< Prologue >
The onahole moves on its own.
What kind of crazy talk is that, you ask?
Well, it's not like it's dancing and moving by itself, but when you thrust into it, it produces love juices and tightens in a way that feels truly alive.
It may be hard to believe, but let me explain how this came to be.
To briefly introduce myself, I'm a typical loner who went to all-boys middle and high schools, then engineering college and the military, and am now returning as a 3rd year student.
Naturally, I'm in the tearful situation of having no women, let alone female friends, around me.
After living as a virgin and masturbating until age 24, I became curious about how a vagina feels and bought an onahole.
The internet says you experience an incredible moment of clarity when washing it, but for someone like me who was already tired of using my hand, it was like salvation.
The feeling was on a whole different level compared to my hand, and I became addicted to masturbation, using it more than 3 times a day.
Before long, the entrance and inside of the onahole became worn out.
Seeing bits of silicone tear off when I pulled out my penis, I could tell its lifespan was over.
"Sigh... this feels good but the durability is poor. It's already broken."
I said that, but I actually knew the truth.
An ordinary onahole couldn't withstand my 20cm penis for long.
"Guess I'll have to buy another one... maybe I'll get a sturdier, larger one this time."
After thoroughly washing my penis in the bathroom, I sat at the computer and searched.
"Hmm... this one has bad reviews... this one's interior is too small..."
Scroll... scroll...
As I scrolled down, a photo caught my eye.
"What's this? I've never seen it before, is it a new product?"
I clicked on it.
There was a large onahole that recreated a woman's upper body and thighs, though without a neck, arms or legs.
I scrolled down to see the detailed description.

Anyone could see it was exaggerated false advertising, but the arousing photo and tempting description made me consider it.
"The onahole changes itself? Does that mean the inside will adapt to my penis if I use it for a long time?"
Since I'm a loner with nowhere else to spend money anyway, I had some savings in my account. After about 10 seconds of deliberation, I clicked the purchase button.

The next day
A large box was delivered to my door, and I eagerly tore it open with excitement.
"Wow, I couldn't tell from the photos but it's huge in person."
It was an enormous size, matching a real woman's body 1:1.
Huge G-cup breasts protruding from the chest with pink nipples, a slim waist, and a vagina and anus that looked exactly like in porn.
Just looking at it made my penis get hard, so I immediately took off my clothes and got some lube.
I opened the cap and sprayed lube on the vagina, gently spreading it inside. At that moment...
"Kyaa!!"
From some distant apartment.
A high-pitched woman's scream could be heard.
< Chapter 1 > 001. An Onahole with Many Functions
Squish... squish...
As I diligently applied lube to the onahole, I felt the inside of the vagina move slightly.
'Did the inside just move? Maybe it's my imagination. The inside feels a bit warm too.'
I sensed something strange but just brushed it off as "It's expensive so it must have some features," not thinking much of it.
It was my first time using a large onahole after all.
After thoroughly lubricating the inside, I positioned myself and inserted my penis.
The feeling of it being slightly warmer than human body temperature and squeezing me made me gasp in amazement without realizing it.
It felt better than any onahole I'd used before.
I inserted about 1/3 of the way in, but the tight inside made it difficult to go further.
"Is it because it's the first time? It won't go in past here. I should add more lube."
Pop!
When I pulled out my penis, there was a sound like uncorking a bottle.
The 20cm was probably too big for the onahole, as the entrance didn't fully close even though it was new.
I squeezed lube directly into the gaping hole and inserted it again. Unlike before, it slid in smoothly, making me moan involuntarily.
It sucked in my penis as if the vagina were alive, and each fold of the vaginal walls rubbing against me felt like I could cum at any moment if I wasn't careful.
I was surprised that yesterday's advertisement wasn't false after all.
Thinking I should leave a 5-star review later, I continued moving my hips.
Squish squish...
Lewd sounds echoed through the room, and before long I felt close to climax from the incredible tightness and suction.
Not holding back, I came immediately. At the same time, the inside of the vagina clenched tightly and started convulsing.
The pleasure was on a whole different level compared to my usual onaholes, and I felt like I ejaculated more than usual.
"This one was really worth buying. I can't believe something like this exists..."
Despite cumming once, my penis was still erect. I flipped it 180 degrees to put it in a doggystyle position.
I thrust into it vigorously, admiring the rippling buttocks and twitching anus.
I could feel the tight inside stretching around my large glans as I pushed forward, and the pressure squeezing me as if begging me not to pull out when I withdrew.
Compared to the small onaholes where I just had to move my hand, this full-body onahole consumed more energy.
After about 10 minutes of mindlessly thrusting my hips, I came again.
My body went limp as if my energy had been sucked out by a succubus.
After enjoying the long afterglow, I pulled out my penis and rested while drinking some water.
When my strength returned, I picked up the onahole and headed to the bathroom to wash it.
It was too big to wash in the sink, so I had to use the shower.
Shhhhhh
Seeing the strong stream of water, I turned the handle and waited for warm water to come out.
When it reached the right temperature, I held the onahole under the stream.
The wide spray of water allowed me to wash around the hole all at once.
When the water hit the clitoris, I felt something twitch.
But I didn't think much of it and inserted my hand to scrub the inside, washing away the semen and lube I had left behind.
I couldn't tell when just inserting my penis, but as I rubbed with my fingers, I could feel the internal structure well.
There was something bumpy on top, and I could tell the vaginal walls were curved and had many folds.
"Wow, they really paid attention to the internal details too. I'll go write a review right after washing this."
After thoroughly cleaning it and wiping off the water, I accessed the site where I bought it.
And a message popped up:
[This page cannot be displayed]
What? The page disappeared after just one day?
Did it sell out that quickly, or was it a scam?
All kinds of thoughts went through my mind, but it wasn't a big deal.
It was quite a good onahole by my standards, so I didn't care anymore.
I decided to just forget about it and started working on the lab report due tomorrow.

The next day
The mandatory lab course for engineering students.
The worst class that takes up 3 hours for just 1 credit, which you can't graduate without completing.
On top of that, there was the hassle of submitting pre-lab and post-lab reports every week.
Going to school to do the actual experiments was annoying, but there was one good point.
Shin Ah-young, rumored to be the prettiest girl in our school.
Being in the same lab section meant I could see her for 3 hours straight.
No matter how tough the experiment was, seeing her face made all the fatigue disappear, so it wasn't so bad.
After arriving at school and sitting down, I was looking over the lab equipment when Shin Ah-young walked in.
She usually went around with a bright, pretty smile, but today she looked gloomy and depressed.
Judging by how she was rubbing her lower abdomen, it seemed like she had eaten something bad or it was that time of the month.
'I should be careful at times like this. Better not hang around her.'
As her expression darkened, classmates around started asking if she was okay.
"Ah-young, are you not feeling well today? You look a bit down."
"Did something happen today? Are you sick somewhere?"
"Ah... no, I'm fine... It's nothing."
She didn't look fine at all, but Shin Ah-young forced a smile as she answered.
Though her complexion was dark, her appearance was enough to light up the lab.
Breasts so large they couldn't be held in one hand, a slim waist.
And wide hips and buttocks that looked like they would burst out of her jeans, with slender legs.
The title of perfect body was not an exaggeration.
That's not all.
Flowing black hair, large jet-black eyes, long eyelashes, a high nose bridge, small but plump lips.
Her body and face created an incredible synergy.
I could feel my penis twitching under my pants, but showing it would mean social death, so I desperately hid it.
As I was secretly stealing glances at Shin Ah-young's back, the TA came in and the experiment began.
"Today's experiment is to ~~~ by measuring ~~~ to ~~~. Please begin."
In the middle of the experiment, I noticed Shin Ah-young going in and out frequently.
It really did seem like that time of the month.
"Good work everyone!"
As the long experiment ended, I started packing my bag.
After quickly finishing up, I was about to leave when I heard talking behind me.
Listening closely, it was classmates asking Shin Ah-young to get food together.
"Ah-young, want to get food together later? A tasty new place opened near campus."
"Sorry... I have some things to do today... Let's eat together next time."
"Oh really? Okay, see you next time then. Bye!"
I wasn't very interested, so I decided to go straight back to my apartment.
Right now, my mind was filled with thoughts of using the onahole while imagining Shin Ah-young's body.
Beep beep beep beep
Returning to my room, I tossed my bag aside and immediately looked for the onahole.
I laid it on the bed and started roughly groping the firm breasts.
'I wonder if Shin Ah-young's breasts are about this size? They looked huge and soft. Are her nipples pink like this too?'
Suddenly curious, I straddled its stomach and inserted my penis between the breasts.
Mine is big too, but it was amazing how it disappeared completely between the G-cup breasts.
I sprayed lube on my penis and rubbed the breasts to spread it everywhere.
Once it was sufficiently coated, I started moving my hips.
Each time I rubbed, the tip of my penis got caught between the breasts, but thanks to the lube, I felt a new pleasure.
'Oh... so this is how it feels... This is pretty good in its own way.'
In the middle of rubbing, I felt something on my palm.
I took my hands off for a moment and saw that both nipples were erect.
The nipples were as large as the enormous breasts.
How could I resist seeing something like this?
I immediately started playing with them, pinching them between my thumb and index finger.
After about 5 minutes of that, I started to feel close to climax, so I moved faster and came between the collarbones.
Throb... throb throb...
Leaving the reddened breasts with handprints on them, I looked down.
Unlike yesterday, the clitoris had peeled back its hood and was exposed, and the entrance looked somewhat wet.
I felt it was even stranger than yesterday, but the erotic sight made me overlook it.
'Whatever, as long as it's arousing. Let's just fuck it.'
I brought the lube and sprayed it on the clitoris.
When I inserted the dripping liquid into the vagina, the inside was already sticky and wet.
I immediately got into position and thrust all the way in at once.
Then I felt something touch the tip of my glans.
'Something touched the tip - is this the cervix? They even implemented this.'
Curious, I tapped the cervix with my glans, and the inside clenched tightly and convulsed.
I'm not sure if it was squeezing my penis as if begging for semen in the womb, or if it was trying to block me from entering somewhere I shouldn't.
"Does it have a vibration function too? It keeps squeezing and trembling."
After thrusting mindlessly, I came once, twice... How much time had passed?
Eventually I started to feel like my balls were empty, so I pulled out my penis.
Looking down, the sheets were soaked, and frothy white liquid kept leaking out of the vagina.
"Did I really cum this much? I should wash this and do laundry right away."
I tucked the onahole under my arm and went to the bathroom to wash it, but it seemed droopy from overuse.
"I can't buy this again, maybe I should have been gentler..."
I thoroughly washed off the dried semen on the chest area and the fluids that had leaked from the vagina with warm water.
This time I wiped it carefully, removing all moisture with a dry towel.
Hoping it would last a long time, I stored it in a well-ventilated place and went to do my other tasks.
