The Secret My Sister and I Keep at Home

Every Friday I pick Lara up when her classes at the university end, at three o’clock sharp. My week ends on Thursdays, so my afternoon is free, and today more than ever I want us to be together as soon as possible. For days I’ve been counting the hours.

I leave the car badly parked in a loading zone and, while I wait, I check my phone. I have two messages: one from the warehouse supervisor and one from the owner of the café where I work weekend shifts. Both confirm I can take the day off. For once, they give me time back, not money.

If anything has defined me over these last few years, it’s persistence. I needed to save up to move out on my own, and I racked up so many overtime hours that I sometimes put work ahead of sleep or classes I knew I could pass with my eyes closed. Today I’m cashing in part of that effort: free from the café tonight, free from the warehouse tomorrow. All I have left is to go to campus on Saturday for a group project with Daniela and Marcos.

I look back toward the street and, punctual as a clock, I spot my sister’s blond hair among the tide of students crossing through the gates. She spots me right away and comes running toward the car.

—Hi, darling —she hugs me the second she gets in, wrapping her arms around my neck and showering my face with kisses. I go crazy when she does that.

—How was your day, gorgeous? —I ask, hugging her back and kissing the top of her head.

—Pfff, a drag, as always. There was a seminar on a book in English and time just wouldn’t move. —Suddenly she lifts her eyebrows as if she’s just remembered something—. Hey, Hugo, have they replied about the job?

—Yeah, it’s all sorted. The only thing I can’t cancel is Saturday’s meet-up.

—Fiiine —she brushes it off with an eye roll—, but with how hard you work, they won’t get mad if you’re a little late, hee-hee.

—I’d love that, but it’s not an option. I’ve got a good group, I don’t want to let them down.

***

Desperate to get there, I step on the gas and, even with traffic, we’re parked within fifteen minutes. Our father’s car isn’t there. Perfect: today the house is ours until tomorrow.

We ride the elevator, and by then I can’t hold back any longer. I shove her against the back wall and shove my tongue down her throat, devouring her mouth the way I’ve wanted to for days. I grip her hard by the waist and the back of the neck, and I feel her moan softly against my tongue while my cock turns rock-hard all at once, pressing painfully against my fly. She notices immediately and rubs her hip against my bulge without the slightest shame.

—Mmm, Hugo, you’re killing me —she whispers, biting my lower lip and looking at me with those blue eyes that undo me—. You’re so hard, darling. I can feel it here, pressing into me…

—I know —I say into her ear, slipping my hand under her skirt and stroking her ass over her panties—. And you’re going to get even more worked up today. I’m going to fuck you so well you’ll forget your own name. I’m going to make your cunt raw, little sister.

Just as she’s about to reach for my cock, the elevator stops on our floor. We get out half-embracing, our lips already wet and her cheek flushed.

—Now stay still —I tell her, hurriedly searching for the key, my hands a little sweaty—. The only thing missing is Dad still being home, seeing us like this, and then it’ll all go to hell.

Lara nods in silence. I unlock the door, we go in, and I close it. I check the rooms to make sure we’re alone.

—Little sister —I announce triumphantly, grinning from ear to ear—, let the party sta…

I don’t finish the sentence. Lara throws herself at my neck with such hunger that for a second I fear we’ll fall backward. Luckily, it’s enough for me to take a couple of steps back to stop the impact.

—At last —she pants between kisses—. At last we’ve got a little time for us. I love you, darling. You have no idea how badly I wanted to kiss you like this, at home, without looking at the clock, without worrying.

She has a gift for this. She twists her whole body against mine, wraps her arms around my neck, and kisses me until I’m breathless, rubbing her breasts against my chest and slipping one leg between mine to grind her thigh against my cock. A real treat.

—Lara, my love… wouldn’t you rather take off your jacket and get comfortable? —I ask, because apart from the backpack she dropped in her room, she’s still dressed for the street.

—Hee-hee, oh, Hugo… —she sighs in a sing-song voice, shaking her head and pinning me with her gaze—. If you want me to get naked, all you have to do is ask.

—Wouldn’t want you catching a chill.

—I’ll cling to you if I do —she replies, pressing her lips into a sly smile and sliding her hands over my chest before moving lower and grabbing my cock through my pants, squeezing it brazenly.

—You’re already doing that, in fact —I laugh, kissing her again—. Let’s go to the bedroom, don’t waste time.

—Wait. —She pulls back smiling—. I’m going to the kitchen for water.

—Relax, I’ll wait for you in bed.

I go into my room and start undressing. While I imagine what’s waiting for us, I have a flash of common sense and shout from the room:

—Lock the door!

—We’re alone until tomorrow! —she answers from the other end of the apartment.

—Doesn’t matter, lock it! Dad could come back because he forgot something, and then we’d have time to act normal before opening. —“Better safe than sorry,” I think, taking off my shoes.

—Fiiine, I’ll do it now! —she agrees, and a moment later I hear the fridge door close.

With the door secured, I flop down on the bed in my boxer briefs and wait. She doesn’t take long to appear. She walks in with a huge smile and a look of desire that only fuels mine. Her eyes shine when she sees the tight bulge already marking my underwear.

—Hello, little brother —she greets me now in a slower, sexier tone, walking toward me at a deliberate pace to provoke me—. Ready to get up to mischief? I see you’ve already made yourself comfortable… and someone’s very happy to see me, hee-hee.

—Of course —I sigh, my breathing quickening—. I don’t want to lose a single second, baby. Let this be one of those afternoons we haven’t had in a long time. Come here. Stop teasing.

—Easy, there’s no rush —she says, and starts crawling across the bed toward me, her cleavage on display and her breasts swaying under her half-open shirt—. You’ll be able to fuck me as many times as you want. You’re going to fill me up completely, Hugo.

She climbs over my body until her face is level with my crotch. She brushes my cock with her nose, with her lips, lingering there on purpose, pressing over the fabric until a wet ring appears where her mouth sticks to the tip. Then she looks back up into my eyes, props her elbows on either side of my shoulders, and kisses me slowly, with a tenderness that contrasts with what we’re about to do. It’s a brother-sister kiss that would scandalize anyone who knew our bond, and that’s exactly why we love it.

I wrap my arms around her, but after a few seconds I feel her slide downward again, toward my waist, leaving a trail of kisses over my chest and abdomen.

—What are you doing there, darling? —I ask, her mouth still on my tongue, though I already know the answer.

Her answer isn’t in words. Without taking her eyes off mine, she kisses my cock over the fabric, drawing out the wait, nibbling at the tip through the cotton and rubbing her cheek against the bulge. She wants to torture me a little first, and I think that’s perfect.

Then she slowly pulls down my boxers and bares me. My cock springs upward, hard, swollen, the tip already shining with fluid. She stares at it from just a few centimeters away, with a devotion that turns me on even more, and licks her lips slowly enough to draw a growl out of me.

—Mmm —she murmurs at last, wrapping the base with her fingers and dragging it across her cheek—. I’ve been wanting to have it like this, right in my face, little brother. You’ve got such a thick cock. The veins even show. —And she starts planting short kisses all over my cock, from my balls to the tip, a slow little path that has me on fire.

She sticks out her tongue and runs it over the whole length from bottom to top, very slowly, as if she’s savoring an ice cream. She repeats the gesture several times, alternating with licks to my balls that arch my back with pleasure. When she reaches the top, she wraps her lips around the head and sucks softly, still not taking it into her mouth, teasing the tip with the edge of her tongue over the crown.

—Don’t torture me anymore, please —I beg her almost pleadingly, biting my lip and tightening every muscle—. If only you knew how worked up I’ve been for days. Seeing you around the house in barely any clothes when I get home at night, fresh out of the shower, stretched out on the sofa… and I can’t do anything because Grandma’s right there, with my cock hard under the cushion, trying to hold back from eating your pussy right then and there.

—Hee-hee, do you like coming home exhausted from university and the first thing you see is me, lying there with a low neckline, with the body you helped me build at the gym? —She speaks with her lips pressed to the tip, and every word makes my cock tremble.

—Hmmm —I grunt, picturing every scene she’s reminding me of—. You’re so wicked. I know perfectly well you do it to provoke me. That you choose your pajamas based on how filthy you want to get me.

—Did you ever have any doubt? —she asks rhetorically, while she goes back to kissing my cock along its length.

—Honestly, no. You’re a little incorrigible brat who would love for her big brother to kiss her in front of the whole family. —I say it with a mix of sexual irritation and raw arousal.

—Mmm, baby —she puffs out a breath, and finally opens her mouth fully and swallows me to the hilt, wrapping me in that wet heat I’ve been imagining for days—. I’m putting that fantasy on my list of things I want to try with you someday, hee-hee.

She speaks with my cock inside her, and the vibration of her voice shoots up my whole spine. She really starts sucking me off, moving her head up and down at a measured pace, sucking hard every time she reaches the tip, letting me see a strand of saliva connecting her lips to the glans when she pulls off completely. She takes me back in until it makes a sound deep in her throat, and keeps her blue eyes locked on mine without looking away for a second.

We both know the family fantasy is impossible. But words have power, and I won’t deny that imagining her offering herself like this, showing what we have, turns me on. Visualizing myself fucking her on any corner of the house sends me over the edge, and it shows: my cock gets even thicker inside her mouth.

—What are you thinking about, my love? —Lara asks, pulling me out for a moment to run her tongue over the corner of her mouth and wipe away the saliva—. She knows me too well not to realize when my head is somewhere else.

—All the filthy things I want to do to you —I answer shamelessly—. Bending you over the dining table and taking you from behind. Putting you on all fours on the sofa and filling your cunt until my cum runs down your thighs. —I moan when she finally gives herself over completely and takes me all the way in—. Lara… fuck, that feels so good, the way you suck me, holy shit…

—Mmm, so good —she murmurs, saliva running down her chin, spitting a little on the glans so her lips slide better—. I got you hard so fast. Shows you’ve been holding out for days. You won’t come soon, will you?

She starts jerking me with her hand at the same time as she focuses on the tip, sucking my head while her fist moves up and down the shaft with a firmness that makes me see stars. She wets her fingers with her tongue and strokes my balls with her other hand, squeezing them gently. I don’t know what to do with myself.

—No… I… ooh, God —I moan again, my legs tight and my fingers buried in the sheets—. I’m going to come, Lara, fuck, if you keep this up I’m going to come right now.

—Oh, really? —she asks, pausing for a moment and pulling me out with a wet pop—. And where do you want to finish, little brother? Where should I let you come?

—Pfff, don’t tempt me, darling —I assure her, reliving that filthy fantasy we’ve played out so many times—. You know I’d love to leave your cunt full, little sister. Soaked inside until it drips.

—Mmm, come on, it’s fine if nothing happens —she insists, smiling in that charming way she uses to seduce me, playing with the idea just to heat me up while she keeps jerking me slowly—. Put it in me with nothing. Knock me up, little brother. Let your cum stay inside me all night. I’m sure it would be perfect.

Everything trembles in me as I imagine it and, knowing it’s just a game between us —we always play it safe, this is pure shared fantasy—, I decide to play along.

—You’re that sure, little sister? —I ask, leaving the door open to see what she comes up with.

—Ohhh yes, completely sure —she confirms, with eyes shining in feigned delight, and runs her tongue over my glans while she speaks—. I imagine you surrendered, no holding back, coming inside me like an animal. That’s what turns me on most, Hugo. Feeling you empty yourself in my cunt. Really, it does.

I can’t deny that the idea, as a game, triggers that primal instinct we all carry inside. The fantasy seduces me more than I’d admit if I weren’t so worked up right now.

—Okay, then let’s keep playing —I declare with a wicked smile—: I’m going to fuck you like there’s no tomorrow.

My words have exactly the desired effect. They turn her on even more and she takes me fully again, setting a rhythm that leaves me breathless. She goes up and down faster and faster, sucking with hollowed cheeks, snorting through her nose, her throat open so she can take me all the way to the back of her throat. Saliva runs down her chin and drips onto her breasts, still covered, soaking her shirt. I growl, she moans with my cock inside her, and the walls of the room fill with wet sounds and our frantic breathing.

—You’re the best thing that ever happened to me, little brother —she tells me in a pause to catch her breath, scattering soft kisses over my cock and going back to jerking me with her saliva-soaked hand—. I have no doubt about that. I love you. —And she takes me back in, this time sticking out her tongue too to lick me from the balls to the tip, in a long dirty lick that almost makes me explode.

But the lack of sex over the past few days weighs on me, and soon I feel I’m at the limit. My balls contract, my cock swells even more inside her mouth, and I feel that tingle that announces the inevitable.

—Lara… aaah… I’m coming… little sister, I’m coming now, fuck…

At the warning, she doesn’t let up: on the contrary, she intensifies the pace, sucking my tip avidly and jerking the shaft with her closed fist, pinning me with her blue eyes so she won’t miss my reaction. I can do nothing but tense my whole body as I burst in a long-postponed orgasm. The first wave of semen fills her mouth at once, and she swallows each spurt without ever stopping the sucking, drawing out every last drop. I shudder, I groan her name, I bury my hand in her hair, and she doesn’t take her mouth away, swallowing and swallowing while I keep unloading in spasmodic bursts. Only a few drops escape and run down her chin, white and thick, dripping onto her breasts.

Once I’m done, I close my eyes and stay still for a few seconds, undone, while she keeps sucking me until my cock is completely clean with a tenderness that melts me. She gathers what escaped down her chin with her finger and takes that to her mouth too, staring at me fixedly.

—Did you get enough? —she asks softly, still between my legs, brushing my cock, still hard, against her cheek.

—Mmm —I sigh, relaxed, resting my hand in her hair in thanks—. Lara, little sister, you’re an angel. Of course I did. You didn’t have to swallow it.

—I know, hee-hee, but I felt like it —she answers, settling in and climbing back up toward me—. You know how much I like your cum. After all, I’m your woman, Hugo, and I’m proud to wring out every last drop from you. —She reaches my face and, before kissing me, concludes—: I want to take you with me everywhere, inside my mouth.

We kiss hungrily, both of us soaked in the kinkiness of the situation, and I don’t mind feeling my own taste on her tongue. We hug and caress each other at leisure, but her clothes are already becoming too much, so without saying much—my tongue is busy with hers—I start undressing her. She catches my intentions right away and helps, raising her arms so I can take off her shirt and arching her back so I can unclasp her bra.

Her clothes end up scattered across the bed and the floor, over mine, and it isn’t long before her curves are laid bare for my delight. Her breasts bounce free, round, with pink nipples already hard as stones. I pull down her skirt and panties in one tug, leaving her completely naked except for her socks, which I strip off at the same time. I move down from her chin and neck toward her breasts, pausing to lick her collarbone and suck her earlobe; I can feel her breathing quicken and her skin go as soft as always.

I catch one nipple between my lips and suck it slowly, playing with the tip of my tongue around the areola. She arches her back and moans, offering it to me more. I switch to the other and do the same, nibbling it carefully while I pinch the first between two fingers.

—Mmm —I growl between kisses when I reach the base of her neck and slide my hand between her legs—. You’re soaking wet, darling. It’s dripping onto the sheets. —My fingers sink into her folds, sliding through the wetness running down the inside of her thighs—. Your cunt is gushing, little sister.

—Yeees —she sighs, purring over my head and opening her legs for me—. How could I not be, when you touch me so well? I’ve been drenched since you stuck your tongue in me in the elevator, Hugo. I can’t even resist your kisses, my love. Don’t stop. You drive me crazy. Put them in already, please.

Carried away by the impulse, I wrap my arms around her and roll us over, so I can get on top and take care of her better. I look at her lying beneath my body, her hair tousled on the pillow, her hard breasts rising and falling with her breathing, her legs open and her cunt shining with slick. Now it’s her turn to enjoy herself.

—Looks like the one who wants to get up to mischief now is you, huh, you little rascal? —Lara teases me, smiling, her head on the pillow and her eyes fixed on mine.

—Of course —I assure her, lowering my mouth toward her breasts while my hands spread her thighs wider—. But first I want to take my time here.

My lips finally land on her chest and the reaction is immediate. I suck one nipple until it disappears entirely inside my mouth, pulling with suction, and my tongue circles the tip nonstop. With my free hand I grab her other breast and squeeze it, playing with the nipple between my fingers, pinching just enough to draw a sharp gasp from her.

—Aah, aah —she moans openly, arching her back and tightening her legs—. Hu… Hugo… so good. How… how you kiss. You wanted this. Keep going. Suck them harder.

Without warning, I slide two fingers between her folds and start stroking her clit with the pad of my thumb while the other two sink slowly into her cunt, feeling it close around me, squeezing, soaking my fingers to the knuckles.

—Oohhh! God! Yeees! So good, fuck! —she cries, frantic, bringing a hand to my nape so I won’t move away from her breasts even a millimeter—. Put them in deeper, Hugo, like that, like that, don’t stop.

I give her breasts the treatment I know she likes: slow and intense, alternating slow licks with hard sucks and the occasional gentle bite in just the right spot to pull gasps from her without going too far. At the same time, my fingers go in and out of her cunt slowly, curling upward to find that internal spot that drives her crazy, while my thumb traces firm circles over her swollen clit. I can feel her getting more and more aroused: moisture gushes between my fingers and runs down the crease of her ass onto the sheet.

—Aah! Keep going! Like that! Don’t stop, please! —she pants, arching again, moving her hips against my hand, releasing herself after several days of waiting—. Faster! More fingers, asshole, put more in me!

I add a third finger and speed up, fucking her cunt with my hand while I keep devouring her breasts. The wet sounds coming from between her legs are obscene, a steady sloshing that fills the room along with her moans.

—Don’t rush, baby —I soothe her, never stopping my attention, even though my own cock is once again close to bursting—. We’ve got the whole afternoon and the whole night. We can take it slow and make it sweeter.

—Aah, Hugo! So goood! You’re such an asshole! You get me hot, you drive me wild… and then you make me wait. Fuck me with your cock already, damn it, put that dick in me already.

—That’s not it, my love —I explain, without stopping the caresses, curling my fingers inside her and provoking a fresh jolt—. Believe me, nothing I want more is to lose myself in you until we collapse. Fucking you until you pass out, coming inside you, eating your cunt until you beg me to stop. You’re my sister, my girlfriend, and my life, and you know it. I’m only asking for a little patience so we can enjoy it more.

A professor once told me that when I set my mind to it, I have a silver tongue capable of talking anyone into reason. It must show, because Lara gives me a look that admits no argument.

—I want you to do everything you just described to me, Hugo —she orders, propping herself on her elbows and pinning me with her eyes, her breasts rising and falling with the rhythm of my hand between her legs—. You’ve got me really worked up, darling. Really slutty, for your brother.

I get back to work with everything I’ve got, sinking my fingers into her all the way with a fast, relentless rhythm, rubbing her clit with the palm of my hand on every thrust. I lower my mouth to her belly, kiss her navel, and trace a path of saliva down to the inside of her thighs. I pull my fingers out for a moment to bury my tongue directly on her clit, sucking it hard while I slide two fingers back in and keep moving them nonstop inside her.

—AAAAH! —she screams, arching her whole body and grabbing my hair—. YES! There! Eat it, Hugo, eat it all!

I spread the lips of her cunt with the fingers of my other hand and run my tongue from bottom to top, gathering all her taste before burying it again on the swollen clit. I suck, lick, bite softly, while the two fingers keep going in and out of her faster and faster. She writhes, clamps her thighs around my ears, pushes her hips against my face, asking for more.

—Aah! Yeees! Like that! Faster! —she pleads, wild—. I adore you, Hugo! Deeper! I’m cumming! You’re making me come, fuck, don’t stop, don’t stop!

Her pleasure explodes at full speed. Her whole body shakes in a long spasm, her legs tremble beside my head, and I feel her cunt clenching in waves around my fingers, soaking my hand and chin with a warm gush that runs down my wrist. I don’t let up until I hear her beg for mercy, and only then do I withdraw my fingers carefully, wipe my mouth with the back of my hand, and climb up beside her, holding her in my arms while she still sighs, her face flushed and cheeks wet, curling against my chest to rest.

—Did that do you good, my queen? —I ask, running my fingertips down her back, tracing a line of affection along her spine until I reach the curve of her ass.

—Mmm —she purrs, shivering, relaxed and adorable—. Yes. I needed that. So much. Thank you, my love. —And she lifts her head just enough to plant soft kisses on my neck and slowly climb the edge of my jaw, feeling at my hip that my cock is already hard again, pressing against her thigh—. And I think, little brother, that down here someone still wants more.

Outside, the afternoon keeps fading with neither of us having the slightest intention of moving from this bed. For once, time belongs only to us.
