Nature Calls "Caption"

Hello!  I wrote the "caption" for the recent Nature Calls illustration.  I hope y'all like it! :)

Vivian stumbled behind Lucas.  She leaned against the tree next to her, swaying as a sudden wave of heat left dizziness in its wake.  Tendons stood out on the back of her left hand where it gripped the trunk, twitching until her nails bit deep to score the bark.

A single bead of sweat formed on her brow before sliding down the tip of her pert nose, rounding the curve and further to her lips where she licked it by reflex.

More sweat formed, soaking into her loose shirt and trousers.  She grunted, grinding her teeth.  Sawing them back and forth.  Her jaw muscles flared, pushing against her cheeks as she tried to massage the soreness spreading throughout her gums.  Finally, with an unnaturally deep groan, she rested her forehead against the tree.

Invisible fingers scored her flesh.  She snarled, snapping her head around but there was nobody behind her.  The tendrils burrowed deep, tearing through her muscles with a sharp ache that bordered on pain.

She tried to call out to Lucas, but her voice wouldn't come.  Her throat felt impossibly dry and her tongue clicked against the roof of her mouth.  He stood away from her, frowning at the landscape beyond with a map in his hand, engrossed in his observations.

Muscles shifted, pulling tendons and the bones themselves.  Vivian groaned and leaned forward while flexing her shoulder blades as they bulged against her skin.

Pain flared in her hand. Vivian snarled, snapping her teeth as she turned to stare.  Beads of bright blood slid down the tips of her fingers. She could smell the sharp, tangy scent of her own blood. The young woman snorted and huffed with her eyes narrowed.  It was impossible, of course, but she swore the coppery scent filled her nose.  A delirious swirling haze infiltrating her mind.  Drool welled at the corners of her mouth.

Hot slicing pain shot through her fingertips.  The girl hissed and pulled her hand away, only to be shocked at the weight of it.  Veins stood out on her smooth forearm beneath her rolled-back sleeves.  Her normally soft skin had tightened to show the muscle definition beneath and she watched in horror as her skin moved to adjust to the tissue multiplying beneath the surface.  Before she could investigate further, she watched a single black hair push through the skin.  A second emerged closer to her elbow while a third grew alongside the first one with a fourth following almost immediately in the same spot.  She reached for them, only to see blood dripping from the tips of her fingertips.

Skin stretched over the hand, hardening as muscles grew within, widening her hand millimeters at a time.

"Wha- what-" she sputtered before growling and gnashing her teeth.

Vivian slowly fell to her knees.  Her ass touched her heels and a tear formed in the seat of her pants, ripping to show her panties.  Drops of sweat glistened on her ass cheeks in the sunlight showing through the trees.

The ghostly sensations returned to burrow into her fingers.  Keratin multiplied from the root of her fingernails, diving through the flesh to attach to the tips of her bones.  Anchoring them in place before spreading outward.  She stared, in horror, as the ivory growths cleaved her fingertips in half in order to attach to her nails with a curving, deadly arc.

Her short proto-claws shuddered before stretching away from her fingers.

"Nuh-no," she groaned, scratching at her hands as if she could halt the changes.

Swollen flesh from her palms rubbed thick black hairs growing over the backs of her hands.  Vivian turned her trembling hands to see a thick callus forming on the top of her palm along the entire width of her still widening hands.  Smaller bean-like calluses grew from each segment on the bottom of her fingers.

The faint itching sensation in her gums worsened into a throbbing pain around the roots of her teeth.  Vivian panicked, pulling at her backpack.  Her paw tore through the straps as if they were tissue.  When she grabbed at the elastic cord holding the flap over the top, hardened muscles showed in her bare forearms and her bicep bulged, pulling her shirt sleeve taut until the seams strained.  The backpack's cord tore and the flap was ripped away, scattering the contents.

Vivian's ears twitched as Lucas muttered about finding a lake. In her panic, she'd forgotten about him.  Now she vaguely heard him ask her to stay in the clearing while he ranged ahead a bit, but she was distracted by her search for a mirror. The woman's lips bulged over the base of her cuspids when they split the gums to lengthen in her jaw.  She roared as she pawed through her gear until she found the mirror, shattering it when her paw closed around it with too much strength, despite trying to restrain herself.

"Nooooo," she moaned with a grumbling, deep voice.

The young woman picked a large shard from the bulging padding on her broad paw.  She angled it and stared at her face.

At her curved fangs jutting from the top and bottom of her jaws.

At the trace of black fur growing down the back of her jaw.

At her ears when her earlobes vanished due to the skin stretching outward into a broad, rounded shape covered by fuzzy little black hairs.

The shard slipped through her thick fingers. She slumped forward on her hands and knees, growling quietly with her eyes closed as a billion ants crawled beneath her skin.

The stretchable fabric of her sports bra tightened on her chest.  She inhaled a ragged, deep breath and fine tears formed in the back of the bra.  Her expanded chest continued to widen and the sound of her cracking, creaking, groaning bones filled the small clearing.

A seam popped on her sleeve.  Even with her arm straight, her biceps were defined - pure power barely restrained.  More stitches popped, ripping the sleeves in half to show corded, veiny muscular arms covered by scattered black fur.  As huge as she was already, she stared in shock as the lightly furred skin moved when they stretched over new muscles forming below the surface.

Her entire body felt simultaneously heavy and light at the same time.  Gravity pulled at her bulk but the coiled strength continuing to develop allowed her to move effortlessly.  She could feel it winding within her.  Tightening endlessly with the itching, creeping sensation growing worse.

Vivian roared.  Spittle flew from her fanged maw.  Her cheekbones broke, flexible for a brief moment before healing, wider than before, tugging at her nose while thrusting it forward into the start of her snout.  She leaned back and then stumbled up with a snapping huff.

The tree behind her cracked like a bolt of lightning when she slammed her body into it.  Leaves fell around her as she began to scratch her back and ass against the rough texture of the bark.  She reached up and the front of her shirt exploded to reveal her bare breasts and hardened stomach, abdominal muscles outlined by glistening, sweat-soaked skin with droplets clinging to the tips of black fur creeping up from the waistband of her pants.

Vivian grunted while gripping the tree above her head.  Her breasts lifted before swinging from the motion.

Fatty tissue grew over the muscles forming in her ass.  The tear in her pants widened while her panties tightened into a narrow strip that slipped between her swollen, reddened outer labia.

Curly tufts of black fur hid her sex from view.  Her meticulously clean shaven mound, pussy lips and crotch were covered by bushy, wild hairs now.  Strings of clear cum dangled between the strands of hairs until her violent scratching caused them to collapse.

The flat laces criss-crossing her shoes pulled into narrow strings over her expanding feet.  Vivian snarled and kicked, shoving the tips of her shoes into the dirt.  She could feel her toes popping within, the pain mixing with the slicing sensation of her toenails connecting to the bones just as her fingernails had earlier.  When they lengthened, forcing her toes to scrunch backwards, they grew to sharp tips that tore through the faux leather of her left shoe before plunging into the dirt beneath.  Her right shoe burst from the rapid expansion of her foot.

Vivian was distracted, ignoring the pain in her legs and feet as her panties sawed back and forth between her pussy lips.  And her engorged clit.  She moaned, tearing chunks from the tree as she clawed her massive paws down the trunk.

The emptiness between her thighs - within her guts - left her snarling.  The skin over the bridge of her broad nose wrinkled and she flashed her fangs.  Her panties snapped, stretched beyond their limit by the expansion of her ass.  The delicate restraint holding the beast in check broke and she roared when the pleasure vanished to leave only the dull ache behind.

She raised her chin, huffing as she scented the air and her fleshy, thick tongue rolled out to lick at the blackened tip of her nose. Her thighs brushed together when she followed the scent of her boyfriend.  She kicked her feet as she walked, flinging her shoes from the three inch long black claws tipping her toes.

A broad line of thin fur rocked on her muscular back.  The hairs crept down, over her spine and to her sides.  The gaps of bare skin began to vanish when more hairs emerged and the existing ones lengthened.  A bony mound pushed the skin above the split in her round ass cheeks.  The stump of her new tail wiggled as she walked.

Lucas turned just as she approached.  He screamed when she grabbed him and fell with one paw cradling the back of his head.  Pinned down, she licked his face with long strokes of her tongue while grinding down against him.

Blue veins stood out on her breasts.  Hairs grew between them, slowly covering her sternum while the skin stretched over her tits.  Milk welled from the holes in her dark, erect nipples.  They dribbled down to soak into Lucas' shirt - a slow, irregular flow at first, but soon a steady stream as new lobules formed over the muscles expanding within her chest.  More fatty tissue grew and her modest breasts swelled to dangle beneath her.  They bulged out to the side when she flattened them against Lucas' chest.  Her wetness drenched him down to his cock.

He grew hard against her despite his struggles and when she sat back with a growling, happy groan, he gasped as he recognized her features in her expanding muzzle.

"Vi- Vivian?!  Is that- fuck!" he yelled when she raised her hips to slip her claws into his pants.  A simple tug ripped them away with his underwear.

"Yesssss," Vivian said as she lowered herself once more.  Her fur swayed over her torso, almost hiding the outline of her colossal body as she dwarfed her boyfriend.  The woman's new pelt was thick but flashes of her muscles showed beneath.

She grinded against him, grunting while her jaw cracked.  At the apex of her motion, she felt the head of his cock press between her dripping, burning pussy and she froze while hunching her body.  Her enormous breasts pressed into Lucas' face with her nipple flexed and resting against his nose.  She moved, dragging her tit down, over his chin until her nipple touched his open lips.

When she tried to tell him to suck on her, she found she could no longer make words.  His hesitant hands reached for her, touching her sides and back and hips... and up to her breasts.  She moaned and the air vibrated from the deep sound when she felt teeth scraping her nipple and a dextrous tongue working against it.  The hardened nipple stretched, growing to fit her larger form and lightning arched down her belly.

Vivian pushed, taking her boyfriend's cock easily inside.  He grunted when she clenched powerful, slick muscles around his dick and then threw his head back when she began to move.  Her wet nipple popped free, but she ignored it as the head of his cock rubbed the clusters of sensitive nerve ending within her pussy.

She pawed at the earth with her enormous breasts quaking and slapping together while her ass thumped against Lucas' thighs.

"C- c- careful," he hissed and she snarled but slowed and then moaned when he grabbed her breast to take the nipple back into his mouth.  He kneaded the soft skin and milk flowed once more, surprising him into swallowing.  The man suckled her while she rode his cock, grunting faster and faster and-

Vivian bellowed with her head back and her snout pointed skyward. She was already close, having pushed herself to the edge when grinding against the tree.  But, it wasn't just that. Something wild woke within her - wild and hungry and free of her subconsciously held self-control.  The animal wound its way through her psyche, overwriting various pieces until it felt natural and good to fuck her mate in the wild where anyone could see.

What was once reserved for a bedtime ritual now became something she would lust for at any time, bending over and spreading her massive, furred ass cheeks with a hungry look when she felt the urge rise within.  Multiple times a day as the flame of her libido grew to a roaring bonfire.

Close.  Close close close so close close oh god oh god oh god so close! she yammered in her head, slamming down on her boyfriend while tearing chunks of dirt from the ground.  Her cum splattered over her fur and Lucas' crotch and legs.  The woman's lips flexed over rows of fangs while her eyes widened to stare far into the distance.

She bellowed again when the building orgasm broke within.

Vivian stretched out, leaning forward with her muzzle snapping at the air above her boyfriend.  Drool flung from her lips while her body trembled.  Hidden beneath the fur, veins stood out on her reddened neck.

It seemed endless and her pulsing, clenching pussy milked her boyfriend's cock the entire time, robbing him of his own self-control.  He hissed as he came deep within her and Vivian moaned and bent to lick her boyfriend's face while his cock swelled inside of her.

Finally, she rolled to her side and his cock slipped free.  Vivian wrapped her massive arm around her boyfriend to pull him against her chest, pressing her enormous breasts against his nape while licking his hair and gently stroking his body with the tips of her claws.

The intense arousal had abated somewhat.  It still lurked - an alien sensation that begged for attention but allowed itself to be ignored.  For now.

Food would be needed soon.  And a healthy amount of panic.

Her paw slid over Lucas' chest until she felt his heart beating against her paw pad.  It anchored her, allowing her to calm herself and she breathed deeply of his scent.

I love you, she thought.

"I- I know," he told her, not even realizing that she hadn't spoken out loud.  "We- we should talk.  About what happened. And- we're not, we're not in the same- the map is all wrong and- wait. Wait.  Did you- did I hear you in my-"

Food first and then talk, she told him, rolling away on all fours to shake herself before slowly standing on two stump-like legs.

"Y- yeah," he said, rubbing his ears and looking up at Vivian with wonder as he stood beside her.  "Food first."

"And then we talk."
