A long time ago, I was with an escort in my Toronto hotel room. Things were going great - I was pumping her in mish and was close to the point of no return. I had been feeling a little off, but not enough to cancel the encounter. All of a sudden, I had an awful feeling in my intestines, and I realized I was about to have an attack of diarrhea. It was either cum and shit, or stop immediately and run to the can. I chose the latter, and made it just in time to explode in the toilet. The lady was grossed out, and I couldn't blame her. I was terribly embarrassed, but what could I do? She got ready to leave and took off in a hurry. I made no attempt to stop her. Fortunately, that was a one time occurrence.
I never used that agency again, just in case.
