Yumi has a youthful, girl-next-door look and already has children, but she seems confused about married life and appears to be suffering from serious sexual frustration. When she meets up with her fuck buddy, things get incredibly wild—so intense it's like entering another world. In this shocking release, her sex sessions are secretly filmed without her knowledge and then sold commercially. It's a great deal just getting sex for free, but to have it filmed and sold as a product without consent feels almost like a professional operation.
