Hourglass BBWs ...
THere's only one BBW in my opinion and that is Samantha 38g.
Unless Claudia Marie counts.
You're much like myself, you love the hourglass BBWs. I really don't go for the pear/spoon shapes at all. I like a chest with a matching set of hips, and then a significantly reduced mid-section. That means on a BBW she can still have fat popping out of the gut, but she better have bigger hips and breasts.
Love the two you mentioned, plus Maria Moore. Laura Orsolya is pushing it as of late as well, and may be considered a border-line BBW (from her more slender FFW) now. Another border-line BBW lust I've recently found is
"Ginger" ala "Ana" of Silicone Free / Divine Breasts.
I love thin hourglases too (I'll take 36-24-36 on 5'7", although it depends), but I also really love the wider, fuller women of 40+-30-40+. The taller and more "mamazon" ones like Laura are quite fine too. I just want that hourglass, or maybe a stocky, wide apple in the case of sub-5'3".
