My Wife Chose the Gym Instructor and I Watched

The last year we’d lived at full speed. I was the one who proposed opening up the relationship, but the one who really took it and ran with it was Lucía. It started out of curiosity and ended with her devouring every new experience as if she’d been waiting for it for years. Her friendship with Noa, who’d been moving in liberal circles long before we did, filled her head with fantasies she didn’t even dare to name at first.

At home, though, everything was calm. The kids were getting older and more independent, dinners healthier, our knowing looks in the middle of the afternoon. Lucía looked after herself with a consistency that showed in her body, and I’d added boxing classes to my training. The buzz that contact sports leave behind translated into rougher, hungrier sex. We’d moved on to fucking almost every day. It was enough for our skin to brush under the sheets and our hands would fly to each other on their own.

With a bit of organization, we managed two free weekends a month. The kids split their time between both families, and extra money from some investments we were running with Marcos paid for our getaways. Most of the time we went away with the same goal: to broaden our horizons. The meetups with Noa and Hugo, with Sara and Marcos, came one after another, and the six of us formed a group of pleasure-seekers who understood each other without needing to speak.

The classic swap had started to feel too small for us. Lucía discovered she liked meeting other men alone, and I discovered, almost at the same time, that watching her leave turned me on like nothing else. We were becoming something different. She was becoming a hotwife, and I, her cuckold.

The feeling of watching her get ready for someone else was hard to explain. They call it compersion, but to me it was more than that. Something addictive I can’t put into words, a blend of pride and desire that twisted me up inside every time I heard her close the door.

Lucía knows it and uses it. She enjoys the selection process, choosing, teasing me over every last detail. And then telling me everything while looking me straight in the eyes so she won’t miss a single one of my reactions. That night she wanted to go further. She wanted me to go with her to her next date. And the date was with one of the weight-room trainers at the gym we both went to.

“I’ve got a date with Bruno on Saturday,” she said as she undressed to get into bed. “The one with the green eyes. The one I’ve wanted to fuck for months.”

“Mmm. And where are you meeting?” I replied, already feeling myself hardening under the sheet.

“At his place. He says he’s going to give me a personalized workout in his private gym.”

Her hand slid up my thigh and closed around my cock. She started jerking me off slowly, firmly, while she described in detail everything she planned to do with the trainer. When she felt my throbbing warn her I was close, she quickened the pace and lowered her voice.

“You know the best thing about fucking Bruno? That you’re going to be in the front row. Sitting in a chair, right in front of us. And when he’s done, you’ll come in and finish inside me. I want to feel both loads mixed together, feel myself full, and when I pull him out, I want a jet of it to spill onto the sheets.”

I came with those words still hanging in the air. As soon as I caught my breath, I grabbed her by the hip.

“Sit on my face. I want your taste in my mouth.”

Lucía didn’t need asking twice. She climbed up to the headboard, spread her legs on either side of my head, and lowered her pelvis until her pussy rested on my lips. I didn’t waste even a second before starting to lick her, slowly at first, hungrily after that.

“I love your tongue,” she murmured, moving her hips. “That’s how I want it always, ready. For me and for whoever I tell you. Maybe I’ll ask you to get Bruno ready first. Mmm. Just imagine, seeing you suck his cock in front of me so he can fuck me afterward.”

The image hit me like an electric current. My cock, which had barely gone down, went rock hard again. Lucía noticed, reached out, and started stroking me once more.

“Does that turn you on? Then if that’s what turns you on, that’s what’s going to happen. You’re going to try new things. Very new things.”

She didn’t finish the sentence. Her body tensed and began to shake, taken by the night’s first orgasm. Without losing a second she sat up, planted herself on the mattress with one foot on each side of my hips, and lowered herself toward me. She dropped down hard, taking me all the way inside her. One hand on my neck, the other braced on my chest, she started riding me with tremendous force. The second orgasm came almost immediately. When she finally stopped, she slipped to one side and hugged me.

“Fuck. I’m wrecked from coming like that,” she said, and kissed me with a tenderness I took as the night’s closing note.

I stroked her from top to bottom, from back to neck, kneading her sweat-soaked skin.

“I love it when you touch me like that after sex,” she whispered. “It’s the perfect finish.”

“I love you,” I told her in her ear.

“And I love you too, baby.”

She was asleep within minutes. My head, on the other hand, wouldn’t let me rest. The scene she’d described kept replaying itself. Once I was sure she was sleeping, I slid my hand under the sheets and finished the job she’d left half done.

The next day, when I got home, Lucía greeted me in the kitchen by hanging from my neck with a kiss that got me hard instantly with the barest effort.

“Look what they sent me,” she said. She picked up her phone, opened the gallery, and showed me a photo of a thick, straight cock, crossed with prominent veins. “It’s Bruno. He said he was inspired and sent it to me at noon.”

“Nice tool. If he knows how to use it, you’re going to have a blast.”

“My mouth’s watering. I already told him you’re going to be there and he loved the idea. He told me he’s bisexual, that he has no problem interacting with you.”

“Then perfect. Do you already have a date?”

“Sunday. We’re training at his place and staying for lunch and the afternoon.”

We looked at each other with the faces of mischievous kids and sat down to eat.

“Are you training this afternoon?” she asked.

“Yeah, I’ve got boxing. I want to stop by the gym first to warm up.”

“I’ve got class with Noa. I’ll drop the kids off at my parents’ on the way.”

We were trying to get back to normal, but after talking about sex like that there was no way to cool off with an ordinary conversation. When we finished eating, I got up to clear the table and Lucía went out to the garden.

“I’m going to make coffee. Want some?” I shouted from the doorway.

“Iced, with a splash of whiskey cream.”

I prepared the glasses, dropped two ice cubes into each, and went out onto the terrace. The sight didn’t surprise me in the least: Lucía was stretched out on the Bali bed, legs open, masturbating while looking at her phone. I walked over with her drink and checked that Bruno’s photo was open.

“That cock really gets you going.”

“It’s the whole package that gets me going. The cock and the man attached to it,” she said, speeding up her hand.

I crouched down and, while she kept working her clit, I slid in two fingers. The moment she felt them inside, she started trembling and dug her nails into my arm.

“I’m coming, ahhh. Yes, so good.”

“You’d like it if that were his cock instead of my fingers, wouldn’t you?”

“I’d love it. I want him to fuck me now, to wreck me,” she said through clenched teeth.

When she relaxed, she lifted the glass and proposed a toast.

“To my cuckold.”

“To my hotwife,” I answered, clinking the glass against hers.

I sat down opposite her, looking at her glistening sex, and told her she was a goddess. She smiled knowingly and took another sip. Then she went to get the kids and I got ready for the gym.

I arrived half an hour before my class. After changing in the locker room, I went into the weight room and the first thing I saw was Bruno helping a girl with a machine. He turned his head when he noticed me, gave me a wink, and I returned the greeting half as a joke before getting on with my own thing. Half an hour later I went over to the ring room and spent more than an hour sweating, working off testosterone against the heavy bag until I was drained of tension.

On the way out I headed straight for the showers. I stripped, stepped into a cubicle, and left the lock half-caught. I soaped myself up, turned the water back on, and just then the door opened. Bruno came in without saying a word. He put a finger to his lips, turned to make sure the latch was shut properly, and let his towel fall.

He had a defined, lean, very well-proportioned body. But the surprise came when he turned to face me. Just as powerful, just as hard, and in the middle there was that cock I already knew from the photo. In person it was even more impressive.

He let me finish rinsing off and knelt down. He started sucking me with a skill that had my cock stone hard in seconds. Then he stood up and jerked us both off at once, one in each hand, with absolute mastery. He took me to the edge in record time. Just when I was about to come, he crouched down again, took the tip into his mouth, and sucked while keeping his hand moving. It was so intense it almost hurt, but I didn’t want him to stop for anything in the world.

When I emptied myself, he stood up and smiled at me. I felt indebted for that pleasure, so I gestured that I’d take the lead now. The moment I closed my hand around his cock I realized its true size: I couldn’t even span it, the thickness was outrageous. All at once Lucía’s face flashed through my mind, enjoying that caliber, and it pushed me on. I sped up, and when a movement of his hips told me he was close, I lowered my head without thinking and did to him exactly what he’d done to me five minutes before.

Bruno held the back of my neck until he came completely. It was the first time I’d ever done anything like that with a man, alone, and I discovered I didn’t dislike it at all. I lifted my head. He was smiling like a rascal. He grabbed his towel and bent down to my ear.

“On Sunday we finish the job,” he murmured.

I nodded. He opened the door and left, leaving me with a sweet taste in my mouth and empty balls.

When I got home, the kids were in the living room. I said hello and went straight to the kitchen, where Lucía was making dinner. I came up behind her, touched her ass, and she turned her head to kiss me open-mouthed.

“Mmm. He’s got a delicious cock. You still carry his taste, you bastard.”

“You found out already. It was him. He came into the shower and...”

“I know. He just told me and I’m so fucking horny. You stay with dinner; I need to let off steam. Imagining the two of you like that has made me sick with it.”

She left the kitchen and went upstairs. I stayed behind among the burners, knowing she was up there masturbating over what had happened, and that got me rock hard again. The whole situation was insanely arousing, hard to take, and we were both enjoying it more than ever. It proved that very often imagination outweighs the act itself. Although, this time, what Bruno was promising for Sunday looked like top-level stuff.

There were only a few days left to see if everything he had in store for us was as good as he claimed. For now, my first time alone with another man in the gym showers had been more pleasurable and more perversely exciting than I’d ever imagined. And with the element of surprise on his side.

I’d never had sex alone with a man, apart from the occasional rubbing during a swap or a threesome. I had no qualms about doing it again, either. But this was different, and it could be the first step toward a bisexuality I’d never even considered until then. By this point, with the life Lucía and I were living, I didn’t care in the slightest.
