Gone Too Far

Summary:

When he and Tetsutetsu get into a round of daring each other to do stupid shit, Kirishima's brain draws a blank and he blurts out a game of gay chicken. It ends up going on for far longer than intended and causing him far more stress than he ever expected.

Notes:

I've made this joke way too many times and my friend finally gave me the final motivation to make this into a fic.

Chapter 1: Just a Dare

Chapter Text

Eijiro wasn’t really sure how this had happened. He could recall the events leading up to this moment, sure. But the motivations behind them were beyond him. Either way, he was stuck with the consequences. 

 

And those consequences happened to be Tetsutetsu kissing him in front of his friends in the hall while he was on his way to lunch. In front of both class A and B as well. And the teachers. And any upperclassman who might have spotted them while on the way to lunch. The entire fucking school watched Tetsutetsu grab his tie and pull him into a kiss, where the other proceeded to work his tongue in and practically make out with him. 

 

He knew Tetsu was competitive, but this was a step above. This was going from zero to one hundred. 

 

Maybe he needed to backtrack a minute. Provide some context. 

 

It had all started the night before when they had been daring each other to do gross or crazy things. It was a pretty common activity they did together, as it challenged them to be more tough and manly. Tetsu had dared him to stick his hand into the broken gutter of the dorm building, and after that adventure had gotten him yelled at by Aizawa, they had finally made it back to the couch. 

 

“Okay! My turn! Dare me!” Tetsu demanded. 

 

Eijiro grinned and raised his eyebrows. That had been a hard one to top. His hand still smelled, even after washing it. He had nearly thrown up from the texture of the muck and slime. He wracked his mind for something, anything. “Uhhh, lift the couch while it’s full of people?” 

 

Tetsu growled at him like a wild animal. “No! There’s nobody here and that’s bullshit! You can’t just gimme something easy after you pulled that last dare off!” He bared his teeth. 

 

Fuck, he was right. It wouldn’t be manly of him to deny Tetsu a chance to recover after he had managed to call his dare. What could he even dare that could compare? What could be heinous enough to challenge such a feat, excluding actual crime or getting Tetsu sick or injured? 

 

“Come on!” Tetsu barked, pressuring him. 

 

Eijiro wasn’t particularly quick-witted even at the best of times, and the pressure was beginning to make him crack. He felt a sweat break out on his brow. “Gay chicken!” He finally blurted out. 

 

Tetsu settled down, eyes wide. “Gay what ?” 

 

“Gay chicken!” Eijiro grinned wider. This was perfect, it would totally rival Tetsu’s earlier dare! “We start kissing and we have to keep going until the other taps out from being too grossed out!” 

 

Tetsu’s jaw dropped as he gaped at his friend. The steel cogs in his head were working overtime on this one. “So the dare is just…kissing?”

 

Eijiro nodded. “Yeah, but we’re not gay, so it’ll be gross!” He smirked. “Ya scared? You can always give up for the night and consider me the winner.” 

 

Tetsu clapped his mouth shut and stared at the floor, seeming to weigh his options. Eijiro had really caught him between a rock and a hard place now! Tetsu would totally give in and he’d win this round. He couldn’t help but grin and rest his hands behind his head, relishing his victory. 

 

“Okay, let’s do it.” Tetsu gave a curt nod. 

 

What?! He wasn’t supposed to say yes! Eijiro hadn’t even kissed anyone for real yet, he couldn’t waste his first kiss on some stupid dare he’d thought up on the spot! Fuck, what would he do? “Alright, cool…” His voice came out high and trembling. “So, uh…I guess we just…” 

 

“I should start, since I’m the daree.” 

 

“Right.” Eijiro scooted closer, his heart pounding out of his chest. Was he seriously going to do this? What would he tell his future children?! Not that it was bad to be gay. Being a homophobe was seriously unmanly, but he wasn’t gay. 

 

Tetsu leaned forward and before he could process it, their lips were touching. Warm, chapped lips met his, and his stomach felt like it had managed to fly away and leave him behind. He stiffened in surprise as he felt hands at his waist, but quickly relaxed into the other boy’s touch. He had no idea where to put his hands, so they stayed where they were, gripping his knees. 

 

That was, until Tetsu began moving his lips against his and deepening the kiss. He found his hands moving of their own accord to wrap around Tetsu’s neck and tangle in his hair. He had briefly wondered if Tetsu’s hair was coarse and wiry due to his quirk, but it was surprisingly fluffy and soft. He found himself making an involuntary noise in the back of his throat that sounded high and reedy as Tetsu began moving closer, practically crawling onto Eijiro’s lap. 

 

Finally, Tetsu had to break for air. “Give in yet?” Eijiro mumbled, his speech slurred and his cheeks flushed. 

 

Tetsu grabbed the front of his shirt, glaring at him with his teeth bared. “Absolutely not! I’m only getting started! The only rule I got is no hands near the binder, got it?!” 

 

Eijiro was very used to getting yelled at in the face by Tetsu, in fact he did it right back to him usually. However, this was a rare moment where he was completely stunned silent. He could only dumbly nod. 

 

Tetsu gave another curt nod and went right back to kissing Eijiro, this time with more confidence. His lips began once again moving against Eijiro’s own, but this time after a few minutes of deep kisses he began to feel the other boy softly licking at his lips. He was going to open his mouth to ask what that was about, but instead got the surprise of Tetsu’s tongue in his mouth and made a garbled noise of surprise that ended in a soft moan. Tetsu’s tongue was hot and slick against his own, and he gently tugged Tetsu’s hair as he gasped into the other’s mouth. 

 

This was not good. This was not how gay chicken was supposed to go. He was supposed to be disgusted and uncomfortable. Instead…he could feel heat stirring in his belly as Tetsu’s hands slipped under his shirt and began wandering over his chest and stomach. They were so, so close right now. Tetsu was literally sitting on his lap, all he needed to do was shift a bit and push his hips down to-

 

Fuck. 

 

He bucked his hips involuntarily as Tetsu began grinding against him. He was absolutely hard now, no question about it. Why was he getting so into this? Why was this turning him on, he wasn’t gay! 

 

“Ow! Fuck!” Tetsu ripped away from him, holding his mouth. “You bit my fucking tongue!” 

 

Eijiro winced, he had gotten so absorbed in his anxiety about his sexuality that he hadn’t been careful about his teeth. “Sorry bro.” 

 

Tetsu pouted. “Well, if you think that’ll make me give in, you’re wrong!” 

 

Eijiro smiled, getting concerned. “Hold on, I don’t wanna hurt you, we can call it for tonight.” He could regroup and take a cold shower to kill his hard on, then shove this into a box and try to forget it forever. 

 

Tetsu glared at him, then his face went slack in surprise. His hips pushed down, making Eijiro groan. “W-wait, Tetsu-” 

 

“I knew it!” Tetsu grinned. “I won!” 

 

Eijiro scowled. “No you didn’t, I didn’t tap out.” 

 

Tetsu grinned wide at him, and Eijiro couldn’t hold back the squeak that came out of him as he felt the other boy’s hands slip under his shirt and brush over his nipples. “Then the game’s still going, isn’t it?” 

 

Eijiro whined and let his head fall back. “B-but we just agreed on kissing…” 

 

Tetsu shook his head, fully humping his crotch now. “No, you said that we would start kissing. You didn’t say anything about how far we could go. But if you’re too chicken you can back out and let me win.” He grinned and leaned forward to begin leaving a soft trail of kisses down Eijiro’s neck. 

 

“Ah, absolutely not.” Eijiro whimpered, eyes screwing shut as he felt sharp teeth graze his neck. 

 

There was the quiet mechanical whirr of an automatic nerf gun, and before Eijiro could acknowledge what was happening he and Tetsu began getting pelted by nerf bullets. “Curfew.” Aizawa growled as he walked through the dorm hall lounge. 

 

Tetsu was off of Eijiro with record speed, stumbling away from the couch. “S-sorry Mr. Aizawa!” He gave a salute. 

 

Aizawa glared at the two of them with narrowed eyes, then took out a walkie-talkie. “Tetsutetsu’s in the Class 1-A dorm building. I’m sending him back to 1-B now.” 

 

The walkie-talkie answered with Vlad’s voice through a tinny speaker. “Copy that, thanks Erasurehead.” 

 

Once Tetsu had left, Eijro began rubbing his clammy hands on his pants. Holy shit, how much time had passed? It had only been seven p.m. when he and Tetsu began kissing, had they really been making out for two hours? 

 

Eijiro’s face currently matched his hair color. “Mr. Aizawa, we were just-” 

 

“Don’t care.” Aizawa cut him off. “Go to bed.” 

 

“It was a dare!” He insisted, eyes wide. “Just a dare.” 

 

Aizawa held the nerf gun up, his quirk making his eyes glow red. “I do not. Care. Bed. Now.” 

 

Eijiro stood up, feeling humiliated. “Just don’t tell anyone, please.” He mumbled. 

 

“I don’t think you have the right to make requests, considering you’re out a half hour past curfew.” 

 

“What?” Eijiro’s eyes widened. He pulled out his phone, and sure enough it was nine-thirty. “Holy shit, I didn’t know we were in here that long.” 

 

Aizawa seemed to calm down a bit at that. “This is your first offense, so you won’t lose any privileges or have anything on your record. If it happens again, however…” 

 

Eijiro nodded. “Understood.” He felt terror as he realized on the way back to his dorm that when he was speaking to Aizawa he still very much had an erection, as he looked down while walking to see a tent in his pants. 

 

And now back to the equally mortifying present, the day after, where Tetsu was seemingly attempting to figure out how much of his tongue he could fit into Eijiro’s mouth. And as much as he hated to admit it, it felt good . His lips were soft and hot and he nearly forgot that half of the fucking school was watching them. 

 

“What’s this?! It looks like there’s a relationship forming between a class A student and a class B student, but the class B student is the one who’s topping!! Isn’t that wild that the weak class A student is submitting to someone from class B?! It looks like class A isn’t so tough after all!!!” Monoma crowed as he gestured wildly at the two boys kissing. Normally, Kendo would be hitting him to shut him up right about now, but she too was staring in abject shock along with the other bystanders. “And on top of that, Tetsutetsu is trans!! You’d think with all the advantages of being in class A and being cis Kirishima would be the one that was able to take charge, but oh no!!” 

 

Eijiro finally managed to break the kiss, breathless and flushed. “What…what the fuck?” 

 

Tetsu grinned at him. “The gay chicken isn’t over! Neither of us tapped out last night, so it’s still going!!” 

 

He was right. Aizawa had stopped them, so technically the dare was still ongoing. “Shit…” Eijiro began taking stock of their surroundings. Tetsu had really pressed him now. It was hard to out-gay someone who had french-kissed him in front of most of the school. “This is gonna be hard to top…” He resumed his walk towards the cafeteria. 

 

Tetsu followed him, fist hitting into his palm and grinning smugly. “You could always give in and let me win.” 

 

Eijiro chuckled nervously. “No way, I can’t just let you have such a big win like that!” His tone was an attempt at their usual competitive banter, but it fell pitifully short as he was still mentally recovering from the kiss. 

 

He felt like he was walking into an interrogation as he caught up with his friends from his own class. “Sooo…you and Tetsu, huh?” Mina grinned, practically vibrating in her seat. 

 

Eijiro felt his face burn. “No, it’s not like that!” 

 

“What the fuck else could it be?” Bakugou glared at him. “Guy had his tongue down your throat.” 

 

Eijiro gave a nervous laugh, wanting desperately to go back in time and stop himself from ever suggesting the game. “Me and Tetsu started playing gay chicken last night.” 

 

“That sounds fake.” Kaminari smirked. 

 

Sero leaned forward, resting his chin on his folded hands. “I’ve heard of it.” He narrowed his eyes. 

 

“What, you played?” Kaminari raised an eyebrow. 

 

“No, but my friend in middle school did.” 

 

“What happened?” Kaminari asked, leaning forward. 

 

“He totally ended up being gay. He’s not with the guy he played with, but I saw on his Instagram he had a boyfriend.” 

 

“I’m not gay!” Eijiro scowled. “It was just us doing dares last night and it slipped out! I couldn’t think of anything else to top Tetsu’s dare.” 

 

“So you were the initiator of the gay chicken?” Mina narrowed her eyes, mirroring Sero’s stance. 

 

“It just slipped out! I couldn’t think of anything else!” Eijiro yelled, his face burning. “Seriously, you guys! I’m not gay!” He groaned as his head fell into his hands. “And now I totally lost, there’s no way I can top the stunt Tetsu just pulled.” 

 

Kaminari turned towards Mina and Bakugou. “Well, you guys are the resident gays of the friend group. Any suggestions?” 

 

“Go fuck yourself.” Bakugou replied flatly. “And I know you’re bi.” 

 

“Yeah, so I’m only part gay. I think we need the perspective of a full-blooded gay to really help our buddy out.” Kaminari leaned back in his chair. “Obviously at this point anything PDA related is off the table, since the only way you could top Tetsutetsu is by doing stuff that would probably get you expelled.” 

 

“Ooo, do something romantic!” Mina grinned. “Some big romantic gesture that the whole school will see!” 

 

Eijiro scowled. “No way, that would actually be gay, I can’t actually be gay!” 

 

Bakugou’s eyes darted between their table and the one where Shouto was sitting. Usually, the two sat at different tables despite being together, due to Bakugou being hostile at the best of times towards Midoriya. Right now, however, he seemed to be reconsidering. 

 

“You know what you could do?” A voice asked from the end of the table. 

 

Oh god. 

 

Mineta smirked. “Obviously a public act would be off the table unless you’re willing to get into trouble, but private stuff would still be an option.” 

 

Eijiro’s lip curled up into a sneer. “I don’t wanna know.” 

 

“You realize you picked the perfect opponent for gay chicken, right?” Mineta brought his fingertips together in a calculating pose. “If you play your cards right, what you do wouldn’t technically be gay.” 

 

“What the fuck are you talking about?” Eijiro scowled. God, the guy was so creepy. He only sat here because he and Kaminari shared a brain cell when it came to girls. 

 

“Tetsutetsu is a transgender man, right? So if you eat him out, you’re eating out a pussy. Erego, not gay.” Mineta smirked deviously. “It’s a foolproof plan, as long as you focus on his genitalia you aren’t gay.” 

 

Mina frowned. “Yeah, but Tetsutetsu is a guy, so it’s a guy’s pussy. That would be gay.” 

 

“Impossible, vagina cannot be gay.” Mineta shook his head. 

 

Eijiro was really getting annoyed with this. “So you’re telling me I won’t be gay if I just don’t accept Tetsu as a man?” He grit his teeth. “Fuck you, you little purple gnome! Tetsu is more of a man than you’ll ever be!” 

 

“Then the game is lost.” Mineta sipped his drink. 

 

“I can’t do this shit anymore.” Bakugou said, standing up. “I’d rather deal with fucking Deku than hear another second of this stupid-ass conversation.” 

 

Eijiro glared at Mineta as his friend walked away. If it hadn’t been for Kirishima, Bakugou probably would have been sitting alone. He probably wouldn’t have ended up with Shouto, and he probably wouldn’t have ever told anyone about his shitty homelife or the way his mother treated him. The guy tended towards isolation. “Are you happy with yourself?” 

 

“You were the one trying to figure out how to top Tetsutetsu’s play.” Mineta shrugged. “I’m just telling you.” 

 

Eijiro sighed and sat back in his chair, keeping quiet as the normal banter began to start up between his friend group. He couldn’t help but let his eyes wander across the cafeteria until they fell on Tetsu’s table. He looked to be having some kind of animated conversation with Kendo. The guy always spoke highly of her, Eijiro wondered if Tetsu had a crush. He couldn’t help but frown a bit at that. Why? Why would he be into her? Her quirk was weird, and who the fuck wore side ponytails unironically? She was…pretty and smart, but…

 

He was pulled out of his angry train of thought as he realized Tetsu had stood up from his cafeteria chair and said something to the others. Monoma seemed to think what he said was hilarious, as he cackled. Tetsu then turned from the table and began walking towards Eijiro’s table. 

 

Eijiro’s mouth fell open and he turned back to the others. Why was he coming over here?!? Hadn’t he done enough?!? 

 

“Ooo, your boyfriend’s coming over!” Mina giggled and poked his arm. 

 

“Shut up!” Kirishima hissed through his teeth. 

 

Sero and Kaminari began making kissing sounds in response, and Kirishima gave them the finger. “Fuck all of you! Shut the fuck up!” 

 

“Hey.” He heard Tetsu mumble from behind him.

 

He whirled around, grinning. “Heyyy! What’s up?” 

 

He wanted to smack everyone in the chorus of muffled giggles he heard behind him. 

 

Tetsu shifted from foot to foot, staring at the ground. All the confidence he’d had kissing him in the hall was gone. He rubbed the back of his neck. “So…you wanna um…do you wanna grab food after classes? Like, somewhere nearby campus? I could ask Mr. Vlad for permission…”  

 

What the fuck? Hadn’t he gotten enough of an advantage over Eijiro with that kiss? Why was he pushing even further by asking him out? Well, Eijiro wasn’t going to back down, that was for sure. “Yeah, sounds great! I heard there’s a new ramen place nearby we could check out, just lemme ask Mr. Aizawa if it’s okay.” 

 

Tetsu smiled a bit. “Cool. Great. I’ll uh…I guess I’ll seeya then.” Why was he acting so shy all of a sudden? What the fuck was going on ? 

 

“C-can’t wait!” Eijiro grinned and gave a thumbs up. 

 

Tetsu’s cheeks dusted pink as he gave a small wave, then turned and left to go back to his own friend group’s table. 

 

Eijiro turned back to his friends. “I’m going to fucking murder all of you.” He deadpanned, shooting everyone a glare. 

 

Sero grinned. “Dude, he asked you out.” 

 

“Yeah, so?” Eijiro’s scowl deepened. 

 

“On a date.” Sero raised his eyebrows. “Like, a real date.” 

 

Eijiro scoffed. “Obviously it’s for the dare!” 

 

“Are you sure?” Kaminari asked, raising an eyebrow. “He seemed pretty genuine.” 

 

Did he? Eijiro felt so confused since last night. Before, he had been a confident ally to his trans friend and his queer friends. Just a happy-go-lucky kid, supporting friends and not being involved. Now…no. He wasn’t gay. This was all part of the challenge. Tetsu was bringing his usual competitive spirit, and Eijiro wasn’t going to back down. “No, it was definitely just part of the game.” 

 

“No wonder you turned down my advice, it appears the game is already lost.” Mineta spoke. 

 

“Who’s the loser, you think?” Kaminari leaned towards him, mumbling. 

 

Mineta hummed. “Who knows? The results are they’re gay. I’m gonna spend the rest of lunch looking at skin mags in the bathroom.” He hopped down from his chair and strolled away from them as if he hadn’t just announced his intentions to masturbate. 

 

Eijiro rolled his eyes and got up to return his tray and ask Mr. Aizawa for permission. It was a date, but it wasn’t a date . This was just a game. 

 

He was telling himself that more and more frequently. 

 

He approached the teachers’ table, hardening his resolve. “Mr. Aizawa?” 

 

Aizawa looked over at him from a conversation with Midnight and Present Mic. “Yeah?” 

 

“Can…can me and Tetsutetsu have permission to leave campus after classes? We wanna um…we wanna check out a ramen shop nearby.” 

 

“Like a date?” Vlad King interjected, grinning. 

 

“N-no, it’s not like that!” Eijiro pursed his lips. “It’s a dare. We’re playing gay chicken.” 

 

“Gay what?” Aizawa narrowed his eyes, then swatted blindly as Present Mic burst into giggles next to him. 

 

“Gay chicken.” Eijiro swallowed, his mouth now bone dry. “Like, you start kissing a friend and keep going until one of you taps out. We started playing last night when you interrupted, so…it’s still going.” 

 

Aizawa’s jaw dropped and his right eye twitched. It was extremely clear that he wanted to use harsh words on his student but was exercising self control. After a few moments, he shook his head and regained his composure. “Let me make this clear: I do not give you permission to leave campus after your incident last night.” 

 

“Aw, come on Eraserhead, you can’t get in the way of their little romance!” Vlad pouted at him. 

 

Aizawa held up a hand to silence him. “Now that I’ve told you my decision, I’d like to clarify: you and Tetsutetsu aren’t dating?” 

 

“No.” 

 

“Are you sure?” 

 

Eijiro paused. “Well…no. It’s not gay if it’s a dare.” 

 

“Oh, yeah.” Present Mic leaned forward, grinning wide. “Friends totally make out with each other and go on dates in a totally platonic way. That’s not gay at all!” His breath was punched out of him as he was elbowed under the table by Aizawa. 

 

“I would strongly suggest thinking more critically about your relationship. And next time, it would be wise to be a bit more clandestine about this sort of thing. Things have improved a lot in the past decade, but gay pros still get denied cases regularly.” Aizawa seemed to consider that the final word on the situation, as he stood up with his tray and walked away from the table. 

 

Eijiro sighed and trudged back to Tetsu’s table to break the bad news to him.
