There are Asian women with phat bootys naturally ... Like a friend of mine (more like acquaintance) that's Laotian. No enhancements. I've seen SOME Chinese women with them too... All natural. And this board is FILLED with white men who love phat bootys. There is a difference between phat and fat. Unfortunately, some don't know that difference between anything other than flat as a pancake is "fat".
There is nothing common or natural about this at all.
Maybe when they tell you it is all natural, have you considered they might be lying to you?
Like in, how many women do you know tell people
"oh my breasts, they are plastic surgery for sure, they are not natural. My natural breasts would never look this good."
-- Said no woman ever.
