Naive college twink Tim hesitantly enters Dr. Harden's office for a routine check-up, unaware of the explicit examination awaiting him. The doctor, a rugged, muscular gay stud, smirks as he orders Tim to strip. Tim's slender, smooth body trembles with nerves, his cock twitching as it's revealed. Dr. Harden, his own massive firm stirring in his scrubs, lubes up and gently pushes a finger inside Tim's virgin ass, exploring the tight, untouched hole. Tim gasps, his inexperience evident as the doctor's finger probes deeper.
