I've replaced your dick with something much larger, which stays hard as long as I want

Are you watching hubby? Are you paying close attention? Good. See how I've replaced your dick with something much larger, which stays hard as long as I want.

I don't need to have sex with you, now that I have this. Get used to watching, because that is all you'll get to do from now on. I'll let you jerk off while you watch me do this, so you get used to being aroused as you watch something other than your cock going into my pussy.

In time, I'll start bringing other men here to have sex with me as you watch and jerk off. By then, the sight of anything else going into me will make you hard. I'm going to train you to get turned on only when you watch me get fucked by other men. That's right dear. I'm turnign you into a cuckold, and there is nothing you can do about it now.
