Horny Sister

Mindmaster on Incest Stories

“We’re going away for the weekend.” My father announced.

“And we might even stay longer.” My mother added proudly.

“No parties, Stephen.”

“Parties? The thought hadn’t occurred to me.” I lied, smiling sweetly.

“That goes for you two, Jessica.”

“Of course daddy.” She smiled as well, and she shot knowing glances at one another - mum and dead were so easy to lie to.

“See you Monday!” she waved, not offering my dad a hand as they climbed into a taxi. Me and my sister stood at the window, wooden smiles slapped across our faces, waving with increasing enthusiasm as the taxi sped away.

“Thank fuck for that.” I laughed, flopping back onto the sofa.

“Where’s the phone?” Jessica said, without a trace of irony. She threw the sofa cushions aside and found our telephone. Her fingers blurred as she dialled a number.

“Hello? Yeah, it’s me. Yep. Well, guess what; they’ve gone away! Damn right. Party at my house, tonight, spread it.” she hit the end call button and tossed the phone into my lap.

“That’s my people - call your people.” she smiled.

 

That evening our house was packed.

My sister’s friends were mainly cheerleader types, though you always get those hangers-on that look like something shat them out. My friends were of a wider variety - football players, geeks, artistic types, even a few of those ‘hard core gangster’ types.

The party was wild. Everybody had brought a bottle, or a six pack - even the people who weren’t drinking - so there was plenty to go around.

Our stereo was blasting before I could even say ‘noise pollution’. The walls creaked, as if they were going to give way, when the real bass tunes kicked in, but of course they didn’t.

At about midnight, or just after, I started dancing with this girl. I can’t remember her name, only that she was shorter than me, with a large chest, and she kept bouncing it around as she moved her feet.

As time drew on we got closer and closer in our dancing, till we were almost grinding against one another. She started reaching round to my arse and pounding my hips against hers, which must have been doing it for her since she started biting her lip and rubbing her knees together.

I manoeuvred her toward my sofa, then shoved her onto it. She fell in nicely between two other couples who were making out, and I squeezed in beside her.

I realised the guy to my left was frank, a friend of mine, and we exchanged winks as our women straddled us. Mine clamped her legs either side of me and started grinding against my crotch. My jeans started to burn as my boner slammed hard against it, the head leaping as her denim skirt rushed across its surface. She bent down over me, her lips hovering above mine.

Then, in possibly the biggest anti climax of my life, her eyes dropped and she slid off the sofa. Her curvy frame hit the floor with a thud.

I bent down to see if she was ok, but she was out cold. When I smelt her breath and felt her pulse, I soon realised all the drink had just sent her to sleep.

I leaned back and, resting my head against the sofa back, looked out past Frank.

There, standing chest to chest with a friend from my science class, was my sister. Her long brown hair was tied up, leaving her shoulder less dress to expose her neck. She was holding him tightly, and I noticed his hand slide down to her ass.

He grasped it greedily, the tight and firm flesh balling in his grip as he ran the other hand down her flawless back.

I shook my head, the drink was making me look at my sister improperly. Blinking I seemed to regain a hold on myself. I leaned in to speak confidentially in Frank’s ear.

“See that guy with my sister?”

Frank broke from kissing his girl to look over.

“Yeah.”

“Tell me if you see them go to the bedroom together, ok?”

“Sure, why?”

“I don’t want anybody fucking my sister, that’s why.”

“Fair enough.”

With that, he leapt eagerly back into the kissing.

I sighed, irritated at the idea that some guy was going to try and fuck my sister in my own house, and slumped deep into the folds of the sofa.

I must have fallen asleep then, because the next thing I remember is waking up and seeing Frank getting a blowjob off the girl he had been kissing earlier.

I smiled, impressed, and looked over to my sister.

She was gone.

“Frank!”

“Uh?” he groaned, looking up at the ceiling and squirming as the girl’s head plunged down onto his cock.

“Frank, where the fuck is my sister?!”

Frank’s head leapt off the sofa and he looked in her direction.

“Shit dude, I’m sorry.”

“You fucking idiot!” I hit him, hard, on the arm, and he squealed, but it didn’t stop him groaning.

I leapt to my feet and shoved my way through the crowded room, bursting out into the hall way.

Ahead of me was the door to my sister’s bedroom. I took a moment to breathe, then kicked it open.

 

When I burst in I had my fists up, ready to beat the shit out of the guy fucking my sister. However, when I got inside, I saw the bed was empty.

Confused, I went back out into the hall and tried my room. Again, it was empty.

It was only as I was walking toward the bathroom that I realised my parent’s bedroom door was slightly ajar.

I looked in and, sure enough, my sister was in there. Her legs were flailing up in the air as the guy, laying on top of her, thrust his hips with primal grunts.

I burst in, leaping onto the bed and grabbing the guy by the shoulder. I pulled him up, throwing him across the room. His naked body slammed against the wall and slid down.

When he rolled to his feet I was already on him, hitting him twice in the face then kicking him in the ribs. He rolled over, mumbling something about a snapped bone.

I dragged him out the door and threw his clothes after him.

“Now Jessica, I…”

I turned, ready to tell my sister she was a slut, when I saw her looking up at me with furious eyes. She was still laying in the same position, legs spread out, chest heaving, but now her brow was furrowed.

“What the fuck do you think you’re doing?!” she demanded.

My eyes trailed from her jerking breasts to her rock hard stomach, then down still to where her delicate hips framed her pussy.

“What the fuck are you looking at?!” she shrieked, suddenly pulling the duvet over herself. “Get the fuck out!”

“Jessica, I…” I steeled myself, remembering I was angry. “Jessica, don’t ever -”

“Get out!” she screamed, throwing one of my dad’s picture frames at me. I ducked out of the room, slamming the door behind me.

As I walked back toward the lounge I noticed the guy leaving. He pulled his pants up, stepped into his shoes, and ran out of the door.

I fumbled my way back into the sitting room and flopped back beside Frank. Turning my head I must have drifted off once more.

When I woke up daylight was streaming through the window and I had to squint.

I looked around, the room was empty. Not only was it empty, but it was tidy!

“Morning Stephen.”

My head whirred round, over my left shoulder my sister was standing in our open plan kitchen. She was wearing a summer top, her hair down again, and she was looking in the fridge.

“Who…Wha…”

“I tidied up.” She said from behind the open fridge door.

“Thanks.” I said, rather shocked. “You er, you’re not mad about last night, right?”

“Nah.” My sister closed the fridge door and, with a can of coke in one hand, smiled. “I understand really, you wanted to protect your little sister. I just wish you’d been a bit more…I don’t know…I wish you’d had better timing that’s all.”

“I know, I’m sorry.”

“Besides, I’m fifteen now.”

“Fifteen is underage.” I said with hypocritical disapproval.

“Fair point.” She grumbled, walking over to sit down in a single sofa chair opposite me. As she plonked down she tried to open the can, and it foamed out all over her.

“Shit!” he gasped, leaping back but failing to avoid the spray. It ran across her top and jeans in a sticky spray. “I hate fizzy stains!” she yelped, tearing her shirt up over her head. As she did so, tossing it aside, she revealed her black lace bra. Her tits swayed with the violence of the movement as she doubled over and ripped the flies of her jeans down.

Without even noticing my amazement she collapsed onto the floor and, kicking, dragged her jeans off, leaving her in her underwear.

She struggled upright, dusting her hands. The movement just made her tits bounce around that bit more.

She looked over and noticed my eyes.

“Ha, you like?” she joked, pushing them together with her arms.

“Don’t be disgusting.” I chided, eyes still locked on those swaying breasts.

“Oh really?” She asked in mock sarcasm, leaning back and putting her hands on her hips.

“Just like you were being disgusting last night?”

“Huh?”

“When you saw me naked.” she said. “You spent an awful long time looking.”

“I was just shocked.”

She smiled. Then, turning, she walked back toward the fridge. Her hips swung from side to side, tightening her arse as she walked toward the kitchen.

She pulled the door open and, taking another can out, closed it with a slam. Then she walked right toward me, big tits bouncing, and stood in front of me.

She wiggled her hips, and I realised my eyes were almost inline with her panties.

“Being disgusting?” She asked, leaning forward. As she did so she gave me a good view of her cleavage. “Come on, don’t be disgusting!” she joked, running her tongue across her top lip.

As my mouth fell open in shock she opened the can. Once again, it burst, foam shooting from the broken tin. This time, however, she aimed it at me.

The coke saturated through my t-shirt and jeans. Instinctively I pulled my shirt off and stood up, but my hands stopped at my jeans.

We were standing a few inches away from each other. Her eyes were locked with mine, and she was smiling sweetly.

“Let me help.” she teased, falling to her knees. Then, reaching one hand out, she pressed her palm against my crotch and unbuttoned my jeans.

They fell, sliding down to my ankles, and as they did so they pulled my boxers down with them.

My cock, hard as iron by this point, sprang out in front of her. The head hovered inches away from her face which, having worn a manipulative smile, was suddenly in a state of open mouthed shock.

Her eyes were locked hungrily on my member. She closed her mouth, teeth grinding against her bottom lip as she hesitantly reached a hand out to touch it.

Her hand felt cool on my cock, which sprang at her slightest brush.

Then, suddenly overcome, she stood up and covered her face.

“What am I doing?” she gasped, turning and running out of the room.

“Jessica!” I called, running after her into the hall. It was a struggle, I had to leap like a pogo with my jeans around my ankles.

“I was just joking!” she said, turning to glare at me. “You’re fucking perverted!”

With that, she ran into the bathroom and slammed the door behind her.

I rubbed my face, only now becoming fully awake, and realised what we had just been on the verge of doing. I stepped out of my jeans, pulling the socks off too, so I was totally naked. Then, bending over, I picked up my boxers and went to put them on.

As I was about to I heard a crash form inside the bathroom. My immediate fear was that Jessica had slipped and banged her head on the tiles.

I ran to the door and called through it.

“Jessica?”

“I’m fine!” she screamed back. “Leave me alone!”

I heard the rush of the shower start up. I slumped tiredly to the floor, boxers still in hand, dick now flopping limply across my thigh.

I dozed for a while, nodding off for a few minuets, when a sudden gasp brought me completely round again.

It was my sister’s voice, but it was a short and sharp gasp, like of a sudden pain.

I went to call out, when I heard a long moan. I realised then, hearing as the moans rumbled under the noise of the shower, that my sister was fucking herself.

I shuffled over just a bit, and pressed my ear to the door. As I did I could hear her gasping to herself, and the slap of her arse against the tiled wall.

At this new proximity I could hear her whispering to herself between gasps.

“Please cum.” she was urging, almost silently, between moans. “want to fuck…Stephen…please cum.”

She was thinking about me, apparently, but she wanted to cum? I guessed she must have been trying to stop herself thinking of me by making herself climax, perhaps she thought that would soften the desire.

I pulled myself onto all floors, ears pressed against the door, as she began to finger herself more furiously.

Her moans became louder, daring even to sound over the rushing water as I heard her slam her own arse against the tiles, apparently fucking herself so hard it shoved her hips back. “fuck me…” she was whispering, obviously struggling to keep her voice down. “fuck me Stephen…make me cum…”

My cock was hard again. It was so hard I could feel it up against my stomach as I pulled myself upright. Then, wrapping a hand around it, I started to beat off to my sister’s wild groans.

“fuck me…please…Stephen…”

That time she really had gone louder than the shower. She must have been losing control, desperately trying to make herself climax. I could hear her begging for the imaginary me to finish her off.

“please… your cock…fuck me…”

It was too much for me. I kicked the door, hard.

It flew open - she hadn’t even locked it.

I looked over to her in the shower. The curtain was pulled away, water cascading down her huge tits and flat stomach to where her hand was still furiously fingering her clit.

She leapt back, gasping, but her hand did not move from her pussy.

I jumped into the shower and, pressing myself against her, bit her neck. As I did so my throbbing boner pressed hard against her hand.

Her eyes widened as her hand hesitantly left her pussy and, gently, rapped around my cock once more.

“Is that?…” she ran one slow stroke down its length, jaw dropping slightly when she felt it all the way to the base. “That’s so…big.”

I stepped forward once more, the huge warm member between my legs pressing flat against her pussy lips. She bent it slightly, teasing her lips with its huge swollen head.

I leaned forward, lips against her hear, and whispered under the water. “I’m going to make you cum.”

Without a moment’s hesitation she grabbed it and guided it into her pussy.

That first thrust was heaven. My burning member squeezed into her tight passage, reaching far deeper than her fingers ever could. She let out a long, guttural groan, as if a tremendous temptation had just been fulfilled.

She opened her eyes and, locking gazes with me, she pressed her tits to my chest.

“Fuck me.” she hushed, arms rapping around my hips. “Fuck me till I break.”

She shuddered underneath me, the water running down my back as I slammed my cock home.

Her arse bounced off the tiles so hard she propelled against me and drove my cock home for a second time. Her tits were pressed against my chest, and I was gnawing at her neck when I slid home a third time.

“Oh Jesus.” she gasped, leaning back against the tiles. “You’re so fucking big.”

“Fuck me!” she gasped, her hips ramming against mine, her pussy greedily eating up my cock. “Fuck me Stephen, now!”

She leapt onto me, legs wrapping around my waist and arms tying around my arms as she rocked her hips against my cock. “Yes!” she wailed with delight.

I fell, landing on my back with her on top of me. The shower water still powered onto her hair and down her neck as she began to ride me.

“I want you to fuck your sister.” She said dirtily, once again making eye contact from between her huge breasts. “I want you to slam your cock into me till I scream with delight.” She began riding my a bit faster, rocking back and forth with my cock buried deep in her pussy.

“Yes…” she gasped, closing her eyes and turning her face upwards. “I need to cum.” she said quietly, planting two hands on my chest. “Don’t move, that’s it. Please, I need to cum soon.”

“Do you want me to fuck you?” I asked, sliding my cock deep into her again.

“Yes!”

“You want your brother to fuck you?”

“Yes, brother, fuck your sister!” she began jerking, her tits swaying wildly and knocking against themselves as she slammed down on my cock.

“FUCK ME!” she pleaded, bucking like a wild animal as my cock throbbed inside her. “PLEASE! I need to cum!” she gasped, eyes wild as her wet hair streamed across her face. “fuck me with your huge cock!”

That was enough for me. My nuts tightened suddenly, and I felt my cock swell once against and burst deep within her. I thrust upwards, slamming my cock home so hard she shuddered.

“YES!”

Her pussy tightened like a vice, lips clamped around my cock as she began ripping herself up and down my shaft. Her huge tits jarred as she slammed my cock home and came to a screaming orgasm, bouncing like an animal.

“Yes!” she exhaled, rolling off me. My cock sprang out of her pussy with a little jolt, completely clean of cum, and she flopped onto the floor beside me.

“You did it.” she said between gasps, her tits heaving and sinking.

“I can do it again, if you want.”

We looked at one another, and she smiled.

“We have a whole weekend.” she said, baring her teeth as she went to climb onto me again.
