I'm wearing my black nursing dress with nothing underneath it. My breasts are so big now they threaten to fall out from behind the flimsy cotton at any moment. My bare ass, plugged, squirms against the seat of the car. We're going back to the place, the one with all the equipment you like to play with. On the way, you have me put my feet up on the dashboard and play with my pussy, keeping it at a low and steady hum, plenty wet. At red lights, you stop next to as many cars with single men in them as you can. Some of them flash you a thumbs up as they watch me work my hands under my dress.
We arrive, and the nice girl at the entrance checks us in, as usual. You inquire about using the exam room, and she says it's free for the next hour or two. We haven't been there before. As we walk through the space, the sounds of laughter and talking fill the air, along with occasional gasps, moans, the occasional crack of a hand on skin, a flogger, a muffled scream from behind a gag. You spot a friend of yours, who comes over with us. You speak to him softly for a minute, and he nods - "I'll meet you there" - and disappears.
The exam room has blue tiles on the walls and a bed with stirrups in the middle, just like the doctor's office. There is a light for close exams, and shelves and trays full of equipment. You slip me out of my dress and explain that it is time to do some tests. I am to be good. My breasts are full and starting to ache, as is my bladder. You help me up onto the table and raise and spread my legs high in the stirrups. Your friend from earlier walks in, now wearing a lab coat and carrying a clipboard. "Excellent!" he says as he comes in, sitting on a small wheeled stool and rolling up next to me. "Are you ready?"
"I'm not sure," I answer. "Ready for what?"
"Well," he says, "I hear you've been working on bladder control and induction and squirting, so you're here to measure up. We'll do a number of tests to make sure your body is performing as it should."
"Okay."
