The sultry cowgirl leaned over the wooden milking station, her voluptuous body on full display in the dim, glowing light of the demon horse's stable. She was a vision of filthy temptation: long, flowing silver-white hair cascading down her back with purple tips that shimmered like forbidden candy, framing a gorgeous face with sharp purple eyes, full lips parted in a needy smile, and flushed cheeks. A wide-brimmed cowboy hat with a glowing purple gem sat atop her head. Her massive, heavy breasts strained against a skimpy cow-print bikini top, nipples visibly poking through the thin fabric, while the matching thong barely covered her plump, jiggling ass. Cow-print arm sleeves and thigh-high stockings hugged her thick, juicy thighs and arms, accentuating every curve of her naked, sweat-glistened skin. Two overflowing buckets of thick, creamy "milk" sat at her feet—harvested from previous sessions. She was here to milk the massive Demon Horse again, her pussy already wet at the thought.

"Aww, big boy... time to fill these buckets," she cooed, positioning the glowing cock-sucking pump over the enormous, veiny equine shaft that throbbed angrily in front of her. The Demon Horse snorted, its glowing turquoise eyes fixed on her barely-covered body, pre-cum already drooling from the flared tip.

But the beast was far too horny today. With a thunderous neigh, it reared up and mounted her instead, its powerful front hooves slamming down on either side of the milking bench. She gasped as the massive, glowing horsecock—thick as her thigh, ridged with demonic barbs and pulsing with unholy blue energy—slammed against her dripping pussy lips. "W-wait—AHN!" The flared head pushed inside her in one brutal thrust, stretching her tight human cunt wide open. Inch after inch of demonic horse meat invaded her, the glowing shaft pulling her body closer to its heavy, swinging balls with irresistible magical force.

Her legs trembled as the transformation began, slow and merciless. Starting from her toes, the skin of her feet softened and fused, layers of epidermis melting and reforming into smooth, dark equine cock-flesh. Muscles in her calves twitched and unraveled, fibers twisting and lengthening into thick urethral tubing and vascular tissue. Her thigh bones cracked and dissolved, marrow replaced by spongy corpora cavernosa that inflated with demonic blood, while her femur reshaped into rigid supportive cartilage. The cow-print stockings stretched and tore as her legs magically curled upward, merging seamlessly into the Demon Horse's massive testicle sac. Her soft, feminine thighs bloated outward, skin turning leathery and blue-veined, becoming part of the heavy, cum-churning orbs that now dangled between the horse's hind legs. Every nerve ending fired in ecstasy as her lower body was overwritten—skin, fat, muscle, bone, and organs all converting layer by layer into sensitive, vein-riddled ball meat.

"Oh fuck... what is happening—nnngh!" she moaned, her waist cinching tight as the change raced upward. Her hips widened then flattened, pelvic bones grinding down into the base of the growing shaft. Blue demonic energy spread across her belly, veins bulging thick and black under her skin as her intestines coiled and flattened into the central corpus spongiosum. Her waist turned a deep, throbbing blue, every human organ—liver, kidneys, stomach—dissolving into pure cock tissue, pumped full of the horse's corrupting essence.

She slapped a hand over her mouth as pressure built in her throat. Something thick and insistent was trying to push out—her own reforming urethra. Her massive breasts began to deflate slowly, saggy at first as the fatty tissue migrated downward, nipples hardening one last time before sinking into her chest. The soft mammary glands compressed, milk ducts rerouting into seminal vesicles. Her arms followed, elbows locking as muscles and bones retracted inward; skin stretched tight over expanding chest flesh. Layer by layer—dermis, subcutaneous fat, pectoral muscles—her upper torso ballooned outward into the thick, medial ring of the Demon Horse's shaft. Her ribcage cracked and fused, expanding into the powerful erectile chambers, veins wrapping around the new girth like ropes. What was once her chest was now a bulging, blue-veined horsecock midsection, pulsing with raw demonic power.

Her long silver hair fell out in clumps, strands dissolving into nothing as her skull reshaped. The bone structure softened from the inside—cranial plates shifting, jaw elongating into the flared head of a massive horsecock. Her pretty face swelled grotesquely, cheeks bloating as cartilage and flesh molded into the blunt, medial ridge. Her purple eyes squeezed shut in overwhelming pleasure, eyelids fusing over as optic nerves repurposed into sensory endings for the cockhead. Her full lips stretched vertically, parting into a long, drooling vertical slit—the new pisshole and cum-slit—while her tongue flattened and merged into the sensitive inner walls. Teeth dissolved, nose flattened, every layer of her facial anatomy—epidermis, muscle, cartilage, and skull—completely overwritten into throbbing, flared horsecock glans. The last of her human thoughts melted away in a haze of pure equine lust.

The fully transformed Demon Horse now sported an enormous, glowing blue-veined horsecock where the cowgirl once knelt—her entire body reduced to its throbbing, cum-bloated length. With a triumphant roar, the beast slammed its new cock into the waiting pump. Massive ropes of thick, demonic horse cum erupted through the vertical slit, flooding the machine in powerful jets that overflowed the buckets. Gallons upon gallons of hot, sticky seed pumped out in endless spurts, the remnants of her old form fueling the orgasm.

The Demon Horse stood victorious, its new cock still twitching and dripping, ready for the next milking.
