The son is increasingly afraid to face his stepmother, who recently became a part of the family. Whenever she has free time, she relentlessly teases his cock, stopping just short of climax, taking pleasure in his pained expressions. Moreover, she forbids him from masturbating, forcing him to promise that he'll only ejaculate in front of her. Even today, after being tormented endlessly, she mounts him and treats his raw cock like a tool, riding him with intense thrusts, leaving him helpless. Finally, when he's allowed to ejaculate, he's filled with a torrent of cum deep inside her pussy.
