Dr. Green, the renowned gay medic, welcomes two hesitant but eager straight twinks into his private clinic. After a quick, thorough examination, he decides to push their limits, introducing them to the world of gay pleasure. He orders them to lie on their backs, their bare bottoms exposed, legs spread wide. The doctor demonstrates, slapping one twink's ass, leaving a red handprint. The twinks, now understanding the game, begin to spank each other, their strokes growing harder, more confident. The room echoes with the sound of flesh hitting flesh, their moans and gasps filling the air as their cocks throb with newfound desire.
