Ryu felt her bare back being revealed after the uniform had been cut away after all, lying on the ground as she heard the steps of her teacher moving backwards again as she seemed to walk in the direction of the closet, obviously searching for the perfect method to punish the young girl in her defenseless situation.

Why the sudden change of your mind? Did you ever punish a student before? You don't seem like a person who could do such a thing.

The teacher exclaimed with glee before approaching the student again, a sudden, significant pain entering the redhead'd back as the teacher used her tool of penalization. She grit her teeth to avoid to scream by the surprise, avoiding to reveal any sign of the pain affecting the student. Ryu wouldn't expose herself that easily again. The pain faded away, obviously the teacher just wanted to try her new toy, watching the result carefully of course like someone in her situation would. The student shivered lightly, still feeling something by her slit, raising her head after the shock a little further.

Everything you got Krystan? It's amazing how you let yourself go after all, still I don't think you could break me down here in the basement...

As the prod touched Ryu's back Ms. Krystan couldn't help but giggle. She tapped it against Ryu's back a few more times, giggling at each tap, before she held it against her lower back just above where her cheeks started to split apart.

Seraph sighed to himself at the teachers behaviour. That was the problem with using magic to control someone, well when combined with its duration. They started to rely on it, and as more and more magic was used to control them their mind faded away into blankness. Looking up Seraph realised that Krystan had been holding the prod in place for 3 seconds. At a mental impulse she suddenly dropped the prod and went back to rummaging through the supply of devices.

Ms. Krystan exclaimed with glee yet again as she found her next toys to try. Of course this would require the assistance of the knife again. Recovering the knife in one hand she starts walking until she stands in front of Ryu and starts to cut away the front part of her uniform. With Ryu's limbs still trapped in the chair she could do nothing to stop it, and when she tried to protest Ms. Kyrstan's free hand slapped across her breasts.

The student couldn't resist the pain anymore, screaming horrified every time the prod touched her skin and spreading the shock through her body. It was embarassing for her to hear the almost mad giggles of Ms. Krystan, some kind of revealing her true intentions about the detention she decided to pass Ryu.

Ms. Krystan obviously decided to punish her with conviction, helding the prod agaist her lower back for some seconds, Ryu's mouth opened as she wanted to scream but forced herself to get control on her shivering body again as the teacher suddenly dropped the prod and made her way back to her arsenal. Her head dropping in her neck to face the ceiling she felt how her eyes turned into a wet state, obviously the girl was about to cry in her rage and increasing anger. Still, her weakened body forced herself to smile with her following words.

You know what Krystan? I underestimated you, I never thought you'd be such a sloppy person.

The teacher made its way back to the bound girl, starting to cut away the front of her uniform. She wanted to get rid off the chair, but the steel was too strong to break it, as she was about to speak Ms. Krystan slapped across her breasts. Ryu growled angrily as she found herself being helpless in a chair, in front of a teacher who'd punish her without a doubt.

Ms. Krystan, who by now couldn't hear anything except the voice inside her head guiding her, hummed as she cut away the front of Ryu's uniform. As she cut more her eyes seemed to blank out, yet her body cut faster and more confidently.

Soon the front of Ryu's uniform fell the the floor, revealing her bra. Although as Ms. Krystan tutted at the sight of it Ryu would be able to guess it wouldn't remain for long. However rather than use the knife Ms. Krystan walked around behind Ryu and she first grabs the next device to use on Ryu that she had found earlier before she unclipped Ryu's bra. Pulling it down off her breasts Ms. Krystan reaches around Ryu and squeezes each breast in turn before clamping a metal clamp attached to a slight weight via a chain to each nipple.

Once they are in place she walks back around to the front of Ryu and taps one, and as it jiggles around she bursts into another giggle and she repeats the motion.

The metal clamp forced to student to wince as they got attached to each nipple, gasping once as the pain and pleasure spread through her chest, her exposed front stood out as she tried to straighten her bound body again. The weight on attached to the clamp made it harder to resist the feelings it created without the teacher's help, but was enough to unnerve the student for a short amount of time.

Ms. Krystan appeared in front of Ryu again, teasing her nipples and stimulating her senses as she taps one of the clamps, bursting into another evil giggle before repeating the motion. Ryu blushed heavily as her mind registered the sensations running through her cores as the teacher started to enjoy the full control of her subordinate student.

S-stop that Krystan, you filthy-... Clear off, damn it!

Obviously her words wouldn't affect the teacher due her happiness about Ryu's detention, finally revealing her true intentions about her personality. The quite attractive female seemed to have other things in mind, Ryu started wondering what the woman was about to do next. She'd better start to enjoy her punishment or this was going to be a long day.

Ms. Krystan can no control herself, she is mesmerised by Ryu's breast as it gets pulled around by the weight, giggling each time she taps it.

Seraph however quickly grows bored of Ryu's reaction, and at a mental command Ms. Krystan suddenly loses all interest in tapping the weights and walks back to the pile of items.

She rummages around for nearly a minute before finally exclaiming with glee. She has found the next toy to try.

The disability of not being able to to turn around made a cold shiver appear, running down Ryu's spine as she heard how the teacher searched for another tool she'd tease the student with. Of course it'd be harder to win this time, but after all it was just Ms. Krystan, she just won't be able to do something like that. Perhaps I am wrong...

Ms. Krystan's glee appeared to be a sign if she made a discovery about what she had in mind, she'd use the tool she found for her entertainment of course. The girl bobbed up and down in her chair, the weights lightly pulled down her nipples which made it pleasant and uncomfortable the same time.

Hey, what are you doing?

I know a secret Ryu. A dirty dark little secret of yours. Krystan's voice whispers in Ryu's ear and her breath blows across her neck. That is such a beautiful flower in your hair. Krystan's free hand strokes Ryu's hair and briefly touches the flower entwined in it. Lirila.

At Krystan's word the dormant hypersensitivity spell inside the flower activates, and Krystan quickly uses her free hand to tap both of the weights clamped to Ryu's nipples in turn. Now isn't this much better?

With that Krystan nibbles slightly on Ryu's ear briefly before her mouth moves down and starts to kiss Ryu's neck.

In the other side of the room Seraph smiles at Ryu's reaction, he wonders if she has finally started to realise that she is not just dealing with Ms. Krystan, and if she has if she has managed to work out he is the one behind it. The only real clue she had was the activation of the flower, but her mind might not have been able to make the connection.

After the teacher said the name of the flower, activating its effect before tapping both of the weights clamped to her nipples. The feeling as she nibbled on her ear before kissing her neck was stronger than usual, she found herself enjoying the harsh treatment of her teacher, but after all she didn't reveal much but a silent gulp to remove the knot which stucked in her throat.

How did you... know about that?

The fact she knew the name could mean two things, either she followed the student and watched how she got more or less voluntarily raped by the angel, or the misterious male was playing with her right now. Skills were a big advantage the monsters from the island had, she was just a regular student like anyone else, well not that regular after all. Still, the latter seemed to be rather possible than the first one, Ryu was just not used to the angel at all, she knew almost nothing about his skills.

Her eyes flickered around, searching for a sign of his appearance while she tried to keep any kind of pleasure inside her body, the girl wouldn't reveal something about her that easily.

At Ryu's words Ms. Krystan stepped back from Ryu and she stands silently behind her, letting the anticipation of her next move build in her helpless victim.

Suddenly Ryu's vision goes black as a silk blindfold is brought over her eyes. With the blindfold in place Krystan begins her assault on Ryu's helpless body anew. Hands rub across her back and around her neck before sliding down her body and gently caressing exposed breasts. Every movement Ryu makes causes the weights attached to her nipples to pull them, but with the hyper sensitivity spell contained in the flower active she struggles to remain still. And the more she moves the harder it becomes to remain motionless.

Suddenly Krystan pulls back, and she turns and walks to the pile of tools. Selecting a whip made up of a dozen strands of very thin silk she walks back and runs the tips lightly across Ryu's back a couple of times before pulling it back. Hesitating, again to build anticipation, she lets Ryu sit for several seconds before the silk whip is brought lightly across Ryu's back.

As her vision goes black Ryu found herself going through a small amount of fear as the seconds passed them by, suddenly interrupted as she felt her teacher's hands experiencing the flesh of the helpless student. Harldy able to resist her touch her body shivered lightly, the weights on her nipples swaying nimbly as she did, giving her more material to feed her lust as it slowly began to build up inside her body and mind.

You damn bitch, what are you doing? Talk to me!

Ms. Krystan stopped her movements, hearing her steps was quite awkward due it seemed to be some kind of pattern, she walked to the tools, grabbed one and returned. Simple, but effective like nothing else she could use. She winced slightly as something touched her back softly for a second, it felt like a whip, but Ms. Krystan wouldn't do something. On the other hand, she did something to her already.

Seconds passed, anticipation building up inside the student as she waited for the next thing to happen, suddenly feeling the harsh touch of the whip again. Ryu gasped as it did, the pain which actually got transformed into pleasure while staying in her mind spreading through her wincing body again, receiving pleasure by the weights on her nipples as she moved.

Your a very naughty girl, aren't you Ryu? As Krystan speaks she lashes out with the whip again. Tell me about the prettiest student you fucked. Don't try to deny it, I know you have. And until you do I am going to keep doing this... As she trails off Krystan whips Ryu's back again.

Drawing the whip back for another strike he freezes, and lets the seconds drag on before whipping Ryu's soft back again. She repeats the movement, always letting a different amount of time pass between strikes. Never giving Ryu any warning, sometimes the strikes come straight after each other, sometimes several seconds pass between them.

As he watches Seraph decides to increase the strength of the 'attack' on Ryu's helpless body. The chair under her fold gains a ridge that rubs against her pussy through her panties. Every time her hips move it grinds her pussy against the new ridge, and every time the whip strikes her back she cannot help but squirm.

Ms. Krystan teased the redhead over and over again, whipping her back every now and then which gave Ryu a feeling about what she had in mind before she even arrived to her detention. The defenseless girl winced every time the teacher hit her back, gritting her teeth due the pain entering her already desecrated body over and over again.

Why should I tell you? Whatever you say or do, you have to be pretty stubbornly to get one word out of-

Another strike of the whip stopped her talking, again the poor student winced as it hit her, but something seemed different. Something rubbed against her pussy as she did, so the girl squirmed which just increased the effect of the unknown thing. Finally stopping, another strike made her hips move forward, forcing the girl to feel the ridge every now and then as the whip hit her, her own attempt to struggle herself free drove her almost mad.

Ryu gasped again as the whip hit her, it wouldn't take much longer to force her to speak like the teacher wanted her to, even though it was the most embarassing thing she could do.

As Ryu gasps Krystan lets out a small giggle. The gap between strikes becomes the longest yet, but the follow up strike hits the moment Ryu manages to stop moving her hips. Krystan doesn't know about the ridge in the chair, she is simply listening to the voice in her head for when to strike.

Seraph can see Ryu's resistance breaking, if it was just the whip than she could probably hold out longer. But it isn't. The flower, the ridge, and the clamps on her nipples all play a part in shattering her mind. In fact, speaking of the clamps on her nipples... Seraph focuses on the magic that created them, and suddenly instead of simply clamping down they start to suck on the flesh they are clamped around, drawing her nipples out into them as the weights continue to pull her breasts down. He watches as before Ryu gets a chance to get used to this new stimulation another strike from the whip grinds her pussy against the chair. It won't be long now.

Ryu suddenly noticed how the metal clamps started to suck on her nipples instead of just clamping down on them. Her nipples hardened abruptly, growing in size as they stood out significantly, the weights attached to the clamps made the whole situation worse equally like being treatened like a piece of flesh as getting stimulated by the attractive teacher behind her.

The girl moaned significantly as the weights pulled down her nipples and the misterious ridge pressed against her pussy as the whip hit her again. The sudden hits surprised her so she couldn't resist moving her hips forward, receiving the pleasure of utensils attached to her like the sensations she felt as her body dumped against the ridge every now and then. Ryu writhed in the chair's grip, it just filled her up with more lust and pleasure, her resistance and self-confidence would be broken if she kept resisting.

Allright, allright, stop it! I will tell you...

She knew her resistance was futile, her climax would come closer and just reveal a side of her she disliked for some reason, of course not if the other side of her personality would be able to take over the control of her body.
