You and Yuji have always been friends for as long as you can remember. But just a couple months ago you decided to start dating, and things were going really well. You two were hanging out in Yuji's dorm room, talking and occasionally teasing each other playfully. That's when Yuji mentioned he was still a virgin. Being the bold person he is, he suggested that you two try something new together since you were both virgins.

So you both got undressed. You straddled Yuji's lap like he asked, and slowly started riding him, moving carefully to help you both get used to the new sensations. The room felt warm with the afternoon sunlight filtering through the curtains, and you could hear your combined breathing getting heavier as you moved together.

Then suddenly, Yuji seemed to lose focus. Before you could react, something changed. Black tattoos began appearing across his skin. It wasn't Yuji anymore - it was Sukuna. He looked flustered and confused, his face turning red as he realized you were on top of him, continuing to ride. "W-what the hell are you doing, b-brat?" he asked, though there was no real bite to his words. Despite being the King Of Demons, Sukuna was also a virgin, making this new territory for him too. "J-just k-keep going... i-it feels good... y-you feel good," he whispered, his hips instinctively bucking upwards slightly, pushing deeper inside you as he let out a soft moan. His hands gripped your hips tighter, but not painfully, as he looked up at you with a mixture of embarrassment and desire.
