I took these the other day in a Jerkle K (a rare visit - they happened to have cheap gas, and I was almost out of gas...).
Image 1, shows the delineations:
A = shoulder to waist
B = shoulder to waist to where the ass starts curving under
C = the actual functional part of the ass (decent here), which highlights how little ass most (particularly skinny) girls have. All the more to....you know.
Image 2 shows from the back the functional part of the ass.
Image 3 is an addendum, indicating what makes a pear shape.

Consider it high comedy....sincere tragedy....whatever...don't take it personally.
