A nervous twink arrives at the doctor's office, his anxiety palpable. The experienced gay doctor, a mature stud, notices the young man's discomfort and decides to make the examination more... engaging. He starts with a casual, professional check-up, but his hands linger, his touch becoming suggestive. The twink's body responds, his cock twitching in his briefs. The doctor, feeling the growing bulge, smirks and begins to stroke the young man's cock through his pants. The twink moans softly, his eyes closed, enjoying the forbidden pleasure. The doctor, now rock hard himself, unzips his pants, revealing his thick, veiny cock. He strokes it slowly, watching the twink's face, and with a groan, cums all over the young man's stomach, marking him as his.
