"No way..." Noticing his cleavage, he secretly had sex with his friend's girlfriend. (Aizawa Tsubasa KAWD-602)

I was temporarily staying at a friend's and her boyfriend's house. I got lustful and secretly peeked into their room and bathroom, witnessing them having very affectionate sex and masturbating with their fingers inserted. I thought to myself, "I'm so envious of them, I'll have the chance to visit soon." We drank at home and both got drunk... with my friend sleeping next to me, I went all out and started rubbing him! It led to drunken sex! After that, it became a terrible situation where my girlfriend came to me for sex... "I can't forget your penis." Although I felt bad for my friend, it became the best memory.
