The astrologist, Mona Megistus

A high, refined voice muttered quietly to itself while its owner stomped across the field. "Calla lilies, calla lilies, where are the calla lilies..." Under normal circumstances, the great Mona Megistus would never lower herself so much as to go digging through nature to find a bunch of flowers, but alas, these were not normal circumstances. For not the first time in her life (and it was unlikely it would be the last, either), she had spent what was SUPPOSED to be her rent money on another book on astrology, leaving her scrambling to make a little bit of extra Mora at the last minute. Luckily, a short trip to the adventurer's guild solved all her problems, as she quickly found a request asking for someone to deliver a bunch of calla lilies. It was easy, paid decently enough, and best of all, so simple she wouldn't even be tempted to try using her astrology.

In the faint distant, Mona saw a lake she knew to be a prime growing spot for the flowers she was after, and her pace quickened, her golden heels stamping into the dirt with every step while her short cape flowed behind her. As she approached the shore, she immediately got to work, crouching over and beginning to scour the mud for any and all calla lilies she could find.

She didn't even notice the center of the lake bubbling slightly, nor did she notice as a pair of pure white eyes set in a dark blue 'face' rose from the water to stare at her.

As established, slimes are primarily motivated by their hunger for elemental energy. And there is perhaps no greater source of such energy than those who hold Visions, those divine blessings that allow people to manipulate the elements at their whims. So when the Hydro Slime felt Mona, a Hydro Vision holder, approach, it was of course immediately attracted to her. It didn't have anything you could call a stomach, and yet a hunger all the same pervaded its form, driving the slime to drift through the water and towards the shore.

Mona didn't notice, partly because the slime was so silent, and partly because she was so focused on her task. She had gotten down onto her hands and knees to begin pulling calla lilies out of the ground, causing her black tights to cling even more to her shapely rear than they usually did, while said rear itself was (inadvertently) thrust up into the air in a rather enticing manner. In that moment, the slime was subjected to a view than a great many men would kill to catch a glimpse of.

The slime, of course, did not care for the view. Its only focus was on the great amount of elemental energy it could feel, practically rolling off of Mona in waves. It was beyond tantalizing, and as the slime finally drifted to shore, it immediately bounced closer to the astrologist, gazing up at her rear with wide, blank eyes.

It cannot be stressed enough that slimes do not have minds. Their only desires in life are to continue their own existence, and to consume as much elemental energy as they can. So not only do they not understand the concepts of perverseness and lewdness, but they entirely lack those concepts to begin with. This is all so you can understand that when the slime leaped up at Mona's rear, it was not for the same reasons you and I might do the same; the slime was simply taking what seemed, to it, to be the most direct route to get more of the elemental energy it so coveted.

Mona felt something heavy and wet slap against her ass and immediately turned to see what it was. "What in the world...?" Upon seeing the slime bouncing on her ass, her expression soured slightly. "A slime? Get off me!" She shook her body, sending her cheeks jiggling, but the slime managed to hang on, even as her movements grew heavier and more frantic.

The slime could tell that she was trying to get it away from her elemental energy, and it could not allow that. Its grip on her tightened, its gelatinous body beginning to sink through the fabric of her tights and leotard alike to brush against her smooth skin. It was then that it became distantly aware of a hole, or perhaps an entryway, into Mona's body practically right next to where it had landed on her. Slimes do not have minds, but if this one did, it is likely its thought process in that moment would have been something along the lines of, "She cannot shake me off if I am inside her." Hence why it began surging towards Mona's asshole.

The feeling of the cold slime against her skin had made Mona's sour expression shift into one of full-on rage, but when that same chill began creeping towards her lower entrance, she froze up. "W-What are... N-No, don't you dare...!" Her pleas went unheeded as she felt the slime part her tight pucker and begin to flow inside. "Nyoooo, stop!" Mona's body went wild, the astrologist seemingly doing her best impression of a bucking bronco in her efforts to dislodge the slime from her, but all she ended up doing was goading the slime into speeding up.

Its gelatinous body was able to easily flow into her, stretching the tight, fleshy walls of her ass and filling it to the brim. The sensation was almost painful, but whatever discomfort might have been caused was dulled by the slime's cool, soft skin. And the deeper it went, the more it could feel Mona's magnificent elemental energy, which fueled it to continue its perverse quest.

Mona grit her teeth, the beginning of tears bubbling up in her eyes. It was not that the slime's invasion was hurting her, far from it- she found it surprisingly pleasurable to have her ass filled to the brim in such a way, the slime diving into her and exploring her guts in a way she knew no man, no matter how worthy she might have found him, would be capable of. But therein lied the problem: she was enjoying this. She was enjoying being humiliated by a common monster- and make no mistake, this was humiliating for her. She had a reputation to uphold! If someone came by and saw her being buttfucked by a slime, then nobody would ever take her seriously again! She needed to put a stop to this before such a horrible thing could happen!

Lifting her rear a bit higher into the air, Mona propped herself up as she prepared for what she was about to do. "Get," she began, her voice a low growl. "Out." She brought her hip down and tot he side, slamming it into the ground with as much **** as she could muster. "Of." She raised herself back up. "Me!" And slammed right back down, this time even harder. She continued again and again, hoping the repeated hip drops would be forceful enough to dislodge the slime from her rear, even though each attack sent more and more pain surging through her.

To her credit, her plan did work. The slime found its grip on Mona's inside loosening, and it even began to fall back out of her. But just as quickly, it found its proverbial foothold again, gripping onto the inside of Mona's ass twice as hard and continuing its invasion twice as fast. It had found a veritable treasure trove of elemental energy (not that it knew what a treasure trove was), and the only thing that could stop it would be if it was killed. It wasn't terribly long until the last of the slime surged into Mona's ass with a lewd 'slurp!', the astrologist's rear subsequently returning to normal with a light clap.

As the slime found its way fully inside her, the last of Mona's strength left her and she collapsed to the ground. Panting heavily, she managed to flip herself over, lying on her back and staring up into the sky. She could feel it moving around inside her, that damnably perverse slime slipping through her guts and organs as it explored her body. She couldn't begin to understand what it wanted, she had never heard of a slime trying to invade someone's body before, and in her current fear-and-pleasure-wracked state, she just couldn't make the dots that danced before her eyes connect.

Wait, dots? Mona blinked, thinking it was a trick of the light, but indeed, there seemed to be a large cloud of dots dancing before her. Another blink, and not only had the cloud grown larger, but the edges of her vision were growing darker. "Oh... That's what... this is..." She mumbled quietly to herself, her voice lacking the strength to reflect the panic that was creeping up her spine (or was that the slime?). "I'm... losing... consciousness..." She didn't want to, of course. She was terrified out of her mind at the thought of passing out in the middle of the wilderness. She hadn't told anybody what she was doing, since she had thought this would be an easy mission, so who knows how long it'll be until someone goes looking for her? Not to mention the slime still working its way throughout her body. But her body simply lacked the energy to put up any sort of resistance, and what little energy it had was rapidly slipping away.

Faintly, Mona stretched a hand above her, and managed to grasp hold of one of the calla lilies she had already plucked. "I just... needed... some Mora..." And with those final words, Mona's eyes fluttered shut as her mind drifted away, leaving the slime free to continue whatever was about to happen...
