One day, my boyfriend's best friend, Tatsuya, came to the house where we were living together. - I was drinking too much...maybe I was feeling relaxed. - In front of Tatsuya's sleeping eyes...I ended up having sex with my boyfriend as usual. - The thought that someone might be watching me made me even more excited, and even though I knew it was wrong, I couldn't stop myself. - A record of creampieing with my boyfriend's best friend for four days when my boyfriend was away.
