"Milk Your Cock"

You've gone round to your girlfriend's place, but she's not in right now. Her flatmate is home and you've always had a bit of a thing for her. As you're standing chatting to her, you're able to see her nipple poking out of her blouse and you can't stop staring. It doesn't go unnoticed and Amber calls you out on your pervy antics! Lucky for you though, Amber is a naughty minx and wouldn't mind if you milked your cock for her while she teases you...
