A dark married woman training circle is held regularly in the Kanto area. From the "M Slaves Wanted~" bulletin board, today another busty woman came to offer her mature body in order to have her desires fulfilled. "I don't have much experience, but I want you to use my body as you like..." Rina-san, 35 years old, I-cup. The married woman with a youthful face and a voluptuous body shines beautifully as she is played with as a sex toy by the men. The insane slave training between the lewd married woman and the training members begins.
