She removed her pinny and placed it carefully on a desk in the corner. She made sure that all the cleaning goods were out of harm's way and then she stepped onto the blue sheeting, inches from the huge puddle of gunk that had been left for her to clean. She could feel her heart racing at the idea of what she was about to do next but noticed just in time that her weight on the plastic was just enough to make the puddle begin oozing slowly towards her. She had been about to step into the mire but now, she thought, it might be more fun to let the mire come to her.
Sam was eager now -- her initial reservations completely dissolved. She watched with baited breath as the thick puddle crept slowly towards her dainty, red-nailed toes. She closed her eyes as it finally reached her, washing over feet and immediately saturating her tights. She gasped again. It was like nothing she'd ever felt before -- thick, unrecognisable goo seeping through her tights and utterly coating her pretty feet. She stamped gently, savouring the feeling of the slop moving around, squelching beneath her. Her whole body shivered with excitement and the juvenile naughtiness of it all. This wasn't supposed to happen but now that it was she didn't want it to stop.
As the puddle started to reach the ends of the plastic sheeting Sam realised she had to do something about it. Clearly there needed to be more weight in the centre so that gravity would pull the slop back in that direction. There was only one thing to do, Sam realised, stepping into the centre of the huge puddle with a huge grin on her face. The slime started to recede and Sam found herself standing in a much deeper puddle, much less thinly spread. It covered both her feet completely. She wriggled her toes to get the muck in between them but as fun as it was to coat her feet in slime she knew she wanted more.
Almost without conscious thought she began to lower herself till she was crouched over the yellow-brown puddle. Her bum was an inch away from the surface when she realised that her skirt was in the way. She was too in the moment to stop and take it off properly, so she paused for a mere moment to hike the hem up above the waistband and expose the seat of her tights. She immediately sat down heavily into the puddle, purring happily as the gunk began to seep through the nylon. It coated the backs of her shapely legs and seeped into the back of her knickers. Sam was in heaven.
She wriggled on the spot, almost involuntarily -- she couldn't help herself by now. Seconds later she found herself scooping up handfuls of mess and smoothing them over her thighs, making sure the fronts of her legs got covered too. It was as if she was luxuriating in warm bath -- she lifted her right leg, pointing her toes to the ceiling, and let slime fall from her cupped hands along the entire length of her well-toned leg.
Still, something was missing. Sam knew what level she was enjoying this on but she wasn't ready for that just yet. She wanted to ruin herself completely before she finished up here. After all, it wasn't likely she'd get another opportunity like this. As she lay back into the slime she knew what it was: her back, and her legs were completely drenched but her front was nearly pristine except for a few bits of collateral splash damage here and there.
Easily solved, thought Sam, rolling over like a happy pig in the thickest mud. The slime was in her hair now as well and it splashed out in all directions as she turned onto her stomach, splattering the walls, but she was long past caring about that. Now it seeped through her uniform issue white t-shirt and pressed against the caramel skin of her flat stomach and chest. A 32DD bra protected her breasts from getting to slimy but Sam soon saw to that. She rolled over again, the flimsy t-shirt matted, clinging to her chest, and sat up. Reaching behind herself, it took just a moment to unfasten her bra and fling it to one side. The t-shirt, she left in place, however. She looked down at herself and loved the way the cotton clung to her breasts, accentuating her natural curves and highlighting her jutting nipples.
After a moment's admiration she rolled back onto her front and sunk her breasts into the gunk once again. This time, with no bra in the way, they were soaked completely. Her saturated t-shirt offered no protection. She wriggled and writhed on her front now, shifting the slime around, playing in the mess without a care in the world. Finally, a little awkwardly, she reached a hand between her thighs. Still on her front, she shifted her hips up a little so that could reach inside her tights and knickers. This in turn forced her face into the slimy puddle -- something she had so far tried to avoid. But having her features completely obscured, feeling the clinging gunk on her face pushed her over the edge. She had been holding off her gratification as long as she could but it was time for the dam to burst.
Normally Sam could spend ages teasing herself but right here, right now she needed to cum. Her fingers moved easily over her clitoris. The slime was thick and sticky, but also viscous and worked excellently as lubricant. She rubbed it vigorously with two fingers, breathing heavily and noisily. Face-down in the slime, she used her left arm to support her body. It didn't take long in the state she had worked herself into. Her whole body soon tensed and she let out one final gasp as she peaked. Her fingers continued on, pushing through the waves of pleasure until, finally, they subsided and she allowed herself to slump forward into the puddle once more.
Sprawled face-down in the sticky puddle, it dawned on Sam that she still had to clean this all up. On the other hand, nobody would be here till eight in the morning and it was just hitting ten now. She decided she had time to bask in the afterglow and enjoy the cool stickiness of her surroundings for a little while longer. She rolled over onto her back one more time and simply lay there, almost perfectly still, slathered in slime from head to toe. She only hoped they had shower somewhere on-site.
