"Come on, I really need to use the bathroom"

I try to keep steady pace, but I'm put off by the loud banging at the door. It's difficult to get off when someone is right outside trying to break in on you! Goddamnit, though, who the hell needed to use the bathroom that bad?

Then I heard the voice of a young boy yell out: "Come on, I really need to use the bathroom, whoever is in there!" That did it, my dick shriveled in my hand. There was no use in trying to jerk off anymore. The only reason I came in here was to get rid of my erection, and I did.

So I said: "Be out in a second." I tucked myself back into my pants safely, washed my hands, and exited the bathroom as the little boy outside rushed in and slammed the door behind me.
