It seemed as though the muck could tell what she was thinking, now past her knees and starting its work on her thighs. With the heat starting to rise in her face and between her legs from the realization, Ellie’s squirming continued, pumping her strong legs harder. Maybe it really was quicksand. Just like her shins before, each pull capable of lifting the Pokemon’s thighs brought a pillowy, reverse-cone of mud with it. The earth didn’t want to let go. Unable to keep one leg up without the other sinking faster, Ellie was forced to plop it back into the pit, grimacing as it sank back down… and then, even more.

Glrrrph…blck, phlp…
Oh gosh, that awful, sticky sound… she couldn’t help but gasp in shock and a bit of despair.

“Stop, please… I don’t want, nnhhh… to siiink…!” She grunted out the last word, giving one final, hopeful tug to her left leg… only to watch it plop back down, and slide in so deep, her backside was nearly pressing against the muck.
“Ohhh…!” Biting her lip, the Pokemon let out an annoyed whimper, looking down at the muck as it pulled her deeper. Fine… I guess I have to try…
Ellie didn’t like it, but even so, she pushed her right hand against the surface of the muck, forcing it as hard as she could carefully manage as her right thigh started to lift. For a brief moment, the extra balance of weight was working. The Garchomp gave a gasp of delight… but no sooner had she given the quiet cry of happiness…

Glorrrph!
“A-Aaah, no!”
Her thighs shifted, pushing her legs together a bit as Ellie caught her balance. The spot she was looking, however, was at where her hand used to be… now buried wrist deep in the muck, too.

“Fine… if I have to get my hands dirty, then…” She trailed off, now knowing what she’d have to do if there was any hope of wrestling her powerful thighs free of the thick, pillowy, creamy prison she was wallowing in. “...okay, here goes…”

The Garchomp closed her eyes for a moment, unwilling to watch herself do the unthinkable… but she did it. Ellie’s remaining hand plunged into the earth too, lasting only a little longer than her first as she leaned forward. Even before her eyes opened again, she could feel the last of her thighs sinking, but she wouldn’t let them go under! She couldn’t!
She gave a grimace, teeth bared as she leaned forward. Ellie felt that muck crawling up the back of her legs, trying to reach for her rump. No, it wouldn’t get her backside! Pressing harder into the earth, the Garchomp carefully pumped her legs up and down, trying to balance her weight on all four appendages now in the muck. It could take her wrist, even muddy up her thighs… but if it managed to pull her rump into its clutches, getting out would go from a tricky task to nearly impossible.
“Mmf…!”
Unable to think of anything else, Ellie tried bouncing her backside. It lifted up a bit, though it was hard to tell as it sank back down seconds later. Maybe doing that will work!
“Ungh…!” Another bounce of her shapely rear, then another, “...haah…!”
It was an odd feeling, using the weight of those curvy haunches and full backside of hers to stop the rest of her body from sinking. If there was anyone out there watching… her face went red at the thought. Still, she couldn’t just stop now.
“Mmh! Gnnh! Hhhff…!”
The whole thing was odd-feeling, embarrassing… but until her butt went under the surface, she would keep at it, trying desperately to think of a way to start getting out of this stuff!
“Gnaaahh…! Mmph…!”

Ellie could do this… she wouldn’t sink under! Even if it got her backside a bit muddy at the very top of her thighs, it hadn’t pulled her rear into the pillowy prison.
