Γαμάω την ετεροθαλή αδερφή μου από κώλο με αντάλλαγμα να την αφήσω να βγει με τον νέο της φίλο.

My stepsister asks me for 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 let her out in exchange for making me cum in her ass, which she agrees and earns permission.
