My Sister and Her Friend Caught Me on the Sofa

That June afternoon, the apartment was calm. My parents had gone to the country on Friday and my sister Daniela had left early with her friends for the neighborhood pool. The silence was so absolute I could hear the refrigerator humming from the living room.

I turned on the air conditioner, sprawled out on the living-room sofa, and propped my laptop on the backrest. I’d gone weeks without being alone in the house. There’s something strange about that empty stretch of time: a mix of boredom and a little thrill, as if the air itself were giving me permission to do things I don’t even dare think about the rest of the week.

I didn’t take long to open a video. I pulled my pajama pants down to my knees, leaned back on the cushions, and let my hand work slowly, wrapping around my cock, already hard before I touched it. I wasn’t in a hurry. I had the whole afternoon ahead of me to jack off while watching two chicks fucking on the screen.

What I didn’t account for was that the apartment door had been left unlocked from the inside. Daniela always forgot to lock it when she left in a hurry, and I never checked.

I heard the doorknob turn when it was already too late.

I barely lifted my head. In the doorway, with a canvas bag slung over her shoulder and her hair thrown up in a messy bun, was Carla. My sister’s best friend since high school. She was twenty-three, brown-skinned, with dark eyes and straight hair falling to her shoulders. She didn’t wear much makeup, but there was something about her features that made you look twice.

I froze, as if staying still could make me disappear. The dick was still standing in my hand, pointed at the ceiling, the tip shining.

—Dani told me to come pick up the charger she forgot —she started to say, and then she saw me.

She saw the laptop, saw my hand, saw the reddened cock between my fingers, saw everything. I jumped up and tried to haul my pants back on with a motion that didn’t help much: the fabric caught on the tip and stopped halfway, leaving my dick hanging out, hard and with nowhere to hide. My ears, my cheeks, my neck all burned. I wanted to speak and nothing coherent would come out.

—Hey —I said at last, in a voice that wasn’t mine.

Carla shut the door with her back, never taking her eyes off me. She looked for a long second between my legs before raising her eyes to my face. Then she set the bag on the floor and let out a short laugh, not mean, almost tender.

—How’s it going? —she asked, as if we’d run into each other in the building hallway.

I laughed too, without meaning to, out of pure reflex. I wanted to disappear. I wanted to go back forty seconds and hear the doorknob in time.

—Don’t get like that —she said, taking two steps toward the sofa.— It’s nothing. Happens to every guy. I’m not going to tell your sister anything.

That last sentence made my shoulders drop. I exhaled. Carla sat on the sofa arm, crossing one leg over the other. She was wearing short denim shorts and a tight T-shirt that showed the line of the sports bra underneath. Her thighs, brown and full, were a foot from my face.

She looked at me for a while without speaking. I no longer knew what to do with my hands, much less with my cock, which was still hard against the elastic waistband of my pants, making an impossible-to-hide bulge.

Go away. Go away and let me die alone on this sofa.

—Still —she said after a moment, biting her lip—, you don’t have to stop.

***

I went speechless. I thought I’d misheard her. I looked for some sign that she was joking, some smile saying “I’m kidding,” but there was nothing like that. There was a strange calm there, a decision made before speaking.

—Carla… —I tried.

—No, seriously —she cut me off.— If you want me to leave, I’ll go right now and this never happened. But if you stay quiet for two seconds, I’ll stay. And I’ll finish you off.

I didn’t move. The two seconds passed.

Carla got up from the armrest and stood in front of me, between my knees. She looked down at me, as if waiting for permission. I didn’t give it with words, but I lifted my hips a little so she could pull my pants the rest of the way down. She understood. She slid them down to my ankles without rushing and left them bunched on the floor. My cock sprang free, pointing at her face.

—Oh wow —she murmured, with a smile that was half mockery, half hunger.— Look what you’ve got hiding in here.

She knelt on the rug. She took me in one hand, closing her fingers around the shaft, and ran her thumb over the tip, spreading the shiny thread that had gathered there, looking me straight in the eyes the whole time. I gripped the sofa cushions. The sensation was so different from my own hand that I struggled to breathe.

—Easy —she murmured.— We’ve got time.

She tilted her head and stuck out her tongue. She licked me from base to tip, one long flat stroke, then sucked on my balls one by one, mouth open, covering me in spit. She came back up and took me into her mouth, slowly, almost testing how much would fit. She closed her eyes and started moving up and down with a slow, drawn-out rhythm, taking me a little deeper each time, until I felt the tip hit the back of her throat and she coughed lightly and came back up with a string of saliva hanging from her lip.

—Mmm —she moaned with her mouth full, and the sound hit my cock like a shock.

I felt her tongue circling the head, felt the pressure of her palate, felt the fingers of her other hand resting on my thigh and then dropping to grab my balls, weighing them as she kept sucking me. She began to speed up. I heard her swallow, heard wet noises, heard the slapping of her saliva. She took me all the way out, spat on it, and shoved it back down to the base with teary eyes. The living room shrank to that corner, to the patch of light coming in through the window, to the sound of her mouth eating my cock.

I realized right away I wasn’t going to last long. I touched her shoulder.

—Wait, wait.

Carla pulled back, lips shiny and a little swollen, and smiled.

—I know. Fine. You’re not cumming yet, idiot. We just started.

She stood up and pulled her T-shirt over her head. She tossed it on top of the bag. She unclasped her bra and let it fall. Her tits weren’t huge, but they were firm, lifted, with dark, hardened nipples pointing upward. She pulled down her shorts and panties at the same time. She was completely naked in the middle of the living room in my house, on any random Thursday afternoon, with her shaved cunt glistening between her thighs, already soaking wet.

She came back up to the sofa, pushed me gently back so I’d lie down, and climbed on top of me, one knee on each side of my waist. But she didn’t ride me yet. She climbed a little higher, until she was pressed over my face, knees against the backrest and her cunt millimeters from my mouth.

—You up for it? —she asked.

I nodded. I grabbed her ass with both hands, squeezing, spreading her cheeks apart, and pulled her closer. Her pussy was hot, shining, with a clean, strong smell that filled my nose. I stuck out my tongue and started working over her, first on top, sucking her lips one by one, then tracing circles around the swollen clit, feeling her jerk each time I ran my tongue over it. I pushed my tongue inside her, as far as I could, and she pressed my face between her thighs.

—Just like that, just like that, don’t stop.

I didn’t stop. I buried my tongue in her and sped up, alternating between sucking her clit and sliding the tip into her cunt. She started rocking against my mouth with her hips, setting a rhythm she kept losing. I felt the trembling in her thighs, her nails digging into the sofa back. She smeared my whole face with her juices and I swallowed what I could and kept eating her pussy as if I’d done nothing else in my life. She bit the back of her hand to keep from crying out.

—Stop, stop, enough —she gasped.— I’m going to cum and I don’t want to yet. I want to finish with you inside me.

She got down, fixed her hair, and laughed as if she’d only just realized where we were.

—Come on —she said.— I want on top.

We switched places. I sat back against the sofa, she settled on top of me again with her knees on either side, and she took my cock in one hand, rubbed it against her pussy lips, moistened it with her own slick, and eased herself down until I felt her sink onto me slowly, millimeter by millimeter, letting her cunt open around me. She squeezed me. She squeezed me as if she wanted to measure me before starting, those inner muscles closing around my dick.

—God —she said, eyes closed.— You’re bigger than you looked. You fit me just right.

She started moving. Slowly at first, a short sway, then rising and falling with her whole body, dropping her weight onto me, pulling almost all the way off before spearing herself back down to the hilt. I grabbed her waist and helped set the pace. The sofa creaked. Her tits bounced at my face level and I sucked on one nipple, then the other, nibbling them. The T-shirt of my pajamas clung to my chest with sweat. Carla bit her lip, leaned forward, kissed my neck, sank her teeth into my collarbone without leaving a mark, while the wet sound of her cunt taking my cock filled the living room.

***

We didn’t hear her come in.

When the apartment door opened for the second time that afternoon, Carla and I were in full motion, her on top, me gripping her hips hard, pushing her down each time she rose. I lifted my head and saw my sister standing in the doorway, her swimsuit still damp under a pair of shorts, a towel in her hand and her mouth slightly open.

Daniela. Light brown hair, straight, tied back in a ponytail. She’d always been taller than average, with wide hips and tits she hated and all her friends stared at. She was there, looking at us, staring at her best friend’s naked ass planted on her brother’s cock.

There was an absurd silence, the kind that lasts a second and feels like a minute.

Carla was the first to move. But she didn’t get off me. She stayed still on top of me, my cock still inside her, and looked at my sister without a hint of guilt.

—You’re back —she said.

—I’m back —Daniela answered, not moving from the doorway.

I didn’t understand anything. I wanted to speak and Carla squeezed my shoulder as if to say, “shut up.”

—Are you coming in or are you staying there? —she asked my sister.

Daniela closed the door behind her. She tossed the towel onto a chair. She walked slowly toward the sofa. I looked at her and found none of what I expected to see: neither shame, nor horror, nor reproach. I found something more like curiosity. Like anticipation.

When she reached the sofa, my sister leaned down and kissed Carla. On the mouth. Long, shameless, with tongue. The two of them kissed as if they’d done it a thousand times, sucking each other’s lips, eyes closed. After a while, Daniela pulled back and looked at me for the first time.

—You seriously thought I wasn’t going to find out? —she said, with a tiny smile.

I didn’t know what to answer.

—For months I’ve been telling Carla she should try you. I just didn’t dare.

I felt dizzy. Not from guilt, not from morals. From the sheer amount of information coming in all at once. Carla got up off me slowly, leaving my cock free, shining with her juices, and sat beside me, still naked. My sister stayed standing in front of us both.

—You choose —she told me.— If you want, I’ll leave and this stays between the two of you. If you want, I’ll stay.

I took a while to answer. Not because I wasn’t sure. I took a while because I had to hear myself say it out loud.

—Stay.

***

Daniela took off her swimsuit in two movements. Then her shorts. She was naked like Carla, her skin still marked from the bathing suit, a paler band around her tits and hips, her nipples pink and hardened by the air conditioner, her pubic mound with a neat shadow of hair. She knelt in front of the sofa, between my legs, just like Carla had a little while before.

She took my cock in her mouth without hesitation. She swallowed it halfway in one go and started moving up and down with a hunger I didn’t know she had, sucking me loudly, without caring that I was covered in her friend’s pussy juices. Carla settled beside her, grabbed her hair, and kept it out of the way so my sister could move without it covering her face, looking me in the eyes with a wicked smile.

—Suck it good, Dani —she murmured in her ear.— Take it all. You’ll see how good it tastes.

And Daniela obeyed. I heard her choke when she shoved me down her throat, she coughed, laughed with her mouth full, and went back down. I couldn’t look. I also couldn’t not look. I’d close my eyes for a second and open them, scared of missing something: my sister sucking my cock with hollow cheeks, Carla’s tongue licking her cheek and sliding down to meet mine at the tip of the glans.

Then they switched. Carla leaned over and ran her tongue over Daniela’s ear, down her neck, shoved it into my sister’s mouth all the way. The two of them kissed in between, traded spit, licked each other’s lips. And they came back to me, taking turns sucking me, sucking each other’s mouths with my dick in the middle, licking my balls at the same time, their tongues crossing over my skin.

At one point, Carla lay back on the sofa with her legs spread wide, showing her pink, open pussy, and my sister got into a four-point stance on the sofa, showing her white ass raised. I got behind Daniela, took my cock in one hand, and lined it up with my sister’s entrance. She was soaked. I pushed in slowly and watched her take me all at once, swallowing me without resistance, until my balls bumped against her.

—Ah, fuck —Daniela moaned, pressing her face against Carla’s thigh.

I grabbed her hips hard and started moving, pulling almost all the way out and then ramming back in. Her ass shook with each thrust, sending a wave up her back. While still taking me, she buried her face between Carla’s legs and started eating her pussy with the same hunger with which she’d sucked me off. Carla writhed on the sofa, grabbing my sister’s hair, pushing her face against her.

—That’s it, Dani, that’s it, don’t stop, lick me, lick me all over.

Carla moaned louder and louder, biting her hand. Daniela pressed her mouth against her so she wouldn’t scream and I felt her clench around my dick each time Carla jolted. I pushed harder, faster, not measuring anything, listening to the sloshing of my cock going in and out of my sister, the wet sound of Daniela’s mouth glued to her friend’s cunt.

—I’m going to cum —I warned through clenched teeth.

—Here —my sister said, and suddenly pulled away, leaving my cock in the air, and knelt beside Carla, who had already sat up.

The two of them arranged themselves in front of me at the edge of the sofa, like a mirror. One light blonde, one straight-haired brunette. They stuck out their tongues almost at the same time, together, tips touching, offering open mouths. I grabbed myself with my hand and started jerking my cock two inches from their faces. It didn’t take long. I shot the first rope with a rough groan and it hit Carla on the cheek, running to her lip. The second landed on my sister’s tongue, on her chin, on her breast. The rest split between the two of them, on their lips, on their chests, on their necks. I finished on top of them, smearing them with semen, my legs trembling.

Then they looked at each other and kissed again, laughing, licking each other’s smeared cheeks, sucking each other’s lips full of cum, licking their nipples clean between them. Carla gathered what had landed on her breast with two fingers and put it in my sister’s mouth, and Daniela sucked it off without taking her eyes off her.

I sank back into the sofa. My voice wouldn’t come. My legs were weak, my pulse racing, my cock still hard and dripping. I watched them laugh, get up, walk naked to the bathroom as if this were the most natural thing in the world, with semen dripping down their chests.

—Shower —Carla ordered from the hallway.

When they came back, wearing T-shirts borrowed from me and with wet hair, we didn’t talk about it. We made coffee. We put on a series. At nine my parents came back from the country and nobody suspected a thing.

Another week passed before it happened again. That time it was Daniela who offered first, without needing Carla to show up at the door. But that’s another story.
