Training Your Sister to be a Slut By Stormy Johnson Copyright 2014 (Mf)(M+f)(Preg)(Reluc)(Inc)(MM) He was attending his first semester college. It was about 50 minutes from his home town, close enough that he should be visiting his family on the weekends, but far enough that he could easily make up excuse to not. After his last final, he packed a bag and made the drive back home. He couldn't believe that he'd actually let the entire semester go by without returning home. His mom called constantly begging him to come for dinner, but he always had some sort of an excuse. His little sister had turned 13 while he was away. He knew she'd be pestering him constantly while he was back home for the Christmas break. He'd always been really annoyed by his little sister. She was almost 6 years younger and they had nothing in common. She was a nerd and he was a jock. He hadn't even though his frat brothers that he had a little sister because she was so embarrassing. As he parked outside the house, his mom ran outside so excited to see him. She hugged him for what seemed like forever and then immediately started in about how he hadn't come to visit at all and how much they had all missed him. Her main complaint had always been that he hadn't made it home for Savanah's birthday. He promised his mom that he would make it up to her. The gathered his bags and walked into the house. His dad was sitting in the living room watching football . He sat down and started discussing the upcoming bowl games with his dad. After about an hour, his mom called for everyone to come for dinner in the dining room. As he was standing to do as she asked, his little sister finally came out of her room to join them. She walked into the living room and he almost didn't even recognize her at first. So much had changed. She had grown her hair out, it had been this very short, boyish cut but now it was just past her shoulders. And her tits! She actually had tits. And she was showing them off too! Her low-cut top had as much cleavage pouring out of the top as he was used to seeing from the college girls on campus. Her hips and ass were working her low-rise jeans. Not to mention that she had to have grown a full inch. She walked by him without even looking at him. He couldn't believe it. She had always been so far up his ass that he couldn't stand it, and now she wasn't even saying hi. As she walked into the kitchen, he turned to follow her. He could see the top of her thong sticking up past her jeans. His cock grew hard almost instantly. "I'm sorry, excuse me, I need to use the restroom before dinner, I'll be right back". He rushed down the hall to the bathroom before anyone could notice the bulge in his pants. Once in the bathroom he took his cock out and stroked it furiously. He couldn't' believe he was so turned on by his own sister. He must be sick he was thinking. But he had to get this out, so he kept stroking his cock. He looked down and on the floor were a pair of panties and jeans. They were clearly hers. That just made him even harder. He reached down and picked up the panties. Bringing them to his face and inhaled. Oh, her pussy smelled so sweet! And at that moment he felt his cum start to shoot out of his cock, without even thinking he pulled the panties from his face and used them to catch his load. As soon as he was finished cumming, he looked down to see his sister's panties in his hand covered in his cum. FUCK! What had he done? He quickly tried to wipe up what he couldn't with toilet paper and flush that down the toilet and hid the panties under her jeans. Maybe when their mom came in to collect the laundry she wouldn't even notice. He then joined his family for dinner. He couldn't help but start at his little sister through-out the entire meal. His cock betraying him by getting stiff again half way through the meal under the table. After dinner, he was happy when Savanah excused herself to go back to her room. He was able to sit at the time for a while, talking to his parents while his erection subsided. That night, as he went to bed in his old bedroom, still exactly how he had left it when he left for college, all he could think about was the smell of his sister's panties. At 3am he laid in bed, stroking his cock thinking about it. He wanted to smell her again! He got up quietly while everyone else was sleeping; he snuck into the laundry room. It was just 3 feet from his bedroom door, so he didn't bother getting dressed. He'd be in and out, he thought. He found a couple cute pairs in there that smelled just as sweet as the pair he had found in the bathroom. He stood there, naked and erect, lost in the aroma of his little sister. Suddenly from behind him he heard "What are you doing?" He jumped and turned around to find Savanah staring at him. He grabbed a towel off the ironing board to cover up, but he knew she had seen everything. "Are those my panties in your hand?" He quickly tried to hide them behind his back. He didn't know what to say. He was just staring at her; she was wearing a tank top that just barely covered her newly formed breasts and a pair of panties. His erection grew even harder and he knew that even the towel wasn't hiding it anymore. "This is disgusting, I'm going to tell mom!" She turned to walk down to their parent's room, but without hesitation, he dropped the panties and the towel and reached out, one hand clasping over her mouth and the other around the front of her shoulders, pulling her backwards to him. He whispered into her ear "you aren't going to tell mom or dad anything!" and before he knew what he was doing, she was on the floor of the laundry room, the panties he had found earlier stuffed into her mouth and his hands pulling at the pair she had on. He couldn't believe how beautiful his little sister was; he pulled her tank top up exposing her tits with her puffy nipples, hard from the cool air, her pussy with just a small tuff of hair on it. He needed to smell it and taste it. With one hand holding her hands together, the other spread her legs open as he began licking her cunt. She was trying to fight him and trying to scream, but she couldn't. She tasted like honey. He lapped at her pussy, his cock raging the whole time. He could feel pre-cum dripping from his cock. He wanted to resist the urge. He knew he had already gone too far! But he couldn't. He had to fuck her!! He pulled up and onto of her, his mouth and tongue exploring her tits. Her hands town pinned down over her head, his cock pushing against her slit. She was trying desperately to beg him not to, but she couldn't say a word with her panties in her mouth. And before he could change his mind, he trusted with his hips inside her. She was so fucking tight! Her pussy was like a vice around his cock. He felt something resisting his cock from fully entering her. As he pushed harder and harder, tears started to stream out of her eyes and down her face. He closed his eyes so he wouldn't see the look on her face as he finally pushed past her hymen, feeling it pop on the head of his cock, she let out a muffled scream, but he just pounded inside her. It didn't take long, so she was lucky in that. Only 4 or 5 full strokes inside her and he was pumping his cum deep inside her. He could feel her sobbing under him even though he refused to look. As the last stream of cum left his cock, he leaned down next to her ear, "if you even think about telling mom and dad about this, I will make sure every boy at your school knows what a little slut you are and I will tell mom and dad that you came onto me and begged me for this. And with the way you were dressed today, so fucking slutty, I'm sure they'll all believe me over you." He pulled his cock out of her and got up, wrapped the towel around his waist and went back to bed. He could hear her getting up, whimpering as she put what little clothes she had been wearing back on and returned to her room. He slept like a baby that night. As he woke up the next day, he was terrified of his threat not being enough to keep her quiet. He got dressed and walked out into the living room. His sister was wearing sweat pants and a giant sweater on the couch. She didn't look up at all, as he sat down next to her. It was clear she hadn't said anything. Both of their parents were sitting at the kitchen table drinking their morning coffee, out of view from the couch. His mom called from the kitchen, "how did you sleep last night honey?" "oh mom, like a baby! Best night sleep I've had in months" and he placed his hand on his sisters thigh and began rubbing it. He leaned in and whispered to her "thank you!" That whole winter break went by with him waiting till everyone was sleep and then sneaking into his sister's bedroom and raping her. Each night he was able to last a little longer and she fought it a little less. On the 8th night, around the 30 minute mark of him pounding his cock into her, this time from behind, he felt something different. Her pussy started to get really really wet and began clenching down around his cock, her sobs turned to moans, and her body began to shake. Suddenly he felt a burst of warm fluid around his cock, shoot down onto his balls. She let out a load moan through the panties shoved in her mouth, so loud he worried their parents may have heard it. He had seen women squirt in porn, but never felt it happen. It was more than he could handle and he began to cum inside her. She continued to cum while he filled her up. They both collapsed onto the bed. He rolled over next to her and they laid there in silence. She removed the panties from her mouth , her body trembling. He had never stuck around after raping her before, but this was different. He could tell. After a minute he looked at her and said "have you ever had an orgasm before just now?" "no, never" "How did it feel?" "Amazing! Is that what you feel every time you cum while fucking me?" "it's not exactly the same, but essentially, yes" "well, then I guess I can't be mad at you anymore" "Would you like to have another one?" "oh god yes!! Toby, fuck me again" And he did. After that night, they fucked every chance they got. He taught her how to slide up and down on his cock while riding him. And she gladly sucked his cock to get him hard so he could fuck her again and again. She was insatiable, often still begging for me even after he was totally spent and all of his cum was deep inside her. He had turned his little sister in slut, a slut he couldn't completely handle on his own. He knew he had to keep her satisfied if he didn't want anyone finding out. He made a few calls to some fraternity brothers that he knew would fuck any pussy they could. It didn't take much convincing to get 4 of them to agree to help him with his horny "friend". He instructed his sister to tell them she was only a grade behind him, a senior this year and about to turn 18 (age of consent in the state was 16, but he didn't want to risk them balking at her being "too young" and was just a friend's little sister. He told his parents that he wanted to make up for missing her birthday by showing her around the campus, and that there was a big science fair going on that last weekend of their break. He promised that all of his frat brothers were away on break and that it would just be the two of them in the house that Saturday night and that he would have her back by 3pm Sunday, no later. They left early Saturday morning. The moment they got onto the highway, he undid his pants and took his cock out of his pants, she leaned over and started sucking him. She teased his cock for the entire drive, but not once letting him cum. As they pulled into the small college town, he put his cock away and made his way to campus. As he pulled into the frat's parking lot to find his buddies cars already there. They got out and grabbed their bags and headed inside. Once inside, he introduced Savanah to them. But before he could finish she was on her knees in front of him pulling his cock out and sucking it. The guys cheered and gathered around. They each took their cocks out and began stroking them around her. One of them helped get pants and panties off, while another unbuttoned her blouse and removed it and her bra. They all stripped down, as she took turns sucking each of their cocks. As she sucked the fifth cock, toby pulled her up and moved her over to the ping pong table, leaned her over it and began fucking her. "can you guys believe that just two weeks ago, she was a virgin?" the guys took turns at her pussy and mouth for hours that night, each of them dropping at least one load into each hole. Her pussy was dripping with cum. She couldn't get enough. She was in slut heaven. One of the guys looked at Toby and asked "have you fucked her ass yet?" "no, I haven't. but I've thought about it!" She perked up, this did not sound good to her. "I'm sorry, no, that's not happening". Toby went over and grabbed her by her hair and dragged her into the next room. "Excuse me, little slut, remember how much you didn't want me to fuck your pussy at first? And now you fucking beg me for it? If I decided that we're going to fuck your ass, then we're going to. And you're going to love it. Or all of this can stop and I can take you home. Got it?" "yes, Toby, I got it". As they walked back into the living room, he looked around and said "She's changed her mind. Who has lube?" One of the guys jumped up and ran up to his room and came right back with a big bottle of Astroglide. Toby bent his sister over and started fucking her pussy, as he lubed up a couple fingers and began working them into her ass, first just one, but then two and then three. All the while she's cumming over and over again on his cock. The other guys taking turns in her mouth. He pulled his cock out and easily slid it into her stretched asshole. Even with nothing in her cunt, she continued to orgasm from him fucking her tight asshole. She was cumming even harder than she had from begin fucked vaginally. She couldn't believe how good it felt. One by one they each took turns fucking her ass and dumping their hot cum inside her. As the night went on, they called and invited more of the frat brothers, some even from different fraternities, to come and join them. But the next morning, she has fucked 19 different guys with every single one of her holes. All of them bareback, filling her up. Around 7am, Toby called it, and told everyone that Savanah was done for the day. She needed to clean up and rest before he took her home. He showed her to the showers and helped her soap up. He leaned over and whispered, so no one else might here "I'm so proud of you little sis, I love you so much!" and kissed her sweetly. Back in his room, naked and cuddled on the bed, they couldn't help but to make love. Passionately, they kissed and caressed each other as they slowly and gently made eachother cum one last time. They knew it'd be the last time, at least for a while. This was different than the other times they had fucked. In the moment, when they both came, looking deeply into the other eyes, they knew it was more. They were in love with each other. Nothing was ever going to keep them apart. They fell asleep cuddled in eachother arms, when they woke up a few hours later, they kissed and got up to gather their things and be on their way back home. He kept at least one of his promises to his parents, and did have her home by 3pm on Sunday. He then said his good byes to his parents and snuck in one last kiss when no one was looking from his sister, before getting back in his car to turn to school for the new semester which started up in just a week. He had to back to buy books and get prepared. He thought about her all the time, and she him. He would call her every time to listen to her as he jerked off and she played with the toy he bought her. He went home much more often that next semester, which made his mother happy, if only she'd known what the cause of his visits were, she might not be so gleeful about them. As the semester came to an end, he was so excited to return home form summer break. He knew his sister had been fucking other guys, and was okay with that while he was away, but this summer it would just be the two of them again. When he went in to take has last final, his bags were already packed and in his car. The moment it was done, he headed straight home. As he pulled up, this time both his mother and his sister rushed out to greet him. He gave them both hugs but turned to his mom and told her he was exhausted and was just going to go lay down for a bit and needed to be left alone to rest. He went in, and went straight to his room and laid down. After a few minutes, his sister quietly entered the room and jumped onto the bed with him. They kissed and caressed eachother. "mom, thinks I'm in my room working on my final project for my 8th grade evaluation. She won't be bothering me, she's been harping on me to get it done for weeks." "you do have to finish that, you know! Trust me, you want to move on to 9th grade, where you'll be surrounded by juniors and seniors that you can fuck while I'm away. When is it due?" well, our finals are next week, so on Thursday when go in to take the final for that class, I have to turn it in" "oh, okay, we have a few days then, we'll get it done. I'll help you". And without saying another word, they stripped their clothes off. He noticed that her belly wasn't as flat as it had been. He stopped and stared at it. "Umm, Savanah, you look pregnant." She laughed "there's no way! I haven't ever had a period!! I know how this works. I have to have my period first. I've just been eating a lot and gained some wait. You still think I'm sexy right?" "Of course I do!", he said as he kissed her and pushed the thought to the back of his mind. they fucked with their parents in the living room watching a movie. Her pussy still felt so amazing; as good as it did even that first week. Post coital, the laid in bed, his hand on her stomach, not a through in his head. And then he felt it, a slight flutter under his hand. He paused and he concentrated and he felt it again. "Do you not feel that?" "yeah, it's just a bit of gas. Please don't be disgusted." "Savanah, that's not gas! That's a baby!" He did the math in his head, it had been about 4 ½ months since they had started fucking. He got dressed and went out to get a pregnancy test. When he got home, he made her take it immediately. He had been correct. She was, in fact, pregnant. She began to cry. "What are we going to do?" He sat there and thought about it for a while. "We can say that when you came to my school that you were raped, but you don't know by who. I'll take some blame for leaving you in the frat house alone that night while I went out for a few hours. And you can just say you never told anyone because you didn't want me to get in trouble. There's no telling whose kid this is, so many guys fucked you that night, but I'd love to think of it as mine, it's okay, I'll help you with it. We can do this together!" After a few days, she worked up the courage and told her parents the lie they had come up with. They were furious at Toby, but there was nothing that could be done about it now, and they were far less furious than if they had been told the truth! Her mom immediately set up a doctor's appointment. The doctor explained to Savanah that even though she hadn't had a period yet, if she had been ovulating for the first time that weekend, that she would have gotten pregnant and then never had one. It's extremely rare due to fact that most 13 year olds aren't sexually active but it does happen. They hadn't told the doctor she was raped because they didn't want to deal with the police getting involved. She just told him that the father was a boy at school, her own age. As the summer went on, her belly grew and soon there was no denying she was pregnant. Her little frame didn't hide much. Her and her brother continued their affair behind closed doors when everyone as sleeping or out. One night their parents went out to one of her mom's work party. They spent the entire evening making eachother cum. They didn't hear it when their parents pulled into the drive. Their dad stumbled into the house, having had a bit too much to drink at the open bar, while his wife pulled the car into the drive way and took a moment to feed their dogs. She was still outside when her husband stumbled into his daughters room to tell her they were home. As he opened the door he saw her bent over, with her brother on top of her fucking her ass. They didn't even notice and kept going as he stood there watching. He didn't know what to do! His cock stiffened in his pants. He slowly backed out of the door way and quietly shut the door. He then went back into the living room his mind racing about what he had just saw, he could hear them moaning. He knew if his wife came in and heard that all hell would break loose. He loudly slammed the front door shut and yelled out "hey, kids, we're home!". He could hear them jump up and hustle to put their clothes on. And they both ran out of her room, flustered . "hey dad! How was the party?" After a few minutes of making small talk, everyone went to bed. Their dad just couldn't stop thinking about what he saw, trying to figure out what he should do about it. Lying awake in bed, he finally decided. He quietly got up out of bed and walked down the hall, he opened his son's bedroom door and woke him up. "come with me, I need to talk to you and your sister". They walked over to his sister's bedroom and went in, waking her up. She was use to her brother coming in the middle of the night, so she was completely naked. As they turned on the light and she saw her father standing there too, she rushed to pull the covers over her. "there's no need for that honey, I saw everything this evening when we got home from the party. I walked back here and saw you two fucking". They both were completely silent. Finally she said "are you going to tell mom?" "well, honey, that depends. Is that your brother's baby in your belly?" "We think so, Dad." Said his son. "you THINK so?" "well, you see, I fucked other guys around the same time too. So we just don't know" "you both need to sit down and tell me exactly how this happened. And be honest! I need to know everything if you want me to keep your secret." They spent the next hour telling their dad exactly how it had happened. Starting with the rape in the laundry room through her fucking all of the college guys and up through that night when their dad caught them fucking in her bedroom. At first they thought he was going to be really upset and get angry. But as they told him what had happened, they noticed him getting aroused under his pajama pants. They looked at eachother and could tell they had both noticed it. "Dad, you know, over the last 6 and half months, Savanah has become very good at what she does. Especially sucking cock. You should let her show you." Savanah reach down and started untying the draw string her on her dad's pants. He didn't say a word and just let it happen. His pregnant, 13 year old daughter sucking his cock. He quickly shot his load into her mouth. "keep sucking, get me hard again" "You want to feel her sweet pussy, don't you dad?" "yes, son, I do, but first you have to punished for what you did to her. Take off your pants and get down on her hands and knees." "Dad! What? No! You can't be saying what I think you're saying" "boy! Do it or I'll go right now and tell your mother everything!!" He slowly got took his pants off and quietly got down on his hand and knees in the middle of his sister's bedroom floor. His father, who had a huge cock, positioned himself behind him. He rubbed his cock against his ass crack, pushing his head between his cheeks and against his asshole. "Dad, please, there has to be another way!" and his dad began to push the tip of his cock into his son's asshole. "DAD!! Please, at least use some lube! Savanah, please get him the lube in your dresser!" "Girl, you stay on the bed! Did he use any lube the first time he raped your virgin cunt?" "no dad, he didn't". and he thrusted his cock deep inside his son's asshole. His son tried to yell out but he pushed has face down into the carpet to muffle the screams. "how does it feel being raped, boy? Do you like it? I bet not. I bet Savanah didn't like it at first either. But trust me, just like her, you'll eventually learn to love it. It seemed like hours to Toby, but it was really only about 45 minutes, but still, his asshole was sore and red by the time his dad filled it up with his cum. After that night, their dad always joined them for their fun when he could; using any hole he wanted to. And their dad was right, eventually Toby learned to love having his ass fucked by his dad. Savanah loved watching it. It quickly became her favorite part of their play since she'd have Toby eat her pussy while their dad fucked his ass. Toby decided to take the next year off to help his sister out with the baby when it came. His mother tried to convince him that it was unnecessary and the she and their father could handle it, but their dad helped talk her into letting him take the time off.
