In the sterile, cold room, the doctor's latex-gloved hands roam the twink's body, sending shivers of anticipation through him. The twink's cock, already hard, tents the paper sheet, drawing the doctor's gaze. With a wicked grin, the doctor leans in, his warm breath on the twink's ear, 'Let's check that gag reflex, shall we?' The twink nods, eager, as the doctor's cock, rigid and pulsing, is brought to his lips. The twink opens wide, taking the doctor's length, gagging softly as it hits the back of his throat, a test of endurance and desire in this taboo, exhilarating encounter.
