I'm looking for a butt plug, with a tail (don't care what kind) that is spring loaded I.E there is a mechanism that will make it VERY hard to remove the butt plug. If someone knows of this please send me a link
I think what you're describing can be found here https://www.extremerestraints.com/butt-plugs_1/
Didn't sort through to see if any have tails, I know they do plugs with tails but not sure if the anchor ones do...
For anyone else interested in the more extreme toys these guys are really good!
