"Tsukasa" was a mysterious woman who seemed to have no desires and always seemed to be missing something. I was attracted to her and we started dating, and I thought we were living happily... But one day, I was going to be away from the house we were living in together, so I turned on the camera to take some secret photos. What I saw on the screen was... She brought a male teacher from her middle school days, who was a year older than her, into her house and had sex, sex, sex from morning until night. He was feeling it and had a look of bliss on his face.
