Your step-daughter comes to show you her outfit before she goes out on her big date. You express irritation with her outfit being so revealing. You tell her that boys are going to think that she's only good for one thing... She acts confused, unsure of what you mean. She asks you to show her what it looks like when a man gets excited so she knows what to look out for. She quickly realizes she is enjoying teasing your cock and demands to see what it looks like when a man has an orgasm.
