“I did take one risk…”, Paul went on, both noticing and enjoying the delicious way Natsuko was already squirming, “… and added a research add-in to the Robotics studio software to apply genetic algorithms to the patterns I’ve created for you. That will enable the software to add “mutations” to those patterns, track the success of the mutations, and continually evolve how the trunk plays with you. The software’s goal is for you to have the longest, strongest orgasms possible, and it will be tireless in figuring out just what is the most efficient way to do that.”
Natsuko wasn’t sure if it was the grin on his face, or the words he spoke, but the hairs on the back of her neck were standing on end and her brain was screaming, “RETREAT, RETREAT!” Paul was about to lock her into something that would “learn” her, that could read every nuance of her arousal, no matter how badly she wanted to hide it, and would be single minded in its pursuit of turning her into an orgasm machine. She knew deep down this was a Pandora’s Box and that once stepped into would change her life forever. Little did she know just how profoundly true that was about to become.
But as usual it was the rising heat between her legs that would control her actions. No matter what her head or the hairs on the back of her neck were telling her, there was never any question that her arousal was going to pull her body into that trunk, even if the rest of her consciousness was kicking and screaming.
Paul chuckled, clearly reading her body language, and showed her just where to plug what, and how to finally ease back into position so all her D-rings lined up with the slots in the trunk. Natsuko was literally shaking in anticipation and when she felt the deadbolt style bars slide through the D-rings locking her neck, back, waist, wrists, and ankles in place. She thought her heart was going to leap from her chest.
The closest thing to a rational thought going through her head was the words, “Oh my God, oh my God, oh my God” over and over as she realized she was now completely and utterly helpless to stop this. She was at the mercy of this wicked smart new trunk Paul had built just for her, and it would have its way with her, for as long as Paul allowed it to. Behind the monitor-blindfold, her eyes were wide as saucers as Paul slowly closed the trunk, its similar deadbolt style bars sealing it shut, and went to his laptop.
“Testing 1, 2, 3 Testing 1, 2, 3 – Can you hear me Natsuko?”
Natsuko moaned into her gag, not really capable of much else besides that at the moment.
“Excellent, I’m going to run through each of your new inputs, and make sure everything is functioning properly. I can probably tell just by watching your arousal level on my screen, but I’m going to ask you anyway, so I’d like you to grunt or moan as we walk through each one just to be sure.” So began a tedious checklist that made poor Natsuko feel more like she was a rocket about to be launched than a girl locked in a trunk looking for a Friday night diversion.
…
“We’re just about an hour till midnight, and everything seems to be working perfectly, so I’m setting the timer to start at 11:00 and run a one hour cycle. If all goes as planned, and you don’t seem to be in any discomfort, it will immediately go into a 2 hour cycle, then a 4, then an 8, then 16. Factoring in your 4 hour rest period from 2 AM – 6 AM, that should take us into Sunday afternoon and I can decide then if I want to run another cycle till Monday morning or not.”
“Oh My GOD!!!” Natsuko thought to herself. “This isn’t just a small test run, he honestly intends on keeping me in here for the weekend – as long as that first time! Except now the trunk is WAY more capable of exploring every conceivable pleasure option my body has to offer!”
The first round was pretty much what she expected, all of her sensitive parts started vibrating on the lowest setting, and just as her arousal rose, so did the level of the vibrations. She fidgeted in her bonds as she came closer and closer to an orgasm, and sure enough, just as she was about to cum, all the vibrators stopped at once. She was left tantalizingly close, and utterly unable to do anything to get herself over that last little bit.
After a minute or two and just as she was starting to resign herself to not being able to cum, the vibrators started up again from the lowest setting. She tried to count how many times she was brought right to the brink before being denied, but it was useless. At first she cursed the trunk for denying her, then begged it for release, then tried to bargain with it (“PLEASE let me cum and I’ll do ANYTHING you want” and the like) and finally, she resorted to praying to God, her husband, and even the inanimate trunk that it please let her cum.
During the eighth round and just as she got to the point where she knew it would stop, it didn’t. The vibrations kept on high, and she was utterly taken by surprise as her body erupted with an orgasm even more powerful that the first one the trunk gave her. The pleasure radiated out from between her legs and seemed to engulf her body. The trunk patiently watched and waited, and only as her pleasure started receding did it slow down and finally shut off the vibrations. Natsuko was completely and utterly content and satisfied. That is, until a few minutes later when it started all over again.
The next cycle was different; she could tell that the “genetic” module Paul had mentioned had kicked in as the program started mutating itself. Sometimes it would take her to the edge, stop, and then restart on a high setting instead of going back to the bottom. Other times instead of just stopping, it would shock her sensitive parts, or apply cold to them to back her off from the edge. It was continually trying new things and measuring the results. Natsuko had wanted less predictability and Paul had exceeded her wildest expectations. Unable to predict what was coming, she was helpless to prepare for it, and became utterly and mindlessly in the moment.
About an hour and forty minutes into her two hour cycle, something odd happened. When she tried to relate it to Paul latter, she could never quite figure out how to describe it. The best she could do was to say it felt kind of like an out of body experience. Her body seemed to go on some kind of auto pilot while her mind just… checked out and seemed to float above it all. She could still feel all the stimulations being applied to her, but somehow, she didn’t mind as much. It was like she could feel it being done to someone else, instead of herself. She apologized to Paul since no matter how she tried to put it to words, it sounded like nonsense, but she assured him she felt every contradictory statement she made about it.
This out of body experience made her next orgasm even more interesting, if not more powerful than the last. From this dreamy otherworldly state, her body seemed to soundly grab her consciousness, and pull it through her g-spot to engulf not just her body, but seemingly her very soul in pleasure. It seemed to go on and on and on and when it finally subsided, she was utterly spent. As she quietly waited for the trunk to resume tormenting her with pleasure, it surprised her yet again by not doing so. She had completely lost track of time and forgotten that Paul mentioned a sleep cycle from 2 AM to 6 AM each night. As she floated in her post orgasmic bliss, she drifted off to a deep and profound sleep despite all her restraints.
The next morning, she awoke to the very pleasant ministrations of the trunk as it began its next cycle. When she finally rose to full consciousness, it took her a second to understand why she couldn’t see or hear, or move, and why she felt so damned horny. As it all came back to her where she was and why, she groaned into her gag – it was just the beginning of what was surely to be a VERY long day!
…
The next cycle continued much like the last, and that meant it was equally unpredictable as the trunk’s programming continued to mutate and adapt to Natsuko’s body. It became more and more capable of taking her rapidly to the edge of an orgasm and sustaining her there for longer and longer periods of time, without having to start and stop her stimulation. As much as she hated the rises and falls of the original program, she was positivity sure these changes were worse. The trunk was managing to drive her out of her mind with sexual need while offering her almost no respite at all. There were no rounds to try to count, just one long endless need between her legs that robbed her of all reason. She became that throbbing need and it came to define her existence. She drifted in and out of her body like this for quite some time, until something yet again new seized her attention.
Suddenly something was sucking on her nipples, and that tiny bit of new stimulation took her to an entirely new level of pleasure. It was almost as if this orgasm started in her nipples and spread to her neither regions before engulfing the rest of her. As the breast pumps rhythmically sucked the milk from her, each pull from her engorged breasts seemed to cause a spike in her long continuous orgasm.
Her body seemed incapable of stopping the orgasm as long as she was being milked. She wasn’t even sure if it was one long orgasm, or dozens of tiny ones, each happening as her nipples were vacuumed up into the pump. When the breast pump finally stopped, her body was as utterly emptied of energy as her breasts were of milk. She was sure if the trunk wasn’t supporting her, she would have collapsed into a heap.
Before she could even catch her breath, a new cycle started all over again. She moaned, she cursed, she screamed, she begged and pleaded through the gag for it to all stop. But of course, the trunk didn’t understand any of this, and wouldn’t have cared even if it could. It was a machine, all it understood was what it was programmed to do, and at the moment, it was programmed to continue trying to give Natsuko the perfect orgasm, whether she wanted it or not.
