Mizuki Fukuyama, 45, is an elegant woman with a sophisticated short haircut. While working as a library librarian, she leads a leisurely life, enjoying visits to art museums on her days off. With her graceful demeanor, she seems like the quintessential virtuous housewife, but in reality, she possesses a hypersensitive body that can reach climax just by having her nipples kneaded. Her husband is appalled by her unexpected intensity, and after their second child was born, their sexual activity dwindled to just once a week. "I'm so embarrassed that he's put off by me, that I can no longer give my all to my husband..." With no one to talk to about her frustrations, her desire only grows. She truly wants to drown in pleasure and reveal her truly slutty side. Witness the full story of this overly delicate housewife as her hypersensitive body trembles, drowning in ecstatic, unfaithful climaxes!
