8 XXX : Cuckold

I used to ask my wife to leave me dirty messages on my voicemail. She refused for years. A week after meeting her first bull, she left him a dirty message because he offhandedly mentioned liking that. She still refuses to do it for me and won't give me a reasonable explanation as to why. I know what it feels like to be denied while others get to have fun with her. When she comes home, kiss her deep on the mouth. Taste his balls and cock and cum. Worship her body like she worshiped his.
This is something I just can't understand, if my wife told me she gave something to someone else that she had been denying the supposed love of her life she'd be on the curb fast. Guess that's the definition of a hard limit.
She would lick my balls like that to start. Then I would train her to take my cock down her throat and lick my balls at the same time. You wouldn't know If she learns fast would you?
