There was a time, even after she had begun cuckolding you regularly, when your wife would still very occasionally have sex with you, but even those infrequent "pity sex" sessions stopped a few months ago, and now she and her boyfriend see each other at least three nights each week, while you have to live pussy free and often alone.
You could sense that things were starting to become serious between your wife and her boyfriend, but she has never told you who he is and he's never come to your house before while you were there -- until today. As you hear the doorbell ring, your heart skips a beat, and then you head down to greet him.
Your wife has been cuckolding you for almost three years now, and she loves to tease you about how different her sex life is now from yours.
