I concur sir 
Since you have seemed to have seen it Last_Days_of_Logan with regard to the description as opposed to effect, (ie bounces) would you describe her
butt as biggish and/or round-ish??
Cheers!!
well its not big to start with.....so i would reluctantly say roundish from the side view.
hips to waist ration is about average...i.e nothing to write home about. That extra bit of roundness on the side of the arse cheeks, like ebony cherokee in porn, isnt there....
what i would say is that the curvature outwards from the base of her back to the furthest point to where the arse sticks out is alright...and it sticks out a bit to make a decent shape i guess.
the pictures are much better than the reality IMV
