@Skyfall  
Marvelous story to a marvelous image…
 
Curious to know more about Skyfall’s history.

Please do not remove the tag “oc:skyfall” That’s this character’s name. Just because another OC shares it, does not mean you can delete it.

Serves you right for trying to mess with the changelings.

And, the story originally accompanying the pic.

One slip and it’s all over, they said. Skyfall never figured it would be literally. A rushed leap to the edge of a rockface to hide from her quarry had been followed by a trip over the side, and into a pit of this… stuff. She knew changelings would be difficult to track, more so to learn anything about, and even more so again to infiltrate, but who could be better up to the task than she?
 
Her legs hit the gunge first as it swelled from the walls of the pit, and gravity carried the rest of her down, to land on her back, legs still stuck at the walls. The impact to her back winded and stunned her. It was already too late when she went over the edge, but by the time she’d caught her breath and reacquainted herself with her surrounds, it was definitely too late. She could feel the cold slime creeping up her neck and sinking into the hairs of her crest, and her right arm, extended to catch herself, had already gone under. Her left elbow was covered, but her hand was still free.
 
Oh, what a day to be wearing her finest latex. It was almost a boast, that she could wander into the hive making full squeaks as she walked, and forcing herself to coo in dirty delight every now and then from how it tugged and stretched over her body, all without getting caught. But now, all it was doing was making the slime feel uniquely clammy and cold, sucking the heat from the sweat and lubricating lotion underneath, and pressing all around it. She blushed. At least it looked like nobody could see her like this. She didn’t scream or moan or cry for help. She was too well-trained for the former and too independent for the latter. Either way, her body privately betrayed the mix of alarm and lust swirling in her right now.
 
What even was this stuff, and where was it coming from? It looked and felt rather like that biological, mucosal slop the blasted bugs used to restrain their captives, just in excessive amounts. Maybe it was pouring out of the wall? Maybe they didn’t make it themselves, and just took small supplies of it from vats like this? If that was the case, then maybe she’d be rescued - by the last ponies she wanted to be rescued by.
 
She let off a short, breathy squeal. Cold slime entered her ear, reminding her that she was in fact in distress. Based on this and the slow movement of the bubbles, she figured that it was flowing, if ever so slowly. The amount of bubbles made her nervous. More bubbles, means lower density, means greater likelihood of sinking. She immediately began to tug on her arms and legs to try and get them free. All her limbs were encased up to the elbow and knee joints, making this an exercise in futility. All she managed to do was drive her body a little deeper, and wear herself out again. The latex of her coat and shirt fought her breathing, making sure to keep her breathless.
 
Maybe there’d be one last hope… she closed her eyes and held her breath, forcing focus to her horn, producing… a couple of sparks of nothing. She couldn’t form magical signatures - there was just nothing there. She could feel a trickle of the green glop running around the spirals of her horn. It would make sense for a restraining slime to have silencing properties… She gave another instinctive wriggle. A bubble burst next to her face, throwing some of the slime alarmingly close to her mouth. If she didn’t find a way out of this one, magic wouldn’t be the only way she’d be silent.
