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

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

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

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

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

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

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