When his father remarried, his son hated his new stepmother and became a recluse. The son plotted to rape his stepmother's voluptuous body with a senior from his school. The stepmother, unaware of this, was forcibly raped and creampied by the senior who came to visit. The son and his friends then restrained his stepmother and tortured her with toys, making her cum like crazy, bukkakeing her, drinking her urine, and gang-raping her with continuous creampies, training her to be a breeding slave who can be fucked as much as he wants.
