The clinic's sterile scent fills the air as Old Guy, the sole practitioner, awaits his next patient. A young twink enters, his eyes darting nervously, unaware of the doctor's proclivities. Old Guy begins the exam, his experienced hands exploring the twink's body, his touch becoming more intense. He guides the twink's hand to his throbbing cock, hidden beneath his scrubs. The twink hesitates, then tentatively touches the doctor, feeling the hard length through the fabric. Old Guy's breath hitches, his desire evident, as the twink's fingers trace the outline of his cock, exploring the taboo temptation.
