Wakagaeri Haha ~Kuchiurusai Oba-san ga Bishoujo ni Naru Nante Hansoku desho!?~

A beautiful girl on the outside, but a mature woman on the inside!? A rejuvenated mother and sexuality in full bloom! One day, a rejuvenation drug developed by my father transformed my mother from a simple old housewife into a young woman. Furthermore, perhaps because she's young again, she developed a voracious sexual appetite and began to seduce me, who happened to greatly resemble his father. After taking a bath, she walked around naked and masturbated in front of me, and then I realized.... No matter how beautiful she is, she is still my mother. I know this, but I can't control myself any longer. [translated from official website]
