You've been dating my step-daughter for a while now and things are getting serious. I need to make sure that you are the right man for her and to do that, I need to find out if you are the right man for me. You don't mind if I get naked and explore your body, do you? Good. But there is one true test. You're the right man if you can get me pregnant. We may have to do this weekly but I need to be sure your cum is potent for her.
