My Sister Jo

[Stud Muffin]

I want to tell you about my sister. She has always been a bit of a tease and has flirted with me quite a bit lately. Her name is Jo and she is three years younger than me. She is 19 years old with blond with shoulder length hair and she has a lovely curvy figure and big breast. One day last fall she looked fantastic, I was in my bedroom and Jo called me into her room to help her with a poster she was putting up. I put it up for her and we both sat down on her bed to look at it.
It looked good and we began chatting. I had always got on well with Jo but i never thought of her in a sexual way before until recently when she started flirting with me. We spoke for a while and i thought she looked sexy, she was wearing a white crop top shirt without a bra and she had black jogging bottoms on which made her butt look big and round. As we sat next to each other she leaned across me to get her diary out of her nightstand. Her tits rubbed against my arm and I got an instant hard on. I think she noticed that i was aroused as i got straight up and left the room. I went downstairs and she followed me, I looked behind me and when she ran down I could see her tits bouncing around.....nice!

The next might our parents had gone out for the evening leaving Jo and I alone. We were watching a dvd downstairs and Jo was lying on her belly on the sofa. I sat on the arm chair watching her. She had noticed I was watching and she began moving her butt. She had a blue short dress on and I could see her white panties as she wriggled her juicy ass. I watched her clenching her ass cheeks together as she thrusted up and down. It looked like she was fucking an imaginary person and I wished I was underneath her. My cock was hard and i tried to hide it because I was only wearing a shorts. She looked at me and I thought she was giving me a sign to go over to her by the way she was moving her butt. I went over to the sofa and without thinking about what was happening i layed down on top of her. She was still bucking her hips and my hard cock pressed against her ass cheeks. We stayed like that for a few minutes and as I lifted myself up she turned to face me. Without saying a word she parted her legs and i noticed her white pretty panties were wet. I layed back ontop of her and she licked her hips. I could feel my cock rubbing her wet cunt through her panties.

I felt like i was going to cum in my shorts as we simulated sex on the sofa. She put her arms around my ass and grabbed me and began to grind her hips against my cock. I was going to cum and I started to pump her. My cock was rubbing her wet panties through my shorts then I couldn't hold back any longer and I shot my load inside my shorts. I then layed there for a moment as she continued to buck her hips against me, then I got off her and went to change my shorts. I changed into some sweatpants and went back downstairs and sat on the armchair. Jo was sitting on the sofa with her dress just above her thigh and I could see her hairy damp patch through her panties. Damn it looked nice! She looked at me and still not saying a word she went upstairs. I don't think she really realized what had happened, she never meant for it to happen. She was just turned on like me and probably thinking we shouldn't have let the flirting go any further.

I waited for a while then I went upstairs to see if she was alright. I opened her bedroom door and she was lying on the bed. I noticed her legs slightly apart and she still had her panties on. She told me to sit down and I sat on the end of her bed. She then started to move her hands down to her panties and she began to rub her beautiful pussy I knew she wanted more so I put my hands on her pussy and began to rub her cunt with my finger. She put her hands behind her back and she let me continue rubbing her cunt through her panties. I moved my head towards her cunt and put my tongue there. I started to suck her pussy through her panties at first, then i pulled them to one side and began to lick her soaking cunt. She sighed as I fingered her and tongued her. She tasted so good and I thought about fucking her so I moved my head up and lifted her dress up and then began kissing her belly. I worked my mouth up towards her big tits and she helped me by lifting her dress up over them. I sucked and kissed her hard nipples for a while. Her tits were big and they were very bouncy and I rubbed them as I kissed them all over. I began to kiss her on the neck and then she reached down and put her hand down my sweatpants.

She took my hard cock in her hand and began to stroke it slowly at first, then she began to get faster and faster. I pumped her hand as she held me tight and the pre-cum dripped over her hand. She then asked if Ii could take off my sweatpants and I did. I took of my shirt and she began to kiss my chest. I layed on my back and she worked her kisses down towards my belly and then she began to nibble on my thigh. I put my hands on her head and guided her to my cock and she put her warm lips around it.

She gave me a really great blowjob just like an pro. She sucked my balls then flicked her tongue over the tip of my wet cock. I fucked her sweet mouth for about ten minutes or so then she pulled my cock out and told me she wanted it up her pussy. I told her to get on top of me. She then lowered her self onto my cock and I could feel my hard cock slipping slowly up her wet hairy pussy. I thrusted my hips and she bounced up and down on my cock. She was panting hard and out of breath as she jumped up and down on me. She began to make really loud noises and I thought she was going to wake up the neighbors. I then grabbed her hips to try and control her movements. Her tits bounced up and down and I started to kiss them. We continued to fuck in that position for a while and I then told her to get on all fours. She did, and she looked good as she stuck her big round ass up in the air. I grabbed my cock and rubbed her asshole with the head of my cock, then I moved it down and entered her wet hairy pussy. I fucked her hard slamming my big balls against her.

She was panting really hard making noisy sighs every time a pumped her pussy. I am not sure if she reached an orgasm or not but she screamed really loud and I pulled out my cock and gave it a couple of pumps with my hand a shot my cum all over her back. I rubbed some of my cum over her asshole and used my finger to rub it into her tight butthole. She said she liked her asshole fingered and I continued to finger it for a while. I loved the way she looked with her ass sticking up, I kissed it all over and playfully bit her ass cheeks. She began laughing and we layed on the bed together and began to talk like we had done nothing wrong.
We were both completely naked as we layed there in bed, I turned to look at her and she looked back at me when and I noticed how lovely her pretty face really was. I moved my lips towards her and we began to kiss her passionately. My tongue darted in and out of her mouth as we kissed like we were lovers. At that moment I felt like I was with my lover and not my sister.
But then we heard someone at the door, it was our parents so I rushed back into my room and acted like nothing had happen for the rest of the night.

The next morning Jo had said nothing to me about last night and so we just carried on like normal brother and sister like nothing happened.
A week had past and my parents were going shopping and Jo who world normally go with them told my parents she didn't want to go this time so they went without her. After they left Jo looked at me and blew me a kiss. I blew one back as she went up the stairs. I followed her and went into her room, she sat on the bed and I sat beside her. She then lifted up her little yellow shirt to show me her large white tits. Right away I began to rub and kiss them as she layed on the bed and then told me to take her again. I jumped at the chance and began to kiss her breasts her neck and her lips. Once again we fucked until our parents came back, and now whenever we get the chance we have sex with each other. To ease our guilty feelings when we finish having sex we don't say anything to each other or talk about what happened. We just have our fun then carry on as if nothing has ever happened.

We went on vacation to Hawaii the next summer with our parents and we had a lot of chances to be alone together and it was really good!
But that's another story.
