeping yet or they probably would have woken up from the slam.
Then, within the privacy of his small bedroom, Shouto immediately stripped down to nothing from the waist down and began to rapidly tug on his cock, with the only goal being to get the fuck off. In what was probably a matter of thirty seconds or less he was violently shooting his load, making a mess of himself and all his blankets.
Shouto caught his breath while endorphins rushed through his body. His hand didn’t even leave his dick before the gut wrenching guilt and fear set in. What had he done? Needless to say, Shouto miscalculated that entire interaction. Who would have thought it could have gone so horrible wrong?
As he stared at the ropes of cum that were literally everywhere, all Shouto thought about how he had made a mess of things, literally and figuratively. Two things were incredibly clear, there was no longer an easy way out of this and he was absolutely fucked. Sure he knew Bakugou’s secret, but now, Bakugou knew his too. It was a real catch 22 and the only thing that could possibly come from all this, was nothing short of pure chaos.
