To me it really depends on the individuals preference as well as the woman who's been augmented. Micah Moore had an amazing petite body before her implants, but she turns me on just as much with them as she did without them, same with Lupe Fuentes (aka Little Lupe). But both of those girls had slight frames and small breasts fit them really well. Girls like Bridgette B and Memphis Monroe, with somewhat more substantial frames, I think look better with implants. Plus the fact that both girls' implants were done without looking like hard plastic bolt-ons helps their individual situations. Angelina Valentine looked better with her first set of implants than she did natural (in my opinion that is) but the latest incarnation of breasts that found their way onto her chest were horribly done and took away a lot. Lela Star was another that looked amazing with her natural breasts, then she lost her ever-loving mind and underwent a number of plastic surgery procedures and lost that amazing natural look that she possessed. Cody Lane's implants were a complete nightmare. First she was amazing before hand, then she got her breasts augmented and the doctor did an incredibly shitty job and screwed up her breasts something terrible. Last I heard she was raising money to have them fixed and restored to their natural beauty.
I rarely advocate for breast augmentation at all, but I won't say that I'm flat-out against them. In my view, while some augmentations are very unnecessary, some women genuinely do enhance their physical appearance with them while others are faced with deep regrets after the fact. No matter what though, the girls I've named I find to be attractive and won't stop being a fan of theirs just because of their choices. I do hope that the choice to undergo such procedures are done with more thought than just "career" advancement, and no matter what I wish them all the success that life has to offer.
