Wow, talk about boob play, I should know, as the boobs got larger I really get off on it. They are so cool to caress and the nipples are delightful to fondle, also. Sexual, hmmm, maybe, but definitely feels soooo good. I seem to be one of the few who hasn't had a painful growing pains type of thing going on with them. I do remember early on how the nipples were like a bud, like a small tumor behind each one, which softened up with time. I was really concerned about it when it first happened. I am so very happy that I can fill my sport bra with no problem at all! It was wrinkly at first, but no wrinkles anymore. I still go braless at work and going out, but just knowing that I can fill it makes me feel very feminine.
