My Sister Didn’t Get Up From My Lap That Afternoon

After the first round, we decided to stop to eat something. I’d planned for it that very morning: I stopped by the supermarket to buy a couple of trays of microwave pasta, just so we wouldn’t waste time in the kitchen and could make the most of every minute we had the house to ourselves.

We were both still fired up. The oral sex earlier had taken some of the edge off, but the heat wasn’t going anywhere. It was almost four in the afternoon and, no matter how much we wanted to keep going, our stomachs had the final say.

We’d put on some random daytime movie, one of those that nobody really watches. Lucía was already onto dessert when she started getting affectionate again. She rested her right hand on my knee, over the fabric of the pants I’d put back on, and slowly slid it upward.

—Come on, finish your plate and let’s get back to it. I want you so bad, Mateo —she urged me, smiling, as she trailed her caresses toward my crotch while kissing my neck and jaw.

—Mmmmm… —I growled, mouth still full—. Wait until I’m done. Don’t be so impatient, babe.

—You have to understand me —she insisted, kneeling beside me on the sofa and wrapping one arm around my neck, pressing her breasts toward my face—. So many days without being able to touch you the way I wanted. So many moments imagining you. So many times I had to act normal in front of Grandma so I wouldn’t ask you to take me off somewhere.

—Stop, Lucía… —I begged, growling again, though her words were already starting to get to me—. Don’t be so impatient.

—Impatient? —my sister repeated, stopping dead and pulling her face away from mine for a second, only to come right back at me—. No, my love, don’t get it wrong: I’ve already been patient enough.

And she went for my neck without hesitation, holding my face with both hands and kissing me hungrily. At that point, I decided to give in. My sister was burning up, and the truth was I understood her perfectly. She sat on top of me, spreading her legs, and whispered in my ear.

—Do you know how wet I am right now? —Her words made me hard instantly—. My pussy’s hot, and it’s because of you, Mateo. —She spoke with her lips brushing mine, grinding her hips against the bulge in my pants.

I wrapped my arms around her waist and, while I enjoyed her curves, decided that since she’d made me eat in such a hurry, it was her turn to work for the foreplay before we went back to bed.

Since she was half naked, I took my time touching her, but this time more slowly, letting her be the one to work at getting me so hard I couldn’t take it anymore.

—Mmmm… Lucía. For someone so desperate to fuck, you’re looking a little inactive.

—But I can feel your hard-on between my legs, dummy —she laughed.

—Sure, but even if it’s awake, I think you can make a bit more of an effort, my love.

—Are you asking me to tease you like a slut, little brother?

—Maybe… I don’t know… Try it and see if I like it —I challenged her.

—Fine. If what you want is to act difficult, I’m going to make it difficult for you not to give in. —She started moving slowly on my lap—. I’m going to make your eyes roll back, my love. And you know why? Because I’d eat you alive, Mateo. Because I’d happily swallow everything you’re refusing to give me right now.

She brought one hand down to her own underwear without taking her eyes off me.

—And you know what I’d do if you let me? I’d let you come inside me, deep inside, over and over, until there was nothing left. And I’m so wet you’d slide in without any effort.

Like a stake. That’s what her words left me like. Like a fucking stake.

I had to hold myself back from yanking my pants down right then and there and letting her ride me while she panted in my ear. Instead, I played along.

—You’re such a little bitch, Lucía —I shot back, intending to drive her just as wild—. Getting me so worked up like that. Touching your cunt sitting on my lap. What a filthy girl you are.

—Yeees… I’m filthy. I like my big brother. And I don’t just touch myself in front of him. I also… Ahhh… I also touch myself with nothing in the way. And I show him what he does to me.

Without a trace of shame, she pulled her hand out from between her legs and showed it to me: a clear, viscous fluid was sliding between her fingers and down her palm.

—See how wet you’ve got me, baby?

—Your cunt’s dripping —I observed, insanely turned on, noticing how my own pants were starting to soak beneath her.

—Yep. And I’m a clean person, so I have to deal with this somehow. And I can only think of one way.

Then, with total shamelessness, she licked her fingers a few inches from my nose and, in the middle of it, asked me:

—Want a taste? —And she laughed again, delighted with herself.

—You’re too much —I rasped, fighting the urge to bury myself in her to the hilt—. A little sex devil.

—Did you doubt it, Mateo? —she asked with a wicked smile, deliberately dragging her hand across her face, smearing her nose and cheeks—. I’m your woman. In public I serve you, and in private I give you what I know you want. Do you want it or not?

I smashed my mouth against hers and tasted her fluids eagerly, tongues and lips tangling in stop-and-start kisses. She took my right hand to the back of her neck, pressing so I wouldn’t pull away, while her left guided my hand to her underwear so I could check how soaked she was.

—You know what I’d do right now if you let me? —she told me between kisses—. I’d sit down slowly on top of you and not get up until I was hoarse. I want you, Mateo. Eat me.

She kissed me with a hunger I hadn’t expected, an intensity that made me moan into her mouth.

—I’d love for you to fuck me until we forgot everything. Until we screamed each other’s names. And I wouldn’t ask you to stop, baby.

Since my right hand was practically over her sex, I didn’t waste any time: I slipped my fingers inside her and made her pant against my face, soaking me with what came out of her.

—Aaah…! Mateo…! Yesss…! Keep going…! I…! I want you so much…!

—You’re an incestuous little slut who loves it when her big brother touches her without shame —I told her, and gave her an obscene lick on the cheek that left her skin shining—. Tell me, what do you think Dad would say if he saw us?

—I don’t know, Mateo. But I do know what I’d do. I’d let you come inside me. I’d love for you to do it without warning and for Dad to see everything: how his children love each other. How indecent this is.

She lifted her gaze and locked her eyes on mine.

—I’m dripping for you, my love. I’d go crazy if you looked at me like that while I came all over you. —And she bit her lower lip before delivering the verdict—: Fuck me.

***

Before I could react to her words, instinct took over and decided for me. I yanked down my pants and briefs in one go, my cock came out wet and dripping, and I shoved it into Lucía in one stroke.

—Aaah…!! —we both cried out almost at the same time. The penetration, given how lubricated we were, didn’t hurt at all.

My sister started bouncing on me, hungry. From the position we were in, I could see perfectly how she rose and fell, how I went in and out between her swollen lips, driving us both mad with pleasure.

—Ooooh…! Yesss…! —she panted, out of control—. My love…! Give me more…! I can feel you so deep…!

I devoured her breasts, her neck, her cheeks. I finished undressing her from the waist up and latched onto her nipples, sucking them as if I wanted to draw milk from them. They were delicious.

—Aaah…! Little sister…! —I growled, my head buried between her breasts while she squeezed them with her hands so I’d keep kissing them—. You’re delicious. How easily you take it. I love it.

I wrapped my arms around her body and slid my fingertips along her back. I felt her shiver and press closer to me, with real need. The heat and the smell she gave off had me spellbound, addicted to her body and her curves.

I could feel myself driving into her again and again, sheltered by the wet sensation of her walls taking me in. I would have wanted that moment to last forever, because the connection between us seemed simply unbeatable to me: together, we were one.

But, to my misfortune, with all the foreplay we’d done, the urge to come rose up uncontrollably and my whole body went into vibration mode.

—Lucía…! I’m… I’m close —I warned her, speeding up and sucking her breasts harder.

—Yesss…! I can feel it, Mateo…! Fuck me faster, baby —she begged me, and, grabbing the back of my neck, she pulled my face away from her breasts, lifted it, and leaned in to push her tongue all the way into my mouth.

Our breaths and our saliva mixed once more and, between ragged breathing, complicit looks, and licks, my eyes finally rolled back. I clung to her and started filling her from within.

—Aaah…! My loooove…! —I cried out, still with my mouth pressed to hers, holding her as she snorted, close to her own limit too.

***

As I finished emptying myself inside her and my cock began to lose strength, I worried, still panting, that Lucía might come too. I brought my thumb to her clit, swollen and slick with both our fluids, and started rubbing quickly.

—Oooh…! Oh my God…! —she moaned against my face, and I saw her features tense, her mouth slightly open, her jaw clenched with pure pleasure—. Yesss…! Mateo…! Like that…! Feels so damn good. Don’t stop.

—I’m not stopping, Lucía. It turns me on like crazy to make you pant like that. To rub you until you come. To make your eyes roll back.

I switched hands and brought the one that was slick with fluids to my mouth, sucked it a little, and offered it to her.

—Want some?

Without hesitation, she pressed her mouth to my fingers and started sucking, while I sped up down there. Her half-lidded eyes were the sign that the orgasm was approaching.

—Aaah…! Yesss…! Fuck, Mateo…! —she exclaimed while sucking—. I’m such a slut…! A filthy girl licking her own taste off her lips…!

Even though she’d swallowed a good part of it, some drops dribbled from her mouth and ran down her chin and neck, making their way toward her breasts. Spurred on by the filth of it, I held her neck with my other hand and lowered my head to gather up what was left with my tongue, from bottom to top.

—You’re delicious, baby. You taste amazing —I growled, feeling her pulse racing.

—My loooove…! Fuck…! There…! Don’t stop…! —she begged me, groaning loudly, her voice hoarse and broken, while I moved my fingers in circles that made her arch every time I hit her spot.

—Your cunt’s dripping, little sister —I told her to rile her up, feeling her wetness slide over my hand—. You’re soaked.

—Oooh…! Yesss…! From the heat you put into me, asshole…! Lick…! Lick my neck again…! I need it…! —she asked, throwing her head back and exposing her skin.

Obediently, I dragged my tongue over the places I knew she liked most, going up to the lobe of her left ear to suck on it. I felt her shudder while my fingers rubbed her a little faster with every second.

—I’m going to make you come, little sister —I told her, noticing how she dug her fingers into my shoulders and bit her lip—. I’m going to make you pant until your eyes roll back. You want that?

—Yesss…! Please…! Feels so good…! Please, Mateo…! Make me come…!

Her hips moved on their own, frantic, riding my hand like it was my cock, soaking my fingers. Her moans became more continuous, hoarse and trembling, desperately chasing that orgasm. I brought my other hand down to her ass and forced her to press harder against my fingers.

—That’s it. Come for me, Lucía. Come in my hand. Give me everything. Let me feel how you clamp down. I love you, my love.

Then, without warning, she tensed and sank her nails into my shoulders, opening her mouth to let out a scream that barely came out because she ran out of air, orgasming from head to toe.

—Aaaah…! —she finally exploded, a long, guttural moan that broke apart into gasps while her sex throbbed around my fingers, strong contractions soaking my hand up to the wrist—. Oooh…! Yesss…!

She started trembling all over, tears of pleasure in her eyes, her head thrown back. I kept rubbing without rest, stretching every wave that went through her, until she collapsed against my chest, panting, wrapping her arms around my neck with the same tremor in them as her legs.

I had her like that, vulnerable and grateful, and I kissed the crown of her head with all the tenderness in the world while I caressed her sweaty back with my fingertips.

—I love you —I whispered in her ear, my fingers still inside her, feeling the last spasms—. Enjoy it, my queen.

Lucía only nodded, saying yes, pressed to my body, her breathing still ragged.

***

Between digesting lunch and the orgasm I’d just given her with my hand, my sister got a little sleepy, with her head resting on my chest and her body relaxed and warm. Her hair tickled my chin, and her arms, wrapped around my neck, were soft and calm. She was absolutely delicious.

Honestly, I would have liked to let her sleep for a while. I know from experience that university cuts into her sleep, and that even makeup doesn’t always hide the dark circles.

I would have liked to, yes. But I couldn’t, for three reasons. The first, because I didn’t want to waste with sleep that absolute freedom we had until the next day. The second, because if I let her nod off, my sister, who always complains that we can barely be together, would have given me a proper dressing-down, and rightly so.

And the third, the most obvious: having her on top of me, naked, warm, with the smell of her fluids and my hand still slick with them, was making me hard again.

—My love… Wake up —I called softly, lifting her chin with my hand and kissing her on the forehead, the cheeks, the lips—. Come on, we’ve still got plenty of hours ahead of us for mischief.

—Mmmm… Yesss… I’m not asleep. It’s just that you touched me so well I got comfy. Thank you, little brother —she told me, and then she gave me a love kiss I hadn’t expected, with tongue and a lot of passion.

If I’d already been turned on, that kiss finished me off. I grabbed my sister by the legs, let her wrap them around my waist, and sprang up from the sofa toward the bedroom, ready for the third round.
