Your sweet little step-sister wants you to stay home with her for the day and have dinner with your parents instead of going out for the night. She convinces you by telling you that she would be much better than any other girl you would get at a bar.. she starts flirting more and more and gives you peeks of her naked body until you are both so horny you figure you might as well just fuck! She moans so loud but hopefully your parents dont hear!
