Too Much Noise

Your girlfriend is fast asleep, so you go down to the kitchen to grab yourself a drink, but you find her housemate bent over sorting through her laundry. You can't help but take a look up her very short skirt, but Ella can feel your eyes burning at the back of her. She knows you're being a perv, but if she quenches your naughty upskirt thirst and let you have a wank, will you then start behaving yourself!?
