She's Into My Wife

Me and my wife love to treat ourselves when we get the chance. We are a busy couple with kids and careers but we come back to this same hotel a couple of times a year. We have this same fantasy every time we visit our favourite hotel.
Me and my wife sit in the hotel bar, both a little tipsy from a drink. We meet a nice, cute little curvy woman in the bar and we start talking about random stuff, and we have a great time. There is a special tension in the air, it almost feels like the woman is coming on to my wife..
In some way we all three end up in our hotel room for a glass of wine...
This ends with the secret woman seducing both my wife and me....
