Success! Corundus' feeler slipped under the rougher-textured flap and continued to slide up the creature's leg. With the amount of wiggling Anne was doing, it was difficult to follow a straight line, but the crystal entity tried to keep its progress smooth anyway. As it explored, it was happy to note a greater concentration of warmth in this hidden place. So much so, in fact, that it was spurred to spawn another tendril and send it questing up the girl's other leg, beneath the covering layer of course.

Meanwhile, it wasn't long before the first feeler encountered another texture change. Not as rough as the texture of the outer layer, this new layer had a different sort of softness to it. With an intuitive leap, Corundus hardly paused, diving under the new layer it had found and sliding its feeler up onto the firm mound of the girl's right buttock.

Her failure to stop whatever the hell was going on didn't help her mood one iota. She twisted, she turned, she wriggled and writhed but nothing she did managed to let her limbs move fractionally, the tiny amount of give each moment she struggled being almost instantly resealed.

As the tendril of stone crept along the inside of her panties her struggles once again redoubled. She threw everything she had into each twist, every motion being brought with pain as her flesh pushed and pulled within the rock as she tried desperately to get away.

Her struggles, however had no effect on the rock, and despite her spreadeagled pose, were tiring her rapidly, and in the back of her mind, the bit that could still think rationally despite her animalistic attempts to escape knew that she couldn't keep it up for much longer. Gradually, as her struggles slowed down from a mixture of the pain in her limbs and her pending exhaustion her mind re-asserted itself, trying to work out how to get away from a rock that was slowly drawing her into itself. She was scared, and really didn't want to be sucked into a rock like quicksand!

Corundus greeted the lull in the creature's struggles with mixed emotions. Less activity on her part meant that the crystal entity could move its feelers where it wanted more easily, but that less heat would be generated by her body. Still, if she were still, it might be able to investigate the moist heat that came from the same place as the sounds she made.

Corundus slowly formed a feeler tendril in front of Anne's face. As it grew, flowing upward from the stony surface of the crystal entity, it moved toward the girl's mouth. Meanwhile, it continued to explore with its other tendrils. The first continued up over Anne's rear, soon exiting the waistband of her panties near the small of her back. The second spiralled upward around her left thigh, though it still managed to miss the treasure trove between her legs, slipping under her panties near the outside of her hip.

The feeling of smooth, cool rock under her panties was shocking and certainly unpleasant. But it was eclipsed by the the tendril of living rock that formed right in front of her eyes and started to grow on itself, flowing in mid air towards her mouth.

Another shriek filled the air and Anne violently wrenched her face away from the approaching tendril, her back arching sharply. The motion caused her already wrists to pull once again slightly her rock-like prison. The violence of her action caused the already raw skin to scrape across the edges of the rock cracking the skin and leaving a small trail of red blood on the dark rock surface.

Corundus was a bit annoyed by the creature's violent reaction. Having decided to investigate the source of the sounds and moist heat, it was now determined to do so. It prepared to loop a tendril up around her neck to pull her head back down, but suddenly, it became aware of a new sensation: a hot wetness was smeared against the stone 'restraits' holding the creature's fore-limbs.

Even as the red liquid seeped into Corundus's surface, small traces of the alien crystal were introduced into the girl's wound. The unfamiliar term bloomed in Corundus's mind; suddenly it had some knowledge of this human species. All action on the part of the crystal entity suddenly stopped as its consciousness was overwhelmed with bubbles of information.

Anne's struggle and accompanying hiss of pain as her skin scraped against the rock was cut short as the tiny amount alien matter entered her shallow wound. For a split second she felt the strangest feeling, like her arm was both miles long, stretching impossibly, but, at the same time it shrank inwards. It was incredibly disconcerting and as she struggled to cope with the inhuman sensory input her vision greyed.

It lasted for only a moment but felt much, much longer to Anne. With a violent exhaltion of a breath she hadn't realised that she was holding she slumped to the immobile crystal surface, her skin feeling feeling blazingly hot despite the cool surface that she was lying on. As her mental facilities returned she was shocked to see that the small rupture in her skin was gone, as was most of the rawness in her wrists - just a tiny amount of redness being left to show. As she shifted to get a better look at that her behind shifted against the immobile rock that trapped her. The motion against her heated skin made her gasp out loud. It felt unbelievably GOOD! The sensation sent shivers running straight up her spine and she wiggled her rump again, being rewarded with the exact same pleasure.

When Corundus' senses cleared, it was surprised to find the young woman's motions had changed. She didn't seem to be struggling so much as rubbing against the tendril pressed against her behind. This and the increased heat output of her body momentarily distratced the crystal entity from its quest to invade her mouth.

Instead, it focused on the area in question, slowly rubbing the tendril over the pert mounds of her buttocks. Though its newfound knowledge told it there was entrances nearby that might provide greater heat, it was content for the moment to explore the outside of the girl's body.

Anne was lost in the sensations her body was flooding with as the alien substance mixed with her blood. Whereas Corundus' learnt about Anne, Anne also learnt about Corundus. Unfortunately the sheer sensory input was too much for Anne to take in leaving the information scambled and inaccessable in her mind not aided in the slightest by the fact that Anne wasn't a lump of rock and thus had different ways of perceiving the world... And to make it worse for her, the side effects were intense.

She gasped again as the crystal stroked up her bare skin of her buttocks, feeling like it was creating a trail of glorious fire that made her skin prickle with delight. Her mind, already blindsided sank deeply into one thing it did know as it tried to cope. Pleasure. Since the the mere touch of this rock gave an enormous amount of it, for the moment thats all she could think about.

Instead of resisting as she had been scant minutes before she pushed herself onto the crystal feelers, the sudden motion pushing the crystal strands back slightly, the hard pressure on her bare skin making her shiver all over.

Corundus was surprised and fascinated by the sudden change in the girl's behavior. Though it had gained much knowledge about her physiology (quite a bit of which it didn't understand since it still needed a basic knowledge of biology), it hadn't learned anything about psychology. Neither could it know how its substance had affected her.

Given the crystal entity's single-mindedness, it focused even more on the girl's rear. To better explore the area that had produced such a strong reaction, Corundus funneled more of its substance up the feeler, bulking it up to push harder against Anne's flesh. Soon, smaller finger-like tendrils branched out of the main feeler, spreading over her ass cheeks, rubbing and squeezing the lovely mounds. Corundus reveled in the sensation of heat from the area, eagerly exploring every inch.

As she pushed back she felt the oddly liquid rock mold and shape, squeezing her arse like it had huge hands. The cool, oddly smooth surface felt odd but oh so right. With a smile she carried on slowly rotating her hips, letting the sensation build, her nerves flaring to the point that she was almost vibrating with pleasure.

It was wonderful, and she didn't want it to stop although at the same time she rather wanted contact with various other parts, one of which was already moistening with the attention her behind was getting.

Soon enough, Corundus began to crave more heat. It remembered the other feelers it had already formed and resumed their actions. The one that had spiraled up Anne's left leg began to crawl upward and around again, passing from her hip to her belly as it flowed along it's course. Unfortunately for the girl, her captor was not yet ready to explore the lower orifices of her body.

It was, however, still very curious about her mouth. Though it now had some knowledge of what to expect, its interest had already been peaked by direct experience of her screams and breath. Perhaps the girl's change in behavior would allow it to explore there now. It repositioned the attendant feeler near Anne's face and began the push toward her lips once again.

In the meantime, Corundus continued to play with Anne's rump. It's motions were less focused, however, as some of the crystal beings attention was diverted to the other endeavors.

Anne was enjoying the attentions on her buttcheeks immensly, her body rythmicly moving back and forward against the cool rock feelers under her underwear. So much so that she missed the feeler moving towards her face. The first she noticed was when one of her forward motions let her lips brush delicately across the smooth surface of the feeler.

She hadn't relised it, but her lips, full of nerve endings as they are were massively sensitive. The light touch sent a glorious wash of pleasure across her cheeks, around the back of her head and her straight down her back. She let lose a long, breathy sigh of pleasure, blowing hot air across the feeler before moving her head back, kissing the tendril gently as she relished the glorious feeling.

Such a fascinating reaction! Suddenly remembering the earlier event involving the girl's hand, Corundus formed a mirror-image set of lips on the end of its feeler. Pressing them against Anne's, it tried to follow her movements while reveling in the moist heat of her breath.

The crystal entity's other motions slowed somewhat more as it became more involved with exploring the girl's lips, but it still managed to absently squeeze her ass cheeks. Its other feeler straightened out as it slid up her abdomen, snaking slowly under her clothing toward the pert mounds of her breasts.

Anne felt the change of the tendril as it shifted shape against her lips, pausing, puzzled. The tendril of smooth rock had altered its shape to a mirror image of her own. It held, so close to her own lips that she could have kissed it, but instead she inched her head forward and stuck out her tongue, giving it a tenative lick. The taste was bizzare tasting like nothing she ever had before. It made her think of superheated larva when you could live happilly, basking in the roar of living stone...

Anne stopped all motion at the feeling. It didn't come from her but at the same time it did. She felt things that she had no point of reference for but at the same time it was as if she knew it all her life. She blinked, puzzled as she tried to reach into herself to figure it out.

She was distracted though as another branch of rock slid up her stomach, causing her to jump at the touch as it threaded under her top, slowly approaching one of her breasts. For a moment she thought about fighting against it but it really did feel good!

Puzzled by the girl's sudden stillness, Corundus nonetheless pressed forward, mimicking her most recent action. Its crystal 'lips' parted to allow a crystal 'tongue' to slip out. It slowly closed the slight gap to Anne's lips, moving with the intent to gently rub against them.

Simultaneously, the feeler sliding up her torso slipped under her bra between her breasts before beginning to curl around the right mound. The motion of the rock fingers on Anne's bum picked up again, slightly; they squeezed and rubbed more vigorously as the crystal creature became more used to doing multiple things at once.
