My best friend's mother is a virgin killer ☆

Reiko hears a conversation between her son and her best friend Tatsuya, who is leaking out of her room, and finds out that Tatsuya is still a virgin. Reiko, a carnivorous woman whose sexual instincts are flapping up thanks to her everyday frustration, tries to get her first cock when her son is standing in the bathroom, but Tatsuya quickly explodes with Reiko's incredible technique. Reiko is depressed when she sees Tatsuya running away from the scene with embarrassment and humiliation... That night, Reiko appears in a bondage suit as Tatsuya's dream pillow, who can't forget what happened during the day.
