Surprised that
Her Heart's Desire isn't on the list with it being 'completed' quite a while ago. You are an actual real life landlord (!) but you can set the relationships (to you) of the girls you let into your home to pretty much whatever you want. The dialogue is a bit iffy when it comes to certain relationships but at least it's possible without mods, etc.
The backstory does not adapt to the incest relations, and the math doesn't work. Long lost Daughter/tennant shows up. Age of the MC is set at 36 I think? All fine and good, so he got her momma preggers at 18. Then two other girls show up. They all look dramatically different, but are from the same Momma, and are younger than the first girl, so he was making them when he was in High School, but somehow didn't know he knocked up their Mum 3 times? Even by porn logic standards, it's obvious the incest was tacked on, and not really thought out at all.
I still enjoy the lewd scenes, the sound effects are over the top hilarious, and every lady in this world squirts like a fountain. Just would have been a lot more enjoyable if some planning was put into the Daddy/Daughter option. It just comes off like very strange roleplay.
