Prior to about 1995 there was a dungeon in Manhattan called Belle Du Jour. I went there any time I was in New York. The studio burned, and it was believed to be arson by some do gooder. It never reopened.
I would stay in a hotel near Central Park, sometimes the Hilton and sometimes the Parker Meridien, Belle Du Jour's studio was in lower Manhattan, a good healthy walk.
My usual session I would get an enema and then give one to the girl who just gave me one, it filled an hour nicely. Actually, the girl usually went first because filling and playing with her as she expelled was my turn on, my enema and the happy ending were a nice finish.
As we all know sometimes an enema decides it's just not going to come out, sometimes you think you expelled most of it, but you hadn't. And this was the case that day, and while I was pretty sure when I left there I was done there was as much as a quart of water left inside. I probably was about a block from the studio when the urge hit, and it was strong. It was also an erotic challenge, knowing it would be very embarrassing if I couldn't hold it.
So I gave myself the challenge and with a lot of struggling I made it, on foot, though Times Square, and to the hotel, once in my room I quickly closed the door, sat down, and had a really wonderful expulsion. And I masturbated again it had felt so good!
