Ambrosial Excretions

Twilight stood behind the large doors as Celestia gave her speech inside the auditorium, waiting for the signal to come inside and present herself. She tried to stand as normally as possible with the huge diaper rubbing against her. She desperately hoped she could hold herself until after the ceremony, but her hopes were not high.

She kept as still as possible, because every time she moved, the diaper rubbed over her nether portions, and it was much softer than she had anticipated to say the least. Twilight glanced nervously at the four mares and four stallions behind her, paranoid that they would notice how far apart she was holding her hind legs, but the enchanted royal gown draped over her behind seemed to work.

“Ready to go?” nodded a unicorn next to the doors.

Twilight nodded and put on her biggest smile as the doors opened and she looked into the auditorium. It was a large crowd, and the path from the entrance to where the princesses and her friends stood had never looked longer. She tightened her smile and stepped forward.

Walking was even more awkward, feeling all the eyes on her. Her hind legs splayed, hips aching from the odd posture. She now knew why princesses walked in what was often called ‘the royal prance’, but wished she didn’t. She supposed the high-society ponies would be impressed that she ‘learned’ it so quickly.

She could walk carefully before, but now she had to take large steps if she were to move quickly without galloping outright. The material was sliding against her vulva with each step, back and forth, tingling distractingly. She clenched her teeth; as if she didn’t have enough to worry about without also being aroused.

The ponies behind her sang as she pranced, but she barely heard them, too busy concentrating on not tripping. Her bladder also ached more the less she wanted to relieve herself, and the pressure kept building. Still, she was confident she could hold it a little bit…

Or not. She supposed Celestia wasn’t kidding about alicorns losing control; she'd been hoping that that took a while.

At first she continued to attempt to hold it in, keeping on her grin and trying not to tear up at the humiliation. Even if nopony in the audience knew, peeing herself still made her blush deeply, and she hoped it was mistaken for awkwardness.

The tiny spray of fluid spread warmly over her thighs and belly, wetting her fur before being absorbed into the magical lining. The warmth aggravated her arousal, and somehow the wet material felt better rubbing against her when damp. Her steps became unsteady for a moment and she stifled a small moan, thankful to the loud music covering the sound.

She teared up from her efforts to minimize it, but finally gave in, letting the shame wash over her as the urine washed out. More warmth spread over her thighs and matted her fur before being absorbed in the soft lining. She strained to keep the smile on her face as she walked. She finally stood in front of the princesses.

As Spike brought her new crown out on a pillow, Twilight grew frustrated and tried to squeeze out her remaining urine as quickly as she could while she wasn’t walking. Her brain rebelled at every push, but at least the humiliation of pissing herself in front of a clueless crowd of adorers distracted her from other nervousness.

As Spike held up the pillow, he glanced at Twilight’s backside. Knowing her well, he’d caught the awkward expression beneath the fake smile and knew what was going on. Finally as Celestia picked up the crown and placed it on her head, Twilight tinkled to a stop, a wave of relief settling over her.

She glanced back at her friends with a humiliated expression, paranoid that they noticed. They thankfully mistook the look for nervous affection and waved at her happily. Twilight smelled a whiff of fruity scent around her, and wondered how many of the three princesses had varying levels of deposits in their ‘collection units’.

Turning to the crowd, Twilight smiled and spread her wings out as she was supposed to, her diaper sloshing more than she expected. Twilight felt Spike discreetly move a claw up to check how tight the waistband was against her belly, but thankfully the elastic held. His claw felt better against her body than she wanted it to with everything else rubbing her behind.

The fact that he could still feel it with it being invisible made her more nervous. She would have to constantly worry about ponies bumping into her and feeling it. Maybe those that realized would pretend not to, but that idea made it worse because she’d assume ponies knew who didn’t!

This was becoming both the best and worst day of her life.

Next was the equally long walk to the balcony where she’d wave at the crowd, which thankfully put them further away from her. She breathed deep as Celestia knowingly patted her shoulder to comfort her, then motioned for her to go first.

The moist fabric clung to her flesh from her standing still, and now peeled off slowly as it began to brush over her most sensitive area again. It forced awareness of parts that she normally ignored during public interactions. Her marehood was exacerbating the situation by drooling more than urine thanks to the stimulation, and even her taunt anus flexed against the moisture.

But that wasn’t as bad as when she felt her bowels shift and felt pressure against that exit as well. Oh Celestia no, she had to hold it in! She wasn’t sure she could handle the humiliation of crapping herself in public on her first day on the job regardless of if those around her knew!

She made it all the way to the balcony, her hopes rising only to be betrayed again by her lessening control. As soon as she was about to open her mouth to start speaking, she felt herself give out completely. Rather than resist once it started, she hiked her tail up a bit and squeezed her stomach to take care of it quickly, hoping the diaper had sound dampening properties. Maybe she should have read the pamphlet.

Though the cheering crowd helped, she still heard gassy sounds as her bowels evacuated and the warm pee was joined by the less comfortable feeling of a solid chunk stretching her out and then smashing against the cushy fabric inside. She felt her stomach heave as the slime pressed down between her rump cheeks. It was still absorbed, but not as quickly as the urine.

Not only that, but it smelled, a putrid scent blowing up from behind her, making her gag a little bit more. Why did it smell that bad? Wasn’t it supposed to smell good? She glanced down at Spike in a panic, and he stood on his toes to whisper so only she could hear.

“The pamphlet said it’ll smell better when you follow the proper diet,” Spike whispered. At any other time such an absurd sentence from him would have made her chuckle, but now it just burned right down into her soul. Oh Celestia, her friends were right behind her! They could smell her more than anypony else here!

“Say something, Princess,” Celestia politely reminded Twilight when the new alicorn spent too much time waving awkwardly at the crowd with her increasingly mask-like smile.

Twilight felt her stomach stop heaving quite so much though, as if Celestia cast a spell to settle it. That was good since vomiting would be a lot harder to hide.

She kept her tone even during her speech, trying not to move as another squishier chunk exited her tailhole, hind legs twitching as she searched her mind for what to do. Finally she turned a bit and motioned for her friends to come forward to stand next to her so that they wouldn’t smell it quite so much. None of them showed any sign that they’d noticed, and perhaps they had no reason to think it was her, but she knew they’d figure out eventually and that was enough.

It seemed her rear end was done, finally, but she felt the diaper sag slightly. She really hoped that was enough to warrant a change. She flushed more when Spike discreetly felt up under her dress again and patted the crinkling bottom, and she realized he was checking it for fullness. She couldn’t imagine what ponies would think if they saw Spike periodically appearing to grope her.

He pulled his claw back and gave her a thumbs up as if to say it was fine. It was not fine, but at the very least, she could count on it not feeling quite as good on her marehood as before.

Or at least she thought. As she turned to exit the balcony, politely motioning her friends to go in front of her, she felt the gunk in her diaper squish against her nethers. The diaper’s material kept in heat well, so it was warm and toasty, and aside from the smell actually felt wonderful squishing around her pelvic fur. She now wished that Celestia hadn’t settled her stomach so it would at least counter this a bit.

This was going to be a longer event than she thought.
