Nothing prepared the silver haired woman for what was coming to her. As far as she knew, she fulfilled the deal that was forced upon her. There was no way for her to know that she did something wrong. All she knew as the catalyst was unstable and so she made it stable. It was not her field of knowledge she was working with and not knowing what the catalyst was much less what it was used for did not help in the task. With so little information and experience, Vera had done all that she could to accomplish the unreasonable demands of the demon.

Sadly, that was not enough it seemed. But as far as she knew, she had earned herself at least some freedom from that annoying monster. The only warning the nude woman received that something was wrong was the door opening suddenly. "Tch!" Vera was already annoyed that she could not get a moments rest before another creature went after her. With a quick word and a flick of her wrist, she sent forth a bright flash of light towards the opening door. Perhaps it was just nerves or paranoia but she was certain that she locked her door before coming to the shower. Whoever was coming was obviously not a student.

The demon in a fit of primal rage made his invisible way into the bathroom right as a blinding light illuminated the doorway. His form though invisible under normal light was briefly outlined under the flash of magic energy. His eyes went white and then black as specks of color slowly returned from the edges. With a growl he went to rub his eyes with his hand. Wondering what had happened he remembered Vera's trick from their first encounter and felt his anger building that he should have been ready for her usual tricks.

As the blinding light faded he shot his tentacles to where he thought he had seen her last before the head girl had blinded him. Like looking at the sun too long he had to wait for his eyes to adjust and relied on hopeful wrappings of his four cock tipped tendrils...

The flash of light allowed the Head Girl to see the outline of the demonic invader. The nude woman quickly ducked to the side to avoid the barely visible tentacles. Gritting her teeth, Vera was getting very tired of this. "What is it now?!" she called out to the creature at the door, "I did what you asked and you said you would leave me be! Get out of my suite, demon! I do not have the time to deal with you tonight!" There was little else she could do. The creature would recover soon and really her magic would only delay the inevitable. The Head Girl crossed her arms infront of her chest and simply waited. She would not bother resisting further. This game had gone on long enough.

As the light created overexposure faded from the demon's eyes, he had apparently missed the silver haired vixen. He turned towards the sound of her voice, at his jaw dropped as he heard her denial of wrong doing but also the audacity to claim a job completed.

The demon roared in a vibration of frustration, You dare speak of wanting our bargain honored? You claim success when all you delivered was a waste of a precious material? You then think to command me... The demon lashed all four tentacles where he last heard the voice as the spots finally faded.

"You said to stabilize it so that is what I did!" she snapped back, "You told me nothing about the material I was working with, nothing! All I knew was it denonated easily so I used my magic to prevent it. I accomplished the task based on the information you provided me, demon! If you wanted something specific to happen with the catalyst, then you should have told me." The tendrils snapped against Vera's nude form. Pain stung across her skin, no doubt leaving red marks in their wake from the vicious assault. But the woman did not move and would not hinder him from his useless rage. "And yes, I will command you as you apparently failed in doing something as simple as give clear and direct instructions," she replied coldly, "Your vague information is what led to you losing your precious materials. No amount of hitting and fucking will change that fact."

Clear and precise directions were given, you failed to ask for clarifying answers should you have any doubts about what I had tasked you with... The demon said sending out his tentacles seeking to secure her wrists and ankles. Not only did you know the price of failure, but you delibrately lied rather than spend a night being pleasured by me.

The irrate demon found her form not running, nor flinching as she showed resolve towards her coming fate. The demon had no intentions of letting her delusions of events stow his plans on relieving his frustrations. The tendrils wrapped each arm and leg in a secure grip lifting her in the air they began tugging her lovely naked body spread eagle. Fucking and hitting, I guess you know the plan, so might as well rethink your stubborness, and maybe beg to pleasure me as you know how painful using you can be...

And with that he spun Vera so she faced away from him and pulled her onto his lap. The tendrils coiled her ankles locked together under his thighs, forcing her sex to press against his member. Slowly she would feel his member growing in size and hardness as she sat there. Her arms were pulled up above her head, her wrists crossing, while her arms extend.

So what scares you most about another evening pleasuring me? Is it the tail that hangs over your head? Maybe the slime ready to ruin your perfect hair? Maybe the painful and pleasurable orgasms I'm going to force out of your hot little body? Or is it that deep down inside you know you will love every blissful, wonderous moment of fear, pain, and bliss?

"You did not seem to mind losing materials when it detonated the first time, demon," she replied, "The only one lying here is you. I did as you asked and you even checked it yourself and said I did the job correctly. So I followed your so called clear and precise directions or else you would have never released me. If it was incorrect you could have just as easily told me what is wrong and I would have attempted to correct it then. Instead, you come barging throwing a hissy fit like spoiled child. Save me your excuses, you are here for no real reason beyond the fact you want to fuck me. So do not claim this is my fault that your catalyst does not work as intended."

The Head Girl was easily bound and brought to the monster's lap. She could feel the warm member growing and hardening as it remained pressed up against her netherlips. "Are you done with your useless taunts?" she responded, "Get your stupid temper tantrum over with so I can get some sleep. I am already behind enough on my work because of your constant intrusions and abductions." Her arms were left held above her head, leaving her lovely breasts revealed to the demon's eyes. Vera closed her eyes and waited for whats to come. Punished or not, she knew this was merely a monster throwing a fit. She had done nothing wrong but this was truly growing annoying. Unfortunately, being a Head Girl only provided her with some protections from the island's visitors.

The demon started doing a bunch of things at once. First, his head snaked forward, his lips encircling her left nipples as his tongue darted forth to flicker over the nub. His sharp clawed hands reach out, cupping her rear cheeks. His sharp claws drawing white lines of pressure over her backside. The points press into her skin, but not deeply or hard enough to draw blood, but enough to leave a hint of pain.

Try as she might her denials and reluctant victim would end in pleas of forgiveness, or in begging for his help.

The demon switch his mouth to her right breast, repeating the tongue tickling of the first. His hands grabbed her butt sharply and lifted, aided by the tentacles exending her arms, she was brought up and she could feel his raging member spring up to sit at her exposed sex. The lifting hands spread her cheeks and instead aimed the member at her back door enterance. She was dry and unlubed, and his intentions were made clear as she was lowered and her body weight began to return.

His teeth brought a sharp nip of her nipple before drawing his head back to look at her defiant eyes glaring out from under her bangs. You will change your tune...Would you like some lube or something to help you to relax, otherwise I can accept your admission of fault? He said as his dry member poked up at her anal ring, the weight making denying the eventual outcome a guarantee.

Shivers of disgust and perhaps arousal ran down Vera's spine as the demon's lips trapped one of her nipples and proceeded to lash it with his tongue. The helpless nub reacted to the monster's attention, pulsing with warm blood as it slowly grew erect. But the tingling pleasure was contrasted by the scratch of Slimer's claws over her back. The needlesharp points made it feel like she was being slowly cut open but no wounds were made just yet.

As the beast moved to awaken her other teat, the Head Girl was lifted into the air and guided over the monster's hardened cock. She was lowered slowly until she felt the hot unrelenting tip pressing against her tight anus. Vera knew this would be less than pleasant for her. The demon decided to inform her of her upcoming plight and try to force her to accept blame for the monster's failing. "I already explained what happened," she replied, "There is no fault for me to claim. Good to see your methods of argument are as brutish as your research. If your intention is to make me suffer until I accept the blame for your own mistakes, you are going to get nowhere quickly." Her body tensed sligthly at the sharp nip at her hardened teat but she did not open her eyes. She merely hung there in her bonds, expecting this monster to continue with this insanity

Vera the only insanity is you holding to your stubborn pride when you are as much to blame for the failure as you seem to think I am to blame. The only difference is that you are my helpless pawn to do with as I please. Denials and refusing to admit any failings on your part only cement your coming fate. He lower more and more of her weight onto the unlubricated tip pressing precariously at her tight anal ring. The pain and agony of the dry insertion into her rear would be undeniable, but the demon was livid at her continued protests of innocence in the matter.

Admit your trickery and this will go easier on you. I will take your admission or you can simply ask for my help to make this easier on you. I know you and your foolish arrogance Vera, so I will guess that you will never admit a mistake, but an even bigger mistake would be to let pride lead you to great suffering. We can make this easier and you admit your faults and I leave your ass alone for the evening. Your other option is to ask for a helping of my slime? Otherwise even that tight ass of yours wont be able to keep me out forever...

The demon taunts the trapped head girl, who keeps her eyes screwed shut trying to deny the demon any satisfaction. The pressure continued to mount between her tight opening and the dry velvety tip, while his tail pulsed filling with the green slime. The disgusting ooze familiar by now to Vera.

The demon smiled wondering if her bull-headed pride would bring her an evening of torturous lament, or if she would break character and in the intamacy of her quarters, accept her fault in the matter or beg his assistance. He fully expected the stubborn silver haired beauty to refuse, but the prospect of her dry ass being violated might make her see some sort of reason, that to her the demon simply lacked...

"Nngh!" she grunted uncomfortably as she felt herself be lowered again, the tip threatening to split her wide open. "I will not lie because you doubt yourself. The fact you ask over and over again proves you are just looking for an excuse. Torture me all you like, I will not admit to your foolish lies. Pride has nothing to do with it. There was no trickery, I did as you asked with the vague instructions you provided. Now either get out or finish with your temper tantrum. If the latter, I want to at least be able to see the nurse before I go to class tomorrow."

As she said, this has nothing to do with pride. This is a demon who just wants to blame someone other than himself. Its pathetic really but the only person who will know this is Vera herself. It would not be the first time a monster tortured her with the intention of causing her pain. But she will not sacrifice her integrity because a monster threatens her to do so. The truth is just that and no amount of ass fucking was going to change that fact from lingering in the demon's head. At this point, the monster was just looking for a free fuck. Trying to justify his vile actions only made the monster look even lower to the Head Girl.

The demon felt his warm veiny member pressed between her dry cheeks and realized if he gave in now she would hold onto her stubborness. Actually he began to think that nothing would change the fool girl's mind. Vague instructions? I asked you to use magic to examine the substance, not use it to make it useless. I don't remember ever asking you to make it useless... The demon knew that eventually he would penetrate her, but the thought of dry fucking her in the ass, with all the friction involved would teach her a lesson, but he didn't think that it would be pleasurable for either of them.

Perhaps he was taking the wrong approach. He lifted her up and pulled her close to him, relieving the tension that was placed against her ring. You still hold to your foolish stubborness. We'll see if that remains the case. You proved in the basement you had been properly trained to take a large cock in that sweet ass, so I'll fuck you later for fun. You are absolutely right though, you wouldn't budge for one minute. So I think I'll need to take something from you that you seem to care for more. With that he carried her to her desk, tentacles still comically holding her arms above her head while she rested on his lap. Looking at the desk he didn't see what he was looking for, so he opened it up and rummaged around inside until he found what he was looking for.

Using the tentacles, he picked her up by her arms and spun her around so her back rested against his chest. Then, he grabbed what he was looking for from the desk and returned to the bathroom, stopping in front of the mirror so she could see her lovely form sitting on his lap.

You seem to take great pride in many things. You strive hard in your academics. You perform your functions as a headgirl with a singular drive. You dress emaculately. You always look perfect. While I can't ruin your grades nor can I remove you from your head girl position. Ruining your clothes won't do as they would simply be repaired or replaced by morning. The demon says holding his arm in front of her to show what he held while his other hand reached around her form to pinch her nipple to make sure she was paying attention. In his hands he held a pair of scissors.

Your lovely hair though, now that is something you seemingly have worked hard to grow to reach the length it is and must take pride in it as much as your image. Sliding his fingers through her hair just behind her bangs, he ran them down gathering it as he went. He managed to gather all her hair into a hand behind her at her shoulders.

If you wish to repent for ruining what I cared about, that you broke the arrangement, I will hear what you say. If you want to protest your innocence, then I will have to ruin something you care about. Taking the scissors and snipping them opened and closed a few times...

"Once again, you selectively omit facts to try and hold up your useless argument," Vera replied calmly, "You stated I was to examine it and change it magically to make it as stable as possible. I did both. I analyzed it and made it stable. You stated no further information beyond that. You did not tell me what the purpose of the catalyst was or if there were any aspects of the catalyst that had to remain intact. Apparently you know nothing about the basic rules of science. Analyzing a new material generally involves destroying part of or the entire sample in order to gather the most possible data. Without such methods, geologists would not know much about the minerals and elements that make up Earth."

Even as she was threatened with being reamed up the ass, Vera remained professional as one could be while still nude from her shower. Having worked in the unforgiving world of business and corporations, knowing and remembering deals to the letter was only natural to her even if it was a verbal agreement. So either the demon will ignore the cold hard facts or he was not capable of remembering what he forced Vera to do in the first place. In either case, it was not scoring any points for him in Vera's book.

She was carried off to the other room and sat before a mirror as the beast found some scissors. The Head Girl had to resist the urge to roll her eyes as Slimer threatened her once more to admit fault. It truly seemed as if he was growing desperate. "Your whining is wasting both our time," she stated coldly, "And now you have reduced yourself to the role of a bully. The fact you are on this planet I can assume you had at least grown out of such things. But, if its what it will take to prove my innocence so be it."

Both her wrists bound together allowed the woman to clap her hands and chant a quick word of magic. Once more, a bright flash of light would flash, hopefully blind the creature as the flash would also reflect of the mirror they were infront of. Vera would attempt to free her wrists from her bonds long enough to do what she intended to do. She was not going to flee as that would be pointless as all the creature would have to do is wait in her room until she returned. Instead, if she free her hands, she would chant another word of magic while the creature and herself were blinded. Another much smaller flash of light would occur and Slimer would feel the woman's hair suddenly give. Vera would hop of the monster's lap, rubbing her eyes as she sighed in annoyance. She did like her long hair, but such things could grow back. This was an age of science afterall. Her hair would be barely at her shoulders with her bangs being slightly longer.

"You break into my home with a case that is held up in nothing but ignorance and threats. Any lawyer in the galaxy would have chewed you up and laughed you out of court with how poorly you presented yourself, monster. I completed the contract as you asked and your only counter argument was calling me stubborn for accomplishing your request then threatening my well being. For someone who claims to know science, you fail to know the basic methods of analyst. Science revolves around failed hypothesis and beginning anew. Not throwing hissy fits because your little shortcut failed to deliver in the way you wanted it to," Vera sighed, "Are we done? I will need to report to my superiors that the hair they enjoyed has suddenly be cut short. And I grow very weary of repeating myself to someone who refuses to listen. Or are you just going to keep threatening me with further harm in hopes I give in to such childish tactics?"

As the tirade took place the demon felt his anger grow. She seemed content with battling him not physically but with her sharp tongue. He had told her what was coming but as the flashes of light faded she was standing before him. In his hands he held the majority of her long hair, the silky strands draping over his wrist, while she continued hurling insults.

The demon had about enough of the arrogant human girl. As his rage built, he found his control slipping away. As it went, he found himself staring for brief moment at the nude head girl before him. His hand flashed out, the backside impacting with her elegant face. The crack of the hit had her silver shoulder grazing hair fluttering as the impact spun her around towards the desk the mirror sat behind.

Quickly he moved forward. His vision went red as this lowly human with centuries of discoveries to go before her race even dreamed of being equals in the sciences, tried to lecture him on catalysts. As she fell against the desk he grabbed a wrist, twisting it behind her back while his tentacle shot forth racing under the deak and coming up the far side. Quickly, it coiled the wrist and pulled her over the desk.

Trembiling with rage he yanked upwards on the arm twisted behind her back. His other hand found a grasp on her newly shorn hair after dropping the pile of cut strands to the floor. Forcing her to look in the kirror his rumbling voice came out exceptionally low like rocks rubbing together, I think you forget your place, and a reminder is past due. A catalyst has to be reactive otherwise it is useless, much like your attempt to berate me. I have forgotten more about chemistry than your limited race can even comprehend.

He was directly behind her, hand yanking her head and arm back so she was forced to look into the mirror. Vera was forced to see that despite her restrained magic, she was nothing more than a beautiful young woman, bent over a desk. Her future was the whim of the demon aligning his cock behind her, one that she had just made extremely angry. The red mark where his hand impacted her lovely face was beginning to show as she was forced to stare at her own helpless form about to be rutted by the monstrosity behind her.

Without much time to anticipate what was happening, the demon thrust forward with his hips, sinking himself inside her dry pussy. The size combined with the dry friction, would make the penetration extremely rough. Head girl or not, you need to realize when to shut your mouth and when to open it in apology. You young lady are still nothing more than a human. Its only through intervention of those much more powerful than your pathetic race that you entire population doesn't live as slaves to do the bidding of those far more advanced than you can imagine. I think you need a complete reminder of your role here and what is expected of you. So unless an apology is forthcoming, its time for your lesson in chemistry and humility...
