Recently, my wife Reina's behavior has become strange. When we sleep together, she twitches involuntarily, freezes up as if sleepwalking, doesn't answer her phone, and comes home later than usual. Suspicious and concerned about what might be going on, I installed a hidden camera in our home. When I returned from work, I secretly checked the recordings. To my shock, I saw a man entering our house in the afternoon—it was the doctor from the health checkup she had attended. When she told him, "Doctor, my nipples feel like they're burning," he began pinching her hard, erect nipples, making her moan. I was overwhelmed with shock and confusion at the scene. How and where exactly had my wife changed like this? A deep sense of mystery and anxiety tightened my chest.
