My Sister’s Sleepover Ended With Me on My Knees

I moved back home with my parents after spending a couple of years living with my uncle, just as I finished university. By then, my mother had imposed a new rule that completely changed life under that roof: the men in the house had to go around naked, and we were strictly forbidden to have an erection. If anyone was caught aroused, the punishment was immediate and anything but pleasant.

The first and only time it happened to me in front of my sister Marina, she ran to tell my mother, who calmly gave her permission to punish me. The kick Marina landed on me doubled me over and left me sprawled on the floor for several minutes. The worst part wasn’t the pain, but the smile she wore while doing it. My mother watched from the side, more serious, but with a glint in her eyes that gave away that she was enjoying the scene too.

—You should thank me it was me and not her —Marina told me that day, rubbing her knuckles—. Hers are devastating. Once she gave Dad one and he passed out from the pain.

I learned fast to avoid her. Marina used to walk around the house in tiny clothes, and I did everything possible not to run into her, in case my body betrayed me again.

***

That afternoon, my sister had invited a group of friends to sleep over. They were all her age, around twenty, and from the screams and laughter rising from downstairs I figured they had already started having fun. I went down for a glass of water and, when I reached the bottom of the stairs, I came upon a scene that froze my blood.

My father was kneeling in the living room, his hands crossed behind his back, and Marina was standing in front of him. Before I could react, she unleashed a brutal kick on him, much harder than the one she had given me. I don’t know how he took it. My father let out a muffled groan and collapsed onto his side, curled in on himself. Marina was smiling, satisfied.

—What happened? —I asked, still on the last step.

—That pervert got hard watching the weather girl —she replied, pointing at the television.

I turned my head. Sure enough, there was a presenter in a ridiculously short dress giving the forecast. Maybe she’d find it funny to know it cost my father a kick, I thought.

—Weren’t you too hard on him?

—Maybe... —she said with feigned calm—. From now on I’ll save all my strength for you, little brother.

—And what did I do?

—Dad’s already trained. You still need to be broken in with kicks. And my friends are coming over tonight, so it’ll be a perfect night.

—Great —I replied with all the sarcasm I could muster, and went back upstairs with my water without bothering to help my father.

***

I locked myself in my room with my headphones on, determined not to go downstairs under any circumstances. The idea of a group of strangers seeing me naked terrified me. For a while it worked: the music covered the noise from below. But at some point I heard footsteps on the stairs and, right after, an odd silence. I took one headphone off.

My bedroom door flew open. Marina was in the doorway, and behind her, packed together, all her friends. She was showing me off like a trophy. A chorus of laughter burst out while I covered myself with frantic hands.

—Meet my brother, Adrián —Marina said between laughs—. Say hello.

—You were right, it’s tiny —blurted out a blonde girl, and the others cracked up.

I felt every pair of eyes nailed to me. Humiliation climbed my neck like a burn. When the mockery became unbearable, I jumped up and moved toward the door to shut it.

—Careful, he’s coming to give us what for! —another girl laughed.

I shoved to get them out into the hallway. As I did, one of them, a brunette with a mischievous look, struck my groin with the back of her hand. The pain was so sharp that I doubled over, but I kept pushing until I got them out and shut the door. For the first time, I locked it, even though I knew that was forbidden.

—I got the little guy! —the brunette yelled from the other side—. I could feel it all the way to the balls!

—You’re awful, Dafne —another one said, dying of laughter.

I heard them try the handle without success and, little by little, move away toward Marina’s room. I sat down against the door, clutching my aching cock, trying to catch my breath.

***

Ten minutes later, someone knocked.

—Who is it?

—It’s me, Adrián.

My mother’s voice made my skin prickle. I thought she was out with her friends until late. I sprang up to undo the lock and opened the door. There she was, imposing, and beside her all of Marina’s friends with tightly held smiles.

—What’s going on? —I asked.

—Come here —she said, and took my cock with her fingertips to drag me out of the room. The girls stifled a few giggles, but they fell silent in my mother’s presence.

—Ouch... what did I do? —I protested.

—You know you’re forbidden to lock the door.

—Yes, but Marina and her friends came in to bother me.

—We just wanted to say hello, ma’am —one of them chimed in in an innocent voice—. Dafne commented that he had a small one and he got offended.

I covered myself on reflex. My mother slapped my hand away.

—Don’t cover yourself, Adrián. Were you bothered because they said you have a small one? The thing is, you do have a small one! —None of them could hold back their laughter.

—One of them hit me in the balls —I said, my voice on the verge of cracking.

—Sorry, ma’am, it was me —Dafne admitted without losing her smile—. I thought he was going to hit us.

—She’s lying! I was only going to close the door —I shot back.

—Silence! —The hallway went dead quiet—. Adrián, I don’t care about your reasons. You locked the door and that deserves punishment.

A chill ran down my back. Marina’s friends opened their eyes wide; it was obvious my sister had already told them what the punishments in this house consisted of, and they were dying to witness one.

—Mom, I didn’t do anything wrong, they were bothering me.

—I’ll give you two options —she said, unyielding—. Either you’re nice to your sister and her friends for the rest of the night, or I punish you right here, in front of everyone. Choose.

—I’ll be nice —I replied at once. The situation was unfair, but I couldn’t even imagine one of her kicks in front of those girls.

—Very good. I want you to wait on them, ask them what they need every fifteen minutes, and stop being rude.

—Why do I have to be their servant?

—You won’t be their servant. You’ll just be nice.

—Thanks, Mommy —Marina sang out with a sweetness so fake it made my stomach turn—. Little brother, let’s get along, okay?

***

I went down to the kitchen reluctantly to make the lemonade the first one “needed.” I was tempted to spit in the pitcher, but the risk wasn’t worth it. I came back upstairs with five glasses and entered Marina’s room. As unbearable as they were, I couldn’t help noticing they were all gorgeous: long legs peeking out from tiny shorts, sharp smiles, freshly washed hair. They were sitting in a circle on the floor.

I set the pitcher on a table and made to leave.

—Aren’t you going to serve us, little brother? —Marina asked.

—I brought it for you already.

—Mom said to be nice. That’s not nice.

I clenched my teeth and served each glass, avoiding their eyes.

—Thanks, Adrián. Marina’s lucky to have you.

—You’re welcome —I muttered.

—I like your little thing, it’s small but cute —another one teased, and they all burst out laughing again.

—Don’t leave yet —said the blonde when I tried to escape—. We’re going to play truth or dare. If you play five rounds, we’ll leave you alone.

—You promise?

—Yes —they answered in chorus.

I agreed. And, though it cost me to admit it, being surrounded by so many pretty girls in shorts had something intoxicating about it, even with my pride in the dirt.

***

Marina spun the bottle. It landed on Camila, the prettiest one of all in my opinion. She wasn’t as skinny as the others, but she had curves that took your breath away and, above all, a sweet, shy face. She was the only one who hadn’t insulted me all night.

—Camila, truth or dare? —my sister asked.

—Truth —she replied softly.

—Coward! —Dafne complained.

—She picked truth, end of story. Tell us, Camila, what do you think of Adrián’s cock?

My blood froze again. I slowly brought my hands to my groin while Camila turned red all the way to her ears.

—Well... it’s fine, I guess —she said in a small voice.

—Boo! Answer properly. Does it seem big to you, small? Do you like it? —Dafne pressed, delighted to make her suffer.

—Come on, be honest. Pretend my brother isn’t here —Marina asked.

—Okay... I guess it is a little small —she finally blurted out, her face burning.

The room exploded in laughter. I wanted the ground to swallow me. The worst part was that she hadn’t said it to mock me: she’d said it seriously, forced into it, and that hurt more than all the jokes together.

—Sorry, Adrián —she told me with a guilty expression.

—It’s fine —I lied.

—And you still like it? —Marina pushed again.

Camila took a while to answer.

—I think so... it’s cute even if it isn’t big.

The laughter returned, but something strange happened to me: I started to like this girl who answered with so much embarrassment and so much honesty. Too bad that, after tonight, she’d never be able to look at me any other way.

***

The bottle spun again and landed on Dafne, the brunette.

—Truth or dare?

—Truth.

—Would you fuck my brother? —Marina asked, and another round of laughter filled the room.

—Are all the questions going to be about me? —I protested.

—Relax, this is the last one about you —Marina said.

—No, not in a million years —Dafne replied cruelly—. I need men with real dicks, the kind that split you in two. With Adrián’s, I wouldn’t even feel it inside my pussy. I need it shoved all the way in, hitting my womb, and that little thing doesn’t even get there.

While they all laughed, I caught Camila pressing her lips together to keep from doing so. That small difference comforted me a little.

The bottle spun again and, once more, pointed at Camila.

—You again. This time pick dare, so things get interesting.

—What if the dare is really awful? —she hesitated.

—Don’t be a coward.

—Okay... dare.

—Great! You’re going to stay in your underwear and go into the closet with Adrián for ten minutes —Marina announced, and the room erupted.

Camila turned bright red. I was angry that my sister was putting her in that position.

—I can’t do that —Camila protested.

—It’s your dare, you have to do it! —Renata, the brunette, pressured her.

—But I’m embarrassed for Adrián to see me in my underwear...

—You saw his cock all night! Let him see your tits —Dafne finished, laughing.

I decided to help her out.

—Let’s get this over with. I promise I won’t do anything —I told her, to calm her down.

***

Camila stood up, pulled down her shorts, and took off her loose T-shirt. I had to look away not to betray myself: she had an amazing body, wide hips, huge breasts that barely fit in her white bra, and skin that begged to be touched. Her white panties clung to her cunt, outlining every fold. We walked to the closet and my sister closed the door behind us.

—At least give her a kiss, don’t be boring —Marina laughed before leaving us in the dark.

The space was tiny. I could barely make out her silhouette. The others’ laughter seeped through the wood and was the only thing easing the awkward silence between us.

—Do you want to sit down? —I asked.

—Yes —she answered in a thread of a voice.

We managed to settle on the floor, so tightly pressed together that our legs ended up touching. I couldn’t think of anything to say. Then, without warning, I felt her hand on my thigh. My breath caught. Her hand moved slowly upward, caressing me, until her fingertips brushed the base of my cock, which was already starting to wake up. A gasp slipped out of me.

—Shhh... —she whispered, and kissed me.

I answered by opening her mouth with my tongue. She tasted sweet, like the lemonade I myself had served. I put my hand on her bare thigh and slid it up to her hip. Her skin was warm, soft, and every inch I covered made her tremble. I slid my hand over her bra and squeezed one breast. It was heavy, soft, spilling between my fingers. I pinched her nipple through the fabric and she moaned into my mouth.

Meanwhile, her hand had closed around my already hard cock. She began to jerk me slowly, squeezing from top to bottom, exposing the head and pulling the skin back down with a rhythm that made me grit my teeth not to cry out.

—Still think it’s small? —I asked, half joking, my voice shaking.

—Yes... —she answered, and I almost died—. But I like it the way it is. It fits entirely in my hand and that way I can squeeze it all. I like you, Adrián.

Those words revived me. I slid one bra strap down and freed one breast. In the dimness it was barely visible, but I could feel it, round and heavy, the nipple already hard and pointing at me. I leaned down and put it in my mouth. I sucked the whole thing, tugging at the nipple with my lips, nibbling it carefully, while she arched against me and squeezed my cock harder.

—God... —she panted softly—. Don’t stop.

I switched to the other breast and did the same. She jerked me faster and faster, her wrist twisting at the tip, spreading the liquid already leaking out of me so her hand would slide better. I moved my hand down her stomach to her panties and found them soaked. I slipped my fingers under the elastic and touched her cunt directly. She was drenched, so slick my fingers sank in without resistance.

—Oh, Adrián... —she moaned under her breath, biting her lip so the girls outside wouldn’t hear her.

I opened her cunt lips with my fingers and started rubbing her clit in circles, first gentle, then faster. She spread her legs as far as the closet allowed and I slid two fingers inside her. She was so tight and so hot it blurred my vision. I closed my eyes and started pumping her, in and out with my fingers while my thumb kept working her clit.

Camila squeezed my cock in time with my fingers, muffling her moans against my shoulder. Her hips moved on their own, riding my hand, searching for more. I was on the verge of blowing. I bit her neck, licked her earlobe, and whispered in her ear:

—Come for me, Camila. Come on my fingers.

It was like pressing a button. I felt her pussy clamp down around my fingers in spasms, her whole body tensing and then going limp, and she buried her face in my neck so she wouldn’t scream. At the same time, the hand that was jerking me squeezed hard and pumped faster. I couldn’t take even three more strokes: I came in thick spurts onto her hand, onto my own stomach, an orgasm so long and filthy I thought I was going to faint in the closet.

We stayed wrapped around each other in the dark, breathing silently, her still-sticky fingers gripping my slick cock and my fingers still buried in her soaked cunt. I gave her one last kiss on the lips, long and slow, while outside the others kept laughing, unaware of what had just happened.

And then the door flew open and the light blinded us.

***

Marina froze when she saw us so close together, with her hand still where it shouldn’t have been and Camila’s bra with one strap fallen down. We sprang apart and the others went wild.

—Did you suck my brother off? —Marina asked.

—No, we were just talking —Camila lied, hiding the hand full of semen behind her back.

—Look at your hand —Renata said, yanking it from her and lifting it up for everyone to see the strands of cum hanging between her fingers—. Besides small, she’s precocious. She came from a badly handled wank.

Camila went red, but the others, instead of continuing to mock her, started congratulating her for having “completed the dare.” Dafne took her hand and, to everyone else’s scandal, licked one finger covered in my semen.

—Mmm... tastes like little, just like the rest of him —she blurted, and everyone died laughing.

We came out of the closet and Marina cut me off with a smile I already knew far too well.

—With you it’s different, Adrián. Mom has forbidden you from getting hard. Imagine what she’ll do when she finds out you came in my friend’s hand, inside my closet.

I swallowed.

—You forced me to play, you put me in there. That’s not fair.

—I didn’t ask for your cock to get hard or for you to fill her hand with cum. That’s your responsibility.

—Don’t tell Mom. Please.

—Mmm... I haven’t decided yet. What do you say, girls? Do I tell her?

—Yes, tell her! —they chorused, laughing.

—Please, Marina —I begged.

—Kiss my feet and I’ll reconsider.

—Marina... I’m not doing that.

—Good. Your dignity is worth more than your balls. Respectable. Now I’m going back to Mom.

—Wait! —I grabbed her arm. I got down on my knees. She put one foot forward and I kissed it, utterly humiliated, not daring to look at Camila.

—You convinced me, Adrián. We’ll keep your little secret... but in exchange you’ll be our slave every time we get together.

—Yes! —they all cheered.

—You’re crazy —I muttered.

—A little. But it’ll be a lot more fun than watching Mom castrate you in the yard.

I was against the wall and I knew it. I agreed. While the girls hugged each other in a frenzy, I searched for Camila with my eyes. She wasn’t shouting like the others, but on her lips there was a small, almost tender smile, and her fingers, still sticky with my semen, were slowly rubbing against each other as if she didn’t want to clean it off. It seemed that, in her shy way, she was enjoying my humiliation too.

And the strangest thing of all was that, even so, I couldn’t stop wanting her. I had no idea what Marina and her friends were planning to do with me from then on, but something told me that night had only been the beginning.
