Waiting for Frieren

Fern sat on a mossy stone just outside the damp, pulsating mouth of the cavern, her breathing still coming in ragged, uneven hitches that shook her entire frame. Her lavender hair was matted with a thick, translucent slime that shimmered uncomfortably in the pale moonlight, smelling faintly of ancient ozone and musk. She was wrapped tightly in Frieren’s spare traveling cloak, clutching the heavy fabric so hard her knuckles were white and bloodless, trying to hide the fact that she was completely naked underneath—the acidic, specialized secretions of the beast having dissolved her sturdy wool clothing into a caustic, steaming froth in a matter of seconds. "Mistress Frieren..." Fern began, her voice a low, trembling rasp that carried a mixture of residual shock and a deep, simmering indignation. She refused to look at the elf, who was currently preoccupied with shaking the lime-colored slime off a salvaged, waterlogged grimoire, looking entirely too casual for someone who had just witnessed a biological catastrophe. "It happened the second you stepped into that inner chamber without even a basic detection barrier. You were so focused on that 'secret chest' that you didn't even notice the mana-fluctuations shifting beneath our feet. A Tentacle... it didn't drop from the ceiling like a normal cave-predator. It surged from the shadows directly beneath the threshold. It was faster than any offensive spell I could formulate in my mind. It stripped me instantly—my clothes just... vanished. It felt like being licked by a giant, burning tongue." "Oh," Frieren commented, not looking up from her book. "That sounds like a Gastropod-Mimic. They have a very high concentration of gastric acid in their outer membrane. It’s quite rare to find one that large outside of the Central Lands. Did it tingle? Usually, the acid has a mild numbing effect to prevent the prey from struggling too much." Fern’s face burned a violent, pained shade of crimson at the clinical observation. She squeezed her eyes shut, the phantom sensation of the slick, pulsating appendage still echoing through her overstimulated nerves. "It didn't numb anything, Mistress! It was agonizing! It didn't want to consume me; it wanted to use me as a biological anchor for its internal circuit. For hours while you were deeper in those tunnels, chasing after some useless 'laundry-drying' spell, that thing held me suspended against the jagged stone wall. It was relentless. It forced itself into my Pussy and my Anus simultaneously, a dual, synchronized intrusion that felt like it was trying to split my very pelvis in half. The girth was... it was unnatural, Mistress. It was cold, rhythmic, and mechanical, stretching my frame until I couldn't even scream anymore, only gasp for air that smelled like rot." "Hm," Frieren hummed, flipping a sticky page. "The dual-entry is a reproductive strategy. It maximizes the surface area for nutrient absorption through the mucous membranes. It’s actually quite efficient from an evolutionary standpoint. I read once that elves have a higher tolerance for that kind of internal displacement, but I suppose for a human girl like you, the stretching must have been quite significant. Did you feel your pulse syncing with the creature's heart? That’s usually when the bridge is complete." "I wasn't looking for a 'bridge', Mistress! I was being dismantled!" Fern’s voice rose to a shrill, hysterical pitch. "I was a captive audience to my own violation! Every time I tried to gather enough mana for a 'Zoltraak' blast to free myself, the tentacle in my rear would pulse with a heavy, electric throb, sending a shock of localized paralysis directly through my spine. It knew exactly how to keep me helpless. I was being used as a vessel, filled and expanded until my abdomen felt hard and distended. I could see the shape of the appendages moving beneath my skin... it was horrifying. I felt like a discarded shell being prepared for a brood." "That would be the 'ovipositor' phase," Frieren noted, finally looking over at Fern with a blank, analytical gaze. "Though, since it was a mimic, it was likely just injecting high-density mana-fluid to stabilize your temperature. You’re actually glowing a little bit from the inside. It’s a very soft blue light. It’s actually quite pretty, in a way. You probably won't need a lantern for at least three days." "I don't want to be a lantern!" Fern shrieked, pulling the cloak even tighter around her chest, her eyes brimming with tears of pure, unadulterated frustration. "When you finally 'saved' me... when you finally realized I wasn't behind you and cut those things away with that lazy wind-cutter... I didn't feel relief. I felt hollow. I am completely Gaped, Mistress Frieren. My body won't close. I can feel the night air... inside me. It’s disgusting. It’s 'ecchi'. It’s the worst kind of despair a girl can face. I feel like a broken toy." "It’ll snap back eventually," Frieren said, turning back to her grimoire. "Human anatom
