Cheating the Cycle of Life- A Padded Pony Collab

"Ugh... what happened to me last night?" Soarin' said, rubbing his forehead, his body aching all over "I feel as if every bone in my body broke."

He painfully got up and fluttered his eyes open, revealing to himself the presence of a pink blanket over his lower body and giant bars surrounding him. Soarin' immediately pulled away the blanket in surprise by turning around, thus making a loud crinkling noise which got his attention. Turning his head around, he saw a big, poofy, pink diaper with butterflies as pattern and purple leak guards.

"W-what?" he muttered to himself, as he turned around again and then got up on his fours "This makes no sense! I never signed up for that 'private club' Spitfire keeps blabbing about all the time!"

"Actually, you did." A robotic voice said from... somewhere. Soarin' jumped up and fluttered his wings startled, before sharply turning his body towards the most likely source, the ceiling, and snarling at it.

"Who the hay are you?"

"I'm Robonanny 3.5, programmed to take care of sissy babies like you. Oh, and fix gender dysphorias in stallions free of charge." The robotic voice said, oddly for a machine, with a somewhat snarky tone. Sorain' tilted his head.

"I'm neither, so please get me out of here."

"You're neither?" the robot said "you signed the waiver stating that you were aware of what you were doing last night. and, besides, I think it's a little too late for go back."

Soarin' looked puzzled at the ceiling still.

"I still don't get it." He said.

"Look in your diaper," the machine stated. Soarin' wasted no time in  doing that, as he sat down with a crinkle, moving the diaper’s hem away, to reveal something he wished he'd never discovered.

He lacked of his sheath and of his balls. In its place, there was a fresh-of-surgery mare's genitalia that, safe for the stitches, could've passed as the deal deal.

Soarin' cry of despair and rage could be heard all over the Kingdom of Equestria.
