What My Sister Saw in My Room That Night

I always say I’m shy and people believe me. Modesty is my best disguise: the look of someone who wouldn’t hurt a fly, the soft voice, the eyes that look down at the floor when someone says something dirty. What no one knows is that my body doesn’t understand manners or closed doors. I have a hunger that doesn’t keep hours and a cunt that gets wet for any excuse.

And there’s only one thing that turns me on more than any caress: the possibility of being caught with my panties around my ankles and a cock inside me.

It’s not that I want to be seen, or at least that’s what I told myself for a long time. It’s the edge. That second when any noise in the hallway chills your spine and, instead of stopping you, pushes you to spread your hips wider. A spark that turns any ordinary hookup into something electric, out of control, impossible to stop.

I discovered it almost by accident. The first time was in the bathroom of a packed bar, with the music thudding through the other side of a door that didn’t shut properly. Anyone could have walked in. That night I understood it wasn’t the place that turned me on, but the risk. The idea that some stranger’s hand would turn the knob at the exact moment another stranger was burying himself deep inside me.

Since then I learned to hide it. To keep a blank face at family lunches, to fake a blush when someone told a dirty joke. Inside, meanwhile, I was calculating. Measuring distances, noises, schedules. Looking for the edge in every place I entered, like someone looking for an emergency exit, except I was looking for the opposite.

I’m twenty-two and, like almost everyone at university, I still live with my parents. That night was supposed to be a quiet visit from my boyfriend. Bruno had come over under the excuse of studying for an exam, and my folks let him go upstairs with the usual condition.

—Leave the door open —my mom said from the kitchen, without looking up.

Wide open. As if that guaranteed anything.

The air in my room felt heavy that night. My parents were asleep one floor below and my sister Caro was resting in the room next door, separated from me by a thin wall and a door that led into the same hallway. The darkness outside mixed with the bluish glow of my monitor, the only light left on.

Bruno was sitting in my chair, that worn leather armchair I’d bought with my first paycheck and that knew all my secrets. I was straddling him, feeling his cock harden against the fabric of my underwear. Black lace, already soaked through with my own juices before he even touched me. I rubbed slowly against the bulge, moving my hips in circles, noticing how his pants were getting stained with my wetness and how he clenched his teeth to keep from moaning.

I got up. I walked to the bathroom with my thighs burning and, when I came back, the garment was no longer on my body. I had dropped it somewhere in the hallway on purpose.

—Close your eyes —I ordered in a whisper that was anything but shy.

I passed the wet fabric under his nose, slowly, letting the scent of my soaked cunt hand him over to me before my hands did. Bruno took a deep breath and let out a low sound he had to swallow. My fingers were already unbuttoning his pants and pulling his briefs down until his cock was free, hard, thick, the tip already shining with pre-cum.

I knelt between his legs. Before touching him, I brought my own lingerie to my mouth and tasted it in front of him, sucking the soaked fabric, looking him right in the eyes. I wanted him to understand how far I was willing to go. Then I lowered my head.

I ran my tongue over the whole length of him, from the balls to the tip, slowly, smearing the head with my spit. I kissed the crown wetly, wrapped my lips around it, and took him in all at once, swallowing him down until my nose hit his pubic bone. He shuddered and I had to squeeze his thighs with my hands so he wouldn’t cry out.

The blowjob was savage. I wasn’t trying to make him finish fast; I was trying to make him suffer. To make him bite his lips to keep quiet while I swallowed him whole, unhurried, measuring every movement by the silence in the house. I bobbed up and down on him, letting a thread of saliva drip over his balls, and every so often I pulled off completely and spit on him so he’d slip in and out better. Every time something creaked in the hallway, instead of stopping, I clamped down harder with my throat, feeling his cock throb inside my mouth.

I licked his balls one by one while I kept jerking him with my hand, now slick with my spit. He had his head thrown back, the vein in his neck standing out, his hands balled into fists on the armrests so he wouldn’t moan.

I took off my T-shirt. I wasn’t wearing a bra. I let the monitor light draw my curves and my standing tits while I climbed onto him again. I grabbed his cock with my hand, guided it to my opening, and drove it in all at once, all the way to the hilt, feeling my cunt open around that hardness I already knew by heart. I let out a muffled gasp and held still for a second, squeezing him inside me, savoring the way he filled me.

I started moving. Up and down, hands on his shoulders, feeling his cock slide in and out with a sticky little smack each time. The wet, rhythmic, obscene sound filled the room and bounced off the walls. I took his hand and put it on one tit so he’d pinch my nipple while I rode him. I was in a full trance, eyes closed, breath in tatters, when Bruno dug his nails into my waist.

—Stop —he said in a thread of a voice—. Stop. Caro’s at the door.

The cold dropped down my spine like ice water.

There she was. In the doorway, in her nightgown, with her hand still on the frame. My sister, watching the supposedly shy one in the family devour her boyfriend in the dark, buried to the hilt, tits out and thighs shining with juice. She said nothing. I didn’t either. We both froze for one eternal second, with Bruno’s cock still buried inside me.

And what I felt wasn’t shame.

The thrill of being caught hit me like an electric shock that ran from my clit to the nape of my neck. I had to dig my nails into the back of the chair so I wouldn’t come right then and there, with her watching me. Caro narrowed her eyes, turned around, and closed her door without a single comment.

Bruno asked me, breathing hard, if I wanted to stop. I covered his mouth with my hand and kept moving. Slower. Deeper. Going all the way down and staying there, grinding my clit against his pubic bone, knowing there was someone on the other side of that wall who now knew my real face. I leaned forward so my tits brushed his mouth and he sucked one nipple, then the other, while I kept circling my ass, squeezing him inside me with every thrust.

I felt him get even harder. He grabbed my hips and started driving up into me from below, silently, fucking me with short, hard thrusts that stole my breath. My orgasm rushed up all at once, uncontrollable, and when I exploded I had to bite the pillow I’d thrown over the backrest so I wouldn’t scream, my cunt clamping down on him in waves. He spilled inside me a second later, biting my shoulder to keep quiet, filling me with hot semen that ran down my thighs when I stood up.

I thought that night had been an accident. One of those things that happen once and don’t repeat. I was wrong. Because ever since then, every time I was with Bruno, my head went back to the doorway, to the silhouette of my sister, to the edge of being seen. And I needed it again.

Danger, I discovered, is addictive. Once you try it, everything else tastes flat.

A few weeks later, the setting changed. We had an hour free between two classes and the university was half empty. I took Bruno by the hand and dragged him toward the basement stairs, that part of the building where they store old chairs and broken projectors. Cold, dusty, forbidden. Perfect.

There was no preamble. I shoved him against a damp wall, unbuckled his belt, and yanked his pants and briefs down in one pull. He was already half hard, and with two strokes of my hand he went rock-hard. I knelt on the concrete floor, not caring about the cold on my knees or the dirt on my clothes. The tip bumped my lips and I stuck out my tongue to lick him from below, looking him in the eye.

The athletic pants were in my way, so I pulled them down to my knees and shoved one hand straight between my legs while my mouth sealed his fate. I was soaked. My fingers sank into my cunt without resistance, dripping, and I started rubbing my clit in furious circles while I swallowed him whole.

I took him down my throat and held him there, not breathing, until tears spilled out of my eyes and spit ran down my chin. I pulled off him suddenly with a wet sound, gasped, and shoved him back into my mouth again. Bruno grabbed the back of my neck and started moving my head for me, setting the rhythm, fucking my mouth with short thrusts that made me choke.

I was masturbating furiously, listening for any echo of footsteps on the stairs. My fingers were coated in my own thick, warm slick, a string hanging between my hand and my cunt, and I brought them up to Bruno’s face.

—Lick —I ordered, marking him as mine.

He obeyed without hesitation, eyes locked on mine, sucking my fingers one by one, tasting how wet I was for him. That drove me to the edge. I lowered my head again, hungry, taking him whole once more, while with my other hand I squeezed his swollen balls. I could feel them tense, ready to burst.

—I’m gonna come —he growled, his eyes rolling back.

I stuck out my tongue. I didn’t move out of the way. I grabbed him with my hand and shook him over my open mouth. I took the first burst on my tongue, hot and thick, and the next ones splattered my chin, my lips, my cheeks. A stream landed on my chin and ran down my neck. I stayed there for a second, kneeling in that filthy corner, face covered in semen, sticking out my tongue to gather what had escaped me and swallowing it slowly, savoring the end of my hunt. I slid two fingers into my mouth along with the tip of his cock, sucking the last drop out of him.

And then, the door slammed.

The back door crashed shut against the wall, a metallic echo that yanked me back to reality. Someone had been there. Someone had seen the quiet girl in the front row swallow the last drop in the basement, smeared and kneeling, with my hand still buried in my cunt.

I wiped myself with the back of my hand, licked my fingers, pulled my pants up, and we ran up the stairs almost at a sprint, hearts in our throats, not daring to look at who it had been. Bruno was pale. Inside, I was burning and my face was still sticky.

The fear that it would get out lasted until midnight.

I was in bed, replaying that door sound over and over with my hand between my legs, when my phone lit up. A message from Vera, my best friend, the only person I know who has class at that hour in that hallway.

“You’re so greedy. You can’t even wait to get home.”

I stared at the message for a long time. I waited to feel shame, panic, the urge to delete the conversation and die. None of that came.

What came was something else. Knowing Vera had seen me at my most animal, on my knees, covered in come, with not a trace of the good girl everyone thinks I am, didn’t scare me. It gave me an idea. I pinched a nipple through my shirt and felt my cunt twitch hard.

Because one thing is almost getting caught. And something very different is knowing someone saw you and, instead of judging you, texted you at midnight with that smile between the lines.

After a long while, I answered, my thumb hesitating over the keyboard.

“And what were you doing watching so closely?”

I watched the three dots appear and disappear several times. It took her a while to answer. When she did, it was just one word, and I kept staring at it until I fell asleep with the phone in one hand and the other still buried between my thighs, squeezing my clit.

“Learning.”

I turned off the screen and laughed alone in the dark. The shy one in the family. The quiet girl in the front row. If they only knew.

Now that someone else knows my secret, the game is just beginning. And for the first time I’m not afraid of what comes next. I’m restless in a way I don’t know how I’m going to endure until the next class, with my cunt throbbing and my fingers already searching again.
