After completing all experiments ahead of time, I got permission from the teaching assistant and headed home early.

When I asked the TA if I could leave early, they gave me a look as if I was crazy, but after checking the perfect circuit and data, they let me go without any comments.

I quickly got to my studio apartment, changed my clothes, washed up, and lay down on the bed.

Due to studying late the night before, I was so sleepy that I immediately fell asleep.

"Hmm... Did I fall asleep? But where is this?"

A familiar scenery.

A space with continuous white, square walls, similar yet awkwardly lacking something compared to what I knew.

"It looks like a bathroom... but there's no urinal? Why am I floating? Is this an out-of-body experience? I'm not dead, am I?"

Trying to figure out the situation, it seemed like a women's bathroom as there were only toilets around.

Among several stalls, one had a woman sitting on the toilet, a beautiful woman with striking black hair.

Her clothes and face were familiar, almost like someone I had seen recently.

"What? Isn’t that Shin Ah-young?? Could it be...from the bathroom earlier!?"

"Haah♡ Ahh♡ Uhuhh♡ That feels good♡ Ehehe... not the clit♡ I’m going... going, going, going, goinggg♡♡"

No sooner had I thought that, Shin Ah-young moaned loudly, her waist bouncing as she climaxed.

Her lower body was bare, revealing her white thighs and slightly engorged red vulva explicitly.

Her heaving breath made her large breasts sway up and down.

It was the half-naked image of Shin Ah-young, something you'd only expect in dreams.

"Damn, what is this..? It must be a dream, right? It has to be since I'm aware of it, maybe a lucid dream?"

Thrusting...

"Ahh♡ It’s so hot....♡ Ahh... feels so good....♡ Uhhuh.."

"Who cares. Damn, this is so arousing. Shin Ah-young masturbating is such a rare sight."

As I saw the opportunity of a lifetime, I lowered my pants and reached for my already aroused cock.

Familiar ceiling.

Blinking...

"Ah, fuck, was it a dream? It was so vivid, too bad it didn’t last till I could masturbate just once."

Putting aside whether I could masturbate in a dream, I tried my best to recall the earlier scene.

"First, I need to imagine it as I remember, leaning back on the toilet seat with legs stretched out..."

Buzzz!

My phone rang abruptly, just as I was getting back into the mood.

"Damn, I never get calls, and now it rings... terrible timing."

As the mood was disrupted, I sighed and checked my phone.

A message I didn't want to read from the first line.

Subject: Customer Satisfaction Survey

Hello, Woo-jin Park. Did you receive your ordered product?

It’s been a week since your purchase, and we sent this survey to assess your satisfaction.

Respond sincerely, and a small gift will be rewarded!

~~~

~~~

~~~

Please write only the number from 1 (very dissatisfied) to 5 (very satisfied) and send it back to this number.

Have a great day!

'What is this, some kind of spam... from the site where I bought the vibe?'

I was angry that this kind of message broke the mood.

Just as I was about to delete it, one fact came to mind.

'Wait, it's been a week since I bought it? It's only been 2-3 days since the vibe... could it be...?'

'Was it sent by that mysterious seller? I have to respond diligently for a small gift... I have no choice.'

Such items must be sold by either aliens or people from the future.

I nervously looked over the questions, but as I read them, the tension drained away.

Do you like this product? 'Yeah, I really like it, 5 (very satisfied).'

How often have you used it over the past week?

Not used

5 times or less

6-10 times

11-15 times

More than 16 times.

'I couldn't use it that much because of being observed... 4.'

A few more silly questions followed, and as I swiftly scrolled down, finally the last question appeared.

★. Have you noticed any unique advantages of this product?

A meaningful and the only subjective question.

'Of course... they're asking about that?

I found out on the third day because of online classes, but if it weren't for that, I might still think it was just a pleasant onahole.

-Yes, I roughly know. It's connected to an actual pussy, right?

'This should be enough. Send.'

Whirrrr!

As soon as I sent it, it vibrated immediately. I checked the text message.

Title: Thank you for participating in our survey.

Based on your responses, it seems we will have good feedback.

The promised gift will be dispatched by courier and arrive tomorrow.

Thank you for responding to the survey.

Have a great time.

"What, they've already sent it? That was fast... but what kind of thing would such a seller send?'

No matter how much I thought about it, it seemed unlikely to be an ordinary item.

After finishing these thoughts, I pulled up my pants that I had lowered earlier and sat down at the desk.

Between enjoying something in the lab earlier and the survey message, I didn't feel like doing much else today.

'I guess I'll just do my assignment and play games until bedtime. Hope something fun arrives tomorrow.'

=====

The next day, the package arrived.

It was a smaller box than I expected, so I was slightly disappointed, but I immediately brought it to my room to open it.

"What's this, a pamphlet? A manual?"

It was a small sheet of A4 paper folded once horizontally and once vertically,

It contained something like a travel brochure.

"The first page says... wireless onahole instructions?"

Hello.

Thank you for purchasing our wireless onahole product.

This product is a masterpiece and an experimental work that our company has put great effort into creating.

It has the capability to replicate the taste of a real woman’s genitals, as you responded in our survey.

While it is still an initial model and does not have the capability to completely replicate any woman you imagine, it is possible if the person is someone around you or someone whose image strongly remains in your mind.

"It's amazing that this was created. Did they kidnap an alien or something? Next page."

The default setting when it was first shipped was set to Ms. Shin Ah-young, whom Mr. Park Woo-jin had the highest affinity for, If you wish, the onahole can change to match any other woman you imagine.

However, each woman has a gauge, and points accumulate with 3 points at the woman’s climax and 5 points at ejaculation inside.

As you collect points and reach 100, 200, 300 points, each of the locked functions will be unlocked.

To put it simply, you can think of it as the synchronization rate going up.

Since it's your first time, I'll let you know that the voyeurism function unlocks at 100 points.

We hope you have a pleasant experience exploring further.

"Are there more features? Voyeurism... Next page."

We hope you will help us collect data and have a pleasant life.

*Please download the app from the address below.

https://^&)(#)(@)^)(@#&$(!&@(#)^)^T$(*&@(&)$

The last page only had one internet address left along with a final greeting.

It looked like a phone virus address, but my curiosity was stronger.

"Shall open it? An app, huh.. Seems like a familiar setup."

Upon accessing it, an app was automatically downloaded.

After installing it on my phone and opening it,

[Shin Ah-young]

Currently, Shin Ah-young's gauge is at 86 points.

Age: 22

Height: 168.3 cm

Weight: 49.8 kg

Three sizes: 97 - 66 - 95

Disposition: Masochist

Weak points: Clitoris, G-spot, Cervix, anal

Favorite position: Doggy style

I was stunned at first glance.

"Wow, what the fuck? Looks like an app I've only seen on Hitomi, maybe it'll have a hypnotism function or something later?"

Whether the information is real or fake, the fact that there's technology to make such a device made me suddenly believe in it.

I refocused and read the information about Shin Ah-young slowly from top to bottom.

The breasts and ass, which were huge even with a casual glance, were beyond imagination when seen as data.

It was really unexpected that she was walking around with such things and still weighing less than 50 kg.

"Isn't this just blatantly asking to be fucked?"

Despite seeing the unbelievable specs over and over, I read them several times.

After storing them perfectly in my brain, I checked to see if there were any other functions, but only information was there, nothing else.

Still, it's something.

"Since it says the voyeurism function unlocks at 100 points, I guess I'll just ejaculate inside a few times to hit it right."

I only needed 14 more points, so I thought about filling it up right away, but I held back since I seemed to have troubled Shin Ah-young a lot today.

She needed some time to rest for a good reaction and mental recovery, so I put the onahole down again.

"Today, I should also rest while doing my assignments in advance."
