Caught Cheating: My Wife's Revenge

I slept with a woman on a business trip and two months later, my wife found out and it truly hit the fan, our sex became zero, an icy chill fallen over us. I confessed it all and slowly things got better. And then she booked us a sex weekend and that's where she got even, tying me up to a chair but then having sex with a guy she'd met while I had to watch. I loved it and so did she and it changed everything as this became her way of paying me back. Well, there could be worse now, couldn't there? But things got even better when we came to an 'arrangement' where we both were happy.
