I'm your step-daughter's best friend and I just want to thank you for letting me stay with you over the summer. I want to show you how much I appreciate you and offer to earn my place in your house. I noticed your wife doesn't give you the attention you deserve. I will. We don't need to cheat, you can just jerk off while I strip for you. I see how you look at me when you're wife is away. It's ok, your wife and step-daughter are in bed. It'll be our little secret
