You have my complete sympathy, as I know exactly what hassle your two have gone through. I know from many years of experience in girlfriend and wife sharing that finding other men to fuck your woman is not easy. Bars are an uncertain and unromantic place to look. We found swingers, swinger parties, and most adult hotels a waste of time—worse still, often a bad time. Sex websites do list many men eager to fuck, but many are sleazy and too eager. Friends are a little difficult because they know your other friends and family and they might not be your friends in the future. The optimal male buddy was one I knew well, but who wasn't intertwined with the rest of our friends. We had many wonderful MMF threesomes this way, but with everyone moving, they ended.
We were eager for more good times, so we were still on the hunt for new men. We tried a variation on the personal ad: a request for someone to help me photograph my wife. This work very well, indeed. The ad stated that I was trying to take boudoir photos of my wife, but I needed the help of a good photographer. We received at least eight answers to this ad and we invited half of them over, one at a time, for one night of photo fun. Our plan was to have my wife answer the door in a sexy, although not a too revealing outfit, usually a silk blouse and a short skirt and heels.
Next, we would show him some of the photos of her in lingerie that I had taken. The first dozen photos in the album were very revealing and soon they showed all, while the end included X-rated pictures, including photos of her with other men. After sitting with him and showing him only the first half of the photos, she and I both left the room, leaving him alone with the book, while we went off to get some drinks and snacks for all of us. This gave him time to stare at the last photos in the album. When we returned we would talk about backdrops and lighting. Once we decided on a course of action, she would go off and change into some lingerie. She then pranced around in increasingly revealing outfits, until she was completely naked.
Our code for her letting know if she wanted to be fucked by him was for her to tell me that she wished she had bought the red panties and bra set at the store earlier that day. If I didn't approve of the fellow, I would say that we could buy a different bra later. More than half of the time, she lamented not buying the lingerie. She surprised me with her choices; it wasn't always the most handsome or well-built man that she would to open her legs to; mercy fucks from her were more common than I would have ever expected.
I started taking all the photos, with him holding the lights or offering advice. But at some point, I would hand him the camera. I would ask him to take close-ups of her breast and pussy, as I held the lights. While he was snapping away, she would ask him if he thought her pussy lips were too small, which then led to him complementing her pussy. Often, he would slyly fondle her, while pretending to adjust her outfit.
While I made a trip to the bathroom, she told him that being naked in front of him had made her unbearably horny, and then she asked if he would be willing to make love to her, if I approved. They often said yes, but not always. When I returned to the room, she would ask me if I wanted to take some action photos of her and our photographer friend. And I never said no.
