UMSO-573 My girlfriend is a perverted masochist - Sachiko

My childhood friend and first love suddenly appeared in front of me. I was aroused by the sight of her sleeping, tired. She noticed and comforted me. From that day on, we started living together in a strange way, but she said she wanted to be my pet. I put a collar on her to satisfy her sexual desires, and she became addicted to perverted acts... Five beautiful women who can only be satisfied by masochism are featured. Enjoy!
