[M4F] what are you doing, (step) daughter?

You are in a age where your thoughts revolve around sex and getting fucked. You, on the other hand seem to think that sex should definitely lead to pregnancy, so when your mom tried to support you getting birth control, you strictly rejected.

Now... You are feeling that your (step)dad might be a suitable donor to get your first baby from.

You just need to figure out how you can make him cum inside your fertile womb.
