Threesome at the Gym That Ended Up Being Four

If you’ve already read some of my confessions, you know that my girlfriend and I had been exploring everything that turned us on for quite some time. I’ll call her Lara, and you can call me Nina. We were both adults, had been living together for a while, and had a fairly open relationship with each other, but there was always one rule we wouldn’t negotiate: no lies and nothing without talking about it first.

We worked out almost every day after leaving college. The gym was much quieter at that hour, which was why we ended up noticing two people who started showing up far too often during our time slot. He was Bruno, one of the trainers. She was a mature woman who drew attention without even trying.

Bruno was one of those guys who knew exactly what effect he had. Tall, toned, broad-shouldered and narrow-waisted, with the kind of worked-out body that showed even beneath the simplest clothes. When he trained before starting his shift, he wore tight outfits that left little to the imagination, and more than once I caught him looking at Lara as if he wanted to undress her right there.

The other one was Rebeca. She must have been somewhere in her forties, but she looked incredible. Strong legs, firm buttocks, a flat stomach, and round breasts that didn’t need any help from anything. She had the face of a self-assured woman, the kind who had lived enough not to pretend modesty when she wanted something. And she wanted something, because in the locker room she always ended up asking us about Bruno.

One afternoon, the three of us happened to be alone in the showers. Rebeca undressed with a naturalness that left me staring at her longer than I should have. Water ran over her shoulders and breasts, and as she soaped herself, she let out a low laugh.

—I’ve been trying for weeks to get that trainer to look at me like a real woman instead of a client—she said, squeezing one butt cheek shamelessly—. With the bulge he’s carrying, you’d expect him to be hungrier.

Lara burst out laughing. So did I, although inside, an uncomfortable yet pleasant heat had coursed through me. Rebeca looked at us with that half-smile of a woman testing the waters.

—And you?—she asked Lara—. Is there something going on with him, or do you two just flirt?

Lara shook her head.

—No. She and I are a couple. Sometimes we play, sometimes we invite someone over, but nothing’s happened with him.

Rebeca raised her eyebrows and lowered her gaze for barely a second, as if the information had ignited something in her.

—Then I’m even more interested in you two than I thought.

We laughed, but once we got home, we kept talking about it. That night we were on the sofa watching some random movie when Lara asked me whether I really didn’t mind Bruno getting so close to her. I knew her well: behind the question was curiosity, not guilt.

—I don’t mind—I told her—. If you’re attracted to him, I’d rather know. As long as you don’t lie to me, we can talk about anything.

Lara gazed at me tenderly. She leaned in and kissed me slowly, as if thanking me for my honesty. I thought that would be the end of it, just a gym fantasy and nothing more. I was wrong.

As the days passed, Bruno grew closer to Lara. I noticed it in the way he corrected her posture with hands that were too confident, in the way he smiled at her up close, and in how she pretended everything was normal, then told me every detail afterward. Rebeca, meanwhile, began getting closer to me.

One afternoon we stayed talking outside the gym and ended up sharing a coffee at a place on the corner while an impossible downpour fell. Rebeca had a way of talking about intimate things without sounding dramatic. She told me about lovers, women, men, and her taste for trying things without apologizing. She wasn’t boasting; she was confessing. And the more she talked, the more I wanted to kiss her.

When I wanted to head back to the apartment, the rain was still coming down brutally. She offered me a ride, but I refused. She insisted so much that in the end she lent me a light jacket.

—You’ll give it back tomorrow—she said—. Or invite me upstairs and I’ll get it back at your place.

She said it smiling, but the insinuation hung in the air.

When I reached the apartment, I found Bruno coming out the door. He was damp from the rain and looked as if he’d been doing more than talking. We exchanged a quick greeting. I went inside and found Lara flustered, beautiful, with swollen lips and an expression that confirmed the obvious.

I waited a little before asking her. I didn’t want her to feel interrogated. In the end, she sat down across from me and swallowed hard.

—I have to tell you something.

—I’m listening.

—Bruno came upstairs with me because of the rain. We kissed. He touched me. I stopped him before things went any further because we didn’t have condoms.

I watched her blush before she continued.

—But I did suck him off.

The confession hit me straight between the legs. I crossed my legs without trying to hide it, and she noticed.

—Did that bother you?

—No. It turned me on. Tell me all about it.

Lara bit her lip, embarrassed and aroused at the same time, and began to talk. She told me that he’d pulled it out beside the door, that it really was big, that the most impressive thing was how heavy his balls felt in her hand, that at first she’d moved her hand slowly just to watch him gasp, and that afterward he’d held her hair with anxious clumsiness. She told me she’d taken it all the way in as far as she could, that she’d felt the tip hit her throat and that it drove him crazy. That he came quickly, shooting his hot load into her mouth with almost no warning.

While she spoke, I was already touching myself over my shorts.

—Come here—I said.

Lara came closer and I pulled her onto the sofa to kiss her. I thrust my tongue into her hungrily, imagining his taste still lingering in her mouth even though hours had passed. I took off her shirt and squeezed her small, hard breasts, pinching her nipples until she moaned. She opened my legs and slipped her hand between my thighs.

—You’re soaked—she whispered.

—Your fault. For swallowing that bastard and coming here to tell me about it like this.

I pushed her onto her back on the sofa, yanked down her pants and panties, and knelt between her legs. Her pussy gleamed with wetness. I spread her lips with my fingers and ran my tongue from bottom to top, slowly at first, savoring the way she trembled.

—This is how he left you, right?—I said before licking her again—. Hot and needy.

Lara answered with a hoarse moan. I thrust two fingers into her and she arched, digging one hand into my shoulder. I sucked her clit while opening and closing my fingers inside her, feeling her squeeze around my hand. It didn’t take long for her to start moving on her own, fucking herself on my fingers.

I kept thinking about her mouth wrapped around Bruno’s cock, and it made me wilder. I made her kneel on the rug and took the harness with the dildo we sometimes used from the drawer. I showed it to her, and she smiled, understanding exactly where my arousal was coming from.

—Suck it like you sucked him—I ordered.

I blindfolded her with her own blouse and pushed the rubber tip between her lips. Lara opened her mouth obediently and began sucking me as if it were real. At first she slid it in and out slowly, while I watched her salivate, swallow, and force her throat until soft gags came, yet she kept going. The sight drove me crazy.

I lifted her and put her on all fours on the bed. I spread her cheeks, spat on the dildo, and thrust it into her in one stroke. Lara cried out, not from pain, but from that abrupt impact that leaves your body open and your mind blank. I started fucking her hard, holding her by the waist, hearing the harness strike my pelvis and her moans grow increasingly disordered.

—That’s what you wanted, isn’t it?—I said, pulling her hair until her back arched—. To have that pussy filled and be made to moan like a slut.

I slapped one butt cheek hard. Then another. Her ass turned red and glossy. She gripped the sheets, moving backward to take me deeper and deeper, and when I brought one hand to her clitoris, she came screaming my name and his, mixed with curses. She collapsed trembling onto the mattress, sweaty, open, gorgeous.

When she had recovered a little, she lay me down and ate my pussy with obscene tenderness, as if she wanted to thank me and provoke me at the same time. She made me come in her mouth while she hugged my thighs. Afterward we lay there panting and laughing softly, unaware of how far that story would take us.

***

Two days later, I ran into Rebeca again. I told her she could stop by the apartment that afternoon for her jacket. She simply nodded, but there was determination in her eyes. We worked out almost in silence, looking at each other between sets with an electricity that was no longer innocent in the slightest.

In the locker room, for some reason, I decided to shower there. Rebeca did the same. Steam filled the space and isolated us. When I felt her body behind mine and the firm brush of her breasts against my back, I knew I wasn’t going to pull away.

She kissed my shoulder, then my neck. She slipped one hand around in front and gripped one of my breasts firmly, pinching my nipple while her other hand moved down my stomach. I raised my arm to grab her hair and pull her tighter against me.

—Don’t keep going here—I said in a broken voice—. Let’s go to my place.

Rebeca nipped just below my ear and let out an impatient laugh.

—You’re making me wait too long.

We dressed hurriedly and climbed into her SUV. On the way, desire mingled with nerves. Not because of her, but because of that strange feeling of crossing a new line. Even so, when we opened the apartment door, I went in first.

And froze.

Lara was standing with her back to us, hurriedly pulling down her top. Bruno was finishing putting on his shirt, visibly still aroused. They both looked at us with the same expression of guilty people caught in the act. I took a step back and bumped into Rebeca, who let out an almost amused snort behind me.

For several seconds, nobody said anything. Then Lara was the first to react.

—It’s not what it looks like—she said, then laughed at the absurdity of the phrase—. Well, yes, more or less it is what it looks like.

The tension broke with a beer. Then another. We talked. Rebeca, shamelessly, took it upon herself to say out loud what everyone was thinking.

—I think the two of us interrupted you two—she said, looking at Bruno and Lara—, and you two interrupted us. Since we’re here, we might as well stop pretending.

I felt heat rise through my body again. Lara looked at me from the kitchen with a bottle in her hand, and I returned a small smile. The air grew thicker with every drink. Nobody was hiding their looks or their hunger anymore.

—Just one thing—I said before everything broke loose—. Nothing without a condom, and nothing that isn’t stated clearly.

Everyone nodded. At that moment, at least, it seemed sufficient.

***

Lara was the one who took Bruno by the hand and led him to the bedroom. I followed with Rebeca, almost as aroused by watching as by participating. Lara pushed Bruno onto the bed and began kissing him with a confidence that lit a fire in my chest. She removed his shirt, ran her hands over his torso, and moved down to his sweatpants.

When she pulled them down, his cock came out hard and heavy, thicker than I had imagined. His balls hung taut and full. Lara wrapped her hand around him and began jerking him off slowly, enjoying the sight, while he slipped one hand between her legs and rubbed her pussy through her thong.

—Take it off—he said, his voice already hoarse.

Lara obeyed. She stood naked before him, and Bruno leaned in to suck one of her nipples while his other hand opened her pussy and pushed in two fingers. She moaned loudly. I was frozen watching them until Rebeca turned my face and kissed me hungrily.

Her tongue entered firmly, dominantly. We stripped each other in hurried pulls without stopping our kiss, and within seconds I had her standing beside the bed while I knelt to eat her pussy. Rebeca smelled of soap and fresh desire. I opened her lips with my tongue and felt her grab my hair to pull me closer. Above me, Lara was already sucking Bruno eagerly, plunging her head up and down while he held the back of her neck and breathed like an animal.

I put a condom on Bruno with my own hands when Lara pulled away to catch her breath. He looked at me gratefully, his mouth still wet, and then she climbed onto him. She took him inside little by little, with a restrained moan, until she was sitting completely on him. She began moving with a steady rhythm, her hands braced on his chest, her hair falling down her back, and I didn’t know whether to watch her pussy swallowing that cock or keep burying my face between Rebeca’s legs.

I managed to do both.

Rebeca lay down beside me and had me position myself above her so we could be in a sixty-nine. Her mouth fell on my pussy at the same time as mine covered hers. We licked each other hungrily, inserting fingers, sucking clits, panting against wet skin. I felt her opening beneath my tongue while, beside us, the bed creaked with Bruno’s thrusts from below and Lara’s rolling hips above him.

A hand stroked my back. Another spread my butt cheeks. I knew Bruno and Lara were close enough to touch all of us. Someone put two fingers in my mouth, and when I sucked them, that same hand went to my ass to lubricate my entrance with saliva and circular caresses. Rebeca moaned with my tongue inside her and stretched out an arm to grab Bruno’s balls, massaging them while she watched Lara ride him.

The room was a tangle of legs, mouths, and hands. Lara climbed off him to kiss me and slip her tongue into my mouth while I still had Rebeca’s taste on my lips. Bruno took advantage of it to stand at the edge of the bed, hard again, and Rebeca knelt without hesitation. She began sucking him with calm, expert hunger, taking him halfway in, pulling back to lick his shaft, kissing his balls before swallowing him again.

I watched her for a few seconds, fascinated. Then Bruno gently but firmly grabbed my hair and drew me toward him. I understood at once. I knelt on the other side and opened my mouth. Rebeca made room for me, and we shared his cock, one above and one below, taking turns with the tip and balls, our lips brushing against each other while he writhed with pleasure.

—Fuck... like that... don’t stop—he stammered.

Lara, kneeling behind us on the bed, caressed our shoulders and breasts while she watched. When Bruno began to tense, I lifted his chin with two fingers.

—If you’re going to come, let me know—I said.

This time he did. He pulled his cock from Rebeca’s mouth and held it in front of my lips. I gave him a few final slow sucks, and he came in my mouth with hoarse moans, filling it with thick, hot cum. I swallowed some, and passed the rest to Rebeca in a dirty kiss that made her close her eyes in pleasure.

Bruno dropped onto the room’s sofa to catch his breath. The three of us remained on the bed, still burning and far from finished.

I took the harness from the drawer and put it on without needing to explain. Lara let out an excited laugh when she saw it. Rebeca kissed her, laying her on her back and thrusting her tongue into her with a passion that tightened my chest with jealousy and arousal. They touched each other’s breasts, spread each other’s legs, and rubbed their pussies together while I positioned myself between them.

I pushed the dildo into Lara first. It slid in easily, her pussy already open and slippery. I began fucking her while Rebeca sucked her nipples and pushed two fingers into her. Lara didn’t know which of us to moan for. Then I pulled out the dildo and brought it to Rebeca’s pussy, which welcomed me by arching and squeezing it with brutal intensity. I alternated between them, watching them kiss, touch each other, come halfway, and ask for more.

—Don’t leave me out—Rebeca said, grabbing my waist to drive me deeper.

Bruno was hard again when he approached. I saw him from the corner of my eye while I continued penetrating Rebeca. This time he stood behind me and caressed my back before bending down to lick my neck. I moved aside enough to look him in the face.

—With a condom—I reminded him.

I watched him take one from the nightstand and put it on. Only then did I lean forward and offer him my pussy. He penetrated me slowly at first, perhaps to show he understood. I felt his thickness opening me, the firm thrust of his hips against my buttocks, and let out an involuntary moan that made Lara laugh.

I kept moving the harness inside Rebeca while Bruno fucked me from behind. The entire room began to revolve around that double rhythm: me thrusting forward and receiving thrusts from behind. Rebeca sucked one of my nipples, squeezed my waist, and panted with the dildo inside her. Lara, beside us, came with her fingers on her clitoris while she watched the three of us.

Bruno pulled out and turned toward Lara. She held out her hand to stop him for a second.

—Condom on or nothing.

He nodded and, since he was already wearing it, lay over her and penetrated her missionary-style. Lara wrapped her legs around his waist and began taking him with increasingly high-pitched moans. I took off the harness for a moment to kneel beside her head and kiss her while she was being fucked. I squeezed one of her breasts, and she bit my lip without looking away from Bruno’s eyes.

Rebeca made me turn toward her. She was on all fours, showing me her ass with a brazen smile.

—Let’s see if you really know how to use those fingers—she said.

I took lubricant from the drawer, wet her asshole, and began massaging it with one finger, then two. Rebeca moaned deeply, moving backward to ask me for more. Meanwhile, Bruno kept thrusting into Lara at a hard pace, the sound of latex and skin mingling with our panting.

When I felt Rebeca open and relaxed, I put the harness back on and pushed it slowly into her ass. She let out a muffled cry, a mixture of delicious pain and raw pleasure, then began taking it better, squeezing it with every inch. I held her hips and fucked her carefully at first, harder afterward, watching her clutch the sheets and beg me not to stop.

Lara was on the verge. I knew it from the way her thighs trembled. Bruno was too. She came first, squeezing him with her whole body, and seconds later he pulled out, removed the condom, and tied it off before dropping down and breathing deeply. That simple, necessary gesture released a tension I hadn’t realized I was still carrying.

We three stayed on the bed a while longer. Rebeca still wanted more, so she lay me on my back, climbed onto the harness, and began fucking herself on it with obscene skill, while Lara lay beside me to kiss me and play with my nipples. Watching that mature woman rise and fall on top of me, her ass tensing and relaxing, her pussy squeezing the toy and her mouth hanging open in pure pleasure, was enough to make me come without anyone touching me below.

Lara finished me with her hand, rubbing my clitoris until she brought me another short, trembling orgasm. Then she moved onto Rebeca, kissed her, and made her come too with her fingers, gazing closely at her as if they wanted to memorize each other.

When we finally stopped, the room smelled of sweat, latex, saliva, and recent sex. Bruno dressed first. Calmer now, and even a little embarrassed, he said goodbye without trying to be funny. Lara walked him to the door and came straight back.

Rebeca and I looked at each other, then the three of us burst out laughing. We ended up showering together, this time without rushing, washing each other’s bodies and going over what had happened amid jokes and confessions. The tension was gone; what remained was that strange intimacy that only appears after sharing too much.

Before leaving, Rebeca kissed both of us on the mouth.

—Next time—she said, grabbing her jacket—, let’s try to start this way from the beginning.

Lara closed the door and came to hug me from behind, still naked.

—So was it a threesome or a foursome?—she whispered in my ear.

I took her hand and guided it between my legs, where I was already feeling wet again.

—It was a rehearsal—I answered—. The good thing is, now we know four of us fit.
