Hey bro! I've been thinking for a long time about this and... well... ugh I'll just come out and say it. We're getting older, I'm almost to my thirties, and I still haven't found the perfect guy. I always end up with jerks or guys who just want to have sex with me. Plus, I'm always comparing them to my amazing brother, you've set the bar high. I mean, you're handsome, smart, kind, respectful, everything a girl could dream of! Yet all of those girls you've been with have taken you for granted. I have a proposal. Obviously you and I can't date, I'm your sister! But I was thinking... I know you've always wanted to fuck me and I've been DYING to get the chance with you so.... this ONE time will you fuck me and... cum inside of me and get me pregnant? We would make the most amazing, beautiful ba bies and I just don't want to wait anymore. I see you're hard already, let's just do it, please brother, slide your hard cock inside of me and release your seed
