When I was 15, my new step-sister, Christie moved in.  She was about a year and a half older than me.  At first I was pissed because now I had to share my home, all my toys, and attention with her. But soon, I realized how lucky I was. Christie was a beautiful brunette with and thin athletic build. After a few months, we became pretty close friends.  We would watch TV together and play cards on the family room floor.  Sometimes she would knock on my bedroom door at night because she couldn't sleep, and we would go to play some games. She usually wore pajama bottoms and a T-shirt. Nothing too revealing, but I could see she had a sexy body under those clothes!

When the weather got warmer, Christie would wear shorts and a light shirt when we played our games.  One night, things changed between us.  We were getting ready to sit on the floor and play our card games. She had on a pair of loose fitting gym shorts, and an oversized, baggy T-shirt.  I was already on the floor shuffling the cards when she started sitting and I could see right down her shirt. I had a quick glimpse of her perfect tits. No bra, all tit!  But the best was yet to come.  When she sat down, Indian style, her furry little pussy was exposed from the side of her shorts.  It was just sitting there, for the whole world to see. Such a pretty pussy, too! Perfect pink lips, exposed clit, and the whole thing was framed by beautiful curly pubic hair.  Christie didn't seem to notice, either. We played cards for about a half hour with her pussy out.  I was having a hard time concentrating on the game.  Sometimes she would shift her butt to get more comfortable, and I could see her pussy spreading open and closed. It got me so turned on, I had to put a pillow over my lap to hide my boner! When she would reach for the cards, I could see right down her shirt, too.  I started to think that she was doing this on purpose and wanted me to do something about it, but I was too shy and awkward to do anything but stare.

After a couple of games, she got up to go to the kitchen for some snacks.  Once again, I saw right down her shirt. When she came back, I noticed she had panties on. So maybe she figured out that she was flashing me, but she never said a word about it. Once we got playing cards again, I could still see up her shorts, and see a little bit of her pubes sticking out. It was still quite a site! I had to put the pillow back on my lap!

We played cards often, sometimes with panties, sometimes without. The only constant was me jerking off later that night thinking about my step-sisters beautiful pussy. One night, we were in the middle of a great game of Monopoly.  She had these pretty little pink panties on. She said she had to go to the bathroom, and we took a break. When she came back, her panties were gone!  I could tell she had shaved since the last time I gazed apon her pussy. Not totally shaved, but she had left a nice tuft of pubes over her smooth vag.  We played the game for awhile, with her shifting back and forth, foward and back, moving her pussy lips around for me to see.  When the music we had on would make her feel like dancing, her pussy was jumping around so much, I almost came in my pants under the pillow. I could actually see a glistening on her lips, like she was getting wet and turned on!  Once again, I couldn't concentrate so good on the game, and after a couple hours of my pussy show, she beat me at Monopoly.

It was getting late, so we went to our separate bedrooms.  I knew I was going to jerk my dick so hard, I may rip it off!  I got my skin mags from under the matress, took off my pants and climbed into bed.  I saw an upshort picture in the magazine and started to stroke my dick.  Then there was a knock at the door.  Of course it was Christie.  I put the mag under the blankets and told her to come in.   She sat on my bed next to me with one knee up, and the other leg on the floor. I emidiatly saw her perfect pussy coming out of her shorts.  She told me she was having a hard time falling asleep after our exciting game.  She probably said all kinds of things, but all I could do was think about her naked pussy on my bed with me being naked under the blankets with a raging hard-on.  At one point she noticed me staring at her crotch, and said, "Oh, excuse me".  I said, "No big deal, Sis, it happens". She went to adjust her shorts, but actually rubbed her pussy instead. She said that felt good.  "Do you mind, Bro? It's helps me fall asleep".  I couldn't even say a word! She was touching herself, looking at me with these sexy eyes, and reached over with her other hand to touch my boner over the blankets.  She started fingering herself, and I could hear her pussy juices popping as her finger slide in and out of her pussy. I pulled the blanket off of me, keeping the nudie mag covered, and she grabbed my cock.  Then she said, "Can you keep a secret, Bro? I figured out that I was showing my pussy during the game tonight, and got all excited thinking about it. If you promise not to tell ANYONE, I'll play another game with you tonight!"  "UhUhUhUh, sure Christie" was all I could say.

She held my dick so tight, stroking up and down. "Nice dick, Bro. Do you want to touch me?" I reached foward and tufted her pubic patch, then moved my fingers down to her wet pussy.  I ran my finger up and down on her pussy lips and slid one finger inside my sister. She gasped. All of the sudden, she jumped up off the bed, stripped off her shirt and pants and pulled the covers off of me.  Luckily my porno mag fell on the floor with the blanket.  She went to the bottom of the bed and crawled between my legs, kissing along the way until she got to my dick. She stroked my hard dick, licking my balls, and staring up into my eyes.  She took my cock head into her mouth and started sucking so gently.  She said she wanted to try something, and put me all the way into her mouth. She gagged just a little, but kept deepthroating me.  She was rubbing my thighs, sucking my dick, and still looking up into my eyes. This was freaking incredible!

I told her that I wanted to try something. I helped Christie to spin around on the bed and positioned her pussy over my face.  I could smell the sweet scent of my sister hovering over my mouth.  She adjusted to put my cock back in her mouth and colapsed her pussy onto my tongue.  My god, she was so wet and tasted so good!  This was the first time for everything for me, and I licked and sucked her pussy with no idea what I was doing. She seemed to like it, anyway, because she grinded her crotch into my face and let out soft little moans the whole time. I started fingering her while I licked away and she kept sucking my dick.  We were both grinding against each other, devouring our private parts.

I knew I was about to cum, and whispered to my sister, "I'm getting close, Christie".  She crawled off of me, reached into her shorts and pulled out a condom. "I stole this from your Father. I hope he doesn't notice."  She tore open the rubber, and rolled it down over my cock. "Is this your first time, Bro?" "Yes" "Mine, too"

She sat on top of me, leaned over and gave me a kiss. Her boobs rubbed against my chest, and they felt so smooth. Then she moved foward and put me inside her.  We both let out a grunting sigh.  At first we moved really slow, just feeling it out.  Then I reached up and felt her tits. When I started playing with her nipples, and started grinding her pussy a bit faster. I was meeting her pussy with my penis thrusts.  Now I was all the way inside my own step-sister, squeezing her tits, breathing heavily. She was looking right into my eyes and making cooing sounds.  Once again, she leaned towards me and this time gave me a long, sensual kiss.  "This feels so good, Bro! We should have done this before!"  Now our pace picked up, and we were fucking so hard, my bed was moving.  "I'm going to cum, Christie!"  In just a few thrusts, I filled the condom with what felt like a gallon of cum!

Christie and I experamented over the next year or so.  We did just about everything, except anal. She was so against that, that even when I was eating her pussy at the park one evening and accidentally licked her butt hole, she jumped and yelled at me.  We bought sex toys to play with, did it in the car, outside in the park at night, and even did it in our parents bed one time.  We would still date other people, then tell each other what we did with them. She turned out to be a great cock sucker! She would blow me any chance we got. She absolutly loved to swallow, too!  She said it made her feel dirty!   

Christie went off to college, and the next year I joined the Army. By the time I got out, she was engaged.  To the best of our knowledge, no one ever found out about us. But we have a special look for each other at the family holidays!
