"Ah, dammit!" A loud rustling and cracking echoed through the forest, followed by a heavy groan as Tara crashed into the bushes at the bottom of a small ditch. Even though thorns scraped across her hazelnut brown fur, the young mare didn't mind that she had tumbled into the thicket. She could handle a few scratches, but not broken bones from smashing into a rock or the bare ground.

After dragging herself out of the brambles, the equine briefly made sure that the satchel around her neck was still there. "Gotta be more careful next time." Then she looked up. The light that filtered through the canopy had adopted a warm orange hue as the day was drawing to a close. "Dang, how's it so late already? I should be in Clover's Brook by now," she snorted, gnashing her teeth as she put her left hoof forward. Instantly, a sharp pain shot up her leg and through her whole body, almost making her fall back into the thorny thicket. "Fucking Fay and your fucking shortcut. I don't care how much you're paying me for this shit. This is the absolutely last time I'm fetching any ingredients for your dumb potions, you stupid nibbler."

Tara took a deep breath to calm her frazzled nerves. Then she inspected her surroundings a little closer. Unfortunately, no matter where she looked, it was all brambles. Left, right, ahead, and behind, it was bushes upon bushes between the trees, not even a hint of a trail to be found anywhere. The only somewhat clear stretch was the slope she had stumbled down, and she grimaced only from thinking of scaling the incline with her crippled leg. For better or worse, she had to call it a day and settle down for the night.

Somewhere in the middle of nowhere, between dirt and the dense, thorny thicket.

It didn't help that there was no decent food nearby, and no water either. But while Tara wasn't desperate enough to choke down dried-out brambles yet, a day of walking across uneven terrain and beneath the hot late summer sun had left her fur soaked with sweat and her muzzle dry as dust. Too thirsty to lie down, she perked her ears and listened to the voice of the woods. It was uncomfortably unfamiliar. An muffled, eerie buzzing resounded from the rustling leaves and branches instead of the melodic warbling of birds. At least, her swiveling ears finally picked up the quiet babbling of flowing water. There was a creek somewhere behind the bushes!

Behind the bushes.

The mare wrinkled her snout as she stared at the dry brambles in front of her. Thousands of little spiky thorns glittered at her menacingly, but it was no use. This was the way to water, so she gritted her teeth and stepped forward, pushing her way through the undergrowth no matter how much more it scratched her up. Her reward would be more than worth it, she tried to convince herself as every fourth step added another pinch of pain to her slog.

She really hoped that she could carry on tomorrow.

And all that for a few bushels of weird, overpriced herbs…

Fortunately, Tara would finally find some respite from her ordeal when she reached her destination. As she stepped out of the awful thicket, she found herself at the edge of a small clearing with lush green grass, colorful wild flowers, and the babbling creek she had heard earlier winding across it. "Thank the Gods," she whinnied and stumbled toward the rivulet, dropping down on her forelegs to take her first sip after hours of toil. She sighed with bliss as the cool water washed down her throat and she pushed her entire muzzle into the stream, guzzling down three entire gallons of the refreshing wet.

After the mare had quenched her dire thirst, she stepped across the narrow creek and rewarded herself with a big bushel of grass and flowers, savoring the moist, slightly honeyed aroma like it was the plumpest, sweetest apple. Better yet, the lush little clearing would make for a terrific bed because there was no way she could sleep standing with her aching ankle. Her battered, sore muscles and body required proper rest, and so she lay down on her side, her damaged foreleg draped over the other. She looked up with a tired sigh, her thoughts drifting aimlessly for a little longer as she watched the night embrace the woods. But once the darkness snuffed out the last traces of the fading sun, a veil of twinkling stars and the soft shine of the waning moon, she finally closed her eyes and dropped off to sleep.

Tara's slumber ended far too early in the morning when a low, droning buzz yanked her out of her dreams. She woke up with a heavy gasp, her entire body burning as if it was on fire, and when she sluggishly opened her eyes, she spotted a strange, glossy dark green blur above her. Blinking a few times in groggy confusion, the uneven shape turned out to be the biggest, fattest fly she had ever seen. The hovering insect was almost as big as her head. Its translucent wings visibly bent as it struggled to keep its bloated body in the air before it landed on her with a heavy thud, its six spindly, hairy black legs sinking deep into her fur.

Muzzle open in breathless shock, the mare stared at the creature's vast, expressionless faceted red eyes before her attention shifted toward its abdomen. Its glossy, dark green chitin was grossly distended, bulging out between the seams of its exoskeleton with something big and squirming inside it. However, instead of gagging at the revolting sight, she burst into a deep, involuntary moan when a sudden flash of blinding pleasure ripped through her body. Not only had her loins turned into a glowing furnace overnight, signaling the premature arrival of her estrus, but her insides had become distractingly sensitive as well, responding to stimulation that shouldn't be there. Or so she thought at first….

Tara quaked, a perplexed whine erupting from her lips when another, even stronger surge of pleasure surged through her. This time, she clearly felt that there was something inside her channel as she clenched up, squeezing that foreign object with a wet squelch. Whatever it was, it was surprisingly soft and squishy. Then, it suddenly moved. It wasn't the kind of back and forth movement she knew from a stallion's swollen shaft, but a sluggish squirming as if someone was licking her with a very thick, lazy tongue. However, when she anxiously peered at her butt, it looked perfectly normal, all while that fat, pulsating something continued to writhe inside her, stirring a disorienting storm of tingles inside her loins.

"Oh fuck! What's going on? What's h-happening to me?"

The mare's vision blurred as she was struck by a fresh surge of her heat, and she instinctively lifted her tail to present herself to a male, even though there was none around. However, she wasn't actually alone. The fly on her side had taken advantage of her distraction to move to her rear, tickling her fat, dark folds and puffy asshole with its chitinous, cloven legs as it crawled all over her butt.

"H-huh? What's that weird feeling?" Tara tried to shoo the giant insect with her tail, but it was completely unimpressed by her attempts. Barely even flinching from her tail strikes, it clutched her plump, puffy pucker with its hind legs and lazily raised its pulsating abdomen, flexing it with a slimy squelch. Immediately, the squirming inside the fly grew more vigorous, its entire shining abdomen shaking and trembling. Then its rear end split open with a wet smack, the dark green chitin parting to reveal pale wrinkly tissue and a twitching hole inside. "Ick, what is it doing? S-stop it!"

At first, only a few drops of clear, viscous bug juices drooled from the dilating orifice, but after a few more rhythmic convulsions, a shiny dark dome with strange nubs and protrusions emerged from the fly's depths. Was it an egg? The mare's uneasy assumption proved completely wrong when another inch of the plump mass squeezed out of the green fly's abdomen. It wasn't its unborn offspring. No, it was its larva, a bloated sack of ribbed, squirming white flesh, and the strange dark protrusions it was now waving at her were its mandibles. It was also more agile than its chubby frame suggested, as it bent down toward her plump equine pussy and pressed against her sensitive folds with surprising dexterity.

Tara jerked up with a panicked squeak, reflexively clenching up as hard as she could to keep that writhing, dirty larva outside of her precious tunnel, but her resistance lasted only until the next surge of stimulation hit her like a falling rock. From one moment to the next, all the tension dissipated from her pussy, and her clit pushed free with a lewd smack, winking at the turgid maggot as if to invite it inside. 

The maggot eagerly embraced the invitation, squeezing its head past her pussy lips before she could clench them shut.

"N-no! No, no, NO! This is not happening! This can't be happening!" the mare whined, gathering all her strength to push back and expel the intruder. But no matter how much she strained and pressed, her cunt's contractions only managed to suck the fat larva even deeper. All the while, the fly perched atop her butt pushed its abdomen down with buzzing wings, shoving its offspring even deeper into her hot, moist depths.

The worst part of her ordeal? The maggot's vigorous wriggling flooded her with fresh stimulation as it wormed inside her pussy. A strangely familiar stimulation…

Tara's thumping heart skipped a beat when she realized what that unfamiliar object inside her was. Apparently, the larva that currently squeezed into her love tunnel wasn't the first one! While that horrifying realization sank its fangs into her poor, rattled mind, the fat maggot slipped fully out of its mother's abdomen, disappearing inside the mare's channel with an obscene shlorp. Another mind-breaking surge of pleasure shot through her as it joined its companion wiggling inside her, fueling her blazing heat and drowning out her terror until she saw stars flashing before her eyes.

The mare didn't understand how she could be so receptive to a pair of disgusting, slimy worms writhing inside her, snorting and huffing defiantly as their incessant shifting and squirming carried her ever closer to an involuntary orgasm. It wasn't fair. Half the time she had mated with real stallions, she hadn't even gotten close to a climax, but now that she was infested with dirty, bloated grubs, not even her stomach-churning disgust could contain her growing arousal.

Not that Tara would give in so easily. With gritted teeth, she tore her eyes away from her violated, winking pussy, and stared at the red skies above, lit by the early morning sun. Slowly, shakily, she dragged herself up onto her hooves, and it took all of her willpower not to collapse again as surge after surge of stimulation smashed against her battered spirit like raging waves against the shore.

"Fuck, get out," she growled, her eyes rolling back as she pushed with all her might. Again and again. Straining, groaning, whining, and sweating as she attempted to expel the two maggots inside her, but her desperate efforts were fruitless. She didn't even manage to get rid of a single one. Instead, they used her channel's forceful contractions to burrow even deeper inside her. At least that moved them further away from her sensitive entrance, so they no longer rubbed the most sensitive spots inside her. The pause in stimulation gave her just enough time to steady herself and watch as the giant fly took off and whizzed past her with droning wings. 

No longer burdened by its plump offspring, the fly looked like a completely different creature, its abdomen so sleek and slender. Only the gaping orifice at its rear and the distended, semi-translucent white tissue hanging out of it revealed what abomination had emerged from it, but Tara caught only a glimpse of it as the insect disappeared into the woods, leaving her to her fate.

Unfortunately, the calm wasn't meant to last. Once the deepest of the eager larvae reached the entrance to the mare's womb, it didn't just settle against it. No, it forced itself against the narrow, incredibly sensitive opening with unyielding force, and any composure that Tara had scraped together shattered in a firework of pleasure. The climax that had been brewing inside her broke loose, sweeping away her struggling mind and body, and she crashed back into the grass with a resounding neigh.

The mare's voice shook with abject helplessness and involuntary bliss as the maggot attempted to invade a space that no life had blessed so far. The woods blurred before her eyes as big, salty tears washed down her cheeks, and she almost choked on her spit as she caught a hasty breath before howling even harder as the stimulation ripping through her body refused to cease. Instead, it grew even more intense as the larva squirmed, thrust, and thrashed against her cervix without rest.

Tara's plump pussy clenched and convulsed so hard it hurt as she succumbed to the most intense climax of her life. Nothing compared to this moment as she lay there in the clearing, shaking and squirming on the wet grass like the dirty grubs deep inside her as disgust, terror, and otherworldly ecstasy drew closer together than ever before. Part of her hoped that her violent contractions would crush her unwanted intruders and put an end to this lewd nightmare, but it only riled them up further until the first maggot breached her cervix, squeezing through the tight opening one segment at a time.

The sensation of the fat, writhing larva invading her womb was so intense that the mare almost blacked out, foaming at the mouth as her pussy winked and clenched in an uncontrollable frenzy. Every time her clit flicked out of her roiling depths, she squirted her juices almost three feet across the clearing, soaking the flowers and sullying the creek with her lewd scent, and that was only the first of the two maggots. Before long, the second larva pushed against her dilated cervix as well, and it didn't bother to wait for the other grub to finish its passage, pressing against her already distended opening with all its strength.

Tara howled. She howled at the top of her lungs. She howled until her voice cracked and gave out. If there was anyone else in these woods, they would hear her, she comforted herself between quickening blasts of blinding stimulation. She didn't care whose attention she attracted. Anything would be better than this, and for what it was worth, she didn't actually have to endure the most intense, yet most regrettable, orgasm of her life until its shameful end. One fly larva squeezing through her cervix hadn't been enough to knock her out, but two finally overloaded her brain so much that everything finally went dark.
