Filling Out the Throne


                                            1.
                                            
                                                It was a peaceful night in Equestria. No manner of creature was stirring in their bed as a certain princess of the night swam through the realm of dreams. “Perfect. Not a single nightmare, bad dream or even restless night. I think I deserve a small break.” Princess Luna smiled as her magical projection faded from the Dream and returned to her body. The dark blue alicorn opened her eyes and stretched her legs before hopping to her hooves.

                                            2.

                                            3.
                                            
                                                “Another night almost gone. I should take a stroll and enjoy what's left of the starry sky.” Princess Luna spread her wings and soared to the gardens. Her hooves crunched the grass as she trotted through the lush maze of plants and flowers. Luna slowed down and looked up at the sky, smiling as the twinkle of the stars lit her way through the dark.

                                            4.

                                            5.
                                            
                                                The guards nodded as she walked through the halls. An army of silent protectors watched as their princess aimlessly drifted around the castle. “Nopony left restless in the castle. Perfect.” Princess Luna smiled as she let herself into the throne room.

                                            6.

                                            7.
                                            
                                                She looked upon the impressive thrones sitting atop the stairs and smiled. “I see Celestia has finally added a proper throne for me to have in case I'm needed during the day.” Princess Luna walked up to her throne and sat down, cooing in delight as she relaxed in the giant seat.

                                            8.

                                            9.
                                            
                                                Princess Luna giggled as she let herself go slack in her chair. “Ahh, the real perks of royalty. A comfy place for your butt no matter what you're doing.” She turned her head a little, squinting at the throne next to hers. “Is...is mine smaller?”

                                            10.

                                            11.
                                            
                                                Soft flapping filled the room as Princess Luna pulled herself into the air. She extended her hoof out to the top of her throne and compared it to the height of her sister's chair. “She DID make it smaller!” Luna puffed out her cheeks in annoyance. “Celestia ALWAYS makes my things smaller! I'm not JUST her little sister.”

                                            12.

                                            13.
                                            
                                                Luna looked around the throne room for a moment. No guards bothered to stay stationed in the throne room during the night. A perfect opportunity for mischief. As quick as Rainbow Dash, Princess Luna dove into her sister's throne and smirked. “Ha! Now I'M the one in charge! Servant, do these taxes and accounts. You there, fetch the next peasant that needs an audience. Guards, fetch me my cakes!”

                                            14.

                                            15.
                                            
                                                The silly princess burst out laughing, flailing her legs about as if she was made of rubber. “How  incredibly ridiculous of me. Then again...” Luna reached her forelegs out and scoffed as she realized how tiny she seemed in the throne. “I suppose I wasn't too far off with that cake line. Sister DOES have a fairly large rump.”

                                            16.

                                            17.
                                            
                                                “I suppose she can keep her big throne for her big butt. By no means is Celestia fat, but I could barely recognize her with those wide hips.” Princess Luna sighed as she pulled herself from the chair. “No need to be so venomous. Celestia cares for me and that's all I need.”

                                            18.

                                            19.
                                            
                                                As Luna shifted her weight, her hoof slid down and bumped into a small bulge sticking out in the chair. “Oh my...what is this?” Luna pushed her hoof into the dent and gasped as it clicked into the chair. A sudden grinding filled the air as a nearby wall lifted up to reveal a hidden room. “Oho, what's this? A panic room perhaps?”

                                            20.

                                            21.
                                            
                                                Princess Luna got up from her sister's throne and peeked into the new room. She gasped as she looked inside to find a dragon's hoard of cakes stacked to the ceiling. “Oh my goodness...perhaps that cake comment was spot on.” Princess Luna giggled as she looked at the stash of sweets. Shelves and shelves were lined with cake. Far too many for Luna to count by herself.

                                            22.

                                            23.
                                            
                                                “So my sister has a secret room...for cakes?” Princess Luna burst out laughing, her knees growing weak as tears began to well in her eyes. “Seriously? Of all the things she needs to hide, she hides cakes?”

                                            24.

                                            25.
                                            
                                                “Not like she can hide that fat rear of hers.” Luna continued to tease. She picked herself up from the floor and sighed. A small blush rushed to her cheeks as Luna's tummy grumbled with hunger. “Goodness, the night flies when you're having fun.” Princess Luna looked over the closest cake and licked her lips. “I doubt Celestia will miss just one. There's enough here to feed an army for days...”

                                            26.

                                            27.
                                            
                                                Princess Luna eased herself back into Celestia's throne and smiled. “Now for the real experience of being my sister.” Princess Luna cut a slice of the yellow cake and nibbled it. “Oh...MY. This is delicious!” Princess Luna moaned as she took a proper bite, not caring if a bit of frosting was stuck to her mouth. “What a flavor. The lemon goes great with the sugar and the frosting is light and fluffy.”

                                            28.

                                            29.
                                            
                                                Another swallow triggered another moan to echo through the empty throne room. “Where does she even get incredible sweets? I swear, no cake I've ever tasted even compared to this.” Before Luna knew it, the entire cake was sloshing about in her stomach. The stuffed princess reclined in the throne and belched as loud as she could.

                                            30.

                                            31.
                                            
                                                “Ah...princess life at its finest. No wonder Celestia is so thick.” Princess Luna giggled as she struggled back to her hooves. “How do I close this thing?” Luna grumbled as she walked back to the secret room. Her worries were banished from her mind as another sugary cake filled her vision. “Oh, that one looks quite scrumptious...one more wont hurt, will it?”

                                            32.

                                            33.
                                            
                                                Princess Luna pulled the cake back with her to Celestia's throne and cut it up just as before. The greedy alicorn chomped through it even faster than her first cake, relishing every bite as the sugar swam over her tongue. “Ah...fantastic.” Her magic reached into the room and grabbed a third cake for her to enjoy.

                                            34.

                                            35.
                                            
                                                The slices grew bigger and bigger as Luna demanded more. Frosting was smeared all over her face, her stomach was bulging over her lap and still the princess craved more. She stuffed herself silly as the decadent, rich flavors sent her head spinning. Chocolate, vanilla, hazelnut, frosting, filling and flavor all combined into a gigantic calorie bomb bloating out her stomach.

                                            36.

                                            37.
                                            
                                                BUUUUUURRRRRRRRPPPPPPP

                                            38.

                                            39.
                                            
                                                Princess Luna moaned as she slumped back into the throne. She struggled to breathe as her heavy stomach weighed her down. “Good....goodness....amazing.” Princess Luna looked down at her stomach and blushed as a flabby, wobbling orb bounced with her every breath. “Oops...”

                                            40.

                                            41.
                                            
                                                “I overdid it.” Princess Luna groaned. She reached out with her hooves and rubbed the distended blue orb. A few extra belches escaped her lips as Luna eased the tight pressure in her gut. “Ahhhhh...there we go.” With the pain gone, Princess Luna sat in her sister's throne and relaxed.

                                            42.

                                            43.
                                            
                                                “Celestia is gonna kill me when she finds out how many cakes I stole.” Her stomach sloshed and glorped in agreement as her whole body softened as her late night snack digested in her full belly. “No way I can cover this one up.” Luna blushed, unsure if she meant her gigantic, flabby tummy or the missing cakes. “Well, it's as they say. In for a penny, in for a pound.”

                                            44.

                                            45.
                                            
                                                As if accepting her fate, Princess Luna smiled as she grabbed a few more cakes with her magic. The greedy mare let herself consume as much as she wanted while rubbing her growing gut. She moaned in delight as she swallowed and grew, biting her lip as she felt the once wide armrests grow snug and pinch her ballooning body.

                                            46.

                                            47.
                                            
                                                There was no stopping her. Princess Luna was on a mission to devour as much cake as she could. Not even the setting moon nor the rising sun could distract the hungry mare as she ate and ate. Every little wobble of her stuffed gut sent a tingle through Luna's body as she crammed a set of miniature pastries into her mouth.

                                            48.

                                            49.
                                            
                                                “What....in EQUESTRIA is going on??” A voice boomed into the empty throne room. Princess Luna struggled to look over her swollen, cake engorged gut to spot her sister standing in front of her. Her hair flickered with rage as the peaceful, muted tones of Celestia's mane were replaced with a cackling inferno.

                                            50.

                                            51.
                                            
                                                “Midnight snack?” Princess Luna chucked as she slapped her gut. It wobbled hard, forcing a gigantic belch from the glutton's mouth. Princess Luna's entire body rippled along with it from her chubby face all the way down to her pony sized flanks and overstuffed stomach.

                                            52.

                                            53.
                                            
                                                “Snack? Dear sister, a SNACK is one slice! And what are you doing in MY THRONE? Remove yourself at once!”

                                            54.

                                            55.
                                            
                                                “Fine...spoilsport.” Luna grumbled as she leaned forward. She huffed and puffed but the well fed mare didn't budge. “Aha...seems I've become the bigger sister, now. I'm stuck.” Luna continued to chuckle at herself until the sound of cracking filled the air.

                                            56.

                                            57.
                                            
                                                Before either could react, the heavy marble throne collapsed. Luna's wide flanks and plump hips snapped off the solid stone armrests while her incredible weight forced the backrest to tilt and sway. “WAAAAHHHH!” Luna screamed as the backrest fell to pieces. She slammed onto her back, sending her belly into a wobbling fit as it towered above her.

                                            58.

                                            59.
                                            
                                                “My throne!” Celestia wailed as she walked up the steps and surveyed the damage. She looked over her obese sister as best she could, lifting up patches of blue flab to peek under the greedy mare happily belching and rubbing her own gut.

                                            60.

                                            61.
                                            
                                                “Just admit it. You hate being the little sister.” Luna smirked as she ran her tongue over her lips.

                                            62.

                                            63.
                                            
                                                “...You know what? That's perfectly fine with me.” Celestia smirked as she lit up her horn. “You want to be the BIG sister for a change? You'll get that wish, Luna.” In an instant, over two dozen cakes were swirling in the air above Luna's head.

                                            64.

                                            65.
                                            
                                                Celestia forced Luna's mouth open wide as she crammed the first cake inside. Princess Luna could only squirm and moan as it all slid into her over-packed stomach. The sun princess watched with delight as Luna's belly bloated out another inch as it struggled to digest so much cake so quickly.

                                            66.

                                            67.
                                            
                                                “It must have been hard to resist. Most of those cakes are made by grand masters of their trade. They spend HOURS on just one cake to make it perfect.” Princess Celestia walked around her sister as she forced another cake into Luna's mouth. “A perfect mix of sugar, flavors and frosting as an offering to me that I gladly pay double for since they are beyond divine, and yet here I find you just stuffing your face with it all.”

                                            68.

                                            69.
                                            
                                                Princess Luna let out a sickly moan as Princess Celestia pushed into her sister's gut. “Don't you worry, Luna. You'll have all the cake you could ever want. I keep around a thousand cakes in that room, all perfectly sealed for when I so choose to have a SLICE. You better be ready to keep swallowing for days, dear sister.”

                                            70.

                                            71.
                                            
                                                Regret and pain flooded Princess Luna's stomach. Even with such delicious flavors, she was impossibly full. Each bite made her skin crawl as she was forced bigger and bigger as Celestia watched. “Sho...fuuuullllllll.” Luna whined between bites.

                                            72.

                                            73.
                                            
                                                “Oh, so NOW you only want a slice or two? You could have just asked me for some of my special cakes.” Celestia teased as she rubbed Luna's stomach.

                                            74.

                                            75.
                                            
                                                “Noh....nohhhhhh mooorrrrre.” Luna pleaded as an angry glorp sent her whole body wobbling. Her stomach was as tall as Princess Celestia at full height, towering over all like a massive, flabby blueberry. Her flank was round and flabby as it completely hid the remains of Celestia's throne as her belly sagged and spread over the floor with every forced bite.

                                            76.

                                            77.
                                            
                                                “I would have happily shared it with you! Maybe even offered you a cake or two. Now, it seems like you better be ready to eat ALL of them.” Princess Celestia giggled as another cake disappeared.

                                            78.

                                            79.
                                            
                                                “Sis...shishta....pleeeeaaaaaassssse.” Luna continued to whine through her heavy bites. Her stomach sloshed as she struggled down another bite, forming another flabby roll on her whale sized tummy.

                                            80.

                                            81.
                                            
                                                Princess Celestia smirked as she prodded Luna's tummy. As full as she was, Luna's rolls of blubber were incredibly soft and squishy. The sun princess bit her lip in excitement as she turned around and plopped her rear right onto Luna's stomach. Celestia cooed in delight as she reclined into the mountain of blue lard. “You make quite the seat, dearest blimp of a sister. You know...I might not need to replace my throne after all...”

                                            82.

                                            83.
                                            
                                                “Full....oh gosh.....shtop....fuuullllllll!” Luna whined as she swallowed another cake.

                                            84.

                                            85.
                                            
                                                “I WILL have to restock my cakes, however...” Princess Celestia winked as she took a slice for herself while forcing the rest into Luna's mouth. “About one hundred cakes down, Luna. Another nine hundred to go...”
