VENX-150 I have long-distance sex with my son who moved to Tokyo once a month. This month, I'm going to let that kid fuck me again──. Kuroki Miia

Worried about her son who came to Tokyo to attend college, his mother Mia goes to take care of him once a month. However, as she goes to school many times, her affection for her child goes beyond family love and develops into a relationship between a man and a woman. "I can't let this happen to me, even though I'm a parent and child. But I can't change the fact that I love that child. What should I do...?" I can not stop my aching body and decide to go to Tokyo again.
