John and David had been friends for a long time. They had been in the military at the same time, although they served in different branches. John had been in the Army as a member of an infantry unit while David had been a rifleman in the Marine Corps. Circumstances had put their units near each other during various operations and they had developed a battlefield friendship. They had maintained the friendship after getting out of the service and had gone into similar professions. They were from the same general area -- which had also contributed to their battlefield friendship -- and they had settled near each other as a result. They had attended each other's wedding and regularly hung out together on weekends.
As is usual with service veterans, they regularly gave each other crap, but only in a friendly non-insulting way. It was impossible for them to feel insult from each other. David was a big man who inherited pattern baldness from his grandfather and had a "shiny dome" before he was 25. John was an average size guy who David regularly picked on for "not being a full size man." At five feet ten inches tall, and a fit 190 pounds, John had to look up to David's six foot four inch height. Just as fit as John, David weighed in closer to 240 pounds. Where John was pretty hairy and had to keep trimmed, David had very little body hair. Where John had a slightly above average cock, at 7", a handful around and circumcised, David had a much larger piece of equipment. His cock was almost 10" long and nearly as thick around as a coke can. His service nickname had been "stallion" and everyone knew why.
Their wives, surprisingly enough, were nearly identical. John's wife, Diana, was five feet six inches tall with auburn hair, C-cup breasts and a nicely rounded ass. David's wife, Julie, was five feet seven inches tall with darker brown hair, D-cup breasts and a similar round butt.
The two couples often hung out together and the wives got along very well. Many a weekend had been spent in one backyard or the other, barbequing, grilling, hanging out and enjoying a few drinks. Diana and Julie often shared a pitcher of margueritas as their husbands drank cold beers or the occasional mixed drink. David and Julie had a pool in their yard while John and Diana had opted for a hot tub on their private deck. On more than one occasion they'd had a few too many drinks and either gone skinny dipping in the pool, or soaked in the hot tub, all of them naked. The first time Diana had seen David naked her jaw dropped in surprise. Julie had seen the reaction and giggled, Standing near her husband, Julie reached out and took hold of David's manhood, shaking it and stroking it in Diana's direction. "Yeah," Julie had smiled. "It never fails to please."
"I bet!" Diana smiled back. But then she turned and did the same to John, stroking it in Julie's direction saying, "but this never fails to please and won't hurt me!"
As life evolved, Diana and Julie ended up working for the same retail company and went on work trips together as the job required. It wasn't often... maybe once each fiscal quarter. They would share a room and keep an eye on each other -- or at least, that's what they told their husbands. Truth be told, Diana kind of envied Julie's outlook when they went on travel. While Diana stayed "faithful," as she thought of it, Julie never missed a chance to dance and flirt with other men. Diana never said anything to David, but she told John everything. "It's just harmless fun," John would say. "It's not like she's cheating or anything."
"So you wouldn't mind if I flirted and danced with guys while I'm on travel?" Diana asked her husband.
"I don't think so," replied John. "Like I said... just harmless fun."
"Some of those guys take a lot of liberties feeling her up while they dance," Diana said carefully.
"That's between her and David I guess," said John after a minute. "If she doesn't tell him or she does and he doesn't care, it's not our business," John finished.
"You're awful nonchalant about it," said Diana with a teasing smile. "How would you feel if I flirted and danced with some guy and ended up with him feeling my ass or tits?"
John thought about that for a minute wanting to give her an honest answer. As he pictured it in his mind, he didn't experience any feelings of jealousy. In fact, the idea of it turned him on a little bit. Was that weird? Finally he gave her his answer. "I'm not sure it would bother me. I wouldn't want you to hide anything from me because THAT would seem dishonest; like you were lying about something. That would make it feel like you were cheating," he said. "But if you came home and told me all about it or told me about it on the phone during our goodnight phone calls, I'm not sure I'd care." He thought a little more and smiled, measuring how much he wanted to admit. "Heck, if it turned you on, you had a good time, and ended up in bed dripping wet and playing with yourself, I'd just be upset that I didn't get to watch!"
Diana smiled an evil grin, slapped her husband's shoulder and said, "Pervert!"
"Yeah," John smiled back, pulling her into a hug, "but I'm your pervert."
Hugging him back Diana smiled up at him. "You are... and I love you."
Time went on and before long the wives were scheduled for another trip. As the two couples lounged naked in the hot tub one Saturday evening, Diana brought it up. Taking a sip of her marguerita, at ease nude in front of their best friends, and wondering what David's reaction was going to be, Diana said, "So, Julie... John and I were talking about this trip and he says he doesn't mind if I find a guy to flirt and dance with one evening."
"It's about time," Julie said with a smile. "You've denied yourself the opportunity far too long, just watching instead of joining in."
"Yeah," agreed David. "I love it when Julie comes home full of sexual energy because she's been flirting, dancing and getting herself all worked up. She damned near rapes me when she gets in the door."
"You can't rape the willing!" Julie said with a grin.
"True," David agreed with a big smile.
"That's kind of the result I'm hoping for," said John. "That Diana will find some hot stud to dance with and get all worked up and then have to just sit on the frustration..."
"Literally!" chimed in Julie and they all laughed.
The conversation moved on from there and even though the topic was dropped, Diana knew she was free to mimic Julie's behavior when they were on travel from then on. Smiling to herself as she took another sip of her drink, she thought about what might happen on the trip and admitted to herself that she was looking forward to it.
A few weeks later the wives were off on their trip and the husbands were just hanging out, filling time. They found themselves at a local billiards hall, playing games through the evening with John pretty regularly winning. Every time John won he made a point of giving David some grief about it; about how a soldier would always beat a Marine in anything requiring good aim. David smiled and seemed to take the good-natured ribbing in stride, but, for some reason that particular evening, it was starting to get to him. So as they set up the balls for another game, he decided to push the issue. "How about a little wager this time around?" he said to John.
