RKT1001: I have enjoyed breasts of all shapes & sizes over the years, from the magnificently sculpted and firm B-cups up through the somewhat floppy but always fun natural EE-cups [and larger].
I guess if I had to pick my favorite, it would be a slim, toned girl [but not a stick figure, anorexic or emaciated type] whose breasts are just a "bit" too proportionally large for her figure, but not excessive. e.g., the aerobics instructor with DD's, or the petite cheerleader with full D cups.
Fond memories.
