I would have to say and I'm sure many of our neighbors and friends would say the same, that my wife is self conscious about having smaller Breast / boobs / tits / or anything else you wanna call them!
I might have to take some of the responsibility for that cause all of my former girlfriends all have lots of Busty beauty and my wife knows all or most of them!
Besides that my wife's mom has that Busty feature along with our daughter, so it might have skipped a generation in the family?
Since we changed to the more Spicy lifestyle, my wife and I gets to see more of our neighborly wife's along with her cousin and my sister - all that are well Blessed on Top with everything!
My wife has been talking about having some Breast enhancement done and talked with others that had it done!
But in the back of her head she is always worried about having a bad job done or scars!
Going to a few Doctor places with her, I got to see plenty of pics of their Patients that had it done with the Before and After pics! Wow, I'm amazed these women are so willing to pose for Doctors with those boobs exposed!

But anytime there is something the women worry about, they'll make up for it and get your attention going to something else!
My wife did that when we first got together, she did oral on my cock then stopped to tell me I could CUM in her mouth and she'll swallow it! None of my busty GF's did that, but having my cock between those huge tits was always thrilling for me!
I'm sure more women have the same issue with their tits too!
