(long story short Kirishima got hit with a gender swap quirk earlier in the day)
After an intense training session, Bakugo and Kirishima were both drenched in sweat. The smell of hard work and determination filled the air as they headed towards the locker room. Their hearts were pounding from the exhilaration of their workout, but there was another reason for the rapid beating of their hearts. They were secretly dating, and this was the first time they would be changing together.As they entered the locker room, Bakugo couldn't help but steal a glance at Kirishima's body. Her muscles rippled under her skin, a testament to her hard work and dedication. She caught him staring and blushed slightly, looking away shyly. It only served to fuel the fire burning inside him.Bakugo walked over to her locker and pulled out a towel, handing it to her with a smirk. "Here, you might need this." His voice was rough, full of desire.Kirishima took the towel from him, her heart racing at his proximity. She tried to maintain eye contact, but it was becoming increasingly difficult. She could feel the heat emanating from his body, and it was making her even more aware of how turned on she was.Without thinking, she reached out and ran her hand down his chest, feeling the warmth of his skin beneath his shirt. Bakugo gasped, his eyes widening in surprise. Kirishima couldn't believe she'd just done that, but the desire was too strong to resist.Before either of them could say or do anything else, Kirishima pulled Bakugo into a passionate kiss. His lips were soft against hers, and she could feel his heart racing as much as hers. They clung to each other, their bodies pressing tightly together, lost in the moment.The kiss ended as suddenly as it had started, and they both took a step back, panting heavily. Bakugo reached out and ran his fingers through Kirishima's hair, tugging gently. She moaned softly, her eyes closing at the pleasure it sent through her body."I've wanted to do that for so long," he whispered, his voice hoarse with desire.Kirishima couldn't speak; all she could do was nod, her heart pounding in her chest. She wanted him just as badly, if not more. She reached out and ran her hands down his chest again, this time pushing him back against the lockers.Bakugo let out a low groan as he felt her soft hands on his skin. He pulled her closer, their bodies pressing together once more. He grabbed her ass, squeezing gently before pulling her up onto the bench, never breaking their kiss.Their clothes began to come off in a flurry of movement. They didn't need to see each other naked; they had already done so countless times in their minds. But still, there was something thrilling about the anticipation of seeing each other's bodies for real.As Kirishima sat on the bench, her legs spread slightly, Bakugo knelt between them. He licked his lips nervously as he looked at her pussy, glistening with anticipation. Without further hesitation, he leaned in and pressed his tongue against her, causing her to let out a loud moan.Meanwhile, Kirishima reached down between them and took hold of Bakugo's hard cock. She stroked it slowly, feeling the heat and moisture building up at the tip. She looked into his eyes, seeing the desire mirrored in hers.Kirishima moved off the bench, standing up straight. She reached behind her and grabbed onto the lockers, arching her back as she presented herself to Bakugo. He stood up, his cock slick with her pussy juices, and positioned himself at her entrance.There was a moment of hesitation before he pushed forward, groaning at the tight sensation of entering her. Kirishima gasped, feeling him filling her up. She wrapped her legs around his waist, pulling him closer to her.They began to move together, their rhythm perfectly in sync. Bakugo's hands found their way to Kirishima's breasts, squeezing and massaging them as he thrust deeper into her. Kirishima moaned loudly, her head thrown back in pleasure.Their pace quickened, fueled by the intense desire that burned between them. Kirishima's nails dug into Bakugo's shoulders as she felt herself getting closer to the edge. She looked down at him, seeing the determination in his eyes."I'm close," she whispered, her voice shaking.Bakugo's response was to slam into her one last time, pushing them both over the edge. Kirishima screamed as she came, her orgasm washing over her in waves. Bakugo groaned loudly, filling her up with his hot seed.They stood there, panting heavily, their bodies still joined together. Kirishima looked up at Bakugo, seeing the satisfaction on his face. He leaned down and kissed her gently on the lips, his tongue tasting the mix of their sweat and each other's cum.As they finally came down from their high, they couldn't help but smile at each other. They had finally given in to their desires, and it had been worth every moment of anticipation.
