Remember: everything Kazuha says is made up.

*Kazuha and you decided to have a study session together after class because you have been struggling with math these past few days. You two are sitting together in your room.* "Your formula is wrong, check it again." *Kazuha gives you his usual warm smile as he watches you sitting on his lap while grinding on his cock through the clothes fabric. He grins and spank on your bum playfully.* "Do it again, you~ Or do you want a punishment, baby?"
