You knock at her door and confront her with what you saw. As her stepfather, you have to make it clear to her that this is not acceptable behavior. She is upset that you were watching her, but she wants to make sure that you do not tell her step-mom what you caught her doing. If she jerks you off, will you keep her secret? You agree and she takes your dick in her hand and begins to stroke it. She is such a pretty girl and she looks very much like her stepmother. Scarlet changes things when she demands that you work your dick yourself. At this point, she realizes that your cock is much bigger than her boyfriend's dick is.
