Chapter One
"So you dropped out?" my twin sister, Marina, asked from behind me, where she sat on the edge of my bed. I was sitting in front of my pc finishing up some coding I had been working on for an indie game I was developing. I sighed and turned my chair to face her. She sat cross-legged on the edge of my bed in a pink shirt that hung about mid-thigh. Her long legs were bare except for a pair of thigh-high fuzzy socks. I eyed her silently for a bit, then nodded, turning back to the screen to save my work so I didn't fuck up an hour's worth of coding.
"You remember what Dad said when he agreed to pay half our rent, Sy?" She always used the shortened form of my name when she was annoyed. My name was Sylas to her--unless she was annoyed, in which case it was Sy.
"Yes, Marina. I remember. Dad would only pay for half the rent if-"
"We both were working or in school. And you dropped out." She said, cutting across me. While it was true I had dropped out of school, I had done it for a good reason.
"Come on, Marina. I dropped out so I could focus full-time on this game. Among other things."
"That's a stupid reason." She said.
Well, I had thought it was a good reason.
"Apartments in Chicago aren't cheap if you didn't notice, brother mine."
My sister and I had graduated high school four years ago and took a year off. We were accepted into Northwestern University and decided to move in together since we were in the same school. Marina was working on her law degree, and I was taking management courses. Our father was a big-shot money guy back in New York City, and he wanted me to follow in his footsteps. I couldn't think of anything less appealing. He had paid our first two months, then said he would pay half the rent and let us handle the other half with the stipulation that we both had to be working or in school.
Marina and I had always gotten along. Our mother used to say we were the same soul born into two bodies. That could be true. We were as close as anyone could be. Her current boyfriend, Mike, got annoyed at how much time we spent together. Fuck him. She was my best friend and my favorite person in the world. However, she could also be the most annoying person in the world.
"Yeah, I know. I'll put more time into my game but can do something full-time. Jason has been begging me to do some coding at his game dev studio." Jason was an old friend from high school who had kept in touch. He started a video game development studio shortly after high school. Jason had done alright and released a game shortly after forming that had gotten a bit of buzz from video game media outlets that summer. I even saw it on the Steam Discover page. It had solid reviews.
"Maybe," my sister said. She was quiet for a bit, then groaned and sat up. "I suggest you call him and take him up on his offer. Once Dad figures out you dropped out of school..." She let her sentence hang as she slid off the bed and stretched, stifling a yawn. Her T-shirt rode up her thighs a bit as she did, showing off her panties. The panties in question were lilac-colored and incredibly sheer. I looked away hurriedly as I realized I could make out her vagina through the fabric. I felt her come up behind me, wrap her arms around my neck and hug me. She held the hug for a bit, and I put a hand on her arm and patted it. She kissed me on the top of the head and then patted it briefly.
"Well, I'm going to bed. Don't stay up too late. Mom wants us to meet her for brunch downtown. I'll be damned if I go, and you sleep in."
I mumbled an affirmative noise and went back to coding. A minute passed, and I heard the door softly click shut and turned to look. I smiled at the closed door and turned back to my computer.
An hour later, I leaned back from the desk and stretched. Looking at the clock, I sighed, turned my monitor off, rose from the computer chair, and entered the hall. My bladder was so full it might burst, so I headed for the restroom down the hall. I stopped by my sister's room momentarily when I heard a noise. It sounded like she was sobbing or something, so I approached her door. The door was slightly ajar, and a faint light fell through the crack into the hallway. I peered through the crack, and my eyes went wide. My sister was lying on her back on the bed, naked from the waist down. Her t-shirt was bunched up over her tits, and she was rubbing her clit with a vibrator. As I watched, her legs began to shake, and she pushed two fingers into her shaved pussy. A few seconds later, she groaned, and her toes curled. Her fingers were pushing in and out of her pussy. As I watched in stunned wonder, liquid began pulsing out onto her bed as she started squirting with her orgasm. Holy shit, I thought as I hurriedly left the doorway and made my way to the bathroom. I quietly closed the door behind me and leaned against it, breathing hard. I caught my sister masturbating. Jesus. I finished urinating, washed my hands, and returned to my room. As I left the bathroom, I noticed her door was now closed.
As I lay in bed staring at the ceiling, I soon realized I couldn't fall asleep. I felt keyed up as I beat my pillow into a more comfortable shape, but nothing helped. Finally, after looking at my phone and seeing the time was almost 1 a.m., I kicked my covers off and turned on my bedside lamp. I slept in only my boxers, and they were tented around the shape of my rock-hard cock right now. I grabbed at my erection and sighed.
Maybe jerking off would help me fall asleep. I slid my boxers down over my hips and threw them on the floor, and grabbed my cock. I began absently stroking it as I reached into the drawer on my bedside table and took out a bottle of lotion. As I rubbed a generous supply of lotion on my cock I took a moment to appreciate it. Hard, it was about 7 inches in length and relatively thick. It was not huge by any means, but I liked it. I grabbed my phone off the charger on my bedside table and went to a regular porn site I used, and settled in, gripping my now throbbing cock in my fist.
My hips left my bed as I began sliding my fist up and down my slick shaft. My breathing came heavier as my balls contracted. I could feel my orgasm coming and began pumping my cock faster. I finally closed my eyes as a moan escaped my mouth. My mind wandered. My sister, in her room, pussy in the air with her fingers pumping in and out as she groaned and began squirting. My eyes shot open as ropes of cum started shooting from my cock. I stifled my moan and began pumping my fist faster as I felt cum shoot so high it hit my chin. I slumped into the bed as my orgasm abated and reached for a tissue to wipe the cum away. What the fuck was that? I asked myself. As my air conditioner kicked on, I rolled over in my bed and pulled the sheet over me in the heat of a July Chicago night.
It wasn't weird to have a sexual thought about your sister, I self-reasoned. I'm sure all guys have those.
'Do all guys shoot loads of cum thinking about their sister cumming?' Came a thought from the back of my mind. I grabbed my pillow and stuffed it over my face as I loudly groaned. UGH. I finally rolled over and tried to drift off to sleep.
The alarm on my cell phone woke me up. I lay there for a few seconds, staring up at the ceiling. I was replaying the events of last night in my mind. I eventually rationalized it by thinking that any guy my age would get worked up over seeing something so sexual. It didn't mean anything. With that moment thoroughly rationalized, I sighed, got up from my bed, and went into the hall to the bathroom. The door opened, and my sister came out. She was wearing a towel and still wet from her shower.
"Oh, you're up. Good. Get a shower so we can meet up with Mom. You know how she gets if we're late." She bumped her hip into me and smiled as she passed me. I rolled my eyes and swatted her with the shirt I was carrying, and she yelped and hurried into her room, the door shutting softly behind her. Ten minutes later, I exited the shower and went to the kitchen, where Marina ate some toast while scrolling on her phone. She wore a black tank top and faded black jeans stuffed into her usual Doc Martens. Her hair, long and raven black, was pulled up in a high ponytail today. We tended to dress the same--a lot of blacks and dark colors with the occasional splash of color on her part. A small blob of strawberry jam sat on the edge of her lip. I grinned and wiped it away from her face.
Ten minutes later, we began our trek to her car. She had decided we would take her car. She would drop me off here and head to her boyfriend Mike's house. A strange feeling came over me when she mentioned him, but I was too busy ensuring I had my keys and wallet to analyze it. The summer air slapped me in the face, causing my eyes to water. It felt like looking into an oven. As she turned to lock the door, I briefly toyed with the idea of going back into the apartment to put on shorts instead of jeans but decided against it as I hurried to the car. As she slid behind the wheel, her tank top pulled up a bit, revealing the skin of her hip. Without thinking, I reached out, grabbed her hip, and squeezed.
"Hey, you jerk. What was that for?" Marina pouted at me in mock sadness from the driver's seat. The moment I had gripped her hip, a strange look crossed her face for a split second. I peered over at her, then smiled.
"Who knows? Maybe you're just super pinchable." I said, and she swatted my shoulder before pulling out onto the street. About an hour later, we pulled into the parking lot in front of the restaurant our mother had picked for us to meet her at. Our parents had moved to Schaumberg a couple of years back from the city. Mom said it was due to Dad's commute to New York, but that didn't make sense as O'Hare was only about a ten-minute drive from where they lived in the city. Marina and I felt it was Mom's choice to leave Chicago. She had always been one to take crime statistics and police reports to heart. Looking over, I saw Mom's Mercedes parked nearby.
Our mother was a fine enough mother. She loved us, and we knew it, but she could be overbearing. She had flipped her lid at the thought of us moving out, especially when Marina also decided to move out. She settled down when she figured out we'd be moving in together. Marina pulled the rearview mirror down and ensured her hair and makeup were fine before exiting the car. She linked her arm with mine as we made our way in. The inside of the restaurant was nothing fancy--a typical Midwest sit-down family-style diner. As we waited on the hostess, my sister patted my arm, which she still held onto.
