In a makeshift college clinic, a lineup of twink swimmers awaits their annual medical exam. A handsome, authoritative doctor enters, his eyes scanning the room, landing on the erections tenting the young men's shorts. He smirks, "Looks like we have some eager participants today." Starting with a lanky blond, the doc lubes up and inserts a needle, the twink's cock twitching. As the blond's dick hardens, the doc exposes it, stroking it gently. The room fills with the scent of sweat and precum as the doctor works his way down the line, each twink's cock growing harder, ready for the next injection.
