The demons of the pit had much practice at torturing, tempting and tormenting human souls, so it came as a shock to them when they realised that, in the last few hundred years or so, humans were starting to effect them. No longer was it enough for the beasts to haunt, to harken to the delectable taste of a guilty conscience or a desperate man at his last ebb and watch as the threads of damnation they wove spooled out before them. No. Instead, they had taken to assuming corporeal form, to walking amongst the humans, feeling what they feel beneath the fabric of their skin and striving to understand what drove them in an increasingly modern and irreligious world. But that's when things started to change, when demons started acting strangely and abandoning their infernal pursuits. When they realised, somewhere in the recesses of their subconsciousnesses, that the hell on Earth they strived to create was more comfortable than the hell to which they were condemned. So they stayed, blending in as best they could although, by necessity, never for very long.
One such demon now walks through a hospital's halls, his high heeled feet click clacking on the floor. He hasn't started to smell yet, but already the itching is becoming too much to bear. The costume is of a nurse, a shapely, lovely thing that the demon relished in peeling apart, layer by layer. Oh, the noises she'd made as he separated flesh from bone, it played in his head over and over, each note of pain like a grand symphony. The itching though, the terrible itching that never leaves. For you see, no matter how hard a demon tries, no matter how easy it is for one to steal a human's form, to quite literally slip on their skin and walk a mile in their shoes, there's always something in the air or on the floor, something to get stuck between shoulder-blades or under the balls of their feet. Little, insignificant motes of dust that prod and torment every stolen second of every stolen day beneath the demon's new skin. But this demon is clever, this demon has an idea of a place to acquire new flesh that should be free of dust and other airborne debris. So he click clacks down the corridors in his stolen body, hips swaying as he opens the door to the maternity ward.
He find what he's looking for, a roomful of the snivelling young ones, all small and pathetic as they scream their helpless desperation and defiance at an uncaring world. He slips in the door and closes it quickly behind him, hearing the hiss as the door locks tight, hermetically sealed. He browses the stock. Too chubby, too ugly, too pale. Ah, perfect. He finds what he's looking for and allows his skin to fall away. The comely nurse crumples, leaving beneath the demon and the iron tang of blood in the air. The baby stirs as the infernal monster hovers over it, but it does not cry out. The demon picks it up in clawed hands and squeezes the life out of the tiny thing. Once it has stilled, he brings his foreclaw to the back of its neck and makes the incision. With probing fingers, he digs out the innards, making space for his infernal essence. They drop sloppily on the floor, next to the rotting husk of the nurse he'd borrowed. Eventually, the skin is hollowed out. He puts it back in place in the crib and readies himself for what's to come. With careful concentration, he wills his form into the vacant costume, feeling it come to life as his essence fill up the empty space, breathes infernal life into the shell of what once was. The door opens and another nurse walks in, letting out a blood-curdling scream as she sees the horror of skin and bone and flesh pooled upon the floor.
Others rush over and gawk and stare, but it matters not to the demon, his task now complete. A new body, one free of torment that he can live in for many, many years! But what's this? As he writhes about his cot, this new body woefully infirm, he can feel it beneath the skin of his face. The baby's wails reach a new crescendo as the demon howls its anger. He'd been so careful, but still a fleck of something sits beneath his flesh, the skin already growing angry and red as he rubbed and rubbed at it with tiny, awkward little hands. Then he notices another, above the child's left ankle, and another, right above his sternum. Rage wells up in the demon. The room was supposed to be sealed! Nothing could get in or out...unless the dust was already in here to begin with, or perhaps had travelled in with him upon the nurse's shapely form? He wailed then, louder than ever before, and the people stopped their crying and arguing to stare and the small bundle of anger and pain in the cot before them. The demon couldn't take it any more, he had to leave. Right now. And with that, the baby's screeching became unbearable. People cowered, covered their ears against the assault that then, suddenly, stopped with a loud, wet popping sound and a haze of liquid in the air. They looked up at the cot, now definitely empty of anything that could be called alive.
