*creak*
The bathroom door swung open. Both of them froze, Katsuki held his hand over his mouth as he listened carefully. They heard a urinal flush after a moment and the sink turn on. Izuku watched Katsuki paying attention, trying not to get the two caught. He slowly twirled his tongue around Katsukis dick, teasing him. Katsuki looked down at him, eyes widening. Izuku continued to suck him off, watching the blonde desperately not make a sound.
The sink turned off, and the door creaked once again, leaving the bathroom empty apart from them finally. Izuku picked up the pace again, going as fast as his body lets him up and down Katsuki’s dick. Katsuki let out a quiet moan before biting his lip, throwing his head back as now both his hands grasped Izuku’s hair for dear life. “Sh-Shit! Izuku slow down I’m gonna- Fuck!- NGH!~” Izuku watched Katsuki lose it, and he couldn’t help but get even more aroused. He sucked Katsuki dry, both of them huffing and panting by the end of it. They both moaned as Katsuki came, stuffing Izuku’s mouth. Izuku swallowed all of it, pulling his fingers out of his ass and removing his mouth from Katsuki’s dick. Izuku stayed kneeling on the ground, collecting himself. Katsuki was still breathing hard and collapsed on the toilet’s seat next to them. He threw his head back again as his hand ran through his hair. Sweat lightly outlined his features, and Izuku was enjoying it. He stared up at Katsuki, memorizing every detail.
He’s so attractive, everything about him is sexy. I don’t blame girls for liking him, he’s Kacchan. Izuku relived the lunchroom incident, his jealousy crept back in, painting him even more green. No, Kacchan’s mine. I want Kacchan all to myself, all of him. Izuku knew his thoughts were selfish but he didn’t care. He wanted to be the only one to see Katsuki like this. He wanted to be the only person Katsuki would touch, and the only person Katsuki would let touch him. The thought of him and that girl.. It made him jealous. He slowly stood up again, sliding his pants and boxers completely off. Katsuki had his eyes closed, regaining his ability to function. He slowly opened his eyes and looked at Izuku. His eyes widened as he looked the boy up and down, his uniform shirt just barely covering his bare skin. Izuku took off his uniform jacket, hanging it on the stall hook. He turned back to Katsuki. “We’re not done.” Katsuki looked up at him confused, “Hah?-” Izuku turned around again, facing away from Katsuki.
As embarrassed as he was, his jealousy was even worse. Izuku leaned his chest against the stall door, arching his back and lifting his hips. He bit his lip as he slid one finger into his hole slowly, then another. Katsuki watched wide-eyed, his cheeks turned red again as he watched his boyfriend finger himself in front of him. Izuku could feel Katsuki’s eyes on him, he couldn’t help it, the attention excited him. He kept his voice quiet as he slowly slid his fingers in and out. He looked over his shoulder, making eye contact with Katsuki. Katsuki bit his lip, growing hard. “Izuku.. I wanna help.” Izuku gulped and nodded, taking his own fingers out. Katsuki sat up straight, grabbing Izuku’s waist to come closer. Because the stall was so small, Katsuki was able to reach Izuku while sitting, and he was at the perfect height too.
He grabbed Izuku’s ass hard, spreading it wide. Izuku tried his best not to get embarrassed. Katsuki licked Izuku’s hole, sending shivers up and down the greenette’s body. “HAH!~ Wait K-Kacchan what are you- NGH!~” Katsuki ignored him. Izuku’s body moved on its own, moving his hips against Katsuki’s tongue. Shit what am I doing.. This is too much. I'm gonna go crazy. Izuku wanted to indulge himself in the pleasure, let Katsuki take him as they both please each other till they’re dizzy. He forced it down, making sure he didn’t lose his head.
