Notes:

aslkdlksmadksld
This is my very first fic. In my entire life. I usually have a policy about writing fanfics (Because I feel like I would be garbage at characterization and maintaining OC personalities) But I think this went pretty well.
Did it go well? O man, it was garbage wasn't it?

*If this isn't a terrible flop, I might expand this. *winks, but like, badly* And upload my other fluff.
Maybe.

Work Text:

Midoriya paced in his room muttering his thoughts under his breath. It was late, late enough that all good little heroes were already in bed. So, the chances of him being discovered awake were very unlikely. Probably. The thought of getting caught, of having to explain himself, was almost enough to keep him in his room for the night. Almost.

His hands shook, remembering the invitation he received via text.

Midoriya cracked open his bedroom door, scanning the halls for signs of life. Nothing. He was pretty sure Aoyama had went to bed hours ago-he took his ‘beauty sleep’ very seriously. Tokoyami was the only other person on this floor, and while Midoriya was sure he was in his room, Midoriya couldn’t help but recall that Tokoyami sometimes had a tendency to walk around after hours. (Something about ‘revelry in the dark of the night.’)

Having trouble sleeping. Come distract me?

And devising a quick plan- Really all he needed to do was get to the end of the hallway, open the stairwell door, jog up the stairs, open the stairwell exit door, run down to the other end of the hallway, open the connecting stairwell door, and rinse and repeat three times- Midoriya snuck out into the hallway, easing his door shut with a inaudible click.

Midoriya cleared the first floor and the first set of stairs with quiet efficiency. He had to step softer than usual on the second floor, imagining a feather falling to the floor instead of the fall of his feet, in order to not wake the sleeping beast that was the Class Rep.

Opening the stairwell door and closing it behind him was a task and a half, but he managed, leaning against the cool metal frame and breathing fast and deep. Okay, breathing wasn’t the right word. He was practically hyperventilating. His heart was rapidly firing in his chest, making his hands sweat. He could do this, though. He would.

Come distract me?

He pushed away, climbing the next set of stairs. He was nearly half way to his goal. The big vinyl ‘4’ on the stairwell door hovered just out of reach. Only one floor left after this one.

Midoriya stepped out into the dark corridor, stopping once again to take the time to close the door softly behind him. He had intentions of tiptoeing passed Shoji’s room (Who knew how many ears the guy had out listening to the hallway traffic this time of night) as soon as he shut the door. His head was already feeling clearer, his body elated that he had nearly gotten away with it. He could already feel the tsunami of hot and cold pressing over him, tantalizing him…

Of course, all that positive thinking flew out the window when he heard the soft opening of a door, saw a crack of light splay across his feet. It was almost enough to make Izuku curse. Not Kacchan, not Kacchan… He didn’t think he could muster the brain power to lie to his childhood friend’s face. And telling the truth was way out of question.

Steeling himself, he turned around and came face to face with a shirtless Kirishima. They both froze, neither of them saying a word. Midoriya ran through excuses in his head, Hey, Kiri, I’m just up using the bathroom… No. Oh, uh, I couldn’t sleep and needed to take a walk… Each excuse he came up with, had him imagining Kirishima’s responses. The bathroom? Why didn’t you go to the one on your floor? Or worse, A walk? And you couldn’t even put on a shirt? Or… pants? And why is your hair.. tamer than usual?

Midoriya blushed a deep red, a startling contrast to his bright green locks. He had been caught, sneaking upstairs. Did he keep going? Pretend he didn’t see Kiri? Maybe, the other boy would be too sleepy to remember this confrontation in the morning.

“Kirishima. W-what, uh,” Midoriya cleared his throat. “What are you doing up at this hour?”

For a brief pause, Kirishima just stared, resembling a deer in the headlights of a car intent on slamming into him with no way to change the outcome of being steamrolled. His hand lifted from the door knob to his dorm room to massage the back of his neck. His lips pulled tight over his sharp teeth in an awkward smile. His eyes darted to the side and back so quickly Midoriya didn’t notice.

“Uh, what…?” He laughed a little, tension tight in his shoulders. “What are you doing Midoriya? Your room isn’t on this floor.”

If it was possible, Midoriya’s face flushed hotter. Redder. “Me?” He squeaked out. “Oh! I, uh-“

His impromptu-and undoubtedly lame- excuse was cut off as another door opened. Midoriya’s muscles locked down tight. Great, another witness. He wanted to die.

Kacchan leaned out, oblivious to Midoryia, and quipped a snarky, “Oi, Shitty hair. You forgot your shirt.” His lips curling in a devious smile he added, “You might want to wash it-“ He immediately trailed off once he saw the situation, his face shifting from-was that a look of happiness on Kacchan’s face?!- to animosity. Murder filled his red eyes.

Midoriya’s eyes nervously flickered from Kirishima’s face, a very shirtless Kirishima (whose blush now rivaled Midoriya’s own) to his naked chest. His gaze dragging down to take in the light shadows of bruises starting to form on his neck and pecs that he had missed the first time he’d looked at the red head. Midoriya’s gaze shot to Kacchan, also shirtless, pants unbuttoned and slung over hips that displayed more of the same bruising, bite marks that identically resembled Kiri’s shark-like teeth…

He very deliberately avoided looking at the crumbled tee-shirt in Kacchan’s hand, wet with—

Midoriya looked anywhere but at the pair, nigh choking on his own tongue. This was bad, bad, bad. Bakugou’s hands were sparking with his anger and he was starting to stalk forward. His voice was low, threatening. A warning. “Deku.”

Kirishima was fast, throwing his arm across his (boyfriend’s??) chest to stop him from, most likely, committing murder, grounding him like he did the day they all hung out at the pool. He didn’t even harden his skin, Midoriya noticed, no doubt in Kirishima’s mind that Kacchan wouldn’t hurt him, intentional or otherwise.

Always a hero, and partly to fill the awkward silence, Midoriya started talking. Intent on saving the situation. Even if it meant costing something of himself. He pressed his index fingers together, taking a step backwards out of habit. Face flaming, in a voice barely above a mutter he said, “I was uh, going up to T-Todoroki’s room.”

The hallway filled with silence as everyone contemplated the specifics on what Midoriya had just confessed. And yeah, Midoriya definitely should not have outed Todoroki like that. But he felt it was necessary to offer a secret for the one he accidently exposed.

Mentally fighting his habit of nervous talking, he stopped himself from adding, You know… Apparently for the exact same reason Kirishima went to your room, Kacchan

He decided it was best he not remind the couple of the situation he walked in on.

Kiri’s smile lit up again and he dropped the arm holding Kacchan back. “That’s real manly of you to admit, bro. I’m happy for you!” Turning he said, “See Katsuki? Everything is—”

Bakugou’s teeth clenched. “Everything is not fine.” Quicker than Kirishima could react, the blonde flew forward and wrapped his fingers around Midoriya’s throat. He wasn’t choking, it didn’t hurt. It was just aggressive pressure. Another warning.

Using his grip on his throat, he slammed his back into the wall, robbing him of breath.

“K-Kacchan-“

“Katsuki!”

Bakugou talked over both of the boys’ protests. “Listen to me Deku. If you breathe one word, one single word, of this? I’ll explode the freckles off your fucking face. And I won’t stop there, you hear me?”

Midoriya nodded, trying very hard to meet Kacchan’s eyes and not linger over the flush of Kirishima’s cheeks or his kiss swollen lips as he pulled at strong shoulders. He tried to focus on regaining normalcy in his breathing and not the erratic faint red lines on Kacchan’s pale skin, gifts from Kirishima’s nails.

Bakugou nodded, dropped his hands and stepped off, leaning down to snatch the discarded shirt off the floor. He grabbed Kirishima’s hand with his free one, intertwining their fingers. Tugging him toward his bedroom door he murmured, “Eijiro, room. Now. He won’t say shit.”

With what Midoriya thought was a roll of his eyes and a huge grin Kirishima said, “I know he won’t Katsuki.” There was a tightening of fingers, a soft, “Honestly, would it be so bad?”

Midoriya didn’t catch Kacchan’s rushed response.

Kirishima tossed one last smile back at Midoriya, before Bakugou let out an angry tch, and shut the door between them.

Unable to move just yet, unable to wrap his mind around what just happened…

Midoriya stood in the now empty hallway. Kacchan and Kirishima? He smacked his palm into his forehead. He was an idiot. Of course, there was something there. The two always arrived together, left together, studied together. Kirishima seemed like the only person in the world Kacchan actually liked…

Wow. He thought as he continued for the fifth floor. The two had seemed relaxed, comfortable, well-loved, he thought with a blush. How many nights had Kirishima been sneaking into Kacchan’s room? And what about Midoriya? This was his first venture out in the middle of the night. How many would it take for Shoto to look at him the way Kacchan had briefly looked at Kiri before he’d seen a witness standing there?

Come distract me?

He couldn’t wait to find out.
