A long time ago, I wrote a fanfic about a girl going to her boyfriend's birthday party to wish him happy birthday.
She was wearing a white sundress, white knee-high socks, and pretty black sandals. On her way to his place, she picked up a large, delicious chocolate cake decorated with swirls of pastry cream from a bakery. The road to his house ran through a small forest belt known for its dampness and swampiness. Staring at her phone, the girl didn't notice how the path abruptly turned against a cliff, which concealed a huge swamp beneath, covered in a multi-year layer of mud and overgrown with reeds along the edges of the bank. Stepping straight off the cliff, the girl miraculously managed to grab onto the roots growing out of the cliff, keeping her a few centimeters from the foul-smelling, black, sticky, and greasy liquid, into which her phone immediately fell. She had guarded the cake on the edge of the cliff, so it teetered on its very edge, threatening to fall right on the girl's head. Her strength was failing her, and the thin roots and loose cliff, generously showering her with damp earth from the rain, staining her curled hair, her white bow, her bare collarbones, her face, and part of her dress, prevented her from pulling herself up any higher. Due to the shifting ground near the cliff, the cake tore off the edge and fell right on the girl's head, shattering into drops of cream, chunks of delicious chocolate batter, and chocolate spread, smearing it all over her head, hair, face, neck, shoulders, and especially her décolleté. The girl held on with all her might, groaning in exhaustion. Meanwhile, the liquid chocolate syrup, laced with white pastry cream, had already spread across her flat stomach just beneath her white sundress, leaving a distinctive dark brown mark on the outside. It flowed into her lace panties and trickled down her thighs, past her knees, all the way to her ankles, and into her sandals. A few seconds later, a chocolate-cream-like substance began dripping from them, mixing with the green swamp mud below. Unable to hold on any longer, the girl let go of her hands and, with a loud, splashing sound, fell backwards into the swamp. Her sundress had airy decorative elements that immediately released a huge amount of air as soon as her head disappeared beneath the black liquid. Black air bubbles burst with a loud splash where she fell. Resurfacing, the girl struggled to find a long root hanging over the cliff and pulled herself closer to the shore. Her magnificent wavy hairdo and bow were destroyed by the stinking mud, now resembling simply a disgusting, black, shiny lump on the top of her head. Her long eyelashes, weighed down by the swamp mud, threatened to fall off. Having clambered onto solid shore, the girl no longer looked as attractive as she had when she began her journey to the boy--every fold of her sundress was now oozing fetid water mixed with silt and mud, leaving a distinctive muddy trail behind her as she trudged. Her sandals made an unpleasant squelching sound, but it was unsafe to take them off in the forest, so she held on until she emerged. Her crotch felt pleasantly cool, despite the unpleasantness of the situation on such a sweltering day. There was nowhere to wash off all this dirt, so she emerged from the forest and kicked off her ruined sandals, limping along the paved road straight to the guy's house, attracting the surprised glances of passersby along the way, perplexed as to where she could have gotten herself covered from head to toe in such stinking black liquid...
