I think that you would be doing extremly well if you gained any permanent growth in six months. How do you tell if you have permanent growth? Well i guess you have to stop to find out. I think that is pretty unadvisable at the begining of your noogle journey.
Yes I think Anatasia did stop for six months after pumping for a year and kept her size.
There is a user on here you may have heard of her, Phili? She pumped for 3 years I think, went from a B to an E and now pumps just 15 minutes a day to keep the perkiness, that probably shows that her growth is permanent.
I am 100% sure that I am not goimg to spend the rest of my life with these plastic domes on my chest for 2 hours a day - NO WAY but I can't really imagine stopping pumping, I mean 15 minutes a day? That's not goimg to kill me, and for an E cup? I have no problem with that!
