Chapter Text
Evan’s job was washing the lab at night. It was hard underpaid work for some kind of company running experiments with, well, he wasn’t actually sure. There were animals–-not that he’d ever seen them. He could hear them, growling or crying out, vocalizing in ways he couldn’t describe, as he worked mopped the floors.
Every night, he cleaned the bathrooms, the labs, the halls, and then he went into the pens, the part of the enclosures the creatures only had access to in the day, to clean them up. They’d usually been mucked out by someone else, so he just went in and mopped the floors and sometimes removed piles of discarded hay or half eaten vegetables or the stray bone, still red with blood.
He never saw anyone else, or anything else. But tonight, after slipping into the third cage, tugging the cart into the doorway behind him, he discovered he wasn’t alone. He hadn’t bothered to check the little reinforced glass window on his way in, but why would he? He’d never needed to before.
But as he was working, he heard a shuffle in a dark corner of the room. Turning, he saw some huge, hulking, furred thing looking right at him. It’s eyes were flashing in the dim light. It slowly crouched down, readying for a pounce maybe, while it watched him.
His heart raced. He had a moment to think, 'oh fuck, I'm going to die,' before he ran.
The cart didn’t move at all as he shoved at it. God, why wasn’t it moving? he thought as he kept shoving hoping against hope it would just move.
It felt like getting hit by a car, the creature’s body knocking into him. It knocked him to the floor. The force of their collision pushed the cart right through the door. With nothing blocking the entryway, it slammed shut.
Evan didn’t pay that any mind. He wriggled against the creature, frantically scrabbling at the floor and the doorway trying to get away. The thing got a mouthful of his shirt, teeth grazing his neck, dragged him further into the room. Evan could do nothing but be dragged.
His shirt ripped down the back as he was dragged along the floor.
The creature breathed hot on the back of his neck, then grazed it’s teeth against his shoulder with more intention this time. He froze, sure he was about to splatter all over the wall.
The thing sniffed at him, mouthed at his shoulder for a few long minutes until he could no longer hold in a thin cry of fear. He was gasping, terrified, sure he was a second away from death.
The creature's wet nose touched his bare back, it breathed heavily against him. He stayed perfectly still, waiting to be eaten. He grunted in shock when the thing licked at him. It took interest in his lower back, licking in long curious stripes. Evan had the hysterical thought that he was a lollipop about to dissolve under this thing’s tongue.
It abandoned his back to snuffle at the back of his pants, then changed position to sniff curiously at his crotch. He kicked out his legs trying to get the thing away from there.
His pants ripped open and he yelped, his ass suddenly bared to the cool air of the room.
"Hey! What are you--" he wriggled, trying to dislodge the thing, only to shout when it pressed its paw to the middle of his back and kept ripping his pants away. He was breathless when the creature pressed its snout to his now bare crotch. The feel of hot damp air against his cunt made him shiver. It sniffed him for a long time, making Evan squirm. Unfortunately, he could feel himself grow a little pump at the attention. Only natural, he thought a little hysterically.
There was a wet sound, almost like a pop, and he screamed but the pain didn’t come. He peaked over his shoulder to see the wolf creature had split open like some kind of fucked up flower, the raw red inside visible, thick muscular tendrils rippling out from the huge maw. He lost his breath all over again, felt a little sick with horror. He was going to die.
The creature got up off him and for a tiny moment, nothing held him down.
He didn’t move. He barely breathed.
The tentacles, fever hot and damp, wound around his ankles, around his wrists, around his thighs. There were so many it was dizzying. They wrapped uncomfortably tight around him. A few of the heated limbs wriggled over his exposed ass, down over his cunt, making him gasp and jolt forward. The tentacles tightened around him, keeping him in place. He let out a tight little gasp at the increased pressure.
One of the hot tentacles breached him. He whimpered. This couldn’t be happening, it couldn’t. He was just supposed to mop floors tonight, then go home to his little apartment, get up in the afternoon and go on a coffee date with a cute guy from the library and then come back into work. This wasn’t supposed to be happening. But the tentacle was pushing inexorably into him.
It wasn’t so big but he’s tense with stress, his body tight and unyielding; a bright pinching pain went through him as the thing started to thrust and his eyes pricked with tears. The tentacle pulled back, almost completely out; he sighed with relief but then another tentacle-–wet and dexterous-–rubbed over him, making grunt and buck. He tried to get a peak at it, it felt bigger than the one inside him now. But it worked over his clit–-insistent and with just the right amount of pressure-–he tucked his head into the crook of his elbow and breathed heavily with unwilling pleasure, instead. It was wet and smooth and felt amazing against him.
It licked over his hole, around the tentacle resting inside him, and he whimpered, feeling now how wet he was, how swollen, no matter how scared he was that he’d be eaten when the creature got done using his body. He kind of hated himself for getting messy and aroused like this. Stupid stupid. Stupid of him not to check, to knock the cart out of the door, to get all hot and bothered while being fucked by a giant wolf monster thing. The thicker tentacle slipped back down to lick at his clit while the other thrust into him gently until he was clenching and aching to be filled with more.
The tendril breached him, pressing alongside it’s smaller counterpart, and this time he sighed. He was embarrassingly wet and desperate for it, already twitching his hips back into the thrusts.
It set up a quicker pace now, impossibly hot and unyielding in it’s rhythm, like maybe it was just as worked up as he was. The thing dragged his hips up so he wass ass up, face to the ground, completely spread out for the taking. Evan made noises he didn't recognize, garbled and choked, desperate. This thing was somehow good at fucking.
We whined when another tendril pressed into him, thrusting in time with others, filling him to aching.
He liked it thick, liked the challenge, liked the way he gets wet and messy when he got fucked with a thick toy and this was--it’s good. Humiliatingly good. He already knew his cunt was going to look raw and wrecked when this thing got done. If it didn’t eat him. And it had been so long since Evan had been touched or fucked anything other than his collection of silicone cocks at home. He wanted more, even as he shuddered at the sick heat and the raw red tentacles keeping him bound in place.
He gasped a moment later when another tendril pressed into his ass. It was small enough that the pinch eased quickly but he still whimpered as it wriggled in him. It worked him open while the other three tendrils kept their steady rough pace. It pressed further into his ass, getting thicker as it went, until he swore he felt it in the back of his throat. His rim was already raw with the stretch.
He was babbling now, a stream of incoherent curses and cries, neither asking the thing to stop nor keep going. It clearly was not listening; all he could do was lay here and take it.
The tendril in his ass pulled out, leaving him pulsing and shuddering, open for whatever the thing had planned next. It pressed another in, blunt and hot and thicker still. Yet another slipped into his cunt a moment later. It hurt now, his cunt and his ass aching. It made him hot and desperate as he bucked back minutely to get more inside him, more and fast, now now, he needed–-
He came–-pain and pleasure cresting-–going rigid with sick ecstasy, barely breathing through the aching orgasm. His own juices dripped down his leg.
The creature withdrew from his cunt–-too soon, too soon he wasn’t done–-and slowed in his ass. He had a moment where he thought perhaps it’s over, maybe it was done with him.
Stupid. Of course, it wasn’t done.
The thing crouched over him, furred belly over his back, horrible huge flower-like maw over his head.
Something bumped his ass, pressing clumsily against him. Then it slipped down his ass to his cunt, rutting ineffectually against it. He gasped, suddenly tense and nervous all over again. It was a cock. This thing was only getting him ready for its cock, which felt enormous and monstrous against him.
He should have been praying this thing wouldn’t break him in half.
It took a few minutes of ineffective rutting but finally the cock caught his cunt and sunk in.
It was fucking huge, the biggest thing he’d ever taken, and he’d taken fists before. He had a whole host of toys at home that would make most people balk with their size, but this is bigger than any of them. He understood now, why it took the time to fuck him with all those tendrils first. He would have torn if he took this first.
The creature didn’t give him time to adjust, just started thrusting in long sinuous thrusts.
It was almost elegant, the way the thing thrust into him, not that he paid attention. No, he was a little busy gasping like a man dying; he might be dying, he thought. He was being split open so wide there was no way he would recover. His belly and holes ached. He wished suddenly, that there was someone there to take a picture of his cunt stretched tight around this cock, of his body taking this merciless thing and not breaking.
He cried, dripping tears onto the brutal concrete floor under him, as it sped up its thrusts, fucking him without a care now. He was overwrought, so sensitive he felt a little like he was being fucked by fire in both holes. He turned his face into his elbow and sobbed, back heaving.
“Stop,” he finally gritted out, “Stop, please, I can’t--please,” he gasped.
The thing stilled, and oh god, came in him. It felt searing, he was sweating, and worst of all it kept going. For long minutes, the cock twitched inside him as the thing kept cumming and cumming and cumming, until both holes leaked around the enormous cock and tentacle.
When the cock, finally gone soft, pulled out of his cunt, cum spilled out of him, trailing down his splayed thighs, dripping onto the floor as his holes pulsed from the thorough fucking.
When the thing untwisted its tentacles from his ankles and wrists. he collapsed. He gave a vague thought to the fact that he'd have to clean up the cum where he spilled it on the floor.
When he next caught sight of the creature, it was back to its original form, that strange maw closed, not a seam in sight. It's tongue slipped out to lick over its lip, its nose, up over its eye like a lizard.
He recoiled, turning his face away.
He gathered himself up slowly, hissing when he sat with his bare ass on the concrete.
He dragged himself to the door, monster cum trailing down his legs the whole way there, only to find the door locked. He panicked for a minute, casting a glance over at the thing, which had curled up on the floor like a dog. It let out a little satisfied huff when he looked at it. He shuddered.
He suddenly remembered his keys. He fumbled with his belt, which was still clinging to his waist, though there was nothing else left of his pants except for some tatters at his ankles. He retrieved his keys and got out as quick as he could.
Evan washed in the lab showers. His belly was a little swollen, sticking out minutely, but he put it out of his mind. It was probably just gas or something he ate, he assures himself. He crouched under the lukewarm water and swept his fingers through his cunt, trying to scoop out the cum. It took three times before his fingers came away clean. He gives his ass the same treatment, hissing at how sore and sensitive it was.
He put on a change of clothes, shuddering when fluid leaked from his ass, wetting the seam of his boxers. He went back to the hall to clean the cum he dripped all over the floor, as well as the dirty mop water he spilled when he knocked over the cart. Then he left. There was still more to clean in the stall but he called his supervisor Robin on the phone and told her he had an encounter with one of the animals that they needed to send someone else to finish tonight.
