After several happy years of marriage to Sara and steady success running a small company, my only headache was Yoshino, a junior employee who constantly slacked off. Thinking marriage might straighten him out, I invited him home for a three-hour mock-marriage experience alone with my wife. He seemed to learn the appeal of married life—but when he asked to visit again a few days later, I planted a hidden camera as a joke. What it captured was my wife being relentlessly fucked and creampied 16 times without him ever pulling out, turning my lesson into the story of how he stole her from me.
