Step-Son, why do you keep following me around the house? You know I won't give in to having sex with you! No matter how many time you ask I won't let your hard penis go into step-mommy's vagina! it's wrong! *time passes* step-Son, you know how I feel about fucking my own step-son! I'm not going to! You tell step-mommy if it feels good how can it be wrong. step-Mommy contemplates and decides to give into you.
