Patient M is a good patient, at The Dom House private clinic, we have alternative medicine solutions for every case. This time, slave m needed a very thorough check-up to examine and see why he is so horny all the time. Turns out he just needs his asshole opened up at max-width for his nurse's pleasure. The huge equine speculum is 17 inches deep and goes 4 inches wide, big enough to fit a baseball. Mistress Rogue plays the evil nurse role, delivering this extreme treatment for her patient's uncontrollable libido.
