The Tenth Night: Tsumakari - Kurotama

Author: [I apologize for the delay in updating. Also, as my creative inspiration has returned, I would like to continue with updates. I am looking forward to your feedback.]

The next yokai to appear at the next Tsumakari is called "Kurotama".(Black Ball)

I've never heard of this monster before.

The appearance of this yokai, as depicted in ancient documents, was like a black and round shadow-like thing, just as its name suggests. (TL/N: Maybe it's looks like Susuwatari in Spirited Away, but floating, foggy and bigger. Image of Susuwatari here)

There are few descriptions, and they vary from "encountered by a traveler in the mountains" to "appearing from the sea", while others claim it "appeared from the sea or even inside people's homes while they were sleeping."

One common feature is that its form is unclear and difficult to see clearly. It also has the ability to absorb human energy.

Even my wife doesn't know much about it. Is this an original yokai from this world? Anyway, if we can see the real thing, everything will become clear.

For now, I have decided to wait for him (it) to appear at the Tsumakari."

But seriously, how does something that seems to be just a black sphere from its name have sex?

And so, the night of "tsumakari" had come.

And as for the "Kurotama," it didn't so much "visit" as it just appeared inside the house.

Before they knew it, it was floating in the tsumakari room as if it were completely natural.

Seeing it with my own eyes, I can't quite describe what it was like...

It wasn't so much that "it" was there as that there was "nothing."

It was like a black hole opening up in space, with no clear outline or even size.

If you kept staring at it, your head would start to spin...

... It felt similar to that sensation when you get dizzy and everything goes dark before your eyes.

With dizziness, you feel sick and your vision goes dark, but this is the opposite: looking at the black void-like space of the Kurotama makes you feel sick.

The cause and effect are reversed.

Thinking about this made me feel like I understood what exactly the Kurotama really is: In other words, its true form is vertigo or dizziness - something along those lines.

It's an embodiment of sudden sickness where you suddenly feel unwell and everything goes dark before your eyes.

Or perhaps such imaginings have been read by some entity on 'the other side' and given physical form; maybe that's what the Kurotama is all about.

Even still, how does one interact with a black ball? Why do people interact with them? There's no way to know for sure but while thinking about these things my wife who had been sitting across from me, suddenly fell to the side, still sitting, as if the sound of the fall was swallowed by the black ball.

It seemed she had been affected by the Kurotama.

I hurriedly went over to her side,

Fortunately she landed on top of our futon so I put her back into bed right away and the black ball shrunk a little before hovering above her. And then it descended upon her body, sticking to her like glue.

It seems that the "Tsumakari" by the black ball has begun.

Although there was no change in appearance of the black ball clinging to my wife's body, she began writhing and moaning as if she were having a nightmare.

When feeling unwell, one naturally has nightmares and tosses and turns in bed. I suppose that's what's happening to my wife now. The Kurotama has the ability to make sleeping people feel ill and show them nightmares like a demon of dreams. Sweat drips from my wife's face as she tosses and turns repeatedly.

I wonder if she's okay. Although I was worried, the note in the old document said "do as the Kurotama commands," so I just watched over her.

"Ah... ahn"

Eventually, there was a change in my wife who had only been having bad dreams before; gradually mixing moans with something seductive. Even her writhing body became sexy. Her yukata came undone, exposing her ample breasts with cherry-colored nipples becoming increasingly hard to see clearly. Her slender bare legs stretched out from under the large rolled-up hem of her yukata, gradually spreading apart while moistening between them as two arms were extended towards empty space as if welcoming something.

"Mmm... Ahh... Aahhn..."

Before we knew it, it seems that the nightmare had turned into an erotic dream-like state similar to an incubus which is also known for its ability to show erotic dreams through black balls or demons of lusts.

I see… It makes sense that they would make someone possessed by showing them lewd dreams.

Is this what sexual intercourse with a Kurotama is like?

"...Ahh! Aaahh! Ahnn!"

The shadow of the Kurotama clinging onto my wife's body becomes more vague by each passing moment. Strangely, through the darkness of the shadow... or rather, through the darkness itself,, my wife's physical form can be seen clearly as if it was emitting light itself.

It looks like she is being violated by someone invisible within darkness.

As soon as I saw how unclearly defined shape of shadowy figure on top of my wife began looking human-like for a moment, something flashed in my mind.

"There was a similar yokai in the world I used to live in...I think it was called Kurobouzu."

Kurobouzu, as its name suggests, is a black monk-like figure or just a mouth. It's said that it's hard to see its true form clearly with human eyes. It appears at night and sucks on the breath of sleeping women or licks their mouths. (TL/N: Image of Kurobouzu here)

Although it is a minor yokai, thanks to appearing in certain popular anime about yokai, it has gained some degree of name recognition.

However, even though the anime depicts Kurobouzu as having an unmistakable black monk-like appearance that clearly different from the one in front of me...

However, the original Kurobouzu can also be considered a similar creature if we think of it as a yokai born from nightmares during sleep.

Come to think of it, there were people who thought that the "Night-crawling Terror" was also transformed into a yokai.

Indeed, that is the current situation before me.

Whether the fear belongs to the sleeping woman or to the man who witnessed it...perhaps even to her husband, we do not know for sure. However, what is certain is that there are similarities with Kurotama.

"No...stop...ahh...no, please..."

Within the darkness of Kurotama's realm, my wife's lewd writhing grows more intense. While I have begun to understand part of its true nature, this has only led me to another question: "Who exactly is she being held by in her dream?"

"Ahh...yes! It feels good... I'm getting turned on... Ngh..."

As my wife continues to writhe sensually before me, I ponder whether this experience will ultimately prove beneficial or detrimental for her. Until now,

she has always taken such encounters with yokai in stride - whether due to her role as a shrine maiden or simply because they were creatures beyond human morality.

Is it because she is "fulfilling her role as a miko" or is it because "it's just a yokai"?

Even when engaging in sexual acts with them, she rarely showed any signs of hesitation or guilt.

But now, within this erotic nightmare, I sense both reluctance and shame emanating from her along with pleasure - emotions which had never surfaced during our previous encounters with yokai. And then from between my wife's lips:

"No...please stop. I have a husband."

"Ah...even though I shouldn't be doing this...yet... no..."

She begins muttering deliriously under her breath

The one embracing my wife in her dream is not a yokai, and certainly not me, was he perhaps someone unknown? Then, who is it?

Is my wife embracing a stranger?

Or could it be...

A feeling akin to anxiety begins gnawing at my chest, even as I find myself captivated by the sight of my wife drowning in pleasure mixed with shame and guilt - a sensation unlike any I have ever seen before.

I'm coming... mmm..."

The shadow of immorality etched on my wife's body was more lascivious and beautiful than ever before, revealing a new side to her.

She writhed in response to the caresses of an unseen partner, using her body wantonly. She moved her hips eagerly as she was penetrated.

I felt both jealous and excited by this unknown man who I couldn't see.

"It feels so good! Even though it's wrong, I can't help but feel it! More...more...ahh!"

As my wife spoke deliriously, any feelings of guilt or shame gradually faded away. Instead, she actively sought pleasure from sex.

Her movements became increasingly intense until I could tell that their dream-like lovemaking was nearing its end. My wife's arms crossed lovingly in mid-air as if embracing someone invisible.

Meanwhile, my own arousal had grown significantly without me even realizing it.

"Ahh! Ahh! Aaaahhhh!"

And with unbridled sounds of pleasure, my wife reached climax right before my eyes

Not only that, even though I couldn't see him, I could clearly sense my wife being ejaculated into her vagina by her partner inside her dream.

Having allowed another man besides myself to release his seed inside her womb, my wife fell into a peaceful sleep with a blissful expression on her face. For just a brief moment amidst the silence that followed, all I could hear were the satisfied breaths of my sleeping wife and the pounding beat of my heart like a ticking clock...

Thump thump thump thump...

After counting up to ten beats or so,

A certain name slipped out from between my wife's lips:

"...-kun.

That was clearly a human name, and a male one at that.
