I love thick legs on a girl. Very sexy! Accompanied by a callipygous butt and it's even more sexy. Butt I wonder if this is a southern California thing, as many girls in the Santa Monica/Venice beach area have full legs due to all the beach running, biking and roller blading. It's how things are here.
As for the links ... Brooke's thickness is okay with me, it's just that her manly definitions appear to be showing and I don't care for that too much. I'd date her if she asked me to, but I wouldn't approach her unless she was giving me the "come talk to me" smile.
I like them; dated athletes when I was younger--was one myself--so I'm used to legs like that. The chicken bones of current fashion, those freak me out.
How to get them: See that word "athlete" up there? You'll need to be active; it's not an accident that one of your pictures is from a road race. Run, lift, bike, swim. Do something that works for you, and stick with it.
