Justin is visiting his doctor because he is permenantly erect. She doesn't believe him so he drops his trousers and out pops his rock hard cock. The pretty blonde doctor is confused as to why he is so hard when she is fully clothed and nothing sexual has happened. She tells him it might help if he empties his balls so she strips off to encourage him as he jerks off. She bends over and shows her peachy ass and then sits back down and spreads her legs. The sight of her exposed bald pussy makes him explode a massive cumshot high into the air!
