The Secrets of the Moon Princess

Luna Goes home to the Canterlot Kingdom quietly so no one notices , She went to her room sneakly , She opens the door and an alicorn stands there with the name 'Princess Celestia'

"where have you been dear sister!?" with an angry facial expresion, Luna replied "I-I was just visiting your s-student t-twilight...." , "uhu...what were you doing there?" , "I-I was just getting rest b-because my wings were tired from flying to ponyville...." she replied , "is that all? i dont really think thats all...." Celestia says with a curious face , Luna shouted "OK! I WAS MATING WITH TWILIGHT AT HER TREE HOUSE!!.....happy now?" Celestia was shocked as she slaps her sister at the cheek "W-Why would you do that!?" Luna replied "b-because i was bored....and i saw twilight reading a certain 'book'...."

Celestia leaves the room and goes to her own room , thinking "has Luna really been having sex with twilight!?! , is she finally getting those hormones that makes her really horny?!?.......like mine?......" Celestia comes back to Luna's room with a seductive face and a bag "W-What's with the f-face and t-the bag big sis??" , "oh nothing~" Celestia replies as she pins Luna to her bed and kisses her "a-ah! no please dont!~" , "oh i know that you like it deep inside of you dear sister~" as she licks Luna's horn all around and begins to suck on its tip , "o-oh~ p-please big sis~ continue!~ .....WHAT AM I SAYING!?! please stop big sister!!"

Celestia was surprised she said those exact words 'please big sis. continue' as she suddenly puts luna's horn into her mouth and begins to give her a BIG hornjob

Luna was already shooting magic out of her horn a little and her body lost controll and suddenly puts her hoof on Celestia's marehood , she rubs her sister's marehood in a fast motion

Celestia was already getting wet because of the fact that she's doing it with her sister , Luna licks her hoof and suddenly released a great moan of pleasure as her horn suddenly starts shooting tons and tons of magic particles in celestia's mouth

Celestia's marehood was dripping juices because of the pleasuring taste of the magic that luna spurted all over her mouth , Celestia goes down to her sister's marehood and licks all the juices up as she sucks on Luna's marehood

Luna was moaning loudly out of the great pleasure her sister is giving to her , She begins to check the bag that her sister brought and she sees 'beads,vibrating dildos and other stuff , She begins to take the beads out and hands it to her her big sister "C-Can you please p-put that i-inside of me?" Celestia nods as she slowly puts it inside Luna's anus

Luna was tearing up a little from the pain but moaning still from the pleasure , her marehood begins to spurt out more juices and Celestia begins to suck on Luna's marehood as she keeps pushing the beads inside of her , Celestia's horn was suddenly glowing and dripping some of her magic particles

Celestia asked Luna if she could rub her hooves on her horn , Luna nodded and did what she was asked , "oh~ dear sister!~ your so so so good at this~" Luna blushed as she licks the tip of her sister's horn

Celestia suddenly puts a dildo on Luna's marehood and turns it on for it to vibrate inside of her , Luna moaned in such pleasure she have never experienced before , She suddenly orgasmed all over it and Celestia takes it outside Luna's marehood and licks it all up , Luna pulled the beads out and puts it into her sister

Celestia moaned loudly as she puts her horn on Luna's mouth and Luna quickly licks it and sucks on it while her hooves were rubbing it , Celestia is so surprised at her sister for doing this , She starts to spurt more of her magic particles in luna's mouth as Luna stores some of it under her tongue

Luna stops and suddenly kisses her sister deeply to release the magic particles under her mouth for both of them to share it , Celestia kisses back and licks some of it up inside her mouth

"I think its time for us to stop and rest big sis...." as she yawns , "dawwwwwww!! hmp...ok maybe it is time..." Celestia replies as she goes outside Luna's room and back to her room "ohh yes...that was...really great" as she falls to her bed and sleeps.
