A Date with Eunseo

***

The updated feature was exquisitely perfect.

Semen Control had various properties, but the most crucial was the ability to adjust sperm motility.

In other words, I now had a body that could freely decide on contraception or impregnation.

'I've ended up with a passive ability that fantasy harem protagonists get.'

And not just that.

Semen Control was, in a nutshell, the function to impregnate Kim Youngae.

Due to her innate infertility and stress-induced neuritis, Kim Youngae's fertilization and implantation process was prolonged, making pregnancy impossible without exceptionally high-motility sperm.

According to the doctor's opinion photo she'd buried in her chat history, even the healthiest sperm gave her an extremely slim chance of conception.

'If I max out sperm motility with Semen Control, I could probably push her pregnancy odds to 100%.'

If she got pregnant with my child, given Kim Youngae's personality, she'd become my woman in an instant—no more need for "conquest" talk.

Of course, it wasn't a decision to make lightly; it required deep deliberation.

Having Kim Youngae was great.

But could I accept becoming a father?

A child carrying my blood, my genes.

Thanks to WeLike's reality correction, I now possessed looks in the top 3% of 100 people.

But would that appearance correction transcend genetics?

My parents had given birth to an utterly ordinary me.

If I were a bit more selfish, I might have resented them.

That thought made me hesitate on impregnation.

I'd never seriously considered becoming a dad.

In other words, I wasn't ready to be a father.

If I wasn't going to knock her up and ghost, I had to decide with utmost caution.

Suddenly, intuition struck.

Becoming someone's dad would be a major turning point in my life.

'Whatever. For now, I'll just be happy that I don't need to worry about contraception anymore.'

It was one less thing on my mind—perfect.

First, I used the hefty GP stockpile to update Kegel Trainer once more.

'Oh. A feature straight out of Japanese ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠manga.'

I'd have to experiment to gauge the addictiveness and arousal effects, but it was plenty satisfying.

Just reading the description sparked lewd, fun ideas, nearly giving me a hard-on.

Lust reacted immediately, spawning a quest.

The very first desire I'd harbored when acquiring the Desire Fulfillment App—my greatest craving.

Lust spat out quests at the slightest provocation.

'I've got a mountain of GP thanks to Lust's quests.'

I updated Kegel Trainer once more.

Since Lust was the biggest driver of my growth, more cock-related features were always welcome.

In short, it let me erect my spongy, involuntary cock without arousal or bend it left and right at will.

Sex-related features boosted both GP absorption efficiency and lust fulfillment.

'One more upgrade wouldn't hurt.'

I tested the feature right away.

Even without Lust stirring, my cock hardened instantly and twitched left and right at my command.

Thinking "shrink" made it smaller; "grow" made it bigger.

'It's a total magic wand.'

There were limits to resizing, but it was impressive enough.

Next, I willed other changes.

The glans reshaped at my whim, then tiny protrusions sprouted across the shaft.

Visually grotesque, but perfect for driving a woman to ecstasy.

The name Woman's Cock clicked.

Using this aggressively would amplify her pleasure.

'GP absorption efficiency will skyrocket.'

I checked my GP after Kegel Trainer updates.

Still about 1,000 left.

'I can leave 100 as buffer.'

What to upgrade next?

I chose WeLike—highest utility per investment so far.

'Huh?'

I'd uncovered a limit of the Desire Fulfillment App I hadn't known before.

'Why the limit?'

The app reacted to my thought, popping up an explanation.

Reading the ensuing explanation popups, I understood.

Added features reflected the app's inherent traits and users' accumulated desires.

For example, I'd updated WeLike, a photo editor, to gain appearance correction—merging editing traits with users' desire to enhance their photo looks.

'Popular apps yield useful features because they hold more accumulated user desire power.'

An old question answered.

The 3-feature cap per app stemmed from extracting up to 3 desires from users.

'If fewer than 3, the features are underwhelming.'

In essence, update features depended on the magnitude and direction of accumulated desires.

I grasped the desire power concept fully.

Continuing, I learned about variability.

Repeated updates on one app made features increasingly potent, amplifying Earth's impact.

Thus, required variability grew, capping simple updates at 6 per app (1 per feature max).

'In ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠game terms, variability is like system resources.'

Felt like 6 resources allocated per app.

'Quest rewards or app enchants unlock extra resources; plain GP spends don't.'

I tallied past updates:

Except InBody Care and Kegel Trainer, all had 3+ features.

'No need to update existing apps unless adding new ones.'

They were satisfying as-is; wasting GP without need felt pointless.

'Might as well try app patching.'

Like the new App Enchant from the tutorial end, patching might yield useful features.

Affirming intent brought a new popup.

What feature to add?

I pondered briefly.

'The most pressing issue is... unlocking new app updates freely.'

GP stockpiles mean nothing without new unlocks for strengthening.

The app reacted.

I waited ages, but it just looped loading, so I closed it.

'It'll work eventually.'

Too much to check right now to wait idly.

I pulled up Kim Youngae's profile on my phone screen.
