John Doe, 20 Year old College Junior

"Welcome back," I say nonchalantly from the couch as I hear my girlfriend, Annabelle, enter our apartment, "how was the drive?"

"Terrible, they still haven't fully cleared the snow on the main highway down." She replies.

I check the time, 8:37 PM, and ask, "Any plans tonight then?"

"Unpacking, then sleep." She replies taking her coat off. I watch her as she does so. We started dating our freshman year. Both of us were fairly nerdy in high school, and in college we were both **** to get into a relationship, both of us being better looking than a lot of the people in our Computer science course, it was natural for us to get into a relationship with each other.

Annabelle is a little on the tall side, standing 5'11", with a flat chest and ass, with neck length ginger hair, and freckles on her face, with blue eyes. Not that I'm one to talk, being slightly pudgy with glasses.

As she hauls her suitcase back into the bedroom, I get up and go into the office space, and start playing video games as she unpacks.

Eventually I hear the shower going, and then not much later, it sounds like she's gone to bed.

After playing some more games, I go to check my phone before leaving the office to go to bed, but when I unlock it, I'm greeted by an unfamiliar and alarming picture.

Instead of going to my home screen, I get a full screen pink background with a Heart in the center made by two pointed tails, inside the heart in fancy writing it says "Custom Girls".

I almost go to hold the power button on my phone to reset it, but what good will that do if its a virus... Instead I resign myself to at least checking out whatever this is before I factory reset my phone so I can maybe get some kind of idea where the hell I got the virus to begin with.

When I tap forward I'm greeted by a small wall of text.

"Welcome to the Custom Girls App! You're one of a select few to have access to this application!"

After reading that line, I almost sigh. Its almost certainly some kind of scam, next its going to ask for money or something along those lines. I continue reading.

"This application is completely free and operates on powers beyond normal human understanding. As you gain levels in the app, more will be explained to you, but for now, what you need to know about are 4 things.

1. This application is useful for modifying the women (or men in some situations) to make them more palatable to you, the user.

2. There are two numbers you need to keep track of. First is your gem count. Gems are used to modify women. You can earn gems through achievements, and get 10 gems per day. Those 10 gems per day are intrinsic to your power, that amount will go up as you level up. The second number is your level and by extension the experience in it. Unlike other applications, your level doesn't only go up. Right now, you're level 1, with 5/100 experience. At level 1 your experience depletes by 1 every day, if it reaches 0, the app will be removed. At level 1, experience can only be gained by you, the user, having orgasms. You get more xp the more aroused you are at the time of orgasm.

3. Only you, the user, are allowed to operate this app. If someone else attempts to, they'll be warned, and if they continue, they'll be punished. Punishments drain 50% of your current level's maximum, so try to be careful, that said, sometimes punishments can be fun ;). They'll be put into a holding state until you select the punishment from a set of 3 random choices.

4. The application in its current state at level 1 requires you to be within 10 feet of any available women to add them to the application. Women in the app by default are unaware of changes made to them. This can be turned off if the user wants. All other people will also be completely unaware of any changes, and for now, this cannot be turned off."

When I read through all that, I tap again on the screen, and I go to a menu page with my level and 10/100 gems listed. There are a few grayed out tabs, a tab labelled "Custom Girls", and a tab labelled "Nearby Girls", both of which when I tap them, are empty.

Alright, well, I guess if I'm checking everything, I should move closer to Annabelle, and see if it sees her in the app. If it does, it likely means its infected her phone too, and its connecting between devices and using gps.

I go into our living room and get up to the wall bordering the bedroom, and sure enough Annabelle shows up in the application. I tap on her, and the app asks if I want to make her a custom girl. I hesitate briefly, before realizing, its not like the app hasn't already infected her phone. We'll have to reset it anyway.

When I add her in, a symbol appears by her name in "Nearby Girls", and when I go to "Custom Girls" She's now in that tab. When I tap on her name there I'm presented with a bunch of info: Age-20, Cup-A, Butt-flat, Height-5'11", IQ-136, ...

There was a whole lot of info in there, from medical info to favorite color. Damn, that's likely every piece of info that google has ever collected on her. Is google behind this? Amazon? Jesus.

There is a single button colored in labelled "Body Modifications" and a bunch of grey buttons. If I tap on "Body Modifications" then I get another set of buttons, where again only one is not greyed out labelled "Normal". Well, that implies at least one other button is abnormal.

In this one there is a scrollable list with headers.

Reading all the options, I start to get hard, and begin thinking more with my dick than with my head. I've always wished Annabelle had some tits (and ass!) that I could play with outside of it being straight pussy play. I tap on increase cup size, and affirm the choice. My gem total goes down to 8/100, and the cost of Increase cup size goes up to 4, and decrease goes up to 2.

I tap it again, and the gem total goes down to 4/100, and the cost is now 10 to increase and 5 to decrease it.

I go back to Annabelle's profile, and see that her profile now says C-Cup instead of A-Cup.

Feeling myself getting hornier at the thought of making Annabelle into my personal big-titted slut, I pull up some pornography with big busted red-heads, and begin jacking off.

After a little while, I cum into a tissue and go to dispose of it, feeling the normal shame I would from jacking off while my girlfriend sleeps in the other room, but feeling really good before that.

I open the app back up, and am slightly surprised to see my xp has gone from 5/100 to 15/100.

Alright, this is some weird google thing then, they tracked I watched porn, and gave me XP.

Feeling a little tired, I go into the bedroom, and crawl into bed, while I lay there for a bit, Annabelle rolls over and curls up against me.

I feel something out of place against my arm. My eyes haven't adjusted yet to the dark, but my curiosity is peaked, so I lay there awake until my eyes adjust, and I rub them multiple times. Annabelle has tits. Not huge tits, but firmly a c-cup. Am I asleep already? There is no way the app is real is there?

Oh god, I almost deleted it, but forgot after I masturbated. Was I saved by that? If its real, that's wild. I roll over and grab my phone. 11:36PM. I lie and wait.

11:57, 11:58, 11:59... 12:00AM. I open the app. 12/100 gems.

I make my way to it, and spend the 10 gems on Increase cup size again with one hand, while keeping my other arm between Annabelle's now existent tits.

I focus on my other arm, and feel a bit more mass envelope my arm. While I wait for my eyes to adjust again after looking at my phone, I start to feel my dick stir again.

Her tits are definitely bigger now, but they're a little... droopy? I go back into the app, and purchase the firmness for 2 gems, the new cost going up to 4 gems for increase.

They're still a little droopy, but they've got more defined shape to them now.

Shit, now I'm really hard. I get out of bed, being careful not to wake Annabelle, and go back to the office, and begin beating off again. This time I don't even pull porn up, instead getting off on the power and the idea of my now D-cup girlfriend. Oh fuck, and she isn't even aware of the change, neither is anyone else.

I cum again, this time much faster than before, and more powerfully, even though I just came a while ago.

The app now says 35/100 XP.

Fuck, what else can it do when I level up? I keep the app open and begin browsing the web to look for anything related to it, and it turns up nothing. Just thinking about it though, I start to get hard again, but start browsing for some porn to help me get off. Every so often, if I find a new porn site, or a new source of my general kinks, I get hard a lot and can cum over and over, although from here on out, most of the cum is going to basically be watery, or dry.

I keep jerking it for a few hours, before eventually basically passing out at my desk, 65/100 xp.

When I wake up, I'm startled for a moment. I'm at my desk...

The app! Where's my phone...

I look on the desk, and don't see it, I go to look around the room, and see Annabelle standing slightly beside and behind me, holding my phone, zoned out.

"Uh, Annabelle, uh, what're you doing." Is all I can say, panicked she's seen the app.

When she doesn't respond, I slowly get up, and go around to check my phone. On screen there's a whip with big words_ Punishment Time! _on screen.

Shit. Fuck. I didn't close the app, and she probably was wondering what the hell I was doing asleep at the computer... with my dick out... Ok, not a good look.

I tap the app, and a mini slot machine starts spinning with weird symbols flying by quickly. As I watch the symbols, I can make a few out. One looks like lips, another maybe a vagina?

After a few minutes, the wheels slow down, and settle on 3 symbols.

The first symbol: A heart with two things coming off the side?

The second: A thought bubble.

The third: A dick.

Underneath each one there is a description:

First: Hyper-fertile: The punished becomes hyper-fertile, guaranteeing pregnancy if cum gets into their vagina.

Ok, gonna pass on that for now. I'm in no position to be a dad. That image must be a womb?

Second: Dirty Thoughts: The punished develops a very sexualized mind, always taking things to dirty places.

Not terrible, it could get old though.

Third: Cum addict: The punished develops an addiction to the user's cum, and must get it into one of their holes at least once a week, or they get withdrawals, they are aware of the withdrawals and addiction, but will act like they've always had it.

Well, if I'm going to make her into my sex toy anyway, may as well do that right?

I tap option 3.
