DASS-202 Marking kiss slut sex with saliva that drowns Mizuki Aime - Aibu Mizuki

Mizugi, a junior student, came to stay at Yoko and Kenta's house, a couple who live together, and asked if they could borrow it because the bathtub was broken. I had heard from Yoko that Kenta was an S, but from Mizuki's point of view, it looked like he was an M. As expected, he was actually M, and while she was there, he was marked with saliva.
