A mother troubled by her son's insatiable sexual appetite turns to her childhood friend, a notorious womanizer, for help. But the boy she thought was just a naive virgin turns out to be capable of intense, relentless thrusting, bringing her son to climax over and over again. His desire knows no bounds—he masturbates at least ten times a day without fail. Riding him hard with furious cowgirl-position sex, she tries to drain him completely, yet her actions end up triggering his transformation into a full-fledged sex monster. There's a terrifying possibility here: if this continues, the womanizer's reputation might be destroyed instead.
