During a routine prostate exam, doctor Tina is shocked to see how tiny her patient's penis is. His prostate is fine but the real problem is round the front! She starts humiliating him for his lack of size and when he says he's a grower she challenges him to prove it. The sad loser has to jerk off in front of the hot doctor as she laughs and makes small penis gestures with her hands. Eventually she slaps his hand out the way and takes over herself, wanking his cock until he spurts out a pathetic cum load
