A married woman pushing a stroller is pursued in an attempt to take the 'postpartum virginity' of a woman who has just given birth! When you pry open her tightly closed legs, she comes repeatedly! Even though she was resisting, the pleasure she felt after a long time made her legs tense up and her lower abdomen ripple! Once she cums, the trembling convulsions won't stop! When a man's cock penetrates her vagina, which has shrunk after childbirth, the pain soon turns to pleasure... and the child-rearing mother's Kokoro to cheat awakens!
