It is all too easy to say a girl has a great ass. Especially if you have seen a ton of flabby shapeless butts, the second you see an ass above a 6 you immediately rate it as a 9! You then come across the perfectly formed bottom of Natalie Sparks, which presents a problem.If you gave that above average ass a 9 what can you give this firm and juicy butt that is at least a 9? Looks like we are going into double digits and giving this girl a nice round 15
