Chapter Text

An ordinary looking street on a cloudy autumn day. No people around, until a dazzling flash of blueish light resolved itself into a dazzlingly beautiful blonde woman in her twenties wearing black jeans, a blue leather jacket and a determined expression, causing a few leaves to twirl and dance briefly. She pulled a mobile phone out of her trouser pocket.

"How long have I got in this one?" said Rose.

"Three days and eighteen hours." replied the older male voice on the other side.

Rose put it away, started walking. It's a residential area, houses and trees with the occasional parked car.

"I'm bursting." thought Rose. "I should have gone to the loo before shifting."

Rose kept walking, hoping she would find a public toilet. Eventually she came to a roundabout, surrounded by a restaurant, a petrol station and a hotel called the Pamper Inn, which had a purple logo that looked like a pillow with a smiling face.

"I'll need a place to stay." thought Rose, heading inside.

Rose approached the front desk. A young man wearing a hotel uniform sat behind it.

"Scuse me, do you have any rooms available? Today?"

"We do have a few left."

"How much?"

"Is it just yourself staying here?"

"Yeah."

"£105"

"Is it okay if I pay cash?"

"No problem at all."

Rose unzipped a pocket in her jacket, pulled out an alarming amount of £20 notes, and counted off six of them. Hesitates.

"Does this money look totally normal to you?" asked Rose, waving the six notes in his face.

He peered at them quizzically, then smiled. "It does." he answered. She handed him the six notes.

"Here's your change." he says, handing her a £10 note and a £5 note.

"And here's your room key." he says, handing her a card with 223 on it.

"Thanks." says Rose, heading off towards her room.

Rose entered the room and immediately opened the bathroom door. There was a sink, a mirror, a combined bath/shower, a towel rack and a small bin, but something was missing. Something very important.

There was no toilet.

Rose stood there shocked. Do toilets not exist in this universe? Do they pop pills that make their needs go away, like in the future? She had taken one once, and it made her feel uneasy wondering where her wee went. She could really use one of those pills right now, though. The pressure in her bladder was enough that she considered taking her pants and trousers off, climbing in the bathtub, standing there and pissing. That would get piss all over her legs, her feet and the bathtub that would need to be rinsed off with cold water from the shower head and dried with a towel.

"I am not doing that." decided Rose, and she marched off back downstairs.

"There's a problem with my room." said Rose, almost before she reached the front desk.

"We apologize. What is it?"

"There's no toilet. In the bathroom."

"There's no what in the bathroom?"

"You don't have toilets?"

"I don't know what that is, sorry. If you tell me how to spell it, maybe we could put some of them in there for you."

Rose was left speechless for a few moments.

"I really need a wee." she said simply.

"So why don't you wee ...?"

"Where??"

"In your nappy ...??"

"I don't have a nappy." replied Rose.

"Oh why didn't you say so, they're free. Here you go." he said, offering Rose a nappy that she could almost swear came from out of thin air.

Rose grabbed it off him. "Thanks."

Rose went back to her room, closed the door and looked hesitantly at the nappy. It was covered in little versions of the hotel's purple logo. On the front side, there was also a long empty purple thing with rounded ends.

"Go on, Rose. There are no toilets, so it's either that or you find a lamppost." said a Northern male voice in Rose's head. That was what the Doctor told her to convince her to take the pill all that time ago, and it was as true now as it was then.

Rose quickly took her trousers and pants off and tried to put it on. "How do I join up the sides?" she thought, too desperate for her brain to function. "Ohhh, I need to pull the bits of plastic off the tape."

Rose taped herself in, and just in time. There was a whooshing, trickling sound as she flooded the nappy. She looked down after she finished. Now the bottom third of the purple thing was yellow.

"That must be the wetness indicator." thought Rose. "Least it's not full, I'd hate to ask for another one right away."

Rose put her black trousers on over the nappy, only just managing to zip and button them up. She left her pants on the floor.

Rose picked up the remote on the table, switched on the TV. The news came on. She watched it for a while, hoping to see something that could help her find the Doctor, like an alien spaceship crash. If this universe had a Doctor, he or she would be there. The news was much more boring than that, unfortunately. It was a long shot anyway, as only one universe seemed to have a Doctor, which was mysterious of him since most people seemed to be in most universes.

"It's already dinner time." thought Rose, noticing the time in the corner of the screen. Darkness had fallen fast. She left her room and headed to the restaurant across the road called the Cattle Consumer, which had a logo that looked like a baby cow's face.

Looking around, Rose observed there were no toilets in the restaurant, and people tended to wear loose trousers that bulged unmistakably if you looked closely enough. "They're all wearing nappies." she thought.

Rose ordered a beef burger with a side of beef ribs. Then she ordered a huge salad to apologize to her health for all the bovine-based food. Finally, she ordered a chocolate fudge cake for dessert to apologize to her taste buds for scoffing the entire salad.

A while later, Rose was back in her hotel room and a familiar feeling filled her with a sense of dread.

She needed a poo.

"Can't believe I'm about to do this." thought Rose.

Rose's body took a bit of convincing, but eventually it relaxed and let her empty her bowels into the nappy.

"I shouldn't sit here in a pooey nappy." thought Rose. She got up off the bed. "I need to change myself. I've never changed a nappy before, but I can work it out."

Rose opened cupboards, looking for a fresh nappy, but found only pillows and sheets.

"I'll need to go down and get another one. He's got a pile of them under his desk, apparently. Wait, won't I also need wipes and powder and things?"

Rose looked around for wipes and powder and things. On the main table there was only long stick-shaped bags of milk and other little oddities. In the bathroom there was only a deodorant, a toothbrush and a tub of toothpaste. Shouldn't such a nappy-centric society have these things laying about? Was she not supposed to change her own nappy?

"Just go down to the desk and say your nappy needs changing." Rose said to herself. "You can tell from their reaction what you're supposed to do."

Rose stood in front of the desk once again and did just that. "I need... a nappy change." she said, trying to mentally disassociate herself from the embarrassment of such a statement.

"We offer changes for £14.99" said the man behind the desk.

Rose immediately unzipped her jacket pocket and practically threw the £10 and £5 notes at the man. Whatever would get this soiled nappy off her as soon as possible.

"Great, I'll send someone up."

Rose returned to her room. Only a few minutes later, someone knocked on the door. She opened it, and a young woman was standing there, average looking, slightly shy, dark hair in a ponytail, wearing the hotel uniform and holding a bag.

"Did you request a change?" she asked.

"That's me." said Rose.

The woman stepped into the room.

"Lay on the bed then."

Rose got on the bed.

"Pop your trousers off for me."

She was using a customer service voice, but she was speaking to Rose like she was an adult, like this was the most normal thing in the world.

Rose undid her trousers, flung them on the floor and laid there with her legs apart.

The woman opened her bag, which had a clean nappy, cotton balls, hand sanitizer, rash cream and wet wipes in it. She sanitized her hands, ripped open Rose's nappy, rolled it up with the solid waste inside, wiped Rose clean from front to back, disposed of the used nappy and wipes in the big bin in the corner of the room, put a new hotel branded nappy on Rose and taped it up perfectly. She did it quickly, all without saying anything or looking Rose in the eyes.

"All done, miss." she said, looking at Rose again and giving her an awkward smile.

"Thanks." said Rose. The woman left.

"No one needs to know about what just happened." thought Rose. "Not the Doctor, not anyone at Control, none of them will ever know."

Rose got up but didn't bother trying to put her trousers back on. She was feeling a little warm and stuffy in the hotel room. She opened the window but it didn't open very much.

Rose stripped off her jacket and top, revealing the travel disc around her neck, hidden under her clothes. She took it off and placed it carefully on the small bedside table. It looked like a child's toy, but it was very important. Without it she would be stuck in this place forever. She took off her bra, leaving her naked except the nappy.

Rose flopped onto the bed and got under the covers. After a minute she felt too warm again so she flipped over the duvet and now she was under the cool side, chilled by the fresh air from outside. She fell asleep immediately.

Chapter Text

The next morning, like every other morning, Rose woke up needing a wee. She wanted nothing more than to stay in bed, but the urge to wee was too much. She was about to drag herself out of bed when she remembered.

"Oh yeah." thought Rose, with a big smile. "Maybe this isn't so bad after all." There was a whooshing sound under the covers.

An hour and fifteen minutes later, Rose got out of bed for real. She went into the bathroom and unscrewed the lid on the tub of toothpaste. While brushing her teeth, she noticed something. One of the smooth white panels of the bathroom wall was slightly raised. She tugged at it with her fingers, and it opened to reveal a huge cupboard, containing wet wipes, hand sanitizer, rash cream, cotton balls and a stack of clean nappies. The exact same items as the woman's bag.

Rose suddenly felt stupid. Of course these people change their own nappies. How was she supposed to know all this stuff was here, though? The door didn't even have a handle.

"This is good. Now I can change my own nappies." thought Rose with a new wave of confidence. "I already learned everything from watching her."

Rose wondered why they change people's nappies for them. "Maybe they don't want to face the mess. They just want to relax, have a break." she guessed. Personally, she preferred to change her own nappies because that option didn't involve strangers staring at her privates.

Rose realized she had her arms crossed tightly around her chest. It was too chilly now. She really fancied a warm shower, but how would that work with the nappy? Are they waterproof? She wasn't sure.

"I can just take it off and put it on again." she realized.

Rose carefully undid the tape and left the nappy on the floor outside the bathroom.

After showering and drying off, Rose picked up and looked at the nappy.

"Eurgh, this one's been pissed in." thought Rose. "By me." she added. "I could just put a fresh one on."

There was more than enough of them in the cupboard to last her entire stay even if she used one for every wee.

That would be wasteful, however. Rose had seen so many environmental disasters in different realities that her habits had changed forever.

Rose stroked the inside of the front. They were so absorbent it felt totally dry, just a little heavier. She put her nappy back on, got dressed and went down for breakfast. Before she went, she picked the pants up off the floor and stuffed them in her pocket, just in case. She didn't want to go too native just yet.

Breakfast was free for hotel guests. Rose had a glass of juice, a bowl of granola cereal, two sausages, two fried eggs, a slice of buttered toast followed by one more slice of buttered toast followed by another slice of buttered toast, a cup of coffee, a banana, a satsuma, a yoghurt and a bran muffin. Her mission across the multiverse required proper sustenance.

When Rose couldn't possibly eat any more, she refocused her mind on what she came here to do. Finding the Doctor, or someone who could help find the Doctor.

A man at a nearby table was using a laptop. Rose slid up to him.

"Scuse me. Can I borrow your laptop for just five minutes? I need to look something up, it's really important."

Rose fluttered her eyelashes at him in case that helped.

"Alright, but only five minutes. I'm watching you."

"Thank you so much." Rose said sweetly as she aggressively grabbed the laptop and got to work.

Rose typed "doctor blue box" into a website called Powda, which seemed to be these people's equivalent of search-wise.net or Cybask, but found nothing Doctor or TARDIS related. She typed "clive finch", but he didn't appear to exist. She typed "rose tyler", and a bunch of links to profiles on various websites popped up. With pictures of her own face on them.

Rose clicked on each of them. One of them had an address on it. She hit the Maps button on the laptop and typed it in. A map from her current location to the address came up. She pulled out a pen and copied the map onto a napkin.

"Didn't even need five minutes." said Rose, pushing the laptop back to him.

A little while later, Rose was walking along clutching a napkin, when she stopped at a block of flats, went inside and climbed up the stairwell. She walked down the corridor, looking at the doors. "Flat 34. This is it." she said to herself.

Rose pushed the doorbell, stood there nervously. After a minute, it opened.

"Oh my god." said the Rose who just opened the door, wearing a stripy top and grey pyjama bottoms with the clearly visible top of a nappy sticking out. "Are you, like, my identical twin sister or something?"

"I'm you."

"From the future? I'd say about five years."

From another universe."

"Don't be daft. There's only one universe."

"There's more universes than you can possibly imagine, and every single universe is in danger."

"From what?"

"We don't know. That's why we're trying to find someone who does."

"If you're really from another universe, then prove it."

Rose took out her mobile phone, pressed a button.

"Control, I need you to put mum on."

Silence for a few moments. Rose held the phone out to Other Rose.

"It's for you."

Other Rose leaned towards it.

"Hello?" said an older female voice on the phone.

"Mum? Is that you?"

"Course it's me."

"You're alive."

Rose ended the call. "Your mum isn't alive?"

"No."

"What about your dad?"

"My dad died when I was a baby, and I lost my mum a couple years back. She used to live with me in this flat, now there's just me."

"I'm so sorry." said Rose, hugging her other self.

"How long are you in this universe for?"

"A few days."

"Where are you staying?"

"A hotel."

"You can stay with me, if you like. I've got a spare bedroom."

"Thanks, I will." said Rose, squeezing past her other self to get inside.

In the living room, Rose was sitting on the couch and Other Rose was walking about.

"Sure I can't get you something?" said Other Rose.

"Yes, I'm full. Tell me, do you know a Doctor that travels in a blue box?"

"No. I've always been healthy, and the doctors we have here sort of... stay in one place and we go to them."

Rose slumped down further on her new best friend's couch, defeated.

Other Rose is about to leave when Rose sits up suddenly.

"Can I use your --" said Rose before cutting herself off.

"Use my what?"

"Never mind." said Rose.

"Alright then." said Other Rose before leaving Rose laying on the couch.

Rose needed a poo, properly. She felt like she was about to explode, and she knew what she had to do. There weren't exactly any other options.

"Never getting used to this." thought Rose as she filled her nappy with poo while laying on the couch. It was easier the second time, though.

Other Rose came back a minute later with a bowl of strangely shaped snacks and a can of beer for herself and tried to move Rose out the way so she could sit down.

"Budge up, the game's about to start."

Rose moved over.

"Where do you keep your nappies?" asked Rose.

"Do you need a change? I'll change ya."

"I can do it myself. It's... fine."

"No no no. Don't talk nonsense. You're my guest, I insist."

Not wanting to be considered rude, Rose gave in. Other Rose got up, came back with a bag like the one the hotel woman had and stood giving a look.

Rose sighed and pulled down her trousers to her ankles. Technically, this wasn't a stranger.

Other Rose went about changing Rose's nappy the exact same way as the woman in the hotel did. Except she wasn't so quiet.

"Blimey, that is a lot. Least it doesn't stink like some people's. Look at that 70s bush, you really are me. I had one, but my girlfriend wanted me to wax it, so I don't have one any more." Other Rose grinned. "A girlfriend, that is."

Rose started to long for nappy changers that don't make highly personal comments in her own voice.

The fresh nappy Other Rose put on Rose had pink cartoon footballs all over it, and a logo she couldn't read because to her it was upside down.

"They do it fast here, like Formula One." thought Rose. She didn't want to admit it, but the big breakfast, big poo and feeling of the soft nappy on her clean bum had made her feel amazing.

"This is really weird for me." said Rose after putting her trousers back on.

"It's really weird for me too." said Other Rose.

"No, I mean the whole nappy thing."

"What nappy thing?"

"Where I'm from, we don't wear nappies."

"Do you just wee and poo all over the place? Remind me never to visit there."

"No, we have these things called toilets."

"Called what?"

"Toilets. When we need to wee or poo, we go to the toilet and sit on it."

"I don't wanna know." said Other Rose, closing her eyes and putting her hand up in the air.

"Alright then." said Rose.

"I feel sorry for you now."

"You feel sorry for me? Why?"

"Having to live in a universe where the nappy was never invented."

"We do have nappies! Nappies are for babies where I come from. You're all just... babies."

"Babies? Why doesn't everyone wear them?"

"S'pose it would be too much fuss, changing nappies all the time."

"It's not too much fuss going to these toilet things all the time?"

"We manage."

"What happens if you feel a need and there isn't a toilet nearby?"

"We hold it until we find a toilet."

"What if you don't find a toilet soon enough? Won't there be, ya know, a mess?"

"That does happen sometimes, but we clean it up."

Other Rose laughed. "Has that ever happened to you?"

"Only once. It was on a planet called--"

Loud cheers came from the television.

"I missed a goal. Please be Brookton." pleaded Other Rose tearfully.

The "BRK 0 - 0 WF" on the screen changed to "BRK 1 - 0 WF".

"Yes!" screamed Other Rose. "Yes! Yes!" She shoved a massive handful of snacks into her mouth and took a huge gulp of beer.

The football players were men, and so were most of the fans celebrating.

"Those football players... are they wearing nappies?" asked Rose.

"Course they are."

"Doesn't something big and bulky like that get in the way of playing?"

"They have sports nappies. Lighter but less capacity. Refastenable sides for easy changes at halftime."

The game ended, and Other Rose was ecstatic because Brookton had defeated Westfield 3-0.

"I've gotta get ready for work." said Other Rose, getting off the couch.

"It's the afternoon."

"I get Wednesday mornings off."

Rose remembered how she used to get Monday mornings off back when she worked in the shop.

Other Rose started changing her clothes. Rose squinted at her nappy, trying to read the pink word among the pink footballs.

"Oi, don't look!" said Other Rose. Rose said nothing.

Other Rose changed into a red jacket and jeans and headed for the door.

"Wait, before you go, which bedroom is mine?"

"That one there." Other Rose pointed as she left.

Rose took out her mobile phone, ready to tell Control there was no sign of the Doctor so they could cannon her out. Her finger hovered over the button. She'd met plenty of Petes and Jackies, but never another version of herself. Maybe she never would again. She put the phone away. A couple more days wouldn't hurt.

Rose changed the TV from the boring football channel to another channel with reality and entertainment shows. They appeared totally normal except for the ad break containing an ad for a nappy brand clearly aimed at adults. These didn't have baby-related things like teddy bears and ABC blocks on them. They emphasized qualities like absorbency while presenting them as for cool, quirky and sexy people.

Rose's phone rang during dinner that evening.

"Oh no that wasn't me, that was Nappy Rose." said Rose into the phone.

"What did you call me?" said Other Rose after the call was over.

"Oh I just called you Nappy Rose because you're, ya know, from Nappy World."

"I'm gonna call you Toilet Rose because you're from toilet world."

"Please don't call me Toilet Rose."

"Well don't call me Nappy Rose then."

That night, Rose went in her room and looked around. It reminded her of her mum's old room. She got ready for bed by getting naked except for her nappy. She put her travel disc and the pants she arrived in safe in one of the drawers. "The only pair of knickers in the world." she thought.

Chapter Text

The first morning at Other Rose's, Rose woke up and wet her nappy. Whoosh. She flung off the covers and got out of bed. She found Other Rose had gone to work already. "I went to sleep first, why didn't I wake up first?" she asked herself. "Must have been tired from all that walking."

Rose went into the bathroom and brushed her teeth. "This place could do with a bit of cleaning." she thought, but it wasn't bad enough that she actually cleaned it. She took her nappy off to get ready to shower. She was about to leave it on the floor when she noticed the indicator was full. She had used it once while watching TV, once during dinner and her morning wee had filled it up. She binned it.

After her shower, Rose managed to find the hidden compartment with the nappies in it, several giant stacks still in their packaging and one ripped open with half the nappies gone. She reached in and pulled one out. On the front, just under the waistband, it said "FOOTYGIRLZ" in big pink letters with a vaguely graffiti-style font. She put it on.

"One trip to the bathroom instead of three." thought Rose. "I suppose no one's way of doing things is better. Just different."

In the living room, Rose noticed a note was stuck right on the middle of the television screen. She took it and her own handwriting stared back at her.

"You're s'posed to change 'em when this thing gets full, by the way. Don't want you leaking all over my couch." with a drawing of a wetness indicator.

Yes, the words "s'posed" and "'em" were spelled exactly like that, with the apostrophes.

"I guessed that already." thought Rose, annoyed.

While Rose was watching TV, a character on the show she was watching mentioned that they needed to go change themselves.

"Next time I poo, I'm going to change myself." Rose vowed to herself. She somehow felt like this would allow her to recover some of her dignity.

"Sounds mad, but I hope I have to poo again before I shift out of here. I'd be mortified if I only got changed by other people the whole time. Changing my own pissy nappies doesn't count."

The thought made Rose feel like a baby, even though she knew nappies had nothing to do with babies in this version of reality, except of course for baby nappies, which were nappies designed specifically for babies.

When Other Rose got home, Rose was already cooking dinner.

"Oh you're back. I got hungry so I thought I'd cook dinner for both of us. We eat the same food anyway."

"It's like having a wife. I'm gonna miss ya when you've gone."

"You were going to say toilet." Other Rose announced unexpectedly after she and Rose sat down to eat dinner.

"What?"

"The day you arrived, you were like (doing a stupid voice) "can I use your" and right after you needed changing. You wanted to use my toilet, didn't you? You forgot we don't have them."

"I did, actually."

"It's totally normal over there for people to sit on each other's toilets?"

"I mean, yeah."

Other Rose pulled a disgusted face and continued eating.

"Eurgh. We don't use each other's nappies. Not unless it's an emergency."

"It's not a big deal."

"You don't care that it's full of someone else's..."

"It's not full of anything. We flush it with water after each use."

"Isn't that wasteful? Using all that water."

"What about all the fabric used to make all these nappies?"

"Never thought about it like that. Maybe you people have a point."

Chapter Text

The second morning at Other Rose's, Rose was awoken by a whooshing sound. She realized that she had started wetting her nappy before she even woke up. This alarmed her. "If I spend too much time here I might wet the bed my first night back in normal reality." She had never wet the bed.

After Friday night dinner, Other Rose tried to persuade Rose to go to the pub with her, and eventually succeeded.

The pub was called the Pot & Train, with a cooking pot and old fashioned train. Not long after they arrived, a very pretty plus size Asian girl walked in and went right up to Other Rose.

"Rose Tyler!" she said in an American accent.

"Bunny Yang! Not you again." said Other Rose.

Bunny and Other Rose hugged. Bunny was wearing jingly golden earrings that were shaped like half of the zen symbol or whatever it was called, Rose wasn't sure.

"How've you been? More importantly, where've you been?" asked Other Rose.

"I've been somewhere." said Bunny. "You are looking good. Hey, you never told me you were an identical twin." said Bunny, pointing at Rose.

"We never did much talking." said Other Rose.

"Cheeky! You still with Vicky?"

"Nooo. I'm single. You still with that Patrice boy?"

"I'm single too. You have got to let me buy you a drink."

"Okay."

"You've just got to."

"I said okay."

"Please, I'm begging you."

"And I'm saying okay." said Other Rose, grinning widely.

Bunny turned to the bartender. "I'll have a raspberry vodka and coke, and this gorgeous girl right here will have a pint." she said, putting her arm around Other Rose.

"You know me so well." said Other Rose.

Other Rose and Bunny seemed to be in a competition for who could giggle the most. Rose rolled her eyes as far as they could go - and saw something on the other side of the pub that shocked her to the core.

A group of four men were sat at a table, and one of them was the Doctor. He was wearing a check shirt instead of his usual outfit but it was definitely him. The Doctor who said goodbye to Rose that day on Bad Wolf Bay.

Rose ran up to them. "Doctor??" she said, staring right at him.

"I'm not a doctor." said the Doctor in a Scottish accent. The other men laughed a little.

"Sorry. Sorry, I thought you were... someone else. My name's Rose."

"I'm Billy. Billy McFarlane." said the man who looked just like the Doctor.

"Rose Tyler. Nice meeting you, Billy." said Rose, turning away again.

Rose headed back to the bar, and saw her other self and the chubby cutie kissing passionately. She turned around, went back to Billy.

"Actually, could I buy you a drink?" said Rose.

The men all stared at her.

"Sure." said Billy.

"Oooooh!" mocked the other men at the table in unison.

"What are you having?" asked Rose.

"Double whisky with apple juice." said Billy.

Rose went up to the bar.

"A glass of white wine and a double whisky with apple juice please."

"Will that be cash or card?"

"Cash." said Rose.

Rose and Billy sat and talked for ages. She had several glasses of white wine while he sipped his whisky. Apart from his strong arms and stubbly beard, he didn't just look like the Doctor, he was absolutely identical. His life story seemed convincingly human though.

Rose remembered something the Doctor once told her, that every face of a Time Lord came from someone else. Maybe a long time ago, the Doctor met another Billy McFarlane, and that's why he had regenerated into his lookalike.

"Do you want to go back to my place?" Billy blurted out.

"Sure." said Rose.

On the taxi ride there, Rose and Billy were kissing in the back seat when Rose suddenly stopped.

"No, not now. Why now?" Rose panicked to herself.

"Why did you stop?" asked Billy.

"Just... saving it 'til we get there." said Rose.

The truth was that three dinners later, Rose finally needed to poo again. It felt different this time too, like her body was actively eager to release the poo inside her and she only had to let it.

Rose considered if she could hold it until after her encounter. "Nope." she concluded.

"I can change myself at Billy's. I'll just say I need to change myself first."

This thought relaxed Rose. She let go and messed her nappy. She was sure Billy couldn't hear what she was doing because the driver had the radio on and music playing.

"I can't wait to get out of here and use a toilet again." thought Rose.

In Billy's bedroom, Rose and Billy were kissing again. She tore off his shirt and was amazed by how muscular he was, yet not in the veiny way she actually found repulsive. She didn't comment on his physique due to not knowing if it would be a compliment or an insult. Living in a different universe had taught her that the hard way.

Rose put her hand on his chest. She could feel his heart beating. She put her hand on the other side. Only one heart.

Billy took off his trousers. His nappy was plain white with nothing on it except the indicator, which was two thirds full. The sight of a fully grown man wearing a nappy was so absurd it made Rose smile, but he didn't seem to notice.

Rose took off her purple top and laid down on her back. Billy kissed her neck, tits and tummy, then unbuttoned, unzipped and pulled her jeans off.

"FOOTYGIRLZ? You like football?"

"Not really. It's my friend's nappy."

"Fits you very well."

Billy started ripping the tape off her nappy slowly and seductively. It was at that moment Rose realized she had forgotten to change herself.

"Wait! Stop!" cried Rose.

Billy stopped instantly. "What's wrong?" he said.

"I did a poo." admitted Rose, her face burning red.

"That's okay." said Billy. He finished ripping off the tape, carefully slid Rose's messy nappy from under her, rolled it up, disposed of it, got some wipes, cleaned her up the correct way and disposed of the wipes. Then he kissed her pussy instead of putting a new nappy on her.

"Ready now?" asked Billy.

Rose had never felt so humiliated, but she was still incredibly turned on. "Yeah." she said.

Billy ripped his own nappy off and put a condom on. His dick was big, about six to seven inches long. He fucked Rose and for the first time in her life, she experienced multiple orgasms.

After having sex, Billy put a plain white nappy on Rose and taped her up, then he disposed of his used condom, cleaned his dick with a wipe and put his own nappy back on. They cuddled until they both fell asleep.

Chapter Text

The morning after the night before, orange autumn sunlight was shining in and Rose was awoken by a whooshing sound. "Not again." she thought, ashamed. Then she realized with relief that it wasn't coming from her. It was coming from Billy, who was sound asleep. She carefully lifted the cover off him. She could actually see his wetness indicator filling up while hearing him wet his nappy. He kept weeing loudly for what seemed like a long time. Then he stopped just as the indicator filled up. Still asleep. She put the cover back on him.

"Should I wake him and tell him he needs a change?" thought Rose. "No, he looks so adorable sleeping."

Billy woke up anyway. "Good morning. Time for breakfast!" he said once his eyes opened. He jumped out of bed and headed for the door.

"It's a beautiful d-"

Billy stopped and stood still. He made some very Doctorish sounding grunts and the back of his nappy got bigger and bigger. Rose didn't know where to look, but she couldn't bring herself to look away.

"-ay! Care to join me?"

"Actually, I think I'll stay in bed for a while."

"No problem. Have a nice lie in." said Billy as he went downstairs.

Rose began to question why she didn't need a wee like she always does when she wakes up. She lifted the cover off herself and looked down at her nappy.

The wetness indicator was a third full.

Oh.

Oh.

Rose shrugged. She was getting out of here soon. No more nappies. "What time am I going home?" she thought. "Three days and eighteen hours, that's what Pete said. That's four days minus six hours. I got here Tuesday a bit after half past four, so that's Wednesday Thursday Friday... Saturday at half past ten in the morning. That's today."

Rose looked over at the clock on the bedside table. It said "09:45".

"Only forty-five minutes left! Billy might see me disappear in front of him. I didn't even get to say goodbye to myself."

Rose reached towards her chest, where her travel disc should be, but felt nothing. "Where is it?" she worried. She looked around the room. Then she remembered and her blood ran cold.

It was in a drawer at Other Rose's.

If Rose didn't get to it in time, it would return without her. That would mean living in Nappy World forever. She would never use a toilet again. More importantly, she would never find the Doctor, the real Doctor, and every universe would end.

Rose bolted out of bed and got dressed in a flash. She ran down the stairs and past Billy, who was already wearing a fresh nappy and eating a bowl of porridge.

"Can't stay."

Rose burst out of the front door, stopped and looked around. No idea which way she came. She needed a taxi. Pulled out her mobile phone. She needed a number for the taxi.

Rose came rushing back inside. "Give me the number for a taxi." she demanded of Billy.

"09315 444444" responded Billy.

Rose pushed the buttons.

"Hello, Pull Up Taxis." said a male voice on the phone.

"I need a taxi, now." said Rose.

"Where will that be from?"

Rose stared at Billy.

"10 Oaktree Drive, 5AB 5DL" he said.

"10 Oaktree Drive, 5AB 5DL!" repeated Rose.

"And where are you going?"

Rose fumbled in her pockets for the napkin, found out she hadn't got it. She tried to remember the address.

"Flat 34... the Sydney Estate... 8PP 3PU!"

"Okay, that should be with you in about half an hour."

"Half an hour? I need it now!"

"We're experiencing unusually high demand at the moment."

Rose ended the call and put her hand to her head, groaning.

"You seem very agitated."

"I just remembered I need to be somewhere urgently, that's all."

"Where?"

"The hole between two universes is about to close. To keep it open you would need exotic matter, and not even Torchwood has exotic matter."

"I didn't understand any of that."

"It means I'll never see you again."

"I understood that well enough." said Billy. "I'm used to it, being a bit of a beefier bloke. Women think they can take advantage of my low self esteem, but they don't want a relationship with me."

Rose had heard that before. Turns out this universe was similar in some ways to the one she now called home.

"It's not like that at all." she said.

"I bet you were sent to distract the bull so some other girls can chat up my skinny attractive mates."

"I like your muscles!" pointed out Rose. "They're sexy."

"Oh, you have a fetish. I'm used to that as well."

Rose gave up on the conversation and paced about until the taxi arrived. The stress of waiting for the taxi caused her to constantly release small amounts of wee in her nappy.

Rose's mobile phone buzzed. A text message notified her the taxi had arrived. She saw the time was "10:11", waved bye to Billy and dashed off.

"You know, I don't have a problem with most of the immigrants that come over here." began the taxi driver in the middle of the journey, unprompted.

Rose prepared herself to agree with whatever was about to be said.

After a long pause, the taxi driver continued. "But I've heard that in parts of India they don't have nappies. They just poo on the street. They're having to teach em how to use nappies. We've got immigrants coming here from India. Now I don't know about you, but I don't want immigrants who don't even know how to use a nappy. They'll poo on our streets."

"Exactly." said Rose. She remembered that the man driving the taxi last night was Indian, but she didn't mention it.

The taxi stopped outside the block of flats Other Rose lived in.

"It's being a bit slow, calculating your fare. Give it a minute, it's old like me."

Rose looked at the screen in the front of the taxi, seeing the time "10:28". Keenly aware that the fate of every living thing was at stake, she unzipped her jacket pocket and threw the entire stack of £20s at the driver.

"Keep the change! It's a tip!" said Rose, getting out without stopping to look at the driver to see her reaction.

"Rose! Rose!" a female voice shouted as the taxi drove away.

Rose turned around. A butch looking Black girl about her age wearing a wooly hat and dark baggy clothes was sprinting towards her.

"Sorry, but who are you?"

"Oh so you're acting like you don't even know me now. I see how it is, Rose."

There was something so oddly familiar about the way she spoke.

"Oh my god." said Rose, not quite believing it. "You're Vicky... Vicky Smith."

"Course I am, that's me. Knew you wouldn't just forget me like that."

"I don't have time for this right now." said Rose, running into the building.

"Someone didn't come home last night." said Other Rose, who had answered the door in just her bra and nappy. Behind her, in the living room, the bubbly Bunny was sitting on the couch, also in her bra and nappy.

"I went back to this bloke's house." said Rose.

"Nice, well done. We both got lucky." said Other Rose. "Course, it's a lot easier when you're lesbo."

"Right, yeah." said Rose. "No time to chat." she said as she pushed past Other Rose.

Rose ran into her bedroom, frantically pulled open the drawer. She tossed the pants onto the floor and there it was, her travel disc. She put it on, tucked it under her clothes. She stood there for a moment as if expecting something to happen, then looked at the clock. "10:30". It was 16:39 when she arrived, so there were still nine minutes left.

Rose walked back into the living room where Other Rose and Bunny were both standing up now.

Bunny Yang wasn't exactly slim and/or petite like most Asian girls. She was as tall as an Oriental Amazon and as curvaceous as a dumpling, yet she showed no signs of cellulite or other imperfections. One of her arms had a tattoo of a symbol that looked like two crescent moons next to each other with the pointy bits facing both ways, with "WARNING: swings both ways" under it. Her other arm had a tattoo that said "100% CHINESE PORK" in stencil font. The nappy she wore was unlike any other Rose had seen. As well as being massive due to her size, it was dark blue, not white, and covered with little white cartoon rabbits. Her extra-long wetness indicator was about three fifths full.

"Seeing two of you is giving me ideas." remarked Bunny in a voice so American it made Rose's ears burn.

"Well, keep them to yourself." said Rose. She turned to Other Rose.

"Listen, I'm about to leave, in a matter of minutes. Hope they don't use litter trays in the next one. I just want to say, it was nice meeting you, me. I reckon we should all love ourselves more." said Rose, and she gave Other Rose a kiss on the cheek.

"Hey, how come I don't get any of that?" remarked Bunny, and that was when it finally clicked for Rose. Other Rose stood on her toes and gave Bunny a kiss on the cheek.

"I love those diapers you wear. The ones with the little soccer balls on them. They are so cute." said Bunny.

"I love those nappies you wear, the ones with the little... we both call them rabbits, don't we."

Bunny grinned. "Oh, you mean the ones I pee and poop in?"

"No, I mean the ones you wee and poo in."

"Bloody 'ell, I'm weeing and pooing in my nappy." said Bunny in a mock English accent.

"They're bunnies because your name's Bunny. I just got that." said Other Rose. "If I was as fat as you my ego would be out of control too. I could get ones with roses on them."

"Awww, but you'd still be 5'4"." said Bunny, patting Other Rose's head.

"Shut up! I'm 5'5"." said Other Rose.

Rose's mobile phone rang.

"Change of plan. You're not going home." said the older male voice.

Rose's face fell. "What?"

"We're sending you back to that Donna Noble dimension in approximately seven minutes. We think it's special. Not like the others."

"Straight there?"

"Yep."

"Not home and then there?"

"Nope. Straight there. Listen up, this is important. You need to tell her to stay away from London during Christmas. We believe London will be destroyed on Christmas Day. She's got a raffle ticket. The first prize is a luxury hotel weekend break. We've already sent someone to rig the raffle for her. Tell Donna to use that raffle ticket. It could save her life. Have you got all that?"

"Yeah, yeah."

"Oh, and prepare yourself for some jet lag. They're 12 hours out of phase so it's currently night there."

"What was that about?" asked Bunny after the call ended. "Is your sister James Bond or something? How can the same cell divide into such a loser and such a cool person?"

"I think you said something just there." said Other Rose dreamily, who was entranced by Bunny's giant tits.

"I need to get down to ground level." said Rose.

Rose headed off, but stopped at the full length mirror next to the front door. "You can't tell I'm wearing a nappy." she thought as she patted her legs and looked at herself from different angles. She made sure to push down any white ruffles that might possibly poke above the waistline of her black jean trousers. "Donna won't know."

Waiting on the street outside the block of flats, Rose started wishing she had kept the pants instead of tossing them onto the floor. Then she could quickly change into them and wouldn't have to meet Donna Noble while wearing a nappy half-full of her own piss.

Other Rose came out of the block of flats, fully dressed. "I came to see you off!" she shouted from afar.

"Goodbye!" shouted Rose, smiling.

"I have a question! What is this?" asked Other Rose, and she held up the pair of pants. Rose stared and faded away.

A second later, Rose reappeared in a burst of light, hand on her travel disc.

"Give me those!!" shouted Rose as she ran towards Other Rose, but she faded away again before reaching her.
