Oh, you accidentally chose anal, so you're gonna fuck me in the ass?

Quiet, sister! Or your parents will come and stop you from getting laid

Brother won't tell parents about his sister's outing, but only for a blowjob

This is blackmail! You can't fuck a guy, but you can fuck your brother for keeping quiet?

Hey, I'm your brother, I don't have to suck up for the ride at all

Since my brother saw everything, let him blow off steam and his sperm with it

He jerked off to his panty-less sister and got aroused - oh, shit, he got caught
