Your file says you're booked in for a rectal exam, and the nurse snaps on a latex glove. "Just relax," she tells you, lubing up her fingers. She slides one into your tight asshole, and then two fingers. She can't quite get in deep enough with just her fingers, though. Fortunately, she's got an anal speculum on hand! She lubricates the metal contraption, then slides it in...and cranks it open! With your asshole spread wide open in front of her, the nurse is able to get in nice and deep and give you a full prostate exam!
