UpSkirt Jerk - Demi - White Lie

Your girlfriends' sister is dressed in her cheerleader outfit and is on all fours trying to look for her trainers. You can see right up her skirt and it's making your cock rock hard. Demi tells you she's going to have to borrow her sisters' trainers and asks you not to tell her. But you tease her and say you're going to tell your girlfriend. But Demi can see you're having a good look up her skirt, so if she was to show you more and let you wank your hard cock, then you won't tell her!
