The Night I Initiated My Sister into the Club

I left him at just the right moment, when Rodrigo already thought that afternoon was going to end with me. I was hot, soaked, a step away from letting myself be carried away by him and by everything he had planned for me. But then the phone rang and it was my sister. If she hadn’t called, things would have been very different. You can imagine where my head was while I drove to her house, still with my body on fire and my breathing shallow.

It took me twenty minutes to cross the city and, at every traffic light, I caught myself pressing my thighs together. It wasn’t that I’d been left hanging; it was that I’d spent the whole week imagining what that conversation with Marta was going to be like. Because from her voice on the phone, broken and low, I already knew she wasn’t calling me over something trivial. My sister only got like that when something was burning inside her and she didn’t dare say it out loud.

Marta was waiting for me, a little nervous. Diego, her husband, had stayed in the dining room with the TV on, and she led me straight to the bedroom and closed the door. She sat on the edge of the bed and looked at me with that face she used to make when she was little and was about to confess something important to me.

“I want you to be honest, as you’ve always been with me,” she said.

“I am. Tell me.”

“Lucía, our cousin, has been putting ideas into Hugo’s head, telling him she’s seen you and your husband at a swapping club. Several times, she says.”

I stayed silent for a second. Not out of embarrassment, but curiosity.

“And why do you want to know?” I asked her.

She lowered her voice, as if Diego might hear her through the wall.

“For almost a month now, whenever we’re in bed, your brother-in-law won’t stop repeating the same thing to me. ‘Imagine it, Marta, fucking someone else. Wouldn’t you like to try it?’ Every day, the same story. And the worst part is it ends up turning me on like crazy. Then he goes back on the attack: ‘I’d like to see you. I want to watch you suck another cock that isn’t mine.’”

“And you?” I pressed. “Forget about him for a moment. Do you want it?”

She bit her lip.

“Sometimes, yes. We got to our wedding as virgins, you know that. And now he’s proposing this just because someone saw you two in those places.”

I sat down beside her and decided to stop beating around the bush. If she wanted her big sister to tell her the truth, I was going to tell her all of it.

“Okay, Marta, do you two make love without taboos?”

“What do you mean?”

“That if you do it everywhere.”

She blushed and laughed.

“Yes, almost everywhere. From behind less often.”

“And have you never thought about having another cock in front at the same time as his?”

There was a long silence. She looked at me fixedly.

“Have you done it?”

“Yes.”

“And doesn’t it hurt?”

“Not at all.” I took her hand. “You don’t know what it is to feel valued as a woman. To be able to satisfy your own desires and, at the same time, please whoever you choose. When they can’t hold back any longer and they fill you, and then they both stay beside you, stroking you slowly… that can’t be explained. It has to be experienced. And the best part of all is you don’t lose anything: Alejandro and I go home more united than ever, whispering to each other everything we felt that night.”

I had her. I saw it in the way her pupils widened.

“Take us to one of those clubs,” she blurted out. “One day. Diego and me.”

“It has to be a Friday night. Or better yet, a Saturday.”

***

The following Saturday the four of us arrived at the club. My husband, Alejandro, was driving and wouldn’t stop joking to ease the tension, but Diego sat in the back seat silent, with Marta’s hand clenched between both of his. My sister had made more of an effort than usual: a short black dress, lipstick on, her hair loose. When our eyes met in the rearview mirror, I winked at her and she took a deep breath, like someone getting ready to jump.

The place was in a discreet warehouse, with no signs, at the end of an industrial estate. From the outside it was nothing; inside, it was a succession of dim rooms, red lights, leather sofas and a deep music you felt more than heard. At the entrance, we were greeted by the hostess, a dark-haired woman who already knew us.

“Would you do them the favor of showing them around?” I asked, pointing at my sister and my brother-in-law. “They’re new. We’ll wait here.”

Alejandro and I sat down, ordered something to drink, and after a few minutes a couple we’d run into several times came over to say hello. His name was Bruno; hers, Irene. Calm people, unhurried, the kind who know how to read a look.

“We’ve come with my sister and my brother-in-law,” I explained. “It’s their first time. I think you’d be a good start for them, if things click.”

Bruno smiled.

“Leave it to me.”

I suggested he take Marta to the dance floor in the dark room and that, from there, he use his means to guide her calmly toward the private booths. And that’s how it went. Diego, meanwhile, stayed glued to us, staring toward the door where his wife had disappeared.

“Sandra, your sister isn’t coming back,” he said, half nervous, half excited.

“Don’t worry. Go with Irene and I’m sure you’ll find them.”

***

While Diego walked away with Irene, another couple came over to us. We came to an agreement without needing many words: a look, a smile, a gesture toward the private booths. We left our clothes in the locker, took some towels, and headed into the warm darkness at the back, where the music came muffled and the air smelled of skin and desire.

The couple we’d made the arrangement with, Bruno and Irene, stayed behind; we lost ourselves on our own side, among bodies searching for each other in the dark. Alejandro held me by the back of the neck and I let myself be led, alert to every sound, waiting to recognize my sister’s voice among the moans in the distance.

And then I saw her.

My sister was on her knees on a low divan, sucking a cock with a dedication I had never seen in her, while another man was fucking her from behind, gripping her hips. Her hair was mussed and her eyes half-closed. She was a world away from the nervous woman who had sat on the edge of her bed a week earlier.

Diego, who came in right behind me, had his eyes lit up. Seeing her like that, his and nobody else’s, completely disarmed him. He stripped without anyone asking and, with his cock in his hand, came straight over to me and offered it. I didn’t think. I knelt down and started sucking him slowly, savoring the situation as much as I savored him.

At that moment, the man fucking my sister pulled out, satisfied. I saw my chance and signaled to Alejandro.

“Go. Take his place.”

My husband positioned himself behind Marta and slid into her in one thrust. I think that, with how wet she was, she didn’t even notice the man had changed. She was still blissfully absorbed, sucking another big cock, lost in her own pleasure. I was still with Diego’s cock in my mouth, taking it all in, feeling like the center of a scene I had orchestrated myself.

When the stranger came in her mouth, Marta turned around, her lips still shining, and discovered it was Alejandro fucking her. For a moment she froze. Then she gave him a soft slap on the thigh, almost a reproach, and immediately made up for it with a long kiss, sharing with him in his mouth the remnants of what she had just swallowed.

Diego, beside me, groaned and came. I let him rest for a moment and then got up to embrace my sister, who was trembling, but not from fear.

“Are you okay?” I whispered in her ear.

“Better than okay,” she replied, laughing against my shoulder. “Why didn’t you tell me sooner?”

***

That was as far as Marta and Diego’s initiation went. What came after was up to them. And the truth is they went on for a long time as an open couple, without guilt and without secrets between them. Every so often they’d call us, or we’d call them, and the four of us would get together on a Saturday night, just like that first time.

On the way home, that same early morning, Alejandro and I told each other everything in bed, as we always did. I confessed that seeing my sister giving herself over had turned me on as much as anything done to me that night. He laughed and said he’d already noticed.

Sometimes, when I remember my sister’s face sitting on the edge of her bed, asking me if it hurt, I laugh to myself. She had no idea what she was about to discover. And I had no idea how much I was going to enjoy being the one to open the door for her to a world neither of us ever wanted to leave again.
