A lanky twink, eager to become a doctor himself, enters the clinic for a practical exam. His instructor, a rugged, hairy gay man, begins the physical, running his hands over the young man's firm chest and toned arms. The twink's nipples harden under the doctor's touch, his cock twitching in his pants. The instructor, noticing the bulge, smirks and moves lower, feeling the twink's abs, his fingers brushing against the growing erection. The twink, trying to hide his excitement, gasps as the doctor unzips his pants, revealing his hardening cock. The instructor, now fully erect himself, leans in for a taste, his tongue circling the twink's sensitive tip.
