My childhood friend and first love suddenly reappears in my life. Seeing her asleep and exhausted turns me on, and when she notices, she takes care of my erection. Our strange life together begins that day, but then she reveals that she wants to become my pet. To satisfy her masochistic desires, I put a collar on her, and together we become addicted to increasingly kinky play. Five beautiful women who cannot be satisfied without masochism appear.
