There was a reason why the so-called Ria Mitsuru Hashimoto was on good terms with the introverted Ryota. That’s because I wanted to rape Ryota’s mother, Mai. A plump body that can be seen even from the top of the clothes … And, contrary to the flashy appearance, the chaste place made me feel more black. One day Hashimoto hears Mai calling her husband. Apparently Mai is lonely because she can’t easily meet her husband who is busy with work. When Mai hangs up, she begins to comfort her body without noticing Hashimoto’s existence.
