Trixie wants Starlight to teach her a dick spell, but Starlight insists it's too advanced for her, so the showmare decides to look it up on her own. And she finds it...! but the result isn't exactly what she expected...

Trixie has been learning spells from her very dear friend Starlight lately, and has been making great strides in her magical compendium. However, during one of their nights together, Starlight refuses to teach her a spell that Trixie has taken a fancy to. This doesn't sit well to the showmare, so she decides to learn the spell on her own, but the result seems a bit different than what she expected...

Contains: Futanari spells, blowjobs, and a very healthy cumshot. I'll update this list when I write more chapters.

"Doing the Spell...!"

"Oh, come on! Why not?” Trixie asked exasperatedly, lying on her side of the bed.

“Because it’s really dangerous! Before you can cast these kinds of spells, you have to master more basic magic, Trixie,” Starlight Glimmer explained.

"But I already know how to do similar spells!" Trixie raised her hands in an indignant gesture. “I can turn whatever I want into teacups!”

Starlight sighed exasperatedly and rolled her eyes for a moment. "What you're asking me to teach you is much more complicated than transforming one inert object into another."

"But I want one just like yours!" Trixie lifted the bed covers in one quick motion, exposing Starlight's naked body. Then she pointed to his groin. “Damn, I still can't believe how big it looks.”

From Starlight's crotch dangled an impressive cock a shade darker than her pink fur. Although it wasn't as impressive as when Trixie had seen it a few minutes before, fully erect.

The two ponies hadn't known each other for a long time, but it didn't take long for them to become close friends. Interestingly enough, and although they weren't aware of it at first, Twilight Sparkle was the main reason they both hit it off when they met. And it wasn't because Twilight was a mutual friend, no. In fact, even though Starlight had become a close friend of the Princess of Friendship, Trixie and Twilight didn't seem to get along very well. No, it was more because of the villainous past that they both abandoned because of Twilight and that they wanted to redeem themselves from.

It was precisely because of this common past that Twilight, as Starlight's mentor, initially didn’t approve the friendship between the two, although over time she ended up accepting it. At the end of the day, friendships were something personal, and Trixie had shown that she truly had changed and that she was sorry for her bad actions.

That friendship between Trixie and Starlight built up their trust enough so, at a certain point, they started having sex sessions from time to time to have a little fun. In Equestria it wasn't too unusual to have relationships like this openly to have a good time or relieve some stress.

That evening was one of those where Starlight decided to draw out a new sex spell from her oddly vast repertoire. Trixie didn't expect to see her friend with a huge cock between her legs, but the surprise was more than welcome, of course. She still felt sore from the tremendous fucking she had received from Starlight, but she didn't regret it for a single second.

"It's not that big," Starlight replied. “It's just that it looks proportionally bigger in a mare.”

"What are you saying, babe? It’s bigger than my fucking forearm!" Trixie lifted her friend's dick with one hand and put her own arm next to it to make her point, however, the member didn't surpass it by a few inches. “Well, it was bigger when it was hard.”

Starlight gently pushed her friend back to regain her personal space.

"Look, Trixie, if you want one just like mine, all you have to do is ask for it. I can cast the spell on you.”

“No!”

Starlight was confused by her friend's indignant denial. “No?”

"I want to cast it myself!" Trixie snapped. “What's the point of you casting it again? I'm the one who wants to learn how to conjure it!”

"Okay, I understand that, but I thought…" Starlight paused for a moment. “Look, if you want, one of these days I can teach you more basic and potentially less dangerous transfiguration spells. Over time we can get into morphobiological transfiguration spells and then we’ll raise the level step by step until I can teach you the spell you want.”

The pout on Trixie's face hadn't softened one bit. If there was one thing she hated, it was having her wishes interfered with, especially when they seemed so simple. Why couldn’t Starlight just teach her the spell she wanted? She had already advanced a lot with her lessons! Like, she was able to teleport stuff with her magic and such! Although it’s true that they didn’t always end up where she wanted, but that was a minor detail.

"And how long will I have to wait before you teach me how to conjure a dick?" Trixie asked.

"Well, if you're diligent enough, maybe in… a few months."

“Months?”

“-Umm, yes. Maybe about…” Starlight paused to do some mental math. “Six or seven?”

“What?” Trixie let out a frustrated sigh. “You must be kidding, right? Do I really have to wait that long to conjure up a cock like yours?”

“No, no.”

"Ah, that’s good. For a moment I thought…”

"Conjuring one like mine could take you even longer. Years, even,” Starlight explained. “It’ll be smaller at first - much smaller, probably. As you gain experience with the spell you’ll be able to increase its size.”

“What the…! Years?!” Trixie rubbed a hand over her face and tried to calm her tone. “Starlight, are you telling me that you've been practicing a spell that gives you a dick for years?”

Starlight giggled awkwardly and looked away as she scratched her head. "Well, what can I say? I was a very curious filly back in my time."

Frustrated, Trixie dropped her body back onto the bed. "You just crushed my mood."

"Oh, don't be like that." Starlight's horn lit up with a faint blue light. “Are you sure you don't want me to cast it on you? Seeing what you can achieve if you work hard enough could raise your spirits.”

Trixie looked at Starlight's glowing horn without raising her head from the pillow. Then she looked down at her friend’s huge member and, after pondering for a moment, she sighed and turned her back on Starlight. “No. I don't feel like it right now.”

"Oh…" Starlight turned off her horn and a look of disappointment formed on her face. “Okay, but if you really want me to teach you how to master that and other morphobiological transfiguration spells, it’s mandatory to teach you all the corresponding lessons first for safety. You know the saying: you have to learn to walk before running.“ She showed a friendly smile. “Tomorrow I'm going to the Crystal Empire for a couple of days, but as soon as I get back we can get on with it. How about that?”

Trixie let out a groan. Knowing that she needed to learn so much stuff before the spell she wanted didn't make her exactly happy.

"Okay, I'll think about it," she said angrily, back still turned on her partner.

"I'll settle for that," Starlight replied with a wide smile. “You’re gonna have so much fun! There are many interesting spells!”

"Yay…" Trixie replied wryly as she raised a fist and then slammed it back onto the bed.

Starlight lay down on the bed again and covered herself with the sheets while she made herself comfortable. "Well, I'm going to sleep now. It's late and tomorrow I have a very long day ahead of me. Good night Trixie.” Her horn lit up for an instant and she turned off the lights in the room.

"Good night…" Trixie answered reluctantly.

The truth is that Trixie wasn’t looking forward to Starlight's classes too much. Although in general the magic practices could be fun, the theoretical parts were, on the contrary, incredibly tedious. And the theoretical part always was first. Why didn't she just teach her the spell and that's it? It couldn't be that difficult, right? What's more, she was sure… Hmm… She was sure she wouldn't have much trouble finding it in the library.

That's it - the castle had a huge library! Twilight and the rest of her friends were also out on a Map of Harmony mission, so tomorrow she was going to be alone and could search for the spell without interruptions. It was the perfect moment!

Trixie smiled. She was going to show her friend that the Great and Powerful Trixie could easily master any spell she wanted, no matter how complicated it was.

Trixie wasn't exactly an early riser, but she made a little effort and got up early the next day to escort Starlight to the Ponyville station and help carry her luggage.

It was as she got up to go to the castle's kitchen to prepare some tea that she realized something: Apparently, the Forgetful and Clueless Trixie hadn't realize that Spike was also in the castle. Twilight Sparkle's young helper had already set to work in the kitchen and was cooking the breakfast for the three of them.

Trixie growled to herself. She didn't expect the little guy to be there. Spike was rarely apart from Twilight, so she thought that he would’ve gone with her on their mission. Now she wouldn’t be able to check the library without having the little dragon’s eyes upon her. Frustrated, she ate a double helping of the caramel waffles Spike had cooked, leaving the dragon without his part. Ha ~ that’ll show him! He, however, didn’t care at all and went with a smile to cook more. It wasn't the reaction she expected, but at least the extra helping had sated her appetite.

When they finished breakfast, Starlight and Trixie packed their bags and headed for the train station. Once there, the two friends said goodbye, but not before Starlight insisted on Trixie staying out of trouble. The nerve! She was only going to be alone for two days! What kind of problem would she be able to cause? Of course, at her time, it only took her a few hours to bring down all of Ponyville and conquer the town. But that was water under the bridge. The Humble and Repentant Trixie would never do such a thing again!

Starlight probably wasn't referring to something so dramatic, but still, Trixie grudgingly assured her that nothing was going to happen and that she would be on her best behavior.

Once the train left for the Crystal Empire, Trixie returned to the Castle of Friendship. The huge building was still officially serving as the town’s library since the town hall hadn’t yet enabled any other premises for it, so the castle was open to the public at certain times of the day to cover that need - not a very pressing need, on the other hand, since it hardly received any visitor. Still, it was yet too early, so Trixie had to ring the bell for Spike to open the door.

"Hello again, Trixie," said the dragon after seeing the unicorn. “Have you forgotten something? I thought you'd go back to your caravan after escorting Starlight.”

Although at first Trixie didn’t expect the presence of the dragon, during her walk back she thought the perfect excuse to not raise any suspicions and be able to look for the spell she wanted. What a smart pony she was!

"Hello, Spike. The Great and Powerful Trixie needs new tricks to spice up her shows, so I'd like to take a look at the library,” Trixie commented brashly. “I'm sure there’ll be some interesting spells among some of the old, musty tomes you have.”

Spike narrowed his eyes suspiciously. "The library is closed right now and I have to go out and do some shopping," he said dryly. “Also, I don't think it’s a good idea leaving you unsupervised in the spell section…”

“What? It'll only be for a little while, Spike.” Trixie tapped the dragon's head. “I’m not doing anything bad, I promise. I'm just going to get ideas for some new magic tricks. Besides, I know you like them a lot!”

Spike stared at Trixie. She smiled from ear to ear upon seeing the inquisitive look of the dragon, trying to show the most innocent face possible.

"The waffles were amazing, by the way," Trixie added. “You are quite the chef, Spike.”

After holding her gaze for a while longer, Spike finally cut it off and sighed. “Okay, fine. But please, don't get into any trouble nor tell anyone that I left you alone in the library. Twilight will kill me if she finds out.” Spike opened the door wide to let her through.

Yes! The Great and Powerful Trixie wins again!

“Thank you!” Trixie lowered her head to Spike's and gave him a small kiss on the cheek, making the little dragon blush. “I promise you won’t regret it.”

"I-I hope so..."

The truth was that, for Ponyville being such a small town, the library it housed was really impressive. In a way it made sense that a castle as big as the one Twilight, Spike and Starlight lived in would hold a likewise big library within its premises, but Trixie couldn't help but drop her jaw when she first saw it. Luckily, thanks to Twilight's pet peeves and Spike's hard work, almost any time you went the bookshelves were neatly organized, so if you were looking for a particular book, finding it would only take a minute.

However, there was nothing of the subject she was looking for - nothing at all.

How was that possible? Yes, there was a spell section in the library, obviously; it was expected considering that Twilight and Starlight were avid readers of that particular topic. There were also several books on transfiguration, but very few of them dealt with spells applicable to living beings, and absolutely none of them had what Trixie was looking for.

After fifteen minutes of researching, Spike appeared in the room to say goodbye and left to do the shopping just as he had said, but not before imploring her again not to do anything weird or dangerous. Sighing and rolling her eyes, Trixie assured him that it would be fine. For a moment she was tempted to ask him about what she was actually looking for, but she didn't want to let the cat out of the bag, so she decided not to.

Once Spike was gone, Trixie decided to search on other sections of the library. Maybe there was something in the biology section that could suit her interests. While she was going through a couple of bookshelves to go to the area she was looking for, she noticed something curious out of the corner of her eye: a sign that said “no trespassing without authorization” hanging from a door.

Trixie had already been at that library several times, although she was always with company, so she had never had the opportunity to snoop around. That door never caught her attention, but now it actually did because of that sign.

Now, however, she was alone, so, with a smile on her face, she decided it was time to satiate her urge to pry. She went to the door, turned the knob and pushed. To Trixie's surprise, it was open. Usually, the rooms that have sensitive material were left closed, and more so in places that were open to the public. Surely Spike had forgotten to close it before he left, or he was counting on closing it when he got back. In any case, Trixie entered the room. It didn't seem to have any windows, so it was dark as a timberwolf’s mouth. She flipped on the light switch, which was next to the door.

The room was relatively small, about a hundred feet square. There was just a wooden table in the center with a couple of chairs, and several bookshelves built into the wooden walls. Curiously, in this section the shelves were half empty. Surely Twilight didn't have that many books under her belt that she wanted to keep out of the general public. Trixie walked over to the bookcase closest to her and read the title of one of the books.

“‘How to boost your libido. Spells and natural remedies.’"

Jackpot! Yeah, it wasn't exactly what she was looking for (the Great and Powerful Trixie was a pony with an exceptional libido, thank you very much), but seeing what she had in her hands, it was clear that Twilight kept the racy books there, out of the public eye. Oh, Twilight, what a rascal you are.

Trixie left the tome in its place and searched the shelves conscientiously for something that might serve her penile intentions. There weren't too many books, but she was certainly close to what she wanted. Aha! "Sexual Transfiguration Spells"; Trixie was sure that she’d find something there. She took the book from the shelf and opened it at the index. Wow! There was a lot of stuff there! Lubricant spells, sexual enhancers, contraceptives, breast enlargement... There was even one to change your sex completely! Trixie was sure that several of those spells had been used by Starlight during her intimate moments with her. At least she already knew where she had gotten her repertoire from. And within that index… “Conjuring male genitalia on a mare” Exactly what she was looking for! She looked at the page in the index and went without waiting any longer to the spell page.

The first thing she came across were several pages of contraindications and failsafes to dispel the spell. Unfortunately, she barely understood what she was reading. The text used advanced terms that Trixie had never heard of. Well, maybe she could go straight to the spell itself. She flipped through several more pages until she got to the interesting part… but unfortunately for her, it was even harder to understand. There were graphs, tables, formulas, and even more complicated terms than in the counterspell section.

Trixie let out an exasperated moan and slammed the book shut. Why did it have to be so difficult? She just wanted a fucking dick, for Celestia's sake! Grumbling, she put the book back where it was. However, she wasn’t going to give up so easily; there were still many volumes to review. There had to be an easier way to conjure up a good, hefty cock, and she was sure it'd be among those books.

Several more minutes passed that Trixie used to scan each of the shelves from top to bottom, until in one of them she found a black book with red letters that caught her attention. “Daemonium Sexus Incantamenta”. Trixie knew enough about Pony Antiqua to figure out the title. "Demon sex spells"... Pffft, yeah, yeah, sure. She rolled her eyes. The author was probably just trying to be edgy, but it wasn't like she had much of a choice, so she picked up the book and opened it. It was quite worn, with very yellowed pages and some of them torn at the edges. She almost expected to kick up a cloud of dust from the book to fulfill all the clichés, but it seemed that Twilight kept all her tomes clean, even the ones away from the public. It was written in what appeared to be red ink, but it was quite dark, probably due to its antiquity.

Trixie flipped through the volume quickly until a drawing caught her eye. It was a diagram of a stud's huge cock protruding from a distinctly female pelvis. “Equa Penis Dilatatio” Great! That could be what she was looking for! Trixie tried to read the notes that accompanied the diagram. Her Pony Antiqua from when she went to school was a bit rusty, but, as far as it went, the spell didn't seem to be too difficult. The only strange requirement was to draw an enchantment circle on the ground and stand in it while she cast the spell on herself. Easy peasy! The circle was quite intricate and full of details, but nothing she couldn't replicate with a bit of patience. At last, she was about to get what she wanted!

Trixie looked at the drawing in the book, then at the circle she had chalked on the floor. Her sight switched from one to another, again and again. She showed a wide smile; the circle was exactly the same as the one in the book. Perfect! She would have to scrub the floor to remove it after that, but it would be a small price to pay if the spell was effective. Still smiling with excitement, Trixie began to undress; she wanted to see directly the effect that the spell was going to have on her. T-shirt, shorts, underwear... she left each of her garments stretched out on the table. Now completely naked, with all her clean, blue fur in full view, Trixie stepped on the circle and picked up the black book by the spell page as she read it quietly, trying to memorize it. Okay, she was ready! Trixie put the book down on the table and returned to the circle.

The mare relaxed and she closed her eyes while trying to concentrate. Frowning, her horn lit up with a faint lilac light. Said light gradually expanded around her body, until it was focused on her crotch. Suddenly, the lilac hue changed to a deep, bubbly black with hints of green. A violet vapor began to ooze from the outside of her eyes, like a pair of poisonous tongues. The circle on the ground glowed and black tentacles appeared around her, reaching out and stretching until they reached the mare's pubis. Startled by the pressure she felt from those sooty tendrils, Trixie snapped open her eyes, which glowed with a green light so bright that her irises weren't even visible. At this point, Trixie's magic continued to channel intensely into her crotch almost instinctively. Even if she had wanted to stop the spell, there was no going back now. The blackish appendages, already attached to Trixie, coiled like a black hole, twisting and pulsing into a cylindrical shape.

Despite the disturbing shapes and colors that she was seeing, the process of that spell wasn't being painful for Trixie. Quite the opposite: that magic was making her feel a really nice tingle, especially in her groin. It really didn't seem too different from what she felt while masturbating.

Suddenly, just as the cylinder in her crotch seemed to begin to take on a more detailed shape, a pillar of intense black light erupted from the circle, engulfing Trixie completely like a blast, lifting Trixie's mane and tail in an energetic gale. Everything was black for the unicorn, until, after a few seconds, the wind stopped and she regained her vision. Her horn was no longer channeling anything, and the black tentacles were gone. Even any trace of the circle she had drawn had vanished.

"Wow…" Trixie blinked a few times. “That was... weird.”

Without waiting any longer, she looked down, excited to see what she was going to find.

“Fuck yeah!” Trixie pumped their fists, gesturing with satisfaction. “It worked!”

Between her legs was a completely stiff, throbbing stallion's cock, a shade of blue slightly darker than her fur and about eight inches long. It looked a lot bigger on the diagram, but the size of what was down there wasn’t exactly small either. It was far from the footlong Starlight was able to conjure, but it wasn't bad at all for her first time.

Trixie wrapped a hand around the swollen member and shivered at the contact. That thing was really sensitive. She put another hand under his cock and felt for the scrotal sac that she now had. They were a good size, like plums, but nothing close to Starlight's huge balls. Still, she was very happy with the result.

"Trixie? I'm back. Are you still around?”

Oh shit.

Spike's voice came from the other side of the door, in the main room of the library. Trixie had closed the door to the room she was in just in case, but she didn't have the key for the lock, so the dragon could come in anytime if he wanted to.

Shit, shit, shit…

Trixie dressed quickly, putting on her panties, bra, t-shirt and shorts.

oh fucking fuck…

Unfortunately, she didn't expect that by casting the spell, the resulting erection would be hard to hide. There was a distinct bulge in Trixie's pants, as if she was trying to hide a good-sized cucumber under them. The unicorn tried to move the big bump in every possible way while she made faces at how sensitive her new tool was, but it was useless; she couldn't hide the bulge at all. Why on Equestria would she think of wearing pants so short that day?

Trixie searched around nervously for something she could use to hide the bulge, whatever it was. She only saw books.

Well, after all, the excuse she had come with was that, so…

She tried to listen carefully for any noise on the other side of the door, but heard nothing. Possibly Spike would’ve left when he saw that she wasn't in the main room of the library, since the room Trixie was in right now was supposed to be locked, so she shouldn't have been able to get in. Making as little noise as possible, Trixie placed everything in the forbidden room as it was before she entered, black book included. She then carefully opened the door, returned to the main room of the library and closed the door through which she had left. She now only had to pick up a couple of books; she walked over to a bookshelf quickly, picked two volumes at random and placed them against her crotch, holding them up as if she was a shy student. A posture not typical of her uninhibited personality, but at least she could cover her bulge that way.

When she thought she was ready, Trixie walked out the library. She was going to go to the entrance, but as soon as she went out into the wide corridor of the castle she saw how Spike came out through another of the doors. If Trixie's memory served, the little dragon had come out from the kitchen.

"Oh, I thought you left already." Spike looked at the books Trixie was holding. “Were you still in the library? I haven't seen you before.”

Trixie quickly thought of an excuse.

"I-I was in the bathroom." She gestured at the books she had against her crotch. “I’m going to keep these two books. I’ll return them as soon as I can.”

"Very well," Spike replied. He then indicated the books with one hand. “Can you give them to me for a moment so I write their names down?”

If she gave them to Spike now, the bulge in her crotch would be visible. In fact, as short as the dragon was, he would be eye level with it, and she couldn't allow that.

"Oh, surely that's not necessary, is it?" Trixie replied with a nervous smile. “I-It's just a couple of books.”

Spike, however, didn't seem very happy with what she was proposing.

"Trixie, I have to write down all the books that come out from the library. No exceptions," he said with a serious expression as he put his hands on his hips. “It's bad enough that I left you alone in the library. If Twilight finds out that there are books absent and not listed (and trust me, she'd find out sooner rather than later), she's going to give me shit for days.”

Trixie tried to make up some excuse, but she couldn't think of anything, so she was going to have to give up. Fortunately, she had picked up two books for a reason.

“Okay, okay. I understand.”

"Good, let's go to the library then," Spike said, pointing to the door behind Trixie. “I have the list of book loans there.”

Trixie turned to go back into the library. Spike followed her and went to a desk with a chair at the back of the room. He jumped onto it and opened one of the drawers to pull out a notebook. Then he waved his hand for her to pass him the books.

Trixie walked over to the desk and placed one of the books on the desk while pressing the other firmly against her groin.

Spike, seeing the title of the book, raised an eyebrow.

“‘Botanical Studies of Coniferous Plants, Volume 3’? I thought you were looking for spells for your shows.”

A bead of sweat trickled down Trixie's forehead. She was so desperate to find a couple of books to cover herself that she hadn't even noticed the ones she'd picked up.

"Oh, yes, yes, but this is...something else," Trixie said nervously. “I love conifer trees! I am a true fan of pines and their pinecones, hahaha…”

Spike shrugged and jotted down the details of the book in his notebook. Next, Trixie picked up the book from the desk and put it back against her crotch as she quickly pulled the other out and placed it on the counter, smiling awkwardly.

The little dragon looked at Trixie questioningly. "Is something wrong, Trixie? You’re acting a little weird,” Spike asked as he jotted down the details of the fourth volume of ‘Botanical Studies of Coniferous Plants’. You're not trying to sneak any book from me, are you?”

“What? No, no!” The unicorn continued to hold the book tightly. “I would never do something like that!”

Actually, that was her initial intention once she found the book with the spell she wanted, but her impatience plus the fact that she was supposed to be alone for a while, made her decide to try the spell immediately. Seeing the trouble she was going through, it was clear that it had been a bad idea.

"Alright," Spike replied seriously as he propped himself up with one paw on the table. “Then put the other book on the desk again and show me your hands.”

Oh shit.

Trixie suddenly found herself between a rock and a hard place. Unfortunately, her gestures to try and hide her bulge weren't going to do much good if she didn't have any books to cover it up. And to make matters worse, Spike kept looking at her hands, which were next to her crotch.

"T-There’s no need to be so suspicious, Spike," she insisted. “I'm not taking anything without permission, I assure you.”

"Then why don't you just do as I tell you? I'm not asking for anything weird.”

“Because…!” Trixie was running out of options. The little dragon didn't want to budge on his intentions, and that distrust was really irritating to the unicorn. “Ugh! Okay, fine! There!” she finally decided, setting the book on the table and presenting her palms open in front of Spike's face. “Are you happy now?”

Spike looked questioningly at the book and at the pony's hands. Then he looked her body up and down, perched on the desk, until his eyes suddenly lit up, he got up from his chair and put one foot on the table while pointing an accusing finger at Trixie. Or well, rather to a specific part of Trixie.

“Aha! Gotcha!” Spike declared triumphantly. “I knew you were hiding something! Did you think you could get away with a book under your clothes?”

Spike's reaction seemed so ridiculous and tiresome to Trixie that she sighed and rubbed a hand over her face.

"Wait…that doesn't look like a book." Spike lowered his arm languidly as the gears in his head began to screech, until, realizing what he was really seeing, he winced and blushed deeply. “What the heck is…! Are you a guy with boo-?!”

Before he could finish his question, Trixie quickly covered his mouth with one hand, and this time it was her the one that was pointing a finger at Spike.

“Shut up! Don't say a word about this to anyone or you're gonna get it, shorty,” Trixie threatened through clenched teeth. “This is something between Starlight and me, understood?”

Spike blinked a few times, trying to understand Trixie's words, and finally nodded slowly. The unicorn then removed her hand from the dragon's mouth.

“And no, I'm not a ‘guy’. I'm a mare through and through,” Trixie clarified as she crossed her arms before pointing her gaze at the large bulge in her groin. “Well, except for this. But the point is that this is a temporary spell.”

"G-Geez - I'm sorry. I didn't mean to…” Spike stammered, trying to excuse himself.

"I guess now you understand the act with the books. I didn't want to take out any at first, but I needed something to cover myself up,” Trixie explained. “Now that you know, I'm not interested in taking them with me if you have something else I can use to cover this… bulge.”

"I - erm…I'm sure I can find something." Spike looked around for a few seconds, then finally jumped out of his seat. “I'll be right back.”

The dragon walked out the door and into the hallway.

As soon as she was alone, Trixie let out a sigh that hadn't realized she was holding. It was a relief that she had been able to talk Spike out of asking her any more questions. It would’ve been quite embarrassing to have to answer them in front of a kid like him. Although he’s not that young, right? Starlight told her that Twilight adopted him when he was very young and that he was technically of legal age. Maybe he had a hormonal problem, or maybe dragons just took longer to mature. She didn't know much about them, but she heard that they were very long-lived.

In any case, Trixie needed to get to her carriage as soon as possible and relieve herself. She wasn't sure if it was due to the spell itself or her own arousal, but her new member was constantly claiming her attention. It hadn't softened one bit since she cast it. In fact, the cock was so stiff that it was even starting to be really annoying.

She hoped Spike wouldn't be long.

Luckily, the little dragon didn't take long to bring her something to cover herself with: a folder full of blank pages. It wasn't much bigger than the books, but it was ample enough to cover the bulge just fine. Once with it, Trixie soon said goodbye to Spike and quickly left the castle. She needed to get to her carriage as soon as possible to be alone and soothe her hard erection.

The way back wasn't too long, but seeing each mare she passed by was pure torture. Have they always been this hot? Trixie could’ve sworn they looked the same as always, but she couldn't help but notice every one of their curves. It was the middle of summer, so they were also very lightly dressed. Her mouth salivated with the sway of each breast, the curve of each thigh, the contour of each ass…

Trixie closed her eyes and shook her head. Did Starlight feel the same way every time she conjured her own cock? If she weren't holding back she would have jumped on the first mare she saw and would’ve fucked her right there in front of all of Ponyville. Holy Luna, she needed to get to her caravan now!

Luckily, she managed to get home without any mishap. It was located on the outskirts of town, near the Everfree Forest, to have enough privacy. Trixie was a fairly well-known face in Ponyville due to the fact that she now performed quite frequently there. It was taking her a long time to regain the trust of the townsponies, but that was no wonder considering she had literally enslaved the entire town for a day using the Alicorn Amulet. That was the main reason why she chose such an out of the way spot to park her caravan, and she could be thankful for it considering the predicament she was in at the time.

Once her walking home was in sight, Trixie quickened her pace until she got to her door. She reached into the right pocket of her shorts, but found it empty. She changed the folder to her other hand and reached into her left pocket this time, but what she was looking for wasn't there either.

"Oh fuck," Trixie exclaimed, “I left my keys in Starlight's room!”

The unicorn stomped on the ground in rage. Now she had to go back to the castle to retrieve her keys. How was she going to make two more trips with the martyrdom that had been enduring just one? Her balls ached, and she was sure they were bigger than when she'd channeled the spell, not even an hour ago. Goddesses, she needed to empty them now!

“Watch out!”

As she cursed her bad fortune, Trixie heard a scream behind her, high up in the sky. As she turned, a grayish figure crashed into her from the sky and slammed her to the ground, dragging her for several yards before finally falling backwards onto the grass. The bump was certainly violent and sudden, which left her seeing the stars for a few seconds. With a groan, Trixie cupped her head in one hand to try to ease her dizziness. When she managed to get her vision back, she realized that the grayish figure was sitting on her stomach, scratching its head with a guilty smile as it tried to fix its gaze on her. Emphasis on treating, because the poor thing had problems focusing both eyes on the same place.

"I'm so sorry, miss! A gust of wind knocked me off balance a bit while I was trying to land.” The gray pony, a pegasus mare, flapped her wings slightly to emphasize her words. “Are you okay?”

Although it had grown quite a bit in the last two years, Ponyville was still a small town, so it really didn't take a lot of staff to deliver the mail. Of the two ponies dealing with that, Derpy Hooves was one of them. The gray mare was quite clumsy due to her visual problem and her absent-minded personality, but she did her job with relative efficiency. She was also cheerful soul and very kind to others so most ponies used to forgive her for those little flaws.

Although she hadn't been living there that long, Trixie already knew her. They crossed paths a few times during the pegasus’ rounds and she dealt her some cards personally. However, until that moment she hadn’t realized how hot she was. The gray pegasus was dressed in her summer mailpony outfit, very short skin-tight dark gray shorts, a short-sleeved gray shirt with the top buttons undone, and the typical mailpony cap. The clothes she wore did nothing but highlight her generous feminine attributes: wide hips, slim belly, and large tits that peeked through the wide neckline of her shirt. Trixie was also well endowed in the boobs department, but Derpy managed to be a little more so than she was.

Seeing all that smoking hot body on her was making Trixie salivate and she unconsciously licked her lips before answering: "I-I'm fine. I think... that I have nothing broken at least.” Trixie answered. “Now, could you get up from…?”

“Glad to hear it!” Derpy said, cutting her off. “Well, could you not tell my boss about this, please? I wouldn’t like to have another accident on my resume.” She clasped her hands together to implore Trixie to agree.

The unicorn noticed how Derpy highlighted her breasts even more with that gesture, since she was pressing her arms under them. Trixie swallowed hard as she realized her cock was throbbing under the weight of the pegasus, trapped under her pelvis.

“Alright, I won't say anything,” Trixie answered. “Now I need you to…”

“Oh! I forgot! You are Trixie Lulamoon, right? I dropped myself here because I have mail for you.”

"'Dropped,' of course," Trixie muttered sarcastically.

Derpy reached into the satchel she had slung over her shoulder and rummaged through it. As she groped inside the bag, the pegasus moved her hips playfully, causing her crotch to rub against Trixie's very erect and hard cock. The unicorn bit her lip to try to hold back a guttural moan of pleasure. Her cock had already started oozing precum onto her own belly, causing a wet stain to appear on her shirt.

After a few seconds, Derpy took a sheaf of letters from her bag and went through them one by one, muttering the recipient's names under her breath as she struggled to read them.

“Here it is!” Derpy said suddenly as she brought a letter to within inches of Trixie's face. “Letter for Miss Lulamoon. Or well…” The pegasus laughed lightly as she blushed and moved her hips back to rub the unicorn's cock with her groin. “More like Mister Lulamoon, hehe.”

“Stop!” Trixie turned red and snatched up the letter with a quick gesture. Derpy was a pony who, due to her work, had frequent contact with all of the townsponies, so any gossip or rumor that she found out about was easy for her to spread. And that was very bad news for Trixie. “It's a temporary spell, okay? And if you tell somepony, you're going to get a big complaint from me at your office. Do you understand?”

"Not a word to anyone. Understood, Miss Lulamoon,” Derpy replied as she straightened her back and gave her a martial salute.

Trixie sighed. She just hoped the mailmare didn't slip off her tongue inadvertently. She turned the letter over and read the addressee.

“Derpy… This letter is for some “Pixie Fullmoon”. I am Trixie Lulamoon.” She offered the missive back. “In fact, the address listed there isn't even mine.”

“Oh, seriously? Wow, what a mistake ~ hahaha…” Derpy scratched her chin and smiled awkwardly as she put the letter back in her bag. “I’m sorry for the mishap…”

"Okay... Now, could you get up?" Trixie asked. “You weigh a lot and you're crushing my dick.”

"Oh, sorry! I didn't think I was bothering you that much.” Derpy fluttered her wings slightly and rose from the ground to let Trixie's body free. Then she took her hand and helped the unicorn to her hooves. “There. And now I must go, I have to finish my round.”

Derpy turned around and prepared to take flight, but Trixie held up her hand for a moment to get her attention.

“Wait!” Trixie exclaimed, making the pegasus pause for a moment. “I need you to do me a favor before you go.”

Derpy turned to face Trixie again and smiled. “Sure, Miss Lulamoon.”

Trixie cleared her throat slightly. "Can you stop by the Castle of Friendship and get my caravan keys? Turns out I left them there,” Trixie explained. “Tell Spike they're probably in Starlight's room.”

"Oh? Can't you go yourself? The castle is not that far.”

Trixie moaned in irritation. She didn't want to explain herself, but it looked like she had no choice.

"I could, but this damn boner won't go down and I don't want to sway it around in front of all of Ponyville," Trixie said, blushing.

Derpy looked down and gazed carefully at the bulge in the unicorn’s pants, that went all the way up her shirt. Trixie noticed that, oddly enough, the pegasus managed to keep both eyes fixed on her package despite her visual defect.

"I can see you're having a hard time," Derpy said, jokingly. After that her eyes lit up for an instant and she clasped her hands together. “I have a better idea! What if I help you get rid of it? If I give you a good blowjob I can make it go down.”

“What? Uhhh…”

"I'm sure it will take less time to get back to my tasks that way than if I go to and from the castle!" Derpy blushed for a moment. “Also, I'm a big fan of yours, so I'd really like you to accept.”

“R-really?" Trixie asked, surprised. “Are you a fan despite what I did in this town?”

"Well... it's true that you were very mean to us when that amulet thing happened," Derpy explained, "but you've changed a lot since then! Also, my little girl and I love your magic tricks! That one you did launching yourself with a cannon towards the jaws of that manticore and then appearing in the middle of the stage was incredible and very exciting!”

Trixie felt a slight tingle in her stomach at those words. After what happened with the Alicorn Amulet she thought that she wasn’t going to have real fans in that town again. Before that, it wasn't that she had too many; just that pair of young colts, Snips and Snails; but after how she treated them, it was no wonder they took a dislike to her. It had been a couple of years since then, and though she managed to attract enough viewers to watch her magic shows, ponies generally didn't want to have anything to do with her outside of that. That's why seeing that someone like Derpy had forgiven her touched her heart.

She also had her balls about to explode, so she didn't have a hard time making her decision either.

"O-Okay," the mage replied as she tried to regain her composure. “The Great and Powerful Trixie accepts your proposal.”

“Sweet!” Derpy replied with a wide grin. “I assure you that you won’t regret it!”

Trixie looked around her for any prying eyes. Luckily, even though she couldn't get inside the carriage, the area she had it parked in was a long way from town, so ponies didn't usually hang out there. Making sure no one was there, Trixie motioned for Derpy to follow her and she stood behind the car, towards the side facing the Everfree Forest; that way they were less likely to be caught by someone who suddenly appeared on the road. She began to struggle urgently with the button on her pants, but Derpy quickly went to her and grabbed her wrists.

“No, no, let me do it,” said the mailmare. Then she gave Trixie a mischievous smile. “Opening packages is something I love to do.”

Trixie nodded and relaxed her hands. With that, Derpy dropped to her knees in the grass and got to work. She noticed that the bulge in the mage's pants felt awfully tight, so Derpy went straight to her button and undid it. Then she unzipped her pants, exposing her white panties, which did little to conceal the bulge Trixie had between her legs.

"Perhaps you shouldn't wear such tight clothing when using this spell. You could hurt yourself.” Derpy pulled down the wet panties to set free Trixie's genitals, causing her to breathe a sigh of relief. “Wow, it's a really good size. Especially these,” she said as she rubbed Trixie's balls with one hand, “they look pretty full.”

Trixie suspected that her genitals had grown since she conjured them, and seeing them now seemed to confirm it. She was sure that her cock had grown an inch or so, and it looked a bit thicker. However, the most noticeable change she saw was her testicles, whose size now seemed to reach the size of a couple of apples. No wonder they had been pulling her pants so tightly.

Derpy took her member in one hand and gently rubbed it up and down. Trixie had to bite her lip to hold back a moan at the first touch of those fingers.

"Fuck… It's very sensitive," the mage muttered.

The pegasus brought her snout close to the dick and sniffed deeply. Then she licked a thread of pre that sprouted from the tip and made a face of satisfaction.

“It has a strong scent, but also very sweet. I need to taste it again!”

Saying that, Derpy inserted the tip of the swollen phallus into her mouth and began to suck on it greedily, trying to lick up every drop that flowed from its urethra. The wet, warm mouth of the pegasus felt glorious, like it was the place Trixie's cock was made for. After licking it hard, Derpy pulled the rod out of her mouth and took a deep breath.

“It's delicious! I’ve never tasted such a yummy cock,” Derpy commented with fascination. Then she took the member with one hand while she watched it thoughtfully. “It's a little big, but I think I'll manage just fine.”

She then opened her mouth and inserted half of the cock into her throat. With a little more effort, Derpy pushed her head in little by little until she managed to swallow the member completely.

Trixie had never felt anything like it. The pegasus's throat engulfed every square inch of her cock, and her tongue slithered to caress every fold and crevice, trying to give her as much pleasure as possible. And boy was it working. The unicorn's knees were shaking like jelly, and a sudden tingle ran up her back. However, Derpy had only just begun.

After keeping Trixie's hard member whole in her mouth for a few seconds, Derpy began to move her head steadily. Her wet mouth and throat rubbed against the eager cock as she moaned softly. It wasn't the first time that the pegasus had given someone a blowjob, and it wasn't even the biggest she had ever tried, but the fact that that succulent cock was protruding from a mare gave it a novel and very exciting edge. And that's not mentioning that that mare was the Great and Powerful Trixie!

The magician's brain, on the other hand, melted with pleasure at Derpy's deft movements. The pegasus was a few years older than Trixie and, from what she noticed, she knew very well what she was doing. With each swing she felt closer and closer to orgasm. She had never felt one with male genitalia, but it seemed to her that she was reaching the point of no return. Instinctively, she took Derpy's head in her hands and began to move her pelvis, pushing her cock all the way down her throat. She was a little surprised at Trixie's impetuousness, but she let her do.

“Oh shit! I'm… I'm going to…!”

Derpy listened to those warning words and pressed her face hungrily against Trixie's crotch as she squeezed the magician’s buttocks with her hands. She was in her work uniform in the middle of her workday, so she was going to try and swallow all the cum Trixie would expel so she won’t get dirty. She suddenly felt the cock in her throat throb hard, expanding a few millimeters with each pulse. Just when Derpy was starting to get trouble to keep that growing cock inside her mouth, she forcefully expelled the first stream of cum. The pegasus managed to swallow it with some difficulty, but then came another one, and then another, and another, and another... Despite her efforts, Derpy had to give up after six copious jets of sperm and extracted the swollen cock from her throat by pushing Trixie's thighs. As expected, the unicorn's cock was still in full eruption, so a copious amount of cum drenched Derpy's face, causing her to close her eyes instinctively. More and more blasts of the virile, gooey liquid were expelled from the rod in chaotic patterns, covering the body of the exuberant pegasus.

Suddenly, Trixie watched as her new genitalia got surrounded by a kind of black light. Her spurts of sperm dwindled in strength and volume to a trickle, and just as they had appeared, the mage's stud parts disappeared in a blackish flash. Exhausted by this burst of new sensations, Trixie sank to the ground with her back against the wall of her carriage and closed her eyes. The last thing she saw before she blacked out was Derpy's kneeling figure, wheezing and completely drenched in her sticky white cum.

Caramba! Who would have thought that those balls would be so productive? Derpy had never seen such a copious cumshot in her life. What an amazing spell!

After catching her breath, she approached the unicorn to check her condition.

"Miss Lulamoon, are you all right?”Derpy asked cautiously as she lightly shook her shoulder.

Trixie took a few seconds to answer, but she nodded slightly with a light smile while keeping her eyes closed. Or so Derpy thought. The gesture was so weak that she wasn't sure if Trixie had really heard her question. Still, The unicorn seemed more relaxed than anything.

It was almost noon and Derpy had to keep delivering the mail, but she couldn't leave Trixie lying outside either. The best solution would have been to leave her inside her own caravan, but since she didn’t have the key and going to the castle meant leaving her alone in the open, she finally decided that the next best thing would be taking her to Derpy’s home. Once there she would leave her a note and continue with her deliveries. Of course, before all that she would have to clean the…

Derpy was puzzled for a moment. She looked at her arms, her breasts, and touched her face. Her body was completely dry. She was, without a doubt, drenched in cum just a few seconds ago, and yet, she didn't have a drop on her now. In fact, she noticed that there weren't even traces of it on the ground. Maybe the liquid evaporated along with Trixie's package? What a convenient spell!

Wasting no more time, Derpy lifted Trixie up a bit so she could put her panties and pants back on. It wasn’t convenient to carry her while she was ass naked. Once that was done, she took Trixie's unconscious body by grabbing her under her knees and back and took flight. Flying while carrying an adult pony required quite a bit of effort, but luckily her house was close by.

Of course, as soon as she could, Derpy was going to check what the heck was happening in her crotch, because she felt a strange tingle down there...
