It was Saturday morning, and I was just getting home from spending the night at a friends. My parents were out of town for the three day holiday, and I was supposed to stay at Tim's the whole weekend, but I decided against it. Tim's girlfriend showed up and decided she wanted to go out, alone.

I threw my gym bag into my room and headed for the kitchen. There was a sound upstairs. My sister was old enough to stay at home, while mom and dad were away. It was still early in the morning, and I figured Cindy was just getting up.

I had spent alot of my time, trying to get peeks of her while she took a shower. What do you expect from a fifteen-year old? I remember the time I was able to get a picture of her as she stepped out of the shower. I had convinced her that the camera was empty, and that I was just trying to tease her. The picture is still under my mattress.

Cindy is built. She had the long legs that I always heard Tim's big brother talk about. Her ass was firm and small. Her pussy had just the right amount of light blonde hair, that didn't quite hide the lines of her mound. Her tits weren't large, I'd seen tits of the women in magazines. Large ones just turn me off. Her face and hair were perfect for her body. I used to jack off while looking at her picture.

I walked quietly up the stairs, hoping to see a little more than I had in the past. As I walked down the hall, I heard more sounds of life. Her bedroom door was open. I stooped down low and looked around the sill. I couldn't believe it.

I was looking straight between my sister's legs as she lay naked, sprawled on the bedroom floor. She couldn't see me though, because, sitting right over her face, with her back to me, was one her best friends, Lisa, bare naked.

I watched for a moment as Lisa, her red hair swaying as she moved back and forth. I listened as both girls moaned. They were not new at this. My eyes drifted down to my sister's cunt. I'd never really gotten a chance to see her full slit, but now, I was watching it as it glistened wet.

I pulled back, not wanting to be seen. Slowly I creeped back downstairs. There was alot to fuel my fantasies.

As soon as I was in my room, pulled off my clothes and grabbed my stiff cock. It was bigger than I had ever seen it before. I had never had such a hard on. As I pictured the two girls in my mind, I stroked myself. It wasn't long before I cut loose. I lay down on the bed and let my mind wander through all the possible fantasies a 15 year old can have.

I must have layed there for half an hour before I realized that I had left my bedroom door open. I turned my head, just in time to see Lisa step in through the door.

She stood there, fully naked. Slightly wet. Her red hair fell, in a light curl to her shoulders, and a small twist hung over her small, breast. Her left hand brushed at the curl, then fell towards her pussy. That's when I noticed.

There was no hair covering her little, slightly plump pussy. It was completely shaven and smooth. I had never really seen a girl of her age with a bare cunt, and I was kind of surprised that it turned me on.

Before I could sit up, she moved towards me and sat on the bed. She leaned over me, and placed her hand on my dick. It was beginning to get very hard again.

"Did you come up and spy on us?" she smiled.

I could barely move. I'd never been that close to a naked girl before. I smiled, nervously, and nodded. If I spoke, I would probably stutter.

She smiled back at me and began to stroke my hard on. Lightly, she squeezed my balls. She lifted my hand to her tits and let me feel them. Still grasping my cock, she lay back, away from me. She pulled her legs up and spread them. My hand drifted away from her tits, down her belly, and to her smooth cunt. Her hand guided mine as she slowly moved my fingers around, and into her slit. I took the cue and slowly began pumping her. Her juices flood between my fingers. How could I have been any luckier?

Lisa stroked at my cock. This was more than I could handle. Just as I exploded, I heard a sound of surprise. My sister was standing in the door. She was wearing skimpy panties, and nothing else.

"Lisa!" "Cindy!" "Billy!"

We all spoke at once. For a moment, we all were silent. Then my sister walked over to the bed. My fingers were still stuck in Lisa's cunt. Cindy pulled my fingers out and kneeled down to lick them. Her tongue shot around my fingers, lapping up the juices of her friend.

"Billy, is this what you've been looking for, all this time?" she asked.

Again, all I could do was nod. It was then that I noticed the warm wet feeling around my cock. Lisa was sucking on it. I placed my hand on Cindy's panties, and rubbed. She was warm and wet. She backed off, turned away from me, bent over, and made a little show of taking off her panties. She fingered herself as she slowly walked back to the bed.

With a little shifting. Cindy lay on the bed and pulled my head down between her legs. There, I lapped up her juices. And, Lisa continued to pull and suck at my dick. I felt her fingers wander and poke at my butt. Slowly she shoved her fingers up my ass. With a shattering breath, I exploded my cream into her mouth. She had to know what she was doing.

As she finished swallowing what I could giver her, I heard her whisper to Cindy.

"I want to fuck him."

"Me first," my sister whispered back, "I'm still the virgin here."

Cindy pulled my head up, and pulled me forward. I climbed on top of her. Lisa's hand guided my stiff cock to my sister's hole. Slowly, Lisa pushed me into her.

Cindy's cunt was tight, and warm. I moved up and down, in and out. Cindy moaned as I slid further into her. I pumped harder and harder. My whole body strained.

Lisa was still with us. She stayed back and licked at my balls, then moved up until she was working over my ass-hole. I felt her tongue dart around and try to push itself in.

Just as I was ready to cum, Cindy's hole tightened up, and milked my cock dry.

I had barely let loose, when Lisa was pulling me out of my sister.

"Now, you can fuck me."

Lisa swung around and kneeled on the bed. She looked over her shoulder.

"Fuck my ass, Billy."

Cindy moved, and lay in front of Lisa so that Lisa could clean my juice out of her cunt. I got up behind her and aimed my dick at her small, brown hole. Slowly, and firmly, I pushed my rod deep into her.

"Oh, God, FUCK ME!" she screamed, between cunt laps. She began to pound her ass back towards me. Together we stroked, until I pumped my final ounce of cum into her ass.

Tim could have his girlfriend drag him around the mall. Me, I'll stay home any weekend, and fuck my sister, and any friend she brings home.
