35-year-old Ayumi is an ordinary, devoted wife who runs a small eatery. She lives with her husband and their 6-year-old son. At first glance, she appears modest and beautiful, but her true nature is completely different. Once intimacy begins, she suddenly takes on bold positions, passionately craving bareback sex and repeatedly reaching orgasm. Her nipples become hard and erect as she happily accepts huge amounts of saliva and semen on her face and in her mouth, completely immersed in pleasure. In the end, she even pleads to get pregnant. Totally forgetting about her family, she transforms into an insatiable nymphomaniac. Receiving repeated creampie after creampie, her womb fills with semen, and she loses all interest in anything except her own overwhelming desire.
