Synopsis: Sara is a teen girl who is dominated by her sister. Her sister is very kinky, very into pain and Sara loves all of it! But now there's a new playmate joining them...
"Well?" asked Vicky of the panting girl. "School got out 45 minutes ago and you should have been home 15 minutes ago. What's your excuse?" The panting thirteen year old looked up at her sixteen year old sister. Sara was a mess - sweat dripping off her nose and coating her body. The smell of her sweat was strong - unlike her sister, who was in charge of her when their mother was away, Sara was only allowed to shower when Vicky said she could - and this would be the third day that Vicky hadn't let her shower. She was trying to catch her breath, bent over with her hands on her knees, having run all the way home from school. She was wearing a very short skirt which showed off her long, lean legs, and a t-shirt with a sports bra under it. She didn't need a bra - her A-cup tits were very firm, her sister had made her wear it for other reasons. Sara's shoes had been tied together and hung around her neck, she had run the whole way home in bare feet. Her pack was very heavy, but she had not been given permission to remove it so on it stayed, despite how tired she was. "I'm sorry, Mistress, I was talking to some of my friends." In point of fact, Sara had known very well that she was going to be late. She'd planned it that way and Vicky suspected as much. They were both anticipating a very entertaining evening. Their mother would be away for another week and Vicky had little Sara all to her self. Sara was a beauty, thought Vicky. She couldn't wait to get her hands, and other things, on that slim little body. Vicky was 5'6" with dark hair and eyes and a nice athletic build. Wide shoulders, a narrow waist and her thin, flat belly made her c cup breasts stand out very nicely. Sara, her younger sister, was only five foot two inches tall, but had very long legs for her height. Like Vicky, she was very slim but with smaller breasts. When Sara was 10, shortly after she'd started begging to be her slave, Vicky had started to subject her sister's small nipples and small clit to vacuum treatments. Several times a week, when their mother was home, and daily when she wasn't, she would suck the girl's small nipples and clit into vacuum tubes and leave them that way for a anywhere from 10 minutes to a half hour. It was very painful, but over time, Sara had developed large nipples and a clit that was quite thick and stood out almost a half inch when aroused. It had also made them very sensitive and Sara was well suited to be a sex slave. The totally submissive teen would do anything for her sister. "I see," said Vicky. "Well, I think that your actions deserve a set of fifteen, don't you?" "Yes mistress," panted the little teen. Her feet hurt from running home, despite the fact that she was used to going barefoot. The high heeled sandals her sister had chosen for her to wear were too tall for running. Not to mention the backpack, which weighed over twenty pounds before including her books and other school things. Her sister had put two ten pound weights in the pockets of it and made Sara leave them there. If nothing else, the girl got a good workout on her way to and from school. But that was only part of the game that they played today. Since their mother wouldn't be home for another week, and today was Friday, Sara knew that she and Vicky would really be playing hard. Certainly they had started off hard. When she woke up this morning, before her sister, of course, Sara had crawled between her sister's thighs. A very messy pussy confronted her since she had eaten Vicky to several orgasms the night before and Vicky had made a point of not wiping her cunt after pissing several times during the night. Plus, both girls had sweat a lot during the night because of the heat. Normally, Vicky was quite clean, but not this morning. Since her hands were cuffed behind her with leather cuffs, Sara could use only her tongue to separate the sticky cunt lips and she slowly started licking her Mistress' pussy, the heady scent filling her nose. It wasn't long before Vicky was awake and pressing her hands to the back of Sara's head while the younger girl sucked and swallowed the whitish cream oozing from the cunt in her mouth. Finally, before Vicky started to climax, she rolled over putting her sister under her cunt. Then she sealed her pussy to Sara's mouth and slowly started to urinate. Sara swallowed the dark yellow, bitter flow as her sister ground her sweaty cunt onto her face. Vicky, meanwhile was harshly twisting and tweaking Sara's long hard nipples. After emptying her bladder, Vicky rode her sister's face until she came. She got off the younger girl and began to examine between Sara's legs. Sara, of course, kept her legs open with no prompting. The thirteen year old's cunt was red and matted with old cum. This would be her third day with no shower. White lube was oozing from the open lips and Vicky leaned down and inhaled deeply, loving the sweaty, musky smell from her sister's crotch. She loved the strong smell and taste that her sister got when she wasn't allowed to shower. Tonight, Vicky knew, she would give in to her temptations, but not this morning. Tonight she had a surprise for Sara. She teased the thick clit from it's sheath, rubbing the creamy scum that surrounded the organ over it to make it swell. When it was swollen enough and her sister was panting with need, Vicky attached the suction tube to the sensitive organ and pumped it up until Sara was begging her to stop. The clit was now sucked out to three quarters of an inch in the tube (Vicky had placed marks every quarter inch on all the tubes), and was an angry red. She then placed a tube on each of her sister's nipples and after securing her to the bed spread eagle, left her there, her tummy full of piss, her clit and nipples burning from the harsh vacuum. Sara's legs were spread almost in a split, and she lay there waiting for her sister to finish in the shower. When Vicky finished, she walked back into the room to admire Sara. The girl lay there suffering, a thin sheen of sweat covering her body. Vicky especially liked the shine on her completely bald cunt, and the sweat leaving trails through the thin, dark hair under her arms. When Sara had started to grow pubic hair, Vicky had gotten hold of a pair of electric tweezers from her mother. Her mother didn't use them anymore because, although they worked, the effect was painful and permanent. Every night, Vicky used the tweezers on Sara's mons and vaginal lips, painfully removing any hair that she found while sitting on the girl's face to stifle her screams. Usually, she'd whip her sister between her legs to sensitize the area, thus making the whole process more painful. Sara usually came from that - if she was given permission. To further increase her humiliation, Vicky forbade Sara from shaving her underarms and kept her from using deodorant. She knew the other girls teased Sara about having hairy armpits and that Sara got off on the humiliation. Today, in fact, one of the girls in the locker room told her she smelled like a whore and asked why she hadn't showered after gym class. Sara's cunt had completely soaked through her panties at that point and her unwashed, excited cunt was easily smelled. Naturally Sara couldn't tell her it was because she was her sister's slave, and had been forbidden to shower. So, head down and face beet red, she left the locker room. Sara's sports bra and panties were super tight, the bra smashing her forming tits flat for the entire day and by now, she was in a lot of pain. Since she was just developing, her breasts were often tender, especially her thick, baby-bottle shaped nipples and especially when her period was on it's way as it was now. Vicky always knew when her period was due and went out of her way to hurt her sister's sensitive breasts and nipples even more during these times. Today, after having her nipples suctioned for almost half an hour, Vicky had made her put on this sports bra. It was a size too small for her and designed for a completely flat chested girl. Sara was small, but not completely flat. Vicky had glued a thin layer of green pot scrubber plastic on the inside and Sara had been rubbed raw, salty sweat stinging her skin as the rough plastic caused her to sweat even more on the hot day. Her nipples, being so prominent, were in even more pain, and Sara wondered if they were bleeding. It wouldn't be the first time. Almost worse were the panties she'd had to wear. They were also a size too small for her and the same thing had been done to them. She'd been told she was allowed to pee only once while at school, and she'd followed those instructions like the slave she was. She'd been forbidden to wipe herself afterward though, and her urine and cunt juice had soaked the panties. Every step was agony, almost past her ability to get turned on by it, and she wished her sister would let her strip. "All right cunt. You wait here while I get the cane. Keep your arms out, shoulder height, and stand on the mat while you wait." "Yes Mistress." Their backyard had a high fence around it because they had a pool, so it was quite private. Vicky often tortured her sister outside because it meant that Sara would have to work extra hard to keep from screaming - in pleasure or pain, so that the neighbors wouldn't hear. The mat that Sara had been directed to was actually a metal grate for cleaning shoes. It wasn't sharp, but it was quite uncomfortable to stand on in bare feet. And it was hot from sitting in the sun all day. Vicky took her time returning, and tears and sweat were running down Sara's face from the pain in her feet and the ache in her arms. She was panting and trembling from the strain. Vicky walked up to her and lifted her arms over her head. Sara groaned in pain. Vicky leaned down and put her nose in the teen's armpit, inhaling the thick scent of her sweat. She was trembling with desire, but knew she would wait until after Sara's punishment before she would please herself or the girl. It was difficult though, the dark hair was matted with sweat, and Vicky longed to run her tongue through it and taste the salty liquid. "Strip slut. Time for your fifteen." Sara dropped her hands with a groan of relief and took off the backpack. She was so horny, consumed with lust and pain and prayed her sister would let her cum while she received her 15. A set of fifteen was harsh. It meant she'd get fifteen strokes with the thin cane on each ass cheek, her back, her belly, each breast, her mons and her cunt, which she would hold open with her own hands. After a day of being rubbed raw, it would be excruciatingly painful. But Sara got off on heavy pain and lots of humiliation and today had primed her for some serious action. She knew she'd most likely bleed, especially in the places that wouldn't show while she was dressed. Most of the marks on her belly and back would disappear, but it would be a week or more before the ones on her ass and tits would heal. She was surprised she didn't have any scars, but even when she fell and hurt herself with scrapes and cuts, she didn't scar. Plus, none of the other times her sister had bloodied her ass with the cane had scarred either. When she was finally stripped, she was told to bend at the waist. Vicky examined her body and, sure enough, her nipples, breasts, cuntlips and mons were red and raw from the constant irritation. Well, she hoped little sister liked the evening's finale. Thirty strokes of the cane were applied to Sara's ass. There were no warm up strokes, she was welted right from the get go. Vicky had split her skin in several places by the time she'd finished. Then onto her back - no blood drawn there, then her soft, thin belly. Surprisingly, Vicky drew blood with the final stroke, right at the bikini line. When it was all over, Each breast had a welt or two oozing blood as did her mons. Sara almost came when the cane hit her clit, but she hadn't been given permission, so she didn't - at the cost of a bitten lip. Vicky attached a collar around Sara's throat, cuffed her hands behind her and dragged her into the house on a leash attached to the collar. Sara was given a quart of water, then a bladderful of Vicky's piss as she ate her sister to orgasm. Vicky took her sister up to the attic and began to tie her down. There was a plastic tarp on the floor, and over that was a rough wool blanket. Since their mother never came up to the attic, the girls had made it their own playground. There were tiedowns in the floor and several innocuous looking pieces of furniture that could easily be turned toward very perverted uses. Sara's hands were uncuffed, then recuffed in front of her. Her hands were pulled over her head, and the cuffs tied to one of the tiedowns in the floor. Then, Vicky took a leather belt that they'd cut just for this purpose and laid it over Sara's middle. There were dulled tacks pushed through the belt, which pricked her skin. Vicky took a lava rock that just fit into Sara's bellybutton (if she really stretched it) but protruded about a half inch out the top into its place. She hooked some cargo straps to either side of the leather belt, then attached the straps to the floor and started to ratchet them closed. There was a ratchet on each side so that even pressure could be applied and eventually, Sara's waist was very constricted, hampering her breathing and causing the tacks to painfully push into her skin. The rock in her belly button was sharp and scratched the inside as it was pushed into her tummy from the pressure of the strap. Finally, each leg had a wide strap wrapped around it just above the knee and cuffs were attached to each ankle. Sara's legs were pulled into a very wide 'V' with her cunt at the bottom and her legs pulled straight. Then the straps on each leg and ankle were attached to the floor tiedowns pulling her until her tendons were stretched to the limit and her legs were almost on the floor. Sara was in agony, but the pain fired her blood, as did the strong smell of own her sweat and cunt. Vicky was now ready to begin the part that she liked the best. Slowly, she moved over Sara's stretched body, sniffing the strong scent from her underarms, running her fingers down the sweat soaked ribs of the girl. Slowly, she began to lick and suck the moisture from each armpit, cooing with delight as the salty taste and heady smell aroused her lust. Her fingers were busy between her own legs, pinching her clit sending jolts of pleasure through her body. After each armpit was shinning with her spit, she moved down to her sisters red, abused breasts and nipples she sucked and cleaned the salty sweat off each one, while using her fingernails and teeth on the swollen, painful nipples. Sara groaned with lust and was soon begging to be allowed to cum. "Of course, not little slut. But don't worry, I have something special planned for this evening and you'll get to cum all you want then." Sara whimpered and grit her teeth as her sister's tongue worked it's way down her grimy body toward her cunt. Vicky could smell it long before she got there. When she finally began to gently lick Sara's mons and inner thighs she was going wild with lust. The thick scent from Sara's unwashed, cummy crotch was making her crazy and her fingers were pulling and pinching her own cunt lips. She made herself veer away from her ultimate target and began licking the thin, strong thighs, bathing them in spit as she sucked the salty sweat beading on the skin. Finally, she could wait no longer. Sara's cunt was opened due to her excitement and the extreme position of her legs. White, creamy drool was oozing from the small hole and Vicky delicately used the tip of her tongue to gather up the first taste of her sister's gamy cunt. She almost came from the scent and the depravity of what she was doing. Slowly, she licked and sucked Sara's pasty discharge, and it coated her own lips and tongue, sticking to the inside of her mouth. Pulling back the hood of Sara's large clit, she nibbled and sucked at the base, cleaning the built up paste that was stuck to the enlarged organ. She cleaned between all the folds, swallowing all that she could, savoring the salty taste of old sweat and cum, sucking the gooey discharge that was mixed with traces of the day's urine. Vicky finally came as she stuck her tongue into her sister's asshole, sweat, girlcum and shit coating her lips and tongue. Sara was going wild, trying desperately not to cum and almost lost it as her sister pushed one long finger deep into her asshole. It came out coated in her shit, and Vicky used that as lubricant to stuff two more fingers into the girl, pushing hard and painfully against the rosebud. When she got bored with that, she pushed her shit covered fingers into Sara's mouth. Sara accepted the bitter digits, cleaning them as best as she could. Vicky, meanwhile, bent down and began to lick the remnants of Sara's shit from her asshole, pushing her soft tongue as far into the girl as she could. Sara was in a state, begging and pleading to cum, but Vicky wouldn't let her. "Don't worry love. Soon the real fun will begin. I have to go down stairs for a while, but I'll be back in a little while. When I do, we'll really start the evening." "Ohh, please Mistress, please, just one little cum? I'm burning up!." Vicky smiled and left her sister in the sweltering attic to go down stairs. By the time she heard Vicky returning, Sara was really in pain. Her legs being spread so wide coupled with the harsh wool on her whipped ass and back really hurt. She was covered in sweat from the heat and really had to take a piss. She would try to hold out, but if she didn't make it, it wouldn't be the first time she'd pissed herself waiting for her sister to give her permission. All the water, and her sister's piss that she'd drunk, was making her bladder cramp. She had to pant shallowly to keep the belt from cutting into her skin. Finally, she heard footsteps on the attic stairs. Vicky was coming back! But wait, Sara thought she heard more than one set of feet on the stairs. Vicky arrived with a big smile on her face and a strange girl in tow. "Sara, my dear little slave. I hope you weren't too uncomfortable waiting for us." Sara was whimpering with pain and a little apprehensive about the stranger. She and Vicky had never told anyone about their relationship. "Um, please Mistress. My legs hurt and I really have to pee," said the embarrassed girl. The stranger gave a low whistle. "Wow, you weren't kidding. You've been doing this how long?" "She's been my slave for about three years. Sara, I'd like you to meet Jane. She's going to help me to play with you tonight. You will follow her orders just like you follow mine, do you understand?" "Yes, Mistress." "Jane here is going to help me with something I've wanted to do to you for a while. Can you guess what that is" "No Mistress." "Well, Jane is a nursing student. She also works at a tattoo and piercing parlor." Piss leaked from Sara's bladder from excitement. She and Vicky had talked about it, but there'd been no way for someone as young as Sara to get it done. "So what do you think, Jane?" "Wow. She's pretty hot looking," Jane said as she bent down and took a hold of one, raw, swollen nipple. "We'll have to clean her tits up a bit, but her nipples are certainly big enough." "Excellent. I want a nice size bar through each. Big, but not big enough to keep me from continuing the suction treatments." "No problem. We can do that easy. But wasn't there something else you wanted me to show you how to do?" "Oh yeah," Vicky smiled. "That'd be good." Sara watched with interest as Jane pulled several sterile packets out of her large bag. Several lengths of rubber hose were also pulled out. "You go ahead and do it, and I'll guide you. We can start with the smallest diameter one and work up. When we start to get to the bigger diameter ones, I'll show you how the retention bladder works." Vicky's eyes were glowing with pleasure. "Cool. That last one looks pretty big though, you sure it'll fit?" "We'll have to see, but you'd be amazed at how much it'll stretch." Sara was getting a little nervous. She had no idea what they were talking about, and the discomfort her body was in was growing all the time. Her legs were really aching, her breasts and nipples burning and throbbing, and the fact that she hadn't cum yet was driving her nuts. "Here," said Jane as she tore open a package, "put some lube on the end of this." Sara couldn't see what "this" was and was getting even more apprehensive. Her sister was always finding ways of stretching her abnormally small cunt. The problem was that it always snapped back tight within hours. Something, Vicky said, that Sara's future Husband/Master and/or Wife/Mistress would really enjoy. But in the years that they'd been playing, they'd never found a way to stretch Sara's cunt for any length of time. Her asshole reacted the same way and both hurt like hell when Vicky decided to play, "let's see what we can fit in here" games. "Are you sure she'll need lube?" "Yeah, plus her cunt's filthy, so we don't want to irritate things too much and cause an infection." Vicky snorted, "Good luck. She's never been sick a day in her life." "You kidding? Not even a cold?" "Nope. Not even a sniffle." "Well, lube it anyway," said Jane. "OK." "Now, push on it until you're sure it's in and you feel a little resistance, then push hard to get past. Keep feeding it in until you get a stream. Here, we'll use these to keep her open." Sara was unable to look at her sister too well because keeping her head up required effort and she was too tired for that. Suddenly, she felt two hard pinches on her outer cunt lips. Clamps, she knew as she moaned and her body twitched in response. Her lust rose a little higher. She loved tight clamps on her cunt. Her lower lips were pulled until they were spread painfully wide, then pulled even more until she yelped. They remained held there. Then Sara felt something probing at her cunt... no at her pisshole! She groaned as her sister slowly fed the catheter tube up her urethra. It was a novel experience, the stretching and burning pushed into her body. Finally, it hit against something and her sister pushed even harder. Sara yelped because it really hurt, then she felt her bladder draining. Vicky was wildly excited having penetrated her sister in a new way. Jane too, was excited. She was as perverse as the other two girls, but at nineteen had more experience. She'd both been used as a slave and played the Mistress since she was seven. Well, she'd spent the years from when she was seven until she was sixteen as a sex slave to her Aunt and Uncle. Then they'd taught her the other side of things and now she loved being both. Piss began to shoot out of the thin tube, but Jane was ready with a pitcher, catching each drop as thirteen year old's bladder emptied. There was a remarkable amount of piss empting out of the girl. When it was finished, Vicky pulled the tube from Sara's body. Then Jane gave Vicky the next size up and they started again. By the time they got to the final size tube, four tries later, Sara was crying and begging. She'd never been hurt this way and it was getting beyond her ability to deal with the pain. That was when Jane started to lick her clit and Vicky began to finger her asshole. With the thick tube in her pisshole, which they also began to fuck in and out, they brought the girl to orgasm, screaming and crying in pain and pleasure. It was one of her most intense orgasms ever. But they didn't let her rest. They started to work the girl up again, but this time left her hanging. Jane removed the last tube after showing Vicky how the retention feature worked. Vicky was fascinated. Then, while they rested and idly teased the bound teen, playing with her body and each others, sharing Sara's piss between them as they worked each other, and occasionally Sara, close to orgasm. Finally, when they were all very aroused, it was time for Sara's piercing to begin. Sara was at the point where she'd do anything for an orgasm. First, they added more straps across her body, one just under her breasts and one just over them. They tightened them enough so that they cut into the girl's skin. Then, they added another strap across her throat which they tightened enough that it kept her from moving her head, but didn't interfere with her breathing... much. Finally, they wiped her tits down with alcohol, causing the girl to scream from the pain, and put a piercing clamp on one swollen, distended nipple. Jane clamped it far more tightly then she had to and made sure to roughly pull and tug on the sore nub. Vicky started to rub her sister's clit to offset the pain, when Jane turned to her. "What are you doing?" "Well, this is going to hurt a lot, so I thought I'd play with her clit some while you were doing it." "Don't. I want her to feel the pain. You can play with her clit after I've pierced this one. In fact it'd be great if you could make her cum after this piercing. Then the next one will hurt even more." "Damn, you're sadistic." "Yup. You want to do the other one," asked Jane? "Oh yeah," replied Vicky with an evil grin. "But I don't know how to do it." "Hey," replied Jane "You gotta learn by doing, ya know? That's how I learned." Sara was grinding her hips as much as she could into the pleasure giving finger. They still hadn't unclamped her cunt lips and her big clit was an easy target, ripe and exposed. "OK, time to stop playing with her clit. Let her calm down a bit." They waited until Sara was less aroused, but her panting continued because her bonds were too tight to take a full breath. She was afraid of how much it was going to hurt. Finally, Jane decided it was time. She got a firm grip on the thick piercing needle and slowly pushed it through the thirteen year old's nipple. Sara screamed, as well as she could, and tried to thrash around. She was bound too well to move and tears streamed down her face. Nothing had ever hurt as much as that. As the pain was slowly fading to something bearable, Jane sadistically pulled the needle out sliding the bar through her flesh in its place. Sara was barely able to see the surgical steel bar now piercing her blood red nipple. Blood was tricking out of the hole, but not very much - certainly less than she'd bled from the cane earlier. Sara became aware of Vicky licking and sucking her clit while working her fingers deep into her cunt. Vicky's fingers were coated with white slime and her tongue and teeth worried the thick clit in her mouth. Despite the pain in her nipple, Sara began to orgasm - at which time Jane started pulling and twisting the bar now through her nipple. Sara's body, as used to pain as it was, came hard from all the stimulus. As she lay there panting, Jane said, "OK, now we do the other one, while she's relaxed and not as excited. That should make it really hurt." Sara's mouth was too dry and it was too hard for her to do more than moan. Vicky was shown how to clamp the nipple and, under Jane's direction, slowly pierced the other nipple. Sara moaned and cried, thrashing weakly in her bonds. Her bladder voided, but there wasn't very much piss left for her to expel. When the bar was through, Vicky licked and sucked her to another orgasm. Jane was amazed, having known only a few people in her life that could cum that hard after so much pain. They decided to let their toy rest - if being tied in a strict hogtie with a huge ballgag in your mouth could be considered resting. Not to mention the fact that her hair was tied to her feet and they placed her on her stomach. Her newly pierced tits felt like they were on fire as they rubbed on the wool of the blanket. Vicky and Jane drank the rest of Sara's piss from the pitcher and played with each other for about a half hour, right in Sara's line of vision. Even after all she'd been through, this aroused Sara a great deal and Vicky knew it. Vicky strapped on an eight inch dildo - the biggest one that they'd ever manage to fit in Sara's cunt, and retied Sara on a bench, but with her legs spread even more painfully wide. She knew she was going to get royally fucked. Jane had disappeared downstairs for a moment. Sara was tied as she had been on the floor, except now she was on a bench. Vicky was able to pull her legs further down and back. Sara was stretched like a bow string. Jane returned and she stood spreading her ass cheeks over Sara's mouth. Sara looked up into a shit smeared ass crack. "Did you ever," asked Jane conversationally of Vicky, "have one of those shits were it was soft and gooey and coated your entire asshole? God, it takes forever to clean that with toilet paper. I'm so glad I don't have to use toilet paper now, it makes my sensitive asshole all raw." Looking down at Sara she said, "Make sure you clean it good, cunt. Vicky's gonna use that cane on your inner thighs while you do it and she's not going to stop until I'm satisfied." Sure enough, Sara felt a slash of pain on her stretched, inner thigh. She groaned with lust. Nothing made her feel more submissive than the humiliation of being used as a toilet. She could cum non stop with just the slightest of touches while being used like that and Vicky knew it. Another slash and Sara started using her lips and tongue to clean the shit from Jane's asscrack. It was soft and bitter and Sara had to work hard to clean it, but eventually Jane, who had herself cum while her asshole was being serviced, lifted off Sara's face. Few times in her life had Jane been fortunate to sink to this level of depravity. She was watching a young teen, just beginning to bud into womanhood, get her thighs welted with a cane from her sister, while the same girl, who's nipples Jane had just pierced, sucked fresh shit from her asshole. Jane was in heaven and came several times. When she rose off Sara's face, Vicky stopped whipping the girl's thighs, and Jane looked down onto the beautiful, shit smeared face of the girl and spat a wad of saliva directly onto her lips. Sara groaned and opened her mouth wide, hoping for more and Joan spat again, another large wad dropping into the girl's mouth. Overcome with lust, Jane got on her knees for a deep tongue kiss, smearing her own saliva and shit over her lips while her tongue plunged deep into the other girl's foul tasting mouth. Vicky, meanwhile, started shoving the huge dildo up Sara's cunt. It hurt like hell, but Sara started to cum anyway. She and Jane were cleaning the remnants of Jane's shit off each other's faces while Vicky pounded away at her sister. Finally, Jane put on another dildo and they switched places, Vicky slowly choking her sister with eight inches of soft rubber as the girl struggled to breath and Jane feeding more of the same into Sara's asshole. The only lube she used was from Sara's cunt, and it hurt like hell, but still Sara came again as her sister pulled most of the large, fake cock out of her mouth. Sara was getting very good at deepthroating. Finally, after switching places several times and Sara sucking either slimy cunt juice or her own shit from a dildo, they let her up. She was too exhausted to stand and they crossed her arms between her shoulder blades and tied her upper torso in rough hemp. Her middle was also constricted with several layers of hemp. They sort of suspended her from the ceiling so that Jane could lay on the bench underneath Sara and slide that dildo fully into her cunt while Vicky fucked her asshole from behind. That really set Sara off, her body too exhausted to do anything but accept the pain. "Tell us that you're a fuck toy Sara," ordered Jane. "Ah, I'm a fuck tt...toy," said the teen, her sweat coating the crushing ropes on her skin. "Tell us that you love being a toilet," said Vicky with a vicious thrust into the girl's overstretched, bleeding asshole. "AAAooowch. Oh, shit," panted Sara, "I...I love being a toilet." Jane was approaching an orgasm from the other end of the strap-on rubbing her cunt. She slammed into the teen, twisting the nipple bars causing blood to ooze from them while Vicky held the girl's slim hips. "Tell us how much you deserve to be hurt," rasped Jane. Despite her exhaustion, somehow Sara began to feel more lust boil in her crotch. Vicky had never taken her this far before. Close, but not quite, and Sara was now delirious with pain and pleasure. "H...hurt me, please. I deserve it. I'm your pain toy, please, hurt me." Jane complied, twisting and pulling Sara's nipples while she and Sara screamed together. Sara in pain and now, lust, and Jane as she came. They let Sara hang there, her arms going numb, for a half hour. Sara really was delirious now; she'd been denied her orgasm and needed one. Pain and pleasure were the same to her. They fed her a small bottle of gatoraide, then a whole quart of water while she begged them to drink their urine and to let her cum. "Don't worry love," said Vicky as they untied the girl, " you'll get plenty of that later. But now, it's time for us to put you in the box for bed." "Uhhh... yes Mistress, the box. I deserve the box tonight. Will you hurt me more tonight? Will you use me, Mistress?" The thirteen year old barely knew what she was saying. "Yes love, you'll be in pain all night, and if you're a good girl, tomorrow we'll make you cum until you pass out. We'll make it so that your little clitty is too sore to even touch." "Tha..thank you Mistress," said Sara, slowly coming to herself as she could now take deep breaths again and the water had had time to revive her. 'The Box' was Vicky's old toy box. Her mother had told her to get rid of it because she didn't have any more toys, but Vicky had begged to keep it. She had one more toy, after all, even if her mother would have been appalled to find out what it was. Vicky and Sara had worked to modify it to hold Sara for extended periods. Sara had done most of the work, at Vicky's direction, affixing straps and mounts to hold Sara helpless and cramped throughout the night. There was even a liner so that if Sara pissed herself, or Vicky pissed on her, nothing leaked out and the teen would spend the night lying in and smelling, their piss. Because of her new piercings, tonight would be a little different. First Sara was fitted with a rubber corset. It was wide enough to go from the base of her ribs to the top of her hips. The center of the corset was about two inches smaller in diameter than the top and bottom. They drew it tight enough to make the girl wince. Then, she was placed in the box after they installed the liner and removed the wall at the foot of the box. Straps went across her belly and chest. Each leg was bent and spread, then tied to the bottom of the chest beside her waist. Her ankles were tied down at the other end and her arms were strapped to the sides. Her head was put on a small piece of foam to keep it tilted slightly towards her chest. Then, since the end that they had removed gave excellent access to her asshole, Jane leaned down a began to rim the raw hole. Shit and some blood stained it, but Jane licked it all up with relish as Vicky prepared the dildo that would spend the night in Sara's asshole. The wall at the foot of the box had a fixture that would hold the dildo in place and after Vicky finished lubing the it, she nudged Jane out of the way and began to slide the dildo into Sara. Sara groaned as she felt the head of the dildo in her asshole. She knew this one and Vicky had never been able to fit it entirely inside her. It was ten inches long and very thick. She often bled from Vicky fucking her with it, but that never stopped Vicky and it didn't stop her now. This time, despite all of Sara's crying and moaning, Vicky managed to get the entire ten inches into her sister, Sara's anal ring stretched far beyond anything Jane would have thought possible - and she'd had her asshole fisted a number of times. They slid the wall in place and attached the dildo to it's mount. Finally, Jane watched as Vicky put the new harness on Sara, bending down to listen to something Sara whispered to her before Vicky slid the tube into her mouth. "Now love, you're almost set for tonight. While you were at school today, Jane and I added a few slight modifications to your box." As she said this, she slid a metal rod into holes drilled into the top of each of the box sides. The rod was almost directly over her nipples. It actually ran through a small crank which allowed the rod to be turned, but only in one direction. There was a latch that had to be released in order to turn the rod the other way. Strong string was attached to metal hooks - two hooks for each nipple bar. The string was fed through holes in the rod. Then, wires were fed down and attached to each of the four hooks. "I'm sure", said Jane with a smirk on her face as she hooked the wires into a Tens unit, "that you'll get a charge out of this!" Vicky groaned at the pun, but Sara didn't know what the thing was. She found out soon enough as Jane began testing it. At first, there was just a pleasant, but weird feeling, a buzz in her nipples. It intensified as Jane changed the settings and wrote things down on a pad. Finally, in the last settings, Sara was screaming as loud as she could each time Jane flipped the switch. The pain in her breasts causing her to twitch uncontrollably, causing her fatigued anal sphincter to clamp helplessly on the huge intruder in her body and piss to shoot from her body. Jane switched it off, and Sara lay there, sweat pouring from her filthy body. "Now, just so you know," said Vicky as she started to turn the crank, "what your night will be like, I'm going to give you the plan." The crank continued to turn, Sara whimpering as her newly pierced tits were pulled into a cone. "Each time Jane or I have to piss, your gonna get a nice shock - sort of pre-flushing of our toilet. We're going to piss down that tube in your mouth and you, our good little toilet will swallow it. The rest of the time, the tube will be capped, so you'll need breath through your nose or around the tube. Considering how you smell, I'm sure you'll enjoy that." Sara groaned and closed her eyes, knowing that she'd also be laying in a puddle of her own piss come morning. Jane and Vicky closed the top of the box, pulling the other end of the long tube in Sara's mouth out a hole and attaching a 'female urinal' to it. They giggled about the name, considering where the urinal was draining. "Oh yeah," said Jane just before they closed the box top all the way, "Every time one of us has to piss, in addition to shocking the crap out of your tits, we're going to tighten the crank just a bit- like this." She proceeded to tighten the crank one notch further, causing Sara to squirm and try to reduce the pain in her tits. "'Night cunt," smiled Jane as darkness fell for Sara. Later, as Jane was sliding her long tongue deep into Vicky's shitter, Vicky thought back on what Sara had said before she'd put the tube in her mouth. "Mistress," she whispered when Vicky's head was close, "Do you remember your promise? You promised you'd make my clit too sore to touch, that you'd rub it raw until I couldn't feel pleasure there, only pain, for a day or so. Will you do that soon?" "Shhh. Yes honey. Remember, mommy's going away for a month this summer and summer vacation's only two weeks away. There's all kinds of things we can do. If you're a good girl, maybe we'll even pierce your clit." "Oooo, thank you Mistress." replied Sara as she opened her mouth for the wide tube. Vicky orgasmed while remembering, causing Jane to get a small mouthful of soft shit from her contractions. She orgasmed again while sharing it in a deep kiss with Jane, her sister suffering, cramped in a box only a few feet away.
