Recently I decided to branch out in my photography. I'd shot plenty of subjects, but shied away from the whole modeling thing. After a few false starts, I decided to change course. Instead of asking a model to work with me and no nudity would be required (on a certain modeling site), I used Craigslist to find a willing female model who would bare all, sign a full release, and I would compensate her accordingly.
I chose a model who initially seemed conservative but said she would do nudity, no problem. I did not believe that until her second e-mail, which laid to rest any doubts about her feelings on nudity. She sent me plenty of full nudes she and her husband had taken. She is a beautiful blond with a great backseat, just to give you a visual. Her husband accompanied her on all shoots, which I was fine with (for legal reasons if nothing else).
Up front I admitted I wasn't sure how I might 'react'. I'd never been able to fully control myself in the presence of a naked woman, which was usually fine since we were going to fuck. They both thought it was funny, and said that was understandable

. Thankfully they were cool with it.
So the first (and second) shoot we did were great. She loved being naked, and took it upon herself to insert a finger into her pussy every now and then at the request of her husband. The strangest thing was to be taking a break, while I downloaded pictures she just stood around in the buff, sometimes pressing her naked chest against my arm while we looked at some of the photos. Rest assured my cock was practically erect the entire time, I just tried to re-arrange it every now and then, so it didn't stand out.
Anyway, after the second shoot, we decided to go to dinner. While at dinner, they explained they were in fact swingers (surprise!). They weren't the every weekend kind of swingers though, they just liked to have fun with friends. And they made a point to say they considered me a friend at this point. I did not think too much of it at the time.
Her husband e-mailed me with an idea, involving among other things, a double or triple blow-job set for their private collection. They said they might have trouble getting some of their friends over, and asked if I would be a stunt-cock, the POV shooter I guess you'd call it. I suppose my answer is obvious at this point. After some initial shots on the next shoot, while completely naked, she said "OK, let's do the blow-job stuff!". I was down to my underwear in seconds.
She took her time rubbing our cocks through the thin material of our underwear, occasionally using her teeth (don't knock it till you try it), and before long, she was alternating between us, sucking our cocks like a seasoned professional. We did that for awhile, then took a break. While sitting on the bed, checking the camera, cock pointed straight up and hard, she held up a condom as I was doing some test shots. She had a devilish smile on her face.
That was my first threesome. I had always dated girls who were reserved, and would never entertain the idea of a threesome. We did things I had only read in Penthouse Forum. We both took turns fucking her while she blew the other one. After an hour we had to call it. And yes, the whole time we took pictures (and no I can't post them, I respect their privacy) thanks to my remote. I must say, I felt honored to be inside of a model instead of just photographing her. Her pussy was just as tight as it looked, and her pussy was constantly juicing it up, no lube needed. She could do little more than moan as we filled her at both ends, and we switched off positions as we performed some of our favorite three-way postions you only see in porno movies.
We have had a few more 'private sessions' since then, but I never thought this would be the outcome.
Some may say I crossed a line, but I disagree. I was invited to join them, I never initiated the situation. I would like to hear any similar stories, or what others on the board think.
