Kiribaku/BNHA/Mutual Masturbation

Kirishima x Bakugou

After the series of attacks delivered by the League of Villians, it took three days to build The Heights Alliance. Or as most students call it, the dorms. Now even Bakugou was impressed with it, it was a huge building which housed each and every UA student. He was even fortunate enough to be placed next to one of the more bearable 1A students, Kirishima.

When he said bearable, he meant that the red readed boy was a friend. Everyone knew that Kirishima was one of the few kids Bakugou didn't want to kill on sight. And Kirishima was pretty proud to hold that title. And although no one knew, Kirishima prayed that one day he'd hold a more significant title to Bakugou. Though he'd never admit it.

The downside of this large building is that U.A didn't really have enough funds to make it as luxurious as their classrooms or training areas. More specifically, the walls were paper thin. Sound echoed and travelled through the drywall to anyone within 10 feet. And the distance between Kirishima and Bakugou was less than that.

Kirishima could hear every small explosion, every microwave timer, and every frustrated growl that Bakugou made. And Bakugou could hear every time Kirishima would stub his toe, every time he did target practice, and this time, when he masturbated.

Bakugou tried and tried to block the moans, he covered his ears, tried to go to sleep, he even played music. But the sound was sickening, it was personal, it wasn't how he wanted to imagine Kirishima. After months, he became used to it, but undoubtedly it would still make him flustered and red in the face. And it didn't help that his imagination would run wild, he could see Kirishima leaning against the wall, slender fingers wrapped around his length, small moans escaping his lips.

He supposed thats how he came to this. Door locked, sitting in the ground against the wall listening to his best friend make sweet music from his lips, cries of pleasure. He was sitting on his hands, sternly reminding himself who he was eavesdropping on. Then he heard it, like a shot in the night:

"Ahh-ah Katsuki~"

Bakugou froze, he realized that his right hand was palming himself through his sweatpants, he stopped. A bead of sweat slid down his temple. He must have imagined it, he assured himself. Kirishima would never- would he? No. Not by his first name. But he heard it again:

"Fuck- Katsuki~"

It was loud and clear this time. Bakugou seemed in shock but his hand was moving, snaking under his waistbands and sliding down his length. He didnt want to stop now. He winced and shivered, closing his eyes, he rested his head against the wall, his ear could hear clearer now.

Kirishima was standing, one arm above his head, supporting his weight against the drywall. He free hand was moving up and down his painfully hard cock. He was suprised when Bakugous name fell through his mouth. But it didn't stop him, if anything it fueled him to go harder. His legs gave out as he ran his thumb against the head, he sank to his knees and he could have sworn he heard a noise. He almost paused but he was so close, too close to stop. He yanked his pants down more, eager to relieve himself. He took his dick in his hand again and pumped it.

His eyes were shut tightly, his sharp teeth piercing his bottom lip. He could see him. His strong arms around his waist, the caramel smell of his skin, his hands... Kirishima gasped.

"Katsuki!" He whimpered, releasing on his hand and thigh.

He realized he was shaking, he rested his head against the wall and could hear an echo to his panting.

"Mmph shit..." Bakugou growled, he was on his knees now, his hand going rapidly at his erection.

He couldn't stop thinking about him, his- dare he say it- best friend. He started thrusting his hips against his hands, letting his cock slide through his loosely closed fist. He tilted his head back, going faster.

"Ahhh- fuck! No- Ah~" he growled, trying to stop himself. He wouldn't do it he wouldn't moan shitty hairs name.

But the thought of his body below him, falling apart at his touch, those scarlet eyes looking back at him, it drove him mad. He thrusted aggressively once more, his hands tightening around himself.

"Ahhh fuck- Kirishima~"

His gut tensed and he came violently, his legs shaking, he plopped down off of his knees. He peered down at the mess below him, riding out his high.

Its like Kirishima was hit with realization about what he heard and what he did all at once. He shot to his feet, pulling up his pants fanatically, he grabbed a towel and cleaned himself up.

Had Bakugou seriously... moaned? He was sure it was a mistake until he heard his own name. Then he really hoped it wasn't a mistake.

He readjusted his now uncomfortable pants and grabbed his bucket full of shower soaps with a large clean towel. He figured he'd take a shower to wash away all this confusion and grime. He took a deep breath and opened his door.

"BaKugOU." Kirishima looked at the grumpy boy wide eyed. He cleared his throat,

"I mean hey man whats up?" He felt his face turn red. He had a towel too and a handful of soaps. Please don't tell me he was showering too.

Bakugou suddenly stepped forward and shoved Kirishima back. He slammed the door.

"Shut up and fucking kiss me shitty hair."
