It was summer,our parents decided we needed a vacation. I live with my mom and dad and 20year old sister who was at collage, she came home for the summer. She had red hair, blue eyes, yeah imagen that, red hair and blue eyes. She had 32D boobs which any guy would drool over, but she had those long legs, all the way up to her tight, but not to tight firm ass. That would let any man stare twice when she walked the streets. I'm in pretty good shape myself, I have a nice toned body, not too big, but just enough get the ladies, it is probably because I am a swimmer, I love swimming and was on the school's swimming team . I have blue eyes (it must run in the family) and is 16, standing at 5'9" and my sis is 5'6".
So my parents decided to go on a vacation, but me and my sus wasn't very keen on going, I had plans to go dirt biking with some friends at a place we built ourselves. My sis wanted to relax and just hang out with some friends. She had no boyfriend, but I am sure she was no longer a virgin. I had a girlfriend, but she wouldn't let me fuck her, and she left me.
The day our parents left, they gave us a set of rules, don't do this, don't do that and so on. After they had left, I went to get my bike. "Hey James (that's my name) where are you going?" Tanya asked me as I headed for the garage. "I'm going to a Mike's house with my bike, just gonna hit some ramps and so." She looked at me with a smile, I had noticed her before that she was beautiful, but now I see that she is a goddess. "Sounds fun, which friend are you going to?" " I'm going to go Mike's house, then to that dirt bike place which we built ourselves." "Oh cool, that sounds fun. Well enjoy, see you later." She said and went back to the house, she was wearing training shorts and a strapped shirt (she probably went out to jog or something) I stared at her ass as it wiggled as she walked. She disappeared into the house. I got my bike but remembered that my helmet and cloves were in my room. I went into the house and went upstairs to my room. I passed my sisters room and heard a small moan. I didn't pay attention and got my helmet and cloves. I passed her room again, and heard a louder moan. I was now very curios. I went to her door and then I heard her moan again. I peeked trough her keyhole, I saw her laying on the bed, naked, with her one hand on her tits and the other one between her legs. She was fingering HERSELF! Now I masturbate, any boy does, and I knew girls did it too and seen it on the internet, but not like this, not so real and the best part was it was my HOT sister. My cock was now getting hard, but at that moment my cell rang and I jumped. My sister stopped and got up from bed heading for the door. I shut off my phone and ran downstairs quickly. I got on my bike and went as the speed off light of to Mike's house. The day went on and me and Mike and some other friends of us were riding hard. I said goodbye to them, now tired but it was a fun day. But the image of my sister masturbating would not leave my mind. I parked my bike, sawing how dirty it was, made me decide that I need to wash it. I took the bike to the back off the house. We had a nice pool and a bar place where my parents would hang out with there friends. At the back we had a cement space where i washed my bike. I parked the bike and sneaked into the house, not wanting to confront my sister. I went up to my room and changed into some old baggy shorts and no shirt. I went down stairs again, maybe she wasn't home. I went to the garage again and got my cleaning stuff for cleaning my bike. When I came around the house my sister was sitting on my bike, she had a tank top on and shorts. "Hey how was your ride?" She asked me looking at me with her blue eyes. "Um yeah it was great, was fun. "So I had a thought that we might grab a pizza or maybe burgers tonight and watch a movie?" "Yeah sure, I am just gonna clean my bike first, its kind of dirty from all that sand." I said as I went to attach the hose. She climbed off my bike but in a slow way, a sexy way. As she bent forward I saw her boobs hang out a bit and caught a glimpse of her nipples, she wasn't wearing any bra. She went for the house, but she looked at me weird, but in a sexy weird way as she looked at my body. Was she just checking me out? No can't be, not my sister. I shook my head and went on to cleaning my bike. Half an hour later I had cleaned it and was now parking it in the garage. I went to the house to change clothes. My sister was sitting in the TV room watching some reality show. I went up and changed and went back to my sister. "Ok let's go, what do you want, burger or pizza?" I asked her. "You know what, I would like a burger, a cheese burger and some fries. Being a collage student I don't have much time to go out" she said to me. There was a look in her eyes, the same look she gave me outside. " I drive" I said grabbing the keys. We got in the car and went to our favorite burger joint. We ordered our food and drank our milkshakes. The whole time she looked at me in a way that made me feel a little uncomfortable. "Why are you looking at me like that?" I finely asked her. "I don't know, I just realized that you are a handsome young man, and any girl you get would be lucky to have you." She said with a smile. " O ok, um thanks sis." I said quite shy. "So tell me. Did you, you know, ever had like sex before?" I was shocked. I chocked a little on my milkshake. "Well that um,,I um" I didn't know what to say at this point. "Hey its ok, you can tell" she said and took my hand. "No, I hadn't have..sex before" I said looking down. " No need to be ashamed. I know if I was you're girl I would fuck you as many times as I could." She said then realizing what she said. "O ok, um,well.." I was now very shocked at what my own sister said. "I'm sorry, I shouldn't have said that." Just then our food arrived. We ate in silence. The burgers were great, and we went home after getting a movie. "I'm really sorry what I said. And after what happened earlier, I well.." "Wait what happened earlier?" I asked sounding like I didn't know. "Agg come on James, I know you were standing outside my door when I was masturbating. I heard you run down the stairs when your cell phone went off". I was a little ashamed of myself. "Look sis I'm sorry, I didn't see.." "Wait what? You tried to look?" She asked half shock and surprised. "Well no, I mean yes," I couldn't talked to her because I was to embarrassed. She said nothing for the rest of the way home. We got home and I went to change into my pj's which was just baggy shorts and a loose T-shirt. I went down and put the dvd on. My sister came down from her room. She sat next to me. She was wearing a purple shirt and a pair of too small shorts that hugged her ass nicely. We were watching when she said she wants something to drink. I got up and went to get us some sodas. "Do you want some popcorn" I yelled back at her from the kitchen. "Yeah sure" I got us some popcorn and sodas and went back to the room. I gave her her soda and sat down again. She looked at me again, then smiled. "Did you like what you saw?" Came the question. "You mean you and um.." I said turning red. "Yeah did you like what you saw when I fingered myself." She asked me while she softly bit her lower lip. She looked into my eyes, my heart was pumping faster. "The little I got to see was, you know, kind of sexy." I was shocked by my own words. "Do you want to see more?" Without answering her, she took of her top. Her breast were better than I imagend. Her nipples were pink. I looked at them, my cock now starting to rise in my shorts. "Touched them." She said and took my hand and placed them on her left boob. I cupped them and I felt like I was in heaven. I was by this stage rock hard. I felt her boobs with both hands. She let out small moans as I pinched her nipples. I got bolder and without asking I went and kissed her nipples. She jumped but didn't stop me. I took her erect nipples in my mouth, sucking on them. She moved her hands through my hair. I stopped and looked at her. She kissed me, her lips against mine. I again got bolder and opened my mouth while her tong came in contacted with mine. Our kiss lasted several seconds before she broke our kiss and pulled my shirt over my head. I she moved her hands across my chest and abs. I again began to feel her boobs. " I want you brother, I want you so bad. I know this is wrong, but I don't care. I love you and I want to be your first." She said to me. "I love you too sis, I wouldn't want anybody else but you to be my first." She kissed me again. I moved my hand down her. I stopped a bit but she took my hand and placed it on her crotch. I rubbed her trough her shorts. She took my cock in her hands and slowly rubbed it. She got up and took my hands. She led me up to her room. I pushed her down on her bed, making her tits juggle. I looked at my goddess sister in front of me. I got on top of her and kissed her again. I started going down on her. I sucked in her nipples. "Go to my pussy, I want you to eat my pussy." She said breathing hard. I went down to her shorts. There was a wet spot on them, she clearly wasn't wearing any panties. I took of her shorts revealing her pussy. She had a patch of red hair down there, but I could see her pussy lips. She was wet and I could smell the aroma of her pussy. It was intoxicating. I went down and licked her, she jumped a little. I began to use my tong and explore her pussy. The tasted wasn't bad at all, it was very good. I soon found her cilt. I licked it and she let out a moan. I went back, knowing I am doing something right. I took one of my fingers and pushed it into her pussy. she moaned hard this time, her breathing had become harder. I began to finger fuck her and sucking her cilt. She began to hump my face."O fuck yeah, lick my pussy baby brother, fuck my pussy with your fingers." Soon I felt her tense up, she let out a scream and I knew that she had an orgasm. She pulled my face into her pussy as I licked up her pussy juices. When her orgasm had gone, I looked at her, my face covered with pussy. I kissed her. "Mmm I taste good" she said smiling. "Now your turn" she turned me over and was now on top of me. She kissed my chest and went down to my abs. She took my cock and rubbed it. She then took of my shorts revealing my 6inch cock. It was that long but it was thick. She looked at me and said that she hadn't seen such a thick cock before, but she then again had only slept with two guys, her two former boyfriends. She licked the head of my cock. This was a new experience for me. She fondled with my bolls. She took my cock slowly into her mouth. I felt her tong at the top of my cock. She looked me in the eyes as she started to rock her head up and down on my cock. I closed my eyes, not wanting this feeling to end. I came close and yelled at her. " I'm gonna..oohhh I'm gonna cuuummm.." She didn't seem to mind and took more of my cock in her mouth. I came again and again in her mouth. She tried to swallow all of it, and manedge it. She cleaned my cock. "Wow sis that was, I mean, wow. " Was all I could say. She came to my face and kissed me. I tasted my own cum which wasn't all that bad. "So brother, what's next?" We kissed a bit. " I don't know" I said, I knew what I wanted next. She kissed me and rubbed her pussy against my leg. My cock began hard again. I rolled her over and I was on top again. I kissed with passion. I truelly loved my sister, and she loved me. I took my guided my cock to her awaiting pussy. I slid the head in first. She was tight and my cock was thick. I pushed in slowly. She trusted her hips up and my cock disappeared into her pussy. I looked her in the eyes and told her I love her. She smiled and I began to hump her. She was moaning as I took my cock almost completely out and shoved it back in. My paced quickened and soon we were fucking like mad. I looked at her tits and kissed them. She moaned with pleasure. I felt my bolls hit against her ass. Her pussy squeezed my cock and I felt her tighten up. She screamed as her orgasm rolled over her body. I was not nearly there and wanted to cum so bad. I flipped her over her ass was now sticking up. I pushed my cock back in and began to doggy fuck her. She was moaning again and for the third time that night she had an orgasm. I didn't stop my pumping and kept going, pushing faster and harder. "Oh my god your cock is thick. Ooohhh I'm cumminnng.." She screamed as her forth orgasm came. This one sent me right over the edge and was close to cumming. "I'm fucking your pussy, oh fuck you feel so good" I pushed harder into her as I shot stream after stream of my sperm into her pussy. "Oohh yeaah" she yelled as she had another orgasm. She collapsed on the bed. I pulled out and then realized I just came in my own sister. I looked at her and she smiled and told me she was on the pill. I kissed her and she fell asleep in my arms. Next morning I awoke, seeing my 20year old sister in my arms. It was still early but I got up and went to take a shower. As I was showering I thought to myself this was going to be a great couple of weeks..
