Let's face it, we all know you wanted an Equestria Girls incest fic with Pipp and Zipp.

Pipp has been feeling even more stressed out than usual since the Fall Formal. Luckily, Zipp is always willing to help, especially when it means she'll get to have sex with her sister.

Very important notice: In order to ensure that they are both of age, I have written these two as fraternal twins for this fic. I am aware that they aren't the same age in the G5 movie.

Contains: F/F, incest, cunnilingus, rough facefucking, vaginal and the worst ending you could possibly imagine (seriously, look at the end of the last chapter before you read this pile of shit).

Conceived, written, edited and pre-read (read "fapped to") by Arkadios, with feedback from various members of the Adult Writers Discord server.

Honestly, I'm kind of embarrassed that I thought this would make the feature box.

"You usually get to cum first when we do this." Zipp opened her backpack and, to Pipp's shock, pulled out her favorite toy: a strap-on with a well-endowed white attachment. "So here's your chance to change things up, if you want."

Pipp took a moment to process what Zipp was saying and all but pounced at the opportunity. She got off the stool, her shirt falling back down over her torso as she came forward and took the toy from her sister.

Zipp moved her hands to her waist to start shimmying out of her panties, but Pipp held up a finger. "Ah-ah, not quite yet, Zipp," she said. "There's one thing we need to do first."

"And what might that be?"

"Get on your knees and you'll find out," Pipp said, pointing at the floor. Zipp's face changed to something just short of a scowl, but she sank back down to her knees anyway.

As Zipp looked on, Pipp put on the toy, pulling it up her legs until the straps were around her hips and the attached dildo poked out from beneath her skirt. When she was satisfied, Pipp stepped forward, leveling the end of the intimidating dildo with Zipp's face.

Zipp found herself in an entirely new position, staring down the barrel of a cock she rarely even let inside her pussy. "C'mon, Zipp, open wide," her sister said, pushing her hips forward and touching the tip of the dildo to her nose. "Say 'ah'!"

With one last petulant glare, Zipp opened her mouth. Pipp moved forward, pushing the dildo past her sister's lips and over her tongue. She continued in until about half of the dildo had disappeared into her sister's mouth before pulling out. In and out she went a few times, listening to the sucking noises and small vocalizations her sister made on the rubber. If Pipp hadn't known any better, she might have guessed Zipp was enjoying it a bit more than she was letting on. Finally, when the shaft was shining with a coat of Zipp's saliva, Pipp pulled out of her mouth entirely.

"Alright, it's wet now," Zipp said, pouting in indignation as she clenched her hands around her knees. "Can we finally—MGPH!" Pipp interrupted her by grabbing hold of her hair and stuffing as much of the newly-wettened dildo as she could back into her. Zipp tried to close off the back of her mouth with her tongue, but it was no use. The flexible rubber of the dildo surged past her tongue, made the downward turn and sank into her throat.

"This is for teasing me like that!" Pipp said as she kept the dildo in her sister's throat, using one hand on the back of Zipp's head and the other in her hair to hold her in place as she savored her choking and sputtering. Tears of strain appeared in the corners of Zipp's eyes as Pipp wiggled her hips around to grind the dildo against the walls of Zipp's throat, and no small amount of spit leaked from the seal of her lips around the thick rubber shaft.

With a tug on the back of Zipp's hair, Pipp finally pulled the rubber length out of her sister's throat. Zipp immediately bent over and threw herself into a desperate coughing fit, trying to suck in air amidst frenzied panting and coughing as threads of spit dangled from her lips. "H-foly fuck!" Zipp managed to get out as her breath returned to her. "What in Tartarus was that fo—MMMPH!" Pipp grabbed Zipp's hair, pulled Zipp up again and shoved herself back into her sister's mouth, burying the dildo all the way to the base.

After that, it was off to the races. With a tight grip on the sides of her sister's head, Pipp threw her hips back and forth with wild abandon, mashing Zipp's face into her crotch every time she shoved the dildo deep into her throat. The noises coming from Zipp only served to heighten her arousal, spurring the surprise facefuck on to greater speeds.

Zipp's eyes had never been more bugged out. More strained tears ran down her face, adding to the strings of slobber pouring out of her mouth while ungodly noises escaped her throat as it was repeatedly stuffed with rubber cock. Unable to escape Pipp's surprising strength, all Zipp could do was keep a tight grip on her sister's hips, take short breaths through her nose whenever she could and try in vain to relax her throat. "GKK! NGK! GLRK! GLKK!" she sputtered out as her sister continued to savagely rail her mouth.

Eventually, Pipp began to get tired, her thrusts coming not quite as hard or fast, though every last one still managed to push its way into Zipp's abused throat. Soon, Pipp's grip on Zipp's head slackened, giving her an opportunity to push away. The dildo left her mouth for the last time, freeing her up to start another distressed, convulsing and teary-eyed fit of coughing and spluttering. She brought one of her hands up to massage her neck as the soreness in her throat grew.

Pipp kneeled down beside her sister, the dildo still sticking out of her lap. "I'm really sorry, Zipp," she said, an embarrassed blush settling on her already-pink features. "I-I don't know what came over me." Zipp gave a small nod, wiping the tears and spit off her face and giving the occasional cough. Pipp wrapped Zipp in a gentle hug, feeling her sister's chest rising and falling against her own as Zipp's breathing returned to normal. "Do you want to stop?" Pipp asked, her voice barely above a whisper.

Zipp gave a long sigh before straightening up and looking at her sister. "Not a chance, Sis," she said before shrugging off the embrace and getting shakily to her feet. Pipp looked up at her sister, surprised at how quickly she was recovering from the near-violent throatfucking she'd just taken. "If you don't do my pussy as hard as that, I'm keeping your bra as well as your panties!"

Pipp just shook her head and smiled, both grateful she hadn't hurt her sister too much and glad they could continue their fun. "You just might have earned my bra anyway, Zipp."

Warning: I don't even fucking know anymore.

Warning: I don't even fucking know anymore.

Pipp got to her feet, only for Zipp to seize her by the shoulders and spin her around so she was facing away. "Ah! Hey!" she protested over her shoulder as Zipp pulled her jacket off.

When Zipp had managed to get her sister's arms out of the sleeves, she tossed the jacket away before wrapping one arm loosely around Pipp's neck. Her other hand went to the bottom of Pipp's shirt, which she pulled up and over Pipp's chest, revealing considerable breasts contained in a bra with a buckle on the front. Zipp leaned back slightly, pulling Pipp with her and forcing her to arch her back and push her chest out.

As the high of having just facefucked her own sister receded, Pipp let herself relax into Zipp's grip. She raised her hand and pulled Zipp's face forward, turning her own head and tilting it upward to bring their lips together. Zipp undid the buckle of Pipp's bra, freeing her large, pink breasts. Releasing Pipp's neck, Zipp moved both hands to her sister's breasts, squeezing them and rolling her nipples between her thumbs and index fingers.

Pipp sighed through her nose, her eyes fluttering shut as she stood up even straighter. While she kept one of her hands on the back of Zipp's head, the other went down to the zipper of her skirt. Undoing it, she shook her hips to dislodge the skirt, but the waistband got caught on the large dildo still attached to her hips.

Nonetheless, Zipp took notice of what her sister was trying to do and released her, crouching down to remove the skirt herself. While Zipp worked on that, Pipp finally removed her shirt fully and pulled her bra the rest of the way off, rendering her curvaceous figure bare but for her long boots and the strap-on.

The twins paused to take each other in, tracing their eyes over each other's figures and curves as if to confirm that this was real. Pipp had long since ceased to be nervous about their location—any chance to further consummate her closeness to her sister was an opportunity she would never pass up. Zipp, meanwhile, was just glad she'd been able to get Pipp to join her, and was really hoping her days of feverishly fingering herself in the bathroom to mental images of Pipp were over.

With that thought in mind, Zipp broke eye contact first to pull her underwear off, moving the lightning-printed panties over her sock-clad legs and kicking them away. She spun around and braced her hands against one of the tables, bending forward and spreading her legs wide. "Ready for the main event?" she said, wiggling her butt at Pipp.

"The question is, are you ready?" Pipp said as she walked forward and placed her hands on her sister's hips, lining the rubber cock up with her folds.

Truth be told, Zipp always felt a little nervous when she offered herself up to the eight inches of rubber now poking at her pussylips. She was far more used to wearing it herself, which was why it was white, and subjecting herself to the still-unfamiliar feeling of having her pussy stretched around it, of even being penetrated by something of its size, unnerved her slightly. Nevertheless, she disguised it well as Pipp gave a gentle push into her, starkly contrasting the facial rutting she'd subjected Zipp to earlier.

Inches of dildo disappeared past Zipp's entrance, gradually filling her vagina and spreading its walls apart. In spite of her mild discomfort at the idea of getting fucked, her body had been anticipating the act, and her pussy was already wet enough to permit the dildo to slide easily through her.

After a long moment, Pipp hilted inside her sister, the tip of the strap-on coming just short of the discomfort of hitting Zipp's cervix as Pipp pressed up against her sister. She kept herself there, letting Zipp adjust to the sensation of having her pussy wrapped around the thick rubber length.

Soon, Zipp gave a short nod, letting Pipp know to continue. Pipp slowly pulled out of her sister, the dildo glistening with a coating of Zipp's fluids once more as it exited her body. Zipp hummed quietly as the length moved through her, feeling herself contract around it as Pipp pushed herself back in.

Remembering her sister's request, Pipp soon began to quicken her pace. The sound of flesh slapping against flesh began to fill the room, combining with the sounds of a now-moaning Zipp. The rubber length drove in and out of Zipp, going as deep as it could with every push forward and leaving sparks of pleasure in its wake when it pulled back. It was all Pipp could hope for that it felt as great to Zipp as she was used to feeling when Zipp used it on her.

Zipp's pleasure built, her reservations melting away as the thick shaft of the dildo rubbed at every one of her sensitive spots. Her arms were shaking now, threatening to give out, but still she held herself up. She was positively dripping her arousal now, drops of her juices falling to mark the floor between her feet.

Keeping a firm grip on Zipp's waist, Pipp kept hammering into her, moving her hips back and forth at ever greater speeds until, with a cry, Zipp went rigid, her legs shaking slightly as she arched her back. "Hnnnggg!" she groaned, clenching her teeth and squeezing her eyes shut. Pipp kept going the entire time, fucking her sister through what appeared to be her orgasm.

After a few moments, Zipp relaxed, her pale white form going slack as she lowered her upper body to the table top and rested her head on her arms. "W-whoa," she breathed as Pipp slowed and came to a stop.

Pipp slid the strap-on out of her sister and took it off. After a moment's consideration, she put the dildo into her own pussy, pushing it into herself up to the hilt. Slowly, she began to slide it in and out of herself, her sister's leftover juices acting as lubricant as she fucked herself on the length she'd just fucked her own sister with.

[Fuck it, the rest of this is going to suck as much balls as the shit you already read. Feel free to write and publish your own continuation of this "story".]

Warning: Paper-thin plot incoming.

For Pipp Petals, being crowned Princess of the Fall Formal made life no easier. It felt like everyone was waiting for her to do something miraculous, like the fabled Twilight Sparkle and her six friends who'd graduated some years ago. It was almost as if they expected her to fight off a she-demon and stop a zombie invasion by hugging people.

The time between periods when she had to walk the halls to her next class were the most stressful parts of Pipp's days. It felt like everyone's eyes were on her, waiting for something to happen. Luckily, her twin sister Zipp had memorized her schedule, and she was almost always there to walk with her.

Pipp peeked out of the classroom after third period. Lunch was up next, and Pipp hated it almost as much. "Hey, Sis!" Zipp called from the locker she was leaning against.

Pipp's nervous expression softened. "Hey."

Zipp approached, her hand held out. Pipp took it, and they set off down the hall hand-in-hand. "Listen, I know you've been feeling really stressed out lately. Everyone's been staring at you since the Fall Formal and everything."

Pipp gave a small nod. Sometimes, she envied her twin. She could disappear off for long amounts of time to work on some science project without people making a fuss. Meanwhile words of worry spread around if Pipp didn't update her social media pages at least once an hour.

Normally, however, it was Zipp that kept her sane. She was always there with her clashy pink and cyan hair, offering words of encouragement or a shoulder for Pipp to put her head on. It was a shame they didn't share a lunch period—not that Zipp seemed to care much about skipping class.

"Well," Zipp continued, "I got to wondering why we have to wait till nights to have our time together."

"Don't talk about that here!" Pipp hissed. "Besides, what are you even suggesting? That we do it during the day?"

"Yeah."

"Here?" Pipp had to wonder what her sister was thinking sometimes.

"I know, I know, it sounds crazy and stupid. But let's face it: your days are terrible, and they're eight hours long without Mom badgering you in the evenings. Wouldn't a little break during the day help? Besides…" Zipp quirked her eyebrow, taking her hand away from Pipp's and reaching down to grab a handful of her sister's butt through her skirt. Pipp squeaked. "It's hard going without a piece of this the entire day."

Pipp was willing to concede that point once she'd collected herself. "It... It would, I suppose, yeah. But where? We're in school, Zipp."

"I know just the place."

They walked together down some corridors, passing fewer people each time they turned a corner. Soon, the only sound was their boots on the tiles. When Zipp stopped, they were outside the yearbook room. It was nearly always unoccupied during the school day, especially near the beginning of the year, and was thus a perfect place for a horny tryst between twin sisters.

Zipp let go of her sister and opened the door to the yearbook room. Without looking back, she stepped inside, shrugging off her backpack and leaving it by the door. After a quick look around, the shorter of the two followed, closing the door behind her and putting her backpack next to Zipp's.

As Pipp approached, Zipp slipped off her leather vest, leaving a strained off-shoulder top with two pointed nubs pushing against the fabric. "No bra?" Pipp asked, a knowing smile on her face as she brought herself close to Zipp.

Zipp just smirked. "You should try it sometime, Sis."

Pipp drew her sister into an embrace and looked up into her eyes. "I'll leave the experimentation to you, Zipp. For now, let's just—" She cut herself off, pushing her lips against Zipp's. Zipp eagerly returned the kiss, wrapping one arm around Pipp and placing her other hand on the back of the shorter girl's head.

They let their bodies come together, their hands wandering as they savored a closeness neither could imagine sharing with anyone else. Pipp brought her hands to rest on her sister's chest, squeezing Zipp's firm-yet-supple breasts and lightly pinching the nipples through the fabric of her shirt. Meanwhile, Zipp reached one hand down to grab a handful of her sister's ass while the other went under her skirt and rubbed at her slit through her panties.

Pipp gave a little squeak of surprise and broke the kiss as Zipp began to trace little circles on the front of her underwear. "Going straight for the prize, huh?"

"What can I say? You're adorable when you get all flustered."

"Touché, but at least let me get your shirt off before you start rummaging around down there," Pipp said, grasping the hem of Zipp's top.

Zipp chuckled and raised her arms to let Pipp pull the garment over her head, leaving the pale white skin of her breasts and toned stomach bare. She was now naked from head to waist, leaving only her boots and socks, jeans and underwear. "Your turn," she said. "Get those panties off, Sis."

Pipp rushed to comply, hooking her thumbs in the waistband of her panties and dragging them swiftly down her legs. She moved them past her boots before pulling one foot at a time out of the leg-holes. Zipp bent down and snatched the underwear away, quickly finding the little wet spot she'd expected. "Heh, I guess someone is excited," she said with a triumphant smirk before bringing the panties to her nose and taking a long sniff. "And to think you didn't want to even talk about doing this at school a few minutes ago.

"I'll tell you what: I dare you to leave these with me for the rest of the day."

"What!? Are you crazy?" Pipp said, blushing furiously. She was still nearly fully-clothed, but that new breezy sensation down there was already making her feel more exposed than ever before. "Do you see how short my skirt is?" For emphasis, she pulled down on the hem of her skirt. It only reached a third of the way down her pink thighs. "What if someone sees me down there and posts it online?"

"Uh-oh… Is my sister a chicken?" Zipp placed her hands on her hips and tilted her head to one side. She had her chest pushed out slightly, putting her more-than-eye-catching breasts on display as if daring her sister to match.

Pipp ground her boot against the tile floor and clenched her fists by her sides, a pout coming over her face. She almost felt silly about making a fuss over losing her panties when her sister was standing there with her tits out. "Rrrrr… fine. But if I catch you wearing that vest today, you're taking bottom for once tonight."

Zipp just laughed and said, "Deal!" before tucking Pipp's panties into the back pocket of her jeans. She pulled Pipp back into their kiss, letting their tongues dance together amidst a nigh-heavenly chorus of soft moans.

Keeping their lips together, Zipp lifted her sister up onto one of the stools and spread her legs. Pipp's neatly trimmed pussy wound up on full display as her skirt stretched taut between her thighs.

Zipp pulled away. Pipp leaned forward, trying to follow, but Zipp soon moved out of reach. Opening her eyes, Pipp watched as Zipp pulled off her boots. With a wink and a wiggle of her eyebrows, she turned away from Pipp and bent forward at the waist. Undoing the button and zipper of her jeans, she kept her rear high in the air as she slid them over it and down her legs, leaving nothing but her underwear, which had a picture of a crowned lightning bolt striped pink and cyan like her hair, and an unexpected pair of knee-high socks.

"D'aww…" Pipp brought a hand to her chest, her expression going soft. "I didn't think you were one to dress for occasions, Zipp," she remarked, leaning back in her chair while keeping her legs spread.

"Yeah, but this one's really special, don't you think?"

Walking back over, Zipp got to her knees before the sister she loved and brought her face level with the pussy she craved. Pipp watched as Zipp leaned forward, first planting a kiss on her inner thigh. She gradually moved upward, leaving a trail of kisses on her sister's pink skin. Pipp pulled the bottom of her skirt up, allowing Zipp easier access as she reached the joint of Pipp's thigh and crotch.

Bringing her hands up, Zipp spread the lips of Pipp's pussy and pushed her tongue inside, earning an appreciative moan from Pipp. She curled her tongue upward and dragged it outward through Pipp's pussy, finishing off by flicking her clit. Pipp grunted and shifted in her seat, pushing her hips forward. She placed one of her hands on the back of Zipp's head, moving her fingers through her sister's short pink hair while the other hand undid her own jacket, letting it fall open before she pulled her shirt up over her bra-clad breasts.

Acquiescing to Pipp's tactile request, Zipp pushed herself forward, burying her nose in the little tuft of purple hair nestled just above her hood, and began to lap more at her sister's pussy, alternating between pushing her tongue into Pipp and placing long licks along her entire slit. She took her hands off of Pipp's legs, moving one away to play with one of her tits while allowing the other to slip between her legs and into her panties. Slowly, she pushed her middle finger into herself while gently pinching her clit between her thumb and index finger at the same time. She hummed in pleasure against her sister's pussy, drawing further moans from Pipp, who braced her hand harder against Zipp's head and pushed her deeper into her crotch.

Things continued as such, with naught but wordless vocalizations floating through the room as Zipp serviced Pipp. Pipp had long since stopped uttering such contrivances as "Keep doing that" or "That feels amazing" whenever Zipp did this—she knew she was wrapped around Zipp's finger as much as her pussy was wrapped around Zipp's skillful tongue. She was also well past stating when she was getting close to cumming—Zipp had eaten her sister out enough times to see her orgasm coming from a mile away.

Instead, Pipp just sat there on the stool with her eyes closed, floating away from her inhibitions on waves of incestuous pleasure. She didn't even notice that they were situated directly in front of the door to the yearbook room so anyone could look in and see the sister-on-sister lewdness happening in the middle of the school day.

But, just like that, it all ground to a halt as Zipp pulled away, moving her head out her sister's grip and standing up. Pipp opened her eyes and frowned. "Wha— why'd you stop?"

A wide grin spread across Zipp's face. "You'll see…"
