My Sister Opened My Gift, and There Was No Going Back

The attic picture window trembled under the onslaught of the blizzard. Bilbao had gone silent that night, buried beneath a snowfall no one could remember ever seeing like this, and February fourteenth seemed frozen before it even began. It wasn’t warm inside, either. Marina, my sister, paced through the living room with the taut elegance of someone who can’t bear to stay still, wrapped in a gray silk dress that clung to her curves with almost insulting fidelity.

—I hate this day —she said, pouring herself a whisky without ice—. It’s a commercial reminder that people prefer sweet lies to uncomfortable truths.

I watched her from the sofa in the half-light, my twenty-three years weighing on my shoulders like an electric current. To her I was always the little brother, the one who looked at her with a devotion she pretended not to understand. But that night the snow had isolated us. There were no dates, no excuses, no doors through which to escape. There were only the two of us and the blood we shared, the same blood that burned in my veins when I saw the glint of alcohol on her lips.

—You don’t need chocolates, Marina. Or wilted roses —I replied, my voice rougher than I meant it to be—. You need someone who isn’t afraid of you. Someone who knows that beneath that architect’s armor there’s a fire no one dares to touch.

She turned slowly. Her sharp green eyes dissected me. She set the glass on the table and leaned against the grand piano, crossing her long legs, sheathed in sheer stockings that ended in stilettos.

—And you think you’re that man, Adrián? —she asked with a smile charged with dangerous condescension—. You’re my brother. You’re supposed to bring me flowers out of obligation, not analyze my desires.

—A lot of things are supposed to be one way. But today is Valentine’s Day, and I have a gift for you.

I got up and walked toward her. I could smell her perfume, that scent of sandalwood and warm skin that had been haunting me for far too long. I took a small box wrapped in red paper from the pocket of my hoodie and set it on the piano beside her hand.

—Open it. Or don’t. But if you do, you have to know there’s no going back. I won’t be the boy you protect anymore.

She held my gaze for what felt like an eternity. Challenge vibrated between us. At last, with her long fingers, she tore the paper. Inside, resting on a bed of black velvet, was a blood-red lace set, so explicit it was almost a provocation. There was a note in my quick handwriting: «Put it on for me, or I’ll have to put it on you».

The air in the room turned thick, hard to breathe. Marina took the lace in both hands, caressing the fabric with an expression I couldn’t decipher. Her chest rose and fell with an agitation that betrayed a pulse no longer that of a calm older sister.

—Do you know what this means? —she whispered without looking at me—. If I put it on, we break everything between us. We stain the family name in a way not even all the snow in Bilbao could wash away.

—The family name is already stained by how badly we want each other. Stop pretending. You’ve been looking at me for years when you thought I didn’t notice.

I stepped closer until my feet brushed hers. I took the box from her hands and set it back on the piano.

—Go upstairs. Put it on. And when you’re ready, come back down.

She looked at me one last time. There was no fear in her eyes, only a dark lust that had just awakened after years of hibernation. She took the red lace, turned, and went up the stairs. The sound of her heels on the wood was like the ticking of a bomb about to explode.

***

I was left alone, my heart hammering against my ribs. I walked to the picture window and watched the snow keep burying the city. We were trapped in a crystal bubble of sin. My hands trembled, not from fear, but from an animal anticipation that had been fermenting in the dark for far too long.

Footsteps on the floor above made me turn. The clatter of heels down the hallway was slow, deliberate, a rhythmic torture. Then I saw her appear at the top of the stairs.

Marina was no longer the cold, efficient woman who had gone upstairs minutes earlier. She had stripped off the gray silk and any trace of doubt. The red set clung to her body as if it had been woven onto her skin. The blood-red tone emphasized the whiteness of her thighs and the fullness of her breasts, barely contained by the lace.

She descended the steps without taking her eyes off mine. At thirty-six, she moved with full awareness of the power her maturity exerted over my obsession.

—Is this what you wanted to see? —she asked when she reached the last step, her voice laden with a frigid eroticism that tensed every muscle in me—. Your sister turned into your filthiest fantasy?

I didn’t answer with words. I crossed the room in two strides and caught her by the waist. When my hand brushed her bare side, she let out a short gasp. Her skin was burning. I pulled her against me, forcing her to feel the hardness of my desire through my pants. She dug her nails into my shoulders.

—Look at you... —she whispered, whisky on her breath grazing my lips—. You tremble like a child, but you look at me like a wolf. Do you know what our parents would say?

—They’d say we’re the monsters they created —I replied, and before she could answer I seized her lips in a violent, hungry kiss that tasted of betrayal and desperate need.

Marina didn’t resist. She kissed me back with a fury that left me breathless, her tongue claiming mine with the authority only she possessed. I drove her toward the large dark wood dining table, the same one that had always been the symbol of our family’s rectitude. I swept the table runner and a vase of dried flowers aside with my arm and lifted her onto the cold surface in one rough motion.

Her legs parted to receive me, the stockings brushing my hips. The image was obscene and perfect: her mature, full, experienced body on the table where we had always eaten as a family.

—There are no hierarchies tonight —I murmured in her ear, running my hands down her thighs and feeling the wetness already soaking the lace—. Tonight there’s only hunger. And you have as much of it as I do.

—Prove it —she challenged, throwing her head back and exposing her throat—. Break the taboo, Adrián. Break me.

***

The vase smashed to the floor, and that was the last sound that belonged to the world of sanity. Marina lay back on the wood, back arched and eyes fixed on mine, loaded with defiance and a lust that brushed against panic.

I showed the lingerie no mercy. I searched for the fastening on the lace and, with one sharp yank, freed the fullness of her breasts. Seeing them exposed to the cold living room while she shivered under my touch was like taking a shock. I took them in my hands, squeezing with a possessiveness that made her cry out.

—Damn it, Adrián... —she moaned as my lips marked her neck—. You’re going to destroy me.

—We’re already destroyed, Marina. Since that look at Dad’s funeral, the two of us knew this would end like this.

I tore off my own clothes with animal urgency. When my naked skin crashed against hers, the contrast made us gasp at the same time. She spread her legs wider, wrapping me with her powerful thighs. She looked at me in astonishment: the boy she remembered was gone.

I guided my desire to her center and found her soaked, ready. When I entered her, the world stopped. It was a total invasion that left her breathless. Marina threw her head back, claws digging into the wood, her face twisted between ecstasy and agony.

—Adrián! —she screamed my name, but it was no longer a warning. It was a plea.

I began to move with relentless rhythm. There was no delicacy, only the need to claim every inch inside her, to remind her that our blood was the same and that, for that very reason, no one would ever know her the way I would. The table shook with every thrust, carrying us away from morality and dragging us into the abyss.

Marina, the woman who always had control, was falling apart beneath my body. Her hands, which had once given orders, now clutched at my arms, needing to confirm this was real. Her moans turned incoherent.

—You’re mine, Marina... —I growled in her ear—. Of your blood and no one else’s.

—I’m yours... —she admitted, her voice broken—. Make me yours forever.

The climax hit us both with blind violence while the snow kept falling outside, erasing the traces of a world that no longer existed for us.

***

The echo of our gasps still floated between the beams when I lifted her from the table. Marina was limp, her gaze lost, as if reality had been drained from her bones. The red set lay on the floor, a strip of fabric that looked like an open wound on the rug.

—We’re not done yet —I whispered, carrying her in my arms.

I took her upstairs to the master bathroom, a sanctuary of black marble and mirrors. I sat her on the edge of the tub and opened the faucet. Hot water filled the space with steam, fogging the glass and isolating us even more.

Marina watched me with a new fascination. The authority that had always wrapped around her had transformed into a curious submission under the gaze of her younger brother.

—What are you going to do now? —she asked, recovering a hint of her commanding tone, though it now sounded like broken glass—. You’ve already taken everything from me, Adrián. My pride, my secret... even my place at that table.

—I’m going to wash the guilt off you —I replied, taking a sandalwood soap sponge—. And then I’m going to show you that a body like yours isn’t made for punishment, but for constant worship.

I got into the tub with her. I began to pass the sponge over her shoulders, down the curve of her back, with torturously slow movements. The steam made her skin shine. Marina closed her eyes and rested her head on my shoulder, but the water didn’t put out the fire: it only made it denser.

When I reached her breasts, my touch turned possessive. The soap let my hands slide with obscene ease. She let out a long sigh when my thumbs found her hardened nipples.

—Look at yourself in the mirror, Marina —I ordered, gripping the back of her neck to force her to see our blurred reflection—. The same face, the same eyes... and the same hunger.

She opened her eyes and saw herself: me, young, wrapping the body of a mature woman in an embrace that defied every law. That mix of the water’s purity against the dirt of our secret sent her adrenaline surging again.

—It’s such a beautiful sin... —she murmured, turning to straddle my thighs—. If we’re going to burn, Adrián, let it be the longest combustion of our lives. Don’t stop. Not until I forget my own surname.

***

The steam dissipated and the cold dampness drove us into the master bedroom. Marina’s room was a temple to her sophistication: black silk sheets, minimalist furniture, and that silence only money and loneliness can buy. Until that night.

I laid her in the center of the bed. The contrast of her wet skin against the black silk was a sight that would have made anyone kneel. She lay there, brown hair spread across the pillow, looking at me with a mix of exhaustion and anticipation.

—You’re insatiable —she whispered, though her hands were already searching for my wrists again, as if afraid I might pull away.

—You haven’t seen anything yet. Valentine’s Day isn’t over.

I went to her vanity and came back with a bottle of jasmine oil. I made her lie face down, pressing my hands against her shoulder blades. The cold oil spilled onto the base of her back, sliding over the curve of her hips. I began to massage her with almost clinical slowness, but loaded with intent.

—Relax for me —I ordered, my mouth against her nape—. If you trust my blood to love you, trust my hand to claim you completely.

I felt her resistance give way centimeter by centimeter. Marina buried her face in the pillow, letting out a moan that was half protest and half surrender. This wasn’t just sex; it was a claim. I was entering the most intimate place of the woman who had watched me grow up.

—God isn’t here tonight, Marina. It’s only us and this hunger that’s going to consume us.

She no longer fought: she cooperated, pushing back, seeking pleasure and limit together. In the darkness of the attic surrounded by snow, Marina stopped being my protector and became my carnal accomplice.

***

The air smelled of sweat and jasmine when a sharp sound tore through the atmosphere: her phone vibrating on the nightstand.

She tensed. She glanced sideways at the screen.

—It’s him... —she whispered, her voice breaking. It was her ex-husband, a controlling man who still believed he had rights over her—. Adrián, stop... I have to...

—No —I cut her off, gripping her hips with a force that allowed no argument—. You’re going to answer. But you’re not moving from here.

—Have you lost your mind? If he hears anything...

—If he hears anything, he’ll know you finally belong to the only man who shares your blood. Answer.

I put the phone in her hand just before resuming the movement behind her, slow, deep. Marina held back a cry and slid her finger across the screen with trembling fingers.

—Hello? —she managed, trying to sound professional, though the break in her breathing was obvious.

—Marina, why are you taking so long? I’ve called you three times —the voice on the other end sounded cold—. The storm has blocked the road, but tomorrow I’ll come to talk about the documents.

I didn’t stop. On the contrary. My thrusts made her body crash against mine with a wet sound that echoed in the silence. She clenched her teeth so as not to give herself away.

—Yes... tomorrow is fine —she said, with a gasp she disguised as a sigh of tiredness—. I’m a little tired from the snow.

—You sound strange. Are you alone?

At that moment I buried my hand in her hair and forced her to arch harder, invading her with a stroke so deep she lost control.

—Ah...! —she let out, and halfway through turned it into a forced cough—. Yes, alone. Adrián is sleeping in the other room.

Hearing our family name leave her lips while I possessed her under her ex-husband’s invisible gaze was the most powerful aphrodisiac I had ever felt.

—Then sleep. We’ll see each other tomorrow —he hung up.

Marina dropped the phone onto the rug and turned with renewed fury, wrapping her arms around my neck and kissing me with almost violent desperation. The risk of being discovered had set her on fire in an inhuman way.

—You’re a demon, Adrián... my little demon —she panted against my lips—. You humiliated me in front of him without him even knowing.

—I didn’t humiliate you. I set you free. Now you know you owe no one anything, except the blood that binds us.

***

The silence that followed the call was more deafening than the ringing itself. Marina was trembling, a mix of residual terror and desire that had left her defenseless.

—You made me sin in the most sordid way —she whispered, though her legs were twined with mine—. You’ve broken all my defenses.

—There’s still one left. The last one.

I got off the bed and picked up the torn remnants of the red set from the floor of the living room. The lace, though torn, was still strong. I returned to her side and, without a word, took her wrists. She offered no resistance. With slow movements, I used the red fabric to tie her hands to the carved headboard of the bed.

The image was exquisite: the most composed woman I knew, immobilized by the remains of a sinful gift, at the mercy of her own brother. The red lace against the whiteness of her wrists was the symbol of our pact.

—There are no names here, no titles, no past —I told her, positioning myself over her—. Only this moment.

Bound, her body offered itself completely, arching toward me. I kissed her again, this time with torturous slowness, tracing her belly, her heavy breasts. Knowing she couldn’t move, that she depended on my will to reach release, brought her to a state that brushed delirium.

I possessed her with a depth that sought the soul beyond the flesh. The bed creaked, rhythmic, relentless. Marina pulled at the red bindings, her muscles straining in a futile struggle that only increased her pleasure. Her moans were raw, stripped of all elegance.

—Don’t stop! Adrián, please, don’t stop! —she screamed, her face slick with sweat.

I took her to the edge again and again, stopping just before she burst, forcing her to beg, to admit that I was her owner, her brother, and her lover. When at last I allowed ecstasy to claim us, she screamed my name with a force that made the mirrors vibrate.

***

The first ray of sunlight slipped through the slats of the blinds. Bilbao was waking under a mantle of white, silent snow, a visual irony compared with the scene of carnal devastation that was the bedroom.

I sat up slowly. Marina was still there, her wrists still held by the red strips. Her eyes were open, fixed on the ceiling, with an absolute serenity that chilled my blood. There was no fear left, no guilt, no older-sister authority. Only the woman who had been claimed to the marrow.

I carefully untied the knots. Her hands fell onto the sheets, numb. I kissed her fingers one by one.

—It’s stopped snowing —I whispered.

She turned to me and, for the first time in my life, really saw me. Not as the boy to protect, nor as the mistake to hide. She saw me as her equal.

—The world is going to wake up now, Adrián —she said, recovering a new steadiness—. The phone will ring again, the lawyers will call, and tomorrow I’ll have to be the serious architect in front of everyone again.

—I know. And I’ll go back to being the brother who accompanies you to family dinners and watches you from across the table —I replied, stroking her cheek—. But we’ll both know what’s under your suit. We’ll know that the red from this Valentine’s Day will never wash out.

Marina smiled, a slow, dangerous smile that promised me a thousand more nights like this one. She leaned toward my ear.

—Out there, we’re the perfect siblings. In here, we’re the sin no one would dare imagine. Every February fourteenth, and every night hunger consumes us, we’ll come back to this altar. Because now I know no one can love me like the man who carries my own name in his veins.

She rose with majestic grace, gathered the remains of the red set, and walked to the fireplace. She struck a match and let the lace burn, watching as the flames consumed the last proof of our transgression.

—Get dressed, Adrián —she said, turning to me with that commanding look that now belonged to me—. We have a life to pretend and a secret to enjoy forever.
