A nice round ball should be able to be pushed out by your ass and stomach muscles. Both times I ended up in hospital the dildo had a flat base and I couldn't push it out. I'm sure one of the fisting friends would have gotten them out. Like you I got carried away and very excited and wanted more and more in my hole. Last time a couple of young female doctors tried to reach in and pull it out but it was too slippery, so under anaesthetic and into surgery but no need to cut me open. So now I always leave part of the dildo or plug out of my hole when I'm using it.
Yeah I know but I got carried away as always my hole was nice and loose and it was fucking nice after the panic died down a bit also a fucking turn on thinking I would have to go to hospital and a doctor would fist me to get it out again
