A woman who visited a doctor for pelvic correction due to her complex about having a large butt became the target of a perverted physician. Claiming to know an acupoint that makes butts smaller, he performs erotic massages on her. As her sensitivity increases, she blushes with shame, unable to suspect that this is anything but a normal massage. Eventually, she is made to lie on her back and has her hip bones and pubic bone touched, experiencing sensations as if her uterus is being stimulated from outside, causing her to twist her body and kick her legs... Women who experienced vaginal orgasms for the first time feel immense pleasure.
