Contrary to popular belief Bubble Butts are ~not~ big asses. Bubble Butts are round like a globe, usually complement a slender/slim body, they are very tight and firm unlike the one's on fat asses...

A big, fine perfect round ass. It is not huge and gross, just bigger and better than average size. Every girl should have one of these. These anatomical masterpieces can give many guys an erection.

A big, fine round ass. Most black girls and many white and latina girls are blessed with these anatomical masterpieces. They are as fun to watch and just as fun to grab.
