Your secretary finds condoms in your pocket. After questioning you, because she knows that you and your wife are trying to get pregnant, you admit that it's her that you really wanted to fuck. She's game, but says that you don't need a condom because she is on the pill - house scandalous would it be for the boss to get the secretary pregnant? She strips for you, and rides your dick - both cowgirl and reverse cowgirl her giant ass twerking on your cock. But oops.. she lets it slip that she's actually not on the pill. She wants get pregnant instead of your wife. You're way too turned on to stop and end up giving her a big fertile creampie.
