"Oh, wow," Matti marveled, looking around at what the theater had set up. "They're really going all out, huh?"

She hadn't really known what to expect. In all her time at college, she hadn't made her way to this theater at all. It was small, old, with only one screen, so, usually, if she was going to see something, it would be at the newer one on the other side of town. When she'd heard about this, however, she hadn't been able to resist. She was a sucker for cheesy old horror movies, and that sounded like the perfect way to spend her Halloween, even if she wasn't particularly sure of what the 'spook show' they were advertising it as was.

"Are you regretting not wearing a costume?" Perry asked, his words muffled behind his ridiculous, rubber Frankenstein mask.

"Not even close," she smirked. "I'm willing to pay the extra two bucks."

In reality, though, she was a little disappointed. A lot of the audience members she could see milling around had gotten into the spirit, along with all of her friends. There had been a part of her that wanted to test the theory she'd seen in a lot of diaper stories, that Halloween was the perfect time to embrace your baby style out in public, and call it a costume. She couldn't imagine the her from before she'd found that Sierra doll ever considering dressing as a baby for Halloween, however, and while that might have given it some shock value, it also made her afraid that her friends, or Kelsey, if she'd seen her in the cafeteria today, would have guessed there was something more to it. And that was even without mentioning what had happened at the Halloween party the previous weekend! She definitely hadn't felt up to another costume after that disaster!

So, instead, she'd defaulted to her usual fall look of a nice, big, comfy sweater, almost long enough to hide the whole of the denim shorts she was wearing with it, with one side tucked in so she could avoid being asked if she had anything on underneath, and, of course, her dino hair pin. It was just starting to get cool enough that she knew she'd have to retire the look before long, but she was determined to get at least one more day out of it, even if the show wasn't set to end until midnight, which would probably mean a chilly walk back to campus.

She should be grateful, she supposed, that they weren't being entirely faithful to the concept of the spook show and starting at midnight instead. Other than that, though, she was impressed with how dedicated they were to the theme, decorating the lobby with tons of vintage posters, and even, along one wall, a replica of what looked like a dungeon wall, with two sets of chains and cuffs dangling from it for a photo opportunity.

"Do you want your picture?" Erik teased.

"You know I don't," she rolled her eyes. It did look surprisingly good, especially for something she assumed had been put up for that night only, but she wasn't really a photo opportunity kind of girl. Their school loved to set up those sorts of things, and, on principle, she refused to participate, unless her sister was around to force her to do it 'for the memory', but now and then, she'd see the pictures pop up on Instagram where other people had, and part of her wished she'd gotten one, too.

She did her best not to look at the wall as they passed by it, laden down with their popcorn and snacks, and headed into the theater to pick out the perfect seats. The movie itself wouldn't start for a while, but that was only part of the entertainment. Not long after they had found their spot, the screen crackled to life, but, in keeping with the retro aesthetic, it didn't show any trailers or commercial for anything modern. Instead, it started with a trailer for the movie they were about to see.

"This is so stupid," Matti giggled at the title, the same reaction she'd had when she'd first heard about it, which had led to her having to see it. 'Monsters Invade the Sleepover Party.' It just sounded so silly, she hadn't been able to resist it, and, luckily, her friends had agreed. She'd known as soon as she'd heard it that it definitely wasn't going to be scary, or probably even really meant to be, but she'd resisted looking up any trailers or anything until now.

Seeing it on-screen, it was clear how goofy it truly was. The sets looked cheap, with the dungeon wall outside almost more convincing than the one in the movie, and the 'monsters' promised by the title clearly just a guy in a cheap gorilla suit, while a bunch of girls in colorful, super-short 60s nighties ran around in 'terror.'

"This movie was shot in HorrorVision," the trailer promised. "It is not 3D. You'll be amazed as the movie monsters actually come alive, and invade the theater, looking for new victims, carrying the screaming girls right back into the picture, never to be seen alive again! They might choose you! Girls, don't come alone!"

Matti snorted at that. Beyond the casual sexism of it, though, she had to admire the showmanship. "I bet when they actually showed this for real," she leaved over to Wallace, since he was sitting the closest to her, "they had people come out dressed in their monster costumes. I bet that's why they look so cheap, because they're something that had to go out on tour with the movie. They probably had some plant in the audience that they kidnapped, too."

"What?" Wallace chuckled. "No, I'm pretty sure they're serious, Matti. The monsters really came out of the screen! You'd better be careful, or they're going to come get you!"

"I'm sure," Matti smiled, settling into her seat.

"Don't worry," Wallace assured her. "You're not alone. You have us big, strong men to protect you."

Matti rolled her eyes and stuck her tongue out at him. "I wonder if they're going to do that here? They seem to be really getting into all this." That might be fun, she thought, to really capture the spirit of the whole experience.

Once that trailer was over, another started, for another, more traditional spook show, with hypnotism and live monsters on stage and a live seance, and all kinds of ghosts and ghouls. The trailer itself, of course, promised a bone-chilling experience, one that you would never forget. All of the trailers did, claiming the shows might make you faint, or have a heart attack, or any number of other things, often saying that if you made it all the way through one of them, you'd get a deal on tickets for the next, clearly just a marketing gimmick to get people to come back.

Matti squirmed in her seat, half expecting one of those warnings to promise it would make any girls in the audience wet their pants because it was so scary, not sure she could bear to look at her friends and chuckle at the absurdity, the way they were with the other warnings, if that came up. It seemed so in line with everything else, but, at the same time, it clicked into her new fantasies so hard that she wasn't sure she'd be able to laugh it off without being suspicious.

And, when the trailers promised that nurses would be on hand in case of emergency, her brain couldn't help combining those two fantasies, imagining a whole team of nurses waiting outside the theater with diapers to put whatever poor, fragile girls might have gotten so scared they'd peed their pants into. Would they have had an audience plant for that as well, to run out of the theater and appear later, toddling in with a big, bulky diaper between their legs?

She writhed, nibbling on her bottom lip, thinking about the humiliation of that being her job, of having to pretend, over and over, that she'd wet herself because of some no doubt incredibly low budget, cheesy horror movie, or some people in cheap, old timey monster costumes stomping around on stage. But wouldn't it be even worse if she wasn't a plant, if she'd just had a genuine accident?! And, as insane as it was to recall, she did have some experience in getting diapered by a nurse.

She shook her head, taking a sip of her soda, trying to calm down, to cool off. As easily as that scenario seemed to fit into what was done with these spook shows, it probably hadn't ever happened for real. And it definitely wouldn't have happened to her!

She was still catching herself thinking about it when the trailers ended, followed by a black and white PSA about being afraid, and healthy ways to deal with it, before, finally, the movie itself started, with the director giving another warning about the wonders of HorrorVision, and how any girls by themselves in the audience ought to be careful, or they'd be pulled into the movie.

Everything was just as silly as Matti expected, with the mad scientist, his stereotypical lab coat helpfully labeling him as such with black block letters, and his assistant, Draculina, spouting out exposition about the evil experiments they were going to do, with the gorilla-suited 'monster' in the background, along with various beakers filled with colored liquids, labelled in black letters like the scientist himself. It was all very clunky and obvious, but in a fun way.

And then the sleepover party itself began, a bunch of bubble-headed sorority girls forced to spend the night in the supposedly haunted house for hazing that the mad scientist was using for his scheme. Matti's dirty mind couldn't help looking at the nighties they were all wearing, even shorter than the sweater she was wrapped in, and the little shorts underneath.

If any of them were bedwetters, she mused, it would have been very hard to hide it in those PJs. This really wasn't the right time to be thinking about that, but it was hard not to imagine a bit of a bulge under one of those skimpy skirts, and one of the girls bashfully trying to hide her secret from her future sorority sisters, as they vanished one by one, captured by the gorilla, or Draculina, who was surprisingly tall, and gorgeous in her black, low-cut dress, looking so much more mature than the girls in their colorful little pajamas.

One of the girls was turned into a second gorilla, by mistake, and recruited to help kidnap the rest of her friends, many of whom ended up chained in the dungeon, hands over their heads, like in the photo opportunity outside. That was where Matti's fantasies really kicked into high gear, thinking of the imaginary character being taken away, restrained there, the position making her nightie ride up, exposing her secret for everyone to see, rendering all of her earlier efforts pointless.

She hadn't realized how much of her soda she'd been gulping down until her straw came up empty. By now, the movie was surely almost over, but that gave her an excuse to head out, maybe cool off a little so she could laugh about the movie with her friends on the walk home without feeling too self-conscious about how hot and bothered her fantasy version of it had made her.

"Are you too terrified?" Wallace asked as she got up. "Is it too much for you?"

"Yeah," she rolled her eyes. "That's definitely it." She picked up her cup and gave it a shake to show him why she was really ducking out.

"Be careful," he wiggled his fingers mockingly. "The monsters might get you!"

She smirked, sliding down the row of chairs and past the other patrons, glancing back at the screen now and then, seeing the mad scientist turn his giant ray gun towards the screen, as the gorillas came loping towards the camera. She paused at the aisle, sure this was the moment when the monsters were supposed to come into the audience, chuckling when she saw two people in gorilla outfits appear from behind the screen to raucous applause. That was cool of the theater to do, she thought to herself as she started to head for the door. Maybe she should come here more often.

And then she felt a tap on her shoulder, and she turned around to see one of them standing right behind her. "No," she shook her head. "Sorry, I'm not really into audience participation, I just need... Hey!" She gasped as the gorilla scooped her up, throwing her over its shoulder. "Stop it!" she hissed, kicking her legs, heart pounding at the revelation of how helpless she really was in this position. "Come on, stop it! I'm not the plant, you don't want me!"

But the gorilla didn't stop, carrying her easily down the aisle. It was a bumpy ride, but, to her surprise, she could see another two gorillas out in the crowd, everyone watching them and their antics. Had there been three? Why would the theater have done that, when there were only two in the movie?

"I'm really not in the mood for this!" she told the gorilla grumpily, not wanting to be put center stage, her mind full of images of helpless sleepover party girls in diapers, but that didn't stop her captor from hauling her to the front of the theater, in front of the screen, and then, to her shock, taking a step into it.

Reality warped around her as she passed through it, the sound of the crowd fading away. In front of her, as clear as day, were the mad scientist and Draculina, grinning at her. "W-Wait, what's going on?" Matti whimpered, struggling a little harder.

"Very good!" the scientist praised the gorilla. "Put her on the table so we can begin the experiment!"

"Stop it!" Matti kicked her feet uselessly, pulse racing faster and faster as she saw the table loom closer as the gorilla carried her towards it, until her flopped her down on top of it. Draculina was ready with ropes, tying her down, pinning her into place.

What was going on?! There was no way this was part of what the theater had put together! These people looked exactly like who she'd seen on the screen, and, looking out, there was no sign of the screen she'd passed through! It was just the scientist's lab. She hadn't even been paying enough attention to know what the next experiment he wanted to do was!

"Master, I'm afraid she's wet herself from fright," Draculina purred, running one finger up the crotch of Matti's shorts.

"Wh-What?!" Matti gasped, turning bright red. "N-No, I haven't!" She could feel a warmth there, and a slight wetness, but she knew it wasn't from that, which, in its own way, was almost worse.

"Another one of those, eh?" the scientist sneered down at Matti, struggling futilely against the ropes. "Yes, the transition to our world can be quite horrifying. Deal with her, Draculina. You, bring me another victim."

Matti watched as the gorilla began to walk back in the direction it had brought her from, wanting to see if it would travel to her world again, to see where the seam in reality was, so that, if she could escape, she could hopefully use it herself. Was this a part of the movie? Did they have two plants in the audience? She didn't know enough about the movie to be sure, but it seemed so unlikely that, after all her fantasies, pants-wetting truly would play into this.

"Look at me," Draculina commanded, pinching Matti's chin between her fingers and turning her head. Matti gasped, seeing another part of her imagination come to life, the woman now dressed in a black nurse's outfit, the top cut lower than her former dress, even, the skirt almost high enough to show off her panties underneath. "I know just how to handle girls like you."

She reached below the table, pulling out mass of thick, white cloth, and yellow plastic pants. "N-No!" Matti shook her head. It made sense that they would be cloth. She wasn't sure when disposables were invented, but even if it was before this movie was made, they probably weren't widespread by then.

But that wasn't the issue! How much of this was being shown on the movie screen? Were her friends, and everyone else in the theater, about to see her get diapered?! "Pl-Please, don't!" she begged, biting hard on her lip as Draculina unbuttoned her shorts, sliding them down.

She gave Matti a knowing look when she found the wet spot on her panties, Matti unable to meet her gaze as she pulled them down, too, exposing Matti's bare crotch, still perfectly smooth and hairless from her time at the nurse's office. "See?" Draculina teased. "You're ready for these."

"No, I'm not!" Matti whimpered as the woman slid the stack of diapers underneath her anyway, shocked at how much bulkier they felt than any of the disposable diapers she'd been put into. When she'd been thinking about the bedwetter sleepover party girl, she had never even considered this, but these would have been even harder to hide than what she'd been picturing!

Draculina pulled them up snugly between Matti's thighs, pinning them tightly into place, the extra size and heaviness of them making Matti begin to sweat already, even before the other woman pulled the plastic pants up her legs and tucked them in, sealing in the heat all the more.

"Isn't that better?" Draculina asked with a grin, giving the diaper a pat.

"No!" Matti whined. "I don't need these!"

"Don't you?" Draculina's eyes flashed, and Matti felt her head spinning, making it hard to concentrate on anything for a long moment as Draculina loosened the ropes and sat her up, stripping her out of her sweater.

"Oh!" Mathilda squealed, crossing her arms over her bare chest. "I-I need that! Everyone will see my...!"

She looked down, face burning at the sight of her diaper, the heat only amplifying when she felt a trickle of warmth begin to soak into the cloth as she wiggled in place. "Oh, no!"

"Don't worry," Draculina told her. "All your little friends already saw your first accident, so they know your secret. I'm sure they'll just be grateful you have your diapers on, so you don't make a mess of the dungeon while you all wait your turn to be the scientist's next subject."

Draculina lifted something baby blue and poofy above Mathilda's head, and, reluctantly, Mathilda raised her arms, letting it be pulled over her and into place. When it was done, Draculina helped her off the table, tears filling Mathilda's eyes as she stood there in a blue nightie and a diaper, the former doing almost nothing to hide the latter.

"Wh-What about my shorts?" she gulped.

"I'm afraid you've already ruined those," Draculina informed her, the memory returning with those words, of how she'd wet herself as soon as she'd seen that beastly gorilla, peeking his head in the doorway. Nobody else had seen it, or believed her, so they'd just made fun of her as she sniffled and cried, until both of the monsters appeared and captured them all, one of them dragging her here, to this awful room. She hadn't even wanted to come to this stupid haunted house! She just wanted to get through this so she could join the sorority! "And you've already soiled these as well," Draculina observed, giving the diaper a squeeze, Mathilda blushing and squeaking as she felt another fearful trickle. "Poor baby," the woman mocked. "I'm sure the scientist will come up with something extra fun to do with you, once I tell him about this."

"N-No, please don't!" Mathilda begged as she was dragged through the basement of the house, to the dungeon, where her future sorority sisters were chained up and waiting. She tugged at the hem of her nightie, not daring to look them in the eye, feeling her diaper grow wetter and heavier yet again, sure that, even if they got out of this, they'd never let her into the sorority once they knew her secret.

There was one set of chains open, and Draculina was pulling her towards them, the larger woman far too strong for Mathilda to escape from. She did her best, thrashing and fighting, and, in her wild, pointless struggles, she accidentally did look at one of the other girls.

She frowned, confused. She remembered her, yes, but not from real life. She'd never seen her this clearly, had she? There'd been a layer of grain and grime in front of her, right? She shook her head, the haze of Draculina's hypnosis starting to wear off.

And, in a way, making her all the more self-conscious, recalling once again that she was a part of the movie, too. She groaned, feeling the diaper starting to sag between her legs already, the cloth diapers handling things much differently than the disposables she was more used to, making it far harder to ignore what she'd done in them. Was it obvious from the outside, too? Would these sorority girls know? Would her friends, watching her from the other side of the screen?! And how much had they really seen of her being put into them, and the nightie?! This didn't seem like the kind of movie that would have nudity, but that could have been edited around, and still given everyone a very good view of the proceedings.

Things weren't much better here, in the dungeon, as Draculina closed the metal cuffs around her wrists, which were set high enough in the wall that the petite Matti was almost forced to get on her tiptoes, her nightie pulled high, putting her entire diaper on display, as she whimpered and squirmed.

"Oh," Draculina ran her fingers down Matti's chin. "I see you've broken free. No matter. You won't be going anywhere, my dear. This only makes things more interesting. I may have some fun with you myself before I let the scientist have his turn."

Matti gasped as Draculina gave her damp diaper a squeeze, then turned and sauntered out of the room, closing and locking the heavy, metal door behind her, trapping Matti in there with these helpless sorority girls, as if she were one of them. The most pitiful one of them, the pants-wetter!

"Th-This can't be how the movie ends," she whimpered, tugging at the chains, reinforcing in her mind how hopeless her situation was. "W-We're going to get rescued, right?"

But she had no idea one way or the other. For all she knew, the movie was already over. The closing of the door had certainly had a finality to it, and she could see that being the final shot, but if that was the case, why was she still here?!

She groaned as she felt a twinge, those few trickles doing nothing except teasing her bladder, full of the soda she'd finished off. She squeezed her thighs together, feeling the slick plastic pants between her thighs, and little else, the diaper too big to compress much between her legs, and, to her horror, she felt her body give in, dribbling more urine into the waiting bulk. The dribble turned into a full-on stream as she closed her eyes, praying the cameras, wherever they were, not to mention the sleepover girls all around her, were no longer watching as she soaked her pants.

"Oh, there you are. Did you decide you needed a picture after all?" Erik asked.

Matti gasped, her eyes flying open, looking around her to see the audience filing out, chuckling and talking among themselves. Across the lobby, she could see a clock, telling her it was just after midnight, and, thus, no longer technically Halloween. She glanced up at her hands, seeing that they were still in cuffs, but they were the cheap, plastic ones from the photo op in the lobby. And she was no longer in the nightie, but her old outfit.

"Y-Yeah," she claimed, lowering them, letting out a sigh of relief. It was cut short, however, when she realized not everything had gone back to normal. Her shirt had come untucked a bit, only hanging on by the slightest bit of fabric, but she frantically pulled that free from the waistband of her shorts, letting it fall down over her shorts. Not much of her shorts had been visible, and, as far as she knew, her friends hadn't been there for long, so hopefully they hadn't noticed anything. She could definitely feel the diaper squeezed beneath her shorts, though, so tight that she worried it might burst the button if she wasn't careful. And it was definitely still wet, too, to her chagrin.

"Who were you having take it?" Perry glanced around.

"O-Oh," Matti chuckled anxiously. "Th-They already did, I was just... stretching."

"Cool," Perry nodded. "We're going to go grab some pizza."

Matti fidgeted, feeling the warm diaper around her waist. Did she really want to hang out while she was in this thing?! It would be out of character for her to say no, however, and she didn't feel much better about walking back to campus by herself like this, especially after whatever it was that had happened here tonight. "S-Sounds good," she fibbed, definitely glad she'd gone with the outfit she had, since it would give her a good chance of keeping her diaper hidden.

It didn't do much to hide her waddle, on the other hand. The tightness of her shorts around the diaper might have helped, to some degree, but she was still super nervous as she toddled down the street, hoping that, even if her friends were oblivious, nobody else they passed by would see, and recognize it for what it was. Of course, if they did, she could always claim it was a costume.

"It's too bad you left when you did," Wallace told her as they headed down the sidewalk. "It was the craziest thing! The first girl they, you know, 'pulled into the movie,'" he made air quotes with his hands, "kinda looked like you!"

Matti froze for a moment, her blood running cold. "A little bit," Perry shrugged. "I don't think it was that close."

"I mean, you don't see her face that well," Wallace conceded. "Probably to make it easier for them to find people to use as plants."

"Th-That makes sense," Matti agreed. Of course they wouldn't have thought it was actually her. That would be ridiculous!

"The movie took a real weird turn at the end, too," Erik added. "I definitely didn't see that coming."

"O-Oh, did it?" Matti blushing squirming in her soggy diaper, simultaneously wanting and not wanting to know how much of her exploits the camera had followed. "L-Like what?"

"You wouldn't believe us if we told you," Wallace snorted. "I bet the whole thing is on Youtube. We'll have to look it up when we get to the pizza place."

"S-Sure," Matti nodded. Even if it was on there, there was no way it would have what had happened tonight there, could it? The movie itself had been made such a long time ago, and she'd only gone to see it tonight! If they found it, and the ending was completely different, would her friends get suspicious of what they'd seen? Or would they assume there were multiple endings, for different screenings?

Or was Matti about to see herself, as a member of the sleepover party, getting captured, diapered, and chained up in the dungeon? It was hard to tell, she thought. Even if the clock had struck midnight, it was still Halloween night, and, as evidenced by the bulky diaper she could feel rustling between her legs with every step, that she definitely hadn't been wearing just a few hours before, Halloween was a night where anything could happen.
