My first post and I have discovered our favourite toy!
Me and the wife have been using a horse speculum for may years now, this can open the vaginal cavity to the extent you can insert your whole hand without touching the sides of her vagina. We, or rather me especially are into heavy fisting sessions, she understands the thrill I get from seeing her stretched open like this even though she is not that keen on the instrument herself but allows it's use due to the pleasure I get from seeing it in use.
We have used this for many years since she did get an erotic urge when being examined at the doctors, especially having a full internal exam. She has also undergone a couple of body cavity searches during visits to Africa and Asia, though we dont do drugs or that sort of thing, both of us have that look that makes us fell guilty about something even though we are not even smuggling a few to many cigarets etc and seem to get our bags looked at nearly every time.
Anyway thats getting away from this subject.
So a friend has a horse that is being treated by a vet and my Mrs spies this giant speculum being used, and how she would not like that up her. Well surprise surprise, I managed to obtain one of these from a veterinary suppliers and presented it to her during a fisting session.
I could see the look on her face, slightly worried but willing to please me so she agreed to use it. A bit of lube and it was up there as far as it would go, probably inside her by 8 or 9 inches. The thing was over a foot long and weighed about 2lb, not a tinny one but fully polished stainless steel, the 'blades were around 2ins wide to start with.
I opened it up till it started to give slight discomfort so stopped, then put my hand into her and probed her cervix. Normally she loves this but was more concerned about the speculum as the weight of it was causing her some discomfort than to have an orgasm.
After a little time we removed it and continued our fisting session, she is very large down there and has had several children which she says has relaxed her down there a bit and makes fist fucking a lot easier than a friend of hers who has had more children the she has.
Since then we have played with it lots, sometimes i have opened it till she can take it no more as the pain is too much when opened too far, but as she is into pain and humiliation and a bit of torture(real, not play, electric shock and the like) she does not mind every now and then.
