It was a Friday Night in Ponyville, Sweetie Belle arrived at home after an exhausting afternoon with her crusaders friends. The interminable cutie mark quest was very stressful. She dined daisies sandwiches and apple juice, the favorite dinner of the white unicorn, after the dinner Sweetie Belle went to her room and read some books. Her favorite books were the magic books. Since she started learning magic with Twilight, she had read a lot of books. But the naughtiest thing in that night started after the 10 o’clock when her parents went to bed and it supposed she too. Before all the lights were turned off, Sweetie took a shower. In the dark bedroom with only the moon light, she had lit a lantern and sought a special package between all her pretty dresses and school books, in the deep of her closet she took a diaper pack, in the front had the picture of a young filly using one, and a phrase who says “Filly protection diapers”, she put it on her bed and saw quickly all the messages about her new purchase, these diapers was especially for bed wetter and incontinent fillies, the tag says “medium size, for fillies from 8 to 10 years old”, in the other side was some pictures of the diaper equipment and that had a message too and it says “It supports until 2 urine liters” and "The solution for the wet troubles of your little filly". Sweetie Belles’ heart was beating fast, she was excited, she was going to open her first diaper pack, only for her little fun, but, why a filly who never had bed wetting or incontinence problems bought a diaper package?, Sweetie Belle had an interesting experience some weeks ago:
It was a Sunday morning, the night before Sweetie Belle’s family had a little birthday party for her cousins, the unicorn woke up that morning with an uncomfortable sensation, her bladder was totally full, the previous night she drunk more juice than other days and with all the fun fo the party she simply fell in her bed forgetting use the little fillies room before, in fact, she was lucky hadn’t wet her bed. She had to pee really, really bad, only a few seconds after his hard awakening she stood quickly and put his front legs in her urethra trying keeping the gold liquid inside her body. A few minutes after, she ran quickly to the bedroom’s bathroom but was locked.
“Sorry Sweetie, your uncle is taking a bath, and he have to go to Baltimare quickly” said her mom.
“How long will he take?” asked worried the white filly
“Maybe ten minutes” answered his mom
“Ten minutes? Oh no!” said Sweetie Belle for herself, she thought she only had one or two minutes before be totally soaked by her own yellow liquid, she ran quickly to the hall's bathroom, there was locked too, after, she ran to the garden, despite she disagree about relieve oneself outside. It was an emergency, but her cousin was playing in the garden. She simply couldn’t urinate with other ponies close. Finally, she went inside again and totally desperate began crying before she saw a diaper package in the visitors' bedroom, she thought it a moment and quickly took one of them and put it herself, she was really lucky, the diaper had almost the right size, although her back legs were really tightened. At least one second she started the bladder’s muscle relaxation and all the urine went out of her body, she felt heat while her diaper were totally soaked, the size of the diaper were grew at least the double, and even she couldn’t walk, she were totally paralyzed while she was peeing, she never couldn’t stop her squirt force until she finished, when all the content of her hurting bladder come out she finally left relaxed and a little excited, she fell down in the floor and sat on a soaked diaper, the liquid at the diaper began cool down and Sweetie Belle finally removed her the diaper and she throw it in the rubbish. She had never felt that exciting sensation before, the sensation of pee yourself with all your liquid gold just under you, the sensation of a secure padded garment mild and comfortable, she looked at the room’s mirror one moment, she thought she was really cute at diaper wearing, just like a big adorable baby. Her parents, her cousins and her uncles never knew about her little act, and she never told anything.
That night she want to repeat the previous experience. She bought the diaper pack in a shop close of Ponyville School. With a little magic help, she finally opened the package, inside were ten diapers, she could feel quickly an foal smell, she took up one of the diapers and saw it, the size apparently was right, but she needed to prove them to be sure, she put herself the padded thing in her body, her private parts were totally hidden when she looked herself at the mirror
“I look so adorable” said Sweetie smiling to the mirror.
“All right! Let’s start!” said before take a water bottle and begin drink it. While she was waiting, she took another magic book, “basic usage spells” and read it by one hour. She finally began feel some bladder pains and the real urinate need. She separated her back legs and began the muscle contraction, she did her best but even a little urine drop didn't go out.
“Oh come on!” screamed, she was frustrated, she really had to pee but years of sphincters control made her bladder shy at that moment.
“Maybe I have to lie down” said before fell on her bed like she were going to sleep, she continued feeling all the liquid wanting leave her bladder, but she simply couldn’t do that, she tried think soaked places, the sound of the rivers, the sound of a morning urination and finally a little yellow squirt get out in the diaper, she was happy but there was a lot urine in her bladder yet. She stood up again and applied force in the down zone of her body, slowly, little urine squirts goes out and after few forced minutes, her bladder was finally emptied, and her diaper, well, her diaper had a big yellow spot in front and were totally soaked inside.
“You’re a bad filly Sweetie Belle” said for herself. “I maybe need a diaper change… no, I am so tired” she said before sleep.
The next day Sweetie Belle began to feel a little strange sensation in her private zone. She couldn’t see the wounds before she looked herself at mirror, around her back legs and really close to her marehood were an unusual red color, and an itchy sensation.
“All right! Sweetie stay calm, you only have to… maybe use a skin cream, that’s it” said worried the little filly. Sweetie Belle’s mother call her for breakfast. Sweetie Belle walked trying to hide the wounds, fortunately her parents didn’t see anything while they were eating.
“Well… I’ll go to Rarity’s boutique, bye!” said trying going out quickly.
“Wait Sweetie, Had you forget give me a hug?” asked her mom.
“Sorry mom” said while she hug her mother, the hug excitement makes her become visible her wounds.
“What’s that?!” asked worried her mom pointing the filly’s private parts.
“Oh that, well…. I don’t know” explained Sweetie Belle, her mother even hadn't waited one second and ran outside holding her son. Sweetie was totally scared. Her mother led her to the closest hospital.
“But mom, I’m ok…” said still scared the filly.
“But you don’t look good” explained her mother, after few minutes the two mares walked to the doctor's office, the doctor revised Sweetie Belle’s body looking for issues.
“Sweetie Belle had used diapers recently?” asked the doctor, Sweetie Belle got totally cold, she was going to answer the question when her mother interrupted.
“Of course no! Why do you ask a silliness like that?”
“Well, this kind of irritation appears when a filly or a foal use diapers” explained the doctor
“Just forget it, use this skin cream and the irritation will disappear in few days” explained the doctor who gave to the mother a cream jar, finally the two mares came out of the hospital and Sweetie Belle could go to her sister’s boutique.
Sweetie Belle used the skin cream for few days and the irritation disappeared completely, she understood that she have to use that cream before and after diaper usage or her mom would suspect. At the next Friday she wasn’t totally sure if she could continue with her little diaper game. Her parents traveled to Canterlot and she had to stay with her big sister all the weekend. Before the short ride between her home and Rarity’s house, she put a single diaper in her saddlebag. Her big sister would never know about that, she’s always concentrate in her job even at weekends.
The afternoons at Rarity’s house are usually boring. Sweetie Belle was all the afternoon doing homework, drawing and reading book. In fact she found an interesting spell in one of the books, it was a "hidden objects" spell, that’s right. It is a spell which can hide small objects.
At the night, Sweetie Belle went to bed early, her sister did it too. She was again in a dark bedroom with a diaper which her sister would never find. She makes a simple light's spell and put a little amount of skin irritation cream at her lower body parts, finally she could put herself the diaper, and the water drinking race began.
One complete water liter in her stomach, at that point the urination need was really small, she decided drink one more water liter.
One hour had past and the urination need was in a medium level, she tried go pee in her diaper but she couldn’t. Her bladder shyness grew that night. She lied down at her bed and stayed asleep. She didn’t want sleep with a full and shy bladder but she was really tired that night. However the filly couldn’t sleep so much time, only one hour after, she woke up suddenly, her bladder was asking screaming an urgent emptying. Sweetie stood up and relaxed all her muscles for a really urgent urination. It appears she couldn’t urinate when she was lied down, or maybe her bladder always asked her before an emergency emptying. Just like the last Friday, the yellow liquid began falling down in her diaper. She was needed a hard effort to force all the urine get out, as a filly who never had been incontinent or bed wetter isn’t easy urinate anywhere. Finally after five minutes doing efforts, she felt totally emptied. Her diaper apparently absorbed all the urine, but when she lied down again felt a wet sensation, just like she were swimming in a pool. She ignored it and returned to sleep.
At the morning the sun was shining at the bedroom’s window and Sweetie Belle woke up. She felt again the wet sensation like the last night, she began feel uncomfortable almost swimming in her own pee. She removed her diaper and put it at the floor. Fortunately she hadn't skin eruptions or irritations, but when she puts the used diaper at the floor, she looked how a urine puddle was trying to get out of inside the diaper, in fact some drops fell down and wet a part of the floor, and also, the bed had a little spot. Finally the unicorn noted how little drops fell down from her marehood, actually, all the zone was soaked with a liquid with a strong odor.
“Of all the worst things that could happen, this was THE. WORST. POSSIBLE. THING!” this was the Sweetie Belle’s thought when her big sister appeared in her bedroom, Rarity were paralyzed watching the wet objects and the wet lower body parts of her little sister, Sweetie Belle had a similar sensation but maybe worse because she was the guilty. Sweetie also did the spell which learned the last afternoon and the soaked diaper were hidden from the normal view.
“Did... you wet the bed?” asked Rarity totally surprised.
“Mmmm… yes, sorry big sister” answered worried Sweetie Belle.
“But… but I don’t understand it, I’ve cared you almost nine years and you have never had that problem” said Rarity.
“It was an accident” said Sweetie Belle.
“Maybe, but our parents have to know it. I’m going to tell them tomorrow” said Rarity.
“No! Please, sister, don’t tell my parents about this” asked Sweetie Belle totally desperate.
“Don’t worry little sister! They will help you with your little trouble” said Rarity starting cleaning the bedroom.
“You don’t understand sister… I’m going to tell you what happened” said totally sad Sweetie Belle while was undoing the hidden spell.
“A Diaper? But… Why did you used a diaper? And, why the diaper is totally full?” asked confused the unicorn while she was seeing the strange object.
“I need you promise don’t tell it to anypony” said crying Sweetie Belle.
“I used that diaper on purpose” continued.
“But, why?” asked Rarity.
“I only wanted have fun and be a little naughty pony, Is it bad?” said Sweetie Belle.
“Well, it isn’t, in fact, I had done antics like that in the past” answered her sister.
“Really?” asked surprised Sweetie Belle.
“Yeah, doing antics sometimes isn’t bad, but you have to be careful. Just look at that! You made a disaster here” explained Rarity.
“I can clean all your house if you don’t tell it to anypony” proposed Sweetie Belle.
“Don’t worry little sister, your little secret is safe with me and we can cleaned the boutique together” said Rarity. The two ponies cleaned all the house that morning, Sweetie Belle had to work hard but she was happy, her antics hadn’t done great troubles.
In the afternoon, the sisters went to take a tea cup.
“And… Did you say that you look cute in diapers?” asked Rarity.
“Well… I think so…” answered shy her little sister.
“Can I see that?” asked embarrassed Rarity.
“Are you saying you want I put me a diaper?” asked Sweetie Belle.
“Well... maybe” answered Rarity. Sweetie was totally embarrassed, but she thought that could be her unique chance in her entire life.
“I can do it, but, I need to go home first, and…. maybe…. Can we play a little game tonight?” said Sweetie Belle.
“What kind of game?” asked confused Rarity.
“A little sister diapered game” answer the little unicorn.
“I see… that’s ok little sis, we are going to play, but It will be only tonight” clarified Rarity. The two ponies went to Sweetie Belle’s house and took some equipment for the night. Clean diapers, a cream bottle, and Sweetie Belle’s favorite pajama.
At the night Rarity put away all her job equipment and stayed with her little sister. The night was young and the house was only for the two nearby sisters.
“Can we start?” asked Sweetie Belle.
“Of course!” answered Rarity.
“Well… Do you like put the diaper on me?” asked Sweetie Belle.
“I had never changed a single diaper” explained Rarity.
“You can do it, It’s easy, and besides…. I will be a good girl” said Sweetie Belle.
“Ok, let's do this” said insecure Rarity before start the unknown operation. She take a clean diaper and put her sister over then. She followed the filly’s instruction all the time for avoid mistakes, finally the diaper was almost post. She put the tapes in their place and her first diaper change was complete.
“Good job, big sister, you’re ready to be a mom” said laughing the padded pony. She stood up and looked herself at the bedroom’s mirror.
“What do you think sis?” asked Sweetie Belle.
“You are the cutest sister that I had ever seen” answered Rarity.
“I’m the unique sister that you have” said laughing Sweetie Belle. After that chat, Sweetie Belle put on her pajama. The night was quiet and peaceful, the two sisters had an interesting chat about the school, the job, their friends and other nice topics. “Can you carry me?” asked Sweetie Belle. Her sister accepted and carried her little sister for a while.
“What are you doing Sweetie?”
“I only will say that I didn’t go to the bathroom since the lunch” explained Sweetie Belle starting the muscle relaxation.
“Are you going to pee?” asked worried Rarity.
“I’m going to try it” answered Sweetie Belle.
“Are you crazy? Take off that stupid thing and go to the bathroom now!” said angry Rarity.
“Come on big sister! The last part of our game. Please?!” asked Sweetie Belle.
“Ok, but please, do your dirty act far from here” said Rarity, Sweetie Belle accepted. She knew if she continued asking favors her sister wouldn’t be happy and her secret would be revealed.
“You can do it Sweetie Belle! You are using a diaper, your big sister is behind you, but you can do it” said for herself the padded unicorn. She began the muscle relaxation, but her urine simply couldn’t go out even after five complete minutes.
“Have you finished?” asked her sister who was looking to the opposite direction.
“No, sorry, give me two more minutes” said the worried pony trying to go pee in her diaper, after another five minutes, she finally gave up. Her bladder was too shy at that moment.
“Well… Better we go to sleep, is too late” said Rarity. The two fillies walked across the boutique, Sweetie Belle couldn’t walk properly because she had two troubles. First, the diaper prevented her normal walking, and second, her bladder was asking screaming an empting.
Before they arrived to the bedrooms a whistle began to ring, that’s it, Sweetie Belle was peeing but this time, it was an accident. Sweetie Belle have never had an accident before, even with the most urgent need of pee, the sensation was totally exciting but her big sister was only few meters. Sweetie Belle was totally embarrassed when the yellow liquid left her bladder really fast. With a totally quiet environment Rarity could hear the dirty act of her little sister who had stopped in the middle of the corridor. 30 seconds, one minute and finally after two complete minutes, the padded pony ended. Her diaper were totally wet, but this time there wasn’t leaks. It was by far the naughtiest and shameful Sweetie Belle's act.
“We will never say a word about this” said shocked Rarity.
“You said it” confirmed Sweetie Belle before a new diaper change, the last one at Rarity’s boutique and went to sleep. “You said it” confirmed Sweetie Belle before a new diaper change, the last one at Rarity’s boutique and went to sleep.
