Date: Wed, 13 Jun 2018 23:51:51 -0700 From: Jojo Starr Subject: Back from College - Chapter 4 BACK FROM COLLEGE Chapter 4 There was hardly a waking moment when Brie wasn't thinking about Jill. Her evenings were spent plotting and planning the various things they would do together and her mornings were spent in agonizing torture, awaiting the moment when they would be able to do them. When they were in the same room together, Brie couldn't keep her eyes off her sister. When they weren't in the same room, Brie couldn't stop thinking about her. Hell, she even dreamed about her! Brie supposed this was what love did to someone. Only this was a very special, very specific kind of love that certainly didn't happen to just anyone. Brie simply couldn't stop marveling at that. Seriously, what were the odds? First of all, what were the odds that two girls 11 years apart would be attracted to each other and start a relationship? Pretty low, she figured. Then what were the odds that the ages of those girls would be 23 and 12? Far lower. What were the odds of those girls being sisters? Almost none. And finally, what were the odds those sisters would enjoy a domme/sub relationship centered around bondage? This was truly something to treasure. There was no one else out there like them. As Brie lay in bed that morning, she replayed the events of yesterday and felt a wonderful thrill at what they had done. Tying up Jill in the middle of the house like that? Wow. What a rush. And humping her face like that? Oh God. And then Jill cumming from that vibrator and Brie feeling her body as it contracted... Brie had to fan herself with her hands just to cool off. As Brie got ready for the day, she went over her plans again for their next encounter. She wanted to make sure she had everything ready ahead of time so they could get started right when she wanted them to. All of the preparation was getting her hot and she knew the wait would be excruciating. But she also knew that Jill would be waiting too. And that was part of the fun. She loved teasing Jill - pretending like she wasn't interested in their little games until the last second. It was something she did yesterday and something she would do again today. It definitely heightened the tension, but it was also incredibly frustrating. What made it even more frustrating was the fact that Jill seemed to be teasing her as well, by wearing short shorts or tight t-shirts and walking around Brie as if she had no idea what effect it was having. She even seemed to bend over a little more than usual in Brie's presence, which certainly didn't help Brie's already frustrated body! It was nearly 1pm when they had taken a break from all the projects their parents wanted them to work on. Brie was lounging on the couch looking at her phone and Jill had just finished getting herself a snack. Jill came into the room, looking gorgeous as ever, and casually sat down in the recliner, across from Brie. Brie looked at her, then went back to her phone. Out of the corner of her eye, she could see Jill fidgeting, obviously restless. She pretended like nothing was out of the ordinary. After another minute or two, Jill sighed. "So, um..." she started. "So what?" Brie said, not looking up from her phone. "It's, like, 1 o'clock," Jill said. "So?" Brie said. Jill fidgeted again. "Do... do you...?" Brie suddenly cut her off. "Oh, that reminds me," she said. "Mom asked you to scrub the shower doors the other day, remember?" Jill looked stunned. "But... but I--" "You better go do it. Don't want to get her upset," Brie said casually. Jill huffed and got up from the chair, stomping off down the hallway. When she was gone, Brie set her phone down, biting her lip. Scrubbing the shower doors should take about 10 minutes, which would give her just enough time. She ran to her room and quietly gathered the supplies. After Brie set everything up, she waited for Jill to finish. After another minute or two, she heard some cupboard doors close in the bathroom. "Okay, I'm done with the stupid shower doors," Jill called out. "Go to your room," Brie called back. There was a pause. "What?" Jill said, more out of incredulity than lack of hearing. Brie couldn't believe how disobedient Jill was being. "Just for that, I'm going to make sure you suffer extra today," Brie stated matter-of-factly, loud enough for Jill to hear. Brie waited. Jill was quiet. She then heard Jill softly walk down to her room. There, she knew Jill would find a note on her bed, along with a pair of dark red satin panties. Jill would read the note, which read: 'Come out to the living room wearing these and nothing else.' Brie waited, every nerve in her body tingling with anticipation. Her pussy ached, just thinking about what her little sister would look like when she came down from her room. She was surprised - but maybe she shouldn't have been - that she didn't have to wait long. About three minutes later, Jill stepped out of her room and began walking down the stairwell to the living room. Brie watched, her nipples hardening, her breathing shallow, drinking in every inch of her sister's beautiful body. The satin panties fit her perfectly, creating a nice contrast against her creamy, smooth skin. Everything else was exposed as Brie traced her eyes up Jill's smooth, young legs, over those wonderful panties, up her tight, flat belly, and up further to her tiny breasts, which jiggled ever so slightly with each step Jill took down the stairs. Jill's face was alert but compliant, meek and submissive, with just a hint of pink creeping up around her neck and cheeks. She knew Brie was watching her, taking in her nearly naked form. And that little blush thrilled Brie terribly. "My God, you're beautiful," Brie said, almost involuntarily. It was true. She'd never seen a more gorgeous or sexier form descending down toward her. Jill was simply angelic. Jill stepped down into the living room and stood looking at Brie, awaiting instructions. Brie took another few seconds to eye her little sister up and down, allowing herself to moisten just a bit further. Then she picked up one of the pieces of rope she had and told Jill to turn around. She'd been doing research and this was time to finally try out something new. Her goal was a chest harness, which included Jill's arms bound with it. "Turn around and place your wrists together at the middle of your back," she said. Jill did as she was told and Brie then proceeded to tie Jill's wrists together with her elbows bent, wrapping the middle of the rope around several times and securing it with a square knot. She then brought the ends of the rope up to just below Jill's shoulders and held them at a right angle, wrapping the ropes around Jill's front, then back around again, cinching off the first part behind her back. She went back around Jill's front one more time, then tied the ropes off behind her back before bringing the ends up through her armpits and around the front ties on both sides, pulling it tight. Brie then wrapped it around the center behind Jill, and wrapped it twice again around Jill's front, this time about halfway down her arms just below her breasts. She cinched off the bottom ties the same way she had at the top and secured them behind Jill's back, pulling everything tight. Finally she brought the ends over Jill's shoulders and down through the bottom ties, criss-crossing them over her breasts. This had the effect of pulling the bottom ties up tightly under Jill's breasts, causing them to stick out and making them look a little bigger than they really were. When she was done tying off everything behind Jill, she told her sister to turn around so she could see her. Jill did so, and immediately Brie's heart began to beat faster. It was absolutely beautiful and she loved the way Jill's little boobs were squeezed and sticking out. "How does that feel?" Brie asked. Jill's face was flushed pink. "Goo- um... fine," she said. Brie smiled. "Can you move your arms?" She watched as Brie struggled a little, but neither her wrists nor her arms budged a fraction of an inch. Jill shook her head, her blush deepening slightly. Jill looked so tantalizingly scrumptious with her upper half so tightly bound the way it was, Brie had to fight the urge to throw her sister to the ground and have her way with her right then and there. So she bit her lip, took a deep breath, and composed herself. "Come over here," Brie said, pointing to a spot on the floor. "Stand right here." Jill walked over, noticing a thick rope stretched across the middle of the living room floor with several large knots in it, each spaced about a foot apart. One end was lying loose on the floor, and the other end was secured to a hook in the wall that she hadn't noticed before. It was about chest level. "Put one foot on either side of the rope," Brie said. Jill did as she was told, standing over the rope with one foot on either side. Brie then went behind her to pick up the loose end of the rope. She brought it up all the way until it was up against Jill's crotch, then brought it level with the opposite end secured to the wall, pulled it tight, and tied it to one of the rails on the stairwell behind Jill. Brie pretended to ignore the gasp her sister made when the rope pulled tight against her crotch, but in reality it made Brie's pussy twitch wonderfully. The rope was now in a V shape, the ends raised to chest level while Jill's crotch rested at the low point of the V. Brie then stood back and admired the scene in front of her. Her beautiful 12 year-old sister was standing in the middle of the living room wearing nothing but dark red satin panties, her upper half bound in a tight chest harness with her wrists tied high up the middle of her back. And to top that all off, a thick rope now ran quite snugly through her sweet little crotch, stretching from one end of the room to the other. There was no way Jill was able to step over the rope. She could only move forward or backward, and there were large knots along the rope both in front of and behind her, each spaced about a foot apart. Brie walked around toward the front of Jill, noticing as she walked that her panties had become quite wet. She looked down at the rope between Jill's legs and noticed it was pulled up tight right between her young lips, which seemed to envelope the rope on either side. The sight of the rope disappearing into her sister's vulva caused Brie to shiver with delicious excitement. Brie smiled at her sister. "What's that feel like?" she asked. Jill looked down at herself, her breathing shallow. "Uhmm... uhhhhmmmh," she began, presumably searching for the right words. Brie's grin widened. She had a pretty good idea how it felt. "Does this tickle?" she asked, placing a finger on the rope and plucking it gently. "HHhhhuuuhhh!.... HhhhhUUUhhhhh," Jill gasped, rising to the balls of her feet and shifting her weight from one foot to the other. She swallowed then took another breath. "Uh-huh," she finally managed. Brie grinned, then stood back. "Okay," she said. "Now walk forward. Keep going until I say stop." Jill took a few shaky breaths, her big eyes focused on all those large knots in front of her. She swallowed, then slowly put one foot in front of the other just a few inches, walking on the balls of her feet. Her breathing was shallow and quick, her body practically trembling as the rope slid along her panties right between her tight lips. She hesitated as she approached the first knot. "Did I say stop?" Brie asked. Jill swallowed and continued forward. Brie watched carefully as the knot sank down toward Jill's crotch, then finally came in contact with it, right against where Jill's stiff little clit was. "HHHHhhhhHHHHHH!!" Jill gasped, her upper body jerking as she continued to walk, the knot sliding down between her lips, disappearing for a moment, then slowly reemerging from under her ass. Brie felt her own panties get hotter and wetter as she watched her sister walk along the rope, absolutely loving every tiny little jerk and movement of Jill's body. Jill passed over a second knot, which caused her to jerk harder, then a third. Her gasps grew even louder, her legs trembling with each step. As Jill got closer toward the wall where the rope was secured into the hook, the angle of the rope against her crotch increased. The hook was about at chest level, considerably higher than her crotch. Brie felt butterflies in her stomach as she watched the rope get tighter and the angle get sharper and sharper. Jill was walking even higher on her feet now, nearly on her tip-toes due to the height of the rope. Brie watched as Jill approached the sixth knot, her entire body trembling. "Stop," Brie said. Jill's eyelids fell closed with relief as she stood there on the balls of her feet, her legs shaking. "I think this needs a little something to complete the picture," Brie said, walking over to a small shoebox. She opened it and came up next to Jill holding a large black ball gag. "I think this should do the trick," she said. "Now be a good girl and open up." Jill, her breathing still in quick, shallow pants, hesitated for the briefest of seconds before opening her mouth. Brie shoved the gag in, pulling the straps tight behind Jill's head, securing it in place. Brie stood back and now the sight before her had her fighting every fiber in her body not to shove her hand in her pants and bring herself to one hell of an explosive orgasm. She had to take a deep breath herself, and when she exhaled, it was rough and shaky. "Okay," Brie said. "Now go ahead and back up. Go as far back as you can." Jill, her face now pink after the gag, twisted her head over one shoulder, then over the other, and slowly began to step backward, her legs still shaking. Brie watched as her sister slowly backed up, the rope running straight between her sister's lovely ass cheeks as she approached the first knot. The rope was so tight it looked like it was entering Jill's ass about halfway up her cheeks, as if she was gripping the end of it between them. Brie could only imagine the sensation of the rope sliding straight down along her sister's tight little anus as she moved backward. Brie watched closely as the first large knot wedged itself right between Jill's tight young cheeks and slowly began to disappear between them. "Nnn-Nnnngghh," Jill groaned through the gag as the knot slid under her, undoubtedly dragging roughly along her anus and then directly against her tight pussy hole. Brie's body was on fire as she watched her trembling sister recover from the first knot and continue walking backwards. She was delighted to find that this backward motion was causing Jill's panties to stretch and ride higher and higher up her delicious young cheeks. Jill approached the second knot, the rope still sliding under her. She gasped just as the knot passed between her cheeks and lost her balance slightly just as the knot was directly underneath her. She grunted as she desperately struggled to readjust, the knot no doubt twisting and churning firmly against her little anus. Brie squeezed her legs together, delighted that Jill chose such a wonderful moment to lose her balance. The look of desperation on her sister's beautiful gagged face was absolutely priceless. Jill managed to center herself and slowly continued on her backward journey. "Hhhnnghh!" she grunted as the second knot passed underneath her, emerging from between her tight pussy lips. Brie followed Jill closely, absolutely loving the view of her sister's ass in those tightly stretched, high-riding panties. As Jill approached each knot, Brie first watched her from behind as the large knot disappeared between her sister's tight cheeks, and then shifted her body around so she could watch the knots emerge from the other side, separating Jill's young lips wider as they came into view, then rubbing roughly up the length of her slit as Jill continued to move backwards. Every single knot caused Brie's panties to get wetter, and by now they were soaked through. Jill was two-thirds of the way down the rope now, and the angle against her butt was getting sharper. She had grunted quite loudly at the last knot and was taking smaller steps now as she went. Her breathing was heavy and ragged and Brie could almost detect anxiety on her sister's face as she approached the next knot. Brie knew that the knots were affecting Jill quite acutely, and it was thrilling to watch. "Good girl, keep going," Brie said, walking along with Jill just behind her. Jill moved slowly, inching her way toward the next knot. She squeezed her eyes shut, breathing heavily. At a sharp angle, the knot pressed itself between her cheeks. Jill squeezed her eyes tighter, biting down on the gag. "NNnggh!" she grunted loudly, pausing with the knot wedged between them, just barely visible to Brie. "I didn't say to stop, did I?" Brie said. Jill inhaled sharply and continued backwards, her face twisting up as the knot went deeper. "NNNFFF!" she grunted as the knot slowly emerged from between her front lips. Brie grinned. This was too much fun. She watched the anxiety increase on her sister's face as she approached the next knot. Again, Jill slowed down as she got within an inch of it and squeezed her eyes shut tight as she bit down hard on the gag. Brie felt like she'd never been more excited in her life as she watched her sister slowly back up against the next knot, rising up to nearly her tip-toes. Brie bit her lip, almost feeling the same tension Jill was as she worked her way through it. "MMNNNFF!" Jill growled, her body shuddering lightly as the knot emerged from her front. Brie's pussy twitched as she wondered whether Jill didn't just have a small orgasm. If she did, however, it didn't provide much relief. Jill was still quite alert, tense, and anxious - which was good, because Brie didn't want her cumming too soon anyway. At this point, Brie could tell that each knot was an ordeal. Each knot must have walked that fine line between tense discomfort and terrible pleasure, and Brie knew it must have been torture. She again watched her sister's face twist up anxiously as she approached the next knot at an even sharper angle, barely able to remain on her feet. She let Jill get within an inch of it before she said, "Stop." Jill let out a heavy but tense sigh, partially relieved that she didn't have to go any further, but still struggling to stay upright. Her chest heaved as she panted to catch her breath. She was a mess. Tense, twitching, legs trembling, barely balancing on the edges of her big toes, her face, neck, and chest red, and drool running out of the corner of her mouth down to her chin. The sight of her like that thrilled Brie to no end. Brie, doing her best to hide her burning arousal, stood up straight and looked around the room casually. "You know," she said, "something's... a little off." She furrowed her brow, trying to pretend she couldn't quite figure it out, letting her sister sweat a little. "I know," Brie finally said, trying to act like she just came up with something. "We need more light in here." With that, she went to the side window facing the backyard and pulled the blinds open. She glanced over at Jill and saw her eyes wide with panic, her body tense and upright. Brie then casually walked across the room, ducking under the rope near the wall, and pulled open the blinds facing the front yard. Jill was now bathed in light - bound, gagged, and straining in all her nearly naked glory. "There, that's much better," Brie said, turning back to smile at her sister. Jill's face was white with shock, her eyes bulging wide. She knew, as well as Brie did, that anyone walking past their house would be able to look in and see Jill in this compromising state. Moreover, every house on the block was two-storied, and any of the neighbors could look down through their backyard window and into their living room. Brie actually doubted any of this would happen at this time of day, but she certainly wasn't going to tell that to Jill and knew it wouldn't be much of a consolation even if she did. Brie watched her sister straining, panting, tense and nervous. "You look like you're having some trouble there," she said casually. Jill looked like she was struggling to stay standing. "This rope isn't too tight, is it?" Brie asked, reaching down to test it, plucking it with her finger. "HHHNNNNhhhh! NNNNnnngghh! HNNnnn-hnnn-hnnnnnnnggh!" Jill wailed and whimpered as the rope vibrated against her, her body jerking and twitching. Brie grinned. "I can only imagine how that must feel, sliding tightly against all your sensitive parts," she said, studying her sister's strained face. "Your clit must ache every time it rubs up against a knot, doesn't it?" she asked. "Hnnng, Hnnng..." Jill whimpered, nodding, her brow furrowed tightly as she recalled the sensation. "And what about your ass?" Brie said. "Do they rub and grind against your sensitive little asshole every time you walk over them?" "Nnn-hnnnng," Jill nodded slightly, a strand of drool dripping from her chin. Brie grinned. "I bet all your parts down there are a little raw and aching terribly, aren't they?" she said. "Nnnnngg-Hhhnnnnnnnngggh," Jill whimpered. "That's good," Brie said. "I want them to. And you know what? I'm gonna need you to walk forward again - especially now that there's so much more light to see you better." "Hnnnng, Hnnnnngg!" Jill whimpered in frustration, looking like she was almost begging to be freed. "I had a feeling you'd feel that way," Brie grinned, walking over to a bag. She pulled out a riding crop and walked back over to Jill. "So I'll provide a little encouragement for you. Now get moving," she said, smacking her sister's ass cheek with the riding crop. "NNNNNGFFF!!" Jill squealed, her body jerking up and forward. Slowly, Jill started moving forward, walking wobbily on her tip-toes, her face twisted up in a permanent wince. Her panting increased as she approached the first knot. "Good girl, keep going," Brie said, giving her sister light pats on the butt with her riding crop. Jill finally came to the knot, and just as it came into contact with her clit, her body tensed visibly. "Good girl," Brie said, swatting her sister more firmly. "Over the knot now." "Hnnnng...! Hnnnngh...!" Jill gasped, her eyes squeezed tight. She kept walking and finally the knot disappeared under her. "Nnn.... Nnnn-MMMNFF!" she squeaked as it finally emerged from behind her. "Good girl. That wasn't so bad, was it?" Brie grinned. Jill just continued panting, her eyes focused on the next obstacle. "I bet each knot feels like torture at this point, doesn't it?" Brie said, still smiling. Jill nodded tensely, her eyes still focused on the next knot. "I mean, the rope itself is already pretty tight and that alone must be doing terrible things to your pussy and ass. But then the knot comes along - rough, focused pressure on your poor aching clitty, sliding tightly along it before dragging right through your tight little folds," Brie said, making her sister relive the experience even in between knots. "Enough to give you a little jolt of pleasure, but not enough to provide any kind of relief. It must be absolutely exhausting." Jill panted heavily as she was subjected to her sister's words. "Oh look, here comes another knot now," Brie said. "Don't slow down on me now," she said, swatting her sister's ass a little harder with the riding crop. It was clear that Jill was struggling to maintain her pace as she approached the knot. "Now I know it must feel good at first," Brie said, "so just focus on the pleasure. Let it press against your clit... goood girrrl." "HHhhhnnnnnfffhhh!!" Jill squealed as the knot pressed into her panties. "Now keep going, but hold onto that feeling," Brie said. "Focus, focus... feel the pressure still on your clit." Jill was panting heavily as the knot continued underneath her, clearly trying to focus and follow her sister's instructions. Brie could tell it was difficult for her, and it made her insides swirl. Jill gave another slight twitch as the knot passed over her asshole and finally popped out from between her cheeks. "Good girl," Brie said. "You did very well!" Jill looked as if she was enjoying these few precious moments of semi-relief right after she passed over a knot and before she had to worry about the next one. At the rate she was moving due to her sister's encouragement with the riding crop, however, those seconds were painfully brief. "Are you ready for the next one?" Brie asked. "It looks a little bigger than the last one, doesn't it? I wonder why that is. I tried to make them all the same size. Oh well. Just focus on the pleasure. I know that's your favorite part of it," she said, keeping Jill's mind focused. Jill had already started breathing heavier, her temporary relief already behind her. "Don't focus on anything else," Brie said. "Don't worry about the windows being open or that anyone might see you tied up and gagged like this. It doesn't matter what they think. What matters is that you're listening to your big sister and focusing on the pleasure I'm allowing you to experience. Focus on that wonderful little jolt of pleasure that knot's going to give you and how generous I am for letting you feel it." Jill was panting so heavily she was making soft little mewling whimper sounds as she approached the knot, her legs wobbly. Brie wondered if this was a result of her being more conscious of the windows being open and how tightly tied and gagged she was. She hoped it was. "Here it comes," Brie said. "Now focus." Jill squeezed her eyes shut and bit down hard on the gag, a heavier strand of drool falling from her chin. "MMmmmmpphh!!" she squealed as the knot wedged itself against her clit. "Focus, baby girl, focus," Brie said, swatting her sister lightly with the riding crop. "Hnnnng...! Hnnnng...! Hnnnngg...!" Jill huffed as the knot slid under her, her brow tightening and her face twisting up tensely. "NNFFF!" she grunted as the rope bounced slightly as the knot popped out from under her ass, clearly having caught slightly on her anus. "Oh Jill, you did so wonderful, honey!" Brie smiled as she looked at her sister. Jill was clearly struggling terribly now. Her face was constantly tense, her legs so shaky they seemed they would give out at any moment, and a sheen of sweat was beginning to form on her brow and temples. Brie began to wonder how many more of these knots she could take before she collapsed. "Okay, stop right there," Brie said, and instantly Jill's shoulders slumped as she began panting heavily, gasping for breath. "Don't move." Brie walked to the end of the room where the rope was tied to the hook in the wall and carefully untied it. Jill heaved a massive sigh of relief as the rope went slack. Keeping hold of the end of the rope, Brie walked over to the other side and untied the end from the railing of the stairwell. Instead of letting this end fall, however, Brie looped it around the railing, pulling the end down and back to Jill. Brie then bent down and pulled the railing end through Jill's legs and then stood back up in front of her sister, holding both ends of the rope. Brie now effectively had created a makeshift pulley around the railing. She raised one arm high above her shoulder, pulling the rope back up against Jill's crotch, holding the other end tight. "Mmmmph!" Jill grunted, jerking forward as the rope was pulled tight against her crotch. Brie grinned. "Now I hope you don't mind me controlling the pace," she said, and pulled with her lower arm, sliding the rope down through Jill's crotch at a nearly 45-degree angle. She pulled slowly and watched as the first knot slid down over Jill's clit and underneath her. It was absolutely fascinating for Brie, as she could actually feel the knot sliding through Jill's crotch from the tension in the rope. Jill tensed, biting hard on her gag as her brow twisted up. Brie continued pulling, the second knot sliding through Jill's crotch as Jill tensed even harder, bending slightly at the waist. Brie kept pulling, the third knot sliding through, and on the fourth, Jill squealed. "HMMMmmph!" she cried, her body jerking forward. Brie grinned and stopped pulling. She then reversed direction, pulling up with her arm so the rope slid back under Jill, who instantly stood up straight, her back arching slightly. When Brie felt the first knot catch between Jill's ass cheeks, she was delighted to watch Jill's hips involuntarily thrust forward until the knot finally popped through, with a little wince from Jill. Jill's hips then rocked back to their normal position until the second knot caught her, whereupon her hips thrust out again. With each knot, Jill's hips thrust out and back, giving the impression that she was almost trying to hump the rope. "Do you want to cum?" Brie asked. Jill huffed, her face twisted up. "Mmm-HMMMN!" she squeaked out. "I bet you do," Brie said, grinning widely. However, she had no intention of letting her sister do so just yet. Brie shifted direction again, pulling the rope down through her sister's crotch - this time picking up the pace a bit. One knot went through, then two, three, and four, at the rate of a knot every two seconds. Jill squeaked on the second, her body jerking, and on the fourth she shrieked, her entire body bending at the waist, her thighs clamping together. Brie grinned wickedly. She knew Jill couldn't have cum - the stimulation was too quick and wasn't prolonged. But oh, it must have been quite torturous, judging by Jill's reaction! Brie reversed direction again, pulling the knots quickly up through Jill's rear, again watching her sister buck and jerk her hips. "Mmph! Mmmph! MMMMMPH!!" Jill squealed. And back down again, quicker, through Jill's crotch. "MMMMMMMNNNNNFFFF!!" Jill screamed as her body nearly doubled over, twitching and jerking from her core. "Up, up, up now," Brie said, pulling the rope tighter and raising her sister up until she was on her toes again. She knew Jill was terribly sensitive, so this time she went slower as she pulled the knots up through Jill's rear again, her sister whimpering softly. Jill's entire body was trembling and twitching. Brie had her right where she wanted her. Brie reversed direction again, pulling slowly through Jill's crotch. One knot went through as Jill jerked, but when the second knot came to rest against Jill's clit, Brie stopped. She pulled the rope taut with both hands, then slid the knot slowly down the length of Jill's slit, then slowly back up to her clit. "Hhhhhmmmmmmmmpphhhh," Jill whimpered, her body twitching, another strand of drool dripping from her chin. Brie repeated this motion slowly, dragging the knot down through her sister's slit and back up again, watching the pained expression on her sister's face get more and more intense. Jill's hips were tensing and rocking back and forth, her ass clenching tightly as her hips struggled to follow the knot. "I bet you reeeeeally want to cum now, don't you?" Brie said. "Mmph... Mm-hmmmph," Jill whimpered, her breathing getting deeper as the stimulation continued. "Walk forward," Brie said. "Get the angle of that rope tighter." Brie held the rope taut as Jill took a few steps forward, increasing the angle of the rope against her crotch to sharper than 45 degrees. "Stop," Brie said, holding the rope tightly, making sure the knot stayed against Jill's clit. The two girls were now only a few feet apart. "I bet this feels good, doesn't it?" Brie said, holding the ends of the rope as tightly as she could. "Mm-hmmph!" Jill grunted, her body straining and clenching. "You want to cum pretty badly, don't you?" Brie said. "Mm-Hmmph!" Jill grunted, squeezing her eyes shut as she nodded. She was desperate and Brie knew it. "Show me how badly you want it," Brie said. "Hump your little pussy against the knot. Show all our neighbors what a dirty little bondage slut you are and how badly you want to cum for them." Jill squeezed her eyes shut as her hips jerked forward, crushing her young folds tighter against the hard knot. "Mmmph!" she grunted, the stimulation driving her body on regardless of how her mind felt. She slowly began to pump her hips against the knot, clenching her ass tightly with each thrust forward as she stimulated herself. "Hmmmmph... Hhhmmmmmphh..." she moaned as her body continued, settling into a rhythm. Brie watched, fascinated as her little sister made these wonderfully sexy primal movements with her hips in an attempt to bring herself to orgasm. Jill was blushing intensely, her face, neck, and upper chest all bright red, no doubt from embarrassment at all the open windows and all the potential neighbors who could be watching her at that very moment - watching her bound and gagged, thrusting her satin panty-covered, 12 year-old crotch against a knot on a rope held by her older sister. But no matter how embarrassed she was, her hips kept thrusting, the need to cum greater than anything else she was feeling. Jill was panting harder. She shifted her weight, spreading her legs slightly, and bent at the knees, increasing the force of her thrusts as her hips bucked back and forth quite heavily. She was clearly desperate. Brie was shocked. She never expected to see her meek, submissive little sister move in such an urgently primal way. She was like a feral animal, feverishly humping away in a desperate attempt to get off, as if it were the only thing in the world that mattered. Considering how long and how heavily Brie tortured her, she figured it probably was the only thing in the world that mattered to Jill. Brie was just thinking how remarkably quiet Jill was being throughout all this when Jill suddenly gave a sharp squeak and doubled her efforts, humping the knot even faster. Brie's insides swirled with excitement. This was it. Jill was about to cum. "MMMMPHH!!" Jill grunted heavily, her hips jerking forward, clenching tight against the knot, her body shaking. "MMMMM-HMMMMMM-HHMMMMMM-HHHMMMMMMMMMMMMMFFFFFFFHHH!!!" Jill wailed, her hips moving slower now, grinding her clit against the knot as her body heaved and shook violently in orgasm. "Gooood girrrrrl," Brie said, now sliding the knot back and forth along Jill's slit as she came. "Cum for everyone. All our neighbors... and especially for me. Let them all see how badly you needed this. Let them see how dirty you can be, humping a little knot on a rope to such a powerful orgasm." "HMMMMMFF!... HMMMMMFFF!... HMMMMMFFFFF!!" Jill cried, her body quivering heavily as Brie slid the knot along her slit. Brie let her cum for another few seconds, then dropped one end of the rope, pulling it through the railing and letting it fall to the floor. Jill stood there in the middle of the room, her hips still bucking and jerking at the air as aftershocks of her orgasm continued to jolt through her. Brie watched her, pleased with how this was affecting Jill. She'd clearly had one of the most powerful cums of her life and was still reeling from it. Her hips were still jerking, her legs were shaking, and she was panting so hard little specks of spittle were spraying out from around her gag. She looked spent, as if she could barely hold herself upright. "You look like you're having trouble standing," Brie said, smiling. "Is it hard for you to stand right now?" Jill's face was still twisted up intensely. "Mm-hmmmmffh," she whimpered. Brie grinned. She stood there, watching her sister tremble for another few seconds, then walked up to her and put her arm around Jill's shoulders. "Okay, let's lean back now," Brie said, supporting her sister as she lowered her. "Slowly, slowly now," she said, lowering her sister to the ground. Brie lowered her sister until she was resting on her back, still panting heavily through her gag, her chest heaving. But she looked considerably more relaxed, as if she finally had time to rest. "Don't get too comfortable," Brie said, her hands moving down to unbutton her own shorts. "I hope you've got plenty of energy left, because now it's my turn," she said as she pushed her shorts and panties down her legs, quickly stepping out of them. Naked from the waist down, Brie knelt in front of her sister and reached for Jill's panties, grabbing the waistband and rolling them down her hips. Jill obediently lifted her hips, allowing Brie to pull them off, which pleased Brie greatly. "Oh my God," Brie said, noticing Jill's swollen, glistening pussy as it came into view. "That rope really did a number on you, didn't it?" Jill just nodded. Brie grinned as she tossed Jill's panties aside. "Well, I'm about to do a number on you too, and this time I wanna know how it feels." With that, Brie grabbed the rope and pulled it over to them, carefully laying part of it vertically along Jill's slit. Brie then grabbed one of Jill's legs and held it up and back as she walked up to Jill on her knees, straddling her crotch and the rope. She was so horny she could hardly stand it. Watching Jill walk along the rope for so long had gotten her hotter than she thought possible. "Let's see what it's like to have a rope sliding through your pussy," Brie said as she carefully positioned herself over the rope on Jill's slit and lowered herself down onto it. "Aaahhhhhh," she sighed, crushing her weight down against the rope and Jill's pussy as she rested Jill's leg up by her shoulder. "Mmmmmmmph," Jill groaned as pressure spread across her sensitive pussy once more. Brie then jerked her hips up, sliding her sex along the rope and along Jill's slit, sparks going off in her head and all throughout her body. "Oooohhhh yeahh," she sighed, sliding her hips backward, then back up again. "Oooh wow, this feels fucking amazing," she said, looking at Jill, loving the way her face was twisting up again. She jerked back and forth a couple more times, loving the way the rope felt sliding between them. It slid pretty easily, considering how wet they both were. "What about the knot?" Brie said. "How did that feel?" With that, she reached behind herself and grabbed the rope with one hand, pulling it through until a knot came to stop at the juncture of their pussies. "Ohh my GAWWWD!" Brie groaned as she rocked forward, crushing her clit against the knot and the knot against Jill's clit as Jill groaned, her head jerking up off the ground. "Holy shit, how did you TAKE this for so long?!" Jill just looked up at her, her face twisted up, drool leaking out of the corner of her mouth, unable to say or do anything. She was, however, panting quickly, indicating that this was having quite an effect on her. "Fffuuuuuuuckk," Brie groaned as she rocked herself back and forth on the knot. "I'm sorry, I can't stand it any longer. I can't wait anymore. Watching you walk that rope, each of those knots spreading your tight little lips, sliding under you, rubbing against your little asshole -- especially while you were tied up so tightly, wearing nothing but those sexy little panties, and, GAWD - wearing that tight fucking ball gag... How many neighbors do you think saw you? How many of our neighbors watched you hump that fucking knot until you came?" Brie was rocking faster now, sliding her pussy down the length of Jill's slit, then back up to the knot where she crushed it against both their clits. Jill's face was twisting up even more and she was beginning to blush hard as well. "I'd never seen anything so hot in my life," Brie went on. "I can fucking guarantee you anyone who saw you was playing with themselves while they watched you hump that rope. Guys and girls. Fucking rubbing themselves till they came watching you hump that fucking rope all tied up. I can guarantee you it was the hottest thing any of them had ever seen." Brie was pumping her hips so hard, the knot kept inching upward, away from their clits. Every so often, she had to reach behind herself to pull the rope tight again and slide the knot back into place, a task she found slightly annoying. "How many of them do you think are watching us right now?" she asked, watching as Jill's face blushed deeper. "How many of them are watching your big sister fuck you all tied up like this? How many of them are rubbing themselves right now, watching us? What about Kristen Thompson who lives behind us? She's just a year older than you, isn't she? Do you think she's watching us from her bedroom window? Do you think she's getting hot watching you all tied up like this and getting fucked by your sister? Do you think she's rubbing herself? Do you think she's gonna cum?" "Mmmph... mmmph... mmmmph..." Jill began to squeal with each thrust of Brie's hips. "I can't take it anymore," Brie said, grabbing the rope behind her and swinging the end up over her shoulder where she could hold onto it, keeping the knot taut against both their clits. "I'm gonna fucking cum. All over your tight, raw little pussy. And I bet Kristen Thompson is about to, too." With that, Brie doubled her efforts, fucking herself against the rope and Jill's slit at such a pace that it caused slick, wet noises as their pussies slid together and a smacking sound every time Brie's loins came into contact with the back of Jill's thigh. Every forward thrust also crushed both girls' clits against the knot as Brie could now firmly hold it in place. "MMMMMMMMMMMNNNHHHHH.... MMMMMMMMMNNNNNNNNNNNNFFFFHHHHHHHHHH!!" Jill screamed into the gag as her clit was assaulted. "Oh fuck, oh fuck, Omigod yesss," Brie panted as the pleasure increased, keeping her gaze fixed on her sister's twisted, heavily wincing, pre-orgasmic face, tightly gagged with a very wet and slobbery rubber ball gag. Brie fucked as hard as she could, the banging of the knot against her clit driving her absolutely wild and building one of the biggest orgasms she'd ever experienced. "OOOhhhhhh shittt... OOOOOMIGOOODD... OHHHH FFFUUUCCKKKKK!!" she cried as she felt herself climax. She held her breath as she broke her rhythm to give three sharp, forceful thrusts hard and tight against her sister's clit, crushing the knot between them. That's when she saw Jill cross the point of no return, screaming hard into her gag. Brie had never held her breath for so long. But it was worth it. "AAAAAAAAAAAAAAAAAAAAAAAGGGGGGGGGGGGHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!" she growled, trembling and shaking on top of her sister as they both quivered in orgasm. Brie ground her hips around against the knot, smothering it between them as she dragged her orgasm out, determined to keep Jill cumming as well. "UUNNNFFFFF!!" Brie grunted as she jerked her hips, bursting into a second orgasm and continuing to grind down against her sister. "HMMMMMMMMMFFFH!! HMMMMMMMMMMFFH! HMMMMMMMMMFFFHH!!" Jill was panting, her head raised, her entire body tense and taut, completely at the mercy of her sister who continued to grind the knot down tightly against her clit. "UNNNNHH! FUCK yeah... Oh my FUCKING God," Brie growled as she kept jerking her hips, trembling as her third and fourth orgasms washed over her. As Brie's orgasms began to ebb, she focused again on her sister's face. Jill's brow was still furrowed and tense, her mouth still stretched wide by the gag, her expression still strained - although nowhere near as much as when she was cumming. Brie couldn't help but chuckle. "So little sister... how was that?" Brie asked, still gently gyrating her hips around. "I assume you had more than one orgasm?" Jill nodded, her brow still tense. Brie smiled. "More than two?" Jill nodded again. "More than three?" Brie asked, her eyebrows rising. Jill hesitated a second, then nodded. Brie chuckled. "You couldn't tell how many you had, could you?" Jill shook her head. Brie laughed. "Well, I, for one, am spent." With that, she rolled off her sister and collapsed onto the floor next to her, breathing deeply. She could feel the cool air on her wet sex and smell the potent aromas of both herself and her sister. She lay there for nearly two minutes, luxuriating in the wonderful afterglow of her powerful orgasms. But as Brie continued to breathe deeply, the smell of herself and her sister in the room was causing her insides to stir once more. Brie turned her head and looked at her sister, still tied and gagged, hair matted to her face, her cheeks and chin covered with drool. The sight of her like that caused the stirring sensation in Brie to swell. She reached over and brushed some damp strands of hair out of Jill's face. "My God, you turn me on so much," Brie said, looking deep into her sister's eyes. Brie then reached around Jill's head to unbuckle the gag. As soon as the gag fell away from Jill, Brie's mouth was upon her, melting her lips into Jill's and sliding her tongue deeply into her mouth. The girls sighed deeply as they kissed slowly and passionately, massaging and caressing each other's lips, mouths, and tongues with their own. Brie could never get enough of the way her sweet little sister's mouth felt against hers, especially when they were locked this deeply and passionately. She caressed every inch of the inside of her sister's mouth before gently pulling back and smiling at her. The smile Jill gave her back melted her. "So did you enjoy that?" Brie asked. "Yeah..." Jill said, before looking off to the side and blushing a little. Brie rose an eyebrow. "But...?" "Well," Jill said, "it was a little scary. Especially after you opened the blinds. And it was really hard going over each of the knots, especially at the end." "Did you feel like any of it wasn't worth it?" Brie asked. "No," Jill said. "You looked like you had some pretty heavy cums there," Brie said. Jill's eyes rolled back in her head at the memory. "God, yeah," she sighed. "So would you do it again?" Brie asked. Jill blushed. "If you wanted me to," she said. The corner of Brie's mouth twisted upward. "This was even more embarrassing for you than the first time you wore the ball gag, isn't it?" "Yeah," Jill said, blushing again. "But you don't mind the ball gag now though, do you?" Brie asked. "Not really," Jill said. "Do you think you might get used to something like what we did today?" Brie asked. Jill furrowed her brow. "But what if we get caught?" Brie's mouth twisted into a smile again. "You leave that to me," she said. "You don't have anything to worry about there." Jill didn't look entirely convinced, so Brie continued. "Jill, you're a minor. You're only twelve. If anyone's going to get in trouble here, it's me." "But... I don't want you to get in trouble," Jill said. "Like I said," Brie went on, "just leave that to me. You trust me, don't you?" Jill nodded. "So?" Brie said. "Would you do something like this again?" Jill nodded. Brie grinned. "You know how hot it makes me when you get embarrassed, right?" Jill nodded again, her smile getting bigger. "I think you have stronger orgasms too, don't you?" Brie said. "Yeah," Jill said, half giggling. Brie just looked at her sister, getting lost in her eyes, marveling at how lucky she was. "God, I love you," she said. "I love you too," Jill said. ********************************************** To be continued...
