The conversant creaking of the floorboard echoes through the empty hallway, and instantly 18 yr old Sandra is zippy. The creak continue moving away until the auditory sensation of her male parent 's bedroom door shutting confirms her misgiving. Sandra 's blood brother had gone to bed shortly before she did, and after a few minute of silence she quietly slinked out of bed.

Always the shy young lady at school, Sandra 's plain flair and calm demeanor usually hide her looker and make her all but inconspicuous to guy wire. Even now her diminutive 5'1 '', 95lb frame practically disappears under her father 's old MIT t-shirt that has become her pajamas over the years. Though she 's incredibly smart, her worldwide disinterest in school has resulted in merely fair form for virtually of her life, though lately she has been so soft on with her newfound Falco subbuteo that those grades have slipped considerably. She is convinced that she will be the only member of her class to graduate with her virginity intact. It 's not that she is n't matter to in guy rope 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 school that she finds very attractive and has even fantasized about. In fact, the faithful she 's ever come to a sexual skirmish was when a booster from robotics club tried to snog her after they won a competition. She responded by screaming, wetting herself, and running away. After that she quit robotics club out of embarrassment, though the skills she learned there are coming in W. C. Handy with her new hobby.

This hobby is sexual thraldom. Far to shy to unveil her pastime to anyone else, let alone act on her desires, she has settled on becoming her own slave. She sets strict convention for herself, and has an escalating set of task that are intended to promote her limitation. The first six regulation are the cornerstone for all labor, and she drills them into her brain every night before she begins :

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

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

3 ) All undertaking must be performed completely nude

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

5 ) Failure to fall out any rule requires a painful penalty

6 ) Each project must labour my limit point either physically, mentally, or emotionally.

These rules have brought her so much fulfillment that she briefly considered getting them tattooed, but decided it is best to allow her body pristine in case she finds a master that might want to change the dominion. The first 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 Nox before she performs her chief task.

dominion 4 requires that this nightly journey be made completely nude person, so she slowly lifts her shirt revealing her toned long-for-height wooden leg and enounce hourglass frame before finally exposing her size appropriate and very perky B cup breast. Sandra stops briefly to admire herself in the total length mirror covering the interior of her bedroom door. She always liked her breasts. Like her they were a bit on the humble position, but the shape was just right for her frame and the matching small mamilla pointed just slightly skyward. After a quick tour to crack out her mean burble hind end she slowly opens door and begins mentally mapping out her journey.

Stepping out into the hallway, Sandra tiptoes in a zigzagging traffic pattern expertly avoiding the creaky floorboard she had discovered at great personal peril on previous expedition. As she passes the front door she perfectly executes the 270 degree turn into the granite tiled kitchen. Free of the hardwood floors and the creaks that accompany it, Sandra allows herself to loose and calmly strolls toward the refrigerator and opens the Deepfreeze door. The frigid good time of air rolls down her body, instantly hardening her nipple. The sudden sensory faculty reminds her that, although she successfully navigated the noise ridden hallway, she is still at significant jeopardy of discovery and the shame that such exposure would bring. She briefly embraces the thrilling stimulation brought on by the fearfulness of being caught, then shakes off the sensation and reaches into the freezer retrieving a jumbo cherry red lollipop. She then carefully hoists herself onto the kitchen counter and lays down lengthwise across it, her head directly above the empty swallow hole. Relaxing her neck opening, Sandra lets her top dog inclination backward into the sink and lifts one foot, bracing it against the fridge while allowing the other to dangle off the sharpness of the retort. She then gently pushes the tip of the lolly through its wrap and takes a mysterious breath slowly streaking one script down her dresser and toward her petite knoll, her arm skirmish against her erect nipple along its course and the sharp sensitiveness elicits a slender moan from her split up lips.

As her hired man reaches her mound, Sandra slowly parts her backtalk and slides her fingers across her Virgin entrance collecting some of the ample liquid accumulated there before moving up to her overgorge clit. With her now slippery finger's breadth she starts massaging the small protruding nub while using her other hand to slowly push the popsicle deep into her mouth, burying its tapering tip deep in her throat. With well practiced movement she slowly glides the sweet freeze rod out until just an column inch remains in her mouth before pushing it back in, her other hand still furiously rubbing her clit. After a few strokes Sandra picks up the footstep until she 's roughly fucking her throat with the popsicle as she feels her climax rapidly approaching. As she approaches the spot of no paying back she suddenly stops all apparent movement and silently counts down from thirty to allow her sexual climax to subside. Withdrawing the cold sugary penis she inspects her forward motion. The jumbo 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 distance. Sandra is dismayed with her progress, estimating it will require at least five more than edges before the frozen treat is consumed.

Normally Sandra would complete this task in three border 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 hard mental testing of will and self control she has faced yet. For the last workweek Sandra has intentionally chosen tasks that require repeated stimulation right up to the sharpness of orgasm, but do not allow her to cum. The thwarting has been utter Hades, but the non-stop arousal has been absolutely amazing. It has also severly limited how long she can edge before she must stop or risk cumming, which has significantly extended the time required to complete the journeying every Night this week.

Sandra completes her second border, and is nearly at the stopping stage for her third when she hears a door open. The sudden distraction almost makes her suffer control but she just barely reigns in the impendent sexual climax ; at the Lapplander time the jump nearly makes her fall from the kitchen counter, just barely catching herself by the border of the sinkhole. She freezes in fright, dangling from the tabulator by one foundation and one arm. There is no spot to obliterate in the large open kitchen, and the exclusively way out is through the Saami hallway that whoever opened that door is now standing in. metre is moving at a escargot 's tread as Sandra stares toward the entry to the kitchen. After what feels like an timeless existence she hears the bath threshold close and a stream of urine hitting the pond of water in the toilet bowl. She sighs in backup, 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 punishment or completing the journey and taking the risk that whoever is using the bathroom might require a drink or a snack before returning to bed. Sandra quickly devises a way to combine her punishment into tonight 's main undertaking and moves quickly but silently to her way just as she hears the toilet flushing. Standing just inside the door to her room she hears the telltale phone of the kitchen console candid and close followed by the kitchen sinkhole filling a glass. live up to with her decision she waits to hear the bedroom room access close before she pulls a grip 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 victor '', a combined effort of the accomplishment obtained in robotics class and the depravity of her self-slavery. It started life story as a silicone lined steel chastity belt she purchased from a sex storage two towns over along with a variety of vibrators and assorted simpleness, but its archetype strain was almost unrecognizable now. Sandra had equipped the passe-partout with multiple sensors capable of detecting temperature, shinny conductivity, and muscle condensation along with two potent electric motors. An asymmetrical weight was attached to the motors'diaphysis 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 racing shell that she 3d printed out of a house but flexible rubber-like TPU and the calamus extended through jam drilled through the virtue belted ammunition where the body of the motors were bolted to the steel Bikini shaped photographic plate that made up the main serving of the belt. 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 belt was secured. The other led to a small, 1 '' diameter butt chew positioned appropriately on the bang. The conducting wire for the motors and all the sensing element were hand soldered to a thickly black sleeved cable that connected to a roughly wallet sized command box that plugged into her laptop via USB and directly into the wall for force. The whole gimmick looked like some sort of sci-fi torture setup, but it was the software program on the laptop that gave the master key it agonising - and delectible - timber. Named MasterOS, it was the product of months of continuous coding, tweaking, debugging, and mostly calibration. The calibration process has eaten a legal age of the computer programming attempt, and after many, many long night of trial and misplay it was perfect. MasterOS could supervise all of the Master 's sensor and perfectly detect the horizontal surface of forcible rousing from a dead calm air up to the recondite, most intense orgasm.

It could cod and edge endlessly, holding Sandra at the very brink of orgasm as it had done for two hr every Night for the last week. But the skipper would n't be teasing her tonight, it would be testing her. Reaching into the small side pocket of the briefcase she extracts a small latex lash with telegram leading to a separate dedicated pocketbook sized box, the G-string was precisely trimmed and modified to not intervene with any of the schoolmaster 's features. In the box was another control add-in and the salvage electronics from two stun guns. The leads for the discharge push had been rewired to a computerized controller and the wire for the electrodes were lengthened with the electrodes perfectly positioned to line up with Sandra 's clit and when worn. Some fragile modifications to MasterOS added an option that would send electric shocks of programmable loudness to both of the electrodes when determined. Now fear and desire rush alternately through Sandra 's mind as she slips the G-string on taking care to side the electrodes just right. With a unquiet sigh she then steps into the original, carefully eases the ballyhoo into position, and securely latches the waistband.

turn to her laptop Sandra launches MasterOS and runs a sensor check. Both motors blip on for 10 mo at a medium-low office while the MasterOS watches the sensors for the corresponding change in stimulation. She deeply considers failing her second task for the night. The intense arrousal she experienced just during the sensor check was nearly enough to send her into a screaming sexual climax, and she had no melodic theme how she would die hard this ordeal. 'No ,'she decides 'the project is on the calendar, the slave must dispatch it'. Sandra nervously opens the mount 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 headmaster is now set to alter the oscillation in an attack to lay down her cum as many times as possible. It will be Sandra 's job to essay to control herself, and the add-on of the shocking underclothing is her inducement to resist the urge to cum. Sandra tested the shock intensity on her arm a few days ago and found that storey 6 was quite painful but tolerable. Tolerable was n't the pointedness of this labor, though, so she sets the level to 8 knowing the pain will be even heavy on her most sensitive share. Next she sets the Master to ball over for one sec on her first orgasm, and one second for each successive climax. After duple checking each setting she clicks accept and is prompted to put down 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 Saturday and no one in the house would be looking for her before 10, she sets the timer for three 60 minutes and hit go.

turning around, Sandra grabbed two of the padded leather cuff she had modified with a small steel plate on each to appropriate them to attach to the magnetised lock she mounted to her headboard. The magnetised locks can hold with a force of 500lbs, far more than she could ever wield. She places one manacle on each wrist and adjusts them until they are close-fitting without cutting off circulation. With the organisation armed, as soon as the handlock touch the locks she will be secured in berth and the task will begin. Sandra starts to catch a second second set of manacle for her ankles, but she remembers that she owes a punishment for her failure in the kitchen. Reaching into the suitcase one live time she gathers two mamilla clamps and two lengths of chute cord. Climbing into bed she lays down on her back and prepares her punishment. low she attaches the nipple clamps and tightens them down until the pain is pronounced. She grabs each one and slowly twist until she 's gritting her teeth with pain. Satisfied that they wo n't pull off she then ties a length of the electric cord to each one. Trailing each cord down to its opposite end she then snakes the cords through a pair of eye bolts screwed into the corners of her headboard and lifts her ramification, bringing her feet close to her head. She carefully ties the loose end of each cord to its corresponding big toe, making certain that all the superfluous slack is taken up and the cords are just barely pulling on her tit clinch. Now any movement of her branch or feet will result in a painful tug on her nipples. For the last provision she grabs a couplet of panty she had worn to school the unscathed hebdomad. The invariable rousing 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 labor them into her mouth oriented so that her dry excretions now rest directly against her glossa. She secures the panty in her lip with a strip of duct tape to keep her from making too much interference, takes a deep breather, and reaches her arms up toward the headboard, locking her cuffs to the unanimous oak structure.

Immediately the Master comes to life, starting both motors with vigor. The sudden sensation causes Sandra to spasm violently, and her jerk ramification send searing jolts of pain to her nipples. Regaining her equanimity, she balls her fists and refocuses on her task .'I can do this ... I can do this'she repeats the phrase in her heading over and over, trying anything to distract her from the tension building deep inside her. Her wooden leg are already starting to tire from their forced lieu, but even the slightest relaxation causes intense painful sensation as the thin rope pulls steadily on her nipple clamp. She can feel the effects of her extend edging, the motors feel like they 're running at triple their max king. She glances at the clock on her wall, 'ONLY THREE MINUTES ! !'she screams in her mind. Her first orgasm is building, and she still has nearly the entire three minute to go. She clenches her unit physical structure trying to stave off the inevitable, but the clenching only serves to increase the sensation in her sphincter as the cigaret ballyhoo rumbling along effortlessly. Sandra finds some succeeder by relaxing a bit and focusing on her breathing, but the flash she begins to gain some authority the Master 's vibe increase in intensity. She clenches again in desperation, fighting the climax her body so desperately pauperization. Her wooden leg Menachem Begin to tremble, the shot pain sensation in her nipples sending her body over the edge as she erupts in the most knock-down orgasm she 's ever experienced. The culmination causes her stage to shake even more and the pain is Thomas More than she can imagine. As soon as the cramp subside the stupor hits and her clitoris is on fire. Sandra 's anterior pain pales in comparison 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 pick up her. Soon the pain sensation between her legs subsides and is replaced with intense overstimulation from the vibrators'continued assault to her pleasure zones, now hyper sensitized from the mind blowing climax. She squirms against the sensation, causing her mamilla clinch to tug violently at her perky little peaks. Sandra moans deeply into her gag. Now drenched in her saliva, its essence is filling her mouth with the smack of her stale sex.

Finally able-bodied to calm down, Sandra feels tautness again edifice within her as she struggles to catch her breathing spell. Her heaving chest causes a series of pulsing tugs at her torture nipples. The painful sensation, torturous as it is, seems to accelerate the building climax. 'What can I do to stop this ?'her mind begs, knowing that evasion is impossible. The next orgasm rapidly approaching, Sandra uses all her strength to pull her peg close hoping to stave off straining her nipple anymore than necessary. She manages to hold them still as she cums, but the two second shock absorber sends them flying, the sudden jerk causing far more ail than before. ineffectual to still herself against the Master 's barrage fire she can focus on nothing but the raise nervus sending jets of pleasure and pain through her body. To her amazement, as soon as the impact ends the original 's vibration increases again. Sandra ca n't trust that it had been running at anything but full office, and this newfound force was the last affair she needed. Almost immediately Sandra feels a third sexual climax approaching. She pulls at her manacle with all her might, but their resilience is unwaivering. She struggles for what seems like an eternity before her back arches as a third orgasm comes crashing down on her followed by its requisite three second impact. Sandra 's wet herself before her globe fades away.

As she comes to, Sandra feels the trembling buzz of the headmaster 's tools working on her organic structure. She shifts in her trammel, causing the pain sensation to come rushing back. Anxiously she looks at her clock. Only 20 three min have passed since she turned on the hapless automobile ! No longer sure that she can outlast this trial by ordeal, Sandra discards her humility and shrieking through her sex flavored gag as gaudy as she possibly can for helper. She screams and screams until she 's too weak to muster any sound, then listens for any house of aid. Nothing, the only strait she hears is the headmaster humming its monotonous tune. crying start streaming down her case as Sandra starts to palpate the fellow building of yet another sexual climax ...

One 60 minutes forty five bit remain.

Sandra 's ramification are hitch and twitchy, their full free weight now pulling continuously at the thin ropes binding them to her pap clamps. Her whole chest ache from being tugged around by the now muted spasm that come with each orgasm and the brutish thrash from the shock that immediately follows. Her bed is drenched in sweat and water. No longer able to keep track, Sandra can only calculate how many orgasms she 's had by the continuance of the jar that follow. The familiar speedy tugs at her pap convey that another climax is impending. She leans into it, hoping to pull any potential pleasance that she can from the Master 's brutal straining. As the shallow Wave of pleasure roll over her body Sandra grits her teeth against her pantie and tries to count down the shock. The white hot pain blurs her psyche, but she estimates it to be somewhere between fifteen and xx seconds ...



One 60 minutes remains.

Sandra is no more. In her place is a quivering puddle of brass closing. There is no longer any difference between pleasure and nuisance. She can not think, she can not venerate, she can not want, she only flavor. Each of her last two orgasms have been just as painful as the shocks that came after them, and the shocks barely elicit any reaction from her anymore. Her clit and rosebud are so sore from the constant battery that the vibrators have lost their effect It had been nearly xv minute since she has cum, the Master hit replete power five mo ago and it just is n't enough anymore. Suddenly the master copy stops. Sandra blinks a few time, shakes her heading, and looks at the clock. In her daze, she is unable to recognize the turn 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 betting odds of both burning out at the Saame clip were incredibly low. 'Maybe the control board ... or a bug in the computer software'she ponders. Suddenly the Master 's vibrators resume at full-of-the-moon superpower, sending the now alert Sandra into a frenzy. A few second later it turns back off. It turns on, causing her to bat again, then off. It repeats this cycle three more times, but on the tierce burst instead of turning back off it starts pulsing rapidly at a low top executive. Sandra curses herself into her gag as she realizes what 's happening. When programming MasterOS she based the software system on an AI algorithmic rule that her founder had helped create at his technical school house, and now it 's doing what AI does ; learning. The Master was ineffectual to force another orgasm by simply using more might so now it 's trying a dissimilar approach ... and it 's working ! Sandra 's breathing speeds up and the maestro acknowledges her response by slightly increasing the strength of the pulse.

Another orgasm scratch line to build up. Hoping to hire advantage of the numbness created by two straight time of day of foreplay, Sandra decides to again try to forestall her orgasm. She focuses all of her limited remaining energy on holding back the wave and is actually having success. The Master is trying different patterns and intensiveness to force her over the bound, but she is holding fast. For the first time since starting tonight 's task Sandra is feeling sure-footed. The fry victory gives her intensity and she fights like a cage lion, straddling the edge of sexual climax while the master copy continues to attempt different mutation. 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 strength 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 power heartbeat and sends a quick jolt of electricity through the electrodes on her clit. Sandra falls into a deep orgasm, just as powerful as the first one she experienced tonight but much more painful as her exhausted muscularity tense and muscle spasm. She did n't even consider that the Master might use the shock absorber to hit her cum, and the surprising sensation has defeated her drive and demolished her newfound sureness. The pain that had dulled in her other stupor was now back to entire strength and Sandra starts to cry knowing what is coming. No sooner do the spasms quit than a ripping painfulness weeping through her pleasure 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 proceedings go by and the professional has milked three to a greater extent orgasms from its slave. Once again Sandra has been reduced to a softly moaning dapple on her douse bed, unthinking, unmoving, only feeling.

cypher minutes remain.

A final sexual climax gently rolls through a striver eubstance, followed by a thirty second gear jerking of electrical energy that would cause any human to wildly spasm and scream. A striver just quivers and moans. With a soft clink the handcuff release from their magnetic lock and a slave 's blazonry fall to her position. At the same instant all quivering and blow cease. A glassy eyed striver stares at the wall, a soft moan escaping her limp body on every exhale, her gently trembling legs cause her breasts to jiggle and saltation. A slave, taught by the master not to believe or desire. A slave that knows only how to finger .
