"Ahhh.. not so.. hard.. *gasp* It's.. ahh.. too tight!", Pia moaned.

Despite Ms.Saika's lecture, Pia had of course tried to protect herself, but had been helpless against the onslaught of the tentacles. They were too fast and too many, and Pia already knew there was little point in fighting, her initial struggles mostly a result of instincts kicking in before Pia could calm herself.

With a few swift movement, Pia was pinned and placed in position for Natsuki's tender ministrations. Soon Pia was placed face and palms against the wall, her round rear pushed up and out towards the teacher, Pia gasping for air as Natsuki was lacing up what appeared to be some sort of corset. Despite Pia's protests, the garment did fit. It fit perfectly, in fact, Natsuki again displaying the phenomenal skill she had displayed in creating the doll Pia had destroyed earlier. It was tight, certainly tighter than what Pia was used to, but not overly much so, and it perfectly encased Pia's body, enhancing her hourglass figure.

Apparently, the result pleased the tentacled lady, as she admired the combined effect of Pia's position and the corset. A less patient monster would probably have just taken a firm grip on Pia's inviting, round ass and then mounted her from behind right there, but so far, Natsuki seemed content to just let a few of her tentacles slide across the student's soft skin. Pia trembled, finding the touch both terrifying and oddly sensual.

The corset was not the only thing Ms. Saika had prepared, though. But it was only when she handed over what seemed to be the last piece that Pia understood where she was going with it all. "Uh.. really?", Pia said, accepting the headband and, seeing no point in protesting, putting it on her head.

Natsuki had clearly had the iconic playboy-bunny in mind when designing the outfit, but by no means felt obliged to merely copy the original design. Overall, the outfit was dominated by soft, pale pastels, powder pink and white, combining with Pia's blonde hair and blue eyes to create a sense of girlish, innocent cuteness, somewhat at contrast to the fetishized design and intent.
The main piece of the outfit was obviously the corset, which tightened Pia's waist and supported (but barely covered) her breasts. It was made in the soft color palette that dominated the outfit, with pink in the fore and tiny details in golden canary, and adorned with lacy trimmings.

Pia was also wearing white fishnet stockings that went up to somewhere above mid-thigh, matching lacy gloves, and a choker. Fluffy bunny ears topped off the outfit. Pia was not allowed panties, leaving Pia to try to find a position where she could shield her exposed ass and pussy as well as she could.

Oddly, the outfit did not come with a tail, but then there was little to fasten it to. The traditional pumps were also missing, which gave Pia a chance, should the unlikely opportunity to run for it present itself.

The boots were pink, front laced, and of a height to go just above the ankles. Design wise, they were actually kind of cute, if they had not been so obviously made for fetishism. The heels were thin, and tall. To walk in them seemed an impossibility. Pia guessed that was the intent of the creators. It made sense as a sort of kinky game. She could even imagine it would be fun in different circumstances. Completely dependent on her partner, relying on her for aid, completely helpless should she decide to take advantage of the situation. Doing something like that with Susan would be fun.

In a situation you hoped to escape, on the other hand? Not so much..

Despite some protests and squirming from Pia, It was easy enough to get the boots on her feet. It was just a matter of keeping Pia in her disadvantageous, forward leaning position and using the advantage of tentacles. Should Natsuki become impatient, Pia's round buttocks were in a ripe position for a few smacks of a palm or tentacle, enough to persuade the distressed damsel to cooperate.

The boots encapsulated Pia's dainty feet even more firmly that the tighlaced corset. The material was hard and stiff, necessary to support her feet in such an unnatural position. Pia's feet were completely straight out, making the curves of her leg muscles stand out (despite preferring flats or very moderate heels, Pia had the legs for higher heels. She would probably look smashing with pumps and a retro style pencil skirt).

The corset and the boots joined forces to make Pia feel incredibly constrained, yet there was something almost intimate in the way her garments fit her, chosen to both restrain and enhance her figure, forcing her to suddenly re-evaluate such things as how she breathed and stood.

Standing was indeed a challenge. She was literally at her tiptoes, unfamiliar pangs of pain going through toes unfamiliar with the pressure of her weight. The contact surface with the floor was minimal, putting hard demands on Pia's balance and legs. She yelped helplessly, almost falling over, in the end only remaining standing because her upper chest and palms were pressed against the wall.

This made her butt the perfect target for..

"AHH! What.. are you doing! Please.. not there, not my A-AH!" Pia's anal opening resisted the invasion of the buttplug at first, aided by her clenched buttocks. Some prodding and poking was necessary, but once the plug began to slide in, it fit perfectly, snug in her tight asshole. Pia's reactions revealed that her lower body musculature was pretty strong, but also that her body knew how to accept an intimate intrusion from behind. Indeed, a few monsters had already discovered just what a source of pleasure Pia's ass could be, and though she would never admit it, not every recollection that flashed through her mind was unpleasant.

The plug itself was just big enough, any bigger and it would have been painful. It felt like it had some sort of tiny nubs on it, teasing her sensitve opening as they went in. In contrast, the tail was soft and fluffy against her skin.

Every time Natuski slapped Pia's rear, Pia rewarded her with a cute little yelp, and with a wiggling ass as she instinctively recoiled from the impact. Not that it hurt, not really. This was well inside Pia's limits. Hat it been someone else, like Susan or Kanoe, Pia would likely have been begging for a harder slap by now. Once again Pia realized how close this was to something she might enjoy, or even have fantasized about.
The reminder, if not enough to make Pia aroused as such, at least added an element of.. excitement, for a lack of a better term. It was not just fear that caused her adrenaline to spike and her senses to become more keen and aware. Perhaps her nature as a vuluptarious added to this as well. She was instinctively keyed towards pleasure, reacting to the pleasure of those around her. Natuski and Pia had shared a very intimate moment earlier, and to Natuski, this was her chance to fulfill any fantasy she had involving Pia. Pia could almost feel it, a cold flame of controlled, calculated desire.

What did hurt, however, was Pia's legs. They were stuck in a most unnatural position, and Pia did not know anything about how to wear such footwear. Balance was an issue, causing Pia to expend needless amount of muscle power just to find how to place her weight. Right now, the wall and some manhandling by Natsuki's tentacles were the only thing keeping Pia standing.

Despite protest, Ms. Saika seemed adamant that she stand upright. Quite frankly, Pia thought it would be easier to take a butt plug, or a tentacle for that matter, than to stand, but she was not given any choice in the matter. Pia had no choice but to yield.

The result was less than elegant. Just getting into an upright position was a challenge in itself. In the end, Pia leaned forward as much as she could, and then pushed herself away form the wall. As can be expected, that did not work out so well, and just a quick tentacle prevented Pia from falling backwards. Now in upright postion, it looked like she had found her balance. Her back was straight, her legs straight, poise upright, chest forward.

That lasted for almost 6 seconds. Then Pia's legs began to slowly glide apart, slowly parting. Pia panicked, but she just did not know how to stop the slide. Panicking, she tried to shift her feet, flailing her arms for balance. It almost worked. Pia let out a sigh of relief, her bosom visibly heaving over the tight corset. But now her feet began to slide again. Pia scrambed for support, ending up with feet crossed.

Pia flailed in panic, tilting back and forth.

Pia was hanging from her arms. The postion made it feel like her breast were now above the corset. Pia glanced down. It was hard to tell with the trimmings, but it appeared that her nipples might be peeking out. Pia's first insinct were to try to place her hands over them, causing her to struggle against the tentacles trapping her arms. This was not a wise move, at least if modesty was a priority. Now Pia was sure at least one breast peeked coyly from it's sexy trap.

Pia neededto calm down. She forced herself to breathe deeply. Much as she loathed to admit it, Natuski had a point. Right now, she was just presenting herself as helpless bait.

"Err.. beravishment.. I did not know that was a word..", she said, buying her time to think and calm herself. She tried to test the ground a little, trying to find a position for her feet that would keep her a little more stable.

"..uhm.. I think if I just stand like this.. I might be able to stand upright a little. If you would loosen the hold a little.."

Pia screamed, a pretty high pitched eek!. Fearing she would be speared by a half dozen tentacles, she pulled up her legs, clamping her thighs shut, as if to protect her pussy. This obviously meant she was no longer standing on the ground, but was rather hanging by her arms, suspended by tentacles. Her movements put her in a swinging motion, moving back and forth. Her breast rose and fell, straining against the corset.

With small modifications, one could imagine this as a scene from a burlesque house, a woman in a revealing costume on a swing.

"Please! I can walk! Just let me down, and I will try again!" Pia protested. Her legs were pressed together and pulled so high, she could feel the smooth heels of her boots against her pussy and butt.

Unbeknownst by Pia, her nipples were now peeking out, pink buds and pink areola bold against the skin of her round hills.

OK. Fine. One last try..

Pia really had to force herself to pull herself together. It was pretty hard, as every Instinct of hers was very much on the defensive. Still, MsSaika probably had a point, Pia regretably had to admit. Her kinky substitute teacher turned tentacled horror was probably the kind of person who did sit Down and reflect on the relationship of prey and predator on the island, making little mental notes about exactly what caused one to Catch attention and another not to. Pia would be studpid to dismiss her completely. Both physically and personality-wise, Pia knew a ton of other girls who outshone her. Yet Pia did catch more than her share of attention from monsters, and, more enjoyably, she sometimes caught the eye of other girls as well.

Maybe this was part of the reason.

OK, PiaGirl! Do it!

Breathing deeplu in and out, Pia fought just about every instict and extended her legs, slowly lowering them to the floor.

Tap!

One har little boot struck the floor.

Tap! Another followed.

Natsuki was bloody devious, she had to admit. If Pia followed her insincts, she would, as Natsuki had pointed out, make a more entertaining prey for her. If she did not, and instead tried to follow instructions, Pia had no doubt that would lead to more fun for Natsuki down the road. Still, what could she do but play along.

Pia straighened her back. Closing her eyes, she tried to imagine herself at a cliff by the sea, readying herself for a dive, trusting herself despite being about to launch herself into thin air far above any surface. She just har to trust her legs and those damnable heels the same way.

The constant touch of tentacles gave Pia goosebumps. The feeling was something between creepy and sensual. Tentacles did not move like hands, guided by tendons and joints. The were basically long, complex muscles. Like a tongue. That made their touch so much more intimate. The worst part, and the most exiting one was that Pia could pretty much feel how Natsuki was getting more eager and aroused by this. Maybe it was her brain, maybe something in her nature as a voluptarius, or maybe just that the adrenaline and the proximity made Pia hyper aware of how her captor felt. She did not pause to reflect, but she did not have to turn and look to understand how this affected her captor. Natsuki was no doubt savouring each touch, much like Pia imagined her admiring the color of a rich wine before sipping, or feeling the texture of an expensive garment before trying it on.

But the die were cast. Pia had to keep playing along. She had to prove she could, as they say, walk the walk.

"Eeeeeek!"

It did not start of as a confident strut. Indeed, if it had not been for a swift and helpful tentacle, it could have ended with Pia on the floor at the first step, possibly with a strained ankle or even a leg fracture. Luckily, Pia was scooped up a split second after her right leg began its slide leftwards. The next step was not elegant, Pia still struggling with refinding the balance after her near disaster, and would probably have found herself on the floor without assistance.

Step one and two, however, were definitely steps. Tap. One foot up, forward, down. Heel and point on the floor. Tap. Next foot. Pia made herself suppress her instinct to use her arms for balance, and let her hands rest on her hips.
