This is the climax stage of the Standing Rough Missionary sequence.
The animation has a lot of speed changes and a variety of other constant pose changes. You can see a small preview of the 'main' action in the gif.
It also has maxed out sounds (If I try to add one more the animation crashes).
It is available for both versions with different sounds for each.
To get a good idea of it you mast see it in game. Looking forward to hearing what you think about it.
