I'm not even sure how it got up there. The doctor at the hospital said something about reverse peristalsis, where a stimulated group of muscles will reverse its usual direction. That seems to be what happened there. I gave myself two cold-water 2 quart enemas before commencing playiong with my anal passage and my rubber dildo, and I was working away with it when all of a sudden my rear just sucked it up inside. I guess I wasn't hanging onto it tightly enough. I've only just started experimenting with anal play, and my knowledge in this area is regrettably spotty, and the package on the dildo didn'r say, 'Do not use in anus' or I wouldn't have used it 'back there'. Oh well. One more round to experience.
