What I Saw in the Gym Sauna That Afternoon

I don’t know whether it was because the small gym I’d set up in my garage was no longer enough for me, or because winter gave me strange urges to get out and brush up against people. The fact is, one morning on my way to work, I slowed down in front of that strikingly designed building and decided I’d had enough of training alone between four walls.

It was called VitalArena and was an eight-minute walk from home. When I went in to ask about it, the trainer showed me around the facilities like someone presenting a luxury apartment: enormous windows, pale-blue and mint-green walls, a spinning room, another for instructor-led classes, a weight-training area that smelled of new rubber, and, at the back, one detail that finally convinced me.

“And this here,” he said, opening a frosted-glass door, “is the spa area. Sauna, cold baths, massages. We include three months with the sign-up promotion.”

It was a secluded area, almost hidden behind the locker rooms. Two corridors, one for men and one for women, opened into the same steamy room where the temperature rose suddenly. Hardly anyone used it. I liked that. I signed up that very day.

The first few weeks were exactly what I’d been looking for. A clean gym, good music, a lively atmosphere. I’d even made a couple of acquaintances in the weight room with whom I could talk about football, routines, and, it has to be said, the people who passed by. There was no shortage of variety. Everyone had something to look at, and most of them took care of their bodies in a way that made you envious. Round, tight asses squeezed into impossible leggings, big tits bouncing on the treadmills, muscular guys with their cocks outlined beneath their shorts. A parade.

My ritual was always the same: a long hour on the machines, fifteen minutes in the sauna to sweat everything out, and a shower that left me feeling brand-new. The best part was that the sauna was almost never occupied. I used that solitary time to clear my head.

That November afternoon, it was cool outside. I put on my usual clothes, black pants and a gray T-shirt, packed my bottle, two towels, flip-flops, swim trunks, and toiletry bag into my backpack, and was through the door in under ten minutes. I trained chest and shoulders for an hour and a half in a surprisingly empty gym for a Monday, then changed to go downstairs and relax.

I walked down the long corridor to the room separating the different areas, that boundary where the air suddenly turns dense and hot. I crossed the nonslip floor, between white tiles and pinewood, and when I was a few yards from the sauna, I stopped dead.

There were two towels on the rack outside. One blue, one green.

I stood still, processing it. Someone was inside. The sensible thing would have been to turn around, wait in the locker room, or go straight home. I thought about it—I really did. But then, through the strip of glass in the door, I saw a movement that rooted me to the spot.

For a moment I thought I was mistaken, that the steam was playing tricks on me. Curiosity got the better of me. I moved closer sideways, keeping tight against the wall, and barely poked my head around the edge of the door.

I hadn’t been mistaken.

Through the haze I made out a woman’s foot, sole facing upward, pale-pink-painted toenails swaying slowly. And beyond it, the whole scene. A blonde woman with tanned skin, kneeling on the wooden bench, with a body that looked sculpted. Her head was bent over a man’s lap.

She was sucking his cock.

She was on all fours, one hand resting on his thigh, the other gripping the base of his shaft while she moved up and down with her mouth stretched wide open. She swallowed the whole thing. The guy’s cock was no joke: thick, rock-hard, glistening with saliva, and every time she pulled it from between her sucking lips, a thick strand stretched from the tip to her mouth. She was still wearing light-blue shorts and a matching top that barely contained her breasts, two large tits swaying inside the fabric with every movement of her head. He, meanwhile, had only kept his black athletic pants, fallen to his knees; his red shirt lay crumpled at his feet.

This isn’t happening.

But it was. And I couldn’t move.

Her lips traveled up and down his shaft without hurry, leaving a wet trail that the heat of the room seemed to multiply. She deep-throated him with expert technique, taking him all the way in and holding there for a few seconds with her nose pressed against the guy’s pelvis, gagging included, before slowly coming back up, savoring him. She traced circles over his glans with her tongue, sucked his balls one at a time, taking each fully into her mouth, then returned to his cock and sucked it hungrily, as though her life depended on it. The man had his eyes closed and his head thrown back against the wood, exhaling through his mouth every time she went all the way down. They made no effort to be discreet. They were convinced nobody could see them.

“That’s it, fuck, Noelia, keep going,” he murmured, grabbing her hair and gathering it into an improvised ponytail with his left hand. “Eat it all, you slut, that’s it...”

She answered with an affirmative sound without taking him from her mouth and picked up the pace. A wet gluck, gluck, gluck echoed off the tiles. With his free hand, he stroked her back and moved down to the curve of her buttocks, squeezing awkwardly because of her position, digging his fingers into her ass until he left red marks on her bronzed skin.

My body reacted before my mind finished understanding what I was doing. My cock had become rock-hard inside my pants, so swollen that the seam hurt me. I glanced back over my shoulder toward the empty corridor. Nothing. Only the extractor’s hum and the distant dripping of the showers.

The erotic charge of the situation, combined with the risk of anyone appearing, injected me with a mixture of fear and excitement I had never felt before. I placed one hand on the wall and, with the other, undid my pants just enough. I pulled out my shaft, already wet with pre-cum, and began stroking it slowly, holding my breath, alert to every sound from the corridor. The tip throbbed with every heartbeat, and after only two strokes I already felt ready to explode.

Inside, his fingers tugged at the edge of her light-blue shorts. Noelia straightened for a second, just long enough to slide the fabric down to her knees, along with a tiny dark pair of panties, then immediately went back to what she was doing, arching her back and pushing her ass upward. What an ass. Round, smooth, with two dimples at the base of her back and her pussy already showing between her thighs, swollen, shiny, lips parted and dripping. I bit down on my lip to keep from moaning. Driven by pleasure, the man began thrusting himself, raising his hips a few inches with each movement, fucking Noelia’s mouth while she let him, choking and gulping saliva.

That was when I noticed a detail that had escaped me. On her lower back, where the curve grew more pronounced, a green flash caught the room’s dim light. A small jeweled adornment that completed the tableau as if everything had been arranged for someone to watch. Looking closer, I understood what it was: an anal plug with a green stone set into it, planted in the tight asshole between her buttocks. The little slut had a plug inside her while she sucked another man.

And it turned out that someone was me.

I enjoyed one of the best wanks I can remember, hidden behind a door, stealing an intimacy that didn’t belong to me. Every time she moaned with her mouth occupied, every time he released a hoarse oath, a jolt ran through my whole body and made me squeeze my cock harder. With my thumb I gathered the pre-cum from the tip and spread it over my entire glans, sliding my hand up and down with that sticky sound that would give me away if anyone walked past.

“Do you like it?” she suddenly said, releasing him for a moment and giving him one long lick from his balls to the tip. “Do you like the way I suck you?”

“You suck me like nobody else, fuck,” he answered in a broken voice. “Don’t stop, eat it all.”

“You’re so hard...” she murmured, brushing her tongue over his glans and giving it wet little kisses. “You’re dripping in my mouth. Just the way I like it, hard for me.”

“You drive me crazy, you filthy bitch.”

“Do you want to come in my mouth? Are you going to fill my tongue with milk? Tell me—tell me you’re going to come for me.”

“Now, fuck, now...”

“Yes, give it to me, come in my mouth. I want to swallow it all.”

She bent down again, trapping the base between her lips and sliding over the entire shaft while her other hand had disappeared between her own legs. She was masturbating her pussy with two fingers, pushing them in to the knuckles and pulling them out glistening, while rubbing her swollen clitoris with her thumb in fast circles. She moved with a rhythm that was gentle at first, then grew urgent, splashing in her own juices. Their moans overlapped, growing faster and shorter. The end was near, and all three of us knew it, even though they believed there were only two.

***

The man let out a long growl and surrendered. He grabbed her head with both hands and pushed her onto his cock, impaling Noelia to the hilt as he came inside her mouth. His abdomen could be seen contracting, his balls tightening, while she swallowed, swallowed, and swallowed again, eyes closed and cheeks bulging with hot cum. When he released her, she moved away barely a foot and pulled the last spurts over her tongue, sticking it out so he could watch her swallow everything without losing a drop.

She held out until the very last second, and when she pulled away she reached for her own pleasure, driving three fingers into her pussy and rubbing her clitoris with her open palm, riding her own hand on top of the bench. The moans came from deep in her stomach. She came with a long tremor that ran up her back, arched her ass into the air, and folded her over the wood, her pussy spitting jets of juice that ran down the insides of her thighs.

I came at the same time as she did, my hand muffling a moan in my mouth, shooting streaks of semen against the tile and my own fingers, so many and so quickly that my legs began to shake. I cleaned myself as best I could with the towel, my cock still hard and dripping, unable to believe what I had seen.

They stayed inside like that, panting and laughing softly.

“It’s so hot,” she said between laughs. “Look at the state we’re in. I’m dripping everywhere.”

“You’re soaked, you slut.”

“You’ve left me swollen. Next time, you’re fucking me properly.”

When I saw them start to get up, instinct snapped me back to reality. I hurriedly pulled up my pants, clumsily, my cock still only half-soft, and took one last look inside.

Mistake.

She had turned her head toward the door. Our eyes didn’t quite meet, but the silhouette behind the glass was unmistakable. She had seen me.

I slipped away toward the locker room, praying that the steam had blurred me enough, that I was only a faceless shadow. I went straight into the shower and let the water pour over me for a good while, my heart still pounding against my ribs and my cock hardening again at the memory of her swallowing.

***

Minutes later, calmer, I put one foot on a bench to tie my sneakers. I remembered the scene with a clarity I could hardly believe. It was the first time in my life I had seen someone fucking in front of me, live, and the sensation had left my body electric. I put on my jacket, slung my backpack over my shoulder, and headed down the corridor toward the lobby.

When I turned the corner, I collided with someone.

“Ow! That was quite a hit.”

“Sorry, I’m sorry,” I said, bending down to pick up the backpack she had dropped.

“It’s nothing. It was my fault—I stopped right in the middle of the passage.”

I looked up and my breath caught. Blonde, tanned, her hair pulled into a ponytail, black leggings outlining an unmistakable figure. It was her. And from that distance I saw the fresh trace of semen still at the corner of her mouth, a small white residue she had wiped away in haste.

Our eyes met. Hers hesitated for barely a tenth of a second, but her mind had already recognized me. The shower steam hadn’t been enough of an ally.

“Well... hi!” she said, recovering with admirable ease. “My name’s Noelia.”

“Hi, nice to meet you. Adrián. Are you all right?”

“Yes, yes, don’t worry. I’m waiting for my partner and didn’t even realize where I’d stopped.” She smiled, and there was something in that smile that wasn’t entirely innocent. She ran her tongue slowly over her lip, cleaning away the trace that still remained, without taking her eyes off me. “I haven’t seen you around before. Have you been coming here long?”

“Not really. A couple of weeks.”

“Well then, I suppose we’ll be seeing each other...” She paused deliberately, holding my gaze, and lowered her eyes for a moment toward my crotch, where the bulge was still visible. “Apparently we share the same interests.”

I felt my face burn. I let out a nervous laugh.

“Maybe, maybe... Well, Noelia, I have to go. It was really nice to meet you. Have a good afternoon.”

“You too,” she replied, and I could swear she winked at me before turning around and walking away, swaying that ass which half an hour earlier had made me come against a wall.

I left the gym with a foolish smile and an erection that wouldn’t go away. That day’s workout had been, without question, much better than any other. As I walked home, the cold air hitting my face, I thought I was perhaps beginning to understand why so few people used that sauna.

And that, of course, I intended to keep using it.
