Chapter 1

In the land of Equestria, most bat ponies were fairly simple, elegant creatures, widely considered to be nothing more then slightly more brooding and uppity variants of pegasi as they flitted about in the sky and went about their business.

What most ponies did not know however was that there were actually several different types of bat pony, and the ones that flitted about in the sky and made brooding poems were just one of the many types that had mostly died out in the years following the banishment of Luna to the moon. Not all of them had gone extinct however, and some of them were even thriving in the new civilized world that had followed after Luna had returned.

She was one of the lucky ones. Almost as graceful as her kin, but seeming much more bestial in her appearance. Silent, strong, deadly. Her name was Jacky Bloodfang. Nobody knew if that was her actual name or just a moniker, and while most people who gave themselves such names went on to join rock bands and commit to a goth lifestyle, she had earned the name on the battlefields and war zones where colorful ponies had no place.

Nobody had dared to call her name edgy for fear of their throat being ripped out. Jacky was a killer through and through, darting about atop wings, hoof and axe blows raining down on her foes to soften them up before her sharp fangs made short work of their throats.

She was a revenant, a relic of an age where things had been much more simple and strength had been the only deciding factor in whether or not you got to eat. And what was it then, that this black furred monster with the fangs and the crimson eyes that sent fear shooting into the hearts of almost all who beheld her was up to on this fine summer morning?

Well that was simple. It was spa day.

The little bell over the front entrance to the shop gave a little tingle as she squeezed her well-muscled form through the doorway. She had been on a long campaign, away from the comforts of home. Her gray mane was a mess, blending the red streaks that were spread across it together until her mane was an unreadable mess of colors and tangles.

The little mare behind the counter looked up at the hulking mass of muscles forged in war and fangs forged in blood before her. She was a young, light green pegasus mare with a single flower pushed behind her ear, and she timidly stared down at the clipboard before her, then back up to the hulking monster.

“Miss Jacky?”

Jacky smiled down at her, showing off teeth like knives and fangs like daggers.

“Yes, I’m here for my appointment.” Her voice was that of a mare, nobody could agrue that, but there was no warmth or life to it. It was as though she had clawed her way out of the grave, but somehow it was still a commanding voice, the kind of voice that turned the blood in your veins into ice.

The little mare behind the wooden counter nodded, then waved a hoof towards the set of double doors that led into the spa proper.

“The spa is that way, I’ll just get your slippers.”

“Slippers?” Jacky asked, a low growl in her voice that she hadn’t intended.

“Yes. They have a special grip on them to keep you safe on the floor. They’re complimentary!”

The mare turned, busy digging through a box behind the counter. Jacky tried to not loom too threateningly behind her and instead examined the small waiting room. A waiting room in a spa was a bit of an oddity, but this was one of the best spas, so it made sense they might not always have enough room for everyone.

The room was small, and there were only four stairs stacked up against the back wall, but between them was a table piled high with books and magazines. She wandered over to them, her keen eyes scanning over them. None of them caught her attention until the very last one, which seemed to be a magazine about a pen and paper roleplaying game.

She plucked the book up and briefly stared over the cover, a picture of a heroic knight baring down upon some great beast. In her line of work she’d met a lot of ponies that had heroic ideas and ideals, and a smirk briefly spread onto her face as she remembered how most of them had died shitting themselves or crumpled after their rations ran out and dysentery set in.

She didn’t find it funny they were dead, more in the fact that heroic ideals and ideas seemed to only be good for getting ponies killed, and yet they never seemed to die out. There was always another white knight ready to die for something stupid. Jacky was a monster. It wasn’t pretty, she didn’t get statues or stories, but in the end she was the last one standing.

A soft cough from behind the counter dragged her from out of thinking about such things and she focused back on the present moment, the mare holding a pair of four white fluffy slippers out towards her. She had to stretch them slightly to get them over her hooves, but they fit, and they felt nice. It was as though she was wearing four baby bunnies on her limbs.

Now that she had her fluffy white slippers which were meant to protect her from the floor, she strode her way through the set of double doors and into the spa proper, announcing her presence with all the confidence of someone that knew they could kill everyone in the room without issue.

The spa was a lot larger then she had thought it was going to be. Firstly, there was a large swimming pool that took up the vast majority of the room, then in front of that there were two round brass bath tubs set into the floor a distance away-

The smell of chlorine hit her nostrils and she was too lost in a laughing fit for a few moments to take in the rest of the room as she remembered how Lord Sunny Standard had died. They’d been crouched in a muddy shit hole for weeks, he’d sent his squire home after a cunt of a zebra had given him a nasty wound, and- And-

She had tears in her eyes as she remembered. This ball, with a bunch of holes in it, had landed next to them, spewing this purple smoke everywhere that smelled like a swimming bath. Sunny Standard had coughed, laughed to himself, and said “These zebras are throwing incense at us. Are they trying to scent us to death?”

And then he had coughed up the inside of his own lungs.

Well. It was funny when she remembered it. She wiped the tears from her eyes and realized that a small brown stallion with kind blue eyes was staring up at her.

“Miss? Miss? Hello, Miss? Are you okay?”

Jacky Bloodfang gazed down at the stallion, who was wearing a white spa outfit, and she realized that this is what stallions these days looked like. He didn’t look hard, he didn’t look wiry, he looked girly, and soft like a peach. She didn’t judge him for that however.

Lifting one of the fluffy slippers up to her face she gently wiped the tears from the corners of her eyes and gave him a gentle smile. “Sorry. I was just remembering something funny. Do you work here?”

The stallion nodded, “I do. I’m going to be your spa worker today. So if you want a massage, a wash, or any of the other treatments included in your package, don’t hesitate to ask!”

For a moment, she was lost again. Jacky had been told that she needed to enjoy life more and do more “mare” things. Now she was here, she didn’t actually know what it was that she wanted however.

Well.

“Ah… Do you do teeth whitening?”

The stallion looked confused for a second. His brow furrowed beneath his long mane, which was the color of red grapes.

“Unfortunately not ma’am. That’s more of a dentist thing.”

Jacky let her disappointment show upon her face. “I see. But I really want my teeth cleaned. Are you sure that’s not something you can provide? Surely you must have toothpaste and some brushes, no?”

For his part, the stallion, who she had only just now cared to discover was called Viny Heights, looked very confused for a few moments, before giving a nod. “If Ma’am wishes it, I am sure I can find something.”

She smiled, “Thank you very much, Viny. And I would love a wing massage to go with it.”

He nodded, but was clearly very nervous being next to a creature that could rip his head off, which was a very valid thing to be concerned about.

The next five minutes was spent waiting for the stallion to gather the needed things as she quickly discovered the massage benches had an issue. They were far too small for her giant frame, her limbs still touching the floor even as she lay across it, and her head far too big to easily fit through the hole that it had been designed for.

In the end, she had to lay herself out across the faux leather massage bench like she was some kind of animal skin rug. The mental image amused her long enough for Viny to return with a simple plastic toothbrush and a tube of toothpaste. She scanned her crimson eyes over to him and peered directly into his soul.

“Alright Viny. Show me how you treat a beast.” She gave him a wink, she couldn’t be sure why, but it seemed to fluster him and that was funny to her.

It was even funnier when she rolled out her tongue over her teeth, dangling down her lips like some kind of dying eel, seemingly far too big for her mouth. This only seemed to fluster him even more. Here she was, a monster that could kill him with as much effort as swatting a fly, and he was freaking out like he was about to ask her to prom.

She could hear his heart beat picking up, pumping blood to his body and face. Gosh, she wasn’t into stallions, but normally the few that dared to hit on her were the hulking, fighting, fucking and cursing kind. Having some little twink in a spa uniform getting flustered over here was just… Something else.

She closed her eyes as he began to work at the first of her fangs, letting her mind take her away to far away battlegrounds and memories. Memories of all the times her fangs had punched through armor and drained the lifeblood of her foes. Memories of all the cunts she had served with, memories of countless foes she cared little to remember, and the few she did.

One stallion had tried drinking poison, then attempted to get her to drink his blood in order to bring her down. If she wasn’t so good at tasting such things and hadn’t spat him back out, it might have worked too…

She was drawn back to the present moment by just how gentle the stallion was being with her fangs, treating each one as if it were some precious jewel. Jacky had half a mind to growl out something to him about not needing to be gentle, but it was… Nice.

Battle. Battle could wait. This moment was worth focusing on. This stallion with the thundering heart beat that was treating a beast like her so gently. He was sweet. She didn’t care for sweat, but it did make a nice change from her normal company.

He gently brushed down each of her fangs, pressing the brush into her gum tissue. She really hoped he didn’t pull any bits of pony flesh from out of her teeth, that would be somewhat awkward, but thankfully she had flossed since her last battle.

Once he was done with brushing her teeth, his heart beat picked up, going even faster, beating like a war drum in her chest.

“So… What is it you do for a living miss?” The timid stallion asked tentatively, moving the brush away and presenting her a bucket to spit into. She rolled her tongue back in and did the ugliest and least feminine spit she could into the bucket, almost laughing as this only made his heart go faster.

Jacky didn’t do small talk, but she wanted to see where this would go. She licked her tongue over her teeth and then stretched her massive leathery wings out behind her. “I’m a mercenary. I’ve killed dozens of ponies and other creatures for coin.”

She wasn’t shocked when his heart picked up, though with this weird stallion she couldn’t be sure whether it was fear, or he actually found the idea endearing.

His bright blue eyes made it clear, they were sparkling with excitement. Gosh, this cutie really was some kind of freak.

“Really? What kind of weapon do you use?”

“An axe,” She moved up a hoof to her throat and made a slicing motion, “lopped their heads clean off, though sometimes I also use my fangs.”

The stallion had moved behind her now, his gloved hooves slick with some kind of substance that smelled of lavender and felt pretty good against her wings as he got to work.

“That’s so cool. So do you like, drink blood?”

She listened intently to his heart beat, “Yeah. It tastes really good to me.” The little freak’s heart beat picked up even now, and it wasn’t due to fear either, she could see him blushing from the corner of her eye.

“O-oh! They… I… “

“Spit it out, colt.”

“Sorry Ma’am. I was just wondering how that works.”

She raised an eyebrow, “Why, do you wish to find out?” The little fucker’s face turned red beneath his fur. Holy fuck, this was great.

“I-I n-No M-ma’am. I just read a lot of stories and I always wondered.”

His little hooves were shaking with excitement. It was really hard to stifle a laugh as she spoke. “Well, why wonder when you can find out. It’s not as graceful as the stories, but personally I think you’d look really fetching with a neck scar, and maybe, maybe, I can sate some of your urges in return.” She finished the last part with a seductive growl.

The poor thing was practically dying. He’d barely even started the massage and now he was struggling to even string a sentence together.

“M-m-ma’am it’s not… It’s not proper… I’d get… fired for…”

“Come now, nobody would have to know. And I never even mentioned sex, you cheeky little thing. Just… Favors for favors. You said you’d wondered right, well why don’t I show you?”

He swallowed a lump in his soft little throat and then fixed those pretty blue eyes on her with as much resolve as his body could muster.

“I-Is it safe?” He asked, and she let out a soft laugh that sang through the air like a siren song heralding doom and destruction.

“Safe? Almost completely, as long as you don’t have a heart condition. My saliva contains an anti-bacterial and clotting agent to keep my little snacks alive.”

The face he pulled in that instant was a picture. It was clear he was really fighting with himself over this one, but after a few moments he gave a stiff nod.
“We could u-use one of the… steam rooms. Or one of the rooms for-for extended visits.”

She growled softly to herself, then rose up to her full height. Her wings hadn’t been massaged properly in the slightest, but she was really enjoying herself. This was going to be fun.

-

The small brown stallion really was a cute one. As she had previously explained all the stallions she interacted with were hard forged muscles or wiry and swift. This one simply reminded her of a peach, easy to bruise and she was certain that she would be able to kill him in a second if she so wished.

Luckily for Viny Heights, she didn't wish that. She was a mercenary and a creature designed to kill, but she was also a professional and professionals had standards.

Unfortunately for Viny she was also a lesbian for the most part and so she was going to have to make things interesting. She could hear his heart fluttering away within his chest like a bird in a cage and she used that sound to dredge herself away from the memories and actions of wars long since passed, doing her best to relax as she lay herself sideways across the Queen sized bed. Unfortunately it was still too small for her, leaving her rear and head sticking over the edge.

Viny was clearly eager to get behind her and give his best attempt at breeding her, but she had other plans in mind.

"The first thing I want you to do, my little toy, is give me a kiss."

Viny nodded eagerly, blushing awkwardly, but that awkwardness was being pushed away by the hormones currently flooding through his blood. He was brave now, leaning in to kiss her on the lips and staring into her crimson eyes and staring deep into her crimson eyes and freezing up as he stared into her eyes and they stared back into him. Someone had thrown a wrench right into the workings of his mind, bringing it all crashing and grinding to a halt.

He was stuck. The thoughts inside his mind that had been fizzing and popping so excitedly coming to a stop as he stared at her with a completely blank expression. She had bore her will down upon him like a great hammer and he had crumpled under it.

"You like me, don't you Viny? Be honest with me." She stared directly.

"I like you. Yes. I like you a lot," His voice droned without the slightest hint of emotion.

"You want to fuck me don't you, Viny? You want to fuck Mistress Jacky, don't you?"

"Yes. I want to fuck you Mistress Jacky."

The stallion wasn't lying either. It might have seemed like some mere hypnotic trick, and while he was enthralled to her will, he was speaking directly from his subconscious.

"You'd do almost anything for me, right?" She cooed, bringing her head closer to his and maintaining the perfect eye contact.

"Yes! I'd do anything for you Mistress Jacky."

Beneath the stallion, he was growing excited from this. It should be noted that he was almost still completely aware of what was happening even under her control, and in response the cute brown stallion with the mane and tail that were the colour of red grapes got aroused.

She stared even more intently into his rich, light blue eyes and smirked slightly as his member perked to life beneath him, slowly sliding from out of his sheath. The eyes were the windows into the soul it had been said, and it seemed the firmer she gripped this stallion's soul in her clutches, the more rapidly aroused he became.

"Well that's good." Jacky began with a dangerous purr to her voice, "Because I'm quite parched. How's about you give me half a pint of your blood and I give you the most intense orgasm you've ever had in your life?" She proposed, spilling her long tongue from within her mouth and dragging it over her parched lips to illustrate the point.

She really hoped this stallion was as much of a freak as she had been hoping, and if Jim standing at full mast and twitching excitedly at her words was any indication, then she had been right on the mark.

"Yes!" The stallion said excitedly.

Jacky gave a seductive growl that came out more like a regular growl, "Yes what, snack?"

"Yes! You can have some of my blood Mistress Jacky."

Bingo. That was all she needed to hear.

The expression that spread across her face could only be described as demonic. The smile itself would give some ponies nightmares alone, looking like a wound slowly becoming un-stitched as she leaned in close to the pony and placed his hooves on the bed, firmly keeping him restrained and their focus solely on her.

“Now,” Jacky began, “I want you to picture yourself at my rear, with your hooves gripped around my flank firmly…. How does that sound, snack?”

At this point she was also bringing the full weight of her willpower to bare now that she knew the stallion liked it, and it managed to draw a soft moan and an eager nod from the stallion, his hind legs shaking as he was clearly very eager to plow his hips back and forth, bury that aching length deep inside of her and fill her with his seed.

She was more then happy to add fuel to the fires of his fantasy. “Mmm, You can go ahead and thrust for me now snack. I want you to plow that length deep into my aching cunt. I’m a large mare, but I assure you, I can grip and milk your length like nothing you’ve ever had before.”

The stallion groaned happily, thrusting his hips greedily against the air in a desperate motion, as if he was fucking her, and the way that he moaned it certainly seemed like he was locked deep into that fantasy. She didn’t touch his cock, she simply stared directly into his soul and let out little moans and coos like she was egging him on.

She was drawing him deeper, pulling him into the fantasy of getting to fuck her until he would eventually lose himself to it. And she couldn’t wait, watching the focus slowly drain out of his eyes as he lost himself in a fantasy that he himself was sustaining.

“I bet my cunt feels like heaven around your cock, doesn’t it my sweet little snack… Gripping and squeezing you with those precise motions, pulling you deeper, driving you to thrust even harder into me and just give me everything that you have… I bet it feels good right? My flank must make a loud smack when your hips bounce off it, huh stud?”

The noise that the stallion made was somewhere between a squeak and a moan, but the focus was totally gone from his eyes. He was lost in the fantasy, and it took everything she had to keep a smirk from off of her face. His member was throbbing desperately between his legs, practically begging for attention that she would never give it.

Focusing herself on her little snack’s face again, she grinned even wider, showing off every single one of her fangs, shining softly in the light like daggers waiting to sink themselves into some poor unsuspecting target, and the stallion loved it. He must have been a real freak because he had willingly given into the hypnosis completely, losing himself deep in her control and loving every second of it.

“I bet it feels good, right? Fucking a big bad bitch like me, you like that, don’t you freak? You love the idea of knocking me up and filling me with your foals.”

He didn’t respond, but the groan of pleasure he made was more then enough confirmation. “And you love how my pussy grips and squeezes around your length, begging you to just absolutely destroy me, right?”

Another groan from the stallion, and then suddenly his member twitched excitedly and a thick blob of pre leaked from the head of his cock and dribbled onto the floor. She failed to hide the smirk from her face. This was just too delicious, watching his face twist and contort with pleasure while she did nothing but keep him locked deep in a trance and focused on fantasies of plowing her.

She was going to make him cum like this, before it had just been a cheeky idea at the back of her mind, but now it was a certainty. She was going to make him climax harder then he had ever done so before without so much as laying a hoof on him, simply because it amused and distracted her from the memories of war and violence.

“I bet you want to cum so bad, don’t you? I bet it would feel so good to bury yourself deep in my gripping pussy and just empty everything you have into me right? Doesn’t that sound good to you? How much do you think you have to give, you think you’re going to knock me up? How bad do you want it?”

Viny let out a loud grunt in response, but he wasn’t able to form words. That was fine, she didn’t need him to be able to form words. Her red eyes were still firmly locked onto the very core of his being, and he was firmly thrusting his hips against the air like he was fully intent on knocking it up.

Past a point it seemed like his hips might even turn into a blur with how hard he was going at it. He was giving it all, just to knock up an imagined version of her, and as much as she hated to admit it, that was really fucking hot, and she could feel her snatch starting to get moist from it.

She still wasn’t going to let him near it however, this was simply too much fun.

“Now, no cumming until I say so you needy little thing. Before you even think about knocking me up, I want you to give me a kiss… Understand?”

He gave an eager nod and Jacky turned her head to the side, leaning in and practically swallowing his muzzle up as she deeply began to french kiss him.

Her long tongue drove forward from out of her maw and into his mouth, swirling and searching around inside of it, using him like her plaything, which with how deep he was under her spell was all he was now.

Her tongue was pointed, and perfect for getting into every inch of his mouth, marking it as hers and ensuring that he knew it. She pulled him deeper into the kiss and made sure that her hypnotic focus was perfect as she pushed her tongue forward and slipped it down his throat.

It was large enough to create a delicious looking bulge in his throat, making his moans turn into strange garbled noises that made her tingle excitedly as she used his throat like it was her personal toy. Her eyes were starting to feel tired, and she was meant to be relaxing on her break….

This was certainly relaxing, but she needed to hurry her snack up. She leaned further into the kiss and began to swirl her tongue around inside his throat, causing it to bulge out obscenely as the stallion rapidly breathed through his nose, then gently tried to pull away from the kiss as he began to choke.

Jacky put her fangs on full display. His heart was thudding a rapid rhythm as she slowly pulled her tongue from out of his throat, leaving a thick string of saliva behind as his member throbbed and leaked beneath him. He must have been so needy for his climax, and she was going to given it to him… After she had taken what she wanted.

She reared her head back, opening her mouth wide and showing him the razor sharp teeth.

“Cum.” She demanded simply, then dropped her focus as she launched her head forward.

The stallion cried out, the mental image of being buried deep within her snatch shattering, but the waves of pleasure didn’t fade. His cock throbbed and twitched, then began to fire thick ropes of his seed all over the ground as Jacky’s teeth punched into his neck and filled with his delicious lifeblood.

His life essence spilled onto the ground in thick ropes as his life blood flowed into her, the stallion giving everything he had before collapsing against her.

It would have been easy for Jacky to take everything from him in that moment, but of course she didn’t, simply drinking a small sample that he’d regenerate after a month and a bit, then allowing him to collapse against the bed while she stared at the mess that he had made all over the floor.

He must have been really excited over that fantasy.

And now he was napping peacefully next to her, while she gently licked at his wound, the clotting agent in her saliva ensuring that he was kept safe.

This spa stuff was actually pretty relaxing, it turned out. She could get used to this.
