That would be a great question to my ex who had a GG Cup size!
Sometimes things need support too!
One morning, she had stayed over, she couldn't find her bra (as if it wasn't big enough!).
I said to her "Have you lost your "Stables"?
She looked at me with a quizzical expression and said "what on earth are you going on about"?
I said, "you know your Stables, it's where you keep your GG's (Gee Gees is another term for horses).
She was not amused and threw something in my general direction, I chuckled about it all day, once a funny thought about boobs is in your head, well it hard to forget!
10 mins later "chuckle", to be honest, it wasn't the joke that was funny all day, it was her expression on her face.
She laughed about it later though!
I am all in favor of equality, ladies if you don't need a bra to support your breasts, show those nips!
