Prologue: Revelation

It’s funny how at one moment, your life could change drastically. You built up your career in becoming a doctor. Saving people’s lives was something you had a passion ever since you were a little boy. Your parents were proud of your decision and supported you every step of the way and not a day goes by that cease to thank them. Being a doctor, fitness was also important to you since you’d be working different hospital rooms on different rooms.

And things seemed to be going great for you and the people you’ve helped so far… until one day, all your dreams came crashing down when you got in an accident while you were out mountain climbing. You can still remember all the jagged edges you hit on the way down when your hand slipped. When you crashed on the rocks below, your vision went black yet it didn’t feel like you were dead. What was going on?

As your eyes opened, you were greeted by a humanoid equine creature. She was white and voluptuous to boot. And she wore this beautiful faded blue dress golden trims and the dress itself made her look like a Greek goddess. Her mane had four colors and flowed almost like a sparkling river. Yet, the biggest thing about her was the vibes she gave off, warm and welcoming. She introduced herself as Princess Celestia, the ruler of this foreign land known as Equestria, which is your brand new home.

Due to your profession, you didn’t have to look far and long to find employment. Redheart at Ponyville Hospital welcomed you to the team due to your knowledge. Despite the slight differences of biology between humans and ponies, their human-like form made adapting your knowledge a little easier than you thought.

One day, after your shift was over, it was almost evening and you decided to visit the local Ponyville Pub for a couple of drinks. Their apple cider was a perfectly balanced mix of tart and sweet, refreshing after a long work week. Caring for sick patients was rewarding and all, but all that hard work left you exhausted. So far, you’ve had about half a cup of apple cider.

“Phew, I needed that,” you said, setting down your glass.

“Another tough day at the hospital, huh?” the bartender stallion asked.

“It is what it is, sir.” you shot back. “But I wouldn’t have it any other way. And who knows, one of these days, I might actually achieve my #1 goal.”

“And what goal would that be?”

“The day I create a medicine that will cure cancer… for good. I haven’t found a cure yet, but one of these days, I’m gonna do it,” you said before chugging down some more apple cider.

“Well, you just keep on trying. You never know when you’ll hit a breakthrough,” the bartender said, crossing his arms with a smirk.

Suddenly, the door to the pub opens up and in walks the pub’s favorite customer: the ever-frustrated Berry Punch.

“Heya, Berry. Let me guess, you’ll have the usual?” the bartender asked.

“You guessed it hot stuff,” she said, taking her seat two chairs across from you. Your eyes glanced over at Berry, curious of what was troubling her. She had a look of calm that was hiding a sense of unease. Bit by bit, it ate away at her. It wasn’t until long before she noticed you looking at her and let out a slight chuckle. “You getting a view over there, sweet stuff?” she asked teasingly.

“Oh, uhh… sorry about that,” you said, looking away. “My mind drifted a bit.”

“I’ll bet it did,” she replied. The bartender came up to her with a tall glass of shiraz wine.

“There you go, Berry,” he said before putting the wine bottle away. Berry grabbed her glass and took small sips. Her face scrunched from the strong taste and then shook her head.

“WOO! That’s strong! That’s the good stuff,” she exclaimed before taking more sips of it. Your concerns grew when she tried to drink the whole cup in one go and there was a lot of wine poured into the glass.

“Uh… Berry, was it? I don’t think it’s a good idea to drink all that wine in one go. You might want to take it easy,” you implied. Berry stopped for only a brief moment.

“Aww, you’re such a sweetheart. But I can take it, I’m a big mare,” she insisted with a wink while sticking her tongue out. “I just like a good few pints of cider.”

“Cider? Shiraz is pretty strong wine, I’d hardly call it cider at all,” you said.

“Really? I haven’t noticed,” she said in her slurred tone. Berry chugged the rest of her wine down and slammed her glass down on the counter. “Come on now, hit me with another big glass and fill it up to the top!”

“Only if your bit pouch isn’t empty,” the bartender said. Berry got a little too persistent and climbed onto the counter with her face all flushed and with a smile on her face. “I think you may have a problem, ma’am.”

“Aww come on, are you sure you don’t wanna… work something out?” she asked, giving the bartender a sexy pose, sitting on the counter and lifting her leg up in the air.

“O...kay, I that one shot of shiraz wine was more than enough for you. I’m going to have to ask you to leave.”

“Come on, don’t you want this fine flank of mine,” Berry asked, still drunk. You went and intervened, getting Berry off the counter. “Your eyes tell me all.”

“Whoa there, let’s not start an even bigger scene than it already is,” you said. But Berry didn’t pay you any mind.

“Berry please, get a hold of yourself! I am so sorry for her behavior. I-I’d be glad to pay for her bill and my own if that’s alright,” you offered the bartender.

“I dunno, her bill is pretty hefty. With the addition of what you just had, the total would come down to 425 bits.

“Yeesh. She does have a problem.” You thought to yourself. “But, with all the patients I’ve cared for, I guess it wouldn’t hurt to make some room in my bit pouch.” You paid off her bill and yours. “There you go, I hope that’ll cover it.”

Just as you were about to walk away, Berry’s gaze slowly turned towards you. There was something off about the way she looked at you, unnerving and disturbing. It was the type of look that a wolf would give their prey when they were about to attack. You did your best to keep calm, not knowing what would happen.

“Well look at you, filling out my bill the way you did just now. I say you deserve a big reward for helping out a mare in need,” she said, pressing herself onto you.

“Uh… that’s okay, that won’t be necessary. You just take it easy, Ma’am.” you said. However, Berry’s amused expression changed and she got more annoyed.

“Oh, for crying out loud, COME HERE, YOU!” Before you could blink, she pounced, tackling you to the floor. The patrons gathered around as Berry punch pinned you to the floor. Some of them left out of fear. “I’ve waited long enough and I’m getting the relief I’m craving one way or another and you’re gonna like it!”

“Ma’am, please! Why are you acting this way?” you asked, a bit panicked and scared.

“Why am I acting this way? WHY am I acting this way? Between the stressful day at work I’ve had to deal with, coupled with the burning feeling in my tender loins recently, I JUST WANT WANT IT ALL TO GO AWAY!!! So you’re gonna come with me to MY house and YOU’RE GONNA GET WHAT’S COMING TO YOU!”

With a mighty grip on your shirt collar, Berry dragged you outside and toward her house. In your head, you were mentally writing out your will and praying to Celestia that you wouldn’t have to worry about getting killed. And if you did, you prayed it wouldn’t be painful.

You two finally went inside and Berry led you up to her room. With a swift movement, she threw you onto her bed. Even as a doctor, you were amazed at equestrian strength. Compared to regular women, Berry could put them to shame.

“B-Berry, what the hell are you doing?!”

“Don’t pretend you don’t know, sexy. I’m about to fuck the shit out of you,” Berry said.

“W-Wa-Wait, I never wanted this!”

“Well,” Her gaze drifted down to your crotch. She saw that your member was at full mast. With a lick of her lips, she started to rub it, causing you to spasm about. “Your anatomy seems to tell me otherwise.”

“Damn it, she’s got me.” You thought to yourself. “But, this is gonna end in pain.”

Slowly, she removed her shirt and long skirt. From what you could guess by her bra, she was a good D-Cup size. Even more so, your nose was beset by a musky scent. If the small damp spot on her panties were any indication, she was clearly aroused and very hungry for sex. Putting two and two together, she was clearly in heat or estrus as it was known in Equestria. Before you knew it, Berry straight up ripped your shirt off, exposing your bare chest to her.

“My my, such eye candy you are.” She purred before doing the same to your jeans, letting your cock stand tall and proud. From the look on her face, she was clearly surprised and hungry for your monster meat sausage. “Hmmm, you’re quite gifted… for a hairless monkey.”

“Okay, first of all, I take offense to being called hairless monk-OHMOTHEROFGODDAMN!”

Then and there, Berry started slobbering on your erection and started licking the tip while stroking the base of your cock furiously. The sensation of her soft hands merciless jerking you off felt so good, you let out a groan.

“Yes, that’s right. Beg me for more. Show me how badly you really want me. You want to feel my hot pussy swallow your big dick?” she asked, smirking confidently. As much as you were fearing for your life, there was an aura of arousal washing over you.

Your hands gripped the bed sheets tightly, unable to control your lust as is builds up gradually. Soon enough, you found yourself giving into your desires as your endurance reached its limit and you blew a big load in her mouth. Never in your life did you experience something as enjoyable of that sort. As your brain processed what to think, it defaulted to three words: pleasure, joy, and lust.

“Wow, look how much you came from just a blowjob. And you’re still hard, too. Care to move onto the next step… or shall we skip to the main event?” Berry asked, lifting her ass up in the air and wiggling it left and right.

“Don’t you think we’re going a bit to fast? The spirit is willing to press on, but the flesh is spongy and bruised.”

“Oh no, we’re not. I’m calling the shots mister.” Much to your surprise, the removal of her remaining garments displayed her raw and unfiltered beauty in full view to you. “Now then…” the lust-driven mare climbed over you and positioned her dripping marehood straight over your face and sat down. “...Get to slurping, lover boy.”

You’ve gotten this far, you might as well go the extra mile. Wasting no time, you slurped up Berry’s sweet and sour juices from her pussy just as she asked. The drunken dominant mare moaned loudly and ground her hips on your face. With little room for maneuverability, you stuck your tongue in her moist sex.

“Mmm! Oh yeah! Stick that tongue inside my walls! Slurp up my juices like you want ‘em!” she moaned with a sultry growl. When you touched her g-spot, that triggered her lust to go into overdrive. Vigorously, she kept on grinding her pussy into your face. Bit by bit, you’ve found yourself running low on air. The only way you were going to get a respite was to please the horny mare. Focusing exclusively on her sensitive g-spot, you drove the mare to orgasm in a short amount of time. Her hips clamped around your head as they gyrated against your face, soaking you with her essence. Shortly after, she fell back and allowed you a much needed breath of air.

“Holy shit!” you gasped as you gulped some much needed air. As you looked at a recovering Berry Punch, she faced you with your newly erect spear prodding her slit. Letting gravity do the rest, she impaled herself on your cock. Though you looked at vaginas plenty of times throughout your career, never did you have such intimate contact with them. It was the first time you’ve experienced the pleasures of the flesh in such a way and did it feel so good.

“Buckle up, mister.” She growled as she gripped your shoulders, drawing a bit of blood. “You’re taking me for a ride whether you like it or not!”

With tremendous force and speed, she bounced up and down your dick. Every bounce not only made you feel great pleasure but brought pain to your pelvis. Your mind was torn between whether to lose itself in the bliss or to worry about any of your bones breaking. Lots of things coursed through your mind. Why would a mare in estrus behave so unusually rabid? They normally kept it all under control, down to only showing slight discomfort. There had to have been some outside force at work. It was not natural but it felt good at the same time, being your first time and all that.

“OH CELESTIA YES! I NEEDED DICK SO BAD!” She howled as she rode you ever so forcefully. “I DON’T CARE IF IT IS A HUMAN’S! OH YES! YES! YEEEESSSSS!!!”

In order to save your pelvis from getting turned to mush, you grabbed a hold of Berry’s hips, held her in place and pumped your dick deeper inside her pussy. Berry didn’t object to your taking control and kept moaning wildly and screaming in pleasure. You egged it on with hard smacks to Berry’s ass, driving her even more crazy.

With this combined effort, you could feel your ballsack building up pressure . “B-Berry, I’m… I’m gonna cum!” you grunted.

“THEN HURRY THE FUCK UP! SHOOT IT ALL INSIDE ME!!! BREED ME SILLY!” she howled, pushing her hands down on your chest. Bracing yourself, you gave her a few more mighty thrusts before you hit your limit. Hilting yourself, your cock quivered as it filled Berry’s womb with your hot cum. The rush, the ecstacy, it was something that was alien to you. As you became lost in the bliss of your orgasm, you felt your body grow limp and your vision going to black. All there was before your eyes was a pitch black void, no feeling whatsoever.

Your eyes slowly opened to a pristine white room. Immediately, your ears caught the notice of a rhythmic beep. You groaned sitting yourself up and saw that you were in a hospital room… with Princess Celestia standing at your bedside.

“Princess, wha… what happened, where am I?” you asked, calmly.

“You’re in the Canterlot Castle Infirmary. You collapsed after your… private moment with Berry Punch earlier. Berry tried to wake you up, but she panicked and asked for one of the other ponies to get me. I sent some of the guards in to take you back to my castle where you’re being treated for your injuries,” Celestia explained.

“Injuries?” you asked.

“Yes, Jason. It appears that your groin and pelvis bones were fractured in several places and you also incurred some severe bruising as well. Luckily, we were able to mend your injuries without incident.”

“Damn, she really let me have it, then. Princess, do mares always go out of control like that when their estrus kicks in?” you asked.

“No, normally they keep their urges in check, but somehow, Berry’s behavior has become a bit of an issue along with all of the other mares. Which brings me to the subject I would like to speak to you after you woke up,” she said.

“Alright, I don’t know what’s going on, but I’m definitely curious of what this is about,” you said.

“Very well. You see, Jason, every mare in Equestria has gone into their estrus at the same time and this isn’t some normal occurrence. I’ve made a discovery of an evil succubus casting a spell on the mares, turning them into sex-driven zombies, minus the rotting flesh. You’ve already experienced what they’re capable of if they get their hands on other stallions. And I’m afraid I can’t allow other stallions to get hurt in the process, so I’d like to ask you of a huge favor.” the princess said.

“Go ahead and tell me,” you nodded.

“I need you… to help satisfy the urges of all the mares in Equestria.”

“Wh-Wh-WHAT?!” you asked, panicking.

“Now, now, before you lose your head, I will guarantee you will not end up like you are now. I can easily cast a spell to make your body and bones more durable. Another reason why I’m asking you is because unlike the others stallions, you DNA is much different from the ponies so there’s little to no chance of you getting any of the mares pregnant.”

“So, you’re charging me with satisfying the desires of mares driven mad by a sex demon? Why can’t you expel the demon from this mortal plane?”

“I require a portion of my power to move the sun every day. Because of that, I can’t seal the demon away. The best I can do is mitigate the damage to a certain extent. Even my sister, Twilight, and Cadence are unable to help as their magics are being affected by this entity.”

Contemplating for a moment, you thought about the situation at hand. Right off the bat, you only knew the existence of demons in the folklore, mythology, and movies from your homeland. It was almost impossible for you to believe, even when you’re living in a land of mythical creatures and magic. Yet, you’ve always known that when something is dire, Celestia never fudges the facts at all. She certainly meant truth in her tone.

“How would you want me to go about this, your highness?” You replied in agreement.

“Since you’re a doctor and you sometimes travel, you’ll be handling this situation on a case by case basis.” She said as she helped you up back up on your feet. “You can take on cases at your leisure. Until I can find a way to banish the demon without my magic, it’ll fall on you to keep things under control.”

“Hmmm, seems simple enough.” You dryly replied. “As long as none of my bones are broken over this, I’m fine with it.”

“I know Jason,” Celestia said, placing a hand on your head, glowing with the same intensity as her horn. “I know you are.”

Then, a pulse of crackling yellow energy started pulsing through your body. Your injuries seemed to be vanishing and you felt your stamina being replenished. And right after that, the yellow energy around you faded away.

“Celestia, did you--?”

“I’ve managed to heal you and casted a spell on your body. Now whenever you’re courting the mares, your body will feel less pain than it did before. You have our best wishes on completing this task.”

“Thanks, but I do have one more question.”

“Of course, what is it?”

“You said that Cadance, Twilight and Luna are unable to hold back the spell because it’s affected them, too. If it comes down to it, should I help them or is it too dangerous?”

“Though they are affected by this danger, the one thing they crave the most is carnal pleasure. Lust does the talking for them. If you give them what they want, they’ll be pacified. But, be prepared for anything. This is not a task to take lightly at all.”

“Understood, I’ll see to it that I don’t fail this task.” And so, you stretched your body before you headed for the door. “Well, wish me luck,”

“Good luck, Jason,” Celestia said. With her best wishes, you exited the hospital room and put on your best brave face for the challenge at hand.

“Alright ladies, Starting now, your estrus ends here. And once I’ve finished, I’m coming after you, evil succubus,” you said quietly, venturing forth. In your career as a doctor, never once did you think that you would be involved in the impossible. As your father once said, life has a funny way of throwing you a curveball. The only thing you could do was embrace your new charge, despite its difficulties. You’ll adapt and persevere. Still, part of you is bound to enjoy it.
