Chapter 1

It's been three days since Nerceli has been away; she told me before she left that she has business elsewhere for a while. Yesterday, she sent a letter saying that she'll meet me at the Apple's Pub's Pub, a joint to have a good drink over here in Manehattan. My name is Frank, a twenty-nine-year-old human that lives in Equestria. I have green eyes, blonde hair, a small mustache, and a scar on my shoulder from an accident I had when I lived back on Earth. However I got here, still remains a mystery to many ponies, including myself.

I met Nerceli when I was accepted into an Equestrian college here in Manehattan. We hit off well and in two months, we became a couple. I work over in a coffee shop, but for Nercelli, she never told me what she does for work. It's been a bother for a while and I still think about it at times. Besides work, she's a sweet mare during the day, but by night, she's different. How so? During the night, especially during a full moon, she's a freak in the sheets.

Each time we have sex, it's as though she's getting better to please me. Her voice makes my ears melt and her body is out of this world. Any stallion would love a mare like this one. After a year since we became a couple, we got an apartment together and have been living with each other since. The two of us would split the bills, but freakishly, she pays most of them. I don't know how she gets the bits, but she gets paid a lot of them.

It's been five years now and never have I expected to be living with a sweet and lovable mare as Nerceli.

After a long day of work, I walk along the sidewalk, wearing my casual wear of slacks and a red T-shirt. Today was busy than ever because one of the baristas happens to be sick and I took over his shift for the day.

"Ugh," I said, as I scratch the side of my head. "I feel worn out. I can't let Nerceli see me like this. Better go get a drink to refill my batteries."

There's a good place not too far from where I work called Apple Pub's Pub. Apple is a nice mare and a great bartender; Nerceli and I met her and once the three of us graduated college, she said to us that she's having her own pub. It didn't do well at first, but in a month, many ponies came in for a drink. Apple has a bright-yellow mane, light brown fur with a splash of white at her hooves, green eyes, and wears a necklace from her beloved grandmother, who taught her to be herself and make her dreams come true.

I walk into the pub, as I spot Apple looking at me across from her bar. I also got some looks from other stallions, but I just ignore them. I forgot to mention that there is a bit of bad crowd around here. One time, a stallion lost one of his fingers because he pissed off another stallion.

"Hey Frank," said Apple, as I take a seat on a stool. "What's up with you? You look exhausted."

"I took double shifts today because of one of the guys got sick," I said, rubbing my left temple. "I need a drink or a few."

"What'll it be?"

"Hot Mare, please."

"Coming right up," she said, as she bends down to get a glass. "Where's Nerceli? She at work?"

"She'll be here soon," I replied, as she stands up and pours down the liquor. "It's still a mystery to what she does for work. We've been together for five years and she still won't tell me what it is."

"That mare is a mystery to me, too," said Apple, as she places my drink in front of me.

"Thanks, Apple," I said, as I grab ahold of my drink and took a sip.

"No prob, Frank."

"Hey Apple," called out a stallion two stools to my left. "Another filler, please."

"So good to hear a polite stallion around here," chuckled Apple, as she walks over to the stallion with a smile.

I take another sip of my drink before looking back around the pub, seeing stallions with their marefriends, talking and enjoying themselves. My attention then goes to the door, seeing a very familiar mare walk in with her usual dark-purple shades and striped shirt with a long light-grey skirt. Her name is Photo Finish; I don't know much about her, but I do know that she's a photographer of fashion designs and she has done some interviews with many ponies from all over Equestria. Some stallions give out a few claps, while many mares surround her excitedly. For me, I don't care; I'm not a big fan when it comes to fashion. I pick up my drink and took another sip of it.

"Looks like the place is gonna get noisy for a bit," I thought to myself, as I place my drink down.

"Hey there, Miss Finish," said Apple, making me look to my left to see Photo Finish sitting beside me. "How's the business?"

"Everything is going smooth, I should say," replied Photo. "I vould love cider, please."

"Coming right up," said Apple, as she walks over to the end of the bar and pulls out a mug.

I look back at Photo, who looks over to me. I never sat close to someone (or in this case somepony) famous before.

"Uh... hi?" I said, trying to be friendly.

"Hello, human," she said with a friendly tone. "So good to meet you here. I've been looking for you actually."

"What?" I said with a cocked brow. "Really?"

"I was vondering, vould you like to haf your voice heard all over Equestria?"

"You mean like an interview?"

"Vith a few shots of yourself. You'll be paid handsomely."

"Wow... uh... would this interview be like... about myself and what it's like back on Earth before I somehow got here?"

"Yes. Don't vorry, you can keep personal things to yourself."

"Wow... I never imagined getting an interview by a famous mare and have my story heard all around Equestria," I thought. "Perhaps if this happens, ponies could start treating me differently or something interesting could happen."

"Vhat is your answer? I can give you time to think about this."

"I'll do it," I answered. "My marefriend would love to read it. She's quite a fan of your works."

"You haf a marefriend?" she said with surprise. "Vhat ist her name?"

"Her name is Nerceli. We feel in love five years back when she and I were in college."

"How sweet," she said, as Apple comes back with a full mug of cider.

"What are you two talking about?" asked Apple, as she rests her head on her hands.

"I'd like to interview vith him," replied Photo. "He has agreed vith me."

"You serious?!" said Apple, as she looks towards me astonished. "Are you sure about that, Frank?"

"I wouldn't mind ponies, Minotaurs, or whatever to know about me," I replied. "It makes me feel noticed. I bet not everypony knows of my existence."

"Well, that does make sense, but what about the paparazzi?"

"I wouldn't mind signing autographs and having more ponies interview me. I'd feel as famous as Keanu Reeves."

"Who's Keanu Reeves?" asked both Apple and Photo.

"A famous actor back on Earth," I answered. "He's done a lot of cool movies. The latest film to my knowledge before I got here is a film called John Wick. Kickass film with a lot of fast-paced action."

"Oh, cool," said Apple, as she takes her elbows off the bar. "Well, if you're okay with that, then so am I."

"What are you? My mother?"

"Oh, shut up," she chuckled, as she walks away to give a stallion his refill.

"So how's your day?" asked Photo, as she takes a sip of her cider.

"My day has been doing good," I replied. "My marefriend is meeting me here anytime soon. She's been out on business."

"Vhat does she do for vork?"

"I'm not sure. She never tells me what her job is."

"How Vierd. She should tell you. Perhaps maybe you're not ready yet."

"Huh?" I said, coking my brow.

"Maybe she'll tell you vhen you're ready. Trust me. Perhaps ask her tonight."

"Why tonight?"

"Nighttime seems like an appropriate timing."

"Mares are strange," I thought, as I took a sip of my drink.

"Oh!" said Photo, as she sticks her hand into her skirt pocket and pulls out a card. "Here. Vhenever you'd like to call me for zat interview, I'm all ears."

"Thank you, Photo," I said, as I take her card.

"Vhat time is it?"

"It's four-fifteen," I said, pointing to the clock over to my left at the wall across the bar.

"Oh, sveet Celestia!" she shouts, as she grabs her mug and gulps down a few sips before slamming it down onto the bar. "I haf to go."

"I'll let you know when I'm ready," I said, as she places five bits onto the counter and rushes out of the pub.

I smile, looking back to my drink and taking another sip.

"What was up with her?" asked Apple, as she comes back to me. "Did you scare her off?"

"No. She said she has some business to attend."

"I see," she said with an agreeable nod.

An hour has passed and still no sight of Nerceli. I want to call her, but she might be talking with her boss, so that's a no-go. Outside, Celestia's sun slowly goes down, making outside look orange and a bit dark by the shadows of buildings. I look back to the bar to see Apple coming up to me, setting down my third glass.

"Isn't she coming?" asked Apple, as she places my glass in front of me. "Did you call or text her?"

"I'm afraid she's talking with her boss and that I should not call or text her if that's happening."

"Good point," she said with a nod. "Just don't drink too much, okay?"

"You know I only have three drinks. That's my limit."

"Just looking out for you."

"You don't need to worry about me, Apple. It's not like I'm gonna drink as much as I can until she makes it here."

"I care about you like a family member."

"You'll be a great mom one day, Apple. You'll get married, have family of your own, and perhaps your child or children can take over your bar for another generation."

"I don't know about my children taking over this bar. They have minds of their own your know. If they don't want to take over this bar after me, then so be it."

"But this bar has been in your family for many years. At least have one of your kids take over. This place if like your family's legacy."

"... I'll think about it."

"Don't let this place go down."

"By the way," she said, smiling towards the entrance. "Somepony has finally made it."

I turn around to see none other than Nerceli, wearing black pants, and a dark leather jacket. Her dark purple tail sways back and forth as her cyan-colored eyes gleam and a smile appears on her lips. She runs up to me and hugs me tight, making me almost spill my drink. She gives me many kisses, as her breasts squish against my chest.

"How have you been, Franky?" she said in a cheerful voice.

"I'm a bit tired," I replied. "But luckily I've been recharging my batteries with a few drinks."

"I might as well join you three," she said, as Apple stretches out to hug Nerceli. "Good to be back, Apple."

"What would you have?" asked Apple, as Nerceli sits on the stool on my left.

"I'll take a small glass of Wild Berry."

"Coming up," she said, as she reaches down and prepares Nerceli's drink.

"Also, Nerceli," I said with a smile. "I met a certain famous mare today."

"What?!" she said with a gasp. "You met Photo Finish?!"

"How is it that at times you know before I say it?"

"What did she ask or say to you?" she said, ignoring my question.

"She gave me this," I said, as I pull out a card from my pocket.

Nerceli's horn glows, making the card slip out of my hand and looks down on it with a big smile on her face.

"Franky, you made my day," she said, as her tail swishes back and forth rapidly.

"She wants to do an interview with me and tell my story to Equestria."

"Make it happen, Franky!" she begs. "Please do it for me."

"I'll let her know when I'm ready. That card is important, so don't lose it."

"I'll guard it with my life," she said, as Apple places down her red colored drink.

"Looks like somepony is happy," said Apple.

"My lover is gonna get interviewed with Photo Finish," she squealed. "I'm so excited!"

"Calm your tits, Nerci. You're acting like an excited filly."

"I can't help it, Apple. This is a once in a lifetime chance. He has to do it."

As the two friends talked, I think back to Photo, telling me that perhaps tonight, I should ask Nerceli about her job. Nerceli has to tell me eventually; she can't hide it forever.

"Time I figured out what your job is tonight," I thought, as I take two sips of my drink.

Chapter 2

It's six PM, as Nerceli and I make it to our apartment. As I unlock the door, Nerceli walks past me and into the living room, where she gives out a stretch before slumping backwards onto the couch. Now is a perfect time to ask Nerceli about what her job is; she can't hide it from me forever.

"Phew," she said, as I lock the door. "What a day."

"I'm a bit tired, but Nerceli," I said, as I stand up straightly and walk up to her. "I need to ask you something."

"What is it, babe?"

"Nerceli, I'd like to know what you do as a job," I said bluntly. "Why won't you tell me?"

"Frank," she said, cocking a brow. "Why are you asking me now?"

"Just tell me, please! I need to know! If you're doing something shady, then I need to know."

She gives out a sigh and scratches the back of her head.

"Okay, okay," she said, as she stands up.

She walks up to me and grabs my hand.

"Come," she said calmly. "Let's do this in the bedroom."

"W-why in the bedroom?" I asked, as she pulls me down the hall towards the door at the end.

"Because I prefer to show you in there than in the living room," she said, as we reach to the door.

She twists the knob and pushes the door, bringing us into our bedroom. Our room isn't too large, but I'd say it's an average sized room. Even though the room is dark, the walls are light-blue, and our bed has red covers with matching pillow cases. Beside the bed to the left is a lamp and on the right to where we'd entered, there's a dresser full of our clothes.

As we got close to the bed, she pushes me onto the bed, before walking to the lamp and turning it on, making the room somewhat dimly lit. She then walks back and stands in front of me at the end of the bed.

"Frank," she said, as she pulls down the zipper of her leather jacket. "What you're about to hear will make you think about me differently."

As the zipper makes its way apart, she takes it off and tosses it aside. Beside the shirt, I noticed dried blood on her left arm, as though she got it from a knife fight. Is she some sort of killer?!

"Oh God," I thought, as my heart races. "Don't tell me my marefriend is a psycho!"

"You see, Frank," she said, placing a hand on the cut. "I'm not a normal mare. I'm not a psycho."

"You're scaring me, Nerceli," I said. "Why do you have that cut."

"Well... you see... I'm a bounty hunter."

"A bounty hunter? You kill ponies for a living?!"

"N-no!" she said, shaking her head. "I don't kill ponies."

"Then... what do you kill?"

"I... kill demons."

"Demons?!" I shouted. "Creatures with horns and shit?!"

"Yes... those things."

"Babe, I knew you were awesome... but not this awesome!"

"Y-you don't mind?" she asked, cocking a brow.

"Babe, I knew I chose the right mare."

"Not just an ordinary mare."

"Huh? What do mean by 'not just anordinary mare'?"

"That's something I'm going to show you now," she said, as she sticks out her hands out to her sides. "What you're about to see will shock you."

"Wh-what do you mean?"

She closes her eyes and before I knew it, two large black wings sprout from her back, giving out a few flaps. My eyes widen, as I gaze upon those large black wings. Her ears began to go pointy like that of a bat and her nails grow long and sharp. She breathes in and then exhales before opening her eyes, showing her slit pupils. My heart skips a beat, making want to fear her, but yet... I shouldn't. She looks at me, then turns her head with her wings covering her face.

"Do you... love me now?" she said with a hint of sadness. "Do you think of me as a monster?"

She sniffles, as I get up from the bed and grabbed ahold of her wings, pushing them aside to see tears flowing down her face.

"Nerceli," I said, before stretching my hands and wrapping them around her. "You may be this... thing, but I still love you."

"Y-you're just saying that," she said, thinking that I'm lying.

"I'm not," I said truthfully. "I'd love you even if you were this thing. I can still see the mare I fell in love with five years ago."

"F-Frank,"she said, as she looks at me in the eye. "I'm so glad I ever got together with a human like you. You... You're my everything."

"I love you, Nerceli."

"I love you, too."

She folds her wings, as I place my hands on her cheeks and using my thumbs to wipe off the tears. She smiles at me with her lovely slit-pupil eyes, telling me that she'd love a kiss. I bring my face closer to hers, as our lips touch, letting all the passion into one another. As we kiss, I open my eyes to see Nerceli's wings stretch out and push me closer to her, as they come to my back. She then decides to change things, as her tongue slips into my mouth, rubbing it against my tongue. I follow along, as our tongues fought for dominance. Somehow, her tongue feels different, but I don't care.

She breaks the kiss, as her tongue pulls out with a pop. My eyes lit up, knowing now that her tongue is much larger than before. Her tongue is about three inches long and looking like that of a snakes. She pulls her tongue back in her mouth, smiling with sharp teeth that gleam from the lamplight.

"Damn, Nerceli," I said. "That's some tongue you have there."

"You'd be amazed what this tongue could do," she said with a giggle. "I'll give you a taste of what it can do, unlike my normal mare tongue."

She folds up her wings before placing her hands onto my chest and giving me a light push onto the bed. As I lie on the bed, she reaches below her shirt and pulls it up, showing off her black bra. After tossing her shirt aside, she reaches behind herself as her bra comes off with a click. Her bra falls, showing off her soft and lovely breasts that I always love. She then crawls onto her fours with her tail swishing back and forth in a playful manner. She stands above my legs and takes a hand to rub my covered and not-so-hard member. As her hands rub between my legs gently, I began to feel my erection coming on, slowly forming a bulge in my pants.

"Looks like someone is ready for some action," she said with a toothy grin. "Let's let him free."

She unbuttons my pants, uses her magic to pull down the zipper, and then pulls both my pants and boxers aside. My member comes straight up, twitching with anticipation.

"Let's get started, shall we?" she said with a lick of her lips.

She sandwiches her breasts around my rod and squeezes them, making me give out a moan. Her breasts are so soft; it's like having my member between two rubbing marshmallows. As she moves her breasts up and down at a quick rate, she looks at me with glowing eyes with a lick of her sharp teeth, which I somehow find quite erotic.

"Give me your delicious sperm, Frank," she said in a sexy voice that clouds my mind. "I want to taste it."

"Y-yes, N-Nerceli," I said, as my member gives out a tingle.

"I can feel your cock twitching a bit," she said, as she stops moving her breasts. "Are you feeling your balls getting ready to explode onto my tits."

"Y-you're voice is... so erotic," I said, as I thrust upward, making her gasp.

"Oh? Eager to release? Don't worry, I'll help you with that."

She opens her mouth and wraps her lips around the head, making me give out a gasp. Her tongue licks around the head, swirling around as though she were licking a popsicle or lollipop. She then proceeds to bob her head up and down quickly, as I give out a grunt. Never before has sex felt this good; with Nerceli's new form, my body feels more pleasure than ever. I then began to feel it; the build up of cum read to burst forth. I lean up, grabbed her head, and thrust within her mouth as hard as I could. Her muffles fill the room, along with a few gargles as my member reaches to the back of her throat.

"Here... I... c-come," I said, before making one more thrust into her mouth.

My sperm bursts forth and slides down her throat, as she gives in a few gulps. I then pull out my member from her mouth and away from those breasts of hers, as I lay back and give out a few heavy breaths. She gets off the bed and stands at the end, licking her lips.

"You came much quicker than usual," she said. "Is this form of mine work a lot better than when I was a mare?"

"Y-yeah," I said, surprised that she somehow knew that. "How did you know?"

"Franky," she said with a giggle. "I have the ability to read minds."

"What?!" I shouted. "You can read my mind?! That's playing dirty!"

"I love reading your mind," she said, as her tail swishes back and forth. "It was cute when we started dating. You were so nervous that you thought about throwing up if things got out of control."

"I was nervous! A lot of guys get nervous when they start dating! Jeez, Nerceli."

"You're quite cute when you're nervous, Frank," she said, as she slips her fingers to the sides of her pants. "I'm getting wet from just how cute you are now."

She slowly pulls down both her pants and panties, showing her love juices flowing down a little on her left leg. As they reach to the bottom, she kicks them aside before crawling towards me. She places her hands on my chest before having her lower lips rub against my still rock-hard member. The two of us give out moans of pleasure, while her love juices slide down my member and down my sides.

"Your cock must have at least some energy left for another shoot, right?" asked Nerceli.

"Do what you like, my sexy demoness," I said, making her giggle.

"You're such a sweetie," she said before bringing her lower lips above the head.

She slowly goes down my shaft, making the two of us moan loader than before. My body tingled with pleasure, along with Nerceli's body giving out a shudder.

"Oh, s-sweet Celestia," purred Nerceli. "Your cock feels so good."

"You feel very warm than usual," I said, as my member within her felt a wet, yet warm feeling.

"D-demon bodies always feel warm when there's sex involved."

"Why not when we had sex when you were a mare?"

"Just shut up and let's fuck," she said, she jumps up and slams down hard onto my member, making me gasp.

"Not... too... hard," I said, feeling a sharp pain on my waist.

"Sorry Frank," she said, patting my chest. "Just let me fuck your cock."

She jumps up and down my member, only this time, not too hard. As she jumps, her breasts bounce along with her, making me reach my hands out and grabbing them by the nipples.

"Oh, y-yeah," she said, as she continues bouncing. "Pinch my nipples! Make me cum from both my pussy and nipples!"

As her body continues to move, my member begins to get use to her warm insides. Never have I had sex with a demon, and yet, this demon just so happens to be my marefriend. Even if Nerceli is a hunter and a demon, I'd still love her from the bottom of my heart. Besides, demons are quite the trend back on Earth. I still remember my friends telling me to get a novel called Succubus Summoning 101, which I did get, but only got to chapter three before getting myself here somehow.

The room becomes filled with the sounds of sex, as Nerceli continues going down on my member that began to twitch within her.

"F-Frank," she said, as she looks down at me. "I'm about to c-cum!"

"M-me too," she said, as the two of us thrust against one another.

As we continue to try making each other climax, I felt warm liquid coming down from my hands, chest, and arms. Her nipples are producing warm, yet black ooze. It looks rather gross, but I'm guessing this is what demon milk looks like.

"Wh-what's with your milk, N-Nerceli," I asked.

"Don't w-worry," she said, as the two of us continue our thrusting. "It's demon mil-ah!"

After her gasp, I to gave out a gasp as our love fluids mixed together and flowing down my waist. Her black milk too began jetting out like a small hose, spraying onto my face for about three seconds, until her nipples dribbled down onto my black-milk covered chest. She pulls herself off my member and lands onto me with her breasts squeezing against my chest. She breathes heavily, as I lick the corner of my mouth, wondering what the taste of demon milk tastes like. Surprisingly, it tastes like ordinary milk; perhaps there might be a kick to it.

"Nerceli," I said, as she looks up to me with her slit pupil eyes.

"Hm?"

"Is this demon milk good to drink or is there something that I should know about it?"

"It's fine, Franky," she said, before sticking out her tongue and licking my right cheek. She gives it a taste and swallows. "Demon milk is harmless. It's actually quite good for you. It has vitamin C in it."

"Really?" I said with surprise. "I learned that pussy juice has carbohydrates or something like that."

"I'm well aware of that, hun," she said with a giggle. "Tell you what, in the morning, I'll make you a batch of pancakes."

"With cherry toppings?"

"Yes, with cherry toppings."

"You're the best, Nerceli," I said, giving her a kiss on the cheek.

"Before we go to bed, go clean your face and clean your chest. You look like a pen exploded on your face."

"Anything for you, my sexy demon mare."
