Kingdom Hearts: Lightning Bud (Private)
 

Larxene and Marluxia stepped through a portal they had just opened up, making them return back to the Castle that Never Was. They had just completed a mission involving doing recon in Halloween Town, which wasn't exactly fun.
"God damn, that was boring." Larxene complained. "I almost died of boredom back there!"

"Larxene, you've been saying that all day." said Marluxia, a bit irritated. He brushed a few dead flower petals off of his shoulder. "Ugh! I hate Halloween Town, you can never get anything to grow!" he growled.

"How could anything grow there anyway?" Larxene asked. "It's always so dark and gloomy, and no sun at all.......hey, where is everybody?"

Marluxia looked around the halls. "They must be either gone on missions or busy creeping around a frozen sub-basement..." He got a sudden devious smile. "Oh, Larxy... I think I know just how to unwind."

"Do you now?" Larxene asked, grinning widely, knowing what Marluxia had in mind. "Then shall we go to my room, or yours?"

"Yours, my dear. You know how Daddy feels about little Lar-Lar drooling on his carpets." said Marluxia jokingly. All the same, he opened a portal up to the twelfth floor. "After you, mademoiselle."

"Thank you, uh....senor." Larxene said, lamely trying to mimic Marluxia's kindness.
Once stepping through, Larxene dragged out a bin from underneath her bed, and when she opened it up, she pulled out a thick, white diaper, with the Nobody symbol drawn on the front of it. Taking off her Organization coat, she asked, "Can Daddy diaper up Lar-Lar?"

Marluxia grinned. "Alright then. Time to get Lar-Lar's diaper on before she makes a mess." He pushed Larxene back onto the bed and slipped her clothes off. First one boot, followed by its match, then her socks. He shimmied off her pants and gasped in fake surprise. "What's my Lar-Lar doing wearing big girl panties? Naughty baby." He slipped them off and slid the diaper under her rear, powdering her with practiced movements. He taped the diaper up and tickled her slightly. "All better, baby?"

"Yes, Daddy! Tank oo!" Larxene cooed, giggling from being tickled. Crawling off the bed, she rifled through the bin until she found two things; a blue pacifier and a rattle. Shaking her rattle happily and sucking noisely on her paci, she stared up at Marluxia with adorable green eyes and a cute smile.

Marly smiled down at her and got on his knees next to her. "What do you have, Lar-Lar?" he cooed to her.
