My Weekend With My Step-Sister SeXStoRY

As a youngster I had 2 b*****rs, one a year older and one a year younger. And until I entered puberty I thought that was enough. But when my body started acting differently I knew I wanted more. Thankfully when I was a late adolescent my mother remarried and I earned a step-b*****r and a steps****r. At first they were kind of standoffish but soon we all began to get along great. And thankfully my step-s****r and I seemed to hit it off the best. I think the main reason for that was her b*****r was a lot older than her and treated her like a little k**. However, my step-s****r was the same age as me; just a couple months younger, so we hit it off great. Both of us were kind of young and innocent when we met but our conversations, even as 12-13 year olds leaned towards the more adult theme. When we both graduated high school I am ashamed to say I was still a virgin. And as far as I knew she was too. Her by choice; mine was not. Other than a lot of masturbating when I was younger I had yet to experience the taste of a pussy, hold a tit in my hand or feel a pussy wrap around my young cock. When we were out of school wondering what to do we discussed college and I mentioned going into the service. She did not like that at all since I was now much closer to her than her real b*****r whom she never really liked to talk about; and I often wondered about that. One day we sat at home while the rest of the clan hit the road for a 4 day weekend at our vacation place in Pennsylvania. My s****r and I elected to stay home telling our parents we both had job interviews. My parents were naive… after all, who does job interviews on the weekend? I had no intentions of going to our vacation place just to sit around and watch my step-father fish; something I didn’t like to do. There were no other k**s in the area that were our age so all we would have to talk to were our older b*****rs. And they had absolutely no reason to talk with us. They were always involved in other activities that we were never invited too. So we had the house to ourselves for four days. Thursday evening, the first night after they all left, we ordered pizza and sat around just bullshitting about things. We really didn't do much of anything else. But later that night when it was time for bed I got my first clue about why my s****r didn't like to be with her own b*****r. After taking a nice long hot shower I was returning to my bedroom. Walking passed her bedroom door, which was only open about an inch, I heard her talking and kind of arguing or disciplining someone. Nobody else was in the house so I thought she might be on the phone with someone. Peeking into her door I could see, by way of her reflection in her dresser mirror that she was sitting on her bed. I couldn't see all of her but she was dressed in one of those short “teddies” girls wear. She was looking down at a picture frame and softly but firmly talking to it while poking at it. I listened for a few minutes when I deduced she was talking to a picture of her own b*****r. She was chastising him for being so mean to her and treating her like, as she put it, ‘just a piece of pussy that he could fuck anytime he wanted’. I had never heard her talk like that before nor had I any idea her own b*****r had been molesting her. And up until now I still thought she was a virgin. I was not only shocked but also turned on with this new knowledge. As I continued to watch she threw herself back onto her pillows, still holding his picture. Only now she had the picture pressed up against her crotch saying, ‘There, how do you like my pussy now? Eat me you son-of-a-bitch.” Boy this was really getting to me so I reached down under the towel I had wrapped around me and began to stroke myself. When I saw her slide her hand down to her pussy and begin to finger herself then wipe her finger all over his picture I stroked even harder. But I kind of lost control and during one of my strokes my hand bumped into her door. I saw her clamp her legs shut rather quickly and then looking towards the door she inquired, “Is someone there? Bobby? Is that you?” I quickly dropped what I was doing and tiptoed as fast as I could to my room and quietly closed the door. Standing on the other side of the door I listened as I heard her door squeak open and her call out my name again, “Bobby?” Opening the door I stuck my head out the door and asked her what she wanted. She asked me if I knocked on her door and I made up an excuse by telling her that I was going back to my room after my shower and tripped and accidentally hit the wall near her door. Accepting that bullshit excuse she said thanks and that she thought maybe she heard a burglar. I told her no and that it was just my clumsy ass to which she giggled and then went back to her room. I let out a huge sigh of relief as I closed my own bedroom door. Lying down on my bed I still couldn't get the thought of her saying what she did and also thinking about some of the things she might have gone through with her own b*****r. Some, okay most of those thoughts got my groin stirring again. So I reached over to my nightstand and pulled out a bottle of hand lotion. You know they really should call it ‘hand-job lotion’, as much as I use it only for that. Squirting just the right amount into my hand I smoothed it over my young cock and stroked away. It didn't take too long before I had to reach for that towel again. I really didn't feel like taking another shower when I was done so as I came I shot the entire load onto the towel. Wiping myself clean I tossed the towel onto my side chair, turned off my light and went to sl**p. Friday morning seemed to be just seconds away from when I put my head on my pillow last night. Knowing I had nothing to do on this 4 day weekend I decided to stay in bed a little longer. My room is on the west side of the house so it stays kind of dark in there, especially with the heavy blinds on my windows that keep out the afternoon hot sun and make the room fairly dark most of the day. Laying there in the darkness it wasn't too long before my thoughts went to what I had heard from my steps****r last night. So after pulling the sheet off of me, my hand instinctively went to my groin and started playing. I must have been laying there gently stroking myself for a good 15 minutes when I heard some other noises in the house. Figuring my step-s****r was up now only made my hand work a little faster. I was almost at full staff when I heard a light tapping on my bedroom door and the door handle starting to jiggle. Not saying a word I let go of my dick, pulled the sheet partially over me and put my arm up over my face. Even though my arm covered most of my face I could still peak under my arm and see my entire room. As the door opened slowly I could see my step-s****r walking in. She still had on that little teddy outfit she sl**ps in. She whispered out my name to see if I was awake but I didn't reply; I kept up the ruse of sl**ping. She tiptoed over towards my bed and then very lightly shook my arm again whispering my name. I made a small groaning noise and then moved my legs around which pulled the sheet off of my groin exposing my still half hard cock. I looked up at her as I did this and I could see her attention immediately drawn to my cock. I immediately tighten the muscles in my groin so my cock would twitch and when it did her eyes widened and she bit her lower lip. Groaning a little more as I moved about a little more on the bed I gave my cock a good push with my muscles it grew a bit more and then jumped from between my legs to my thigh. She gave another startled look then slowly sat down on the edge of the bed so she wouldn't “wake me” and as slow as she could she reached her hand out. When I felt one of her fingers touch the underside of my cock I gave it another twitch and once again it grew some more and now stood up against my belly. Reaching out again she touched the soft skin of my balls and as she did I tightened them up to make them move; this time she smiled like the Cheshire Cat. Lightly, she covered my balls with her hand and pulled gently down towards my ass. This succeeded in making my cock, even though it wasn't fully hard yet, stand straight up in the air. I was hoping she would take her other hand and grab it but instead she took it one step further. I watched from under my arm as she lowered her mouth down towards the tip of my cock. She moved around and opened and closed her mouth making believe she was sucking on it. The she stuck her tongue out as if she was going to lick it. When I saw her tongue stick out and it was only about ¼” away from my tip of my cock so I took the initiative to pulse my cock again which made it come in contact with her tongue. To my delight she didn't move away when she felt it touch. Instead she let her tongue circle around the head. This was really nice and my cock loved it too and showed it by becoming fully erect. She let go of my balls and wrapped her fingers around my shaft. Slowly she stroked my cock from the tip to the base while her tongue danced around the tip. Then I watched as her other hand slid down between her legs. Now, from this advantage, I could the teddy she was wearing was only top and she had no underwear on. I watched as one of her fingers slid in between her pussy lips and disappeared into its depth. It was now becoming harder, no pun intended, for me to just lay there and not react to all of this. But I grit my teeth a little and maintained my “sl**p”. Still fixated on her fingers I then felt her lips wrap around my cock and slowly suck it in her mouth while her tongue massaged the underside of it. Oh my God, I wasn't going to be able to stand much more of this “sl**ping”. Somehow I managed to control my breathing so it wouldn't look like I was awake and continued to play possum. As her mouth began to enjoy sucking my cock, more of her fingers joined the first one and slid in and out of her pussy while her thumb played with her clit. I could then feel the rhythm of her stroking hand pick up speed as she now plunged her mouth over my cock almost down to my belly. Sucking as hard as a Kirby vacuum she slowly pulled the length of my cock as her other hand now played around my asshole. Up and down she went, slowly but with strong suction. I could feel my orgasm was coming on and wondered how to handle it. Do I suddenly “wake up” or what? Then, when I felt her mouth against my stomach, sucking the fill length of my cock, I felt one of her fingers push lightly then slide into the opening of my ass and immediately find my prostate and rub it. My mind and my body said enough of this and I began to shoot a large load straight down her throat. As I began to moan and writhe about a little she coughed very lightly as she managed to swallow all of it while maintaining that deep throat position. As the pulses of my orgasm slowed she again sucked up and down the shaft milking all of my juices from me. Slowly she removed her finger from my ass and letting go of her lips from around my cock she got up and quickly tip toed back to the bedroom door. Turning around and taking a last look at me, I made my cock, which was still standing straight up, jump around as hard as I could so it looked like it was cumming again. Once again she smiled and then slipped out the door closing it behind her. I uncovered my face and dropped my arms to my side in wonderment. I couldn't believe what had just happened. I looked down at and grabbed my cock and saw one last drop of cum dripping out of it. Damn, that was great. After waiting until I heard the toilet in the hall bath flush I then got up and after donning a pair of boxers headed to the bathroom to freshen up. As I opened the door and walked in there sat my s****r on the closed toilet seat. She looked at me with a smile and then looking down at my crotch asked me, “Oh, did you have a nice dream last night?” Then nodding her head she looked again at my crotch which made me look down too. I saw my still half hard cock sticking out of the opening in my boxers. Quickly I tucked it back in and like an idiot ran back out and headed to my room. On the way I could hear her giggling out loud so I stopped and turned around and went back to the bathroom. Opening the door once again I stood there holding my cock in my hand and said, “Yeah, I had a great dream that my step-s****r was sucking me off!” Then as I shook my cock at her said, “What are you going to do about it?”. She slid off the toilet seat and went right down to her knees in front of me. “I'll show you exactly what I can do about it!” Then like she had springs on her knees got up, and as she headed out the door turned to me and said, “Nothing… I would hate to wake a “sl**pING” giant! And with a grin closed the door and went back to her room. I stood there with my mouth hanging open. The little bitch knew I was awake all the time. Looking down at my dick once more I noticed it was beginning to revive itself. Softly I mumbled aloud, “Fuck this!” and immediately stormed out of the bathroom and headed for her room. As I threw her door open and was about to tell her exactly what “I” was going to do about it, I looked over at her bed and saw her laying there butt naked with her legs spread eagle. Once again she giggled at me as she tapped her pussy with her hand and said, “You think you can manage to stay awake NOW?” It didn't take me but four steps go get from her door to her bed where I dove straight between her legs and planted my hard cock deep inside her pussy. When we were done I couldn't help but ask her, “Why were you so pissed off at your own b*****r? Did he **** you or something” She replied, “I knew you were watching me. I wasn't pissed at my b*****r for raping me or molesting me while I was growing up… I was pissed off at him because he now had a girlfriend and didn't want me anymore!” Well that really blew my mind. Here I was feeling sorry for her and thought she was an innocent little girl pissed off because she was being taken advantage of by her b*****r but instead she was pissed because she wasn't getting fucked enough. So I looked back at her and while I got my dick hard once more said, “Well, now you have a b*****r that won't ignore you….” And then I got up on my knees and pulled her face down to my cock. We fucked in bed for most of that day and half the day on Sunday. Our parents came home Sunday evening and looked at the two of us sitting in the f****y room just reading some magazines. MY mother asked us, “Gee, it looks like you two didn't have much fun this weekend. Didn't you do anything together?” My step-s****r grinned at me then turned to my mother and said, “Oh no… we just screwed around and did some s****r b*****r stuff all weekend…. nothing special!” I chuckled inside and wondered how my parents would have felt if they only knew………
