I won't see you after tomorrow and this is our last chance for you to fuck me!" said Sadie as she crawled up between my legs and rubbed my cock. "I don't know sis, I keep telling you that this is wrong. I mean really wrong and if Mom and Dad find out we are fucking each other Dad will kill me. Not only that but he'll kick me out and stop paying for school!" I said to her and she kept rubbing my cock in my jeans. She was no dummy. We had been fucking for months and she was not one to take no for an answer and she knew exactly how to make me say yes to her. "Oh come on big brother," she said as she stood up in front of me. Sadie is only 8-years-old but she is the sexiest girl I've ever seen. And I've seen plenty. She is thin but not overly skinny like I've seen. She has long brown hair and she learned very early how to style her own hair so she was not always wearing it the same way. She has big brown eyes and a petite little nose and sexy lips. She was dressed in a cute little white top that had one shoulder covered and the other side was a strappy thing that showed her bare shoulder and flawless skin. She was also wearing a pair of super skintight shorts that were very short. She turned and faced the television that I was no longer watching and she bent over in front of me and stuck her little bubble but up into the air and smiled at me. "Come on big brother, I'll let you fuck my ass again! I know you love sticking that big, hard cock in my ass. You know you do too!" She said as she put her hand on her ass and rubbed it up and down the crack of her ass it was an unbelievable sight. "Mmmmmmm come on, please? Don't make me beg for it!" I was doomed. I was about to fuck my sister for what had to have been the 50th time this summer. We were about to go back to school, she into the third grade and me back to college. I would be a sophomore. But wait a minute; I am getting way ahead of myself. This is a story about how I started fucking my little sister not how we said good-bye for the summer. It all happened when I came back from school. I'd been away at college. It was the first time we had been apart for such a long time. She is my half sister and she is just as hot as her mom, my step mother, who my dad snagged about 10 years ago. I had pretty much ignored my sis when I was away, she sent me some emails and I missed a few calls but I spoke to her at Christmas over the phone. She was always a little bratty and she usually got anything she wanted from my dad and that pissed me off. We can't afford me to fly home all of the time so I didn't see her all year. When my step mom picked me up at the airport when I came home for the summer she was with her. I almost fell over when I saw her for the first time. She had grown about 6 inches since I last saw her and she was dressed like a girl. Before I left for school, she always dressed in just shorts and tee shirts but now she looked like a girl and a hot one at that. She wore a pair of tight jeans with a snug fitting top that showed that she had no breasts to speak of; but her little girl nipples were pointy and bigger than I remembered. But it may have been that she never wore skintight clothes before and I just never noticed. "Oh Joey!" She cried when she saw me and she ran towards me and jumped into my arms. She hugged me so tight I was not sure what to say. She kissed me on the neck and on the cheeks covering me in little girl kisses. "I missed you big brother! I missed you so much!" "You have been all she could talk about this week. She was very excited you were coming home." My mom said. "I guess so!" I said as we started walking and she was still straddling me not wanting to let go. I carried her like that for a couple minutes but then our mom had her get down but she held my hand the entire way out of the airport and into the car where she begged me to sit in the back seat with her. I did and she hugged my arm all the way home gently stroking my arm and sighing occasionally. On the drive home Mom told me that her little girl started growing up this year. She made friends with some of the fifth graders in her school and even though they tried to dissuade her from befriending the older girls she became best friends with one of them and they were inseparable all year long. They noticed her dressing more grown up and found her wearing make up at the mall a couple times and have had to take some of the clothes that her older friends have been giving her. They give her clothes as they grow out of them and some have been inappropriate for a girl her age. When she said that I looked at Sadie and she just rolled her eyes and hugged me tighter. That first night home my dad came home and we had my favorite meal. Meatloaf! After 9 months of dorm food home cooking was what I wanted most. We ended up watching a movie in the family room and Sadie climbed up with me and I spooned her as we watched the film. She pushed cute little ass right next to my cock and she kept moving around until it got hard. I kept moving away, but every time I did she moved closer again and I knew she could tell there was something going on back there. One time she pushed back and I groaned liking the pressure she was applying. She turned and looked at me and smiled. Then pushed back again. My baby sister was rubbing her ass on my hard cock and loving it! I was sure she knew exactly what she was doing. After the movie we all went to our rooms and off to sleep and I jacked off thinking about my little sister and how sexy she was now even at such a young age. I knew this was going to be an interesting summer vacation with my family. Chapter 2 The next day was a weekday and Mom and Dad both had to work. This was one reason they asked me to come home; they got a free babysitter. I was kind of bummed before I got home but now it seemed like it would be a lot of fun. That day I decided I needed to see how much Sadie understood about wheat she was doing the night before and what she was really planning to do. We have a nice pool and Jacuzzi at the house and Said wanted to swim. She was still a little young to swim by herself and I don't think she would have wanted to anyways, so she asked me to go with her. I agreed and she ran off to get her swimsuit on and so did I. I have always been in pretty good shape and college track definitely was helping. So I put on my swim trunks and grabbed a couple towels and went out to the pool. I was just getting comfortable on the lounge chair when my little sister came outside and walked towards me. The swimsuit she had on was amazing. It was so small both on top and below. Her perfectly flat chest did not need that much coverage but her top was literally two tiny triangles that could not have been more than an inch and a half at it's widest. And her bottoms were also very small and went down so low in the front I thought it was a good thing she did not have any pussy hair or else it would have been showing. She walked to me and then turned around showing me the view of the bikini from the back and her ass was almost completely naked. It wasn't a thong but it was close. "How do you like my new bikini?" she said seeing the look on my face was likely enough of an answer! "Good, I love it too!" "Have Mom and Dad seen you in this bikini Sis?" "Oh no, this is one of those things they would call inappropriate. But what do you think big brother?" All she had to do was look down and see my cock was completely hard and excited as hell from just seeing her walk out to the pool. "It looks like you do like it Bro! You're all hard! Did I make you hard just from looking at me?" "Yeah Sis we need to talk. You need to stop teasing me because last night you could have given me a serious case of blue balls if I hadn't taken care of it when I went to bed." "Did you beat off last night Joey? Were you thinking of me when you did it?" she asked as she smiled at me and sat next to me on the lounge chair. "I'm not saying anything Sis. And seriously you need to stop it. I'm only a man and you cannot tease me like this." "Who said I'm just teasing you big brother?" "Oh yeah? Do you know what happens to girls who get their brother's all hot and bothered?" I asked. "Uh huh." She said quietly nodding her head. "What happens then?" She smiled down at me and giggled. "He gives it to her and fucks her silly!" "What the fuck sis! Where did you hear that?" I asked amazed that she was talking like that. "Mariah!" she said and she reached over and rubbed my stomach feeling all of my tight muscles there. "She's my best friend. She's the one Mom was talking about. She hates Mariah. She says she's a bad influence on me." "Oh yeah?" I said as she rubbed my abs looking at my body. She looked down at my cock that was fully erect and throbbing in my shorts. "What else did she tell you?" She has an older brother too. He's in high school though not college like you. So he still lives at home. She's so lucky!" She said still running her hand up and down my upper body rubbing my pecks and stomach still occasionally looking at my hard on. "Why is she so lucky?" "She sees her brother all the time. I only get to se you in the summertime now. I really miss you Joey." She said and she leaned down and hugged me. But when she did she moved her hand to my crotch and squeezed my cock feeling its size and hardness for the very first time. "I'm telling you, you better be carful Sis. Your gonna make me do something we both regret!" I said moving her hands off my body. "Can I suck it?" she said batting her eyes at me and licking her lips slightly. "Holy shit! Are you fucking serious? Have you ever sucked anyone's cock before?" She nodded and gave me a lewd look. "Uh huh! I sucked off Mariah's brother Marcus! But his cock didn't look as big as yours. You look like you have a big one big brother!" I was amazed. My 8-year-old sister was asking if she could suck my cock. How could I say no? She already had me very turned on and all I could do was concede. "Sure Sis, you can suck my cock. But you cannot tell anyone about this. Not even Mariah and mostly not mom or dad. Okay?" She nodded quickly and reached out and grabbed my cock. "Can I see it?" I stood up in front of her as she stayed seated on the lounge chair and she waited anxiously as I untied the sting on my swim suit and pulled it out of the inside of my shorts. Then I moved closer to her and she dropped a towel that was on the chair in front of her right next to my feet and she dropped to her knees and pulled my trunks down seeing my cock bob up and down in front of her. She smiled and said, "Wow!" as she reached out and touched it for the first time. "It's so big!" I'm not here to say I have a big dick, but it's almost 8 inches and pretty wide. None of my girlfriends have ever complained and most of them say the same thing my sister just said so I guess I'm better than average. She touched it and I moaned as she started rubbing it in her hands. "Ohhh shit!" I said and she moved closer and put it in her mouth. I could not believe how good it felt. It'd been a couple months since I last had sex so I was pretty horny. She started bobbing up and down on my rod and I was sure that she was telling the truth and in fact this was not the first time she sucked cock. That made me feel better. I would hat to take advantage of such a young girl but she seemed like she knew exactly what she was doing and liked it. I felt less guilty like that I guess. She was looking at me as she sucked me never talking her eyes off me as she went deeper and deeper. Pretty soon she had me as deep as she could without gagging. She hit her throat a couple times and gagged. But she never stopped and she just sucked harder and harder as she was obviously trying to make me cum. I was really enjoying the blowjob and I was sure to explode soon. "You know what's going to happen soon right?" I said. She looked up at me and smiled and said, "Are you going to cum in my mouth brother?" and she went right back and sucked my cock harder and faster than before. "Uh huh!" I grunted and got ready to cum. When I came I pulled her face deeper onto my cock and spewed load after load deep into her hot sucking mouth. She swallowed it like a pro and never missed a drop. "Uhhhhhhh yeah Sadie, swallow it all!" I groaned as I filled her up with my incestuous seed. The site of her sucking my cock in that tiny bikini was one I will not soon forget. She pulled my cock out and looked up at me smiling and said, "Wow Joey that was a lot! Do you always cum that much?" "Gee sis I don't know. But I haven't been laid in a couple months so that likely had some saving up." "Yah but you jacked off last night! That's a lot! And it was yummy! You can ask me to suck your dick anytime you want!" My cock started getting hard again hearing her say that. I sat down on the lounger again and stayed naked. Mom and Dad had no intention of being home today so I figured it was fine. "What else have you done with your new BFF and her brother?" I asked. She sat next to me and smiled with her eyes all big and sexy. "Really? You want to know?" "Yes." I said. I wanted to know what she already did. "Maria taught me how to kiss. That's how it all started. I was over on a sleepover. Mom and Dad really hated that one. I only got to do it the one time. She talked about how she and her boyfriend kissed all the time and I was curious so we started kissing each other and it was so cool. That was when her big brother walked in on us. He liked little girls and as it turned out it was her brother that was her boyfriend after all. He wanted to watch us kiss then when he got a hard on he wanted Mariah to suck him off so he showed me all bout that. I loved it and he came in my mouth just like you did. But yours is so much better. I smiled at her and asked, "So was that it?" "That was all I did with him. But Mariah and I still do a lot with each other. She can come over here so sleep over and when we do we play with each other and we lick each other's pussy and finger each other too!" "No shit! And you are 8 and she is 10?" "Yeah, it's not like it was when you were a kid. We know a lot more about sex way before you did I bet." She said. "Yeah I was playing with race cars and stuff like that when I was 8." She giggled and looked back at my cock and squeezed.' You're still hard does that mean you want another blowjob?" "Maybe Sis! Would you give me another one if I asked you to right now?" "Sure!" she said and stroked my cock a couple times. "Why don't we go back in the house and I'll eat your pussy! Have you ever cum yet?" "Fuck yeah I do!" she said shocking me with her language. Mariah makes me cum good. She's the best pussy eater ever!" "We'll see, I think I'm pretty good too!" "Lets go!" she said pulling me up off the chair and guiding me into the house. I closed the patio door and we went into the family room and I stood her in front of the sofa and got on my knees in front of her to get her undressed. I pulled the string behind her neck and her top fell down exposing her tiny pink nipples. They were perfect and I just wanted to suck them. But I removed the top by pulling on the string behind her back. It fell to the floor and I focused on her bottoms. These I just pulled down over her slender hips and it joined its partner on the floor. I leaned down and took her right nipple in my mouth and sucked on it making her moan. She liked me sucking her tiny undeveloped tits. I moved to the other one and gave it the same attention. She put her hand on the back of my head and ran it through my hair. She really dug it. I lifted her up onto the sofa cushion and I positioned her tiny pink pussy on the edge and pushed her legs back to her chest. I moved onto my position between her young legs and I started licking. Her pussy was big and bulbous. Her lips were large and puffy and when I pulled them apart with my fingers I found her tiny clitoris and her inner lips were very bright pink and already moist. She tasted better than she looked too and her pussy looked amazing. I sliced her pussy lips with my long tongue and was running it up and down her crevice getting it inside as much as possible. She groaned as I licked her cunt and soon she had her eyes closed and was holding my head in both hands as I licked her pre-teen pussy. It was when I focused on her tiny clit that she made the guttural groan as I closed my lips around it and sucked gently. "Oh fuck that feels good big brother! Suck it!" she said as she started grinding her pussy on my mouth and soon she was getting closer and closer to an orgasm. She clutched my head between her legs and she came. "Ahhhhhh yes, yes, yessssss!" she cried as she came on my tongue. I almost could not breath but I managed somehow and finished her off making her cum a second time. My cock was very hard and now drooling pre cum as I straightened up and looked into my sister's dreamy just came eyes. "So do you want me to fuck you Sis?" "Uh huh" she grunted and I moved closer putting my cock against her tiny pink pussy and rubbed the head between her lips. She closed her eyes loving the look and feel of my cock between her ready lips and that urged me to push. I gently pushed into her tiny little pussy and she gasped as I entered her. "Ohhhhh yes!" she groaned as I made it inside her easier than I thought I should have been able to. Once the head was in her she opened her eyes and looked at me and said, "Now! Fuck me Joey!" I did not hesitate and I pushed easily inside her and there was no cherry protecting her womb. I was halfway inside her and I tightened my grip on her and pushed completely inside her with a single push. She grunted as I entered her completely but there was no way my sister was cherry. I got kind of pissed off that she lied but then I realized I was fucking my 8-year-old kid sister in my parent's living room and I got over it quickly. I started fucking her faster giving her all I had then pulling it out of her until only the head remained then back down on my cock. She was really enjoying it and I fucked her at a steady pace. She took all of my meat and was fucking me back shoving her thin hips up at me as I fucked her deeply. She wanted me to cum inside her or to give her another load in her mouth to swallow. But I had a different idea. I fucked her and when I felt cum churning in my balls I moved closer to the orgasm. When I knew I was going to cum I pulled out of her tight pussy and jacked off and came all over her stomach and chest. It was another huge load and there was cum everywhere. She spread it all over herself. All over her flat chest and tiny pink nipples. All over her freshly fucked pussy making it glisten with sheen of cum. All over her tight stomach and then she scooped some of it that collected in her belly button and slipped it into her mouth. She did love the taste of it that was for sure. She smiled sexily at me and winked after she put it in her mouth.
