For me, I prefer a 36C+, my currect girlfriend is a 38C(Though she should be in D, she just likes her bras pretty tight because she is a cross-country runner & in the Navy), and I require a pretty big ass without over-doing it. Bubble butts > White girl butts
I'm not really massly shallow, I just thought this may be a fun topic of discussion.

And girls, replace breast size with penis size.

Maybe tonight we'll fly so far away... We'll be lost before the dawn...
