I'm so sick of you always being a dick to me step-brother, I think it's time I got some revenge. What do you think mum and dad would say if I told them about you smoking pot every night? I bet they wouldn't be too happy now would they? I'm not kidding so don't test me. Although there is one thing you could do that might keep me quiet...I want you to get me pregnant. I'm serious brother, I want you to fuck me and leave a huge load of cum inside my fertile pussy. Don't you think it would be kinda hot, blowing a huge load inside your little sister's unprotected pussy? It's up to you, but it's the only way to keep me quiet ;)
