I was unknowingly seduced by a female friend who had a boyfriend who came to stay over every day, and I couldn't muster up the courage to do so.

After starting university life, I finally found a life on my own. I was supposed to enjoy free masturbation time without being disturbed by anyone. However, for some reason, the person who comes to stay at my house every night is Kiho, a female friend who has a boyfriend. At first I thought it was just a whim, but she didn't come home even after the weekend. A relaxed smile, a nightgown that is too defenseless, and a meaningless body touch. --Every time I tell myself that that's not my intention, I feel a commotion in the back of my mind. But nothing is happening. I can't wake you up. Late at night, while she's asleep, I secretly start masturbating, but when she finds out, we have sex. I skipped school over and over again... "Can I stay over tonight?"...I didn't feel like I could say no anymore.
