You probably would need a little time to set it up, but something that worked for me in the past was to find a potential bull through an ad in Adult Friend Finders. I met with the guy several days before and clued him in. I pre arranged to have him 'run into' my wife and I at a lounge and I introduced him as an old friend from college. I then had him sit with us and start flirting with her at every opportunity. She was loving the attention and I would leave the two of them alone at every chance I got to go the the bathroom, go make a phone call, etc. Eventually they started dancing together and things got interesting as he was really coming on to her now. I could see him holding her very tight, grabbing her around the ass and kissing her neck. Back at the table I managed to whisper in her ear that I wanted to invite him over for a take or two later. I also told her that it would be a good opportunity for ther to be as naughty as she wanted to, because he was real cool and could keep a secret. When I felt between her legs she was very, very wet down there, so I knew that I was having good results. Later the climax of the night was when he got to fuck her as I sucked on her toes...my wife went absolutely wild!!! She couldn't thank me enough the following day, as she had cummed like a horse that night while making love to the stranger with my encouragement and assistance! I never owned up to the fact that I had set the whole thing up, but it worked beautifully for me (and for her and the bull as well!)!!
