You've known for a while now that I'm not satisfied, and maybe you knew before I decided to tell you the truth: I've been cheating on you. It's not just that your dick isn't big enough to satisfy me, it's that nothing you do satisfies me, so I started looking for other men to do what you couldn't. I started with one, and then another, and now I just can't seem to get enough. If you want to stay with me, you can, but the choice is yours - do you want to be alone, or do you want to be my cuck?
