Date: Mon, 26 Jun 2017 13:46:45 -0700 From: Jojo Starr Subject: Mia & Brittni MIA & BRITTNI (ff, mast, inc, voy) Mia had been undergoing some confusing changes lately. Outwardly, she was a normal 14 year-old girl with pretty brown eyes and soft, light brown hair that came down to her shoulder blades. But inwardly, she had been dealing with some intensely conflicting emotions. She had been close with her big sister Brittni for years - had watched her grow up and mature into a young woman. Brittni was seventeen now and had become quite beautiful. She was a little taller than Mia, with big green eyes, a soft sweet face with shiny red lips, and long brown hair, a bit darker than Mia's. Her beauty was not lost on Mia. In fact, it was almost all Mia could think about when she looked at her, and even when she wasn't looking at her. Mia was a bit bothered and a bit embarrassed by her feelings toward her sister. Whenever she saw Brittni in a cute outfit, short shorts, a tight t-shirt, or - God forbid - a bathing suit, she felt her stomach swirl, her heart pound, and her knees weaken. She knew she shouldn't be feeling this way about another girl, let alone her own sister. But she couldn't help it. No matter how wrong she told herself it was, the feelings never went away. In fact, they actually seemed to get stronger. It also didn't help that Brittni was on the high school dance team and performed at all the rallies and school events. Mia, being a freshman, would sit in the bleachers along with all her other classmates and watch as the dance team performed, her eyes focused on her big sister as she moved, swayed, and danced to the rhythm in impossibly sexy ways. It drove Mia wild. She could always feel her temperature rise and her heart pound as she watched her sexy sister move, and hated the fact that she had to hide it from her friends, who were often sitting right next to her. One Monday after school, Mia was home by herself trying to do her homework. Her parents wouldn't be home for another few hours, and neither would Brittni, who was at dance practice. As she stared at her math book, she couldn't stop thinking about the dance Brittni had given at the school rally that morning. The entire dance team had been dressed in tight black spandex pants and a matching spandex tank top. The form and shape of each girl's body was on display, but Brittni outshone them all, Mia thought. Every curve on her body was absolutely perfect and proportionate, and she moved her hips and torso better than any girl out there. Mia slapped her pencil down on the book in frustration. There was no way she was going to be able to get any homework done. She sighed, turning her head toward the hallway, and suddenly she got an idea. Brittni's room was right down the hall. Her stomach filled with butterflies as she thought about it. Should she do it? Go into her sister's room? Snoop around? She wrestled with the thought for less than two minutes before making up her mind and rising to her feet. Slowly, she walked down the hallway to her sister's room, approaching the closed door. Slowly, she grabbed the handle, turned, and the door pushed open. As she peered into her sister's room, she saw that Brittni was neat and organized with her books, CDs, and school papers, but less so when it came to her clothes. Various articles of clothing lay strewn about the floor, bed, and chair. Gently, Mia tip-toed her way in, scanning the room with her eyes. Brittni's essence was everywhere, and Mia drank it in. Her eyes stopped at Brittni's bed, noticing the indentation on her pillow where her head had been. Mia's heart began to pound as she thought about her sister sleeping there. Almost on instinct, she moved toward the bed and paused as she stood over it. How close did she want to get? Biting her lip as her heart pounded, she leaned forward on her hands and slowly began to crawl onto her sister's bed on her hands and knees. Slowly, she laid herself down on her stomach, her head just over her sister's pillow. Heart pounding, she lowered her face and pressed her nose to her sister's pillow, inhaling deeply. The sweet scent of Brittni's hair and shampoo filled her nostrils, making her light-headed. Mia inhaled over and over, feeling her heart beat faster and her stomach swirl stronger. The sensations were so intoxicating, she involuntarily began to press her hips down hard against her sister's mattress. Then, suddenly realizing what she was doing, she lifted her head up with a start. Her heart pounded as she looked down at her sister's pillow, very conscious of the swimming sensations in the pit of her stomach. When her hips had pressed into the mattress, it somehow seemed to pacify her, giving her what felt like temporary relief from the throbbing ache of desire all over her body. A thought occurred to her, and after a slight pause of uncertainty which she quickly pushed aside, she grabbed her sister's pillow with one hand, rolled her hips to the side, and stuffed the pillow underneath them. When Mia rolled her hips back down, a heavy sigh escaped her lips, followed by an unexpected moan. The sensation seemed to calm her ache almost immediately. At least until it came back, which was about three and a half seconds later. She pressed her hips against the pillow again, groaning with more relief. As her heart continued to pound, she began rolling her hips from side to side on the pillow, her eyes fluttering at the wonderful sensations it caused. Her consciousness temporarily coming back to her, she quickly rolled her hips to the side again, lifted one leg slightly, and with her hand stuffed a bunch of the pillow between her legs before settling back down. Groaning even louder this time, she began to lose her inhibition and pushed her hips even harder against the pillow. The sensations were incredible. Searching around, she found a nearby tank top of Brittni's on the bed. She grabbed it and pressed it to her face, inhaling deeply. Sweet Brittni fragrance filled her nostrils. With her free hand, she clutched the bedsheets into a fist and began pumping her hips against the pillow, her heart rate skyrocketing. The sensations never seemed to be enough to quell the burning ache between her legs and Mia felt overtaken by the intensity of her urges. Without thinking, she thrust over and over, pummeling the pillow with her hips as Brittni's bed began squeaking heavily with the rocking motion she was creating. Mia thought of her sister laying in this very bed, right where she was this very moment, her beautiful, soft, tender body curving in all the right places. "MMMPH!" Mia gasped unexpectedly, her body seizing with a powerful sensation that sent heavy currents of unbelievably wonderful energy throughout her young body. When it was over, Mia lay limp and panting, her sister's pillow still stuffed between her legs. As she slowly came to, the realization of what she'd done began to dawn on her. She was in her sister's room, on her bed, and had just humped her pillow. What kind of pervert was she? And what was that sensation? With a start, she realized it was an orgasm. Her first orgasm! Against her own sister's pillow! She quickly began to feel disgust rise in her throat. Frantically, she pulled the pillow from between her legs and placed it back where it was, careful to create the same indent in a head shape that was there before she arrived. She slowly got up off her sister's bed, crept out of her room, and closed the door. As she got back to her own room, Mia felt her head begin to spin. What had she done? It was so perverse! But at the same time, her heart was still pounding from it. Moreover, she had felt something between her legs as she walked - a slick sensation. She unbuttoned her shorts and pulled back the waistband of her panties to look at herself. She was shocked to see a dark wet spot in the crotch of her panties, along with a shiny wet substance covering her puffy young vagina lips. She slid a hand down to feel it. Her fingers came away warm and slick. As she rolled the stuff between her fingers, she noticed it had a slimy consistency. Tentatively, she held her fingers to her nose. It didn't have much of a smell, other than her normal odor, which was quite pronounced. She wiped the stuff on her shorts and buttoned herself back up. Trying to shake it all off, she sat back down in front of her math book, trying to concentrate. But it didn't work. The sensations she'd just had in her sister's room were all she could think about. **************************************** Mia's thoughts and urges about what she'd done stayed with her the rest of that day and on into the next. She was ashamed of what she'd done, but at the same time it was so incredibly thrilling and intoxicating, creating an intense desire to do it again. But she couldn't do it again, could she? It was wrong, wasn't it? All day at school the next day, Mia thought about wanting to do it again, and the more she thought about it, the more she wanted to do it. But her heart sank when she remembered that it was a Tuesday, and Brittni would be home after school. She only had dance practice on Mondays, Wednesdays, and Fridays. Mia felt overwhelmed with frustration. That night she could barely sleep as thoughts of what she'd done in her sister's room flooded her head. When Mia woke up on Wednesday, she immediately felt refreshed and renewed. Brittni would be at dance practice today! Her heart pounded with excitement, and it was all she could think of throughout the day. That afternoon when she got home, she was nearly trembling with excitement. She checked the house to make sure no one was home, dropped off her bags, and immediately went to Brittni's bedroom. Again, the door was closed, but it wasn't locked, and Mia crept inside. Just looking around her sister's room, and especially seeing her bed - and pillow! - got Mia incredibly excited. She felt her heart pound as she once again approached her sister's bed. She knew exactly what she wanted to do. Practically trembling with anticipation, she unbuttoned her shorts, and slid them down to her ankles. Then she climbed onto her sister's bed on her hands and knees, reached out and grabbed her sister's pillow, positioned it beneath herself, and lowered her panty-clad hips down on top of it. Mia sighed as she felt her sister's pillow press into her. She rolled her hips again and stuffed a big bunch between her legs before settling back down. Her eyelids fluttered as her eyes rolled back into her head. The pillow felt so much better against her panties than it had against her shorts. She squeezed her legs together tight, compressing the pillow against her crotch, and groaned. Almost immediately, she began pumping her hips. As she pumped, rocking the bed back and forth, she scanned the sheets around her. Spying her sister's night shirt, her heart leapt with excitement and she reached out to grab it, pressing it tight to her face. It had a much stronger Brittni fragrance than the tank top she had found the other day and drove Mia wild. She pumped her hips harder and tighter into the pillow, breathing in her sister's fragrance eagerly through her nostrils. The feelings came on stronger and faster than before, and after only two or three minutes of hard, tight pumping, she gasped as she felt her body seize up. Mia, picturing her beautiful sister in bed next to her, thrust her hips tight into the pillow, grinding them around as she squealed in orgasm, her sister's shirt mashed tightly to her face. This time, as she lay there panting in the aftermath, she felt less remorse than she did before. Now, she mostly felt bliss, and a growing resolve to do this again on Friday. *********************************************** She slept better that night, and all day Thursday she seemed reinvigorated. Mia kept thinking about what she'd done, how good she'd felt, and how much she wanted to do it again. She was amazed at how much better it felt with her shorts off, and she began to wonder how good it would feel if she humped her sister's pillow without panties on. To feel the soft fabric her sister slept on up against her bare sex, humping it back and forth... she shuddered each time she thought about it, and noticed that she began producing that slimy stuff in her panties each time she did. By the time Friday came around, every nerve in her body tingled with desire. She had already resolved to do this again two days ago, and now she'd been waiting all this time. It was all she could think about all day. Mia had been so aroused throughout her classes, she almost considered touching herself down there in the bathroom, but decided that would be going too far. So instead, she waited anxiously for the day to be over. When it was, she raced home as fast as she could. Just as on Wednesday, she dropped her bags at the door to her room, kicked off her shoes, and raced down the hall to Brittni's room. Her heart pounded and rose to the top of her chest when she entered her sister's room and looked at her rumpled bed. Quickly, she unbuttoned her shorts and pushed them down her legs. As she stepped out of them, she hooked her thumbs in the waistband of her panties, her heart pounding... and paused. She looked around the room and listened quietly, making sure no one was home. Of course no one was, she told herself. She was being silly. Then, she slowly began rolling her panties over her hips, then down her thighs. When they were about halfway down her thighs, she stopped again. Mia scanned the room, looking for an article of clothing she could use to remind her of Brittni while she did her business. She saw one of her sister's tank tops on the floor and was about to reach for that, when she saw, right next to it, a pair of her sister's panties. They were rumpled up and had obviously already been worn. Mia felt a twinge inside her chest and her stomach tied itself in a knot. Could she...? Should she...? And then, almost as if not acting from her own accord, she bent down and picked them up. A thrill raced through her entire body as she held her sister's panties in her hands. And then suddenly it became so obvious to her. THIS is where her sister's essence truly lay. This was the sexiest, most intimate article of clothing any girl wore, and if she thought Brittni's nightshirt brought her closer to her, Mia trembled at the thought of how close Brittni's panties would bring her. Clutching them in her left hand, she wriggled her own panties down to her ankles and clambered onto her sister's bed on her hands and knees. With her right hand, she reached out and grabbed her sister's pillow and began to stuff it into a ball beneath her hips. Oh, she could tell this was going to be good! When it was good and bunched up, she rolled her bare hips down over the pillow, sinking her burning sex down onto her sister's softness. "Uuuunnhh," she groaned, feeling the pressure directly against her mound. This was incredible, she thought. Instantly, she began rolling and grinding her hips around, feeling that incredible tingling wave spread throughout her body. Her eyes rolled back in her head and her hands instinctively balled into fists. She felt her left hand close around her sister's panties and she opened her eyes with a jolt. She had almost forgotten. Her heart thumping in her chest, she opened her hand, revealing her sister's wadded hip-huggers. Her heart pounded harder, thinking about where they'd been. Then, suddenly, almost without thinking, she brought them to her face, pressed them against her nose with her hand, and inhaled. Heavy, intoxicating musk filled her nostrils, spiced with a hint of tartness and sweat. The smell was raw, earthy, and pure Brittni. Mia imagined her sister wearing them during her dance practice and felt a jolt of energy surge down to her crotch. She humped the pillow harder and grunted into the panties. From that point on, everything inside her began to swirl around so fast, she was barely aware of what was happening. She felt sweet, soft pressure against her sex over and over, felt her sister's essence in her nose and face, deeper, fuller, and heard deep grunts emanating from her throat louder and louder. It began building faster and more intensely than she could process, and her body seemed to be controlled by something other than herself. She was humping, grunting, and sniffing so intensely she could almost feel her sister next to her, pressed against her... And then all at once, she was exploding - bursting and spasming all over her sister's pillow, grunting and panting into her sister's panties. It was glorious - so, so glorious, and Mia wished it would never end. Over and over she humped, breathing her sister's scent, prolonging the feeling for as long as possible. It was the longest, most wonderful, most erotic climax Mia had had yet, and Mia gave one final, prolonged thrust, holding it hard... before finally collapsing down onto her sister's bed, utterly spent. She had never felt such wonderful bliss in all her life. Her energy was completely drained. She could do nothing but lay there limply, her head swirling with the scents and images of her beautiful big sister. When she was finally able to lift her head from the mattress, she noticed she had left a puddle of drool on her sister's bed. Using Brittni's panties, she tried to wipe it up as best she could. Then, slowly, she began to roll herself off of her sister's pillow. The pungent smell of her sex wafted up and began to fill the room. But more problematic was the shockingly large wet spot she had left on her sister's pillow, right where her sex had been. Her eyes widened in a panic. Had that all come from her?! How was that possible? She looked around and quickly grabbed some tissues from her sister's nightstand and began to frantically wipe the pillow, but the liquid had seeped pretty deep. She cursed herself and began to wipe more and more, using tissue after tissue. When she realized it wasn't going to get any drier, she swore again under her breath and flipped the pillow over to the other side, hoping her sister wouldn't notice. Then she propped it back up against the headboard. After one more long sigh, the warm, comfortable bliss began to return to her. She basked in it for another minute, then got off the bed, pulled her panties up and put her shorts back on, then turned to walk out of the room. When she was halfway to the door, she stopped in her tracks. She turned, looked back to the bed, and saw her sister's panties rumpled up on the mattress. She bit her lip in contemplation, then quickly went to the mattress, grabbed her sister's panties, quickly stuffed them into the pocket of her shorts, and turned and left the room. *********************************************** That night, Brittni was exhausted. After slipping into comfortable panties and a large, oversize t-shirt, she brushed her teeth and got ready for bed. As she settled into bed, pulling the sheets up over her, she reached under her pillow to fluff it up. She quickly pulled her hand away, feeling a cold damp spot. Why the hell was the underside of her pillow damp?! She flipped the pillow over and, sure enough, there was a sizeable damp spot. She touched it again. Strange. Tentatively, she brought her nose close to it and inhaled. It smelled faintly pungent. She scrunched her nose, then brought it closer for a deeper sniff. Her brow furrowed as she recognized the unmistakable musky odor of female sex. What the hell...? How did...? Brittni's mind raced, trying to conceive of how this happened. The only other person who could possibly have been in her room between school and when she came home was her sister. Did that mean that Mia had rubbed herself on her pillow?! Brittni felt like throwing up. What could have possessed Mia to do such a thing? Why wouldn't she have just used her own pillow? The only explanation Brittni could think of was that her sister was disgusting and somehow trying to gross her out. Brittni quickly threw off the pillow cover and put on a new one, then tried to push those disgusting thoughts aside so she could sleep. ************************************************* Over the weekend, Mia made as much use of the panties she took from her sister's room as possible. As she got ready for bed that Friday night, she knew she wouldn't be able to settle down so easily. She kept thinking about the panties and what she'd done earlier that day. As she climbed into bed in her panties and a t-shirt, she brought her sister's panties with her and began to smell them. Her arousal instantly skyrocketed and she knew she'd have to do something about it. Quickly, she pushed her own panties down her legs and grabbed her own pillow, bunching it between her legs. It wasn't quite as thrilling as using her sister's pillow, but it would have to do. She pressed her sister's panties to her face and began to pump her hips against her pillow, feeling that familiar rush. She kept at it, grunting as quietly as possible, using her sister's panties to muffle her voice. Soon, she was groaning in climax, bucking her hips against her pillow in tight, hard thrusts. Exhausted and spent, she collapsed right there and fell asleep. In the morning, she woke up in nearly the same position. She opened her eyes to the sight of her sister's rumpled panties on the bed beside her head. Instantly becoming aroused again, she repeated the routine, sniffing her sister's panties while she humped her pillow to climax. She did this as often as possible throughout the course of the weekend, eventually losing count of the number of times she did it. It was quickly becoming a heavy addiction. ************************************************** All through next week, Brittni was shocked to discover yet another damp spot on her pillow Monday night, Wednesday night, and again on Friday night. Mia, the little bitch, was apparently sneaking into her room while she was at dance practice and doing her nasty little thing on her pillow. Brittni was so mad at her she could hardly believe it. She wanted to call Mia on it, but she didn't know how to do it without being really weird. What if, by some small chance, she was wrong? What would Mia think of such a weird accusation? Or what if Mia was really sensitive about it and collapsed in tears at Brittni's anger? Brittni was definitely upset with her, but she didn't want to hurt her. This was, after all, relatively harmless. In fact, it was all so weird and strange that Brittni began wondering about the reasons behind Mia's actions. What could possibly drive her to do such a bizarre thing? It wasn't until Friday night when Brittni was looking for a comfortable pair of panties to wear to bed that she made a startling discovery. Brittni was planning on wearing the same pair of panties she wore to bed a few nights ago, but they were nowhere to be found. She could have sworn she'd left them on the floor by her desk chair. But they simply weren't there. As she began to scour the room, she noticed other items of clothing missing. A tank top, and two more pairs of panties. What the hell? Was Mia stealing her clothes too? And then a strange thought hit her. What if there was a connection between her missing clothes and the wet spots on her pillow? Was Mia actually doing something with her clothes while she masturbated? The thought instantly caused a mixture of disgust, confusion, and intense curiosity in her. Brittni began to think about Mia's recent behavior. Her brow furrowed as she realized that Mia had been rather aloof lately, barely even speaking to her very much. And there were those strange looks from her... they weren't angry looks or dispassionate looks - they actually seemed rather sincere and had a certain, what was it... desire? This really weirded Brittni out. She'd read stories about obsession before and recalled that taking the person's clothing was one form of it - a way to somehow be close to them if they couldn't be close in reality. Was Mia developing some kind of sexual obsession with her own sister? It certainly would explain the missing panties. And the wet spots on her pillow. Brittni pondered this for a while and let her mind wander with possibilities of what her sister might be going through. She couldn't be certain this was the case, of course. It was entirely possible that she'd misplaced those panties somehow and didn't realize it. She decided that she'd check her sister's room tomorrow while she was out doing chores. It was the only way to be sure. Brittni lay down to sleep that night letting these thoughts flow through her mind, somehow now feeling that she was understanding her sister a little better. The next day after breakfast, Mia went outside to water the plants. Brittni, quick to seize the opportunity, ran to her sister's room and began scanning the room for any signs of her underwear or shirts. Nothing immediately apparent. She looked on the bed, the floor, Mia's desk, and even in her closet. No sign of anything. Maybe Brittni had been mistaken after all. And then, just as Brittni was about to give up, her eyes fell upon Mia's pillow. The most obvious of all places! She quickly went to her sister's pillow and lifted it. Her eyes widened and her heart began to pound as there, under her sister's pillow, were three pairs of her panties - the exact ones that had been missing. This confirmed everything. Mia was definitely using them to get herself off. She had somehow developed a strange sexual obsession with her sister's things. Brittni's heart pounded anxiously at the thought. What did this mean? Should she just let Mia go on doing this? Should she confront her? Her mind was a swirl of confusion. All throughout the rest of the day, and the next, Brittni wrestled with how to deal with this new information. Her first surprise was that she wasn't really mad with Mia for all this. She actually expected to be pissed, but she wasn't. She felt a strange kind of sympathy for her sister. As if this was something she couldn't control. But the biggest surprise came Sunday night as she lay down to sleep. The thoughts crept back into her head, and she knew that tomorrow was Monday. She would be at dance practice, and while she was, Mia was going to creep into her room. What would she do? Look around the room? Smell Brittni's things? Or would she simply drop her shorts and climb on the bed and stuff her pillow between her legs? Somehow, that thought made Brittni's heart pound. Would Mia search for a worn pair of her panties? What would she do with them? Hold them? Smell them? Would she do this as she rubbed herself against her pillow? Brittni was shocked to discover that her breathing was shallow and her face and chest felt hot. Was she actually getting turned on by thinking about this?? She tried to push the thought out of her mind, but somehow it kept coming back. It simply would not go away until she realized and accepted the fact of her own arousal at these thoughts. In fact, she realized that she was not only aroused, but ridiculously turned on - more turned on than she could remember being in quite some time. She decided that if Mia was going to get turned on by her panties, Brittni would have no problem getting turned on by these thoughts. So she went with it, thinking about them in more and more detail as her hand slid down between her legs and inside her panties. She pictured Mia on her bed, panties around her ankles, pillow stuffed under her hips, and sniffing her panties as she humped away. Everything rose within Brittni so fast, she barely knew what she was doing. Almost in a blur, she flipped her pillow around, quickly finding the dried little stain her sister left, and pushed her nose into it as she rubbed herself harder and faster. In almost no time, Brittni brought herself to one of the most intense climaxes she'd ever had, pressing her face deep into her pillow to muffle her involuntary shriek of pleasure, the scent of her little sister's sex heavy in her nostrils. ********************************************* It was Monday, and Brittni had only one thing on her mind. All day she tried to focus on school, but there was one thought that kept coming back to her over and over, which she was unable to shake. That afternoon, after school, her little sister Mia was going to sneak into her room and hump her pillow while sniffing her panties. It bothered her to no end that this was going to happen. Well, actually that wasn't quite right. What bothered her wasn't that it was going to happen, but that it was going to happen while she was at dance practice. Now that Brittni had pieced together what was actually going on in her room after school, she couldn't shake the thought of wanting some kind of absolute confirmation. She wanted to make sure it was actually happening. She wanted to observe Mia sneaking into her room... hear the sounds she made as she humped her pillow... and... watch her do it. Yes, that was it. Brittni couldn't hide that very simple fact from herself any longer. She wanted to watch her sister perform this bizarre, dirty, and incredibly erotic act. Toward the end of the day, one of her friends on the dance team, Jennifer, actually asked her if she was okay. Jennifer apparently noticed that Brittni seemed distracted, or "out of it." Brittni decided she could use this in her favor. She told Jennifer that she actually wasn't feeling that well at all, and was going to skip that day's practice. She asked Jennifer to relay the message to her coach and to pass on to her anything she would miss that day. Jennifer told her to take it easy and that she would see her on Wednesday. After class got out, Brittni decided she would have to plan this very carefully. She went out to her car and waited at least fifteen minutes - the time she knew it would take Mia to walk home from school. She wasn't sure how long it would take Mia to get down to business, but she figured it wouldn't be long. She started the car and quickly drove home. As she drove home, Brittni tried to play out every possible scenario in her head of how this would go down. First and foremost, she wanted to catch Mia in the act. But what then? The best case scenario would be to just watch from a distance, without Mia knowing she was there. That would give Brittni the freedom she wanted. But what if Mia saw her? She would have to be prepared for that. She knew Mia would be freaked out - there was no doubt about that. If that happened, she would have to hold her ground and be as calm and reassuring as possible. She wanted to let Mia know that she understood. That there was no reason to be upset. That this didn't actually bother her. But what then? Where would she go from there? All of this swirled through Brittni's head as she drove home. When she finally got to her street, Brittni parked two houses down, fearing that the sound of her engine would alert Mia to her presence. She quickly ran up to her house, and ever so slowly opened the front door, which was unlocked, and closed it behind her. She looked around. The house appeared empty. Her heart pounding, she quietly tip-toed up the stairs and very faintly began to hear the gentle creaking of a bed. Her heart pounded faster and she could feel herself moistening between her thighs. As she got closer, she distinctly began to hear muffled grunting - the unmistakable voice of her little sister. The itch between her legs quickly turned to a heavy throbbing and she ached to rub herself. As she began walking quietly down the hall, she noticed that her bedroom door was slightly ajar. Her heart pounded, nerves jangled, and she could now feel wetness oozing into her panties. She had never felt so alive, so excited, so... aroused. She took a deep breath. She must act quickly, she told herself. She didn't want Mia to climax before she had a chance to catch her. Carefully, Brittni approached her bedroom door and, her body on fire, gently pushed the door open. Her breath caught in her throat as her eyes took in the sight she knew would be exciting, but she was quite unprepared for how shockingly lewd and carnal the scene in front of her was. There, on her bed, was her sister Mia, naked from the waist down, panties around her ankles, pillow stuffed under her hips, her smooth, bare little butt pumping and flexing downward in rapid successive thrusts, rocking her whole body back and forth... and her face pressed deeply into a pair of Brittni's panties which lay on the mattress. Brittni's entire body received an intense jolt of energy that seemed to converge right down to the center between her legs, which began to burn like never before. Her knees felt weak and she began to tremble. She felt her sex drool heavily into her panties, the moisture spreading all throughout her crotch. Never in her life had she experienced a desire so strong to see an event to completion. She had to watch her sister finish this. No matter what it took. And just then, her sister froze, and Mia's head shot up like a bolt, eyes staring straight at Brittni standing in the doorway. Mia's mouth fell open, her body paralyzed in fear. "BRITTNI!" she shrieked. Brittni was surprised at her ability to keep her composure. In fact, she was far too aroused to feel much of anything else. "Mia, it's okay... don't get up," Brittni said as calmly as she could. "I... I don't want you to stop." It just came out of her. And it was the absolute truth. Mia held her frozen position. "W - What?" was all she could get out. "Please, Mia..." Brittni said, boldly sliding a hand down her abdomen, then over her crotch, which she cupped and squeezed. Juices oozed out in every direction, causing her eyes to roll back in her head. A trembling sigh escaped her lips, and she forced her eyes back down to lock on her sister's. "I need to see you. Please." Mia didn't move. Instead, her eyes followed Brittni's hand down to her crotch and watched her sister squeeze herself. At that moment, something inside her stirred. Deeply. Her heart began to pound again. Her breathing quickened. She looked back up to her sister's eyes and opened her mouth as if to speak. "Don't speak," Brittni said, reading her sister's face. Without taking her eyes from Mia's, Brittni grabbed her desk chair and pulled it to where she was standing in front of her bed. She sat down on it, eyes still on Mia's. Her hand began rubbing her crotch, squeezing it over and over. "Just put your face back in my panties, and do what you were doing before I came in. I need you to. Now." Mia was stunned. She tried to swallow, but her throat was dry. Her sister's words were firm and forceful. As if her body acted of its own accord, she slowly turned her head back to look at the panties on the mattress in front of her. She felt her heart leap to life at the mere sight of them. As if it was beyond her control, her head lowered to the panties and she inhaled. Energy surged through her body at the familiar and pungent smell of her sister's sex and her hips involuntarily pressed firmly into the pillow. The feeling was so incredible, it took control of her body. Without any conscious action on her part, she found her hips pumping into the pillow over and over again, driven by a pure primal need to increase the stimulation on her sex. "Mmmmmph," she groaned into her sister's panties. Brittni's jaw dropped at the sight in front of her. Not four feet in front of her, her beautiful little sister Mia had resumed pushing her hips into Brittni's pillow, her smooth round butt flexing again and again. Brittni heard her sister take deep breaths through her nose over and over, inhaling the scent of her panties from yesterday. But her eyes could not leave her sister's delicious young butt, so smooth and so tight, flexing and squeezing, her cheeks often crushing together on a forceful down-thrust, creating little dimples on the sides of her cheeks. Brittni's hand quickly slid inside the waistband of her shorts to cup her sex through her panties. She was shocked at how hot and swollen she was, not to mention the profuse amounts of fluid she had produced. This was by far the most aroused she had ever been in her life. When she squeezed her sex, hot liquid oozed out into her hand, spreading all throughout her crotch. Brittni groaned, her eyes still fixed on her little sister's butt. Mia had started off with slow, forceful thrusts, but her arousal quickly grew to pre-interruption heights as her thrusts picked up speed, becoming short and quick, bouncing the bed and causing it to creak. Her breathing quickened, and every few thrusts she would grunt - an adorable little high-pitched grunt that would send a jolt of energy through Brittni. Mia no longer cared that her sister was sitting a few feet from her. In fact, the only image that kept running through her head was the look on her sister's face when she had squeezed herself, her eyes rolling back in her head. Mia desperately pretended that the panties she was sniffing now were the ones that Brittni had squeezed herself through, dreaming of what her sister would smell like after something like that. She gripped her sister's sheets with her hands and pumped her hips harder and tighter into her sister's pillow. Brittni nearly drooled at the increase in her sister's pace, loving her sister's little butt flexing tighter and quicker. She gripped her sex hard, crushing the heel of her hand hard against her clit, her eyes staring intently at the two little mounds of flesh in front of her, squeezing and flexing and pumping. She heard Mia grunting more now - nearly one on every thrust - and watched her speed increase. Mia began to raise her feet onto her toes and dig the balls of her feet into the mattress as she pushed herself harder and faster. Then Mia gave a sharp squeak and froze - holding her pose for only a second before grunting heavily into the mattress and shoving her hips down hard, grinding them forcefully into Brittni's pillow. Brittni's jaw dropped as she watched her sister climax. Her hand was already grinding heavily into her clit and when Mia shoved her hips down hard, Brittni exploded in orgasm, her jaw dropping further still as she hunched over in her chair, determined to keep her eyes on her sister's tightly clenched butt as she rode out her orgasm. Mia's grunts and squeals filled the room, but Brittni fought to stay quiet, wanting to clearly hear every little sound her sister made. It all built to the most intensely mind-blowing orgasm of Brittni's life. She had no idea she could cum so hard. As she listened to her sister squeal and watched her little butt grinding on her pillow, Brittni shuddered into a second orgasm, grinding the heel of her hand even harder into her crotch. Mia's orgasm seemed to last forever, and consequently, so did Brittni's. The sight of her little sister in such intense pleasure magnified Brittni's own pleasure, pushing her into a third, and then a fourth orgasm, creating such intense, wonderful pleasure in her young body she never knew she was capable of. When it was over, Brittni lay slumped in her chair, hand still wedged down the front of her shorts, and Mia lay limply on her sister's bed, her face still pressed down into her sister's panties, breathing deeply as she caught her breath. The girls lay prostrate like this for quite some time, utterly drained, basking in the wonderful afterglow of their incredibly powerful orgasms. They each knew they experienced something powerful, wonderful, and taboo. In fact, the element of taboo was at the forefront of each girl's mind. They had just masturbated in front of each other. More than that, they had masturbated TO each other, having become incredibly aroused by each other. It was precisely that element, each girl realized, that made her cum as hard as she did. Brittni realized what they just did was incredibly rare and incredibly special. They experienced something very few sisters get to experience - genuine abandon right in front of each other. In fact, BECAUSE of each other. They shared a secret now that was dangerous, exciting, and incredibly erotic. Brittni was determined to hold onto this. After she caught her breath, Brittni pulled her hand out of her shorts and sat upright. She stood over Mia, who was still limp on the bed, breathing heavily, leaned down over her slightly, and said, "Tomorrow I don't have dance practice. Don't do this again until I come home, okay?" Mia felt a jolt of adrenaline run through her at these words. Brittni wanted to do this again! She raised her eyes to her sister's and saw the excitement there. Nearly trembling with anticipation, she nodded. Brittni smiled and with that, stood upright and turned and walked out of her room. ******************************************* Every day that week, as soon as Brittni came home, she would walk into her bedroom to find her sister already on her bed, naked from the waist down, gently grinding her hips against her pillow and smelling a pair of her panties. As soon as Brittni walked into the room, Mia picked up the pace considerably, pumping her hips in tighter, quicker thrusts. This prompted Brittni to quickly pull up a chair and begin watching the show. Toward the end of the week, Brittni started becoming less inhibited and actually took her shorts off as she watched her sister. It simply felt better that way. Every day, Mia ground her crotch into her sister's pillow while sniffing her panties and Brittni ground her hand against her sex, watching her little sister's butt work up and down on her pillow. And every time, each girl had a powerful, explosive orgasm that shook her entire body and completely took her breath away. Each girl also secretly hoped they had created a little ritual between them, to be repeated every day after school. It was the perfect way to unwind and it was the thing each girl most looked forward to every day. Barely any words were spoken between them, but there didn't need to be. All the communication happened with their eyes and bodies. Mia performing for her sister, allowing herself to get as completely into her pleasure as she wished - all the while knowing that every move she made excited her sister more and more. And Brittni, watching her sister's beautiful young body move in the most sensual and urgent of ways in a desperate attempt to climax as powerfully as possible. It was beyond erotic. It was pure bliss. And every day Brittni seemed to get more and more excited by the sight of her little sister's tightly clenching butt cheeks flexing, grinding, and shuddering against her pillow. She dreamed about those beautiful, tight cheeks in class, at home, and even in her sleep. She desperately wanted to know what they felt like - how smooth they were, how tight they were. If they felt just as amazing as they looked. But the next day was Saturday and the girls would be home with their parents all day. The day was incredibly frustrating for both of them, and while neither girl said anything to the other about their little ritual, they both thought about it all day long. Even as they said goodnight to each other that night, they both wanted to invite the other to do their little "game," but somehow it didn't seem appropriate with their parents home. They would just have to wait for Monday. But by Sunday, the girls were starting to get nervous that the other might have lost interest and wasn't as into it anymore. Frustration built between them all day long, and that night as they got ready for bed, each girl felt she should say something. But neither of them could find the right time. Then, just as Mia was about to go down the hall to her room, she saw Brittni coming out of the bathroom. Mia looked at her sister wordlessly, but expectantly. For a second, Brittni just stared back. Then, empowered by the intensely strong desire to continue their ritual, Mia spoke. "So..." she eeked out, "tomorrow... um... do you...?" Brittni's heart nearly skipped a beat and a thrill ran through her, making her body practically shudder on the spot. "You'd better believe it," she said, barely able to suppress a smile. A smile immediately spread across Mia's face, which she desperately fought to hide. She felt her face get hot and knew she was blushing. Her heart began to pound. Brittni still wanted to! "Kay," she said, shyly turning away, still fighting to hide her smile. "'Night." "'Night," Brittni said, breaking into a smile herself at her sister's adorable expression and mannerisms. Why did Mia have to be so damned cute?! She rolled her eyes at the thought and spun on her heels to return to her bedroom. In bed, Brittni was having trouble falling asleep. The adorable little way Mia nervously suggested they continue their little ritual had gotten Brittni all flustered. It meant Mia was probably thinking about it as much as she was. She suddenly couldn't wait for tomorrow. Then a thought suddenly occurred to her. She sat up in bed and flipped on her bedside lamp. She looked at the floor where her pile of clothes that she'd worn that day was and immediately noticed that her panties were missing. A devilish smile crept across her face as she realized Mia must have taken them while she was in the bathroom. 'Well,' she thought to herself, 'if Mia is having her own little fun right now, why can't I?' She turned her light back off, fell back to her bed, and slipped her hand into her pajama bottoms, imagining the sight she would be greeted by when she got home from school the next day. ********************************************** Of course, all day Monday was torture for the girls. The only thing they were thinking of was getting home and performing their little ritual with each other. For Brittni, it was doubly frustrating because she had dance practice that day. She didn't care though. She had been waiting all weekend to watch her sister do her thing that she wasn't going to let a silly thing like dance practice get in the way. The urge was simply too powerful. So she made up an excuse to miss practice again and headed home right after school. On the way home, she realized Mia probably wouldn't be ready, since she would assume that Brittni had dance practice. Her heart sank a little at not getting the arrival-home surprise, but at least they would do it, she thought. She pulled her car right up into the driveway and immediately went inside and up the stairs to her room. She stood in the doorway, shocked, her jaw almost hitting the floor. There was Mia, half-naked on her bed, just like she should be, her hair in cute little pigtails. Mia stopped her slow grinding and spun her head around to look at her sister. She smiled wide. "How did you know I'd be home?" Brittni asked. Mia bit her lip. "I didn't. I just... thought I heard your car down the street, and jumped up to the window to see. Sure enough, it was you, so it really didn't take much time for me to get ready." And with that, her butt cheeks seemed to give a little involuntary squeeze as her hips pressed into Brittni's pillow. Brittni still stood with her jaw open, drool ready to fall out. She quickly closed her mouth and swallowed. "God, you're amazing," she breathed, barely aware she'd said it. Almost instantly, a blush crept up Mia's face as a smile spread across her face, and Brittni felt her own face get hot. Brittni then cleared her throat. "Well, um... you can get back to... what you were doing," she said. Mia bit her lip, still smiling, and turned her head back toward the headboard and Brittni's panties. Slowly, Mia began to grind herself on her sister's pillow again. Quickly, after fumbling with her button, Brittni pushed her shorts down her legs and pulled up a chair. She shoved her hand into her panties, pressed it against herself, and groaned. It was one of the few times she made any noise of her own, but it was practically involuntary. She was shocked at how wet she already was as juices seeped out against her palm and spread across her crotch. Brittni fixed her eyes in front of her on her sister's hips, grinding in smooth, rhythmic movements, causing her butt cheeks to flex every so often. Brittni knew it wasn't until Mia was close to climaxing and thrusting heavily that her butt cheeks squeezed tight and clenched. It was what she most looked forward to. The girls masturbated slowly for a few minutes, taking their time, reveling in their pleasure, and working to a gradual build-up in hopes that their climaxes would be particularly intense. Besides, it's not like they were in a rush or anything as Brittni had come home early. It would be several hours before their parents came home. Brittni listened to the gentle rustle of the sheets as Mia rocked back and forth, and could hear her sister's breath gradually get heavier and shakier. She was breathing close to the mattress, her nose in Brittni's panties, and it produced a soft but noticeable sound. Then, suddenly, out of the blue, Mia thrust hard, clenching her cheeks tight. But just once. Then she went back to her gentle rocking. Brittni's eyes widened and her jaw dropped as a jolt of energy ran through her. That was hot, she thought. Another minute went by, and Mia did it again, this time giving a tiny little squeak. And again, Brittni jammed her hand against her sex, forcing out a trickle of juices. Was Mia teasing her? After another minute, she did it a third time, and it was driving Brittni crazy! Brittni studied her sister, watching her hips, head, and shoulders. Her face was buried against the mattress, nose-deep in Brittni's panties. She appeared to be completely lost in the moment, unaware of the effect those little thrusts were having on Brittni. Brittni focused her attention back on her sister's tight butt, hoping and praying it would squeeze again soon. And when it did, she nearly grunted out loud herself. God, she wanted to touch it so bad! Then a naughty, incredibly thrilling idea hit her. She wondered if she could get away with it. And then, after Mia's butt clenched again, she realized she didn't care if she got away with it. She was going to do it anyway. Slowly, she stood up and hooked her thumbs in the waistband of her panties, and pushed them down. They fell to her ankles. She slowly stepped out of them and walked around to the foot of the bed. Carefully climbing onto the bed, she saw that Mia hadn't changed her movements. She walked on her knees up to her sister's body. The view of her butt from this angle was incredibly thrilling, and she felt her sex twitch and ache. Slowly, Brittni walked forward, straddling her sister's legs. When she got close to Mia's knees, that's when Mia suddenly jerked her head up and whipped it around to look at Brittni. Brittni felt the shock and electricity of her sister's eyes on her. She was completely naked from the waist down, on her knees, directly behind her sister. Her mouth was open and her breath was shaky. She looked at Mia with a mixture of pleading and desire. "Mia..." she breathed, practically in desperation. "Oh God... please..." Mia seemed to understand as she looked down at Brittni's private region, then back up at her face. Mia softly bit her lip, and then slowly turned her attention back to her sister's panties on the bed. And slowly, ever so slowly, she began to grind her hips again on the pillow. Brittni felt a fire burn within her like never before as she watched her sister's glorious, tight young butt begin to work around again. Mia was going to let her do this. Brittni let out a trembling sigh and, eyes focused on those wonderfully smooth, round globes, began to walk forward again. She moved until she was directly straddling her sister's hips. As she stared down at her sister's butt working and flexing between her legs, she felt a trickle of her own juice run down the inside of her thigh. Then, placing a hand on her sister's back for support, she slowly lowered herself down to those tight, rotating globes. Her sex made contact on one of Mia's up-thrusts and Brittni immediately threw her head back, gasped, and pressed her full weight down onto those soft globes of flesh. "UUUUUUuuuuuuunnnnhhhhhhh," Brittni groaned involuntarily as the softness spread up into her crotch. It was so warm, so soft, so wonderful... she had never felt such incredible bliss in her life. Brittni's eyes rolled back in her head as her chest heaved. Mia's butt was tight and firm, her hard little muscles tensing and flexing as she ground around on the pillow. "Ohh my... OOhh Goddd...!" she gasped as pleasure coursed through her body. It was the most wonderful sensation imaginable. It wasn't quite a full-blown orgasm, but more like a subdued, low-level continuous one. She just sat there, letting Mia grind around, feeling the wonderful sensations flow through her. She sat like this, head back, eyes closed, for nearly a full minute. And when she finally rocked her head back downward and laid eyes on her little sister beneath her, head buried against the mattress, sniffing her panties, Brittni felt a renewed jolt of energy course through her. Her mouth fell open and she began to rotate her hips around against her sister's butt, grinding her slick wet sex against her sister's tight flesh. It wasn't long before the rotations of her hips turned to thrusts back and forth. Brittni's jaw dropped at the sensation of the thrusting, noticing a considerable increase in stimulation and pleasure. She leaned forward, placing her hands on Mia's back and arching her lower back slightly to apply more direct pressure against her clit. Her jaw dropped even wider as the soft pressure of her sister's butt flexed and worked against her clit. "Unh!" came a squeak. It wasn't Brittni. Suddenly Brittni realized this was having a pleasurable effect on Mia as well. Brittni thrust her weight down against her sister, forcing Mia tighter against the pillow. "Uhnf!" Mia grunted again. Brittni now began to thrust against her sister's butt in earnest, pumping her hips back and forth tightly against her Mia's firm, tight young cheeks. She felt Mia push back against her and it only made her thrust harder. Each girl fought desperately to stimulate herself frantically for a minute until they quickly found a rhythm together. Mia lifted up on Brittni's back thrust, and Brittni's tight forward thrust jammed her hips down into the pillow. They worked this rhythm over and over, building each other's heat, their breathing hot and heavy, their pulses quickening. Brittni could feel the folds of her sex sliding along the cleft between Mia's cheeks and when Mia flexed tight against the pillow, she squeezed them between her firm globes. Brittni worked the tight cleft of her sister's butt, wedging her mound against it thrust after thrust. "Uh... Unh!" Mia grunted suddenly, and Brittni doubled her efforts. Brittni leaned forward further, placing one hand on the mattress and gripping the sheets in her fist as she pumped hard and tight against her sister's butt, urging Mia's hips harder and faster. Brittni could feel it build and knew it was going to be huge. She pumped hard and tight over and over, thrusting her folds between Mia's tight cheeks until Mia grunted again. "UH! UHHNNH!" Mia squealed, thrusting her hips down and clenching her cheeks tight. Brittni felt herself peak and rubbed her sex tightly along her sister's clenched cleft, feeling the rock-hard muscles tremble and twitch against her. "UUNNH! OH GODDD!" Brittni cried out as she thrust once, twice, and finally exploded against her sister's still-clenched hard butt. It was the most incredible and powerful orgasm she'd ever experienced. Her eyes rolled back in her head as she felt full and complete release against her sister's tight, clenching butt. Mia's butt convulsed beneath her, grinding, clenching and tightening as she rode out her own orgasm. The sensations were unbelievable. Brittni was immediately aware that her sister's butt was now coated in her slick juices, which she was only spreading around with each thrust. The slickness helped lessen the intensity of the friction against her clit and she groaned at the pleasure it produced in her. Brittni thrust her sex hard against Mia's slick butt over and over, drawing out her orgasm through several waves, until finally spent, she leaned back heaving and catching her breath. Both girls panted heavily, reveling in the afterglow of their amazingly intense orgasms. If the first orgasm they had in front of each other was hot, it was nothing compared to this. This had utterly drained each girl completely. The contact against each other had been the undeniable factor that made them cum so hard. Brittni realized this and it rattled around in her head as she caught her breath. After a few minutes, she slowly gathered her strength and began to sit upright again. Placing her hands on the small of her sister's back, she gently leaned down and whispered, "Thank you." Then she slowly climbed off of Mia's limp, heaving body, grabbed her clothes, and walked out the door. *************************************
