"Alrighty Spike, we're going to try out a new spell this time."
Twilight was standing in the library's living room with Spike. Well, standing is more of a relative term. Lightly bouncing seems to fit better. She had found a new spell book while helping Rarity with some gem finding the other day, and had been excited ever since.
"What spell are we going to do this time, Twi? One that makes any mare I smile at fall madly in love with me? Or maybe a super muscle builder so I can amaze Rarity with my awesome biceps and pecs?"
"Oh settle down Spike," Twilight giggled. "This spell is supposed to transform us into the opposite gender. I bet it would make a great subject to report to the Princess about."
"Wait, so you'd turn into a colt, and I'd turn into a mare? Twilight, why would I want to lose my manly attributes and turn into a girl?" Spike questioned. "That's daft."
"It's just for research purposes, Spike. I bet the Princess would be intrigued with my findings. Besides, I think it could be fun," Twilight said.
Spike was a little hesitant at the idea of giving up his manly status as Ponyville's only male dragon, and a handsome one at that. Crackle came to visit every now and then, but Spike was never sure if Crackle was a guy or not. He decided to let Twilight have her fun.
"Fine, let's just get this over with."
"Thanks Spike. You're always such a wonderful assistant", Twilight said in a sultry voice while batting her eyes at him.
"Ugh, how do mares always get us guys to do whatever they want?" Spike mumbled while Twilight giggled at his response.
"Ok Spike, are you ready?"
"As I'll ever be."
Twilight began to mutter the gender swapping spell that she had read from the new spell book. Two circles of light filled with various symbols formed around her and Spike as she continued to recite the spell. The circles glowed brighter and brighter with Twilight's chanting until she spoke the last words of the spell. "Mickey Rooney Switcherooney!" There was a flash of light that blinded Twilight and Spike, but when the lights faded, they could see each other clearly. Or what they had become.
"Twilight, you look...handsome."
Twilight's mare-like body had been replaced with a slightly muscular colt's frame. His muzzle was a little longer with a more set jaw line, and his mane was short and kind of scruffy, same with his tail.
"Thanks...Spike."
Twilight was taken with his new masculine voice, but was more amazed with his assistant's new appearance. Spike had grown taller, something that he didn't expect to happen. She had feminine curves, and her face still looked the same, albeit with a sleeker profile. She also had two large mammary glands on her chest. He knew that some mammals had them, but had never heard of female dragons having them.
It was at this point that Spike realized that she was looking down at Twilight. "Whoa, did I get taller? And my voice sounds so, ladylike."
Spike looked down further and was met with the two round objects that were attached to her chest. "What are these things?" Spike asked while lifting them in her hands.
"I believe that those are called "breasts", Spike." Twilight was still getting used to his deeper voice and his assistant's new body, while Spike was getting used to her breasts.
"Hmm, well they're pretty soft, so I guess they're alright."
As Twilight continued staring at Spike, he felt a stirring in his loins. His new, meaty loins.
What's happening to me? I was always into colts, but seeing Spike as a girl is making feel, aroused? Maybe this will be a good finding to report to Princess Celestia after all, as soon as I can focus again.
Spike had finished fondling herself and decided to take a look in the mirror to see herself for the first time since the transformation.
"Hey Twilight you should check yourself out in the mirror. I actually look good! He-llo beautiful!"
Spike saw that she had green nipples that were peeking out between the soft scales that covered her breasts. She got quite the surprise when she looked down, though. Her penis was missing. Well, it wasn't missing, but she didn't have one anymore. Spike saw that alongside the breasts and added height, she had been issued a vagina. Free of charge even! She reached down and spread her labial scales apart to see what exactly she was working with.
"So this is what it's all about."
Spike's color scheme seemed to stay true to every aspect of her body, as her clitoris and the lining of her vaginal walls were also colored green. She pushed a finger inside and felt her spine stiffen and shivers ran through it.
"Wow, that felt great. Mares are so lucky that they have this all the time. Hey Twilight, look! Twilight?"
Spike turned around and saw that Twilight was messing around with, well, more or less "analyzing" the Raging Semi that he had acquired. She then got a strange feeling in her loins as well. Her moistening, soft, velvety loins. It looked different than her dick used to. Instead of a pink rod that tapered off at the end, Twilight's cock was a slightly darker purple than the rest of him, and the same size up until the slight flare at the end. She also took notice of his balls, which were each about the size of a plum.
Spike shifted her legs closer together, as if trying to contain the feelings she was having. She had always loved Twilight as a friend, but had never really thought of him in a romantic way. It could have been a side effect of the spell, but she was getting horny thinking about him. Thoughts ran through her head. Sticky, sweaty thoughts. Thoughts that sounded like breathy moans and flesh slapping together. Thoughts that felt like a colt's tongue dancing against her own.
She got an idea. If Twilight was so adamant about studying the effects of the spell, she could convince Twilight that sex while under the effects of the spell could make for a good topic.
"Hey Twilight, follow me upstairs," Spike said as she walked up the stairs towards the bedroom. Twilight just stared at Spike's swaying rump for a few more seconds before complying. When he made it to the room, he saw that spike was sitting on his bed with a devious smile on her face.
"Listen, you want to study your findings on this spell right? I remember how you wanted to study me at some point, so we could get both of these out of the way right here and now. We could fuck, and then you could write all about what you've learned from it to the Princess afterwards. Wouldn't that work out?"
"You're right!" Twilight beamed. "If I send Princess Celestia my findings on both of these studies, just imagine how impressed she'd be. Alright Spike, let's do it!"
Twilight magicked a quill and an empty book over that was titled "Ways of the Dragon."
"Uh, Twi? Aren't you going to write everything after we have sex?" Spike asked.
"I don't want to forget anything during, so I'll screw and scribe at the same time."
"Huh. O.....kay? Well, just sit up on the bed here so I can get started,"
Spike moved off of the bed so Twilight could take her spot. As soon as he was seated, she crawled back onto the bed until she was kneeling over Twilight's face.
"I heard that mares liked getting eaten out, so how about you do me?"
Twilight knew that to be true from her romance novels, although he had never experienced it himself. He decided that this would be fun, and obliged.
"Alright Spike, let's get to work," Twilight said before he began tasting Spike's pussy. She moaned with pleasure as Twilight's tongue lapped at her lady parts. She closed her eyes and let her lips part slightly as her hips started to slowly rock back and forth. Twilight was making sure he was doing a good job with his tongue, being attentive to her insides, labial scales, and clitoris, as well writing down his discoveries in the book.
The inside of Spike's vagina is coated with a smooth mucous membrane. It has a slightly sweet flavor, akin to a lime. My oral ministrations upon the vulval scales and vaginal walls causes the walls to clench every so often, as if trying to acquire more physical contact from my tongue, providing a fair amount of pleasure to Spike.
Spike noticed that Twilight was writing in his book and thought that he was probably getting bored, so she decided to switch the roles up. She retreated off of the bed and knelt down in front of Twilight, motioning him to sit up. She then proceeded to feel the soft and wrinkly texture of Twilight's balls. She let her tongue escape her and moved around one of his testicles, savoring the musky and salty flavor. She then sucked it into her mouth, swishing it around with her tongue. She could hear Twilight exhale and thought that she was distracting him from his studies. She wanted him to focus on her for the time being, so she opened her mouth a little more and sucked his other ball inside her mouth, her tongue moving across both.
Spike looked up, expecting to see Twilight with a serene look of pleasure on his face, but instead saw a look of intense concentration and thoughtfulness on his face, while still writing in his book.
Really?
Spike decided to stop playing around. If she was going to rock Twilight's world, she'd have to step it up a notch. She pushed Twilight's balls out of her mouth and began handling his partially flaccid length. Spike worked her hands up and down Twilight's shaft until it became firm, enjoying the feeling of his cock in her hands. She then popped the tip of Twilight's colthood into her mouth, which earned her a gasp from Twilight. She was on the right track.
Spike coiled as much of her tongue around Twilight's Cock as she could and began working it in and out of her mouth, enjoying Its length and firmness. She thought she tasted grape. Maybe Twilight was a zebra in a past life. Spike took to fondling his balls as well, while continuing the blow job. She thought she was making good headway with making Twilight cum until she felt a tap on her head and Twilight's voice.
"Hey Spike, can you hold off on what you're doing for a minute? I need you to send this letter to the Princess," Twilight said, holding a scroll down to Spike.
Seriously?
"Oh fine." Spike removed Twilight's dick from her mouth, uncoiled her tongue from it, and released a puff of emerald green fire that spirited the scroll away to Its destination. "Lay back on the bed Twi," Spike said as she sighed and pushed Twilight back onto the bed. Spike then straddled his waist and positioned herself above Twilight.
"You ready for the main course, big boy?" Spike breathed.
"Sure am Spike, more findings for my book", Twilight said, without an ounce of anticipation for the sex, but sounding like he was really just looking forward to collecting more data. Spike picked up on this and sighed in her head.
For all of his smarts, he sure is a dunce when it comes to having fun. Gonna have to change that
Spike licked her lips as she lowered herself down onto Twilight. She gasped when Twilight's cock entered her.
"Oh yes."
She began rocking her hips back and forth against Twilight's as she reveled in the pleasure. She closed her eyes and leaned her head back as her breathing became shallow. After a few minutes of this, she opened her eyes and noticed that the book and quill weren't floating in front of her.
Looks like I finally got through to him. He can study afterwards. He's mine for now.
Spike looked down and to her dismay, Twilight was working on a rubix cube. Spike stopped riding Twilight and opened her mouth as if to say something, but was so nonplussed that she couldn't speak.
You gotta be KIDDING me!
Spike finally managed to get her bearings back and climbed off of Twilight. She'd have to get Twilight more involved if she was going to show him a good time.
"Off the bed Twi."
"Hmm? Oh okay," Twilight said as he put his rubix cube on the bed stand. "I was just taking a quick break from writing everything down. Cramming all at once isn't good."
I'll get you to give me a good cramming.
Spike positioned herself at the edge of the bed and bent over, wagging her butt at Twilight. "It's your turn. Show me what ya got, baby."
"Sure thing Spike," Twilight said as he saddled up behind Spike and positioned his member at Spike's entrance. He magicked his book and quill towards him and thrusted into Spike.
"Paradiso," Spike breathlessly gasped. Twilight quickly began picking up the pace in both his thrusts and his writing. Spike's mouth fell open and her tongue lolled out.
Fluttershy was right. Getting fucked senseless by a colt is amazing!
Spike's thoughts quickly began to fade as she neared orgasm. She started panting faster as the big bang approached. She gripped the bed sheets and clenched her teeth as she rode out her first orgasm. She let her head drop onto the bed for a few seconds before looking back at Twilight, who was still pounding away, and still writing in his book.
Upon reaching orgasm, Spike's vaginal walls repeatedly clench themselves around my penis, as if to milk semen from it. Her body shivers throughout the duration, likely from a pleasurable sensory overload.
Spike had had enough.
"Come on Twi, you're supposed to be enjoying this as much as me! You can write down the rest of your studies or whatever later, but you need to loosen up now!" Spike whined.
Twilight was about to protest, but the pout that Spike had on her face was irresistible.
How do mares always get us guys to do whatever they want?
"Okay spike, I'll finish up on my findings after we're finished. For right now, it's just me and you."
Spike was ecstatic. "Yay Twilight, Thataboy! Now how about you give this little slut a nice dicking?"
"Sounds like a plan to me," Twilight said was he laid Spike on the bed and positioned himself. He pushed himself inside Spike with a grunt. Spike moaned as Twilight began to hammer her with everything he had. She wrapped her legs around Twilight's waist to pull him closer as he collided against her. Twilight was amazed at how good sex felt, and wondered why he didn't focus on Spike earlier. He gritted his teeth as his orgasm drew near, and could feel that Spike was getting close as well.
Spike couldn't even think straight with the way that Twilight was carrying on. She then felt her entire body seize up and trembled as her climax hit her. She let out a loud, wavering moan as the waves of pleasure took her under. Spike's orgasm was enough to push Twilight into his own, and he yelled out as he slammed into Spike a few more times before he released himself inside of her and filled her with his seed.
Spike could only see a flush of colors before her eyes for the first few seconds as she was coming down from her peak, as if Rainbow Dash were frantically jumping up and down in front of her, babbling about that candy vag she was always going on about. Spike's first thought made it clear about how she felt about the days happenings.
I'm never going back to before.
She leaned up on the bed, Twilight's cum still pooling between her legs. She could see that he was at the bed stand finishing up his book.
"You were right Spike, that was awesome! After I finish with this, I need to get down to Rarity's and pick up a doll to take to Big Macintosh. speaking of, I haven't seen Smarty Pants since my little breakdown. I'm sure she'll turn up around here.
"Big Macintosh? Don't worry about that Twi, I'll take care of it," Spike said as she licked her lips.
