Catherine Makes A Change

By Petricia

     She stood in the doorway and gazed at it as she had done countless times before. Gleaming stainless steel, black lacquer, soft black leather, chrome buckles. It was beautiful, a work of art. It was hideous, evil, cold- a thing to be feared and reviled. It dominated the room, as it dominated her thoughts, and holding the promise of something so sinister it made her quiver to think about it.

     The device was Catherine’s own creation, a product of her fantasies. She had begun designing it in her final year at MIT. It had taken several years, lots of work, and all of her engineering skills to create. It stemmed from her love of self bondage and her desire to always push her limits. She had developed numerous ways to place herself into strict bondage, devices to whip herself, fucking machines, but this was by far her masterpiece.

     Even now as it rested in the center of her personal dungeon which she had fashioned from her spare bedroom, she wondered what had possessed her to build it. She never had planned to actually use it. She had rationalized a hundred times that it was just an experiment, a test of her engineering skills. Deep down she knew it was more than that however. While its intended purpose was so dark and unthinkable as to cause her to shudder, its presence in her home also drove her mad with lust.

     She had used her dungeon only once since completing the device. She had been lying on the floor in a strict hogtie of her own making when she had the strangest feeling, as if it were watching her, calling to her. That evening she had locked the door to the dungeon before going to bed. Irrational of course, but it seemed to have a life of its own. Since then she had stopped to look at it a thousand times, but never dared remain in the room for long. Each time, it seemed to beckon her, to taunt and tease her, promising to fulfill her submissive desires. She knew it was ridiculous to think of an inanimate object in this way, but try as she might she could not shake the feeling.

     Catherine’s hand wandered to her breast, caressing and teasing the nipple through her blouse and sheer bra. Closing her eyes, her other hand found the catch on her pants and deftly released it, letting the soft fabric slide down her long legs to the floor.  She expertly found her target through the already wet panties, eliciting a small squeak of delight. The pleasure soon built to near crescendo and just as she was about to climax her eyes fell upon the beautiful, almost mesmerizing device.

     Catherine’s world exploded into a million shooting stars, swirling around her vision. Her knees buckled and she collapsed to the floor in ecstasy. As her hands worked furiously she came again and again, her mind melting into an almost unbearable state of bliss. Such was her pleasure that she was unaware of her own screams, her whereabouts, or anything else. Catherine’s world went black.

     As consciousness slowly crept back in Catherine felt her disgust rise in her throat. Not that she was unaccustomed to pleasuring herself-far from it. Her revulsion came as she peered through sweat soaked locks of golden hair at the insidious machine. How could she be so turned on at the thought of this horrible thing?

     ?This is it!? she proclaimed. ?Next weekend you are out of here!?

     ?My god,?she thought, ?now I’m talking to it!?

     She knew the following weekend was the beginning of her vacation so she decided to remove the temptation. What had taken her several years to create, she would destroy over the course of a weekend. She would dismantle the device and get it out of her home, out of her head. She would return to her ‘normal’ life. She couldn’t help but smile ruefully at the irony of that term. No one normal would devise such a thing.

     The following week was, in fact, fairly normal. Catherine worked for a major pharmaceutical and medical equipment manufacturer. She loved her work and was pleased that her designs were helping patients all over the world. It also allowed her access to materials she had used for her little projects at home. While she wasn’t close with many of her associates, she did date a few and was, up until recently,seeing Robert, a chemist from the R and D department. She liked him well enough and sex with him was good, although nothing like what she experienced in the context of her bdsm sessions. She had approached him early on about her love of bdsm but it simply wasn’t in him to dominate her. She had agreed, albeit reluctantly to keep the sex straightforward and resolved to simply keep her bondage sessions a one-woman show. Since their relationship was very casual it had presented no real problem.

     That week kept Catherine quite busy at work, trying to get as much work done as possible before her vacation. Her nights, however, were more difficult. Her dreams were filled with thoughts of the machine, waiting quietly down the hall. In her dreams it actually took on the role of her Master, deciding her fate as easily as if deciding what to have for dinner. In all instances it had control of her, making her its plaything. She awoke many times a night, frightened, alone, and yet that familiar fire between her legs burned hot. While the dreams frightened her, she masturbated often afterwards, her desire not permitting sleep.

     At last Friday evening was here and Catherine hurried home to begin her much deserved time off and to rid herself of the item which had haunted her for so long. As the front door closed behind her she had a mixture of emotions. On one hand she was happy to be divesting herself of the conflict she seemed to suffer at the hands of this creation of hers. On the other hand she felt almost as if she were a traitor, betraying that which she had created, a part of her, and she of it.

     Brushing aside these ridiculous notions she decided to make a salad for herself and then a nice hot shower. Surely she would feel much better then. As she ate it occurred to her that she could have begun dismantling the device when she had first decided to do so. Why had she waited so long? Did she really want to get rid of it? Of course she did! She resolved to begin immediately after she bathed.

     As the shower water ran, Catherine quickly stripped of her work attire, perusing the figure in the mirror. Her long blonde hair fell about her shoulders, reflecting the light sensuously. Her breasts, while not especially large, were perky and without any sag. Her little eraser tip nipples were light pink and slightly upturned. Her waist was trim and her hips narrow. She considered herself too skinny, envying those girls with a little more curve than she possessed. She always marveled at her pubic mound, devoid of any hair through extensive laser treatments. It was her one outward compromise to her latent submissiveness. She considered a bald mound so very slave-like. Of course the laser treatments hadn’t stopped there. While she was naturally lacking in much body hair, she still had determined to permanently remove all of it below her neck, and that is just what she did. Her longs silky legs were evidence to that.

     Catherine stepped into the shower and let it wash away the effects of a day at work, the commute home, and, to some extent, the inner conflict she was experiencing. The soothing jet of warm water relaxed her muscles and calmed her nerves. She took a few moments  to luxuriate in fragrant body wash and to shampoo her lush golden locks. It occurred to her that she had a job to do and should get started. She reluctantly turned off the water and, after wrapping her long hair in a thick towel, patted herself dry and wrapped a towel around herself. In her bedroom she began to dress in the denim shorts and old t shirt she usually wore for chores.

     After picking up some tools from her garage she made her was purposefully back to the dungeon and unlocked the door. As it swung open her resolve wavered. She set her tools down and stood transfixed. Gazing at the gleaming steel she couldn’t help but feel she was engaged in a war of wills-hers against the machine. Of course she knew it was all in her mind. It had always been, but still the feeling persisted.

     Catherine suddenly felt over dressed, especially in its presence. Hypnotically, her hands moved to the snap on her shorts. She had lost the battle! Her eyes welled with tears as the shorts slid down her legs. Stepping out of them she then slowly pulled the t shirt over her head and let it join her shorts on the floor. She stood there staring at the machine, her sheer panties her last line of defense. Slowly she slid them down her smooth legs, letting them fall to the floor to join her other clothes.

She wandered back to her bedroom and, opening her lingerie drawer, found a new pair of white seamed stay up stockings. She removed them from their package, letting them glide through her hands and across her arms. Tiny goosebumps rose and she held them up to her cheek, feeling their silky smoothness.

     ?What am I doing??she asked her reflection. ?I’ve got to stop!?

     Catherine sat on the bed and rolled first one and then the other stocking up her long legs, the lacy tops stopping a few inches from her now heated sex. As if in a trance she walked to the closet and picked out a pair of white patent 6? stilettos with tiny buckling ankle straps. Sitting down she slipped her feet into the sexy shoes, buckling them around her slender ankles. As she stood her legs were instantly transformed into long, sleek, shapely pillars of ivory perfection. She loved the way they looked and her sex began to flow as she admired her look in the full length mirror.

    ?Well, I have time still. I can begin work later? she again rationalized.

     Feeling sexier by the minute, she moved back to the bathroom, hips thrust slightly forward and swaying seductively. She grabbed her blow dryer and styling brush, working her blonde locks into a sexy lion’s mane of golden tufts. Satisfied with her look she began to apply makeup- deep blush on her cheeks, heavy black eyeliner and layer upon layer of mascara, dark charcoal eyeshadow, and deep scarlet lipstick. She looked the picture of lust and was proud of how well she had done. As she was reaching for the light switch she had a sudden wild idea. She quickly grabbed a razor from the drawer and before allowing herself the opportunity to change her mind, deftly removed her eyebrows. Reaching into her makeup drawer she removed a black eyebrow pencil and began to pencil in her new eyebrows. While she had never done this before she was happy with her work, thin black eyebrows raised in a slightly surprised arch. She added shimmering gold highlights just below to emphasize her brow line.

     Her sex flowed freely now, looking at the vision in the mirror.

     ?My god, what did I just do?? she said aloud.

     While her rational mind still struggled valiantly to remain in control, the fire in her womb made certain it was hopeless. The fire raged and nothing short of a natural disaster would change the course of events. She still rationalized that this was just for a while and she would work on destroying the wicked, beautiful temptation down the hall.

     Taking one last look in the mirror Catherine switched off the bathroom lights and struggled down the hall on unsteady legs, due to the impossible heels and her own nervousness. The pit in her stomach grew steadily with each step, as did her desire. Finally, after what seemed an eternity, she reached the dungeon. Her breath caught in her throat as the machine came in to view. She had seen it a million times before, had designed, created, assembled every inch of it. But now, standing before it, she felt completely in awe of it. Both terrified and drawn to it, she mused that this must be the feeling when a slave gives themselves to a Master. Of course she had no intention of giving herself to this object, no matter how beautiful it was or how erotic.

     The walls of her dungeon were covered in mirrors and she caught sight of herself from every angle, looking every bit the erotic vision of perfection that she felt. Dropping to her knees she clasped her hands behind her back, thrusting her pale breasts forward proudly on display. She looked down and saw her discarded clothes and considered for a moment putting an end to this and beginning the job she had intended to do. Just then she felt a droplet of her dew trickle down the inside of her right thigh and she was overcome with lust.

      ?Oh god!? she cried, voice wavering.

     Catherine dropped to her hands and knees, and crawled to her Master.

     ?Master? Where did that come from? I’m losing it for sure! Maybe I’ve already gone crazy! What if this is all an hallucination? What if I am really insane??

     The questions rolled through her head, even as she reached the machine. She reached out a hand and lovingly caressed the smooth black surfaces, the shining chrome, the strong leather. On an impulse she kissed the body of the machine and, losing ground to her questioning mind, let her tongue slither from between her cherry red lips. Licking, sucking, kissing, caressing her Master, she worked her way towards her final destination-a huge dildo mounted on a saddle of sorts. The saddle was black lacquer and was actually more of a housing for the mechanisms beneath. Catherine’s sensitive nipples brushed against it as she began making love to the dildo mounted on top.

     Catherine climbed up and knelt on the right kneepad which was mounted on one side of the saddle. Sensing no threat, as the machine had not been turned on, she swung her left leg over the saddle. The position caused her knees to be spread slightly. As her left knee touched the smooth surface of the other kneepad, she felt the tip of the enormous dildo lightly spread her labia.

     ?Oh god? she moaned loudly. Just this slight touch was driving her mad.

     She reached down and pulled a leather strap which was mounted on the right kneepad around the back of her knee, buckling it tight. Shivering, she repeated the process with the left knee, ensuing she would be going nowhere until she released the buckles. She teased herself with the head of the monster, rocking gently back and forth. She had been in this position before, in one of the many testing phases of the machine, but never with it fully assembled. Certainly not with it fully operational. She wondered how it would feel, to be here, in this position, once the power was on and the machine a very real threat. God, it turned her on to think about!

     The power switch was mounted on the body of the machine in front of the saddle. She casually fingered the switch as she contemplated how it would feel to be so close? so very close. Just a little flick of a switch, that’s all. The danger, the excitement! So very close. She added just a little more pressure to the switch. So very close!

     Catherine jumped as the machine suddenly whirred to life, motors winding up, internal computer booting up. As her heart was beating loudly in her ears, she fought desperately to catch her breath.

     ?It’s ok girl, just relax. Nothing will happen if you don’t do anything. The power is on, that’s all. You’re ok? she reassured herself.

     Still, being this close, so very close. It was so dangerous, so exhilarating.

     The kneepads were mounted so that they ran from side to side, allowing the occupant’s knees to spread as wide as physically possible.They were currently locked in place. The release mechanism was mounted just behind the power switch and once released the occupant would have to use their inner thigh muscles to either hold the knees together, or let them spread apart, allowing the occupant to be lowered onto the dildo. Catherine teased the release button with her fingernails, wondering how it would be to have to hold her knees in to avoid being impaled by the massive intruder. She could do it, she was certain. She was young and strong, and she could hold it for an hour. Couldn’t she? Yes, of course she could. Should she try? Did she really want to? Oh, she did, for sure, but if she failed?.

     She brushed aside the idea of failure and reached to a high table to her left.  She opened a small refrigerator and removed a vial of thick opaque liquid which she then placed into a small microwave and warmed it. She also picked up a thick, squishy flesh colored dildo, complete with balls. Opening the vial she poured the substance into the base of the dildo and placed a cap on it to seal it. Casting aside the vial she inserted the phallus into a clamp mounted on the upright column of the machine directly in front of her face. Barely able to control her trembling hands, she then picked up a bottle of baby oil and squeezed some over each breast. As she massaged the slick oil into her breasts a thousand sparks shot through her body, eminating from her now highly sensitive nipples. The low moan that escaped her lips was that of pure lust.

     Reaching down she found 4 surgical clamps attached to tensioned cables leading into the saddle. There were two clamps on each side. She gingerly attached a clamp to an already wide splayed lip, wincing slightly with the new pinch. She repeated the process with the other three. The cables were pulling, but she could certainly bear it.

     Catherine was near the point of feinting, her pulse pounded in her temples, her breath came in short gasps, her stomach tied in knots. She was so close! Could she? Should she? She had come this far. She was almost there. Should she stop or go on? Did she dare? She was so close! So very close!

     She again toyed with the release button. Just a little pressure, just a little more?.

     Catherine’s knees suddenly slid outward, the monster splitting her lips wide and driving an inch and a half into her. She shrieked, out of both shock and pain as she was brutally penetrated. Quickly she pulled her knees back together as far as she could. She knew that once the knee pads were released that the machine was active and prepared to strike. There was only one thing left to do and she would be at its mercy for 60 minutes. While she would still be in control of how far she would be impaled on the dildo, that would be her only measure of control. Thus was the design of the machine-to keep her in its grip for the hour she had programmed it to, and force her to chose her own fate.

     She reached down to the body of the machine and took some weight on her arms, easing some of the strain on her inner thighs and allowing the intruder to slip out of her until just the tip was once again teasing her pussy. She had, unfortunately, forgotten about the oil remaining on her hands. As her hands began to slide to the sides of the machine, the dildo began slipping back inside her. Clamping her knees together again, she considered unbuckling the straps and removing the clamps. At this point this was her only way out, as the slides for the kneepads could not be locked down again from her position, nor could the machine be turned off.

     Just as she was reaching for the buckle holding her right knee in place, the vibrations began in the dildo. Catherine gasped in surprise even though she had known it was coming. Losing concentration for a moment she allowed her knees to open slightly, the dildo sliding into her slightly. She soon discovered that she could fuck herself, even if only slightly, by allowing her knees to separate slightly, and then closing them again. As she developed a rhythm she caught sight of herself in the mirrored wall.

     ?What a slut!? The words came out so naturally. The sight just served to spur her on. Just one last step! So close. So very close! The reflection was a picture of pure lust! So erotic! So sensual! Just one thing missing, just one thing! So close! So very close!

     Catherine reached both hands behind her. Placing them palm to palm she bent forward slightly and, reaching up as far as she could, managed to slip her arms through the two leather loops. So close, so very close! Catherine realized she was crying again. As her brain screamed for her to remove her arms from the loops she pulled hard down towards her behind. As tears streamed down her cheeks the loops, attached to a vertical pillar behind her, began to tighten. At first she felt her wrists enclosed, palm to palm and then her elbows were drawn together. Tighter and tighter the upper strap became, until her forearms were welded together. She both heard and felt the twin clicks sealing her fate for the next 60 minutes.

     ?Noooooooooo? she cried out, her mind in a frenzy. What had she done? How could she be so foolish? How had she allowed it to go this far? Now it was too late. Her fate was sealed!

     In her panic she had allowed her knees to open more. She was jerked back into action by the dildo slipping deeper into her than before. Quickly she pulled her knees together. Breathing heavily she tried to regain some composure. She tried to struggle with her bonds. It was pointless, as she had designed the machine too well. She was going nowhere. In her struggles, however, she had failed to keep her knees together and the dildo forced its way into her again, the pain signifying it was deeper inside her this time.

     Simultaneously the vibrations kicked up to a much more serious level. The vibrations caught her off guard and she threw her head back in ecstasy. As she did she once again caught sight of herself in the mirror. The picture was complete now. The slave girl in the mirror was a study in erotic submission. Riding the dildo buried partially inside her, arms pulled back tightly behind her, her oiled breasts set high on her chest displayed proudly by her stringent bondage, blonde hair flaying wildly about. The sight was too much for her and she purposely allowed her knees to spread a bit further, impaling her stretched pussy even deeper.

     Just then the next phase of the machine’s programming began. The entire assembly containing its hapless victim moved forward toward the large vertical column in front of her. As the dildo which she had placed at eye level came closer and closer, she fought hard against a new wave of panic. She had no choice but open her mouth to accept the dildo as it insisted itself against her closed lips. While she could have avoided it, she no longer wanted to. She came to a stop only inches from the column and the carriage locked in place. The dildo was buried deeply in her mouth. She had measured perfectly as she could not extract it. Attached to the vertical assembly were two funnel-like cups placed exactly where her breasts were. The sound of a vacuum filled the room and she could feel the air rushing past her nipples as it was drawn into the cup with great force. She leaned back as far as her bonds would allow, which was very little. But even with this effort her slick breasts were brushing the edge of the cups. It took all of her concentration to keep her breasts from being sucked into the cups. While she was certain the sensations would be amazing, she also knew it would be bad, very bad.

     The vibrator in her saddle ramped up to full song and she was plunged into a new world of sexual frenzy. It was driving her wild with desire, her orgasm fast approaching. She watched herself in the mirror as she let her knees slide apart slightly. The monster was deep inside her now as the vibrations abruptly ceased, having been programmed to a random setting.

     Catherine took this opportunity to rest as well as she could, breathing deeply and trying to ease the tension on her inner thighs. Her muscles were beginning to tire and it was getting more difficult to hold herself off of the huge dildo. There was also the little problem of her desire to embed the huge thing deep inside her womb. But to do so would mean disaster. Tiny beads of sweat broke out on her forehead. She was concentrating on not sliding down on the dildo any further as well as making it as easy on her thighs as possible.

     Just as she found a suitable compromise the dildo in her stretched pussy exploded back to life with the strongest vibrations yet. Her shock and surprise caused her to bite down hard on the dildo stuffing her mouth. In response it squirted a large dose of the gooey liquid down her throat. She nearly gagged but was thankful she didn’t have to taste much of it. The mixture slid down into her tummy and while she was anticipating one effect, she was uncertain about the other.

     The sticky liquid contained a general anesthetic which was produced, of course, by her company. The effect of this ingredient was certain-she would soon feel a little drunk and sensations would be deadened. The other ingredient, however, was what gave her cause for concern. It was a highly experimental aphrodisiac being developed by her company. Robert had told her of it and she had begged him to let her see. She had stolen a small amount of the drug not being used for testing. She remembered he had mentioned that it was not fully tested and that a full strength dose caused test subjects to go nearly insane with lust, their conscious will succumbing to their desire.

     This sample she felt was sufficiently diluted-she had added only a few drops. The danger, however, still existed, as she had not yet tried it. The thrill of the unknown had added to her excitement when mixing the vile concoction. The final ingredient, and cause for her revulsion, was human sperm. Her friend, Sandra, had managed to obtain it from a fertility clinic. She didn’t really want to know how, but was assured it was all completely safe- just hadn’t met the requirements of the clinic.

    Catherine felt the first numbing effects of the anesthetic. A bit lightheaded, she doubled her efforts to remain in place. Then it hit her, the first wave of unbridled lust. Her pussy throbbed, juices leaking freely around the head of the monster. The feeling overcame her, and as she realized just how powerful the drug was she thrust herself down onto the huge dildo. The vibrations turned her insides to jelly and her willpower was losing ground. She sucked hard on the penis filling her mouth, wanting more of the warm, euphoric feeling. Her mind told her not to swallow it, but down it went anyway. As tears streamed down her face she feared the worst. The monster buried deep in her womb was driving her mad, the drugs were quickly overcoming her. Oh yes, she definitely should have omitted the sex drug from her cocktail. Even as this thought occurred to her, a new wave of passion swept through her. She sucked frantically on the penis, savoring the pungent contents that had only a few moments earlier had repulsed her. Even as her mind screamed at her to stop, she continued to drain the laced sperm cocktail into her belly. Now riding the dildo for all she was worth, she suddenly thrust her head forward, forcing the quickly draining penis down her throat. She gagged only slightly as she began to fuck her throat with the squirting phallus.

     As she rode the enormous dildo buried in her womb she felt more and more loss of control. She had just enough presence of mind to hold off driving the dildo in to the hilt. Just as the vibrations were beginning anew, she lost her concentration on her posture and felt her oiled right breast slide past the lip of its cup, the powerful suction drawing it deeply into the recesses of the gleaming cup. Yelping in shock around her oral lover, she suddenly felt the left breast sucked into its cup as well.

     ?No, god no? she screamed into her penis feeder.

    She tried desperately to pull her breasts out of the cups, leaning back as far as she could, but it was in vain. Her breasts were trapped and she was powerless to extract them. This sudden dose of reality brought her to her senses slightly and she realized with alarm that her behind was nearly touching the saddle and the monster was nearly buried to the hilt inside her. She was certain the hour must be nearly up and all she had to do was to remain here without moving until the timer released her.

   Just as she was regaining her confidence that she would get out of this, the last and largest dose of the aphrodisiac took hold and the sensations of suckling on her trapped breasts coupled with the low hum of the dildo melted her resolve for the last time. She began to fuck her drenched pussy again, trying desperately to make it. And she was getting closer by the minute! Faster and faster she pumped the mammoth intruder, bliss just within reach.

     Finally, the monster went to full vibration and she knew she would make it. She also knew she wanted it completely inside her, buried as far as it would go. She knew what this meant and it terrified her, but she could not control it now.

     ?No, no, nooooooooooooo!? she screamed around the penis filling her mouth.

     She spread her knees as far as they would go, the huge monster impaling her to the hilt. She felt the tip press against her cervix, the base pressing into her splayed labia. The final phase of her devilish engineering began as soon as she slammed down into the saddle. Two loud pops from the breast cups resounded over the sound of the vacuum, accompanied by blinding pain in her nipples.

     At the same time, the cables attached to her labia clamps tensioned, assuring she would stay put. A split second later four similar loud pops filled the room followed by similar intense pain in her stretched pussy. Thankfully she had the forethought to use the general anesthetic, slightly dulling the pain. It did little, however, to abate the orgasm that ripped through her body, smashing her world to atoms.

     ?Oh god, oh god oh gooooood!!!!?

     Nothing could have prepared her for the feelings she was experiencing, the orgasm aided by the drugs coursing through her.

    As Catherine flailed and bucked atop the machine, her mind still unable to comprehend, her fate had been sealed. She had panned it all perfectly and the evil creation had performed exactly as it had been designed. When it would finally release her, the breast cups, fashioned from an incredibly hard alloy, would be a permanent part of her. Surgical steel rivets had been pierced behind her nipples, mating with matching holes in the tips of the cups. There was no way to cut the rivets which had been recessed into the cups. Her nipples were now permanently out of reach.

     In addition, the dildo had been similarly attached to her labia by rivets passed through respective clamps, sealed inside her permanently. The machine would detach the dildo at the appointed time. She need only remove the clamps. Once free of the machine she would be filled permanently by the huge dildo. It was hollow and perforated for the purpose of elimination and health but could never be removed. It had a protrusion in front with a hollow recess that was pressed firmly over her clit, keeping it hidden for the rest of her life. She would never receive stimulation again, clitoral or otherwise. The dildo had been designed with additions to aid in her new modifications. It had a dildo plug that could be inserted for everyday use, as well as a lifelike sleeve which, when inserted, would allow her to be fucked, the sleeve providing a loving embrace to the mans penis She would be able to provide pleasure but not receive it. In short, the machine had created a living fuckdoll!

     As Catherine’s orgasm eventually ebbed, tiny ripples shook her body. She had long since collapsed, hanging limp in her bondage. She had not wanted this! This is exactly why she was terrified of the horrible machine. She had been changed forever.

     The timer sounded-60 minutes.
