Lucas is ordered to bend over on all fours on top of the doctor’s desk to demonstrate how the patient is used in public urinals. The innocent boy is started to feel his arsehole being prodded by the pervy man. His sphincter is widened and he gets a strange tingling sensation as he feels his prostate being stimulated for the first time. The doctor strokes his tender penis at the same time to create an erotic association in the boy’s mind between sexual pleasure and getting fucked. He’s never going to be the same again after this treatment.
