<human>: Have your boobs ever expanded with milk to monstrous sizes like mine GF can? Every morning i wake up and feel her breasts getting bigger and bigger and even filling with milk (a literal breast expansion). Then once they get too big, it starts to tickle her a LOT and then she has a letdown!

Sometimes i suck them so that they don't burst or something, but this feels really good for her yet i'm not sure how big boobs can even get. Apparently they can grow to ridiculous sizes, but my GF wanted to know if this has happened to any of you? She doesn't feel pain when this happens, just a ton of tickling and even sloshing.

Can you provide a brief overview of the text?
<bot>: Even when they get enormous, they're still soft (almost like water balloons, but not really). I'll update this question more when her boobs start up again for more info.
