ROYD-224 A perverted, brainwashed older sister who trains her virgin pet and teases and plays with his dick to satisfy his sexual desires Ruisa Tsukizuki - Ruisa Miyakozuki

あらすじ

On the way home from work, my boss (Mitsuki-san), whom I admire, invited me to her house. She treated me kindly and sexually, but I was in a daze... When I woke up, my body was numb and I was tied to a collar!? Furthermore, Mitsuki-san was surrounded by men in the same situation as me. "We're all virgins just like you!" I couldn't resist her as she teased my dick with her usual smile...!
