You have been away at University and have met a girl. You want to introduce her to your step-Mother but you have been keeping something a secret from her... you guys are getting married! When you announce the news to step-Mom, she doesn't react how you'd expect her to react. She seems disappointed almost? step-Mom calls you into her room for a "chat"... you need to make a choice step-Son. That silly little slut or the woman who has nurtured you for all of these years, the woman you have secretly lusted for. You agree that in actual fact, Step-Mommy is always correct. Nobody compares to your own step-Mother... all you need is step-Mommy.
