Two couples arrive at Playa del Maya, an adult's only resort near Cancun, Mexico, on the same day a few hours apart.
Dan decided to take a week's vacation to get away from the complications that had entered their married life when, months before, the boss caught Dan manipulating his sales numbers. Bill, the boss, threatened to fire Dan unless Dan and Jill agreed to allow him to spend the night with Jill. Finding no way out of their problem, Jill finally agreed to the arrangement, rationalizing that it was just one night and wouldn't mean anything.
Dan watched his wife with Bill through a one-way mirror. He was agog as his conservative wife at first resisted, then avidly encouraged Bill to fuck her with his long, thick cock. The sight of his lovely wife taking a large cock for the first time created both agony and ecstasy in Dan's mind. He could see for himself how his wife responded to a real man's hard, thick rod as compared to his paltry 4" weenie. Dan loved his beautiful wife and he was sorry that she had to settle for his little dick.
Jill was remorseful and reluctant to discuss her night with Bill. Dan had to admit that he was wracked with jealousy, yet aroused and understanding. He enjoyed Jill's lush, curvy body and her 38D breasts, while he knew she would always have to settle for his unimposing dick. Having finally experienced a real man's thick prick, Jill secretly craved that feeling again, but she would never admit it to her loving husband.
Dan sensed Jill's newly acquired taste for a big cock, but he didn't want to give his boss the satisfaction of a second round with his wife. Once was more than enough, Dan decided. He would never give Bill another chance to fuck his wife. The answer, Dan decided, was to seek ways to give Jill future experiences with other men, but never in a way that would lead to any repeat performances. She would get to experience bigger men without them threatening his marriage. A vacation at an adult resort held the promise of a relaxing time with the possibility that they might meet another man or another couple who might measure up to Jill's needs.
Ken and Renee were close to ten years older than Dan and Jill. They were empty nesters and Ken was in the process of helping Renee 'loosen up' and enjoy more freedom, especially in their sex life. Ken had always been more sexually aware and he wanted to help Renee overcome the many hang-ups she harbored from her early upbringing.
Over the past few years, Ken managed to convince Renee to sleep nude with him and even skinny dip in their pool with him once in a while. Renee usually wore a one-piece suit in their private pool, but she had developed the habit of sliding her suit off on their deck to dry her body. Ken enjoyed watching her standing nude on the deck and bending over to turn on the hose to water her potted plants before going inside to put on shorts and a t-shirt.
Little by little, Ken managed to move Renee to the point where she enjoyed oral foreplay and welcomed the use of sex toys during their lovemaking. The instructional sex tapes Ken ordered from an on-line site contributed to Renee's awakening to the point where Ken felt that she might actually agree to a vacation trip to an adult's only resort. When he suggested a trip to celebrate the conclusion of a major project, Renee went along, knowing how hard Ken had recently worked.
Renee looked at the Playa del Maya web site with Ken. She noticed that the resort had a nude beach area and quickly understood why Ken had chosen that particular resort. She let him know that she was definitely not going to remove her suit, and she didn't want him going to the nude beach area either. Ken agreed that she would call the shots and that he would go along with her wishes, but he also let her know that he was okay with anything that she decided she wanted to experience...anything at all.
Dan and Jill arrived at Playa del Maya first. Their accommodations weren't ready, so they strolled around the grounds and stopped at the pool bar for their first complimentary drink. Jill was shocked at the number of women who were sunning around the pool topless. Quite a few were speaking Spanish and various European languages. Dan noted that many other cultures accepted topless sunbathing and casual nudity.
Three women seated at a table near the bar were topless, enjoying fancy drinks. One was well endowed with large brown nipples. The other two had small, firm breasts, yet seemed unconcerned about their exposure. Jill studied the women briefly and shrugged. "It's certainly much more casual down here," she mused.
Ken and Renee arrived in the airport shuttle an hour later. Their room was ready and they were shown to a spacious suite in a beach side cottage. Renee could hear the sound of the waves lapping the shore as she opened the patio door and stood gazing at the azure water. "This is wonderful!" she gushed to Ken. "What a romantic setting for our getaway."
A bellhop found Dan and Jill and let them know that their cottage was now ready. They followed him and the luggage cart down a flower-bedecked walkway to a cottage on the beach. They would be sharing a duplex cottage with Ken and Renee, but neither couple knew that yet.
Ken slid out of his slacks and shirt, made damp from the ride in the shuttle. He pulled off his bikini underwear and walked out onto the patio. From the patio, Ken could see quite a distance up and down the beach. In the distance, he noticed that some of the bathers were lying naked on the sand while others frolicked in the surf. He yearned to join them, but he recalled the promise that he made to Renee and shrugged.
While Dan put away the contents of their suitcases, Jill opened the glass door and stepped onto their patio to take a look at the beach. She heard someone clear his throat and glanced sideways over the short railing that separated her patio from the one next door. Jill sucked in her breath as she saw the naked behind of a muscular man as he leaned on the front rail looking away down the beach. Jill stepped back inside, but studied the man next door. She noticed that he was tanned, but sported no tan lines where they normally would be. He turned and she got a quick look at his front side, including a thick, shaved cock that somehow reminded her of Dan's boss, Bill. Jill decided not to say anything to Dan because she didn't want to open up a discussion of that episode during their vacation.
...
The two couples discover that they are sharing the cottage and they have dinner together to get acquainted. Later, they split up and the men and women chat with their counterparts.
Jill and Renee find that they both have horny husbands who seem to want to see them loosen up and enjoy the laid-back atmosphere of Playa del Maya.
Ken and Dan get along well and decide to go to the pool for drinks and exchange experiences.
Dan eventually confides in Ken what he had to endure when his boss caught him adjusting his sales numbers, indicating that his boss is huge, while he is "somewhat below average." Ken is sympathetic and tries to tell Dan that size is an overrated trait. Dan goes on to describe what he saw through the one-way mirror and how his Jill had responded to a really big cock. Dan then told Ken that his solution was to try to give Jill new experiences, but without creating any long-standing relationship. "That's partly why I chose this resort," Dan admitted with a look of hopeful embarrassment.
Meanwhile, Renee tells Jill how Ken has slowly turned into almost a nudist. Looking around at the topless women nearby, Renee tells Jill that she's sure that Ken would be pleased if she were to 'do as the Romans' and shed her top while at Playa del Maya. Jill nods her understanding. "Dan worships my large boobs," she chuckles. "I'm sure he would be pleased if I dared to uncover them in public," she added. After a brief silence while both women were deep in thought, Jill said something unusual for her. "I think I could go topless if I wasn't the only one I knew who did it."
Renee studied Jill for a long moment. "Ken and I skinny dip in our own pool. Ken does it all the time and I sometime join him when it's really warm. We even went skinny dipping with some other couples one time when we lived back east. Ken wanted to do it again with them, but I was afraid to, so we didn't go back again. It's not that I'm overly modest or prudish, it's just that I've always felt that it was a bit weird or something."
"Evidently, lots of people disagree," Jill replied as she motioned to the many topless women nearby. "Maybe, if we both agree to do it at the same time, we could try going topless. I'm sure the boys would get a big kick out of it."
Renee stared into space, thinking back over the years to that evening with the neighbors. "Well, maybe we can, if you really want to, Jill. It might be easier if we tried it without our husbands around. Let's just play it by ear today, okay?"
Jill nodded her agreement. "I really shouldn't tell you this, but I need to tell somebody."
"What?" Renee asked with concern.
"A few months ago, Dan and I had a real crisis. He made a major mistake at work and his boss caught him. We had to agree that I would spend the night with his boss or Dan would lose his job!"
"That's terrible," Renee, gasped. "What a low down creep! What did you do?"
