Ashera had left the kingdom of elves what seemed like ages ago on her journey. The even queen had told her of the importance of this mission. There had never been a successful emissary to the centaurs and she would be the first in 100 years to attempt again. It was an incredible honor to be chosen for a mission of such importance and Ashera was going to succeed to matter what it took. On the final day of her long trek, Ashera dawned her best clothing that she'd brought with her just for this occasion and started down the flower lined forest path that lead to, what she assumed was the kingdom of Centaurs. So little of was known of their race by the elves that she had no idea what to expect. Would there be giant gates or an army of their fiercest warriors? She had no idea, but would soon find out. The path straightened out and the flowers became even more colorful than before. Far down at the end of the path was a single gondola with someone resting under it's eaves. Focusing with her sharp eyes Ashera saw a centauress for the first time in her life. Stealing her nerves she approached the magnificent looking creature. A soft hum filled the forest around the centauress as she appeared to sing to the plants around her. As Ashera approached, the centauress took note of her presence. Ashera stopped and bowed lightly to show she meant no harm and the centauress smiled, opening her arms in welcome.

Ashera approached the centauress, her armor glistening in the sunlight that shone through the trees and a large welcoming smile on her face. The sound of birds singing without care to their presence and the wind, gliding through the forest met with her elf ears and she suddenly felt relaxed. Once close enough, the centauress spoke up, "Greetings traveler, you must have come from afar, what is your purpose in these woods?" Her voice was gentle but carried a warning in it's undertone that reminded Ashera was still an outsider. Ashera observed the centauress' ornate armor and thought she had to be royalty of some kind, so she must tread carefully. "I have come to be the first emissary to the centaurs," replied Ashera, "Would you happen to be their queen?"
The centauress raised a brow in surprise, "Many have come before you but none have passed our tests. What makes you think you will do better?" the centauress responded, ignoring the second question. Ashera figured she'd guessed right by the lack of response to her question of royalty and pushed forward. "I will not fail the tests my Queen, that I can guarantee," she responded, her voice steady and confident. The centauress laughed softly while reaching to grab a flower and stood to approach Ashera. Ashera knelt as the centauress approached, flower in hand. As she came closer, the flower started to glow brightly in her hand and spores of glowing pollen gently floated away from it. "Very well," the centauress said, "We shall test you, both of mind and body."
The centauress gently grabbed Ashera's hand before offering the flower. Not knowing exactly what to do, Ashera leaned forward to smell the flower and took a deep breath. The glowing pollen and it's wonderful sent flowed into her nose. Instantly her body warmed and her senses spiked. Her nipples started to puff up and became super sensitive while between her legs burned with a passion for pleasure like she'd never experienced. Her nipples rubbed against the soft fabric of her dress causing little spikes of pleasure to flow through her. Ashera's face reddened with embarrassment. The centauress noticed this and lightly laughed again and said, "You may removing what linens bother you, we do not judge based on clothing." Unsure but thankful, Ashera decided to unclip the cloth cover her breasts, and light orgasm caused her already wet pussy to quiver as she did. As the cloth fell away, the sensitivity only increased as did her rate of breathing. Ashera looked up, and the Centauress watch her smiling and softly said, "The first test has begun."

.:3:.
Knowing she'd probably have to be vigilant for these tests, Ashera attempted to maintain her composure as her body became increasingly turned on. "What in all the kingdoms is happening?" she thought to herself as her breathing was getting louder and her pussy was now dripping it was so wet. Her clothing started to feel restrictive and needed to come off as well. Since the centauress said it wasn't needed she felt little shame now in removing it. As she slid the dress down to her knees and rolled to her side, she happened to glimpse a surprise the centauress was revealing. A throbbing shaft slowly grew larger and larger and had started dripping with pre cum.

Ashera looked away, embarrassed as if feeling as though she'd caught a glimpse by accident but couldn't help but look back again. Her entire body burned with desire and there would be no way she could deny it. She briefly touched her pussy, her lips so puffy and sensitive, she could think of nothing else but the shaft before her. Looking up the centauress returned her stare, biting her lip waiting for Ashera to ask permission. Ashera felt a wave of pleasure wash through her as she watched the centauress remove her chest armor, and her massive breasts hung down as she leaned over to set the armor on the ground. Taking this as her invitation, Ashera slipped under the centauress, hanging from her armor and positioned herself near the shaft with surprising agility and strength. Directing the shaft with her free hand to her vagina Ashera pushed it inside her. Fluids instantly flooded inside her. Cumming already? No, there was no ejaculation, only precum flowing from that massive horse shaft instantly filled her vagina with lube. It sent a pleasurable quivering orgasm through her in response as she started rocking back and forth on the shaft. Each time the shaft slid farther and farther in and it continued to grow in size, slowly becoming harder.

After a impressive amount of time, the centauress had finally had enough of Ashera running the show and moved to her flowered archway and allowed Ashera to lie down on the stairs. As soon as Ashera's rear hit the steps, the centauress knew it was her turn to drive. Her shaft slipped back in to Ashera and drove deeper than the elf could have ever imagined.

The orgasms that rocked Ashera were like nothing she'd ever experienced as the centauress' shaft continued to expand and harden. "How much bigger could it get?" Ashera thought before the shaft plunged deep into her vagina again causing more and more pleasure to flood through her body each time. Ashera could feel other changes with her body that started around her hips and seemed as though it was spreading over her. Each orgasm caused these changes to progress. Stretching of some parts, expanding of others and every time it occurred, it felt better and better. She could think of nothing else she wanted more than the orgasm and subsequent expansion and change of her body.
Gripping the stairs, Ashera let the centauress work her magic with her still expanding shaft while Ashera's breasts bounced and expanded more with every thrust of the shaft inside her.

.:5:.
The massive horse cock continued to ram into Ashera's pussy with such impressive force that she started sliding across the ground. The harder it rammed inside her the better it felt for both parties involved so Ashera decided she needed to find a stronger position to hold her ground. The centauress stopped for a quick switch in position by Ashera before the shaft once again plunged deep into her pussy.

How was she able to continually take more and more of the shaft? She could feel her body changing on the outside, was it changing inside as well? It didn't really matter to Ashera, the only thing she wanted was to take more of it's length. Each time it plunged in, the resulting pleasure was stronger than the last and the orgasmic feeling of her body stretching and growing only added to this. Gripping the centauress' front legs allowed her to brace her body against the strength of the massive shaft plunging deeper inside her. She could feel the massive shaft starting to twitch and quiver the more it pounded her pussy and the pitch of the centauress' moans getting higher and higher. Finally the giant shaft started switched from a quiver to a ejaculative pump as loads of cum flowed into Ashera. The feeling of the hot cum flooding inside her drove her over the edge and her whole body quivered and shook in orgasmic delight as load after load of hot cum gushed inside.

.:6:.
Orgasms ravaged Ashera in what seemed like an unending torrent of delight as her body continued to shift and shape itself. Finally the orgasms had weakened the legs of both parties involved that a new position was in order as neither was interested in stopping.

Lying down, Ashera positioned herself comfortably on the side of the centauress and placed the shaft near her pussy lips. Cum was still dripping out of the shaft as it was slid back in, filling her up once more. Ashera was instantly rewarded with another wave of pleasure her transformation continued on. Her face tingled and stretched into a more elongated snout and the changing shape of her head and ears finally caused her hair to fall free from it's ties and even took on a more wild and wavy appearance. Her breasts hung heavily from her chest, bouncing and shaking each time the shaft plunged inside her. Her hips had grown much wider as well which greatly helped accommodate the girth of the centauress' shaft. Even her feat had nearly fused into a single hoof, just like those of the centauress she was with. Every shift and change of her body continued to send waves of pleasure through her. She didn't know what kind of magic this was, but all Ashera wanted was more of it. The two continued pleasing each other as load after load of hot cum flowed into Ashera's quivering pussy which seemed to drive her transformation forward.

.:7:.
Eventually the hot streams of cum pumped from the massive horse cock ran dry and Ashera repositioned herself against the centauress twitching and quivering from the residual orgasms. Her body continued to stretch and shift, but much more slowly now. Ashera's heavy breasts bounced against her chest as she tried to calm her breathing and even the slightest brush against their sensitive skin sent little tremors of pleasure throughout her body.

Having thoroughly enjoyed the experience, the centauress reached down caressing Ashera's shoulders before speaking. "It has been generations since I've come across an elf that could please as well as you," said the centauress in a seductive voice, " but it looks as though your transformation has slowed, give me one second and I'll grab another flowe......"
The centauress slowly began to stand while speaking but Ashera cut her off, "No my queen, please, allow me!" Ashera said before turning to grasp the long shaft of the centauress once more and slowly began stroking it.

On the way
The centauress quickly stood up, flower in hand and spell in progress, surprised by Ashera's quick movement. Her shaft had already slid down the now long mouth and throat of the elf, her large tongue stroking the urethra of the centauress' shaft. The rhythmic sucking sent coursing waves of pleasure through the centauress and Ashera was instantly turned on again, her pussy dripping wet with anticipation.

"You... You don't ha..have to....," the centauress tried to get out but it was too late. Her long horse cock started to twitch and pulse and hot cum started to flow from it's tip into Ashera. Ashera sucked hard on the shaft in the belief that the cum was the true driver of her transformation as the enchanted pollen slowly floated over to her body and absorbed into her. The last of her skin slowly began to change as the transformation made its way down her arms and her muzzle. The more of the transformative flower pollen her body absorbed, the better it felt. Before long both Ashera and the centauress were once again, enjoying another wave of orgasms as Ashera emptied out what little cum remained in the already spent centauress.
