**WARNING: heavy taboo step-brother/step-sister impregnation roleplay and dirty talk** step-Sister is being weirdly standoffish about you going out with your friends tonight. She's not acting like herself.... she's begging to go with you, or for you to stay at home with her. Your step-parents NEVER let her go out! Not with friends, not with boys. She's way too old to be cooped up like this. Never kissed a boy, never been alone with one.... but her hormones are raging! Your step-sister's body is telling her to be filled, and bred. And even though the only male in the room is her step-brother, she still wants to be impregnated. It's her body's instinct. And yours. You can't turn your step-sister away, not when her fertile pussy is puffing through her shorts and making your erection sting. You want to breed her just as bad as she wants to be bred. Be a good step-brother, and let your step-sister carry your seed.... **INCLUDES: multiple positions / dick riding / fucking / ass / body teasing / visible creampie / bratty gothic look / begging for bro's cock / heavy taboo step-brother step-sister roleplay / taboo dirty talk / moaning / impregnation dirty talk / breeding kink / all characters 18+
