I just finished watching "Amazing Ty #38: Cummin' Out My Ass" and may have witnessed the end of porn. Frankly, I don't know what other acts can be shown on camera. In this movie, Ty induces an anal prolapse 35 or 40 times, and it's a big one...three or four inches long.
Her partner in the movie, Extreme Missy, fucks the prolapse with her fingers, with dildos and, in one brain-damaging scene, milks it like a cow teat. As she's milking the prolapse, lube and all sorts of assorted ass juice concoctions come squiting out. Even when Missy is fucking Ty's prolapse with dildos, the prolapse stays outside her sphincter. I used to think prolapses were kinda cool. No longer.
Combined with how Ty fucks her pussy and peehole with huge toys, if she's not already wearing adult diapers, she will be soon.
