My Girlfriend Brought a Chastity Cage to the Beach

September arrived and with it, at last, the vacation we had been planning for months. That year we chose a small town on the coast, a place of hidden coves and white houses called Punta Almez. No huge hotels or beaches with beach bars every hundred meters: we wanted to switch off, and we wanted to do it alone, Noa and me.

We had already spent a couple of nights in an apartment we had found by chance, with a tiny terrace from which you could see a stretch of sea. In the mornings we explored the surroundings, and it was her who insisted on going down to a nudist cove she had read about, a strip of gray sand hidden among rocks called Cala del Sauce.

Neither of us had ever done nudism before. It gave us curiosity and a little vertigo in equal measure, that mix that comes with everything you want but don’t dare say out loud. It was a good occasion to try something new, so we put two towels, a beach umbrella, and some sandwiches in the backpack and went down.

The stairs were endless, carved into the stone, and as we descended we saw that the cove was almost empty. Barely eight or nine couples spread out over the sand and the odd lone man. We planted the umbrella near the water, and then the real test began.

—Shall we do it? —Noa asked, biting her lip.

—Whenever you want —I lied, because my heart was pounding.

We sat there for a long five minutes, debating whether we had the nerve to take off our swimsuits in the middle of all that. In the end she took the initiative, as she almost always did.

—On three. One... two... —her voice was a mischievous whisper—. Three.

Off. Both of us at once, without thinking any more about it.

It was a feeling impossible to describe. I think it was the first time in my life the sun had hit me where it had never hit me before, and there was something absurdly liberating about it, about taking off not only your clothes but also some kind of armor. We were so comfortable that we even dared to walk along the shore and go into the sea, laughing like kids.

But that calm didn’t last long.

When we went back to the umbrella, I saw Noa rummaging through the bag with a smile I knew well. From inside she pulled out a small black plastic chastity cage, one of those we had bought half as a joke months earlier and almost never used. She held it in the palm of her hand like someone showing off a jewel.

—You’re not planning to stroll around showing that off in front of so many naked girls, are you? —she said softly, looking me up and down—. That would be a little embarrassing. Better we keep it well tucked away.

I didn’t have time to answer.

A shiver ran the length of my spine, and before I could even think about it I was already putting it on myself, with clumsy fingers and ragged breathing. She snapped the little padlock shut with a dry click and hung the key from a thin cord she wore around her neck, next to a shell we had picked up on the first day.

—That’s better this way —she said, and kissed me on the temple as if nothing had happened.

All of a sudden, without really knowing how, I found myself walking along the shore hand in hand with her again, the cage fitted snugly and the certainty that now we were definitely no longer going unnoticed. More than one person looked at us out of the corner of their eye, trying to hide it, all pretending to be watching the sea while their eyes kept drifting to my crotch. I could feel the heat rising to my face, a mix of humiliation and something darker I didn’t want to acknowledge.

There was one man in particular who wasn’t hiding it much. He was alone, a few meters away, on a blue towel. Thin, broad-shouldered, with that pale mark of someone who goes to the gym often. He couldn’t have been much over thirty. Every time we passed close by, his eyes came back to us, to her, to me, to the cage.

—He’s looking at you —Noa whispered in my ear, and I could tell she liked the idea.

That was where it stayed, for the moment. We went back to the umbrella, ate the sandwiches, chatted about nonsense while the afternoon turned golden. By then almost no one was paying attention to us, except that man on the blue towel, who was still there, patient, as if waiting for something.

At about four-thirty we decided to pack up. I had put my swimsuit back on over the cage, and she had slipped on a thin dress with nothing underneath. We started up the stairs and, just as we reached the first landing, we heard quick footsteps behind us.

—Excuse me —it was him, a little awkwardly, with his hands in the pockets of his shorts—. I couldn’t help noticing... what you were wearing. I thought it was incredible. I’d love to see you a bit more, if it’s not too much to ask.

We were speechless. Noa and I looked at each other, not knowing what to say, and I stammered the first thing that came to mind.

—It’s... it’s a game we play as a couple. That’s all.

—I know, I understand —he said, raising his hands—. I don’t want to bother you. Just looking. I’ll give you fifty euros if you let me watch you for a while. No touching, I promise.

He said it so seriously, so apparently without any hidden intent, that it completely threw me. I looked at Noa, hoping she would shut it down at once. Instead, she was looking at me with one eyebrow raised and a spark of amusement in her eyes. It took her a couple of seconds to answer; both of us did it at the same time, almost without meaning to.

—Okay.

He smiled in relief and thanked us as if we had done him the favor of his life. He said his name was Adrián, that his car was up top, and that he would follow us wherever we told him.

The trip was short and silent, with his car behind ours through the narrow streets of the town. When we parked in front of the apartment, I still could hardly believe what we were about to do. The three of us went upstairs, hardly speaking. I needed the bathroom, so I slipped in for a moment while they stayed in the living room.

From inside I heard their low voices, some muffled laugh from Noa, the sound of a belt. When I came out, she was standing in the middle of the bedroom and turned to me with a calm that made my skin prickle.

—I’ve changed my mind —she said—. Today you’re the one who’s going to watch. Sit there and don’t look away.

She pointed to a chair beside the bed.

My cock tried to react inside the cage and the tug was almost painful. I could not believe what she had just said. She wanted me to watch her with another man, to sit still in a chair and see a stranger touch her. I didn’t know whether to laugh or run, but there was something in her voice, that calm authority, that bound me tighter than any lock. Like a good submissive, I sat down with my hands on my knees and my eyes wide open.

Adrián took off his shirt and trousers slowly, never taking his eyes off her. She moved closer, pulled down his underwear, and before doing anything else, turned her head toward me.

—Look at me in the eyes —she ordered—. I want you to see every single thing I do clearly.

And without once taking her eyes off me, she bent over him. I saw the scene from the side: her mouth, her hands, his face throwing back with a rough groan. But she wasn’t looking at Adrián. She was looking at me, all the time, as if this were a message addressed only to me. It was the most disturbing and exciting thing I had ever felt, that fixed eye contact while she did to another man what she had so often done to me.

Then she pushed him onto the bed and climbed on top of him the other way around, their bodies crossed, each with their mouth on the other’s sex. I clenched my fists in the chair, the cage digging into me, unable to move and not wanting to. She kept seeking me out with her eyes over his body, making sure I didn’t miss a thing.

After a few minutes she suddenly straightened up, hair mussed and cheeks blazing.

—Come here —she said—. It’s time for you to help.

I got up like an automaton. Then I saw that, at some point I had missed, she had put in a small plug with a blue stone that glinted. She removed it carefully, covered Adrián in lubricant, and slowly let him penetrate her from behind, releasing a long sigh. In that position, with him inside her, she brought her hand to her neck, loosened the cord with the key, and at last unlocked the padlock that had kept me closed up all afternoon.

The release was almost as intense as an orgasm. I got hard instantly, aching and grateful in equal measure.

—Now you —she said, leaning back a little on him, opening herself for me—. Slowly.

I approached trembling and entered her carefully. The moment I did, I felt what I had never felt before: the pressure of the other body through the wall separating us, his sex pushing against mine from the other side. Noa grabbed me by the neck and kissed me with a fury I didn’t know she had, biting my lip, digging her nails into the back of my neck.

—I want both of you to give it to me —she said out loud, never once letting go of my gaze—. Everything.

We started moving without coordination at first, then found a clumsy but brutal rhythm. I could feel every thrust from the other, the double friction, her contractions between the two of us. It was a pleasure I didn’t even know how to name, an overload of sensations that blurred my mind. She panted between the two of us, repeating my name and giving orders at the same time, absolute mistress of what she herself had set in motion.

We didn’t last long. Noa was the first, with a cry that must have been heard in the street, and that tremor dragged both of us over the edge almost at once. We finished inside, just as she had asked, the three of us collapsed on the bed, sweaty and breathless.

***

We stayed like that for a while, in silence, hearing only our breathing as it recovered. Then Adrián got up without saying much, dressed slowly, and before leaving, left a bill on the entry table, quite a bit more than promised, along with a scrap of paper with his number scribbled on it “just in case you ever feel like doing it again.” He thanked us with a shy smile, almost the same one with which he had approached us on the stairs, and left.

When the door closed, Noa and I looked at each other, both of us flushed red, still not quite believing what had just happened. And then we started laughing, that nervous, uncontrollable laughter that comes after vertigo. I held her tight, she buried her face in my chest, and we stayed like that for a good while.

—Too much? —she asked at last, lifting her head.

—Not at all —I answered, and noticed the key was still hanging from her neck.

We had gone to that cove looking for a little freedom and came back with something else, something more complicated to explain, a day neither of us would ever forget. And while I helped her clean up, I knew without any doubt who would be in charge next time.
