To say that Erin Harrison is plain is an understatement. Despite being 19 years old, it seems to her that the puberty fairy has passed her on giving out her blessings. Standing at an awkward height of 5'8" and weighing a grand total of 150 lbs soaking wet, Erin would be surprised if anyone had paid attention to her. Especially in comparison to her younger sister, Effie, who seems to outshine her in everything. Including sizes. Even though Effie is younger by 3 years than her older sister and stands at 5'5", her asset is 3 times that of Erin's near-flat figure. Effie even beat her sister in the amount of friends and boyfriends in comparison to Erin's lack of friends. If strangers had seen the two sisters together, they would've thought that they were friends rather than sisters.
So it was a surprise to Erin that her phone got a brand new app that just has the name "CYC" for her to download onto her phone when she woke up. Erin didn't think much about it, thinking that it might've been supposed for her sister to have. If it was free, why shouldn't she download it? It wasn't like she used her phone for anything other than talking and texting with her family. After Erin agreed to the Terms & Conditions on the install window that she didn't read, the app installed itself and started to run. Erin tried to open the app, but all she got was a prompt that said, "Please wait for an available user."
Now getting a little paranoid, Erin quickly got out of bed and made an attempt to look up the app on her laptop and see if she could remove it before it left her phone with a bad virus. After multiple Google searches for hours, Erin got nothing. There is nothing out there on the web about The CYC App or how it mysteriously got on her phone. Just when Erin decided to stop her searching and focus on getting dressed, she heard a *DING* from her phone. Looking at the notification showed that it was the CYC app with the message stating, "You have been selected. Please enjoy your changes. The first will begin shortly."
Cryptic message aside, Erin just closed the message and began to take off her sleepwear attire (top and panties) and made her way to the bathroom for a shower to start the day properly. Unfortunately, if Erin had taken her phone with her, she would've seen a more recent notification that said, "The first change has been selected by your user."
At that point, Erin was deep in her shower routine, and the discomfort that racked up within her has brushed aside as anxiety from the app. The uncomfortable feeling spread all around her but it mostly settled in her chest and butt.
It is quite facilitating how the human mind has a way to explain the impossible. Or how Erin manages to miss out on her transformation that came from the app. For example, if Erin didn’t have her hair in her face, she would’ve seen the room was getting bigger. That shrinking feeling that came with Erin's loss of height was considered to Erin to be just nerves. So while Erin’s mind was busy with thoughts about what to do about the app, her hands were also busy rubbing in the sudsy soap around her uncomfortable, shrunken body.
Soon enough, the taut feeling within her chest and butt begin to build up. The tightness has built up so much that Erin felt like it became much harder to move around. That is what her mind told her. In reality, all that titillation that was building inside of Erin was in fact her breasts and butt growing.
For once in her plain, simple life, Erin is finally getting the tits that she deserves. Not to mention the bonus of the extra curve below the belt. Too bad that Erin wasn't there to witness it, with her mind now thinking about what to do later today. The steady growth of Erin's bust and ass has been growing without their owner's awareness or attention. By the time Erin turns off the shower, she has lost a foot of her original height (4'8") and has gained an extra 100 pounds (with each new quarter now resting in her new asset). Erin didn't notice her new stature, her change of balance, or even how much she had been bouncing around. Instead, the only thing Erin focused on was trying to get her hair dry.
Meanwhile, in another part of the town, the new user of Erin Harrison was happy that they managed to make her into a short stack. But what should they change next for their new plaything?
