Chapter-1: Introduction
Lew and Esther had been living together and married a long time; and unfortunately, the sex was getting boring. For several years, they engaged in "pillow-talk" -- i.e., fantasies about sharing and group sex. Esther understood that Lew was eager to see her with another man or woman; and she'd indulge his fantasies to get him off -- but made it abundantly clear that she was not interested in realizing his fantasies. Surprisingly, after 25 years Esther relented (or gave in to his incessant requests). They tried swinging by engaging in some MMF 3-ways with 3 separate men and even an MFMF with a very sexy married couple where Lew got to see Esther get and even give oral with a female while her husband and he watched. Lew especially enjoyed 69'ing with her as she got fucked doggy -- watching the action as close as possible. At this point, it probably makes sense to help the reader imagine what she looks like: 55 years old, cute, blonde, 5'2", 101 lbs., 32A with pale pink nips, and a shaved mons.
However, an unfortunate result of this exploration was Esther complained about being self-conscious or inhibited being watched by her husband and insisted that going forward, they would have an "open marriage" and play separately. In addition, she made it clear that she was no longer interested in any sexual activity with her husband. They formed some ground rules which included "home turf was off-bounds," not staying out late at night (let alone overnight), and no weekend play when both would be available from their busy careers. In essence, one needed to find playmates during the weekdays or early evenings.
On one occasion, before the ground rules were in place, and one might say because of this incident, Lew came home earlier than expected and discovered a strange man socializing with Esther. No "hanky-panky" was going on, both were fully dressed -- however, it was somewhat awkward with introductions being made. It appeared he was somebody she knew from work who happened to be in town on business. It was clear that the fellow had designed on Esther's petite, sexy body.
In any event, after the brief introductions, Esther said, "well, we should be going!" At which point, they gathered some stuff and Esther and the "associate" departed. The reality became apparent when Lew looked through the peephole in the door and saw them passionately kissing in the hallway on the way to the elevator -- and no doubt his hotel. She returned home a few hours later looking rather pleased with herself, albeit a wee bit disheveled. Lew and Esther then agreed to the "home-turf's" being off-limits to avoid future awkward embarrassment.
Chapter 2: The Plot Thickens
This pattern went on for a number of years. Lew found playmates here and there and even attended a swing club, sometimes getting to play with a few different women. On one occasion, he even was proud be make some gal he had just met nude on the mattress squirt for the very first time!
Lew had to admit he missed making love with his wife -- it was now several years. He got to see her nude in the apartment (she was not self-conscious) -- but sex was off the table. He had no idea how often or for whom she might spread her legs?
One day, Lew got a call from Max, a guy he knew from college who gave him an amazing report. It seems that he had been introduced to Esther by a friend named Dick, a swinger he knew! Dick was raving to his friend what hot piece of ass Esther happened to be -- and evidently eager to meet new playmates. Max had never met Esther but was aware from having followed Lew's facebook page, that Esther was his wife -- not having any notion previously that she was a "hotwife!" Not wanting to spoil his chances to fuck her, Max did not let on that he knew who she was, let alone an old friend of her husband.
