Among those students who fell prey to Shokushu's monsters, detentions in the dungeon-like basements were infamous. But not all detentions led immediatly to monster assault. For every girl who was raped in those dungeons, a dozen more served their time in a classroom with an actual teacher and left praising their good luck. It was all a matter of where you were assigned.

Steel didn't feel like leaving things to luck. Every so often when he was having trouble finding prey, he would sneak into the offices and look through the detention slips that were going out the next day. If he found a student that looked tasty, he'd change the slip and have her sent straight to him.

This particular night Steel found a very interesting girl. "Karen Hinase, caught with a bokken carved from a tree branch." he read aloud. "Huh, pretty resourceful." He looked her up in the student records, and the picture attached- damn, that girl had some nice curves. Alright! A quick cantrip cast on the slip of paper changed the room assignment from "Main Class Building 2-A" to "Basement Level 3 Room 11." The next day Karen would be given the slip by a teacher, so all Steel had to do is wait for her after classes let out. He could hardly wait.

step. step. step. Karen came down into the basement slowly, each step sounding ominous to her ears. They echoed off the walls, and her fingers that gently slid along one wall of the stairs searched incessantly for a light switch.

Karen had her practice-weapon taken, a frustration that bothered her to no end. When she first got the slip and complaint, she could hardly believe it! How could anyone run something like a kendo club here?? She decided then she'd plead her case at the detention; if she was going to start such a club, they'd obviously need equipment. And student clubs were certainly allowed!

But a deeply worrying feeling built up when she found the location of her detention. /What the hell? That's... strange./ Not having ever been in the basement before, nor even having had a detention before, she had to ask another student where she'd go to find it. The girls' reaction, one of mild horror and pity, worried her even more. This was an institution, right? She had seen a few odd things here... but was there something even more under the surface?

Karen knew that she had to find out. And so when she descended, it was with steel in her back and a tremble in her soul. Breathing in deeply, her breasts rising under her school uniform, she paused and closed her eyes. Taking a few moments, she began to walk back down again, slow and steady.

"Hello...? Is anyone down here?" She asked aloud, her other hand closing into a fist as she fought to keep the tension from her voice.

Silence was the only answer. When Karen got up the nerve to walk all the way down to the 11th room, she would see a note on the door. It read simply "Miss Hinase: Please have a seat inside. Your detention officer will be along shortly." Real dedication these people had huh? Couldn't even be on time to the detentions they set.

The room was surprisingly clean considering how dank the hallway got in places. There was a desk with a stack of papers on it and a chair in front of the desk. It was a strange chair though.... Black leather, much better padded than the wooden chairs in the classrooms. It looked like it could recline too. Having to sit in this comfortable looking chair certainly wouldn't be punishment! But there were some odd pieces of metal on the back of the headrest, on the opposite side from where a person's head would be, and on the sides of the footrest too. They looked almost like... shackles.

Karen peered around, walking slowly. Finding the door, she snorted and rolled her eyes. God! She almost turned around right there! But she was trying to be a 'good student'. It was important to uphold rules, after all... sighing softly, she pushed her way inside.

At least the room wasn't as bad as much of the hall. Maybe they were serious about this business. She folded the letter in her fingers thoughtfully as she eyed the papers. No one was here... strange. And the chair...?

Oh... funny. Very funny. I'm laughing. And I'm not sitting on THAT. She said to herself, walking up and sitting on the edge of the desk. She tried, at least, to fold her arms in her lap and look... somewhat formal. Waiting and curiosity got the best of her, though, and she began to lean over and leaf through the piles of paper as she waited for her... "parole officer" to get here. Brushing back her dark hair behind one ear, she began to idly read.

The papers weren't anything interesting really. Standard detention busy work. It didn't seem quite appropriate though. Some of it was old, old work and some was material she hadn't yet covered. Like whoever left them for her just grabbed whatever was handy.

As it turns out, that was exactly what Steel had done. The papers were meant only as a distraction for her. All the time she was there, Steel was watching, using his demon powers to hide himself in the shadows around her. And now, with her attention on the papers and her guard down, he was ready to strike.

The leather black tentacles were silent as they burst out of the shadowy wall behind Karen. Her only warning would be when they touched her skin, wrapping around her wrists and waist with a grip like steel (fittingly.) Steel laughed low in his throat but didn't emerge completely yet. He always liked to pause for a moment to see girls reactions when they were first grabbed, before they knew who and what had them. Some shrieked, some growled, some fought.... He had this Karen pegged for a fighter, no question.

Karen had been expecting something... someone to come in. Some sort of trouble. She didn't expect something to come from the freaking wall!

SH- LEGGO YOU BASTARD! She turned her head, one full breast brushing against the tentacle around a wrist as she -seized- the stack of papers, flipping them back behind her as she tried to drop backwards and to the side in a roll!

It was pure desperation, flinging something into his face and doing a roll... the only direction the tentacles may have trouble holding her in. But she could just as easily end up seated and pinned against the wall if she did it wrong... or the tentacles were strong enough to pull her even in mid-roll.

Whether she rolled up to her feet or was pinned, her breasts rose and fell as she breathed in a panic, eyes wide as she tried to maneuver away... it had been a long time since she ran into a monster, and this one was MUCH different than what she ran into before!

Karen's reaction time was even better than Steel had predicted. She barely pulled herself away from his tentacles' grasp, hurling the stack of papers at them and hurling herself in another direction. Surprisingly, a hiss of pain came from the direction of the wall, and the tentacles pulled into the darkness again. She had managed to hit him!

Or so it seemed. The demon was actually toying with Karen, pretending to be hurt when in reality he had barely been distracted. In the instant that his tentacles vanished, he darted around the room, leaping from shadow to shadow until he landed in the shadow Karen's body made on the floor, blocking out the dim light from a light bulb hanging on the ceiling. The tentacles lashed out again, this time all ten of them coming at her from multiple directions and once again aiming to catch her by the wrists and the ankles.

NO! She cried, darting away! Karen's only hope was to buy enough time to get at the door... she ran, diving UNDER the desk. It was a simple trick, trying to funnel them under. As she came out from the desk on the other side, she KICKED the side, toppling it on the tentacles pursing her!

But as she sprung back to her feet, hair dancing and breasts bouncing, she still found herself seized from behind; trying to pin them only stopped those following her from behind, and there was plenty others coming at her when she turned to kick the desk. Now she struggled and fought, gasping, kicking, wide-eyed and panicked.

No! Where WAS this thing, how did it attack like this?? It defied all practical reason, even more so than normal, and she breathed in deeply as she struggled to calm down, making her ample assets rise and fall, and her long limbs to quiver in fear...

Once one of the tentacles finally got a firm grip on Karen's wrist, it was all over. The demon's strength was more than a human could stand against, even one as strong as Karen. It pulled her down to the ground slowly but surely, while the other tentacles finally managed to catch her other wrist and her ankles. She fought him every step of the way, struggling and bucking in his grasp. But Steel finally had her, held with her back against the floor as if shackled there, wrists next to her head and legs slightly apart.

Karen started breathing deeply and trying to calm herself- but Steel's next action wouldn't help her with that. A rough masculine hand suddenly groped her shapely rear, tugging her skirt up and squeezing one buttock roughly. The other hand was next to emerge from the shadow, and it reached up to paw at her heaving breasts through the uniform top. Pale clawed fingers rubbed slowly and forcefully, especially over that area where her nipples were hidden by clothing. And all the while Karen could hear that low dark laugh from before....

NOOOOO!! Karen screamed, pulling desperately at the tentacles that held her as strong as steel and the rough hand felt along the curve of her ass. Her composure broke, and she snarled and struggled frantically! It was to no avail; her breasts bouncing and body heaving as she fought, then trembled as her swaying breasts were pawed roughly.

The fight left her swiftly and she hung limply in the tentacles... Karen quickly realized that fighting was just going to leave her too tired to escape. The laugh drew a sensual shiver down her spine, felt through the shape of her firm ass, and Karen realized her nipple was reflexively hardening at the rough touch of the clawed fingers. Trying to slow her breathing, her wide eyes still spoke of fear, and her black hair spilled and shifted across her shoulders as she looked quickly for something, anything, to escape with...

Once Karen had stopped struggling in his grasp, Steel squeezed her breast roughly one more time before removing both hands from her. His tentacles lifted the girl up from the ground, shifting her to a vertical position again with legs still held wide open and hands now bound together above her head. And as she hung there suspended, Steel finally rose from the shadow on the ground, revealing his full demonic body to her if she chose to look behind her. "That's more like it" he laughed. "Ready for your punishment, Miss Hinase?"

Steel stepped up behind her, his tentacles holding her in place. He pressed his body up against her from behind so she could feel his muscular chest against her back and his growing cock between her ass cheeks. He reached around her again to cup both of her heavy breasts in his hands, groping and pinching like before. But after only a few seconds of this he raised the stakes, grabbing her uniform blouse and yanking it open, buttons flying across the room. Her bra was even unluckier, torn in half and dropped to the concrete floor. Now with Karen's breasts bared to the cold basement air, the demon could really play with them, paying special attention to her hardening nipples. He pinched and rolled them between his fingers mercilessly....

Karen grunted as her breast was fondled one last time, firm flesh pressing against his hand. Her arms pulled a little as she was hoisted, wrists held together in a pose of submission, and her legs spread lewdly like she was some common slut. It made her breath harder, the warrior-girl insulted and angered, but fear flooding her veins as she realized how much trouble she was in.

Hearing the voice now behind her, she tried to turn her head, peeking over her shoulder as the muscular demon pressed in close. Feeling his firm muscles press against her back, her breasts rose and fell faster, a cry escaping her lips as she felt something hot and hard pressing between her buttocks.

Oh god... seriously, don-AOH!! Karen's breath was stolen as her large mounds were seized anew, fleshy orbs quivering as he began to grope and pinch the roughly. Only the uniform and bra protected her... and those protections were torn aside like paper! Karen winced at the sound of buttons clacking against the floor and wall, her eyes catching sight of her white bra toppling away in two pieces.

With the chill of the basement sinking into her skin, it wasn't the cold alone that made her peaks hard to the touch. A low, surprised moan escaped her lips almost like a hiccup, and Karen pulled herself to the left and right, trying to dislodge those devillish fingers!

But it was hopeless; ample tits rubbed against his fingers, quivering as her poor nubs, growing harder with each passing second, were ruthlessly played with. She had to do something! But she knew it was impossible... Karen's breath caught in her throat, but she wasn't able to hold back a second groan for long...

Steel snickered as his attentions to Karen's large breasts drew unwilling moans from her throat. He growled lustily into her ear as she squirmed and fought, managing only to rub her buttocks against his thick member. In turn he bucked his own hips, grinding against her to demonstrate what she would have inside her before long. His mouth found her ear and neck, and he nipped, sucked and licked at the bared skin she was forced to offer him.

Soon a hand left those lovely mounds, and roamed down her tummy to her skirt, while he tugged at her nipples with the hand that stayed up top. Her skirt was tugged up in front and tucked into the waistband, leaving her panties on display to the room at large. Steel traced the contours of Karen's pussy through the panties. But the impatient demon took only a moment to tire of that. He hooked his fingers into the panties and yanked hard, tearing them away with no more effort than it took him to destroy her bra. The girl's sex was now bare to the cold air in the room- and to Steel's fingers, which began to alternately rub her clit and stroke inbetween her lower lips, just an inch or two. For now.

N-nyahhh! Karen's gasp was an amusing sound, shock, shame, and pleasure coloring her out cry. She tried to shout, to scream, but she had cut herself off with a shocked cry, caused by the sensation of lips on her ear and neck. Feeling the pulsing member rub against each curve of soft cheek, Karen bit her lip and whimpered. Oh god, he felt so... masculine. Not just a demon, but a ripped, hungry, animal of a man, teasing and toying with her body like it was his to own.

Breasts heaving as she panted, she struggled to wriggle her waist, trying to evade the fingers that slid down her flat stomach and teased across her sex. She flinched as her guarding barrier was torn away, her sex becoming slicker as she began to come closer to a complete panic. She couldn't stop the moan of pleasure and fear from escaping her as his fingers pushed into her puffy lips, exploring, stroking, teasing her. Telling Karen that he could make her feel pleasure just as he wanted, to toy with her body and access anywhere he wanted on her... she finally managed to growl, but her snarls would waver as her impressive mound pressed into his palm and her lips clung to his tracing fingers.

WH-WHY? What... ARE you?? She asked, desperate for something, anything to slow this creature down... or to take it's mind elsewhere.

Steel's fingers played and teased with Karen's body like a prodigy would play the keys of a piano. He couldn't get enough of those massive breasts, and he couldn't wait until round two when he'd have a chance to get his mouth on them. But no reason to get ahead of himself. His fingers curled inside her slick sex and seeked out the most sensitive places deep inside her. No matter how much she tried to struggle away, her hips were pinned between his hand and his cock, and pulling away from one only pushed her into the other.

Steel hummed happily as he explored his captive's body. "Well well, you're wetter than I thought you'd be. You're really getting into this, hm? You might even be ready for the main course already! Don't worry, I won't make you wait long." One of his free tentacles hooked his black pants and tugged them down, allowing the thick cock Karen had felt through them to spring free. He shifted his hips, and his member slipped between her legs and rubbed against her lips. Back and forth, not penetrating her but clearly preparing to. His fingers inside her began to spread her open....

At Karen's desperate outcry, there was a brief pause. "Oh, I've been rude, haven't I?" the demon chortled. "Here I am already knowing your name, records and why you're down here.... Very well. I'm a shadow demon by the name of Steel. I was summoned from Hell about 850 years ago by a cute little witch girl who wanted a servant." Another nip at her earlobe and pinch at her clit before he adds in a whisper "I made her mine instead. And now it's your turn. Ready?"
