You're Going to be a Cuckold step-Father

I am visibly pregnant, rubbing my belly. I tell you about how I am pregnant and it's not by you, but everyone is going to think it is. All of our friends and family will congratulate us, but only you and I know you aren't the step-father. You will take care of me and pretend like it is, but really you are a cuck who can't knock me up.
