Oh my god, Bro!!! Didn't Mum tell you that I was getting changed in here??? Ewwww!!!! Ok, maybe just sit in the corner over there but don't look!! I'm trying on lingerie for my wedding night tonight. I'm soon excited!!! It's fine, you've seen me at the beach before. What do you think to this one? Wait.... ewwwwwww!!!! Have you got A HARD ON??? I'm your sister!!! Stop looking at me like that, I'm your sister!! Well, I guess it must be a compliment, this lingerie must look really good on me! You can't walk around like that though, Mum is right outside, you can't leave my room with a huge hard on. I know this is weird, but what the hell, this is my wedding day.... why don't I help you to get rid of it? I begin with some jerk off instructions, but soon I'm turned on too and I ask if I can get my lips around your cock. Ooh Brother, what a nice cock you have!! Soo, obviously you can't fuck me because I'm your sister, but maybe if you put it in my butt, that doesn't count?? You slide your cock in my arse and it feels soooo good, how could this possibly be wrong? I want you in my pussy now too, I want to stare into my Brothers eyes as you fuck me. Will you still walk me down the aisle later though Brother?
