Finally one day, when I was feeling great affection for him, I said: "Suppose there never was a FDOM agency in the government, and you only had to serve me like this and be subject to my management of your orgasms if you enjoyed it and wanted to be my personal slave like this... what would you do?"
He looked at me, stunned. Then he said: "So, you're finally going to admit it?"
"Yes," I said, "If you stay with me, I want you to stay because you want to, not because of some silly April Fools' ruse that I made up. I just did it to get to know you, I wasn't sure you'd go along with it this far..."
"It's okay," he said, "I've known that FDOM was a made up agency for a long time, ever since that first night, after you put this chastity device on me and I went home and googled it."
