One day, my wife suddenly left home. My phone rang, and I heard her voice together with another man's. I rushed to the man's place, but the door was locked. All I could hear was my wife moaning inside. While begging for forgiveness, my body grew hotter and hotter, excitement becoming uncontrollable. Facing the sexual act happening right before me, the sight of my wife greedily indulging in pleasure made me want to masturbate more than feeling guilty. The frustration of touching myself alone only heightened my arousal even further. Later, I received a video from that man, showing my wife completely consumed by lust—an entirely new kind of stimulation unlike anything before. Yet, it couldn't compare to the thrill I felt that day. Now, I'm desperate to relive that sensation once again.
