Going inside the castle of friendship always gave a special feeling to Starlight. When occupied, it was a cozy place where she felt welcomed and loved. Spike constantly said to her that what she felt was calling "home" and that wherever she went, if she felt like that, that would be her home.

Now, the castle was empty, yet the feeling remained there, the tidiness remained, the fresh smell of wet wood remained, constant as if waiting for the opportunity to bloom once again. Or maybe that wish for blooming came from her, for she too desired to stay in her home as she used to in the past.

All those thoughts made her sigh slowly. "It was so easy to leave my real house, yet it's so hard to let go of you," she said smiling, since she knew that nothing was really lost. Things had changed a lot, but the core was still there, the new family she earned was still with her.

She moved forward, mindful of pleasing her senses with the sweet aroma left in the castle. Her strode became hopping as memories flooded her mind. Thoughts popped to the surface every so often; ideas of what to do the next time she and all her friends could see each other again.

Another door stood before her, the reason for her visit was most probably in that room. If that same reason listened to her this time. She went forward, the room receiving her with the view of row after row of bookshelf's, all filled to the brim with books and all organized. ¿Organized in which fashion? Well, that question has an interesting answer.

Twilight left an assortment of spells ready inside the castle, one of them, the babel's organizer, was a potent spell that made the people inside the library unconsciously know where to go. That's it if they knew the topic, name, or any other detail of the book.

"¡Trixie!" Starlight called, "¿¡Are you still here?!"

Her voice boomed through space, yet there was no answer, "Did you find the book?!"

A single book of pony kind's physiognomy, the subject for Trixie's next lesson. Finding it wouldn't be a problem for herself but Trixie wanted to take care of it herself. In fact, she found the book after a couple of minutes thanks to the Guiding Spell.

Looking at both sides of the corridor she found no trace of Trixie, whatsoever, she still believed that her friend was there. "¡I found the book!" she shouted.

"¡Eek!"

The pink fur on the mare's ear quivered as the appendices moved by themselves forward. She followed the direction of the sound, calling her friend's name over and over. With impatience growing stronger inside her she opted for other solutions.

"Okay, I'll find you then… just have to think like the great Trixie would do" Starlight boomed, "One that would enter this place, probably forgetting how it works. And so she thought, the book starts with p so let's search for that."

Her strode was constant and a certain vibe of joy could be noticed in every unnecessary jump she added to it. "¡But then the library will guide her to the things with p that she likes the most, like powerful spells!"

And so she found herself within seconds before the bookshelf she expected, "then, silly me I left my bag of snacks on the floor, surely twilight's magic will take care of it. Actually, it will do so at night. That doesn't mean is correct"

"Star-" She heard across the room.

Starlight took the empty bag with her magic and tossed it to the closest trash can before keeping her charade, "Now, as Trixie, I saw that those were really complex and weird spell and none of them were fancy enough for her majestic style."

Starlight's ear perked up, the tips of her hair eager to move at the slightest of sounds. Soon, another bookshelf stood before her, one with a book about illusion magic, self-improving, charismatic behaviors, and guides for lectures.

"I, Trixie," Starlight declared, "shall be an acquaintance of the way of proper teaching. My students deserve the best after all, and I shall remain as that." Her lips curled into a smug smile as she looked at her surrounding, confident of her skill and that her friend would be there…

"Starlight…" it was Trixie again, she was closer this time. "I-it's okay, y-you can… goh…"

Something was wrong with her voice.

"Trixie, are you alright?!" Starlight shouted to her right, "You sound weird." She waited for a moment. No answer. Following her previous action, she started to question herself about the other things that Trixie would do.

Trixie, face to face with an assortments of books that would make her a better magician, a better pony, a better teacher… all those changes for the sake of being better at the eyes of others… is not proper for Trixie, at least not like this.

"Trixie loves to be praised and wooed over her abilities and looks. For her to want to change…" Starlight thought out loud, and as if the spell could hear her concerns like a close friend, a new route was inserted into the mare's mind.

She blindly followed the path as her mind kept questioning the possibilities. To her surprise, the path led her to an unexpected bookshelf. This bookshelf was decorated with gems on the edges, and each book had a particular vibrant color ranging from white and gold, black and blue, white with pink, gold with purple, and a sole book of green cover with a purple stripe protecting the covers.

She took the lonesome book and read, "To love One Self, by Spike T. Dragon."

It clicked immediately, those books in front of them were made by royalty. A quick glimpse at the purple covers was enough to confirm, all of them had themes about Friendship, and all of them were made by Twilight herself.

She took a seat in front of the odd response that the library spell had given her. Why take her there of all places? She questioned. Then, she noticed an odd detail. One of the books was poorly placed. She took the book, "From Friendship to Love, by Cadence A."

A sudden, wild, assumption took a hold of her thoughts. From her own desire, to be appreciated by others, to be a better pony… a subject unkind to Trixie that already thinks herself as perfect. But what if she doesn't think she is perfect for someone else? In the eyes of someone else's. Then the question will be, who is that pony that is so important for the magician that she is willing to change?

But this was not anypony, this was a friend of hers, and because of it, she started to question the meaning of that desire, which led her to this same shelf. "Trixie… ?" Starlight called. She knew the odds were at her favor, Trixie has only two close friends, and one of them is already taken...

Which means…

"Trixie, I need to talk to you," She called again, heat and blood rising to her head. No answer. "Trixie, I found the book, the one written by Cadence. You were the last one to enter, and I know how the library operates, it only cleans and organizes the place after everyone is out. I know you read that book be-"

"S-Star… can we~ talk abo- it later?"

Trixie's voice was ragged and soft as if she couldn't breathe properly. "Trixie, you sound really bad, please tell me where you are."

Silence followed, and Starlight was not the one to wait for too long. She moved through the maze of books and knowledge. Kites, thesis about spells combination, reality-bending magic, better recipes for cakes. The brainstorm inside her head made, for briefs minutes, a living maze out of the library.

Of course, the sudden behavior of the spell didn't pass unnoticed by the talented mare, rather than that, it was welcomed with a grin of joy. She kept rambling thoughts inside her head, anything that could pop out she transformed it into a question for the spell to answer, and so the library became her playground.

Brown, black, red, and other colors swung past her, shelves and books of any size shape and form moved around her in a frantic way, as if every object inside the library was a train mounted on Discord's handmade rails.

"Staaarlight?!"

She heard her friend's voice, yet her mind was slow to stop the storm or was it that she started to like the mess she was making with the spell.

"Make it StoooOOOoooP!"

She followed the sound, mindful to not get hit by accident. After two more rows, she finally found her friend. Trixie, who was currently holding the back of a sofa with her whole body, waved a shaking hoof to her.

"Ahm… C-could y-you stop whatever you are doing with the room?"

Starlight then proceeded to make one of the shelves turn and push Trixie and the sofa towards her. Yes, she now liked to make a playground of the Library.

The force of the push made Trixie's grip on the sofa crumble. Luckily, catching her in midair was no feat for Starlight. After catching her, she was about to put her back on her hooves, but Trixie interrupted.

"Starlight, please, wait," she said, her body still midair and her back in front of Starlight's point of view. "Ahm, I made a really huge mistake. The effect will pass soon, so please just don't look at me, okay?"

Starlight sighed, her smile ever-present, "Come on Trixie, I have been through a lot in that department, I'm sure there is nothing to worry about. Just let me help you so we can talk."

Thanks to her long neck, Trixie was able to turn her head back enough to see Starlight. Her face was glistening in red and her eyes watery, yet it didn't seem for Starlight that she had been crying. "Trixie is still unsure about this… but I trust you. Just be mindful of your laughs once you see it."

"Oh come on it can't be that…" Starlight had just turn around the body of her friend, exposing Trixie's front, hooves and… "uhm… uh? Trixie, what kind of spell…"

The magician didn't have the strength to speak this time, instead, she used her magic and extracted a book from beneath the sofa. Starlight greeted the book with an intriguing look on her eyes, it was a notebook of brown leather cover and no title. She peeked at the page marked by the purple bookmark hanging on the top and read the page.

Upon reading the first words her face eyes grew in size and astonishment, "this can't be… This is Spike's… He wrote this!?" Upon further inspection she concluded that the little drake couldn't write the content of that page by himself, "Only Twi is good enough for… no. I don't need to know anything else.

"Trixie thinks that Twilight used it with S-"

"Don't! Just let's pretend we didn't find thi… Wait do you mean on Spike, right?!"

"The note's said Spike liked its taste-"

Starlight interrupted by throwing the book across the room with enough force to break the sound barrier. "Let's just pretend we don't know anything about this more than how to fix it, okay?"

Trixie nodded and then turned her attention to the real problem.

Starlight stared at the problem too… the big and meaty problem that had taken the place of Trixie's marehood; a puffin and erect member that only a stud of a stallion could bare.

Starlight gulped, "So… the spell will last until that… thing, gets calmed down."

"Yes, but it's been half an hour and still like that…" Trixie said, her eyes now focused on her friend. Her member suddenly twitched, "it was stubborn at first but now…"

Trixie's eyes glistened the more she looked at Starlight, "now it feels… weird-" The magic force holding her in midair had just moved her back to the sofa at the end of the hall, "Woah! Be careful, this thing is quite sensitive."

Starlight moved closer to her friend, her eyes fidgeting between Trixie and the hard member between her legs. "I don't understand, how did this happen?"

Trixie was resilient at first, but there was something on how her dear friend was looking her that eased out her thoughts, "well, after Trixie discovered the books you found, she thought that maybe there could be a spell who helped me get closer to you. Then that book appeared, I read it, did some things and now my…" she paused, her attention on the mare watching at her new throbbing member, "turned into this… this is my first time seeing one, hehe…" she quivered, "is your too?"

Starlight denied with a gesture, "I met a lot of ponies before and during my days as a villain. Never managed to feel something real for anyone though. What brings me to the question, "her face finally moved upwards, "Trixie, you… love me?"

"Eek! Trixie was just curious, don't think about it too much!" she then proceeded to laugh, her mouth and body shaking. Starlight moved closer and got up on the sofa with her, face to face, her fur unintentionally caring Trixie's new rod. "uhm, careful there."

"So, it was just a thought?" Trixie's red face moved frantically in approval. "Well… I had several thoughts too after finding those books."

"R-really" she breathed, "w-which ones?"

"Well, that, maybe…" she pressed her body towards her, making of Trixie a shivering mess, "no, it doesn't matter. Let's get rid of this spell first."

Trixie's color lost two shades in that moment, "oh… yeah, but how?"

"Is something that only really close friends can do," she said, their muzzles barely touching "ready?"

"Uh… ye-"

Starlight pressed her lips against Trixie's. The warm and soft flesh of her friend's mouth was overwhelming enough to make Trixie let a little moan upon touch. Starlight tried again, this time going rougher, pushing deeper. Trixie's moans couldn't stop the advance of her friend this time, as her mouth was slowly pushed into submission.

However, with all the previous restrain, it was not a surprise for Starlight when her friend took her in a tight hug. Was what a surprise was the look on Trixie's face after she released her from the kiss: the droll lingering in her muzzle, the flustered cheeks, the half lidded eyes irradiating joy and lust.

"More…" Trixie pleaded.

Starlight smirked at the sentence, and unable to withstand her own desire, threw her whole body towards her new close friend, making them both and the sofa fall to the ground. The fall didn't stop her advances, as their mouths and tongues collided in the second round.

Trixie's barely could move her body at will, the immense pleasure building up in her new member proving too much for herself. Yet her body seemed to move just fine by its own, as long as it could push itself towards Starlight silk like fur.

Unknown to the magician, each thrust of her hips made her balls caress the under lips of her friend, being this the reason behind Starlight's moaning throughout the sloppy make-out session. In response, Starlight moved her hips upwards, and rub her moist clit against the pulsing member.

Trixie tried to withstand it at first, but then the second thrust came, and with it went the air left on her lungs. She opened her mouth and let Starlight do the work while she recovered her breath.

Then the third shove came, and her whole body shivered once again. Then the fourth and so on, each one faster than the previous one, each one pushing Trixie's mind deep into the void of pleasure.

But then, starlight stopped and sat on her friend's member. Trixie moaned in discontent a "Why did you stop?!"

"If we are doing this, we'll do it all the way," she then stood up and turned her back to Trixie, her tail moved to the side, giving Trixie's a full view of Starlight's rump. "I hope you'll know what to do."

Driven by her lust, Trixie managed to get herself up. Her eyes stuck on that sweet and round pink rump. The glistening fluids drenching Starlight's fur made Trixie heart and eyes throb hysterically.

Even when it was her first time, she found herself not lost on what to do next. To mount her friend and push her dick so deep inside her marehood… the only thought made her moan and twitch.

Now, actually doing it gave the magician an unexpected outcome. Once she mounted her, the warmth of her friend led her to a drug-like state. "Starlight… you are so soft, ah~ and so warm…" She then pushed the tip of her dick, "Oh~ jeez…" the tension and throbbing on her member just increased as she pushed forward, and as she heard Starlight voice whimper and moan.

"This… I-" the buildup was too much, she couldn't feel her legs, body or mind… only the strength of her member erupting inside Starlight, "ah~" she moved slowly, and in out by mere inches.

Both Starlight and Trixie's ears twitched during the orgasm, even thou only one of the two had reached it. Trixie's member kept flushing its content inside the mare for a couple of seconds.

"That… aww.. that's a lot…" Starlight said as her insides began to stretch.

"Trixie feels sorry for peeing inside Starlight," That innocent sentence made it impossible for Starlight to not laugh, "Hey, what is so funny?"

"That's called an orgasm Trixie, and… oh~ you are still pumping it~" She breathed, cum leaking outside and into the couch's leather, "The white stuff is called semen, and the thing you just did is called cumming."

Trixie's breathing became ragged and slow, her climax had consumed most of her energy. The good news overall was that the spell had run out of energy too and now her member was returning to its back normal self.

While the process of change was taking place the tired magician couldn't stop herself from falling to the couch. Starlight breathed in, pleased yet still yearning for her own climax; she sat on her chest and went to her friend, giving her a peck on her forehead.

"It seems like someone loved that spell after all," Trixie nodded with a blissful grin on her face, "such a shame it didn't last enough…"

"Why?"

"Well, you were the only one cumming."

"What?!" Trixie turned around and sat on her chest, "I thought you…" Starlight differed, "goodness… and here I was enjoying it all by myself. I'm so sorry Starlight, I-"

Starlight took Trixie into another kiss session. The magician was impressed if not confused at first, but her thoughts dimmed as her friend's tongue rolled inside her mouth. Both of them moved closer, their mouths munching the other's lips with each breath. Trixie started to notice then that even when her parts were back to normal, an abnormal warm was washing over her nether regions.

Starlight pushed her friend through the sloppy make-out until she found herself on top of her friend. The fur on their chest quivered at the constant caressing made from the exchange. It seemed for Trixie that they had been doing it for an hour, yet it had only been a couple of minutes since the taste of Starlight clouded her mind.

This perception of time was nothing but her own desire extending the definition of time for her own pleasure. Of course, she wasn't aware of it, the only thing she was aware of what the smell of her friend, her soft touch the warmth fogging her mind and body.

Unfortunately, Starlight parted from the kiss but gave Trixie a sweet little peck on the lips before doing so.

"Uh… why… why did you stop? Trixie loves this!"

Starlight had to cover her mouth to stop herself for laughing too much, "You look so cute when you said that. It really makes me want to spoil you more," she said before nudging their muzzles together, "Let's take a snuggle break."

"Snuggle break?"

"That's how Spike called them," she said before falling to Trixie said and hug her, "I just want to talk a little before we continue."

"Okay, but first…" Trixie's voice turned shy and soft, "this snuggle break is something like really close friends do too?"

"Hmm? Oh, no, no. Spike was not as close as you are, and even if I wanted him to do so, Twilight wouldn't let me." Upon hearing this Trixie whispered a sigh of relief. "You know, close friends usually share."

"What!? No!" Trixie's cheeks had turned red enough to disguise her as a tomato, "I'll treasure your place as my only close friend!"

Starlight couldn't stop herself from bursting in laugh this time. "Oh my Celestia, you are so cute," she continued giggling, much to Trixie's shame.

"Trixie doesn't know why are laughing so much, this is serious!" Starlight laughs then dimmed. "Now you, uh… ?" tears started to flow out, "why are you."

Smiling, Starlight held close her friend in a tight hug. "This, ever since they left I have felt so alone. I needed a family, someone to be there for me. Someone I could be with and call it home. Trixie, if you really want to be my only close friend… then I don't see a problem if you are my marefriend."

…

Trixie surrounded her friend with her hooves, taking her too into a tight hug.

"To be honest. There are times that we disagree, times when I can't even stand you… but then there are times like this: when I don't want you to let go of me, so we can be together foreve-"

"Shut up!" Trixie shouted, her eyes tearing apart, "you are making Trixie cry! Trixie wants smooches, not tears! Trixie will make the perfect marefriend for Starlight!"

Starlight giggled at her new marefriend outburst but found no problem giving in to her demands, and so, she took her into another kiss and pinned her to the couch.

The spell had long disappeared and now Trixie marehood was the one eager to continue the job her previous form couldn't finish. However, she wasn't ready for the staggering feeling rushing through her upon the first shove. When both mare clit and labia caressed each other the thunder-like wave of pleasure struck Trixie's body and inner thoughts made her release herself from the kiss with a powerful shriek.

"Seems like you are new in this department too," Starlight smirked while still pushing her friend's hips towards her. Making Trixie's moan and droll to her heart's contempt.

"T-trixie, this ah~ this feels oh! Much better than hooves!"

Starlight was more eager to continue with full force than Trixie since she didn't have her own end in their first round, so being slow with her new marefriend was a hard task for her. But even in that state and with all that power over Trixie, she knew that Trixie would end up coming again soon at that rate.

Nothing a little magic couldn't help. Starlight made a rod out of her own magic and wasted no time in using it. Now with her insides and her clit being messed around at the same time properly she succumbed into her own instincts and started to moan in ecstasy. The gasping sound of the pink mare was music for Trixie, who in response couldn't help herself but look down and appreciate the blissful expression of her marefriend being unfold to her like a new piece of art.

"Starlight…" she sang in her frenzy state, "I'm close… please tell me you are too."

Starlight responded at first by increasing her speed, "yes, I am ah- please…" she took Trixie by the neck, "kiss me."

Trixie was not the one to reproach such wish, and so she vigorously took her marefriend in one last kiss, caressing her neck and chest while doing, feeling the heat inside her oven burn her thoughts to a crisp. Everything left from both mares was the feral sounds of her instincts playing out as their bodies shrieked and their marehoods convulsed in pure joy, Trixie realizing first with spirit in her voice.

"Oh, Star~"

Starlight by her part was taking such a hard time for resisting the pleasure of her climax that she could barely open her mouth, yet no sound came out beside a silent gasp.

They remained there for a while twitching ever so slightly to relish on the remnants of their own afterglow. Trixie fell on her loved one afterwards, her breathing slow and deep.

"That was…"

"I know…"

They rolled over, their smiles just mere inches away from one another. Caressing themselves, giving and taking little kisses here and there. The library was no such a place for the things they did, but surely their home was…

And for Starlight, she was more than sure that she was in her home.

"Trixie wants to stay like this all day," she said before snickering and giving another kiss to her marefriend cheek.

"Me too… but we both know that we'll get in trouble if we stay here and don't clean all this mess," Starlight remarked with shyness tainting her face, the couch really needed a proper cleaning after their doings.

"Okay… but, can we stay here a little longer?" Starlight nodded, "thanks, Trixie really wants to treasure this moment."

"Don't worry, there be plenty more of these," Starlight then kissed Trixie on the lips, "but just so you know, next time I'm the one using that spell."

"I thought you didn't want to know anything else from that book."

"Nono, I only don't want to know anything more about Twilight and Spike regarding that book."

Both mares chuckled at that comment for a while before returning to the sweet session of loving stares, "You know something, Trixie?" Trixie then tilted her head to the side, "you always find a way to make spell turn into accidents. Most of the time they made me laugh, but this time…"

Trixie smiled at her, maybe because she could already feel the energy behind Starlight's words.

"This time I really loved your little accident."

"Correction, Trixie's big and powerful accident."
