Their first day at the clothing optional swingers' resort in Cancun, Mexico was eventful for Prudence and Trevor, the married couple from the UK. Prudence, a 35-year-old blonde personal trainer, while blindfolded had given head to four strangers in the resort's giant hot tub. She did it as part of a game in which she had to pick out her husband's cock from a lineup by performing oral sex.
Over the next day and a half, the Brits and their American friends, Greg and Julie, enjoyed everything Desire Resort had to offer. Prudence and Julie, a dark-skinned goddess in her forties who did not look close to her age, were attracting a lot of attention from the men at the resort. The women both loved showing off their fit bodies.
During the day, the couples participated in various organized nude and sexually charged activities. Trevor had been in the Royal Navy, so he controlled the small catamaran the couples took out on the water on their second day at the resort. The time wearing life vests was the only instance that both Prudence and Julie had their breasts completely covered.
At night, the couples wore costumes or revealing clothing they had brought for preannounced theme nights at the resort night club. In the back of the night club was a playroom. Greg and Julie had poked their heads in the room on their second night at the resort. The room was dimly lit and full of beds.
When the Americans looked in, there was an all-out orgy going on. Well beyond soft swapping (everything but penetration), there was full-on group fucking. Julie and Greg agreed that they were not ready for something that hardcore.
On day three, Prudence and her 50-year-old husband Trevor were enjoying cocktails as they sat on the mattress of a double-wide chaise on the beach. The back of the chaise was raised, and the British couple leaned against it, facing the water and Julie and Greg, a light-skinned black man.
The Yanks, holding drinks themselves, stood with their backs to the water. It was a sunny and warm afternoon. The waves were gently lapping against the shore.
Mexican beaches are technically public even if part of a private resort. Occasionally, guests from neighboring hotels would walk along the beach in front of Desire Resort. It was obvious that these looky-loos were taking their strolls because they wanted a glimpse at the type of nude vacation they were too afraid or too repressed to take themselves.
Julie
was wearing a red micro-thong bikini bottom. The front of the tiny garment was barely enough cloth to cover her small strip of pubic hair which her husband had shaved into the shape of an arrow that pointed at her pussy. She also had on a long white tank top that stopped midway down her backside, so the lower part of her curvy cheeks showed.
The red and white complimented Julie's brown skin. The arm holes of the shirt were so large that they revealed the sides of her breasts. And whenever Julie turned quickly, her right nipple was exposed.
Both men were wearing board shorts. Prudence, as usual, was nude. Prudence slathered sunscreen on her alabaster skin to keep it from burning. She enjoyed how the husbands watched as she rubbed SPF-40 on her nipples and hairless nether region.
The couples, who had known each other for a few years, always had a playful relationship. Flirtation and touching that would be inappropriate in polite society were constants in their interactions. But, until this trip, none of them had actually done anything sexual with a member of the foursome other than his or her spouse.
On day one of this vacation, Julie had her first girl-on-girl experience when Prudence went down on her in front of a crowd of resort guests in the hot tub. What had started as Julie pranking Prudence for a laugh ended with Julie climaxing from Prudence eating Julie's pussy.
Prudence then sucked off both Trevor and Julie's husband Greg in front of the audience. Trevor and Julie had agreed to repay Prudence by each giving her a public orgasm. Greg had agreed to double payment. Two days had passed since then.
After she downed the last of her drink, Prudence spoke. "Julie, you said something interesting after our encounter in the hot tub. Something about returning the favor and grinning in the groove. What exactly does that mean?"
"It's a euphemism," Julie responded, "The grin refers to my mouth and the groove refers to your... you know?"
"No, I don't know," Prudence said in her British accent.
Although, over the past few years, Julie had become at ease showing her body, she was still uncomfortable talking about sex. Julie explained at a normal volume, "It means that I will perform..." then whispered with a little embarrassment, "oral sex on you."
"What? Speak up, Dear." said Prudence.
Whispering even softer and more embarrassed, Julie said, "Cunnilingus."
Prudence said in a loud voice, "What? Seriously, between the sound of the waves and you whispering, I can't hear you."
Julie said quickly and at a volume loud enough to be heard by people walking by, "I will eat your pussy!"
"I heard you the first time. I just love hearing you saying it," Prudence said, then smiled.
"We all enjoy hearing it," said Trevor.
"So Julie, here and now," said Prudence.
"Here and now what?" asked Julie.
"When you promised to return the favor, you said 'just say when and where.' Well, here and now," Prudence said smiling like the cat that swallowed the canary.
"But this is a public beach. Someone might walk by. We might get in trouble," Julie said.
"Well, then I suggest you get to work and get me off quickly before you draw a crowd," Julie said with a smirk.
Trevor stood, moved next to the Americans, and said to Julie, "Here's a tip. Play with her nipples."
"Will that make her orgasm quicker?" Julie asked Trevor.
"It always has in the past," replied Trevor.
"Oh, and take off your shirt," said Greg.
Julie handed her drink to Greg and removed the tank top, fully exposing her bare breasts. She then was wearing only the tiny red bikini bottom. "Wait. Why did I need to take off my shirt?" she asked her husband.
"You didn't. But Trevor and I really like seeing your tits," he quipped. Trevor nodded in agreement.
"Come along, Dear. Chop chop. Time to get your grin in my groove." Prudence said to Julie with a smile.
Having never gone down on a woman before, Julie was not exactly sure how to begin. Her lack of experience paired with her nervousness caused her to hesitate for just a second. After which, she exhaled deeply and thought to herself, "Julie, just do it."
Then, like a cat, Julie pounced on Prudence. Julie looked at Prudence's pink nipples and, keeping in mind what Trevor said, Julie began sucking on them. Julie first sucked the left until it was thoroughly erect, then the right until it matched the left before moving back and forth between them, licking and sucking each.
