You and I lead a perfectly vanilla married existence. We've been married for a few years now and we've settled into the routine of life. As with any couple, our sex life started off intense and has tailed off since but we still love each other very much and the sex is pretty good.

One day, early in the morning, you wake up and find out that I'm not in bed. It's 6am so I shouldn't be up. You walk around the house and to your horror and surprise you find that I am standing there, cock fully erect, jerking off to something on my phone. You watch me blow a huge load and horrified you sneak back to bed.

As you lie there you start to think about what you have seen. What was I watching on my phone? Why was I masturbating when we were still having regular sex? How on earth did I produce such a big load when I only cum regular amounts when I'm fucking you? And what should you do about it now that you've seen me masturbating....

The prompt can go many ways after this, but I have a couple of suggestions:

1. You confront me and demand to understand what was happening. You could play the angle of feeling cheated on or force me into sharing my browser history and taking things from there.

2. You decide to find out more before acting upon your new knowledge. You sneak a look at phone and its browser history. To your horror you see (any of the following) search terms:

• cuckolding
• raceplay
• foot fetish
• small penis humiliation
• cheating
• dating apps
• anything even more taboo that you'd like to RP

You then plot a course of action in order to deal with me and make me pay.
