My adventures as a humanoid slime girl and my encounter with the water witch.

The slime girl, Esper, a humanoid creature of amorphous visage, found herself standing opposite Nix, the Water Witch. They were in a secluded cove known only to the supernatural, its crystal clear waters acting as the perfect battlefield. Today was the day Nix had challenged Esper and mercilessly, she had lost. As punishment, Nix had decreed her to undergo the water blast, a unique form of discipline that meant being filled with water to the point of near-bursting. Esper, donned in a scant blue-green bikini that mirrored her translucent complexion, was situated in the shallows of the water. The cool waves rolled against her amorphous form and a breeze fluttered her slime hair. The anxiety was palpable within her as Nix raised her hands, the water around her swirling ominously. The first rush of water hit Esper like a punch, filling her body as if she were a balloon. Her bikini-clad figure began to expand, stretching the fabric taut against her growing belly first. It was a strange sensation, less painful than unsettling, as were the low gurgles that emitted from her expanded form. Tiny waves created before by the wind became vigorous under her inflations, their reflection glimmering over her skin, turning her into a living water nymph. Her cheeks were the next to inflate. The rounded masses swelled outward, turning her face comically large. She could feel the odd pressure, the strange fullness. Despite that, she never looked as shocked as she did before, and a half smile tugged at her lips. Her usually thin lips were now plump and protruding, making her expressions even more pronounced. Then, the water started filling her chest and soon her breasts stretched outward, transforming the initially meek bumps into two round globes. The sensation was overwhelming, foreign and invasive, but there was also something vaguely pleasant about it. The stretching of her now derriere, becoming softer, fuller, and disproportionately larger in comparison to her previous slim form, brought a tingling sensation to her body. Esper found herself unable to control the audibly resonating burbles, the water coursing through her making strange echoing sounds within her ballooning body. Each expansion of her form punctuated by a watery noise that mimicked a belly growl, adding to the weirdness of her situation. Her thoughts were muddled, a mix of bewildered amazement, humiliation, and a touch of defiance as she continued to grow, expanding until the draw of gravity caused her to fall backward into the warm, gentle waves of the cove. She felt uncomfortably bloated, yet there was an overwhelming sense of lightness too. The odd sensation of expansion and the persistent inflating continued till Esper felt as if she was on the verge of popping. It was oddly euphoric. Once she hit the capacity the witch had set for her, Nix, from her stance across the cove, giggled through her evident enjoyment. Proud of her victory and the humiliation she had generously afforded Esper. The tension between the two was palpable, but there was also an oddly misplaced camaraderie floating in the air. A ripple of laughter coursed through Esper, the waves cheerfully echoing her sentiments. Despite her predicament, she felt oddly...free. She was larger than life, a spectacle of her own making, filled to the brim yet buoyant in spirit. She knew Nix had intended this as a punishment, but in a strange, unexpected turn of events, it became a shift in perspective. It was then she realized that what was seen as a setback could be used as a stepping stone to grow, quite literally in her case.
