After spilling her tea, Fluttershy spills her guts as to how she knows so confidently Rainbow Dash is into colts through a first hoof experience under covers.

Allot happens in trade school dorms. Especially with Rainbow Dash as a roommate.

This is a first person story from Fluttershy's perspective as she reflects on a past event to Twilight after an awkward conversation. However, even though she tells Twilight the truth, its not exactly the whole truth.

Under The Mattress

I wish I hadn’t taken that long sip of tea. Not because of the tea itself. It was my favorite flavor after all; mint. I loved its cool taste, but just wish it wasn’t halfway down my throat when Twilight asked, that question.

“Fluttershy,” she asked with a straight face across the tea table at my house. “Do you think Rainbow Dash is into mares?”

My cool mint burned as I coughed half of it back up. It took me half a minute to recover as Twilight looked on with concern.

“Why, why ever would you ask that?” I said trying to avoid the subject. I failed.

“Well, I’ve seen everypony else entertaining a colt at some point, or at least get nervous around the subject, like... you.”

My flushed cheeks did me no favors in protesting that.

“But,” she continued as she tapped her front hooves together. “Rainbow’s the mystery. I mean, I have nothing against that, but I’m just curious.”

I sighed knowing what was about to come. I could have just lied and went along with Twilight’s theory, but that would’ve wrong. Once Twilight found out I lied… I had to tell her the truth.

“No,” I said hoping to Celestia the conversation would stop here. “ She’s into colts too. Dashy’s just... very private about girly thing.”

Twilight scratched her chin in thought.

“I suppose that is true, but how can you be so sure.”

I cursed my pale complexion, and its inability to hide the embarrassment revealed in my flushed cheeks when I glanced away. Twilight, ever the detective, would never let such a clue go by. And this time was no exception as she leaned forward across the table with an oddly mischievous grin.

“What are you not telling me, Fluttershy?”

I leaned backward in my chair as far as I could in a last ditch effort to avoid the that story.

“Fluttershy?”

I met Twilight’s inquisitive gaze. Her eyes were as bright as a filly’s on Hearth’s Warming Eve, and it was at that moment, I knew I had to give in.

“Pinkie Promise, not tell Rainbow… or any other pony,” I said even more squeaky than normal.

“Promise.”

However, even with Twilight’s improving Pinkie Promise, with half as much eye gouging, I dared not tell her, everything.

***

Before moving to Ponyville, Rainbow Dash and I were already close friends. It was no surprise that when we wen trade school we bunked together as roommates in Cloudsdale, back when I used to have, a slightly shorter manecut. And it worked out for the most part.

Though, I’ve since come to believe having teenage Dash as a roommate was what prepared me for Discord.

Our dorm room was small, with a bunk bed and two desks. Dash, of course claimed the top bunk, but I didn’t mind. I had more freedom to decorate the bottom bunk, and put on a soft, hoof knitted bed sheet that drooped to the floor, and provided a nice crawl space to hide under when things get too noisy. Which, with Dashy, was all too often. How she could fit 30 ponies in our room for a party was as big a mystery as Pinkie Pie.

Though we shared a bed, we were both glad to have our own desks. Dashy & I have, very different definitions of organized. I was busy at mine one day during winter break, knitting sweaters for a new litter of rabbits from the veterinary department. Until I heard ponies approaching the door, quite loudly.

Instinctively I quickly threw all my knitting fabric into its desk drawer, and bolted under my bed, using my wings for a slight boost in speed instead of flight. I did all this in one swift movement that I’ve got plenty of practice with over months. It’s not like I had anything to be afraid of, but I found avoiding her friends more convenient than interacting with them more often than not.

The knitted cloth covering my sanctuary had just stopped blowing when the door creaked open. Well, slammed open. Silently, I watched through the thin holes in my bed’s cloth. The kind all knitted cloth has. Luckily, my bed sheet was made with a color pallet matching my own for an added degree of invisibility. My breath stilled as I waited to see what guest Dash had brought today. At least, I hoped it was Dash.

I let out a very quiet sigh of relief as Rainbow trotted through the door followed by Thunderlane. Dash at the time had more a more wild, and unkempt mane. She only ended up up with her current cut after I mentioned the aerodynamic benefits of mane-gel. Thunderlane, I recognized instantly from his dark grey coat and silver mane from the weather students enrolled with Dash. I particularly remembered him for the teasing Rainbow always gave him.
Something, I unfortunately related to.

That day however, he appeared almost as nervous as me when he stepped into our room, and his eyes darted around. He quickly noticed our desks in the corner. It was not odd for many to be drawn to the stark difference from Rainbow’s mess of a desk littered with Wonderbolt paraphernalia, and my clean desk with a light pink coat of paint.

“Where,” he began with a nervous stutter in his voice. “Where is your roommate. Flutterhide?”

Rainbow responded to Thunderlane’s fears with a strong, forceful kiss on his lips that nearly knocked him off his feet. My own body jolted in surprise of the passion.

“I didn’t bring you here to talk,” she said with a sly grin. “And don’t worry about her. Fluttershy is likely busy with all those new baby animals.”

She followed that up with another kiss. And even from across the room, I could tell she was using her tongue. Thunderlane quickly followed her lead, as I turned my head away.

Twilight burst out in laughter across the table.

“That‘s priceless,” she said after getting in a gasp of air. “I can’t believe she made out in front of you.”

My gaze remained fixed on my teacup my hooves were actively fiddling with as I decided how I should proceed. It felt good to vent this.

“Um,” I mumbled finally looking up to a giddy Twilight. “That is not the end of the story.”

Twilight Sparkle froze in silence. Her gaze focused on me as she grew pale.

“No.”
“Yes...”

***

Rainbow Dash leaned further into her kiss with Thunderlane. Her tongue seemed to winning the war of the mouths from my perspective as before long Thunderlane pulled himself back, gasping for air.

Rainbow giggled, and licked her lips.

“Virgins are adorable.”

Thunderlane turned his head away, in shame.

“It’s not my fault,” he said before letting out a girlish yelp as Rainbow grabbed his sheath, and started massaging. His body involuntarily shivered in bliss barely able to stand.

“Wha, what are you doing?”

Rainbow responded with a short kiss.

“Quiet,” she said as she leaned down to his sheath, and started massaging it again, gently with two hooves that time. His cock slowly started to peep out, and Rainbow planted a gentle kiss on its head. Thunderlane flinched at the moist touch of her lips. His member grew rapidly as his jittering back legs parted several more inches to give Rainbow more access to his colthood, and myself a better view.

Rainbow planted her rear on the floor next to Thunderlane, and leaned her whole head under his chest, making sure to rub herself alongside him like a cat in heat. She planted her lips softly on the end of his length, and allowed it to finish growing, into her mouth. I knew he was finally, fully extended when what two inches of his girth pulsed like a balloon ready to pop.

Rainbow started to go to work with a slow pull out that stopped at his head, and left the rest of his cock exposed and gleaming in saliva. Her hoofs started to play with his ball sack as she ejected his head like she was breaking away from a kiss. Thunderlane’s left eye twitched erratically as his mouth gaped open, but failed to find any words.

“I’m impressed,” she said as her right hoof grabbed his slick member, and proceed to pump it back and forward as Thunderlane bit his lip.

“Usually first timers are much lighter triggers,” she began to say as his first wave of cum rocketed out from his cock, and splattered above her right eye. Rainbow barely managed to close her eye right before Thunderlane’s thin white glaze trickled over it. The second load struck her snout before spraying down her neck.

Dash frowned, and quickly swallowed his cock’s tip as the third, fourth, and fifth waves of cum splashed into her mouth. Each shot made her cheeks pulse slightly. Thunderlane’s hips also thrusted forward with each wave of pleasure. Dash sucked his end trying to keep all his nectar in, but a few drops dripped to the carpet with each thrust.

After a minute of eternity, Thunderlane’s body finally relaxed. He leaned backward, and popped his limp shaft out from Rainbow’s mouth. Rainbow tilted her head back as she swallowed Thunderlane’s cum in two gulps, and licked her lips as she stood from the floor.

“Right when I was giving you a compliment,” Rainbow Dash said as she glared Thunderlane. He shrunk under her gaze with a mixed complexion shifting from ecstasy to terror. His seed dripping down her face did not help with his fear.

I watched speechless from under my bed. I never imagined Dashy was into this sort of thing. I knew she had urges, and frequently relieved herself of them. But to drink it? She was always such a tomboy.
Worse yet, I could not believe I was into it. I tried to ignore the growing warmth in my own nether regions, pretend it was just my imagination, but I couldn’t. As Rainbow chewed out Thunderlane for cumming without her permission, I could feel my vagina growing wet. But I wish it would have just ended there.

“So, ready to return the favor?” Rainbow asked Thunderlane as she stepped towards my bed. My heart rate spiked as heard the creek of bed spring overhead as Rainbow Dash laid her front half onto my bed. Her back legs spread where they stood before my peek holes. I couldn’t see, but knew she was revealing her sex to Thunderlane. A fact made all too apparent by the rekindled spark in his eyes as he stepped forward.

“You do know how to return the favor for on a mare, right?”

“Sure,” he replied with a nervous gulp I heard from below my mattress with ease. Luckily my own was much quieter as Thunderlane’s face disappeared from my view when he neared Rainbow’s rear. What I could see of him, his legs, stopped inches away from Dash. A brief moment of silence followed as he gazed at Dash’s rump. Well, silence would’ve been an incorrect description.

Thunderlane’s thick breaths were very audible as they blew over Dash and my bed covers with the faintest trace make its way down to myself. However, what was worse, and so embarrassing to listen to was the faint squishing sound of Rainbow’s sex winking at Thunderlane. I didn’t need to see it, to see it as clear as Thunderlane did.

However, I had seen it before, which left little in the way of imagination. Her soft cyan coat gave way to subtle folds normally hidden under her bright tail ,colored her namesake. Those folds opened up to a surprisingly soft pink colored slit which she had already revealed herself to me before countless times. We had grown up together since we were young fillies that just earned their cuties marks. Of course we had bathed together. And as a young filly I never appreciated Dash’s comparison of its color to my mane, but I couldn’t exactly deny it either.
And I could never forget puberty, and all that entailed. Dash was the very mare to introduce me to masturbation after all. Well, introduce wouldn’t exactly be the most accurate description; more felt compelled to explore with me the one thing she did take away from the sex ed class at our very next sleepover. First she started with her hooves massaged my cliterious with grace unbefitting of Dash’s character. Then she played with each flap in a much less gentle manor. The jump from soft to forcefully pushed me over the edge. However, amongst the ecstasy of my first climax I soon found my face to her rear as she wasted no time taking the 69 position, I later found she learned from one of her father’s “comics.” I had opened my mouth to protest only to have it filled her salty juices when she lowered her cunt. My resolve to protest vanished the second her tongue, started returning the favor.

So needless to say, I knew all too well what Thunderlane faced when Dash moved her tail.

Thunderlane leaned in a quick jerking motion, and rapidly started lapping up Rainbow’s juices. I could tell she enjoyed the affection by a proceeding moan. Well, I also felt it quite literally as Rainbow pressed herself down harder on the mattress above me.

I couldn't take it anymore, and turned away from Thunderlane’s work on Rainbow’s rear. I closed my eyes, and tried to drown out the sounds, but that only made it worse. My mind couldn’t help but draw the comparison of a dog lapping up water on a hot day. And that lead to a more accurate picture of Thunderlane fluttering his tongue between Rainbow’s thighs with the added fictional bonus of a dog collar. I flung open my eyes to escape such visions, and go with plan B. Focus on the wall.That, was a huge mistake.

Every dorm room, at least for mares, came with an extra large mirror. Me and Dash assumed they expected we needed it for makeup and such. However, I found it quite intimidating. And Dash, could care less about mirrors. She was more worried we would break it, and jinx her chances of joining the Wonderbolts. So, we decided to stash it away behind our bunk bed as there was just enough space to slide it in, and cover it up with a protective cloth I knitted myself. Well, that cover had fallen off, likely from one of Dash’s jolts of pleasure I failed at ignoring just seconds before. I was given an unnaturally clear view through my knitted bed covers of Rainbow’s sweat covered brow half buried into one of my own pillows as Thunderlane’s head bobbed back and forward, and all around behind her tail. And I just froze, unable to move, for about a second.

I couldn’t resist it anymore. Rainbow’s whimpers as she neared a climax had forced my hoof... towards my own throbbing desires. My front left hoof, the one I prefered for such uses, could feel the heat radiate off my vagina’s surface after it snaked its way under my belly. I bit my lip as I pressed up and fought off an early orgasm.

Rainbow proved less fortunate in that regard. She let out a moan as her body shuttered. Thunderlane pulled his face out from under Dash’s tail with her juices still dripping down from his lips. He exhaled loudly, finally remembering to breath after his job well done.

With mixed feelings, my hoof started to slip away from my own wet urges. I was relieved, yet not at the same time. Until Rainbow slithered herself onto my bed.

Rainbow turned around on my matress, and batted her eyes at Thunderlane. Her head above the foot of my bed as her rear winked at him seductively from the other side. He was putty in her hands as made evident by his own drool mixing with the traces of Dash’s satisfaction still trickling down his face.

“Don’t keep a mare waiting.”

Thunderlane sprung towards Rainbow using his wings for an added boost of speed, that unfortunately caused him to whack his head across the bunk bed’s upper rail. Rainbow giggled at the whole affair before Thinderlane dizzy in more ways than one tried to align himself to mount Dash. After a moment of hesitation, he lifted himself on top of Rainbow, and slowly started sliding forward until his once more hard colthood bounced off the thin space between Rainbow’s two holes.

“Make, sure you get the right one,” she said playfully.

Out of fear, or relief, Thunderlane stabled himself and aligned his lance to its target. With one solid thrust he drove it into her. He guessed right as his dick slid its full length into her well lubricated love tunnel. Rainbow moaned in ecstasy, and bit her lip playfully waiting for Thunderlane to continue.

Another eternity seemed to pass before he started thrusting his hips. I imagined, he had to fight the urge to cum from the first moment he entered by the look on his face. However, once he started, he made up for lost time with each passionate thrust that shuttered the bed, and pressed down on me from above.

My already weakened resolved gave in to my animal instincts once again. My body was already aligned with Rainbow’s, so I felt each thrust smack into my rear along with her own. My hoof went to work hoofing my folds in unison with the action above as I pictured myself swapped in Rainbow’s position. It was not hard. Especially since it was all going down on my bed!

I moved my free hoof to my mouth, and bit down gently to keep my moans in check. Luckily, right as a Thunderlane gave a shove that knocked my hoof an extra inch in, and made me & Rainbow gasp. I knew my time was limited with that gasp, so started hoofing myself with increased speed. My elbow became a fulcrum that allowed me put even more pressure into it, and more importantly, feel even more of every thrust.

Thunderlane didn’t last long as was to be expected with the rapid pace he took. His face was the first clue I noticed in the mirror, as his eyes slammed shut. Muscles across his face spasmed, and he let out a loud, yet muffled, grunt as his wings flung outward. I was not the only one to notice, as Rainbow’s tilted head joyfully watched the virgin colt’s cum face. Rainbow in response started thrusting her own hips alongside Thunderlane’s spasms. Within moments, her head dropped to my sheets as her own wings spung outward with her climax.

I was the last, and scared I would be noticed as I frantically hoofed my dripping vagina. Thank Celestia Thunderlane decided to pull himself out right at that moment. His drooping wings hid little as his cock popped out from Rainbow, and a river of cum flowed out onto my sheets. The sight was the last trigger I needed. I bit down on my free hoof hard, as the other gave one last thrust. My body quietly fell to the ground, and spasmed in the best orgasm I’ve ever had up to that point, and left me barely in control of my own body as my juices squirted out. What control I did have was fully devoted to not being noticed as a puddle expanded at my rear. I wasn’t able to walk for a good 15 minutes afterward.

Luckily, for me, the sound of other ponies outside our door spurred Thunderlane & Rainbow Dash into action, and ended their rather passionate post sex kiss, I missed when I attended to my own needs. They quickly, and poorly, wiped up their mess with half a box of my tissues, before leaving. Thunderlane was still flustered, and on cloud nine as he left our room. Rainbow on the other hoof left with merely a mischievous grin.

“And, that is how I know Rainbow Dash is into colts,” I said surprisingly boastfully to a blushing alicorn princess.
Well, that, and all the other sessions.

Author's Note

My first foray into the world of clopfics.

Originally, I intend this to be a one off, but might break it into a series following Flutters accidental, and intentional exploration into Ponyville's perversive side.

That is, um if its ok with you.
