I've got a rack myself (triple D, and anyone who would like to have some boobs made should see me first, I will donate cup sizes!) and they are homegrown. They sprang up FAST in highschool and people have been acting like the meaning of life was going to come out of them at any moment. I was in a large national chain electronics retailer years ago and the idiot helping me (a guy) kept directing all of his comments on the radio I was looking at to the "ladies out front". I finally leaned down until I caught his eye and said, "Excuse me there buddy, they don't have ears and aren't interested in what kind of radio I buy. Could you please talk to my face from now on?" I thought he was going to burst into flames....teehee.
Yes I have had people want to touch them, I was actually felt up by the great Lady Chablis at Club One in Savannah. She loved 'em! Weirdest experience of my life....
