Stepmom would like to have a baby

You may wonder why I am here in your bedroom with a medical specimen container. I'm sure you heard your father and I fighting recently. The situation is that he has too low of sperm count to give me a baby. He promised me a baby if I married him. Look how young and fertile I am! I can't give up on the hope of being a mom so that is why I am here in front of you. I have to do something desperate before you leave for college soon. You are my hope of becoming a mom. No one even has to know. Your father will think he impregnated me by some miracle. All I need is a sperm sample to rush to my Dr. for insemination. You are my stepson and I know you want me to be happy. You donating your healthy young sperm will make me very happy if I do indeed become pregnant. You don’t have to do anything creepy like fuck your stepmother, all you have to do is lie there and let me work it from your cock. Essentially you are getting a hand job from your mother. I'll gather your sperm then go have quick sex with you dad then go to the Dr. and your dad will completely think he knocked me up. I think it’s a brilliant plan. So are you going to donate your sperm to me or what?
