The weekend was always a great time to have sleepovers, and this one was no different. Anne and her twin brother Jake were spending the night with their friend Joseph. The kids had been playing together in Joseph's room for the past few hours, but now they were busy transforming his bunk bed into a pillow fort. Anne was up top hanging a sheet down over the front, while the boys were down in the floor stacking up pillows to wall off the remaining openings. Once thing were taking shape, she hopped down and helped them grab some toys and snacks for the fort, but they were all interrupted when Joseph's dad poked his head in the room.

"Hey guys. Having fun in here?" He asked.

"Yeah!" His son replied.

"Heh, alright. Just checking in." He smiled, then turned his attention to the younger foxboy. "Jake, it's almost 8 o'clock, you need to go ahead and put your sleep clothes on."

"Oh." He averted his eyes, "Okay..." It wasn't the sort of thing he liked talking about.

As his father left, Joseph turned to his friend. "Hey, let's get changed in the fort!"

Jake began to crack a smile. After grabbing his bag, he climbed into the bottom bunk with Joseph following right behind him. His sister Anne was the only one who stayed outside. Unlike the boys, it didn't take much for her to get ready for bed. She simply stuck her thumbs in her waistband and slipped her shorts down. Just a shirt and panties was fine enough to sleep in. Meanwhile, in the bed behind her, she kept hearing plastic crinkling and things being taped together. It was the reason her brother was so bashful when talking about his sleepwear. He was a bedwetter, which meant he had to wear diapers at night.

"Okay, my turn!" She heard Joseph say.

The crinkling and taping started up again soon after. Joseph didn't need them, but he always wore them whenever he and Jake spent the night together. She thought it was a little weird, but he insisted it was just because he didn't want Jake to feel bad about being the only one who had to wear them.

Anne continued waiting outside as the boys were still changing. Things got kind of quiet after a while, and it sounded like they were whispering and giggling about something. Getting curious, she looked over her shoulder and raised an eyebrow, "Are you guys done yet?"

"Almost." Jake replied. "Give us a sec, just watch TV or something."

She wasn't sure what they were up to, but she turned back around and continued to wait. There wasn't much on TV that caught her interest, so she kept flipping channels to pass the time. However, as she tried to find a show to watch, something landed on her head. It was some kind of cloth draping down over one of her eyes. She reached up and pulled the item from her face, then held it out to get a better view.

"EWW! Gross!" She screamed. It was a pair of tighty-whities! And worse, they were warm! Laughter suddenly burst from the fort as Anne found another pair of briefs hanging from her shoulder.  She turned around and started to growl, ready to kick the butts these underpants came from. After pulling back the sheet and seeing the boys still giggling, she wound-up her arm and threw their underwear back at them.

"Hey, wait!" Joseph yelped as he shielded himself from the flying underpants. "You can't come in here!"

"Yeah I can!" She fired back, "You guys ain't naked!"

"No, but this a secret club, and we have a dress code."

"Dress code? What?"

"Uh-huh." Joseph started to explain, "Everybody's gotta wear the same thing if they wanna come in. See?" He and Jake hiked up their shirts, showing off their special undergarments.

"Whaaaaaat!?" She protested, "No way! I'm not gonna wear a diaper!"

Joseph shrugged, "Well then you're not getting in. Sorry, but I don't make the rules." Leaning forward, he snatched the edge of the sheet away from her and pulled it shut.

"What!? Yes you do! You just made that one!"

But she got no response. It seemed that boys were ignoring her. She huffed and puffed and growled outside, frustrated to no end that they would shut her out like that. Did they really expect her to put on a diaper? We're they really not going to let her in if she didn't?

Jake and Joseph continued playing in the fort as they keep hearing Anne rummaging around outside. There was a fair amount of grumbling accompanied by the sound of drawers being opened and shut. Soon, the sheet was pulled back once again. Anne stood in the opening, this time with one of her brother's diapers peeking out from under her shirt.

"There, happy?" She mumbled, sounding both annoyed and embarrassed.

The boys stared in disbelief, then started cracking up again. Joseph in particular seemed especially amused, covering his mouth and rolling onto his back. He barely managed to eke out a reply through his laughter, "Haha, okay, you can come in!"

Anne ducked her head and crawled inside. Making her way across the bed, she felt a little apprehensive about having her butt crinkling behind her. However, seeing the boys' padded butts also hanging out eased her concerns a bit. It made her think that maybe Joseph had a point about making Jake feel less bad.

Once she sat down, Jake leaned over and turned his head sideways. He seemed to be taking a keen interest in his sister's diaper. "Your tapes look kinda crooked."

Anne lifted her shirt to take another look. Indeed, they were a bit uneven. Her brother raised his shirt and showed off his taping job as well. His were much cleaner, lining up exactly how they should, keeping everything nice and snug.

"Well I've never put a diaper on myself before." She explained, "It's kind of hard."

Jake giggled, "Want me to fix it? It's a lot easier when someone else does it."

She sighed, but resigned to letting him do it. She laid back and spread her legs so her twin could scoot up between them. As he pushed her shirt up and began pulling off the tapes, Anne finally raised the question: "So why are you guys making me do this anyways?"

"I dunno," Joseph replied, "I thought it'd be fun. Me and Jake wear diapers, so why not you too?"

"But you don't HAVE to wear them! Jake's the only one that pees the bed."

"I told him he doesn't have to do it any more." Jake chimed in as he continued pulling up tapes. "It doesn't bug me as much as it used to."

"I told ya, I really don't mind." Joseph assured him, "I'll keep wearing them as long as you have to."

Jake looked off to the side and sighed, then mumbled to himself, "I wish I knew how much longer that's gonna be..." He focused again on the task at hand, pulling the last of the tapes off of his sister's diaper. As the sides fell flat on the bed, the boys noticed something else that was hidden underneath.

"Hey!" Joseph shouted, "You can't keep your panties on!"

"What?" Anne asked, "Why not?"

"Dress code, remember?"

"So? You can't even tell I have them on."

"Yeah, well me and Jake took our underwear off."

"Uh-huh, I kinda noticed that when you THREW THEM AT ME!"

"Well, you have to take your's off too. Otherwise it's not fair."

"Grrrrr..." Anne growled. "Fine, but you guys have to turn around. No peeking!"

The boys both turned away to give the girl some privacy. Joseph tried to mind his own business, but he couldn't help but get curious as he kept hearing her squirming around behind his back. Slowly turning his head, he looked over his shoulder and tried to sneak a peek.

"JOSEPH!" The foxgirl was laying back on the open diaper, stretching her shirt down while her legs were in the air and her panties were around her ankles.

"Ah! Sorry!" He quickly turned back around as all the blood rushed to his face. He felt bad for letting curiosity get the better of him, but at the same time was somewhat disappointed that he didn't get to see anything.

A few seconds later, Anne finally gave the all-clear. "Okay, you guys can turn back around now." Her panties laid beside her now as she held the front of the diaper over her private region. Her brother climbed between her legs again and continued working on fixing her tapes. While that was happening, Anne looked around and eventually made eye-contact with Joseph, who was sitting by her head with his face still glowing red.

"Sorry again for looking..." He apologized.

Anne grumbled, then folded her arms and turned her head away. She wasn't in the mood to respond. She just laid on the bed silently brooding while her brother finished redoing her tapes. 

"Alright," Jake said, "See how that feels."

She slowly sat up and tugged at her waist. It was definitely more form-fitting, not hanging loose in various places like it was before. But without her panties, the inner padding was even more noticeable. There was no longer anything to separate it from her bare fur.

"This feels so weird..." She blushed, unsure what to think about the whole situation.

"They're not so bad once you get used to them." Her brother replied.

"I think they're kind of comfy." Joseph added, grinning ear-to-ear as he rocked back and forth. "It's like having a pillow under your butt all the time."

The kids settled in for the rest of the night. It took Anne a while to get used to her poofy underpants, but as she and the boys spent the next few hours playing, she almost forgot she was even wearing them.

...

The next morning, the three kids were sound asleep in their fort. The twins laid next to one another at the head of the bed, while Joseph's face was buried in his pillow down on the opposite end. 

But soon, Anne yawned and began to stretch her arms. It was taking a while for her to wake up, but even through the grogginess something didn't feel right. She opened her eyes took a look at her hands. One of them was completely drenched. Wondering how that happened, she looked around until she found a bowl sitting on the nightstand just outside the fort. It was full of water and right next to where she had been sleeping. Did someone put her hand in it?

Not long afterwards, her brother also began to stir. Jake rolled towards his sister and slowly opened his eyes, seeing her sitting up already. "Morning..."

She turned back around and saw him waking up. "Hey."

"Joseph still asleep?" Jake asked after raising his head.

"I think so." She looked down to the opposite end of the bed and saw the catboy's padded rump sticking up in the air. His face was still planted firmly into his pillow.

"Mmm, okay. Well I'll be right back." Now that he was up, Jake pushed away the blanket and sat up on his knees. His butt crinkled as he climbed over his sister and made his way out of the fort.

With him gone, Anne turned her attention to the other boy. She got on all-fours and crawled down to his end of the bed, cringing as she was reminded of her own crinkly behind. "Hey!" she gave him a nudge on the butt, "Wake up!"

"Muh?" He sleepily mumbled as his eyes began to open.

"Did you put my hand in warm water last night?"

Joseph blinked a few times, still waiting for his brain to wake up. But once he could finally process her question, a devilish grin spread across his face. "Well, did it work?"

"You butthole!" She shoved him. "What'd you try to make me wet the bed for!?"

He began to laugh, "I dunno, I thought it'd be funny. Besides, you got a diaper on."

"Yeah, 'cause you made me wear it! Was that your plan all along?"

"No... I mean, I was just teasing at first, I didn't think you'd really put one on. But then when you did, I got an idea. I wanted to see if the hand-in-warm-water trick actually works." Joseph smirked again, "And you never answered my question: Did it?"

Anne's face turned blood red, "Do I look wet to you!?" She lifted her shirt and showed off her diaper. It was as dry as when she put it on.

"Aw, darn." He continued to chuckle, but sounded more disappointed. "I wanted to see you wet your diaper."

"Grrr... I ought to tickle you until YOU wet YOUR diaper!"

His mocking laughter became more nervous, "Haha... N-no, don't..." He started to blush. "I'll get in trouble."

As things started to calm down, Jake pulled open the sheet and crawled back inside. He picked a spot behind his sister, flipped around and sat down. "Ah, that's better."

Anne turned and looked at him, then back at Joseph. "So is the dress code over now? Jake's not wearing a diaper any more."

"Hee-hee!" The foxboy grinned and wiggled his feet, "Kinda funny being the only one." Indeed, he was back to wearing his tighty-whities.

"Hmm, yeah..." Joseph sounded defeated, "We gotta take the fort down anyways."

"Alright, well I'm gonna go change." She pushed the sheet out of the way and scooted out of the fort. After she picked her panties up off the floor, she headed to the bathroom to go put them back on.

While she was gone, the boys began to disassemble the fort. They took down the sheet that was hanging from the top bunk and threw some of the pillows back up to the top bunk. Anne returned soon afterward and helped with cleaning up the floor and getting everything straightened up. The sleepover was coming to an end and the twins would have to head back home soon. Still, they all had a lot of fun with their secret club. They would have to do it again sometime, though perhaps without such a strict dress code.
