Quoting: JUANITO
The main thing to remember is that no matter how insecure you might feel, or even if a touch of jealousy makes its way into the pit of your stomach, you must put it behind you and don't let it show
I wish I'd had that advice when I persuaded my wife to try a new cock. I can remember my fantasy developing just as you describe, the diference being I let my insecurity get the better of me. That in turn put Debbie off, and consequently, despite my encouragement, she has never repeated the experience. I so wish I'd held my nerve and let her see him again. Maybe then she would have gone on to a regular supply of fresh cock.
Whilst it still turns me on knowing some lucky young guy got to fuck my wife, it is the what might have been I regret.
So if you are hoping to embark on the cuckold life-style, listen to Juanito here - he's got it spot-on!
