Next Part ➡️

The house felt lonely without Rosé in it. The loud squeals don't enter my room without her voice being around; the stomps of her feet don't echo around the house without her being here; and the space doesn't feel occupied without her presence.

She's at her senior prom tonight, and I am incredibly proud of her for getting this far and doing so well in school. She truly deserves a good night to let her hair down and party like she wants to.

But there's always a part of me that wishes she'd spend more time around the house.

She's a joy to be around, her energy always picks me up, her light brightens even the darkest days and I just can't help but think about what happens when she decides to leave.

It didn't help that when I saw her walk down the stairs in her prom dress tonight.

Her heels clicking down the marble steps while her elegant fingers trace the railing, my mind began to wander more than I'd like it to.

I feel ashamed that I looked at my baby sister that way; her dress hugging her hips like it did, her hair all curly, up and doing those small strands in front of her eyes.

Her perfect wide doe eyes so filled with happiness as her Chelsea grin grew wider the more attention was on her. It turned from appreciating Rosé's figure respectfully to then getting dirty thoughts about her.

When she was at the top of the stairs I saw up her skirt, she was wearing a pair of sexy pink laced panties that made my mind go wild.

I began to imagine her at the prom, drinking and dancing with her hips as her prom date (total loser btw) grinds up on her as she gets all hot and bothered.

She would then drag him by the cock and take him into a classroom, hike up her tight prom dress, and bounce back and forth on his dick over and over and over again, milking him for all he's worth.

But he would never make her cum. He's a total loser and has no idea how to make a woman cum.

She would then pull her panties up from her ankle and walk back on the dance floor with his cum dripping down her leg as she keeps dancing till night turns to day.

I shake my head in shame and wake back up to reality. That's my fucking sister, stepsister but still my sister, I've known her for well over 10 years and it's wrong.

She left 4 hours ago and yet my cock is still rock hard. I'm ashamed about these dirty rotten thoughts but I can't help it when she looked so good tonight.

I try to get rid of my cock by watching porn and jerking off but nothing seems to work, I just couldn't get off despite trying my hardest. I texted my girlfriend Jennie to see if she would come over and fuck but she's busy. I even tried masturbating to Rosie's friend Lisa, she shakes her ass and dances slutily on TikTok all the time but still I couldn't finish.

I tried to get as close to cumming as possible and when looking over my girlfriend's nudes she sent over and Lisa's TikTok I almost got there but then there was a knock at my door.

Knock! Knock! Knock!

I rapidly pull my boxers back up and try to cover up but the door opens.

It's Rosé.

Fuck.

"Hey, you're still up," she says softly.

"It's only midnight." I laugh, trying to put my hands over my cock to hide it.

"True," she laughs to herself. "Can I come in?"

My heart is beating so fast right now. I don't think that would be such a good idea because it would be so embarrassing if she saw my rock hard cock through my boxers and assumed it was because of her.

She'd be right but she doesn't need to know that.

Then again I don't want to be a dick and turn her away after having what I can assume was the night of her life.

"Uh yeah sure come in please," I stammer. Dumbass.

"So how was your night?" I ask trying to take my mind off of... Everything.

"Oh my God it was amazing! When we got there we started taking pictures and saying goodbye to our teachers. It was all so much fun!" Rosie cheered.

Her playful side coming out as she slaps the bed and even my thigh for 2 seconds before pulling it away. My cock has never been harder. Fuck she's making it harder for me to concentrate here.

I clench a fist in my bedsheets as she continues her story.

"Then when more people showed up we started dancing and having funnn~" She slurred that time. Is she drunk?

"You had some stuff to drink Rosie?" I ask.

"Me? Noooo. I would never~" She replies, clearly slurring her words this time and her hands waving all over the place again, her finger nails scraping lightly across my thigh.

"Well maybe just a little." She giggles measuring with her fingers. "But anyway, we were dancing and I had Tae come up and we started dancing together it was so much fun!"

I took a deep breath in to try and compose myself yet again.

"What's with you? You're being so boring!" Rosie said hitting me lightly.

"No I'm not I'm just-listening," I tell her.

"No you're just being boring. A boring old man." Rosie teases.

"Old man? I'm 2 years older than you."

"An old man is an old man."

"Crack a smile old man," Rosie teases again as she starts to tickle me.

"No. Rosie you know I hate that." I tell her.

"I know. Maybe it'll get you to stop being grumpy." Rosie replies, jumping onto my lap and starts tickling me with her fingernails. Her fingernails are worse than anything because they're so light when she touches me.

"Rosie no! No!" I exclaim trying to stop her, but she's surprisingly strong for a woman so petite.

"Come on crack a smile!" Rosie laughs tickling my sides and then going under my arms. Her hips grinding on me but I can't feel anything as the sensation, no the torture of her tickling me overpowers that.

"Please stop!" I laugh trying to grab her wrists but she wriggles out last minute and makes it worse on me. I try bucking my hips at her to get her off but she plants her ass back down on my lap and continues to tickle me.

"There's the smile!" Rosie giggles as she continues her onslaught. I buck my hips one final time to get her off, but when she stops me and plants herself back down...

"Ahh!" She moans.

Everything stops in that moment. Her hands no longer try to tickle me; instead they end up in the air in shock. Our bodies stay as absolutely still as they could as we both try to process what just happened.

My cock is inside my little sister.

"Is-Is that your dick?" She speaks breathlessly. Her big doe eyes as wide as they can be, and now I know where the saying like a deer in headlights comes from.

"I-I didn't-I didn't mean to-" I stutter. I have no words for what just happened and I ramble trying to save the situation but nothing useful comes out.

Every small move we make just makes it worse as whenever we try to shift our weight anywhere we feel each other even more intensely.

"I'm just gonna try to get off okay?" Rosie breathes, she places her hands on my chest and slowly brings her hips up. The feeling is like no other.

I've never felt anyone as tight, or as wet as Rosie is right now and as she brings her hips up her hand slips and her weight is transfered back down onto my lap.

"Ahh!" She moans again, her hand quickly covering her mouth to shut herself up.

"What was that?" Mom yelled from down the hall. Our eyes pop out of our heads as we stare at each other like we just murdered someone.

"Say something." Rosie whispers.

"What do I say?"

"I don't know just say something!" She quietly screams.

"Sorry mom that was just-" I pause as I look at Rosie deep in her eyes as I can feel her squeezing tighter around me. Fuck. "-We were just play fighting!"

The longest silence ever followed. It was like we were waiting for the bullets to kill us and let us get away from whatever bullshit either of us were trying not to do right now.

"Just quiet down! Some of us are trying to sleep!" Mom yells.

"Okay sorry Mom!" Rosie answers.

"What the fuck excuse was that?" She turns back to me.

"I didn't see you coming up with anything!"

"Well I'm a little preocupied at the moment what with your dick inside me!" She raises her voice slightly so I have to use my hand to cover her mouth.

"Not so loud!" I tell her, but as I do I have to clench my abs and hunch over a bit. She tightened up when I did that.

"What the hell was that?" I ask her. She swats my hand away and crosses her arms just under her boobs making them look bigger and perkier. That makes my cock twitch at the sight.

She then looks down and is extremely confused.

"What the hell was that?" She asks me back.

"Let's just try and get out of this situation shall we?" I ask trying to steer away from the iceberg.

"Yeah okay let me just..." Rosie slowly lifts her hips again but something pulls her back down again and the feeling of her tight pussy clasps around the base of my manhood once again.

"Oh fuck." I moan this time as my hands clasp the side of my head trying not to just grab her hips right now and move her up and down on my shaft.

"Just shut the fuck up." Rosie covers my mouth this time, as she does she leans forward and stimulates us both as she does so.

She moves back down and instead of trying to get off my lap she moves up and down, her hands running through her own hair as she begins to ride me.

"What the fuck are you doing?" I ask, flabbergasted that she's riding me.

"It's so wrong." Rosie moans lightly. "But if I just get off it's not that wrong right?" She justifies.

Her pussy wrapping around my cock like wood in a vice, her juices leaking down my cock like her pussy is drooling on it.

"Oh fuck Rosie." I moan, my hands hesitating to move to her hips.

"Just be quiet for a sec while I get off, then it's over okay?" Rosie justifies again.

Her hips moved like a trained dancer, the way they glide up and down, up and down, up and down, it was hypnotising. Her mouth opened up as she moaned, her noises getting slightly louder and louder as she did so.

"Oh fuck yes!" She moaned, her hips moving faster now. "If one of us has a post-nut clarity then it'll be okay. We can go back to being brother and sister like nothing ever happened."

She's clearly chasing her climax as she abandons all requisite silence and let loose.

"You're so big inside me fuck! You're stretching me so good mhm~"

Her hands move down to her pink panties as she slides her hands inside the waistline and rubs her clit rapidly.

"Pink panties? You're such a slut~" I moan finally putting my hands around her waist as she rides me into oblivion.

"Shut up. No I'm not," Rosie moans, her opposition clearly fake as her pussy got tighter as I said that.

"Really? Because you moaned louder and got tighter when I called you a slut."

"No I didn't~" Rosie moans again, her grip getting more snug and her hair getting tugged on more and more.

"My little sister wearing pink panties and getting so wet for her big brother. You're such a dirty slut." I tease.

"Oh fuck yes~" She moans "keep going!"

"I knew you liked being degraded, a petite little slut with a tight little pussy riding my big dick as you get yourself off. Selfish little whore."

"Fuck I'm so close~" Rosie moans, her eyes rolling back into her head as she loses control of herself, her hips moving at the speed of light as her pussy clamps down.

I move her hand away from her clit and replace it with mine, rubbing that precious love button until I can see it on her face and feel it on my cock; she's gonna cum. And so am I.

The way her face contorts in pleasure and her eyes rolling back in her head is sot hot that I'm trying my best not to cum until she does but I can't hold it for much longer.

"Oh my God~" She screams and shudders. Her face goes red as her body keels over and into my chest. Her noises getting way too loud for us to be keeping whatever this is a secret so I cover her mouth and hold on tight as she screams into my hand while cumming her brains out.

Her pussy clamping down on my dick makes me loose all control and I also shake with pleasure as her warmth milks me dry.

It feels so wrong to be cumming inside my sister but I have a feeling that she likes it as she cums again in quick succession. She lays there on my chest, just for a minute until she composes herself and once she does she leans back upright and stares down at me.

Her hair sticking to the sides of her face and she blinks her eyes open again.

"Did you just? Did you just cum in me?" She asks feeling her lips.

"What did I say about being quiet?!" Mom barges in.

Me and my sister freeze. My face is mortified, and Rosie daren't turn around as she stares me dead in the face. Do something. She mouths, her eyes showing she's just as scared as me.

I peer out from behind Rosie.

"Sorry mom, won't happen again I promise. Rosie was just going to bed anyways," I lie. Mom's face is angry but when she sees her two kids ‘chilling’ in her oldest’s room, she softens and nods.

"Don’t let me hear you again," she warns, closing the door with a click. Rosie sighs a sigh of relief and jumps off my cock like it was that easy in the first place.

"What are you doing?" I ask, my cock feeling cold now it's no longer warmed by her core.

"That was a mistake. We shouldn't have done that, I'm going to bed. Goodnight," Rosie says and runs out the door, her heels clicking and clacking down the hall and the door to her room slams shut.
