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…"
