The doctor's gloved hands trace the twink's smooth chest, pausing at his nipples, making them harden. The twink squirms, "That's not part of the exam!" The doctor chuckles, "Relax, I'm just making sure you're fully healthy." His hands move lower, cupping the twink's ass, then moving to his crotch. The twink gasps, his cock twitching at the unexpected contact. The doctor grins, "Looks like you're enjoying this, stud." The twink blushes, but his body betrays him, his cock hardening at the gay stud's touch.
