My wife Angeline had had plenty of sex partners before we met, sometimes with several lovers in her stable at the same time. Normally she slept with several different men every week, swapping them in and out as she pleased, always informing each about the others. That's how she explained things to me after adding me to her line-up. It took a couple of years before she dropped all the others and we became exclusive. But after some years, she realised that monogamy just wasn't a good fit for her and started looking for ways to have other partners yet not imperil our marriage.
A solution was close at hand: we were both artists, and one of our private drawing groups met weekly, alternating ourselves as models to keep expenses down. Angeline is one of the eight or so women in the group who take turns posing nude for us. (The dozen or so men also pose nude.) The women range in age from their mid-twenties to late forties, except for Angeline, now 62. The men, including me, are twenties to 66, my age. She's exceptionally attractive, and her maturity carries with it that certain elegance highly prized by artists. We model sometimes solo but often with a partner of the opposite sex.
As the senior and founding members of the group, the other artists look to us for direction and trust our judgement. So about ten years ago, on an evening when it was her turn to model, Angeline, after stripping off, addressed the assembled members of our group, suggesting that we push the boundaries a bit by making the male/female poses more explicit. (Standing there as the only one naked, she could probably have talked anybody into agreeing to anything she wished.) She explained her idea: she would like to do intimate poses involving penetration, one pose with each of the men who would be willing. She explained that to pose that way with just one might lead to complicated feelings, but by taking multiple partners for the evening any feelings of emotion or jealosy would be minimised. And since I'd have full knowledge, this would not be cheating on me, her husband.
The assembled artists gave tentative agreement, with the proviso that the scheme could be altered after trying it out. Of course, being already naked, she put herself forward as the first to take this bold step of posing with penetration, and asked for male volunteers to pose with her, and why not start this evening? There was no shortage of volunteers, as every male there had been visually enjoying Angeline's sexuality for several months by then.
We started the session with the usual one-minute solo gestures. After about twenty minutes, it came time for the first long pose, so whilst her first volunteer was disrobing she reclined on the divan in the center of our rented studio, knees apart and slightly raised. So far, this looked like just one of her regular poses. Until forty-year old Malcolm, now nude, positioned himself between her legs and aimed his cock into her as we other artists directed them into the pose to hold for about ten minutes. When the timer sounded Malcolm withdrew his cock from my wife's vagina and the two stood up. (Of course I'd seen Angeline in coitus with many different men, but that had been many years earlier, but this was here and now, and every bit as beautiful as before. And I was getting even more of a rush!) Malcolm donned his robe and took his place at his own easel while Dave, a twenty-eight year old grad student, undressed and took his place beside Angeline. She got on all fours and asked Dave to spread her cheeks and enter her from behind, making it clear that she did not mean her anus. Once in, he was directed to withdraw by a couple of centimeters to afford a view of their genitals connecting. Trying to hold this pose, Dave became excited and announced that he couldn't help that he would soon ejaculate, and asked how to handle the situation. First glancing at me, Angeline looked back over her shoulder and told him to stay inside her and just let it happen, as there was no chance of pregnancy at her age. Dave went off just before the timer did. He then withdrew, leaving a strand of white silvery cum leaking out of my wife. One of the artists asked her to remain in position while he made a quick pastel sketch of her with the fluid running out.
When she finally stood up, then turned to all of us and asked for a few minutes before going into the next pose. She wanted us to discuss how things had progressed thus far, and to assess if we should continue. All agreed that we were on to something special, and that by all means we should carry on. With that settled, she looked me straight in the eye and, still dabbing the sticky mess of Dave's cum from between her thighs, asked how I felt seeing her once again penetrated by other men, indeed for the first time in our nearly thirty years together. I told her I loved, her, as always, and that I respected her for pursuing what she wanted, and mentioned that she looked even more beautiful having sex and that the resulting drawings would be really successful. Then I got to the real matter at hand: I sheepishly admitted that I got a sexual thrill whilst seeing other men admiring her naked body, and that seeing her fuck a succession of men just heightened the thrill. For her part, she explained that she hoped that the resulting art would be successful, but mostly that she was really happy to get back into having sex in public. She thanked everyone for not looking away as she was having intercourse, and reminded us that as artists it is our task to carefully study every visual aspect of the nude models set before us. Then she said to me that as each of the two cocks was sliding into her she tried to catch my eye as an assurance to herself that she was still mine. She thought it might help her if for the remaining poses I would either talk to her, hold her hand, or perhaps catch her eye, at least while the other man's cock was sliding in, then I could get back to my drawing. I agreed to do this, and walked to her and gave her a big hug and a loving kiss. It was good to feel her warmth and wetness against me, and to smell the sweet scent of her arousal.
With all this settled, she took the next pose, with a third male model, Kevin, a forty-six year old, who was already lying on the divan. I held her hand as she lowered herself onto Kevin's upright cock, her eyes locked with mine and I felt a flood of her love coming to me. Once she was in the cowgirl position, they shifted slightly to get so they could hold still for half an hour. Then her eyes shifted away and I took that as the signal that I was free to sketch. The view of her labia enrobing Kevin's cock, along with her clitoris very much on display, made for some very explicit drawings.
Our son and daughter and their respective spouses, all artists, were attending that evening. Even though our son had seen his mother nude on previous evenings, and indeed tonight he'd watched as she fucked, she now told him that if he noticed her clitoris wet and extended out of its hood he was to move his easel to where he wouldn't see it. (He quietly relocated to one side for just this pose.)
At the end of being with Kevin, Angeline came over to say that locking eyes with me helped her a lot, but she thought that maybe for the next pose I could come over and kiss her as she took in the next cock.
It was time for the break, so she pulled on her robe and walked around amongst the other artists and their easels to see their work, and to visit the loo.
The break concluded, she handed me her robe and set up for the next pose. George, who was half her age, was lying on the divan and Angeline positioned herself over him. She asked me to come and kiss her as she maneouvered George's cock into herself. We held the kiss until she slid completely down, then she brought his hands up to cup her small breasts, but not before offering me one of her nipples to kiss. She smiled at me as I returned to my easel to start yet another drawing of my wife fucking another man.
