Chapter 1: Keeping it on the low

"Did she ask to see you too, darling?" Rarity asked, coming up beside Rainbow Dash as they headed down the hall to Twilight Sparkle's office at the School of Friendship.

"Yeah, I wonder what it is this time." Rainbow Dash rolled her eyes.

"Shh." Rarity hushed Rainbow Dash as they got close to the door to Twilight's office. They could hear Twilight's muffled whimpering and moaning through the door. Rarities horn glowed as she magically pushed the door open just a crack and the two mares stared through across the office. They could see Twilight slouched back awkwardly on a chair behind her desk. Her mane was in slight disarray and her head was pitched even further back as she panted and moaned quietly. Her front hooves were held down out of sight beneath the desk.

"Oh my gosh is she-" Rainbow Dash snickered, interrupted by Rarity's hoof in her face.

"Um. Twilight Dear?" Rarity called through the door.

"Come in!" Twilight's voice cracked as she laughed nervously. She blushed red and she snapped back into a more natural posture.

"You wanted to see us both?" Rainbow Dash quizzed as the two entered Twilight's Office.

"Well you two did such a great job on that mystery I sent you two on." Twilight began. Rarity and Rainbow Dash could see that she was fussing with her front hooves beneath the desk.

"You mean that fake mystery?" Rarity rolled her eyes indignantly.

"No!" Twilight whispered loudly as she looked beneath the desk. "I mean yes. I'm sorry if my methods were a little unconventional." She laughed nervously as she continued fussing with her front hooves.

Out of Rarity and Rainbow Dash's sight Starlight Glimmer hid, prone, beneath the desk. She flashed a devilish, seductive, grin up at Twilight when she quickly glanced below to tell Starlight off. Starlight was trying to reach a front hoof past Twilight's midriff but Twilight kept fighting her off with her front hooves.

"It was totally awesome and fun... but uncool to deceive us like that!" Rainbow Dash lectured.

"Though we did make a fabulous team!" Rarity interjected as she reached a hoof over to Rainbow Dash. Rainbow Dash clopped her hoof against Rarity's and the two held their hooves together for a moment.

"Well that's the thing. Now the School of Friendship has- Unh!" Twilight interrupted herself with a moan. Beneath the desk Starlight's horn glowed as she used her magic to directly stimulate Twilight's clitoris. "a real mmm... mystery" she slouched back up onto the chair behind her in surrender.

"Are you okay, darling?" Rarity asked with concern.

Starlight crept closer and took advantage of Twilight's posture. She pressed her muzzle between Twilight's hind legs and her tongue went straight for Twilight's clit.

"Oh!" Twilight moaned. "I'm... Fine" she panted. "It's a little hot in here isn't it?" She reached below the desk with her front hooves and gently stroked Starlight's mane.

"Actually I'm a little chilly" Rainbow Dash rolled her eyes as she replied in a skeptical tone.

Starlight's head bobbed as she held her tongue stiff and worked it back and forth over Twilight's clit. Twilight struggled to keep a straight face as she panted and moaned.

"So-Ooh" Twilight's eyes rolled back as a look of ecstasy washed over her face. "I was thinking you two girls could mmm maybe investigate for me."

"Well of course, darling, anything for a friend, right Rainbow Dash?" Rarity looked over at Rainbow Dash.

"Right!" Rainbow Dash confirmed.

As Starlight continued to lap at Twilight's clit her horn started to glow. Magical force parted Twilight's vulva and a glowing, phallic concentration of magical force began to penetrate Twilight's pussy, in and out, in rhythm with her tongue. Rainbow Dash and Rarity flashed a very confused look at Twilight as she panted and moaned.

"Are you sure you're alright darling? We could run and grab the nurse for y-"

"Unh! I'm fine!" Twilight insisted with a moan. Her body quivered with pleasure as she stroked Starlight's mane in rhythm with the onslaught of pleasure.

"Why don't you explain this mystery to us..." Rainbow Dash rolled her eyes at Twilight.

Twilight simply nodded in reply and breathed hard. She began bucking her hips in rhythm as Starlight increased her pace and penetrated deeper with the magical phallus. Twilight brought one of her front hooves up and bracing herself against the desk with it. "mmm! There's been reports.. Ohh!... of strange... mmm!... activity..." Twilight could barely get the words out coherently.

"There's some strange activity in here." Rainbow Dash rolled her eyes again.

Twilight let out a gasp as she reached orgasm. Her muscles all tensed and shuttered. Starlight scuttled back as Twilight slumped forward against the desk. Twilight panted as she caught her breath.

"Darling?" Rarity leaned forward and prodded at Twilight's face. She wore an almost demented look of satisfaction.

"Hehe! yeah..." Twilight chuckled nervously. "So there's been some reports of strange activity around the campus at night. Plus students and faculty have been acting...unusual." Twilight explained as she perked back up into her usual posture.

"Unusual, how?" Rarity inquired.

"Unusually, uh, amorous. We're worried that it might be some kind of magical curse." Twilight blushed and grinned nervously as she explained.

"I'll say" Rainbow Dash rolled her eyes at Twilight. "Wait, we?" She quizzed, finding the choice of words odd.

"And since you two have been away on a friendship mission all week it seems you haven't been afflicted yet." Twilight looked over at the duo.

"We're on the case!" Rarity piped up. Twilight nodded in reply.

The two trotted out of the room and closed the door behind them. Starlight Glimmer emerged from beneath the desk. Her and Twilight kissed passionately.

"I might have to hold you here late on bad behavior." Twilight smirked smugly at Starlight.

"I guess some ponies never learn." Starlight said seductively, gesturing at herself and winking an eye.

Chapter 2: A secret escape

"Curse or no curse that was certainly rude!" Rarity huffed in disbelief as she walked away from the office with Rainbow Dash.

"Yeah, playing with yourself like that in front of other ponies, totally uncool." Rainbow Dash agreed.

"She looks rather suspicious..." Rarity whispered calmly to Rainbow Dash and pointed to a mare, completely obscured in a cloak down the hall.

The cloaked mare noticed the attention and quickly bolted down the hall.

"Wait!" Rainbow Dash shouted as she jumped up and quickly flew toward the mare in a streak of rainbow. Rarity followed in a gallop but couldn't keep up as Rainbow Dash chased the mare around a corner. Rarity rounded the corner to find Rainbow Dash looking around confused, catching her breath.

"Where did she go!?" Rarity asked, confused.

"This is impossible. She must have escaped through a secret passage." Rainbow Dash sighed.

"Well why don't you go look around for this passage and I'll start questioning students." Rarity suggested. Rainbow Dash nodded in agreement.

As the 'clip clop' of Rarities hoof-steps faded into the distance Rainbow Dash looked around the hallway. She burst through the first door she saw and found Applejack in front of a class.

"Uh... Did anycreature see a mysterious cloaked figure come through here?" She asked.

"What the hay are you doing interrupting my class? No, we didn't!" Applejack sneered back.

Rainbow Dash closed the door and turned to a room across the hall. She stepped in and closed the door behind her. It was a janitor's supply room.

"Oh, Hi, Rainbow Dash!" Spike greeted her as she walked in.

"You didn't happen to see a spooky looking pony in a cloak come through here and go through some kind of secret passage did you?" Rainbow Dash raised her hoof to her chin.

"It's my fault! I admit it!" Spike started crying.

"Wait, what?" Rainbow Dash was confused. She went over to spike and patted him on the shoulder comfortingly.

"A few nights ago Twilight asked me to guard the secret passage to the relic room and I fell asleep on the job and now the Amory Stone is missing and that's when all the weirdness started." He sobbed. "I replaced it with a look-alike so Twilight wouldn't notice." He rubbed the tears from his eyes and sniffled.

"Amory Stone?" Rainbow Dash asked.

"It's an ancient magical Hippogriff relic, that was used in their ancient mating rituals." Spike sniffled again.

"You're going to have to tell Twilight eventually." Rainbow Dash sighed as she handed him a tissue. Spike took the tissue and blew his nose.

"I don't want Twilight to think I'm a bad friend. I'll do anything I can to help just please don't tell-" Spike pleaded.

"Anything?" Rainbow Dash interrupted. She felt a an odd sensation, like a jolt of electricity, in her head. She turned away from Spike and assumed a stretching crouched forward posture with her plot up towards Spike.

"Rainbow Dash, I-" Spike felt the 'zap' too and walked up behind Rainbow Dash. He grasped his claws into her rump. His dragon cock throbbed and hardened as it emerged from it's scaly hiding place. Not quite as long as a stallions would be but it still had comparable girth. "I've never-" he stammered.

"Just fuck me!" Rainbow Dash commanded.

Spike shook nervously as he reached down and guided his throbbing dragon cock into Rainbow Dash's pussy. He put his claws back up on her rump and dug in as he started thrusting in and out of her.

"It's so hot!" Rainbow Dash pitched her head back and let out an uncanny moan. She had never been fucked by a dragon and couldn't anticipate how much hotter the core of his body was. Not so hot that it injured her but just hot enough to deliver a sensation of pain and danger.

"S-sorry." Spike stammered as he slowed his thrusts.

"No! Don't stop. I need it!" Rainbow Dash pleaded as her eyes teared up slightly.

Spike thrusted faster and deeper with the encouragement. He started breathing heavily. He could already feel his climax approaching.

"Unh! Please don't stop!" Rainbow Dash begged and moaned.

Spike tried to slow down to prolong the moment but the change of pace just brought his climax closer. His body shuttered and he let out a whimper as he came inside Rainbow Dash. His cum was even hotter than his cock and caused Rainbow Dash to yelp in pain. He slumped to his knees with a look of shame as his cock softened.

"I'm sorry. I've never-" He wimpered.

"Oh, you're a virgin?" Rainbow Dash turned around to comfront him. She gave him a hug and patted him on the back.

"Well I was... but I really like-" Spike sobbed

"Rarity?" Rainbow Dash interrupted. "It will be our little secret." She whispered into his ear. Her marehood still pulsed and ached with anticipation.

Rainbow Dash gently pushed spike down onto his back as she traced her mouth from his ear, down his neck, down his chest, down his midriff. She crouched down on all fours as she worked her way down his body. His cock began to harden and throb again as her mouth got closer and she stroked one of her front hooves against it. Spike moaned as she opened her mouth wide and his throbbing dragon cock disappeared inside. She worked her mouth up and down and with each breath visible snakes of condensation danced off of her saliva as it was heated by his hot shaft.

"Oh, Rainbow-"He moaned.

Rainbow Dash pulled her mouth away and climbed up onto his cock, guiding it in to her pussy with a front hoof. As she awkwardly arched her body to accept his member she leaned down to Spike's ear. "Close your eyes... picture Rarity." She whispered softly.

"Mmm. Oh, Rarity!" Spike corrected himself as he closed his eyes and imagined Rarity there instead of Rainbow Dash.

Rainbow Dash moaned and pitched her head back as she rhythmic bucked her hind legs, lifting her body on and off of his piping hot shaft. The contrasting feeling of pleasure from his hard cock and the searing grasp of the heat only served to intensify Rainbow Dash's pleasure. Her pussy contracted tightly around his cock as she reached climax, bringing him to climax again along with her.

"Oh, Rarity." Spike whimpered one last time before opening his eyes as Rainbow Dash slumped down beside him and the two embraced each other in the middle of the stone floor.

"Not bad... for a newbie." Rainbow Dash panted teasingly. "Rarity is going to be a lucky mare one day." She kissed Spike on the cheek as she gently massaged one of her front hooves over his chest and stomach.

"Really? You think?" Spike's face lit up with joy at the compliment. Rainbow Dash simply nodded in reply. "You don't think Rarity will be jealous?...of this?" A tone of insecurity returned to his voice.

"It's not your fault she didn't know what she was missing out on." Rainbow Dash teased. "Besides we were under the influence of some spooky magical relic. I really have to get back to my investigation." She sighed.

"Wait! Before you go there's something I need to tell you about the Amory Stone." Spike sighed back.

Chapter 3. Keeping it professional

"Classes are in right now so any student who isn't in class is a good place to start the interrogations." Rarity thought to herself as she trotted through the empty hallways looking around for her first suspect. "A unicorn would be the obvious place to start since we might be dealing with a magical curse." Her thoughts continued as she peered through a classroom window at a young unicorn. "Though arcane relics do exist that can give a non-unicorn magical powers." She looked over at the rest of the diversity of students in the class.

Rarity scanned the hallway ahead of her and saw a pair of shadows scampering around a corner up ahead. "Perhaps the best place to start would be free of assumptions. To simply look for somepony, or somecreature out of place." She narrated to herself as she quietly trotted around the corner in pursuit of the wandering students. She saw the doors to the school library swinging closed just down the hallway.

"I entered the library. It was just me and the librarian. Though the conference room in the far corner had it's blinds drawn and the door closed. They were normally kept open when not in use-"

"Shh" The Librarian pony interrupted her.

"Oh, Sorry. I was talking out loud that time wasn't I?" Rarity blushed.

Rarity quietly crept to the door of the conference room and gently tested the handle. It was locked. She turned her ear to the door and could hear faint murmuring but couldn't make out what was being said. Her horn glowed as she levitated a hairpin out of her mane and into the key hole of the door. After some fussing the lock gave way with an audible click and she burst in.

"Aha! What are you-" Rarity frozen in shock. Sandbar and Gallus slouched back in two adjacent chairs. Gallus had a claw wrapped around Sandbar's errect cock and they were staring at a magazine on the desk.

"Ah!" They both shouted in surprise. They jumped up and bolted for the door; Rarity kicked it shut with one of her hind legs before they could escape.

"Not so fast, boys." She slowly walked over to the desk and observed the magazine. "Mares in Socks." She read out loud off the cover as she flipped it closed. She flipped it back open to the page they were on; a foldout of a yellow mare on her back, in pink and blue striped socks, masturbating. "So this filth is what you're skipping classes for!" Rarity huffed as she motioned for the boys to sit back down in their seats, they complied.

"What do you boys know of this 'amorous' curse?'" She stared disapprovingly toward Sandbar.

"N-nothing, miss rarity." Sandbar whimpered.

"What exactly have we done wrong?" Gallus rolled his eyes. "We both have a free period right now. We're both old enough to buy this magazine."

"In the school library!?" Rarity objected. She walked over to Sandbar and trailed one of her front hooves down his nose to his chest. "Barely a stallion." She teased.

Gallus perked up and cocked his head sideways as he observed the odd shift in Rarity's behavior. Sandbar still trembled nervously but his cock grew hard again as Rarity continued trailing her hoof down his midriff as he slouched back, offering her no resistance. Gallus's feline-like cock began to harden and emerge out of it's sheath as he watched Rarity start to lean down toward Sandbar's hard cock. He grinned as he got up and prepared to mount Rarity from behind.

"Sweet Celestia! What has come over me!?" She suddenly protested. She came to her senses and backed away. Sandbar and Gallus let out a frustrated sigh in unison.

"I'm so sorry, boys. Handsome young stallions both, but two students and a teacher? This is highly improper." She sighed as she hung her head in shame.

"It's okay, miss Rarity." Gallus placed a claw sympathetically on Rarity's back. "Everything has been a little weird around here lately." He explained.

"Just what were you two boys up to anyways?" She interrogated.

"Gallus and I made a bet!" Sandbar piped up excited.

"He won." Gallus rolled his eyes. "I was so sure I would win I wagered 'whatever he wanted'". He sighed.

"Well what did he ask for?" Rarity asked with a concerned voice.

"Some bomb-ass head!" Sandbar boasted.

"Well you don't have to do anything you don't want to." Rarity smiled over to Gallus.

"Well I never said I didn't want to. We've both had a dry spell with the ladies so I think it would be very generous of me." Gallus explained.

"Well then I insist, you carry on!" Rarity gestured over to Sandbar.

"Uh... Miss rarity?" Sandbar looked over at Rarity from his chair confused, but strangely aroused, his cock was already rock hard and ready to go again.

"Well how could I possibly interrupt a genuine act of generosity like this?" Rarity pulled up a chair to a good vantage point of the action and slouched back in it.

"With you watching?" Gallus scratched the back of his head but then scooted down on the floor in front of Sandbar's chair

"For research, darling." She insisted.

Gallus wrapped a claw around Sandbar's cock and began pumping it up and down over the shaft as he leaned in and playfully flicked and swirled his tongue against the tip. Rarity reached down with one of her front hooves and began stroking it over her clit in circles, she and Sandbar both moaned softly.

"Mmm. Don't be shy, darling." Rarity moaned.

Gallus stretched his beak open wide to take in Sandbar's cock. He started bobbing his head up and down. Rarity stroked herself at an increasing pace and her breathing became more labored. Sandbar pitched his head back and whimpered with pleasure. Sandbar reached down and forced Gallus's head down, stuffing himself further into his throat.

"Mmm. Yeah that's it, darling." Rarity cheered him on. She began to buck her hips to the ryhtmic stroking of her hoof as she moaned louder and more frequently.

Gallus gagged and pulled himself free for a breath of air. His saliva glistened all over Sandbar's cock. As he caught his breath he stroked Sandbar's cock with his claw, the sloppy sound of the saliva spreading around under his grip further aroused Rarity; she let out a moan and began to shutter as she reached climax. The sight of Rarity moaning and squirming got to Sandbar and he gasped as he climaxed, shooting his cum onto Gallus's face. Gallus blushed.

"Here you go, darling." Rarity levitated a tissue over to Gallus. "Well I'm sure you two have plenty to talk about in private so I shall be on my way." Gallus and Sandbar both blushed red as Rarity slipped out of the room and closed the door behind herself.

Rarity levitated a piece of paper up to her face. Sometime in the commotion she had managed to sneak it out of the dirty magazine, it was being used to mark the page with their foldout. "Campus book store. 2 AM. Ocellus+Silverstream XOXO" Rarity read out and grinned slyly. "Never underestimate my feminine wiles." She snickered to herself proudly.

Chapter 4: Blowing your cover

"Did you catch that suspicious pony?" Rarity asked Rainbow Dash as they met back up in the hall.

"No but I found out an ancient Hippogriff relic known as the Amory Stone might be involved. Also that this school sure does have a lot of secret passages." Rainbow Dash explained as the two walked down the hall.

"That sounds more like your line of investigation, Darling" Rarity rolled her eyes. "I managed to secure a lead of my own." Rarity showed the purloined note to Rainbow Dash.

"Maybe there's a secret passage in the book store!" Rainbow Dash blurted.

The duo made their way to the campus book store.

"Classes would be out soon so we would only have a little bit of time to look for clues before the hoofsteps of the students would destroy any evidence." Rarity thought to herself. "Just outside the book store I saw what appeared to be a fleck of paper confetti on the ground." Rarity picked up the fleck of confetti and stared at it intently.

"What are you doing? You haven't said a word since we got here!" Rainbow Dash complained.

"I'm investigating!" Rarity belted back indignantly as she cocked her head up. Rainbow Dash just replied with a roll of her eyes.

Rainbow Dash followed Rarity into the book store as she followed a vague trail of the paper confetti to the 'little fillies room'. Rarity looked over to Rainbow Dash and then gently tested the handle. It was locked. A little red insert below the lock indicated that it was occupied.

"I guess we wait." Rarity sighed. The school bell sounded, followed by the sound of rabble as students started filing into the halls.

"Why dont' we take a break and come back tonight?" Rainbow Dash suggested.

"Good idea, Darling. We'll show up before 2 AM and catch the students off guard." Rarity agreed.

The duo quietly stalked their way back to the book store through the campus halls later that night. As they approached they could see that the security shutter of the book store was raised just enough for a pony to crawl under. They both walked up at the same time and peaked under it. There was only pale lantern light lighting the interior but they could see that there was a large line of male students lined up at the stallions washroom but none at the little fillies room adjacent to it. A small dividing wall created a few hoof-steps of privacy between the two washrooms.

"Do you think we can sneak there without being seen?" Rarity whispered.

"Piece of cake." Rainbow Dash whispered back. She hovered over Rarity and held her front hooves around Rarity. In a flash she darted, Rarity in tow, behind the dividing wall and the two mares quickly ducked into the washroom and quietly closed the door.

Rarity's horn glowed and lit up the room. She could see a confetti trail leading toward the far wall behind the toilet where it abruptly ended. She probed a hoof along the wall and felt a slight draft.

"I do believe secret passages are your forte, darling." Rarity smiled at Rainbow Dash.

Rainbow Dash began feeling around the wall for anything out of place. Rarity checked herself out doing 'detective' poses in the mirror above the sink. The door burst open unexpectedly and Silverstream and Ocellus sauntered in. Both duos froze up and gasped when they noticed each other.

"m-miss Rarity? m-miss rainbow Dash?" Ocellus stammered.

"Ladies! I don't know what you two are up to sneaking around so late but get back to your dorms now! We'll talk about this in the morning." Rarity lectured under her breath.

"But we're supposed-" Silverstream piped up.

"Do you want to get expelled?" Rarity threatened. Ocellus and Silverstream hung their heads and nodded and then strolled off.

Rainbow Dash went back to feeling around for a way to open the secret passage.

"Um, Darling?" Rarity called to Rainbow Dash, directing her attention to the wall leading to the adjacent stallion's room. They hadn't noticed on their way in but there was a hole in the wall leading between the two rooms, and an eager, throbbing, black and white, stallion cock was now sticking through.

"Oh my gosh, it's a gloryhole!" Rainbow Dash giggled.

"A gloryhole?" Rarity raised an eyebrow.

Rainbow Dash whispered into Rarity's ear.

"Well, I never! That is just so filthy and unladylike." She huffed.

Rainbow Dash reached a hoof over and started stroking the cock and holding it towards Rarity's shocked face. "Well you have to do something! You sent the girls away and they are expecting somepony to be here!" She urged. "Otherwise our cover will be blown."

"Why me?" Rarity whined.

"Because I have to keep looking for a way to open the passage!" Rainbow Dash rolled her eyes.

Rarity reluctantly cupped her front hooves on either side of the cock and started stroking up and down the shaft. "But this is one of our students! This is absolutely improper!" She protested.

"It could be anypony, that's what the wall is for." Rainbow Dash rolled her eyes at Rarity as she placed a hoof on the back of Rarity's head and pushed her face closer to the cock.

Rarity whimpered as she slowly worked her mouth around the tip of the mystery stallion's cock. She started bobbing her head, sliding it in and out of her mouth. Rainbow Dash gave her an encouraging pat on the back and returned to her task of examining the wall.

After a while Rarity found herself strangely aroused at the whole affair. She reached one of her front hooves down and started stimulating herself as she continued sliding her mouth up and down the cock with escalating vigor and enthusiasm. The cock stuffed in her face muffled her moans into "mmm"s and she could tell the young stallion on the other side was pleased by the humming as his muffled moaning and grunting could be heard through the flimsy wall. Rarity froze in confusion as she heard him knocking his hoof against the other side of the wall.

"Careful! That means he's going to-" Rainbow Dash tried to warn.

"Ulp!" Rarity sounded as her cheeks ballooned outward. The cock softened and retreated back to the other side of the wall. She looked over at Rainbow Dash and opened her mouth wide, showing off the load of cum in her mouth...some of it dripped off of her tongue and onto the floor. She then closed her mouth and swallowed the load down.

"You were totally awesome!" Rainbow Dash beamed proudly.

"Well that wasn't so bad." Rarity sighed.

"Well you're not done yet. Don't forget the big lineup!" Rainbow Dash pointed Rarity's attention back to the hole in the wall. This time a semi-flaccid dark blue cock came through the wall.

Rarity sighed and then went back to her 'duty'. The cock quickly stiffened in her warm, wet mouth. As the time dragged on Rarity made a game of it; figuring out which cock might belong to which student based on it's color.

Finally a familiar green cock came through the wall. Rarity knew it was Sandbar's. Rainbow Dash reached over and started stroking it with one of her front hooves while pointing to the, now open, secret passageway with the other.

"Good work, Darling." Rarity smiled.

Rainbow Dash playfully lashed her tongue against the head of Sandbar's cock. The two mares flashed each other a grin and gave each other a quick kiss on the mouth.

"We got this together!" They nodded approvingly as they spoke in unison.

The duo gently kissed their way up opposite sides of Sandbar's cock and met each other's face at the tip and kissed each other passionately. Rainbow Dash pushed Rarity's head down and Sandbar's cock disappeared down her throat. Rainbow Dash held Rarity's head with one of her front hooves and reached down and began stimulating her with the other. "mmm" Rarity moaned as Rainbow Dash forced her head up and down.

Rarity thrashed free and gasped for air, pushing Rainbow Dash's hoof away. Rainbow Dash whispered into Rarity's ear and Rarity grinned and nodded. Rarity turned her hindside to the cock and slowly backed up into it. Rainbow Dash grabbed it with her hoof and guided it into Rarity's pussy. Rarity arched her back and moaned as Sandbar thrusted in and out of her anonymously from the other side. It didn't take long for him to cum inside her and pull away. Cum dripped down from her pussy. Rainbow Dash stared in her direction.

"Finished already? Not much of a gentleman." Rarity huffed with frustration as she turned her nose up and then looked toward the secret passage. Her eyes widened and she let out a moan of surprise as she quickly peered behind and saw that Rainbow Dash had her muzzle pressed up behind her, lapping up the overflow of cum.

When Rainbow Dash had finished cleaning her off she worked her way down to Rarity's clit. Rarity moaned loudly and braced all four hooves tightly on the floor as Rainbow Dash strummed her clit with her tongue. It didn't take long for Rarity to reach climax. They kissed each other passionately and then embraced for a while.

"Looks like that's the last of them." Rarity said as she peered through the hole in the wall, the room on the other side was now empty.

"I guess we have something in common after all!" Rainbow Dash said excitedly.

"Yes, Darling. Maybe we should have our next fun day here." Rarity giggled. "Though I suspect that Amory Stone had something to do with it." her tone lowered and her face sank.

"Well that's the thing." Rainbow Dash brushed a front hoof over Rarity's back comfortingly. "The Amory Stone is just a powerful aphrodisiac, so it just makes you REALLY horny. But it can't actually make you do anything you don't want to do." She explained. The two mares smiled at each other.

Chapter 5: Just that easy

Rarity and Rainbow Dash crept cautiously into the secret passage. A long, dark, narrow, passage lay ahead.

"Wait!" Rainbow Dash held her hoof out to stop Rarity and then gestured with her head further up the passage.

The glow of lanterns in the distance faintly revealed two mares, an earth pony and a pegasus covered in dark ninja-like shrouding, headed their way. The covert duo strained their eyes ahead and noticed Rainbow Dash and Rarity and started galloping in the opposite direction.

"Not this time!" Rainbow Dash shouted as she took flight darted down the narrow passage in their direction, the walls of the passage just a hair's width from her wings. Rarity took off with a gallop of her own.

The shrouded mares disappeared into the glow of dawn at an exit at the opposite end. Rainbow Dash soon followed. They were long gone by the time Rarity reached the exit. The pegasus unfolded a pair of yellow wings from beneath her shroud and took to the air but Rainbow Dash streaked toward her, closing the distance rapidly.

Rarity's jaw dropped as she strained her eyes against the dawn's early light. The passage exited out to a field near Sweet Apple Acres. Out among the tree in the fields she could see Big Mac laying on his back. Applejack was riding his massive stallion cock, the biggest she had ever seen, while Cheerilee and Sugar Belle sat at either side of them holding Applejack's front hooves.

"Oh, Dear. That's-" Rarity gagged.

"Really messed up!" A high pitched voice squeeled as Pinkie Pie, dressed in black shrouding bounced up beside Rarity.

"Pinkie!? You're behind this?" Rarity gasped with shock.

"Not just me!" Pinkie Pie pointed down the path.

Rainbow Dash quickly caught up to the yellow pegasus and tackled her to the ground. The pegasus cowered as Rainbow Dash bit at her mask and pulled it off with a thrash of her neck.

"FLUTTERSHY!?" Rainbow Dash gasped in shock. She looked back down the path at Pinkie Pie and Rarity. Rainbow Dash helped Fluttershy up and the two pairs of mares met up in the middle of the path.

"I think this is the part where you two explain what's going on here." Rainbow Dash demanded.

"Darling, If this is your idea of a practical joke." Rarity huffed and turned her nose up.

"Fluttershy asked me to plan a birthday party for Discord!" Pinkie Pie squeaked.

"And um..." Fluttershy blushed and hung her head. "I wanted to make it... extra special..." She blushed as she spoke softly.

"And we heard about the Amory Stone so we borrowed it and it was super fun!" Pinkie added.

"But then we couldn't figure out how to deactivate it off after..." Fluttershy sighed. "We couldn't ask Discord for help because it's bad for his health to use his magic to prevent chaos." she continued.

"So we've been TRYING to sneak it back in and we hoped Twilight would notice that it was on and know how to fix it. But now we're going to get in SERIOUS TROUBLE!" Pinkie shouted, causing Fluttershy to cower.

"We could sneak it back and then tell Twilight we found it activated." Rarity suggested with a wink. The other three looked at her in shock.

"That doesn't sound very PROPER or LADYLIKE" Rainbow Dash teased.

"Well it's OUR investigation, not just mine. So I suppose we need to compromise." Rarity smiled. All four ponies burst into laughter.

As morning arrived Rarity and Rainbow Dash sauntered casually into Twilight's office. Their manes were in disorder and their eyes slightly red from the lack of sleep. Twilight was reading through a stack of papers while Spike stood at her side.

"Any news on your investigation?" Twilight asked.

"Uh, yeah..." Rainbow Dash said.

"We searched high and low and when we checked the relic room we found that the Amory Stone had somehow been activated!" Rarity explained dramatically.

"Really?" Twilight raised her hoof to her chin. Spike grinned nervously and stared out at Rarity and Rainbow Dash. "I could have sworn I checked on it and it didn't appear activated. Oh well." Her horn glowed and everybody instantly felt less aroused.

"Really? That's ALL it took?" Rainbow Dash rolled her eyes.

"I'm just glad things can finally return to normal around here." Twilight sighed. "I'm looking forward to your full report on your investigation." Twilight smiled.

"And just how FULL a report do you mean, darling?" Rarity asked nervously.

Rarity and Rainbow Dash both looked at each other nervously. They paused for a moment and then burst into laughter together.
