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

"Nggggh! What's this!?", Marinette moaned, feeling the pleasure vibrating through her. Getting turned on in a dirty diaper was a new low for her

However, Marinette was not to suffer for long. The door flew open, as Rena Rouge, Cat Noir, and Queen Bee subduded Antibug, who dissapated

It was too late for Marinette though who found herself already quivering and bucking as her eyes rolled back and she had one of her biggest orgasms ever in her messy diaper

Chloe giggled a bit, "You know mommy, I always knew you liked diapees." she smiled, a diaper under her suit. Adrian had quite a boner

Marinette's face was burning bright red with shame. "G-Guys it's not what it looks like... I swear! She made me do this! I don't like this at all", She stammered through her pacifier, still recovering from her orgasm.

"Its OK Mari, you don't gotta fib to us." Alya kissed her forehead, helping free her friend, and Tikki, who was stuck in a jar.

"Please, let me out of this thing. It's so disgusting, and it stink!", Marinette whined holding her nose, still not believing her friends were seeing her like this. Her face burned red with shame and humiliation.

Adrian cuddled his lover, kissing her

Marinette squirmed a little and winced when the cuddling caused the mess to be squished against her butt. "Adrian, what are you doing!? I need to get some clean clothes right now!"

"Sure sweetie." Adrian laid her down, and began cleaning her up

"Finally, I'm so happy to be out of this thing", Marinette sighed as Adrian cleaned up her wet, messy and cummy diaper. Though she was caught of guard when she was Adrian getting a fresh diaper for her instead of the expected adult garments. "Adrian what are you doing? Don't put me in another diaper, I'm a grown up, not a baby!"

"We didnt bring any clean panties for you, so until we get some...." Adrian gave her an apology smile

Marinette frowned at that excuse. Couldn't she just go pantieless under her ladybug suit, she thought, but she didn't get to speak her mind as Adrian was quick in finishing powdering her up and taping her diaper shut. "Let's get home quickly then", She said getting up and waddling awkwardly due to the thick garment between her legs, still oblivious to the fact that a good portion of the laxatives Antibug used on her still weren't out of her system.

Chloe, Alya, and Adrian escorted her home

Marinette was relieved to finally be home and looking forward to change into her regular clothes. She was sick of waddling around with this thing between her legs like a giant baby. But just as she entered her room and had some privacy a gurgle could be heard from her stomach and a wet fart found its way into her diaper. Marinette didn't even get a second to react after that as her body involuntarily started loading up the seat of her diaper with a stinky mess. Marinette quickly closed the door, "Dammit this can't be happening. This stupid bitch Antibug must've done something with me. I must change out of this thing quickly before anybody notices. Ewww, now my whole room is going to stink like that."

Tikki patted Marinette's head. "Maybe you should stay in diapers, until whatever she put in you is out of your system."

"Tikki? Not you too now... Come one, I'm not a baby!" Marinette took a step towards her closet, cringing as the mess in her diaper moved along with her. She took another few steps so she could finally access her adult clothes but she stopped dead in her tracks when she heard the door open behind her. She didn't have the courage to turn around and face whoever was about to catch her standing in the middle of her room, wearing nothing but a freshly loaded diaper

"Hey Marinette, need some help?" Alya smiled, transformed out og her costume. "Adrian and I checked what Anti gave you, powerful laxatives, like ones you'd need for a horse."

Marinette blushed. Being stuck in such a situation she was completely speechless, so she just waited for what her friends were gonna do or say further while she was thinking on how to react to this properly

"Should take a few days for you to dump it all out." Alya said, hugging her friend comfortingly. She laid hrr xown, and began to tenderly wipe her clean

Marinette blushed heavily. She couldn't stop her friend from laying her down. "Come on Alya, I'm not a baby, please don't put me in another diaper. It's out of my system already, I swear!"

Just then, an ominous gurgling issued from Marinette. Alya let tye used diaper stay on, waiting for Marinette to go

Marinette continued defending herself and would do anything to prove she was adult but her attempts were stopped when she looked up as her body instinctively hunched over and squelching and crinkling could be heard from Marinette's behind as her diaper expanded even more. She took a step backwards, not realizing she was now cornered. "Ew ew ew, please Alya don't make me wear diapers", she pleaded

"Mari, these sre only until your bowels problem settles." Alya swiftly hwd her changed

Marinette was paralyzed from embarrassment so she couldn't do anything to stop from Alya putting her on the ground and putting her in yet a new diaper instead of her normal clothes. She quickly got up and opened up the window in her room to try and let out some of the smell. "Alya, can I atleast get some normal clothes to cover myself up?", she whined

"Sure." Alya behan studying nearby

She opened her closet and she quickly found a shirt but pants were more of a problem. Most of her pants were skintight, and obviously wouldn't fit over her overly thick diaper. She eventually found some yoga pants that would stretch enough to cover it, but she blushed at how ridiculous her butt looked when she saw herself in the mirror. "Stupid antibug doing this to me making me have to wear diapers", she cursed under her breath

Adrian, meanwhile came to check up on his girlfriend

"Adrien, I hope you're not disgusted with me for this. It's not my fault, Antibug did something to me. I'm still a big girl!", She complained

"I know Bugaboo." Adrian held his lover close, kissing her passionately
