In this adult sibling role-play, a brother who impregnated a yakuza man's wife calls his older sister for help after disappearing. “Pay for your brother's betrayal with your body,” the gangsters tell her before imprisoning her and vowing not to release her until she is pregnant. Treated like a sex slave, she is raped and creampied in front of her brother, collared, repeatedly bred, and forced to serve the men day and night. They even force the adult siblings into incest before them, while her body keeps climaxing against her will.
