Probably reverse childbirth of the butt. I'm just guessing.
bungman11's answer is spot on. And no, if done carefully, it doesn't lead to needing a diaper. It certainly hasn't in my case and I've taken toys much larger than a fist.
There is maximum stimulation of everything. It is unique stimulation. You have to learn to relax<br />
The sphincters are stretched. After you get through the sphincters, the intestine is small and re-<br />
quires stretching. There are little attachments that are eliminated when you massage the intestine.<br />
The prostrate has huge pressure on it. It takes time and practice. After you get<br />
anatomy accustomed to massage, it has. no equal. There are little ******* that occur all the time<br />
during *******, and working up to it. I have little o's all along, then one big. The prostate wi be empty<br />
and still contract with ******. Anus, inner lining,sphincters,prostate,bladder,intestine are massaged.<br />
When it is done right, you are not doing it to the anus. The anus sucks your hand in. If it doesn't want to, <br />
it won't invite the hand. There are moments when suddenly your hand is pulled in deeper. The whole experience is very different.
Here, I'll do it for you. I'll put a boot in your ***.
its gona hurt like a ***** id guess! you may need a diaper after.
