Thrusting back and forth with its three tentacles, it simply kept on moving as small bulges moved from the base within the vent and down the tentacles in her anus. Traveling up into her stomach, it began to spew more of its semen into her until it could expand her stomach to the point of having the tentacles move around a bit and add a bit more of their body in.

The monster itself began to loosen its grip onto her body as it must've realized that it can't bring her into the ventilation shaft. Lowering her body slowly to the ground, as it pumps its fluid into her rear end. Its own body began to pull itself out of the vents and crawl down the wall to the ground, its body appeared to be a long worm like form.

"UH! AH!” Andrea could not see the tentacles entering into her backside. It felt impossible long with the three rotating into her spreading her ass to it's limits. She had not seen that bulge flowing through each tentacle but felt it when it collected against her ass.

“NOOOOOO,” stretched to her limits globs of semen gushed into her. The three packages of seed fought to be first but zipped in one after another. Her belly inflated as one gush after another after another hit her inflating her belly even further.

There was certainly no way she was going to fit into that vent now but it seemed to change tactics. Feeling it's tentacles still swirling inside her she was lowered slowly. That hold slackened but had not quite released her though she was confident that she wouldn't have gotten very far.

Instead of drawing her into the vent it came out. More worm-like then spider she panted there, staring at the mass of slime as it crept down. Like a magpie it seemed to have her in a hypnotic trance before striking.

Andrea knew she should run but had no strength to even try. She simply watched and waited for it to act once more dreading that decent as if by coming forth now it meant that he was serious or she had been properly prepared for what it had in mind.

The mass of flesh that came out of the vents, moved a bit faster which allowed it to touch the ground before she could. Moving underneath her like a bed being laid out as it set her down basically ontop of it. While the tentacles inside her slowly finished unloading their juices into her stomach they began to swirl around like they were stirring the fluid inside about.

Its movement was like a slug, slowly shifting down the hallway. Though it really didn't have a destination, it simply moved about carrying its prey on its 'back'.

It was soft, squishy even as she was set upon the worm-like mass that poured out of the vent. Where was it taking her? It was stirring up the juices that had been deposited inside her as if it were mixing a drink. It was flowing down the hall too, it's destination had been unknown to her at the moment though she looked behind her seeing the hallway that it was heading.

Empty. In front off her was the hall that they were retreating from. She then looked to her side at the floor. They weren't going too fast but bloated as she was she knew that she wouldn't get far. Even if she did this thing was so lodged inside her that she wouldn't get far any way.

So for now all she could do was endure the slow ride to who knew where ...

The monster moved, its destination was somewhere either in a secluded location or an open area where it could continue on with its final part of the meal. Slowly making way to the biggest open spaces that's in this school it could find, the main lobby. Though from there it would most-likely leave the area in search of more pray.

While moving, a tentacle emerges from out its side and wraps around her mid-torso just above her bloated stomach. Pushing down as though it was trying to squeeze out the fluids that it poured inside like it was preparing to make more room for another round with her.

With the tentacles inside her stomach, stirring up the semen that was pocketed there. They began to pull backwards, somewhat forcefully back like they were being pulled out back through the intestines while continuing to rotate around each other.

So much for even thinking about how unfeasible fleeing was. Now that wasn't even an option as a tentacle pulled her down to her back. It squeezed and flowed down her body slowly as if attempting to push the plethora of seed out of her. It hurt being compressed in such a way but not as rough as the two spinning about the insides of her stomach not even halting as the other compressed her squeezing out some of that essence that poured out of her in droves.

The back of the thing had been saturated as well as her thighs though there was still a lot buried inside her it made far more space inside her at the same time.

“AHHHH!”

Their journey was still slow but distracted by all this she stopped attempting to figure out where they were going singing out as it continued to churn and press inside her.

Pushing down its tentacle that forced some of it seed out of her inflated pussy. Making room for when it wants deposit some more inside of her. While the tentacle that is around her stomach kept a grip to ensure she doesn't try to escape even in her current state. With the tentacles in her stomach pulling back ruthlessly in a slow motion backwards out of her intestines, spreading the hole a bit wider as it moved along to leave her rear end.

Finally reaching the main lobby, the monster moves over and plants itself right in the center of the room. This allows it to stretch out some of its body as it moves a new large tentacle out from the rear of it worm like body.

AH! AH!” She panted when she could, the squeeze of that tentacle made it a bit difficult to breath as it literally squeezed that seed from her as if she were a sponge that it was wringing out. It did fine work in getting a plethora of that substance out of her as it thrusted and churned those other portions instead her.

When they stopped they had been in the main lobby. It appeared to grow as it spread out though tear filled eyes widened when she at last saw the size of the latest tentacle.

Holy shit!!! She screamed in her head as soon as she notice the latest appendage. That was the reason she was being emptied out? At once instinct kicked in to run but it held her fast, there was no escape for her and her eyes could only settle on that massive portion of it's anatomy as her heart pounded against her chest.

Spreading its body out as it came to a halt in the lobby several of its tentrils moved out and wrapped around support pillar, allowing it to keep itself and its prey from moving. While leaning some of its body upwards having her somewhat be set up like she was sitting back in a chair.


The one tentacle moved over and begun to press against her pussy entrance. Though it didn't wait for too long before thrusting in roughly, pushing all the way to her cervix walls. The tip encircling around the entrance before for the tentacle pulls back. Pulling the tentacle back to the point where only the tip remained in, with it taking a few seconds before plunging the tentacle back in a full force.

Finally the tentacles in her rear pulls out of the hole, allowing some of the white fluid they poured in drip out.

It fanned out and secured itself while bulging and enlarging a bit those most of this caught hr off guard hr attention had been focused on that large member. “No! Ah!” She squirmed in an effort to get free but it was no good. Soon she felt that large member press deeply inside her. She cried out feeling it go deep inside before drawing out, thankfully not all the way as it was still inside her, still stretching her apart and thus keeping her spread opened.

It still hurt as it thrust back in tough not as much as it would if she took that thrust time and time again. Blue eyes shed those tears within and they fell from her eyes rolling down her cheeks even as she felt cum trickle out of her ass as it withdrew from her body.

Her hands bunched up into fists in an effort to cope with the pain she now felt. She did not attempt to squirm so much now that it was filling her time and time again but she did wiggle as much as she could for her own comfort. The situation wasn't much better though

“AAARRRGGGHHH!” She cried out panting with each thrust it made inside her core as it raced to fill her.

The large tentacle that thrust into her continued its rough treatment, slowly after every thrust it became a bit more rougher as it dug in deep to her cervix wall. Like it was threatening once again of pushing into her partially filled womb. As it pulls out, it slightly changes its angle of thrust as it goes aims to press against every part of the inside of her pussy.

Slowly the monster with its learning capability observed its prey, learning of what it can do for its future hunts.

Thoughts of it being self aware had escaped her at the moment. There had been too much going on to contemplate that as it pushed into her. She cried out each time wishing for help but knowing that none would come and even if it had there wasn't much that it could do any way.

The angle varied though it was pressing in deep and hard. Roughly changing angles it was as if it was seeing what the limits of her body had been. Or had been like a child taring the wings off of an insect for shear amusement. She could not say either way, her focus was on enduring the moment.

It pushed into her, she always felt full with that large member inside her. Regardless of how it altered the angle it still brushed against the right portions of her. There was some pleasure, mostly pain, though the build up of release was natural and something she could not stop.

“AHH! OHHH! S-STOP!!! URGH!!!” She squirmed as it continued the assault, the inevitable happening as she came among all the torment.

(Sorry for major Necro-bumping. Just came back from a long vacation going through the thread, going to finish this up with this last post.)


The monster continued its relentless thrusting on the caught prey, changing the angle of its thrust after a few minutes and just thrusting. At this point it seems as though the monster was just moving mindlessly with taking in her fluids and fucking her endlessly. Observing her reactions as it moved back and forth. With every drop it takes, it grows stronger, and more intelligent. With every drop it evolves.

And everytime it evolves, it hunger increases.

This monster continues it assault throughout the day, mercilessly. Taking every orgasm she releases. While its own build up had slowed over time, it does release its own seed inside her. But with the time that passes. It could only get around three more shots inside her before its own body had dulled. Either if it was boredom or the decision that it took enough energy from its current pray. It was decided to move on.


With one final shot of its seed inside her womb directly, the tendril pulls out and slowly morphed backwards into its own body. Loosening its grip on her body as it began to take its blob-like, and shifting out from under her. Leaving the girls body on the ground with her stomach inflated with its semen.

The monster observed its surroundings and noticed that it was well past nighttime, and with the knowledge that it had gained. It could tell that the day was going to start soon, so it was time for it to move on to ensure that it won't be found.

Moving on the monster made way for the hallway that it came from. Heading down in hopes of finding more prey to feast upon.

(no problem, all of Steph's threads went cold, I'll add her last post to before having the thread moved)


No one came. She was undiscovered leaving the monster to do as it would to her young body. Time lost all meaning, her struggles stopped as she lost the energy to keep up, to brake free. Her insides kept getting filled, cum deposited in her again and again to the point that it looked as if she would give birth.

When no more could fit it still went on. Time and time again she past out. For how long she had not known but she would wake either from pain or pleasure as it vigorously moved within her. By the time it had finished with her Stephanie was left spent on he floor, discarded and barely coherent to the fact that everything had stopped.

Panting, eyes fluttering she had no recollection of the clean up services arriving or taking her to the infirmary. She was in and out of consciousness for a bit but never really processed anything At worst she might recount the ordeal in snippets, a bad dream perhaps? A nightmare? At best she wouldn't recount a thing ...
