Watching my friend's step-dad whack off

Your step-daughter's friend stopped by, but she is not there right now. In fact, it will be an hour till she is back home, so it is just you and Diana for a little while. She takes the opportunity to confront you about the fact that you stare at her. Diana tells you that she does not mind that you stare and that she sometimes comes by just to see you. Would you like to show your dick to her? Diana would love to see it. In fact, she wonders if you would like to play with it for her. Of course you would!! She lifts up her skirt and shows you that she is wearing no panties. That pussy is shaved clean and you have often thought about how her pussy looked. Now you know and your dick is super hard as you get a closer look at that pussy. Diana confesses that she peeked in the other night and she saw you whacking off. Were you thinking about her then?
