Îmi fut sora vitregă în cur în schimbul unei pule pentru a o lăsa să iasă cu noul ei iubit

My stepsister asks my permission to let her go see her boyfriend, I am jealous of her because she is the only one who can have sex with me, therefore I tell her that I will let her go out in exchange for her making me cum in her ass, which she agrees to and earns permission.
