>>87421964Because a girl with a completely flat ass is a waste of time. She has like no reason to exist, she's worthless. Nobody cares if the girl's boobs are small, that's some shit only a child would complain about. Now if she has a tiny, non-existent Hank Hill ass, that's a fucking tragedy there.
People with taste (not the Japanese) like ass. We like shapely, firm and fat butts.
A girl with big tits is nice, but it isn't necessary. A nice ass, SOME ass, is.
