Relatos Ardientes

My Sister Came Into My Room at Three in the Morning

We’re a very normal family. My father has worked as a technical engineer at the town’s auto plant for almost thirty years, and my mother, two years younger than he is, is a body designer at the same company. A stable life, without surprises. The kind of family any neighbor would describe as boring if they saw it from the outside.

My sister Renata and I are only a year apart. She was always the typical unbearable girl: uptight, vain, know-it-all. One of those people who correct the way you hold your fork at dinner. But she was my sister, so putting up with her came with the package.

What I couldn’t ignore, no matter how hard it was to admit, was that she’d gotten insanely hot. Swimming, which she’d been doing since she was nine, had shaped a body anyone would notice as they passed by. And she’d inherited Mom’s fine features: high cheekbones, a wide mouth, honey-colored eyes. Living next to her was a constant torture, especially because my parents had tasked me with accompanying her everywhere since we went to college together.

But this isn’t about my sister. At least, not yet.

Renata had the habit of bringing friends over in the afternoons, officially to study. Usually there were three of them, all equally flirty, all with that mix of fake shyness and boldness that nineteen-year-old girls have. And all of them, without exception, found any excuse to call me to my door.

—Andrés, can you help me with this?

—Andrés, do you have a calculator?

—Andrés, do you know how to solve this equation?

Between five and six in the afternoon, my parents still hadn’t come home from work. That hour was mine. Mine and, usually, my handjobs. I had my favorite pages, my clear preferences — huge tits drove me crazy — and a well-honed ritual: dick in hand, two browser tabs, and the latch locked. Until one ordinary Wednesday, while looking at one of those photos, the idea hit me.

Camila was the nosiest of the trio. She was always the one who called first. So the next time I heard her say from the other room that she was going to ask me something, I left the computer screen open on purpose. A woman with enormous tits filling the whole monitor, nipples shining under the flash, tongue out and fingers spreading her pussy.

—Andrés, can I come in?

—Come in.

Camila came in with her folder pressed to her chest, her lips already parted in her usual smile. She looked at me, looked at the computer, looked back at me. I didn’t close the image.

—Do you know how to calculate this equation?

I walked over to her chair as if nothing were happening and put my hand on her back while I explained the process. My eyes weren’t on the notebook. They were on her cleavage. She noticed, and far from pulling away, she leaned a little closer to me.

—Hey, I see you like tits —she said softly, glancing toward the screen.

I feigned panic.

—Ah, shit, what an idiot I am, I didn’t even realize it was open —I closed the window with a theatrical gesture and dropped my gaze—. Don’t tell Renata, please. It’s my weakness, I can’t help it.

—And how about mine?

She said it without blinking. And before I could answer, she lifted her blouse, unclasped her bra, and shoved two small, firm tits right up at my face. Pink nipples, suddenly stiff, the areola tight as if asking for a mouth. I had done absolutely nothing and the girl was already half naked in my room, my dick tugging under my pants.

—They’re perfect —I murmured, and it was true.

I asked permission only with my eyes and touched them first with my fingertips, then with my palms. My hands were shaking, but the trembling was calculated. I needed her to see me nervous, harmless, grateful. I pinched her nipples slowly, pulling them outward, and watched her close her eyes and bite her lip.

—Don’t play innocent, Andrés —she laughed—. Things get talked about with you at college.

I didn’t answer. I lowered my mouth and covered one nipple completely, sucking it down to the back of my palate, while with my other hand I squeezed her other breast and rolled the nipple between my thumb and forefinger. Camila threw her head back and let out a sound I had to smother with a kiss. She kissed better than I expected, with a loose tongue and an open mouth, and she was already rubbing herself against my thigh without trying to hide it. I stood up for a second, locked the door, and came back.

On the bed we got undressed without speaking. Her body was a miracle of youth: narrow hips, taut skin, a tan line where she’d worn a bikini that summer, and a shaved pussy, from top to bottom, with small lips already shining. When I spread her legs to look properly, she let out a moan of anticipation. She grabbed my dick before I could say anything, gripping it in her fist and sizing me up with her mouth.

—Fuck, you’re thick —she whispered.

—Turn around —I told her—. I want to eat you out while you suck me.

I lay back and she positioned herself over me, both of us face-down, her pussy at my face and her mouth on my dick. The moment I had her pussy in front of me I buried my tongue in it without warning, from bottom to top, tracing her entire slit. She jolted and answered with her mouth, taking me all the way to her throat. She did it better than you’d expect from someone who acted dumb in class: she worked me with her lips at the base, ran her tongue over the head as if there were a candy between her teeth, and every so often pulled off just to spit and take me back in again, looking down at me with wet eyes.

I had to clench my teeth so I wouldn’t cum in her mouth too soon. I spread her pussy lips with two fingers and worked her clit patiently, with the flat of my tongue first, then in small circles, then sucking it as if it were a nipple. I slid my middle finger in very slowly, curved upward, and searched for her spot inside while keeping my tongue out. Camila started moving on top of my face, grinding herself, and after a few seconds she forgot about my dick and focused on panting against my stomach.

—I’m cumming, I’m cumming, fuck, don’t stop… —she said in a thread of a voice, with her lips pressed to the tip.

I felt her thighs clamp around my head and she went silent, her pussy throbbing against my tongue. Right then I shot my load in her mouth because I couldn’t hold back anymore. She swallowed it all, with two gulps, and then licked the tip so not a single drop was wasted. I did the same to her: sucked her pussy until I left it clean, her clit still throbbing against my mouth.

We got dressed in five minutes. I put a finger to her lips.

—Not a word. It’s our secret.

She nodded. But I knew she was going to tell her friends that same night. That was exactly what I needed.

The following Wednesday there was no training. The three of them came over after college and went into Renata’s room. Fifteen minutes later they knocked on my door. This time it was Daniela.

—Can I come in?

—Come in.

The computer screen once again had a picture of tits on it. Daniela didn’t even pretend to be interested in the assignment she was holding.

—Andrés, do you think mine are bigger than Camila’s?

She took off her blouse before she’d finished the question, and then her bra, with the ease of someone who had rehearsed it. And yes, they were bigger. Much bigger for her age, round, with dark nipples and skin softer than a little girl’s. But I wasn’t going to get into that absurd competition, so I knelt in front of her and kissed them calmly, first one, then the other, making them even. I ran my tongue along the crease, nipped her nipples at the base, and left them shining with saliva.

—They’re incredible, Daniela. And they’re yours. That’s the only thing that matters.

I locked the door. We undressed. This time she took the lead: she knelt in front of me, grabbed my dick with both hands, and took it into her mouth with such urgency that I had to pull her off after a few minutes. She moved up and down with her whole throat, letting herself sink until her balls rested on her chin, never taking her eyes off me. She pulled it out, spat on it, rubbed it over her tits by pressing it between both of them, and took it back in to the hilt.

—Wait, wait, I’m about to cum.

—Let me keep going a bit longer.

—Later. Now it’s your turn.

I laid her down and went down on her. I spread her legs and found a pussy fleshier than Camila’s, with lips open and already dripping. I licked slowly, unhurriedly, from bottom to top, always finishing at the clit. Then I shoved my whole tongue in, curled it against her walls, and when I felt her go loose I slid in two fingers and worked her from the inside without stopping licking her from the outside. She started moving against my face, grabbing my hair, pushing my head into her pussy as if she wanted to drown me.

—God, you do that so well, asshole… you can tell there’s something in the family —she muttered through her teeth.

The comment went right over me at that moment. I was too focused on finding her orgasm. But the phrase stuck somewhere in my head. Something in the family.

I lifted her, put her on all fours at the edge of the bed, and paused for a second looking at her open ass and her dripping pussy on top. I ran my head from top to bottom over her lips, still not entering, until I saw her arch and search for the shove with her hips.

—I’m going to fuck you.

—Yes, but don’t finish inside. Do you have a condom?

—No.

—Even better.

I went in slowly, holding her by the hips, sinking into her centimeter by centimeter. Then fast. She was nowhere near a virgin. Her walls gripped me with an experience that didn’t match her good-student face: tightening, loosening, pushing her ass back to swallow me whole each time. I fucked her hard, pulling almost all the way out each time and driving back in with a thrust, while she bit the pillow so she wouldn’t wake half the house. I pulled out, laid her on her back, lifted her legs to my shoulders, and kept going from that angle, watching her tits bounce with every bump and her pussy open and close to my rhythm. Within minutes both of us were making noises that could definitely be heard from my sister’s room. She brought one hand to her clit and rubbed it while I pounded her, and a few seconds later she came, soaking my thighs.

—On top, on top, on top —she panted.

I pulled out just in time, mounted her tits, and finished over her face, thick ropes falling on her lips, her chin, an eyelid. She licked herself without shame, ran a finger over her cheek, and sucked it too.

—Not a word —I told her again.

She smiled, nodded, and left.

That night, at dinner, Renata was acting strange. She wouldn’t look at me. She talked to Mom about training but kept her eyes fixed on her plate. Up to that point, I had not thought about her that way even once. But Daniela’s phrase kept circling in my head —something in the family— and for the first time I looked at Renata the way you look at someone who knows.

After the TV series, my parents went to bed. Renata grabbed my arm when I got up from the couch.

—Stay a while.

I sat back down. I brought her a glass of water. She held hers with both hands, as if it weighed something.

—Your friends behaved themselves, right? —I said, testing the waters.

—Andrés, I don’t know how to tell you.

—Your friends are horny sluts, I know.

—They’ve spent years figuring out how to seduce you. I’m not surprised by what happened.

She went quiet for a second and I threw the ball back.

—And you, little sister? I don’t know any boyfriend of yours.

—What does that have to do with anything?

—One of your friends let something slip today. Something about the three of you sharing things that aren’t exactly study notes.

She turned red. She started blinking very fast and within seconds tears spilled over. Renata, the vain one, the perfect one, crying on my sofa for the first time in years.

—It’s okay —I told her, and I hugged her—. Have fun with whoever you want. I’m not going to judge you.

—My only relationship with a guy was a disaster. And with Camila and Daniela… I found something I’d never felt before.

I hugged her tighter. She smelled like coconut shampoo and swimming sweat, and I, without wanting to, without asking, started getting hard against her thigh. She must have noticed. She said nothing. Neither did I.

—Come on, go to sleep. And bring me more friends, okay?

We laughed. A nervous laugh, too loud for the hour it was. I gave her a kiss very close to the corner of my mouth and dried her tears with my thumb. Then I went upstairs to my room, stripped completely, and jerked off thinking about her. Only her. I imagined her kneeling, sucking me, riding me with her tits bouncing against my face, face-down with her ass in the air waiting for my dick. The friends, that night, didn’t exist.

***

It was three in the morning when I noticed the sheets moving.

At first I thought I was dreaming. A warm pressure, a wet mouth around my dick. Someone was sucking me, slowly, with full tongue, taking their time. I lifted the sheets and saw her hair lit by the light coming in from the street. She was naked, her tits resting on my thigh, and she had me all the way down her throat.

Renata.

I pulled her up to my face and kissed her before she could say anything, with the taste of my own dick still on her tongue. We started with small kisses, then with tongue, then like we wanted to eat each other alive. It was the first time I’d kissed someone feeling like I didn’t have to behave.

I went down her neck. I bit her shoulders, sucked her tits one by one, pinched her nipples with my teeth until I heard her moan into the pillow, licked the line of her navel. I skipped her pussy on purpose and licked the inside of her thighs until she started trembling, so close to her groin that I could feel the heat of her soaked pussy against my nose without actually touching it. I lifted her feet, took them to my mouth, and licked her toes, one by one, while she held her breath as if she were holding back a scream. Then I went back down and spread her pussy with my thumbs. It was shining with juice, tighter and smaller than her friends’, with the pink inner lips peeking out between the outer ones. I buried my tongue in her all the way and twisted it inside. I sucked her clit until it was swollen. I slid in two fingers and hunted for her spot while keeping my mouth on her.

—Andrés, what are you doing to me… I’m going to cum.

She arched all the way and sank her nails into my shoulders. Her pussy clenched around my fingers, throbbing, and soaked my hand all the way to the wrist. But she wasn’t done. I turned her face-down and licked her ass slowly, patiently, running my tongue along the crease from top to bottom and circling her hole before slipping the tip in, opening her with my thumbs at the same time while the fingers of my other hand kept working her pussy from below. She moaned into the pillow and pushed back for more. A few minutes later she turned around, laid me on my back, positioned herself over me backward, and gave it back to me: she swallowed my dick all the way down her throat while I kept my mouth on her pussy. No one had ever done that to me before, and my sister was doing it. My head felt like it was going to explode.

We spent a while like that, eating each other out, both of us making the most impossible silence. I could feel her swallowing and coming back up, how she gripped the base with her hand, how she licked my balls when I pressed her clit with my tongue. The bed was soaked with saliva and I’d leaked several times without either of us touching me. Renata had been right at the edge at least twice in a row, covering her mouth with her hand so she wouldn’t wake the whole house.

—Little sister —I said in her ear when she lay back down on top of me—. Your ass is mine. But that’ll be another day. Right now I’m going to fuck you the way I’ve been imagining for days.

—Yes, yes, yes. Please.

She straddled me, grabbed my dick with her hand, ran it first over her clit —rubbed it slowly, up and down, soaking it— and then placed it at her entrance and let herself sink down. She took me all the way in with one movement and let out a long moan I had to smother with two fingers in her mouth. She was tighter than any of her friends, a fist of hot flesh squeezing me at every centimeter. She set the pace from the first second, slow, deep, as if she wanted to memorize the sensation. I held her hips and moved with her without forcing it. I wanted her to do it her way.

After a few minutes she started to loosen up. She leaned forward, pressed her tits against my face, and sped up, pulling my dick almost all the way out and then driving it back in hard. Each thrust dragged a muffled sound from her against my neck. I bit her nipples and squeezed her ass with both hands, setting the rhythm from below and digging my fingers into her flesh. She came on top of me and soaked my thighs, trembling all over, her pussy clenching in spasms. I turned her over, laid her on her back, lifted one leg to my shoulder, and kept going from that angle, driving deep with every push, staring into her eyes. She came again, with her mouth open and no sound. And again, when I started rubbing her clit with my thumb while I fucked her. I held on until I couldn’t anymore and unloaded everything inside her without warning, pinning her to the mattress while my dick throbbed inside her, dumping the last of it, gush after gush. I didn’t even think about what I was doing. By then it didn’t matter.

She lay on top of me for a long while, her breathing slowing against my chest, with my dick still inside her and softening slowly. I felt my cum slipping out between her legs and dripping warm onto my stomach.

—What a fool I’ve been for so long —she whispered—. I’m going to enjoy this, Andrés. No apologies.

She kissed me one last time, got up, and walked barefoot to the door. She blew me a kiss from the threshold, as if it were the most natural thing in the world, and disappeared into the hallway.

I stayed staring at the ceiling. The sheets were a mess. My mouth still had her taste on it.

I’m never going to find another woman like her in my life, I thought.

And in fact, I didn’t.
