Rarity was in her kitchen chopping up vegetables for dinner Sweetie belle was coming home from school soon. Rarity herself had herself graduated a few years ago but sweetie belle was still in school for another year.
Rarity was humming a tune from sapphire shores newest song. Usually she didn't really like sapphire shores music and only admired her taste in clothes but as her new fashion designer she felt that she needed to understand what her music was about and she had to admit it was quite catchy as she found herself tapping her feet to the tune.
Suddenly she heard the door open she knew it was sweetie belle so she turned around to greet her.
“Welcome home Sweetie be-” She cut herself off when she turned around fully Sweetie Belle was standing there she had grown quite a lot. The eighteen year old had become much taller almost as tall as Rarity. She had started to develop breasts and her hips became more lady like fitting her new figure. She was becoming a young woman but the thing Rarity noticed right now were the tears running down her face. She held her magenta book bag in one hand by one of the straps. She looked so sad which broke Rarity's heart.
“Sweetie Belle whats wrong?” Rarity asked her sister as Sweetie Belle sat down at the kitchen table looking glum as ever.
“Nothings wrong” She answered. Her voice had become slightly deeper but still had that squeaky sound even more so now that she was crying.
Rarity sat down next to her. She knew that wasn't true and she found it weird that she lied to her usually Sweetie Belle was so open about not only her problems but everything this seemed so unlike her to hide something from her. “Sweetie Belle your crying somethings wrong” Rarity said
“I'm fine” Sweetie Belle said as she wiped away her tears she wanted to talk to her big sister about this she really did but she felt so awkward about it and didn't know how to talk to her about this.
“Sweetie Belle talk to me please” Rarity pleaded she couldn't stand to see her sister so sad.
Sweetie Belle looked into the pleading eyes of her sister and knew she could talk to her. “Today in the locker room” She began “I was in my underwear getting changed when Diamond Tiara and Silver Spoon came up to me and started calling my breasts tiny and they kept making fun of me saying that I will never get a boyfriend and no one will ever love me” Sweetie Belle started crying again. Rarity listened with her mouth slightly open.
“Come here” Rarity gently said as she hugged her. “Don't worry Sweetie Belle after dinner I will call the school and have them sort this out” Rarity could no believe that those two bullies said those things to Sweetie Belle.
“Rarity is that true are my breasts tiny?” she asked
“Sweetie Belle you're at the edge of puberty and trust me when I say that it is not easy I had a hard time going through puberty too and when I was your age my breasts were small too,but they will grow and even if they don't you don't need giant breasts to get a boyfriend so don't even worry about it”. Sweetie Belle smiled at Rarity this answer seemed good to her but her smile quickly disappeared
“There something else”.
“What is it Sweetie?” Rarity asked.
“Today when I went to the bathroom I noticed I was bleeding”.
Rarity gasped “WHERE WERE YOU BLEEDING? DO YOU HAVE TO GO TO THE HOSPITAL ARE YOU DYING!!!!!???” Rarity said in her over dramatic way.
“No I didn't bleed a lot just a little bit” Sweetie Belle answered unfazed by her sisters shouting.
Rarity calmed down but was still concerned “Where were you bleeding at?”
Sweetie Belle blushed how was she supposed to say this “Down there” Sweetie Belle answered pointing between her legs.
Now it was Rarity's turn to blush “Oh” Was all Rarity was able to say.
“That never happened before did I cut myself down there or something?”
Rarity sighed. Her little sister knew so little the world and even her own body “Come with me” Rarity said as she got up so Sweetie Belle followed her into the bathroom. Rarity opened the cabinet and started looking through it.
Sweetie Belle wondered what she was looking for but didn't ask.
Rarity finally found what she was looking for her pack of tampons she took one out ripped it out of its packaging.
Sweetie Belle looked at the thing she had never seen before “What that?”
Rarity prepared herself she was about to describe what a tampon is to her little sister “This is a tampon” she said. “Its what women use when they are on there period “.
“Period?” “You mean like at the end of a sentence?”.
Rarity smiled at the naivety of her sister “No a period or PMS is what happened to you today its when women bleed from their ...vagina” Rarity and Sweetie Belle both blushed as Rarity said the last word.
“But how does that help what do you do with it?” Sweetie Belle asked.
Rarity cursed her mother for not telling Sweetie Belle about this sooner “You ...uh stick it ….in...your private part” Rarity wondered why she was not able to say the word Vagina to Sweetie Belle a second time.
Sweetie Belle blushed a new shade of red “Have you ever done that?” She asked.
“Yes I have many times as you will from now on” Rarity was dreading the next thing she was about to say “Sweetie Belle you need to pull down your pants” Rarity blushed.
Sweetie Belle's eves widened “Um ok” She said as she pulled down her pants reveling her pink panties her sister had seen her in her underwear many times but never full on naked. Sweetie Belle nervously put her hands in her panties and pulled down revealing her vagina to her sister. She felt the cold air on her butt and her vagina she had stands of pubic hair there. She then covered her vagina humiliated by this whole situation.
“Ok so take this” Rarity said handing her the tampon trying her best not to stare “And just you know”
Rarity said turning around to respect Sweetie Belles privacy.
“Sweetie Belle took her hand off of her vagina and was about to do it when she realized she didn't know how.
“Um Rarity”.
“Yes Sweetie Belle” Rarity asked still turned around
Sweetie Belle sighed “I don't know how to do this”
Rarity was afraid that she would say that so she turned back around “Okay I'll do it for you” She said as she took the tampon and got down on one knee.
Rarity was beyond nervous for this she had done for herself countless times but never for another person especially not her sister. She stuck it in as Sweetie Belle shivered it took only a second but it seemed to take forever.
“Ok we're done” Rarity said relived. As soon as she said that Sweetie Belle pulled her panties and pants back up.
“Wow there are so many thing about being a women that I never knew” Sweetie Belle marveled.
As they both walked out of the bathroom Rarity had an idea there was so much that Sweetie Belle didn't know about her own body at such an age where she could consent to sex,so instead of learning over time and being confused about certain things why not teach her about it now.
“Sweetie Belle how would you like to learn about the female body and understand everything about your body” Rarity asked her sister.
Sweetie Belle looked up at her big sister thinking about it “Well I mean it could be helpful so something like today doesn't happen again”.
“Ok then follow me” Rarity said so Sweetie Belle followed her into Rarity's bedroom.
Well might as well get started “Sweetie Belle do you remember when we got you your training bra”.
“Yes” She answered how could she forget it was the second most humiliating day of her life. Second only to today where Diamond Tiara and Silver Spoon had called her breasts small and Rarity had seem and stick something into her vagina. In fact she could still feel it in her vagina
“Yes well I never did tell you difference between a training bra and a regular bra and today I am going to do that” She said as she took off her shirt revealing her purple bra.
Sweetie Belles eyes looked at Rarity's breasts. Rarity had seen Sweetie Belle in her underwear many time but never vise versa. Sweetie Belle stared for a while until she realized that she was being rude and looked away.
“No it's ok Sweetie Belle you can look this is supposed to be a learning experience for you” Rarity said when she saw Sweetie Belle look away.
Sweetie Belle started looking again until Rarity said something that caught her off guard.
“Ok so if you will take of your shirt now”.
“What?” Sweetie Belle asked shocked.
“No it's ok you don't have to take off your bra I just want to show you the difference between a regular bra and a training bra”
“Oh ok” Sweetie said relived. She then took off her shirt showing her pink training bra.
“Ok so the difference between a regular bra and a training bra is that a training bra is more lightweight and is for girls who have not yet grown into a regular one”
“Ok” Sweetie Belle nodded
“Alright then “ Rarity said “Now you will learn about breasts” Rarity then strapped her bra off making Sweetie Belles eyes widen. Rarity's breasts were much bigger hers she felt somewhat envious.
Rarity was somewhat humiliated no one had seen her full developed breasts except herself until today but she had to teach Sweetie Belle about this.
“Okay now will you take off your bra” Rarity asked nervously
“Ok” Sweetie belle She had already seen her vagina how are breasts any worse she thought as she took off her bra.
“Now as you can see my breasts are larger then yours but know that yours will grow” Rarity said
Sweetie Belle nodded again
“Now then I will tell you more about the other female private part” She said as she took of her skirt reveling her purple panties.
“Sweetie Belle knew where this was going so she began to strip her bottom half as well.
They both took off there panties at the same time Rarity's had more pubic hair covering it. Rarity looked up and was surprised to see that Sweetie Belle had already taken off her panties. They were both now completely naked. Rarity could see the tampon that she had put in for her earlier
“As you may have noticed” Rarity began “You have begun to grow hair in your vagina and you will grow more there and have what some people call a bush” Rarity explained. “Do you understand” Rarity asked Sweetie Belle.
“Yes” Sweetie Belle answered simply.
“Okay good” Rarity was glad that Sweetie Belle understood but now she was going to teach her something that she was beyond nervous about. How to masturbate.
Rarity took a deep breath and started explaining “Have you ever felt attraction towards a boy?” Rarity asked her sister.
Sweetie Belle blushed “Well there is this boy at my school his name is Button Mash and he's kinda cute”
“Well I am going to show you how to deal with attraction masturbation.”
“What?” Sweetie Belle asked confused.
“Here I will show you” Rarity said as she walked to her bed. As she walked Sweetie Belle could see her Ass as it bounced as she walked.
Rarity masturbated more times then she would like to admit she was taught that it was unladylike but she enjoyed the feeling of an orgasm too much to not do it. She layed down on her bed made sure Sweetie Belle was watching and then she stuck her fingers in her vagina and began to masturbate.
She thought of Fancy Pants a boy she knew from school and would see every so often she wish that they could be together but alas he already had a girlfriend. Rarity moaned as her fingers got deeper forgetting that Sweetie Belle was there she began to move her fingers faster slightly moaning as she got closer to orgasm until she felt the amazing feeling of an orgasm coarse through her body and moaned loudly. She was left gaping for air afterwards.
“So is that masturbation?” Sweetie Belle asked awkwardly.
Rarity almost fell off her bed when she heard Sweetie Belle's voice and blushed the deepest shade of red all day she was mortified she just masturbated in front of her sister of course she meant too but not with all the moaning and gasping.
“Um yes you don't have to try it if you don' want to I was simply showing you how..”
“I want to try it” Sweetie Belle cut her off “But can you watch me and make sure I am doing it right” Sweetie Belle asked embarrassed.
“Um.....yea.....sure” Rarity answered shaken up by this whole situation. She had some trouble getting up after that orgasm but was able too.
Sweetie Belle layed down on the bed and stuck her fingers in her vagina like Rarity and began moving her fingers around but nothing was happening “I don't feel anything” she said.
“Try thinking about that boy you like” Rarity answered.
Sweetie Belle began to think about Button Mash she was starting to have this amazing feeling between her legs and started to move her fingers faster a soft moan escaped from her lips. The feeling became more intense and she was moaning more.
“RAriTy!” The letters came out at different volumes “WhAT Do III dO NOW!!!
“This is called an orgasm honey just keep going” Rarity explained.
She kept going and was constantly moaning this was like nothing she ever felt. Then she reached orgasm and let out one final moan. Sweetie Belle was shaking on the bed from it.
“So how was it?” Rarity asked.
“Amazing” Sweetie Belle answered simply “Thanks Rarity”.
“For showing you the best feeling in the world?” Rarity asked with a smile on her face.
“For teaching me everything about my body and helping me”.
“Thank you and if you ever have any questions any at all come talk to me about it okay”.
“Okay” She said as the two naked sisters hugged.
“Now let's get dressed and go have dinner” Rarity said.
“Yes oh man I am so hungry” Sweetie Belle said as she got up.
“Yup an orgasm will do that” Rarity smiled.
Sweetie Belle blushed and then smiled at her as they got dressed.
