The Slime Girl.

Arthur pulled out of Mata, allowing his cum to flow freely down her legs into the puddle of the ooze below. The puddle shimmered. Mata planted kisses on Arthur’s chest. “Who was that?” Mata panted. “An ooze? I’ve never seen one look so human.” Arthur hadn’t either. Give her a name.

The ooze began regaining her shape. Looking up at Arthur, she began to flush back to her elfin disguise, and soon any hint of blue was undetectable. “Lexx” Arthur muttered almost too quietly to hear. Lexx began to pulse as the new name seemed to strengthen her, make her more real, define her and gave her shape. She steadied and beamed up at him with a million megawatt smile.

Arthur felt a bit weak, using a smile that cute should be considered a war crime. He mustered his defenses. “You ate my clothes. How are we supposed to get out of here?”

She turned back into a puddle so quickly that she seemed to vanish. Seeping into Mata’s sundress she absorbed everything from it then lifted it up and shoved Mata into it roughly, Mata struggled but Lexx wouldn’t have it. She was relentless. Then she began to climb Arthur’s legs. Similarly resisting any attempt to push her off. As strong as Arthur was now she just flowed around his hands, until he was covered completely by a blue layer which quickly darkened and changed textures until it looked like the clothes he had lost earlier that day, complete with flip flops. It still felt like slime.

This was going to take some getting used to.
