little frustrating that despite katarina possibly being the most down-bad character in the game for you, possibly somehow rivaling anna, that she doesn't have easily repeatable content, and no anal or gangbang yet. lotta rich territory for including emma as well. but hey, she says she totally belongs to me. considering all the other stuff i do in the game i'd probably have her doing the most. you could even make her a money sink in late game, because she seemed to only be with mario for his cash. would give an easy way to develop her character some. she comes begging and acting all sweet for some cash, you tease and withhold it until she does some thing she pretends to hate, and then you shower her in cash after showering her with some other stuff, leaving her in a puddle of filthy money. maybe leash her at some point since you've decided to make her meow for you.
i have a similar dissonance with alice and adrian; you can do the most deranged stuff possible with him but alice remains off limits. hoping that gets ironed out in the next update!
i'd love to see content with amelia and other people in your household. she seems one of the more monogamy-coded characters, so it'd be great to break her in by exploiting her desperation.
hard seconding more isabella content though. not only distinctly lacking pregnancy content, but since she has a weird kink for the genetics of your household a lot could be done there. and such a waste of a great character design!
waiting patiently for 1.8. wanna drop some cash to support this when it comes out!
