I was 20 years old and had just finished my three year contract with the army. I was a little nervous pulling into my friend Dillion’s driveway. I had not come home on leave once, I spent most of my three years in Iraq and had only exchanged emails with him but he was having a welcome home party for me after a football game.

There was already at least a hundred people there and it did not take me long to find my friend. Dillion and we stood away from the main crowd of people trying to get caught up and get a new feel for each other. He did most of the talking as I looked around. There was a bonfire, five kegs and a lot of high school kids.

“How was it over there?’ Dillion finally asked the inevitable question.

“It sucked,” I replied then took a long drink of my Corona so he wouldn’t ask anymore questions and that was when I saw my seventeen year old sister for the first time since I had been home. Kalley had shoulder length blond hair, greenish blue eyes, big tits and the nicest ass I had ever seen. She was wearing a white button shirt and a blue denim skirt that barely covered her ass.

I looked around to see if anyone was near. “God damn Kalley is fucking hot!” I exclaimed. I knew I could tell Dillion this because before I left I had helped him bang his older sister Danielle and from his emails I knew that they were both going to a college in a different state and everyone there knew them as boyfriend and girlfriend.

“Yeah she is.” Dillion laughed and that was all that was said about it.

I couldn’t take my eyes off of Kalley. She was fucking gorgeous! She carried around a pint of rum and a beer. She flirted and danced with every guy and made out with several. Then I realized my little sister was just a little party slut. The thought of Kalley getting fucked made my dick hard and I started looking for aa little hottie to abuse.

As the night wore on I was reunited with old friends and my little sister and at about midnihgt I remembered that Dillion always had a sort of raffle at his parties for his closest friends. Everyone would put their name in a jar and sometime after midnight Dillion would draw a guys and a girls name out and discreetly lead them to the guest house where the lights woud be off and they would spend the night fucking each others brains out not knowing who they were fuckign until morning.

This game brought us all much enjoyment and we never talked about it except with each other or made fun of anyone for having to hook up with someone they wouldn’t voluntarily. The rules were very simple. Dillion would come find each person and lead them to the guest house. He would not broadcast who was fucking whom but in the morning if they chose they could come out together. The guys could not speak but the girls could and in the morning when it was light enough to see you had to fuck one more time when you knew who it was you were fucking or you weren’t allowed at anyone’s parties.

I saw Dillion walking towards me and I knew that he was doing me a solid and letting me fuck some hottie he had handpicked. I pounded my fist to his and looked at the guest house. Dillion had done this for me in the past, letting me fuck a couple popular girls in our school that were stingy with giving up the pussy.

“I got a really hot piece of ass all naked and waiting to get fucked just for you bro,” Dillion said with a smile. “Welcome home.”

All thoughts of my sisters tight little ass vanished as I realized I was going to get laid for the first time in over a year. The guest house was small with a bedroom and a bathroom. I had been in there hundreds of times so I knew my way around in the dark. I locked the door behind be and stood there for a few moments to let my eyes adjust. I had forgotten how dark it was in here with the curtains pulled.

“Come over here I want to suck your cock,” I heard the slightly drunk voice of my sister Kalley. I silently thanked god for giving me such a good friend as I ripped my clothes from my body and made my way to the bed. I could just barely see the dark outline of my sister sitting on the edge of the bed and I almost tripped on her clothes on the way there.

My cock had never been so hard.

Kalley jumped when I ran my hands on either side of her face. She instantly raeched out and started stroking my dick but I wanted to kiss her first and pulled her to her feet. Still cupping her face I kissed Kalley hard and grabbed her ass roughly. Kalley must have liked it because she moaned as we continued to kiss.

Kalley broke off from our kiss and sat back on the bed. I took a small step forward and she swallowed my cock. I moaned loudly repeatedly. I couldn’t help it Kalley was giving me the best blow job of my like. AS her head bobbed forward on my dick her hand would twist in front of her mouth and I had to stop her before I blew my loud.

I pushed her onto her back and Kalley climbed backwards on the bed. My dick was doing the preliminary throbs the came before an orgasm so I walked over to the sink and filled up a glass of water. I took my time drinking it until I had control of my pussy hungry cock. Then I thought about the way my sister moved when she was dancing with guys around the bonfire I climbed on the bed and between my sisters legs.

“I like it hard,” Kalley told me.

Good, I thought. Because I was going to do everything imaginable to her before the sun came up and she freaked out. Five hours should be enough time.

I felt my way in the dark and rubbed my dick up and down her slit until I found her love hole. I pushed the head of my dick in and felt her feet behind my thighs. I couldn’t wait another second and I thrust as hard as I could.

“God YES!” Kalley screamed as I fucked her as fast and as hard as I could. I hooked her left leg over my shoulder then her right leg over the other.

“FUCK ME! FUCK ME! FUCK ME!” Kalley screamed and I was delighted at what a little whore my sister had turned into while I was away at war. My family and Dillion had sent me pictues of Kalley while I was deployed. The pictures Dillion sent were of Kalley wearing little or no clothing and I had told the guys in my platoon that she was my girlfriend and beat off to them nerly everyday.

I grabbed the head board so I could pound her harder and her screams got louder and there was animal like noises coming from her throat. In the dark I could barely make out the outlines of her face. And she clawed my back hard as she had her first orgasm.

“DON’T STOP FUCKING MMMEEE OUT SSSHHIITTT I’M CCCCUMMMIINNNGG!!!” Kalley thrust her hips up savagely and her head side to side as she climaxed. Her tight little pussy clenched my dick so hard that I blew my load deep into my sister.

Out of breath I rolled off of her and she leaned over and started kissing me while she jerked me hard again.

“I am going to ride you until you cum.” Kalley told me and I smiled as she lowered herself onto my dick. This was without a doubt the best sex I had ever had I thought as she rode me back and forth fiercely for about twenty minutes.

Kalley didn’t say a word as she rode me like a pro and she climaxed again and again before I finally blew my load for the second time. Kalley collapsed on top of me and we both passed out.

When I came to Kalley was still on top of me but I could see through the moon roof that the sky was beginning to lighten and I only had a short time to fuck my gorgeous sister. I ran my hands over her tight little body and she began to stir. I bit her neck hard.

“That feels good,” Kalley moaned and just like that my dick was rock hard again. I pushed Kalley off me and into the doggie positon. There was a little light so I didn’t have any trouble pushing my cock into her wet pussy.

Kalley let out a wordless scream as I once gain thrust into her as hard as I could. She bucked back against me and threw her tossed head around every time I pounded her. I slowly reached forward to grasp her hair and once and had a fist full I pulled back as hard as I could.

“OH FUCK! OH GOD!” Kalley growled. It was light enough to see that I was fucking my beautiful sister doggie style and I knew that soon she would want to see she had fucked so I slowed the pace to keep her from having an orgasm so that maybe she would get caught up in the moment and finish fucking me before she realized she had committed incest.

Kalley’s face was on the bed as she rested on her elbows when she spoke. “I am going to roll over and I want you to keep fucking me.”

I pulled out of her so she could roll onto her back. I heiredly got into position between her legs as her eyes adjusted. I had my dick at the entrance of her pussy yet again when I saw her eyes widen in shock and horror.

“Oh my god Joe?!” Kalley gasped and I fumbled my dick around trying to find the entrance to the spot where she wouldn’t tell me to stop once I was in her. “Joe don’t!”

I thrust into her hard and she arched her back in response.

“Joe I’m your sister!” she moaned softly as she rested her hands on my shoulders and gently pushed. I smiled as I lowered my mouth to the spot on her neck that she loved to be bitten on.

“Oh god JOE!” We began to get a nice rhythm as I moved on top of my sister. “We should be using a condom.” Kalley moaned.

“It’s too late Kalley,” I said looking down at her. I kept fucking my beautiful sister and could tell she liked it. She nodded in agreement and began fucking me back. “Tell me you want me to fuck you.’

“Fuck me Joe!” Kalley commanded with a wicked grin and I began fucking her as hard as I could. “THAT’S IT! YOU FUCKING PERVERT FUCK YOUR LITTLE SISTER! FUCK YOUR SISTER HARDER!”

I was once again amazed at the sluttiness of my sister as I could clearly see the expression on her face as she had another orgasm. I always she that face when I think of Kalley now.

“Do you want to fuck your brother you fucking slut?”

“OH GOD YES! I WANT TO RIDE YOU HARD!”

I rolled us over without taking my dick out of her tight hot pussy and she began riding me just as hard and as fierce as she did earlier.

“You like getting fucked by your sister?”

“Fuck yes your pussy is so fucking tight!”

“You want me to hop on your dick?

“God YES!”

Without another word I watched as my beautiful sisters tits began bouncing up and down as she changed her motion and began hoping up and down on my dick!

“OH GOD JOE! I WANT TO FUCK YOU EVERYDAY! OH GOD I AM GOING TO CUM AGAIN!”

I couldn’t take it anymore and when I felt her muscles contract I blew my load deep inside her. It felt like I would cum forever and she rested her hands on my chest and moved against me as she pumped my dick clean of semen.

When she was sure I was done she rolled off me and grabbed her clothes.

“We have to get out of here before anyone sees us, Joe.” She said my name differently now and I knew it was because we were no longer brother and sister. Now we were lovers.

“Do you need a ride home?” I asked as I quickly pulled on my clothes.

“Yes,” Kalley answered

Neither one of us said a word the whole way home.
