Minori-san, 35, became a masochist after giving birth. At home, she is sexless and meets men on dating sites to satisfy her sexual desires. She met a man and had a light bondage play, which opened up an abnormal world. Minori-san was bound and humiliated with bondage training and shameful masturbation, nipple teasing with clothespins while bound to a pillar, and milk dripping while she came repeatedly. Further, she was violently stimulated with internal massage until she received a mouthful of semen! She was hung sideways and vibrated until she came repeatedly. She was bound in a crouching position and teased with candles, then had sex while bound. Minori-san came repeatedly while crying.
