A beautiful young boy who was born as the head of a family with a long history. Rei, who has been cherished and raised by everyone around her, has a pitiful masochist soul that can't help but go on a rampage... "I want to be the lowest class prostitute. Rather, I'd rather get even a small price." I want to be a sex slave who can't be beaten..." Rei, who continued to have such thoughts, finally transformed herself into the body of a livestock. At the center of the masochistic remodeled body, the penis reacts to the bondage and bends, and when its towering is trampled, the pain and humiliation will make you intoxicated with ecstatic pleasure. Please take a look at Rei's appearance as a masochist who is overrun by a man's lust and falls into a horny meat urinal.
