In the dimly lit, sterile room, the twink's heart races as the doctor's massive, calloused hands explore his body, awakening desires he's long suppressed. The doctor's fingers, slick with lube, probe the twink's virgin ass, stretching it, preparing it for the doctor's thick, engorged cock. The twink gasps, his own cock leaking pre-cum, as the doctor mounts him, his massive body casting a shadow over the twink's slight frame. The doctor grips the twink's hips, his fingers digging into the soft flesh as he begins to thrust, claiming the twink's tight, virgin hole as his own, in a raw, passionate display of gay medical exploration.
