Dr. David, a rugged, bearded man with a penchant for the forbidden, finds himself alone with a patient, a young twink with a raging hard-on. The boy, oblivious to the doctor's gay desires, innocently spreads his legs, allowing David a clear view of his throbbing cock. David, his medical training kicking in, decides to use the situation to its fullest. He picks up a bottle of lubricant, claiming it's for a 'routine check-up,' and begins to stroke the boy's cock, feeling it pulse in his hand. The boy moans softly, his eyes fluttering closed, as David's expert touch brings him closer to the edge.
