Through The Keyhole

You have been hanging out with Georgie's brother but when he goes out to fetch more beer you decide to head down the corridor to spy on Georgie. She is in her bedroom and you can see her through the keyhole in her door, she is wearing a very short skirt and it doesn't take you long to see a flash of her panties. You get an instant hard on and wonder if you can get away with having a wank outside of her door!
