A woman (23) working at a girls' bar in Toyoshima, Tokyo. In her student days, she had a very sadistic male university tutor who would punish her for giving wrong answers or forgetting her homework. She was sometimes made to strip, spanked on the buttocks, had her nipples pinched with clothes pegs, and even bound with hemp rope. It's said that she's now captured her incredible perverted behavior on camera. Please take a look at the real deal of this true, genuine perverted, large-breasted masochistic woman who, when bound with hemp rope in front of many men, squeezes her body so tightly that her uterus aches and she lets out ecstatic groans.
