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 coastal village, a place of hidden coves and white houses called Punta Almez. No huge hotels or beaches with beach bars every hundred yards: we wanted to disconnect, 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 overlooking a slice of sea. In the mornings we explored the surrounding area, and it was she who insisted we go down to a nudist cove she had read about, a strip of gray sand hidden among the rocks called Willow Cove.

Neither of us had ever practiced nudism. We were equally curious and a little dizzy with nerves, that mixture that comes with everything you want but don't dare say out loud. It was a good opportunity to try something new, so we stuffed two towels, a parasol, and some sandwiches into a backpack and headed down.

The stairs were endless, carved into the stone, and as we descended we saw that the cove was nearly empty. Barely eight or nine couples scattered across the sand, and the occasional lone man. We planted the parasol 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 spent a good five minutes sitting there, 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 usually did.

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

Off. Both of us at once, without thinking any further. Out of the corner of my eye I saw her pussy exposed, shaved close except for a thin dark strip, and the way her small tits moved as she bent down to fold her swimsuit. Her nipples had hardened from the air alone, two pink points crying out for a tongue.

It was an impossible sensation to describe. I think it was the first time in my life the sun had touched my cock and balls, and there was something absurdly liberating about it, as if we were removing not only our clothes but a kind of armor as well. We were so comfortable that we even dared to stroll along the shore and go into the sea, laughing like children, my cock swinging with every step and her tits gently bouncing.

But that calm didn't last long.

When we returned to the parasol, I saw Noa rummaging through her bag with a smile I knew well. From it she pulled a small black plastic chastity cage, one of those we'd bought half as a joke months earlier and almost never used. She held it in the palm of her hand like someone displaying a jewel.

—You don't intend to walk around showing that cock in front of so many naked girls, do you? —she said softly, looking me up and down, her eyes fixed on my dick, which was already beginning to swell just from hearing her—. It would be a little embarrassing. Better put it away properly.

I didn't have time to answer.

A shiver ran all the way down my back, and before I could even think about it, I was putting it on myself, my fingers clumsy and my breathing quick, fitting the head inside the cold plastic and passing the ring behind my balls. She closed the little padlock with a sharp click and hung the key from a thin cord around her neck, beside a shell we'd picked up on our first day.

—That's better —she said, kissing my temple as if nothing had happened.

Suddenly, without quite knowing how, I found myself walking along the shore by her side again, the cage snugly fitted and the certainty that now we had stopped going unnoticed. More than one person glanced at us, trying to hide it, all of them pretending to be watching the sea while their eyes drifted toward my caged crotch, that ridiculous cock peeking out, shriveled, through the plastic. I felt the heat rising into my face, a mixture of humiliation and something darker I didn't want to acknowledge, while Noa walked beside me, deliberately swaying her hips, knowing perfectly well that they were looking at her and at me, and enjoying every second.

There was one man in particular who made less of an effort to hide it. He was alone, a few yards away, on a blue towel. Slender, broad-shouldered, with the unmistakable build of someone who went to the gym regularly. He looked a little over thirty. Every time we passed nearby, his eyes returned to us, to her, to me, to the cage. He had a thick, heavy cock resting on his thigh, not fully hard, but swollen enough to draw attention. A good dick, the kind you noticed even when it was at rest.

—He's looking at you —Noa whispered in my ear, and I could tell she liked the idea—. And you're looking at his cock too, aren't you, darling?

I turned red up to my ears and didn't answer. She laughed softly and squeezed my hand.

***

That was where things stopped, for the moment. We went back to the parasol, ate the sandwiches, and chatted about silly things as the afternoon turned golden. By then almost nobody was paying attention to us anymore, except for the man with the blue towel, who was still there, patient, as though waiting for something.

At around half past four we decided to pack up. I had put my swimsuit back on over the cage, while she had slipped into 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, looking somewhat embarrassed, his hands tucked into the pockets of his shorts—. I couldn't help noticing… what you were wearing. I thought it was incredible. I'd love to see a little more, if that isn't asking too much.

We were speechless. Noa and I looked at each other without knowing what to say, and I stammered out the first thing that came to mind.

—It's… it's a game we play as a couple. Nothing more.

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

He said it so seriously, apparently without any ulterior motive, that it completely threw me. I looked at Noa, expecting her to shut it down immediately. Instead, she was looking at me with one eyebrow raised and a spark of amusement in her eyes. She took a couple of seconds to answer, and then we both spoke at once, almost without meaning to.

—Okay.

He smiled with relief and thanked us as if we'd done him the greatest favor of his life. He said his name was Adrián, that his car was up above, and that he would follow us wherever we told him to go.

The drive was short and silent, his car behind ours through the village's narrow streets. 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, barely speaking. I needed to use the bathroom, so I ducked inside for a moment while they stayed in the living room.

From inside I heard their low voices, a muffled laugh from Noa, the sound of a belt falling, the rustle of fabric. When I came out, she was standing in the middle of the bedroom, her dress already on the floor and her tits bare, and she turned toward me with a calmness that raised gooseflesh on my skin.

—I've changed my mind —she said—. Today, you're the one who's going to watch. Sit there and don't look away. If you close your eyes, I swear I won't take it off you for the whole week.

She pointed to a chair beside the bed.

My cock tried to react inside the cage, and the pull was almost painful, a hot stab that climbed into my stomach. I couldn't believe what she'd just said. She wanted me to watch her fuck someone else, to sit still in a chair while a stranger fucked her in front of me. I didn't know whether to laugh or run, but there was something in her voice, that calm authority, that bound me more tightly than any padlock. Like the good submissive I was, I sat down with my hands on my knees and my eyes wide open, feeling the plastic bite into me every time I tried to get hard.

Adrián took off his shirt and pants slowly, without taking his eyes off her. When he lowered his underwear, his cock sprang free, half-hard, thick, with the foreskin already pulled back and a dark, glistening head. It looked enormous compared with mine in its cage. She approached, took hold of it as if weighing a piece of fruit, and before doing anything else turned her head toward me.

—Look me in the eyes —she ordered—. I want you to see clearly everything I do to this cock.

And without taking her eyes off me for even a second, she knelt on the rug, took it deep into her mouth in one motion, and began sucking him all the way down. I heard her swallow, watched her spit saliva onto the head and massage it with both hands, pulling it out to lick his balls before taking it all the way back in. Adrián threw his head back with a hoarse moan every time she reached his throat. But she didn't look at him. She looked at me the whole time, that stranger's cock sliding in and out of her mouth, her chin shiny with spit and her eyes fixed on mine as if it were a message meant only for me. It was the most disturbing and exciting thing I'd ever felt, that unwavering eye contact while she sucked another man the way she'd sucked me so many times.

—It tastes delicious —she murmured, pulling it out for a second to speak to me—. Much thicker than yours, darling. It fills me completely.

Then she went back to eating him, tightening her lips around the base and moving slowly upward, sucking eagerly. I clenched my fists on the chair as the cage dug into me harder and harder.

Afterward she pushed him onto the bed and climbed on top facing the opposite direction, their bodies crossed, each with their mouth on the other's sex. From my chair I watched Adrián spread her pussy with his fingers and run his whole tongue over it, from bottom to top, stopping at her clitoris to suck it as if his life depended on it. She writhed on his face, grinding against him, while she continued swallowing that cock, which was now leaking pre-cum at the corner of her lips. The room smelled of wet pussy and sweat, and I, unable to move, felt the cage filling with a miserable fluid escaping through the bars.

—Put two fingers in her —Adrián asked, his voice broken.

—No —she cut in, turning toward me again—. The only person putting fingers inside me today is him. Not from the chair, though. Not yet.

And she continued with the sixty-nine, moving her ass over Adrián's face, letting him eat her and returning the favor with her mouth, never stopping her search for my eyes over that body, checking that I wasn't missing a thing.

After a few minutes she sat up abruptly, her hair tousled, her cheeks flushed, and her lips swollen from all the sucking.

—Come here —she said—. It's time for you to participate.

I rose like an automaton. Then I saw that, at some point I'd missed, she had put in a small plug with a blue stone that gleamed between her buttocks. She carefully removed it, leaving her ass open for a moment, a pink, dilated hole slowly closing. She coated Adrián with lubricant from the base to the head, crouched over him astride and facing away, took that cock in her hand, and very slowly began feeding it into her ass, gritting her teeth until she sat all the way down, his entire dick buried inside her and a long sigh escaping her chest.

—God, it's so big —she gasped, barely moving.

In that position, with him buried inside her ass, she reached up to her neck, undid the cord with the key, and finally unlocked the padlock that had kept me imprisoned all afternoon. The cage fell to the floor with a dull clatter.

The release was almost as intense as an orgasm. I became hard instantly, aching and swollen, my head purple and my skin pulled tight. She looked at it and smiled.

—Poor thing, look at you —she murmured—. Come here and put that desperate cock in my pussy. Slowly, because I don't want you coming in two seconds.

I approached trembling, knelt between Adrián's legs, and saw her there, impaled on that dick, her open pussy directly above it, glistening and waiting for me. I took hold of myself, aimed, and entered her in one slow thrust. The moment I did, I felt something I'd never experienced: the pressure of the other body through the thin wall separating us, Adrián's cock pressing against mine from the other side, so close I could even feel the pulse of his veins. I was fucking my girlfriend, doubly penetrated, another man buried to the hilt in her ass, and it was too much.

—Fuck, fuck —I gasped, unable to move from the shock of pleasure.

Noa grabbed me by the neck and kissed me with a fury I'd never known in her, biting my lip and digging her nails into the nape of my neck, her tongue still tasting of the other man's cock.

—I want both of you to give it to me —she said aloud, never breaking eye contact for a second—. Everything. Both dicks moving at once, fucking me until I can't walk. And come inside me, do you hear me? Both of you.

We began moving without coordination at first, then found a clumsy but brutal rhythm. Adrián thrust from below, driving into her ass with sharp strokes that made her bounce, while I took advantage of her upward movement to bury myself in her pussy to the balls. I felt every thrust of the other man through her, the double friction, my cock sliding against his with only a partition of hot flesh between us. I felt her contractions squeezing me, sucking at me, and also Adrián swelling inside her ass, throbbing.

—Harder —Noa gasped—. Fuck me harder, both of you. Come on, don't hold back.

I grabbed her tits with both hands, squeezed them, and pinched her nipples while I drove into her deeply. Her mouth was open, her tongue hanging out, her eyes half-closed, and she kept spewing filthy talk.

—That's it, yes, like that… you're destroying me… what a thrill, having two dicks inside me… Come already, I want to feel it, I want to feel you fill both my holes at the same time.

It was a pleasure I didn't even know how to name, an overload of sensations that clouded my mind. Adrián's cock rubbing against mine through her, Noa's tight ass, her pussy dripping, her tits bouncing beneath my hands, her voice like an unleashed whore ordering us around. She was the absolute mistress of the scene she'd created herself, and the two of us were nothing more than two cocks at her service.

We didn't last long. Noa came first, arching her entire body with a cry that was probably heard in the street, squeezing her pussy and ass around both cocks at once as if she wanted to wring us dry. That trembling dragged us both over the edge almost simultaneously. I felt Adrián come in her ass with a long grunt, each spasm of his ejaculation pulsing through the partition, and that set me off too. I unloaded inside Noa's pussy in three, four, five spurts that shook my whole body, gritting my teeth and thrusting until the last drop. We finished inside her, just as she'd asked, all three of us collapsing onto the bed, sweaty and breathless, the mixture of both our come leaking from between her legs and out of her ass, running down her thighs and staining the sheets.

***

We stayed like that for a while in silence, hearing only our breathing as it recovered. I watched a thick white strand run down the inside of Noa's thigh, and I didn't know whether it was mine or his, and realized I no longer cared. Then Adrián got up without saying much, wiped his cock with a towel, dressed slowly, and before leaving put a bill on the entryway table, considerably more than he'd promised, beside a piece of paper with his number scrawled on it, “in case you ever feel like doing it again.” He thanked us with a shy smile, almost the same one he'd worn when he'd approached us on the stairs, and left.

When the door closed, Noa and I looked at each other, both flushed, still unable to believe what had just happened. Then we burst out laughing, that nervous, uncontrollable laughter that comes after a plunge into vertigo. I hugged her tightly, she buried her face in my chest, and we stayed that way for quite a while, her come and mine still running down her thighs.

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

—Not at all —I replied, noticing that the key was still hanging around her neck.

We had gone to that cove looking for a little freedom and returned with something else, something more complicated to explain, a day neither of us would ever forget. And as I helped her tidy up, watching her walk naked down the hallway with her pussy still dripping, I knew without a doubt who would be in charge next time.
