Everyone in this story is over the age of 18
CHAPTER 1
I'm 21 years old, my name is Chris and I live with my mum, dad and my younger sister Sophie. I never went to University and I work in a warehouse, just packing boxes but it makes enough for me to see my friends and go on the occasional night out.
Being quite geeky I have never had the opportunity to be with a woman, although every night I fantasise about it. I started by watching lesbian porn and then I started to read Literotica where my fantasies just grew and grew. I quickly learned that I was a submissive person and I am pretty sure that I am bi.
I have never done anything with a guy, but the stories of men being dominated by other men seemed to do something to me. Also, the stories of women dominating men hit the spot just as much.
I am only 5 foot 8 and fairly slim, not being confident just made my luck with women even harder. Although I had fantasies of men, deep down I knew I would never act on it.
This was my life. When I wasn't working, I would play games with my friends. When I wasn't with my friends, I usually spent my time wanking to Literotica, thinking of men and women dominating me.
Now my sister Sophie had turned 18 a few months ago, she was the polar opposite of me. I still don't know how we are actually related! She is nearly 6 feet tall, long blonde hair and deep green eyes. I know she's my sister but my sick mind still found her sexy, she was a beautiful woman and was out going. Truth be told, I was jealous of her. I wish I had an ounce of her confidence.
Sophie has been dating Terry, he is my age and we actually went school together, except he was on the rugby team and one of the most popular guys. He didn't even know my name the first time she brought him home even though we went to the same school for years.
A lot of the time my mum and dad would try to encourage me to be more like Sophie, go out and get more friends and be more active but that just wasn't me.
One night we were all sitting together having dinner when Sophie told our parents that she was going out this weekend with her friends and with Terry when my mum said, "Why don't you take Chris?"
"No chance! He would just embarrass me!" Sophie argued back.
I just kept my head down, knowing she was probably right.
"Don't be mean to your brother, take him with you." My mum argued back.
"But we are going to a party, he won't know anyone. He will hate it there!" Sophie moaned.
"Sophie, do as your mother says." My dad chimed it.
"I don't want to go." I finally spoke up for myself.
"It will be good for you." My mum said.
I didn't look at her, there was a brief moment of silence before Sophie grunted in agreement.
After dinner, it was my turn to clean the dishes when Sophie came in.
"If I am having to take you with us this Saturday, just don't do anything stupid okay?" She said.
"I don't even want to go." I told her.
"I know but mum doesn't care. Just dress nice and try and act normal." She said before storming off.
I turned around and got a glimpse of her leggings that hugged her curvy arse perfectly, before realising I had a hard cock.
Cleaning up quickly, I made it to my room and loaded up Literotica. My sick mind in full flow I read some incest stories and started wanking. Looking online I was pretty confident that my cock was a good size, at least 6inches. If only my confidence would show in real life! Within a few minutes I had covered my stomach in cum, cleaning it up I went online and started to play with my friends.
CHAPTER 2
Here it is, Saturday night. I was getting dressed, putting on a black, buttoned shirt and my blue jeans and a pair of black trainers. I jelled my short brown hair to the side and went downstairs.
I met with Sophie, her blonde hair was straight down, she had on a short skirt and a black crop top that emphasised her big tits. I had to try and stop myself from getting a hard on by just looking at her.
Next to her was Jerry, a tall, muscular man. He was in a tight white t-shirt and blue jeans.
"You're wearing that?" Sophie asked in a huff.
"What's wrong with it?" I asked.
"You look like you're going for a job interview." She moaned, "Urgh, whatever let's go."
Walking outside, we got into Terry's car and drove to the house party. I was sitting in the back and Sophie and Terry were chatting in the front.
Before arriving, Sophie turned around to me and said firmly, "Right, whatever you see in here does not get back to mum and dad! I don't want you telling them anything about me drinking or anything that goes on. You got that?"
"Sure." I moaned back already knowing I am going to hate this.
As we walked inside the room was dark and there was loud music blaring so I couldn't hear a thing. The house was packed with people, the handful I recognised were Sophie's friends that didn't acknowledge me. Most of the girls were dressed in very little clothing and the guys all looked like typical cool guys.
"I'm getting a drink, do you want one?" Sophie shouted over to me.
"Yes." I shouted back over the music and watched as she went to get a beer from the table that was filled with bottles and cans.
For the next hour, Sophie and Terry actually stayed with me and I appreciated them not just leaving me on my own. Until I looked at the clock and saw it was midnight and I realised that they weren't here.
Sitting on my own on a sofa in the living room I just looked around at everyone having a great time.
I did question, why am I not like this? I could be fun and enjoy myself, but I just don't enjoy this.
Standing up, I made the decision to go to the bathroom before getting a taxi home. It was difficult to get through the crowd of people, the room stank of smoke and alcohol but eventually I managed to get upstairs, except I had no idea which room was the bathroom.
So, I tapped a stranger on the shoulder and shouted in his ear.
"Where's the toilet?"
"Through that door, it has an ensuite!" He shouted back and nodded towards a door.
"Thanks!" I shouted back and headed over.
Opening the door, the room was pitch black and all I could hear was the blaring music coming from downstairs.
As I ran my hand up the wall, I eventually found the light switch and turned it on. That's when I was met with utter shock.
Looking up, on the bed I saw Sophie, completely naked and riding Terry who was naked below her. They were either too drunk to notice me at first or just didn't care.
For a brief few seconds, I saw my younger sister, her big tits bouncing in the air as she moaned extremely loud as her face was in pure extasy. It was an incredible sight, she was so hot and my cock immediately got hard.
Then she realised it was me.
"Chris what the fuck?!" She shouted jumping off of Terry and then I saw his cock, the only other cock I have seen in real life. I couldn't properly see it but from here it looked about the same size as mine, with a slight glisten of Sophie's pussy juices on it.
"Get out you fucking perv!!" She shouted.
I turned and saw she had covered herself in a duvet.
"S-sorry!" I stuttered out, "I'm just looking for the bathroom." Yet I still stood there looking at them both.
Terry was just giving me a smile and said, "It's in there." And pointed to the door to the ensuite.
Rushing in, I closed the door and pressed my back against it. I can't believe what I just saw, my sister completely naked having sex. She was so hot!
Going to the toilet, I tried to get my cock soft again but it was no use.
Eventually, I had to leave. Opening the door, Sophie was sitting on the bed next to Terry and they were both covered.
"Right, get out." She shouted.
