Such A Perv

You're about to head out on the town with your girlfriend and her friend, but when you go into Ella's room to see if she's ready to go out, you find her bent over on her bed searching down the side of her bed for her charger. She catches you perving up her skirt and tells you although you've fucked before, you need to stop perving on her cause you're going out with her friend now and she's beginning to notice the way you look at her... but if you need one final wank, then quickly get it out of your system!
