The Younger Stepmother Who Married My Respected Father Was a Sadistic Ejaculation Controller. Mao Hamasaki

Living with his stepmother gradually darkens the son's mind. Her actions constantly stimulate his body, forcing him into daily agony. Whenever she has free time, the stepmother aggressively plays with her son's penis, robbing him of all pleasure. These acts are unbearable for him, and he's forbidden from masturbating in her presence, forced into an impossible promise to only release his semen inside her. Again today, unable to endure her assault, he finds himself pinned beneath her as she straddles him, violently grinding her hips and using his bare penis like a tool, leaving him helpless. Finally granted permission to climax, the son erupts a massive load deep into his stepmother's vagina, experiencing both intense pleasure and pain at once.
