The demon was lost in bliss as she took him inside her warm wet mouth. It was as if his essence was wrapped in pure pleasure, time slowed and he closed his eye as he felt her work that muscle in her mouth to perfection. And then she stops to remind him of knots, and he briefly snaps back with a groan.

While he certainly could meditate and focus his mind on the lessons he had imparted upon her, Daphnee's slow erotic pace was not enough to drive him to his boiling point. Slimer simply was enjoying his reward and had no intentions of driving himself to cum, before that goddess on her knees forced it from him. He simply relaxed and enjoyed the wonderful journey of absolute bliss she began to take him on. Her lovely hand spread and her deft fingers gently began rubbing his balls. It simply didn't get better than what Daphnee offered with tongue, lips and hand. Slimer was simply in no rush and would accept this trial for as long as Daphnee intended to hold court.

That goddess though certainly had a devilish side it seemed. Just as he was indulging in the sinful pleasures of her tongue, those warm licks seeming to penetrate him to his soul, they suddenly halted.

She drew that amazing mouth back, and instead of showing him more delights from the fantastic art of the blowjob, she seemed ready to orate on someone. The demons groans into that gag halted, and he looked down into her eyes as if asking "are you serious?"

She seemed to have a plan though and if driving him wild with anticipation and longing was a part of it, it was working well. Her lovely tongue danced over his sack, driving more pleasure home, as if she were a vampire hunter armed only with stakes of happiness, yet she resumed her tale, with promises that he would be content with the outcome. Patience was one of his strengths, yet at that moment, his mind did seek out the knots, for if he didn't, he feared he would be tempted to rip the metal brackets free from the ceiling to simply rape her mouth.

As she began the tale he formed a knot inside his minds eye. No, not an ordinary ten, or even twenty twist knot, but one that would have competed for most intricate knot ever tied in the history of life itself. As he began to work at it, pulling here, tugging there, he wondered if it was a little on the small side.

“It is really a legend rather than historical but one based on a real historical figure.” She shrugged and grinned as her finger still coaxed the tip of that engorged cock. “It deals with the puzzle of the Gordian Knot, an intricate knot so detailed that it had been prophezised that the person who untied it would go on to rule all of Asia.

“While this situation is similar being gagged you can't exactly beg but I doubt you are powerless I'll let you ponder his solution for just a bit if you're not already focused on the subject of knots.”

She leaned forward washing his balls with her tongue as she gently stroked his cock. Mindful of any throbs she would back off if she judged she was getting too much of an effect. That aim was to grant him pleasure without release.

When she had to brake off contact or a few minutes past she crawled around him to his back. Ania seemed sensitive with her tail and spine so she used one hand to run along his tail to determine that reaction as her tongue moved against an ass check. Raising higher on her knees she reached around him to stroke his length slowly and just as carefully until she received the first hints of excitement. Again she ceased what she was doing got to her feet and wandered to the shelves.

Returning in front of him she had a silver colored dildo and approached, sucking on it while tracing a finger down his chest until it arrived back at the erect tip of his shaft. Her intentions with the dildo had been a bit unclear though her lips slowly worked over the toy. Green eyes watched him.

Before long though she broke away stopping maybe ten feet in front of him. She still sucked on that dildo, her green gaze focused on his rod as one hand unzipped her skirt. She worked it down, then her panties before sitting down and spreading her legs for the benefit of his view, that toy working around the edges of her labia as the other rubbed her clit.

“Mmm … ahhh ...” Her hips rolled, that toy teasing around the edges of her sex. “Oh, I should finish that tale. Did you come up with the solution or did you wish for me to tell it to you?” Of course he could not answer with words so she was mindful of other signs as she aligned that toy against her entrance ready to insert it into herself.

Daphnee paused, and gave him the shortest possible version of a trial for what was one of her planets legendary conquerors. Were it simply a conversation on history, the demon would have been fascinated, and probably wished for her to regale him with the lengthiest version that she knew. Chained, gagged, and teased, he wished that this Alexander guy had never been born. He almost lost his work on his mental knot as she intimated that she knew were his focus had escaped to. Damn she was a good study.

As wonderful as she was as a student, she was simply unbelievable as a tutor in the fine activities her tongue began to perform. His balls were graced with a fresh round of solid licks and kisses. He hand continued to masterbate him, working in unison with her mouth to keep him rock solid and in a land of bliss. She seemed quite capable at easing up as his pleasure built. That ramp towards an orgasm seemed to have transformed into no more than long acute slope.

She paused again, much to his disappointment and crawled past him. Slimer felt her lips kiss his ass and a few ironic thoughts jumped to mind, as her hand sfokes his thick bulbous tail used to slime his victims. While it didn't feel bad, the large appendage was developed for purpose and lacked the sensativity even his tentacles possessed. While they felt as sensative as a human finger, his tail had the sensativity of a rough heel.

Soon she left and returned with a silver dildo, placed between her sexy lips, and the demon almost chuckles as realized he was jealous of a piece of plastic. She strode away, pausing long enough to slip out of her thigh and ass accentuating black skirt. Soon to follow were her lovely black panties. It appeared she intended to give him one hell of an erotic show. His cock almost stiffened more, if it were even possible, at the mere thought.

Moans of pleasure escaped her lips, as she began working that toy around her erogenous zones. Pausing moments from insertion into her womanhood, Daphnee appears ready to continue her oration on the historical leader.

She observed him, saw that longing for this that he wanted his own member so enveloped in the heat of her body rather than that toy. She could see the bob of that member as it pulsed with each beat of his heart.

Daphnee felt as if she did an adequate job thus far in pushing him close to that edge though he was not there yet. Maybe he was and she was misreading the situation but she tended to be good at studying things and determining much from little.

After all she had a basic understanding of the fate of the students here though she had not been able to discern all the details she understood the end game. That was gleaned from a small piece of information whereas she had more here.

But she waited as she processed the scene before her, an unusual one for certain. Her eyes flicked to the chains hearing them rattle a bit but they held. He wasn't attempting to brake them but even the smallest movement made them rattle.

Then she dipped her focus to rest upon his throbbing member. The tip of the toy barely penetrating her before she returned it to teasing, rubbing her clit in an up and down motion.

“UH!”

But for now she held off on that solution giving him more time to work it out. She really didn't think he was focused on that though as she deliberately attempted to distract him. The toy worked it's way back inside her soon. Shallow thrusts though each had been at a quick pace.

She moaned out, her flower more then ready, displaying all that moisture. The toy advanced deeper but slowed down the deeper it went. “GAWD!” She gasped out. “D-DEEPER! You want to see it deeper?”

She teased that toy into her, drilling it into her now as she continued, her tits swayed with each movement as she jabbed the toy inside her. All in all the toy was smaller than he was though not by much. There were a wide arrangement of dildos of various shapes and sizes here, even one or two experimental models from NICE though she had not played around with any of them yet and thus didn't select them out of a whim.

The demon helplessly watched as she kneeled there, holding that love toy up to her opening, moments from insertion, when his concentration on the mental knot broke. How he longed to be the one precariously close and seconds from sliding inside her tight, wet womanhood.

Daphnee's pussy was almost pure perfection. When he was inside her wet cunt, it was as if her love tunnel had been created and molded into perfection, solely for the purpose of being fucked by the demon's hard cock. She was a considerate lover, able to not fear that large beast, as he savaged her, not tensing but enjoying all he had to give.

Then, it began, he was watching with those an intense emerald stare, as she sank that toy in, one single heavenly thrust inside her waiting vagina. She went, deep, hard and fast, slowly as the tip neared the limit of her depths, cervix not far away.

She asks if he wants to see her go deeper, and it seems as if he nods both his heads simultaneously to the question. His spiky haired head rocks forward and back, his eyes glued on her glorious body being used feet away. His cock throbs with desire, eager to be in that toys place, bouncing slightly.

Her lovely breasts swayed and bounced with her movements as she worked that dildo hungrily inside her sex. Helpless to remain watching the chains shake slightly as he inadvertantly shuffles his lower half forward a little before remembering his predicament. Sighing behind the gag, inaudible to the masterbating beauty, he settles in to enjoy the show, no knot needed, simply patience and willpower.

Ok so at least the demon had patience going for him. Had she untied him, he probably would have been unable ro help raping her until a few hours past when she passed out from exhaustion. He might even have slowed down or stopped at that point.

She noted the reaction of course, knew that he was getting closer. She had often used that aphrodisiac on other students only to deny them and test their needs until they had reached their limits. She didn't think that the aphrodisiac had any effect on him but the situation was the same.

He nodded at the question she asked and noted how he even shuffled forward a bit before realizing his predicament. She had been playing with fire more or less, she knew but at the same time it was what he had wanted and she complied.

The best option to her hadn't been inflicting pain or sexual torture but to tantalize. There were a few things that could be useful and she was well aware that words were unnecessary in order to beg. Body language was a factor that one could read and infer, though she continued to play.

Her gaze dashed to a shelf behind him as if looking at something then back to him, namely that engorged member. “Sorry, Looks like this one is the biggest, with the exception of yours.”

It was a lie, while at this distance it was hard to tell sizes she had worked in these rooms and knew of the wide assortment of sizes to be found. Still it wasn't exactly a lie, she could assume there were bigger ones and she wasn't in the mood to go check right now. It was more the point that she wished to emphasize that if he wanted to see something go deeper then he would have to make that happen.

But she had not stopped, that toy continued to vanish inside her producing moans from her lips. She varied things up too with different speeds and angles slowing down when she felt close or speeding up when release seemed distant.

A hand came up to squeeze one of her own bouncing tits. Her thumb and index finger captured a nipple rolling it back and forth. Right now it turned into a game of patience. She was in no rush though soon if he did not work out that solution she would play with him a bit more before moving on to the next phase if things progressed that far.

The demon's hard cock remain still pointed at her as if choosing its target. The demon watched as the show went on and he didn't merely want to fuck Daphnee, he craved to be inside her body. As she looks around to comply with his wishes she tells him that only he could reach deeper, not as a challenge but simply a sultry implication. Kneeling there she rocked. Her hand playing with her perky nipple and massaging that wonderful tit. His own hand clenched in desire.

Daphnee's other hand worked that toy rapidly, and slow, depending on her needs, inside her tight sex. She used different angles and moaned her delight as the toy streched some spots while rubbing others. It was as if he were no more than a peeping tom, peering through a window as a woman pleasured herself.

Not content with merely watching yet helpless to do more, the demon simply took deep breaths, wondering what other naughty sights, sounds and smells would he be forced to endure before he could take no more.

She had taken his challenge of this game and decided to show that she not only played it well, but perhaps was a master.

And she had noted the clenching of that fist, green eyes drawn to it as she heard the rattle of the chains at each movement. He was breathing harder but still not there. She couldn't help but grin even if she didn't intend on that. She did amp things up a bit though.

There was one thing just seeing though he had more than one sense. And she played to that know.

“OH GAWD!!! FUCK ME DEEPER!!! HARDER!!!” That toy attempted to go deeper but really couldn't. It was going faster though and the sounds of it filling her moist sex could be heard, just barely beneath her cries.

“GAWD … GONNA … GONNA ...” Then she stopped. When she started again it was a few slow strokes before she set the toy aside with a gasp. For a few seconds she laid there as if catching her breath but it wasn't long before she crawled back towards him.

She had worked herself up then slammed on the brakes before release. She yearned for that release but this time had been for him. She seized his shaft, careful to grab him at the base and gauged how sensitive he was before licking carefully at his balls and even gave that shaft a few licks.

Green eyes watched him though, her hand and eyes serving as judge to all this only taking a moment to look at the shelves behind him.

“You wanna cum? You wanna fill my sweet pussy?” She went back to licking his balls not expecting an answer not in words any way.

Closer and closer. Daphnee plunged that toy home inside her tender little pussy, driving herself closer and closer to climbing that mountain of pleasure, and leaping over the top, into sweet release. Her sweet voice crying out how she wanted it, how close she was. Yet, with inhuman control she simply halted. The aroma of her activity filled the air and the demon's nostrils, it was the sent of lust, the scent of sex, the scent to drive the demon wild.

While her erotic ballet for the senses was incredible, she gently grabbed his cock at the base, as if fearing an eruption at any moment. While the demon was beyond aroused, no show, not even that insanely erotic one, was going to have him cumming without some physical stimulation. Daphnee decided to test the waters by giving a couple quick ice cream cone licks to his balls, followed by a couple quick licks to his shaft. The show had made him hornier than hell, yet the gag refrained his answer. Her tongue with only those brief licks, would lap up quite an amount of pre-cum from his split.

Nodding vigorously, he answers her question with groans and garbled speech, muffled and contained by the gag. Whether he was answering her question about cumming or filling her sweet pussy was unknown. Yet, in truth it was both. He wasn't quite begging, yet he wasn't far off. He knew she was primed, yet his motor was set running by her display, it was a lesson in deprivation.

She had considered his response briefly before setting aside that soaked toy. As she stood up pressing against his chest with her bare one show he could feel her nipples against him, so hard and throbbing. Sinking two fingers inside her core those green eyes pressed closed, her face contorting in pleasure.

Then she slipped that gag down so it was over his chin offering his the treat that coated her fingers if he had wanted it.

Her leg hitched up over his hip as she jumped up grabbing his chains with her free hand to give her a bit of height. Slowly she angled herself aligning him against her, feeling that shaft against her. She knew she had to be careful here swishing her hips from side to side to tease that tip even more.

“If that is what you wish.” She lowered herself carefully as she slowly devoured that rod. When she took it all in her offered fingers would retreat. First, unless he took advantage of that brief bit of freedom his mouth had she replaced the gag. It was slow work with just one hand. Once that was done the hand grabbed the chains to assist the other in pulling herself upward just as slow. She had to stop a few times, he probably thought she was adding to the teasing nature of matters but she was not too athletic and needed to pause but even she could manage a single pull up which this essentially was albeit slowly.

But she drew herself off him completely hoping back down. Just a single thrust, it was maddening for her seeing that she had brought herself close already. Her gaze flicked to that member, then back to him.

“Wouldn't want to do too much though, no sense in getting you to cum before you ask for it.” She grinned though again looked to the ceiling where those chains had been attached before setting a single finger against his chest running it up and down. “Perhaps … I wonder if we have anything of that sort … I don't think so but ...”

She left him there getting a sudden idea and heading to the shelves to search. NICE had been into bizarre things so she couldn't say and she never had need to look before and did not remember seeing it or anything like it.

The demon certainly had no desire to lose this particular challenge, the chance the ravage Daphnee in a room designed for bondage, pleasure denial, build up, and release, seemed a prize worth struggling for, yet his willpower was fading as she teased his senses.

Sight, by making him watch her prime herself, pleasuring her body, making her pussy wet. Sound, making him hear her erotic moans and cries. Touch, as she licks his cock and balls tantalizingly before sinking his cock in one slippery tight descent to the core of her warm depths, wiggling and squeeze her way off, her vaginal muscles squeezing tight as she climbs back off. Smell, as she climbs close her natural aromas mixing with the scent of sex her her excited pleasure box. Finally taste, as she takes those fingers dipped in her amazing sex and placing them over his tongue, that muscle flexing and licking her fingers and his lips suck them dry.

Don't stop, is all Slimer manages as she takes his length completely, only to be regagged prior to her maddeningly evil dismount.

His was on edge, half ready to rip the chains free of their moorings in the ceiling and ravage her all night, but he was a demon of his word and a bet was a bet, at least for now. He tried to remain calm, his long cock fully engorged, pointed towards her face, his desire to fuck her raw readily apparent.

Yet the game continued as a finger slipped over his steel chest. She looks around, her short hair swinging as she quickly turns and heads towards some shelves, apparently a new idea in mind. His bulging biceps flexing as he mentally tries to calm his raging horniness. So far she seemed intent on making him boil, and not advance towards release, a tough way for her to easily win, but he knew she was cunning.

She had suddenly recalled that she had asked about his aphrodisiac affecting him before. In the library, of course, her mind had been a raging sea then. As it had been now though she had been tasked with a single objective. Naturally she could not win as long as he remained gagged though she had a plan. She was a cook in her spare time and understood that some things needed to simmer for quit a bit. Now if he didn't rip free of those restraints first. Time would tell.

“Oh, I never finished that story about Alexander,” she teased moving off towards the shelves behind him. She continued to speak as she searched the shelves.

“When faced with that knot his solution had been unique. Everyone before him failed to unwind this impossible knot. You know what he did? He took out his sword and cut it unraveling the knot. He went on to conquer the known world. That part of the tale is true, the entire knot stuff is questionable. I don't know who came up with it. Oh dear ...”

Moving back to him she stood in front of him realizing something. Sometimes the simplest solutions were best. That tale told her that. She pulled that gag down again standing up on her tippy toes as she dropped her voice.

“Will you beg for your release?” She didn't think he would but it was so simple she had to ask. Then her lips seal around his mouth, her tongue entering it and dancing against it briefly before she pulled away yet remained close, pressed up against him with a hand coiled around his member pumping it softly before glancing back to the shelves she was just at already anticipating that he would do no such thing as she planned out her next avenue of attack.

The demon certainly was aroused to no end. He watched as she bounced around apparently still in search of something in particular. Continuing she told him a story, he wasn't sure who this Alexander was, but he did like his style. Sometimes simple and to the point was the best approach. She returns and finally pulls out the gag, give him a passionate kiss his tongue seeking hers as they wrap and caress all to briefly.

She then asked for his surrender.A fair question, he starts to reply as she slender small hand grabs his hardened cock and pumps her slender arm, stroking him, ahhh....you certainly don't pull any punches... she continues looking around, and his arms flex, considering breaking the binding chains, but he calms himself as she stopsI very well may beg for release, but I certainly don't see a need to lose our bet just yet.

He gives her a wink, Sometimes simple is best, but creativity can solve the hardest riddles. You may be winning the battle so far sexy, but the war is far from over...

He wonders what devious attack she had up her sleeve next. The challenge was that all the devices in the basements were designed for drawing maximum pleasure from female students, not quite so for huge demons. But he did not doubt her ingenuity.

“Can't fault a girl for asking my dear Gordian Knot,” that hand stops pumping and she fixes the gag back in place before moving back to the shelves. Ignoring the implements of pain she considered her options. Nothing that could bring harm. The aphrodisiac had no real noticeable effect though she had noted how he had reacted to other senses being attacked.

Returning to his side she traced a hand over the ropes that covered over the spots that those tentacles were at. Rising on the toes of her boots her tongue traced behind an ear. If he looked he would see a palm full of powder in her hand. Now see had no idea if this would work, she often combined it with the aphrodisiac.

It was a substance that had frightened her yet she had learned how to wield it. Initially she had excluded the use of drugs from her repertoire in an effort to unravel him herself but this had the effect that she was looking for. There was no TV at hand, she lacked video anyway for what she had in mind.

The powder, which she blew into his face, produced convincing illusions in the mind. Images, sound, even touch and thermal components. It was real and she found that she could control what the victim saw to a limited degree.

By speaking she could tell a story that translated to the subconscious shaping what was seen to an extent. She never did have full control of what was experienced but she could steer it to a degree and that was what she was planning on now. It might have been cruel but it did no harm if it worked at all.

She found that the visions lasted a short time and had been activated once she set a scene in the mind of her target. She had even learned that they could end prematurely if she commanded it. It was much like hypnosis only better.

Dusting her hands off she leaned in closer to his ear. “I'm going to tell you a story. It begins the very first day I arrived here. Mister Timmons and I went to a beach. Can you see that? Waves lapping at the beach. Me in a green two piece bathing suit with my black wrist bands on. Oh, and Mister Timmons was one of my dolls,” she added. “Can you smell the salt? Feel the heat? Makes you want to go cool off in the water, doesn't it?”

She had tried to shut off the particular memory. She had to an extend not remembering everything clearly but that was not important since it was his mind that would see those images … or not … her hand drifted back to his member feeling his pulse as she slowly traced along it as she spoke.

The demon waited as she returned and leaned in close, and replaced the gag. Daphnee's hand appeared to be filled with a sandy substance, yet the particles were much finer than ordinary sand. The soft, soft, wet touch of her tongue traces behind his ear just before she blows that sand in his face.

She decides to tell him another story as images begin to appear in his mind. Daphnee stands on a hot beach, her sexy body barely covered by a two-piece. Her ass was less covered than covered and her perky breasts stood out against the soft thin fabric. Her hair blew around her face as her green eyes looked at a puppet in her hands.

The waves continue to lap over and over soothingly against the sandy shores of the beach. Such a hot day...a refreshing dip would certainly be nice, Slimer thinks.

Meanwhile pleasure rushes through him, as her delicate small hand slowly squeezes up and down the length of his stuff, engorged cock...
