Tara wasn't sure how long she had been out cold when she regained consciousness, but the sun stood still high in the sky, so that she should have enough time to escape from these forsaken woods before nightfall. Her sprained ankle still hurt, but at least there was nothing moving inside her. While the horrors she had experienced this morning were still fresh in her mind, making her shudder at the mere recollection, she wasn't even sure if that had actually happened, or if it was all just a feverish nightmare. Maybe she had eaten something bad?

Either way, the mare had had enough of this forest and wanted nothing more than to get out of it as quickly as possible. So with a heavy snort, she scrambled onto her hooves, shaking like a newborn filly taking its first steps. Unfortunately, her injured foot still made it impossible for her to climb the slope back where she had fallen yesterday, so she had to find a new way forward, but she didn't have to look long for an alternative route. She simply had to follow the babbling creek beside her, as it would inevitably merge into a bigger creek, then into a river, and where there was a river, the next village wouldn't be far.

Perhaps it even led her straight to Clover's Brook?

Filled with new confidence, the mare quenched her thirst at the rivulet. Then she started to pursue its winding bends deeper into the forest. The horrid memories of her morning soon faded into the back of her head. She didn't even have to crawl through any more brambles on her way, but after about an hour of walking, her estrus suddenly flared up with a vengeance.

Tara had been in deep heat before, but it had never been as excruciating as today. Normally, her heat came and went in waves, leaving her on the edge of sanity for half an hour before calming down for another hour, but right now, she was always hot, always horny, shivering and sweating as if she had a terrible fever. Her puffy pussy drooled and winked with almost painful cramps while her mind drifted off into lewd fantasies, distracting her from the root-riddled path ahead that she tripped at least once every minute.

Initially, the mare fantasized about the same things as during every other estrus. She imagined big, handsome studs, sleek Arabian stallions with shining black fur and fat cocks, and huge, bulky draft horses with giant rods mounting her, impregnating her one by one, blessing her with the first foals of her own. However, as her heat persisted and her arousal grew into desperate desire, she started drooling about increasingly… deprived things like becoming a donkey camp's brood mare, or allowing lowly kobolds and ratfolk to assist her with her predicament. Looking around, the rocks and branches scattered about the ground also looked more appealing than ever, and before long, she caught herself drifting back to those fat, wriggly grubs from her early morning nightmare.

"Fuck, what's wrong with me?" Tara groaned under her breath, stopping for the fifth time this hour to catch her breath and take another big sip from the creek. "I can't wait to get back to civilization. I really hope that Fay's stupid alchemist friend has something for this fucking estrus." She closed her eyes and gnashed her teeth, unsure how much longer she could endure this heat. Part of her was already desperate enough to allow any stray stallion to mount her and knock her up, but it was probably better to find herself a few incompatible locals to tend to her needs.

It regrettably wouldn't be the first time she'd resort to such humiliating measures…

The horny mare was still lost in her thoughts when a strange vibration reached her ears. It sounded like growling thunder, even though the specks of sky peeking through the canopy above her were bright blue and cloudless. With a furrowed brow, she perked her ears and listened more closely. 

An ice-cold shiver raced down her spine as she recognized the sound. That was no thunder, but something that sounded disturbingly similar to the fly in her nightmare. However, it was much louder than she remembered, and it was coming from various directions…

Tara's eyes widened when she realized that it hadn't been a dream after all. Her heart began to pound in her chest, and a rush of pure adrenaline surged through her system, triggering her instinctive fight-or-flight response, yet she didn't move, not even an inch. She was frozen in terror, rooted to the spot like the trees around her, while the heat inside her flared up so intensely that it blurred her mind and vision. Driven by desperate instincts, her tail rose on its own, and her plump, moist cunt loosened with an eager squelch, her clit jerking out as if to greet the swarm of monstrous insects that finally spilled out of the woods around her.

"Shit, there are so many of them," the young mare whimpered, her heart sinking to her hooves as she counted at least two dozen fat green flies buzzing around her in a disorienting dance. Every single one of them had a visibly bloated abdomen like the one that had landed on her this morning. The entire sickening nightmare flooded back into her mind, from that turgid, meaty maggot squeezing out of its mother to the moment it wriggled into her cunt, eager to join the other one already buried inside her. At the same time, she recalled the intense stimulation and unmatched pleasure that the pair of larvae had brought her, and she clenched her thighs together with a wet squelch and a frustrated whine.

At that moment, said maggots deep inside Tara's womb awoke from their slumber and immediately started squirming with renewed vigor. She didn't know why they became active at the worst possible moment, or what they were actually doing inside her, but they left her no time to ponder either question as they showered her heat-ridden brain with fresh stimulation.

The sudden rush of pleasure left the mare knock-kneed and groaning, shaking from head to hoof just as the first three flies landed on her back. The weight of their surprisingly heavy bodies and the uncomfortable tickle of their clawed, hairy feet was enough to overwhelm her. She collapsed onto the forest floor with a miserable snort, dropping into the muddy dirt and fallen leaves beside the creek before even more flies settled on her hot, brown-furred body, greedily slurping up her sweat with their long black probosci.

"Oh Gods, help me!" Tara wailed as the most enthusiastic of the flies crawled onto her butt and lifted its pulsating abdomen to lay its offspring into her cunt. Another one couldn't even wait to get to her backside, starting to push out its maggot while it still stilted around her furred flank, granting her an unsolicited close-up of the process. Like the petals of a flower, the mother's abdominal chitin parted to reveal a convulsing, wrinkly orifice, splattering juices all over her fur as the armored, dark brown head of its larva emerged from its depths.

Most of the other flies waited their turn with lazily fluttering wings, but three of them joined their companion on her butt, tugging and suckling at her puffy asshole with their legs and mandibles. They were surprisingly gentle, but their palpable interest in her dark, plump pucker made her increasingly worried that one of them would try to crawl inside it. Meanwhile, two more insects slipped between her hind legs and explored her dark brown teats, avidly stroking and rubbing the supple, sensitive tissue around her nipples to add an even weirder tingle to this twisted rush of stimulation.

However, while the swarm of fat, gravid insects upset the mare even more than the single fly this morning, she couldn't help but watch them with uncomfortable curiosity and a growing hint of excitement. She knew exactly what was about to happen. These putrid creatures would lay their brood in her wet, winking cunt, defiling her womb with dozens upon dozens of fat, writhing maggots with all the unspeakable consequences that would entail. But in doing so, they would alleviate her infuriating estrus in a way no regular male ever could, with the most intense, most explosive climaxes of her life. When she also realized that there was nothing she could do to stop them, and that she would never ever bear any foals of her own after these monstrosities were done with her, something finally snapped deep inside her.

Tara let out a deep, resounding neigh when the first slimy, squirming grub slipped against her trembling vulva. Unlike in the morning, however, she did not attempt to cinch her entrance shut. There was no point in fighting her body's natural responses, there was no point in fighting the agitated swarm of flies as even more of them emerged from the woods, and there was no point in fighting her own maddening urges. "Gods forgive me." With an abject whimper, she gave up and embraced her fate, closing her eyes and relaxing her tense muscles.

As the mare slumped on her side, the maggot at her vulva immediately took advantage of her surrender and wiggled into her unprotected channel, stretching her sensitive folds and insides with its fat, bloated body.

Tara got to experience the larva's every twitch and movement as it writhed against her G-spot, and she let out a heated cry when another larva dropped onto her winking clit and gave it a curious pinch. She wasn't prepared in the slightest for two of the squishy worms squirming their way past her equine folds, and together, they pushed her faster toward an orgasm than she wanted to admit.

Meanwhile, more and more of the big green flies migrated to her backside. Were they intrigued by the sounds? The obscene squelching and smacking as the two grubs wormed into her wet pussy? Was it the sight of the larvae disappearing into her pink depths? Or was it simply the scent of her violation, the mix of her musk and arousal, of her pheromones mingling with whatever cocktail the flies produced to rile each other up for the laying? Most likely, it was a combination of all these factors as they swarmed her stretched, plump sex and birthed another half a dozen maggots onto it.

The mare whined and howled, choking on her spit as the larvae attempted to push inside her all at once. Tears streamed down her cheeks as her cunt was invaded by three of the plump, determined maggots at once, her whole body shook and tensed up as they squirmed deeper with unbroken vigor, and she finally succumbed to the lewd onslaught when a particularly impatient larva switched to her other hole instead and crammed itself into her plump, puffy asshole with one slimy shlorp.

Tara came hard. So hard that stars flashed before her eyes, so hard that her holes convulsed violently enough to expel two of the larvae that had just entered her, and so hard that the entire forest resounded with her lustful neigh. Any traveler within earshot would assume that she was having the time of her life, and they would be right. There was not an iota of resistance left inside her as she loudly celebrated her infestation, she shook with overwhelmed pleasure as the maggots her orgasmic contractions had pushed out forced their way back inside her, and she splattered the mud beneath her backside with gushing, gooey squirts of her mare juices as her clenching cunt and asshole eagerly embraced another batch of fat, dirty grubs.

By now, the maggots no longer cared which hole they squeezed into. Both her intestines and her womb offered them the same moist, warm shelter to fatten up in safety, pupate, and finally emerge as beautiful, dazzling green imagos just like their parents. And after today, they would be the only life that would ever come out of her.

The swarm swirling around the mare grew denser and denser by the moment. It seemed as if every single giant fly in this forest had learned about this exceptional opportunity, and some of them were so keen on infesting her with their fat spawn first that they fought each other with angry buzzing and ferocious leg slaps. Not that there was any need to fight, as Tara's insides turned out more than big enough to bear them all, while she was too blissed out to realize the sheer number of larvae she was going to carry.

Once the first maggot of the new batch reached Tara's cervix, she lost it completely. Still stretched and loosened from the initial two grubs, the entrance to her womb offered no resistance to the newest invader, and it had also numbed enough that she didn't pass out from another bloated larva forcing itself through it. Instead, the spike of stimulation abducted her into even happier spheres of bliss, and the brood that followed made sure that she was suspended in her godly high until she could no longer tell seconds from hours.

Tara's orgasmic cries, however, ceased abruptly when one of the flies crawled onto her slender muzzle and plunged something firm and slimy into her open mouth. She opened her eyes with a stunned gag, choking as a sickeningly sweet liquid washed across her tongue and overwhelmed her taste buds. Eyes blurred by tears, she had to blink a few times before she could make out the fly on her snout, which peered back at her with its emotionless, faceted red eyes while it buried its abdomen inside her muzzle. Having already laid its offspring, it fed her what was essentially its amniotic fluid, yet it tasted like rich, divine honey, and she was hooked from her very first sip.

Gulping down her first mouthful of the fly's addictive nectar, the mare immediately felt the craving for more, and she closed her lips around the insect's abdomen to start sucking on it like on a milky teat. It was something her own teats couldn't yet offer, even though a stray maggot and at least five flies swarmed them, squeezing and rubbing them in a futile attempt to elicit a droplet of her milk, only to make her holes gush and clench in an even more furious climax.

While Tara guzzled the fly's delicious slime, two more of its kind clambered onto her muzzle to let her suckle on their ovipositors. Thirsty for more, the mare even glided her tongue into her chitin-clad partners' empty abdomens, squirming and thrashing her tongue around to lap up every last drop in an imitation of their writhing larvae.

Unfortunately, her strength soon failed her. Her tongue's dance slowed, and her body became as heavy as lead. Were the flies paralyzing her? Had she been climaxing so much that she simply had no energy left? She couldn't tell as her lust-broken mind lost its remaining cohesion in the constant assault on her senses. Eyes blank and overflowing with tears, muzzle open and drooling, she stared up at the blue sky above as the swarm of flies enveloped her like a hot, buzzing blanket, making her stew in her own sweat and juices until the ground beneath her turned into wet mud from it.

All the while, the ever-same violent waves of her climax ripped through her, her body shaking, her heart pounding, and her holes convulsing with unceasing vigor as they welcomed maggot after maggot, one by one, dozens, if not hundreds of them into her swelling, fattening guts and womb. If her brain hadn't already snapped from the overstimulation, their incessant squirming and writhing would've broken it for sure.

Tara's orgasmic daze lasted until the sun kissed the horizon. The hours upon hours of depraved fun with the flies and their larvae had left unmistakable marks on her body and deep scars in her mind that would never heal. Even after the last few of the giant green insects departed after a deed well done, it took another half hour for the longest orgasm of her life to ebb. The endless trail of writhing maggots on their way into her hospitable depths made sure of that. However, once the last of the squirmy fly spawn settled inside her colon and her uterus, she slowly came back to her senses. Gasping, heaving, reeling for breath, she found herself covered from neck to tail in mud and sweat and dying of thirst even though she had been lying next to clean, flowing water the entire time.

Already when she bent for the burbling creek, the mare noticed the weight she had gained thanks to the new brood inside her, and a glance at her dirt-encrusted belly left her at a loss for words.

Tara had expected to feel the consequences of her unspeakable encounter with the flies, but she hadn't expected it to leave her with a belly larger than that of a mare right before birth. Not even the most gravid mares carrying twin foals could match her heavy, swollen dome that had to be stuffed with hundreds of fat, bloated maggots. A strange pride overcame her as she realized that she was a mother now, giving life to so many creatures, even though they weren't really her own. Was it a lingering effect of that sweet, intoxicating sap that tainted her mind with these depraved thoughts? Or was she simply accepting her fate as the swarm's warm-blooded brood mother? Either way, this was now her load to bear, and she didn't care where those warm, fuzzy motherly instincts came from as she basked in them with a blissful sigh.

What the mare didn't accept, however, was how dirty she had become. After guzzling half a lake's worth of water, she dragged herself into the cool rivulet and rolled around until she had washed away all the dirt and grime, all the sweat and juices. It obviously couldn't replace a proper bath and scrubbing, but it would do for now.

No longer thirsty, somewhat clean, and still warm and tingly inside from the most unreal afternoon of her life, Tara settled on the largest pile of leaves she could find and let out a contented sigh. Even her infuriating estrus was quenched, and her sore ankle was feeling better after her incident today, so she had a somewhat good feeling that she would finally reach Clover's Brook tomorrow, despite the massive extra load she now had to lug around. But now, as darkness enveloped the calming forest and the stars twinkled above her head, it was once again time for her to sleep, and she dropped off with an exhausted smile on her lips and a big belly full of new life.
