Fluttershy was feeding random animals in a bush as Rainbow arrived. "Heya Flutteshy, what's happening?" Rainbow asked as she hovered nearby, causing the animals to scurry into hiding.

"Oh, hello, Rainbow Dash. I'm doing very well, thank you for asking. How are you and Applejack?"

"Why do you wanna know about just us?" Rainbow asked crossing her arms defensively.

"Oh, I'm sorry if I offended you, Rainbow Dash," Fluttershy replied turning her head so her mane covered her eye, "I was just asking because you're always challenging each other and I was curious if she’d made a move yet."

Rainbow Dash relaxed her forelegs and her jaw opened in shock.

Turning her head back to Rainbow Dash, a slight smile crossed Fluttershy's face. She dropped the last of the nuts and berries into the bushes, then turned to face the hovering mare before her. "THe birds and the bees keep me informed of certain things that happen around the area, and I think it's wonderful you two are so much happier lately. I spoke with Applejack Sunday, and she was very happy to have seen you at her friends party. She wouldn't say why but she was smiling a lot."

Rainbow's eyebrows raised slightly as she listened and pressed. "So, she was happy to see me? What'd she say? Did she tell you what we did? Was it really as awesome as I thought it was?"

Fluttershy quietly giggled into a hoof. "Well, only that you went to a party and you two won a game, and that she was very, very pleased with how well you played."

"Yeah, I knew it,” Rainbow inverted and flew with her belly to the sky effortlessly. “No one even had a chance to beat us. We're unstoppable when we team up." Fluttershy chuckled as she turned to walk back to her cottage. "Hey, Fluttershy, where ya goin? Wanna come with me to see Twilight?"

"Why don't you want to see Twilight alone, Rainbow Dash?"

"It's nothing really, just she and I haven't talked for awhile, and now we have something between us that I don't want to get in the way of our friendship."

"Well, if it's important you should talk to her about it. She is your friend, after all, and she will understand. How can you solve a problem if you don't talk about it?"

"Well," Rainbow began rubbing the back of her head as she righted herself and followed the walking pegasus into her cottage. Rainbow thought of a response but couldn't make sense of one. "Ya know, Fluttershy, you should open a stand and charge people for your advice. You'd make a lot of bits."

"Oh," Fluttershy giggled softly, "I couldn't do that. I need to make sure all my critters are healthy first."

"Yeah, I guess. So, what's new with you, Fluttershy? Taking any trips or anything?"

"Oh, well. No actually. I may go to Trottingham next month to check the health of a few creatures at their zoo, but that's all. Why do you ask?"

"Because I'm bored, Fluttershy. I have a hours left to kill before I get to see AJ, and I don't know what to do."

"Well, you can go talk to Twilight and work out your problems, then you two can arrange a picnic or spa day for us all, and if you need me, I'll be here and you can come to me for advice."

Rainbow rolled her eyes then said her goodbyes to Fluttershy. Heading back to town she went straight for the Golden Oaks Library to see Twilight.

Twilight was sitting at a desk reading a book on pre-industrial Equestrian hay baling techniques, when Rainbow Dash flew in through an open upstairs window. "Heya Twi, what's new? I just got done talking with Fluttershy and she said I should get something off my chest."

Turning around in her chair Twilight smiled. "Hi, Rainbow Dash, I haven't seen you for over a week. I hope everything's okay…” her smile was forced, but Rainbow didn’t notice. “What can I help you with?"

"Well, you see, I was wondering about..." Rainbow thought for a couple seconds raising Twilight's suspicion, "the history of... um, the Golden Oaks Library?"

"You want to know the history of the library? Where I live and work? Rainbow, are you sure that's why you came here?"

"Okay, Twi, I really wanted to talk to you about Applejack." Twilight took in a deep breath and held it for what felt like too long as they waited for the other to speak first. Rainbow Dash started. "You see, I heard about you two and what you had for a while, with Applejack."

"How did you hear about us?" Twilight said as she began to glare at Rainbow Dash, "Did you tell anypony else? What did she tell you? Did you believe her? Who else did she tell?"

"Woah, woah, woah, Twi, it's cool. She just told me about you two after we..." she gulped as she trailed off.

Twilight's magic lit her horn as she climbed to the floor. "What? After you what?"

"Uh, Twi. I think I should go-"

"No,” the purple mare’s eye twitched, “please, answer me Rainbow Dash," Twilight said as she stomped a hoof on the floor to make her point, “what did you two do, exactly?” Rainbow was still hovering in the air and started backing up as Twilight made a approach.

"We, well, she came to my house and a lot happened with kissing and then well, we had sex back at my place and then… then we had breakfast and did it again and after that time was when she told me about you two," Rainbow blurted.

"What. The. Spell! You two had sex. On the first date?! A lot?!"

"It wasn't a date, she just came over to eat and talk. Everything else just happened! It wasn’t planned, honest!"

"THAT'S EVEN WORSE!" Twilight shouted in shock and disbelief. "You and her. She and you. The both of you?! I didn't imagine she'd really... Why... Ugh! What about me? How could she move on so quickly? I mean a few months and she’s already got a new special somepony while I’m here with my books?" she shouted to the nearest bookshelf.

"Uh, Twilight? I think you're broken again."

Twilight’s horn started to glow again as she locked her eyes on Rainbow Dash. Rainbow Dash didn't like where this was going. “Yeah, uhm, I’m gonna head outta crazy town for a-” she found herself shrouded in a magic field that suspended her in the air. "Twilight? What're you doing? Let me go. This isn't cool." Rainbow tried to move but to no avail, and she began to feel very nervous as Twilight looked at her.

"Spike is out doing errands and we have a long time to talk about this. Alone." The sound of locks clicking, doors being shut, and drapes being drawn around the library gave Rainbow the chills as she looked into Twilight’s face. Rainbow tried to talk, but her mouth was closed magically as she began. "Rainbow Dash, let's go down stairs and have a talk." Opening a closet she levitated a rope to her back as Rainbow Dash shouted through her closed mouth with terrified eyes.

Twilight moved a chair from a desk to the middle of the room and set Rainbow in it. Tying her wings to her body and then her body to the chair tightly, Twilight released her magic field and started at Rainbow.

"What the flock are you doing Twi? Let me go before I get out myself and kick your flank to tomorrow," Rainbow shouted as soon as she could open her mouth again.

"Rainbow Dash, you're in no place to make threats... if you even are the real Rainbow Dash! I know Rainbow Dash was in a relationship with Soarin, a member of the Wonderbolts,” Twilight started pacing around. “A stallion she idolized and worshiped, and then broke up with suddenly after engaging in a relationship with... for reasons unknown. Less than a month later she turns into a fillyfooler and seduces the mare I was with?"

"I did NOT seduce anypony, Twilight," Rainbow shouted as she struggled against her binds.

"Sounds like changeling magic to me!" With a sudden burst of light from her horn, a beam of mystical energy engulfed Rainbow Dash as she screamed in fear at the arcane magic blast.

Nothing happened.

"Okay, so you're not a changeling. Or maybe you're a type of shapeshifter I don't know about." Another spell blast at Rainbow, causing her to only flinch as nothing happened. "Okay, maybe you're a demon, ghost, ghoul? Something?" Another spell followed another, yet nothing happened.

Rainbow glared daggers at her friend. “Lemme go, or I’ll get myself out.”

Twilight was feeling very awkward as it dawned on her that she was essentially attacking one of her best friends, after foalnapping them. "Okay then, if you're the real Rainbow Dash, then answer me this-"

"Twilight Sparkle. I swear if you don't let me go right now I'll make it rain on and in this library for the next month. And you'll have your own personal snow cloud follow you for the entire winter," Rainbow threatened with a determined look.

"Okay, I'm sorry Rainbow. I guess I over reacted a little," Twilight said as she untied the ropes with no effort.

"A LITTLE? You tied me up, cast magic on me, accused me of being a changeling. What the flock is wrong with you?! Applejack said you can be jealous, but... this is going too far."

"Applejack said that? What else did she say? Did she say anything about me? Does she miss me? She must miss me, why else would she have you talk to me when she could have come to me! Applejack and I, we had a system and,” her eye twitched again as her mane became loose, “you don't have a system do you? You're impulsive and brash. I'm calm and rational. Logical, refined," Twilight said, standing taller, her nose in the air with and air of Canterlot pride and poise, "you are not. I am the better mate by default for anypony, mare or stallion, and you are not. Therefore, she misses me!"

"Twi, You're. Acting. Crazy! I'm outta here." Rainbow flew as fast as she could up the stairs and to the window she came in but couldn't get out of the library. "Twilight, open these windows or I'll break them out."

Twilight ran upstairs and looked at Rainbow Dash hovering high in the air with her forelegs crossed and a frown. "You want out, or... do you need to get out?" Twilight asked with an eerie grin.

"Both, now open up the way out, or else," Rainbow threatened.

"You want it, you need it, you got it." With a flash of her horn, Twilight cast her 'want it, need it' spell on herself. Seeing Twilight, Rainbow’s eyes rolled up into her head and hearts rolled to replace them. She practically fell to the floor, stopping just before and flying quickly to Twilight. She wrapped her forelegs and wings around Twilight, pulling her into a passionate kiss.

Twilight was expecting something, but not the sudden physical actions. Suddenly she felt herself becoming aroused as she laid back onto the floor under the pegasi’s weight. Rainbow climbed on top of Twilight and began kissing the base of her horn, down the sides of her head, cheeks, then slowly began to peck her way down Twilight’s neck.

Twilight’s eyes closed as she tried to cast a spell but couldn't focus through the erogenous spots being stimulated by Rainbow. Slowly, down Twilights body the kisses went.

The pleasure was as intense as anything she's learned to do to herself with magic over the course of her life. Losing herself in the moment she reveled in the feeling of her body being touched and kissed until Rainbow got to her teats and licked, sucked, and lightly bit a nipple. The sudden pleasurable sensation made Twilight giggle loudly.

"Rainbow, you're so good at this. Applejack is gonna be so jealous when she finds out what you're doing to me."

"I love you so much, Twilight. So much. I need you, only you," Rainbow said between kisses that lowered her to Twilight’s labia, "you're so delicious. You're so magical. I'm nothing without you. You're better than the princesses. Applejack can buck herself. You're all I need."

Sitting up enough so she could see the rainbow mane bouncing below her belly, just as she felt a nose tickling against her clot, Twilight looked at the mare offering her affections and shuddered. She only wants me? I know she's impulsive and reckless but, oh Celestia, this is too much. I have to stop this. I have to talk to her. "Rainbow, stop, can we talk?"

"Mmmphmh," Rainbow said as she darted her tongue inside Twilight.

Twilight yelped at the feeling of her insides being touched by a soft, wide, wiggling tongue. With a victorious chuckle, Rainbow did it again and again. Twilight’s heart raced a she arched her back slightly. The image of Applejack popped into her mind and she used her magic to push Rainbow back, then used her tail to cover her wet pussy. She rolled over, but Rainbow grabbed by the hips her and flipped her back, trying her best to move the tail and get more of Twilight’s juices.

"Rainbow, please, stop. STOP. Rainbow Dash. Stop!" Twilight began fighting as she pleaded the enchanted mare fought to please her. Focusing her magic she cast a dispel and her heart fell, realizing what she’d just done.

Rainbow stopped her assault and looked at Twilight abject fear and disgust as she scrambled back and away from the spell caster, backing into a bookshelf and knocking several down around her. Rainbow sat, guarding herself with her forelegs and wings reflexively.

"Rainbow, I'm sorry. I didn’t mean-"

Rainbow screamed in fear at Twilight as she flew out of the nearest window as fast as she could, tearing the blinds and shattering the glass as she went though.

Oh Celestia, what have I done? Twilight thought as the air settled and another book fell.
