The slime snapped her fingers and the gap in her thigh zipped closed like nothing had ever happened, not a mark on her.
Astrid's face dropped in dismay as she realised that she was now entirely surrounded by the puddle of slime and with a very large monster in front of her which she appeared unable to actually damage.
"S-sorry?" she managed to choke out after a moment.
A giant hand whipped down and Astrid found herself lifted into the air even as the slime girl continued to bounce atop Fey.
"P-put me down!"
"Squee?"
"P-please put me down?"
The slime girls face lit up joyfully and Astrid found both hands wrapped around her waist holding her tight, then below something started to change. She looked with big round worried eyes as a spot above the slime girls clit began to bulge outward, more and more slime pushing and shoving free, taking shape growing and spilling forth. A thick, heavy ridged length, a denser blue than the rest of the slime girl, a massive ribbed cock even larger than Fey's and with a tip like a human's only with little nodules covering it.
Astrid stared down at it.
"Wait… you- you can't be serious?!"
The slime girl smiled happily and Astrid found herself placed over the tip, the thickness of it larger than one of her already very thick thighs, a mass that dwarfed her pussy.
"You can't! It won't fit!"
"Squee!"
SCHLORP!
"AAIIIIEEEEEEEEE!!!!!"
Astrid screamed as the slime girl exerted her immense strength and she was forcibly made to take the slime girls cock, stretching her cunt wide with its mass, her clit instantly popping from its hood as her labia stretched thin.
The minotaur looked down in shock between the semi-transparent fingers holding her to see a bump protruding from her stomach, the shape of the slime girl's cock defined by her belly.
"I-"
The slime girl dropped, riding atop Fey, and Astrid came with her, dropping down onto the slime girl's dick, an impromptu cock sleeve. She wailed as inches more was forced into her, pushing apart the fingers of the joyfully squealing slime girl with her belly bulge.
This went on for about a minute, the rhythmic bouncing of the slime driving between minotaur and centaur, roughly using them.
"We-were here to stop you! Put d-down my friends or e-else!"
The slime girl glanced down at Vivi who had stepped from behind a pillar, her sword held in paw then looked again as she caught sight of the trail of white tentacles squirming on the ground behind her emerging from her crotch.
The vulpine wiggled her hips. "S-stay calm Wummy, you can do this!" she whisper hissed out the side of her mouth.
The slime girl furrowed her brow then nodded in Vivi's direction. A tentacle rose up from the puddle and whipped toward her, eager to snatch her up into the air as the others. But then the glossy white tentacles snapped forward, moving so fast they could barely be seen. The white tentacles wrapped around the far larger blue tentacle and squeezed down on it, squishing it out in bulges between them. With difficulty the tentacles managed to drag the larger tentacle down to the ground.
"D-do it now! Now Wummy!" cried out Vivi as even more tentacles pushed free from her puss and latched onto the larger tentacle.
The white tentacles shifted and then they seemingly began to melt, slopping up against the blue, rolling outward until they encased the thing entirely. The blue tentacle became a glossy white as Wummy's tentacles seemed to melt over it.
This got a reaction out of the slime girl who jerked backwards, pulling the tentacle with her. Vivi was launched into the air with a scream as the tentacles coming from her pussy attached to the larger tentacle dragged her up with them.
The slime girl held up her partly whitened tentacle in front of herself, Vivi dangling below letting out yelps as she desperately grabbed at Wummy's smaller tentacles trying to support herself. The slime girl's gaze ran down her newly whitened tentacle length with increasing alarm as the white was now rushing down the length toward the base.
"Squee!" she cried out in distress. The large tentacle sucked back down, pulling back down into the puddle part of her body, Wummy coming with it. The white touched down, but instead of being pushed off as the tentacle disappeared into the puddle it instead Spread. White slime poured across the slime girl's body like a tide, sinking into her, absorbing her, the white rolled up to her sunken thigh and then started to climb.
This time the slime girl's "squee!" was a squee of pure panic and moving Astrid to the one hand she dashed her hand down trying to swipe at the white growing up her thigh, changing her. Her fingertips brushed up against it and then the white simply absorbed into them.
She snatched her hand back, but it was already too late, a patch of her hand was white and growing swiftly. The slime girl flailed, utterly and helplessly trapped as she was absorbed, her hips bouncing and wiggling wildly atop Fey as Astrid was shoved around roughly by the panicking slime girl.
Astrid and Fey cried out at the rough treatment and a spray of their fluids dashed from their cunts as they peaked. The slime girl hardly seemed to notice, already half her chest was white and it was growing up one side of her neck, higher, over her mouth, up to her head.
The slime girl suddenly jerked to a halt.
"Squee?"
She said.
Then again. "Squee?"
The second squee was at a slightly different tone than the first, as though spoken by a different voice. Then the two voices sang as one.
"SQUEEE!!!!"
