Length: 3983

Sunset writes in her spare time, and posts her own stories online. So does her girlfriend. And so does Fluttershy, apparently. Sunset would have assumed she was the only one of the three who was posting porn.

Sunset spends her spare time writing stories, which she then posts to her own profile on a website designed for people to publish their original fiction. She writes porn. Twilight has her own profile on the site too. She doesn't write porn, but she does enjoy the one Sunset writes.

Fluttershy, it seems, also has a profile on the site where she posts her stories. Sunset was not expecting it to be porn. She definitely wasn't expecting it to be that kind of porn.

This story takes place after About That. Knowledge of the events of that story and other previous installments in this AU is not required to understand this one, but still recommended, as reading them will give a better understanding of this version of the characters and world.

"So you write there too?"

Sunset stepped through the doors to the library, one set of fingers nervously drumming over the laptop held in her arm while the other clutched the strap of her handbag just a little too tight. Twilight was busy repairing her brother's arms, and that meant they wouldn't be able to meet until later, just before dinner at best. The natural solution was of course to log into her account and write some porn while she waited.

Walking up to the nearest empty table, she tried to think about what she could work on. She did have an unfinished incest scene between a mother and her daughter, but that could wait, she wasn't particularly inspired by the concept right then. Perhaps a sequel to that old hypnosis BDSM piece she'd put out once, or maybe something entirely new, maybe something different from the norm, maybe-

"Hello there, Sunset."

The girl in question stopped and turned around. "Oh, hey Fluttershy. Didn't see you there." She took a couple more steps and sat down on the plain empty chair besides the other, setting her bag on the ground. "So what brings you here?" she asked, placing her laptop on the table and turning it on. "Studying?"

"Yeah, studying." Fluttershy threw a look at her tablet. "And you?"

"Yeah, me too."

The two stared at each other for a moment, then both cracked and began to giggle.

"No, seriously, what are you doing here?" asked Sunset, as she turned her monitor slightly to the side and logged in to her account.

"That's none of your business, Sunset." Fluttershy returned to typing away on her device, leaning back into the padding of her seat.

"Oh, do you want me to force you?" The red-haired girl threw a mischievous glance at her friend.

The other gave a small, peaceful sigh. "That was years ago, Sunset. And it lasted just a couple of months."

"Yeah, but you liked it. Wouldn't you want to go back to that?" As she said so, one of Sunset's hands snaked its way to Fluttershy's arm.

"I wouldn't want to go back to that, Sunset. And I'm not interested in the proper version of it we could have now. But even if I was, what would Twilight think of it?" Fluttershy stared right at Sunset as she asked that.

"That it's hot as fuck, probably."

"Is that what she would think or what you want her to think?" The girl set her tablet down and adjusted a strand of her pink hair, bringing it away from her eyes. "Listen, Sunset. It's alright. I get that you're sorry for what you did then, but like I've told you already, it's okay. It's in the past. Move on from me."

Sunset opened her mouth to speak, then just sighed and shook her head. "You're right. I'm not like this, usually." Resting an arm vertically on the table and her chin on top of her fist, she stared in the distance with a sigh. "I was supposed to meet with Twilight earlier but she had to help Shining, so I've been kind of on the edge this afternoon, and then you came in and I just... Sorry. I did what I usually do with her, and it reminded me of us."

Fluttershy just gave her a warm smile.

Sunset returned the expression. Then, with a half-covered grin and a sweep of her hand, she snatched the other's still-glowing tablet away from the table. "Moving on to a different topic, what do we have here?" Her eyes scanned the screen, while a kick of her leg sent Fluttershy's wheeled office chair towards the shelves. "Oh, you're on this site too? That's a coincidence. What is your..." Sunset's words stopped, and she almost dropped the tablet.

Having finally stepped up from her chair and walked back to the table, after the small moment of shock that had allowed Sunset to push her away, Fluttershy grabbed her tablet back in her hands. She stared down at Sunset's petrified expression for a moment, then asked, "Do you, ah... Have you read any of my stories?"

The other slowly looked up at her. "I-" she began before immediately cutting herself off. "Can we go somewhere more private?" she asked, grabbing her bag.

"The music lab should be free right now."

Both girls fetched their electronics and walked out of the room, down the corridor and through the door on the right at the end of it.

Sunset locked the door behind herself, and let her eyes wander inside the sound-proofed room for a moment, making sure no one was there beside them. "I fucking love your stories! Are you seriously the one behind all that?"

Fluttershy nodded, pursing her lips.

"Fuck!" Sunset began to pace around the room. "I-I'm not sure what to say. Is this what Twilight felt when she found out which account was mine?"

"You have an account too?" There was a sudden note of curiosity in Fluttershy's voice.

Sunset stopped walking, realising she'd let slip out more than she'd planned. "Well, uh, yeah... B-But my stuff is not as good as yours, it's kind of- Well, people seem to like it, but I'm never sure. I like it, but I'm always a bit anxious. And I have nowhere near the courage to write some of the stuff you put out."

The last comment made the girl blush and look to the side for a moment, then she focused on her friend again. "So what's your username?"

"I, uh... It's StraightThroughTheMirror, not sure if you've heard of it, almost at a thousand followers now." Sunset gave an awkward laugh, rubbing the back of her head. "Dumb pun, yeah, I know, I like the song and thought it was funny, though it really doesn't mean anything if you don't know it's me and-" She cut herself short, and flashed a smile, then nervously sighed.

Fluttershy began to type on her screen. "Oh, yeah! The one who put out that student and teacher spanking story last month. I've actually read your stuff, it's pretty good."

Sunset's expression dropped. "Really?" She began to skip from leg to leg, holding her fists to her chest and looking up at the sky. "Oh my gosh oh my gosh ohmygosh. Chainwrapped just said she likes my stuff! Ah! This is the happiest day of my porn-writer life!"

Fluttershy gave a short laugh, bringing a hand to her mouth. "You mentioned Twilight, does she have an account too?"

Sunset's dance of happiness petered out. "She does, actually, but I'd have to ask her if she wants to share which one it is with you. She doesn't write porn though." She stopped for a moment. "Well, unless she has an alt she hasn't told me about. She might do that just for what will happen once I do find it."

"Still swinging that paddle, uh?"

"Oh, that's just the start of what I'd do to her." Sunset looked towards the distance for a moment, her mind already working on what her and her partner would get up to later that night. "Anyway," she resumed, shaking herself out. "Should I tell her about your account?"

"I'd rather you didn't." Fluttershy leaned back against a desk, moving a leg back and forth as she stood on tiptoes. "It's not exactly something I want to parade around, you know."

"Won't be the first secret about you I'm keeping."

"Yep," Fluttershy agreed, looking to the ground.

Sunset placed her back on the door frame. "Do you still have that piercing?"

"I do. I had it coloured black, actually."

There was a moment of silence.

"Can I see it?"

Fluttershy looked up, raising an eyebrow. "Seriously?"

"It wouldn't be the first time, no?" Sunset continued.

The other girl shook her head, staring at her ex. "Sunset, please. You're not decent when you're horny. Just because we were fucking at one point doesn't mean you can ask me to undress whenever."

"Sure, talk about decency. You didn't care for it when you wrote about that girl getting throatfucked by an alien's horsecock while he injected drugs in her brain, did you?" Sunset looked distant for a moment. "Wow. I still need to process how you wrote all that."

Fluttershy looked to the ground. There was a blush on her cheeks, but also a hint of pride in her expression. "Do you want to see what I'm working on next?"

Sunset stared blankly at her for a second. "I-I-You-I-Wha- Yes! I mean, yes, I would like that, yes." She stepped towards her, trying to force back the mounting instinct to hyperventilate.

Fluttershy's fingers danced on her screen a little more, and she scooted to the side to allow Sunset to lean on the desk beside her. "Here," she said, turning the screen slightly to allow the girl on her side to see what was on it. "This is the rough outline and the first few paragraphs."

Sunset quickly read over the sketch. "Oh my. How did you even get the idea for this?"

Fluttershy smiled. "It's funny, actually. Rainbow and I had a cheap horror movie night at Pinkie's place to cheer her up. We watched a werewolf movie first and one with aliens afterwards, and I just kind of combined ideas from there."

"Still, the forced gender change is all yours, I think." Sunset read and reread the first few paragraphs over again, trying to pick them apart in hopes of extracting some secret formula for quality.

Fluttershy nodded. "It is. I thought it would be a fun subversion of typical virus spread tropes, and also play nicely with the werewolf aesthetic." She looked to the side. "Also, I can write an only female harem cast but still have gang bang scenes and heavy maledom, so that's nice."

"And impossibly sized dicks, and borderline bestiality. You seem to like those more than a bit."

Fluttershy didn't answer, but simply moved a strand of hair from her face to behind one of her ears, while a subtle smile danced on her lips.

Sunset looked back to the screen. "And it ends with them all getting turned, uh? That's dark. Not that the rape and physical overpowering isn't, I guess. This is weird stuff. Though, I mean, I'm sure I'll enjoy it once you've worked your wordwizardry."

"It's not any weirder than the time I had a goo girl seep into a normal one."

"You're right, that did happen." Sunset bit her lower lip. "And I did like it."

"It's not like your stuff isn't dark at times, you know?" Fluttershy set a hand on Sunset's shoulder.

"Hey now. Hypnosis falls under dubcon, you know that."

"Only if you don't have the guts to call it for what it is. But then, you'd be writing some real fun stuff if you had those anyway." Fluttershy set her tablet down and stared in the other's eyes.

"I'm not c-comfortable writing some stuff, o-okay?" Sunset drew back slightly, suddenly concerned about the way Fluttershy was leaning over her.

"You seem pretty comfortable masturbating to it. Maybe you should admit you're just scared of not being good at it, because it's clear that you want to write something like that." She was completely in front of Sunset now. Her fingers rested over the other girl's, and as Sunset leaned back against the desk Fluttershy stood on her tiptoes, staring down at her.

"F-Fluttershy?" Sunset realised just then how her hands were caught between the desk and the other's palms, and how her friend's body was starting to press against hers.

Their faces were just a few centimetres apart, their breaths touching each other's skin, then Fluttershy pulled back with a guilty, amused giggle and turned around. "That's the other reason I don't want to get back with you, Sunset. You were never comfortable being on the other side of the leash." She let out a sigh and sat on top of the nearest table, fetching her tablet back up. "Anyway, I have an offer for you."

Sunset was focused on rubbing the backs of her hands, but she perked up at those words. "What is it?" she asked, unconsciously leaning away from the other girl.

Fluttershy answered without looking up from her screen. "Well, you clearly want to push the boundaries of what you're comfortable writing, for one. I, on the other hand, was thinking I might need a bit of assistance with something on this story. I thought we could help each other." She finally looked back at Sunset. "You know, I really like the way you handle physical interactions between characters. It's something that comes from experience."

"I- Thank you and-" Her eyes shot wide. "Wait, you're asking me to collaborate with you? Help you write this story?"

"And you get to put your name on it alongside mine. Second though. And a little smaller." Fluttershy flashed her a smile. "I was under the impression you would enjoy that. Was I wrong?"

Sunset stuttered for a good number of seconds, seemingly stuck in a loop of repeating I's. Finally, she shook herself out of it with a small yell and a pull on her own hair. "Yes!" she managed to reply before hyperventilation took her again.

"Thank you." Fluttershy stepped towards the desk again. "It's specifically the first post-transformation scene I need help with, the one from the infected girl's point of view. I don't have experience wearing a strap-on and I think it should be something similar to that."

Through sheer force of will, Sunset calmed herself down. "Well, okay, let me think. It's not exactly the same, you don't get physical sensation in the shaft when you wear one, but I suppose it might be a bit similar. I can definitely help you with the whole thrusting thing and what that's like."

Fluttershy looked to the side for a moment, biting on her upper lip. "There's also, well... The whole transformation business. Being in a body that's alien to you. Do you think you might help getting that across right too?"

"I..." Sunset paused for a moment. "You know, I'd never thought about writing something like that. I guess I should be able to pull off some decent transformation stuff given my experience. I think I can help there, yeah."

The other girl smiled. "That's nice of you. I guess it will be a bit of the reverse of what you went through, gaining fur instead of losing it and all that. We do need to figure out how to properly write about the dick growth though."

Sunset began to tap her chin, already working on ideas in the back of her head. On the front was something else though. "Are we making them impossibly large as usual?" she asked with a smirk.

Fluttershy blushed. "Well maybe I wouldn't have such a thing for size if you hadn't been taunting me with that thing you kept on the shelf."

It was the other's turn to blush, as she gave an awkward giggle. "I've never actually used that. Not on me, and not on Twilight either. She's not really into the idea."

"Oh, now you care about the other's limits, huh?"

"Because you totally aren't into non-con, right?"

The two stared at each other, then finally broke into a laugh.

"Okay, so how do we do the first scene?" asked Sunset, opening her laptop back up and navigating to a new document. "How much of the transformation sequence should be sexual and how much horror?"

"I was thinking all of it for both." Fluttershy checked the few paragraphs she'd written to make sure she was starting back from the right spot. "You know that one story I wrote where the protagonist goes through a full body orgasm while being melted by the spiders' venom? Sort of like that."

Sunset bit her lower lip. "Wouldn't this be closer to the one where you wrote about that girl fusing with the fabric of her clothes, since it's not as destructive in nature?"

"Not really. The focus was mostly on breast expansion and mind alterations there. Here the mental part should be more of a struggle against instinct. Compare it to the one you wrote about two witches fighting, it should be closer to that than to your other hypnosis stuff."

"That was a fun one." Sunset stared in the distance for a moment. "I did especially like the twist. And the breastplay leading up to it. And all the cunt rubbing before that too. Although my favourite scene was probably the petplay oral at the end, and thinking about it I need to get Twi a tail plug." Noticing the silence, she looked at Fluttershy and saw the smile on her face, then blushed and stared back to her screen. "Anyway." She cleared her throat. "What about the anal scene? Do we go for painal or-"

"The usual nanomachines pheromones bullshit. We have them undergo full body transformation, the stretchiness will be justified." The girl seemed to perk up, and wrote something down. "Definitely adding in some hentai quotes to it too."

"Traditional 'how does it feel so good, it should hurt' stuff, right?"

Fluttershy nodded.

Sunset took some notes. "And about the facial, should we have just the tip go in or-"

"Throatfucking. All the way to the base, knot and all, with balls slapping against the girl's nose and eyes. A visible bulge in the neck."

Sunset's mouth opened a few half-seconds before the words actually came. "Wouldn't that be weird, with how big it-"

"Lots of cum on her face afterwards. Dripping from the nose and covering her whole face. But make sure you don't mention the hair in that part." Fluttershy tapped on her chin for a moment. "We'll have the beast choke her neck while it cums to justify the semen flowing back. And the alien robot-drugs keep her awake through it all despite the lack of air."

The other's mouth remained open a little longer. Finally, she shrugged and went back to taking notes. "So I was thinking we should underline the physical contact by having her press against the alien werewolf's abs. We need to plan it right though, so the cock doesn't get in the way."

"Oh! How about some pulling when there's two of them spitroasting one girl? Wrapping their hands around her limbs and such?"

"That's tricky to get across right. Hold on, let me fetch some bondage references so we can make sure it doesn't read like her ligaments should pop." Sunset opened a new window and began to type away.

"And then we have the alien broodmother gang-raped by the rest of the werewolves while the alpha self-bondages with the ship's interface and begins to spread the virus to the world, ending it there." Fluttershy finished tapping on her screen.

"Sounds good." Sunset took the last set of notes, then closed her laptop and stood up, placing it back in her bag. "I'll work on that physical overpowering scene tomorrow. I need to really get the feeling of her being pressed below all that hot furred muscled weight down. Oh, and I'll also start sketching out that tentacle nightclub idea we came up with, I really like your thinking with the music-synced vibrators and the whole new drug being a cover for hypnosis thing," she added, turning back as she walked to the door. Then she unlocked it, still thinking about how to properly integrate the spinal insertions during the anal penetration scene, and opened it, only to come face to face with a rather disgruntled Octavia.

"Having fun in there, Sunset?" the girl asked, clutching the strap over her shoulder a little tighter. She glanced past the other's hair to spot Fluttershy's meekly advancing frame. "Does Twilight know about this? Anyway, this is the music lab, it's for people to play music in." She pointed at the bag on her back. "Not for whatever you two were doing in there."

"What about the stuff you and Vinyl do here then?" Sunset crossed her arms with a smug expression, while Fluttershy reached her side, getting a bit more red with each second.

Octavia's frown didn't go away, but she did point it to the side rather than at the girls. She at least seemed to drop her argument. "You have it easy with Twilight, she transferred here," she muttered.

"The lab is just another study room, just one that happens to be soundproofed. Whoever gets in first keeps it, Principal Celestia added a lock for a reason. And a set of tissues and cleaning equipment. You're not the only couple who used it." Stepping forward, she pressed a friendly hand over Octavia's shoulder. "How's it going between you two, by the way?"

"Well enough." The girl sighed and seemed to relax. "She'll be playing at the fair this weekend actually, she might bring the rest of the Shadowbolts along."

"Uh, maybe we'll get to see Derpy again," Fluttershy cut in.

"Who knows," Sunset replied. "I do kind of miss her face around since she transferred there."

"Well, if you'll excuse me now I have my practise to get to." Octavia stepped between the two girls and through the door, then closed it behind herself and locked it.

"Do you think she's really practising or..."

"I give it about a forty percent chance she just wants a private reading space. You don't stuff a book that big inside your instrument's case unless you don't want people to see what it is," Sunset replied. "She probably didn't wait much anyway if she was still here, and if she didn't just go home then that must come from the library."

Fluttershy looked at her tablet one more time. "Seems like it's time to go for me. See you around, Sunset."

"See you." Sunset waved at the girl as she walked in the opposite direction. In less than minutes she was stepping out the front door of Canterlot High, and spotting a familiar set of glasses-covered eyes as they advanced towards the building. "Twilight!" she greeted her girlfriend, trotting towards her with open arms.

Twilight quickly ran up to her and completed the hug. "I'm sorry I had to spend the day away, Mistress," she whispered in the other's ear. "I'm all yours for tonight though."

"It's alright." Sunset lovingly stroked a hand through Twilight's hair. As they began to follow the sidewalk hand in hand, she feigned a cough to draw the other's attention. "Hey, you know that site we both write on? Have you ever read any story there by a user named Chainwrapped?"

Twilight thought for a moment. "Oh! I have, actually. I really like the one story of theirs where the giant praying mantis dp's the anthro dolphin. And that dystopia one where people are left hanging naked in public so they can be used by the robot overlords that have taken over the world, when they aren't being used as pets and walked around. Why do you ask?"

"Oh, no reason in particular, I like their stuff too." As Sunset looked to the side to make her attempt at deceit less obvious, her phone buzzed in her pocket. She brought it to her face to check. "It's from Fluttershy," she said, anticipating Twilight's question.

"What does she say?"

Sunset finally opened the message, and her eyes remained locked on the screen for a moment, as her mouth silently chewed. "Uh. She did have it coloured black after all," she said to herself.

"What?"

"Nothing!" Sunset locked her phone's screen with a jerk.

Twilight pursed her lips for a moment. "If you say so, Mistress. So what did you do today?"

Sunset returned to a normal walking pace. "Writing, actually."

"Oh really? On what?"

"You'll see, Twilight. You'll see."
