Behind Barn Doors

As Canterlot bustled with the sound of high society and commerce, Luna looked down from her tower at her people. After years of tense relations between the princess and the people had finally calmed down, Luna realized that the people still viewed her as less than Celestia. Everything was constantly being judged, from her political abilities to her magic, to even baser matters such as her figure and rumors of how well they are in bed.

Of course, this irked Luna. How could she compare herself to her sister, who has had a thousand years to strengthen relations between herself and her people, not to mention keep up to date on speech patterns and technological advancements within their country? The contest was not fair according to her, and she needed to catch up to the standing of Celestia if she would ever be able to win the hearts of her citizens.

As Luna gazed down at the city, Celestia, who happened to be walking by Luna's room, peeked her head inside. She frowned at seeing her sister sequestered away from the city, knowing full well that Luna wanted to be seen as equal to her. She had begun tutoring Luna on what she had missed during her banishment, but was ultimately drawn away due to the needs of her country. She had tried to make time for Luna whenever she could, but those times were few and far between. As Luna shifted her stance on the railing, Celestia began to have a different thought process at the sight before her.

Her little sister, whom no one could argue was unattractive, was bent over the railing, her rear end sticking outward. Being later in the day, Luna had switched from her regal outfit to something more comfortable, which consisted of gray sweatpants and a dark t-shirt. Standing at six foot three, with slightly pale skin, Luna had kept a well maintained figure throughout her absence, but had grown a little pudgy around the sides, as well as matured as a woman. Her rear had grown from a petite little bubble to a rounder handful, a rear that jiggled quite a lot when Luna jogged. Her hips had expanded as well, giving her a slightly more hourglass figure then before, but wold still classify as 'slim'. Breasts, which were once 34C, had grown to a more than acceptable 36 double D. Needless to say, her new figure had most males hiding their tents of shame, and some females hiding their jealousy.

Without making a sound, Celestia managed to slip inside her sisters' room, gaining her the element of surprise. As she made her way across the room, she picked up a large book from Luna's desk, tightly holding it in her grasp. Celestia stood behind Luna, readying her arms for the impending blow.

Luna only heard the rush of wind before a large smack was delivered to her rear, the loud smack being heard from down on the streets below. The smack startled Luna, jumping up with a loud yelp escaping her lips. Her hands shot to her bottom, attempting to sooth the pain with gentle rubbing. Luna had her eyes shut from the pain, but opened them when she heard the mischievous giggling of her older sister behind her. Luna turned to face Celestia, a frown plastered on her face. At that moment, Luna took a moment to quickly analyze her sister.

Men had been enamored and women have been jealous with Celestia for centuries. Towering above most people at six foot nine, with beautifully tanned skin, many classified Celestia as 'Amazonian'. Her perfect hourglass figure, though slightly more bottom-heavy, had been the envy of many people throughout the years. Her chest, an impressive 38 triple D, sent men and women alike into fits. The crown jewel, though, would be her rear end. What could only be described as 'way more than necessary cushion for the pushin', her rear would be the center of attention whenever she walked away, or knocked something over when turning.

One could easily lose their hand, or head, within the giant cheeks. A slap to them would be the equivalent of startling a gentle pool of water, for once Celestia put motion to her back, there would be no stopping it.

Needless to say, Celestia's ass was legendary.

Luna also noted that Celestia had changed from her regal gown to something more befitting of a princess at rest. Black yoga pants that did nothing to compress her sister's gigantic ass, as well as a stylish red track top, the front open to reveal a plain white tank top. Luna could see that her sister was spilling out of the tank top, but kept that part to herself. After Celestia's giggling ceased, Luna leaned back over the railing, with Celestia joining her.

"We always used to pull stuff like that," Celestia said, remembering times past. Times when the two sisters would run around the palace stark naked in an effort to make the guards faint. Times when Luna would pull the back of Celestia's dress up during an important assembly, or Celestia would pull Luna's pants downward. Simpler times.

"Twas fun. I miss those times," Luna said, sadness dripping in her voice. Celestia looked to her sister, the same mischievous grin still present. "Well, sugar tits, who said they have to be over? We're royalty, but that doesn't mean we can't screw around when nobody's looking," Celestia said, earning a blush from Luna at the name. "So... What? We just start greeting each other with spankings and pantsings?" Luna asked, not realizing that Celestia had moved behind her sister.

"We could, only if you wanted to, little sister," Celestia said, the soothing tone of her voice setting Luna at ease. "I... think I would like that." Luna said, bending over and exposing the thin line of underwear from her sweatpants, giving her sister the perfect opportunity to strike. "I'm glad to hear that, Luna. Say... Do you remember that other prank we used to greet each other with?" The smirk prevalent in her voice. Luna, ever the innocent, was unprepared for what was to come. "No, what?"

Famous last words. Celestia's hands shot forth, gripping the thin line of fabric. Luna realized what was happening, but was powerless to stop it. The burning sensation of fabric grinding in her rear made her wince, while Celestia only felt a savage pleasure from tugging on her sister's underwear.

Celestia was surprised at Luna's choice in undergarments as well. Sky blue boy shorts, ripe for the pulling. Celestia felt the manic smile on her face only grow wider, as Luna began thrashing wildly in an attempt to escape. Celestia, not wanting her sister to evade this prank so easily, used her hidden strength to lift her sister up, her feet now hanging a clear foot away from the floor. Luna could only thrash in agony at the feeling of dangling by her undergarments, also feeling her face heat up in embarrassment at the torture.

"Wedgie!" Shouted Celestia, enjoying the feeling of hoisting her sister up by her panties. She bounced Luna by her underwear, each time earning a grunt of pain from her younger sister. Finally, after a few minutes of tugging and pulling, Celestia dropped Luna back to the ground. Luna, now back on solid ground, began readjusting her underwear which was so rudely hoisted up. She felt Celestia smack her rear again, more gently than last time. "Like old times, sister. We can stop this at anytime if you are ever uncomfortable, Luna," Celestia said, turning to head back into the room.

Luna whirled around, the palm of her hand aimed straight at Celestia's rear. As it connected, the sheer force sent Celestia a few steps forward, a gasp escaping her. The sound of the smack rang in both princesses' ears, one which Luna savored. As Celestia rubbed her bottom, Luna rushed toward her, hand at the ready. Before Celestia could react, Luna grabbed the waistband of her sister's yoga pants, giving them a sharp yank downward.

Celestia, realizing that her pants were now around her ankles, blushed deeply knowing that her younger sister saw her in only her underwear. Luna was surprised to see a bright red thong, with a single heart shaped design on the crotch of the lingerie. Celestia felt the cool air on her rear end, which the very sight of almost made Luna faint. What Luna was not expecting when pantsing her sister, however, was the lipstick-kiss tattoo so prominently displayed on Celestia's right cheek.

Luna giggled at the hilarious tattoo, though Celestia only wanted her pants in their proper place. As Celestia bent over to retrieve her pants, Luna stuck her foot out to stop her sister. Celestia, pull as she might, was unable to remove the foot of her sister from her pants. Celestia stood, and addressed her sister. "Alright, Lulu, you got me. Can I have my pants back now?" She asked, a slight smile coming to her face. Luna, who had been enjoying the sight before her, was in no position for this to end. "Depends. What are you willing to do for them?" Luna asked, a smirk on her face as she did so.

Celestia shrugged, unsure of what she could possibly offer her sister. "I guess... Whatever you want?" She asked with hope in her voice. Luna, who decided to take pity on her sister, removed her foot from Celestia's pants. "I will spare you, Celestia... This time." As Celestia bent over to pull up her pants, Luna delivered one final smack to her sister's rear, this time making Celestia wince. Luna began walking out of her room as Celestia secured her pants. Celestia followed after her, the two now walking down a hallway.

As they did, Celestia reached down to grab Luna's rear end, the soft flesh giving in her hand, making Luna jump slightly. Looking to Celestia, Luna returned the gesture, her hand quickly being enveloped in the mass of flesh. "Just like old times, sister. Just like old times." Luna said, giving a squeeze to Celestia's rear, earning a squeal from her older sister.

With that, the two walked deeper into the palace, sisterly bond strengthened.
