Ur sis comes to you with quite unexpected request. She says, that she is going for a date with that hot guy tonight, and he turns her on so much, that she gets instantly wet. But she doesn’t want to have sex with him at the first date and to make him think, that she is a slut. So what if you will undress for her and help your sis to cool down a bit. Finally, her own brother can’t turn her on… or can?
