The band had no answer, none of their Skills or weapons were viable, it seemed they were doomed to fall prey to the slime, an impossibly strong monster.
That is until one of the tentacles accidentally touched up against the cummy mess that was Fey's under-barrel and back legs. She hadn't gotten around to cleaning herself from the mess made at the AG and her back parts were frosted in a layer of white.
The slime monster froze up, and then its main body seemed to slowly turn and stare at the centaur it held in tentacle.
"Uhm, h-hello?" said Fey, like a hare caught in the lamplight.
"Don't speak to the giant slime monster Fey!"
"I don't know what else to do!"
The slime touched up against her experimentally, drawing in the cum coating her fur, sucking it into its tentacles, tasting it. It reacted, the slime seemed beyond delighted by its discovery and a dozen more tentacles burst forth, this time all aimed at the unfortunate centaur who wailed in a panic as tentacles sucked and slurped over every inch of her body, sucking up every single drop of fluid on her and leaving her fur dry and clean in its wake. Soon though the slime ran out of cum and became frustrated, desperately going over every part of her looking for more, even pushing the tip of a tentacle into her mouth and puss in its exploration. Its movement became ever more frantic until as a tentacle curled around her three foot dick a cup of pre-cum gushed from the tip. The tentacles all immediately converged on the spot, practically fighting each other to get at the fresh source.
Fey groaned as so many tentacles squirmed and pressed against her cock and caused another spurt of precum. This seemed to confirm to the slime that this was indeed the source of its ambrosia and its tentacles suddenly changed, morphing together and creating a large barrel-like shape filled with squirming tentacles, a crude milking device.
"Wait! Fey! This is perfect!" shouted Flora, still struggling "You remember what happened last time? Your cum overloaded the slime and it tried to flee because it couldn't handle it!"
"What are you saying!" she groaned in reply as the tentacles inside the slime barrel began to shift back and forth, rolling down her length in long dragging motion, a sucking force simultaneously being applied as air was drawn out of the barrel.
"I'm saying cum in it like you mean it!"
"I- I don't have a choice! Oh gods this feels- this feels!"
The milking device rapidly sped up, a lurid schlurking queefing noise coming from it as the air was manually pushed and squeezed from inside it, the pressure ever increasing, the tentacles squeezing down harder and harder until Fey let out a shriek and spasmed in the tentacles grasp, her great strength causing the giant slime actual difficulty in holding her still.
Then she came.
The interior of the barrel instantly went white.
The giant slime monster let out an ear shattering "SQUEEE!" Of joy that left everyone's ears ringing and echoed on forever in the vast space, no doubt loud enough to be heard even on the surface.
The slime had found its ambrosia.
It just didn't expect so much.
It had all of three seconds to realise that it had made a mistake as white filled the barrel, forced itself through the tentacles surface and then exploded down the interior length of every tentacle connected to the milking barrel. Cum continued to pump and pump stretching the tentacles out as the sheer quantity of cum flowing into them strained them to the limit. The slime panicked, its tentacles flailing as an incredible amount of semen rushed down its tentacles and then burst into its own body.
"You did it! It's gonna run!"
"If I recall correctly didn't that particular slime evolve first before it ran away?" said Ellaria.
"It… wait, shit, it did do that, stop the cum Fey, stop cumming!"
"I can't stop cumming!"
"Do kegels, just stop! Oh my god that's so much cum!"
"I- cannnnn't It feeelss tooo gooodddd!"
As Fey's voice rose the slime suddenly began to emit a light, a light that grew brighter and brighter with every passing second until it filled Fey's eyes with a blinding white in which she could see nothing else.
The light faded and she blinked desperately, floaters crossing her vision as her eyes readjusted to the relative darkness. There was someone in front of her, right up close. She flinched back and it took a moment to realise that there wasn't actually someone right in front of her but there was someone further away, someone further away who was very very large and only appeared close due to her massive proportions.
The upper body and thighs of a girl stood where the slime had been, huge, over two stories tall, a vast slime person, her thighs connecting with a puddle of her slime that spread across the ground as though she was standing knee deep, the tentacles that held the band emerging from the puddles surface.
The giant slime girl blinked and held her semi transparent hands up in the air, looking at them with curiosity. "Squee?" she spoke.
"Di-did that incredibly powerful slime monster just evolve into an even more incredibly powerful slime monster from your c-cum?!" said Astrid, her eyes wide.
"D-don't panic! This might be a good thing! m-maybe?"
The giant slime girl turned her enormous head and looked between the members of the band and the minotaur with a curious light in her eyes. Then she tilted her head and smiled, her eyes closed. "SQUEEE!"
