Recently, my wife Ichika's behavior has become strange. While sleeping together, she suddenly starts convulsing, has nightmares about someone appearing in her dreams, doesn't answer her phone more often, and comes home later than usual. Growing suspicious about what might be going on, I secretly installed a hidden camera in our home. When I returned from work and checked the footage, I discovered someone entering our house in the afternoon—it was the doctor from the health examination she had attended together with me. The doctor told her, "Sensei, my nipples feel like they're burning hot..." and then proceeded to pinch her erect nipples, making her scream out in shock and pleasure. Seeing Ichika's condition, I grow increasingly anxious, wondering what else she might be hiding from me.
