Six months after childbirth, the sensitive beauty Tsubomi has avoided sex. At her husband's suggestion, she visits a postpartum massage therapist, but writhes in agony as oil is applied right up to her groin, moaning uncontrollably. Overwhelmed by pleasure, she loses her postpartum virginity. Her body, now far more sensitive than before childbirth, cannot withstand the intense stimulation pounding her uterus—her convulsions won't stop. Her abs twitch violently, engulfed in prolonged ecstasy. The highlight is this elegant young wife spreading her vulgarly wide legs, squirting repeatedly as she orgasms uncontrollably over and over. Obsessed with postpartum sex, Tsubomi seeks out the masseur again, chasing new pleasures even while her family is at home.
