What Happened When We Swapped Partners for the First Time

We’re Martín and Lucía, and for some time we’d been turning over the idea of opening ourselves up to other couples. It wasn’t something we decided from one day to the next. It was months of quiet conversations, of fantasizing in bed after fucking, of imagining out loud what we would feel seeing the other with someone else, with another cock inside them, with another cunt riding on top of us.

Through a well-known dating site, we came across Diego and Sabrina, who lived in the same city as us. They were just as eager as we were to try the swapping lifestyle, although until then they had only shared threesomes with other women. They were beginners at this, just like us, and that shared awkwardness made us trust them.

As usually happens, we talked for weeks first. Messages that stretched into the early hours, video calls where we studied each other’s faces, laughed at any old nonsense, and little by little dared to talk openly about sex—how we fucked, what we liked sucking, how long we could last before coming. We wanted to make sure there was chemistry before meeting in person.

One day we invited them over. Our children were with their grandparents, so we had the whole afternoon to ourselves. The agreement was clear: just get acquainted, have a drink, and see whether what we felt through the screen still existed in person. No sex. The date was only to test the waters.

They arrived on time. Diego was tall and dark-haired, one of those men who takes care with every detail and knows it. Sabrina, on the other hand, was short, generously curved, with enormous breasts and a smile that always seemed about to unleash some mischief. It was enough to see them in the entryway to confirm that the attraction hadn’t been a camera-induced illusion.

I made coffee and we sat in the living room, two couples facing each other, talking as if we’d known one another all our lives. The conversation flowed on its own, dotted with laughter and those looks that last a second too long.

—We brought you something from the bakery downstairs —Sabrina said, setting a box on the table—. I didn’t know whether you preferred sweet or savory.

—Everything. We like everything —Lucía replied, and all four of us laughed at the double meaning no one had intended but everyone understood.

We talked about how we’d ended up there, the nerves of the first video call, the doubts we’d had, and the desire that had won out. Diego talked with his hands, gesturing, and Sabrina interrupted him every couple of minutes with some correction that ended in laughter. It was easy being with them. Perhaps too easy for an afternoon that was supposed to be innocent.

At one point in the conversation, Diego mentioned that he’d just gotten a new car, a model he’d been waiting months for. With practiced casualness, he suggested that Lucía go downstairs with him so he could show it to her and take her around the block.

—Shall we? —he asked her, already standing.

Lucía looked at me, a silent question passing between us. I gave her an almost imperceptible nod. Go ahead. I knew perfectly well that the walk was an excuse. And I suspected she knew it too.

I was left alone with Sabrina in the living room. The silence that remained after they closed the door carried a different weight, charged with everything we hadn’t said over coffee.

—So, we’re alone —she murmured, setting her cup on the table without taking her eyes off me.

I didn’t have to answer. She came closer, sat down very near me, and kissed me. At first it was a slow, tentative kiss, and then it quickly became hungry. She bit my lip, pushed her tongue deep into my mouth, and while she devoured me she already had one hand slipping beneath my sweatpants, searching for my cock, squeezing it through my underwear with a boldness that drew a moan from me.

—You’re already rock-hard —she whispered against my ear, pulling me out and beginning to jerk me slowly, closing her fist around the head and sliding down to the base—. I spent the whole afternoon imagining what you’d be like.

I stopped her for a moment, not to slow her down but to look at her. Her cheeks were flushed and her breathing quick, yet she kept stroking my cock with a slowness that was driving me insane. Then I was the one who took the initiative. I yanked her blouse over her head, ripped open her bra, and revealed the breasts I’d tried not to stare at all afternoon, her enormous tits hanging free, her pink, hard nipples begging for a mouth.

I lunged at them as if I hadn’t eaten in weeks. I sucked one nipple, bit it without mercy, tugged it with my teeth until she moaned, then moved to the other and did the same while squeezing both tits in my hands, pressing them together, crushing them against her face. Sabrina threw her head back, bit her lip to keep from screaming, and rubbed herself against my thigh, seeking friction for her cunt.

—Pull my pants down, you bastard —she panted—. Pull them down now.

I ripped off her leggings and yanked off her panties too; they were soaked from top to bottom. I spread her legs wide on the sofa and stared at her open cunt, glistening and swollen, her lips showing and her clitoris already peeking out from beneath its hood. I knelt on the rug, held her thighs with both hands, and attacked her with my mouth.

I ran my whole tongue from bottom to top, from her entrance to her clitoris, and felt her jerk. I did it again, more slowly, savoring every bit of her taste, then closed my lips around her clitoris and began sucking it rhythmically, giving her no respite. Sabrina grabbed my hair with both hands and began fucking my mouth with thrusts of her hips.

—Put it inside me, put it inside me with your tongue, you son of a bitch —she begged through clenched teeth.

I plunged my tongue inside her cunt as deeply as I could while rubbing her clitoris in quick circles with my thumb. Her legs tensed, she clamped her thighs around my head, and she came within seconds, biting the back of her hand to keep from making too much noise, soaking my entire face with her juices.

—I’d been thinking about this all afternoon —she confessed in my ear when I lifted her back up to my level, still breathing hard, her eyes glassy—. Ever since you opened the door. Eat up everything I give you.

I didn’t tell her I felt the same way. There was no need. I’d read it in every gesture since the first coffee. She dropped to her knees between my legs, pulled my pants and underwear down to my ankles, and swallowed my cock in one sitting, all the way to the base, until her nose bumped against my stomach. I felt her throat tighten around my head and let out a growl that escaped from my chest.

She started sucking me as if her life depended on it. Her mouth traveled up and down, taking me all the way in, strings of saliva slipping from her chin, and whenever she pulled my cock out she used it to slap her tongue and tits before taking it back in. She looked up at me, eyes watering and mouth open, enjoying every inch. I grabbed her head with both hands and began fucking her throat at an increasingly brutal pace, feeling her choke and yet never stop.

—I’m going to come —I warned her—. I’m going to come in your fucking mouth.

She nodded with my cock inside her and squeezed tighter, sucking hard, and I emptied myself into her mouth in spurts. She swallowed it all without losing a drop, and when she was done she pulled my dick out with a wet kiss on the tip and smiled at me, her lips shining.

We stayed still for a while, catching our breath, quietly laughing at how little our promise to “just get acquainted” had lasted. We straightened our clothes just in time and settled onto the sofa, pretending to be calm when we weren’t.

Lucía and Diego came back soon afterward, both wearing ear-to-ear smiles that gave them away. As soon as they left, my wife told me everything.

***

She told me Diego had parked on a quiet street, away from prying eyes. That he kissed her first, slowly, and then slipped a hand beneath her leggings, surprised to find no panties in the way. That he pushed two fingers into her cunt and worked them inside until she was trembling, his palm smacking her clitoris with every thrust, and she came while biting his neck. In response, she unbuttoned his pants, pulled out his cock—big and thick, with prominent veins—and sucked him right there in the driver’s seat until he filled her mouth with his cum, which she swallowed without hesitation. Nothing more. A preview, a map of what was to come.

That night in bed, we couldn’t stop talking about them while fucking as if it were our first time. The conclusion came naturally: the four of us liked each other, and we wanted more. We made plans for the following Saturday. This time with no excuses, no coffee in between, no brakes.

The week dragged on forever. Each passing day tightened the cord a little more. Lucía gave me little looks over dinner, I answered with some raunchy comment, and we both went to bed with our minds fixed on Saturday.

At last they arrived, this time with a bottle of white wine to go with dinner. We sat at the table with the couples crossed, each of us facing someone who wasn’t our partner. The tension could be cut with a knife.

It didn’t take much. Beneath the tablecloth, our feet began misbehaving. A toe brushing a thigh, a heel traveling up a leg, stolen caresses while we maintained a surface conversation that no one cared about anymore. I had my bare foot between Sabrina’s thighs and could feel through the thin fabric how soaked she already was. The atmosphere was hot long before we finished dinner.

When the moment came, things didn’t go like they do in swinging movies. Diego confessed, half shy and half proud, that he’d rather not see Sabrina with someone else. It was a strange mixture of arousal and jealousy that he still hadn’t fully mastered. No one made an issue of it. We split up: they went to one bedroom, and we went to the other.

I took Sabrina. Lucía went with Diego.

Sabrina was pure energy. I laid her on the bed, tore her dress over her head, and found her already without underwear, prepared and knowing exactly what was going to happen. I spread her legs wide, placed them over my shoulders, and lowered myself between them, ready to repay her for the first afternoon many times over. I began eating her cunt slowly, with long licks, sucking her lips one by one, nibbling her clitoris with my lips, and she responded like a storm.

I slid two fingers inside her and searched for the spot inside, the one that makes the walls swell when you find it. She came after a few minutes, soaking my chin and squeezing my head between her thighs. I gave her no respite. I kept sucking her hypersensitive clitoris while moving my fingers inside her, faster and deeper, and she came again two minutes later, arching her back and slapping at the sheets. And once more, with three fingers inside her and my tongue vibrating against her clitoris, while she screamed into the pillow.

—Enough, enough —she panted—. I can’t take any more. I need you inside me now. Fuck me now, please.

I climbed on top of her with my cock ready to burst. When I reached for a condom, she stopped me with a gesture, catching my wrist.

—No —she said, staring straight at me—. I’ve never been with anyone but Diego. I want to feel you for real, with nothing between us. I want to feel you come inside me.

It wasn’t our usual practice, but the way she asked left no room for doubt. I rubbed my glans up and down her lips, ran it over her clitoris until she began begging through clenched teeth, and then I drove into her in a single thrust, all the way to the bottom, skin against skin, and the sensation drew a moan from both of us at the same time. The raw tightness of her cunt, without rubber between us, squeezing every inch of my cock, almost made me come on the first stroke.

I stayed still inside her for a moment, feeling her pulse around me, then began moving slowly, pulling almost all the way out and pushing back in to the hilt. She dug her nails into my back and whispered filthy things in my ear.

—Harder, deeper, break me, you bastard, just like that, don’t stop.

I did as she asked. I grabbed her by the waist and began pounding her with everything I had, hearing the wet slap of our bodies, my balls striking her ass, her muffled cries against my shoulder. I bit one nipple while fucking her, pinched the other, and she came for the fourth time that night, squeezing my cock inside her with spasms that dragged me along with her. I finished inside her without holding back, emptying every last drop, feeling my semen mix with her juices and begin running between her thighs.

I thought we were done, that she was exhausted. I was wrong. Sabrina turned over, got on all fours, and, looking at me over her shoulder with her ass raised high and her cunt dripping my cum, asked me for what was left.

—Now here —she said, pulling one cheek aside and showing me her asshole—. Put it up my ass. With all your cum still inside me. I want to feel you in both holes.

We needed no lubricant beyond her own wetness mixed with my cum. I gathered what was dripping from her cunt with two fingers, spread it over her asshole, and slowly pushed them inside to prepare her; it was obvious this wasn’t the first time she’d enjoyed herself this way. She opened up without resistance. I pressed my glans against her asshole and pushed, and the ring gave way, squeezing me like a fist.

—Fuck —she moaned—. Fuck, you’re so thick. Give me all of it.

I eased it in little by little, inch by inch, until I was buried to the balls. Her ass squeezed so tightly I could feel the pulse of blood in my cock. I held her by the hips and began moving, gently at first and then more brutally, while she brought one hand to her cunt and masturbated at the same time, rubbing her clitoris in quick circles.

—Fuck my ass, yes, harder, give it to me like that, don’t stop —she begged between gasps, her face buried in the pillow and her ass raised to receive every thrust.

I smacked her buttock, leaving the print of my hand, then did it again, and again. I grabbed her hair, pulled her head back, and fucked her ass with all the strength I had left, hearing the hard smack of my pelvis against her buttocks. She came again while fingering her cunt, and her asshole tightened so intensely that it made me explode for the second time, emptying the rest of my cum into her ass, every last drop.

We collapsed exhausted onto the bed, sweaty and breathless, my cock still inside her, my cum beginning to leak from both holes. We fell asleep wrapped in each other’s arms, as if we’d been doing it for years.

Lucía told me her part of the night afterward. As soon as she entered the room with Diego, he threw her onto the bed, ripped off her panties, and buried himself between her legs until he gave her one of those orgasms that leave you trembling, eating her cunt with a technique that left her speechless. She returned the favor with her mouth, sucking his entire cock while playing with his balls at the same time, until he couldn’t take any more and asked her to move on to the next thing. He fucked her on her back, her legs over his shoulders, and while he took her at a brutal pace, his cock going all the way in each time, he whispered that she should rub her clitoris, which made her come for the second time in a very short while, screaming in his face. Then he put her astride him and made her ride him, and she came again while riding him, feeling him explode inside her. They spent almost the entire night giving themselves to each other, fucking in every position they could think of, just as we did on the other side of the hall.

The next morning, the four of us had breakfast together, sharing the new complicity of people who have crossed a line and don’t regret it. And far from ending there, things continued well into the day. They stayed at our house for the whole weekend, and amid laughter, wine, and tangled sheets, we lost count of how many times we started all over again.

Sabrina was incredible, a woman made for pleasure, capable of coming five or six times in a row without a break and still asking for more cock. Diego was too, with that thick dick Lucía loved having inside her, although he always had that strange hang-up about not wanting the four of us together in the same bed. His reserve took some of the thrill out of it, but even so, we continued enjoying ourselves for quite some time.

What we had with them lasted until Diego was transferred to another city for work. Even so, we visited them once in their new home, and the story had a final chapter as intense as the first.

Of all the things Lucía and I have dared to try together, that was without a doubt one of the kinkiest. And the one that showed us that opening the door is sometimes only the beginning.
