Your Sister Blackmails You into Breeding

You say you are just interested in sex.. You lie to your friends about how you aren't a virgin. It's only a matter of time though before someone finds out your lie. Maybe we can make a deal.. I want to know what it's like to have sex too. Lets practice on each other and you can tell me if I'm giving a good blow job or not. Apparently I am good a bj's because you bust quickly in my mouth. What the fuck? We haven't even had sex yet! I tell you to leave my room and come back when you are actually ready to fuck. You come back with a hard dick. How are you hard so fast? You watched porn.. but, I know what porn you actually watch... You watch brother and sister porn... This is more than just wanting to lose your virginity.. you fantasize about me. Your sister.. Let me admit my secret fantasy to you bro.. I have a breeding kink and I know you are too weak to pull out. Your sister's pussy feels too good. You give me the most amazing warm rush of sperm inside me. You are weak and must breed your hot sister.
