In front of my best friend, I have sex with his girlfriend in the kotatsu so that no one will find out! I try to hold back my voice and endure the pleasure, but it feels better than usual and her pussy is soaking wet that a state of emergency is declared! The more I think about how dangerous it would be if I were found out, the tighter her pussy tightens and I can't hold back and cum inside her! Unable to hold back any longer, she seeks me out next to her sleeping boyfriend, and we have sex with each other, with a sense of immorality at its maximum, in a situation where neither of us can make a sound! Women are scary...
