The Truth Behind Dash

In The Library

The next morning, Rainbow Dash felt...sore. Really, there was no other way of putting it, her entire body ached with sexual pain. As if the hard rutting she gave her friends wasn't bad enough, the aftermath of both the sexcapades left her off for the worst. This time, it was because of a pain in her rod caused by a shot she was given. Curse Pinkie for having that bottle of aphrodisiac, curse herself even more for taking it, not knowing about the side effects she would suffer. The only saving grace to the whole visit was that it was kept entirely private, the doctor being the regular one she saw for her routine physical exam. Other than that, it was a complete disaster.
One shower full of angry muttering and squirming later, Dash headed to her closet once again. After the last couple of days, she practically swore off tight or even mildly loose fitting pants and opted for some baggy sweats. The tent she could pitch in the front of them would still be noticeable, just not as much. Besides, she had to wear something loose anyway; the pain in her rod was excruciating.
After a little debacle with Tank, Dash was prepped to head off. Today, she was tasked with helping out Twilight in the library, much to her dismay. She had no idea why Spike had to be out of town this week, much less did she know why Twilight would need help working in a library to begin, but she wasn't about to question anything. Twilight was always an unusual unicorn, she was just glad that there wouldn't be much to do.
Dash touched down just outside the library and approached the door, though something in the air told her not to do it. She had already been found out by two of friends, what was there preventing Twilight from finding out? The pegasus shuddered as she imagined her scientific friend going overboard with her analysis of her. She wouldn't mind getting rid of her member, but she just couldn't bring herself to change how she was, not after all her years of building it up. With a deep breath, Dash headed the door. Hopefully, Twilight wouldn't find out, and if she did, then Rainbow would simply have to pray she keep her lips sealed as tight as the-
"Gah, that's right! I forgot about the others!" Dash internally screamed. Out of all her friends, the first ones to find out her secret were Applejack and Pinkie Pie!  Applejack couldn't tell a lie to save her life, and as if that weren't bad enough she was the embodiment of honesty for Celestia's sake! Then, there was Pinkie, whom of which was extremely likely to blurt it out right in front of crowd, even with her Pinkie promise. Dash started beating her head against the wood of Twilight's house, convincing the librarian inside to step outside to investigate.
"What going on out here?" inquired Twilight, worried over the reason she found Dash beating her head into the wall. The pegasus looked over and was immediately left breathless. Twilight was wearing a white shirt with a missing midriff and exposed her cleavage perfectly. Twilight was in-between Rarity and Fluttershy with how perky and practically perfect her breasts were. Not too big, but certainly round, they left a lasting impression that always got noticed. She also wore a dark brown miniskirt that hugged her hips just right, showing off the girl's incredibly figure in ways even the librarian herself didn't understand. Rarity called it a natural gift to be bestowed with such an incredible figure, then when Twilight wasn't around, she also mentioned how wasteful the unicorn was for not showing it off more.
Getting annoyed at Dash's mindless staring, Twilight furrowed her brow and walked over, adjusting her glasses as she strolled by. "Rainbow, if you're going to stare, the least you can do is work with me" the unicorn explained, her tail swaying with each step she took.
Dash merely shook her head and suddenly saw Twilight the way she always was. She wasn't entirely sure why the first glance at her friend practically had her smitten, but she mostly blamed it on the season. Even if she wasn't exactly female, she still suffered the same effects as the heat season, such as seeing others in a haze of beauty. Still, Twilight looked pretty even without a haze of heat forcing her to look better in her eyes.
"I uh...had some trouble the last couple of weeks" Dash lied, Twilight quirking an eyebrow. A small bit of sweat dropped down Dash's forehead, along with a small trickle of blood.
Twilight went wide-eyed. "Rainbow, you're head is bleeding!" she stated, grabbing hold of Dash and dragging her inside. Rainbow didn't bother resisting, she was too busy smelling the vibrant fragrance that was Twilight's mane. She had likely switched to a new shampoo as of late, and Dash couldn't get enough of it.
Once the bleeding was stopped and the wound was patched up, Twilight let out a sigh. "Why were you so upset earlier?" asked Twilight, a quizzical expression behind her glasses.
"You wouldn't get it" Dash sighed, scratching the back of her mane.
Twilight merely put a hand on the pegasus' shoulder, smiling at her endearingly. "You don't have to hide your feelings from me" she said, Dash's heart beating slightly harder now.
Dash seemed to be at a small impasse. She couldn't exactly trust Twilight with such a secret just yet, but she couldn't lie after hearing what she did either. "It's kinda personal..." was all that she could come up with. Twilight simply gave a sad look. For a second, Dash wondered if she should've just come clean and told her, but her thoughts were interrupted by the sudden soft and warm feeling appearing around her. Twilight was hugging her, both of the unicorn's arms wrapped around her back while her head gently rested upon her shoulder.
"It's alright if you don't want to tell me, but know that I'm your friend, so I'm there for you" Twilight delicately whispered into Dash's twitching ears. Dash merely smiled and placed her hands around Twilight's lower back, only for the unicorn to break the embrace as soon as she got into it. "We should get to work, those books won't organize themselves" Twilight added as she got up, offering a hand to Rainbow, whom of which took her up on the opportunity.
After their little moment, Dash had gotten to work, helping Twilight move a few books from one spot to another, generally maintaining the library. Twilight was moving a few things on higher shelves on the top of a small ladder, moving a few novels into place with her magic. Dash was in the middle of carrying a small stack of books when Twilight called out to her.
"Rainbow, do you mind moving a few of these to the empty shelf over there?" she asked, levitating a few novels just above her.
"Sure thing, Twi" Dash said as she walked over. Twilight plopped the books down on the already-established stack that Dash was carrying, the pegasus grunting when they had made contact. Of course, Dash was so focused on the books in her hands that she didn't notice a small book out of place, right next to her foot.
Naturally, she slipped on the paper of it and fell face-first into the ladder, knocking Twilight right off of it. The purple unicorn fell straight down with a thud, right on top of Dash to make things worse. Dash groaned slightly, the sudden smell of lavender filling her nostrils. Looking up, she found a cringing Twilight lying right on top of her.
'Oh, come on!' Dash thought, red in the face. She could feel every inch of how warm Twilight was, and Twilight could feel exactly how hot Dash was getting and tried to get up, but not before Dash could sneak a peek down the librarian's shirt, revealing that Twilight apparently wasn't wearing a bra, furthering Dash's fluttering heartbeat.
Twilight leaned up and scowled once she found the source of all this nonsense, an old comic book that Spike had carelessly left sitting around had fallen onto the floor. The librarian sat upright and tried to get off what she first thought to be a pile of books, but later found to be something much...harder? Looking down, she found that her hand was practically around some cylindrical base, located right in front of Dash's pants. With a gasp, Twilight jumped up and leaned back against the nearby shelf, a little frightened by the revelation.
Dash on the other hand was lying down, having a miniature panic attack. She was having the absolute worst run of luck imaginable this week, having been found out by three out of her five closest friends after having kept it secret for all the other twenty-one years she had been alive. And yet, here she was, her secret found out for the third time in one week. It just didn't make any sense. "I think I'm cursed or something" Dash muttered under her breath as she tried to calm down Twilight, the latter of whom starting to babble as her brain slowly started melting out of her ears.
After a couple of seconds of shaking of her, Twilight could finally form coherent thoughts once more.
"Rainbow, what the hell is that-that....that thing in your pants?" Twilight demanded in a panicked tone.
"It's...well, you're gonna have to promise me you won't freak out, or that you won't tell anyone" Dash stated as she looked the librarian dead in the eye.
Twilight flinched slightly under Dash's gaze, though she still managed to nod. "I promise" she calmly stated with a slight blush appearing across her face.
"Alright, just remember, you promised" Dash reminded as she reached for the waistline of her pants. Slowly, she pulled the front brim downward, letting the head of her member poke out. Twilight seemed to lose a little color in her face as Dash's pants went completely down, the bulging, blue rod suddenly being visible.
Saying that Twilight panicked was an understatement. The poor unicorn was shaking, her back against the wall as sweat started to form on her brow. Dash's member had slowly started hardening under Twilight's gaze, her face going red as her wings unfolded slightly.
"I...I don't know what...why....how...?" and other such ramblings were all the librarian could say.
"It's...something I was born with. I'm a hermaphrodite, Twilight" she deadpanned. That at least managed to calm Twilight down enough so that she could start thinking things through as she always did.
"Why is it you never told me?" Twilight asked, now a little concerned.
"I told you, it's personal" Dash responded, a little defensive
"Then...does anypony else know?" Twilight inquired.
"Just...Applejack and Pinkie" Dash stated after giving a short moment of thought.
Twilight merely blinked and gave the pegasus an incredulous look, occasionally glancing down at her crotch, making Dash start pulling her pants back up due to the lack of comfort Twilight's eyes was causing. Twilight telekinetically stopped Rainbow's waistband, earning a confused-and slightly aroused-groan from Dash.
"So...since you're a hermaphrodite...that means you have a vagina too, right?" she suddenly asked, avoiding eye contact.
Dash slowly nodded. "Uh-huh".
Twilight got a bit closer, making eye contact once more. "Can...would it be okay if I...saw it?" she asked, standing right in front of Dash now.
If Dash didn't look like a cherry wearing a rainbow wig before, she certainly did now. Her most logical friend, the pony who managed to find a reasonable explanation for the craziest of things and then some, was trying to get her to strip down more. The poor pegasus' wings were completely unfolded, now standing straight out of her back at either side, her heartbeat increasing as her member throbbed to the beat. Twilight leaned down, making Dash's answer for her as the latter pushed her testicles away, giving Twilight a close look at her pink, fleshy slit.
Twilight simply leaned in, seemingly intoxicated by the overwhelming amount of Dash's musk flowing everywhere. All the sudden attention to her privates caused Dash's vulva to quiver slightly, a small, thin trail of her sexual juices starting to drip from it as her member began swelling. By the time Twilight looked back, Dash's rod stood at full mast, the pegasus' tail twitching about incessantly. The librarian had subconsciously rested her hands on Dash's inner thighs, caressing them gently as she leaned in towards Dash's pulsating member.
Dash simply took a step back, tripping and falling backward due to her pants being around her ankles. Somehow, this action had managed to snap Twilight out of her lust-ridden haze and to her senses. The librarian stood up and headed over to Dash, trying to avoid the throbbing monster in between her legs. "Are you okay?" she asked, getting nothing but a groan from Dash. Sitting upright-which was much more difficult than you'd think-Dash looked at Twilight, noting the slightly glazed-over look in her eyes. For the most part, she was actually grateful that Twilight didn't jump her right away, though the sudden kiss from the other mare was something that had startled her.
Twilight pulled away, blushing profusely as she scooted away on her knees. "I'm sorry, I-I just don't know what happened, it was like I was driven by something" Twilight tried to explain. Dash simply looked at her friend for a moment, until a familiar scent began forming from her, completely unlike the other fragrances she had sensed. As it would seem, even little-miss-recluse went into heat from time to time, this was just the first likely time where somepony else had been around to inspire such feelings.
Twilight looked down at Dash's rod, noting the twitching sensations it seemed to experience. "Doesn't that hurt?" she asked, a little shy.
"It does that, but I'm...alright" Dash responded, subtly scooting closer to the aroused mare. Twilight had simply blushed hardly, unknowingly looking at Dash with a pleading look, her breathing heavier. "Are you alright though, you look kinda uncomfortable" she added, sitting up to put an arm on her shoulder.
"I'm not so sure...my breath is all ragged, my body's burning up, and there's some kind of tingling in my crotch" Twilight stated, her face slowly contorting as she described everything.
Dash simply giggled and leaned in, planting a little kiss on the unicorn's cheek. "No need to worry about that, you're just horny" Dash explained in matter-of-fact tone. Twilight simply went wide-eyed at the statement, her heart rate sky-rocketing.
"Is that a bad thing?" she asked, getting a surprised chuckle from Dash.
"Are you serious?" the pegasus asked. Twilight nodded, only making her laugh further. "Didn't you ever take sex ed?" she asked, Twilight shaking her head this time.
"I had a few other things on my mind at the time, like graduating at the top of my class" she explained, her ears folding against her head. Dash simply leaned in and smiled at her. "Don't you worry your pretty little head about it, I can teach you all you need" she stated.
After a couple of minutes passed, the two mares stood in Twilight's bedroom, both of them naked (save for Twilight's glasses). Dash walked over and initiated a short kiss, Twilight's tail whipping about in reaction. Dash broke away, leaving a small trail of saliva between her mouth and Twilight's. Dash giggled slightly as the soft hairs on her partner's tail swished about against her hands. The two embraced soon after, Twilight quivering from the pulsating rod poking against the underside of her breasts.
Dash led Twilight to the bed, the two sitting a kissing once more upon it. Dash's tongue fought against Twilight's on the inside of the latter's mouth. Twilight shuddered subtly, tickling Dash as the two started lying down, Twilight's body being positioned to face the blue obelisk. "Just start licking it" Dash instructed, Twilight blushing as she did so. Slowly, Twilight grabbed hold Dash's member, gripping the fleshy mast  as it seemed to harden under her touch. She stuck her tongue out and placed it down at the base of its sheathe, already satisfied from the taste. She dragged her tongue all the way up to Dash's medial ring, where she started planting soft kisses up to the flared head, small beads of precum beginning to dribble down the sides.
While Twilight ministrated, Dash was treating to a cute, slightly red set of puffy lips inches away from her face. She grabbed hold of Twilight's flanks and started massaging the lavender buttocks carefully, earning a few pleasured mewls from the librarian. Twilight's pussy had started dripping a few fluids onto Dash's chest, enticing her get a taste of her friend. Slowly, teasingly, Dash stuck out her tongue and started licking over the tender flesh, Twilight letting out a sharp gasp as she did so. Just as she expected, Twilight's pussy had a sweet taste to it, happily lapping away at the folds and even sticking her tongue deeper.
While Twilight started reaching higher on Dash's rod, she subconsciously bucked her hips back, desiring Dash's tongue to try and reach deeper. Eventually, the mare had her lips resting right around the top of Dash's crowned head, her tongue wrapping around the base soon after. As her eyes glazed over, she popped the first few inches of Dash's twitching rod into her mouth and started massaging it with her throat muscles. Dash started letting out soft moans, her every breath causing Twilight to shudder, both in body and vulva. The pegasus soon began suckling around Twilight's winking clit while Twilight took in another few inches. The only sounds in the room were the passionate schlicking of tongues across each other genitals and a few small moans here and there.
Twilight's body started getting hot all over, the librarian panting heavily by the time Dash pulled off and re-positioned themselves. Dash was now lying on top of Twilight, lining up her rod with the latter's opening. The pegasus gave a small thrust as soon as she was close enough, causing the librarian to wince as her hymen was quickly snapped. The way Twilight's virgin-pussy muscles started gripping her, she was amazed that she didn't cum on the spot. She leaned down and planted small kisses across Twilight's face, the two's nipple rubbing against one another as Dash began moving.
She only moved slowly, wanting Twilight to enjoy every second of her first time. Also, because the unicorn's vaginal muscles were so tight, she could hardly even move to begin with. Twilight was already a sopping, sweaty mess and they had just barely gotten started. Dash chuckled at the former-virgin and started kissing her again, adding her tongue a few times as the other moaned into her mouth. Dash had started going mildly faster, the tightness giving way from the slickness of her internal juices. Soon, Dash was already in up to her medial ring, Twilight gasping as the ring of flesh popped in and out of her throbbing snatch. Her soft moans only aroused Dash even more, causing her to start thrusting faster, each one bringing a new wave of pleasure for the both of them.
Twilight eventually wrapped her legs around Dash's back, her hands doing the same a bit higher. As she and the pegasus kissed, Twilight began digging into the base of Dash's wings with her fingers, the latter feeling her pleasure build up sooner from the sensitivity. She leaned down more, squishing her breasts against Twilight's as her rod started digging deeper through Twilight's ever-tightening walls. About thirty seconds later, Twilight's internal walls started clenching Dash's rod harder, the unicorn arching her back as a high-pitched gasp escaped her lips. All the pressure building up made Dash tense up as well, her own orgasm coming immediately during the middle of Twilight's. Soon, cries of pleasure filled the bedroom as Dash started shooting small ropes of hot seed up into Twilight's womb, the latter's breathing all but halting under the force of each shot.
Dash soon collapsed on top of Twilight, her spasming rod finishing up its last few squirts as the two mares slowly tried to catch their breaths. "That...was...awesome" Dash breathed with a wide grin and a sly smirk. It felt incredible to finally have some control over her sex partner, after the last two jumped her without any warning and even less control of themselves. Twilight initiated a kiss with the cyan mare, caressing the latter's toned back muscles as they embraced.
"So...what happens to us now?" Twilight asked as Dash started pulling out of her.
"I don't really know" Dash responded as she kissed and suckled at Twilight's neck. "But I guess it doesn't really matter. As long as I've got you, nothing else does" Dash added sweetly, making Twilight smile. The librarian had taken off her glasses sometime during coitus, showing off her positively beautiful eyes. The two shared a long, passionate kiss, not caring about anything else. Sure, Twilight had a few more questions to ask once this was all over, but she was too busy focusing on her new lover to pay it any mind. For the time being, it was quaint enough for her.

Sorry if it took forever this one's a lot longer than usual :3  hope y'all enjoyed it ! ;)
