The Swap with the Young Couple from the Gym

I don’t know if being called “little mature man” by a girl barely in her twenties counts as a compliment, but I decided a long time ago to take it that way. At my age, a young smile aimed at you is worth more than any sincere compliment.

It all started with something silly at the gym I go to, whenever work allows, three or four days a week. Sometimes alone, sometimes with Marina, my wife.

There we often crossed paths with a couple quite a bit younger than us, and over time we’d become friendly. Marina and Nadia would go to the sauna together after training, and they’d even met up a few times for coffee. For my part, I got along well with Bruno, her boyfriend, and we’d usually go for a run before the weights.

Bruno was my height, slim, dark-haired, with an easy smile and quite talkative. Nadia, on the other hand, barely reached five feet; petite, with straight pageboy-cut hair and huge brown eyes that seemed to say everything even though she almost never opened her mouth. She had a slender body, with small, round breasts and a perky ass. She wasn’t a magazine beauty, but she had a look and a smile that stayed with you.

One afternoon Bruno and I went out for a run while they stayed inside. When we came back, they weren’t in the room anymore, so we assumed they’d gone into the sauna. We finished our routines and, as we walked into the locker room, we ran into them coming out of theirs, already showered and dressed.

“We’ll wait for you at the bar across the street,” said Nadia, almost in a whisper.

At that gym the showers are individual, but that afternoon there was only one free. Rather than waste time, we both went in.

“You mind? That way we won’t take long. And no fairy stuff, okay?” Bruno joked.

“Too bad, I was already getting my hopes up,” I answered, and we laughed.

Under the water I couldn’t help stealing a few sideways glances. Something natural between two men showering together, I told myself. Lean runner’s body, strong legs, firm ass. And when I saw his cock, what I saw didn’t bother me: not too long, but thick, with a hefty pink glans. I realized he was looking at me too, so I didn’t bother covering myself; I turned a little so he could get a good look.

When we came out, the girls already had beers waiting on the terrace.

“What a beating we gave ourselves today,” Bruno said, dropping into the chair.

“Then no sex tonight,” Nadia laughed, blushing instantly at her own boldness.

“No way. I always have enough energy for that,” he replied.

She looked at him with those huge eyes and lowered her gaze. We chatted a while longer and said goodbye.

On the way home, Marina wouldn’t stop talking about them.

“Such a nice couple. And so different, right? He never shuts up and she barely speaks.”

“Here we go,” I said, knowing her well.

“What? I didn’t say anything. Just that she has such a cute little body…” she laughed, and I laughed with her.

That night, after dinner, her hand found me in bed. She stroked me slowly until I was hard, moving her fist up and down without rushing. I didn’t complain. I took my hand to her sex and found it already soaked.

She turned her face toward me and we kissed without stopping touching each other, until she straddled me and sat on my cock very slowly. I could feel the heat of her inside as she rose, leaving only the glans in, then lowered herself all the way down again. Her hard nipples dug into my chest and she panted against my mouth.

I lifted my hips to get in deeper and, turning her, ended up on top of her, her legs wrapped around me. I fucked her like that until she came trembling, and a little later I emptied myself inside her while I felt her pulsing around me.

“That was so good,” she murmured before falling asleep curled up against me.

And she still had no idea what was about to hit us.

A couple of quiet weeks went by. Until one day we noticed Bruno was showing up at the gym alone, and much less talkative than usual.

“And Nadia?” Marina asked.

“Mad at me. She doesn’t want to come,” he replied, avoiding my gaze.

“You haven’t cheated on her, have you?” she joked.

“No, no... But I think I really fucked up.”

We left it at that. The next day I went alone and, when I finished, I took him out for a beer. It didn’t take long for him to open up.

“I got the idea of telling her a fantasy while we were at it,” he said, staring at the foam in his glass. “I suggested a threesome with another woman.”

“Oof. Not your finest timing,” I replied.

“There’s more. Don’t take this the wrong way, but... I dropped your wife’s name.”

I looked at him half smiling.

“Relax, I’m not taking it the wrong way. I know exactly what Marina is like and how men look at her.”

“It’s just that they’re so different... I get turned on seeing two women, imagining Nadia and another one.”

“And have you watched any movie with two men and a woman?” I asked, testing the waters.

“Yeah. That doesn’t do as much for me.”

“And for her?”

“I don’t know, honestly.”

“Well, then get it into your head that if you want to ask for something, you have to be willing to give on something else.”

***

Two days later Nadia came back to the gym. As quiet as ever, but avoiding my gaze in a new way. While we were training, Bruno told me we should talk later, that she’d left him rattled.

He told me in the bar.

“She said yes. But with conditions,” he began. “She has a fantasy too, and she wants to fulfill it first. She says she’d like to be with an older man. And since I brought up your wife, with me... I mean, with you, she wouldn’t mind.”

I took a long swallow of my beer.

“I’ll take ‘older’ as a compliment,” I said.

Bruno was still looking down, so I told him something I hadn’t told anyone at the gym in years: that Marina and I were an open couple, that swapping partners was nothing new to us. His jaw dropped.

“That’s insane. I don’t know if I could go that far.”

“Don’t worry. Talk about it, give yourselves time. And if in the end it’s a no, no big deal.”

At that moment the girls arrived. Nadia, who was already a woman of few words, barely opened her mouth that afternoon.

On the way home, Marina told me her version: Nadia had told her everything in the sauna.

“And what do you think?” I asked her.

“I find him attractive. And her too. What’s funny is I thought it would be the other way around, that she’d be the one hesitating.”

***

On Friday they invited us to dinner at their place. No one had to work the next day, so there were no excuses.

That afternoon Marina got ready properly: she waxed, rubbed cream all over her body, and chose a black lace set that barely contained her breasts. Watching her walk naked around the house knowing what she was dressing for had me hard most of the afternoon.

They lived ten minutes away on foot, in a small apartment with slanted ceilings but very nicely put together. We brought wine. Bruno opened the door for us; Nadia came out of the bedroom when she heard us and kissed us both on the cheek with a shyness that was almost sweet.

During dinner they both seemed nervous, but we talked about everything and nothing. It wasn’t until dessert, when some of Nadia’s spilled, that the real subject came up.

“Sorry, I’m a little nervous,” she said, red as a tomato.

“It’s okay,” Marina reassured her, taking charge. “I suppose you’ve talked about it.”

“Yes. Bruno told me you two had already done swaps.”

“Just so we’re clear, nothing has to happen,” I interjected. “We can talk about it and that’s all.”

But Bruno’s eyes were already shining, and he couldn’t take his gaze off my wife’s breasts. Nadia, on the other hand, was still flustered, and seeing her so shy was turning me on more and more.

“If I may give you a piece of advice,” I said, “you both need to be clear on it. And if you feel like it, you don’t even have to watch each other while it happens.”

“I’m not clear at all about my side,” Nadia confessed. “But I admit knowing Bruno is going to be with another woman has me somewhere between excited and jealous.”

“I feel something similar,” he said. “But we want to try.”

That innocent air about the two of them was heating Marina and me up more than they imagined. My wife stood up, took them by the hands, and led them to the sofa. I sat across from them, in the armchair, saying nothing.

“Why don’t you start, nice and slow? A few kisses, some caresses...” Marina suggested.

Shyly, they kissed while glancing sideways at us. The first hand was Bruno’s, stroking one of her breasts over her clothes; she responded right away, reaching for his crotch. When he slipped his hand under her sweater, Nadia let out a sigh and started holding her breath each time he pinched a nipple.

Watching them like that had my cock pressing hard against my pants. I moved closer and sat beside Marina. I copied Bruno: my hands went to my wife’s breasts, feeling her nipples harden under her bra, while she reached for my erection.

I stood up, lifted her, and took off her blouse and jeans. Nadia glanced at us out of the corner of her eye and, without saying anything, let Bruno undress her too. Soon all four of us were naked, two couples looking at each other in the same living room, touching as our breathing grew louder and louder.

That was when Marina made the move. She took Bruno by the hand and led him toward the bedroom, leaving Nadia and me alone.

There she was, standing in front of me, completely naked except for her glasses, undecided. Very pale skin, small breasts that fit in the palm of a hand, pink nipples already hard. Fine, neatly trimmed hair framed thin lips.

I made no move. I wanted her to be the one to decide. She came closer slowly, breathing hard, not looking me in the face, until she rested my glans against her belly. She lifted her hand and wrapped her fingers around me, sliding them down toward the base, and a shiver ran through my whole body.

She lowered her head, stuck out the tip of her tongue, and licked one nipple before trapping it between her lips. I held out for a moment; then I scooped her up and carried her to the sofa.

I laid her down and positioned myself over her, looking for her mouth. She responded hungrily, slipping her tongue into mine. I took one breast fully in my hand, feeling the hard nipple against my palm, while her body trembled beneath mine.

“Do you want to keep going, or would you rather I stop?” I asked, leaning on my elbows.

She opened those huge eyes and only one muffled word came out of her lips.

“Keep going.”

I worked my way down. I kissed her neck, her breasts, her firm belly, until I found her sex in front of my face. I kissed her thighs before placing my lips between her legs. She let out a gasp and lifted her hips. I licked her slowly, parting her lips to get deeper, until I found the clit, already swollen.

The moment I touched it with my tongue, she buried her fingers in my hair and pressed my head against her. I stretched my arms to reach her breasts without stopping moving my tongue. It hadn’t even been a minute: in spasms, she had her first orgasm of the night.

She pulled me up and kissed me, not caring that my face was soaked. Her head turned toward the bedroom door, from which moans were coming.

“Do you want to watch?” I asked her.

She nodded, smiling. I took her by the hand and we went to peek.

***

I never took my eyes off her face while she watched the scene. Marina was on her knees on the bed and Bruno was pounding her from behind, gripping her hips and making her breasts sway. From the doorway you could clearly see how his thick cock went in and out with force. Both of them were panting, their bodies moving in unison.

Nadia stood watching them, and I stood behind her. A moment later she passed her hand between our bodies, grabbed my cock, and took one of my hands to her sex. She was soaked. While my fingers played inside her, she pressed her body against mine and moved her hips as if I were inside her, feeling my glans slide between her cheeks.

She didn’t take long to turn around and drag me by the hand to the sofa. I sat down, she knelt between my legs, and lowered her head. The first thing I felt was her warm breath on the glans, and then the wetness of her tongue circling it. Electricity shot up my back.

She ran her tongue right where the glans meets the shaft before taking me all the way into her mouth, moving her head up and down, one hand softly squeezing my balls. She stopped for a second to take off her glasses and set them aside.

“At this rate I’m not going to last long,” I warned her.

She sat up, rolled a condom on me, and sat down on top, guiding me herself all the way into the depths of her hot, tight sex. She did it with her eyes closed, holding her breath. Once she had me inside, she started moving slowly, moistening her lips with her tongue.

With her breasts at my face level, I kissed them, trapping the nipples between my lips. She murmured things I couldn’t make out while she rode me faster and faster. Her insides gripped me with every movement, rising until only the glans remained in, then lowering all the way down again.

She leaned back and then collapsed onto me, kissing my neck without stopping her motion.

“Yes, yes... I’m going to cum again,” she panted.

I felt her shaking as she reached orgasm, but she didn’t stop until she felt me convulsing too with moans. She stayed lying on top of me, breasts crushed against my chest, catching her breath.

When I rolled to her side, she spread her legs, showing me her shining sex without a trace of the earlier embarrassment.

***

For a matter of seconds, Bruno missed the sight of his girlfriend riding me: just then he and Marina appeared, both completely naked. My wife sat down beside me and kissed me; the guys looked at each other, not knowing what to say, until Nadia gestured for Bruno to sit next to her and rested her head on his thigh.

For a moment all you could hear were four ragged breaths. It was Marina who broke the silence.

“So? Everything okay?”

“I’m fantastic,” I said.

“I’m great,” Nadia replied, and those were the first words that had come easily from her since dinner. “And you?”

“Me too. Very good,” Bruno murmured.

“Well then, you’ve both popped your cherries,” Marina smiled. “Was it really that hard?”

“When we came to peek at you... I thought I’d get jealous, but it turned me on even more,” Nadia confessed.

“You saw us?” he asked.

She nodded, laughing for the first time all night.

“Yes. And you were not having a bad time at all.”

This time it was Bruno who blushed. We kept talking a while longer, until Nadia’s hand started stroking his cock again, and it didn’t take long for it to harden once more.

“Since we’re at it...” she said, looking at the four of us, “we could keep going a little longer.”
