Introduction:

This is my first story, so please bear with me. It's not very descriptive. **This is just part one**

It was an early afternoon, and I was sitting on the couch playing a few games on my Xbox. I had only recently got into gaming, and was hooked. I was playing when I heard a knock on our door. Our 2 bedroom apartment was quite small, and the slightest sound made the whole house echo. My mother went to answer the door, and my 18 year old sister, Vanessa, emerged from the hallway. We exchanged "Hey's," and she layed down on the sofa next to me. We began to talk about school, life, and how things were. After a while, she fell asleep. Nerdy me was playing Crackdown.

I was playing when I looked over to my sister. She had a gorgeous face and body. She had curves to die for, blonde hair, and bubble-ass that looked like it was about to burst right through her jeans. She was wearing skinny jeans, and a top that showed off some skin. She was facing the TV, and was sound asleep.

I started to realize how gorgeous my sister really was. After a while, I noticed I was paying more attention to her than my game. I was unaware of my surroundings. My parents were asleep just down the hallway, and her boyfriend was nowhere to be found, so I had a feeling she was staying the night (score one for me).

I guess she was awake for a while, because she started to shift, and hit me with a "Can I help you?" I simply replied, "Sorry sis, I just forgot how beautiful you are." She blushed and started to drift back to sleep, apparently not caring I was staring at her. I looked down and realized my dick was starting to grow to its 7 inches, very noticeably bulging through my pants. I realized it was going to be 'never goes away' boner, so I thought I had to take care of it right away. When I looked back at Vanessa, I found her legs completely turned away, but her face was sort of looking downwards at me, at my pants. Her hand was almost jerking a bit. I ignored it and thought she was just messing around, and hurried to the bathroom before she noticed something, when she stopped me in my tracks.

"Taking care of something?" She asked. "Just going to the bathroom." "Sure you are. Come over here and sit with me." I hesitantly started to make my way over to Vanessa, attempting to subtly cover my raging boner. "Need some help?" She whispered. "No, I'm fine, thanks." I started to turn red from embarassment (who wouldn't?). She slammed me down onto the sofa, and without warning, started rubbing my jeans. "I saw you looking at me, Robert. You aren't very subtle." She stated. "Sorry, but who wouldn't stare at you dressed like that!?" "Shut up and unbuckle your belt, and pull down your drawers." My sister easily overpowered me, as I was shocked by what was happening. I did as she said, but stopped at my boxers. "Too scared?" She said, "I'll do it then, pussy."
So here I was, my 7 incher sitting out in our small living room, with my sister, within 20 feet of our parents room. My sister proceeded to then take my cock in her hand, and start jerking. "Please tell me you're not a virgin, lil' bro." "I-uh-I-I" I stuttered. "That's what I thought. Well, I'm going to be a good sister, bro." She said sexually. Instead of jerking my cock in her hand, she started to put her head downwards. Before I knew it, she was licking my cock like an Ice Cream cone. Not long after, she popped my cock head, and eventually tried to suck my cock down. "Damn, you were given a good gift. Most guys I suck are about 5-6 inches."
Vanessa started to bob her head up and down. Suddenly my brain shut off reasonable mode and I grabbed my sisters head with force. I shoved her head down until she gagged on my cock and I felt her moist mouth enclose my dick. I didn't stop when she gagged, I kept going. I could feel her throat loosening up to my fat cock, and before I knew it, I could feel pressure on my dick.
I was getting ready to cum. I yanked my sister's head up and violently whispered in her ear, "Suck my cock like the slut you are, and let my hot cum ooze down your throat while you gag on my manhood." I shoved her face back down. I felt my cock drip pre-cum, and before I knew it, I was close to orgasm. My sister could feel it. She sucked harder and harder, and that set me off. "UgggGGGghhhhHHhHg" I groaned as my sister swallowed every drop of my hot seed into her belly. "Holy fucking fuck sis, I didn't know you had that much of an amazing skill!" She blushed. "Welllll, I don't mean to brag but I have some experience." She then winked at me. After that, we said nothing. It was absolute silence for about 5 minutes. Then, for the hell of it, I leaned over and kissed my sister hard on her lips, tasting some of my leftover cum on her lip. She then kissed me hard on the lips, and we both had each others tongues in our mouths. We must've been making out for a while, because before I knew it, it was 2 AM. After making out, we started to play with each other. We were doing the unspeakable. Then we both heard a door creak open.
