Mommy And you- Impregnation

I don't wanna give tooooo much away with this one, but the basic idea I had was to make a film about your step-Mom who is trying to get pregnant, but your step-Dad is a useless bastard firing blanks. You just want to help your step-Mom so you innocently offer her a sample of your sperm.. but when that doesn't work getting her pregnant, you ask her if she thinks "natural conception" would work better? Your step-Mom struggles with the idea.. but it shouldn't take too much convincing... *sorry its a little shorter than my usual "Mommy and step-Son" videos, but I just didn't wanna drag it out longer than I felt necessary*
