"Temptation" by D.A. Ignatius (DarkNites) (jash@kuhub.cc.ukans.edu). "The CEO of Fieldbrook has to be at this charity ball." So says the husband. But the wife of the CEO would rather ball the CEO than go to the ball. Therefore, she tempts him at home before they leave for the festivities. He makes it to the ball and finds another beautiful woman coming on to him while he is at the podium - and he with his wife's lipstick barely dry on his cock! His wife wards off this predator and continues to flirt with her husband. But has she gone too far? She doesn't care if they are married; there is a limit to what it is legal to do under the eyes of a hundred people.
A limit - but a very generous limit. She is so relieved that at least this isn't going to be a repeat of the Ladies Room Experience that she doesn't even mind when he tears off her panties and plunges into her in the room at the Regency. Based on personal experience, I have no problem believing that this story is very, very plausible.
