It was early, nearly half an hour before any classes would be starting as Emmeline made her way across campus. The sun was just clearing the horizon and little birds were singing merrily, but the young girl that hastily crossed the meticulously landscaped lawns looked uneasy, frightened even.
Emi had woken not in her bed that morning, but lying in the grass behind her dormitory building. She had been completely nude, covered in…she didn’t even want to think about it. Thankfully the clothing she had been wearing last night had been scattered around the immediate area. She gathered everything she could fine and hastily redressed before making for the gymnasium. She knew that there would be no way to avoid her peers if she tried to get up to her 5th floor dorm room with everyone milling around, preparing for class, but the showers in the locker room should be blessedly empty this early in the day.
Her mind raced as she pushed through the dark blue double doors and slipped into the early quiet gym. What the hell had happened? Had she been drunk? Drugged? The one time in her young life when Emmeline had any alcohol had ended in rape, torture and humiliation. There was no way she would have willingly gotten inebriated, and none of her new friends had shown any signs of sinister intentions.
She shook the train of thought from her head though, not sure she really wanted to know the truth. She was practically trembling with fear when she reached her locker. She pulled out her gym clothes and placed them on a nearby bench where they were soon joined by her rumpled school uniform.
With a nervous glance over her shoulder she slipped into the showers, suddenly plagued by the feeling that someone was eyeing her naked, vulnerable form. No one else was here this early though; she was clearly just being paranoid. Forcing herself to turn her back to the locker area she turned on the shower and let out a sigh of relief as the warm water washed over her trembling body, soothing her physically even if it did little to ease her mind.

Destra was sitting rather comfortable in her pocket dimension. She had been flipping through the channels, when a young girl had caught her attention. Her tail flicked anticipating, as she watched the somewhat frightened girl dress and run across campus. The girl apparently had encountered one of the more savory inhabitants of the university. Reaching what she assumed was the gym. The girl began to undress unknowingly being watched. Destra watched as the girl reveled her bodies’ charms, and curves.

She couldn't take it any more she had to play with this one. Using her pocket dimension, Destra appeared in a remote corner of the locker room. She could hear running water, which meant the girl was in the shower. Perfect I'll just make an alteration to her uniform. Destra stopped herself from walking out into the open pinching herself. Closing her eyes she would take on her human form. Her orbs opened again to reveal their hazel color.

She was now wearing the standard outdoor uniform. Her bosom seemed to stretch the fabric of the tucked in white tea shirt. The short blue gym shorts revealed her slender thighs, and if she bent over the curves of her bottom. Walking over to the clothes pile heaped on the floor. Desera could still smell the scent of sex coming off the girl’s uniform. Her hazel orbs looked over to the girl’s outdoor uniform, and the regulation white bra, and panties.

Desera got a rather wicked grin on her face. Waving her hand over the clothes a few changes would be made. The bra was replaced with a demonic one. It looked exactly the same, as the one she had replaced it with. The panties though while outwardly looking the same. Inside where the girl’s sex would be place, was a phallus like protrusion. The girl would have no choice to wear it. It was either her new pair of panties or no panties at all.

Desera would walk outside to the gym, since it was the first class of the day. The activities would need setting up. Walking over to the now open supply closet she walked in, and began locking around. She had never set up the gym before, and looked rather lost.

Emi moaned softly as the steaming hot water flowed over her luscious curves, washing away whatever unremembered torments had befallen her the night before. She closed her deep blue eyes, the world slipping away as she let the heat relax her. Her delicate hands began to caress her soft, flawless skin.
Unbeknownst to the young student the last lingering effects of a powerful alien aphrodisiac still pumped through her veins. Not enough to drive her mad with lust as it had the night before, it still made her body far more receptive to lustful thoughts that she might have been otherwise.
She bit her lower lip moaning as her fingers teased her small pink nipples into stiffness. Her pussy quickly became moist as she allowed her mind to wander back to last night, wondering which of her classmates she’d been with. There were any number of gorgeous young woman who’d flirted with her during her short time at the school so far; being an all girls school, she figured it was only natural that the student body was more…experimental than their coed counterparts.
Her slender fingers were just beginning to tease her pussy when she heard the door upstairs open and several sets of footsteps enter. Jolted out of her reverie Emi quickly turned off the shower and returned to her locker, pulling out a fluffy white towel and quickly drying her lovely body.
She reached down and grabbed her panties, but practically froze when she noticed the phallic thing inside. She was understandably confused; she immediately recognized the panties for what they were, but was baffled as to why they were with her things instead of her regular under things. She blushed. It must be whoever she’d been with last night, teasing her. She went to put the naughty panties back into her locker, prepared to go without, but hesitated. Who would know if she were to wear them…?
She made up her mind quickly when she heard the first of her classmates come down the stairs. Delicately she slipped her slender legs into the garment and slid it up her thighs. She moaned, careful not to make too much noise as the smooth shaft penetrated her tight little cunt. She giggled softly as she pulled the panties up snug against her sex, wriggling slightly as she enjoyed the sensation. Next she donned the seemingly normal bra, which strained to confine her ample breasts. Most of her class was in now as she pulled her thin white tshirt over her head. It was a bit snug around her chest, and the shadows of her nipples were quite clear to anyone who cared to glance at her. The tight blue shorts came next, hugging her hips and firm little bottom tightly.
Her uniform complete, Emi headed back upstairs, weaving through the crowd of half-dressed girls quickly, before she could think better of her little game.

The instructor was standing there with her clip board. Occasionally she would look up to see who was coming, and going. The inside of the gym was empty with the perfect weather. The instructor looked at her watch, and then at the group of girls standing in front of her. "Okay girls today we will be going outside, so if you would all kindly file to the outdoors field."

The students would listen to the instructor, after all none of them wanted to be sent to the basement. Once outside some of the girls looked rather uncomfortable at the activities set up. There was the traditional vaulting horse set up. The students were told they be running the full length of the track and field course. Then there was to be a game of volleyball.

The one thing making the girls uneasy was set to the side. It was a two feet piece of rope with a rather large knot every four inches. That made a total of eight knots along the entire length. The knots looked big enough to be felt, or push anything deeper into them. The rope itself was four feet in the air, making it a rather uncomfortable height, if one was to walk with the rope in between their legs. Oddly enough there was a girl just finishing tying the other end down. The girl checked to see how tight the rope was by plucking it like a guitar string. The rope vibrated back and forth in a small side to side pattern.

Happy with the set up, the girl would run back to the rest of the class. Her bosom bouncing up and down, as the white tee shirt tried to restrain them. The girls short cut silvery locks were only follow slightly behind her. Stopping to the side of the instructor, she turned to face the class. "Instructor the punishment station is finished being set up." The instructor just nodded her head.

"Class this is Desera she's with a later gym class. She'll be making up a class she missed with us today. From what you heard we have a special treat for those few slackers, and mess ups. Anyone who isn't given a hundred percent will find themselves walking the length of the punishment station." The instructor was apparently looking for a volunteer for a demonstration.

Desera in the mean time had gone into the crowd of school girls. Now well concealed, she decided to give the girl she decided to play with some motivation. The bra would begin to message her orbs in a slow motion. It was nothing serious, but it couldn't come at a worse time. The phallus in her channel also activated. Apparently it had a time delay to it to choose and turn on now. The vibrator in the girl’s channel would begin to slowly churn her insides up.

"Ah Ms. Whitaker you seem to be in an anxious mode today. Please come here, and turn to face the class with your hands behind your back." The instructor produced a set of handcuffs from some place on her person. "Now don't be shy this is just a safety precaution, so you don't hurt yourself." The instructor waited for her to approach the front of the group.

Emi followed her peers and instructor out onto the sunny sports fields. She seemed to be controlling herself quite well despite the thick, false shaft sitting snugly inside her moist pussy, but still she was careful to keep towards the back of the crowd. Her games teacher was notoriously strict; she seemed to love handing out detentions whether they were deserved or not, so Emi wasn’t took keen on drawing her attention.
The activities for the day were all pretty standard, but Emi was already regretting her decision to impulsively don the strange underwear. She was doing alright while standing still, but how would she control herself while running, jumping and doing all the other physical activity that was unavoidable.
And then there was that strange rope contraption…Numerous theories as to what it could be raced through her mind, none of them entirely pleasant, and she could tell that her classmates were having similar thoughts. Her mind was derailed for a moment, however, when Desera ran over to join the class.

In her heightened state of arousal Emi was…perhaps a bit more appreciative of the bounce and jiggle of the silver-haired stranger’s breasts, and the way they strained against her thin white t-shirt, as if they might burst out any second. She quickly found herself picturing the strange girl nude as she ran and a soft blush colored Emi’s cheeks.
Emi’s attention turned back to the “punishment station” along with the other girls’ when their instructor revealed its purpose. They all simultaneously tried to look as innocuous as possible, no one willing to meet the authority figure’s gaze.
Then, of course, her demonic undergarments kicked in. Emi nearly gasped when the bra began to fondle her soft, supple breasts. She looked down, fully expecting to see the hands of one of her classmates grasping her flesh, but there was nothing.
The vibrator’s sudden low buzzing was too much, and she let out a little squeal of surprise, as if someone had suddenly pinched her, and immediately felt her teacher’s attention zero in on her.
Reluctantly, Emi slipped away from the group and walked forward. She did as instructed, turning to face the tightly knit group of girls and clasping her delicate hands behind her. Several of her peers giggled when they saw her stiff nipples straining against her t-shirt’s thin fabric.

Destra watched as Emi was handcuffed. With her hands behind her back the girl’s chest was put on full display. The showing of erect nipples told her that the clothes were working. Not only was that but the girl’s sexual energy beginning to flow. "Okay Ms. Whitaker you're going to walk over to the punishment area, and place the ropes in between your legs. You're then going to walk down the entire length, and don't try avoiding the knots. Avoiding the knots means you turn around, and walk it again. Ms. Sanchez please assist Ms. Whitaker to and onto the punishment area."

Desera asked if she had to, and only got a quick snap about joining Ms. Whitaker on the device. The girls would watch carefully, as Desera and Emi walked over to the punishment area. "Okay let me help you onto this thing. I think your instructor is a sadist to think of something like this." Some of the girls would giggle at the girl’s predicament, while others would blush as the device purpose became clear.

Emi obediently made her way over to the bizarre device, though her steps were slow and obviously reluctant. When the silver-haired stranger approached she blushed anew, but her words were somewhat comforting. It didn’t make the situation any less cruel or humiliating, but knowing at least one person sympathized with her was clearly appreciated and she gave Desera a small, shy smile.

Mounting the high rope was difficult. Had the other girl not been there to help her she may have topped over. It wasn’t much of a relief when she was in position however. The knotted cord would have been snug against any of the girl’s nether regions, but it was particularly tight against poor short Emi.

Biting her lower lip she slowly began to make her way along the cord. Each thick knot stimulated her clitoris as they rubbed across it, but it was almost worse when they forced the buzzing vibrator deeper into her tight little pussy. Her fair cheeks were bright red with embarrassment and she practically trembled as she slowly crossed the rope.

A devious smile crossed the instructors face. She was enjoying the reaction on the other girl’s faces. Most of them were a bright red color now, while some of Emi's admirers were fantasizing of having the girl to themselves. Desera on the other hand was the closest with the best view. This of course made the others jealous. Desera's checks were a pink color thinking about what it felt like to walk between the knotted tight rope. The way it would feel against the crotch, as each knot ran under it.

Time to spice things up a bit. Emi wouldn't notice due to her back being turned, nor would the others due to their distance. Desera's hazel eyes now had a red ring around them. Emi would suddenly get a shot of lust, and a vision of the Desera in her position. Only Emi was on the other end holding the rope, and occasionally causing the rope to rub in deeper as Desera passed over a knot.

The vision and shot of lust would only last a few seconds, and then pass as if nothing had happened. Desera's eyes had returned to normal by then. Half way across the rope, Emi would feel her peaks being twisted by the bra. The vibrator in her channel would speed up slowly, to a new constant speed the girl would need to deal with. Desera just stood there waiting to see the girl’s reaction, to her sudden change in conditions.

Emi couldn’t bear to look back, to see the way her classmates were looking at her. It took all her concentration to keep from crying out with lust. In a way she was glad her wrists were bound behind her back - she wasn’t sure she would have been able to resist the urge to tear away her clothing if they weren’t.

When the vivid images of Desera standing in her place flooded Emi’s mind the timid young girl froze, gasping. She started, mouth agape, as her mental image of herself cruelly yanked up the rope, causing the silvery haired girl to moan. She’d never fantasized about dominating another girl before, but the sight of Desera moaning and writhing on the rope was incredibly invigorating. She wanted to reach out and touch the girl but when she moved her arms the handcuffs clinked, bringing her back to reality.

She briefly glanced over her shoulder, worried that someone had noticed her sudden lapse of attention, but when she found herself looking into Desera’s gorgeous face she quickly whipped her head back around, struggling to concentrate. She’d barely moved an inch before the succubus’s new torments kicked in. She couldn’t help it - she cried out with pleasure, her head falling back slightly as the assault on her senses was suddenly ratcheted up a notch.

Her breathing was becoming labored as she gathered every ounce of her strength and forced herself to continue, though she couldn’t quite silence the steady stream of quiet moans. She blushed, knowing that Desera would be able to hear her lusty cries, though she hoped against hope that her teacher and the other students couldn’t.

Desera indeed hear the girls every lustful moan. Oh my so easily aroused. She had to keep up the act of being embarrassed though. The other girls and instructor couldn't hear her though. For all intents and purposes, the demonstration was going better then the instructor had hoped for. Desera knew this better then the instructor did. She could feel sexual energy coming from some of the girls in the group. Apparently they had been aroused by this demonstration.

Emi on the other hand was radiating sexual energy. Desera was inwardly smiling, as the girl looked back at her and suddenly turned back around. She could see the girl was having problems continuing. "What’s the matter Ms. Whitaker is it too much for you to handle? You could all ways just cum, and walk the rest of the rope!" The instructor called over to the two of them.

Though they couldn't hear Emi’s lustful moans. They could tell by the way she was hesitating the further she got down the rope. It seemed they were waiting to see if Emi could finish before she climaxed, or if she climaxed before she reached the end. "Come on your all most there just a bit further." Desera cheered Emi from behind hopefully motivating the girl along.

Emi glanced over her shoulder again, glaring daggers at the coach as she mercilessly taunted the poor girl. The woman had been cruel in the past, but this was horrible even for her. This had to be violating countless school rules, but she knew perfectly well that her students feared her wrath enough that none of them would dare report her.

Emi gave Desera another small, shy smile, clearly grateful for her encouragement before she turned back around. Of course after those oddly vivid fantasies she found herself unable to separate her warm feelings for the silver-haired beauty from her appreciation of the girl’s gorgeous body. As the cursed bra continued to twist and tweak her nipples she couldn’t help but picture Desera’s hands doing it…

No, no! She had to concentrate. Emi was determined not to give her sadistic teacher the satisfaction of seeing her cum. Her bright blue eyes flicked back down to the rope. Six more knots. She was almost done, if she could just control herself for the last stretch of rope…

Taking a deep breath, Emi closed her eyes and started forward again, slightly faster now. “Nnnn…Nnnn….Nnnn!” She moaned, letting out a little whimpering cry as each of the thick knots ground against her throbbing clit and pushed the buzzing vibrator deeper into her dripping as it passed underneath. Three more…two more…one more! When she finally passed the final knot Emi shuddered and slumped forward slightly, breathing heavily.

The instructor frowned at the prospect that Emi had made it all the way through. "All right slackers you've seen the demonstration. Now get on the field and start running laps. Ms. Whitaker I expect to see you with the rest in one minute!" The instructor then blew her whistle, and set her watch to one minute.

The other students began to run laps around the track, and field. Desera knew the girl had climaxed. It might have not seemed so physically, but her sexual energies told the tale. Desera ran over to the end of the rope holding Emi up. "Let’s get you off this evil contraption." Getting Emi down Desera let her rest against her shoulder for a bit. "Are you okay? Do you think you can participate in the rest of the class, after what just happened?"

They could say Emi had passed out from physical exhaustion, or even dehydration. The bra and panties would return to their normal teasing level before the rope. Desera's head suddenly shot up hearing a whistle blow. "Hey you two a minutes up, get a move on or it’s the punishment station! Get those handcuffs off of her." Desera suddenly caught the handcuff keys. Leaning in to see what she was doing, Desera's ample bosom would press against Emi's

Emi would suddenly feel that she could move her hands freely now. "Come on before we both have to walk that thing." Desera picked herself up, running to the instructor and handing back the handcuffs and key. She then proceeded onto the track with the rest of the girls. "Ms. Whitaker get a move on, or do you enjoy walking the punishment station?"

Despite the rather unpleasant situation (well, socially unpleasant, physically it was an entirely different matter...) Emmeline couldn't help but let a faint smirk pull at the corners of her full, soft lips. Without even looking back, she could tell that her instructor was quite angry with her. The young teacher's usually harsh voice was even sharper now. It would come back to bite her many times before the class was over, Emi was sure of that, but for now she had won.

Her heavy breathing gradually slowed back to normal as Desera helped her down from the rope, though until it did her large, perky breasts strained against her thin t-shirt, her diamond hard nipples casting darks shadows on the fabric under the bright morning sun.

"I...I think I'll be fine. I'm sure she'll find something even more awful to make me do if I try and get out of class." Emmeline said, giving the silver-haired girl a shy smile. It had been obvious even before that she was gorgeous, but now that they were so close Emi was having a very difficult time not staring at her magnificent body.''

Emi blushed brightly when, without warning, Desera wrapped her arms around the petite girl in order to unlock the handcuffs. She almost moaned as their soft, full breasts were forced against each other. She briefly wondered why she hadn't just gone behind her to unlock them, but it felt so nice that she didn't particularly care.

When Desera ran off Emi caught herself staring at the other girl's finely sculpted rear, which her tight blue track shorts showed off quite nicely. Their coach's final warning snapped her out of it and the petite girl quickly ran to join the rest of her class.

The run would go by without incident for the most part. Emi would hear the giggles of girls as they passed her, but it seemed everyone was running fine for the first few laps. The instructor was watching them like a hawk, and seems to notice any small slip up. A few of the girls had been sent to the punishment station. Some of them were climaxing not even half way through. Desera would send Emi a little vision every time she was behind the girl, and Desera knew no one was going to notice her eyes.

The vision was the same one over, and over again of Emi having intercourse with Desera on the track and field during a moonlight night. The visions seem to last longer and longer every time Desera was behind her. The whistle would blow, and the girls would line up again. Their white shirts stained with sweet, revealing some of the girl’s ample bosoms. This was especially true for Desera. "Okay girls it’s time for the vaulting horse. Line up and be ready for your turn." The Instructor seemed to have her eyes focused on Emi.

The bra and panties would kick in again. There speed increasing to what it had been during the rope walk. Instead of twisting Emi's peaks the bra began to suck on them. Desera was standing two girls behind Emi for this event. When it was Emi's turn a vision would hit her, just as she hit the trampling. The vision showed was of her tied to the horse, while Desera was whipping her. The vision lasted long enough, for her not to know where the horse was.

When she heard the orgasmic cries of her classmates as a handful of them were sent to their own sessions on the punishment station, Emi felt somewhat...vindicated. She smirked softly to herself when she ran past a blond girl in the throws of an orgasm with nearly ten knots left to go. Even as she eyed the shuddering girl the increasingly-familiar mental image of herself and Desera locked in the throws of ecstasy came to her mind unbidden. Her silvery hair glittered in the moonlight, and her gorgeous body glistened with sweat. She’d never had this much trouble controlling her fantasies before, and while it was somewhat worrying it was difficult to try and not picture such an arousing scene.

The harsh, sharp sound of their teacher’s whistle broke her concentration and brought her back to reality once more. Emi followed the rest of the girls over to the vaulting horse, her bright blue eyes drawn like a magnet to Desera’s heaving chest. When the girls were ordered to like up she reluctantly shifted her attention back to the task at hand. When the bra and panties suddenly increased their stimulation again Emi gasped loudly, her slender legs wobbling slightly.

The line moved on despite her situation and she struggled to stay focused. She could feel the teacher’s eyes burning a hole through her skull and silently hoped that it was a generalized aggression, and not an indication that she could tell what was happening to the helpless girl. She bit her lip, brushing brightly as it felt like two unseen mouths began sucking gently on her stiff nipples. The last person ahead of her in line took her turn, and Emi reluctantly stepped up. Taking a deep breath she ran down the short track, and was instantly hit with the succubus’s vision. The entire class could hear Emi’s cry of surprise. She could practically feel the whip biting into her bare flesh and hear Desera’s sadistic laughter. When the image suddenly vanished from her mind she nearly crashed directly into the horse. She was pleasantly surprised when her hands shot out by instinct and lifted her petite body up and over the padded device. Her joy quickly vanished when she realized there was no way she was going to clear it - she came down with a thud just a few inches from the end of the horse. Her momentum carried her forward, her upper body falling while her hips stayed planted. She threw her arms forward and managed to catch herself and keep from crashing to the ground, but in the end she just ended up bent over the far end of the vaulting horse, her slender legs and pert little ass up in the air. She groaned, unsure of how to get down with anything resembling grace.
