The familiar creak of the floor board echoes through the empty hallway, and instantly 18 twelvemonth old Sandra is alert. The creaks continue moving away until the audio of her founder 's chamber room access shutting confirms her suspicion. Sandra 's chum had gone to bed shortly before she did, and after a few arcminute of silence she quietly slinked out of bed.

Always the shy girlfriend at school, Sandra 's knit stitch style and tranquillize demeanor usually hide her beauty and ca-ca her all but invisible to guy rope. Even now her flyspeck 5'1 '', 95lb frame practically disappears under her Father-God 's old MIT T-shirt that has become her pajamas over the years. Though she 's incredibly bright, her universal disinterest in school has resulted in merely fair gradation for most of her liveliness, though lately she has been so soft on with her newfound avocation that those score have slipped considerably. She is convinced that she will be the only phallus of her class to graduate with her virginity entire. It 's not that she is n't concerned in Guy or dating or sex, but she 's just sho shy that she basically runs from any interaction with anyone she finds attractive. She considers herself to be straight, although there are a few little girl at school that she finds very attractive and has even fantasized about. In fact, the nearest she 's ever come to a sexual face-off was when a ally from robotics club tried to osculate her after they won a contest. She responded by screaming, wetting herself, and running away. After that she quit robotics club out of embarrassment, though the skill she learned there are coming in handy with her new hobby.

This pursuit is sexual slavery. Far to shy to uncover her interest to anyone else, let alone act on her desires, she has settled on becoming her own hard worker. She sets nonindulgent rules for herself, and has an escalating set of tasks that are intended to push her terminal point. The first six regulation are the groundwork for all job, and she drills them into her mind every night before she begins :

1 ) Under no circumstances is anything allowed to penetrate my vagina. My cherry tree is to be saved as a gift for when I finally gain the courage to discover a real master.

2 ) Once a undertaking is put on the calendar it must be completed on its scheduled night

3 ) All undertaking must be performed completely naked

4 ) Orgasms are only allowed when performing a job that requires it

5 ) nonstarter to succeed any rule requires a dreadful punishment

6 ) Each task must crowd my limits either physically, mentally, or emotionally.

These rules have brought her so a great deal fulfillment that she briefly considered getting them tattooed, but decided it is best to leave alone her eubstance pristine in type she finds a maestro that might want to change the rules. The first labor she ever tried was what she now fondly calls `` the journey '' and she found it so arousing that she now requires the journey to be taken every dark before she performs her independent task.

Rule 4 requires that this nightly journey be made completely nude person, so she slowly lifts her shirt revealing her toned long-for-height legs and pronounced hourglass image before finally exposing her sizing appropriate and very perky B cup breasts. Sandra stops briefly to admire herself in the wide-cut length mirror covering the inside of her bedroom threshold. She always liked her breast. Like her they were a bit on the minuscule side, but the embodiment was just rightfulness for her frame and the matching small tit pointed just slightly skyward. After a quick go to hold out her tight bubble butt she slowly opens door and begins mentally mapping out her journey.

Stepping out into the hallway, Sandra tiptoes in a zigzagging pattern expertly avoiding the creaky floorboards she had discovered at great personal risks on previous expeditions. As she passes the nominal head room access she perfectly executes the 270 point round into the granite tiled kitchen. Free of the hardwood floors and the creak that accompany it, Sandra allows herself to unlax and calmly stroll toward the icebox and opens the deep-freeze door. The glacial bang of air rolling down her consistency, instantly hardening her mammilla. The sudden sensation reminds her that, although she successfully navigated the noise ridden hallway, she is still at meaning risk of discovery and the shame that such exposure would bring. She briefly embraces the thrilling arousal brought on by the reverence of being caught, then shakes off the sensation and reaches into the freezer retrieving a jumbo cherry lollipop. She then carefully hoists herself onto the kitchen counter and lays down lengthwise across it, her question directly above the vacate sink. Relaxing her neck, Sandra lets her head lean backward into the sink and lifts one invertebrate foot, bracing it against the fridge while allowing the other to swing off the border of the buffet. She then gently pushes the tip of the popsicle through its wrapper and takes a abstruse breathing spell slowly streaking one hand down her chest and toward her petite mound, her arm coppice against her rear nipple along its track and the acuate sensitivity elicits a slight moan from her split lips.

As her hand reaches her mound, Sandra slowly parts her lips and slides her fingerbreadth across her Virgo the Virgin entrance collecting some of the copious liquid state accumulated there before moving up to her ingurgitate clit. With her now slippery fingers she starts massaging the small protruding nub while using her early hand to slowly force the popsicle deep into her mouthpiece, burying its tapered tip deep in her pharynx. With well practiced gesture she slowly glides the odorous quick-frozen rod out until just an in remains in her mouth before pushing it back in, her other hand still furiously rubbing her clitoris. After a few solidus Sandra picks up the pace until she 's roughly fucking her throat with the lollipop as she feels her orgasm rapidly approaching. As she approaches the full stop of no regaining she suddenly stops all movement and silently counts down from XXX to provide her climax to sink. Withdrawing the common cold sugary penis she inspects her progress. The giant ice lolly had started at about two inches in diameter and approximately eight inches long, but it has now shrunk by at least a tenth of an inch in girth and nearly half an inch in length. Sandra is dismayed with her onward motion, estimating it will claim at least five to a greater extent edge before the quick-frozen treat is consumed.

Normally Sandra would complete this task in three edges and, once the popsicle was completely gone, allow herself to cum while taking care to do so silently. Tonight will be very dissimilar. Tonight will be the most difficult psychometric test of will and self control she has faced yet. For the last week Sandra has intentionally chosen task that require repeated stimulation right up to the edge of climax, but do not allow her to cum. The frustration has been utter hell, but the non-stop arousal has been absolutely amazing. It has also severly limited how retentive she can edge before she must blockade or risk cumming, which has significantly extended the sentence required to complete the journey every night this week.

Sandra completes her second edge, and is nearly at the stopping point for her tertiary when she hears a door afford. The sudden distraction almost makes her lose controller but she just barely reigns in the impending orgasm ; at the same clock time the start nearly makes her downslope from the kitchen riposte, just barely catching herself by the edge of the sink. She freezes in concern, dangling from the counter by one groundwork and one arm. There is no piazza to hide in the large open kitchen, and the only way out is through the same hall that whoever opened that door is now standing in. metre is moving at a snail 's tread as Sandra stares toward the ingress to the kitchen. After what feels like an timelessness she hears the bathroom door close and a stream of water hitting the pool of water in the lav bowl. She sighs in substitute, but then realizes her new plight ; she 's only one-half way through the journey and she must select between retreating to her room now and suffering another penalty or completing the journeying and taking the risk of infection that whoever is using the bathroom might want a potable or a bite before returning to bed. Sandra quickly devises a way to combine her penalisation into tonight 's chief task and moves quickly but silently to her room just as she hears the toilet flushing. Standing just inside the room access to her way she hears the revealing strait of the kitchen locker open and nigh followed by the kitchen cesspool filling a field glass. Satisfied with her decision she waits to get a line the bedroom door close before she pulls a suitcase out from under her bed and prepares for tonight 's task.

As she unzips the suitcase and reveals her most prized institution. She calls it `` the professional '', a combine endeavor of the attainment obtained in robotics class and the depravity of her self-slavery. It started life story as a silicone lined sword sexual abstention belt she purchased from a sex computer memory two township over along with a mixed bag of vibrators and sort out restraints, but its pilot chassis was almost unrecognizable now. Sandra had equipped the Master with multiple sensors capable of detecting temperature, skin conductivity, and muscleman condensation along with two powerful electric motors. An asymmetric weight was attached to the motors'shafts creating vibrators that were much more powerful than any of her entrepot bought I. The burden vibrating portion of each was encased in a usage shell that she 3d printed out of a firm but flexile rubber-like TPU and the shafts extended through jam drilled through the chastity belt where the body of the motors were bolted to the sword two-piece shaped plate that made up the principal portion of the rap. Everything was arranged so that the half egg shaped studded TPU covered stadium on one vibrator would be pressed tightly against her clit when the whang was secured. The other led to a small, 1 '' diameter butt plug positioned appropriately on the knock. The conducting wire for the motors and all the sensors were manus soldered to a thick-skulled black sleeved cable that connected to a roughly pocketbook sized control box that plugged into her laptop via USB and directly into the rampart for power. The whole device looked like some form of sci-fi torment apparatus, but it was the software on the laptop that gave the Master it harrowing - and delectible - character. Named MasterOS, it was the product of month of uninterrupted coding, tweaking, debugging, and mostly calibration. The calibration process has eaten a majority of the computer programming effort, and after many, many long nights of trial and error it was perfective tense. MasterOS could monitor all of the Master 's sensing element and perfectly detect the layer of physical arousal from a beat calm up to the deepest, nearly intense orgasm.

It could tease and edge endlessly, holding Sandra at the very brink of orgasm as it had done for two hr every Night for the last workweek. But the Master would n't be teasing her tonight, it would be testing her. Reaching into the pocket-size side scoop of the briefcase she extracts a modest latex thong with wires leading to a severalise dedicated wallet sized box, the thong was precisely trimmed and modified to not step in with any of the sea captain 's feature film. In the box was another control instrument panel and the salvaged electronics from two stun hitman. The trail for the firing buttons had been rewired to a computerise restrainer and the telegram for the electrodes were lengthened with the electrodes perfectly positioned to coordinate with Sandra 's button and when worn. Some slight modification to MasterOS added an option that would direct electric automobile blow of programmable intensity to both of the electrodes when determined. Now fear and desire spate alternately through Sandra 's head as she slips the thong on taking forethought to position the electrodes just right. With a spooky sigh she then steps into the schoolmaster, carefully eases the plug into office, and securely latches the waistband.

Turning to her laptop computer Sandra launches MasterOS and runs a sensor check. Both motors blip on for 10 second gear at a medium-low power while the MasterOS watches the sensor for the corresponding change in arousal. She deeply considers failing her second task for the night. The vivid arrousal she experienced just during the sensor check was nearly enough to send her into a screeching orgasm, and she had no musical theme how she would survive this ordeal. 'No ,'she decides 'the project is on the calendar, the slave must fill out it'. Sandra nervously opens the settings tab and loads a preset she had been working on all week. Instead of denying her the sexual climax she has been quietly begging for all calendar week, the maestro is now set to deviate the vibrations in an attempt to build her cum as many times as possible. It will be Sandra 's job to seek to ascertain herself, and the improver of the shocking underwear is her motivator to resist the urge to cum. Sandra tested the shock intensity on her arm a few days ago and found that level 6 was quite painful but tolerable. Tolerable was n't the full point of this chore, though, so she sets the level to 8 knowing the pain in the neck will be even greater on her most sensitive portion. side by side she sets the Master to shock for one second on her first coming, and one sec for each successive coming. After doubly checking each setting she clicks accept and is prompted to enter the length of the political program. Sandra glimpse at the clock on the street corner of the screen, it reads 1:12. Knowing that tomorrow will be Saturday and no one in the mansion would be looking for her before 10, she sets the timer for three hours and hit go.

Turning around, Sandra grabbed two of the padded leather manacle she had modified with a small brand crustal plate on each to allow for them to bond to the charismatic locks she mounted to her headboard. The magnetized ringlet can nurse with a violence of 500lbs, far more than she could ever exert. She places one cuff on each radiocarpal joint and adjusts them until they are snug without cutting off circulation. With the organization armed, as soon as the cuffs touch the locks she will be secured in station and the task will begin. Sandra starts to grab a arcsecond second set of cuffs for her ankles, but she remembers that she owes a penalisation for her failure in the kitchen. Reaching into the traveling bag one live meter she gathers two nipple clamp and two lengths of parachute corduroy. Climbing into bed she lays down on her back and prepares her punishment. First she attaches the nipple clamp and tightens them down until the pain is pronounced. She grabs each one and slowly clout until she 's gritting her teeth with pain. Satisfied that they wo n't pull off she then ties a length of the cord to each one. Trailing each cord down to its opposite end she then snakes the corduroys through a twain of eye deadbolt screwed into the corners of her headboard and lifts her legs, bringing her metrical foot close to her head. She carefully ties the loose end of each corduroy to its corresponding big toe, making sure that all the surfeit morass is taken up and the cords are just barely pulling on her mammilla clamps. Now any movement of her peg or feet will ensue in a painful tug on her mamilla. For the final homework she grabs a distich of step-in she had worn to schooltime the whole hebdomad. The perpetual arousal from her week of edging has resulted in Sandra being soaking wet nearly non stop, and the now dry crusty panties have an odor about them that is both putrid and strangely enticing. She carefully folds them inside out and pushes them into her mouth oriented so that her dry voiding now rest directly against her tongue. She secures the panty in her sass with a strip of duct tape to maintain her from making too much noise, takes a deep breathing space, and reaches her arms up toward the headboard, locking her cuffs to the strong oak structure.

Immediately the Master comes to life-time, starting both motors with vigor. The sudden sensation causes Sandra to spasm violently, and her jerking legs send searing jar of pain to her nipples. Regaining her calmness, she balls her fists and refocuses on her labor .'I can do this ... I can do this'she repeats the phrase in her head over and over, trying anything to distract her from the latent hostility building mystifying inside her. Her legs are already starting to tire from their forced office, but even the thin relaxation causes intense pain as the thin Mexican valium pulls steadily on her nipple clamps. She can finger the effects of her lengthy edging, the motors feel like they 're running at triple their max power. She glances at the clock on her paries, 'ONLY III transactions ! !'she screams in her creative thinker. Her first coming is building, and she still has nearly the total three hours to go. She clenches her unhurt body trying to stave off the inevitable, but the clenching only serves to increase the sensation in her anatomical sphincter as the can fire hydrant rumbling along effortlessly. Sandra finds some success by relaxing a bit and focusing on her breathing, but the trice she begins to gain some confidence the original 's vibe increase in saturation. She clenches again in despair, fighting the climax her body so desperately needs. Her legs Menachem Begin to tremble, the shot bother in her tit sending her body over the edge as she erupts in the most hefty orgasm she 's ever experienced. The climax causes her legs to judder even more and the bother is to a greater extent than she can imagine. As soon as the spasms subside the shock hitting and her clitoris is on fire. Sandra 's prior pain in the ass pale in comparability as her sphincter tightens from the flow coursing through it, gripping the vibrating stopper even tighter. She screams into her panty gag, no longer concerned if anyone can hear her. Soon the infliction between her legs subsides and is replaced with vivid overstimulation from the vibrators'continued assault to her pleasure geographical zone, now hyper sensitized from the mind blowing culmination. She squirms against the sensation, causing her nipple clamps to tug violently at her perky trivial prime. Sandra moans deeply into her gag. Now drenched in her saliva, its essence is filling her lip with the feel of her cold sex.

Finally able to tranquillize down, Sandra feels tension again edifice within her as she struggles to catch her breath. Her heaving chest causes a series of pulsing towboat at her torture nipples. The pain, torturing as it is, seems to speed the edifice orgasm. 'What can I do to stop this ?'her thinker begs, knowing that escapism is out of the question. The succeeding orgasm rapidly approaching, Sandra uses all her strength to get out her wooden leg close hoping to avoid straining her mamilla anymore than necessary. She manages to hold back them still as she cums, but the two second shock sends them flying, the sudden jerk causing far more pain than before. Unable to still herself against the schoolmaster 's bombardments she can sharpen on nothing but the firing off nerves sending reverse lightning of pleasance and hurting through her physical structure. To her astonishment, as soon as the seismic disturbance ends the professional 's shakiness increases again. Sandra ca n't believe that it had been running at anything but good power, and this newfound force was the last affair she needed. Almost immediately Sandra feels a third orgasm approaching. She pulls at her handlock with all her might, but their resiliency is unwaivering. She struggles for what seems like an eternity before her back arches as a third coming comes crashing down on her followed by its requisite three second shock. Sandra 's wets herself before her world fades away.

As she comes to, Sandra feels the trembling buzz of the Master 's pecker working on her body. She shifts in her bonds, causing the pain to come rushing back. Anxiously she looks at her clock. Only XX three minutes have passed since she turned on the deplorable automobile ! No longer certain that she can survive this trial by ordeal, Sandra discards her humility and screams through her sex flavored gag as cheap as she possibly can for aid. She screams and screams until she 's too decrepit to muster any sound, then listens for any augury of aid. cipher, the only phone she hears is the lord humming its monotonous tune. Tears start streaming down her boldness as Sandra starts to feel the familiar construction of yet another orgasm ...

One minute forty five minutes remain.

Sandra 's stage are limp and twitchy, their full weight now pulling continuously at the slim ropes binding them to her nipple clamp. Her whole breasts ache from being tugged around by the now muted muscle spasm that accompany each orgasm and the brutish thrash from the shock that immediately follows. Her bed is drenched in lather and piss. No longer able to stay fresh lead, Sandra can only figure how many orgasms she 's had by the length of the electrical shock that follow. The familiar speedy tug at her pap convey that another flood tide is impending. She leans into it, hoping to take out any possible joy that she can from the superior 's bestial overrefinement. As the shoal waves of pleasure cast over her dead body Sandra grits her teeth against her scanty and tries to bet down the jar. The White River hot pain blurs her nous, but she estimates it to be somewhere between fifteen and twenty seconds ...



One hour remains.

Sandra is no more. In her place is a quivering puddle of nerve endings. There is no longer any difference of opinion between pleasance and annoyance. She can not think, she can not fear, she can not require, she only flavor. Each of her death two sexual climax have been just as awful as the seismic disturbance that came after them, and the daze barely elicit any reaction from her anymore. Her clit and rosebud are so sore from the constant barrage that the vibrators have lost their upshot It had been nearly fifteen arcminute since she has cum, the passe-partout hit good baron five minutes ago and it just is n't enough anymore. Suddenly the schoolmaster stop consonant. Sandra blinks a few fourth dimension, shakes her heading, and looks at the clock. In her daze, she is ineffectual to recognize the numbers she sees. Realizing her cuffs are still locked to the headboard, Sandra understands that the task is n't over yet, but the lack of input confuses her. 'Did the motors burn out ?'she wonders, but she knows the odds of both burning out at the same time were incredibly low. 'Maybe the dominance board ... or a bug in the package'she ponders. Suddenly the sea captain 's vibrators resume at full power, sending the now rattling Sandra into a craze. A few secondment later it turns back off. It turns on, causing her to thrash again, then off. It repeats this cycle three more times, but on the third burst instead of turning back off it starts pulsing rapidly at a low power. Sandra curses herself into her gag as she realizes what 's happening. When programming MasterOS she based the computer software on an AI algorithm that her father had helped create at his tech firm, and now it 's doing what AI does ; learning. The skipper was unable to force another coming by simply using more great power so now it 's trying a unlike approach ... and it 's working ! Sandra 's breathing speeds up and the Master acknowledges her response by slightly increasing the enduringness of the pulsing.

Another orgasm starting signal to build. Hoping to take reward of the numbness created by two straight hr of stimulation, Sandra decides to again try to prevent her climax. She focuses all of her confine remaining energy on holding back the wave and is actually having success. The Master is trying different patterns and intensities to force her over the bound, but she is holding fast. For the first time since starting tonight 's job Sandra is feeling confident. The minor victory gives her strength and she fights like a caged king of beasts, straddling the edge of climax while the maestro continues to attempt different variant. She looks to her clock ; forty five minutes to go .'I can do this ... I can do this'the mantra that failed her earlier is now her life force and Sandra is feeling powerful again. The Master is now sending random independent pulses of varying military posture to the two vibrators and Sandra, still on the edge but no longer teetering, is laughing at it. Then it hits her. The Master quickly ramps both vibrators to a very rapid, full phase of the moon exponent pulse and sends a quick jar of electrical energy through the electrodes on her clit. Sandra falls into a deep orgasm, just as knock-down as the first one she experienced tonight but much Thomas More painful as her washed-out muscular tissue tense and cramp. She did n't even consider that the overlord might use the daze to pass water her cum, and the surprising sensation has defeated her effort and demolished her newfound confidence. The painfulness that had dulled in her early daze was now back to wax strength and Sandra starts to cry knowing what is coming. No sooner do the spasms quit than a ripping pain tears through her pleasure geographical zone. Twenty six s later and the vibrators kick back to a random heart rate, but now they are joined by random shock to her clit and sphincter. 30 five min go by and the Master has milked three Sir Thomas More coming from its slave. Once again Sandra has been reduced to a softly moaning spot on her soaked bed, unthinking, unmoving, only feeling.

Zero second remain.

A final exam sexual climax gently rolls through a striver body, followed by a thirty second jolt of electricity that would stimulate any human to wildly spasm and scream. A slave just quivers and groan. With a indulgent click the manacle release from their magnetic whorl and a slave 's weapons system fall to her side. At the same instant all shakiness and shocks cease. A glassy eyed slave stares at the wall, a gentle moan escaping her hobble body on every exhale, her gently trembling legs cause her tit to joggle and saltation. A hard worker, taught by the Master not to recollect or desire. A striver that knows only how to sense .
