Well, do they need to have actual gameplay? Because there are 2 visual novels from NTRMAN which fit what you are looking for. Adelaide Inn Remake and
The Queen who Adopted a Goblin. Adelaide Inn was removed from this site but I'm sure you can find it easily enough, it's a fantastic game if you are into what it proposes.
If you want a game with actual gameplay then I recommend you
Ema, Milf Warrior, it's a fun game with interesting interactions and tasteful enough art, it's a little bit grindy though so don't be shy about using the CheatEngine to bump up your XP and Money if you think it's taking too long to progress.
