Hey, one suggestion that I think is a good idea: slave's relationship.
You have two (or more) slaves have a relationship among them. Can add couple room. Necessary high obedience, loyalty and approval (or not).
Every day there is a chance for Essense drop, and maybe impregnation.
I had to unlock intimate relationship with males to create a hybrids of two rare species and "watch" them do the thing lol.
I've been meaning to suggest this, myself. The tutorial implies that slaves who have high lust could potentially get intimate with other slaves, however that doesn't seem to have been implemented yet. A "breeding room" or "couples room" could allow two slaves the chance of getting intimate, depending on their lust stats. Perhaps it's even possible for one slave to force another, keeping things more realistic.
I think only one of these rooms should be added to the game, and after being bought, it should be treated with just a bit more luxury than communal. Then maybe an upgrade to the room allows it be considered as good as a private room.
I'd like to have more than one, but not many. Two or three, with a higher building cost than private room.
Also, the slave forcing another one could be considered an event, triggered by high lust and low obedience by the offender. Then you have to do something about it, or else the forced slave would feel insecure or something.
No more than two, I think, since these count as sleeping rooms to house slaves. I wouldn't even mind seeing two communal bed slots removed for one of these double rooms.
What I'm thinking is, if one slave has high lust and sex-crazed/perverted and the other has low lust/lewdness/prude or anything else that causes sexual interactions to become more difficult, then the chances of rape are high but if both are say, perverted or fickle or have high lust, then they'd have a mutual enjoyment.
I don't know about you having to do something about it. I'd treat it as a stress event like sending a slave to Umbra as a fucktoy. They don't actually complain, just gain a ton of stress. Maybe some red text about them complaining to you/headgirl about it.
