The swap began in a deserted cove

As I mentioned on another occasion, my name is Marcos, I’m thirty-five years old, and I’ve been living with my girlfriend for a long time. This story has a real part and a fantasy part, but I still struggle to separate the two when I remember it.

Daniela and I weren’t going through our best moment. Work, routine, arguments over the smallest thing. We’d been together too many years to throw everything away without trying something first, so we decided to get away for a few days, just the two of us, to a little coastal town. It was spring, but the heat had come early and it felt like the middle of summer.

We found a small hotel, with barely ten rooms, on the outskirts of a seaside town and a ten-minute walk from the beach. Far from the crowds, perfect for unwinding. Daniela packed a suitcase with bikinis and comfortable clothes; the mood we had as a couple didn’t call for much more.

My girlfriend is thirty, dark-haired, petite, with small breasts. Despite everything we were going through, to me she was still a very attractive woman. We arrived on Thursday late in the morning, checked in, and went down to the town for lunch. The afternoon passed like any beach afternoon: sun, water, long silences. We were relaxed, but the distance between us was still there.

That night the hotel offered dinner in its small restaurant. Daniela got dressed up and chose a black dress with an open back, no bra, and I put on a dark shirt. She looked spectacular with the tan she’d picked up that afternoon, and I wasn’t the only one who noticed.

When I went up to the room to drop off the bag, she waited for me in reception. When I came back down I found her chatting with another couple, quite a bit older than us, around fifty-something. He was very well preserved, gray-haired and in good shape; she was elegant, perfumed, one of those women who age better than most at twenty.

“Look, darling, let me introduce you to Renata and Esteban,” Daniela said. “They’re staying here too.”

I gave Renata two kisses and shook Esteban’s hand.

“Nice to meet you, I’m Marcos.”

“They told us there’s a bar behind the hotel with good music,” Daniela went on. “They were there last night and they’re going back today. They invited us. What do you think?”

Spending the first night of our getaway with two strangers wasn’t my plan, but Daniela wasn’t too thrilled about spending the evening alone with me either. We accepted.

The women left the hotel ahead of us, chatting as if they’d known each other all their lives. Esteban and I walked behind them talking about unimportant things. The bar was quiet, with a couple of tables occupied and nothing else. They settled into some sofas at the back while we ordered drinks at the counter.

When we came back, Esteban sat down next to Daniela without hesitation, with a brazen ease that left me thrown. I didn’t make a big deal of it, set the drinks down, and sat next to Renata. The night was pleasant, more than I’d expected. They seemed like a completely normal couple, fun, easy to talk to. After two hours and several drinks, we decided to go back to the hotel.

On the way back, Renata mentioned that the next day they were going to some hidden coves they’d been recommended, and invited us to join them. Daniela said yes before I even opened my mouth. We arranged to have breakfast at eight-thirty.

That night, Daniela and I fucked like we hadn’t in months. I don’t know if it was the alcohol, the change of scenery, or something I still didn’t understand, but it was incredible. I fell asleep thinking the getaway was starting to work.

The next morning, Esteban and Renata were already in the café, right on time. We arrived late: me lounging around in bed and Daniela dithering over which bikini to wear. She chose a white thong bikini, much bolder than the one from the day before. Esteban offered to drive us in his SUV, more comfortable for getting to the coves, and we agreed.

After forty minutes on the road, we parked beside a small wood. We walked ten minutes along a path that in high season must have been full and that on that Friday morning was completely empty. At the end of the path a small cove appeared, surrounded by trees and rocks, with not a soul in sight.

“I told you it was worth it,” Esteban said, smiling.

We walked to a secluded side and spread out the towels. Daniela took off her dress and stayed in her bikini, and I noticed Esteban blatantly checking her out. Renata, for her part, wore a tiny red bikini that showed off her well-kept body. I returned the look he’d given my girlfriend.

“The view is stunning, and I’m not talking about the scenery,” Esteban said with a laugh.

Far from bothering me, that comment got me thinking. My relationship with Daniela was going downhill, and suddenly I saw her flirting, laughing, loosening up in a way she hadn’t with me for a long time. A mix of jealousy and arousal began to grow inside me.

We sat down to slather ourselves in sunscreen. Esteban took the lead, breaking every awkward silence.

“Renata, take your top off,” he said. “These guys aren’t going to freak out.”

She unclasped her bra without answering and started rubbing sunscreen over her breasts, which, freed, seemed even bigger. She didn’t have a single tan line; it was obvious she went topless often.

“I hope you don’t mind,” she said, turning toward us.

“Not at all, I do it too,” Daniela replied, and she took off her bikini top, leaving her breasts bare.

I looked at her without daring to say anything. It was the first time she’d gone topless in front of other people. Esteban couldn’t take his eyes off her, and Daniela lay down on her back as if nothing were happening.

***

Renata got up to go for a swim and Esteban went with her, leaving us alone for a moment.

“Have you seen the way he looks at you?” I said to Daniela.

“The same way you look at her,” she shot back, a little annoyed. “They’re strangers, we’re not going to see them again. And look at the beach: there’s nobody here. Don’t be such a pain.”

She stood up and walked toward the water, spectacular, with the white thong contrasting against her tanned skin. I didn’t feel like getting wet, but something told me I shouldn’t leave them alone, so I followed her and held her from behind as we went into the water.

Inside, the atmosphere couldn’t have been better. We chatted, laughed at Esteban’s jokes; despite his age, he had a cheerful way about him. He started with games: splashing, pushing, trying to dunk Renata and, every now and then, Daniela too. Little by little the games turned into more touching, more hands. Renata played along and Daniela, far from pulling away, seemed to enjoy it. I stayed on the sidelines, as if I didn’t belong to that group that understood one another without words.

“Marcos, don’t just stand there,” Renata said, coming over to splash me.

The fact that it was her, and not my girlfriend, who encouraged me to join in, scrambled my head. I decided to let myself go.

Meanwhile, Esteban was grabbing Daniela by the waist to tip her into the water. Renata climbed onto my back, pressing her breasts against me, and dunked me suddenly. When I came up, I saw Esteban’s hands on my girlfriend’s ass, pushing her under the water. Daniela clutched at her swimsuit bottom to keep from going under and pulled hard.

“You brute!” she said, coming up laughing. “I swallowed loads of water.”

I had seen Esteban’s hands on her ass, on purpose, without a doubt. And what shook me most was that Daniela hadn’t done anything to get them off.

***

We got out to sunbathe and crack open the beers we’d brought. Esteban stayed in the water a little longer and after a while came out slowly, holding his swimsuit with his hand.

“Guys, I’ve got a problem,” he said, laughing. “I think Daniela has torn my swimsuit by grabbing on. It falls down if I don’t hold it.”

“What do you mean?” Daniela stood up worried and went to check. “Shit, sorry, what a clumsy idiot I am.”

“No, honestly, these things happen. I thought I’d just take it off, if you don’t mind. Renata and I have gone nude before.”

I looked at Daniela, then at him. I thought that would be the end of it, that my girlfriend, always so modest, wouldn’t want some naked guy beside us all day.

“No problem on our side,” she said with a smile. “I tore it, I’m not going to make you leave.”

The three of them waited for my answer. What was I going to do, get up and leave? Not even the car was mine.

“Go ahead. It’s not like we’re going to see anything we haven’t seen before,” I said, trying to sound funny.

Before I even finished the sentence, Esteban let go of the swimsuit and it fell into the sand, leaving his dick exposed in front of his wife and my girlfriend, both of whom couldn’t take their eyes off it.

“Wow, well, that’s...” Daniela began, and bit her tongue. “He did say it had torn.”

He had a good body. His cock was slimmer than mine but quite a bit longer, even at rest. We all lay down in silence, with only the sea and the seagulls to be heard.

After a while, Renata came back from the water, took off her bikini bottoms and stayed completely naked.

“You don’t mind, do you? I’m more comfortable, and since Esteban is the same...”

“Not at all, darling,” Daniela said, glancing at me from the corner of her eye.

My girlfriend got up to go for a swim and I took the chance to go in with her. In the water, alone again, I asked her what she thought of all this.

“I think we’ve let it get out of hand,” she said. “But we can’t back out now. We’re not going to see them again and there’s nobody here. I’m going to loosen up, I’m going to do the same as Renata.”

“Are you crazy? You’re embarrassed even when I see you naked.”

“I’m not going to be the one, the younger one, who looks like an old woman,” she told me, half-joking, half-serious. “Besides, you’ve been eyeing Renata up for a while now. Maybe it’s time Esteban looks at me.”

I came out after her, wanting to stop her from crossing that line, because I knew that once it was crossed there’d be no turning back. It was impossible.

When we reached the towels, Daniela took off her thong in front of both of them.

“It’s only fair that I join in too, right?” she said, completely naked.

“Oh, wow,” Esteban murmured, not even pretending otherwise.

I was walking up from the sea, taking in the scene: my girlfriend naked in front of two strangers, with the slightest hint of shame.

“Darling, you’re shyer, but you should join in,” she said to me with irony.

“No problem,” I answered, and slid my swimsuit down, my cock already half hard.

It was the first time we’d been naked in front of other people. The mix of arousal, excitement and anger at the way Daniela was acting made my cock grow little by little. We had completely lost control.

“In the end it was good that you tore my swimsuit,” said Esteban.

“So you can see us naked, huh?” she replied, stroking his back.

“You don’t see a thirty-year-old body like that every day.”

“Silly man. Though what I’m seeing isn’t bad at all either,” Daniela said, looking at the cock hanging from him.

“Well, Marcos, what do we do with these two? Look at the way they’re looking at each other,” Renata said to me, coming closer.

“They are being very nosey, yes,” I answered, swallowing my pride.

“Then what you’re looking at must be what you like,” Esteban shot back, pointing at my cock, hard and stiff.

“Maybe he can’t get hard because he hasn’t found someone who knows how to do it?” Daniela said, surprising me with her audacity.

“Want to try?” he replied.

There was a silence that felt endless to me. My sweet girlfriend had just challenged a man we’d met the night before, and he had accepted.

***

I moved back to the towel and Renata sat down beside me. Daniela gathered her hair into a ponytail, looked at us, smiled, and reached out her hand toward Esteban’s cock. She caressed it, stroked it, but it stayed soft.

“I told you it wouldn’t be that easy, darling,” Renata laughed.

I hadn’t finished the sentence when Daniela took all of it into her mouth. She looked delighted, and it had been a long time since she’d sucked me like that.

“Fuck, what a mouth,” Esteban groaned, grabbing her by the head.

That scene sent me through the roof. I was watching my girlfriend suck another man’s cock in front of me, and I was loving it. I started touching myself. Renata noticed, stretched out her hand, and began to masturbate me while keeping her eyes on her husband and Daniela.

I stroked her breasts, those big pink nipples, while she moved my cock faster and faster. Across from us, Daniela was still on her knees, mouth full, and Esteban’s cock kept growing and growing.

I was about to come. Renata noticed from the spasms and bent down to take me into her mouth. While Daniela sucked one man, his wife swallowed mine.

“Ah, fuck, I’m going, I’m going,” I managed to shout, unloading in her mouth.

Hearing me, Daniela sped up the rhythm, grabbed Esteban by the ass, and pushed him toward her. Then she pulled away, turned, and looked at us.

“Maybe you needed someone who knew how to handle this, darling,” she said, still breathing hard.

“That tongue of yours is too much,” Esteban replied, helping her up as they kissed.

And that’s how a weekend began in which I accepted and enjoyed, for the first time, partner swapping, watching my girlfriend enjoy herself like never before. But that’s another story.
