What Happened with My Sister After Our Aunts and Uncles Left

My parents left us in the care of my aunt and uncle when we were kids. We have lived in Guadalajara ever since, in a large house with a garden, in a quiet neighborhood lined with trees. My sister Lucía is twenty-one and works at a municipal office she joined not long ago. I’m twenty and studying engineering. When our aunt Adriana and uncle Bernardo told us they were leaving for Italy for a month, the two of us looked at each other for a moment that lasted too long.

Neither of us said anything then. There was no need.

We had carried a secret for four years, heavier than we ever admitted. Before, we slept in the same room, in separate beds. When my uncle Bernardo built the upstairs room for me, it was under the pretext that we were already grown. The truth was different, and the three of us knew it without ever naming it. My sister and I had become something more than siblings, although we had never gone beyond long kisses and caresses over our clothes.

—Will you be okay? —my aunt asked me as she closed the last suitcase.

—Yes, Aunt. I’ll take care of Lucía.

My sister pretended not to hear me. She was on the sofa with a cup of coffee in her hands, her legs crossed and her brown hair falling to her jaw. She had that habit of biting her lower lip whenever something put her on edge.

***

We drove them to the airport together. When we saw the plane take off, Lucía squeezed my hand a little longer than necessary and let go as if it had burned her.

—I’m hungry —she said on the way back, looking out the window.

—Me too.

We stopped at a restaurant near Chapultepec. I ordered beers. She ordered tequila. The conversation was strange, fragmented, full of meaningful silences. My girlfriend Camila called me halfway through dinner, and I noticed the discomfort on Lucía’s face. She raised an eyebrow. Put down her cutlery. Asked for the check without waiting for me to finish the call.

In the car, on the way home, neither of us turned on the music.

—Camila loves you very much —she said finally.

—Yeah.

—You love her very much.

—Yeah. But you more.

Lucía turned her head toward the window. I saw her reflection in the glass. She was smiling despite herself.

—You hadn’t said it to me like that before.

—I’ve been saying it my own way for four years.

***

We got home around eleven. We only turned on the hallway light. The house, without my aunt and uncle, sounded different. Bigger. More ours.

Lucía left her keys on the console and took off her shoes without bending down, pushing one off with the opposite foot.

—It’s hot —she said—. Are you still hungry?

—No. I want something else.

She looked at me. She wasn’t biting her lip anymore. She was pressing it.

—Did you shower before we left? —she asked.

—Yeah.

—Me too.

She went up the stairs ahead of me. I stayed there for a moment at the bottom, watching her. She was wearing a short honey-colored dress and a back I knew by heart from all the times I had hugged her from behind in the kitchen, taking advantage of the fact that our aunt and uncle were watching TV in the living room.

—Are you coming? —she said from upstairs without looking at me.

I went up.

***

Her room was the same as always. The walls a very pale pink, almost gray. The window open to the patio. The bed unmade. Lucía never made her bed in the morning.

I closed the door behind me. It wasn’t necessary —we were alone in the house— but I did it anyway. It was a gesture. A way of saying that tonight we were going to be different people.

—I need to tell you something about Camila —I said.

—Later.

—It’s important.

—Later.

She came closer. Stopped in front of me. Pulled my shirt out of my pants with a determined movement, unhurried, as if she had been practicing it for years.

—Four years, Esteban. Four years kissing on the mouth and nothing else.

—I know.

—I don’t want to settle for that anymore. I want you to fuck me. I want you to fuck me until I don’t remember my own name.

She kissed me. It wasn’t like the kisses before. Before, there was always a calculation: the door, the footsteps in the hall, my aunt’s voice in the distance. That night there was none of that. Only her tongue forcing its way into my mouth with years of hunger, her broken breathing, her hands searching for my belt buckle and yanking my zipper down. She slid her hand inside my boxer briefs and grabbed my cock directly, without hesitation, squeezing it in her fist as if she were checking something she had been imagining for a long time.

—God —she murmured against my mouth—. You’re rock hard.

—Wait —I said.

—What?

—I don’t want to rush. I’ve spent four years imagining this.

She smiled. Sat on the bed. Pulled her dress off over her head in one quick motion. She wasn’t wearing a bra underneath. Her breasts were fuller than I had managed to imagine from the few stolen glimpses over the years: dark nipples, broad areolas, already hard and peaked. I stood there staring at her.

—What? —she asked—. You’ve seen me before.

—Never like this.

—Never like this.

She took off her underwear. The skin of her belly was pale and looked even whiter because of the tan line. Between her legs there was a little strip of brown hair, neatly trimmed, and below that her cunt was already shining. She spread her thighs just a little and with two fingers parted her lips so I could see everything. The entrance, pink, wet. The swollen clit peeking out from under its hood.

—Come here —she said—. Look at what I’ve been saving for you for four years.

I knelt at the edge of the bed. I kissed her thighs first, slowly, biting the skin on the inside, moving upward with my mouth open. When I reached her groin I caught her scent and my head went cloudy. I ran my tongue along her slit from bottom to top, flat and broad, tasting her for the first time. She tasted like a woman, like clean sweat, like something sweet and salty at the same time. I heard her let out a sound I had never heard from her before. Something between a sigh and a word that never finished.

—Oh, Esteban… like that, like that, you son of a bitch, like that.

I spread her cunt open with my thumbs and drove my tongue into the entrance, pushing it in, pulling it out, sucking her lips one by one. Then I went up to the clit and took it into my mouth, sucking it with my lips and flicking it with the tip of my tongue in quick circles. She writhed on the bed, clutched the sheets, grabbed my hair, arched her back off the mattress.

—Don’t stop —she said after a while—. Please, don’t stop, I’m going to come, I’m going to come in your mouth…

My tongue didn’t stop. I slid a finger into her cunt while still sucking her clit, and felt the walls clamp down on me. I pushed in a second. I fucked her with my fingers slowly, searching for the spot inside, curling them upward. Her legs started trembling in a way she couldn’t control. She pressed my head with both hands, then relaxed them, then squeezed again, closing her thighs around my ears. When she came, she let out a short cry that cut off on its own, as if she had been frightened by her own sound. I felt her cunt convulse against my tongue, squeezing my fingers inside in waves, and a gush of hot fluid flooded my chin.

***

—I’d never felt that before —she said when she caught her breath again. Her chest was rising and falling fast, her hair stuck to her forehead with sweat.

—Rodrigo doesn’t…?

—Rodrigo doesn’t.

—Never?

She shook her head. Her eyes were shining.

—He’s never licked my pussy. Says it disgusts him. I come by myself after. Thinking of you. With two fingers and a pillow between my legs, thinking about your mouth, your cock, about how I imagined you were going to put it in me.

She said that looking me straight in the face, not averting her eyes. And that was what finally broke me.

—I think about you with Camila too —I confessed—. All the time. I fuck her thinking about you. I close my eyes and it’s your face.

—I knew it.

—You knew?

—You’re my brother. I know you.

I took off the rest of my clothes. My cock sprang free, hard, pointing at her face. I saw her eyes go there, saw her lick her lower lip without realizing it. I knelt between her legs. She sat up and stopped me with a hand on my chest.

—Wait, now it’s your turn.

She made me back up to the edge of the bed and sat me there, with my feet on the floor. She lowered herself to the ground, kneeling between my thighs, and looked up at me from below. She didn’t let me speak. She grabbed my cock with her right hand and ran her tongue from my balls to the tip, slowly, never taking her eyes off mine. Then she opened her mouth and took the head in, sealing her lips around it, and started to go down. Her mouth encircled my cock with a looseness that surprised me and hurt me at the same time. I thought of Camila for a fraction of a second and pushed the idea away. This mouth was different. It was my sister. It was the four years. It was the reason I had been sleeping badly for so long.

She took all of it down to the base, swallowing it, feeling her throat close around it. She gagged for a second, pulled back to breathe, and went down again. She sucked me at first without making a sound and then noisily, sucking hard, making a wet sound every time she pulled off. She grabbed my balls with one hand and squeezed them softly while with the other she stroked the base of my cock in time with her mouth.

—Look at me —I told her, grabbing her hair—. I want to see your face while you suck me.

She lifted her eyes without taking me out of her mouth. Seeing her like that, with my cock buried between her lips and that look from my little sister turned into something else, took me to the edge.

—Lucía —I said—. Lucía, I’m going to come.

She didn’t move away. She squeezed my balls and kept sucking me faster, moving her tongue against the underside of the head. I came in her mouth in three long spurts, holding on to the headboard, gripping her hair, groaning her name. She swallowed. She swallowed everything. When she lifted her head, she wiped her lip with her thumb and looked at me.

—Camila isn’t the only one —she said—. You don’t let her come in your mouth either, do you? With me you can do whatever the fuck you want. I can take anything.

***

Almost an hour passed before I fucked her. I didn’t want to rush that either. I had her face-down again and ate her ass and pussy from behind until she came against my face for a second time, her face buried in the pillow so she wouldn’t scream. Then I turned her over and licked her nipples one by one, biting them softly, while she brought me back to full hardness with her hand. When I was hard again, she lay on her back, knees bent, soles of her feet planted on the bed. I was on top, one arm on either side of her head. My cock bumped against her belly, dripping saliva and pre-cum over her skin.

—Are you sure? —I asked.

—I’ve been sure for four years.

—Once it goes in, there’s no going back.

—Esteban. Put it in. Put it in already, little brother.

I grabbed my cock with one hand and ran it through the slit of her cunt, wetting it with her juices, rubbing the tip against her clit. She let out a gasp. I placed the head at her entrance and pushed slowly. I felt her open around me, tight, hot, in a movement that wasn’t only physical. I saw her face change. How she closed her eyes for a moment, opened them, closed them again. She swallowed my cock to the hilt with a single slow thrust, and once I had all of it inside, the two of us stayed still, breathing.

—You’re my sister —I said. I didn’t know why I said it.

—I’m your sister —she repeated—. And I’m your woman. And your cock is inside me. Move.

I started moving. Slowly at first, coming almost all the way out and then plunging back in to the base. She squeezed my waist with her legs, clamped them tight, held me back every time I wanted to pull all the way out.

—Rodrigo doesn’t let me do it like this —she murmured—. Without a condom. He’s never fucked me raw. Only you, Esteban. Only you are going to feel me inside.

—I do.

—I know. Faster. Fuck me harder.

I thrust harder. The bed started creaking against the wall. I grabbed one of her legs and put it over my shoulder so I could get in deeper, and she let out a long moan. Then I flipped her over without taking it out and put her on all fours. I grabbed her hips and started fucking her hard from behind, watching my cock go in and out of her cunt shining, watching her ass shake with every slam. I slapped her ass. Slapped her again. She arched her back and pushed backward, fucking me back.

—Like that, you son of a bitch, like that —she panted into the pillow—. Break me, break my cunt…

We stayed like that a long while, changing positions. Her on top, riding me, hands braced on my chest, sliding up and down my cock while I held her tits. On her side, with one leg lifted. Again underneath. Her body felt made to measure for mine, mine fit into her cunt as if it had been built for that. I thought maybe that was why we had waited so long: because we knew.

***

By one in the morning I had lost count of how many times she had come. She came on my cock, she came when I sucked her tits, she came when I whispered dirty things in her ear. I held out as long as I could. When I couldn’t hold out anymore, I told her.

—Inside —she ordered, squeezing my buttocks with her heels—. I don’t care. Come inside your sister.

—But…

—Inside. Please. Fill me.

I pushed in to the base and came with a long groan, feeling my cock jerk inside her, feeling myself shoot load after load into her. I felt her body accept it, twist, slowly settle. She came with me, clamping down on me in waves that squeezed out every last drop. Then I let myself fall on top of her, exhausted, with my cock still inside, feeling my semen begin to run down her thighs when I pulled out, and I stayed there, listening to her breathing return to normal while her hand stroked the back of my neck.

—I have to tell you something about Camila —I said at last.

She lifted her head slightly.

—Now?

—It’s what I wanted to tell you before.

I propped myself on my elbow. Looked at her. I spoke quietly, almost in her ear. I told her what Camila had confessed to me months earlier, after too many tequilas in a hotel downtown. That she had a brother and a sister. That the three of them liked each other. That they had done it several times. That she herself had told me she came thinking about them when she was with me.

Lucía stayed silent for a while. Then she let out a low laugh, almost disbelieving.

—She lent me a magazine to show you —I added—. It’s downstairs, in my briefcase.

—A magazine?

—About them. There are photos.

She sat up. Sat on the bed. Ran her hands through her hair. Between her legs my semen was still shining as it ran out of her.

—Go get it.

***

I went downstairs naked. The house, in the dark, no longer made me self-conscious. I came back with the magazine. It was dark-covered, with no visible title. I opened it on her bed.

Lucía, still naked, settled back against the headboard and opened it to the first page. I sat beside her.

The first photos were harmless: the three of them dressed, posing like siblings. But on the second page everything changed. Camila appeared seated on the sofa between her brother and her sister, the three of them naked, their mouths meeting in a three-way kiss, their hands between each other’s legs. The looks were not ambiguous. Neither were the hands.

—That’s her —Lucía said.

—That’s her.

—And those are her siblings.

—Yeah.

She turned the pages slowly. On one sheet there was a dialogue in interview form, as a caption.

—“Incest is the best, I love you all incestually, sisters” —she read aloud.

She closed the magazine. Looked at me. She was redder than when she had entered the room. I saw her nipples harden again.

—Esteban.

—Yeah?

—I want you to tell her.

—Tell her what?

—About us. I want her to know you’re not only hers either.

—Are you sure?

—And tell her that if she wants what she has with her siblings with you, then she has to have it with me too. That if she brings her to this bed, I’ll eat her pussy while you fuck her from behind.

I looked at her. She was completely serious. She still had marks from my fingers on her hips, my semen running out of her, and she was already thinking about what came next.

—Would you really be able to do it?

—I did it once with a girl from college. You think with her, who looks so much like me, I wouldn’t?

—You never told me about college.

—You never told me about Camila either.

I laughed. She didn’t.

***

When we fucked again, it was different. There was no calculation anymore, no threshold to cross, no line that wasn’t already on the other side. It was just the two of us, the siblings who at some point had become something else, finally without a mask. I mounted her, face to face, my cock inside her again, her tits brushing my chest, her mouth stuck to mine, biting my lips between one moan and the next.

—Do you want me to turn off the light? —I asked.

—No. I want to see your face when you fill me again.

And I saw her. I saw her close her eyes, open them, look at me, tell me things in my ear that can only be said to someone you grew up with —“deeper, little brother, deeper, all the way, like that”— in a mixture I have never felt with anyone else and never want to feel with anyone else again. I came inside her again, and she came with me, clinging to my neck, biting my shoulder to keep from screaming.

My aunt and uncle were coming back in thirty days. Thirty nights ahead of us. And an unfinished conversation with Camila that no longer scared me, because now I had someone to tell it to first.
