It would seem that Eddie is quite a fan of what is known as a bubble butt, and while i do love a nice round fat ass, there are plenty of other nice asses.
I like a nice tight and firm ass, I would say Sky and krystal have those types of asses.
What I like about Nikki's ass is while it may not exactly be round or curvy, I like the tightness, the kind you could bounce a quarter off. It looks firm but not to where its not flat either. I think its the type of thongs she is wearing, sometimes she wears them too low, I think a thong should be worn high so it shows the whole ass, I hate when a thong covers the tops part of the ass.
But I think we would all agree thats it not her ass that attracts us to Nikki, its her big huge natural DD tits, and her innocence.
