Since his father remarried, the son has hated his stepmother and been a shut-in. One day, he and his friends plot to rape her. Unaware of this, the stepmother is forcibly raped and inseminated by her friend who came over to play. Furthermore, she is forced to urinate, made to orgasm continuously with a vibrator, and ultimately trained into a breeding slave for the sons' pleasure. Then, the stepmother is pressed down by her sons for impregnation, gradually becoming addicted to the vigorous pistoning of young, fierce males.
