You come in to check on me, I'm bummed out because your step-father won't be able to celebrate our wedding anniversary together due to his work obligations. I eventually admit to you that we were trying to get pregnant and tonight I'm at peak ovulation. I'm getting older and only have so many opportunities to get pregnant. You volunteer giving step-mommy your sperm the old fashioned way. By getting on top and creampie step-mommy in missionary. I'm so excited to get pregnant that I'm desperate for your seed. I become even more horny by your huge cock. It's way bigger than your step-father's. You're the real alpha of the house.
