Dolly "Hard Gym Cock"

Dolly is doing some warm up stretches in the locker room before you work out together, while you are waiting for her you notice that she hasn't worn a sports bra today and her gym top is pretty see through! When she bends down to stretch her nipples fall out of her top and your dick gets instantly hard, when Dolly looks up to see the boner in your trousers she tells you to pull it our and have a wank over her right in the middle of the locker room.
