I think multiplayer in NSFW games is a cool idea, but unfortunately very hard to implement not just programmatically, but also ethically, given that multiplayer even fits with the type of game in the first place.
I really hope this works out for you and you figure it out, because it sounds really fucking cool!
Multiplayer is in the game right now, so you can try it out. I made many considerations when designing the systems to ensure maximum safety and privacy in online interactions, mostly through limiting direct interactions. The only direct communication possible is through the names of characters and servants, so any abuse should be quite limited.
