Not being able to get your wife pregnant is slowly tearing your marriage apart. You’ve tried everything and as a last-ditch hope, you found a surrogate. But, the surrogate just dropped out and now you’re lost for what to do. Confiding in step-mom, she tells you she wants to do anything she can to help you give her a grand-heir. Anything at all. But the thing is, they’d never allow it officially of course, because she’s your step-mother. So you’d have to do it privately. No eggs in petri dishes and sperm in tubes. It would have to be done the old fashioned way and well… your wife might not like it, so we’d have to keep it secret. You decide it’s worth the risk to save your marriage and you prepare to get step-mom pregnant then and there. It starts out clinically, with both of you feeling uncomfortable and awkward, trying not to touch or look too much. But when it seems like it’s not working, step-mom tries a different approach and timidly begins dirty talking you. As you look your own step-mother in the eyes and fuck her, a whole flood of feelings arise in both of you that you didn’t know existed. And as it gets heated, step-mom starts saying all kinds of filthy, depraved things to get you to spill your seed inside of her.
