Making my sister pay for ruining my day

I am Andy, and I was not having the best of days. Last night I couldn’t get any sleep because my bratty stupid little sister, Kirsty, who’s 18, had been shagging some lad for most of the night. All I could hear were the constant squeaking of her bed springs and loud moans rippling through the thin walls of their house. I did eventually drift off at 4 am, but then my fucking alarm woke him up at 6:30 am. To top it off, having a full day of classes at college and then an afternoon shift at work with no coffee and one breakfast sandwich was terrible. The bus coming late was worse. What else could go fucking wrong?

The only thing on his mind was getting my car back from Kirsty and going out to see his girlfriend later that night. I wasn’t going to pay the bus fair for the third time today for a late-night booty call, and I sure wasn’t going to stay another night with my sister and me in the house.

Walking up the hill to my parents’ house from the stop, I noticed my car awkwardly in front of the garage door. As I got closer, I noticed that the mirror on the left side, the door, and the headlight were completely shattered.

The paint job was scratched, grey, and battered. I nearly fell to my knees at the sight of my fucking car that I worked for as a banged-up mess. I barged into the house, flinging my keys and backpack on the floor.

“Kirsty!” I was angry as I shouted up the stairs.

“Kirsty! Get the fuck down here!” I shouted again. I was so angry.

“Alright! For fuck sake, bro, Wait for a second!” Kirsty shouted down.

I heard the pitter-patter of her bare feet against the wooden steps. She was wearing a loose white plain short shirt barely covering her tits as I could see the underboob and tight black leggings that were skin tight and clung to her lower body like a second skin. Despite being filled with rage, I noticed her nipples poking through her shirt and her visible pussy lips tightly packed cameltoe. I brought my eyes up to hers and cleared my head.

“Kirsty, listen, I’m going to ask you this one time. What the fuck did you do to my car?” I said through shaky breaths.

Kirsty let out a bored groan and stopped at the bottom of the steps looking shifty as fuck.

“I was reversing out of the parking garage at the movie theatre near that old bar, and I got too close to some other driver. I am sorry.” She explained while casually brushing her dirty blonde hair out of her face. I stared at her, waiting for a better explanation or a sorry. Nothing. Fucking nothing, just like the brat she is, Jesus.

“Didn’t you at least leave a note?” I asked her, still my blood boiling.

“Nope. Look, it was an accident; I’ll pay you back.” She was sitting on the steps, tying her hair into a ponytail.

“When?”

“No idea. I guess I’ll ask Mom when she gets back.”

“You know far well Mom won’t be back for another week,” I said. “You’re not going to brush this off and make her pay for the stupid bullshit you did!”

“Stop yelling at me! I don’t have any money right now!” Kirsty shouted at me with real frustration in her voice.

“If you don’t have any money, why would you be so careless with my car, which I let you borrow?”

“It was an accident! That’s why they call it an accident!” She stood up and got in my face. I noticed her breasts shifting around in her shirt.

“Ok, listen, I know a guy he’ll f-“

“Oh really? Is it the guy you were fucking last night?” I said, cutting her off.

“What the fu- No! Firstly that was none of your goddamn business.” She said.

“You made it my business stupid; the walls aren’t thick.”

“Jeez, you’re annoying and don’t even live here!”

“Do you think I want to be here longer than I should be? As soon as my house is sorted out after that flood, I will be gone,” I said as I checked her up and down.

“Also, even if you do know a guy,” I said, mocking her voice. “How are you going to pay him? Give him a blowjob, or let him fuck you?”

Kirsty stood there for a second until walking to the couch.

“Um, hello? I’m not done with you.” I said.

“Fuck you; if you’re not going to listen to me, I’m not going to listen to you.” She said while looking for the remote.

All I could do was let out a frustrated sigh, and I went upstairs to the spare room where I was staying. I plopped on the couch and opened my phone to text his girlfriend.

I texted my girl, ‘Hey there, babe, so darling, what do you think about coming over tonight?’

My girlfriend Sofia replied, ‘Hey baby, I so wish I could love. I’m sorry, I can’t. I have a lot of University coursework to get through.’

“Great,” all I could do was sigh, but a small part of me was happy that my girlfriend couldn’t make it. At this point, I wasn’t hard for her. Now here is the sick part, I was hard for my stupid, non-driving, shithead little sister. Fuck it, I decided to take off my pants, shirt, and even my shoes. Walking downstairs with an even harder erection in my boxers and one goal on my mind. I was so determined to make her make up for the damage one way or another.

Kirsty was flipping through the channels until I stepped in front of the TV in just my boxers. My hard cock was right in her face, strained against my boxers.

“OMG, Andy, what the fuck, what are you doing? Why the fuck are you half naked?” She asked. I slipped out my hard cock from my boxers, the tip facing the bridge of her nose.

“Listen, If you’re going to fuck up my night, my day, and my fucking car,” I grabbed the back of her head. “Then you bet I am going to get payback; guess what? I’m going to fuck your mouth. Fucking suck it.”

“Hold on, wait woah woah, what th-” Kirsty’s plea was shortly cut off by my cock entering her mouth. She immediately ran her tongue under my thick head, tasting a bit of my salty pre-cum. I then slid my cock in and out and deeper into my sister’s wet mouth and slowly thrust back and forth even more; thin drops of saliva leaked down her chin as a small smile formed around the corners of her lips. I brushed the back of Kirsty’s head while looking into her deep brown eyes.

Kirsty took her hand and caressed my heavy balls, forcing a moan out of me. She slipped her other hand into her leggings and slowly played with her wet pussy while moaning around my solid throbbing cock. I began to pick up the pace until Kirsty gagged around my cock, spitting all over my pubic hair and hips. I pulled out, giving my sister a moment to breathe.

“You..” She choked before continuing, “Like fucking your sister’s throat, don’t you?” Kirsty teased.

I smirked and reached down to cup one of her perky breasts through her shirt. “Well, consider this been the first repayment.”

She slid her shirt up and over her head, revealing her pale, perky tits. She then took her leggings off and spread her legs showing off her glistening eager pussy. My cock twitched at the sight of my sister’s pretty pink welcoming slit opening up. I began stroking my cock until she grabbed my hand.

“Well, if this is how I am paying you back, then isn’t it my job to get your cock nice and wet, Andy,” She wrapped her delicate fingers around my thick shaft.

She began spitting and slowly slobbering up and down my cock, her eyes closed as I ran my fingers through her ponytail. After a while, there was so much spit gathering around Kirsty’s lips, and my cock was overflowing, making a massive mess on the floor and down Kirsty’s body. She then pulled my cock out of her mouth and smiled up at me again.

“Are you sure you just want to fuck my mouth?” She leaned back into the chair, still smiling with thick spit lines falling down her face and neck. “C’mon Andy, don’t you want some of your sister’s pussy.” She cooed.

I then instantly took off my boxers completely and climbed on top of Kirsty’s body, my wet cock a few inches above her pussy. I braced myself against the back of the couch, breathing heavily over my sister’s sweaty forehead.

I then slowly eased my cock into Kirsty’s folds letting out a low sigh. Her pussy had just the slightest resistance to tease every nerve ending I had down in my shaft. Kirsty arched her back slightly while grabbing the back of my neck.

“Ohh shit, you’re tight. Fucking hell, your pussy feels good; I thought you’d be looser with all that cock you got last night.” I grunted.

“Oh shut the fuck up… Mmm, just fuck me dickhead.” She mumbled.

“I’m watching it. Oh fuck Andy, it looks so good going in and out of me,” She said.

I then started to slam in and out, and he was now balls-deep inside my petite sister’s pussy. She felt better than any girl I have had sex with. Kirsty’s naked body shook around her, my invading cock, getting used to my girth. Her whole face was bright red. Her eyes were wide, she was loving it, what a slut.

“H-holy shit.” She moaned. The wet skin of her inner lips gripped my cock nice and tight. I pulled out and rammed my big cock right back in with no remorse, and I didn’t give a shit.

“OH FUCK MMMM!” Kirsty shouted, but that only made me slam into my bratty sister’s tight snatch harder and faster. I was about eight strokes in until she put her hand on my stomach to get me to slow down.

“I’m sorry, Andy.” She meant that one. I kissed my sister on her sweaty forehead and caressed her face, my thumb running over her freckles.

“Oh, I guess you want me to-” Kirsty kissed me on the lips, cutting him off.

“No. Are you fucking serious? Do I fuck want you to stop. Fuck no. Keep going, fuck the shit out of me.” She squeezed her tits together as I pumped and pounded her faster. She kissed me one more time before sinking her body deeper into the couch.

“It’s going get nasty, so if I was you, Kirsty, hold on fucking tight.” I groaned deeply as I was ready to give her it hard.

“Make it nasty, make me pay for it, big brother.” She said, rubbing her hands over her tits.

I took a deep breath, and then I went back to full-on pounding my cock hard as I jackhammered my sister’s tight pussy, my body crashing into her tight body. Sweat began to fly all over our bodies and the squeaking couch. I was hitting her with deep, powerful thrusts. Kirsty’s loud moans filled my ears while her fingers worked her clit.

“Oh fuck me, fuck me, fuck me…” She chanted over and over.

“Mmmh OH FUCK IM CUMMING!” Kirsty shrieked, her whole body shook for a few seconds, and then she went utterly numb with ecstasy.

My cock wedged deep in her gushing pussy was the only thing she could think about. My mouth watered at the sight of his sister’s body writhing and squirming. My cock slipped in and out of her raw, soaking gash. Every ridge and vein of my cock was squeezed by my sister’s pussy.

I knew I was about to explode, and as much as I wanted to, I wasn’t going to bust raw inside my sister, so I decided to pull out with a wet sound. Kirsty saw my wet cock waving around, so she leaned forward, sticking her tongue out lewdly. I only needed two do a few strokes to cum all over my bratty sister’s face.

Seven thick shots landed on her. The shots lined her forehead and dripped down her nose and chin. She licked her lips, enjoying the taste of my cum.

She sucked at the rest of the cum leaking from the head of my cock. Slowly kissing the softening cock that just split her pussy, tasting her juices.

“Christ,” I panted as I mumbled, rubbing the top of my sister’s head. “You’re one hot bitch, fucking hell, that has to be the best pussy I have ever fucked.”

“Aww, what a nice brother throwing out compliments!” Kirsty said as she panted for breath.

All of a sudden, the bright lights of a car shone through the house. Kirsty jumped.

“Shit, it’s Dad!” We grabbed our clothes and ran straight up the stairs to the hallway. The front door opened, and our dad was immediately hit with a smell he couldn’t believe.

“Guys, why does it smell like a bloody locker room?” He asked. Kirsty wiped the cum off her face with the back of her leggings and put some clean clothes on. She walked gingerly down the steps.

“Hey, Dad.” She said, smiling awkwardly.

“Hey… where’s your brother? His car is-“

“Yeah, yeah, I did that. Don’t worry; we got it all figured out,” she said. She couldn’t tell if her Dad was angry, confused, amused, disgusted, or all of the above.

She went back upstairs to avoid any more questions, sharing a smirk with her big brother. “Oh, Kirsty, that was the first repayment, okay?” I said as she looked at me in a way my girlfriend would look at me.
