Green With Desire

Hello and welcome to my story of delightful salacious fun. It is a long one so I hope you are sitting comfortably. Some notes before we begin:

• This is set in a world where super-human abilities exist. These abilities are used to perform BDSM acts.
• All characters are 18+.
• The story does contain dub-con (that transitions to full consent), humiliation and bullying.

Enjoy!

Morning Class

Vulcan University sits, as one might expect from the name, atop an active volcano range. Whilst some may think that this is for the endless supply of geothermal energy to fuel its astronomical electricity bill they are only partially correct. It is for the safety of the world at large, no one wants to live in a blasted hellscape after all. Those that attend here are the next step of humanity, possessing as they do abilities far beyond that of any mere mortal. Gathering such a large group of powerful individuals in one place is a risk, when they're all freshly minted adults eager to enjoy theirs and others new found freedom in life it is a recipe for disaster...

---

As soon as the lecture ended Helena Micanicos made a beeline for the door. Unfortunately given her bad eyesight she had to sit by the front which meant walking out past everyone, including her. Helena wasn't disliked but as a shy introvert she also had no friends to speak of so, when the woman who had decided to take it upon herself to make Helena's life miserable struck, there was no one to defend her. The university imposed a uniform to help keep everyone in line and Helena's mother had always told her that she had curves that would turn heads one day. She had just wished that it wouldn't be as she walked up a set of stairs the day after she'd shrunk the regulation plaid skirt in the wash. Eyes fixed firmly to the floor and her mahogany cheeks burning almost as bright as her cherry red hair she didn't notice who was sitting right at the edge of the aisle as she approached.

That was until her hand connected sharply with Helena's ass.

The sound of the impact silenced the usual end of lecture chatter in perfect timing for the squeal of surprise that left Helena's mouth. Face burning brighter, Helena ran as fast as she could up the rest of the stairs to the door, trying in vain to ignore the wolf whistles and cat calling. Slamming the door shut behind her Helena pulled out her inhaler and breathed deeply, planning her next move. If she was quick she could make it back to her dorm room before rumours of that embarrassing noise she made in the lecture hall spread. Not to mention putting some ice on the stinging handprint she had no doubt was forming. Trying to pull her skirt down further she muttered a curse at the Dean for not allowing women to wear tights in the summer before stepping out into the corridor. It was tastefully decorated and filled with students leaving their classes. In the depth of the crowds someone caught her eye. The man was a complete stranger to her but Helena recognised that green sheen rippling over his eyes and her blood ran cold. He lumbered towards her with arms outstretched and a grin that was not his own on his lips. Without thinking, Helena turned and moved in the opposite direction as fast as she could. She shouldered her way through the crowd, hoping her pursuer wasn't gaining on her.

Students were forbidden to use their abilities on each other or staff outside of the classroom. Unfortunately for Helena the bane of her life possessed a form of mind control, all she needed to do was to lock eyes with her victim and they were hers. From what Helena had learned she could only control one person at a time but they were hers until she decided otherwise. Moreover, she had no care for the risk of being caught.

At that moment Helena felt a firm hand grabbing her arm, she spun around to see the man right in her face. Panicked, she grabbed her inhaler and held up to his face. Her own abilities allowed her to control technology she was touching. She reached out to the little computer in her self-replenishing inhaler and told it to dump the lot. A cloud of white mist jetted out into the face of her attacker, blinded and coughing he staggered away from her. Head down and with a hand holding her glasses in place Helena forced her way through the crowd as best she could. Every now and then she would catch a glint of green out of the corner of her eye, she ducked down corridors or through doors in a desperate attempt to avoid it. Eventually the crowds thinned to the point no one was in sight. With a sigh of relief Helena moved to take a dose of her inhaler before realising it would need to recharge still.

It was then that her blood ran cold as she realised where she was.

The "techno suppression" room, part of the gym complex and designed to stop people with abilities like hers from cheating in physical exams. She was standing right outside of it. She hadn't luckily escaped at all, she'd been herded here.

"Hello there Helena," came a sinister yet almost musical voice from behind her, "where'd you go? I wanted to talk to you after class..."

Helena's breathing came in panicked pants as her heart felt as though it was going to beat its way out of her chest. Still she kept her eyes locked on the door in front of her, it was her only hope, make eye contact once and she could do what she wanted with Helena. Heeled footsteps moved closer, each clack of them on the hard floor made Helena jolt. She had to think of a way out of this and quickly. In her pocket she felt her inhaler buzz, the sign that it was ready to be used again and a desperate plan formed in her mind. Taking a deep breath to steady herself Helena clutched her one weapon tight and readied herself to spin around.

It was then though that she caught a glimpse of what would seal her fate. Reflected in her own glasses were the emerald eyes of Tesha, her tormentor. A cold chill passed over her body but as she tried to struggle all Helena found was that her muscles would not obey her, no signal would reach them.

You know what I want, through the door you go little plaything.

At the instruction of Tesha's voice in her head Helena's limbs moved on their own and carried her through the door ahead of her. In an instant she felt any and all connection to the electronic signals that brought her so much comfort severed. She was alone and helpless.

Turn, face me.

Once again her body moved, despite her mind's screaming protests, and she took in the sight of Tesha. The other woman could have been her opposite. Easily standing head and shoulders above Helena with an athletic figure. Everything about her screamed that she was the one in charge, screw the rules. Her regulation blouse was tied open, exposing full breasts and a pierced belly button. The sleeves of Tesha's blazer were rolled up to expose arms decorated with tattoos of intertwined roses on olive skin. Her hair, the colour of burnished orange, fell in loose rings down to the middle of her back. She exuded confidence and sex appeal, unlike the meek and mild Helena. The smile that parted her ruby red lips oozed with ill-intent.

"Helena, you should know better than to run from me when all I want to do is spend some time with your reject ass. After all, no one else does, do they?" Tesha laughed wickedly, "besides I thought your ass looked cute in your uniform for once and I wanted a better look."

Helena staggered back a step as Tesha's control was suddenly released. Confusion filled her, alongside the urge to flee, but she dared not move. Fighting back tended to only make things worse. Tesha tilted her head to look at her.

"Hmm, it seems you're learning your place in life, staying still without needing my control. What a good pet!" Tesha mocked.

Helena felt her cheeks burn bright at the humiliation but she stayed put, simply wishing for this all to be over.

"Now let's have a closer look at your outfit shall we?" Tesha purred as she stepped in close, right up to Helena's face.

Helena flinched, expecting a slap to land but the only thing was forthcoming was a mocking laugh at her reaction. Tesha took a moment to eye her up and down, all the while Helena cringed and tried to pull away without moving a step. The taller woman's breath was hot on her cheek and sent an odd thrill through Helena's body. Then, without warning, Tesha moved like a striking cobra taking a hold of Helena's blouse with both hands and pulling outwards. With the sound of ripping fabric the flimsy material came apart exposing the large globes of Helena's breasts and her soft stomach. Helena cried out in shock and took a step back only for Tesha's hand to dart out. It clamped around her wrist with a vice-like grip and with a sharp wrench Helena's arm was pinned behind her back and her ear filled with Tesha's mocking laughter.

"Did you think because you're not under my thrall right now you could take me? You stupid bitch!"

With her free hand Tesha reached around the front of Helena and yanked her bra down before taking a handful of one of her breasts. She squeezed harshly, making Helena cry out in pain as she squirmed in Tesha's grip, begging her to stop.

"How many times little bitch? Not until I'm done with my inspection of you," Tesha's hand ceased it's assault on her breasts and moved down along Helena's stomach, it's goal only to clear, "and I still have one last place to check..."

Panic filled Helena, her lungs felt as though they were about to seize, her heart trying to pound its way free of her chest. Tesha's hand felt almost ticklish as it insidiously began to slip under the waist band of her skirt. Desperate, Helena made one last attempt to be free, lifting her foot and slamming it down. It connected with its target and although she was wearing the mandated soft pumps, Helena's strike drew a cry of pain from Tesha. Helena seized the chance and staggered forwards free of her attacker's loosened grip.

"YOU FUCKING UNGRATEFUL WHORE!" Tesha screamed.

In the blink of an eye she crossed the gap between the two of them and easily knocked Helena's defensively raised hands aside. Tesha's hand wrapped itself around Helena's throat and lifted her up with unseen strength. Helena's eyes went wide as her breathing was cut short, her hands struck at Tesha's arm but to no avail. The woman's grip was like steel. Just as her panic reached its crescendo it came, that telltale flash of green in Tesha's eyes and Helena's body went limp. Only able to hang there as Tesha squeezed harder, a cruel snarl twisting her lips. Just as Helena thought she could take no more, Tesha struck her hard and fast in the stomach before releasing her grip. Helena hit the floor hard, wheezing, winded and completely unable to move. She could only stare in mute horror as Tesha pushed her onto her back with her foot.

"That was really mean of you..." Tesha whined with a mocking pout, "so now you're going to make it up to me, understand?"

As she spoke Tesha moved so that a heeled foot was either side of the sprawled out Helena's head. Unable to close her eyes or turn her head away, Helena was treated to a clear view of what was under Tesha's skirt. Her perfectly smooth pussy most certainly wasn't hidden by any underwear and glistened with arousal. Helena tried in vain to move as she realised just what was coming next but she was unable to even twitch her fingers. She could only watch as slowly, inexorably, Tesha lowered herself down onto her knees. Her wet sex grew closer until it was centimeters from her nose, Tesha's skirt covering Helena's head and reducing her world to just the heat of her bully.

Show me how sorry you are bitch. Please me with your mouth.

A soft whimper escaped Helena's lips as her mouth opened wide and her tongue reached for Tesha's pussy. When they finally touched, Tesha's excitement at her assault of Helena was only too clear as sweet, salt coated her tongue. Then Helena's tongue moved of its own accord. This wasn't their first time doing this and Tesha had, much to Helena's humiliation, trained her on how to pleasure her using her power of control. Long, slow strokes with the flat of her tongue first, forcing her to savour the warm, wetness of Tesha's pussy. Helena felt Tesha's thighs tense each time her tongue rode higher to brush over the woman's clit. This slow pace was not to last though as the rest of her unwilling training began to take hold. The tip of her tongue swirled in circles around that little bud of pleasure, making Tesha moan with delight from above her. It filled Helena with guilt that her body felt a little thrill of excitement at the sound. At night she would lay awake trying desperately to figure out if she had actually come to enjoy it or if Tesha had conditioned that response.

She wasn't such a degenerate as to be liking this suffering surely?

"Mmm... Pet you are definitely very sorry at how you acted towards me aren't you? Keep this up and I might let you walk back with your clothes on..." Tesha spoke between ever louder moans.

Fear filled Helena's mind then, she knew Tesha was not bluffing. That she would force her to walk back naked. She tried desperately to put more effort into what she was doing but her body remained on the twisted autopilot that Tesha had locked her in. Even now her tongue slowed down once more, to tease Tesha just how she liked before the big finale. Slow flicks with her tongue, just barely touching, until Tesha commanded otherwise. It was working too, Tesha had begun to grind her hips on Helena's face, smearing her lips and chin in the other woman's nectar. As Tesha's movements grew quicker and more urgent, so did Helena's, until Tesha's thighs were shaking with the orgasm that welled up inside of her.

Finish me!

The command hit Helena like a brick. Her entire mind and body bent towards this one task. Lack of breathing thrust aside she buried her face in the pussy before her. Licking, kissing, nibbling with gusto she hoped was borne of another's control. As if on cue, Tesha's body responded. Her back arched and her hands reached down to grip Helena's hair, holding her head in place. Helena needed so desperately to breathe but she knew it wouldn't happen until Tesha was content. The other woman was trembling now as her moans of pure bliss filled the room. It seemed to go on for eternity until Tesha's hands released Helena's hair and let her head fall to the floor. She watched on as Tesha stood on shaky legs, her inner thighs smeared with Helena's drool and her own arousal.

"I think that apology was acceptable," Tesha groaned as she straightened out her appearance once more, "Helena I know you're the class reject but you look a fucking mess laid down there, I would be cruel to not sort you out wouldn't I?"

Stand up.

Helena obeyed mindlessly, her arms hanging limp by her side and her head up straight.

"Your uniform and your face is a mess."

So strip.

Helena felt her eyes widen in panic as she did as she was bid. Her blazer fell to the floor, followed shortly by her ruined blouse and her bra. Part of her felt relief at her breasts being bared in the warm open air but the feeling was quashed by what was next. Her pumps and socks were added to the pile next but as she reached for her skirt another order came from Tesha.

You really don't have any sex appeal at all do you? Turn around and bend over, take them off and give me a show!

Another pathetic whimper left Helena's lips as she turned around and bent forwards, exposing her ample ass to Tesha. Her thumbs hooked the waist-band of her skirt and pulled downwards, she could feel her cheeks flushing red as she revealed her ass inch by inch. Once her skirt had hit the ground she felt a sharp sting as Tesha landed an appreciative slap on her bare rear. Helena didn't pause though, she couldn't after all. Swiftly her hands were repeating the process with her panties and then there she stood, bent over, naked and exposed. She could feel tears welling in her eyes as Tesha moved around her, inspecting her, groping her, mocking her.

"Hmm you are a fine piece of ass pet but you just don't know how to show it off! Not to worry, I'll help you!" Tesha laughed sarcastically, "I'll take your clothes for you so you have to get some new better ones! Either get a tighter top and smaller skirt or I'll be taking them again, understood?"

Nod yes.

Helena nodded in coerced agreement with Tesha's faux deal. Her bully picked up her clothes and tucked them under her arm before giving Helena's ass a squeeze and heading for the door. Before she pushed it open she paused and turned back to Helena.

"This room isn't booked for the rest of the day and there's ten minutes before everyone is let out of their lectures. More than enough time for you to get back, *if* you run," Tesha said with a mocking wink, "oh and one last thing..."

Bend over and spread your ass cheeks for me. Wait here for nine minutes before you can leave. Hope no one comes in...

A single tear trickled down Helena's face and landed on the floor...

"Why me..." she managed in a hoarse whisper. 

—

 60 seconds until the end of lectures...

Helena had counted the seconds as they passed until Tesha's deadline. By the time it arrived her face was stained with tears and tremors ran through her body for holding her position for so long. For a moment she stood swaying on her feet, mental and physical exhaustion overwhelming her. Then she remembered what Tesha had said and the math fell into place, she had just one minute to cross campus to her dorms before everyone was freed from their lectures and they spilled into the corridors.

A minute that was already ticking away.

Helena barrelled through the door into the corridor and ran over to one of the holographic maps that shimmered on the intersection wall. Placing her hand on its projector she patched herself into its computer, within seconds it had told her where she was and the quickest route back to her room. The time it had given her for the route was three minutes. Helena cursed under her breath, unfortunately it was her only hope to escape further humiliation. She set off at a sprint, picturing the path she needed to take in her head. The university consisted of several large circular platforms covered in domed heat shields, linked by long bridges, that almost filled the cauldron of the volcano they resided in. The layout of most of them was the same, classrooms, gyms, food halls, all the things that a university needed arranged in the center. Around the circumference was then a ring of a building containing all of the dorm rooms. In theory it meant that all classrooms were within five minutes of where the dome's residents slept.

For Helena it meant that everyone she lived alongside would see her naked and crying if she didn't make it.

45 seconds until the end of lectures...

Her path would take her first out of the gym complex with the techno-suppression room. For a moment Helena debated diving into the changing rooms and hiding in plain sight in the showers. There were two problems with that though. The first was that the gym showers were completely open plan. Everyone could see everyone in all their glory. For a while Helena had actually enjoyed this, most of the women at Vulcan University were beautiful. Watching the steamy water cascade over their tense post-workout bodies had been the only highlight of the mandatory workouts they had to do. 

Then Tesha had made a joke about Helena staring at the other girls in the shower.

Now they would all giggle or sneer at her and turn away. That hadn't been enough for Tesha of course. Her bully never did anything by half measures, it had taken a week for the mocking of Helena to die down to a level Tesha was bored with. Helena had taken to waiting until everyone had left to shower herself quickly before the next class. Tesha had of course noticed this. So whilst Helena was in the shower one day she'd returned and stepped into the showers herself. Completely naked she had been quite a sight, her toned body cutting through the steam like a hungry shark. Some dark and guilty part of Helena had actually hoped something was going to happen between them. The nudity had just been to get Helena to look though. Seconds later there had been that all too familiar flash of green. In the next moment Helena found herself on her ass, legs spread, masturbating under the hot water of the shower. Tesha's grin had leered out of the steam at her as she tossed Helena's clothes into the pooling water on the floor. Tesha hadn't let her leave until a minute before her next class that time. 

Making Helena panic was clearly a favourite pastime of hers.

30 seconds until the end of lectures...

Helena shook her head to clear the memories, she couldn't afford to get distracted just now. The next part of her plan would require focus. Already her breathing was becoming difficult and sweat had started to sheen on her dark skin. Up ahead though was the library, at this hour it would be almost empty and would give Helena a chance to speed things up. Vulcan University prided itself on being at the cutting edge of technology, so even though they had quaint physical copies of books they were tended to by a fleet of automated drones. The door to the library was just up ahead but Helena knew she was running out of time, she would have to risk not checking if anyone was on the other side of it. She slammed through it and stumbled out of one of the library's side entrances. She thanked her lucky stars for the shelves around her that hid her naked body from view. Taking a deep breath she picked up a book and dropped it on the floor with a thud that broke the silence of the large room.

Instantly she heard it approaching, the whir of the drone's motor. Her body tensed involuntarily. Another unpleasant memory brought forth with it. Helena had enjoyed the library when she first arrived. No one would come here as the information the books held could be accessed online even easier. The long rows of shelves held a safety that Helena had relied so heavily upon, she'd even found herself a desk in a hidden corner and it became her sanctuary. Of course she should have known that no sanctuary was safe from Tesha. She didn't even know why her bully had been in there or how she'd found her. One minute she was enjoying her book on developing hacking skills and the next a perfectly manicured hand had grabbed her under the chin. Her head had been yanked back and she'd locked eyes with Tesha. Her bully had then made her sit on the desk, take off her underwear and spread her legs whilst Tesha took her chair. Over the next ten minutes Helena had been made to "entertain" Tesha. Teasing her own body against her will, working her arousal higher no matter how hard she willed it not to. Helena had been made to start with her breasts. Pulling them free, kneading them, pinching the nipples, pulling on them. All until she was panting with unwanted excitement that battled with the panic that someone would find her. 

Tesha had then made her run her fingers along her inner thighs, right the way until they rested on her pussy lips. It had shamed Helena most that if she could, at that moment she would have begged Tesha to make her play with herself. She hadn't needed to though as she'd been made to slide two fingers inside of herself. Finger fucking herself whilst Tesha watched, able to see everything of Helena from where she sat. The other woman had her hand up her skirt, apparently enjoying the show greatly. It had only ended because of the sound of one of the drones coming around the corner, Tesha had jolted up in surprise and accidentally released Helena. Helena had been left alone, panting and needy staring at the shiny white shell of one of the drones hovering before her. Hoping beyond all hope that they didn't record any security footage...

15 seconds until the end of lectures...

"Fuck..." Helena swore under her breath as the drone came down the aisle towards her.

Her usual air-headed nature was proving to be a curse today. Worst of all, that memory with Tesha in the library had stirred something within her, she could feel that familiar heat building in her core. Although it had been humiliating, the orgasm Helena had after she'd made it back to her room after had been the most intense in her life. Exasperated and panicked, Helena tried to push the memory out of her mind.

++ MISTREATMENT OF BOOKS DETECTED. REPORT TO LIBRARIAN AUTOGENERATING++

The drone’s metallic voice grated in the quiet of the room. The drone itself was a sphere of plain white fibre glass about the size of a beach ball that floated using its own anti-grav. Helena dived towards it before it could register what she was doing. As soon as her fingers brushed the drone’s surface she delved deep into its command core code. Her eyes flickered behind closed lids as she made rushed adjustments to what she found there. In seconds her task was complete and the drone lowered itself until it floated just above the floor. Keeping her hand in place Helena sat atop it like a horse with her legs clinging to its smooth surface.

With a groan she immediately regretted her nudity.

The soft vibration of the drone between her legs would have, in any other situation, been something she would have craved to feel. It's soft thrum only made that glowing warmth in her core burn brighter. Helena bit her lip and tried to shut it out, but as she commanded the drone to rise the vibrations grew more intense and a soft gasp escaped her lips. How embarrassing it would be to be caught like this as well as naked. With one hand clamped tight over her mouth she commanded the drone to head for the nearest side exit. The door to the outside opened automatically as it approached and along with it came the riskiest part of her plan.

Between the library and the outer ring of dorms was "The Green" as the Vulcan staff had dubbed it. A field that had been planted with the thought of giving the students a space to sit and read in the outdoors. In reality it provided a space for them to fuck and drink outdoors in the cover of night. Helena took one last gulping breath to steel herself and almost jumped out of her skin as the bell that marked the end of lectures rang across the dome. A few precious moments were lost as she recovered the wits to act. When she had, Helena made the drone shoot off the mark as fast as it could with its extra load. The drone was sent careening over the neatly cut grass at a break-neck speed. Helena's legs shook at the delight the vibrations of the smooth shell between her legs brought to her. She jammed her hand into her mouth, her teeth biting into the pad of her thumb to stifle the moan that threatened to escape her lips. Helena could see through the windows that looked out onto the Green the students that were filing out of class and would soon be joining her outside. She could only hope she was going fast enough that no one would recognise her. The building with her dorm was fast approaching but keeping her focus to steer the drone safely was only growing more and more difficult with the distraction it provided. Her body was aching with the effort of staying on board whilst trying her hardest not to cum on her flight to safety.

Although the few seconds to cross the open space felt like forever to Helena, the drone made it to the building just as she spotted people stepping out of lecture buildings to head to their own dorms. Thinking quickly Helena directed the drone to fly up to her window and hastily she threw it open, thanking her lucky stars again that she'd left it unlocked. She had to almost lay flat to fit through the open window on the drone but the two of them made it into safety, wherein Helena flew it down to land on the bed. 

As she would later deem to have been against her better judgement, Helena did not dismiss the drone immediately. 

The burning desire in her core, born of guilty pleasure or not, demanded attention. Helana straddled the drone on the bed as she ground her pussy against its smooth surface. Her body trembled as she activated the anti-grav, pressing it up against her and intensifying those wonderful vibrations. By this point her pussy was slick with arousal and moved over the surface with ease. Each rhythmic back and forth of her hips drove her arousal higher until her back was arched and her legs shook uncontrollably. Part of her mind was screaming at her about her window being open as she moaned but the rest of her didn't care. She'd had a shitty day and Helena was going to enjoy this moment whilst the adrenaline of her flight across campus still buzzed in her veins.

"Fucccckkkkkk..." she groaned as she ramped up the vibrations as high as they would go.

Helena's eyes rolled back in her head as the tsunami of pleasure washed over her, her mouth hung open in a silent scream of bliss as her body shook over and over. Soon she was unable to balance herself any longer and she fell forwards, both of her hands gripping the bed for dear life as the aftershocks of her orgasm passed. Slowly she slid forwards off of her impromptu toy to lie face first on the bed. 

As soon as she lost contact with the drone however, its grating mechanical voice issued forth once more.

++TAMPERING DETECTED. FORCING REBOOT++

Helena's eyes had begun to close dreamily but now they shot open wide. She dived for the drone but before she could touch it, it lifted up out of her reach.

++LOCATION: FIRST YEAR DORMITORY. REASON: UNKNOWN. RETURNING TO CHARGING DOCK++

"Shit..." Helena muttered as she watched the kidnapped drone fly out of her window back the way it had come.

She fell back onto her bed and groaned. Between Tesha and her own uselessness her first year at Vulcan University was not going as she had hoped. Her absence from the lecture she was now supposed to be attending would no doubt be noticed and recorded. Another on a long list of absences and flunked tests; most were the fault of Tesha but she had to admit that many were on Helena's head alone. She found many of the classes boring, she already knew most of the material and so barely put any effort in. With a grunt of effort Helena pushed herself off of her bed to pad over to her desk on shaky legs. She dropped into her chair and turned her laptop on with a tap of her finger on the screen. No need to waste time entering your password when you're a technopath after all.

"Shit..." she muttered again.

Her email inbox had received several new additions in the last hour. The first two were about her absence in the last lecture. The first was an auto generated one to inform her that her absence had been recorded. The second was from her head of year himself. Given it was her third infraction this week she was going to face disciplinary action for this, the manner of which was to be determined this afternoon. She was to meet Vice-Dean Apollon at the gym early before the afternoon's exam. Helena threw her head back and cried out in exasperation, she'd forgotten all about the exam. The physical tests were by far her worst subject, no matter the effort she put in she was quite simply just bad at them. There were a few emails about late coursework but it was the final one that made her heart plummet in her chest. It was from the librarian, banning her from entering the library for a month for the mistreatment of a book.

Helena slumped further down in her chair, the day was already a terrible one and it was barely even lunchtime. She decided to make the most of being back in her room earlier than anticipated and use the time to work on her personal project. Helena slipped her bath rope on and placed her hands flat on her laptop's keyboard before closing her eyes. To anyone watching it would appear as though she was meditating as her laptop opened and closed windows, lines of code seemingly writing and running themselves. Only Helena knew what she was truly doing.

Soon she would be defenceless no more, Tesha would have a taste of her own medicine...

Afternoon Exam

The sun shone bright through the arched glass roof of the bridge as Helena rode the travelator along it. The heat shield flickered softly in ripples of purple just inches above the glass. Without it everyone on campus would fry in moments, instead they all remained balmy and warm all year around. A fact that suited Helena well as she made her way to the exam dressed in the university's "physical activity" uniform. A tight fitting white t-shirt and small booty shorts. The latter of which did very little to actually contain Helena's ass and were form fitting to the degree she dare not wear panties underneath them The top was a similar story, she was one cold breeze away from everyone being able to see that she had no bra on underneath.

Although each year’s dome had its own gymnasium for exercise, Vulcan university also had the "Training Dome". There were no dorms in this one and instead it contained an array of high-tech facilities for the practice and development of the students' various abilities. Each quadrant of it was themed for something else with tiers of seats running around the edge of the whole dome. It was at the top of the ring of seats that Helena met Vice-Dean Apollon. He was waiting for her in the observation room for the assault course quadrant, watching the various camera feeds as the mechanised arena set itself up. He looked up at her as she entered and waved her over to the chair next to him.

"Helena thanks for coming to see me right before your exam," he began after a pause to finish his task, "unfortunately it's to be another of those chats again. I saw you missed another lecture this morning, why was that?"

Helena felt her cheeks blush pink at the thought of what she had been doing, bent over, pussy exposed in a room anyone could have walked into. She turned her face from the Vice-Dean to hide her reddening cheeks.

"I..." Helena stammered, "I wasn't feeling well so I went back to my dorm."

Apollon shook his head.

"You say that every single time and yet I find myself not believing you. Not only are you fine now but I received a notification that you were causing trouble in the library."

Helena felt her blood run cold at that, she opened her mouth to speak but Apollon raised a finger to silence her.

"I've paid it no heed, that old bastard is mad on power in his own little kingdom. I cannot ignore the fact though that you have clearly been dishonest," he let out a tired sigh, "I don't know what's going on with you Helena but I know you're a bright pupil, you could even be our best. I believe in you and because of that I'm going to give you a chance."

He stood and walked over to the window overlooking the assault course.

"If you pass this exam, and I say pass not ace it, I will wipe your slate clean of absences for this term. A fresh start. If not, well then I must be wrong about you and I'll look into having you dismissed from Vulcan. Is that fair?"

Helena's head was spinning. She felt as though she was going to fall off of the chair in shock. This was do or die, she could wipe away most of the trouble Tesha had caused her or she could crash and burn. She swallowed hard before nodding.

"Yes... That's... I'd like to do that," she replied meekly.

A bright grin split Apollon's face and he clapped his hands together.

"That's wonderful to hear! I knew you had a fighting spirit in you!"

For a moment he looked at his watch and tapped the screen on its face, Helena heard the door to the observation room swing open behind her.

"Because I believe everyone deserves second chances I chose who you'll be paired up with for this. I've chosen one of the stars of our Hero track in your year. Follow her lead and it'll be a dead certainty you'll pass!"

"Hello Helena..."

A chill of dread snaked its way up Helena's spine at the voice of Tesha from behind her. 

—

Five minutes later Helena stood in the changing rooms with Tesha. Each quadrant had its own and much to Apollon's unknowing delight Tesha had suggested they go here to have a chat in private about how to make sure that Helena passed. Helena had kept her eyes glued to the floor, her body visibly shaking from nerves for the entire walk down. Her entire future was now in the hands of the woman who had decided to make it a misery.

"Well it seems then little pet you have to do whatever I tell you now," Tesha let out a malicious giggle.

“Tesha… Please…” Helena began to plead. 

“Oh shut it with that pathetic mewling,” Tesha scoffed, “we need to figure out how to give your plump ass any chance of passing this exam…”

Tesha tapped her finger to her lips with exaggerated theatrics. 

“What to do, what to do… How can we make sure you don't show me up by being your usual level of useless…”

Helena let her legs give out and drop her onto one of the room's benches, her head in her hands. She knew where this was going, Tesha had some new cruelty in mind for her. This was all just foreplay.

“Ah I know just the thing! I mean I was going to use it myself as a treat after the exam, but I do love giving to charity.”

 Helena unlocked a nearby locker and reached inside to remove something. 

 "Now you better be thankful I'm lending you this. It's a little booster, you're going to need it to pass."

Helena looked in abject horror at what Tesha held in her hand. It looked to be the head of a silicon vibrator complete with a little arm to sit against her clit. Embedded along that arm was a little screen.

"No... Please no. Not here, not today..."

Helena's pleading was cut off by a warning flash of green in Tesha's eyes, not control, just a reminder.

"Here's the deal, pet. I want to keep you around, you entertain me in my time at this dull place. So I will make sure you pass your test but only if you do as I say and wear this," she placed the device on the bench next to Helena, "I won't force you to wear it though, you have to choose to put yourself under my control today."

Helena stared from the device to Tesha and back again, her mind raced. There was no way out of this, the only way she would be allowed to do the test was with Tesha and the only way Tesha would let her pass was if she did as she was told. With a trembling hand Helena reached out and picked up the device, trying to ignore the thrill growing within her at what the ‘booster’ could do. 

"You can guess where it goes," Tesha said with a teasing wink.

Helena looked around for a moment trying to find somewhere to slide it in privately. Tesha shook her head.

"Bend over here in front of me to put it in. I can't have you trying to escape using it now can I? Remember if you don't do as I say..."

Shaking like a leaf in the wind Helena moved towards the bench, slowly she leaned forwards. Placing one hand on the bench she used the other to slowly inch her shorts down. Tight as they were, it was no easy feat. One Tesha expedited by moving up behind Helena and pulling them down with a sharp tug so that they fell around her ankles. Helena's gasp of shock sounded like a thunderclap in the empty room. She bit her lip as Tesha ran her hands along the back of Helena’s thighs, dragging her nails lightly along the sensitive skin. 

“How else would I get through a day of classes without my favourite curvy stress toy…” Tesha purred, a throaty, sultry edge to her words.

Helena felt her body tense as her bully's hands moved higher and higher, until two perfectly manicured fingers were running over the already tingling lips of her pussy. Helena could not help but whimper as Tesha used them to expose Helena's most private region completely. Helena squirmed, but did not pull away. Whether out of fear or some twisted desire to obey she did not know.

"Fuck little pet are you really such a dirty bitch that you're enjoying this?" Tesha mocked, the edge to her voice sending a shiver up Helena's spine.

Helena opened her mouth to give some feeble objection but the feel of Tesha's tongue running over wet pussy sent her eyes rolling back into her head and the words along with them. The drone had left her sensitive beyond anything she had ever experienced before. Tesha's ministrations sent every nerve ending firing like blazing stars.

"Well this is perfect," Tesha paused for a moment to spit on Helena's exposed hole, "put the booster in my obedient pet."

Helena whimpered at the feel of Tesha's hot spit as it dribbled down her pussy and onto her thighs. She took a deep breath and obliged, what other choice did she have after all? She slipped the booster into her hand and raised it between her legs. Thanks to Tesha's ‘aid’ the head of the booster slipped into her with ease. Helena let out a low moan as she pushed it in as far as it would go. The device was warm and just a little bigger than she was used to, the smaller arm rested snugly against her clit, making her want to squirm against it already. Panting she moved to stand up but Tesha's hand on her neck pinned her in place.

"Now to activate it."

As soon as Helena felt Tesha tap on the device's little screen she felt a change. Helena gasped, her hands scrabbled on the bench for purchase to push herself up but Tesha’s grip was too strong. The device's arm inside of her had inflated, not enough to be uncomfortable but enough that she wasn't going to be able to remove it herself. It was stuck in her until Tesha took it out.

"Now let's test it shall we pet? Put your hand on the light switch and turn it off and on."

Tesha's grip released from the back of Helena's head and Helena shot upwards then away on shaking legs. Eagerly Helena pulled her shorts back up, suppressing the moan that bloomed within her as they moved the device slightly. Meekly she moved over to the switch with her head bowed.

"What does it do? How will this help me in the exam..." she mummered. 

Despite the situation her mind could not help but feel intrigued, but a glare from Tesha brought her back to her task. With great trepidation Helena placed her hand on the switch and sent out the command to dim the lights. 

Two things happened at once. 

The lights turned off and a low buzzing vibration pulsed within Helena's body. Helena gave out a gasp of surprise as her legs buckled slightly underneath her. Tesha's mocking laughter filled her ears.

"This is a sex toy! It won't help boost my abilities at all!" Helena cried out in anguish, her hopes of passing seemingly dashed.

"I never said it boosted your abilities did I? You really thought I'd slip you something like that? No you fucking dumbass it's an arousal booster, set to trigger whenever the wearer uses their abilities. You need it to pass because unless I'm having fun I'm not going to help you. Now turn the lights back on," Tesha demanded.

Helena braced herself for the pulse of pleasure but even still it caught her off guard as she used her ability again. The pulse was stronger this time and sent jagged sparks of pure bliss arcing through her. She let out a groan of exasperation and buried her head in her hands.

This exam was only getting worse and worse. 

— 

Gingerly Helena walked out onto the testing arena. She shuffled along behind Tesha walking with her shoulders hunched and an odd gait, trying in vain to prevent any more pressure on the device within her. Many of the other students in their year had already completed their exam, now it was their turn. Though in Helena's opinion they had not been quick enough. Sitting in the waiting area with the ‘booster’ inside of her had been agonising arousal. Even without it activated she could feel it filling her, any movement making it rub against her. Several people had asked her if she was unwell given her tense expression and bright pink cheeks. 

She hadn't even been able to string together words in response. 

Slowly Helena looked up and tried to suppress the growing dread within her. Before them lay the start of the assault course. A large metal door set in a wall built from individual metal cubes, each the height of Helena. Her heart was pumping hard in her chest and her head was spinning as the anxiety of needing to pass filled her. There was no way to prepare for the course, the entire thing was adjusted to suit the pair that was to run it and the only way to pass was to reach the course's end. If you tapped out or fell off then you failed and in Helena's case were doomed to leave Vulcan University.

"Do exactly as I say pet, I do not care if you fucking want to or not. Understood?"

Helena looked up for a moment and immediately shrank back at the fierce glare in Tesha's eyes. She had tied her orange hair up in a pony tail and gone was the mocking snarl. Instead her jaw was confidently set, ready for anything. Helena let out a frightened squeak and nodded. Second by agonising second the counter above them ticked down to zero and the metal doors began to slide open. Tesha was off the mark in a flash, sprinting for the gap. In moments they were in the first section of the course. The metal cubes of the walls had been arranged to create a bridge that spanned a large pool of water. The bridge was thin, only wide enough for two people to cross side by side. Blocking their path upon their only path forwards stood two of the university's training staff with shock batons and tinted visors. The goal was clear, get past them. Tesha grinned.

"This one's for me, you hang back."

Tesha charged forwards, leaving Helena to stand and watch. The woman’s toned body was not just for show and made it known with perfect clarity. Switching from a full sprint to a slide in the blink of an eye as she slid between the first guard’s legs. She was up again in an instant, her legs whirling through the air to strike him in the back and send him toppling into the water. The second swung their baton straight for her head yet Tesha didn't move. Instead Helena saw that familiar flash of green as she locked eyes with the guard. The baton didn't stop coming however and Tesha threw herself backwards to narrowly avoid being hit by it. She staggered back to the edge of the bridge off balance as the guard advanced. Helena felt her heart catch in her throat, there was no way she could win this without Tesha.

"Fuck. Fuck. Fuck," she cursed under her breath as she ran towards her bully in peril.

Everything felt as though it had begun to move in slow motion. The guard thrusting forwards with the baton to knock Tesha off the bridge barely even registered Helena coming towards them. They likely didn't expect her to be strong enough to stop them and they'd have been right. Instead though Helena grabbed the baton itself and practically screamed a new command for it through her ability. The sensation was like nothing she had ever felt before. The pain of the baton's electric field lanced up her arms only to meet an intense pulse of pleasure from the booster. Helena's eyes flew wide and her legs gave way beneath her as her brain overloaded from sheer overstimulation.

Her plan had worked though. The electric field shifted its focus to the handle of the baton, sending it through the body of the guard. Every muscle in their body spasmed as they were launched off of the bridge into the water below.

"Get the fuck up pet you're embarrassing me," Tesha demanded gruffly as she grabbed the collar of Helena's top and hauled her to her feet.

Helena swayed where she was for a moment, her eyes glassy as her brain tried to process what had happened. All the while Tesha looked everywhere but Helena, just the slightest hint of pink colouring her cheeks. Finally with a grunt of frustration Tesha dragged Helena across the rest of the bridge and into the next room.

"Fuck..." the taller woman swore as they entered.

As per the exam regulations there was a room to test each of them. Tesha had hers and now it was the already woozy Helena's turn. The room was vast and yet had very little floor. Other than a strip of cubes under the start and exit doors the rest was a watery path to failure. The only other visible feature was an anti-grav platform hovering right in front of them. Barely big enough for both of them it also lacked any form of visible control panel. Tesha propped Helena against the door frame and slapped her hard across the face. Helena let out a soft moan but slowly her eyes began to gain focus once more.

"What... Where are we?" she asked.

"Wake up, you've got to ferry our asses across and don't you dare fuck it up you hear me?" Tesha snapped at a wide eyed Helena.

Helena took a deep breath and nodded. Even with her head spinning, technology was her thing. She swallowed nervously, the booster though might pose her a problem. The two of them stepped onto the platform and she knelt down to place a hand on it. Helena stifled a moan at the pleasure that started as soon as the ability reached out to the machine. Helena bit her lip to keep herself quiet, hanging her head low to hide the growing flush on her face. If she was going to get them across the gap she was going to have to use her abilities constantly. Whether it was her own arousal making her more sensitive or the vibrations growing in intensity Helena could not tell but the pleasure within her was growing with each passing second.

"Aw what's a matter, pet, can't even get us across the water? Are you really that pathetic?" Tesha sneered before adding in a lower, more sinister tone, "remember the Vice-Dean is watching so you better stay quiet..."

Helena whimpered, in the haze of her scattered brain she'd forgotten the extra complication of not being caught. Helena took a deep breath and sent the command to the platform for it to begin moving. She bit her lip to stop any noises escaping her mouth as each new command she sent to correct the course made the booster pulse higher and higher. They were barely even half way across and already she could feel her concentration slipping. Helena could feel how much of a dripping mess she was between her thighs right now. Every inch of her skin felt alight with pleasure and worst of all she could feel her orgasm looming inexorably closer.

"I wondered when this would get more interesting."

Helena looked up at Tesha's exclamation and felt a cold sweat break out over herself. Three drones had risen up out of the water and were aiming what looked like miniature cannons at them. They would only fire bean bags but it was more than enough to knock them clear off of the platform given its small size. Once they had raised high enough to be level with the two women, all three fired at once.

Helena cursed through gritted teeth and commanded the platform to move faster. 

The projectiles tore through the space the two of them occupied mere heartbeats before. 

"Watch it you dumb bitch! I almost fell off!"

Helena couldn't respond. Her eyes rolled back in her head briefly as stars danced over her vision. Her lips parted as a moan escaped her lips. The price of the sudden burst of speed, courtesy of the booster. 

Tesha's hand connected with the back of Helena's head, snapping her back into focus with one final soft moan. There was no chance they would complete the test with the drones hounding them. They either had to outrun them or out fight them. And since Tesha couldn't attack at a distance…

Helena breathed in deep and clamped a hand over her mouth, her asthmatic lungs screaming in protest. She delved deep into the floating platforms computer, overriding every safety feature and setting the speed to its maximum. Their transport rocketed forwards, almost causing Tesha to tumble into the drink if not for her hand grabbing Helena's hair. Helena however, noticed none of this, the booster screamed within her. It blotted out every other signal in her mind but sheer unadulterated bliss. Her hand kept clamped tight by the tension in her overstimulated muscles was the only thing keeping her predicament secret. 

The drone’s projectiles sailed by behind them, unable to even come close.

And then the other side of the arena came to meet them. 

“SLOW DOW-”

Tesha's screamed warning was cut short as the platform collided with the ground on the other side of the arena and both women were sent hurtling through the gate at the far end. With a metallic thunk the gate closed behind them, sealing away the drones. Helena laid there on the ground twitching and mummering. Her overstimulated pussy had soaked through  her too tight shorts. She knew not if she had orgasmed on their impromptu flight or not.

Her broken brain also did not care.

Slowly some semblance of consciousness returned to Helena and she turned her head to Tesha sat next to her.

"We made it?"

Tesha nodded, momentarily lost for words, her usually pristine appearance more than a little windswept. 

—

Mercifully Tesha dragged her back to the changing rooms rather than going to get their official grade from Vice-Dean Apollon. Usually Helena would be eager to know but right now all she wanted was some release from the blissful torture that plagued her. Every motion was wonderful agony as her sensitive pussy brushed against her tight shorts. Each step brought forth quiet whimpers. For the first time in Tesha's presence she was all too eager to take her shorts off and expose herself to her tormentor.

She just wanted the booster out of her. 

Without even thinking she bent over the bench in front of Tesha and practically ripped her shorts off. Though, much to Helena's surprise, even with her bent over and exposed in front of Tesha, her bully did nothing.

Moment after agonising moment passed until Helena raised her head to look back at Tesha.

"Please can we just be done with this... Turn it off, take it out. Please!" she begged.

Tesha's evil smirk made Helena's legs turn to jelly.

"Oh you stupd bitch, it's not that simple. It will only turn off and let you go when it's finished. It doesn't matter how often you plead, fight it or cum. You're stuck," she leaned forward, her breath hot on Helena's sensitive skin, and tapped the display on the booster, "and by this little screen here you're only half way through."

Helena felt a wave of dread fill her. There was no way that it could say she was only half way to orgasming!

"No, no, no please no there has to be another way!"

"Don't worry pet, I brought something along to help. I'm not that cruel."

For the briefest of moments Helena's heart leapt but that hope fizzled out when she saw Tesha securing a strap-on in place on her now naked body.

"This thing is an absolute beauty. Full of all sorts of little gadgets, lube dispenser, pneumatic thrusting, growth, it can even vibrate. Sad thing is though I've lost its controller so you're going to have to make it work. Lucky for you that'll turn your other toy on," Tesha's smile only grew wider as she spoke.

Helena felt her whole body go taut, tears began to well up in her eyes. The elation of passing had gone now, all that was left was the guilt and dreadful knowledge that once again Tesha had outplayed her. She had no choice. As tears began to roll down her cheeks she nodded, making to turn around. A sharp slap on her ass from Tesha stopped that motion in its tracks.

"No, I'm not fucking your face, I've wanted to destroy your ass since I met you and you're going to let me as my reward for making sure you don't get kicked out."

Helena sagged as a sob escaped her lips. Tesha didn't wait for approval this time, instead placing the tip of it against Helena's virgin asshole.

"I'd start talking to it if I was you bitch, you're going to need the lube."

Her chest heaving with crying Helena reached out to the computer inside the strap-on. A sob was cut off midway through by a moan as the booster fired into life once more. Tesha had already begun pushing her hips forwards, in a panic Helena made the strap-on secrete far too much of the lube. The viscous liquid was cold and made her jolt as it splashed down the back of her legs. What was worse was the feeling of it against her asshole. Cold and unwelcome, Tesha pushed forwards nonetheless. Helena’s cry of pain echoed around the locker room as the tip of it breached her asshole. Her hands scrabbled at the bench as Tesha plunged deeper. The sensation was all at once agonising and erotic. Her constant contact with the booster meant no matter the humiliation of Tesha fucking her, Helena's body was still preparing to orgasm.

"There's a good little pet, take it all for me," Tesha purred, stroking the back of Helena's head as she did.

Helena choked back a sob as as the shaft filled her further, she felt as though she would split in two with both holes filled as she was. Desperately she commanded it to pump out more lube, her body tensing as a fresh wave of pleasure washed over her. Even with the humiliation of the excess lube dripping out of her and down her legs, Helena's mind was starting to become lost in the bliss. A desperate voice deep within her cried out for her to activate more of the toy Tesha was fucking her with. It was depraved and humiliating but at least it would finish her quicker. With one final push Tesha buried the strap-on to the hilt within Helena's ass. Helena shook, her sobs mixed with moans. Her face was as wet as her pussy but for very different reasons. Her mind was beginning to tear in two directions, surrender or suffer.

"There we go that wasn't so hard was it?" Tesha cooed as she trailed her nails along Helena's back, "now we can really begin."

"Please no more... Please I'll do anything just stop..." Helena pleaded.

"Anything? Be careful what you offer. For someone so smart you can be so very stupid. As you say you'll do anything though, make it grow for me. Let's really destroy your ass!"

Helena pleaded and mumbled over and over for mercy but did as she was bid regardless. She was too far lost in the depravity for anything else now. Her cry as it expanded inside her was a mixture of pain and pleasure which coalesced into a low groan as Tesha began to move her hips back and forth. It hurt to have her once virgin asshole stretched so harshly but something dark, deep within her was enjoying it. She could feel her toes curling with the glowing pleasure racing through her nervous system. 

Helena surfaced from her bliss addled mind for just long enough to feel her bully had pulled almost all the way out. The rational part of her realised what was about to happen and tried to force her mouth open to beg for mercy but it was buried too deep in the recesses of her brain now. All she could do was scream with delight unwanted as Tesha slammed her hips forward brutally. 

The force of it almost knocked Helena off of her feet. 

She crumpled forwards onto the bench, her arms now shaking too badly to support her. Tesha made sure not even this gave her release as her hands clamped tight on Helena's ample hips. The thrusts came quicker now that Tesha had a firm grip on her, pounding her ass whilst Helena grew louder and louder. The noises that left her mouth started off as sobs mixed with moans but changed slowly until she was practically screaming. Pain or pleasure Helena no longer knew. She was becoming lost to sensation. 

It would have been quite the sight for anyone who may have walked in. Helena's beautifully large breasts bouncing back and forth. Her legs slick with lube and her own arousal. The wicked grin of Tesha as she broke her chosen victim's will.

"Let's see just how badly you want to be free shall we? Trigger it again, make it grow as I fuck you."

Helena needed no encouragement. She acted purely on the reflex of the hopeless. Even though she was expecting it the effect was as though she had been electrocuted. Her back arched, her body standing high on tiptoes, mouth wide. Then the tremors wracked her as the first of what would be many orgasms ravaged her body. Tesha did not slow down, relentlessly she fucked Helena, encouraging her repeatedly to trigger some new feature. Each one accompanied with a jolt of bliss from the booster. Each one pushing Helena over the edge. The relentless teasing, the adrenaline, the sheer humiliation of it was all too much for Helena's mind. It shattered like a pane of glass until she was nothing but a limp fuckpuppet. Held aloft by Tesha. Her tongue hung drooling out of her mouth as she triggered her abilities spasmodically, sending herself further into oblivion.

Eventually Tesha stopped. With one last thrust she filled Helena, reached around the front of her to grab her by the throat and hauled her upright so she could whisper in her ear.

"Cum for me one last time and mark yourself as mine. "

Without even processing the thought Helena's body obeyed. The explosion that ripped through her body was beyond what she thought her ravaged nervous system could take. Her screams of pleasure filled the changing room as her legs gave out. This time Tesha did not support her with her hands, letting Helena impale herself on the strap-on as her legs sagged. With a harsh laugh Tesha pulled out of Helena's ass and let her fall to the floor where she lay twitching and whimpering. Lazily Tesha removed the strap-on and dropped it onto Helena's prone form.

"There, something to remember this by. Make sure you bring it with you next time."

It bounced off of Helena's prone form with no reaction from her. Helena just lay there, an occasional tremor running through her, her face caked with dried tears.

Tesha walked off without another word. A few moments later Helena heard the showers start up. Some dim part of her craved for one, to wash the mess away that she had become. She knew deep down though that nothing would wash her clean of this. Mere minutes or an eternity later, time mattered not to Helena right now, Tesha returned. Her lithe body was slick and steaming from the shower. She crouched down next to Helena's head, brazen in her naked confidence. With a finger under Helena's chin she tilted her head up to look Tesha in the eyes. Her’s bright and full of twisted excitement, Helena's lidded and drowsy.

"So I'll let you in on a secret pet. I lied."

Tesha grinned at the spark of anguish that bloomed in Helena's eyes as she watched.

"The little 'booster' has no such setting that it will only turn off after so much use at all," she leaned in close to whisper in Helena's ear, "not that it matters though, it's tech isn't it? You could have turned it off at any time but yet you didn't. Either you were too stressed to realise or maybe, just maybe, you actually want this."

She gently patted Helena on the cheek before rising to her feet and getting dressed. Tesha walked out without another word, leaving Helena a dripping, whimpering mess on the floor.

After School Activities 

A single pool of light is all that can be seen in the Vulcan University First Year projects laboratory. The space is open to anyone on the Support courses at all hours so that they can use it to work on tasks they have been assigned by their lecturers. It is not however expected to be in use in the dead of night, the glass walls of the large space usually looking out over the University now only showed the twinkling lights of the few students still awake in their dorms. The room's sole resident sat at her personal workbench, one of dozens lined in neat rows throughout the space. Helena's movements were slow as though she were exhausted, muscles aching but powering through it for some burning purpose. Every now and then she would swap between the array of complex looking equipment she was building and her laptop. Interfacing between them effortlessly.

Had a teacher walked into the room though they would have immediately recognised that she was not working on an assigned class project. The array of "gadgets" on the table were most certainly designed with a very specific use in mind. To her left lay what looked to be a modified version of the University guards shock baton. Altered as it was to more resemble a riding crop. Next to it was the strap-on "given" to her by Tesha, that Helena had added some of her own improvements too. Namely ensuring that only she could control it now, whether Tesha used the remote or not. Another was a butt plug, it looked innocent enough but the "jewel" was actually a screen that controlled how much of a potent aphrodisiac the plug would secrete. An excellent way to keep someone under her thrall. Finally there was her pride and joy. It had been a labour of love and the culmination of all that these gadgets aimed to do. To help her get her well-deserved revenge on Tesha. 

A mechanical bondage harness. 

Leather cuffs for the ankles, wrists and neck all connected by smooth metal "smart cables" of her own design. She had finished the code required to get them to work earlier today and it would allow her to manipulate the body of anyone she put it on. The motors and the unique properties of the cables meant that anyone who wore it could be moved around like a puppet by whoever controlled it.

Just as Tesha did to her.

Helena allowed herself a slight smile. Everything was coming together very nicely. All she had to do now was to run some tests and next time Tesha tried to make Helena her bitch she would be ready for her. Helena would turn the tables and have the satisfaction of seeing Tesha cry. She woul-

Her train of thought was cut off by the chime of the doors opening at the far end of the laboratory. Helena froze in fear. She had thought she was alone in here, desperately she cast around, looking for a place to quickly hide her personal "projects", explaining these to a teacher would be far more humiliation than she could handle after the lockers today. Then she heard the voices, torch beams played across the ceiling. Helena frowned, surely a teacher would be here alone and would just turn the lights on. Unless...

"It's a around here somewhere, they keep the alcohol for the first years experiments in one of these cupboards."

Helena dropped behind her desk as the voices grew closer. They sounded older, fourth years most likely. The whole year had a reputation for being unpleasant to those beneath them, doing practically whatever they wanted and with powers as well, they were a nightmare even for the staff. Now Helena was a witness to their breaking into the laboratory. There was no telling what they would do to her to ensure her silence. She put her hand over her mouth to try and muffle the sound of her breathing, then screwed her eyes shut and hoped that they wouldn't find her. There was nothing she could do to fight them if it came to it.

"Hey, what's that light doing on? Is someone here?"

Helena felt her heart drop into her stomach, how could she have forgotten? Her bench light was like a beacon in the dark to anyone in the lab. Her hand shaking with fear slowly Helena inched it higher to switch the light off. Just as she laid her finger on it though a hand clamped so tight around her wrist she thought her bones would break. She let out a scream as the figure lifted her up by it. The fourth year looked to be more beast than man, with bulging muscles and patches of fur, his accomplices stood behind him holding their torches. Helena caught a glimpse of fire playing over one of their fingers and sharp fanged teeth on the other.

"Just a first year," grunted one of the torch bearers, dismissive at the prospect of violence, "beat her senseless, let her know what will happen if she snitches on us."

The man-beast nodded and Helena's vision exploded into stars as he struck her across the face. She tried to cry out but how he was holding her she couldn't get any air into her lungs.

That's when she saw it. 

Just for a second a flash of green in the dark behind her attacker and one of the torch beams stopped moving. In the next moment it started again, quickly this time the bearer of the light was moving towards one of the glass walls. Then, with an almighty crash they ran through it, down into the darkness below. Her attacker dropped her like a broken toy as he cast about in confusion. There was another quick flash of green, a torch was dropped and he turned to face it.

"Who's there? Stop fucking around or you're next!"

Then, out of the gloom stepped Tesha. Her face was a mask of fury that made Helena want to crawl away as quickly as possible.

"Who the fuck are yo-"

"She is my plaything," Tesha cut him off and pointed at Helena, "how dare you lay your filthy fucking hands on her!"

"Fuck this, fuck you!" screamed the man-beast as he lunged at Tesha.

All Helena's bully did was snap her fingers and there was a sudden flash of flame and heat. It engulfed the figure lunging for her, knocking him clean off of his feet. His accomplice stepped forwards, fire wreathing his hands and a sheen of green in his eyes.

"Run," Tesha said quietly, her voice dripping with menace.

Helena's attacker scrambled to his feet and ran towards the hole his friend had made in the window. Tesha sent his partner in crime running after him. Satisfied they were gone she turned to Helena.

"How dare you!"

Helena scrabbled away from her in fright. The sudden realisation that she may have been safer with the fourth years. Tesha reached down to drag Helena to her feet by the lapels of her blazer, their faces almost touching.

"How dare you let them lay their hands upon you! You are my property, do you understand me?" she practically screamed in Helena's face.

The smaller woman began to shake like a leaf, her mouth opening and closing uselessly as she tried to process what was happening. Tesha grabbed Helena by the chin and forced her to look into her eyes. That now all too familiar flash of green filled Helena's mind as she felt her limbs go slack.

Bend over the workbench.

Heart pounding in her chest, Helena's body obeyed without question, her forearms resting on the bench and her ass facing Tesha. She felt as Tesha lifted her skirt up and took a hold of her panties. With a terrible tearing sound they were torn off. Exposing her chocolate pussy to her bully once more. Helena took a deep breath, awaiting the strike that would inevitably come. Instead Tesha spoke.

"What are these things?" Helena could see her as she moved to the bench next to her, "have you been making sex toys, little pet?"

Helena scrabbled desperately for an answer within her mind, how could she tell Tesha the truth whilst she was captured like this? But then the choice was taken from her.

Answer me or this gets painful.

For a moment Helena bit her lip, scared of what was to come. Knowing Tesha would make good on her threat she answered meekly.

"They were to help me against you..."

Helena screwed her eyes shut, awaiting the retribution that was to come. She opened them again at the sound of Tesha's laughter.

"You thought little toys could help you?"

Tesha reached behind Helena to place her hand on Helena's pussy, already growing wet as it was.

"No. It's not just because of my powers that I own you. It's because I own this. You'll never be able to shake off your place at my feet. Just accept it."

Emotions whirled around Helena's mind. She wanted to protest, to cry out and tell Tesha she was wrong but no words would come. 

And in that silence it dawned on Helena that for once Tesha might be right.

Despite being the pathetic little geek she was, no one bar Tesha ever bullied or mocked her. Given her bully's display with the fourth years she was beginning to understand why. There was no reason Tesha should have been assigned to her in the exam either, they were on entirely different courses, unless…

Any further rumination was lost at the sight of Tesha picking up Helena's very own shock crop.

"Though if you're having trouble accepting it pet, University is the perfect place to learn a lesson…"

With that Tesha flicked the switch at the bottom of the crop and electricity crackled into life around its head, illuminating Tesha's wicked smile. The crop connected with Helena's ample backside, bright energy contrasting with her skin and her world burst into pain. A cry left her lips, somewhere between anguish and excitement, her breathing coming quick and shallow. Already she could feel the welt forming, sensitive to the air. The next blow came in quick succession, striking the other cheek with expert precision. Helena cried out again, her voice echoing loud through the laboratory. Her eyes were wet with tears, the sharp pain was like nothing she had experienced and she was completely unable to block it out.

Yet part of her didn't want to, already there was the hot, sticky trickle between her thighs…

"I must say then little pet you have done a wonderful job with this, I'm excited to see if the rest are as good."

The next blow landed between her ass cheeks, landing just on top of her pussy lips with a wet slap. No scream came this time, her breath caught in her throat as wonderful pain flooded her system. Every muscle in her body tensed at once with the impact. In the moments after all that could be heard was the crackle of the crop and Helena's heavy panting. After that Helena lost count of how many times Tesha hit her ass with the crop. Over and over sensation bloomed within her until it almost stopped hurting all together. Her brain flooded with endorphins, her vision going black at the edges. Every fiber of her being ached. If not for Tesha's command Helena would have collapsed long ago. Now all she could do was stare blankly ahead with her mouth hanging slack jawed.

"That should do it..." she heard Tesha mutter from behind her, "now every time you sit for the next week you'll remember who you belong to."

Tesha tossed the crop back onto the bench and peered at the other gadgets laid out on it. Helena followed her gaze, trapped as she was, she would have no choice to what Tesha inflicted upon her. The thought brought with it an illicit thrill she tried desperately to ignore but it only grew when she saw what her bully had chosen.

The strap-on and the butt plug.

"There's a good little pet bringing this along when I'd told you to," she held up the strap-on before turning to the plug, "this though I'm very interested in."

She stood before Helena then as she slowly stripped herself naked. First her blazer fell to the floor. Then Tesha slowly undid her blouse, tied as it was across her midriff. Seductively she opened it wide, exposing her full breasts. This was the first time Helena had ever managed to properly look at them. Usually she was too preoccupied by Tesha's torment. Her skin tingled as she drank in the sight of her bully. Seeing Tesha's olive skin practically glowing under the lamp light, her tight stomach which let down to... 

Helena tried to force the thought out of her head. Her mind was a maelstrom of conflicting emotions and new realisations. She felt as though she would need a week just to make sense of them but the silken flow of Tesha's body kept restarting her mind every time a thought rose up. And of course, Tesha knew exactly what was on Helena's mind. Her bully winked at her, then slowly spun around before sensually wiggling her way out of her skirt. Underneath it Tesha was wearing nothing. With precise movements Tesha parted her legs and bent forwards. Her hands traced their way up the inside of her thighs, drawing Helena's eyes with them. It was then Tesha slipped her fingers between her lips and spread them wide. Helena could feel her heart pounding in her head as she drank in the glistening pink jewel between Tesha's legs. Strings of her nectar spanned Tesha's fingers that had Helena's mouth watering. 

“Look at you my little pet, look at how fucking desperate you are,” Tesha purred as she stood up, much to Helena's dismay.

Tesha strutted over to Helena, her hips swaying from side to side. She reached out with the hand that had been between her legs and smeared herself over Helena's lips with one glistening finger. Helena felt her eyes go wide in shock not just at the act but her desire to suck and lick the proffered hand clean. Memories flooded through her mind as Tesha moved to pick something up just out of her vision. Helena had been scared at each time Tesha had tormented her but each had ended in bliss; the likes of which she had never been able to match herself. She looked at each memory with fresh eyes, had she always been aroused at Tesha's mere presence? Or had her bully used her powers for it? Wracking her brain for answers Helena was sure that wasn't how Tesha's powers worked…

On your back, hold your legs spread for me.

Helena's body obeyed as always. Her eyes went wide with panic as her train of thought was cut off by sudden cold of the workbench's metal surface under her back. Her arms moved down lifting her head up slightly as her hands took a hold of her thighs. Slowly Tesha moved back into Helena's line of sight, the click of her heels on the floor the slow rhythm to Helena's humiliation. In one hand she held the plug and the other was the hefty shaft of the strap-on, now secured at her hips. Without breaking eye contact with Helena, Tesha slid the bulb of the plug into her mouth, swirling her tongue around it. When she removed it the plug was slick with her spit, a line of it connecting to her lips to which Helena could not help but stare at. As she stepped forwards one hand trailed along Helena's exposed inner thighs, sending shivers up her body. The other lined the plug into place.

"Deep breath now for me pet," Tesha warned.

Helena barely had time to register what she meant before Tesha slapped the plug home. She cried out in shock at the sudden intrusion. Without missing a beat Tesha trailed her fingers around the plug's base, making the muscles in Helena's legs twitch at the electric feeling of her touch. With a resounding clack Tesha's nail came into contact with the screen on the base of the plug and turned it on. The effect was sudden. The aphrodisiac gel it secreted hit Helena's system like a hammer blow. A low groan of primal arousal escaped her lips as the fire of lust bloomed deep within her core. She had already been aroused watching Tesha strip and now she could feel the wet warmth of her lust trickling down her pussy and over her ass. With another tap Tesha turned up the intensity of the device. It felt to Helena as though her mind was being washed away in a tidal wave of desire. Her every thought replaced with a craving to be fucked, to be used, to cum over and over again. If Tesha had given her control of her lips she had no doubt that she would be begging her to use that strap-on.

"Oh you should see yourself little pet, what a mess your pretty pussy is making for me. That glassy eyed dumb slut stare suits you well," purred Tesha.

She rested the head of the strap-on against Helena's slick, swollen clit and slowly ground her hips back and forth. Although the pressure was minimal Helena saw stars nonetheless. Her moans were so loud that it was a surprise no one had discovered them. She watched Tesha's wicked grin, the lustful glint in her eyes, the mocking smile as her bully teased her in a manner so intense it was almost cruel.

You may beg me to fuck you.

Not an order to beg, that was the worst part, just permission to do so. Time seemed to slow to a crawl. Tesha's strap-on drew back far enough that for just a heartbeat Helena was able to form a coherent thought. Now she didn’t have the deniability of Tesha's control. She had been given a choice. Did Tesha truly own her or had she forced Helena all along?

Then the heartbeat passed, Tesha's hips slid forward again and the answer was made. 

"Please... Oh my stars please just fuck me... I need it so badly… Fill me up! Make me yours!"

The words began to spill out of Helena's mouth in an endless torrent. Tears flowed freely with them through desperation or relief it mattered not. She had taken the plunge and there was no going back now. When Tesha shook her head and sped up the speed of her hips, Helena felt a wave of despair wash over her.

"Please Mistress. I am your superior, pet and it is time that you recognise that."

Helena couldn't believe it, even with her arousal forced higher than it ever should be surely she still had some measure of dignity left? Another tap against the plug changed that. Helena's whole body was aflame now, just the very air against her skin was too much to bear. She threw herself into the only option she could see. The one that now she knew she wanted. 

Surrender.

"Please Mistress, please fuck your pet. Please, I need it so badly. I need you."

That's better. You are free to move. You will stay still for me though.

Helena let out a gasp of relief as control returned to her limbs. Rather than fleeing though she did the opposite, pulling her legs further apart for Tesha. Her bully smiled and moved the head of the strap-on down to her eager hole. Helena wiggled her hips, trying to encourage Tesha to fuck her, her dignity tossed aside for the promise of sweet release. It was like heaven itself when Tesha pushed herself into Helena's wet pussy. Bliss filled her mind causing her to throw her head back and practically scream in delight. She was ready to cum just from feeling Tesha begin to fill her up. 

Helena kept her head raised so that she could watch the lustful expression on her bully's face as she gave herself to Tesha. Inch by inch Tesha claimed more of her. She could feel every ridge of the strap-on, how the curve of it hit that spot within her so perfectly. Experimentally she reached out with her abilities and turned on the strap-on’s vibrator function. Her back arched as the extra wave of pleasure hit her. Tesha took this as her cue to stop being slow and teasing and slammed the strap-on the rest of the way inside of Helena. Like a woman possessed she fucked Helena. Each and every thrust slamming into her and making her body shake. Soon it began to grow too much for Helena and the wave of pleasure overwhelmed her. Although her body shook violently with the force of her orgasm Tesha did not slow. In fact Helena watched the predatory look on her face grow more intense. Her hands took a firm grip of Helena's thighs, fingers digging in so that she could fuck her prey even harder. Helena's world was reduced to only her and her bully. The humiliation of feeling such pleasure at such a woman was entirely lost to her.

"Please, please, more Mistress. I need it..." she pleaded.

Tesha laughed, her hand flashing out to connect with Helena's ass. The welts were still sore from the crop and the pain was brought back in its entirety. Helena's cries grew louder, the sensation of pain only heightening the pleasure.

"You like that you little whore?" mocked Tesha.

"Yes Mistress..."

Tesha's hand connected with the sore skin again. Each time the pain felt not as it should, instead only as an extension of her pleasure. Each one drove her even closer to another earth-shaking orgasm. Each one leaving another red hand print that Helena would have marking her for days to come. Still she pleaded for more as Tesha plowed into her. Debasing herself further with each word uttered from her lips until they became one incoherent ramble. It was then that Tesha played her final card.

"Make it bigger."

Helena obeyed without even thinking. To her bliss addled brain the consideration of being gentle never occurred and strap-on expanded rapidly to its fullest setting. Her moan was ear-splitting in response and only grew in pitch and volume as Tesha increased the ferocity of her fucking. Helena had never felt so full in her life. The plug had already made her pussy feel tighter than usual and now this was beyond anything she could cope with. Once more she locked eyes with Tesha and for the briefest moment there was that insidious flash of green.

Cum for me little pet.

All around the room sparks flew as circuit boards and screens overloaded alongside Helena's brain. Every nerve in her body was alight with the feeling of complete and utter surrender to the pleasure that coursed through her. Her body shook with violent tremors but Tesha held her firm, not yet finished in her onslaught. Driving Helena over the edge repeatedly. Each one hitting her harder than the last. Each one made her lose a little more of her fearsome intellect.

In the end it was the sweet blackness of unconsciousness that freed her... 

—

When Helena awoke again she was alone and the dim light of dawn was shining through the glass walls of the laboratory. She was knelt on the floor with her head tilted down and arms behind her back. Inquisitively she tried to move but found herself held stiff in place. Although she could not see what was holding her in place she knew the feel of the leather cuffs well enough to realise that it was her own bondage harness that she was trapped in. The very one she had designed for Tesha, that only she could control. Confusion swirled around in Helena's mind as she reached out to the computer in the harness to free herself. It all became clear as she was able to stand.

There written on the inside of her thighs, in her own handwriting was written:

Property of Tesha.
