Two lithe twinks, their tanned skin glistening with sunscreen, sneak away from the bustling nude beach to an abandoned lifeguard tower. The taller one, a confident blue-eyed blond, plays the part of the doctor, examining his companion's lean, muscular body with a fake stethoscope. He traces the imaginary heartbeat, lingering on the twink's hardening nipples, then moves south, cupping the boy's growing bulge. The blond twink moans, his cock throbbing against the doctor's hand. The scene heats up as clothes come off, and the doctor begins a thorough, arousing inspection of his patient's most intimate areas.
