I have not had an entire horse in my large vagina but have had a good horse cock, several times.

I watched a farm housewife blowing, then fucking a horse cock until it came all over her. It was actually traumatic since I was quite young and not supposed to be there at the time. She was on a cart under the horse and two farm hands moved the cart back and forth while the massive cock moved in and out of her.
