@Chameloshi: I'd say do it, cause Zootopia has already become a porn giant, so much so that it's already passed FNAF, undertale, and digimon in smut count. https://e621.net/tag?name=&type=3&order=count

The only things bigger are sonic, pokemon and MLP.

@zenitix: Well, at least I'd be drawing something that technically doesn't exist yet. There's only three pictures of Judy on e6 tagged with "lactation", and none with "breast_milking", so I'd be contributing with something one-of-a-kind.
