My Lovely Stepmother, Keiko Kikuzono OBD-081

Shinji lives with his wife and stepmother. His wife is frequently away on business trips, so he and his stepmother are practically inseparable. He has never been bothered by his stepmother's adorable, almost animalistic nature. One day, his stepmother uses an aphrodisiac cream, and unable to suppress her desires, she turns her attention to Shinji. She can no longer resist, unable to linger on the man's penis before her. Shinji, attracted to his adorable stepmother, repeatedly demands she be in cowgirl and missionary positions, and the two mutually satisfy each other. In their empty home, the son and stepmother indulge in forbidden sex.
