His seductive tone only pushed her to further heights of pleasure. Her cunt was clamping on the cock inside, enjoying every moment of its inviting pumps. Tendrils danced over ehr sensetive spots, leaving her no breath for what was to come. She gives a soft scream as her body climaxes. It pulsed greatly in her being, causing a dreamy like state to cross her face. It felt so heavenly, almost wanted. But not quite wanted. Never the less, she couldn't stop herself from screaming in bliss.

It took a moment for her orgasm to fade and leave her weary. Her arms that had held her up gave way and let her fall onto the bed. She pants softly from the aftershocks, completely drawn in her own little world of heaven and pleasure.

The monster merely shook his head. "Enjoying, are we?" He positioned his cock near her ass now, her state of muddled arousal leaving it sloppy wet, and enormously in need of a good fuck. The tentacles still pleasured her, as his cock pistoned straight into her wet cunnie. "My turn for some fun." That was all he could say as his cock rolled in and out of her in a steady rythm.

Her head weakly turns to the pressure building to her ass. He was going to push it in there? She had little to react before she pushed it inside. Pressure, but little pain since it was lubricated with nectar. She was enjoying, in her state of muddy mindset, she was purely enjoying being ravaged.

Her head quickly whips around and lets out groans as he moves it in and out. She felt herself stretching, but it felt so good. Why did it feel so good to be opened like this? Her mouth hung open with small trails of drool. Her hands grip the bedsheets on a whim. Her ass being stretched never felt so good before.

"Let's see now. How do you like it up here?" 13 speared his tentacle straight into her ass, wanting to see how far she could go. His cock was also starting to really get hard- that meant it would cum anytime now. Kind of a pity, though. The look on the girl's face could've turned him on fifty times over.

"Eh-ehhyyaaa!" she cries out when the tendril surges into her tight little ass. Her eyes squint shut to try and block the pain and pressure that was slowly building, but it did little good. Yet somehow this pain didn't seem so painful in a sense.

Teeth clinch shut, she too wondered how deep the appendage could go. Hands grip the sheets tightly until they turn as white. Breathing was becoming difficult and she soon found herself sliding back until she was laying with her legs in the air.

Gurgled moans escape her diaphragm, thoroughly enjoying the assault the monster was pushing against her.

13 smiled as her body finally began to give to the fluid he was using to subjugate her to his primal will. He was happy to pound her over and over. He would be happy to cum inside of her, knowing that he wouldn't have to feel too bad for her. But his conscious nagged him every once in awhile. Like now.

13 couldn't help but notice how all that she could squeeze from her throat were just moans. How bad could it be?
It suddenly didn't matter to 13. He was getting back in the mood to pound the bitch in heat.

Throbbing sensations of stimulation make her eyes roll to the back of her head. What was the point in fighting when it was going to end up the same? Maybe her conscience would tug at her in the end, but it would tug her any ways for not being able to escape...

The cock felt like it was getting biger. The monster was going to cum soon. How good would it feel to have warm liquid shooting into her tight walls? The thought made her shudder inside.

The thickening only made it more unbareable not to scream from the pleasure. Her tight tunnel ripples again and again with each pounding it took in, embracing the tendril to its fullest to have ultimate stimulation. She was already going to cum soon. Even again, it felt like it was a first.

"Came again, huh slut?" Thirteen panted as he continued to piston in and out of her, feeling her infectious pleasure forcing her to pound right back. She was coming to love it, Thirteen could tell. Her mind was probably a haze of constant pleasure, her conscious thought lost with each wet slap that echoed from the room following each pound.

He was SOOOOO close. He could feel the building up in his 13 inch staff. He was ready to bathe the girl in a shower of white seed. He turned himself even harder by wondering how the slut would look covered in his cum.

Suddenly, he came. But the cum continued, long after he filled her pussy with it. He pulled out of her and continued to come all over her face and body. He bet her breathing was hotter, and sexier than ever before.

As the monster cummed into her tight slit, she gurgles moans in her drool filled her mouth as the thing pumps his hot liquid into her. Feeling her womb suddenly full in capacity the monster slips out and globs her with gallons of his hot seed. Some caught in her mouth, but it mostly fell on her chest and little on her face. She still looked like a complete as both breathed long and hard.

She falls back limply, trying to catch what little breath she had after such a sudden climax. Drool continues to trickle down the sides of her lips, possibly with some semen trailing off as well. But she was too tired to wipe her face of any semen. The hot liquid still made her walls twitch and spasm from their burning heat.

Wow. She looks way too hot when covered in come. Thirteen watched the remnants of his night's work with pride. He did, however, stop for a second to make sure the girl was just tired, and not choking on his cum. He gently caressed her cheek as he pushed her face to the side, so that she couldn't choke on her own drool. Thirteen was a number of things, but he was no murderer. He hoped she wouldn't be too frightened by what happened in the night. Thirteen was quite pleased that she lasted as long as she did, but he didn't feel quite satisfied. His cum dripped from her naked, hot body, like icing on a poorly baked cake.

"How was it? Nice enough for you?" his voice slithered through the haze of lust and pleasure as he gently leaned next to her ear. "I certainly hope you're ready for more. That's how this school works. You better get used to it."

Her eyes were dimmed in color, unable to register much of the monster's toying words to her mind. They gently advert to look at this monster that had crept into her life, but the emotions playing behind them were unsure of to be understood. Was she sad or aroused? Angry or upset? Only the woman knew what she was feeling...

Drool mixed with her own juices and the aliens dripped slowly from her form, but that was the last thing on her mind. She was weak and tired, but the monster seemed hungrier then ever to be satisfied. She couldn't please the thing anymore even if she wanted to. She had long stamina thanks to this island, but even she was drawing to a close on her energy. It was only a matter of time before she couldn't handle anymore.

Thirteen panted, satisfied with the girl's lewd moans and face. His cum flowed down her face as if she were bathing in a waterfall, the white liquid flowing down her body as the cock began to harden once more. Thirteen's tentacles continued to fondle her. One played a bit more with her clit and two more felt her heaving breasts.

Despite the tentacles, Thirteen wasn't really in the mood to do it with her again. He was tired, but pleased. He did, however, want her to break... in the mental sense of the term, of course. He wanted her to beg for him, to have wet dreams of him...

Nah, too much work. Thirteen finally stopped and slinked away, almost like a wounded animal, but took one look back at the girl. He suddenly felt bad about what he did. He quickly checked to see if she was still breathing, and decided to keep an eye on her. Not literally, of course, just to, you know... keep an eye on her. Thirteen guessed that the only thing that made him less of an animal than his colleagues, was his sudden pangs of guilt. As Experiment 13 turned invisible and climbed up into a corner, he watched her breath. She would be fun to take again. Indeed she would...
