Sweetie Belle's diaper usage

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.
