Now that you mention "slim but fit (clearly works out) yet is still incredibly feminine....HOT!" women, I probably should mention
Mandy Bright. While I think her face is a bit "hit or miss" (depending on what her make-up is like), her bod is totally stunning. I just saw her in a recent vid called "Gym Brats" or something like that, and my god, my eyes almost fell outta my face! It was one of those vids where you're like, oh wow, this is a real privilege to see this!!!! ....and you feel like your cock is a kielbasa that's roasting over a fire for too long and is about to burst out of its casing/skin!!
Mandy Bright is definitely in the running....although I'd prolly still stick w/ Jennifer Max (as the face is still part of the body)...
