Miraculous diaperbug (Private for me and Diokno44)
 

Marinette slowly opened her eyes and realized she wasn't where she had been anymore. Her new surroundings confused her for a moment. "What the? Where am I?", she tried saying out loud but it all came out muffled, which was when Marinette realized there was something stuck in her mouth. Something she wasn't able to just spit out like that. It was a pacifier, fastened around her head like a gag. It took her a few moments after that but the full situation finally sat in. She was inside a crib, but it had bars on top, so she couldn't climb out. Her hands and feet were clad in mittens, rendering them useless, and worst of all, she was wearing a baby diaper. She sprung up and started shaking the bars, screaming for help, as loud as the pacifier allowed.

"Hello there baby Mari." A smooth, synthetic voice cooed. Out from the doorway, stepped Antibug. Her skin was a bit paler, and a ring of black rimmed her eyes. She was one of the copies of previous villains created by Duplicitaus, an Akumatuized photocopy salesman, who made copies of former villains. He had been defeated, but one of his copies had escaped

"Antibug, what is she doing here!? I thought I defeated her", Marinette thought, "Anyway I gotta get out somehow."

"Let me out!!!", Marinette screamed through her pacifier hoping it would do something.

"Aww, you're so cute when you're angry." Antibug cooed, pinching her cheek. "Now, does someone need a diapee change?" she squeezed the diaper

Marinette couldn't believe what was happening. Looking around the room she tried to find a way of escaping or at least find Tikki so she could transform.

"What I'd never use this diaper, who you do think I am!?", Marinette said through her pacifier at Antibugs suggestion.

"Oh really?" Antibug smirked, rubbing the messy diaper. "Your stinky butt says otherwise." she teased

Marinette couldn't believe this. "Why are you doing this! Where is Tikki? Let me go!", she shouted glaring at her captor

"Oh please Mari, I'm just playing with my little stinkbug." Antibug cooed, bouncing her

"Let me go!", Marinette shouted at her. Being bounced around in her dirty diaper. She didn't even know how Antibug got her to poop herself while she was out. She was blushing hard as this was very humiliating for her right now

Antibug set her in a vibrating bouncer turning it on
