With no clock and no cell phone for reference, Sue thought she had spent hours bound to the horse--it sure seemed like it--but she really had no concept of time. All she could do was endure the endless cycles of stimulation, from mind blowing pleasure to being tormented and teased using only the lightest of vibrations. The whole time, her position on the horse was getting more and more uncomfortable. Though not quite torture, it may as well have been given the effect it was having on her. She was at the mercy of the machines inside and outside of her as they went about their separate tasks. Pressed against her pussy, the saddle was just a relentless appliance motoring mindlessly along in its electrical duty, oblivious of her existence--slowly speed up, shutdown, pause, start again. Inside her, the squid was driven by a seemingly confused microprocessor, constantly evaluating sensor results and adjusting data, then trying again, on its endless mission to find the perfect formula to fuck her, tease her or whatever .

She tried to accept her situation like she had done on the phallus chair, deliberately trying to choose enjoyment instead of useless resistance. Her body simply had these functions and responses. Nature wants her to enjoy sex so that she will do it again and again to get pregnant and reproduce. It's just that simple, a biological program for survival of the species: at least that's what she told herself. It wasn't working. Sue couldn't just relax and enjoy herself. Searching for a way to escape was a compulsion; she couldn't just give up and be helpless.

Sue had always believed in the supremacy of the rational mind. Her will should be strong enough to master her own thoughts despite her body, but her rational mind was doing her much good now. Her body was steered by the horse, and her intellect was just along for the ride. There was no reining this horse back in. Resisting was like trying to fight hunger: your willpower can only last so long before you ate that pint of ice cream calling from the freezer. She told herself that she was the kind of person who could resist the hunger and starve herself to death if needed, yet she ultimately knew that she would give in again, just had she had done so many times already.

She wasn't like Cindy. Overt sexuality was not part of her self-image or a quality she valued in others. She was a scientist and scholar, a woman of intellect and rationality. She did not resort to sex as a means to an end. Counterculturally, the Nuymean concept of sexuality was not like that at all. The Nuymeans seemed to simply expect overt sexuality like it was an ordinary typical feminine quality. Despite an extensive vocabulary, there was no Nuymean glyph for promiscuous, slut, whore or and similar world which passed judgment based on sexual behavior. She was having a hard time getting her head around the idea. Why? Perhaps the answer was part of their test. 

The nettle cream Charlie rubbed into her breasts and pussy was doing its job. Her swollen nipples were driving her crazy with itching and tingling sensations. The constriction of the twine loops further exaggerated the effect. She had learned to minimize her movements to avoid swinging the weights. Her nipples were slightly numb at this point from lack of circulation, but the numbness itself was also a stimulating sensation. Her breasts, as a whole, felt relatively heavy and swollen compared to normal. She had never thought of them as such a powerfully erogenous part of her body before. She was also very conscious of how they were fully on display even though there was no one to see her. She couldn't take her mind off them, but mostly, she craved touch. If only someone would rub her breasts or suck her nipples...it would be sooo nice.

Her legs were aching from the tucked up high position while her arms were getting sore from bracing against the neck of the horse to keep upright. She was nearing the point of exhausted collapse. The gag was a mercy in a way. Her jaw ached, but not having the option of speech did take away some of the potentially more embarrassing possibilities. The herbal anesthetic qualities of the rubber, if that's what it was, completely deadened her tongue and even affected her vocal chords as well. It was like a giant sore throat lozenge her tongue couldn't dissolve. She certainly would have been screaming for help or begging for release long ago without the steadfast mouth plug, and she suspected that Charlie and Martin suspected as much and had deliberately left her on her own so that they would not be tempted to offer her any relief. Maybe the gag itself was just a precaution on their part to keep her from creating a disturbance.

Sue had lost track of her climaxes. The flood of sensation was too distracting. The squid seemed to be in a ten minute wait right now, but the saddle was ramping up again, like clockwork, towards the next wave crest in the cycle. The vibrations were slow, deep and throbbing. Their strength put the vibrator wand she usually used to shame. She couldn't help squirming, yet again, with equal futility and equal resulting torment from the swinging weights. Even after so many repetitions, the urge was still impossible to fight. Her biological machine was relentless too, in its own way. In fact, she might be responding more strongly over time. Maybe her body was being conditioned just like the mind could be brainwashed; it was hard to tell.

She wished the squid would engage. When it was dormant, she could barely tell it was there anymore. Nevertheless, the persistent throbbing of the saddle was driving her up the ladder of arousal, and she was already a little breathless. She kept pulling at her wrists and straining to free her legs, pointlessly. She needed a break from the horse. Each orgasm was increasingly more exhausting. The warmth of the remaining hot lube still seemed to help restore her muscles between climaxes, but it was not enough.

The pressure of the cupped metal "horn" of the saddle pressing into her pubis was firm, unavoidable and quite relentless. As the motor hummed away, she crossed the inner point of no return where another climax became all she wanted and all she could think about, no matter how exhausted she was. In fact, she was starting to get a little frantic that she might not climax in time. She knew the cycle of the saddle intimately now. It had a steady rise in intensity, followed by a sharp fall, only to pause then start over again. The first part of the cycle was very gradual and slow yet the apex at the end of the cycle did not last long. She was nearing the end of a peak now and was still a ways from climaxing. She had missed reaching climax a couple times before under the same circumstances, and it was maddening. It left her stuck and thoroughly horny without enough sensation to go over the top. She was forced to endure a slow tease and cool down until the squid engaged or the next cycle of the saddle started. The sharp drop in vibration from the saddle was clearly intentional, and she hated the saddle designers for it.

She tried grinding her sex into the metal horn of the saddle for all she was worth before the peak ended, desperate to cum. That did it. The orgasm started, but her world was not rocked. The saddle was already subsiding before she was done. Sue wanted to scream in frustration, but still finished several light contractions. It was enough, technically. The horse slowly tilted back upright. She had her nine. Uneventfully, the metal bands retracted, and her hands were free. Sue tentatively pulled a foot loose, and it came free at last. Her arms and legs were stiff and sore. She just sat on the horse, awkwardly hanging with no other support for her feet, waiting for her circulation to return to normal.

As she was recovering, the next cycle of the squid started with a slow vibe. The floor was just a blur without her glasses so she could only wonder what the remote said, down there somewhere on the floor. The head of the squid swelled and started pulsing like it was a beating heart. It felt amazing. Yet again, the squid had calculated some new technique to experiment with on her. To her surprise, there was a separate sensation--one tentacle was feeling around.

Still, she had had enough so started to get off the horse. She found the foothold on the side that she had used to mount the horse originally. As soon as she lifted up and started to swing her other leg over the horse, a sharp electric shock from the squid ripped through her. It hurt like hell--like a bee sting to the cunt. She dropped back onto the horse to regain her bearings, feeling faint and close to passing out for a few seconds. As soon as her ass was back in the saddle, the pain stopped.

She held still for a minute carefully assessing her predicament. Should she try to get off the horse again? Now she remembered the warnings on the remote before she had dropped it, "Must remain in seated position until program completes." She was in ride mode still. Fuck, she was still trapped on the horse and would need cum again while still seated.

There was no good position to sit on the damned thing without using the footholds. Without her feet locked in, they were just hanging and pressure on her crotch was heavy, almost painful, from the awkward position. She had already sat that way longer than she should. Leaning forward towards the neck allowed her to keep her balance but pressed her vulva into the saddle plate. She knew better than to put her feet back in the holds. She would just need to wait it out. Now that her hands were free, she tried to pull at the gag with one hand, but it was hopeless. She couldn't even get her fingers underneath the straps well enough to get a good grip. She would need to get away from the horse for it to release.

She turned her attention to the weights on her nipples hoping to relieve the pain, but the twine was just a blur, way too close for her uncorrected vision. The knots were too small and tight for her to loosen them by feel, especially with only one hand. She tried pulling at a loop, but they were tied with some kind of slip knot and the pulling just caused more pain. She tried working at them for a while, hoping to peel the twine off, but her fingernails were just tearing up her nipple so she stopped. Sue was still shocked that Charlie and Martin had put them on her. They didn't seem to be playing domination games with her, or they would probably have stayed or done a lot more to her if that were the case. They were trying to follow a plan with her. It was like they were coaches getting her ready for the big game. They didn't ogle her or grope her. She might even have called them respectful.

Neither of them had commented on the Nuymean glyph on her chest, but it was so obvious that she was certain they saw it. They probably knew more about what it meant than she did. The serious tone of the training implied they were preparing her for something, but it was no use trying to figure it out now. She had to get the guide book from the annex and would need to talk with them.

Sue lifted the weight hanging from her left nipple with one hand. It felt like one of the brass weights used on a balance, probably one from right here in the geology workroom. She wasn't sure how many ounces it was, but it was damn heavy enough! If it were any heavier she wouldn't be able to stand it. Immediately her lightened nipple reacted with pain from a slight return of circulation. She slowly lowered the weight and winced at the returning constriction. She was trapped in a different sense now--no matter what she did, removing the weights would be painful.

The whole time she was trying to relieve her nipples, the squid was teasing her ruthlessly. The vibrations were just barely there. Enough that she knew she was still required to remain seated, but not enough to help her reach climax. Instead, it kept her strained muscles tensed and uncomfortable as the minutes ticked by at a snail's pace. Finally, the saddle started to vibrate slowly but deeply like it always did, right on schedule.

The squid started to throb with deeper vibrations too, but still continued to pulse its head, just at a different pace. It was almost like it was expecting assistance from the vibrations of the saddle. No...it was trying to synchronize with them! The squid was adjusting to match the frequency of vibration from the saddle. When it finally did, the sensation almost made her cum immediately. It shook her whole body from crotch, pressed firmly on the saddle, up her spine, to the back of her neck. It didn't last more than a few seconds though. The squid moved its oscillations slightly off cycle from the saddle. The effect was brutal--the orgasm switch was flipped back to off immediately. It seemed to setup a third oscillation from the squid to the saddle horn and back. The frequency was too high. It felt like her whole sex was quivering but unable to do anything else. Her electronic lover had tuned into the fingernails-on-the-chalkboard version of an oscillation, forcing her muscles to tense without any pleasurable feeling.

The saddle continued slowly ramping up with faster and stronger vibrations, but in the meantime Sue was still gripped by the contradictory vibrations of the squid. It was like orgasm constipation. It reminded her of white noise where one frequency is matched in an opposite wavelength to existing sounds in order cancel them out. She needed to cum so badly, but couldn't get it to happen. Even grinding into the horn didn't help bring her closer to the edge. The squid had found a way to hold back her satisfaction. Compared to the saddle's big motor, the squid was tiny, yet it was holding its own, locked in some kind of duel over the ownership of her pussy. She desperately wanted it to end so that she could, hopefully, somehow, finally, GET OFF THE FUCKING HORSE!

The quivering increased to the point where the sensation was starting to feel more like a relentless tickle. Sue wasn't laughing. She didn't want to experience this feeling ever again; it was that unpleasant. As the saddle continued its mindless ramp up, the squid suddenly started shifting its frequency to match. As it moved closer and closer to a unified rhythm, her whole body shivered uncontrollably in reaction. The squid had timed the vibration to perfectly match the frequency of her own contractions while still accounting for the vibrations of the saddle. Her whole body vibrated like a guitar string with all resonances in unison.

She pitched and rolled back and forth on the horse then gripped it tighter with her legs trying not to fall off. It made no difference to what she was feeling. Her body had claimed control. Suddenly she felt the pressure of that single roaming tentacle as it continued its search. It stopped the seeming random searching, poked out of her and hooked her clit from the inside. It massaged her magic button with a surgeon's precision. She shook to a climax that ran from her toes to the top of her brow. The throes of pleasure ran up and down her body over and over again. For the first time, she felt her own juices squirt out of her vagina and plunge her nether lips in chemical heat as the depleted hot lube was ejected in a final eruptive burnout. Sue leaned back, arching her body in ecstasy, conscious of nothing but the pleasure throbbing through her.

By the time Sue realized she was slipping, gravity had already won. Her flailing hands found nothing to grab. She fell backwards off the horse with a complete lack of grace but no lack of velocity. She lay stunned in pain and pleasure on the tile floor, helpless, continuing to cum violently, as the roaming tentacle kept tickling her in that most right of places.
