Green-Eyed Monster

And she could see her feelings reflected in the monster's green eyes.

"Are you ready, my sweet?" asked the toothy grin. Una licked her lips.

"Yes," she whispered.

"I'm going to fuck you in a way no human lover could ever replicate. I'm going to fill you up so completely you'll never feel truly full ever again. Are you ready?"

"Yes," said Una.

"I'm going to fill you not just physically, but mentally too, fucking myself into your head and infecting you with sweet jealousy; the sort of jealousy that makes you dare what you otherwise wouldn't, to take what you thought you couldn't have, to be proud of what you truly want, who you truly are. Are you ready?"

"Yes!" shouted Una, "Yes, do it!"

And then, softer, while looking deep, deep into those green eyes, "I want you. I want all of you."

"Lovely," said the monster, and Una had another shiver of fear running down her spine. She had just enough time to think 'what have I gotten myself into' before three tentacles acting as one pushed into her, filling her mouth, pussy and ass.

She would've screamed, had she not just been gagged, but not from pain - it didn't actually hurt, in fact it felt really good - just from the sheer surprise of it all. She'd never been double penetrated before, let alone triple. And her ass was usually a lot more reluctant to let anyone in, but now it felt eager for a fucking. Her mouth was filled with so much flavour she thought it might burst, and she had to swallow and swallow to keep from overflowing with saliva. And her pussy... fuck. She was squeezing those inner walls like crazy, milking that tentacle for a cumshot that was unlikely to ever come, desperate for it to do more than just sit there, but ever so grateful to have it at all.

"More?" asked the monster sweetly, and Una nodded so hard it was a wonder she didn't shake anything lose. The monster giggled, and then - Una's eyes grew as big as saucers; she'd expected a fucking, not this - another set of tentacles joined the first, shooting into her like it was nothing. Her mouth was too full to swallow properly now, and she started drooling, though she could feel her pussy leaking far worse, gushing like a veritable waterfall. She felt impossibly full, and still... still it was somehow not enough. But how much more could she take?

"You still want more, don't you?" said the monster, and then, echoing Una's thoughts, "Wonder how full I can make you? Wanna see?"

Una nodded again, a little more timidly this time, and tried not to tense up while waiting for the next insertion. But it didn't come. Instead the monster showed once more just how literal it could be by materialising the TV screen again - but this time it had company.

No less than nine screens hovered before her eyes, though the middle one seemed to be just a mirror, showing her drooling mouth and her wide, hungry, brown eyes. The rest of the screens, all decked out around the mirror, showed various angles of her behind.

The top centre and bottom centre ones both showed similar straight shots of her pussy and asshole, right between her spread legs, though one was taken from just above the mass of tentacles penetrating her, the other from just below. At the very edge of these screens more tentacles hovered, waiting, waiting. The two screens in the top corners showed her from the sides, the bottom corners from directly above and below.

Then there were the pair on each side of the mirror. These screens were something else: They used a fascinating sort of x-ray, showing just how the tentacles were filling her up, her own body like a ghostly outline around the invading forces.

This surreal display made Una remember, quite suddenly, that this was a dream, despite what her senses were telling her. It wasn't real, at least not in the strictest sense of the word. What she was experiencing didn't have to follow the rules of the waking world. The monster really could do anything it wanted to her. Anything.

Another tentacle coiled forwards, probing her pussy far more tentatively than the first two, but pushing inside soon enough. Her body didn't seem to have any trouble accommodating it, or the next one, or the next, alternating seamlessly between her two openings. She came as the fifth tentacle entered her snatch, and the monster squealed in delight as her pussy spasmed and contracted; it really did love orgasms. But it didn't stop pushing its appendages into her body.

She was already much, much fuller than she ever would've thought possible, and she probably would've doubted the sight before her had she not also able to feel every tentacle so very keenly, every coiling movement sending signals of pleasure to her brain. And still ever more tentacles hovered at the edge of the screens, just waiting for their turn.

Her second orgasm came three tentacles later, as the sixth - or fourteenth in total - wiggled its way into her ass, the other five pushed even further in by its intrusion, even as they tried to manoeuvre around inside her to make room. Her eyelids fluttered and her toes curled in on themselves, quite out of her control, and a heady moan forced its way past the tentacle duo in her mouth as her insides ignited and fireworks exploded in her head. It was a good thing she was bound up so tight, or she would probably have melted into a puddle on the ground.

"Ooh, that was a good one!" said the monster with an almost childish enthusiasm. "What should we do to get more of that?"

Una moaned. It was pretty much the only thing she could do.

"More, you say?" said the monster, acting much like a human pretending to understand perfectly every sound their pets might make. "And faster? Harder? Fuck you with everything I've got? I wasn't sure you could handle it, but well... if you say so!"

In a sudden burst, the tentacles in her mouth pushed into her throat. The ones in her pussy hammered into her womb. The ones in her ass shot all the way into her stomach. She knew it wasn't possible, but she could feel the undeniable truth of it, and she could see on the screens how the tentacles filled her up, how wildly they fucked her, with no rhyme or rhythm, just trying to fit as many as possible, reach as far as possible, make her as full as possible.

And the monster got its wish; she immediately came again, and she didn't stop cumming. Her bulging eyes were glued to the screens in front of her as her quivering, screaming form was fucked, and filled; until she was so full that the tentacles ravaging her throat touched the ones fucking her whole body from the other side, until her insides were more tentacles than organs, until she knew she should've run out of air to scream with long ago, until...

Until her brown eyes started changing. Subtly at first, but faster and faster with every hard stroke of those powerful tentacles. Until finally the eyes staring back at her from the mirror were the same impossibly green ones she'd come to know so well. Those irresistible monster eyes.

"It'll be easier for you," said the monster, somewhere close to her ear, just out of sight. Even in the throes of her endless orgasm, the voice still sent shivers down Una's spine.

"All you'll need is to look them in the eyes; and a bit of jealousy on their part."

Una didn't understand, and didn't really have the mental capacity to try to. Her never ending scream was becoming louder, somehow, like her mouth wasn't blocked by a fat pair of fucking tentacles.

"You're about to wake up," said the monster, wistfully. "Thank you for letting me fuck you, Una."

That was the first time it said her name. Somewhere in the haze of her pleasure, she wondered if it had a name, too. She'd never be able to ask.

"And thank you for all the orgasms, too. I've had a really good time. Now, you have fun fucking as many people as possible for me today, you hear?"

Suddenly all the screens in front of her disappeared, and in their place the monster's face hovered inches from her own. Its mouth was closed, every sharp tooth hidden. It kissed her, softly, on the forehead.

Still screaming, Una woke up, the monster's last words ringing in her ears:

"Happy Halloween."
