In a dimly lit clinic, a portly twink timidly awaits his examination from a mature, silver-haired doctor. The grandpa doctor, with a stern yet gentle demeanor, begins his thorough check-up. He runs his gloved hands over the twink's smooth, hairless skin, examining every curve and contour. The young man squirms under the doctor's touch, his cock twitching as the older man's fingers graze over his inner thighs. The doctor, noticing the twink's growing arousal, smirks and continues his examination, his hands now sliding over the twink's firm ass and between his legs, causing the young man to gasp.
