Three stories of Rin Aoki's huge breasts. 1. A gynecologist treats her frigidity! She finds the intercrural sex so pleasurable that she asks for penetration! 2. A massage parlor specializing in huge breasts. She visits for advice about her stiff shoulders, but for some reason she is stripped of her underwear and given an erotic massage! 3. Breast exercises. Her breasts sway powerfully as she jumps rope, uses a hula hoop, and uses a balance ball.
