I'm with Jerry. Natural always beats fake, though with modern technology it can sometimes be hard to know. But my instincts in this matter are very refined, with many years of experience.
Funny because I love breasts that defies gravity, big or small I love them all. But in all honesty the best ones that I have seen was from a provider who used to have A's and got them increased to C's, they fit in my hands perfectly and her nipples got harder and longer from the surgery. She also wore shirts that showed them very well.
Fake boobs used to be a turn-off for me but, I have to admit that the results quality have improved significantly over the last 15 years. Now I can enjoy them more but, given the choice, I will favor naturals.
