Here's a few ideas Id like to suggest to add to the harem atmosphere.
1. Add nipple fucking to the options for interacting. https://gelbooru.com/index.php?page=post&s=view&id=2369084
2. Review the interactions inside the empiral harem for ideas. "Magnificient Century" https://www.youtube.com/channel/UCXQWPE9GietMsPVvqL3KiEQ
3. Allow the members of the harem to wonder the old fort and lounge in a large room with fountain after they have been 'charmed'. Allow them to lounge and smoke with a hookah or use a cigarette holder while struting around.
4. Id like to see a belly dancing costume as an option, perhaps topless. Another ideas are black opera gloves like a French courtesan.
