I'm afraid we don't have options like that. It would cost extra for us to redo the art and it'd interfere a bit with the writing as well, which points out some of these aspects.
Our other game, Benefitship, also has a little bit of it, and while Born to Breed (yet another game by us) doesn't have cumflation, it does have a scene with a fairy, which includes some belly bulging.
I wouldn't say it's super extreme in any of these games - it usually just makes the characters look late-term pregnant or thereabouts. The belly bulges (such as the one in the fairy scene of Born to Breed, which you can see on its store page) are quite blatant, though.
