My wife, who started working part-time at a local company, would occasionally invite a young man in his twenties who was also working part-time at her place over to their home to discuss shifts and chat with him, deepening their communication. I felt uneasy and 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 part-time worker got an erection in her crotch, which was digging into her...!
