Retention Enema?

My sub and I have been toying with the thought of using a large inflateable cathaterfor a retention enema. The tube is long enough to be inserted into the large intestine and then inflated, thus causing the liquid to enter the intestines only.

Anyone have any experience with this play?

Don't do it, the color will tollerate that, the intestines will not. An inflatable device needs to be just inside the anus, not deeply inserted.

Thanks for the advice and warning.
