Perturbation domestique

Your step-daughter's best friend has come over to spend the night. She decides to stay behind while your step-daughter and wife go get ice cream. The next thing you know, she's got her pussy out, fingering it while telling you how hot you are for still being the only married man she's met. Later that night, she still can't get you out of her head, and she wakes you from your snores to get a rise out of you.... will you cave? Your wife is next to you in bed... what if she wakes up?
