Princess Celestia was in high spirits as she trotted down the main street of Canterlot. “Good afternoon everypony, beautiful day we’re having!” she practically sang as she cantered along. The princess had been making more and more public appearances recently, and it was no secret she was enjoying them hugely. All eyes, especially from stallions, were on her as she made her way down the road towards the castle.
“How much bigger do you think she can get?” came a whisper from one colt to another.
“I don’t know, she’s a princess, thousands of years old. Nopony KNOWS what her body is capable of.” came the reply. The princess picked up on their whispering and smiled to herself. It was true, she had been piling on the pounds recently, looking after a kingdom was highly stressful. She needed some way of blowing off steam. Over the thousands of years she had tried many things, but recently for some reason eating had become a passion of hers.
She had never really thought about it much before, eating to her before was like anything else. Something she did 3 times a day like anypony else to keep herself alive and energised. But it had happened a little while ago during one of the many banquets, for some reason the kitchen staff had run out of their usual endless supply of starters and main courses so via someponys wisdom they had decided to substitute all of it with desserts. She had struggled at first to maintain her usual composure, but as the night went on she had been trying more and more, and by the end of the night she had not only gained quite a few pounds but also developed more a taste for all the delicious desserts she had eaten that evening.
The only thing, and a very small detail really, was that most of it seemed to be going to her ass. She was not fat by any means, but her rump had really piled on the pounds. Whereas before it was slender and small, it was now bulbous and quite shapely. As she made her way along the street she was enjoying every little blubbery bounce it was giving behind her making her enjoy the walk even more. Her flank was at least double the width of her back, if not slightly more. It was almost hypnotic, stallion’s heads snapping towards it as if it were a magnet that was pulling their eyes towards it, all absolutely transfixed on her huge rolling rump that bounded up and down as she glided by them. She was loving the attention, more so than usual. It was a different kind of attention, one she had not experienced in years, and why she kept making these morning trips out to the populace.
She finished her jaunt and approached the entrance to the castle. A guard opened the door and she squeezed her way inside, gigantic tush rubbing against the doorframes as she did so. She was inside the castle and had spotted her prey, one of the many guards that patrolled the halls. Nopony else was around, it was the perfect opportunity. He was clearly distracted by some thought or another, and as quietly as she could she approached him from behind and turned herself so her butt was as close to him as she dared. He had no idea what joyful surprise the princess was about the thrust on him.
“Excuse me, guardspony?”
As he turned he was confronted by 500 pounds of towering ass that came far above his head and he looked upwards to see her raise her tail just in time. His “Yes Princ-“ was cut short as that huge fatty white flank came crashing down upon him with the force of a jackhammer.
The poor guardspony, Celestia wasn’t usually so forceful but she hadn’t had a good facesitting session in a while, and was particularly pent up this time. Her royal flank was also gasping for it, just like the guard who was buried beneath hundreds of pounds of ass. She grinded into him just a little and then let up slightly so he could recover from the sudden darkness that had come covered his entire face.
“I’m sorry, what was that?” She cooed as she raised herself slightly so he could gasp for air.
“mmmfff, mmff fffmm mfff!”
“You want more, and harder? Oh my dear guardspony, I’d be happy to oblige.”
Her full force went into the next enjoyable rub against him. Celestia let her full weight onto his face as she spread her legs apart slightly so she could really wedge him between the two massive wrecking ball-like globes that adorned her rear. She felt his entire head slip between her and she worked that massive booty on the guard below her. She glanced sideways and took stock of herself, her sun cutie mark was wobbling around on her thighs as she bounced her butt up and down onto the guard who had stopped protesting at this point, consigning himself to having a huge white rump repeatedly smooshed into his face at the full force the princess could manage. She raised her rump once more so he could at least hear the next command.
“Now I’ve done something for you, do something for me. I’d start working that perfectly good tongue of yours on the double soldier.”
“mmmmfffffff hhhhmmmmmm.” Which sounded like agreement, at least to her.
As she lowered her ginormous butt once again she felt an intoxicating wetness as the guard went to work, licking away at her with all he could muster. Clearly he had had some practice, as she felt him go straight for the most sensitive and enjoyable spot. She let out a moan of enjoyment and rubbed her lardy flank harder into his face, grinding down into it with all her might. Embracing the situation further the guard, up until this point splayed out on his back on all fours, raised his hooves and put one on each flank and started to rub them while Celestia continued to enjoy herself. She was groaning and moaning with each rub on her flank as the guard also continued to lick away at the huge booty covering him.
Before the inevitable end she decided to give him one last little reward for taking on such a mammoth task of satisfying her ever growing buttocks that were enveloping his face. She had been practicing with pillows in her bedroom and thought herself ready now that her butt was big enough to try it with a real stallion.
With all the force she could muster she clamped her mountainous cheeks onto his face as hard as she could. There was a little yelp as the guard felt the full force of 500 pounds of ass solidify around his head. With all her might Celestia stood up from her previous sitting position, flank now raised gloriously high in the air behind her, the guard hanging from her rear and gripping her round blubbery butt as tight as he could to stop from slipping out.
She was lucky she was near a wall, as she turned 90 degrees and backed up towards it. The guard came into contact with it first, and then her two colossal, swaying cheeks were pushed as hard as she could into it. As she did so they spread further outwards, really allowing her to make good use of it. She was panting hard as she worked her butt against the wall and continued to pleasure in the feeling of her massive flank rubbing against it, all the while the guardspony continuing to lick away like a champion. She was wet, sweaty and about to finally climax all over the wall and the guardspony still wedged between her jiggly round cheeks.
“You’ve…ahhhhh…been so good so far…ohhhhh…but I’m afraid...eeeeeee…my loyal subject, it’s about to end – ahhhhhhhhhhhhhhhhh.”
The princess came with the force only a mare of her repute could muster, the rubbing on the wall, the incredible tongue action on her fat flank and her cheeks spread wide, she went weak at the knees as she released all her pent up energy all over the guard. There was a small gasp as he took on the sudden release and embraced it, giving a few final licks and squeezes of her cheeks as the now red faced princess panted and groaned, finally dropping to the floor and resting her immense body from the session it had just endured. She smiled to herself and enjoyed the feeling of contentment that was coursing throughout her body.
Behind her, the thoroughly abused guard panted and moaned as well, shaken up from the whole experience, he had clearly enjoyed himself as well – his uniform looking a tad…stickier down below. He lay on his back and let out a little “ohhhh.” as Celestia stood up and adjusted herself, looking over at him.
“Thank you..for that. Clean yourself up and clean up the rest of the mess we’ve made. Then take the rest of the night off. I think you’ve earned it.”
There was no reply from the still dazed and panting guard, simply a smile as Celestia turned herself around and made her way down the rest of the hall towards her quarters. Her mind wandered, how many more guardsponies could she unsuspectingly sneak up on and reward like that? It was an interesting thought, and with her blubbery flank she knew they would all come around just like he did. She was going to have to indulge herself a little more and really bulk up her behind, the bigger it was the more she could do with it and the more everypony would lavish attention on her. For the final time she grinned to herself, and disappeared into her room.
