After the series of events that just transpired, the two girls once more set off around the school, keeping their eyes peeled for any sort of opening. When all hope seemed to be gone, that was when one of them finally spotted an opportunity.

"Aha! Look!" Rarity pointed at an open window located up ahead, that appeared to be a little bit high up.

"Great. Now, how do we get up?" Twilight wondered, staring up at the opening.

"We'll hoist one of us up, then one of us will pull the other through. Simple." Rarity stated matter-of-factly.

"Alright, who's gonna push up who first?"

"I'll push you up first. Then you'll pull me up." Rarity stated, getting into a kneeling position and holding her arms outwards. "Here, climb on."

"Okay, if you're sure with this." Twilight blushed a bit, before slowly stepping onto her friend's arms, then onto her shoulders.

"Whoa!" The sciencey girl rocked back and forth unsteadily, before placing her hands on the wall for balance.

"It's alright, I've got you." The fashionista below her assured, her own legs wobbling just slightly. "Just focus on getting through that window."

"O-okay." Twilight adjusted her glasses, her heart pounding in her chest as she reached up and grasped the windowsill. Using all the strength she could muster up, she hoisted herself up and into the window landing on the inside.

"Twilight?" Rarity called up, looking up at the window. "Are you alright, dearie?"

After a few moments of silence, she saw her stick her upper body out, reaching her arm towards her. "Grab on!"

The fashionista followed her order and clasped onto her hand tightly.

Twilight grunted and started to pull her up, quickly switching to using both arms. "Wow Rarity… you're a lot heavier than you look."

"Are you calling me fat?"

"What!? No, I didn't mean it like…." Twilight paused upon hearing her friend giggling, obviously not being serious. "Ha, ha, real funny." She said in a sarcastic tone, before using the rest of her effort to pull the girl up and through the window. Unfortunately, a certain part of the fashion girl's body was unwilling to cooperate.

Both of them stood quiet for a second, with Rarity stuck half way through the open window. The fashionista was the first to speak.

"This. Is. Not. Happening." She said dismally, her cheeks turning a rosy pink, while her other pair of cheeks hung outside the window, proudly displayed for whoever comes by and sees.

Twilight gulped nervously, of all the things to happen, this was something she was not prepared for.

"Oh my gosh! What are we supposed to do!? If somebody comes by and you're still stuck, they're going to get the mooning of the century! And worse, what if they decide to take pictures!? And then…." The panicking girl stopped herself short, seeing the unamused look on her friend's face.

"Not exactly helping." Rarity told her in a deadpan tone.

"Oops, sorry." Twilight breathed slowly in an attempt to cool her head off. "So, let's take it easy and think of some ideas."

"Well, we don't really have the luxury of time here." The fashionista reminded her, feeling a slight breeze brush along her bare tush, making her shiver.

"Right, right." Twilight responded absentmindedly, tapping her chin anxiously. "Ohh, what could we do? Maybe butter the sides? Oh, but there's nothing here to lather the sides with!" The spectacled girl panted heavily, before she felt a bead of sweat slowly trail down her face. Just like that, she got an idea.

"I've got it! Maybe you could use your sweat as a form of lubricant to free yourself."

Rarity quirked an eyebrow uncertain. However, she knew she didn't have any other options on the table at the moment.

"Alright, I'll try." The fashionista replied, and started struggling as hard as she could, trying her best to work up a sweat. After about a minute of constant struggling, she felt her hips slowly start to budge.

Twilight gasped, smiling widely. "Ooh, it's working! Keep it up!"

With newfound confidence, the fashionista grunted as she kept pushing herself more and more, feeling her backside slowly but surely make its way through the small window. After a few more minutes of struggling, she finally made it completely through, sending herself flying forwards.

"I've got you!" Twilight called out, catching her friend mere seconds before she landed face first on the floor.

"Phew, thank you Twilight." Rarity smiled gratefully, wiping some sweat from her forehead. She peeked behind her at her rear, which had a pink ring surrounding it.

"Oh dear, I hope that doesn't stay long." She said, wincing a little.

They both looked back at each other, then around the room they were in.

"Where are we?" The fashionista inquired, looking around and finding desks lined up against a wall.

"Looks like a classroom." Twilight responded back. "Should we turn the lights on?"

"After we shut all the windows in here." Rarity replied.

"Of course."

They both quickly went over to the windows and made sure each one was shut, and the blinds pulled down. Once that was taken care of, Twilight went over and flipped on the lights. The whole room was slowly illuminated as the fluorescent lights kicked on.

Seeing each other standing naked in the middle of a school classroom made the two girls involuntarily cover up their private bits. They both knew they were alone yet being in such a familiar place with nothing covering them made them feel strange. After a few seconds, they each slowly uncovered themselves again.

A few more minutes went by with no one uttering a word. However, they each knew what the other was thinking, as they both began to grin mischievously. The two girls let out little giggles of giddy excitement at the idea of being completely butt naked in their own school.

"I can't believe it. We're actually naked inside our own school." Twilight stated.

"And no one else is here but us." Rarity added.

The two of them felt their bodies tingle with enthusiasm, thinking of all the possible things they could do here. Just the ideas alone made both of them feel hot.

"Well then, shall we continue?" The fashionista insisted with a coy little grin, before opening the classroom door and stepping out into the empty hallway. With a quick flick of a switch, the hallway was illuminated just like the classroom.

Twilight followed her friend out into the now lit hall, feeling a shiver of excitement run down her spine. While the two of them stood out in the hallway, a barely noticeable chilly breeze brushed along both girls' lower halves, making their nether region's tingle with pleasure.

"So, what are we going to do first?" The nerd inquired with curiosity.

"Hmm…." The fashionista mused in thought, before a smirk curled on her lips. She went over to a row of lockers, and looked over each one, much to the puzzlement of her friend.

"Umm, what are you doing?" The spectacled girl asked in confusion, adding to the amusement of her fashion-centric friend.

After looking for a bit, Rarity found exactly what she was looking for. "So, this is your locker right here, correct?" She asked, pointing to a specific locker.

"Uh, yes?" Twilight replied, still uncertain on where her friend was heading with this.

Rarity's sly smirk only grew upon hearing the affirmation. "Good to know."

"Wait, why?" The nerdy girl wondered, watching as her friend stood right in front of her locker.

Rarity turned around so that she was facing Twilight, a naughty smirk on her face as she bent forwards a bit, before pressing her bare ass right against the locker's surface. A familiar chill ran up the fashionista's spine as her butt cheeks made contact with the cold metal, making her coo in delight.

"Hey!" Twilight protested with a red face. "Wha… what are you doing!?"

"Just leaving a little something behind for you." Rarity grinned as she slowly removed her rear from the locker, the flesh of her tush actually stuck to it a bit before she finally pulled it away. This had left a large butt imprint on Twilight's locker that made the purple skinned girl blush even redder.

"Oh… that's so perverted…" she muttered.

"So is what we're doing, darling." Rarity reminded.

"Yeah…" Twilight admitted.

"Tell you what, when we come across my locker, you can do the same to mine." Rarity offered.

"O-Ok." The sciencey girl nodded, comforted.

"Come now, there's still much fun to do." Rarity declared as she took Twilight's hand and guided her down the hallway, their bare feet slapping against the hard floor as they walked.

Twilight shivered. "The floor is so cold…" she remarked.

"Indeed." Rarity agreed before another thought came to mind. "Tell me dear, what do you think would happen if someone were to see us right now in our birthday suits?"

"Well… if it was a teacher or Principal Celestia we'd probably get suspended…" Twilight reasoned.

"And if it's just another girl? Another… shall we say… riff raff, like us, prowling the halls?" The fashionista added.

"She would probably think we were perv's… unless it was Rainbow Dash of course." Twilight pointed out.

"It if was Rainbow Dash she would no doubt still laugh at us." Rarity stated. "After all, we don't quite have an excuse for doing this."

"Right… I mean… here we are… totally naked and… walking around the hall…" Twilight slowly realized with fear.

"I know, isn't the thought of being spotted exciting!?" Rarity inquired, giddy.

"Well…. Maybe a little bit." The nerdy girl felt another chill rush through her body, but this time it left her with a tingly feeling. She slowly began to grin widely, giggling at the tingling sensation.

"See what I mean?" The fashionista said with a sly smirk.

"Yeah, I think I do."

"Excellent! Let's continue."

They both continued making their way down the quiet, empty hallway. The only noise heard was the sound of the two naked girls' feet slapping and peeling off from the cool tile floors. It almost felt a little eerie how quiet it was, given how loud the school halls could get during the day. It only added to both of their excitement as they casually streaked through the halls.

Eventually, the two girls walked by the principal's office. Twilight came to a stop and felt her heart skip a beat, standing dead still right in front of Principal's Celestia's empty office. Even though no one was in there, the mere idea of standing naked right in full view of where Celestia would've been sitting during a regular school day, made goosebumps appear all over the spectacled girl's bare skin.

"That's…. That's…." The nerd stammered.

"The Principal's Office." Rarity finished, her own body shivering a little, with her butt cheeks clenching instinctively. On any occasion, if the principal actually saw them both standing right in front of her office in their birthday suits, they would've been suspended at the very least.

However, she wasn't there, and the office was empty, with two streaking girls standing by it. Rarity felt a coy grin cross her lips, an absolutely nasty thought invading her mind.

"Ooh, Twilight I've got it!" The eager fashionista grabbed a hold of her friend, bringing her closer. "Let's go over and moon the principal's office." She giggled rather impishly while Twilight's face flushed a deep shade of red.

"Wait, you're not saying…."

"Yes, let's go and press our derrieres up against the glass doors." Rarity smirked devilishly, as Twilight's eyes widened.

"What!? Are you crazy!? This is Celestia's office! How do you think she'll react when she finds two…." The nerd paused and gulped worriedly.

"Do you really think she's going to know who did this? If anything, her first suspicions will be that Rainbow and Pinkie did this. After all, she already knows those two are quite the pranksters." Rarity explained to a sweating Twilight.

"But…. But…."

"You said you agreed to have a little fun right?" The fashion centric girl asked with a mischievous grin.

"Well, yeah, but…."

"Ah! No more buts! Speaking of, I'm going to be pressing this one up against that door." Rarity stated with a smirk, giving her bare ass a quick smack. The fat on her glutes wobbled wildly, distracting Twilight for a brief moment and making her stare. The fashionista giggled at her friend's face before she went ahead, strutting boldly over to the glass doors, her lovely hips swaying in exaggerated movements as she did so.

She turns to her friend again. "By the way, do you think you could give me a boost so my booty can reach the window of the door?"

"Uh… I don't know…" Twilight said, unsure and nervous.

"I'll give you a nice butt massage after!" Rarity offered.

"You know butt massages?" Twilight inquired, surprised.

"You're not the only one who does research." Rarity beamed in a cute manner.

The sciencey girl tapped her fingers together while in thought, running the idea through her mind a couple times before finally reaching to a conclusion. She let out an exasperated sigh, nodding over to her friend.

"Alright, I'll do it."

"Excellent!" The fashionista clapped her hands, giggling giddily as her nervous friend walked over to help her up.

Once she was by the door, Twilight rested on her knees and held out her arms, similar to how her friend hoisted her up through the window earlier.

Rarity carefully stepped up onto the spectacled girl's hands, bracing her own hands against the door for support. She peeked through the square window into the office, still as empty as before.

As she looked, Twilight's face was inches away from the fashionista's large, jiggly posterior. Every individual ripple and movement across her friend's bare butt cheeks went noticed by the nerdy girl, which only made her face turn a bright shade of red.

"Hmm, I wonder if this little window is even big enough for my lovely derriere." Rarity spoke, giggling a little and giving her rear a quick wiggle, adding to Twilight's blush. "Well, I suppose it's worth a shot."

She quickly turned, causing Twilight some slight pain as she stepped on her hands to do so, before pressing her bottom against the window of the door, covering it completely. What was really surprising was that the extra flesh on her tush went over the edges of the window, which would no doubt leave an imprint on the skin of her buttocks later on.

Rarity giggled. "Nope, I guess not!"

"Hurry! I think I hear someone coming!" Twilight said, hushed.

"It's just your imagination darling, there's nobody here but us." Rarity pointed out as she continued to wipe the door with her rear. Audible squeaking and creaking sounds were heard as the fashionista shifted her buttocks against the small window, trying her best to squish both her butt cheeks flat up against the glass. If someone were to be sitting inside the office, they would see nothing, except for two large, soft marshmallows flattened on the glass, covering up the entire small window space.

Twilight gulped nervously as her eyes darted left and right down the empty halls. Meanwhile, Rarity snickered naughtily as she made sure to give the principal's office a full moon.

Eventually, the sounds Twilight were hearing started to get louder, though the nerdy girl couldn't tell if they were real or in her mind. Still it made her paranoid and very much so.

"Ok Rarity, that's enough, we have to hide!" Twilight told her, hushed.

"Hide? Whatever do you…" Rarity began before Twilight lowered back down, shoulder slammed the door to the office open and grabbed Rarity as she pulled her inside and closed the door behind them.

"Twilight! What has gotten into…!" Rarity started to exclaim before Twilight thought quickly and pressed her lips against Rarity's, in an effort to shut her up, stunning the fashionista and causing her eyes to widen as she let out a muffled cry.

Sci-Twi lowered them both down until they are sitting below the imprinted window, her back against the door as she and Rarity continued to make out, something Rarity gratefully returned.

Slowly but surely, as it continued Twilight moved her hand over to Rarity's bum, but before she could squeeze it, Rarity ended the kiss.

"Before we go any further, how about I give you that butt massage now?" The purpled haired girl offered. "In return, you have to pleasure me through my rump."

It didn't take nearly as long for the spectacled girl to come up with an answer, quickly nodding her head.

"Alright, deal." She spoke in a quieter tone, a sly smirk growing on her lips.

"Great! Lay down on your stomach first." The beautiful girl instructed.

After Rarity got up and stepped to the side, Twilight did as she was told and laid down flat on her belly right next to the Principal's desk. Rarity came over and kneeled down beside her, eyeing her plump rump like a piece of juicy meat.

"Um, Rarity?" Twilight asked, wiggling her rear to bring her friend back down to Earth.

"Oh, right! Sorry about that." A rosy tint invaded the fashionista's cheeks.

Rarity slowly places her hands at the top of Twilight's buttocks and fanned them up and down, following its natural roundness. As she continued to rub around the sides and back around, in a circular motion Rarity felt a great rush of pleasure as she kneaded and squeezed the flesh of Twilight's bum, it was if she was squeezing two exercise balls.

Twilight also felt greatly aroused by the pleasure she was feeling from having another person touch her bottom the way Rarity was. She let out a long moan as Rarity pulled up the sides of her tush and kneaded the fleshy areas on top.

Both of them moaned even louder as Rarity moved her hands down Twilight's lower back, cups both her butt cheeks and moves them around in a circle before pulling them up and letting them go, the two cheeks jiggled like jello.

Twilight let out a little coo of satisfaction, enjoying the sensation of her friend grabbing and letting go of her twin purple globes. A wide grin spread out across her face, nothing she had ever done before matched up to the sensual feelings she was experiencing now.

Rarity continued to gently press and knead the flesh of her friend's glutes, similar to how a professional baker kneaded fresh dough. She gave the twin cheeks just a tiny squeeze between her fingers, gaining a surprised gasp from her friend, followed by another moan.

As she dug her fingers into the flesh of her sciencey friend's butt she also dug into it with her elbows, making Twilight moan and cry out even louder while she kicked her feet. Once she had settled down, Rarity moved her face closer to Twilight's tush and gave it a nice little peck.

The spectacled girl felt another blush coming on, upon feeling her friend give her rear end a quick little kiss. It was an odd feeling, that she strangely enjoyed.

Rarity smirked and planted her lips onto the soft flesh once again, keeping her mouth there for a while longer, tasting her friend's rump. After what felt like a long time, she removed her lips from the nerdy girl's tush, making an audible wet smack as she did so.

Feeling daring, Rarity also gave Twilight's bum a little bite, causing to her react more than before.

"Ow!" The glasses wearing girl exclaimed in pain.

Rarity removed her mouth from the cheek, which now had a faint bite mark on it, with an embarrassed face. "Oops! Sorry, suppose I got carried away…" she apologized.

"Yeah… a little…" Twilight confirmed as she turned over and sat up a little before Rarity got on all fours and moved closer to her, making Twilight lean back, uncomfortably.

"We could still go further in a way that's more… pleasurable." Rarity offered, whispering into Twilight's ear seductively.

Twilight made an educated guess as to what she was implying and gulped. "You… swing that way…?" she inquired, slowly. Despite having initiated the kiss earlier, the whole subject on same gender love made her feel uneasy to a degree though she would never scold someone for it.

Rarity simply giggled at her friend's confusion. "Oh, I noticed how hot and bothered you got as soon as I told you and the rest that I mooned that one store." She smirked as she saw a familiar rosy tint appeared on the nerdy girl's cheeks. "Ever since I told you that information, you've been a lot more curious about other naughty acts I've pulled. Not to mention, you've been staring at my fanny a lot more as of recently."

"I… well… who wouldn't? Right?" Twilight remarked with a nervous grin.

"True… but still, a bi-curious lady such as myself can't help but do the same." Rarity admitted.

"I'm… aware but…" Twilight started to say before Rarity put a finger on her mouth and shushed her.

"Just flow with it, darling." The fashionista said, soothingly before taking her finger off Twilight's mouth and kissing her again.

Rather than protesting the sudden kiss, Twilight felt her eyes start to close, returning the kiss back in full force. She even felt her hands start to move over behind her friend's back and grab her hindquarters like she originally intended, before quickly stopping them. After all, it's rude to just reach behind and grab your friend's bottom, wasn't it?

After about a minute, Rarity pulled her lips back, her eyelids fluttered suggestively. Twilight was blushing intensely at what she almost did, not sure whether or not she should tell her.

"So, how was that?" Rarity asked, with a sly smirk still on her lips.

"N-Not bad…" Twilight stuttered.

"I should imagine so, since you were the one who kissed me first." Rarity reminded.

Sci-Twi blushed. "R-Right…"

"And now… for my own 'first'..." The purple haired girl declared, slowly.

Rarity quickly grabbed onto Twilight's breast and squeezed it like an exercise ball, making her friend squeak while she rubs it all over. Twilight squealed louder and louder as Rarity caressed her boobs up and down and side to side as if it was uncooked dough.

This made Twilight pant as her nipples became erect, which Rarity felt, grabbed, twisted left and right and pulled on it before lowering her head and sucking it, all of which made Twilight cry out over and over again before she eventually turn and fall right over. Her back flesh landed on the cold floor, which sent a shiver up and down her spine while Rarity landed right on top of her breasts, which she rubbed her face against over and over.

The fashionista let out a muffled moan while her face was buried in her friend's boobs, sending a shudder of excitement rushing through the spectacled girl's entire body, and making her let out a little yelp.

Rarity smirked as she kept one hand on top of Twilight's other breast and squeezed it tight then slowly lowered the other hand all the way down her chest and stomach. She caressed her crotch before she reached her vagina. Rarity then stuck two fingers into her slick folds. She shivered as she felt the wetness of Sci-Twi's pussy and reveled in the squishiness she felt as she went further inside but stopped when Twilight gasped and cried out.

"Oh! So sorry! Did that hurt?" The white skinned girl asked, concerned.

Twilight panted feverishly before raising her head and smiling at Rarity. "No… it's ok… keep doing that…"

"Very well." The sapphire eyed beauty said before she moved her fingers in and out of Twilight. She gained more and more depth as she continued, making it start to leak juices. "How's this?"

Twilight could only respond with a pleasure filled moan. As Rarity began to push her fingers against Twilight's folds with more force, the nerdy girl started to squirm and moan underneath her touch, her legs writhed under the attention. The stimulation in her body grew even more as she felt Rarity play with her pussy for a bit before going straight in again.

Twilight cried out from the satisfaction shooting up through her body, like a rush of adrenaline and lust. She quickly covered her own mouth afterwards, afraid someone could've actually heard her from the hallway.

This didn't distract Rarity from sliding her now slick fingers in and out of the sciencey girl's wet folds, each time she made a movement with her fingers, she felt her friend tremble and gasp in pleasure.

Eventually her hand, as if it was moving on its own, reached out and hovered in front of her friend's winking clitoris. She seemed hesitant to do anything until Rarity spoke up.

"It's alright dear, go right ahead." Rarity encouraged before letting out an excited gasp as Twilight touched her pussy and cried out to the heavens as Twilight pushed her fingers deeper inside her. She shivered a bit more before lowering her head into Twilight's breasts again, concerning her.

"Are you ok? You're so tight and hot down there…" Twilight remarked.

Rarity removed her face from the nerd's breasts, a wide grin evident on her face, as well as a bright red blush. "I'm fine. I-it's incredible. Please, do continue."

"Please… don't strain yourself…"

"It's ok…"

"But…"

Rarity smiled at her sweetly. ""It's ok, it's just a little pain… I can take it…" she assured her. "Now come on… make me feel good…"

Twilight was a little surprised but smiled. "Alright," she nodded, before Rarity moved her head forward a bit and they kissed again. Their tongue's started swirling around each other again, mixing their saliva while their docked breasts push against each other and their fingers begin moving in sync as they both thrust their fingers into each other over and over again, making them breath heavily.

The purple skinned girl felt her free hand start to move again, but this time she didn't stop. She reached behind her friend and grabbed a fistful of her friend's supple ass, squeezing it tightly in her grasp. Rarity gasped with pleasure feeling this and responded by doing the same to her friend's bosom, as they both squeezed on each other's naughty bits and made love at a fast pace, they soon reached their climax at the same time.

They screamed at the top of their lungs as their juices either squirted or poured out, depending on who it was. Both shook like crazy as pleasure generated by their individual orgasms washed over their sweaty bodies. When it finally ended they stared into each other's eyes and then started making out once again. Not long after, everything went dark as the two girls panted and basked in the afterglow of their little session.
