I was unconsciously seduced by a colleague with a boyfriend who comes to stay overnight every day, and I couldn't get the courage to die.

My apartment, which I lived alone right next to my office, has become a hangout for friends. One day, a friend brought her to me, and I met Kana-san. She began to spend more time in my apartment and slept in small groups while meeting up with friends. Although I can't put my hands on her, when I'm asleep, I can't hold back and masturbate secretly... Then she wakes up and gives a blowjob! I was in a state of frustration and I, and I was still going strong and I could finish...! Since then, I forget that my boyfriend exists and end up having sex. Kana-san says she's going to do something about her going to her boyfriend...
