Bs are a good size, but so are Ds and Cs. It's all about the look of the boob. Must have good boob-to-nipple size...can't have huge nips and small boobs. As long as they look good, I don't care what the size is....but I'm a boob-man.
ill be honest and say that i have no experience with fake boobs, but i imagine that i would mid playing with them. but i wouldnt want a wife with huge fake tits
