Oh honey, you’ve probably noticed that your father and I have been a bit unhappy recently, and you are old enough to know what’s going on. We’re trying to get me pregnant, and well… I’m worried he just can’t do it any more! He can get it up, mostly, but I don’t think it’s going to work. We’ve been trying for MONTHS. I think he’s just too old. Not like you, you’re young and fit and… hey! I think I just came up with a perfect solution. You have been wanting to fuck your step-mom for years, right? Don’t try to deny it, I’ve seen you looking at me. It’d be perfect – you look so much like him that no one would ever suspect a thing.
