SSIS-699 I've been slipping aphrodisiac into my stepmother, who is four years older and has large breasts, every day for seven days. On the seventh day, she became a lustful bitch craving incestuous sex. Sakura Okuda.

His father remarried and his new mother was only four years older than Hajime. Hajime was always lusting after her new life living with her young girlfriend's mother-in-law, Saki, and her beautiful, big breasts and youthful body. Hajime, who attends the university's pharmacy department, mixes the things he obtained from her and secretly administers them to Saki as an aphrodisiac. A few days passed and a change appeared in her Saki's body... I was so desperate for the body of my young stepmother...I devoured Saki, who had turned into a wild slut with an aphrodisiac, every day.
