The incredibly strange feeling of bathing in larva prickled across her mind and skin despite the distraction and it drew out of her a deep, pleasurable all over flush. She shivered with the perceived difference in temprature between her own hot skn and the cool tendril as it pushed her bra aside, coming into direct contact with the globe of flesh and sensitive nipple.

Anne gasped as it did, her mind forgetting for the moment the mirror of her lips as her nipple hardened instantly, pressing against the stone. She felt like she was baing manipulated by many different people all at once, her arse being kneaded expertly by "hands" that were perfectly shaped to her, her right breast being squeezed in much the same way and the featherlight touch on her lips. Each motion sent sparks shooting through her blood and she found she wanted more.

Unknowingly mirroring Anne's desire, the crystal entity wanted more, too. But it was near the limit of its current coordinative ability. For the time being, they would both have to be satisfied with the sensations generated by its current explorations.

Corundus pressed its 'tongue' tendril forward, parting Anne's lips as it sought entry to her mouth. The 'lips' it emerged from followed suit, pressing against their mirror-image. The feeler attending the girl's chest grew a second branch that encircled her other breast. Both branches squeezed and rubbed their respective targets continually, their very tips flicking over her nipples again and again. The 'fingers' on the student's rear continued to mold and tease her buttocks.

Anne was desperately horny, the alien crystal in her blood flowing faster and faster around her body, the rocks manipulations of her sensitive body driving her to want more. However, immobilised as she was there was not a single thing she could do about it aside endure. As the tips of the feelers dragged across Anne's nipples she let loose a soft moan, creating the opening that the tendril at her mouth had been looking for.

Corundus leapt at the chance to finally enter its captive's mouth. It slid its 'tongue' tendril into the moist, warm opening eagerly, careful not to scrape over her teeth. Once inside, it began to explore, rubbing against her tongue and palate. The heat was exquisite and was only enhanced by the wetness of the girl's saliva. It was the most pleasant sensation Corundus had felt yet.

Once again, as the crystal alien became more involved in a particular aspect of its explorations, its other actions slowed or lost focus. Nonetheless, its other feelers continued to play with Anne's rear and breasts. The more Corundus practiced executing multiple actions, the more skill and confidence it gained. Perhaps soon it would be able to add another feeler to the mix.

As the smooth crystal ran over her massively sensitve lips and slid over her tongue Anne's eyes opened wide as a new set of sensations overwhelmed her thoughts. She could feel the smooth texture on her lips and tongue. The taste was simple, like that of clean glass but it came with it something else that Anne couldn't describe fully.

The feeling (for want of a better term) was like how you would imagine two separate tides of rock moving towards each other and instead of slamming together and cracking, they merged, becoming at once together while remaining separate at the same time. It was like two lovers intertwined in body, heart and soul - but where humans would merely wax poetic about such an occurance Anne, for the briefest of instants actually experienced it.

It quite took her breath away and at the same time she would never be able to explain what she felt. Instead, lost in the wonder of the moment her body relaxed entirely, being born on the gentle motions of the being that held her.

It didn't last more than a moment however, as the feeler in her mouth continued its exploration and touched her tonsils. Instantly, her body went from a relaxed pose to tense, all her muscles pulling at once away from the encasing rock as she started to gag around the invading tendril.

Corundus would have assumed that its captive had just started fighting again, but its recently acquired limited knowledge of human biology told it something else was wrong. So, instead of pressing forward, it immediately pulled its 'tongue' feeler out of her mouth.

The entity continued to gently massage Anne's breasts and buttocks as she recovered from the gagging fit - at least at first. But, as the saliva coating its 'tongue' seeped into the stone, another flash of insight struck. Jumbled bubbles of half-coherent information assaulted Corundus' mind. It froze for a moment, reeling from the shock.

As the event passed, the crystal creature became aware of two things: first that the girl had become aroused and desperately wanted to be touched in places it had so far avoided; second, she might react differently to a differently shaped -and less active- object in her mouth.

Corundus' literal hardheadedness wouldn't allow it to switch targets so readily; it wanted more of the moist heat of her mouth now, but in a way that would hopefully keep her from gagging. Perhaps if she could be enticed to take the lead in the mutual exploration, she would naturally avoid such unpleasantness.

Corundus slowly re-formed the feeler in front of Anne's face. Gone was the strange lips and tongue construct, replaced wholly by a simple tapered cylinder. Tailored specifically for the girl's mouth, it was meant to seem 'comfortable' for her to suck on. Corundus slowly waved the object in front of Anne's eyes to make sure she saw what it was offering. For the moment, its other feelers were still as it concentrated on its experiment.

Anne's choking subsided quickly once her mouth was free and her chest heaved. She hadn't expected that! Quickly though, her breath returned to normal and for a moment she was completely puzzled at complete lack of any sensation from her body. The rock had completely ceased all its motion and it oddly felt like something was missing!

As she looked up she was greeted by the same tendril (or she assumed so...) but instead of trying to enter her mouth it just hovered there, as if waiting for something.

She paused, watching it. It seemed to follow her mouth, far enough so that it was obvious to her eyes but close enough to... what? She recalled, not in words but in feelings how she felt when it last invaded her mouth and she found her lips parting, gently as she craned her head forward taking the cool stone inside her.

as before, as it ran over her lips she shuddered with pleasure, the nerve endings sending tingles throughout her body and she moved her head a bit more forward, letting the crystal slide over her tongue again, still moving slowly, partly out of care but partly from the fact that it felt wonderful in her mouth.

The experiment seemed a success. Corundus was pleased, and for a moment, it simply enjoyed the heat of Anne's mouth as she began to take the tendril in. However, it soon noticed how awkward the motion was for her in the current position. Suddenly the alien realized that the girl's body was not as malleable as living crystal.

What followed was a flurry of motion as Corundus retracted all its tendrils. Then it flowed and shaped around Anne, shifting her position as it went. When it had finished, the crystal entity had become a sort of reclining 'chair' for the captive girl. It did its best to seat her comfortably on its surface, once again molding to her body.

Though it still held her by the ankles and waist, Corundus freed the girl's hands before it repositioned a feeler before her mouth. As before, the comfortably sized almost popsicle-shaped object merely hovered there, waiting for her to take it in. At the same time, tendrils slid up her legs again, flowing easily down beneath her rear to form a web of massaging fingers under her clothes against the bare skin of her buttocks.

For Anne, it was unexpected and more than a little unsettling. She was just getting used to the object in her mouth when it was rapidly withdrawn and the entire rock that she was on moved dramatically under her. The sudden shifts made her want to grab hold of something.. anything to keep her balance and she struggled trying to find some sort of hold.

She needn't of worried however, as the living rock moved her gently, without stretching, rubbing or pulling any of her limbs in a way that they weren't supposed to go.

As she was settled in a sitting position Anne shifted against the hard surface and she was amazed as it moulded itself to her shape. letting her rest comfortably. As she did though that same tendril held itself to her face.

Despite her heated state, and the resumed motions on her skin though she was most reluctant about doing anything with the waiting tendril, the shift and momentary panic had dulled her lust and she looked around trying to make sense of what had just happened.

Corundus was not entirely surprised that the sudden shift had disrupted Anne's focus. For the moment it simply left the upper tendril hovering near her mouth, a constant reminder of the pleasures it could provide.

However, other tendrils continued to work on the girl. For one, it likely felt like she was sitting in a pair of giant crystal hands that constantly squeezed and rubbed her ass. But elsewhere, another pair of feelers began to grow on either side of her neck, creeping downward under the neckline of her shirt then under her bra to curl around her breasts.

As Anne sat she could feel her arse cheeks manipulated by the living rock, the motion being entirely pleasent but she tried to ignore it, trying to focus her mind away from the motion and to what was actually happening.

It was difficult. The motion was like lying at home on your bed of heated magma, being buoyed up by the currents under you, occasionally letting yourself dip a little deeper into the hidden eddies and swirls, the current running over your top towards your breasts where it would...

Anne blinked, and saw the sky, which was the cerulean blue rather than the slate red streaked grey she had seen for a moment. What was going on?!

The feeling however, of the magma flowing over her shoulders, down towards her breasts was still there though... It was a wonderful feeling, intoxicating and she revelled in it. It actually took a couple of moments though before she realised the cause. As she did she pushed herself up, against it, but, as she did the extra friction burned through her body, sending waves of heat down her front causing her nipples to harden and her pussy to clench slightly on itself.

Despite the image having faded again it had re-awoken her body and she laid back into the seat with a breathy sigh of pleasure, basking in the heat from the sun for a moment.

To Corundus' relief, the young woman relaxed and settled back against its surface. She seemed to be returning to her accepting state, so it decided to press the issue of exploring her mouth again. It nudged the attendant tentacle against her lips, giving a simultaneous squeeze of both her breasts and her ass cheeks. Then all motion stopped once again as the crystal entity gave an ultimatum of sorts. It just hoped its captive would understand its intentions.

With some of her former heat back in her veins the gentle nudge of the tendril on her lips only added to the pleasure of the rays of the sun. She may have laid there letting it stroke across her lips, her breasts being squeezed but abruptly all motion stopped.

The lack of motion jarred her to motion. She had been quite happy basking in the motion and her eyes flicked open, seeing the tendril stroking her lips almost insistantly. Struck by a odd compulsion she couldn't name she her head forward and kissed it, letting it slide into her mouth slowly. The feeling was intoxicating as the smooth stone slid across her lips.

Corundus pushed the tendril into Anne's mouth just far enough that she could 'service' it easily without too much motion, yet could still pull away if it became too much for her. Since she complied with its unspoken demands, the crystal entity rewarded her immediately with the motions she found so pleasurable.

The 'fingers' beneath her bottom squeezed and molded her cheeks, randomly throwing in a good rub now and then. Meanwhile, above, the tips of the tendrils encircling her breasts slid back and forth over those lovely mounds, grinding over her nipples every time they passed.

But that wasn't all. The crystal creature also produced another feeler between the girl's legs. It slowly slid along her left inner thigh, moving directly toward the apex of her legs. When it reached her crotch, the tendril pushed her panties aside, revealing her moistened sex . . .

Anne was enjoying the feeling of the smooth rock sliding between her lips immensly, each motion sending tingles down her spine and enhancing her own lust-filled mood. Her free arms snaked up and took hold gently of the rock tendril, holding it steady as she rolled her tongue around the end, relishing the smooth texture. With the motion back around her body she found herself sinking into a mire of soft motions each one letting her bodys internal temprature soar.

She felt the rock creep around her legs, the cool rock leaving a trail of goosebumps as it travelled along her inner thigh, spreading to her soaked netherlips as her panties were pushed aside, letting the suns rays and the cool air spread directly across them, elicting another pleasurable little shiver from the captive student.

Suddenly, her eyes flicked open from their half-lidded bask in her own bodys pleasure as she belatedly realised what was about to happen.
