I've only had one hard one and do not intend to repeat. I was breaking a pause of 5 days, waiting for the toy to arrive.
I managed to get a brand new vibrating and sparkling but plug in, that was too thick. Took on a quart of warm baking soda solution, J-lube, and greased it with my favorite hair conditioner (Botanique Expert). Then after running the "Beating Mango" through all its mighty strange paces, 8 vibes and 8 shock rhythms, i felt i wanted to test its butt plug qualities more. Slid the 9/16 colon tube in beside its 3/4 inch neck and released the spray. I have my reservoir set up so my toes can let more warm or cool filtered water fill it while it is filling me. The two in there side by side made a 1-3/8" figure 8 anal stem. That did not seal perfectly, but with the bag hung high, it was filling my wishes nicely with a little trickling leak to appreciate as well. I took on 8.5 pounds of water and desperately squeezed it off.
My interest is in having a unique (strange) enema ride and a sexual climax causes me to forget. So i usually avoid that. Was able to get 15 inches of that tube to poke up to some where just below my ribs on the left side (naturally). Then with that monster buzzing and throbbing, i could easily use my finger tips and trace the tube from where it emerges out from the pubic bone and arcs over to the left side. Then following it on up to where its tip was going crazy in there. With the leak trickling out the entire time, the fill was slow and allowed more time for me to play with it. That was a quart more than i have ever entertained and was honestly even afraid of going further. There was a little pain blowing and tugging the plug out. The splash was loud and violent when it popped loose.
I have not told it all, yet you can understand how this left me with a soar butt for at least two days.
The toy is waterproof under mild conditions. The controller is splash proof. The directions insinuate that most people are known to quickly toss it out, and so, be aware of throwing it where its battery might pollute. I might mail it to my high school girl friend, for a hoot and with the same warning.
Including showering off afterward, the whole trip lasted 2.5 hours of live enema action, not including set up nor my room clean up.
