I've found it to be near impossible to find a woman who will give me an enema just for fun, so I've resorted to occasionally paying for it.
I have used 2 professional enema services over the years. They were ok, but I've found it a lot more fun to use an escort service.
The escorts have generally been in their low 20's and have been "enema virgins". I never tell them over the phone what I have in mind. Once they arrive I describe what I want them to do. So far none of them have objected. One girl even allowed me to give her a bulb enema. I told her I need to show her how to do it before she gave one to me.
I know some of you have had similar experiences. How about sharing your true stories? No fiction please.
