ship: katsuki bakugo + eijiro kirishima - aged up (3rd years in UA)

"Hey, Shitty Hair, wait up!" Bakugo's voice echoed through the empty hallways of U.A. High School. 

Kirishima glanced over his shoulder, his cheeks tinting a faint shade of pink as he slowed down. "What's up, Bakugo?" He hoped his voice didn't betray the hammering of his heart.

Bakugo's eyes narrowed, a smouldering look replacing his usual scowl. "I need to talk to you about something." He grabbed Kirishima's wrist, pulling him into an empty classroom. The door slammed shut with a finality that seemed to echo through the room. Kirishima's eyes widened, but before he could protest, Bakugo's mouth was on his, hot and demanding.

The kiss was a surprise, but not unwelcome. Kirishima's body responded instinctively, his arms wrapping around the explosive teen's waist. Their tongues danced together, a fierce and passionate duel that spoke of months of pent-up frustration and desire. Bakugo's grip tightened, his hand sliding down to cup the back of Kirishima's neck, guiding him deeper into the kiss. The classroom around them faded away, leaving only the scent of sweat and the sound of their ragged breaths. Kirishima felt his knees wobble slightly, his body responding to the sudden onslaught of sensation. He hadn't realized how much he had craved this, how much he had missed the feel of Bakugo's hands on him. His mind raced with the sudden reality of their situation, but his body was already moving in response, pressing him closer to the boy he had once considered his friend (with benefits) but to Kirishima in this moment it felt like it was more.

Bakugo's hands roamed over Kirishima's body, exploring the contours of his muscles through his school uniform. His palms felt like fire against Kirishima's skin, leaving a trail of heat wherever they touched. Kirishima moaned into the kiss, feeling his body grow hotter and more responsive with every passing second. He could feel the bulge in Bakugo's pants, a clear indication of his arousal, and it only served to fuel his own desire.

With a rough tug, Bakugo pulled away, panting heavily. His eyes were dark and filled with a hunger that sent a shiver down Kirishima's spine. "Take off your shirt," he ordered, his voice low and gruff. Kirishima complied, his fingers trembling slightly as he unbuttoned his shirt and let it fall to the floor. He watched as Bakugo's gaze devoured him, taking in the expanse of his bare chest and the muscles that rippled beneath his skin.

The explosive teen stepped closer, his own shirt already discarded. His hands traced the lines of Kirishima's abs, his touch feather-light yet leaving a trail of fire in its wake. Kirishima could see the excitement in Bakugo's eyes, the way they lit up when he found a particularly sensitive spot. He leaned into the touch, his own hands gripping the edge of the desk for support. "God, you feel so fucking good," Bakugo murmured, his voice a mix of awe and need.

Kirishima's breath hitched at the words, his body responding eagerly. He knew that this was the moment of no return, that once they started, there would be no turning back. But he didn't want to. He had been waiting for this, dreaming of it, for what felt like an eternity. "I want you," he whispered, his voice hoarse with desire.

Bakugo's smouldering gaze met his, and for a brief moment, the air between them was charged with an intensity that stole their breath away. Then, with a growl, Bakugo closed the distance between them, his hands sliding around to unbuckle Kirishima's belt. The sound of the zipper was like a gunshot in the quiet room, a stark reminder of the passion that was about to unfold.

Kirishima's pants fell to his ankles, and he stepped out of them, his heart racing. He could feel his cock, hard and eager, pressing against the fabric of his boxers. Bakugo's eyes dropped to the prize before him, and he licked his lips, a wicked smile playing on his mouth. He reached down and slid his hand under the elastic, gently pulling the boxers down to expose Kirishima's erection. "Fuck," he breathed, his voice filled with lust.
