The moment Kirishima felt Bakugou nod against his neck, that was it.

A heated growl that Kirishima barely recognised as his own voice ripped from his lips and he flipped their positions, pinning Bakugou against the wall. His hand moved up to grip Bakugou's chin, tilting his head back in order to gain better access when he instigated another kiss, his tongue immediately pushing into the other boys mouth.

Bakugou let out a gasp, his back arching against the wall, as he opened his mouth further, allowing Kirishima to explore his mouth with his tongue, running it along the roof of his mouth and massaging it against Bakugou's own, before dragging Bakugou's lower lip into his mouth and biting down.

Bakugou mewled, his voice ringing through the room, and Kirishima found himself feeling grateful it was so late in the night, otherwise the rest of the class would definitely hear them.

Bakugou's hands found Kirishima's waist then, and didn't hesitate to tighten his fingers into the fabric and yank on it, trying to tug it over Kirishima's head. A grin spread across Kirishima's lips, and he leant back, reaching a hand down to pull his shirt off, before latching back onto Bakugou, his lips venturing down the other boys jaw, trailing open mouth kisses as he went.

Bakugou let out an impatient huff, and he squirmed against Kirishima, trying to take his own clothes off, but failing due to the pressure of Kirishima's body against his own.

Kirishima chuckled, his voice coming out deeper than usual, and he moved his hands up, tearing Bakugou's shirt straight down the middle. He expected some sort of complaint from Bakugou at that, but the other boy simply growled, the sound vibrating low in his chest, before arching his back again, fingers curling into Kirishima's hair and pulling on the fiery strands.

Kirishima felt a moan force it's way out of his own mouth then, and he latched back onto Bakugou's neck, biting and sucking until dark bruises began blooming under his ministrations. Bakugou was shaking now, his entire body quivering with every touch, and Kirishima felt his heart swelling enormously in his chest that he could make Bakugou lose control like this.

Bakugou's hands were exploring all over Kirishima's bare chest now, running his fingertips along each crevasse of the rippling muscle on his stomach, before dipping his fingers down along his hipbones.
Kirishima shivered at the touch, and quickly lowered his own hands, gripping the band of Bakugou's track pants and shoving them down roughly as Bakugou did the same with his.

Once both of their pants were off, Kirishima shifted his hands to the back of Bakugou's thighs and hitched him up, using the wall behind him as a brace whilst he wrapped Bakugou's legs around his waist.

Bakugou mewled again, his hips bucking forward, rubbing his crotch insistently against Kirishima's lower stomach, before Kirishima gripped onto him tighter and carried him the couple steps over to the bed.

He flung them both down roughly, never moving away from Bakugou, as he hovered above them other boy, returning his lips to Bakugou's own.

They lapped and moaned into each other's mouths as their hips jutted desperately against the others, their cocks caught between their stomachs. Bakugou threw his head back, letting out a particularly loud moan, and Kirishima had to stop for a moment just to marvel at how inhumanly breathtaking the noise was.

Bakugou wasn't having that of course, and with another low growl, gripped onto Kirishima's shoulders tightly and flipped them over, pulling his knees up slightly so he was straddling the other boys lap.
His lips dropped down to Kirishima's ear, grazing his teeth along the earlobe for a moment before speaking, his voice breathless and husky.

"Fuckin please tell me you have lube."

Kirishima bit back a laugh at how frustrated Bakugou sounded, and reached his free hand down the side of the bed, gripping the small bottle that was tucked beside his bedside table. He immediately pressed the bottle into Bakugou's hand.

Kirishima was beginning to feel really nervous. He had never fingered himself before, and if Bakugou wanted to top it was going to make for a very awkward conversation, but before he could think much more into it, Bakugou had squirted lube onto his own fingers and brought them down, pushing a single digit into himself with ease.

Kirishima whined at that, his eyes widening and his body squirming uncontrollably as he watched Bakugou finger himself open, his head thrown back, neck littered in all of Kirishima's love bites. A small whimper left Bakugou's lips as he pushed a second finger in.

It was clear that he had done this before, and Kirishima was helpless to do anything but wait, his cock straining against his stomach, thumping painfully as he drank in the sight of the boy on top of him.

Before long, Bakugou was pumping three fingers in and out, his mouth hanging open and his hips twitching, before he pulled them out and looked down at Kirishima, a self-satisfied smirk spreading on his lips. He looked so smug, and Kirishima felt weak with lust as they locked eyes.

Bakugou wriggled forward slightly, before lifting his hips, wrapping one lube covered hand around Kirishima's length and pumping lazily for a moment, causing Kirishima to let out a breathy moan, his hips jerking.

Bakugou met Kirishima's eyes then, half-lidded and filled with fire, before lowering himself down on Kirishima's length, never breaking eye contact.

Kirishima grit his teeth, fighting the urge to begin bucking his hips up into the warm, tight heat, his fingers curling into the sheets tightly as he battled his own self-restraint.

After a few long seconds, Kirishima was fully sheathed inside Bakugou, and he had never seen Bakugou look so smug. Bakugou rolled his hips in small, tight circles, and Kirishima felt moans ripping from his lips, his entire body shaking uncontrollably.

Bakugou leant down, his lips going straight to Kirishima's neck, and latched on, sucking and biting as he continued his ministrations. Kirishima could basically feel the smug air surrounding Bakugou, and with a snap decision, he gripped Bakugou's hips, lifting them up and began fucking himself up into that tight heat.

Bakugou whimpered, a sound Kirishima didn't even know the other boy was capable of, his lips stilling on Kirishima's neck.

After a couple thrusts, Kirishima's restraint snapped completely and he flipped them back over, gripping Bakugou's thighs and shoving them back so his legs hooked over Kirishima's shoulders, before he began ruthlessly shoving himself in over and over. He angled his hips slightly, changing the position minutely with each thrust, until he found the small bundle of nerves that causing Bakugou to let out a shout, the sound quickly being cut off by a series of uncontrollable moans.

Kirishima pounded forward, assaulting Bakugou's prostate with merciless precision, his own gasps and moans joining the mix, panting hard as he kept his rhythm going.

"FU- NGHHH- FUCK EIJIROU!" Bakugou cried and Kirishima felt the heat immediately flood his stomach at his words, pooling low as his determination grew, his hips only jerking forward faster and harder.

He could smell smoke, and a part of his mind snapped to attention as he quickly hardened his back, feeling rapid explosions detonating from the palm of Bakugou's hands as he reached his peak, his mouth falling open and moisture gathering in the corner of his eyes as he whimpered and whined, his neglected cock dripping between their stomachs.

Kirishima knew he wasn't going to last much longer, but he didn't have anything to fear as Bakugou let out a scream, his hips jerking around uncontrollably as his entire body vibrated. Kirishima could feel the cum pulsing from him between them, and kept his thrusts steady until Bakugou went still, his mouth still hanging open, before a couple rough thrusts sent Kirishima over the edge, his cum filling Bakugou as he moaned, his head moving down to catch Bakugou's lips with his own as he rode out his own orgasm.

After a few moments, he pulled out, feeling a grin spread on his lips as his cum slid from Bakugou after him, pooling onto the sheets. He shifted and laid down beside Bakugou, pulling the other boy into his chest as he joined their lips again, their tongues dancing in lazy unison as they came down from their high.

Kirishima could feel three words bubbling up his throat, flooding his throat and trying to force their way through his teeth.

It felt like swallowing glass when he gulped them back down.

~~~

Kaminari felt uncontrollable sobs ripping from his throat, his tears a waterfall as they drenched his cheeks. He had a hand clasped over his mouth, the other arm wrapped around his knees where he had them pulled up into his chest.

Kirishima and Bakugou.

He hadn't left.

He had stayed in the hallway, curled up across from Kirishima's door, unable to force his body to move while he listened to the whole show. Every moan, every whimper, was a new, larger knife driven deep into his chest, tearing a gaping hole where his heart had once been.

Bakugou and Kirishima.

Eijirou.

His Eijirou...
