Part of the plant garden

Maria sprinted toward the first green pipe, her boots pounding against the dirt as she calculated the jump. The damn thing was taller than usual, but she'd cleared worse—until the moment her fingers grazed the rim, something snaked around her ankle. A gasp tore from her throat as she was yanked backward, the world flipping upside down. The Piranha Plant's vine-like grip hauled her into the pipe's dank interior, its petals parting in a lurid grin. "Well, well," it purred, voice thick with syrup-slow menace, "look who fell into my garden."

The stench of damp earth and something cloyingly sweet filled Maria's nostrils as the plant's bulbous body pressed against her. Its "hands"—broad, veined leaves—pinned her wrists to the slick pipe walls while its mouth, glistening with sap, descended. The kiss was less a kiss and more a violation, its tongue pushing past her lips, filling her throat with a viscous, honeyed liquid. Maria gagged, thrashing, but the plant only laughed, its hips grinding against hers. "Shhh," it cooed, "you'll love this part." Then—wet pressure, darkness—as it shoved her head between its jaws.

Maria's vision swam as the Piranha Plant's thick, nectar-slick tongue **** itself deeper into her mouth. The liquid it pumped down her throat burned—not painfully, but with a strange, creeping heat that spread through her limbs like syrup. Her fingers twitched, then stiffened, the skin darkening to a vibrant green as her nails elongated into veined, leafy tendrils. A whimper escaped her throat—or tried to—but the plant swallowed it greedily, its bulbous head bobbing as it worked her jaw wider, wider, until her lips stretched beyond human limits, puffing into plush white petals.

Her cap tumbled away as her hair dissolved, scalp smoothing into the same waxy red as the plant's own. The spots bloomed across her skin like mold on fruit, white and perfectly circular. Maria's hips jerked involuntarily as her thighs fused, flesh knitting together into a single, root-like appendage. The Piranha Plant finally released her mouth with a wet pop, only to seize her wrists—now fully leaf-shaped—and pin them above her head. "Look at you," it crooned, tracing a leaf-hand down her newly rounded belly, "so much prettier when you're not fighting." Maria tried to protest, but her tongue was different now—thicker, sharper—and all that came out was a hungry hiss.

The transformation reached its climax when her feet merged, toes splitting into fibrous tendrils that coiled around the plant's own. It shuddered, pressing its full weight against her, and Maria felt something inside her click, like a key turning in a lock. Resistance melted. The last dregs of her humanity evaporated as her thoughts simplified—no more Peach, no more Bowser, just the sweet, suffocating press of the Piranha Plant's body and the ache between her thighs. When it finally pulled back to admire its work, Maria lunged forward, sealing their mouths together in a kiss that was all teeth and sap.

They tumbled from the pipe in a tangle of limbs and roots, Maria's new body moving with instinctive grace as she straddled the Piranha Plant in the grass. Its laughter vibrated against her lips as she ground against it, the friction sending jolts of pleasure through her altered nerves. Somewhere distant, Peach's voice still echoed—Maria, please!—but the sound meant nothing now. The transformed heroine arched her back, leaves rustling, as the plant's hands gripped her waist, their bodies moving in perfect, wordless sync.

The Piranha Plant's grip on Maria's leafy wrist loosened as its body shimmered, vines retracting into sinewy flesh. With a wet, organic pop, its roots reshaped themselves—elongating, thickening—until two muscular, humanoid legs stood where tangled tendrils had been. Maria blinked, her new floral eyes wide as the creature offered a hand, its once-carnivorous mouth now curved into something resembling a smile. "Come," it purred, voice dripping with nectar-thick warmth. "You belong with us now."

Maria hesitated, but her body moved before she could think, roots slithering obediently across the damp earth as she let herself be led. The world smelled different—rich, pungent—every breath filling her with the heady musk of fertile soil and something sharper, like overripe fruit. They passed clusters of her kin, their bulbous bellies swaying as they tended to groaning, vine-wrapped egg sacs. Some had arms now, slender and green, fingers brushing each other's petals in slow, intimate circles. Others had sprouted thick, pulsating stems between their thighs, their tips glistening with sticky dew.

A low hum vibrated through the clearing as they approached the center, where Piranha Petey lounged on a throne of intertwined roots. His body was massive, each corded muscle flexing beneath emerald skin as he stroked the trembling stem of a kneeling female. His cock—thick as Maria's forearm, veined and rigid—stood at attention, its tip weeping translucent sap. The transformed Piranha Plant nudged Maria forward, its leaves pressing insistently between her shoulder blades. "Kneel," it whispered, breath hot against her petals. "Let him taste your bloom."

Maria's knees hit the soft earth without protest. Her body knew this dance, even if her mind still flickered with fading resistance. Petey's nostrils flared as she approached, his clawed hand seizing her chin to tilt her face upward. "Fresh pollen," he rumbled, thumb brushing her lower lip until it parted. "Good." Behind her, the crowd of Piranha Plants pressed closer, their murmurs rising to a hungry chorus as Petey's free hand gripped his shaft, pumping lazily.

The first thick droplet of his nectar splashed across Maria's tongue, and her back arched violently, roots writhing. It was electric—better than any power-up, any star—flooding her veins with liquid heat. Petey groaned as her mouth closed around him, her new instincts guiding her lips and tongue in practiced motions. The clearing erupted in wet, rhythmic sounds as the other plants paired off, vines entwining, stems plunging into willing blooms. Maria gagged as Petey's girth stretched her throat, but her body welcomed it, petals fluttering around his base as her own hidden slit pulsed with need.

Petey's tongue plunged into Maria's mouth with the same brutal rhythm as his hips, his thick, sap-coated muscle forcing her jaws wider as something small and firm pressed between their lips. The mushroom hit her tongue with a burst of earthy sweetness before dissolving, its effects immediate—her breasts swelled against his chest, heavy and round as ripened melons, while her ass inflated with obscene plumpness, the cheeks quivering with each thrust. She moaned around his tongue, her nipples budding into delicate white flowers that dripped nectar down her curves. Petey growled approval as thorns erupted along her shoulders and thighs, glistening like dew-tipped daggers in the dappled light.

His climax hit with a guttural roar, his cock pulsing inside her as seeds—not semen—flooded her depths. They took root instantly, her belly distending as tendrils of green spread beneath her skin, weaving her flesh into something new. Maria arched, her back bending impossibly as her spine elongated, segments forming like a stem. Her fingers melted into broad, veined leaves, her toes twisting into anchoring roots. Petey withdrew with a wet slurp, his seed still dribbling from her swollen slit as he adorned himself—spiked metal collars clamping around his throat, wrists, and ankles, the glinting points a cruel contrast to his verdant flesh.

The last flicker of Maria's humanity faded as her thoughts dissolved into primal urges. Capture. Consume. Reproduce. Her once-bright eyes dulled to glassy black orbs, her mouth now a gaping maw of razor-sharp petals. She tested her new body, flexing thorn-lined limbs, a purr rattling in her throat when Petey stroked the vines now coiled around her waist. "Beautiful," he murmured, nipping at her floral nipples. "The garden welcomes you."
