This story is 100% real so it may not be as exciting as a fictional tale.
When I was in college there was a girl I had a huge crush on. A lot of people would compare her looks to a young Linda Hamilton and there's nothing wrong with that. Hamilton wasn't a stunning beauty but but she had a sexiness that other more classically attractive women often lacked. Besides some smoldering good looks she also had some awesomely big boobs. She was one of six sisters and was the only one blessed in this area. Her uniquely large breasts and looks that seemed to differ significantly from her sisters led to quite a few jokes about her mom and the mailman.
My friend had always struggled with the battle of the bulge but during that period she was winning the fight. I never actually got a chance to touch her breasts but I imagine they were extremely soft despite her young age. Fast forward twenty years and the battle with weight had become a complete rout. She blew up like a balloon and her youthful attractiveness was gone. She went from being a decently thin girl with big boobs to a fat girl with big boobs. Her body had caught up with her boobs and now everything was in proportion, in a bad way. She did recently confess to me her bra size and it's quite large, well beyond DD, but nothing I would have interest in touching. In her youth she probably had no interest in me but today I am out of her league. I have actually maintained my health and weight.
Please don't take my bluntness for bitterness. I wish her nothing but the best and actually feel sorry that life has taken her down this path. She has never married or had kids and any sexiness she had has evaporated. I have no idea whether her breasts, even at their peak, were any good. Taking a bra off is like opening a present, you never know what you're going to get. In one instance I got into the bra of a co-worker who I thought had some full breasts only to discover she was, at best, a B-cup. Somehow, the shape of her body gave the impression of much larger breasts than reality. In another case I was with a classmate who had D-cups. They were big but she was quite large and her breasts were fairly flat against her body. She was just a big girl with a decent amount of breast volume but proportionally they were entirely unimpressive. In one instance the girl had small breasts, as expected, but what really surprised me was the tiny size of her areolas, which were smaller than dimes. It lent a certain manishness to her breasts that I found unappealing. In all other ways she was very feminine. One of the nicest set of breasts were on a friend who was a small A-cup. I had no expectations and although they were nearly entirely flat they were appropriate for her body.
