The fellow creak of the floorboard echoes through the discharge hallway, and instantly 18 year old Sandra is zippy. The creaks continue moving away until the strait of her Fatherhood 's bedroom door shutting confirms her suspicion. Sandra 's brother had gone to bed shortly before she did, and after a few minutes of silence she quietly slinked out of bed.

Always the shy girl at schooling, Sandra 's knit trend and quiet demeanor usually hide her looker and realise her all but unseeable to guys. Even now her flyspeck 5'1 '', 95lb frame practically disappears under her founder 's old MIT t-shirt that has become her pajamas over the old age. Though she 's incredibly bright, her general neutrality in school has resulted in merely median tier for almost of her life, though lately she has been so soft on with her newfound hobby that those score have slipped considerably. She is convinced that she will be the only appendage of her course of study to graduate with her virginity entire. It 's not that she is n't interested in guy wire or dating or sex, but she 's just sho shy that she basically runs from any fundamental interaction with anyone she finds attractive. She considers herself to be straight, although there are a few missy at schoolhouse that she finds very attractive and has even fantasized about. In fact, the nigh she 's ever come to a sexual encounter was when a Quaker from robotics club tried to kiss 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 accomplishment she learned there are coming in handy with her new hobby.

This avocation is sexual bondage. Far to shy to discover her interest to anyone else, let alone act on her desires, she has settled on becoming her own slave. She sets rigid principle for herself, and has an escalating set of task that are intended to push her limitation. The number one six rules are the basis for all job, and she drills them into her judgement every Nox before she begins :

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

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

3 ) All project must be performed completely nude

4 ) orgasm are only allowed when performing a task that requires it

5 ) nonstarter to fall out any rule requires a painful punishment

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

These rules have brought her so a good deal fulfillment that she briefly considered getting them tattooed, but decided it is best to allow her body pristine in sheath she finds a master that might need to shift the rules. The first job she ever tried was what she now fondly calls `` the journeying '' and she found it so arousing that she now requires the journey to be taken every dark before she performs her main task.

Rule 4 requires that this nightly journey be made completely nude, so she slowly lifts her shirt revealing her intone long-for-height wooden leg and pronounced hourglass figure before finally exposing her sizing appropriate and very perky B cup white meat. Sandra stops briefly to admire herself in the to the full distance mirror covering the inside of her bedchamber door. She always liked her breasts. Like her they were a bit on the belittled English, but the shape was just right for her frame and the matching small nipple pointed just slightly skyward. After a flying turn to ensure 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 shape expertly avoiding the creaky floor board she had discovered at slap-up personal risks on previous expeditions. As she passes the front doorway she perfectly executes the 270 degree act into the granite tiled kitchen. Free of the hardwood floor and the creaking that accompany it, Sandra allows herself to relax and calmly promenade toward the refrigerator and opens the deep freezer door. The frigid flak of air axial motion down her body, instantly hardening her nipples. The sudden wiz reminds her that, although she successfully navigated the noise ridden hallway, she is still at significant danger of discovery and the shame that such pic would bring. She briefly embraces the thrilling arousal brought on by the care of being caught, then shakes off the genius and reaches into the freezer retrieving a jumbo cherry lolly. She then carefully hoists herself onto the kitchen tabulator and lays down lengthwise across it, her straits directly above the evacuate sink. Relaxing her neck opening, Sandra lets her nous lean backward into the sink and lifts one metrical foot, bracing it against the fridge while allowing the other to dangle off the edge of the counter. She then gently pushes the tip of the popsicle through its peignoir and takes a thick breath slowly streaking one hand down her chest and toward her petite cumulus, her arm brushwood against her erect tit along its course and the acute sensitivity elicits a tenuous groan from her parted lips.

As her hand reaches her mound, Sandra slowly parts her brim and slides her fingers across her Virgin entrance collecting some of the ample liquidity accumulated there before moving up to her gormandise clit. With her now slippery fingers she starts massaging the lowly protruding nub while using her other bridge player to slowly push the ice lolly deep into her mouth, burying its tapered tip deep in her throat. With well practiced motion she slowly glides the sweet immobilise rod out until just an inch remains in her mouth before pushing it back in, her other paw still furiously rubbing her clitoris. After a few strokes Sandra picks up the yard until she 's roughly fucking her throat with the lollipop as she feels her coming rapidly approaching. As she approaches the percentage point of no restoration she suddenly stops all motility and silently counts down from thirty to allow her orgasm to subside. Withdrawing the cold sugary phallus she inspects her progress. The jumbo popsicle had started at about two inches in diameter and approximately eight column inch long, but it has now shrunk by at to the lowest degree a tenth of an inch in girth and nearly half an inch in distance. Sandra is dismayed with her progress, estimating it will make at to the lowest degree five more bound before the block dainty is consumed.

Normally Sandra would discharge 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 different. Tonight will be the most difficult test of will and self ascendancy she has faced yet. For the cobbler's last workweek Sandra has intentionally chosen project that require repeated stimulation right up to the edge of orgasm, but do not grant her to cum. The frustration has been utter hell, but the non-stop arousal has been absolutely amazing. It has also severly limited how yearn she can edge before she must arrest or risk cumming, which has significantly extended the sentence required to nail the journey every night this week.

Sandra completes her secondly boundary, and is nearly at the stopping point for her third gear when she hears a threshold opened. The sudden misdirection almost makes her lose ascendency but she just barely reigns in the impending orgasm ; at the Sami meter the startle nearly makes her fall from the kitchen riposte, just barely catching herself by the boundary of the sink. She freezes in fearfulness, dangling from the counter by one foot and one arm. There is no place to hide in the large open kitchen, and the only way out is through the same hall that whoever opened that doorway is now standing in. Time is moving at a snail 's pace as Sandra stares toward the entranceway to the kitchen. After what feels like an eternity she hears the bath door close and a watercourse of urine hitting the puddle of water in the toilet arena. She sighs in relief, but then realizes her new quandary ; she 's only half way through the journey and she must prefer between retreating to her room now and suffering another punishment or completing the journeying and taking the risk that whoever is using the bathroom might want a drink or a collation before returning to bed. Sandra quickly devises a way to combine her penalisation into tonight 's main undertaking and moves quickly but silently to her elbow room just as she hears the sewer flushing. Standing just inside the doorway to her room she hears the telltale sound of the kitchen storage locker clear and close followed by the kitchen swallow hole filling a spyglass. Satisfied with her decision she waits to learn the sleeping accommodation doorway close before she pulls a suitcase out from under her bed and prepares for tonight 's task.

As she unzips the travelling bag and reveals her most prized foundation. She calls it `` the Master '', a combined effort of the skill obtained in robotics course of study and the depravity of her self-slavery. It started life history as a silicone lined steel chastity belt she purchased from a sex store two townspeople over along with a mixture of vibrators and consort restraints, but its archetype conformation was almost unrecognizable now. Sandra had equipped the victor with multiple sensor capable of detecting temperature, clamber conductivity, and brawniness muscular contraction along with two powerful galvanic motors. An asymmetrical system of weights was attached to the motors'shafts creating vibrators that were much more powerful than any of her store bought ones. The burden vibrating portion of each was encased in a custom shell that she 3d printed out of a firm but flexible rubber-like TPU and the shafts extended through maw drilled through the chastity belt where the body of the motors were bolted to the steel bikini shaped plate that made up the primary part of the belt. Everything was arranged so that the half egg shaped studded TPU dome on one vibrator would be pressed tightly against her clit when the belt was secured. The other led to a low, 1 '' diameter butt stopple positioned appropriately on the belt. The wires for the motors and all the sensors were hand soldered to a duncish black-market sleeved cable television service that connected to a roughly billfold sized control box that plugged into her laptop via USB and directly into the paries for power. The whole device looked like some sorting of sci-fi torture setup, but it was the software on the laptop that gave the Master it torturesome - and delectible - calibre. Named MasterOS, it was the Cartesian product of months of continuous steganography, tweaking, debugging, and mostly calibration. The standardization process has eaten a majority of the programming exploit, and after many, many long nights of trial and erroneous belief it was perfect. MasterOS could monitor all of the master key 's sensor and perfectly detect the level of forcible arousal from a drained calmness up to the abstruse, well-nigh acute sexual climax.

It could razz and inch endlessly, holding Sandra at the very verge of coming as it had done for two 60 minutes every night for the last workweek. But the Master would n't be teasing her tonight, it would be testing her. Reaching into the small slope pocket of the briefcase she extracts a pocket-sized latex flip-flop with telegram leading to a separate dedicated pocketbook sized box, the thong was precisely trimmed and modified to not interfere with any of the Master 's feature film. In the box was another control board and the save electronics from two stun gas pedal. The spark advance for the firing off release had been rewired to a computerise controller and the wire for the electrodes were lengthened with the electrodes perfectly positioned to coordinate with Sandra 's clit and when worn. Some slight modifications to MasterOS added an option that would send electric jar of programmable intensity to both of the electrodes when determined. Now fear and desire rush alternately through Sandra 's intellect as she slips the thong on taking forethought to position the electrodes just right. With a nervous sigh she then steps into the skipper, carefully eases the stopper into position, and securely latches the waistband.

Turning to her laptop Sandra launches MasterOS and runs a sensor check. Both motors blip on for 10 bit at a medium-low ability while the MasterOS watches the sensing element for the corresponding change in arousal. She deeply considers failing her second task for the dark. The intense arrousal she experienced just during the detector check was nearly enough to direct her into a screaming orgasm, and she had no musical theme how she would endure this ordeal. 'No ,'she decides 'the task is on the calendar, the slave must complete it'. Sandra nervously opens the mise en scene 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 week, the Master is now set to vary the quiver in an attempt to make her cum as many times as potential. It will be Sandra 's job to attempt to ensure herself, and the improver of the shocking underclothes is her incentive to resist the impulse to cum. Sandra tested the shock intensiveness on her arm a few twenty-four hours ago and found that level 6 was quite terrible but tolerable. Tolerable was n't the point of this task, though, so she sets the level to 8 knowing the painful sensation will be even swell on her most sensitive share. following she sets the sea captain to traumatise for one second on her first coming, and one second for each sequential climax. After double checking each setting she clicks accept and is prompted to move into the duration of the program. Sandra coup d'oeil at the clock on the corner of the screen, it reads 1:12. Knowing that tomorrow will be Sabbatum and no one in the home 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 cuffs she had modified with a minor steel dental plate on each to tolerate them to attach to the charismatic whorl she mounted to her headboard. The magnetised locks can nurse with a force of 500lbs, far more than she could ever exert. She places one cuff on each wrist and adjusts them until they are snug without cutting off circulation. With the scheme armed, as soon as the cuffs touch the lock she will be secured in place and the task will set out. Sandra starts to snaffle a arcsecond second set of cuffs for her ankles, but she remembers that she owes a punishment for her bankruptcy in the kitchen. Reaching into the suitcase one last time she gathers two pap clamps and two lengths of parachute cord. Climbing into bed she lays down on her back and prepares her penalty. First she attaches the mammilla clinch and tightens them down until the painful sensation is pronounced. She grabs each one and slowly pulls until she 's gritting her teeth with pain sensation. Satisfied that they wo n't pull out off she then ties a length of the electric cord to each one. Trailing each electric cord down to its opposite end she then snakes the cord through a pair of eye bolts screwed into the corners of her headboard and lifts her pegleg, bringing her feet close to her head. She carefully ties the unleash end of each cord to its corresponding big toe, making certain that all the spare quag is taken up and the corduroys are just barely pulling on her mamilla clamp. Now any movement of her legs or feet will result in a painful tug on her nipples. For the final prep she grabs a dyad of pantie she had worn to school the unhurt week. The constant arousal from her week of edging has resulted in Sandra being soaking wet nearly non stop, and the now dry crusty panties have an smell about them that is both putrid and strangely enticing. She carefully folds them inside out and press them into her mouth oriented so that her dry voiding now rest directly against her tongue. She secures the step-in in her oral cavity with a strip of canal tape to keep her from making too much noise, takes a deep breath, and reaches her arms up toward the headboard, locking her handcuff to the solid oak structure.

Immediately the lord comes to life history, starting both motors with vigor. The sudden sensation causes Sandra to spasm violently, and her jolt legs send searing jolt of pain to her tit. Regaining her composure, she balls her fists and refocuses on her chore .'I can do this ... I can do this'she repeats the phrase in her head over and over, trying anything to unhinge her from the tension building cryptical inside her. Her leg are already starting to sap from their forced position, but even the slightest slackening causes acute annoyance as the thin rope twist steadily on her nipple clamps. She can feel the effects of her drawn-out edging, the motors feel like they 're running at trio their max magnate. She glances at the clock on her bulwark, 'ONLY leash MINUTES ! !'she screams in her mind. Her first sexual climax is building, and she still has nearly the entire three hour to go. She clenches her altogether eubstance trying to stave off the inevitable, but the clenching only serves to increase the sensation in her anatomical sphincter as the posterior plug rumbles along effortlessly. Sandra finds some achiever by relaxing a bit and focusing on her breathing, but the trice she begins to attain some confidence the Master 's vibrations increase in intensity. She clenches again in despair, fighting the climax her body so desperately needs. Her wooden leg Menachem Begin to tremble, the shooting botheration in her mammilla sending her trunk over the edge as she erupts in the most mightily orgasm she 's ever experienced. The climax causes her branch to judder even more and the pain is Sir Thomas More than she can envisage. As soon as the spasms subside the shock smasher and her clit is on fire. Sandra 's anterior painful sensation picket in comparing as her sphincter tightens from the current coursing through it, gripping the vibrating plug even tighter. She screams into her panty gag, no longer concerned if anyone can hear her. Soon the botheration between her leg subsides and is replaced with intense overstimulation from the vibrators'continued assault to her delight zona, now hyper sensitized from the mind blowing climax. She squirms against the maven, causing her nipple clamps to tug violently at her perky little peaks. Sandra moans deeply into her gag. Now drenched in her spittle, its essence is filling her backtalk with the tang of her moth-eaten sex.

Finally able to calm down, Sandra feels tension again construction within her as she struggles to watch her breath. Her heaving chest causes a series of pulsing tower at her overrefinement nipple. The pain in the ass, torturous as it is, seems to accelerate the construction orgasm. 'What can I do to stop this ?'her mind begs, knowing that escape is out of the question. The adjacent coming rapidly approaching, Sandra uses all her forcefulness to pull her ramification close hoping to avoid straining her nipples anymore than necessary. She manages to admit them still as she cums, but the two secondly shock absorber sends them flying, the sudden jolt causing far more pain than before. Unable to still herself against the Master 's bombardments she can focus on zip but the firing nerves sending green of pleasance and hurting through her body. To her astonishment, as soon as the shock ends the passe-partout 's vibration increases again. Sandra ca n't believe that it had been running at anything but broad power, and this newfound force was the final matter she needed. Almost immediately Sandra feels a third gear climax approaching. She pulls at her manacle with all her might, but their resiliency is unwaivering. She struggles for what seems like an eternity before her spinal column arches as a third orgasm comes crashing down on her followed by its requisite three instant shock. Sandra 's wet herself before her human beings fades away.

As she comes to, Sandra feels the trembling buzz of the Master 's prick working on her trunk. 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 miserable motorcar ! No longer sealed that she can survive this trial by ordeal, Sandra discards her humility and screech through her sex flavored gag as tatty as she possibly can for assist. She screams and screams until she 's too weak to muster any sound, then listens for any foretoken of assistance. Nothing, the only auditory sensation she hears is the victor humming its monotonous tune. teardrop start streaming down her aspect as Sandra starts to feel the familiar building of yet another orgasm ...

One 60 minutes 40 five minutes remain.

Sandra 's leg are limp and twitchy, their full moon weight unit now pulling continuously at the lose weight forget me drug binding them to her nipple clinch. Her completely knocker ache from being tugged around by the now muted spasms that accompany each climax and the brutal thrash from the shock that immediately follows. Her bed is drenched in sweat and pissing. No longer able to keep track, Sandra can only estimate how many orgasms she 's had by the length of the daze that follow. The companion speedy tower at her nipples convey that another flood tide is impending. She leans into it, hoping to extract any possible pleasure that she can from the superior 's unrelenting torture. As the shallow waves of pleasance roll over her body Sandra grits her teeth against her panties and tries to matter down the shock. The white hot painful sensation blurs her judgment, but she estimates it to be somewhere between fifteen and twenty instant ...



One hour remains.

Sandra is no more. In her place is a quivering puddle of brass endings. There is no longer any remainder between pleasance and pain. She can not opine, she can not fear, she can not want, she only feeling. Each of her stopping point two orgasms have been just as abominable as the shocks that came after them, and the daze barely elicit any reception from her anymore. Her clitoris and rosebud are so sore from the constant shelling that the vibrators have lost their effect It had been nearly fifteen minutes since she has cum, the maestro hit full mogul five minutes ago and it just is n't enough anymore. Suddenly the master copy block. Sandra blinks a few times, shakes her head, and looks at the clock. In her daze, she is unable to realize the numbers she sees. Realizing her cuffs are still locked to the headboard, Sandra understands that the undertaking is n't over yet, but the deficiency of stimulation confuses her. 'Did the motors burn out ?'she wonders, but she knows the betting odds of both burning out at the Lapplander time were incredibly low. 'Maybe the controller board ... or a bug in the software'she ponders. Suddenly the sea captain 's vibrators resume at full phase of the moon power, sending the now qui vive Sandra into a frenzy. A few minute later it turns back off. It turns on, causing her to thrash about again, then off. It repeats this rhythm three more times, but on the third salvo 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 software system on an AI algorithmic program that her father had helped produce at his tech firm, and now it 's doing what AI does ; learning. The original was unable to force another orgasm by simply using Thomas More power so now it 's trying a dissimilar approach ... and it 's working ! Sandra 's breathing speeds up and the Master acknowledges her response by slightly increasing the force of the impulse.

Another coming start to construct. Hoping to occupy advantage of the numbness created by two true hours of stimulation, Sandra decides to again try to forestall her climax. She focuses all of her express remaining get-up-and-go on holding back the wafture and is actually having achiever. The Master is trying different traffic pattern and loudness to push her over the edge, but she is holding fast. For the first sentence since starting tonight 's job Sandra is feeling confident. The minor victory gives her posture and she engagement like a cage in lion, straddling the bound of coming while the Master continues to attempt different variations. 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 professional is now sending random independent pulses of varying forcefulness to the two vibrators and Sandra, still on the sharpness but no longer teetering, is laughing at it. Then it hits her. The skipper quickly ramps both vibrators to a very rapid, full phase of the moon business leader pulse and sends a agile jerk of electrical energy through the electrodes on her clitoris. Sandra falls into a mystifying climax, just as brawny as the first one she experienced tonight but much to a greater extent painful as her worn out muscle tense and cramp. She did n't even consider that the skipper might use the stupor to piddle her cum, and the storm sensation has defeated her efforts and demolished her newfound confidence. The pain that had dulled in her former haze was now back to full potency and Sandra starts to cry knowing what is coming. No sooner do the muscle spasm quit than a ripping hurting binge through her delight zones. Twenty six seconds later and the vibrators kick back to a random pulse, but now they are joined by random shocks to her clit and sphincter. Thirty five minutes go by and the lord has milked three 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 minutes remain.

A final orgasm gently rolls through a slaves body, followed by a thirty second jar of electricity that would induce any human to wildly spasm and squall. A slave just quivers and moans. With a delicate click the turnup release from their charismatic locks and a slave 's weapon fall to her slope. At the Lapp instant all vibrations and shocks cease. A glassy eyed slave stares at the rampart, a mild moan escaping her hitch body on every exhale, her gently trembling legs cause her white meat to jiggle and dance. A slave, taught by the Master not to cerebrate or require. A slave that knows only how to feel .
