A "Haww"fect Costume

"Hmm... What about this one, honey?" Larissa, a 25-year-old, slim, black-haired girl asked her tall, blonde boyfriend, showing him two cat costumes; a male and a female. He scrunched up his nose. "We were cats two years ago, hon. We can't go as cats again... What about dogs?" "No, Peter, you know I don't like dogs." Larissa sighed and looked at more costumes. They were busy picking their couple costumes for this years' big Halloween party, but they were coming up short with ideas, even though they'd wandered into the town's biggest costume shop with rows upon rows of costumes. Nothing caught their fancy, not even after spending an hour in there.

The shopkeeper, an elderly woman, clears her throat. "Anything special you're looking for, dear? You've been in here for an awfully long while." "Ah, yeah... We just can't seem to find anything that's perfect for us," Larissa answered her with a sigh. "Oh? What kind of costume are you two looking for, then?" "A two-man costume would be nice," Peter told her. "But it needs to be special, too." "A special two-man costume? I think I've got just the right thing for you two," the woman answered with a smile. "You do?" Larissa asked; eyes wide as saucers at the prospect of finally getting a costume that was just right for the both of them. "I do. This." The elderly woman pulled out a big, brown package from underneath her table. "What is it?" Peter asked, just as intrigued as his girlfriend. "It is a donkey suit. Now, I know donkeys might not be that special, but trust me, with the details in this costume, you two will be the life of the party!" she promised them with a broad smile. Larissa and Peter looked at each other, doubt in their eyes, but eventually, they wound up buying it. Time was too short to find another alternative.

They got back home with the costume just half an hour before the party was to start, and so they got down to business pretty soon. Looking at the instructions, it said to strip naked before entering the suit, or at least to only wear underwear. Well, guess it made sense; with two persons in there, it would be pretty darn hot. So they both stripped to their underwear, then grabbed their respective parts of the costume - Peter had the front legs, neck and head, while Larissa had the hind legs, ass and tail.

With help from Larissa, Peter squished his head and torso into the head and neck of the donkey, before slipping his legs into the front legs of the suit. The fit was tight, but not uncomfortable. "I'll join you in a sec, babe," Larissa grinned, slipping her legs into the hind legs of the costume, before she stepped right up to him, and zipped the two parts together, her torso making it for the donkey's torso, her hands on his hips. "This is working out great, huh?" she grinned. "Yeah, it's a little tight, but it works!" Peter grinned, looking at them in the full-length mirror, through the mouth of the donkey.

But as Peter was admiring how realistic the suit looked, Larissa started to feel... Strange. She suddenly couldn't feel her feet, they went completely numb. As dark as it was inside the suit, she couldn't see what was going on, but she guessed it was just because of her odd position, making less blood flow to her feet. What she didn't know, was that the suit was changing her. Her toes merged into one big lump, bones to one thick, solid cannon bone, and then - her nails darkened, widened, black keratin soon covering her entire foot - her foot had merged, transformed into the suit's hoof, and her other foot soon did the same, leaving her with two hooves instead.

But when Peter feels his own feet go numb, he senses something is amiss. "Hey, honey... Are your feet numb, too?" he asked, slightly shakily. "W-what? I thought it was just me!" she told him, before she felt her ankles stretch, bones and muscles lengthening to fill out the costume's legs. "Oh shit! Peter, something's really, really wrong with my legs!!" "What? What's happening?" "I dunno!!" she told him with a panicked voice, as the costume wraps around her thighs as well, causing them to shorten and thicken - changing into the flanks of an equine. "Oh shit! Oh shit! Peter, we need to get out of this suit, now!!" she cried, fumbling around for the inside zipper. But where the zipper had been just minutes ago, there was... Nothing. Just more of the fake fur fabric, which felt more and more organic by the second... All... Warm... Squishy...

"Then zip it up!! Now!!" Peter ordered, feeling his feet lengthen like hers had just moments before. "I can't! The zipper's gone!" she sobbed, trying to push against him to see if the suit would give with enough stretch. "Ah!" Peter cried out as the weird feeling travelled up to his knees and thighs, the suit wrapping around both his legs. His thighs, like hers, shortened, while his knees gave two sickening crunches as they reversed, now functioning as the donkey's elbows instead of knees. Larissa is still crying as she desperately pushes against Peter, but the suit doesn't budge, not even an inch. In response, the suit worked harder, faster, to change them, and Larissa was dumbstruck with the next change.

She looked in disbelief as her hands flowed into Peter's hips, his skin growing over her fingers, then her entire hand, as she lost all sensation in it. She couldn't even scream, she was frozen in terror as her hands merged right into his hips and vanished, leaving no trace that they had ever even existed, her bones and flesh simply melting away into his. Peter feels this, it feels like she's still holding his hips, but the sensation has changed, it feels less... Defined. "Honey? What's wrong?" he noticed her quietness, and reached around to touch her - only, he found her couldn't. His arms responded, but it felt like something was keeping them tightly to his side, other than just the tight suit around him. Looking down, he screamed.

What he saw, was similar to what Larissa had just seen - a thin film of his own skin, almost like latex, bound his arms to his sides from the shoulders and down. And as he watched, he was his torso absorb the flesh and bones of his arms, felt it, the bones melting away into flesh, his nails disappearing as his hands vanished inside him before the rest of his arms followed suit, leaving him armless in less than two minutes, only smooth skin remaining on his shoulders, not leaving a single trace that he had ever had arms to begin with. As he is busy panicking over the loss of his arms, Larissa curses her body for starting to take pleasure in the changes. Against her will, her pussy was dripping wetness down her thighs, into the suit. The suit seemed to almost feel that, some of the fabric brushing against her nether lips.

When she felt the smooth, almost organic material brushing against her, she suddenly found her voice again, crying out with the sharp sting of pleasure. She didn't want to like it, but her body did, and her mind was fighting a lost battle as the suit tightened up against her skin, flush with her ass, the material bonding to her skin with a weird, tingling sensation, before she felt warmth surging into her ass. She moaned as her buttocks filled with warmth; slowly inflating with flesh, with muscle, with tissue, to fill out the donkey's giant ass. She bit her lip as her ass grew to its new proportions, then gasped as the suit contorted and dove into her ass, stretching out her asshole, pulling, forming it into a proper, large donkey's pucker. She moaned as she felt the material wriggle about her bowels like a snake, slowly changing her from the inside as well.

"Oh shit... Oh shit..." Peter whimpered, feeling his torso slimming out and lengthening, pushing his head properly into the head of the suit as the suit bonded with his chest. he found it difficult to breathe, suddenly; his organs slowly withering away to be replaced by the large animal's windpipe and esophagus, his ribs melting away as his spine now functioned as the horse's neck. At the same time, Larissa's moans increase in volume and frequency, as she feels her torso stretch out, too - as it does so, she is pushed further into Peter, and like her hands before, the rest of her arms merges with him and vanishes as well, just as his hips are changing into the donkey's shoulders with obnoxious crunching.

Peter gives a final gasp as he feels the mask of the suit attach to his nose, pulling at it. He watches in sick fascination as his upper jaw extends to the suit's demands, his lower jaw soon following. He groans, then lets out a loud 'HEE-HAW!' as his face is stretched into its final appearance, his larynx changing his voice to the deep tone of a male donkey, as his ears moved to the top of his head, stretching to fill the ears of the suit. As he opened his eyes again, white bled into animalistic brown, no human features left on him.

"Oh no... No, please no..." Larissa is crying, trying to stretch her head and neck away from the inevitable - but as her torso keeps lengthening, she doesn't have anywhere to run to, and her cheek touches Peter's ass. Instantly, she can feel the skin sticking, merging, feeling as warm as if she had superglue on her cheek tying them together. But the reality was much, much worse, and her sobs were silenced as her mouth fused with his crack, sealing shut and rendering her unable to make a sound. She accepted her fate as she felt the same happening to her nose, wishing this would all be over soon... Yet, despite being unable to breathe, she was fine, even as her face continued to disappear into his crack. Her consciousness faded away, and only a minute later, her shoulders were fused to him, her collarbone merging with his to become bigger, stronger, her hips cracking loudly and painfully into quadrupedal alignment.

The last thing she feels before she slips away forever is a tingling in her loins, and the need to push. She pushed, and pushed, and if she could, she would've cried as she felt two orange-sized orbs fall out her cunt inside a sack of skin; the skin merging with her pussy, sealing it shut - before the brand new testicles descended into the suit's furry pouch, the fake donkey dick hiding in there fusing with her pubic mound.

Larissa's consciousness gone, and Peter's taken over by the suit; the new, horny male donkey let out a loud 'HEE-HAWW!' as it looked around. Finding nobody in sight, it worked its way out of the apartment building, onwards to find a new mate...
