Synopsis: Amanda and Mark Green already have a form of an open marriage, where she is allowed to play with other men under a specific set of rules. She meets an ex-Marine named Greg, and his dominant nature leads to the two of them forming a special sexual chemistry. They have a long-standing arrangement that works great with her marriage until the day comes that some bad choices are made...

“I will definitely have to finish those server patch installations after five PM so as to not interfere with the office staff, so I won’t be home until probably six thirty or so,” Mark Green explained to his wife, Amanda.

“That’s no problem,” came the somewhat sleepy voice on the other end of the phone call. It was nearly three thirty PM, which meant that Amanda hadn’t been up for long. “That’s how you said it would probably work out.”

Amanda and Mark worked opposite shifts; he was an IT Manager, with a normal Monday to Friday day shift. Amanda was an ICU nurse who worked three twelve hour night shifts per week, seven PM till seven AM. The fact that the hospital required her to work so many holidays and weekends per year could be annoying, but even with accounting for a lost day due to having to sleep and catch up in each cycle, she still got an effective extra off day every week. In addition, she could basically pick up overtime shifts at will, which made paying for vacations or special occasions a cinch, and she got broad leeway from management to schedule when she wanted to work.

“Did you hear back from the new guy? What was his name again?” Mark asked.

“Greg,” Amanda replied. “I did – he texted me this morning. Since you won’t be home before I leave anyway, I figured that today was as good a day as any for an initial face to face, if that’s okay with you,” she explained. “He suggested that I meet him at the McDonalds off of exit eight on my way to work this evening. That way, it’s nice and public, we can chat and see if there’s any chemistry.”

“That sounds like a smart plan,” Mark observed. “I take it this means that you are for sure done with the young guy?”

“James,” Amanda replied. “And yes, I’m done. It was fun while it lasted, but he’s been pretty clingy for the past couple of weeks. Him telling me that he thinks he may have real feelings is the end of it. You know that.”

“I know,” Mark agreed. “And you are right. There’s no sense in anyone getting hurt. It just kills me how guys blow up a good thing like that!”

Amanda laughed, then her tone turned mock serious. “Are you telling me that you are blaming them for falling for me?”

Mark sputtered. “Er… uh… no, of course not! You’re fantastic, you know that. I’m just saying that they get no strings attached sex, you think that they’d be happy with that. But no, they want more and end up with nothing.”

She laughed again. “I knew what you meant, it’s just fun to make you squirm a little. Look, the bus will be here soon, so let me see the kids. I love you, I’ll talk to you later. If I don’t hear from you before then, I’ll call before I walk in to work and let you know my first impressions.”

To the outside world, the Greens looked like a very typical little family. Mark was thirty, Amanda was twenty-eight. They had two children - a daughter aged eight and a son aged six. The kids were involved in baseball and dance, the parents juggled the various activities and made the schedule work. The Greens did family outings and vacations together, the couple went on “just the two of them” dates and weekends, and all the world saw a postcard example of the nuclear American household.

Most of their conservative friends and family would have been shocked to learn that they were not, in fact, a completely typical family; Amanda had sex with other men with Mark’s full knowledge and permission, and had been doing so for better than two years.

You see, Amanda and Mark had gotten married very young, and Amanda had quite truthfully not been ready for the commitment. She had grown up in an ultra conservative, extremely repressive household where even to this day, Amanda’s mother would whisper the word “sex” in conversations with her adult daughters. Amanda had grown up thinking that sex was bad and dirty, only permitted grudgingly for making babies, and felt shame for any sexual urges or desires. She and Mark had explored so much, she had really struggled with changing her attitudes… but her views on sex remained unhealthy, to say the least.

In some sort of self-destructive rebellion, Amanda had cheated on Mark a few years ago. The affair lasted for a couple of months, until in the middle of a petty argument, she broke down sobbing and admitted the whole thing. It hadn’t even been a guy that she was attracted to, but he paid her attention, she craved validation, and she ended up doing things she bitterly regretted.

The affair had been very difficult on their marriage, but Mark dearly loved his wife and was determined to make things work. They spent a lot of time in discussions, in opening up to one another, in exploring the root causes of the infidelity - and they seemed to have made real progress.

So when Amanda cheated on him again, Mark was devastated.

In fact, it happened several more times. She never had another true affair, but Amanda would hook up or fool around with another guy – sometimes even at events where Mark was present. She would immediately break into tears and confess no later than the day after (often even the same day), she would feel genuinely horrible about what she had done. But no matter how genuinely contrite she was, no matter how much she cried, no matter how bad she felt - it always seemed to be only a matter of time before she cheated again.

It felt like the only possible future for the Greens was one where the pair was divorced. Mark simply could not continue when his wife seemed pathologically predisposed to cheat. He loved his children dearly and was willing to do anything to prevent them growing up in a broken home… but how could he live with a woman that he could not trust?

Then one day, he had a desperate idea.

Mark told Amanda that he was willing to freely open up their marriage for her, as long as she would agree to a few rules about how it would work. He would allow her to have sex with other men as she saw fit, but that to do so, she would have to remove all lying, all sneaking, all deception from the equation. If she was going to fuck other guys, she had to let Mark know who she was with, about how long she planned to be gone – and if the plans changed, she had to let him know about it.

She would be required to always make it a point to come home after and have hot sex with him after she met the other guy – and it could not be duty sex, no acting tired or disinterested; she had to be enthused and into it. She was not to do any sex acts with other guys that she would not do with Mark or that she had yet to try with him. She was to always be open and tell Mark everything that she had done, there would never be any secrets about the guys or the sex.

She was to make an effort to include him when possible – this meant that from time to time, they would do threesomes together with other guys.

And finally, Mark reserved the right to veto any sex act, any particular meet, or any particular partner.

Amanda tearfully agreed to the conditions, grateful that her husband loved her enough to try to find a way to make their marriage work despite her compulsions. The next weekend that they went out, she ended up giving the bar’s bouncer – an off-duty police officer – a blowjob in his truck behind the bar while Mark stayed inside and played darts. They then went and picked up a guy the next night and had a threesome.

To tell the truth, Mark absolutely despised the idea to begin with. It was humiliating beyond belief to sit there and throw darts with strangers while his wife sucked some other guy’s dick. Watching her beautiful face contort in pleasure while she took a different stranger’s cock inside of her made him literally sick to his stomach. Thinking of her fucking other men was emasculating, nauseating, infuriating.

But if he didn’t allow it, the marriage would be over. He could not live any longer with the betrayal and the lies and the not knowing. If he didn’t open his marriage like this, he would have to leave it altogether, and Mark really didn’t want to settle with seeing his kids every other weekend for the next ten to twelve years.

So Mark swallowed his pride – and more than a little of his self-respect. Even so, after that first weekend, he didn’t know if he could keep doing it; the mental images, the knowledge of what his wife was doing was absolutely driving him crazy. In desperation, he started surfing the internet, finding forums where men shared their wives with others, and he began reading their stories. He was surprised to realize that some men got off on the idea of their wives having sex with others more than anything else.

And so, in an act of self-preservation, Mark made a choice to focus on the sex itself. To view his wife as something like his own personal porn star. To take solace in the fact that no matter what she did, she always came back to him, that her heart belonged to him alone. And to focus on the fact that whenever she was with other men, he was rewarded with truly outstanding sex.

Sure enough, Mark slowly began to not only accept, but to even seek his wife having sex with other men to the point that it became his absolute strongest kink. There was a clear difference in Amanda’s mentality and libido when she was playing with other men, and Mark was the definite beneficiary of it. Somehow, the two of them managed to move forward, and over the two plus years that their marriage had been open, they had grown incredibly close.

Along the way, Amanda had developed her own rules. Most of the men that she had sex with were guys that she and Mark picked up in a bar for a threesome, or were those she met and screened online. If a guy was selfish, pushy, didn’t treat her with respect – she would never meet him a second time. Over time, she had enough marginal to poor experiences that she had moved to a system of screening guys in a public place first; if they could carry on a conversation and she walked away from the meet with a positive feeling, only then would she agree to sex.

Furthermore, Amanda made it abundantly clear to the guys that she was married, that this was only casual sex for fun. She would mention her husband often, make it clear that she was emotionally unavailable – she had once let a “friend with benefits” situation get out of hand, and the mutual feelings she had developed with a married man had led to a messy, emotional end to that arrangement. So from that point on, as soon as there was any hint of the guy catching feelings – or if she found herself growing attached at all – she would end that situation.

This had been the case just a few days ago with James, a recent college grad who Amanda had played with for about six weeks. The two of them would hang out, watch a movie, have sex. It had been easy, superficial fun, but James confessing that he was developing feelings had prompted her to immediately cut it off. Mark had seen her do that before, and he was extremely confident that she would never accept a call or text from James again. That’s just how it had to work.
