Your doctor has called you back for a follow up to your last ED check up. She's decided to up your dosage from wearing heels to wearing her stinky converse. She wants to see if the extra smelly feet she gets from her sneakers makes you cum any more than when she wore heels. You lean back as she peels off her sneakers and she stinks her stinky soles in your face. You inhale them and instantly feel your dick get hard as she rubs over your boxers with her other foot. She edges you over and over with her slow sole movements up your shaft telling you she is pleased with her research this far. She wonders if you have told your wife yet. Finally you cannot hold it anymore and unleash a beast of a cumshot all over the place startling your doctor. But she is pleased to see the follow up is bigger than the first.
