Several nearly flawless butts:
Keyra is always amazing:

but not perfect for me. It has to do with the "oval-tilting toward one another" shape. I prefer rounder, and perhaps ever so slightly fuller
This is the perfect "pop" but lacks in texture and slightly in shape:

Some asses, even though they aren't perfect by themselves, become incredible when placed with a beautiful girl:

these three show an interesting array, and the girl on the far right is flawless(lexi belle):

+Rep for the excellent pictures with appreciated opinions. Keyra.. just who is she? I've only seen her ass over the years and nothing else. She looks white but.. us whites arent much known for being 'assy'.
