Testing the Limits

It started when my wife and I were on a vacation in the Dominican Republic.

It was February, and very cold in Boston, where we had lived for many years after our marriage. On the spur of the moment we had decided to get away to someplace warm, so we got my parents to come stay at our place a few days to mind the kids and booked a last-minute, four-day weekend trip to one of those all-inclusive resorts. Thirty-six hours later we were on our way.

We were both looking forward to the trip, not just because of the warmth in the midst of winter, but also because we both liked the idea of having some private time to ourselves.

For sex, I mean. If you have kids you know what I'm talking about: that when the kids come along, finding the time and energy to have truly enjoyable sex -- rather than the rote couplings we'd been having lately -- gets pretty difficult.

On the flight down my wife kept stroking my leg, and I got a hard-on, which she soon noticed, rubbing it with the back of her hand when no one was looking. I whispered into her ear, "How about I put a blanket over our laps and we can get each other off? Not quite the mile-high club, but still..."

She laughed and said no, but I could tell the idea turned her on a little bit. I thought that was a good sign we were going to have some excellent sex during the trip.

That was certainly the case at first. No sooner had we gotten into our room at the hotel, late Thursday afternoon, than she locked the door, stripped, and dived into the bed. I hadn't even put our suitcases down yet, but I dropped them on the spot, stripped off my clothes and dived in after her.

A delightful hour later we made ourselves get up, took a sensual shower together and went down to the hotel restaurant. There was about a 20-minute wait for a table, so we went outside to the patio bar to get drinks and wait.

It was warm and a little humid but breezy outside, and once we had our drinks my wife and I just sat there, holding hands and staring at the ocean.

At the table next to us was another couple, apparently waiting for a table, too. They were sitting close together, laughing quietly and touching each other frequently, and I sensed that they, too had just had an enjoyable romp in bed, or at least were planning to after dinner.

She was a very pretty woman, a slender blonde with long legs and small but nicely formed breasts that were shown off by the tank top and gauzy white wrap she she wore. She made an interesting contrast with my wife, who is a little fuller in the hips and breasts and even prettier, I thought proudly.

It was the guy, however, who really got my attention. He was strikingly handsome, with tousled blond hair, green eyes and a smile always playing about his lips. He looked very fit, with calves like a cyclist's.

At some point the wife saw me looking at them, but she gave me a friendly smile and said, with a slight Texas twang, "How y'all doing tonight?"

"Great," I said, "Glad to be at the beach instead of shoveling snow."

"So are we," she said. "Where y'all from?"

"Boston," I said. "But I'm guessing you aren't."

They both laughed.

"Nah, I'm from Houston," she said. "But this guy made me move north."

"Where north?" I asked.

"Chicago," she said, pouting her lips in a way I found very fetching. "It's a good thing I love him."

She squeezed his arm affectionately.

We chatted a few more minutes, and when they asked us to join them for a second drink, we accepted. But not long afterward the host came to tell them their table was ready, so they excused themselves to go.

"See you on the beach tomorrow," he said. "By the way, I'm Nick, this is Tanya."

"Sam and Vickie," I said.

We all shook hands and agreed to have a drink sometime over the weekend.

"Nice folks," Vickie said after they had gone. "She's pretty."

"Yes," I said.

"And boy is he a hunk," she said.

"Yes," I said.

She elbowed me in the side and gave me a mock-horrified look.

"Bad enough you notice other women," she said playfully, "No fair looking at their husbands, too."

"Um, well...."

She smiled and elbowed me again.

"I'm just teasing you," she said.

When they called us to the restaurant a few minutes later, we were given a table not far from Nick and Tanya. Without being conscious of it I took the chair facing their direction, and realized NIck and I were facing each other.

I tried not to look at him, but of course I did, and I was pretty sure he noticed. At one point he caught my eye, with that little smile playing about his lips, then leaned forward and whispered something to Tanya. She turned around and looked at me, an amused expression on her face, before turning back to Nick and saying something that made him blush.

Vickie and I, helped by a bottle of wine, got into a long enjoyable conversation, and for a while I forgot about Nick and Tanya. We shared a dessert and I had a cup of coffee, and when I finally looked around I realized that the restaurant had mostly emptied out, except for Vickie and I, Nick and Tanya and two or three other couples.

We were just about to go when Nick stood up and walked to our table.

"We just ordered a bottle of wine," Nick said. "Would you like to share it with us?"

I looked at Vickie. She nodded.

"That'd be great," I said.

We got up, walked over to their table and pulled up two chairs.

Half an hour and another bottle later, we were still there, laughing so hard that Vickie actually snorted, which made everyone laugh even harder. I noticed we were getting stern looks from the wait staff, so I suggested we call it a night.

Tanya stood up, swaying a little.

"We're going for a walk on the beach," she said. "You folks care to join us?"

Again I looked at Vickie, who was just as tipsy as Tanya but still nodded yes.

"Sure," I said. "Let me just hit the men's room before we go."

"Yeah, I better go, too," NIck said.

"Might as well make it a party," Tanya said, and taking Vickie by the arm she led the way to the women's.

The men's room had several stalls with louvered wooden doors but just one urinal, so I left that to Nick and went into one of the stalls to piss. When I turned around after flushing, Nick was still at the urinal, and his pants had slipped to his ankles. His butt was mostly covered by the tail of his shirt, but I got a good view of his thighs and calves, which were strongly muscled.

"You bike a lot?" I asked, and immediately regretted it, knowing he would realize I'd been looking at his backside. But Nick didn't seem bothered in the least.

"Two or three times a week," he said over his shoulder. "More if I can manage it."

He flushed and bent over to pull up his shorts, giving me a brief view of some well-developed glutes.

"I like to ride, too, I said, "but I have a hard time getting out more than once a week."

"We should see about renting some bikes while we're here," he said, turning around.

"Sounds like fun," I said, and he gave me another of those little smiles.

Rejoining the girls, we walked across the patio and down a graveled path to the beach, where a sliver of moon gave just enough light to see our way. Grabbing some towels from the rack at the end of the path, we turned left and walked along the water's edge until the lights around the hotel were hidden by a big stand of palms. The beach seemed to be deserted.

NIck and Tanya walked arm in arm a few paces ahead of us. Vickie, a bit drunker perhaps than the rest of us, leaned on me heavily, murmuring now and then about what she was going to do to me when we got back to our room. I started to get a hardon.

"Let's go for a swim," Tanya said.

"Great idea," Nick said, and before Vickie or I could say anything they had begun to strip.

I felt Vickie tense up.

"Ummm....I, uh...."

"Oh, come on," Tanya said playfully. "We're all friends here. Come on, Sam, help her out."

I put my arms around Vickie from behind, pulled her close and started undoing her blouse. She giggled.

"Not sure I want to get naked in front of them," she said.

"Hell, why not?" I said, slipping the blouse off her shoulders and unsnapping her bra.

Nick and Tanya, already naked, turned and headed for the water. It was too dark to see everything clearly, but I could make out the pale skin of their asses and of her chest when she turned toward shore. I felt my dick stiffen a ilttle more.

I pulled my shirt over my head and shucked off my shorts. Vickie had dropped her bra, and I couldn't help but reach over and cup her breasts with my hands. She giggled again.

"Stop it!" she said, although I could tell she didn't really mean it.

I kneeled down in front of her, hooked my thumbs in the waistband of her shorts and pulled them down. I wrapped my arms around her waist and buried my face in the lower part of her stomach, nuzzing the fur between her legs. My dick was getting really stiff.

Vickie wriggled out of my grasp and ran unsteadily into the water. Nick and Tanya were already in above their waists, and I could just make out Tanya's round little tits in the moonlight.

I followed Vickie into the surf, hoping Nick and Tanya wouldn't see how erect I was.

I needn't have worried. When the next wave receded and the water fell to Nick's knees, I saw that he was erect, too. He had a thick cock, not as long as mine but certainly impressive in its own way. And while it was hard to tell in the dim moonlight, he seemed to be looking at my cock, too.

"You boys are enjoying this, aren't you?" Tanya said, and burst into silvery laughter.

"Down, boy," Vickie said, swatting playfully in the direction of my throbbing dick.

Whatever inhibitions she had had about being naked seemed to have disappeared. I started backing away from her.

"You put yours down, too," Tanya said to Nick, making the same swatting gesture. He started backing away, too, but soon the girls had maneuvered us between them, backing toward each other until, in water barely waist-high, we bumped asses.

Truth to tell, it gave me a little thrill.

"Oops," I said.

"No problem, bud," Nick said. "But we're surrounded."

The girls closed in. Tanya got to Nick first. She put her arms around him, and for a fleeting moment I felt her hands on my chest. At the same time Nick reached back and, placing his hands on my hips, ground his ass into mine.

"Hey, girl, hands off my man," Vickie said. Evidently she hadn't seen what Nick had done.

As Vickie stepped into my arms, Nick and Tanya slipped away. As I half-turned to look, she wrapped her legs around his torso and they starting making out. I pictured Nick's cock sliding into Tanya's pussy, and the thought made me stiffen even further.

I felt Vickie's hand on my cock. She whispered to me, "Oh, baby, you are SO hard!"

Without answering I picked her up, carried her to shore, stood her on her feet just long enough to throw two towels on the sand and then dragged her down to the ground.

"I'm going to fuck you right here," I said.

"Oh, my God, are you kidding?" she said, but when I parted her legs and felt her pussy she was sopping wet -- and not from the ocean.

"But they're watching," she said.

"I sure hope so," I said, and slid my cock into her.

"Ohhhh," she moaned, wrapping her legs around me.

I heard splashing behind us as Nick and Tanya returned to shore. Nick spread a couple more towels on the sand next to us and lowered Tanya to the ground. As he settled in between her legs he rested his hand briefly on my ass. My cock twitched so hard that Vickie felt it.

"Oh, my God," she said.

For the next two minutes nothing could be heard but moans and whimpers from the girls, especially Tanya, along with my raspy breathing and Nick's grunting, and now and then those little wet fucking sounds. Then Vickie started making the high-pitched squeal she often makes when she comes really hard, which made me start to cum, and about the same time Nick roared that he was cumming and Tanya gave one great gasp and then it was over.

I gave Vickie a passionate post-fuck kiss and collapsed on top of her. Next to us NIck lifted Tanya off the towel and deftly switched places with her, and they made out briefly until Nick flipped her again and they made out some more.

For a couple of minutes we were all quiet, listening to the surf lap gently at the shore. Finally Nick disentangled himself from Tanya, got to his feet and headed back to the water. But Vickie and I were still locked together, and once in a while she gave my dick a little squeeze with her pussy.

I turned my head and looked at Tanya. In the dim moonlight I could just make out the pale skin of her breasts, with their dark areolas and still-erect nippies. I felt my cock twitch, and Vickie must have felt it, too.

"Down, boy," she said again.

'Ok, ok," I said.

I slid my cock out of her and got up. As I did I looked again at Tanya, and noticed that she was completely shaven between her legs. Her legs were slightly open, but all I could see between them was a dark space.

"I'm going to go cool off," I said, and turned to the water.

Nick was sitting in the shallows, just far enough so that the water covered his waist when the waves came in. I sat down next to him.

"You had a good idea there," he said.

I laughed.

"Yes, well, it was clearly the right thing to do at the time," I said.

"Was that the first time you had sex with someone else close by?" he asked.

"Yes," I said. "Although one time when we were camping we fucked in the tent several times with other people just outside, around the fire. How about you?"

"Not the first time," he said, but he didn't elaborate.

He planted his hands in the sand behind him and leaned back. When the water ran out after the next wave, I glanced at his cock, just visible in the moonlight. He was about half-hard. I looked away, feeling my own cock start to stiffen again.

Behind us I could hear the girls talking and giggling. I looked back, and noticed neither one of them had made a move to get dressed.

"You going to tell me about it?" I asked.

"Well, the short version is that we met another couple on vacation last year, and ended up in the hot tub in our room together, and drank several bottles of wine. After a while the other woman got up, took off her top and said Tanya should take hers off, too. So she did. And within 10 minutes we were all naked, and we ended up swapping partners and fucking."

I looked at his cock again, and it was fully hard. So was mine.

"Wow," I said. "That is totally hot."

"It sure as fuck was," he said.

Then, after a pause, I asked, "Is that where this is heading?"

He laughed.

"If you're thinking we brought you out here deliberately in hopes of another swap, no, we didn't plan anything."

He looked back at the girls.

"But it could go that way if you both wanted it to," he continued. "We have a hot tub in our room this time, too."

"You'd let me have sex with your wife?" I asked, turning around again. The girls were sitting up, closer together, and for a second I thought Tanya had her arm around Vickie.

I looked gain at his NIck. His cock was pointing skyward.

"Sure," he said. "Unless you'd rather have sex with me."

For a second I couldn't speak. I looked at him and saw, or thought I saw, that smile playing around his lips.

"I, um....."

"If you don't, it's cool," he said. "But I thought you might want to, the way you've been looking at me."

"Well, I ...."

I turned around and looked at the girls. They had gotten up and wrapped themselves in towels, and were gathering up their clothes.

"Come on, you guys," Tanya called. "We're going to sit in the hot tub."

"Looks like the evening isn't over yet," Nick said, getting up.

He started for shore, but stopped and said over his shoulder, "The offer stands."

His dick had softened a little, but not much, and he turned again to the shore. I stood up but paused to give my own cock a chance to come down.

"See, I told you," I heard Tanya say to Vickie. "He's horny all the time. Look at that thing!"

Vickie gave an embarrassed laugh.

"Here, give it a feel," Tanya said.

She must have taken Vickie's hand and placed it on Nick's cock, because Vickie gasped.

"What do you think?"

I waited to hear the answer.

Vickie cleared her throat.

"Well, I'd have to say that was pretty impressive," she said.

"Come here, Sam," Tanya said.

The sound of her voice sent another surge of blood into my cock, which went back to full attention. When I got closer Tanya reached over and took hold of my cock. My knees almost buckled.

"Ooh, nice," Tanya said, laughing. "I might have a hard time choosing between them."

Vickie elbowed her in the ribs. They seemed to be good friends all of a sudden.

"You guys make yourselves decent," Tanya said. "We still gotta get into the room somehow."

"I think we can slip through the bushes at the back," Nick said.

"We still need to get into the room to get that joint," Tanya said.

"We'll figure it out," Nick answered, and off they went, arm in arm again.

Vickie and I walked several paces behind.

"Are you ok with this?" I asked under my breath.

"Um, well, yes, I think so," she said. "Are you?"

"Totally."

She giggled again.

"I think they're hoping we'll swap," I said.

She stopped.

"Really?" she asked. "I don't know...."

"You've already felt Nick's cock," I teased.

"Well, I wasn't planning to do that," she said. "Tanya caught me off guard. How do you feel about it?"

"I'm open for anything at this point."

We walked quietly for a minute or so. She seemed to be thinking.

"Ok," she finally said, then gave me a passionate kiss. "Let's go and see what happens."
