This is part fantasy and part real. This particular incident never really happened, but my wife has told guys before that I was out of town when I really wasn't just to encourage them to ask my wife out. Most guys are nervous about hooking up with a married woman, but if they think the husband is out of town they tend to be much more willing to go for it.
She does more than tease
The way your wife dresses, how she flirts, how she ends the night always in the arms of another man.
All your wife's friends and husbands know you are a cuckold.
