Sims 2

I just remembered why I don't start a Sims 2 Legacy with a guy who sleeps around to the point of having three different fathers for his ten kids (look, don't ask): Because the dude he eventually married? Is now highly attracted to his step-son, who he has raised since toddler stage.

...oh god, plz talk me out of doing what I'm thinking about doing. *whimper*
