As for me, I really LOOOOOOVE the mother pushing her youngest daughter into doing perverse things with her son!
Honnestly, I'm a little fed up with the stereotypical mother who tries to "be the best mom", avoid the incest as it is bad but nevertheless becomes a slut as the game ends up. I have always found this a bit unbelievable : if the mother is pure by nature, if she really wants her children to avoid having sex together, then I don't see how whe can accept at one point that her young teen daughter is being fucked like a slut and even, maybe, pregnant with her son's child.
There, in Apartment 69, we have something original and unseen before. It changes EVERYTHING in the common incest plot that we play with almost 100% of the other incest games, ansd it opens many possibilities.
Personally, I really hope that the mom will take this opportunity to satisfy her twisted desires, and work in the shadows to really raise and transform Eve into a real perverse slut. As the son is unaware of her mom comploting behind his back, the mother could indeed "coach" Eve into doing nasty approaches, wearing slutty makeup ans revealing outfits, masturbating freely at home while watching porn in the living room, talking with nasty words, and even encouraging her to become pregnant with the son's child. Here, we have an opened door to imagine a twisted mother manipulating her young daughter into becoming an extreme pervy teen :let's not waste it !
And for those who don't approve : really, guys, it's just a story with fictional characters. To each his own fantasies, nobody is hurt here.
I'd say : go for it
Luxee, and just avoid the common plot and characters that everyone do know after so many incest games.
