Artwork by  sogemaji, commissioned by me

Izumi the Fennekin Thief belongs to me

---

This was intended to be a remake of an old quicksand commission I got years ago, but considering what kind of pic this is... I guess "demake" is more of a suitable word here? lol

Anyways, the picture in particular that this is based off was never posted onto my gallery (I think, can't remember), but it featured somewhat of an unfinished design of my Izumi OC. I forgot how I stumbled onto the artist for this picture to begin with but I decided to experiment with another 16-bit styled picture and put him in charge of remaking it—honestly I'm pretty impressed with how this turned out! Especially with the attention given to the background, the surface of the mud, and of course... Izumi's body proportions ;^)

It'll be a very long while before I commission another picture of this kind, but regardless, I'm happy with the result.

“Alright, that’s everything.”

Izumi smiled as she tucked away the last of the gemstones into her bag. The Fennekin always enjoyed these little outings, getting to collect gems. Some were meant to be sold, while others she would keep for her personal collection—but either way, today was a new adventure! She’d never been in this particular cave until today.
The downside of visiting a new cave, however, was finding her way back out of here. There had been so many twists, turns and branching paths, after what felt like the halfway mark to escape, her footsteps had seemingly disappeared. With nothing to follow but her intuition, Izumi gave a light shrug.
“Good thing I have all day, I guess. Let’s see...” She tapped a finger to her chin, mulling over the three paths in front of her.
With the left path having the widest amount of room to maneuver, Izumi ultimately chose it for her alternate. As it turned out, the path was wide for a reason: from all the water that had previously flown through this area. She walked for what felt like half an hour. Although it was only a small, steady stream of water, Izumi was confident it would eventually lead her to some sort of way out of the system of tunnels. What it led her to instead…

SPHLORPH!
“A-Aaah!!”
...was not an exit, but a modest room with a pit full of deep, hungry muck. It instantly pulled her right down to her knees, making her maw open in shock as she looked down at the wobbling, pillowy substance. With an exasperated sigh, she gave a soft stomp.
“Great... this’ll take forever to get out of my fur...” Izumi groaned, looking at the remaining distance until the tunnel shrank back down. “...I guess it’s not that far.”
There was always a chance an exit was just beyond this stuff. All she had to do was wade through the mire. One leg sloshed forward, then the other, feeling the goopy, thick texture graze against her legs. As she expected, the muck grew deeper as the Fennekin neared the center of the pit. Suddenly, the solid ground under her feet dropped, making her give a loud squeak of surprise as she sank until the mire was halfway up her thighs. It slowed, but even after the second deep plunge... Izumi continued to sink.
“Ugh, this stuff is just...”
The Fennekin looked down at the muck with a scowl. It lazily bubbled back at her, gently sloshing over her legs, splattering a bit more of her thighs. Blinking, her annoyed expression slowly melted into a bit of curiosity. It might have been thick and a bit gross, but it did feel rather nice as it rubbed her lower half.
“Mmm.”
Her legs continued to pump forward, but her pace grew slower and slower... not because she was stuck, but because she found her focus on the muck itself. It continued to slosh and bubble, rolling up her thighs as they were sucked deeper into the pillowy abyss.
“Huh... this might be... quicksand...” She mumbled, not a hint of fear in her voice.
By now, her thigh high boots were all but gone, and admittedly, the Fennekin was more than a bit curious to see how it truly felt on her fur. Watching the attire with a sparkle of excitement in her eye, Izumi continued the gentle slide downward until her boots were totally submerged.
“Ha-aaAAaah...!”

In an instant, the pillowy muck rolled right into her footwear. Not only was it a beautiful sight—seeing it flow into her clothing–it quickly began squelching and splattering against her feet, calves, knees and thighs. It’d make escape far more difficult, especially if she wanted to keep those boots, but in that moment, Izumi simply did not care. It felt too amazing... and she had to feel more of it.
Izumi felt her toes touching another drop-off. Even if she couldn’t see under the surface, her eyes were still glued to it. If she wanted to get out of this muck, she’d need to go around the side, but... something just told her to step forward and–
Blrphblk.
“A-Aaah...~”
The same reaction, but Izumi’s tone was laced with something far different than surprise and fear. Her eyes shone with delight as her body plopped right down to her backside, and moments later, it, too, sank into the wonderful cushion of quicksand. That moment settled it... and settled her into her new playmate.

“Oooh... n-no way am I leaving now...~” She cooed, beaming as she wiggled her sunken backside a few inches deeper. “Wow... I wonder if...”
Before she could finish her thought, her body acted of its own accord. It bounced in the muck, making the surface wobble as her hips slightly rose, then fell, sloshing up and down... up and down... and it was pure bliss. Izumi gasped in delight at the feeling of muck squelching against every curve and crevice of her body, sliding past her clothing with the ease that only quicksand could provide.
Blush rising in her face, and heat rising in her lower half, the Fennekin practically beamed down at the bubbling quicksand. “Mmmh, I take it back! I take it all back... I’m never letting you get out of my fur...”
It needed to get deep into her fur. Placing her bag of gems next to her, Izumi gently plopped one arm into the mud. It splattered a few flecks onto her stomach, making her gasp in surprise and approval alike. This muck was staining her white fur, but Izumi could feel the heat rising in her cheeks at the thought of it soaking her entire belly. If anything could, it would be quicksand, simply taking her bouncing body and splattering more and more of that warm, sticky muck against her belly until every last inch of her once pristine fur was soaked in the stuff.
Now that Izumi had completely plunged into the quicksand, she could feel how truly alive it was... and it was gulping & slurping down her body like a monster... a beautiful, amazing monster. She wanted it to slurp her down deeper. In her flustered mind, she wasn’t leaving this swamp until her belly was soaked completely in the thick, pillowy muck.

The second arm joined the first, now fully committed to the act of letting herself get as dirty as she wanted. If bouncing in this stuff with just her hips felt good, then using her hands for some extra leverage would be–
“O-Oohh... oh, yes...!” She tossed her head back and savored that beautiful, sticky feeling. “Mmm, forget the exit... this is what I needed!”
Gasping, squeaking and squelching, her body continued to bounce up and down, pressing hard against the surface and the soft resistance over and over. It cradled her rump and legs perfectly, like a lover who knew exactly how to hold her.
“Nnnh... gnnaah, ooooh... mmmf, haangh...”
She knew how to hold it, too, her digits gently squeezing the muck between them, legs shifting enough to do the same underneath the surface. This stuff was her lover now. Minutes went by... maybe even hours. It didn’t matter how long it had been. If anything, the gentle plunges up and down to really push that muck all into her fur, into her, was just a sign that when she did get out... if she got out... the right thing to do would be escape, come back with enough supplies to spend a week in here, and really let this stuff know how she felt about it. The feeling of her slim belly getting soaked in the stuff got her gasping in a way she never had before.
“Ooohh... d-devour me... please...”
A gentle clinking noise caught her attention, though barely.
“Nhhh, hhhah... mmph, ooh...~”
When she finally did bother to look over, Izumi noticed the bag of gems tipping over. She’d completely forgotten about them, but there they were. Several shiny objects began to plop into the quicksand, their beautiful luster marred by the creamy muck... just like her.
Those lucky gems, sinking all the way under...
Still, Izumi just shrugged, still bouncing as she gave a squeal of delight, then an equally excited gasp.
“Mmmm, yes... go deeper with me, too...” The Fennekin begged, feeling a particularly deep bounce splash a wave of mud a few inches higher on her stomach. “Yeaaaah... ooooh, yeaaah...”
Her bouncing grew deeper and thicker, as if her body was truly entwined with the quicksand. Deep down? She knew it was. Those gems weren’t so important now. She could find more later—the real treasure was this wonderful pit.
Glrph, blrpk, phlaph.
Perhaps it was time to stop bouncing her body and get out... after a few more hours.
“Mmmhhh... yesss...~”
