I'd like to turn my own hole into a hole like the one in the video. The bottom's hole wraps around the dick and goes out with the dick on the way out. Also it seems that the bottom have control over this and can push out his hole as he wants for the top. Those two things and the way it looks are really attractive for me and I'd to have something like this as well.

I assume it's a small prolapse or no? And most important - how to achieve this? Any guides or tips would be very appreciated. Maybe your hole is just like this and you know how to make it happen?

Get fucked by big cock a lot, big dildos end very large anal plugs. Also, I do double anal with dildos weekly. I even have one that simulate it
