Strange question for a porn board, but... :dunno:
It does. I only went up one cup size and a band size (34B to 36C), and when I stopped breastfeeding I went back down to my "normal" size, so the new size isn't a permanent thing. I have heard of women who have remained at the breast size they grew to while nursing, but I wasn't that lucky.
I don't think that's really an accurate line of thought. A woman can try to increase her milk supply, but it doesn't mean she's going to increase her breast size by doing it.
:hatsoff:
