Sara, with two big(ger) surprises

I get up to answer the door while still just in my boxers. Whoever is waking me up during my lazy day will just have to deal with it. Although before I can register who I'm looking at, Sara shoves her way past me and into the room.

"Sara? What are you doing here so early? You know I like to sleep in on my days off." I whine to her as I turn to face her.

What I see is her standing there with her hands on her hips, staring at me and not saying anything. She's wearing leggings and her sweater from yesterday with her hair in a ponytail.

"Sara?" I ask, confused.

She sighs and says "We aren't having a conversation right now. Get it?"

What?...Oh yeah! Upon realizing I immediately lock onto her chest to see what she was getting at and totally no other reason. What I'm greeted with is her magnificent chest, if her chest were under a magnifying glass.

"Are you padding your chest or something?"

"No dumb ass, look." She says as she hefts one breast and lets it drop.

Holy shit, it worked.

"What the hell? When did it change?" I ask excitedly.

She started explaining while she paced a bit, "I don't really know. I got up to go to the gym today and my chest felt a little heavy, but I didn't really think too much about it until I tried to put on my bra. There is no way these are going to fit into any I own now."

"Well let's have a look at the app." I say as a grab my phone. She comes closer to look over my shoulder and I feel her newly inflated chest press up against my arm.

Upon opening, I notice the "My Girls" tab is now outlined with a glow so I tap it. Before the page loads we get another pop up.

Congrats on customizing your first girl! As you may have guessed, any girls you customize can be found here.
You can customize any mods you have on them, like awareness or otherwise if it's got extras.
Oh, also the range limit is removed so you can check on them from wherever, whenever.

"Neat." We both say simultaneously.

"You seem pretty okay with the fact that you just had your body changed by a magic app. Are you good?" I ask, a little confused and concerned at the same time.

"Yeah I'm doing fine so far. Finding out magic is actually a thing is pretty cool." She explains. "Plus I kind of always wanted a larger chest. I know I was already pretty big, I just wanted a little more and now I got them for free, and they're all natural to boot!"

"So long as you're fine." I click her profile.

Everything is the same as last time save for a few details. First off, her cup size is now listed as G with a couple extra pounds in the weight section to match, and the customization section now has "Cup Up" listed with two buttons to the right of it that say "Awareness" and "Repurchase - 8 gems." Upon seeing the price listed I glance up to the top of the page to see my gems listed as 24/100. I'm no math major but I'm pretty sure its supposed to be lower than that, even if my two purchases yesterday were free, but I'll work on that later.

"Press awareness." Sara demands. "Oh, and I swear to God, if I ever find out you tuned my awareness off for anything done to me I'll throttle you." A reasonable threat, but unnecessary.

I press the button and am met with several more buttons. Six in two separate rows. The first was labeled "Girl" and the second was "Everyone else," each with the same three choices: "Unnoticed," "Noticed," and "Normal." The only difference being that the option in the first row was locked to Noticed, and the second was set to Unnoticed

"Huh, no reason to worry I guess." Sara says as I ponder why the other options were locked, but before I could give it any significant thought another popup appears.

Sorry :(
We didn't expect anyone to go this route so quickly.
Typically settings both default to Unnoticed, but there's an exception.
Any modified girl that becomes aware of the app and its effects.
You guys seem to get along though so it shouldn't be a problem ;)

"Lucky us, I guess." I said with a chuckle.

"The magic app seems to have a fun personality." Sara chuckles with me.

"I don't think its the app talking. The messages keep saying 'we.' I think the developers are talking through pop ups." I reasoned.

"Whatever, don't want to think about it. Just set the awareness to Normal for my tits. I want to show them off without having to explain the sudden growth spurt." She requests, and I oblige.

Thank you again for reading.
I want to make these chapters longer to get to the fun part earlier, but I only have a limited amount of time to write a day and I work best writing each chapter in one sitting. It should start getting spicy next chapter, I promise.
