This is a great example of how to get your girl hot and bothered by the mere mention of her name. I am not going to tell you to talk to your step mother in an intimate manner to get her to go upstairs with you because chances are that she would kill you or at least think it was inappropriate. But if you want to get your girl hot and bothered so you can seduce her like a stallion you have to whisper her name. The best way to do this is to use some sort of sexy whisper language like, "My sweet stepmother, please help me with my promotion. My little sweet thing, come on let's go upstairs.".
