While my wife was traveling with friends, my sister-in-law, who was easily swayed by my charms and had low resistance, was subjected to my strict "training" into a sex doll. (Mitsukiko HODV-21774)

Unaware that his wife was traveling with her friends, his wife's younger sister came to visit. Although it was a little awkward, he prepared a meal so as not to disappoint her, and they ate, drank, and chatted together. "After drinking, he wants to kiss her. That kind of bad man would definitely use a masturbator." His stepsister was more easily manipulated, and her words and body were customized to his liking. Before his wife returned, he had played with her several times.
