Leela Fantasy Futurama.
Leela rose from the captain's chair of the planet express ship, cursing as she came into land and powered down its engines "Stupid assholes, can't trust any of em to do their damn jobs..." She grumbled, marching off the bridge and heading for the cargo bay.
Grabbing the package the crew were supposed to have delivered several days ago, but forgot, during a party whilst Leela was away. Kicking up a fuss, Leela kicked Fry and Bender off the ship, leaving them at a space port to find their own way home. She went back to drop off the missed package herself, unaware that a hidden danger lie in wait for her on the surface.
Lowering the cargo bay door she soon stepped onto the warm planet surface, stepping away from the ship she closed the cargo bay door and headed on.
After walking for some time, having landed as close to the outpost as possible Leela entered a thick wooded area, following a wide path that stretched through the woods. She began hearing faint whispers all around her, branches and bushes shifted occasionally, Leela stopped dead and drew her weapon, throwing the package under her arm "Who's there?? Whatever you are come out, I'm armed!" she barked, scowling as she looked around.
"Leela! Help me, please help me!" said a weak female voice, it sounded very similar to that of Amy Wong.
"Amy?!" surprised at how Amy could be here when she was supposed to be on Mars. Leela left the dirt track to follow the voice. Taking her off into the bushes in a thicker part of the forest.
Leela reached a tiny clearing, as she emerged she picked a few stray leaves from her purple ponytail. Ahead she saw what looked like Amy slumped against a tree, but she was covered in thick purple slime, in fact, she was nearly translucent, but still had Amy's overall appearance.
"Oh my god! Amy! What happened??" said Leela, running over to the slimy Amy-like formation.
"Help Leela... I need, I need..." the slimy creature's voice began to change, as did it's appearance "A host!" it snarled, lurching forward and covering Leela in its thick purple gunge.
Leela screamed, trying to fight it off but the slime simply covered her, wrapping around her body tightly. Pushing her down against the floor it began to ooze into her tight lycra trousers, sliding up her neck it soon forced it's way into her mouth.
"No! No!" Leela slurred as the thick purple slime quickly oozed down her throat, drowning her words as she unwillingly glugged mouthfuls of slime. Her lycra trousers stretched and grew as slime poured inside, filling out her body. She squirmed and fought for a while before she began to moan softly, enjoying the sensation of thick cool slime running down her thighs and legs, spreading thick slimy tentacles up into her slit.
The slime moved to start filling up her bra, wrapping around her nipples and beginning to soak it's way inside, filling her tits with slime. Leela lay squirming on the floor as the Slime filled her, her legs grew rapidly as her arse expanded with them, getting larger and larger every second.
Leela's eyes soon turned green as the Slime integrated into her body, blending with her mind and body to become one person "Don't fight me Leela! Just let me in, be one with me" said an unknown female voice. Leela couldn't help but give in, the pleasure was getting too strong to resist, moaning blissfully as she gulped down more Slime.
Her feet and hands began to move again as the Slime assumed control, adjusting to its new enclosure. Leela's white top stretched to its limits as the Slime filled up her breasts, turning them into huge fleshy orbs of wonder, ready to bury people's faces in them or stroke a large cock in her bra.
The Slime finished oozing into her mouth, allowing her to breath more freely and also moan more orgasmicly, with the rest of the Slime around her still finding its way into her lycra trousers, soaking most of it soaking into her skin to make her new size more permanent, once soaked into her body, it couldn't be removed.
Leela's eyes returned to normal before long, she gasped as she felt the Slime merge with her mind, blending their personalities into one, a new Leela was born, made from pure oozy Slime. Her arse grew as her lycra trousers soaked up the last of the Slime, giving her a very tall and plump figure, with curves of an Amazonian female warrior.
Leela came as the Slime stimulated her cunt playfully, letting out a huge climatic wail of ecstasy. The Slime that hadn't soaked into either her tits or her lower body remained sitting inside her clothing for padding, the rest was now part of her body, giving her a large curvaceous arse and hips, even without her Slime filled clothes.
"Ooh... Yes..." She said blissfully, closing her eye for a while whilst the Slime got settled in. Breathing heavily as she sat up, feeling her new curves, as well as the Slime squelching inside her clothes. Now in full control of its new body, the Slime made a few more adjustments before it was finished integrating.
Leela groaned uncomfortably as her face began to change, the Slime deep inside her body now able to alter her physical appearance, her large Cyclops eye gradually morphed into two separate identical eyes.
"God, my head!" She groaned painfully, feeling her face change. Her nose also changed size and shape, accommodating for the shift in her facial structure. Bones cracked and reshaped as two human eyes formed, complimenting her now radically increased dimensions.
Once done, Leela looked down at her hands, seeing the world just as everyone else saw it. She flexed her hands, feeling a new and ferocious strength within her, now looking down at her thick juicy thighs, rubbing her hands down them gently.
"Holy shit... What the hell just happened??" She asked herself, surprised at her new appearance so far "So full and squishy! I love it!" She cried, jumping to her feet, already noticing that she was taller.
She staggered for a moment once on her feet, adjusting to her new size, her arse and thighs made a good counterbalance for her breasts, gazing down at her body she squeezed her hips firmly, admiring their new look and feel. As she moved, she could hear the Slime in her bra and trousers squishing around "Hmmm, that feels so smooth... I can get used to this"
