anal sphincter

Some would say quite similar to the asshole, the anal sphincter is like a little drawstring that loosens and tightens up your asshole when things are coming in and out of it.

My grandma has shit constantly flowing out of her asshole, she must have a problem with her anal sphincter.

Sphynx

full waxing of the vajayjay, completely bare, hairless, all of the hair on the pubic bone, lips, under undercarriage, including asshole hair, similar to a Brazilian Wax however there is no hair left, not even a landing strip

I need to call my esthetician and schedule a Sphynx, she's the best and she never leaves a single hair. I love my Sphynx, it so soft and clean, especially my undercarriage! When I get my Sphnyx wax, it doesn't even hurt when she waxes my ass hairs!

"Did you see that TV show with the juggler who was performing for the Queen? Wow, I sure did have a sphincter-blink when he dropped all those balls!"
