Please make me a step-mother and impregnate me

I'm your longtime friend visiting you from out of town. We're catching up on the good times when I mention that lately, I've been thinking of becoming a step-mother. You ask who the lucky guy is and I tell you that I've actually thought about asking YOU. I'm more than capable of handling the job on my own but I need sperm. I know you have an impregnation fantasy, so this is your chance for it to come true! I quickly drop my top to reveal my two compelling arguments: my breasts! You give in to my seduction and I climb on top of you. I want you to make me a step-mother... impregnate me! I want that sperm to go deep inside me. I'm ovulating right now so my chances are high. If we fail? We have the whole week to keep trying!
