"Ooh?" Ryujin hummed when she protested to his finger in her ass. "If you have the nerve to object, then this must really hurt or..." he paused as he ceased his stimulation of her wet pussy to test her reaction, "...this must feel really good." he continued as he began to thrust his finger in and out of her clenching spincter. "I remember I stuck my finger up your ass that day on the beach but you didn't say anything. I guess you were enjoying the ride on my cock too much to notice."

The blue dragonian continued to pump his large, clawed digit in and out of Naoko's hot hole as she licked his honey drenched hand clean of her sexual fluids. As she did, his tongue slipped under her shirt again to assault the cherry pink nipples, curling about one and lashing the tip across the rigid bud before moving on and doing the same to the other.

As Ryujin's tongue teased her hardening teats, his glance strayed over to the blackboard, noticing the lingering writing of the previous teacher. The message struck Ryujin with a wicked idea for the whimpering, hawaiin girl. When she had finished licking his hands clean, he pulled his finger from her ass and tongue from her tits. He pushed her back a step and rose form his place on the floor. He stared down at Naoko and licked his lips, "Undress. Take off everything except the skirt and climb up onto the teacher's desk."

Naoko groaned when the scaly hand retreated from her dripping sex and cried out as the thick finger violating her rear began to roughly pump in and out. She writhed and thrashed, the discomfort and humiliation somewhat dulling the lust that lingered in her nubile young body.

She struggled to focus as she cleaned the beast’s hand, and as his tongue snaked beneath her clothing once more to lash around her rock-hard nipples she groaned. The pleasure helped to take the edge off of the particularly unwanted violation of her tight ass and her soft tongue began to work more quickly.

When she finally cleaned the last drop of honey from his fingers she stumbled slightly, knees weak, when the dragon pushed her back. She trembled when he towered over her, eyeing her hungrily. When he ordered her to strip she hesitated, but didn’t dare refuse. She made her way over to the large wooden desk, leaving a trail of clothing behind her. First she slipped off her shoes, then paused to remove her socks. The hem of her skirt rose as she bent over, unknowingly exposing her wet, pink pussy lips to the dragon behind her. She stopped again when she reached the desk, looking nervously back over her shoulder at her tormentor. The desk wasn’t nearly as far from him as she would have liked, but the last thing she wanted to do was anger him. She undid the last few buttons of her shirt with her back towards him, and bit her lip as she let it fall away from her body, exposing her gorgeous breasts to the cool, air conditioned classroom. Slowly she climbed onto the heavy wooden table, and turned to face him, sitting back on her heels and hugging her slender arms around her chest to protect herself what little she could from his ravenous gaze.

Ryujin smirked as she obediently disrobed before him and climbed onto the desk, turning to face him yet still desperately trying to shield herself from his gaze. He walked over to the desk, eyeing her petite, exposed form and reached behind it to open a drawer. From that drawer, he removed a coil of treated hemp rope, "I think you'll enjoy it when I use this." he said holding it in front of her.

"Raise your arms above your head." he said as he looped the rope behind her neck, moving her hair out of the way so that the rope was in contact with her silky, amber skin. He tied a knot just above the top of her breasts and then looped the rope around her torso underneath her heavy tits so that it pushed them up a bit. He tied another knot behind her back, lining it up with her spine. He looped the rope around her torso again, this time above her breasts and pulled the rope tight before joining it with the knot he had tied abover her breasts earlier. "Now turn around and put your hands behind your back, forearm over forearm." he ordered her. He moved her hair over her shoulder to keep it out of the way and used the remaining length of rope to tightly bind her hands behind her, being careful not to tie the rope too tightly.

Ryujin stepped back and looked his handiwork over. The blushing girl's breasts were now jutting out proudly, both from the rope and the position of her arms. He had fixed it so that both her arms and her impressive mounds were connected so that whatever she tried to do with her arms would add more tension and pressure to her bound boobs. The rope itself was also quite course. It had been treated so as not to damage the skin, but still cause quite a bit of discomfort to the one being bound with it.

Ryujin turned her towards a full body mirror on the wall so she could look at herself, "What do you think Naoko?" he said as he ran his right hand up her thigh and under her skirt to tease her slick labia.

Naoko eyed the rope fearfully, but although she hesitated, she still raised her slender arms when ordered to. Her heart raced as the draconic beast wound the rough cord around her torso in an intricate configuration. She whimpered when he finally tied her arms behind her back, and tested her bonds as he took a step back to survey his work.

The semi-nude student twisted and turned, testing her bonds, the tightly wound ropes rubbing against her flawless skin. She let out a hiss of discomfort when a tug of her restrained arms caused the cords to constrict around her supple breasts. The ropes were rough against her soft skin, and all her struggles seemed to do was increase the friction.

Poor helpless Naoko couldn’t help but stare at her lascivious state when Ryujin turned her to face the large mirror. A deep blush colored her lovely face, and her firm young tits looked even perkier than usual thanks to her bonds. Her breathing was still slightly ragged, causing the impressive mounds to rise and fall rhythmically. Her little pink nipples remained stiffly erect, though there was no way to tell whether it was the result of her earlier torments, or an effect of her current state.

Already she could feel her submissive nature getting the better of her. There was a strange thrill to being tied up, knowing there was nothing she could do to stop the beastly creature from using her helpless body in any way he wanted. Not that there was anything she could do when she wasn’t bound, but the ropes seemed to heighten the eroticism already permeating the situation.

Naoko turned her gorgeous face to the side, blushing anew, unable to look at herself as the dragon stroked her thigh and teased her wet pussy.

(Sorry for the delay. I've had a huge case of writer's block recently.)

Ryujin captured her jutting left tit in his free hand as his other continued to play with her sopping slit. Dark blue digits sank into the creamy amber flesh of her rounded orb, palming the hard teat at it's peak as he kneaded her breast. "Well?" he asked, "Don't you think the rope suits you? It does a wonderful job complimenting your chest. They feel so big and perky, and your nipples..." he said giving it a pinch, "... they're like diamonds. And your pussy is absolutely drooling." he said as he pushed his fingers into her again.

He grips her head and forces her to watch him finger her tight cunt, "Don't look away you little slut!" he hissed, "We both know how much you enjoy this. I remember how much you loved it on the beach, when I did this." he said, pulling his fingers out to cruelly twist a taught nipple, "...you like being hurt you little nympho. That's why you came so hard before. How did it feel being raped in front of your entire class? You got a thrill out of it didn't you?

Naoko's soft, full lips parted and a low moan escaped as the dragon began to stimulate one of her supple breasts. She immediately bit her lower lip, mentally cursing herself for letting her tormentor overpower her will so easily. She couldn't help it though. It felt so...good. Her stiff nipple felt the bumps and ridges of every scale on the beast's hand as he rolled and massaged the large, soft mound. She could feel another flush cross her cheeks as her dripping pussy began to contract every so slightly around the thick digits teasing it's hot, wet depths.

She whimpered but didn't resist when Ryujin forced her to look back into the mirror. Her silky smooth thighs were splayed wide, giving her a wonderful view of her slick wet folds as they were plumbed by the dragon's fingers. Her laughably useless skirt was bunched up around her waist, a cruel caricature of the modesty the garment was suppose to provide. She cried out as her stiff pink nipple was twisted, but the scream quickly degraded into a lusty moan. His hands, the ropes, even the harsh words aimed at her all combined to overwhelm the submissive young student. She trembled, eyes dropping down slightly, though she didn't dare look away from her reflection as she whispered "Yes..."

His lips curled back into a broad smile when she answered him. It was more than a simple answer; she was surrendering herself to her submissive masochistic nature, and to him. He turned her head towards him a bit and planted a hot kiss on her quivering, wet lips, worming his tongue into her mouth and coiling it around her's. He held the for a moment playing the tip of his tongue across the roof of her mouth and the back of her throat before breaking it with a hiss, "I'm going to give you much more soon." he told her so close she could feel his hot breath on her face, "There some special students who have been given special rights and are privvy to classified information about the school. You may even know some of them. These students are going to arrive here shortly to attend a special lecture taught by me, and you're going to be my assistant." he told her as he backed his face away.

He smeared one cum drenched finger over her blushing left cheek and licked his fingers clean before he padded her skirt down and returned it to some semblance of normalcy. He gave her plump ass a firm pat and walked behind the desk, going through the contents of the usual professor. While they may have seemed for the most part every day house hold items at first glance, a professional sadist would have recognized their other uses immediately. He concentrated my magic into making the false students and as I placed a small metal case onto the desk, the sounds of numerous approaching footsteps in the hallway could be heard.

"Ah it seems they've arrived." He said looking at Naoko with a slight smirk. The students filed in, some giving amused glances at either Ryujin or naoko or simply acting like it is any other class. "Not a single person missing, that's good. You all know what you are here for. The headmaster has requested that pass on my knowledge to you select few." he spoke as he walk to the front of the desk, "As an unnofficial educator, this class has no name. Some of you may call advanced sex ed or bondage 101 or whatever silly name you can think of. Whatever you call it I hope you will leave feeling enlightened and adventurous with yourself. Miss Naoko Lani," he explained as he patted and stroked Naoko's head like a pet "Shall be assisting me to demonstrate much of what I have planned for you."

Naoko tightly shut her dark eyes as the dragon turned her head to the side and forced her into a long kiss. She whimpered as his long, serpentine tongue slipped between her lips and twisted about inside her mouth. She shuddered, but did not dare try and break away. When the beast finally pulled away from her and removed his thick fingers from her dripping pussy she let out a slow, shuddering gasp, going slightly limp for a moment as the overwhelming stimulation suddenly abated.

She would have no opportunity to relax though; a wave of panic washed over her as she heard the giggling voice approach, shattering the silence of the otherwise abandoned floor. She wanted to hide, to duck behind the desk avoid the eyes of the students who began to file into the room as if it were any other class, but of course she couldn’t. She lost count as more and more girls poured in; how many were there, fifteen? Twenty? Even more? To make matters worse, many of them looked familiar. She couldn’t seem to specifically recall any of their names but she swore several girls from her dormitory were present, and a little knot of girls who’d eagerly taken seats in the front row seemed to be from the rival intramural soccer teams she faced every weekend.

They didn’t seem to be the least bit perturbed about the massive, muscular dragon man behind the professor’s desk, and even less so about the obviously distressed student standing before them in bondage, practically naked, her cinnamon skin glistening with a thin sheen of sweat. Her heart raced as Ryujin addressed the class, introducing themselves and explaining the course as if it were just another part of the regular curriculum.

This wasn’t happening. It couldn’t be happening. And yet her terrified mind could find no other explanation for the forty or so eager eyes watching her from the grid of desks laid out before her.

"For those of you who don't know, this is Naoko Lani. Naoko has had the distinct pleasure of my company before. And it was a pleasure for her whether she admits it or not." This got a round of amused chuckles and knowing smiles from the class, especially from the girls who knew her from soccer. "Naok has agreed to help me teach you the joys of exploring your sexuality, and to teach you how to expand on what you already know. I already know what you all are thinking; that you can learn anything I have to teach all on your own time with your own partners. What you might not learn while exploring with your partners however is safety. I'm not talking about condoms and birth control pills, but the rules and need to know facts of some of the more exotic forms. Take Miss Lani for example." he said shifting their focus onto the helpless form of Naoko.

The enormous dragonian walked around the desk and fingered the ropes binding Naoko. "This is a traditional form of Shibari, a form of bondage using a rope tied in a complicated serious of knots meant to restrain the body. While eloquent, a certain measure of care needs to be taken so that you don't cut off the circulation to the parts of the body you're restraining. Eqully important is the rope used. This is a treated hemp rope, " he said fingering the rope, " It is important to understand that different kinds of rope feel and effect the skin differently. Had this rope been left as is, Miss Lani would probably be bleeding where the ropes were binding her. But we will learn safety as we go along."

Finally the brute turned back to Naoko and smiled, "This particular configuration is a rather siple one meant to bind the hands and accentuate the breasts. Any time she tries to move her hands she will only add pressure to her chest." he said as he pinched one of her nipples. "Naoko, please tell the class how you feel in your bindings right now. Is it uncomfortable? Does it hurt? Can still feel your extremities? How do you feel about having your hands and breasts tied up? Is it different from having your hands tied from the front?" The lascivious dragon revelled in her humiliation at being forced to explain in front of strangers how it felt being absolutely powerless, and how much it was of a turn on for her.

Naoko squirmed with discomfort, writhing within her bonds. She could feel the eyes of the class on every inch of her bare flesh, caressing her body like ethereal fingers. Some looked amused, some judgmental, a few were clearly admiring her ample breasts and the helpless girl blushed brightly as a gorgeous redhead in the front row licked her lips suggestively.

As the dragon’s massive hand toyed with the ropes behind her Naoko flinched. The sudden movement inadvertently caused her to move her arms, the ropes then constricting around her succulent breasts. She hissed with pain and a few of the girls giggled, amused that she’d demonstrated the ropes’ texture quite effectively.

She cried out when Ryujin sharply pinched one of her nipples, but the illusory class could clearly hear the lust in her voice. And, of course, it got worse. She was silent for a moment, but she knew she had no choice but to answer.

“I…I can feel everything” She said, casting her dark eyes down to the tiled floor. “The ropes are rough but…but the pressure feels…g-good.”

Her usually soft, demure voice was even quieter. She could see a few girls leaning forward, but wasn’t sure if it was because they couldn’t hear her, or because they wanted a better look.

“I feel…I feel helpless,” She continued. “When your hands are tied in front of you, they…they can still protect you…hide you…”

Her chest was rising and falling spectacularly, causing the ropes to bite into her flesh ever so slightly when she took in a deep breath.

“But when they’re behind, you’re…you’re totally exposed. Helpless.”

The blush that covered Naoko's face as the fake student licked her lips at the bound Hawaiin girl didn't go unnoticed by her captor. He hadn't given any of the girls a specific task or behavior to follow, they all were simply running on auto, and he didn't intend to change that. This was a golden opportunity that he wouldn't let slip by.

"You're helpless? So there's nothing you can do to stop me or any of your fellow students from having our way with you?" he asked as he cupped her heaving left tit, rolling the firm, fleshy mound in his hand. He looked at the red head and glanced at Naoko for a second, giving her a silent "go ahead" signal.

Ryujin twisted her nipple slightly and let her luscious orb go. He reached behind her and picked up one of the items he had found in the previous professor's collection of "tools". It was a ridged, vibrating dildo that had the added ability to gyrate itself at several points, allowing it to wriggle if the user so desired. He turned on the vibration and presented it to her face before slowly running it down her body. He pressed in into each of her aroused, pink teats before moving further down. He moved it under her skirt and let it glance over her clitoris and drooling sex lips. To her horror he didn't push it into her sex, but instead continued moving south to her puckered anus.

"And there's absolutely nothing to stop me from doing this." he told her, emphasizing "this" by pushing the palstic pink sex toy into her ass and switching on the gyration function.

"Exposed... helpless..." the lascivious dragon repeated after her, "Excellent words to describe the thrill of such immobilization. Tell us Naoko, you have a bit of a masochistic streak, do you find it arousing being helpless and exposed like this? I warn you, if you try to lie, I'll know."

The redhead rose gracefully to her feet when the "professor" silently gave his consent. There was an exaggerated swing to her hips as she approached the helpless girl with a predatory grin on her face. Naoko's dark eyes darted back and forth between Ryujin and the new girl as she took up a place opposite the dragon. As the blue dragon played with her left breast the fiery-haired girl reached over and grasped her right tit.

The contrast between the beast's huge, muscular hand and the girl's soft, delicate fingers was stark. Naoko had never been taken by more than being at a time and to her horror she felt a strange new pleasure spreading through her body. When Ryujin released her breast the eager schoolgirl climbed onto the desk herself, moving behind the lovely Hawaiian so she could molest both of her lovely breasts at once.

Nao moaned as the dragon teased her body with the buzzing sex toy, her deep brown eyes following it all the way down. "Aaaaaah...!" She screamed, her entire body going tense as the thick, vibrating dildo was forced into her tight rear. Scarlett giggled and pinched the helpless girl's nipples as she writhed on the desk.

Naoko trembled, tears welling up in her eyes, as she gasped "No!"

It was obviously a lie. Copious juices dripped from the helpless girl's slick pink pussy lips, but she couldn't bring herself to admit it out loud.

"No? Then where did this puddle underneath you come from?" he asked as he lifted her skirt up for all to see. Ryujin dipped his clawed fingers into the puddle of her juices and licked a few fingers clean before passing it to the redhead as she continued fondling Naoko's ample breasts.

He reached into his vest and removed an ofuda smaller than any he had used on her before. Inscribed on the small paper charm was the japanese text for 'The Light of Truth'. He placed it on her flat stomach and activated it, the charm glowing a pale green light for a moment upon doing so. He pinched her chin between his fingers, forcing her to look at him, "I don't think I believe you Naoko. I'll you what, if you tell the truth this time, I'll take a bit of the vibrator out, but if you lie I'll leave it in and do something even worse.Now tell the truth; does being bound and exposed arouse you?" he asked her.

The helpless girl whimpered pitifully as Ryujin lifted her skirt, exposing both her smooth, glittering pussy lips and the impressive pool of honey beneath them to the illusory class. The girls all leaned in, eager to get a better look at Naoko's impressive state. Many of them even scribbled down notes and made quick drawings of her state in their notebooks. The Hawaiian girl's deep, dark eyes followed the beast's fingers as they dipped into the pool beneath her dripping sex and rose up to his mouth. When his tongue snaked out to taste her sweet juices the bound girl involuntarily shuddered, remembered what it had felt like to have that tongue wriggling inside of her tight little cunt.

The red haired girl leaned over and eagerly sucked the remaining juices from the dragon's thick, scaled fingers. All the while her skillful hands massaged the caramel-skinned beauty's magnificent breasts, ensuring that the poor girl would be given no respite from her lust. "Mmmmmm, absolutely delicious..." she hissed, leaning forward so her lips brushed the edge of Naoko's ear as she spoke.

The helplessly bound girl whimpered when the small strip of paper was placed on her naked flesh. She obviously couldn't read the words written upon it but nothing good had ever happened when those accursed slips had been used against her in the past.

Self loathing welled up within her, but she had no choice. The helpless girl had no doubt that his words were true and a cold terror coursed through her veins as she wondered just what tortures he would inflict upon her helpless body if she lied.

"Y-yes..." she whispered. Though her voice was soft it almost seemed to echo in the otherwise silent classroom. That was all she was required to say, but still the words continued to spill out. Even the humiliation of being forced to tell her deepest, darkest secret to a group of total strangers caused a wave of lust wash through her already aroused body.

"You can do anything you want to me. They can do anything they want to me." She continued. Both her body and her voice trembled noticeably as she confessed. Countless scenes flashed through the seemingly innocent young girls' mind; visions of Ryujin fucking her every way imaginable, visions of the entire class taking turns molesting her helpless body the way the red haired girl was right now. They could taste every inch of her flesh, or force her to orally pleasure each of them in turn as the dragon's massive cock raped her tight little pussy.

"I'm helpless to resist. I'm just...just a fuck toy for you." She said, her heart beating a mile a minute beneath her heaving breasts. "You don't even have to keep your promise. There's...no way for me to resist."

And somewhere, deep in the darkest recesses of her mind, she hoped he would break his word and subject her to whatever horrible fate he had concocted.

Ryujin was completely taken aback by Naoko's answer. He never expected her to break so completely and utterly that not only did she tell the truth, but she let out her her deepest, darkest secret to an entire classroom of strangers. She was practically begging for him to freely use her young body for his every pleasure. "God," he thought, "She's one in a million. You could look the world over and never find a jewel like her." he thought to himself in appreciation of her submissive nature. "The boy who rejected her was a fool. He cold have molded her into the perfect sex toy, but instead he threw her away like garbage. She deserves better." he thought to himself. Ryujin may not have respected Naoko as an equal or even cared about her, but he valued her as a jeweler values a precious gem.

Ryujin ran his clawed hand over her silky, raven black hair, "Good girl Naoko." he said as he continued to pet her like an animal, "Class I want you to take a good look at Miss Lani. What you see here is a true masochist. 'I'm helpless to resist, you don't even have to keep your promise' she said. To be bound, naked and exposed; to be lowered, almost to an object, to feel the full shame and humiliation of being seen for what you really are at your core. To be helpless. To want to be helpless. At the mercy of someone you trust fully. To be and do all those things and take pleasure in them, that is the epitome of what it means to be a masochist. Some of you may be intrigued, some of you will never understand and some of you will never want to understand. But now you know that a person can sink to lowest depths of society and be in utter contentmentt and bliss."

Ryujin turned back to Naoko and ran his left hand down between the valley of her breasts, over her flat tummy, under the waistband of her skirt and slipped his fingers into her slick cunt once again, "And you really do love this feeling don't you Naoko?" he whispered to her and began pumping his fingers in and out of her squishy snatch audibly. With his other hand he took one cherry pink nipple and pinched and twisted it cruelly, but not enough to make her cry out. He leaned in and whispered a promise to her, "I want to fuck you so much Naoko, but I won't. Not yet. I'll let you suffer much more before I do." he whispered and let go of her abused nipple.

He motioned for the redhead to back away from Naoko. He picked her up and spun her around so that she faced away from the class. "Naoko, bend over and stick your ass out." He instructed her. When she did so, he hiked up what little of her skirt covered her ass and drooling cunt and gripped the vibrating, gyrating dildo and churned it around inside her ass for a minute before slowly pulling it out. He handed it to the redhead who gleefully gave the pink sex toy a long lick along it's length. "We will now be demonstrating a few alternatives to any average sex toy you might carry with you. Take these for instance," he said picking up a long line of anal beads that were about half the size of golf balls, "These anal beads create a different kind of feeling from a dildo. You insert them one at a time like so, " he said pushing one, then another into Naoko's abused rectum, licking a sliver of drool from his lips as he did so.
