Extrem pervert clinic anal examination by two nurses

Nasty Cora is about to take her intermediate exam as a nurse. Under the supervision of the experienced ward nurse, she has to show once again what she has learned. The experienced stepsister Sandra gives her a few tips on the way and shows her exactly how to handle such a man's asshole. First position the ass for good access on the gynchair and then spread with the speculum. With the help of an endoscope, one can then wonderfully see on the monitor in the intestine of the patient. It becomes clear: The rosette is much too narrow and has to be stretched many times over. A suitable means to first relax the sphincter, is the vacuum pump, in which the asshole is sucked and the sphincter is stretched by in its natural movement.
