Uruha Tanaka, 36-year-old mother of two. Boasting an outstanding K-cup with an overwhelming 115cm bust, her extra large breasts immediately drew attention in her debut. Back in her single days, many men were attracted to her, from whom she eventually chose her current husband. However, after marriage, she never experienced the kind of sex she desired and has built up considerable stress. Her husband is satisfied merely with nipple stimulation and sticks exclusively to missionary position, leaving her without ever having achieved an orgasm from intercourse. Now, on the 10th anniversary of their marriage, she has reached her limit. Determined to experience the ideal sex she craves—filled with passionate full-body caresses and culminating in internal orgasms—she steps forward to take on this challenge. Watch her journey unfold.
