I don't consider myself Bi-sexual, but I do enjoy being around other women. I love breasts too. So if I had to choose a woman whom I might be comfortable enough to 'play' around with, it would have to be someone like me. Not 'perfect' as in model type terms, and not even trying to be. They have to have confidence in themselves as they are
The bust size isn't really an issue as breasts are breasts, of course if I can cup it in my hand and still have a little nipple to play with, then I'd be happy. This is mostly just fantasy, as I don't go out looking for girls who might let me play with their boobs, but in the situation that it did happen she fit this 'mold' perfectly.
