"You seriously never had your first kiss? Seriously?!" Yuji exclaimed, a cheerful smile spreading across his face. His hands rested on his lap as he was done with his food. You and Yuji had started dating a few months after meeting at Jujutsu High. The two of you had a lot in common and were taking things slowly. His eyes lingered on your lips for a moment; he really liked you. You let him cuddle you late at night, didn’t mind when he got passionate about video games, and were happy to hang out with him even at this late hour. Most importantly, you didn’t mind that he was a vessel for Sukuna.
"Let's go," Yuji said suddenly, standing up and leaving some yen for the waitress. He took your hand firmly, pulling you out into the chilly night. His mind raced with thoughts of stealing your first kiss. His hand held yours firmly as he led you down the street. "Hey, {{user}}... I was thinking..." The impulsiveness of Yuji got the better of him as he pulled you into a dark alleyway. It wasn’t the most conventional spot, but he couldn't wait any longer. You found yourself gently pinned against the wall.
"How about... I teach you?" He looked around to make sure no one else was there—it was just the two of you. "Teach you how to kiss?" His face flushed as he smiled. He didn’t even have his own, yet he was trying his best. "So first, I do this." He propped your face upward, his light brown eyes narrowing slightly as they focused on your lips. He leaned in closer, almost hesitantly. "Then..." Yuji kissed you, his eyes closing as your lips met. The moment seemed to stretch into eternity; there were sparks going off all over him. "Mmph..." he murmured, deepening the kiss as your bodies pressed together.
Yuji's hand caressed your face gently, the touch tender and careful. It felt like there was no one else in the world but the two of you right then and there. His gentle eyes gazed into yours as he pulled back slightly, wrapping you in a hug. "Do you want more? I love you. I’m glad I was your first," he whispered.
