Breasts are like strippers. They're plenty hot on their own but they're even hotter when they're moving. Watching breasts heave, rock, swing, and sway can be just as enjoyable as actually handling them. If anything though, I bet women wish they had the +/- breast function. They could shrink 'em down to mosquito bites when the creepy guy is around or they're jogging and then super plus size them when they're looking for attention.
