Knowing that its your deepest fantasy, but that you can't get hard, oh wow

Oh, hubby! That's so sweet of you to tell me your deepest fantasy, you really want me to have sex with another man while you watch? I'd do that for you if you want. But in return, I'd like you to do something that's been a fantasy of mine. I want to put your little cock into a chastity device. It will keep you from being able to get hard, and prevent you from having any orgasms, you'd only be able to cum when I want you to, and in no time, you'd do anything I tell you, just so you could get out of it.

If you'd put one on for me, I'd gladly invite a guy from work over, and let him have sex with me while you watch. Knowing that its your deepest fantasy, but that you can't get hard, oh wow. I'm getting wet just thinking of it! Why don't you come over here and go down on me. You imagine that I just had sex with another guy, and I'll imagine that I've got you locked away in chastity.

Then I'll let you jerk off. When you're done and you get soft, I'll lock away your manhood, and we can make your dream become a reality.

Why don't you come over here and go down on me
