Date night panties
How exciting would it be to buy your wife a sexy pair of panties, knowing full well that the first time she wears them will be to fuck another guy? To know that they will help her confidence and also help increase his arousal for your wife. As she puts them on and checks her self out in the mirror, felling sexy and ready to go out on her date. You know the next time you see the sexy panties YOU bought her, they’ll be soaked in her juices and possibly another man’s as well?
I know I know it was only a fantasy, a few videos on the internet, you didn't really want this to happen to you blah blah blah. That's why she tied you up. Because your pride would get in the way of what you really want. And, more importantly, what she reeeeally wants.
It was the first morning of your vacation, and your wife had said she was going for "just a short walk up the beach" -- but when she didn't return for two hours and when you saw the look on her face, you knew, even before she said anything, that she'd met someone and had sex. This was not the first time this has happened on one of your vacations. In fact, it happens on almost all of them, and you know, based on past experience, that there is a good chance that you'll be having dinners alone and sleeping alone every night all week.
