An incubus escapes from Tartarus during estrus season and fucks its way through Ponyville.

An ancient entity has escaped from its confinement within the depths of Tartarus, an entity that feeds on sexual energy. Starved after millennia of imprisonment, it finds the perfect feeding ground: a small village in the foothills of the Celestial Mountains. It is estrus season, and the citizens are all bubbling with lust.

This story includes various fetishes. Some of the more extreme ones are listed here (list to be lengthened later): cum inflation
P.S. Just to be clear, though its pony form is a bat pony, the cover art is not the incubus. I just couldn't make my own art because I don't draw. :derpytongue2:

Chapter 1

A smoky, ghostlike entity weaved in between the trunks of trees as it made its way through the Everfree Forest. It was a moonless night and the forest was pitch black, but it had no difficulty navigating through the lush maze. The sounds of pursuit had long faded behind it as it had outrun the ethereal guards that were meant to apprehend it.

The entity had no name. It had existed for time immemorial, but no mortal had ever thought to formally name it. At times it had been known as "The Drive of Lust," "The Spirit of Desire," or something similar, but it had never considered them to be names so much as titles. It did, however, have a classification; it was an incubus.

Incubi were demons, clouds of masculine essence which fed upon the sexual energy of mortals. The entity supposed that definition made it male, but with its essence depleted by starvation, there was not currently enough for it to form a concrete gender identity.

They could either infiltrate ponies' sleeping minds and feed on their sexuality through wet dreams, or confront them physically and get their gratification that way. Though they could survive millennia at a time without feeding if need be, incubi had to feed regularly to remain strong.

Just like mortals, incubi had their own individual sexual preferences, and this particular incubus was interested in all sexual energies. And it could feel a beacon of those energies on the horizon in front of it. Just at the edge of the forest, it could sense the presence of a lone mare, her need calling to it like a desert oasis.

The incubus finally reached the forest edge and saw a small, lonely cottage. There were many animal presences inside, but they were almost completely drowned out by the powerful floodlight of a mare in estrus. It glided over the grass, unseen in the dark of night, until it came to a window which had been left cracked open. Through the opening, it could smell the mare's intoxicating scent, and it eagerly dove inside without hesitation.

It found itself in a quaint living room, filled with accommodations for various animals, along with a couch and end table. Mostly ignoring the furniture, it floated up to the second floor, bleeding through the bars of the stairway railing. It turned right to make a beeline for the source of the scent. The door was left slightly open, so it slipped through the gap and into the room.

The mare lay asleep on her bed, snuggling with a small white rabbit. Her coat was a beautiful butter-yellow and her mane the pink of a sunset. She was emitting powerful pheromones even in her sleep, and the demon could practically taste her juices already.

The mare turned under the covers and mumbled something. The incubus could sense that she was having a nightmare, but it knew how to change that. Without any further ceremony, its smoky form drifted into her mouth and up her nostrils, entering into the realm of her psyche.

*~*~*

Fluttershy panted as she galloped through the Everfree Forest. Branches and brambles scraped her face and coat as she ran, but she could not stop. She could hear the timberwolves behind her, snarling and growling as they snapped at her heels. Her wings were glued to her sides by fear, but even if she had been able to use them she was too weak of a flyer to escape them in time. She knew it was only a matter of time before they caught her. All that any of them had to do was nip one of her hooves and she would be dead before she even had a chance to stumble.

Suddenly, she gasped as she heard another rustling noise in front of her. It was distant, but it was rapidly coming closer. As it approached, Fluttershy clenched her eyes shut as she waited for the other timberwolf to burst out of the trees in front of her and devour her.

But instead of crushing jaws and sharp teeth, she felt a whoosh of air as the wolf leapt over the top of her. She heard a crack of splintering wood and she opened her eyes and looked behind her. It was not a wolf that had leapt over her, but a pony.

Big Macintosh had just bucked one of the four timberwolves that had been pursuing her to splinters. The other three glared at him defiantly, and moved to attack, but Big Macintosh raised a hoof and punched the one closest to him, shattering it as well. The other two paused, their expressions becoming uncertain. They backed away, and eventually they turned and fled into the forest.

Big Mac turned to Fluttershy, his eyes glowing with a soft, soothing green light. She smiled gratefully at him.

"Thank you, Big Mac," she said as he trotted back towards her. "That was so brave!" He nodded.

"Eeyup," he said in his characteristically deep voice, extending his hoof. "Now you should prob'ly come with me, Miss Fluttershy. Don't want ya ta run inta any more dangerous critters, now do we?"

"No," she said. "I guess not." She took his hoof and he guided her down the path.

They quickly reached the forest edge and trotted out into the sunlight. They were on the edge of Sweet Apple Acres, and the farm's eponymous apple trees stretched from about 50 feet away from the edge of the forest all the way over the green hills into the distance. Big Macintosh led Fluttershy away from the tree line and they stopped beneath an apple tree. She sat down on the shaded grass, and Big Mac did the same.

Fluttershy suddenly found herself thinking extremely naughty thoughts about the stallion in front of her. She loved the way his powerful muscles bulged underneath his coat, the rich, masculine tone of his voice. Not to mention the enormous pair of balls hanging between his hind legs. Her usual shyness seemed to disappear, and she leaned in closer to the stallion.

"Big Mac?" she said demurely, running a hoof affectionately over his muscular chest.

"Eeyup?" he replied. Her teal eyes were half-lidded as they gazed into his glowing green ones.

"I'm thinking that I should show you my appreciation for saving me," she said sultrily. "You know... really make you understand how grateful I am. Does that sound okay?" He gave an almost predatory grin.

"Eeyup." She leaned in closer and closed her eyes as their lips met in a passionate kiss. Big Mac wrapped a hoof around Fluttershy's barrel and pulled her closer as their mouths moved in concert. He sucked lightly on her bottom lip before returning to the rest of her mouth. His tongue then prodded lightly at her lips and she eagerly allowed it access.

His tongue licked up and down the inside of her mouth, running over her teeth and the insides of her cheeks. She wrapped her own hooves around Big Mac's large frame as she used her own tongue to massage the inside of his mouth. Then their fleshy appendages entwined with one another in a lustful embrace, dancing together like two ponies doing the Tango.

She moaned into his mouth as they kissed, and she heard and felt a lusty growl from Big Mac in response. She could feel the warmth growing in her nethers, and her secretions had already begun to coat the grass beneath her hindquarters like morning dew. The fire inside her had to be quenched soon, or she felt she would go insane.

Fluttershy moved her body forward, shifting into a kneeling position. She shivered from the sudden feeling of the air against her wet pussy, which heightened her desire even more. Still kissing Big Macintosh, she gently pushed him forward until he was laying on his back. She could feel a massive pillar of flesh pressing against her belly, the hot pulse moving through it driving her mad with need.

She broke the kiss and reached behind her with one hoof, stroking Big Mac's rock-hard member. She ran her hoof up and down its length, exploring the veiny contours. It was especially large, even for a stallion of his size, but she was confident that she could take it all.

Fluttershy stood up and turned around, presenting herself to the stallion behind her. Her swollen labia dripped with juice, the liquid's powerful scent loudly advertising her desperate need for cock. She turned her head to look behind her and gazed pleadingly at Big Mac.

The stallion sat on his haunches with his legs spread wide, giving Fluttershy a clear view of his equipment. The shaft of his penis was almost as big around as his hoof, and it reached all the way to his breast. The medial ring sat at about the bottom of his ribcage, and the slightly flared head bumped against his chest as the dick bobbed along with his heartbeat.

Beneath the shaft, a huge pair of meaty balls pulsed rhythmically, appearing almost like living organisms in their own right. Networks of prominent veins seemed to cradle them, and they seemed to swell with every heartbeat as they prepared their payload.

Big Mac rose up onto all fours and brought his muzzle near Fluttershy's dripping cunt. He took a deep breath through his nose, inhaling her scent. Fluttershy gasped as he abruptly gave a full-bodied lick from her clit all the way up her slit, making her shiver in pleasure. He then brought his lips closer and began kissing around the labia, occasionally sucking gently on the tender flesh.

Her pussy winked, and she lightly moaned as his tongue rubbed against her clit. Then she winked again, and he wrapped his lips around her clitoris and held it in place. She screamed and her front half dropped to the grass as she was suddenly overwhelmed with pleasure. Her sensitive nub felt every microscopic movement of Big Mac's mouthparts, and every twitch sent waves of euphoria through her.

"Oh, Mac!" she shouted, digging her hooves into the ground. "Anh!" Her body seized and she suddenly came, and Big Mac's muzzle became drenched as it was sprayed with Fluttershy's climax. He immediately began drinking her marecum, eagerly and loudly slurping it up. He growled with barely restrained lust, and the vibration sent pleasure through her even as she came down from her orgasm.

Once she had stopped gushing, he reared up and placed his forehooves on her rump. Unable to hold himself back any longer, he shoved his enormous shaft straight into Fluttershy's cunt.

Mac's thick cock slid easily into her well-lubricated tunnel, spreading her hind legs as wide as they would go. Her tight walls welcomed his presence, hugging his shaft snugly. As the member sank deeper inside her, she panted and moaned in ecstasy.

He quickly bottomed out, the head of his penis pressing against her cervix. His shaft also happened to be just the right length, and his giant balls made a barely audible slap as they smacked against the small teats just in front of her vulva. She could hear the seed churning within them, just waiting to fill her.

Big Mac pulled back, withdrawing his dick and leaving Fluttershy with a terrible emptiness inside. But the emptiness was brief as he thrust back into her hard, smacking against her rump and making her moan again. He continued this pattern, gradually speeding up his pace until he was smacking into Fluttershy's cheeks like a metronome. His balls swung back and forth as he thrusted, occasionally slapping her teats.

Soon, his thrusts became slightly erratic and his breathing heavy, and Fluttershy could tell that he was approaching his own climax. She did her best to expedite it, rhythmically clenching her vaginal muscles in time with his thrusts.

He grunted and hilted himself inside her, and his cock pressed up to her cervix once again. The head flared and formed a cozy plug inside of her, and his balls twitched as he shot a load of hot jizz directly into her womb.

The warmth of his cum blossomed inside of her as it filled her uterus, and she clenched her muscles in an attempt to milk as much out of him as possible. It came in repeated spurts, each one seemingly larger than the last. The stallion's seed filled her to the brim, and still it kept coming. She moaned as her womb filled up completely with cum and began to expand. It stretched and grew as she was filled more and more, and just as the deluge of cum started to abate, she felt her belly ballooning out.

Finally, Big Mac shot his last few spurts of seed, and he laid on her back for a moment. When his flare had gone down a bit, he pulled back, his softening cock falling out of her with a wet pop.

No longer held up by Mac's shaft, Fluttershy's rump dropped to the ground, the stallion's seed leaking out of her gaping pussy onto the grass. She turned on her side, her eyes growing heavy. Big Macintosh knelt down and laid next to her, wrapping his hooves around her barrel. He lightly kissed the back of her neck and snuggled up close to her, rubbing a hoof tenderly over her slightly distended belly. He held her close as the world around her slowly turned fuzzy and she fell into a peaceful sleep.

*~*~*

The incubus rode Fluttershy's contented sigh like a wave as he exited her body. Now a much larger cloud than he was before, he hovered for a moment above her sleeping form. A large stain had darkened the blanket over her crotch, and she smelled strongly of sex.

The incubus was much more powerful than before, and with his feeding his masculinity had returned. He had very much enjoyed his experience with Fluttershy. The mare had been awash in pent-up lust and her powerful energy was enough to sustain him for quite a while. He considered that he ought to return to her at some point in the future.

He floated down to hover above the stain in the blanket, taking a moment to enjoy the sweet aroma. But then he sensed that she was waking up. He forced himself to leave, gliding out of her bedroom through the open door and then out the window into the night.

Fluttershy awoke, her eyes creaking open to reveal her dark bedroom. She felt a warm stickiness around her hindquarters and realized that she had climaxed in her sleep.

Aw, she thought. It was only a dream. But it was a pretty good dream.

She smiled contently as she cuddled with the sleeping Angel, her body much more relaxed than before. She settled into her bed, hoping to dream of more stallions.
