Eeping up with the Joneses

It was the first day of summer and the day after my eighteenth birthday. I was at home playing some computer games when my phone buzzed with a text message from my sister Isabel. "Hey bro. I have a favour to ask. My laptop is going really slow. Can you take a look at it?" The request was straightforward, but little did I know how deep the rabbit hole that message would take me down was.

My name is Alex Jones. I just turned eighteen and will be starting my senior year in the fall. I'm a bit of a nerd - I like computers and video games, but I also do long distance running. None of that 'fat lonely geek' bullshit stereotype here. Well, except maybe the lonely part - I've never really had a girlfriend. I don't let that get me down though; I've got some good friends and an amazing family.

My dad, Lewis, works for the government's foreign service - he's away a lot - and my mom, Pamela, is a librarian. I have three sisters. The eldest is Fianna; she's at college studying to be a doctor. Next in line is Catherine. She goes to an acting school in the city. I love my big sisters, but the sister I've always been closest to is Isabel. She's only a year older than me. I'll really miss her when she goes off to university this autumn, but for now, I've got the whole summer stretching ahead of me.

Mom's chinese, so my siblings and I all have black hair and brown eyes, but dad's from the UK and is 6'2". As a result, we're all a pretty tall bunch - I'm 6'4" and my sisters are all almost 6' tall as well. To be honest, I've always found my mom and my sisters extremely beautiful, but, well, more on that later. You'll see.

I went into Isabel's room and sat down at her desk to check out her laptop. Sure enough, it took forever to boot up. I stood up and stared out the window in front of me while I waited for the operating system to load. Mom was outside on the patio, wearing a dark blue bikini. Whenever we visited them, her sisters would always laugh at how dark my mom's skin was. Like a lot of chinese women, they tried to keep their skin as white as possible. Mom didn't care, though. She liked the sun and didn't mind the tan she got. I didn't mind either. I thought she looked stunning. She kept in good shape, she didn't let being in her early forties slow her down, and her stomach was toned and flat despite having had four kids. As I watched from the window, she walked over to the edge of the pool, her ample breasts bouncing slightly under her bikini top. I knew it was wrong, but I felt my cock throb in my boxers as blood pumped into it. When she bent over to test the water with her hand I couldn't help but stare as her plump, round ass raised towards me. I reached down to shift my engorged cock to a more comfortable position in my boxers and sighed as I watched her execute an elegant dive into the water.

A chime from the desk beside me brought me out of my reverie as Isabel's computer let me know it was finally finished it's laborious boot up and I sat down again to begin trying to figure out what was going on. After some sleuthing, I discovered she had a ridiculous number of useless and somewhat harmful background processes running and I started shutting them down and trying to uninstall them. It wasn't very exciting stuff, but what I found when I opened her browser to install some anti malware software was the exact opposite.

Her download folder was full of porn. Not just the vanilla stuff, either, although there was plenty of that. It was pretty much an a to z of debauched sex. I picked one at random and opened it up to see three guys stuffing a stacked blonde full of cock-meat. Below the desk, my dick sprang to attention once more and I unzipped my jeans to give it some air. Half an hour later I was still clicking through her library of depravity and my engorged organ was pulsing uncomfortably. Finding out my sister was such a porn-hound was pretty surprising, but the next video I opened doubled my astonishment. It was of Izzy. She was naked on her bed, legs spread, a huge dildo half in her cunt. My penis tensed urgently.

"Oh, jesus, Alex, I didn't think you'd find that!"

My stomach did a somersault as it tried and failed to climb out my mouth. It was Isabel's voice. I hadn't heard her get home, and here I was sitting in her room, nursing a massive erection while watching a video of her masturbating with a horse sized dildo.

"Um, yeah, sorry, I was just fixing your computer and I stumbled on it," I stammered, trying to surreptitiously stuff my cock back into my jeans. The damn thing was too hard, though, and I was still in the process by the time Isabel had rushed over to the desk to slam her laptop closed.

Her eyes went wide as she looked down to see my rampant hard-on. "Holy shit, bro!" she exclaimed. "That thing looks painful."

I blushed furiously and stood up to try and make it easier to put my cock back in my pants. "Sorry! I couldn't help it!"

"Hey now, not so fast," she said. "You've seen my embarrassing shit. Only fair I get a look at yours." She swatted my hands away from my crotch and smirked as she stared at my bobbing phallus.

Isabel was skinnier than my mom and my other two sisters, but my mom's genes left her with an impressive set of tits and the spaghetti strap tank top she was wearing displayed those assets well. She was wearing a tiny pair of jean shorts and had her shoulder length black hair up in a pony tail. She looked amazing, as usual. I felt a heavy bead of pre-cum ooze from the tip of my dick as she inspected it.

"Why isn't it going away?" she asked.

"I don't know," I said, embarrassed. "It's not like I have total control over it. Can I go now?"

"Not yet," she grinned evilly. "Make it go down and then we're even."

"What the fuck, Izzy," I whined, "do you know what you're asking?"

"Hey, fair's fair. You saw me masturbating. Finish what you started." She reached beside her to grab a box of tissues from the desk and threw them at me. As I fumbled to catch the box, I stumbled backwards and ended up sitting down heavily on her bed. "Go on," she insisted.

My cheeks burned as I tentatively wrapped my fingers around my aching cock. Isabel was standing before me, hands on her hips, biting back a laugh as she watched me slowly pump my hand up and down my shaft. Another thick bead of pre-cum squeezed out of the tip.

I was a young man. I'd obviously masturbated numerous times before. Sometimes I'd even closed my eyes and imagined one of my hot sisters touching my cock while I did it, but something about Izzy standing in front of me, in the flesh, made the task exceedingly difficult. I don't know how long it had been, but it felt like I'd been stroking my cock for hours and yet, despite my burning need, nothing was happening.

Izzy plonked herself down on the bed beside me. "What's taking so long?" she asked.

"It's hard with you watching."

She raised an eyebrow, eyes still locked on my raging manhood. "It certainly is."

"Hey, don't joke-" I began, but my words were cut off when I felt her grip my wrist and lift my hand to her chest, pushing my fingers against where her left tit strained against the thin cloth of her top. I squeezed my hand reflexively, fingers sinking into the soft flesh of her breast, and felt her hard nipple poke at my palm. "Oh god," I moaned.

"You like groping your sister's titty, you dirty boy?" she asked, leeringly. "You like squeezing your sister's tits while you stroke your cock?"

Her words were so dirty, so lewd, I'm pretty sure I lost at least a little bit of my sanity right there. It's the only way to explain the strange disembodied sensation that kept me in that room, jerking off in front of my sister while groping her boobs. My hand was sticky with the copious pre-cum that was oozing from the tip of my dick. I pumped furiously with one hand while I mauled her pert breasts with the other. My debauchery was interrupted briefly when she moved my hand off her chest and I watched hungrily as Izzy peeled her top up over her head, leaving her bare chested on the bed beside me. I instinctively reached up with both hands to grab her ripe tits and pinch her small, erect nipples. Now it was her turn to moan.

"Oh fuck," she sighed, "that feels nice." Sliding her arm under mine as I manhandled her breasts, Izzy wrapped her long, slender fingers around my throbbing shaft. Her fingers felt cool against my arousal flushed skin and I couldn't help but gasp as she tightened her grip and pumped her hand up and down a few times. "You've got a pretty big cock, bro."

I blame my missing sanity for what I said next.

"Can you..." I swallowed anxiously. "Can you suck it for me?"

"Okay, but I want you to eat me out while I do it."

I couldn't believe what I was hearing. My mind may have decided to take a vacation right then and there, but my body seemed to know what it was doing. I scooted backwards until I was lying on my back on her bed, undid the button on my jeans and began to shimmy out of them, all the while watching Izzy as she stood and pulled her shorts down to reveal her mons. She had shaved her pubic hair to a small strip. Below it, in the cleft where her thighs met her pelvis, I could see the contours of her cunt and delicate labia. They glinted wetly.

Once we were both nude, she climbed onto the bed, crawling on all fours and turning to swing a leg over my head. A moment later I was staring up at her quim, stunned by what was about to happen. I could feel her hot breath caress my pulsing glans and groaned loudly when I felt her wet lips touch and then slowly engulf the head of my cock. Remembering our deal, I reached upwards to hook my arms over her thighs, sinking my fingers into the firm flesh of her ass cheeks, and brought her cunt down to my mouth. Her pussy smelled musky and a bit sweaty. The aroma was intoxicating. I stuck out my tongue and licked it from her mons to her perineum. Isabel moaned in approval, my cock still stuffed in her mouth, the utterance sending delicious shivers through my tumescent organ.

With a wet slurp she began bobbing her head up and down, sucking my cock with an eagerness that was incredibly sexy. I tried to reciprocate as best I could and pushed my face against her crotch, trying to push my tongue as far into her depths as I could. I'd never gotten this far with a girl before, so I was inexperienced, but her cunt had an arousingly sweet and sour flavour that was irresistible, and I alternated between hungrily lapping my tongue against it and kissing and sucking on her clit. Isabel was clearly not inexperienced when it came to blowjobs and her oral ministrations felt divine, but I must have been doing something right - she moaned around my girthy tool and pressed her naked body against mine so as to grind her pussy against my face. I could feel her spit trickling down my shaft and oozing over my balls. The wet, warm confines of her mouth and the soft touch of her tongue against the sensitive skin of my glans was exquisite. I didn't want it to end, but even as I gamely tried to hold back my coming orgasm, I could feel my balls tighten with need.

"'M gonna cum," I said, my words smothered by the cunt smashed against my lips.

"Hol' on," she said, her words muffled by the cock in her mouth, "almoth there!"

I sucked hard on her clit, drawing it into my mouth and rubbing my tongue against it, and was rewarded for my efforts by Izzy pushing her hips downward, hard. I felt her ass tense under my grip and there was a sudden gush of sweet-sour fluid into my mouth. She moaned loudly and her body shuddered in my grasp before she suddenly took my whole cock into her mouth and slurped vigorously. It was like she was trying to suck the cum out of me and straight down her throat. I couldn't fight it. My jism spurted volcanically into her throat and my cock throbbed with relief. I had never felt an orgasm like that before - my balls twitched and heaved and a huge torrent of sloppy cum seemed to squirt endlessly into her warm mouth. I must have unloaded a litre of semen into her, but Izzy never stopped sucking. She gulped and swallowed each jet of cum until my cock ceased it's frantic pulsing and began to grow soft.

I flopped back onto the bed, completely drained, and Isabel rolled sideways off me. The realisation of what had just taken place dawned on me. "Fuck, Izzy, what did we just do? You're my sister!"

"Oh, quit overreacting," she replied. "It was just some fun."

"Just some fun?!"

"Well, it was, wasn't it?" she shrugged, "What's the harm? We're two consenting adults, aren't we? Anyway, you were pretty good down there." She nonchalantly reached between her legs to massage her cunt slowly and then looked down the length of her naked body at me. Grinning impishly, she said, "Besides, a big sister's gotta take care of her little brother, right?"

I couldn't help but grin back. "I guess," I said. "Can we do it again?"

She laughed. "Get out of here, you randy fucker. I said I'd help mom with dinner."

*****

The next day was rough. I was supposed to be helping our neighbour Peter build a new back deck, but I couldn't stop thinking about Izzy's warm, wet mouth sucking on my cock. I wanted to have her again, I wanted to taste her sweet cunt. Lewd thoughts of fucking my sister had made the day drag out interminably and I'd ended up scattering a box of deck screws all over the grass and screwing up a few cuts with the circular saw.

When Peter finally called it a day, I immediately fired a text over to Izzy. Her response was disheartening. "Sorry bro. I'm heading over to Anne's place tonight. I think the Braggs are coming over for dinner with mom and dad tonight so they told me to stay the night over there."

I sighed regretfully and was still feeling a little glum by the time I got in the front door. Through our open-concept living room I could see the kitchen, where dad was taking a bag of marinated burgers out of the fridge. He waved at me. "Hey kiddo."

"Hey dad. Izzy told me you're having the Braggs over for dinner?"

"Yep. Gonna barbecue up some burgers. First barbecue of the summer, eh?" he replied cheerfully as I took off my shoes and walked over to grab a can of pop from the fridge. "Say, if you want to stay over at Joshi's house or something tonight, I'd let you take my car. I'll throw in some cash for a movie and some pizza. It'd be good to have you kids out of the house."

"Yeah, sure. I'll give him a call and see if I can hang out."

Joshi Krishnamurti was my best friend and fellow nerd. We were both on the track team and hung out all the time. His parents were usually pretty happy to have me sleep over and it was no surprise when he said it was fine if I came over, especially when I mentioned I had the car and we could go out for a movie.

We caught the latest superhero flick and stuffed ourselves with pizza, but when I asked if I could stay over, he mentioned he and his folks were heading out early to visit family the next day, so I ended up driving home late that evening. The Bragg's car was still next to mom's van by the time I got home, so I parked behind our van to leave them enough space to get out. I could hear Miles Davis' music drifting from the backyard and could see the patio lights as I walked through the front door and over to the kitchen to grab a glass of water to take upstairs to my room. I figured I'd leave them to it and go play some some computer games or something. It's not that I didn't like the Braggs. Quite the opposite, actually. Hank Bragg was a work colleague of my dad's; a huge, muscled black guy who was always friendly and down to play some video games whenever he was visiting. His wife, Mia, was just as friendly, but I was always a little awkward around her, mainly because of how incredibly hot she was. Tall, stacked and in incredibly good shape, with long, wavy hair and kind eyes, I always found myself blushing nervously whenever she spoke with me. Hoping to get a glimpse of the beautiful woman, I took a peek out the window.

The patio lights cast an orange glow over the back deck and the remains of dinner. Two empty bottles of wine sat in the centre of the dinner table. Clothes lay draped on the backs of the chairs around it. Mystified, I cast my gaze towards the pool, where I saw dad lying on his back on one of the long pool chairs. He was completely naked. Mom was on top of him, tits mashed against his chest, her lips locked to his in a passionate kiss. They were fucking vigorously. My mouth went dry as I took in the scene, but what was primarily responsible for my sudden cottonmouth was the sight of Hank standing behind my mom, driving his immense black cock into her asshole with buttslapping relish. I fumbled and almost dropped my glass of water and my cock made a concerted attempt to tear its way out of my shorts.

As I watched, mom broke off her kiss with dad and propped herself up, her hands on dad's chest, and arched her back to stick her ass out for Hank. The big man reached his arms around her to cup a breast in each hand, his hips pumping steadily all the while, as he and dad double penetrated my mom. I could hear the meaty smack of his thighs against her ass and her moans of satisfaction.

I couldn't help myself. I put down my glass of water and reached down to free my stiff cock from my shorts and began to masturbate as I watched my mom get serviced by my dad and his friend. The scene was electrifying and my fist squeezed pulses of pre-cum from my swollen member. Just as I thought it couldn't get any better, however, I saw Mia climb out of the pool. She was just as naked as the rest of them and the water glittered in the light as it cascaded off the curves of her body. Her huge breasts glistened wetly. They were round and brown and, although they were a fair bit larger than my mom's, sat high on her chest, probably because she hadn't had any children. She knelt behind her husband, who's cock was balls deep in my mom's ass, spread his buttcheeks and began to tongue his ass. Soon he and my dad's lusty grunts joined with mom's moans to mingle with the jazz coming from the backyard speakers. I could tell the two men were both about to pump their seed into my mom's stuffed holes and the debauchery of it all made the cum start boiling up the length of my cock. I hurriedly looked around and grabbed a paper towel with my free hand. As I looked up again, I saw both the guys stiffen. Hank's hips made small bucking motions as he began depositing his semen deep inside mom's bowels. My own cock chose that moment to start pumping cum into the paper towel. The orgasm was intense and bit my lip hard. As I rode out the waves of pleasure I watched mom look over her shoulder at Hank as he filled her ass with jizz. As her head turned, her gaze passed over the back of the house and the kitchen window I was spying from. She must have seen me - the kitchen light silhouetted me perfectly. For a moment, her eyes seemed to lock with mine, my cock spewing cum at the same time her ass and pussy were being pumped full of the stuff. I don't know how long the moment lasted - probably just seconds - but as soon as I regained control of my legs, I turned and bolted upstairs to my room, cheeks burning.

A couple of hours later I heard the burble of conversation followed by the sound of car doors closing and figured the Braggs were leaving. "Alex must be home. The car's in the drive," said my dad, voice muffled by my closed door and the floor between us. "I, um, wonder what time he got in."
