Stepdaughter Wants A Creampie

You are about to get up when your sweet and innocent stepdaughter comes in and wants some advice from your wife. She is not home so you suggest maybe you could help her. She doesn't think you can but you insist so she tells you that her clit is super sore from her new vibrator and needs to know what to do! Little too much info but since you asked she wants your opinion and to top it off she wants to show it to you! You get instant hard on and from there it just showballs a situation where she wants to know if you gave her a creampie. Few days later, your curious stepdaughter walks in again on you in bed and she tells you she now knows what a creampie is and guess what, she wants one from you! Can you turn this sex goddess away or obey her and give her a creampie she so badly wants.
