How to bring cuckold fantasy to fiancée

We can give you lots of advice on this but the one thing you have to do to start this correctly is, “Don’t talk about it during sex”! That’s all it’s ever going to be if you keep doing this because she’ll think that it’s only a game to play during sex to make things “hotter”. Take her to a nice dinner where you have a table where you two are alone, no ears nearby to overhear you. Bring up cuckolding to her as you’re holding her hands and tell her that you would like to see this go beyond bedroom talk, that you love her more than the whole world and want to see her having the time of her life. Explain that you’re not asking to watch her, you just want her to find a man to enjoy mind blowing sex with, with your permission as long as you meet him and feel that he’s the right man for her. If she sees that you’re being honest and aren’t trying to do this so you can play with another woman (be sure she understands this), she might give it some serious thought. Don’t push her, just let her think about it. If you haven’t heard anything from her in about a week, ask her if she’s had time to think about your dinner discussion. There’s much more from here but this is your start.
