[Mosaic removed] Yokoyama is at his wife's parents' home when she is about to give birth, and is attracted to the voluptuous body and behavior of his sister-in-law Minami, who has grown into an adult woman, and is disturbed. He is looking forward to peeking at Minami with the camera he borrowed in the name of her crime prevention, but he witnesses Minami's lewd appearance as he takes her male subordinate into the room and devours her pleasure by shaking his hips. Her desire, which she had suppressed, began to swell... A must-see for Madonna's first appearance, the popular big-breasted actress Minami Ayase, who feels the pressure while resisting the pressure!
