I was watching Mike Adriano's Up Her Asshole. In the scene with Blake Rose (damn hot scene btw), there was a bunch of sex toy being shown in the beginning of the scene. One of them was a suction device that looked kinda like a penis pump, but in the middle of it, a long prong protruded out of the center of it. Looks like you insert the prong into the asshole and puch it in all the way until the pump cylinder is pushing up against the ass cheeks. The up start pumping and it forces a gape while the ass is being penetrated at the same time!
Unfortunately, it wasn't used in the scene (would have loved to see Blake Rose use it). I've seen some Evil Angel movies with a pump used on the asshole to make a forced gape, but with something actually penetrating the ass would be hot as hell to see.
Has anyone see it in action? Hopefully Mike Adriano can actually use it in upcoming movies.
