However I will say that the largest breasts I ever saw in person, non-professional, were on a Japanese woman, a friend of a friend. I've only met her twice but each time was a pleasure!
She is about 35, very short, and a bit overweight. Each breast is much, much bigger than her head. She stoops a bit because of their weight, and I honestly don't see how she manages to do anything around the house, let alone walk. If you can imagine breasts bigger than Subgirlie's (though not quite as round and bouyant) on a small Japanese frame, with an unfortunately dumpy ass, you'd have a good picture of her. She currently has a seven year old daughter - very cute, very thin. When that girl hits puberty... some lucky boy is going to lose an eye!
