The clinic's dim lights cast long shadows as the doctor, his white coat crisp and pristine, leads the inexperienced twink to the examination table. He instructs the young man to undress, his voice firm yet gentle, like a teacher guiding a pupil. The twink blushes, his hands trembling as he bares his lithe body, his cock already half-hard with anticipation. The doctor smiles reassuringly, his experienced eyes taking in the twink's lean form, ready to guide him through his first steps into the world of gay sex.
