The Shadow Beyond the Window

How long had I been moving my hips mindlessly like that?

At some point, the finger circling my entrance pressed deeper, almost as though it was trying to burrow inside. Every time I pulled my waist back, the pressure grew stronger little by little—

And then suddenly, the moment my finger finally slipped between the folds—

My vision flashed white.

“Haah!”

At the same time, my cock twitched violently.

The sharp pleasure shooting from both nipples mixed together with the sensation below, completely scrambling my thoughts. I trembled uncontrollably, panting over and over again.

Only after several moments did my breathing gradually steady enough for my mind to clear.

And then I realized—

My middle finger was already buried nearly to the second knuckle inside me.

“…Nngh.”

The tight inner walls gripping my finger kept twitching helplessly around it.

Considering I’d already climaxed once, it wasn’t strange for my body to react this way.

Still, maybe because I could feel everything so vividly through my finger, my cock slowly hardened again.

“……”

I’d already put it in this far.

A little deeper wouldn’t matter now.

If I’d stopped before crossing the line, maybe things would’ve been different.

But now that I knew pleasure could come from here too, there was absolutely no way I could stop.

Slowly lifting my collapsed waist again, I pressed my nipples harder against the bedding while carefully pushing my finger deeper.

“Haa— uht.”

Maybe it was because Geum Seo-yul existed in a BL novel world—

Or maybe this body was simply abnormal—

But whether it had been years or this was technically his first time, the fact that his body accepted a finger this easily was unbelievable.

Not only that—

The sensation of being stretched open actually felt good.

Worried about hurting myself, I moved slowly and carefully until eventually my palm pressed flush against my perineum.

Suppressing the overwhelming pleasure climbing upward from behind, I slowly pulled my hand back—

Then thrust my finger inside again.

“Hngh— ah!”

A violent wave of pleasure exploded through me so intensely that sparks flashed across my vision.

I repeated the motion over and over, pushing in and pulling back.

Then suddenly another enormous wave crashed through me like a tidal surge—

And my whole body convulsed violently.

“Haah… nngh!”

I’d already climaxed once earlier.

I never imagined I could feel something this intense again so quickly.

Panting desperately, I finally collapsed fully against the bedding, all strength draining from my body.

How long did I stay there trying to catch my breath?

Eventually my head began to clear again.

“…This is insane.”

To think I’d end up masturbating with Geum Seoyul’s body like this—

Not just with my chest, but even using the back too.

There had been moments during the past five years when my body felt restless or heated.

But I’d always endured it.

And yet all it took was one massage with fragrant oil for everything to completely fall apart.

“……”

I absolutely couldn’t touch myself anymore after this.

Even though this was my first time touching myself there, my body had reacted this intensely already.

If I went any further…

I might genuinely become addicted to masturbating.

Carefully, I began pulling my finger out.

The sensation of my inner walls clinging tightly around it was absurd enough already—

But the fact that merely removing it was making my body heat up all over again was even more ridiculous.

Maybe… just a little more?

Without realizing it, I’d already fully removed my finger.

Then lightly, lazily, I traced the folds around my entrance.

The moment I did, another dangerously sweet sensation shot straight to the top of my head.

“Nngh…”

I rubbed the entrance again and again.

Then suddenly I realized—

My hips were swaying shamelessly on their own.

In the end, I pushed my finger inside one more time.

“Hihk!”

Seriously…

What was this feeling?

The sensation of my inner walls clinging around my finger felt far tighter and stickier than before.

But even stronger than that was the pleasure blooming exactly where my finger touched.

It almost felt like every inch inside me was a sensitive spot.

Slowly, I pushed my finger in and out.

At the same time, sweet moans began filling the bathing room.

At this rate, even Yeo-ui waiting outside would definitely hear me.

“Haang!”

But strangely enough—

The thought that someone might hear the sounds I made while masturbating only made my body even more sensitive.

Just imagining it was enough to make my cock ache harder.

Even my nipples scraping against the bedding had become unbearably sensitive.

“Nngh— no…!”

I thrust my finger in and out while desperately rocking my hips.

But after a while, I realized something.

This position made it difficult to reach climax.

Without hesitation, I flipped myself over onto my back.

“……”

The moment I did, my fully erect cock came into view.

So did my hardened nipples, proudly demanding attention.

And maybe because I’d just come out of the hot bath—

My entire body was flushed red.

Using the finger I’d briefly withdrawn while changing positions, I teased the folds again before pushing it back inside.

“Hngh!”

It hadn’t felt bad before.

But lying on my back with my legs spread while accepting my finger inside—

That position was undeniably easier on my body.

Freed from the strain, my movements naturally became faster.

And with every thrust, an even larger tidal wave of pleasure built inside me.

Finally, the sensation crashed over me violently—

And with my finger buried deep inside, I climaxed again.

“Haah… haah…”

Even after coming, my body still remained absurdly sensitive.

Panting harshly, I carefully pulled my finger out before forcing strength back into my trembling waist and sitting up slowly.

“……”

Thanks to the oil, my chest hadn’t become chafed.

But my nipples and chest were flushed such an obvious red that anyone could tell exactly what I’d been doing.

And my nipples were still standing sharply erect.

“Haah…”

Meanwhile, my underwear was completely ruined.

Sighing deeply, I forced strength into my shaky legs and stood up.

Then I removed my underwear, tossed it aside, and used the small bucket beside the tub to rinse myself clean.

After washing away the white streaks clinging around my cock, I carefully stepped back into the bath and sank down into the water again.

“……”

Exhausted and limp, I stared blankly into the air.

Eventually my eyes drifted naturally toward the small window near the top of the room.

And then—

I saw something vanish from the window in an instant.

“…What?”

Had I imagined it because I was exhausted?

But the flash of white I’d seen between the roof tiles and tree branches refused to leave my mind.

Frowning deeply, I wondered whether I’d mistaken it for something else—

Then suddenly, a chill crawled down my spine.

“Yeo-ui!”

“…Yes, Young Master.”

His response came half a beat slower than usual.

Apparently he was still embarrassed from what had happened earlier.

But right now, I didn’t have time to care about that.

I asked immediately:

“Is there anyone outside?”

“Everyone nearby has already been dismissed.”

“……”

“Don’t worry! It’s normal for men to get like that sometimes. I just forgot how sensitive you are and got too focused on the massage, so I overdid it a little.”

“No, not that.”

I honestly hadn’t expected him to interpret my question that way.

Though, in a sense, that was still useful information.

At least it meant this embarrassing situation would remain only between Yeo-ui and me.

Quickly reorganizing my thoughts, I asked again.

“I mean… did anyone happen to stay on the wall outside or something?”

“Huh? On the wall? Of course not! I kept watch the whole time in case someone approached! I checked the rooftops too. I checked everything, but there wasn’t anyone there! Besides, you know this is the Ma Geum Merchant Group’s private annex. Nobody can enter here.”

“…That’s true.”

If Yeo-ui said he checked, then it was trustworthy.

Deciding I must’ve imagined it, I gave him another instruction.

“Bring me a change of clothes. I’m done washing.”

“Please wait a moment! I’ll be right back!”

“Mm.”

The sound of Yeo-ui running off echoed outside.

I listened quietly for a while before pouring more water over my now-cooling body.

‘Yeo-ui’s right.’

No matter how skilled someone was, secretly sneaking into the Ma Geum Merchant Group’s private annex in the middle of the night was impossible.

Convincing myself that what I’d seen was only an illusion, I continued pouring water over myself while waiting for Yeo-ui to return.
