The familiar creaking of the floorboards echoes through the empty hallway, and instantly 18 year old Sandra is alert. The creaking continue moving away until the auditory sensation of her father 's bedroom doorway shutting confirms her suspicion. Sandra 's sidekick had gone to bed shortly before she did, and after a few transactions of silence she quietly slinked out of bed.

Always the shy girl at shoal, Sandra 's plain style and smooth demeanor usually hide her beauty and make her all but unseeable to guys. Even now her lilliputian 5'1 '', 95lb framing practically disappears under her sire 's old MIT t-shirt that has become her pajama over the long time. Though she 's incredibly bright, her general disinterest in school has resulted in merely average grad for almost of her life, though lately she has been so infatuated with her newfound hobby that those grades have slipped considerably. She is convinced that she will be the entirely member of her family to graduate with her virginity intact. It 's not that she is n't concern in guys 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 girls at school that she finds very attractive and has even fantasized about. In fact, the closest she 's ever come to a sexual encounter was when a Quaker 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 plethora, though the skills she learned there are coming in Handy with her new hobby.

This hobby is intimate slaveholding. Far to shy to reveal her interestingness to anyone else, let alone act on her desires, she has settled on becoming her own slave. She sets strict rule for herself, and has an escalating set of tasks that are intended to push her limits. The first six pattern are the basis for all chore, and she drills them into her head every Night before she begins :

1 ) Under no context is anything allowed to come home my vagina. My cherry is to be saved as a natural endowment for when I finally gain the courageousness to encounter a real master.

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

3 ) All labor must be performed completely nude

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

5 ) nonstarter to follow any ruler requires a painful penalisation

6 ) Each project must push my terminus ad quem either physically, mentally, or emotionally.

These normal have brought her so much fulfillment that she briefly considered getting them tattooed, but decided it is best to allow for her trunk pristine in case she finds a headmaster that might require to change the rules. The first base task 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 night before she performs her briny task.

prescript 4 requires that this nightly journey be made completely nude, so she slowly lifts her shirt revealing her toned long-for-height peg and sound out hourglass figure before finally exposing her size of it appropriate and very chirpy B cup breast. Sandra stops briefly to admire herself in the full length mirror covering the inside of her bedroom room access. She always liked her white meat. Like her they were a bit on the modest side, but the shape was just right for her frame and the matching small nipples pointed just slightly skyward. After a quick turn to check out her tight babble tush she slowly opens doorway 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 excursion. As she passes the front door she perfectly executes the 270 degree turn into the granite tiled kitchen. Free of the hardwood floor and the creak that accompany it, Sandra allows herself to slack up and calmly strolls toward the refrigerator and opens the freezer doorway. The frigid blast of air rolling wave down her body, instantly hardening her teat. The sudden wizard reminds her that, although she successfully navigated the noise ridden hallway, she is still at substantial risk of find and the shame that such photo would lend. She briefly embraces the thrilling rousing brought on by the fear of being caught, then shakes off the sensation and reaches into the freezer retrieving a jumbo cherry popsicle. She then carefully hoists herself onto the kitchen counter and lays down lengthwise across it, her head directly above the empty sinkhole. Relaxing her neck, Sandra lets her headland list backward into the sink and lifts one foot, bracing it against the fridge while allowing the other to dangle off the edge of the return. She then gently pushes the tip of the popsicle through its wrapping and takes a deep breath slowly streaking one hand down her chest and toward her petite mound, her arm brushes against her erect pap along its course and the incisive sensitivity elicits a svelte moan 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 sizeable liquid accumulated there before moving up to her engorged button. With her now slippery fingers she starts massaging the small protruding nub while using her other hand to slowly crusade the lolly deep into her mouth, burying its tapering tip deep in her pharynx. With well practiced motion she slowly glides the sweetness wintry rod out until just an inch remains in her mouth before pushing it back in, her early hand still furiously rubbing her clit. After a few virgule Sandra picks up the pace until she 's roughly fucking her throat with the popsicle as she feels her orgasm rapidly approaching. As she approaches the gunpoint of no return she suddenly stops all movement and silently counts down from thirty to admit her coming to lessen. Withdrawing the cold sugary Phallus she inspects her onward motion. The jumbo popsicle had started at about two in in diam and approximately eight in 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 progress, estimating it will take at to the lowest degree five More sharpness before the frozen goody is consumed.

Normally Sandra would complete this labor in three edges and, once the lollipop was completely gone, allow herself to cum while taking precaution to do so silently. Tonight will be very different. Tonight will be the most difficult test of will and self ascendance she has faced yet. For the in conclusion week Sandra has intentionally chosen project that require repeated stimulation right up to the edge of orgasm, but do not allow her to cum. The defeat has been utter hell, but the non-stop arousal has been absolutely amazing. It has also severly limited how long she can butt before she must stop or risk cumming, which has significantly extended the meter required to complete the journey every dark this week.

Sandra completes her second edge, and is nearly at the stopping point for her third gear when she hears a door open. The sudden distraction almost makes her misplace ascendance but she just barely reigns in the impend orgasm ; at the same time the startle nearly makes her Fall from the kitchen counterpunch, just barely catching herself by the edge of the swallow hole. She freezes in fear, dangling from the rejoinder by one foot and one arm. There is no berth to hide in the large spread out kitchen, and the only way out is through the same hallway that whoever opened that door is now standing in. metre is moving at a snail 's pace as Sandra stares toward the introduction to the kitchen. After what feels like an timelessness she hears the lav door close and a current of urine hitting the syndicate of water in the toilet bowl. She sighs in fill-in, but then realizes her new predicament ; she 's only half way through the journey and she must choose between retreating to her room now and suffering another penalization or completing the journey and taking the risk that whoever is using the bathroom might need a drunkenness or a collation before returning to bed. Sandra quickly devises a way to combine her penalization into tonight 's main job and motility quickly but silently to her elbow room just as she hears the bathroom flushing. Standing just inside the door to her room she hears the telltale sound of the kitchen cabinet unfastened and airless followed by the kitchen sink filling a glass. Satisfied with her decision she waits to hear the bedroom threshold finis before she pulls a bag out from under her bed and prepares for tonight 's task.

As she unzips the suitcase and reveals her most prized creation. She calls it `` the headmaster '', a combined sweat of the skills obtained in robotics class and the depravity of her self-slavery. It started life history as a silicone lined brand chastity belt she purchased from a sex store two towns over along with a salmagundi of vibrators and consort restraints, but its original strain was almost unrecognizable now. Sandra had equipped the Master with multiple detector equal to of detecting temperature, skin conductivity, and musculus contraction along with two powerful electric car motors. An asymmetric weight was attached to the motors'shafts creating vibrators that were much more brawny than any of her store bought single. The weighted vibrating constituent of each was encased in a usage racing shell that she 3d printed out of a firm but flexile rubber-like TPU and the slam extended through holes drilled through the celibacy whang where the physical structure of the motors were bolted to the steel two-piece shaped plate that made up the principal serving of the bash. Everything was arranged so that the half egg shaped studded TPU dome on one vibrator would be pressed tightly against her clit when the bang was secured. The other led to a belittled, 1 '' diameter butt plug positioned appropriately on the belt. The wires for the motors and all the sensing element were hand soldered to a thick-skulled melanize sleeved cablegram that connected to a roughly billfold sized control box that plugged into her laptop via USB and directly into the wall for power. The altogether device looked like some form of sci-fi torture setup, but it was the software on the laptop that gave the passe-partout it harrowing - and delectible - timbre. Named MasterOS, it was the mathematical product of months of continuous cryptography, tweaking, debugging, and mostly calibration. The calibration physical process has eaten a legal age of the programming effort, and after many, many retentive nights of trial and error it was complete. MasterOS could supervise all of the Master 's sensor and perfectly detect the level of physical arousal from a dead calm up to the cryptical, virtually vivid orgasm.

It could tease and border endlessly, holding Sandra at the very brink of orgasm as it had done for two time of day every night for the last hebdomad. But the Master would n't be teasing her tonight, it would be testing her. Reaching into the humble face scoop of the briefcase she extracts a small latex thong with wires leading to a single out dedicated wallet sized box, the lash was precisely trimmed and modified to not step in with any of the schoolmaster 's characteristic. In the box was another control control panel and the salvaged electronics from two stun gas pedal. The leads for the firing push had been rewired to a computerized comptroller and the conducting wire for the electrodes were lengthened with the electrodes perfectly positioned to adjust with Sandra 's clit and when worn. Some slight change to MasterOS added an option that would send electric car electric shock of programmable intensiveness to both of the electrodes when determined. Now fear and desire kick alternately through Sandra 's mind as she slips the thong on taking caution to billet the electrodes just right. With a nervous sigh she then steps into the master copy, carefully eases the plug into post, and securely latches the waistband.

turn to her laptop Sandra launches MasterOS and runs a sensor arrest. Both motors blip on for 10 seconds at a medium-low power while the MasterOS watches the sensor for the correspond change in arousal. She deeply considers failing her second task for the Nox. The intense arrousal she experienced just during the detector curb was nearly enough to send her into a shriek orgasm, and she had no idea how she would suffer this ordeal. 'No ,'she decides 'the task is on the calendar, the hard worker must nail it'. Sandra nervously opens the stage setting tab and loads a preset she had been working on all week. Instead of denying her the orgasms she has been quietly begging for all week, the lord is now set to vary the vibrations in an attempt to make her cum as many times as possible. It will be Sandra 's job to attempt to command herself, and the summation of the shocking underwear is her motivator to dissent the urge to cum. Sandra tested the daze saturation on her arm a few days ago and found that storey 6 was quite atrocious but adequate. Tolerable was n't the point of this chore, though, so she sets the level to 8 knowing the pain will be even greater on her most medium parts. side by side she sets the Master to appall for one endorsement on her initiatory coming, and one mo for each successive climax. After double checking each setting she clicks accept and is prompted to enter the continuance 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 Sat and no one in the house would be looking for her before 10, she sets the timekeeper for three hours and hit go.

turn around, Sandra grabbed two of the padded leather cuffs she had modified with a small steel photographic plate on each to admit them to attach to the magnetised ringlet she mounted to her headboard. The magnetized curl can withstand with a forcefulness of 500lbs, far Thomas More than she could ever exert. She places one manacle on each radiocarpal joint and adjusts them until they are close-fitting without cutting off circulation. With the organization armed, as soon as the cuffs touch the ignition lock she will be secured in seat and the task will begin. Sandra starts to grab a second second set of handlock for her ankles, but she remembers that she owes a penalty for her loser in the kitchen. Reaching into the bag one lastly sentence she gathers two nipple clinch and two length of chute electric cord. Climbing into bed she lays down on her back and prepares her punishment. First she attaches the teat clamp and tightens them down until the nuisance is pronounced. She grabs each one and slowly drag 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 cords through a distich of eye bolts screwed into the corners of her headboard and lifts her legs, bringing her feet close to her head. She carefully ties the loose end of each cord to its corresponding big toe, making trusted that all the spare slackness is taken up and the electric cord are just barely pulling on her mammilla clamps. Now any motility of her legs or feet will result in a abominable tug on her nipples. For the final preparation she grabs a dyad of panties she had worn to school day the whole calendar week. The constant arousal from her hebdomad of edging has resulted in Sandra being soaking wet nearly non stopover, 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 fight them into her mouth oriented so that her dry voiding now rest directly against her tongue. She secures the panty in her mouth with a strip of duct taping to keep open her from making too much noise, takes a oceanic abyss breath, and reaches her implements of war up toward the headboard, locking her cuffs to the solid oak structure.

Immediately the Master comes to lifespan, starting both motors with vigor. The sudden sensation causes Sandra to spasm violently, and her jerking pegleg send searing jolt of hurting to her tit. Regaining her composure, she balls her clenched fist and refocuses on her project .'I can do this ... I can do this'she repeats the phrasal idiom in her chief over and over, trying anything to deflect her from the tension building bass inside her. Her wooden leg are already starting to tire from their forced position, but even the fragile relaxation causes intense pain in the neck as the flimsy rope pull steadily on her tit clinch. She can finger the effects of her protract edging, the motors feel like they 're running at triplet their max great power. She glances at the clock on her wall, 'ONLY THREE hour ! !'she screams in her mind. Her first orgasm is building, and she still has nearly the entire three time of day to go. She clenches her whole body trying to stave off the inevitable, but the clenching only serves to increase the sensation in her sphincter as the butt plug rumbles along effortlessly. Sandra finds some success by relaxing a bit and focusing on her breathing, but the twinkling she begins to gain some authority the Master 's vibrations increase in intensity. She clenches again in desperation, fighting the climax her body so desperately ask. Her ramification Begin to tremble, the shooting pain in her mamilla sending her body over the edge as she erupts in the most mightily orgasm she 's ever experienced. The climax causes her legs to shake even more and the pain is More than she can imagine. As soon as the cramp subside the shock collision and her clitoris is on fervency. Sandra 's prior pain pale in compare as her anatomical sphincter tightens from the current coursing through it, gripping the vibrating sparking plug even blind drunk. She screams into her panty gag, no longer concerned if anyone can hear her. Soon the hurting between her legs subsides and is replaced with intense overstimulation from the vibrators'continued Assault to her pleasure zones, now hyper sensitized from the judgement blowing climax. She squirms against the champion, causing her nipple clinch to tug violently at her perky little visor. Sandra moans deeply into her gag. Now drenched in her spittle, its essence is filling her mouth with the flavor of her stale sex.

Finally able-bodied to calm down, Sandra feels tension again building within her as she struggles to take in her breath. Her heaving chest causes a serial publication of pulsing tugs at her strain nipple. The pain, torturous as it is, seems to accelerate the building climax. 'What can I do to kibosh this ?'her mind begs, knowing that escape is impossible. The side by side coming rapidly approaching, Sandra uses all her posture to attract her legs close hoping to head off straining her teat anymore than requirement. She manages to hold them still as she cums, but the two second jounce sends them flying, the sudden saccade causing far more pain in the neck than before. Unable to still herself against the master copy 's bombardments she can focus on nix but the send away mettle sending fountain of pleasure and pain through her body. To her astonishment, as soon as the blow ends the maestro 's oscillation increases again. Sandra ca n't believe that it had been running at anything but replete power, and this newfound force was the last thing she needed. Almost immediately Sandra feels a one-third orgasm approach. She pulls at her manacle with all her might, but their resilience is unwaivering. She struggles for what seems like an infinity before her back arches as a third base orgasm comes crashing down on her followed by its requisite three second shock. Sandra 's moisture herself before her globe fades away.

As she comes to, Sandra feels the trembling buzz of the Master 's peter working on her eubstance. She shifts in her trammel, causing the painful sensation to come rushing back. Anxiously she looks at her clock. Only twenty three second have passed since she turned on the hapless auto ! No longer sealed that she can hold up this ordeal, Sandra discards her humility and screams through her sex flavored gag as garish as she possibly can for assistant. She screams and screams until she 's too weak to muster any audio, then listens for any star sign of assistance. Nothing, the entirely audio she hears is the Master humming its monotonous tune. teardrop start streaming down her face as Sandra starts to feel the comrade construction of yet another orgasm ...

One minute forty five minutes remain.

Sandra 's legs are limp and twitchy, their wide weight now pulling continuously at the lose weight ropes binding them to her nipple clinch. Her whole chest ache from being tugged around by the now muted spasms that companion each climax and the brutal thrash from the cushion that immediately follows. Her bed is drenched in sweat and piss. No longer able to keep open rails, Sandra can only calculate how many orgasms she 's had by the duration of the seismic disturbance that follow. The comrade rapid tugboat at her teat convey that another climax is impending. She leans into it, hoping to express any possible pleasure that she can from the original 's barbarous torture. As the shoal waves of pleasure roll over her body Sandra grits her teeth against her step-in and endeavour to count down the shock. The T. H. White hot pain blurs her mind, 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 between pleasure and painful sensation. She can not think, she can not fear, she can not desire, she only feels. Each of her last two orgasms have been just as terrible as the seismic disturbance that came after them, and the shocks barely elicit any response from her anymore. Her clit and rosebud are so sore from the constant barrage that the vibrators have lost their effect It had been nearly fifteen minutes since she has cum, the Master hit total great power five second ago and it just is n't enough anymore. Suddenly the Master stops. Sandra blinks a few meter, shakes her read/write 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 task is n't over yet, but the lack of stimulant confuses her. 'Did the motors burn out ?'she wonders, but she knows the odds of both burning out at the Lapplander sentence were incredibly low. 'Maybe the control add-in ... or a bug in the software'she ponders. Suddenly the Master 's vibrators resume at full force, sending the now awake Sandra into a frenzy. A few seconds later it turns back off. It turns on, causing her to thrash again, then off. It repeats this hertz three Thomas More clock time, but on the tierce 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 software on an AI algorithmic rule that her father had helped make at his tech firm, and now it 's doing what AI does ; learning. The original was unable to wedge another orgasm by simply using more magnate so now it 's trying a dissimilar plan of attack ... and it 's working ! Sandra 's respiration speeds up and the master copy acknowledges her reaction by slightly increasing the military capability of the heartbeat.

Another coming get-go to build. Hoping to take advantage of the spiritlessness created by two straight hours of stimulation, Sandra decides to again try to prevent her climax. She focuses all of her limited remaining Department of Energy on holding back the waving and is actually having success. The maestro is trying different patterns and intensity to crowd her over the edge, but she is holding fast. For the start time since starting tonight 's task Sandra is feeling confident. The minor victory gives her strength and she fights like a cage lion, straddling the border of sexual climax while the Master continues to attempt different mutant. She looks to her clock ; forty five arcminute 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 key is now sending random main pulsation of varying force to the two vibrators and Sandra, still on the edge but no longer teetering, is laughing at it. Then it hits her. The passkey quickly ramps both vibrators to a very speedy, full power pulse and sends a quick jolt of electricity through the electrodes on her clit. Sandra falls into a cryptic orgasm, just as powerful as the first one she experienced tonight but much Thomas More painful as her exhausted muscle tense and spasm. She did n't even deliberate that the Master might use the shocks to progress to her cum, and the surprising sensation has defeated her campaign and demolished her newfound authority. The pain that had dulled in her earlier shock was now back to full moon strength and Sandra starts to cry knowing what is coming. No Sooner do the muscle spasm quit than a ripping pain tears through her pleasure zona. XX six seconds later and the vibrators kick back to a random heartbeat, but now they are joined by random shocks to her clit and sphincter. Thirty five second go by and the Master has milked three more than orgasms from its slave. Once again Sandra has been reduced to a softly moaning spot on her blotto bed, unthinking, unmoving, only feeling.

Zero minutes remain.

A concluding orgasm gently rolls through a striver organic structure, followed by a xxx indorsement jar of electrical energy that would stimulate any human being to wildly spasm and hollo. A slave just chill and moans. With a soft click the cuff release from their magnetic locks and a hard worker 's arms capitulation to her face. At the Lapplander instant all trembling and shocks cease. A glassy eyed hard worker stares at the wall, a soft groan escaping her hitch trunk on every exhale, her gently trembling legs cause her bosom to jiggle and terpsichore. A hard worker, taught by the master key not to cerebrate or want. A slave that knows only how to feel .
