Cheating the Cycle of Life- A Padded Pony Collab

When Onyx woke up again, he was feeling feeling coldness on his belly.

"What is going on?" He muttered to himself, as he fluttered his eyes open. He saw in the dim light that he was strapped to the changing table by several layers of ropes and chains, and that his tail had been nailed onto the table.

"Hey! What's going on here?"

"What is going on is that I am going to punish you," Rarity said, as she opened the door with a creak, bringing in more light and revealing that she was holding up with her magic a couple of pill blisters. "You have been a bad colt again, and I think that it is time to raise the level of harshness of my punishments!"

"What?!" Onyx said, wiggling in his binds and making them move, but not quite managing to move around freely "But I've saved..."

"It doesn't matter, the police forces could have handled it just as easily without your help," Rarity said, as she popped one of the blisters, revealing a glowing red suppository "It's time for me to teach you to never, ever use your power again until you at least are partially legally responsible for your actions!."

Onyx, startled, started to struggle harder and faster, feeling pain his tail as he pulled out some strands and as the chains and ropes surprisingly resisted to his super strength. Rarity smirked, as she pointed the glowing red suppository and turned it tip-first towards Onyx's little butthole. He started to squirm and shake even more, the ropes squeaking and the chains rattling against the table as he did so.

"This will teach you!" Rarity said, as she then quickly pushed the suppository inside Onyx's ass, causing him to yelp in pain, as he felt his strength slowly go away and his powers waning.

"N-no..." he muttered, as Rarity chuckled and undid the ropes, leaving Onyx with only the chains onto him.

"Well, now that this is done," she said, as she threw the ropes in a corner and grabbed a diaper and some powder from underneath the table "let's get you re-diapered."

Onyx let out a whine, as Rarity quickly taped a light blue diaper over his crotch, just before undoing the chains and taking out the nail in his tail as well, and then putting him on her back.
