My wife, who started working part-time at a local company, would occasionally invite her coworker, a young man in his twenties, over to our house to discuss shifts and chat with him, deepening their communication. I felt uneasy, so I set up a camera in our house without telling my wife... While my wife, who enjoys fitness as a hobby for health and beauty, was practicing stretching, the coworker's erection was getting stuck in her crotch...!
