Ellie kicked off her shoes, stripped out of her work clothes and slipped into a dressing gown. She had just got home from work. Later she would have a shower but for the moment she just wanted to relax. It was Friday evening and she was looking forward to having a relaxing weekend. It had been a very busy day at work and she just wanted to switch off. Usually at weekends she would go out with friends but this weekend she was just going to 'chill' at home.

Ellie worked as a Secretary/PA to a local businessman. Her job was reasonably well-paid so she was able to indulge her preoccupation with fashion, and also fund some of her other interests. She was still single and didn't currently have a boyfriend or a partner. Her most recent relationship had been with Ken but they had split up some six months before. She had discovered that Ken was seeing other women as well as herself and that had prompted her to dump him.

Once she found that he was untrustworthy, Ellie didn't regret ending her relationship with Ken. But she had to admit that sex with Ken had been really great. They'd had sex often, and he really knew how to 'push her buttons'. It was Ken who had introduced her to bondage. One day out of the blue he asked her whether he could tie her to the bed. After some initial hesitancy she agreed, whereupon he produced ropes and ties from under the bed. Soon he'd got her tied to the bed naked and vulnerable. To her surprise, she realised that she enjoyed the thrill of being totally helpless and unable to resist whatever Ken wanted to do with her. After that light bondage became a regular feature of their sex life.

But now Ken was history. There was no way that she was going to get back with him. She'd told him they were finished for good. Ellie was glad to be rid of Ken but she really missed the great sex they'd had. In particular she missed the thrill of having sex whilst tied up and helpless. She felt sure that she would find another boyfriend sometime soon and in the meantime she was feeling sexually deprived and frustrated. She joined some dating sites and had even looked at a BDSM dating website. But she was very cautious about using such a site as she knew that there were risks in meeting strange men with kinky predilections over the Internet. What if she met someone and let him tie her up only to discover that he was some sort of perverted monster?

Ellie had gone so far as to dabble with some light self bondage. Nothing too heavy, but she'd tied herself up a few times using the ropes that Ken had left behind. On one occasion, it had taken her hours to release herself, much longer than she had intended. But despite that experience her appetite had been whetted and she wanted to explore further. She had begun browsing the Internet looking at sites that supplied items for bondage and of course self bondage.

She'd ordered and received one or two items, but hadn't yet got around to trying them out, as she felt that her bondage kit wasn't yet complete. Ellie lay on her bed propped up on one elbow browsing the Internet on her laptop. One particular item caught her eye. The website was promoting it as an exciting new addition to their range. They described it as a 'Self Bondage Outfit'. Her curiosity aroused she clicked for more information. It was explained that the Self Bondage Outfit was actually a piece of high-tech wearable Bondage apparatus, with which the user could put them-self in BDSM.

Fascinated, Ellie read the further details. As she did so she realised that she was experiencing a growing sense of excitement. The webpage explained that the user could not only lock themselves in the outfit, but they could also program it to subject them to a variety of BDSM effects. The outfit included a range of high-tech features capable of teasing and torturing the users most intimate and sensitive areas. Importantly, the outfit's integral apparatus included powered dildos so that the user could choose to be fucked both in their pussy and their ass. The length of time for which the user would be locked in was variable, as was the range and duration of BDSM effects to be applied. An important feature was a 'panic button' with which the user could abort the session and be released, if they found that the experience they were getting was too intense. The apparatus was powered and controlled via an umbilical cable and hose which connected it to a separate power and control unit.

The website was keen to emphasise the safety features incorporated into the outfit. Firstly there was the panic button, although this could be overridden. Secondly, the whole thing was controlled by a sophisticated computer program. The user was able to enter detailed settings via the computer program, so the outfit would deliver exactly the experience they wanted. Most importantly, they could set a time limit after which the program would unlock the apparatus and release the user. There was no danger of someone locking themselves in, and then being trapped and unable to escape.

Ellie read and re-read the detailed description of the product. When she looked at the illustration she was struck by how incredibly high-tech and futuristic it looked. There was also a picture of a model wearing the apparatus. Wow! it looks really sexy thought Ellie. Then she saw that the website was offering a special introductory promotion. The first 50 customers to buy an outfit could secure a 60% refund if they completed a detailed evaluation report once they had used the product. Ellie didn't hesitate; she reached for her credit card and set about submitting an order.

The following week, Ellie arrived home from work one evening to find a card had been put through her door. A courier had tried unsuccessfully to deliver a package earlier that day. Perfect, thought Ellie just in time for this weekend. Actually, it was a double bank holiday weekend for Easter. Ellie had also taken annual leave for the four working days in the following week and so she wasn't expected back at work for 10 days. She would go to the parcel depot the next morning and pick up the package ASAP.

Returning home from the parcel depot the next morning, Ellie felt a growing sense of excitement. She couldn't wait to open the package and examine its contents. Since placing the order, she'd frequently felt a sense of anticipation and excitement as she imagined herself getting into the BDSM apparatus and experiencing all that it had to offer. She'd deliberately avoided arranging any social appointments for the next few days so that she could indulge herself in a 'self-bdsm-fest'.

Eagerly she tore off the outer wrapping from the large cardboard box. Once the box was opened she took out the item inside which looked like a rather large suitcase. This was the equipment's storage and transport case. She opened the case and took out the object that was causing all her excitement. It had looked sexy enough in the illustration on the webpage. Now that she held it in her hands it seemed positively erotic. It was a quality product. Cleverly designed it was fashioned from lightweight but robust metal alloy parts which were fully adjustable.

Ellie realised that despite the fact that it wouldn't cover much more of them than a skimpy swimsuit anyone locked in it would be quite unable to escape. Looking in the products case she saw the power and control unit, together with an umbilical cable and hose that connected it to the apparatus. Also there was a computer disk carrying the control program together with an extensive instruction manual.

First, she plugged the power and control unit into the mains so that integral batteries could be charged. These batteries were a backup in case of mains power failure. Then, she put the program disk into her laptop to install the program used to control the whole system. With the laptop in front of her and the instruction manual to hand, she set about familiarising herself with the various BDSM features that the system offered. From the description on the website she hadn't quite appreciated the full range of effects it could muster. Her intimate and sensitive areas could be sucked, grasped and pulled, vibrated, electro-shocked and of course well and truly penetrated where applicable.

Turning to the wearable apparatus itself, she examined it anew and with intense interest. At its lower end, it looked a bit like one of those metal chastity belts. Its parts were cleverly fashioned so that they were adjustable and also lockable. But that part which would be between her legs wasn't just a metal strap but a cleverly designed part of the outfit's apparatus. Once in position it would nestle very closely up against her crotch. It wasn't especially bulky, but once she was locked into the outfit she would need to spread her legs somewhat to avoid discomfort. In the outfit she couldn't sit, but she could stand or lie on her front or back.

The instruction manual emphasised how important it was to get that part of the outfit 'optimally adjusted' so that its integral dildos were correctly positioned for penetrating her orifices. Ellie decided that she needed a trial run. Turning to the laptop she programmed in a very gentle fucking by the dildos, and a very short duration locked in the outfit. But first she wanted to look at the rest of the outfit. The upper section looked a bit like a metal bikini. It had breast domes that would nestle over her boobs once she had got it on. Looking at the inner side of these she realised that they contained bits of apparatus designed to tease and torture the user's breasts. The back part of the breast section was the only part not made of metal, instead comprising heavy rubber straps. It was a bit like the back part of a one-piece swimming costume but with no rear buckle. It had metal parts at the end of each strap that latched into rear part of the metal waist belt, and also corresponding points on the top and sides of the metal front breast section.

Looking at the outfit overall, she saw that the various adjustable metal latches could themselves be locked with padlocks. The computer-controlled release mechanisms used other electromagnetic locks elsewhere on the apparatus. Also on the belt was a red button which turned out to be the 'panic button'. Again this could be locked with a padlock to render it inoperative. It could also be disabled in the control program. At the side of the belt were electromagnetic locking points, into which accessories such as chains or wrist cuffs could be latched to be only released at the command of the control program. There was nothing for it but to have a go.

With a new surge of excitement Ellie put on the waist belt and carefully adjusted it closing the latches. Then, taking hold of the crotch part of the apparatus she manoeuvred it into position between her legs, locking it onto the metal belt adjusting it as she did so. Satisfied that it was correctly positioned she closed the latches without deploying the padlocks. Then taking hold of the breast section, she carefully applied it to her breasts making sure that they were comfortably positioned within the breast domes. Straps from the rubber back section came over her shoulders to lock into the top of the breast domes, and underneath her arms to lock into the side of the domes. Finally, the bottom end of the back straps locked into corresponding points on the back of the waistband.

Standing in front of the mirror, Ellie regarded her image critically. Wow she did look hot. She looked like some sexy super-heroine. She particularly liked the way that the back part of the crotch section nestled snugly between the cheeks of her ass, but left much of her ass exposed and on full view. It was a bit like wearing a thong. For this first test run Ellie chose not to use padlocks to secure the various latches on the apparatus or indeed to disable the panic button. She might use that option later. But she did attach some wrist cuffs to the locking points at the side of the belt. She wanted to see whether everything would be released as instructed at the end of the session.

Here goes she thought and plugged the umbilical hose into its connection at the apparatus between her legs. Then turning to the laptop she pressed a key to initiate the programme sequence. She now had 60 seconds to get herself in position. She lay on the bed on her back and looked over the laptop where the programme was counting down. It reached zero and then things started to happen between her legs. Slowly, a dildo pushed his way up into her pussy making her gasp. She'd forgotten that when ordering the unit she'd specified large dildos. Then, a second dildo slowly pushed its way up into her ass hole.

She was just beginning to enjoy the experience when the program terminated the trial run after just two minutes as she'd specified. The two dildos gently withdrew into the apparatus between her legs. Then electric latches released the outfit so that had she been standing it would have fallen off of her. At the same time, electric latches at the side of the belt released the empty wrist cuffs she had fixed to them. The cuffs fell away. Good It works she thought. At least I know that the damn thing will let me out when it's finished playing with me.

Now that she had completed a gentle trial run, and was satisfied that the outfit would release her at the end of a specified period, Ellie was keen to really put it through its paces. Turning again to the instruction manual, she considered which of the outfit's BDSM effects she wanted to try. Having made this choice, she would need to decide the strength or intensity of effects she wanted, and how long she wanted to be kept locked in the outfit before it automatically released her.

Decisions decisions she thought to herself as she read and re-read the instructions. Finally, she decided to choose the setting 'full spectrum', which meant that the outfit would apply all of the effects that it was capable of. Now she had to choose the strength setting. Choices available were mild, moderate, strong, and severe. Ellie discounted mild, but couldn't decide which other setting to choose. Did she dare set it to strong or severe? Then she had an idea, she would toss two coins. If both coins landed heads up it would mean moderate, one heads and one tails would mean strong, and two tails would mean severe. Taking two coins from her purse she tossed them in the air and then looked to see how they had landed on the bed. Both were tails up.

Ellie hesitated for a moment, asking herself whether the severe setting was a wise choice. Oh hell, just do it! she thought. Turning to her laptop she entered the settings choosing to remain locked in the outfit for eight hours, and the effects to be applied at half hourly intervals. As the full-spectrum cycle of effects took about 15 minutes, she would have 15 minutes worth of BDSM effects, followed by 15 minutes rest, then 15 minutes of effects and so on until release. Finally she entered an auto-timed command in the control program so that the whole thing would commence in 30 minutes. She had half an hour to get ready. Despite trying to relax, she felt a sense of mounting anticipation and excitement.

Setting the laptop on her dressing table, she made sure that it could be seen clearly from her bed. Also she checked that the connecting cable between the laptop and the outfit's control unit was securely connected. Picking up the outfit, she put it on closing and adjusting the manual latches. This time, she used padlocks that were supplied to secure each manual latch. This meant that she would only be released from the outfit when the computer control program reached its conclusion. She also padlocked the panic button to disable it, feeling a thrill of excitement as she did so. She reasoned that there was no point in locking herself into the outfit if she could release herself at will by just pushing a button.

She was nearly ready, but a few other preparations remained. She turned to a selection of bondage items that she had purchased separately from this self-BDSM outfit. This included a large ball gag, locking wrist cuffs and ankle cuffs, padlocks and lengths of chain. Having put cuffs on her wrists and ankles, she then secured the ball gag tightly in position in her mouth. Satisfying herself that the keys to all these padlocks were safely positioned on the dressing table next to the laptop, she plugged the umbilical control and power cord into the apparatus between her legs and then moved over to the bed carrying the chains and padlocks.

Using two 12 foot lengths of metal chain she threaded the ends of one around both legs on one side of the bed. Bringing the two ends of chain together at that side of her waist belt she engaged them in the electro-latch there. She then did the same with the other length of chain securing it to the other side of her belt. Then, she took the ends of a length of chain that she had passed under her bed and secured an end in each of the electro-latches at the sides of the metal belt. Finally, using the remaining padlocks she locked the ankle cuffs to the foot-end of the chains and her wrist cuffs to the head ends of the chains thereby securing her arms and legs spread wide.

Her heart pounding with excitement Ellie glanced to where the laptop was counting down and she could see that there were some 10 minutes to go. She settled back to wait and went through a mental checklist. Had she forgotten anything? The outfit's power and control unit was plugged in and switched on at the mains. The laptop was running and was also switched on at the mains. The connecting umbilical was plugged into the apparatus between her legs. All of the manual latches on the outfit were padlocked, as was the panic button, and also the cuffs. All of the keys were out of her reach

She was well and truly locked into the outfit she was wearing, and also securely chained to the bed in a spread-eagled position. She was totally trapped and wasn't going anywhere until the computer program concluded. Ellie felt a new surge of excitement as she made a token effort to free herself, just to confirm that she was well and truly trapped. She watched the programme on her laptop steadily countdown toward zero. As the seconds ticked away, she tried to control her excitement but felt her heart pounding as her anticipation grew. This was it, she was about to have the ride of her life.

When the seconds on her laptop ticked down to 0, there was a few moments delay and then the outfit began vibrating her pussy, gently at first but then with increasing power. Ellie began to squirm and then felt her nipples being vibrated by the breast domes. With a growing sense of arousal and pleasure she continued to squirm. Then, the outfit was applying vacuum to her nipples and her clit. Gently the first but then more powerfully, her tender parts were being sucked into the apparatus nestling against them. As her nipples and clit swelled and became more sensitive, they became trapped in the apparatus sucking them in.

Ellie squirmed some more, this time in an effort to extricate her nipples and clit. But the machinery sucking at them was designed to capture and hold them securely. These tender parts were as captive as she was herself. For some minutes they were sucked and pulled before eventually being released. After this treatment her nipples and clit were really swollen and sensitive. Suddenly Ellie let out a shriek as they were repeatedly zapped by powerful electric shocks. The shocks followed a cyclical pattern in which they died away before climbing to a new crescendo.

Ellie's screams were partly muffled by the ball gag in her mouth, and her restraints prevented her from writhing and thrashing about. Now she felt real panic, this was what was meant by severe BDSM effects. How stupid she had been, she was now trapped in a horrible ordeal which she would have to endure for the next eight hours. Just as she felt that she couldn't take any more, the shocks ceased. Her sense of panic had begun to subside when she felt the dildos penetrating her pussy and her ass.

She gasped as they forced their way into her holes, wishing that she hadn't specified large dildos when she'd ordered the outfit. Once the dildos had fully penetrated, they remained in that position and began vibrating. Slowly at first but with increasing intensity they vibrated. Ellie's panic reduced a little as she became more and more aroused. She realised that she was going to cum soon and when she did she would cum very hard indeed. The vibrations increased yet further and waves of orgasms engulfed her. She'd never had so many in a day. She shrieked as loud as her ball gag allowed as her body twitched and trembled. Finally, the vibrations ceased. The dildos withdrew from her holes and she was just thinking that now she might have some respite when they penetrated her again. Instead of remaining inside now they began rhythmically moving in and out.

The movements were slow at first and quite enjoyable, but then they slowly began to pick up speed. Ellie's level of arousal was climbing once more and she knew she was going to cum again. As the dildos gathered speed Ellie shrieked louder and louder, such was the intensity of the orgasms they generated. Faster and yet faster they sped in and out of her holes. This was all too much. She thought she couldn't take much more of this, but she had no choice. She had chosen the 'severe' setting for the BDSM effects and so the dildos were pounding her holes at lightning speed.

Eventually, the dildos withdrew from her holes and fell still. It was a rest period. Ellie was thankful for the respite, but she didn't feel able to rest. She made another attempt to free herself but she knew that it was futile. She was well and truly trapped in this fiendish BDSM outfit and she couldn't escape until the computer program released her. What a fool she had been to choose the severe setting. How stupid it had been to give herself eight hours captive in the outfit.

Ellie lay trying to regain her self-control. Her emotions were running riot. The situation that she had put herself in was frightening and yet at the same time strangely arousing. But in spite of finding the situation strangely erotic, Ellie was very worried that she couldn't cope with it all. The ordeal that she had just been through was just the first episode. She had a further 7½ hours locked in this outfit and the computer-controlled outfit would deliver a further 15 episodes of BDSM effects before that time elapsed. How on earth was she going to endure another 15 instalments of what she'd just been through in the last few minutes? The more she thought about it the more scared and horrified she was.

Over the next few hours the outfit in which she was trapped repeatedly applied its BDSM effects to her most intimate and sensitive areas. She was forced to cum numerous times but she was wickedly tortured as well. Ellie realised that she had no choice but to wait for the eight hours to elapse, when the computer program would terminate by instructing the outfit to release her. Occasionally, she looked across to her laptop where she could see the remaining time counting down.

Eventually, a glance at the laptop told her that there were just a few minutes remaining. Thank goodness she thought I'll soon be free. Then, as she watched the screen changed from its usual appearance to an ominous blue colour. Ellie realised that her laptop had suffered a serious crash. Her concern mounting she hoped that despite this the computer program governing the outfit she was locked in would still instruct the electrically operated latches to unlock her. She noted the time on her bedside alarm clock and waited.

15 minutes later, it was clear that the laptop had frozen as it crashed and wasn't going to automatically restart. There was also no sign of the computer program for her outfit releasing her by operating the electric matches. Then as her sense of panic and terror escalated, the next round of BDSM effects commenced. Ellie dissolved into tears and sobbed uncontrollably. She felt emotionally and psychologically drained as well as physically exhausted. As the BDSM effects ramped up she shrieked ever louder, partly in response to the intensity of them but partly because of her sheer terror at her situation.

During periods of rest Ellie tried desperately to get her emotions under control despite fearing that she might lose her mind altogether. She tried to reason through what the possible outcomes might be for her. She had booked annual leave to follow on from this bank holiday weekend. Therefore, she wasn't due back to work for another 10 days or so. Also, she'd deliberately avoided making any social engagements so that she would have private time to play with her new toy. As if that weren't enough her parents were on a month-long holiday in the Maldives. Basically, it was entirely possible that none of her family or friends would choose to try to contact her or make an unscheduled visit during the next 10 days.

That realisation only served to fuel her panic and terror. She remembered reading accounts on the Internet of people who had become trapped in self bondage and who had died of dehydration and starvation before being found. Of course one reason why she'd locked off the panic button and locked the manual latches on the outfit was her firm expectation that the control program would release her by operating the electric latches after the allotted time.

By padlocking the manual latches, and the panic button and chaining herself so completely to the bed with all the keys out of reach she had effectively closed off any chance of extricating herself in the event of a computer failure. She had been the architect of her own doom. By now it was late evening but Ellie realised that she was unlikely to get any sleep. Each episode of BDSM effects was separated from the next by a mere 15 minutes of rest period.

The next day came and went, as did the one after. It had become the most horrible nightmare that anyone could imagine. In fact it's doubtful that many people could possibly imagine what Ellie suffered. Because of dehydration her pussy and her ass hole ceased to produce their natural fluids, so that penetration by the dildos became an unspeakable torture.

Occasionally, driven on by the torture that her most tender parts were getting from the BDSM outfit, and her horror at the predicament she had put herself in Ellie struggled in vain to escape from her bondage nightmare. But all of her struggles were utterly futile because the BDSM outfit that she was so comprehensively locked into was designed and engineered to keep its wearer totally captive until it was unlocked.

The fact that the BDSM outfit subjected her body to torture every fifteen minutes meant that she was becoming more and more exhausted. Each time she tried to snatch a few moments sleep, she was rudely awakened by the BDSM effects that it delivered. Also preventing her from sleeping was the psychological trauma caused by the nightmare scenario she had locked herself into. Ellie was convinced that she was going to die a horrible and agonised death before anyone came to rescue her. This prospect was more than she could cope with and each time she thought about it, she felt overwhelmed by panic and terror. By the third day she had lapsed into near unconsciousness.

Then suddenly, she became vaguely aware that there was someone in the bedroom with her. Startled for a moment, she felt a huge wave of relief when she realised that it was her sister Ruth. On a whim Ruth had decided to make an unscheduled visit and had let herself in with her key. Seeing Ellie's car on the drive and her handbag, purse and keys on the dining room table had aroused suspicions. Entering the bedroom she had been utterly shocked when she saw Ellie's self-imposed predicament.

Ruth unfastened Ellie's ball gag and asked her what on earth was going on. But Ellie's mouth was so dry and her tongue so swollen that she could barely make a sound, and that sound was unintelligible. As Ruth struggled with the various padlocks, Ellie sobbed uncontrollably, hugely relieved that she wasn't going to die after all. Wisely, Ruth telephoned for an emergency ambulance and soon Ellie was on her way to hospital. She required several weeks stay in hospital being treated for her physical trauma, and a year or so later she was still receiving psychological treatment for Post-Traumatic Stress Disorder (PTSD).
