GREAT START When I firs began attempting to get my wife fuck other men I did a very similar thing...then with a very realistic rubber dildo I started fucking her with it and telling her to pretend it was another guy...I then encouraged her to bring herself to orgasm using the dildo while I would whisper in her ear how beautiful she looked with that guy's cock in her pussy. I continued to encourage her until finally she accepted a date from a guy at work. She phoned me that she would be late one Friday night after work and when she finally came home (very, very late) she had been very well fucked by the new bull. She told me all the details of her 'date' while I ate her recently fucked pussy. It all took off from there!
If your wife gets wet when you talk to her about fucking other men, then you know she REALLY wants it to happen...just have to get her to admit it and keep reassuring her it is what you want. Try to create opportunities for her to cuckold you. Go out for takes with a male friend, encourage them to dance together and later bring him home for a 'night cap'. If they seem to like each other, then find an excuse to leave them alone for a while and see what develops. Whisper in her ear that this could be her chance to make your dream fantasy a reality, and how you will lover her for it if she makes it happen. Good luck and keep us posted.
