Well, I gotta say, if they're going to throw in all kinds of kinks and shit. Why not go all out, and make it outside of the box.
For instance:
Having the daughter spy on the father, and get enough courage to finally go into his room. There she confesses her feelings, to maybe start a sexual relationship with him. Only to have him slap her hard across the face, and tell her, "To get the hell out of his room".
As she leaves crying and dejected, she passes Dumpster along the way and he heads straight for father's room.
Now curious she goes back and spies again, to find the father and Dumpster are naked on the bed, sucking each other's dicks in a 69 position.
I know, before you get your panties in a twist, he's bi-sexual, but more on the gay end though. Which gives a good reason why Mom is going after the MC.
I'm mean if you are going to have female bi-sexuals/lesbiens shit, then you can do what other devs don't and go outside the box....(What good for the Goose, is good for the Gander). Then have it reversed as well, and get Dumpster to be Dad's lover.
Just a thought...…..…..Lol!!…………………………..Peace!!
