Skies had just finished a particularly long day of writing work. It was pretty tiring with how much he got done that day, so he decided it best to unwind with some casual online viewing. He opened up a streaming website, deciding he wanted to wind down by watching some video game streams. Skies opted not to go with anyone he was already familiar with, instead deciding that he wanted to try something new. 

While browsing, he came across a curious channel called "EeveeTeevee," and upon clicking into it, saw that it was a team of streamer girls, all of various Eevees. On the stream, there was a Sylveon girl playing some shooter game as a part of a sponsored segment. Despite not being too interested in the game, Skies still wanted to see if he'd enjoy watching the channel and stuck around. 

"Looks like we have a new viewer in the chat! Hi Skies!" she smiled, giving a "heart" sign with her hands. "Welcome! I'm Sylvily!" 

Skies was pretty taken aback by being called out directly, especially considering the stream had a good bit of viewers and chatters. He was a bit more of a lurker, and decided not to say anything. 

"What's the matter? Cat got your tongue?" Sylvily asked with a giggle. "You better change that, you're on after me!" 

"I'm...on..?" Skies was only more confused. He was going to click off the stream as it was starting to get a bit too weird for his liking, but felt himself compelled to stay on the page, ultimately unable to close it. 

"Of course you are, silly! Don't be such an airhead!" the Sylveon responded with a giggle and a wave of her hand. "That's why we're a team! We all only stream for a few hours, so every Eevee gets a chance to shine!" 

"Every...Eevee...?" Skies found himself confused, almost in a trance. 

"Yeah! And it's gonna be your debut! Don't worry, I was SUPER nervous when I first started, too! The chat can attest!" Sylvily smiled. "But it's all gonna be okay! Once you sit in front of the webcam and start talking to chat, all those worries just melt away!" 

That did sound nice, Skies had to admit, he was nervous about talking in front of hundreds of people at once, all having come to the stream to watch him. He shook his head. That wasn't right! He wasn't a streamer, he just wanted to watch a stream! But...the idea didn't sound too bad. It could be fun...

"I'm almost done, once I finish this boss fight, the sponsored segment will be over! The most veteran EeveeTeevee members handle those! Maybe if you stick around with us long enough, you'll be doing them too!" 

Skies couldn't help but form a smile on his face. It wasn't right, and yet, it sounded perfect. Everything about what Sylvily was saying sounded exciting! And he couldn't wait to join the EeveeTeevee team! He was shocked when he got in, but...he wasn't an Eevee or a girl! Or...was he? That's right! He had to finish changing first! Skies' mental confusion and battle were draining him, in more ways than one! As he was distracted by the conflicting feelings, his physical body started to change, not waiting for the mental changes to finish. 

Skies' skin would change color, turning primarily a light ocean blue color, becoming soft with the slightest bit of moisture forming onto it. His hair would turn a darker shade of blue, becoming thicker and firmer as it became another layer of skin as opposed to hair. The changing man's ears receded into the sides of his head, becoming but simple holes that were invisible to the naked eye but Skies’ was still perfectly capable of hearing. Where the ears were, a new appendage grew out in the way of sizable fins, the top the same dark blue on his head with beige membranes ruffed underneath them. An extra fin of the same size and pattern formed at the top of his head, only that was sticking upward rather than outward. Skies' face stretched outward, forming into a modest muzzle as his nose shrank and turned black and triangular at the tip of it. The teeth inside of his maw became slightly sharper and a bit more animalistic. Around Skies' neck, a frilly white fin wrapped around the entirety of it that was just wide enough that it expanded past his neck and shoulders. 

Skies' facial features softened, with his eyelashes becoming longer and more noticeable, especially near the upper corners of them. His eyebrows became thinner, giving his face a more feminine appearance. To match, the lump in his throat shrank in size, causing his voice to rise up drastically in pitch. 

More of Skies' skin transitioned into the aquatic blue color that was found on his head. All of Skies' body had transitioned into the light blue color, with one minor exception. Going down the back of Skies' neck and down his back would be thin, dark blue spines matching the darker shade of skin at the top of his head. From behind Skies' an entirely new appendage grew out that was almost as long as his body itself. It had a thick, circular base that eventually got thin near the tip, where two water-drop-like shapes emerged to give the tip of Skies' tail some more fins. On the upper half of the tail, the spines on Skies' back continued, not stopping until they reached the tips themselves. The digits of Skies' feet merged together, leaving only three with each remaining digit larger, the nails turning into dulled black claws as the structure of Skies' legs altered, forcing the paws up to the front as the structure of them became digitigrade. 

Skies' shoulders slimmed down, their build becoming much more narrow while his arms became thinner, taking on a more slender appearance. To match the new proportions, Skies' hands shrank in size, now much more dainty than before, with a smaller overall size, along with thinner and longer fingers. The opposite was happening to Skies' legs, which instead became a bit thicker, with thighs and calves enlarging to give Skies' legs a more shapely tone. 

At the sides of his body, Skies' figure sucked inward where it remained, giving him a permanent indent near the navel. Similarly, his back would push in to give it more of an arch. Below the belt, Skies' hips expanded outward, growing into wide, childbearing proportions. His rear built up some extra cushion, enlarging to a more pert and pronounced size. All of this left Skies with a curvy, hourglass figure. 

Skies' chest grew outward as two mounds built up, growing as both weight and sensitivity formed there. This left Skies' with a rather ample pair of breasts resting there. Between his legs, Skies' manhood receded back into his body, leaving only a flat opening downstairs while his reproductive workings swapped to those of the opposite sex. With that, Skies' was a human man no more, but a Vaporeon woman. 

The clothes that Skies was wearing changed a fair bit. The sleeves of his T-shirt shrank upward, not stopping until they became thin straps hanging loosely on his shoulders. Meanwhile, the collar of the shirt dipped down dramatically as it widened, not stopping until it reached halfway down his chest, revealing a hefty amount of cleavage. The lower cut of the shirt shrank up as well, exposing a bit of his midriff while the material became softer. The color turned a purple with white lining around the outline of the interior of the new tank top. Skies' jeans tightened around his legs, the material becoming softer and turning black with white lining. Afterward, the pants rode up his legs, not stopping until they barely reached his hips as they became curve-hugging shorts. Lastly, a pair of black leggings formed that reached up to his thighs, completing his new outfit and stream attire. 

With all of the physical changes done, the last of the transformation concluded in Skies' mind. Try as he might to focus in on his "proper" mind, with a body that looked nothing like what he was telling himself, he was doubtful what he was thinking was true. This allowed the new personality to overwrite Skies as he became an entirely new person with no recollection of his old life. 

Now, Skies was Lorelei, although, she was better known as her screen name "Vap Vap," a nickname she earned herself due to her frequency of ending sentences with it. The catchphrase would make for great merchandise, something EeveeTeevee would sell, assuming she had a good debut stream, which they were confident she would. 

"Alright chat, my time is done!" Sylvily said, taking off her headset and smiling. "But, don't go anywhere! We have a new Eevee running the stream! If you like her, make sure to show her some love so she can become a full-time streamer with us!" 

The stream went on pause as Lorelei saw that Sylvily was calling her. Excitedly, she accepted it. 

"Hello! I'm so ready! Thank you for the chance Sylvily!" Lorelei answered, finding it hard to contain her giddy she was.

"Please, call me Annie! I'm just Sylvily on camera!" the Sylveon couldn't help but giggle. "You'll have free rein to do WHATEVER you want for the next two hours! Feel free to have fun with it!" 

"Oooh, I can already think of a ton of fun ideas! I can't wait to meet the chat, I hope they'll like me!" 

"I think you'll do just fine! I've been here since day one, I know a future EeveeTeevee star when I see one!" Annie reassured the Vaporeon. "I sent all the information you need to sign into the stream. Good luck, Lorelei! Show the world that Vap Vap is here to stay on EeveeTeevee~!" 

Annie hung up, Lorelei inputting everything into her streaming program so that she could sign into the official EeveeTeevee stream. She took a deep breath. This was it, her big debut! She had dreamed about this day ever since she discovered EeveeTeevee by chance, and now she had the chance to be a member of it with all the other awesome Eevee streamers! 

She clicked the "go live" button, changing from the "be right back" screen as her webcam setup came into view of the streamers at home. "Hi, hi, everyone! I'm Vap Vap, and I'm gonna be taking over the stream!" she waved with a big grin across her muzzle. "Hope you all enjoy the stream, because I sure know I am! We're gonna have so much fun together!" 

She went about the stream, chatting happily with the curious chatters, answering any question that was asked as she played through a "low-key" game that made it easy to keep talking to chat. She made sure to give love to everyone, responding to donations with excitement and never having a smile leave her face. This was awesome! 

After a successful few hours, Vap Vap's streaming slot was over. "Alright, I gotta go now, Umbaeon is coming up next!" Lorelei informed the stream. "This was like...SO much fun! Thank you for making this such a fun debut! I don't think I've EVER had this much fun before! And thank you so much for EeveeTeevee for featuring me. Make sure to tell them how much you loved me if you want me back!" she giggled, seeing the chat begging for Vap Vap not to go. It looked like they liked her! 

"I'm signing off, stay fun, Vap Vap!" she made a heart with her hands as her screen cut to the "be right back" screen to transition to the next streamer. 

Afterward, she noticed Annie calling her back, Lorelei wasting no time in answering it. 

"So? How did I do?" 

"I thought it would be obvious with how the chat was engaged, you did great, Vap Vap!" Annie couldn't help but giggle. "I think it's time you come over to the EeveeTeevee headquarters and stream with us for real! 

"Woohoo! I can't wait! I'll start packing now! You are NOT gonna regret this! This is gonna be so much fun!" Lorelei cheered, beyond excited to be joining EeveeTeevee as a permanent member and its signature Vaporeon streamer!
