Hey all,



Flameboy580 aka Emmett Vosh here,



I went in and edited some of the errors and added a few new lines.



Thanks for all the love and support!

************************************************************************************

My life was a little complicated, but it wasn't so bad.

Actually, I should probably tell you who the hell I am first huh? My bad.

I'm Jennifer, but most of my family and friends call me Jen. I have an older brother, Tyler, which we usually shorten to Ty. My family is big on monosyllabic nicknames, if you hadn't noticed yet. Even my mom's name is Mel (Melanie). My dad's name is Frank, which can't be shortened easily, so we tease him about it instead. They both work long hours, so we don't get to see them much except maybe on the weekends.

I am short (5'3"), nerdy and not athletic whatsoever. My skin tone is pale and light, since the "great outdoors" doesn't usually have a decent internet connection. I'm sort of a weird, gamer girl/otaku (anime fan)/awkward duck. Most people tend to assume I'm a nerd when they see my glasses, which I wear since I'm nearsighted. I have black hair that's mostly straight, which serves as nice contrast for my rounder face.

Physically, let's just say I have a bit of extra meat on my bones. My belly has some extra chub, which I can be pretty self-conscious about. My insecurities aside, I will say that the extra bits of fat have done wonders for my curves. My tits are voluminous sure, but I am most proud of my ass and thighs though, which look pretty damn good if you ask me.

My looks don't keep me from being awkward as fuck though. I often trip over nothing and my social skills consist heavily of surprised squeaks and awkward mumbles.

I turned 19 this year. I graduated high school last year and am currently living at home. I am trying to sort through the I-don't-have-a-clue-what-I-want-to-do-next phase of my life.

Sounds pretty normal right? Just wait.

Ty is 3 years older than me (22) and has always been a jock, having ran track and played soccer in the past. I can't deny how handsome he is, standing at 6', with his delectably sun-kissed tan and nice lean muscle definition. He has dark hair like mine and lovely brown eyes that shine when he smiles.

My brother has always been sweet and caring, the kind of brother every little sister dreams of. He stepped up to take care of me while our parents worked growing up, and it made him seem so mature. My parents would freak out if they knew I was going out with a boy, whereas my brother made sure I had condoms and pepper spray on me. He would give me backrubs or cook dinner for me when I was upset and helped me study for my exams back in high school. Whenever I sought solace, my brother was the one I turned to. We have been close for as long as I can remember.

If it wasn't already obvious, I have a huge crush on my brother. He has been there for me more than anyone else in my life, and I can't deny that I've subconsciously compared all my love interests to him.

To be fair though, I didn't really think of him (or his girlfriend) sexually until recently.

***

It was a Thursday afternoon, right around mid-spring. I was hanging out with Chelsea, a friend of mine, that day. We were shopping for cute clothes, eating yummy food, hanging out having girl talk, you know, the usual. We usually hung out for most of the day, but today was different. She got a call shortly after lunch. Apparently, her dumbass little brother got in a fight in his middle school and his mom asked her to go pick him up. She said we would reschedule later and swore she would "make his dumb ass pay!"

Bummed that my hangout was cut short, I went home.

I noticed Syn's car in the driveway but didn't think anything of it. Syn, or Sydney has been dating my brother for about 2 years now, and she was always coming over. She is a year younger than Ty (21) and is about 5'6". Syn adores me and never fails to compliment me, which has increased my self-esteem bit by bit over the past year or so. We hangout a lot and always have a blast. I have nothing but admiration for her, but something about her makes me a bit nervous around her. When she heard about my family's name shortening, she insisted we call her Syn instead of Syd. Supposedly she reflexively slapped Ty the one time he called her Syd as a joke. I agree with her though, Syn suits her better.

"At least it wouldn't be boring today, it never is with her around." I thought to myself.

I had no clue how prophetic that thought was going to be.

I checked the mail. What did I find? "Jennifer, we think you are a great fit for fucking-butt-fuck university, apply now!" Yeah, because nothing draws my interest to a campus quite like junk mail. Annoyed, I went inside and headed to my room to sulk.

As I slowly opened the door, that's when I heard them. Well specifically I heard Sydney screaming and cursing. I quietly closed the door and tiptoed past the kitchen, turning down the hall and found that Ty's door was cracked open. I peeked inside...

Ty had Syn on all fours on the edge of his bed and was standing near the bed pounding into her. Both of their athletic, toned bodied were glistening with sweat. My mind reeled as I took in Syn's silky caramel skin and Ty's dick, which looked like it was stuffing her.

Sure, all couples have sex, but if you knew my brother, this was not the first thing you would picture. While my brother is a tall, strong guy, he is a bit of a gentle giant. He is more of a sweet boy than a rough boy...but you wouldn't know seeing him now. This was not sweet, candle-scented lovemaking; Ty was destroying Syn's pussy.

From the screams and expletives pouring from Syn's mouth, and the unmistakable sound of flesh smacking dripping wet flesh, it sounded like it felt fucking amazing.

I stood in the doorway, transfixed as my hand moved down my navel toward the growing heat that was spreading through my body. I found them fumbling with the button on my shorts.

Syn began groaning louder, and I heard her beg "Fuck Ty please don't stop, that feels so fucking good!"

Grunting, Ty slapped her ass hard before digging his hands into her sides and pulled her further onto his cock with each thrust.

My hand found its way to my clit as I watched. I knew that this was wrong...that I shouldn't be watching this, but I couldn't look away.

Syn screamed louder before she began trembling around Tyler's glistening cock. Her short chestnut brown hair flew back and forth across her gorgeous flushed face. Watching her shaking as the force of her orgasm rocked through her, I felt rather than heard a moan escape my lips before putting a hand to my mouth.

When she stopped shaking, I saw Syn pull my brother's dick out of her and flipped around to face Ty with a cheeky grin "Alright sex beast, It's your turn!"

Tyler smirked, leaning into her face to kiss her, "Oh yeah?" His question was a challenge and a taunt.

"Get the fuck on the bed!" she ordered before pushing him into position. My jaw slackened as I saw my brother's dick: no, it wasn't a 10-inches-of-doom porn star dick, but it was thick and bigger than anything I had ever seen. It stood straight up as he landed on his back, and I could see the slick juices coating it. Knowing that right now, Syn's pussy was that fucking wet was hot, but knowing it was my brother's fat cock did that to her brought me to the brink. I wanted to taste her juices...I wanted to taste her on his cock.

She faced away from me before climbing over his legs to straddle him. She teased the head of his cock by dragging her dripping wet pussy lips over it. "Do you want to cum in me, or do you want to cum in Jen's tight little pussy?"

I froze. It was hard to see through the crack in the door, but I swore his cock twitched when she said my name. I couldn't see Syn's face as she said it to tell if she was joking, but the little moan at my name told me she wasn't.

"Mmmm" she groaned as she took him all the way into her dripping opening, causing Ty to moan in ecstasy. "You know you want to. I want to make your sweet, baby sister cum all over us."

My hand began stoking my clit with renewed urgency now.

Tyler swore as he slapped her ass. Syn took that as encouragement to go faster.

"She'd probably be so tight, gripping your cock as you stretch her wet little walls-" she paused, unable to stop her own moans of pleasure, "I'll bet she would feel so good on your fat cock, baby."

My legs began trembling as I felt myself become drenched. My orgasm rising again within me as I stood watched them.

Syn began moaning more, her breathing became heavier as she rode faster. "Fuck your baby sister, Ty" she began moving more forcefully, grinding his cock into her g-spot with each pass. Her hips began moving so fast it caused her ass to shake in a mesmerizing rhythm.

"I...I've wanted to do this for so long Ty, please don't stop!" Her impression of me was...good, really good. They had done this shit before, and hearing it made my legs began to tremble beneath me, threatening to buckle.

I saw my brother begin to tense up as she assaulted his cock, and his breathing became heavier. Before long he groaned "Fuck! Jen...I'm...close"

I heard her scream "Fuck me baby...fill your baby sister with your cum!"

Ty grunted, grabbing Sydney's hips and impaling her deep as he came, leaving her screaming and twitching as his cum shot inside of her.

I bit my hand in a vain effort to stifle my moans. It was too much, my walls began contracting, desperately seeking to be filled as a powerful orgasm hit me. I came so hard my legs gave out. I slid down the wall, my legs unable to support me as wave after wave of pleasure rippled through me.

Syn seemed to recover first, her breathing still heavy and my brother's cock still deep inside her. Ty still had his eyes closed. She turned her head toward the door with a smirk on her face. Our eyes met for a flash before I panicked and leapt up, fumbling for my room next to his.

Somehow, I managed to not trip and fall. When I made it to my room, I closed the door, but not all the way, since my door made a loud sound when it closed. I strained my ears to see if she was following, but I couldn't hear anything over my pounding heartbeat and heavy breath.

"Calm down" I thought to myself over and over "maybe she didn't see me." When I caught my breath, I zipped up my shorts and sat on my gaming chair, opening my PC to pretend I was playing a game if they came looking for me. As moments that felt like eternity passed, I decided they probably weren't coming. I opened Steam and threw on my gaming headset in an attempt to distract myself but knew damn well I was too wound up to play anything right now.

I tried searching for porn or manga, or anything, but images of Syn getting roughly fucked continually replayed in my head. Syn's moans echoed with the sounds of my brother's grunts as he filled her. I couldn't stop myself from getting aroused again. Half confused by what I saw, and half aroused by it, I once again felt myself unbuttoning my shorts.

Did my brother's dick really feel that good? Syn was so wet she was practically dripping, and they both looked so hot covered in sweat. How often do they fuck like that? How had a I never heard them?

Heat began to spread through my body each time it the memory replayed. That wasn't the first time they role-played like that. Syn was too natural at it, her impression of me was a little too practiced...and it made Ty...my brother...cum? The thought of cumming in his little sister drove my brother over the edge?

My head spun, the influx of thoughts overwhelmed me; or maybe it was just intensity of my clit stroking, which was attempting to ease the burning desire I felt. I couldn't help the moans coming out of my mouth. I leaned back in my chair and pulled my shorts further down.

What if this was just the first round? What if I heard them going at it again? Would I watch them? The thought of watching Syn getting fucked again did things to my body you wouldn't believe. I always thought she was attractive, but she wants to "make me cum all over them?"

I slid a finger inside while the other hand worked my clit. I moaned as my fingers found my sensitive g-spot.

My brother isn't the only one who has fantasized about fucking me, but Syn has too? The thought sent shivers down my spine. Syn was fucking hot, and sure looking at Syn would make me feel aroused, but I always thought it was because I wanted to be like her...but now part of me wasn't sure. Of course, a larger, more honest part of me knew...I wanted her just like I wanted my brother.

I pictured myself laying between them, my brother's cock pounding into me while Syn straddled my face. I imagined Tyler's pace hastening as he began to grunt, and my tongue moved faster to match it on Syn's clit. I pictured my slick walls gripping his thick cock as they stretched me to my limit. I heard Ty saying he was close, that he was going to cum soon...

Then I remembered the line that was my undoing: "Fill your baby sister with your cum!"

My orgasm burst through me. I was writhing in my chair as my entire body trembled. My pussy erupted with fluids, and all thought was lost in the onslaught of the pulsing waves of pleasure that tore through me.

After several moments I came down from my orgasm...sore from the trembling, but so satisfied.

When I recovered and was pulling up my shorts, I realized my mistake. I had left the door cracked and still had my noise-canceling headset on! They could've been watching me the whole time and I wouldn't have noticed!

After readjusting my ponytail and clothes, I decided to tiptoe my short ass towards the door and check the hallway. All clear. The hallway was humid and smelled of soap. They had probably taken a shower, which I realized means they might've heard me. Dread and embarrassment enveloped me. I was so fucked, they probably knew! Would Syn tell Ty if she heard? Had Ty heard me?

What would he say?

What would he do if he had?

I stayed in my room, wallowing in my thoughts and embarrassment for a time before my body demanded hydration. I crept to the kitchen to grab some water. As I passed, I glanced over to find Tyler's door closed.

I grabbed a water bottle and began downing it when I heard a door opening, followed by footsteps coming from the hallway toward the kitchen. I attempted to steel my nerves, hoping to sound casual.

"Oh" said my brother, clearly surprised to see me. "Hey, Jen, I didn't hear you come in!"

"Here in yeah ago I..." was the mumbled product of my pitiful attempt to sound casual. Flustered, I tried to recover "I mean...uh...yeah I just got home a...a little bit ago." I knew my cheeks were reddening.

His cheeks were a bit red too as he said, "Oh, well I was just grabbing some water for Syn and I." He reached into the fridge to do so "How was hanging out with Chelsea?"

My mind stalled, unable to remember what he was talking about. After a moment I remembered that before my mind was filled with filthy images of my brother and Syn that I was hanging out with Chelsea at the mall. Ty noticed my long pause, tilting his head before he said "Jen?...you okay?"

Stumbling over my words, I managed to say "huh? Oh um, yeah, the mall was fun! You know how Chelsea is, always a bundle of energy" I finished with a nervous laugh before taking a sip of water.

"Well, that's good. You are back earlier than I expected!"

I scanned his face for signs of disappointment but found none. "Oh yeah, her brother got in a fight at schoo.l"

He laughed at that "I'll bet she was pissed! Let me get Syn her water real quick, but want to watch a movie with us or some-"

He was cut off by a cheery voice from the hallway, "Is that Jen's unmistakably cute voice I hear in there?" Syn rounded the corner with a bright smile, her pixie cut hair still wet from the shower, "I thought so!" she sang. A moment later she rushed over to hug me, a little tighter than she usually did. I couldn't help but blush as I remembered what she looked like without the white tank top and blue capris she currently wore. I also noticed she wasn't wearing a bra.

"Looking good today, Jen!" She complimented as she eyed me up and down, "but you always look good" she added with a wink.

I could only laugh nervously, mumbling something about how these were just casual clothes.

Ty cut in to hand her the water bottle, which she thanked him for before chugging it down. She held her hand out for another while she kept looking at me, a mischievous grin creeping on her face.

"We just finished a workout, so I'm parched. This bastard knows how to work me" she added, elbowing Ty in the side.

I felt my face redden slightly. Did she know? She had to have. I looked away from her, nervously laughing and replied "yeah...you guys are crazy".

She waited until I looked back at her to stop drinking, turning toward me, "You have no idea" she said with a little wink.

Her tone suggested that I should come find out exactly how crazy they are.

Ty saved me from my awkwardness, asking if I wanted to do something with them.

Desperate for a topic change, I said, "Oh I was just gonna...um....play some video games or something?"

Syn finished her second water before glancing over to the tv in the living room. "Is the Wii-U still set up? I gotta kick Ty's ass for beating me last time."

"And the time before that" Ty added with a smirk, earning himself another playful elbow.

Fire ignited in her eyes, "You are going down!"

"Sure, I'll set it up. Mario Kart?" I asked, still having difficulty looking either of them in the eye.

Syn wasn't much of a gamer, but she was always down for a competition, even if she knew she would lose. She was a quick learner though and her determination to get what she wanted was awe inspiring.

"Actually," Ty interjected "before we do that, are you hungry, Jen? Cause I'm starving!

Syn and I agreed and after some discussion we decided to have Ty cook us something instead of ordering out. Ty learned how to cook early on from my grandma and would make dinner for us on most nights. I'm a decent cook, but not as good as he is, which I have always been a little envious of. But hey, at least I'm better than Sydney in the kitchen...but then again even bad cooks don't burn everything. She is the type who turns the heat up to 8 to cook eggs because it was taking too long. If there was ever a competition to burn something the fastest, my money would be on her.

I watched Tyler cook. He wore an apron over his maroon t-shirt. An apron I knew he wore out of consideration for me, since I usually did the laundry, even if he wouldn't admit it. Ty was always putting our needs before his own.

He made mac and cheese with seared chicken breast and spinach, which was bomb!

We ate and loaded the dishwasher before heading to the couch to play.

At times, it surprised me how easy it was to fall back into my old ways with them, like nothing ever happened. But every now and then, I'd look at one of them and notice just how good they looked. I was incapable of ignoring my brother's handsome face, or the way his t-shirt was tight enough to reveal his muscled chest. I also couldn't help but notice how smooth Sydney's legs looked, and how her eyes sparkled as it reflected the LED light from the screen.

Syn looked away from the screen, catching my stare. "You're going to lose if you do that," she said with a little smirk on her face.

With an embarrassing squeak I returned to the game. Tyler won that round, causing him to grin widely at Syn. "Yeah, yeah, gloat all you want. I want to go again!" she demanded. As we selected the course she moved over from her spot on the lazy boy and came to sit by me on the couch, snuggling way closer than she needed to. When Ty gave her a raised eyebrow, she threw an arm around me and sang, "She's gonna be my good luck charm." I couldn't see her face as she faced toward her bf, but I'm guessing she was making a suggestive face because my brother flashed her a "chill out" sort of look, which she probably ignored.
