Zippi's voice was loud, sweet, and high-pitched enough to carry from the back of a crowded room, but in this case, it needed only navigate the few foals standing between her and Miss Cheerilee, who was at the front of the class and wearing the same tired, overly-taxed expression common to instructors everywhere when attempting to wrangle a herd of foals anywhere not in their normal schedule. It was like herding sticky, trouble-making, particularly talkative cats. Cheerilee loved cats, but even her willpower had its limit. The foals of Ponyville Elementary (who seemed to gather and split into appropriately-sized classes as warranted, something like an amorphous amoeba) had followed Miss Cheerilee this morning to the local museum, a destination that had been planned by PTA (Pony-Teacher-Association) decision months in advance. Of course, this had no bearing on foals like Zippi, who viewed 'permissions slips' as 'optional' and 'homework' as 'those funny pieces of paper the teacher keeps giving out and then asking to get back'. If she wants them so much, why doesn't she just keep them in the first place? "Everypony was instructed on their permission slip to bring enough food for the day," Miss Cheerilee said, her voice already aching with exhaustion, much like her body would no-doubt be by the end of the field-trip. "If you forgot to take a lunch with you, I've brought enough vegetables and crackers to share with everyone—" "What about candy?" Zippi interrupted. "I bet there's a part of the museum dedicated to the ancient history of candy in Ponvyille or something. Can we get a free sample there?" "There's no section on ancient candies," Zew said quietly. No matter how much she mumbled, her sister always seemed to hear anyhow. "We're starting with a presentation on the founding of Ponyville, then going to the Everfree Entities exhibit, then finishing with the demonstration on modern engineering. There's a train ride." Zew gave her sister a look which didn't qualify as a glare, but maybe more of a softened 'hmmph'. "It was all in the schedule. If you read it." "Hmmph." Zippi wasn't nearly as courteous as her sister, and therefore seldom made an effort to hide her disappointment with the banality of daily life, especially when school was involved. "Are you saying that if I didn't read the schedule, that it had something different in it? Like, the contents of the permission slip care about whether or not I read them? That's some Hoofenberg's Uncertain thingummy right there." Zew raised an eyebrow. "Where did you even learn about that?" "Zeta yelled it at me the other day," Zippi said, twirling her wand in her mane absentmindedly with a free hoof. "I was running around the house, and she said something about going so fast, she didn't even know where I was anymore. Then something about apple pie? I don't remember most of it." She yawned and scratched the back of her head. "You should be quiet or you're gonna get in trouble," Zew said quietly. Zippi shrugged. "So? Just a better chance I'll get to go home instead of stay here on this stupid field trip." "Aw, come on. It's not so bad." Zew gave her sister a soft pat on the back. "There's a section of the museum on Equestrian constellations and celestial bodies—not that kind." Zew caught her sister's eyes lighting up, likely picturing an exhibit filled with pictures of the Sun Princess's royal be-hind. "You and your stars," Zippi said, her tone mostly joking. "What if there's an anatomy section? We could take over for Miss Cheerilee as a tour guide and put on a show for the rest of the class..." "Ahem," Miss Cheerilee said, either having finally overheard enough or just deciding to put her hoof down when it came to the two girls and their ongoing conversation. She was willing to let select instances of volume slide, and usually the pair did a pretty good job of keeping their dialogue to themselves. But sound carried further in a mostly-empty museum with insulated indoor acoustics, and Cheerilee was even more wary for trouble-making than on a normal schoolday. One breach in the dam could have unspeakable consequences for the rest of the schedule. They might not even make their first bathroom break on time. Cheerilee shut her eyes and shuddered at the collective memories of classrooms full of fillies, squeezing their legs together and raising their hooves in unison before abandoning their school-room patience and barreling out the door like a horde of ravenous timberwolves. Not again. Not today. Cheerilee waited until Zippi and Zew looked sufficiently chastised together, then cleared her throat and raised a hoof high over the heads of the class. "Alright," she said, as clear and calm as she could muster. "If everypony is done talking, it's time to get on with our tour. The normal tour guide, er, Bristle Brush, isn't here today, but I've been reading this pamphlet since last night, so..." Cheerilee smiled awkwardly and gestured to the dusty expanse of the museum like a hostess on a game show revealing the grand prize. "Let's begin our exciting exploration of Equestrian History!" The class let out a collective groan, with Zippi's voice the loudest in the throng. Zew simply sighed and stared at her hooves. As much as she enjoyed following rules, there was no appeal in a tour of the museum that didn't begin with her heart-throbs from the night-sky. Even as is, Miss Cheerilee had only half-promised that there might be time at the end of the field trip for her to check the astronomy wing, and that the time available might be dependent on how well-behaved she and her sister were throughout the day. Zew sighed again, but prepared to follow the rest of the class down the hall to their first exhibit. She already knew about the founding of Ponyville. Everypony did. Most of them had probably learned about it in this very museum anyway. "Psst," Zippi said, somehow managing to be shrill and conspicuous while whispering. A few other foals looked, but Zew knew the signal was for her, and broke off from the group just a few steps behind to talk with her sister. "What is it?" Zew asked. Her wand was currently serving as a bookmark in her school binder, but she found herself wishing she could take it out and chew on it between sentences. She liked the vaguely-sparkly, flavorless sensation that came with the left-over magic residue. "Why don't we ditch the snore-squad and go explore the museum ourselves? I bet we could find something totally awesome!" Zippi's eyes lit up with stars as pictures of ancient pony fighting gear flashed through her head. "Miss Cheerilee said there'd only be time for the astronomy wing if we were well-behaved," Zew said, quiet and thoughtful. "And you believed that the amount of time in a day depended on us?" Zippi laughed and blew a raspberry with her tongue out. "If that was true, the day would never end, so we could stay up and have fun forever." "I'd still want the night to come out sometimes," Zew said, nodding along with her sister's imaginings. "Maybe once a week, near the end." Zippi nodded back. Her wand glimmered and spat out tiny sparkles onto her mane. "We'll have plenty of time to check out the astronomy wing if we go on our own," Zippi said. She was already starting to lead the way in the opposite direction from the class tour, inspired not by any particular aim or purpose besides general mischief making. And the astronomy section, eventually. For her sister's sake. "But won't Miss Cheerilee notice we're gone?" Zew asked. Zippi rolled her eyes and blew a strand of mane out of them afterwards. "Pfft. She only does a head count at the beginning and end of class. We'll be fine as long as we're back before the end of the day." Zippi held out a hoof towards her sister and smiled a sweet, seductive, sisterly smile. "Come on. You wanna have fun with me, don'cha?" Zew smiled softly and blushed a little. "You know I do." "Let's go then. Before anypony hears us blabbering." "But I think somepony already—eep!" Zew's adorable squeal trailed off down the corridor as her sister dragged her along in search of an exhibit more fascinating to examine than either of the two them. "Do you think we could use one of these fancy telescopes to spy on somepony in town?" Zippi asked. She was poking and prodding haphazardly at one of the telescopes in question, which, if she'd bothered to read the neighbouring plaque, she would have realized was only a to-scale recreation of Equestria's largest telescope, at a 1:10,000 ratio. Zew scrunched up her mouth and blew a puff of air out of her nose. "That's not what they're for," she said huffily. "They're able to see millions of miles away in empty space to locate stars and planetary bodies. They're not for snooping on the pony next-door. Use binoculars for that." Zew had only as much patience for fussing over her sister as there were stars in the universe, but when those stars were right next to her, Zew found it difficult to pay attention to anything else. A single constellation was enough entertainment for weeks—the entire sky was limitless in its potential. "Look here," Zew said quietly, remembering to keep her voice low even though there was nopony immediately adjacent to notice them. Zippi skirted over beside her sister, always willing to attempt at least a cursory interest in outer-space stuff, as much for her sister's sake as because sometimes, space stuff turned out to be really interesting. Zew gestured to a glowing, translucent image being projected over a smooth, black glass, hovering above it like a hologram. Zippi reached out and poked the image with a hoof, and it wobbled in and out of focus before finally sliding back into readjustment. "Cool," Zippi said, her eyes wide. Zew smiled at her. "This is a map of the whole Equestrian sky as far back as anypony can remember... see how it started out different, before the cities were built, when you could see everything in the sky? And then as the ponies started finding their own light sources, the stars were harder to find, and the night's sky got muddier and darker by comparison..." Zippi nodded, but only halfheartedly—beyond her control, a feisty, trouble-making streak would always urge her away into something else more occupying. It wasn't exclusive to her sister, or the stars—focusing was an art Zippi had yet to master, whether it was casting magic or paying attention in class. The only thing exciting enough to keep her attention for extended periods of time probably didn't have an exhibit dedicated to it any where in the museum. There was a lot else in the astronomy wing—but it all involved craning your neck high to look at far-up objects, or looking at drawings of lines between tiny points of light and going "Ooooooh". Zippi's attentions often drifted more easily to things that were more close by. More tangible. Hmm. It would be a while before the class was done their field trip, and while the two of them were guaranteed a modicum of privacy due to the fact that nopony else was likely to just be passing through the boring ol' museum in the middle of the day, that wasn't to say that there couldn't be just one old muddling fuddy-duddy there on their monthly-pass, choosing exactly the right inopportune moment to pop out behind an exhibit and catch two unsuspecting fillies in the middle of something they were not supposed to be doing. Zippi scrunched up her mouth and tapped at her chin with her hoof. Hmm. Hmm indeed. This was going to take a bit of care to get right. Zippi started by patting her sister on the rump. Not loudly, but enough for the tiny, satisfying 'smack' to echo faintly through the spacious room. Zew barely seemed to notice at first, but eventually turned her head with a look Zippi translated as 'mild amusement'. "Hmm?" Zew found it hard to pull her eyes away from the display card which she was reading for the second time, with extra attention to the translated words and citations at the bottom of the card. Her sister tapping her on the butt didn't necessarily mean anything other than 'hey you'. The second tap suggested a little more. Her sister squeezed this time, not rough, but hard, enough to bring out an involuntary little 'eep' from Zew's mouth, and cause her to blush afterwards. Then the third slap, the smack to her rump, was certainly intentional in that direction, and Zew found herself with that hot, embarrassing tickle in her chest that happened when she and Zippi were about to have 'fun' with each other. "Zippi," Zew whispered, still conscious of keeping her voice low even though her sister's hoof-smacks were free to bandy about in volume. "What are you doing? Somepony could hear us." "Not if we're just quiet enough." Zippi leaned forward, standing behind her sister, until her face was level with Zew's ear, so she could drawl out her statements with tantalizing proximity. Zippi gave her sister's ear a playful lick and was rewarded with a gasp and a shiver, as well as the persistent aroma of lavender cookies mixing with peaches and cream. Her sister's unique scents always reminded her of a devilish breakfast with cookie dough somewhere in the medley. Zippi giggled and licked her sister's ear again. Zew did her best to hold in her moan, which was a quite decent effort, only letting out the little 'mmm' at the end. Her sister's body was warm, pressed against her from behind, and she found herself relaxing backwards into it. Shivers kept running down her spine when her sister licked at her ear. That was one of her special spots. "We can't just do it in the middle of the museum like this," Zew said, rapidly recalculating her angle of argument from 'We shouldn't do this at all' to 'We shouldn't do this at all but let's do it anyway as long as we don't get caught'. Zew let out a full-blown moan, and the sound rebounding off the walls and back into her ears made her face flush bright red. "Can't we find a private room, or—" "Way ahead of you." Zippi pulled away from her sister, albeit slightly reluctantly. She'd spotted the half-open door to the janitor's closet the moment they'd walked in, and filed it away for later as a potential source of mischief. Really, what better place to drag your filly-sister off to for twin makeout hijinks? Zew let herself be led towards the closet by her sister, feeling that she was more a particle caught in the orbit of a comet than anything close to a comet herself. Her sister was burning bright today, and it was hard not to shield her eyes by instinct. "Perfect," Zippi said. The two of them fit snugly into the closet, stocked as it was with buckets and mops and unlabeled cleaning supplies which had long ago lost their identification. There was probably room for a third pony about their size as well, but since nopony else was there, the two of them shut the door together, and began to settle into the musky dark. "It's kinda smelly in here," Zew said. She couldn't quite place the fragrance. Certainly nothing as nice as her sister's raspberries and vanilla. "Come here and smell me instead then," Zippi said with a giggle. She reached out and pulled her sister closer with a hoof around the back of her neck, and soon the two of them were cuddling while resting atop a large pile of coats and miscellaneous clothing items piled up, possibly in an impromptu 'lost-and-found'. For now, it was a pillow and a bed, and Zippi and Zew sighed into each other, eyes closed, finding the relaxing warmth of each other's bodies even in the most remote and unlikely locations. They cuddled like that for a while, neither one saying anything, until Zippi's hoof started to move, almost on its own. The two of them were like that, stationary, breathing softly, until Zippi's hoof began to trace gentle lines along Zew's foreleg. So light and gentle it left goosebumps, and made Zew's coat stand up on end, and her head feel all fluffy and shivery. Zippi's hoof seemed more interested in exploring than any particular destination. It roamed like a gentle intruder over Zew's back and shoulders, rubbing the base of her neck to a cascade of hushed moans, then moving up and running through her mane, the lavender and cookies once more managing to overtake the closet funk. When Zew took a deep sigh in, her sister's strawberry mane scent filled her lungs, and she let out the big breath sounding content, and more relaxed by the minute. When Zippi's hoof moved between her sister's legs, Zew caught herself biting her lip to keep from shouting out. Expecting anypony to be quiet for this part seemed unreasonable, in Zew's humble opinion. "Hey!" Zew sounded startled while still managing to keep her voice at a somewhat subdued volume. "What are you doing?" Zippi giggled as her hoof continued its arc up and down inbetween her sister's legs. "What," she said, "you didn't think we were just gonna come in here and talk about stars, did you?" Zew rolled her eyes, a difficult feat between gasps and wriggles, but one she managed regardless. "No," she said, huffily, "not that. You're not giving me a chance to fight back." Zippi smiled mischievously and stuck out her tongue. "So? Who said I have to do that?" "Nnnh..." Zew murmured and bit her lip again as her sister's hoof ran distinctly over her underage slit for the first time that day, getting a chance to feel the already slight developing dampness. "Why don't we play—nnnh—why don't we play 'Hornsies'?" Zippi could have pretended to ignore her sister and kept on with her assault until the two of them were a wrangling around ball of filly-sex, but she couldn't refuse a request for 'Hornsies' no matter the circumstance. It was her favorite game, and her sister's too. Reluctantly, Zippi withdrew her hoof from between her sister's legs, following a deep sigh from Zew's lips. Zippi kissed her sweetly on the forehead before giving her a little space in the slightly-cramped closet. "Alright," Zippi said, spreading her own hind-legs and showing off the pretty pink hiding between her mellow grey. "Do you wanna go first?" "By go first, do you mean—" "I mean go first... like, give the Hornsies." "Oh. Well, yeah, then, I wanna go first." "Okay. You get five minutes." Zippi pulled her wand out of her mane with her hoof and placed it in her mouth. She swished the wand around in a circle until a faint orange glow began to emerge, then pointed it at the ground next to herself. The orange glow continued to swirl and solidify until it was a small, egg-shaped timer, which Zippi picked up smiling. She turned it until the little dial was five minutes up, then set it down on the floor again. "Good luck," Zippi said, grinning. Her sister nodded. Her eyes were narrow, shimmering with a deep, almost imperceptible determination. With only the few seconds wasted to take one last deep breath, Zew opened her mouth and took the tip of her sister's horn inbetween her lips. She extended her tongue and licked around the pointy-but-rounded tip, and was immediately rewarded with a tiny sparkly taste tinged with a hint of lemon. This would have made her smile if her mouth wasn't busy with something else; the first taste of lemon sparkles was sort of like her sister's 'horny' pre-cum—she only got the privilege of feeling it on her tongue if she was using it properly and her sister was enjoying it. With her eyes half-open, even from a cursory glance, Zew could tell her sister was already regretting not going first. Zippi was also much worse than Zew at being quiet, both naturally, and on command. Her whimpers started small, but the more Zew licked and sucked at her horn, the more her eyes clouded and her head filled with fuzzy, heart-pounding vapour, and the harder a time she had holding back her moans and squeals. At the same time, Zippi hated losing, and showing any sign of weakness this early into their game was practically doing just that. She did her best to grit her teeth and bare through the lightning jolts of pleasure that came in syncopated waves along with her sister's attention—the way Zew sucked at her horn was so timid and adorable, it made her feel almost guilty, like she was taking advantage of an invisible innocence. In reality, Zew just knew how to push her sister's buttons, and she also knew that if at any point during a round of 'Hornsies' Zippi opened her eyes and saw her sister's darling submissive pout, the perfect face of 'Did I do a good job?', it set something off in her, like throwing a match into a barrel of gasoline laced with porno mags. 'Yes,' Zippi wanted to say, felt it climb out of her throat. 'You're doing such a good job.' "Mmmnh," was what came out of her mouth as a compromise. Words could do a good job of hiding sometimes. But her body was harder to hide, especially when Zew was right next to her, with almost no room to wiggle away and breathe for a moment. Zippi knew the egg-timer was still there, she wasn't sure how accurate it would be, or whether or not it would continue to function if she lost control and accidentally let her sister win all of a sudden— Brrrzzzzzzzzt. Five minutes. She'd made it. The little 'ah' sound Zew made as she meekly removed her mouth from her sister's horn sent a jolt straight between Zippi's legs. Her little puss was beginning to soak the clothes they'd piled underneath as cushions. "Ha," Zippi said. Her shaky breathing made her sound less confident than she wanted, but she could look just as determined as her sister. "Made it," she said, then took in and let out a deep breath. "My turn now." "Good luck," Zew said. She picked up the egg timer and turned the dial, then set it back down and tilted her head forwards, presenting her horn and the swirly pink of her mane. Zippi made as though she was about to lean forward and plunk her mouth squarely down on her sister's horn, but just before the point of contact, she dove to the side and grabbed the egg timer, which her sister had set conveniently slightly further away than before. "Ah-ha!" Zippi shouted. Zew glared at her, and Zippi made an apologetic scrunchy face back. "Sorry," Zippi said, much quieter this now. "But I caught you! This is only set to four minutes!" Zew looked at the egg-timer, then from side to side in either direction, as though there might be somepony who would appear there to relieve her of the burden of explaining her duplicity. "Uh... are you sure you didn't move it when you picked it up?" Zippi gave her sister a glare that felt so strong it might have had a little bit of magic behind it. "Alright, alright. Fine. You caught me. I'm sorry." "I get two extra minutes as a penalty," Zippi said. She turned the timer without waiting for her sister's approval, to a healthy seven minutes. Zew sighed, but nodded, resigned to her fate. "Fine," she said. "I'm sorry I cheated." "Aw, it's fine. I was actually just gonna turn it off before I noticed you cheated, so no hard feelings." Zippi and Zew grinned at each other. This was fun. Who needed some stuffy museum tour anyway? "Strap yourself in," Zippi said, licking her lips. "This is gonna be a messy one." "Oh, no," Zew said quietly. "You know how much I like—ahhh!" Zew couldn't help herself from letting out a moan at least as loud as any shout her sister had made in the last half hour. Without warning, and faster than Zew could properly react to, Zippi had dove straight forward and gobbled the entirety of Zew's horn down her throat in a matter of seconds. What's more, is that the instant she'd planted her lips at the base of her sister's horn, her tongue had gone to work in swirls, and her lips hard parted, and she'd started drooling all over Zew's horn, and a little bit had dribbled down her forehead and onto her nose, but that was understandable, really, hardly preventable, and any way every time Zippi started drooling and slobbering and licking her horn up and down like a filthy little filly-foal slut it just got her going so bad... "Ahh! That's... that's cheating!" Zew protested only verbally, not even managing a playful swat in her sister's direction. Zippi smirked with her lips around the tip of her sister's horn, her tongue already coated in spurts of sparkly banana magic residue. "Mhm," she said, giving an extra big lick around the very tip and making her sister moan and shiver. "I don't think so. I think what you did with the egg-timer was cheating, and that's why you're being punished." Zippi licked and slobbered up and down her sister's horn with a noise like schlurp, schlurp, and each time she made it, her sister would echo with a frantic, tiny cry, like a call and response game that made both of them squeeze their hind-legs together in unison. Zew liked to think of herself as a filly with a plan for most scenarios, but being holed up in a janitor's closet with her sister going down on her horn like an oversexed prostitute... well, it wasn't something she'd factored into her potential of daily outcomes, to say the least. Now, if you add something like, a janitor coming back to the closet for his mops to the whole mix, things got even harder to figure out. Luckily in this case our janitor happens to be particularly slow. It took him a full minute to notice the door was closed instead of open, the way he'd left it, and another minute to decide what to do about before he finally reached for the door. It was therefore that the girls heard him mumbling to himself just outside the door long before he'd begun to turn the handle. Unfortunately, 'quick thinking' is not a natural trait of the brain mid-'Hornsies', and so the girls barely managed to share a scared look and gasp between them before the panicked scramble for 'what to do' began. "Shoot," Zew said, looking around for something to hide the pair of them. "This is bad, this is really bad, what if he see us, what if he hears us? What if he—ahh! Cut that out, Zippi! Help me think!" Zippi had been listening to her sister, but all the while continuing to bob her head up and down, managing as much of it in her mouth and throat as she could fit before going back up for air again. At her sister's admonishment, she reluctantly removed her mouth, but did so with a pouty frown to show she wasn't happy about it. Still, her sister had a point. If the two of them didn't figure something out, their playtime might have an abrupt and unsatisfying ending... "Here," Zew said, whispering. She had grabbed a bunch of old coats, the sort that were really fuzzy and bristly and heavy and had more pockets than either of the twins did naturally. Zew passed a few to her sister, and the two of them went to work piling the garments up so they couldn't be seen. There were certainly enough coats to work with, and after adding a few more, they shuffled backwards in the closet as far as they could go, away from the tools and cleaning supplies and hopefully not visible to anypony or janitor who might be peeking in on them. "Could swore I left the darn thing open," said the voice on the other side of the door. It sounded almost geologically old, as slow moving as a rock in a desolate canyon. Eventually, however, the door did open, with an ominous creek. Then the old janitor pony peered in. He didn't seem to notice anything amiss. And so he went to work filling up his mop bucket. As he was filling it up, Zew had a chance to get a look at his cutie mark. It was of a sad, old looking pony, hoisting a mop out of a mop bucket. And... if she squinted, Zew could see, on the cutie-mark pony's flank, another cutie mark, of a sad, old pony, hoisting a mop out of a mop bucket. And on his flank was another cutie mark, of another sad, old pony, hoisting a mop out of a mop bucket. And on his flank... It would have made Zew's head spin, if her head had gotten a chance to focus on it. Instead, her sister's mouth was back. She'd manage to slide down the entire length of Zew's horn without making a sound. Zew, on the other hoof, wasn't so lucky. She'd caught herself moaning, that much was at least true, but even muffled through her hoof, the sound was still so distinct, so desperate and gentle and on fire with pleasure, Zippi could have picked it out of a crowded room at a thousand yards. The only thing the two of them could do was hope the old janitor's hearing wasn't specially attuned to the sound of young fillies playing 'Hornsies'. Or to anything, if they were very lucky. Zew held her breath. She squeezed it down in her chest, praying that it might help her hold in the noises that normally came with her sister's attention on the top of her head. She could feel her legs beginning to shake already, there was something about the sheer stupidity of her sister continuing their game when somepony was right there, it was one of those delicious reasons she loved her, all silly and intoxicating and full of mischief. Zew didn't know how much time was on the egg timer now, if they'd remembered to stop it as the janitor came in or if it was still running, but she could feel her loss about to come on as sure as anything, and if she didn't bite down on something like her own hoof or a musty old coat very soon and very hard, she was going to get both of them caught any second. To her credit, Zippi did pass a coat along, to perhaps to prove as a more effective muffling device. But she didn't stop her attention on her sister's horn, and her tongue went into overdrive, managing to somehow stay silent while licking and slurping sloppily all up and down Zew's horn. At once, three things happened: The egg timer went off. Zew moaned and bit down on the coat as she started to cum. And the janitor pony pulled an old, clunky bucket down from a top shelf and let it tumble noisily onto the floor, masking the sound of the timer as Zippi switched it off, and the loudest part of Zew's orgasm, which had tapered off as the sensation passed from 'overwhelming' to 'blissful ocean waves'. As usual, Zippi had gotten a mouthful of banana-sparkle magic spurt. It wasn't like cum, exactly, either a filly's or a colt's, but it reminded her of the sensation after a blowjob all the same, because the process and return on investment were very similar. You bobbed your head, eventually, your mouth got sticky. And you won at 'Hornsies', if you were really good. Zippi licked her lips, swallowed the somewhat slimy residue left in her mouth, and finally released her hold on her sister's horn, giving her room to come down from her orgasm and breathe through shudders as the janitor busied himself with his bucket. The clanking and clunking about went on for a minute or two—the janitor was as slow at getting his cleaning supplies as he was anything else—but eventually, after he'd seemingly amassed the necessary arsenal to remove an erstwhile piece of dirt, the janitor turned and left the closet, wheeling his bucket along with him, and leaving the door distinctly half-open, the same way it had been when the girls first found it. "No fair," Zew whispered, her face flushed and her breath warm. "You kept going when somepony showed up. How was I supposed to keep from cumming?" "That's your problem, not mine," Zippi said with a smirk. "Anyway, you know the rules." Zew sighed. "Yeah," she said with a nod. "So what do you want?" "I want you to eat me like a banana sundae," Zippi said, still grinning as she laid down and spread her legs. Her pussy glistened with moisture, even in the dim lighting of the half-closed-off closet, and Zew, despite the sting of losing, couldn't help but lick her lips at the sight. "Alright," Zew said. "But be quiet. We could still get in trouble if somepony hears us." "Does that mean you wanna shut the door first?" Zew blushed. She'd already been getting into position to dive between her sister's legs and give her a tongue-lashing. Sometimes remembering was hard when you'd just cum. "Right," Zew said. She quietly pulled the door closed, rationalizing that it would be no problem to leave it cracked open again once they were finally done playing. With the door shut, Zew turned back to her sister with fire in her eyes and an uncharacteristically fearsome smile. "Now," she said, "I'm gonna pay you back for that horn-job." "I hope so," Zippi said, putting her hooves behind her head and grinning. Even though she'd lost at 'Hornsies', Zew didn't catch herself feeling very down about it. Something about the electric sparkle that transcended even magic was in the air whenever she got to play with her sister, and the idea of 'winning' between them was more a token to pass back and forth than any real goal they could fight over. Everything got easier when you just focused on what it was you were doing and why you wanted to do it. "Ooh." Ever-incapable of complete silence, Zippi couldn't keep herself from letting out a little moan just as her sister's mouth came to hover over her little slit. She could feel the heat of Zew's breath touching against her lips, the same heat that must be radiating back, the faintest hint of cinnamon blending in with the already delicious sugary-swirl of Zippi's mane and coat. Diving in nose first was like plunging your head into a cookie-jar full up with perfume. Zew picked up her own wand and gave it a tiny flick before setting it back down. The almost invisible cloud of ethereal yellow magick dissipated into the air, with a tiny trace of sparkles hovering down and landing atop the two fillies on the ground. Zippi noticed the sparkles even through the haze of her arousal, and her eyes widened as the little drifting particles descended to the ground. "What was that?" she asked. "Just a little something to help muffle the sound," Zew said. "Oh," Zippi said. A moment's pause. "Why didn't you just do that earlier?!" Zew shrugged. "I guess I wasn't really thinking at the time." "Your head was still up in the stars?" Zew nodded, smiling. "Exactly." She prodded gently against the base of her sister's pussy, and Zippi's whole body shivered in response. "Mmmm... come on, don't tease me so much." Zippi wiggled her hips, trying her best to shove herself up against her sister's mouth, but only half-succeeding, catching a tiny press of flesh to flesh that made her back arch, before her sister pulled away again. "I'm just getting you back for cheating at Hornsies." "I thought we agreed that we both—ahh!" Zew had started licking, finally. Always subtler and more gentle than her sister, no sounds of slobbering or desperate, wanton laps, but like a kitten, a tiny little nub of pink extended from her mouth to trace softly up and down Zippi's dripping slit, touching her on one side, then the other, leaving the tingle of traced circles around her clit. Every movement was like a string pulled in an orchestra, and Zippi's moans painted the colour of a symphony, nestled safely in the tiny bubble of sound within the closet. Zew could help herself no longer, even if teasing her sister was more fun than giving her what she wanted—eventually, they would both want the same thing, and besides, there was only so much time left before they needed to sneak back into class anyway. With one last restrained, playful smirk, Zew shoved her head inbetween her sister's legs and went to town on her twin's pussy. Tingles of cinnamon grew stronger, and Zippi wrapped her legs around her sister's head to keep herself in place, lest she shiver and buck away into another part of the closet without assistance. There wasn't much dialogue between them. Banter was more for before and after than during, the things they had to say to each other diminished in proximity to the peak of their orgasm, and when it got close, and both of them could feel it, the tingles would run up both their spines, and it was like pushing a boulder the last little bit up a hill before it toppled and tumbled down the other side, picking up speed beyond belief and crashing away into the horizon. Zippi's moans would get a little higher in pitch each time, and then drop back down, and begin to climb again, each time with the squeezing of her hind-legs around her sister's head tightening, and the trickle of moisture seeping out of her slit onto her sister's mouth dampening by the minute, and whether or not there was anypony around, Zippi couldn't often help herself, she was very, very bad at being quiet when it came to this, this part in particular, her sister's tongue, it was going up and down her clit pressing down so hard each time, and that was the last bit it would take— "Zew," Zippi gasped, planting both hooves in her sister's mane and holding on, lest she float away in the aftermath. "I'm gonna—" Zew gave her sister the briefest nod before grabbing Zippi's wand and shoving it in her mouth. By instinct, Zippi bit down, and that plus the spell was the best either of them were going to do to contain the sound of Zippi cumming like a storm after lightning. Muffled through her wand, the sound came out like: "Mmmmhmmmmmmmnm!" Zew couldn't hear it very well, with her sister's legs clenched over her ears. She was mostly focused on keeping her tongue moving, anyway. When the shudders and shivers stopped, the two of them collapsed either side onto their piles of clothes. For the first time since they'd entered, the closet was full only with the sound of soft breathing. The air ran through with every colour of scent, the two of them and their sex smells mixed up like a busted spice rack. It was a few minutes before one them got up. Zippi first, then Zew, each still panting a little, with soft smiles that always came when one of them had done the same. "Thanks," Zippi said, smiling, and giving her sister a pat on the head. Zew giggled, but shook her head as well. "I keep telling you, you don't have to say 'thank you' after, no matter how good it was." "Well, if I ever make you cum that hard, I'd appreciate you saying 'thank you'." "Oh, shush." Zew giggled again and booped her nose into her sister's. The two of them shared a laugh, contained and bouncing in the tiny, sealed off closet. "Come on," Zippi said after their laughter had settled. "We've still got half an hour before the field trip ends. We should be able to sneak back into class if we find out where they are." "The last part of the trip was the exhibit on modern engineering." Zew stood up and kicked her pile of clothes inelegantly further into the closet. Zippi did the same after she got up, until the evidence of their tryst remained only in the left-over scent of sweat and bakery-esque filly-smells. "Let's go," Zew whispered. "And remember to try and be quiet." "No problem," Zippi whispered back. She shut the closet door behind them, then caught herself, and remembered to crack it open again. "Quiet is my middle name." "No it isn't," Zew said with a scrunchy face. "We have the same middle name, doofus." "Shh! No more talking until we get back." "But I—" "Shh!" The pair of them didn't have to wait long for a moment to slip into the back of class—everypony was running around imbued with end-of-day chaos in their step, fascinated by the moving displays and potential train-ride. Miss Cheerilee was off to the side, doing her best to balance her head straight up without nodding off against the museum wall. Every once in a while she'd fail and slip into a brief state of unconscious bliss, then snap back after a few seconds with a startled gasp. Zippi and Zew were all smiles as they snuck in to the engineering wing, and immediately began entertaining questions about where they had been all day from the few foals who weren't lucky enough to be on the train ride. Miss Cheerilee only did the headcount at the end of the day, they explained. She won't have even noticed we were gone. Actually, one of the other students began, as soon as you left, she— "Zippi, Zew? I'd like a word with the two of you after our field trip is over. Please meet me outside the museum entrance once we're done here." By habit, the twins shared their customary 'I guess we're in trouble' look. "Do you think she knows about the closet?" Zippi whispered to her sister. "No. But do you think this means we won't get to see the astronomy wing again?" Zippi rolled her eyes and sighed. "You and your stars." "I'm just saying! We got distracted before I could finish checking out the section on potential space travel developments." "Why don't you ask Miss Cheerilee about it after class." "Alright, no more talking until we speak to Miss Cheerilee. We don't want to get in even more trouble." "What? That doesn't even make—" "Shh!"
