A large amount of enema is injected into the anus! While the patient is trying to hold back from squirting, the master pistons her throat with a deep throat blowjob! If she can make him cum without leaking a single drop of the enema liquid, she'll be rewarded. If she squirts an enema, she'll become a cum urinal for dirty patients! - The proctology department of our hospital holds an event with new nurses once every three months. In order to reduce the daily stress around the anus, our nurses feel the same pain and share the pain with the patients. Enjoy enema injection and squirting endurance that goes beyond common sense.
