Ryoubo Sayuri ~ Miboujin no Inraku Houshi

Sayuri was a young woman who lost her husband.
Her daughter worked as a live-in caretaker at a bachelor's hostel.
One day she collapsed in exhaustion, and Sayuri was asked to help out in her absence.

A welcoming party was held for Sayuri by the tenants, and the gentle beauty got drunk and fell asleep.

When she awoke, Sayuri's hands and feet were pinned down and hands were crawling up her skirt and into her blouse. She suddenly realized what was happening, and why her daughter
had collapsed. And like her daughter, Sayuri was being tied up and sexually devoured.

She resisted, terrified, outraged... but there was a pleasure too...
