Three stories of Aoki Kashimoto's huge boobs. 1. Gynecologist treats frigidity! Inter-femoral sex is so pleasurable that it even requires penetration! 2. A massage parlor specializing in boobs. She asks for advice on her stiff shoulders, but for no apparent reason, she is stripped naked and given an erotic massage! 3. Breast enhancement exercises. Jumping rope, spinning hula hoops, playing balance ball, chest shaking vigorously.
