Generally what's the largest the character's breasts become?
well, the hope is that it never stops, even though the story is sadly close to reaching its end, but maybe it'll never stop, as it should.
For the normal ending maybe “bigger than torso/down to knees” size and for the epilogues up to immobility and more (bigger than body/room filling) if players want that. 😉
yes please! lol
