The next weekend, my parents had to go out of town for my dad's work. he was a DJ at the time, and they were doing a special on a band playing at a casino in las vegas. This meant that my sister and i were to be trusted to be alone in the house for an entire weekend, no adult supervision. as you can imagine, this was not my parents best decision! The weekend fuckfest began that friday night after my parents left. as soon as we had said our goodbyes and closed the door behind our parents, we sprinted into my sister's room and began undressing. we had both been craving eachother ever since the weekend before, and although the entire week we never said anything about it to eachother, we would share the occasional glance at eachother. There we were, completely naked in my sister's room, wanting eachother's bodies more than anything in the world. i lunged for my sister, falling onto the bed on top of her, and we began kissing furiously. she reached down and grabbed my cock guiding it into her pussy hole. i began pounding her pussy furiously, this was no time to fool around. we had both been waiting for this moment, and we both wanted it so bad we couldn't control ourselves. i thrusted into her until i came harder than ever. that night we fell asleep next to eachother in my sister's bed. it was the first time we ever actually truly slept together. I woke up to my sister moving around as she too woke up. we rolled over and stared at eachother for a couple minutes, then exchanged a long kiss. she reached down and grabbed onto my cock, and began massaging it, staring me in the eyes. i returned the favor, and began to play with her clit. i was suprised to find that she was already getting a little wet, and it was very easy to slide a couple fingers in. we laid there for a minute, playing with eachother until i came and her hand got covered in my cum. she decided she wanted take a quick shower while i made us breakfast. We had a nice breakfast which was fairly uneventful. we made small talk about what we wanted to do that day. She said she was going to have a couple of her girl friends over, and i decided i would go to a friend's house for a couple hours. we both went about our day. when i came home, my sister's friends were still there with her. she had two of her best friends there, Ashley and Nicole we'll call them. as i walked in the front door, all three girls immediately began giggling and whispering to eachother. I was immediately terrified. what had she told them? did they know what my sister and i had done the night before? were they disgusted by me? would they tell everyone at school? i asked what they were talking about and they said "a boy from school" and i ignored it. my sister's friends left a couple hours later, and i decided i would ask my sister if she had told them. we had never really talked about it, i assumed we both knew no one could ever know what we had done. but now i thought about it, maybe she didn't think so? I asked her, "did you tell ashley and nicole what we did?" "No! of course not! they would freak out!" she responded. I was still skeptical. i guess she could see it in my face, because she got up and moved towards me, took my hands in hers, and leaned in and kissed me. she said "look, what we do is only for us to ever know. i know what people would think about it, and it's none of their business. our little secret!" I knew she meant it. "and what is THIS?" she added, grabbing my cock, which i had failed to notice had become instantly hard the moment she kissed me. "oh.. that's just... um.." i didn't have to finish. we were in the living room, and there were two couches and a chair, as well as our t.v. and fireplace. she dropped onto her knees, right there in the middle of the living room, the blinds open, the sunlight shinging in, pulled my cock out of my pants, and began sucking then and there. I stood there in shock as my sister sucked on my cock, not sure how i felt about it. she was bobbing up and down, and twirling her tongue around the head of my cock. i could hardly stay standing. i told her "wait, let me sit down..." and she pulled her head off of my cock to smile and say "sure." i walked over to the chair and sat down, my pants unzipped and my cock hanging out. my sister followed me to the chair, got on her knees and picked up where she left off. she sucked my cock until i shot a load down her throat that made her cough for air. she swallowed the whole thing. she stood up, and udid my pants the rest of the way, pulling them off and throwing them aside. she was wearing a fuck me skirt that was so small you could see her panties when she bent over. she slid her thong off from under her skirt, turned her ass towards me, and sat down right on my cock, falling back against me. she began moving up and down on my cock, i moved my hands to her shirt, and pulled it down to expose her tits. i began playing with her nipples and rubbing her tits as she rode my cock up and down. she began moaning as she began riding faster and faster. she got up off of me before i came, and layed down on the couch, face up, spreading her legs and eyeing my cock. i walked over to the couch, placed myself between her legs, lifted her legs onto my shoulder, and pressed my cockhead into her pussy hole. as i began a medium paced rhythm of fucking her, she began moaning more and more. she was playing with her tits with one hand and rubbing her clit with the other. i pumped faster and faster and her moans grew more intense, longer and deeper with each thrust into my sisters tight wet pussy. she said between moans "i want your cum on my tits!!" i rammed her harder until i was close enough to cumming, then i pulled out, and began rubbing my cock until i came and sprayed my load all over her tits. she continued rubbing her clit as i let out my load. we both got up from the couch, and my sister said she was going to go wash off in the shower, and that i should join her. So we made our way into the bathroom, and turned on the shower. we showered together, washing eachother's naked bodies, kissing eachother, and rubbing eachother. when we were both clean, we got out of the shower and dried off. as we were standing in the bathroom, my sister suprised me by saying the hottest thing any female has ever said to me in my life, even since. her exact words were "next time, let's fuck on mom and dad's bed..." i was stunned. this had been a fantasy of mine for years. the idea of desecrating the place my parents slept... what a turn on! "sure! let's do it!" i told her. she giggled and walked out of the bathroom. i was unsure when she wanted to do it, but i knew i was spent. i couldn't cum again that night if my life depended on it, so i decided that if she hinted at doing it tonight, i would tell her let's wait. she must have been tired too, because we ate dinner, and went to bed without any more action that night. although, we did sleep naked together again, this time in my room. the next day we were both excited to fuck in my parents room. it was the first thing we talked about as soon as we woke up. "so are you excited to fuck in mom and dad's bed?" she asked me. "i can hardly wait. should we head that way?" and she nodded in agreement. we both got up at the same time, and sprinted through the house, buck naked into my parents room. she got there first, and she jumped onto their bed, ass in the air, moaning and saying my name. "mmmm i want you so bad," i could hardly control myself. i got behind her, and was about to put my cock in her pussy when she said "wait! put it in the other hole." i had never done anal before, but her asshole looked perfect. so tight, so beautiful. i said "are you sure?" and she simply moaned. so i took my dick in my hand and pressed it against her waiting asshole. i couldn't get it in though, it was too dry and rough. "you have to spit on it first" she said, giggling. "oh..." i mumbled. i spat on her cornhole, and tried again, pressing the head of my cock into her asshole. this time, i managed to get it in, and as i pressed the head of my cock into her ass, she moaned like i had never heard her moan before. it was mostly pleasure with a small amount of pain, and a lot of desire. i pressed more, and my cock went deeper into her asshole until i was all the way in. i started to pull back slowly until i was about half way out, and then pushed in quick and hard. she gasped for air. i started pumping my sisters asshole at a slow pace, pulling out a little deeper, and pressing in a little faster with each pump, as her ass loosened and tightened around my cock. i pumped her faster and harder, picking up speed until i was thrusting as fast as i could. her moans were almost screams of pleasure by now, and she had began to play with her clit. i was so turned on, it didn't take long for me to fill my sister's asshole full of cum, and we both collapsed on my parents bed. we layed next to eachother for a moment, while we caught our breath. I decided to go get us both a drink, while she went and washed her asshole out in the bathroom. i came back and handed her a glass of water, which she gulped down like it was my cum. we were both hungry so we went to the kitchen for breakfast. we ate our breakfast in the nude, smiling and eyeballing eachother's no-longer-private parts. she grabbed my cock under the table and started rubbing on it. we finished our breakfast, and with a raging boner, i cleared the table. then i turned to my sister and said "just look what you've done! what are you gonna do about this...?" she responded with "here, let me show you..." and she pushed me onto the breakfast table, and climbed on top of me. she placed a hand on my cock and guided it into her pussy, taking my entire cock into her. i was lying flat on the kitchen table, and she was straddling me. she moved her body up and down my cock, playing with her clit as she began thrusting. she moved up and down, back and forth and wiggled her hips in a circular motion that drove me crazy. i had my hands on her hips, and my eyes were closed in pleasure. we moaned in unison as she bobbed up and down on my member faster and faster. "i want you to cum on my face" she said "i want your cume all over my face" and i moaned in agreement. she slowly rose off of my cock, and got off the table. i sat up and before i could get up, she was on her knees in front of my cock "let me know when you're about to cum" she said as she placed her lips around my cock, and began teasing the head of my dick with her tongue. she sucked on my cock, running her lips up and down my shaft for all of about 30 seconds before i said "here it comes!!!" she pulled my cock out of her mouth, and started jacking me off as fast as she could until i came. i shot the load all over her face, it hit her in the nose and eyes first, and then on the lips and cheeks, and one last splurge on her forehead. the pearly white cum on her face was the hottest thing i had ever seen. we shared one more shower together, soaping eachother up and making out, caressing eachother's bodies, but that was the last thing we had time for. a few hours after our last shower together, our parents arrived home. this weekend was the best weekend i have had in my life, and i wish i could stay in that weekend for the rest of my life, fucking my sister in our house, alone together, 13 and 14 years old, for all eternity. truely heaven.
