Attlantic has posted this three panel breast expansion comic to deviantART. I’ve got a thumbnail of the first two panels at right – if you like women rendered helpless by gigantic breasts, you’ll need to check out the third panel because it’s pretty awesome! “I’ve fallen and I’ve got gigantic breasts!” should be the caption.

Attlantic doesn’t have a whole lot of expansion or growth related works on deviantART, but there are a handful. He does have a lot of big-breasted works,though, plus the occasional muscle girl or lactation-related work.
