She was standing on his dick. I saw this video yesterday. It's an assault to the highest degree. She's a crazy, psycho bitch who can't appreciate being catcalled...mean's the dude found her attractive. Yet she goes pro-feminism and takes it to the next level. Fucking feminazi.
The shape and the thickness of the ass cheeks, combined with the waist and thighs like you said, is the thing that matters most to me when it comes to booty. The Hip:Waist:Ass ratio essentially. I will always appreciate a nice pair of boobs as any red blooded male would but generally speaking the booty is what I look at most (plus it's easier not to get caught peeking!) and gets the blood going. Bitches are too covered up there nowadays to get full view of their breasts anyway.
I mean look at like Remy Lacroix - doesn't have much of a chest on her but god damn does it doesn't even matter with that ass? Rarely have I come across a woman with big breasts and an ass to match. They exist but like Vasto Lordes... they're rare.
