At first it was just a joke, you laughed and joked together. You were "almost" friends, he fucked your wife and you watched. Whilst, frustrated and excited, you jerked your pathetic little cock. But then everything changed right? A thought crept in...and you started wishing that the mouth into which that big throbbing cock was shoved was, no longer your wife's but yours...or yes you did. Now you're just a whore too, a slut greedy for cocks, competing with your wife to see who sucks it better. You want to feel the cum running down your throat. I'm making you your wife's bitch.
