You have gone to the doctors to ask for some Viagra but luckily for you Dr Sapphire has something that she thinks will work even better, she asks you if she can examine your cock and slips her hand under your towel. As she leans over her nipple pops out of her blouse and you get an instant boner, Sapphire begins to rub your dick under the towel increasing her speed until you blow your load all over her hand.
