You're in for your medical exam today and we are going to be checking your genitals to make sure they are functioning well. We will be doing this via urethral sounding. I'll bring my two lovely Assistants in, Cate McQueen and Miss Audrey Brynn and yes, I know they can be a bit rude and abrupt sometimes but they are very helpful. We will start nice and small for you, with plenty of lube, and gradually will increase the size...
