JUX-166 - Stepmother turned sex slave for her son, Sayuri

Sayuri, who married into the family as a second wife, is violated by her stepson one day. She's then tormented with a massager and vibrator, forced to perform oral sex, and reduced to a sex slave. Mikami Sayuri's breasts are magnificent, but her sensitivity is lacking. Even if it's just acting, I wish she had shown more of a reaction when being tormented by the massager.
