The face, especially if she has a really nice pair of soft cheeks on her and eyes that droop ever so slightly on the outer sides... Mmm, MMM. Me likey.
If that doesn't count, then I'll say the thighs, you know when a girl has both of her legs pulled up when lying on her back, or has just one leg pulled up when she's standing and kneeling over, and you get that really distinctive shape right where her butt is, that's like... I'm not even sure how to describe it, anyone else that knows what I mean will know the shape that I'm talking about. That shape just drives me wild, and that shape wouldn't be possible without those wonderful wide-set thighs.
Praise the lord for the female body! Praise him! Praise him!
