Imagine your wife's best friend coming over to your house, waiting for your wife to get ready. Now you are sitting with her in your living room and slowly she starts seducing you, revealing she actually likes you a lot. She is getting bolder and bolder. After a few minutes of seduction she takes her panties off, sits on your already hard cock and rides you. "Oh yeah, fuck me fast before she gets ready. It will be our naughty secret, ok?" ... Would you do it? Would you fuck her or would you resist?;)
