No, you don't get it. Maybe I explain like shit, but whatever.
It don't stretch the skin, but what's inside is under negative pressure (pulled from every direction), so for some reason I don't really understand since I'm not a biologist-of-doom™ it make more boob-flesh to fill the gap.
It's like how buff guys gain muscles, they do it so hard it make tears in mooscles and when it heal it just add mater.
My explanation is messy, just search online if you want something better.
