Ana is the taller, bigger, thicker, and infinitely more conservative sister. She always looks uncomfortable showing off her frame and usually is goaded by her sister. Lexie is slimmer, sleazier (convinced the LA Boutine shoots they did showing off their body and ass was mostly Lexie's idea), and has her tits done.
Without Ana Lexie would for sure take it at least to daily teasing levels. It's a shame. They are some of the most top tier women I've ever seen. Great face card. Ridiculous ass. And they're literally twins to boot. I was big on them when they were college students but they fading fast. Gotta pick a lane, ladies. Or let Lexie go on her own and live up to her full potential.
