Yselle Side Story: The Grounding Rune
Author's Note & Disclaimer: Please note that the characters in these chapters are all consenting adults, and there is no biological relation between Yselle and Mina. Mina is the niece of Yselle's husband, Torren, making Yselle an aunt by marriage only. Yselle had no hand in raising Mina, nor was she a part of the girl's childhood or upbringing. Their dynamic is strictly between two adults who are navigating a new, consensual arrangement.
Yselle approached the iron doors of the Ash Forge. The rhythmic clang of a hammer striking heated metal, the sound she expected to hear echoing into the Tanner’s Wynd, was missing. The street outside held the noise of merchants hauling grain and the clatter of draft horses pulling timber, but the workshop itself sat quiet.
She pushed the heavy door open. The ambient temperature spiked the moment she crossed the threshold. The smell of burning charcoal, hot copper, and acidic flux filled her lungs. She closed the door, sealing out the winter wind and the gray light of the working lanes.
She walked past the cooling racks. Row upon row of municipal spearheads sat submerged in oil troughs, waiting for the final polish. The primary anvil sat empty. The iron tongs lay discarded on the dirt floor, tossed aside without care. The leather bellows hung motionless beside the brick hearth. The coals in the forge bed burned with a low, sullen orange glow, lacking the forced air required to maintain forging heat.
Torren Harrow was absent.
He left his tools scattered across the workspace. He left the fires untended. He treated the forge with the negligence of a man who assumed his wife would arrive to clean up his mess and fulfill his municipal quota. Yselle felt a cold satisfaction settle in her chest. His absence granted her the physical space she required to process the explicit freedom Callis had handed her in the street.
A shifting shadow near the ledger desk caught her eye. Yselle turned her head, resting her hand on her leather work belt.
A young woman sat on Torren’s wooden stool, hunched over a spread of vellum parchment. Yselle recognized the profile.
Mina. Torren’s niece from the provincial capital. She studied theoretical magic and runic application at the academy in the neighboring city. She visited the Lantern Ward twice a year to request copper stipends from her uncle to fund her tuition.
Mina possessed a striking, contradictory appearance. She wore round, wire-rimmed glasses that magnified her brown eyes. She tied her dark hair into twin ponytails that framed her face, giving her a bookish, sheltered demeanor. She wore a tailored wool bodice over a white linen blouse, paired with a dark pleated skirt to ward off the winter chill.
Her body defied the academic aesthetic. She possessed massive breasts that strained against the fabric of her clothing. The brass buttons holding the bodice together pulled tight, exposing the white linen stretched over the sheer bulk of her chest. The heavy flesh rested against the edge of the ledger desk, serving as a soft counterweight to the hard lines of the anvil and the iron tools.
Mina looked up, pushing her wire-rimmed glasses up the bridge of her nose.
"Aunt Yselle," Mina greeted. Her voice held a soft, breathless quality, lacking the harsh cadence of the working lanes.
"Torren is absent, niece," Yselle stated. She walked toward the desk. She kept her posture loose.
"He went to the municipal armory to argue about the silver tariffs," Mina explained. She shifted on the wooden stool. Her massive breasts swayed with the movement, the weight pulling the fabric of her blouse tight across her collarbones. "He told me to wait here. I was reading the runic schematics he copied from the Guildmaster's archive."
Yselle stopped beside the desk. She looked down at the parchment. Intricate, geometric lines covered the page, detailing the kinetic bindings used to strengthen municipal armor against canopy predators.
"Torren does not understand runes," Yselle noted. She picked up a piece of charcoal and tapped it against the vellum. "He hits iron with a hammer. He relies on municipal spell-weavers to bind the metal after it cools."
"I know, Aunt Yselle," Mina murmured. She looked up. Her brown eyes tracked the dark soot staining Yselle’s forearms and the defined muscles of her shoulders beneath the linen tunic. A flush crept up Mina’s neck. "He copies the shapes, but he lacks the intent. You forge the blades he takes credit for. Everyone at the academy knows the Ash Forge produces superior steel because of your hands, not his."
"This rune," Yselle said, keeping the piece of charcoal pressed against the parchment. "It binds the carbon to the iron. It prevents the blade from shattering under impact. But the magic requires a pure physical foundation. A grounding force."
Yselle dropped the charcoal. She studied the young woman. Callis had laid down the parameters of the alley. The women had to be adult, willing, and clear-eyed. No coercion. No secrets that brought danger to the hearth.
Mina sat on the stool, her chest heaving, staring at Yselle with unguarded hunger. The academic magic student spent her days reading theoretical intent in dusty libraries. She sat in a room filled with physical, manifested power, and she wanted a taste of the heat. But beneath the hunger, Yselle recognized the rigid, untouched posture of a girl who only knew the world through books.
"You smell like old parchment and unspent heat, Mina," Yselle observed. Her voice dropped into a low, rough register. "You sit in your academy, carrying all that heavy flesh on your chest, and no one has ever put a hand on you. You are a virgin studying kinetic bindings."
Mina’s breath hitched. She did not deny the accusation. She leaned forward, her wire-rimmed glasses fogging at the edges.
"Your uncle demands compliance from the women in his family," Yselle said. She reached out. She rested her soot-stained hand flat against the center of Mina’s chest. The heat of the forge paled in comparison to the frantic pulse Yselle felt beneath the wool bodice. The massive swell of Mina's left breast filled Yselle's palm, the soft flesh yielding to her calloused grip. "He expects nieces to sit quietly and read. But a dutiful niece should learn the practical application of her studies. Your aunt is going to teach you how to ground a physical anchor."
"Yes, Aunt Yselle," Mina whispered.
Yselle used her free hand to unfasten the top brass button of the bodice. It slipped free with a quiet snick. She unfastened the second. The third.
The fabric parted. The sheer volume of Mina’s breasts spilled outward, freed from the restrictive garment. The pale, dough-soft flesh swayed in the humid air of the forge. Large, dark areolas crowned the peaks, hard and tight with arousal.
Yselle stepped closer, trapping her niece between her body and the ledger desk. She lifted both hands. She weighed the massive breasts in her palms, kneading the thick flesh. Her calloused, soot-stained fingers left dark smudges across Mina’s pristine skin. The visual contrast marked the girl, branding the virgin student with the residue of the working lanes.
Mina let her head fall back. Her twin ponytails brushed against the parchment on the desk. "Aunt Yselle," she gasped, her academic composure fracturing.
"Good," Yselle murmured. She squeezed the heavy flesh, watching the pale skin bulge between her dark fingers. "Keep saying it. Let your aunt feel the weight of you."
Yselle gripped Mina by the waist. She pulled the young woman off the stool. Mina stumbled forward, her leather shoes catching on the dirt floor, but Yselle held her upright. The sheer bulk of Mina’s bare breasts pressed against Yselle’s canvas tunic, transferring the dark soot onto the white linen blouse beneath them.
Yselle guided her niece toward the primary workbench. Torren had left a pair of iron tongs, a ball-peen hammer, and a wooden measuring gauge scattered across the scarred oak planks.
Yselle did not bother organizing the tools. She swept her arm across the wood. The iron tongs and the hammer crashed onto the dirt floor with a loud, metallic clatter.
Yselle lifted Mina by the hips and set her down on the cleared workbench. Mina sat back on her hands, her spine bowing inward. Her massive breasts heaved with every ragged breath.
Yselle stepped between Mina’s legs. She caught the hem of the pleated skirt and pushed the fabric up, bunching it around Mina’s waist.
Mina wore thin cotton undergarments. A dark, wet stain had soaked through the center of the fabric. The scent of her arousal mixed with the smell of charcoal and flux, adding a sweet, musky note to the heavy air.
"You read runic schematics while you wait for a man who hates magic," Yselle noted. She hooked her thumbs into the waistband of the cotton fabric. She pulled the undergarments down Mina’s thighs, freeing her. "And you soak through your clothes the moment your aunt touches your chest. You are desperate to be broken open."
Mina nodded, her brown eyes wide behind her glasses. "Please, Aunt Yselle. Show me."
Yselle ran her palms up Mina’s bare thighs. The skin felt soft, lacking the callouses and muscle tone built by manual labor. Yselle reached the junction of her thighs. The swollen, pink flesh dripped with moisture. The untouched entrance held a rigid, nervous tension, but Mina’s natural lubrication coated her skin, gleaming in the dull orange light of the forge bed.
Yselle dragged her thumb through the wetness. She spread the moisture upward, coating the swollen clitoris. Mina arched her back, a sharp gasp tearing from her throat. Her twin ponytails bounced against her shoulders.
Yselle curled her ring and pinky fingers against her palm. She extended her index and middle fingers. She lined them up against the tight, virgin entrance and pushed forward.
The slick, yielding flesh parted, but the tight band of untouched muscle fought the intrusion. Yselle did not rush. She applied steady, relentless pressure, her calloused fingers stretching the virgin tissue. She breached the hymen in a single, measured push, sinking her fingers to the knuckles.
Mina threw her head back. A high, piercing wail ripped from her throat. She sounded nothing like an academy student. The raw stretch of her flesh stripped away her bookish dignity, leaving her squealing like a stuck pig on the slaughterhouse floor. The sharp, frantic noise echoed off the stone walls, cutting through the ambient hum of the forge.
"Take the stretch, niece," Yselle commanded, her voice cutting under the squeal. Her hands gripped the edges of Mina's thighs, forcing the young woman's knees wider.
Yselle pulled her hand back, letting her fingers slide out until only the tips remained inside. She drove her hand forward again.
The sound started.
Every upward thrust produced a loud, wet slapping noise. The sheer volume of Mina’s virgin lubrication mixed with the aggressive friction of Yselle’s calloused fingers. The action created a continuous squelching sound. It popped and slurped with every stroke, layering a filthy, wet rhythm beneath Mina's continuous, panicked squeals.
"Listen to it," Yselle instructed. She locked her gaze on Mina’s flushed face. She maintained a steady, mechanical rhythm, pumping her hand like the pistons on the Guildmaster's water wheel. "Your body talks to your aunt. It begs for the depth."
Mina whimpered, the squeal breaking into ragged, breathy sobs. "Aunt Yselle—it burns—it fills me—"
"It burns to forge the metal," Yselle corrected. She pulled her fingers back, breaking the suction seal with a sharp pop, and slammed them back into the wet heat. A sloppy, heavy slurp answered the motion. "You spent your life reading theory. This is the physical reality. Let your aunt ground you."
Mina lost all remaining composure. She let her head fall back, her glasses slipping down her nose. Her massive breasts slapped against her own ribs with every thrust, the dark areolas trembling under the force of the rhythm. She squealed again, a long, high-pitched barnyard sound that vibrated with raw, animal panic and overwhelming pleasure.
Yselle shifted her angle. She hooked her fingers upward, pressing into the deep, textured ridge on Mina’s upper wall.
The shift in leverage shattered Mina's academic mind. She clung to the edge of the workbench, her hips bucking upward to chase her aunt's hand. The virgin tissue stretched, yielding to the punishment.
"Aunt Yselle," Mina squealed, the words tumbling out between ragged, breathy sobs. "I will be your whore. Whenever I visit the ward, I will be your whore. Please. Break me."
"You belong to my forge now, niece," Yselle declared.
She used her thumb to rub a relentless circle over Mina’s clitoris, pairing the internal friction with direct stimulation.
Mina let out a final, shattered shriek. Her thighs trembled. The muscles locked tight. A cascade of violent spasms rippled through her core. Her internal walls seized around Yselle’s knuckles, crushing the calloused skin. The virgin muscles milked Yselle's hand, forcing the air and moisture out. The pressure produced a continuous popping noise that lasted as Mina shuddered through her first climax.
She sobbed, her body going limp against the workbench. Her twin ponytails hung in disarray. She squeaked weakly, the aftershocks of the release leaving her lungs empty.
Yselle kept her hand inside, riding out the contractions. She felt the tension bleed out of her own shoulders. The psychological rot Torren inflicted had been scoured away by the wet, slurping reality of his niece's ruined body.
Yselle pulled her hand back. Her fingers slipped free with a wet pop.
She picked up a linen rag from the tool rack and wiped the moisture from her skin.
Mina sat up. Her legs shook as she slipped off the workbench. Her leather shoes hit the dirt floor, but her knees refused to hold her weight. She dropped to the ground. The academic detachment had vanished, replaced by a raw, instinctual need to acknowledge the woman who had broken her open. Driven by a sudden, undeniable impulse, Mina crawled forward over the soot and ash. She lowered her head and pressed her lips to the scuffed leather of Yselle's heavy boots. She kissed her aunt's feet, leaving a wet mark of saliva against the soot, sealing her submission in the dust of the forge.
Yselle looked down at the kneeling girl. She reached out and gently pushed Mina's wire-rimmed glasses back up the bridge of her nose.
"Get up, niece," Yselle instructed, her voice calm and steady. "Fix your clothes. Your uncle will return soon to complain about his tariffs. He expects to find an obedient girl and a quiet forge."
Mina scrambled upright. Her hands trembled as she pulled her undergarments up, smoothing her pleated skirt. She pulled the wool bodice over her massive breasts, fastening the brass buttons to hide the soot stains her aunt had left on her skin. She tucked the secret away beneath the fabric, a private binding stronger than any rune she studied at the academy.
Yselle walked to the hearth. She picked up the heavy iron tongs from the dirt floor. She grabbed the handle of the leather bellows and pumped a steady stream of air into the forge bed. The coals flared, shifting from a sullen orange to a blinding, vibrant yellow.
