The kill list had suddenly vanished without a trace.

As soon as Amelia noticed something was off, she rushed straight to the Ivory Tower.

That Kill list was the price she paid to fully recover Siwoo’s body.

So if Duchess Keter just decided to wipe it on a whim, Amelia had every reason to figure out what that whim actually was.

But nothing weird showed up.

The Ivory Tower, which no one could enter without Keter’s permission, was closed off to Amelia without exception.

So she went back home, feeling anxious and empty-handed.

She’d meant to sit down and talk things over with Siwoo about all this...

But Siwoo had left behind only a short note on the table, saying he was going to the Countess Gemini’s Mension and he hadn’t returned even after an entire night had passed.

On any other day, she might’ve just pouted and brushed it off.

But the sudden erasure of the list had rattled her, kicked her anxiety into overdrive, and now she couldn’t sit still.

So in the end, she went to see Countess Albireo, hoping she could help track down Siwoo.

“Mr. Siwoo?”

“Yes. He left a note saying he was going to drop by the Gemini mansion. But he hasn’t come back all night.”

Albireo had just finished breakfast and was enjoying her morning tea when she tilted her head in confusion.

If Siwoo was here for the twins, it’d make sense he’d stop by to say hi to Albireo too.

Especially since she’d been cooped up in the lab all night pulling an all-nighter.

“He never showed up yesterday... Maybe he changed plans and went somewhere else?”

Albireo didn’t seem too worried and just brushed it off.

Considering he always had a few women around him, if one were to make a not-so-innocent guess, Siwoo might have come for the twins but ran into Sharon and ended up somewhere totally different.

“Hard to say. Maybe you two just missed each other. Maybe try heading back and see if he’s returned?”

“Okay. Thanks for taking the time anyway.”

If it was anywhere else, fine, but this was Gehenna.

Nothing was likely wrong with Siwoo, but Amelia couldn’t shake this gut feeling that something was off.

Albireo didn’t seem to be hiding anything, so Amelia decided she’d ask Sophia to help track him down.

When it came to finding people, Sophia was near unbeatable.

“Hah...!”

As Amelia turned to go, she suddenly heard this weird little moan from behind from Albireo.

Amelia looked back.

“Was there something else you wanted to say?”

Albireo quickly waved her hands like she was panicking.

That just made Amelia even more suspicious.

Her face was flushed.

Her knees, tucked under her classy dress, were tightly pressed together, and she was kind of hunched forward like she was holding something back.

Her twitchy brows were basically a big neon sign that she was holding something in.

“N-no, I just swallowed wrong... seriously, it’s nothing.”

She hadn’t heard her cough for someone who had something go down the wrong pipe, but since she said so herself, she had no intention of pressing the issue.

“...Alright. I’ll be off.”

2.

Albireo, who had been intently watching Amelia’s retreating figure, immediately hurried into a nearby empty room.

Without exception, those strange moans were always because of Deneb.

Guess Deneb was extra horny this morning.

“Ugh... Deneb... you’re kidding me...”

This ridiculous farce from her shared senses with Deneb had gone way past the point of being just a harmless quirk.

A few weeks back, it was still bearable.

Even if the pleasure bled over, it used to feel kind of dulled, like a cheap knockoff.

But maybe Deneb had been seriously working on her self-exploration?

Or maybe it was just the repeated stimulation strengthening the connection over time?

The pleasure that kept flooding in from Deneb felt almost exactly like what she was feeling herself.

If the earlier waves of pleasure were like a warm shower, now it felt thick, sticky, and hot—like her whole body was being wrapped in molten tar.

Whenever Deneb came, Albireo had to clench her teeth to keep from moaning out loud herself.

“Nnngh... mmgh...”

A bit of luck in the middle of misfortune.

At least Deneb’s little ‘happy time’ didn’t last too long today.

Albireo was starting to wonder—maybe it was time to just come clean.

“If I knew it was gonna turn out like this, I should’ve just said it from the beginning...”

She never thought that trying to avoid an awkward talk would come back around and screw her over like this.

Albireo, who was sighing deeply and going to finish drinking the cold black tea, felt a chill run down her spine.

-press, press

Right between Albireo’s legs.

A place Deneb had never dared to touch before—her untouched spot.

To be more precise, a soft pleasure was starting to stir from her most sensitive, private area.

It was a completely natural hole, whether used for fingering or full-on sex.

But for Albireo, who’d only ever known how good anal could feel, it was a confusing, totally unfamiliar choice.

“W-Wait! D-Deneb? Not there! That’s not the place!”

She felt a thick, heavy pressure slowly pushing inside, creeping up deeper into her belly.

Even though she knew Deneb couldn’t hear her, Albireo squirmed at the strange, alien sensation overtaking her.

Had her little sister’s curiosity finally reached this point?

Sure, acting on curiosity was the mark of a true witch, but Albireo had no intention of sharing the consequences of that curiosity.

She couldn’t hold it in anymore.

Today...she’d tell her.

Today, she was going to tell Deneb everything.

But what followed wasn’t pleasure.

“Ah....!”

Albireo briefly slumped down at the sensation of insertion, which was hard to call perfect pleasure and was closer to pain.

The connection between them had gotten this deep without her even noticing.

“Huh...?”

Then she realized something.

The way this stimulation and pleasure was being obtained was too thick to be a finger.

It felt more like someone was shoving a thick object inside.

“No, no way....”

Albireo’s mind started putting the pieces together.

Siwoo had gone to the Gemini mansion and hadn’t come back all night.

And Deneb? She didn’t show up for breakfast this morning.

Which left only one solid guess.

What if Deneb had spent the night with Siwoo?

And more than that—what if Deneb, still craving the heat from that ‘verification’ with her son-in-law, ended up offering up her other virgin hole too?

Albireo immediately checked Deneb’s location using the brand, and obtained one additional piece of evidence.

That stupidly overpowered pleasure link was still going strong, so Deneb clearly wasn’t in danger.

But Deneb’s actual location wasn’t showing up at all.

There were only two real reasons that could happen.

The first? Deneb was deliberately hiding her location.

She’d done this once before—after a huge fight with Albireo, she ran away and masked her position just like this.

The second possibility

Deneb had crossed over to the modern world.

Still, that seemed pretty unlikely.

Even if she’d done it before, there’s no way she’d sneak off to the human world all by herself, without even telling Albireo, especially with everything going to hell like this.

“.......”

Albireo couldn’t even find the words.

A secret hookup between the little mother-in-law and the son-in-law....

It was so scandalous, she felt nothing but bitter disappointment at Deneb—and outright murderous rage at Siwoo.

Pausing for a moment, then feeling the sensation of deeper penetration again, Albireo could only groan in place, clutching her dizzy head and churning stomach.

Had it been about five minutes since it all began?

“Huu... huu...”

Albireo staggered forward, barely managing to lean on the table and the sofa, like a newborn fawn trying to walk.

And in that moment—she felt a pleasure that shattered everything she thought she knew.

Nothing she’d ever felt came close.

To put it plainly, the pleasure she felt through the link was always a watered-down version of the real thing.

She was feeling it because of Deneb, and yet, for weeks now, she hadn’t been able to come even once.

In short, she’d been stuck in a cruel tease-and-deny loop.

If she tried to get herself off, Deneb would definitely catch on that something was weird—and more than that,

Albireo’s pride wouldn’t let her stoop to masturbating in the first place.

All that backed-up lust had built up inside her like a powder keg—and that huge burst of pleasure set it all off like an explosion.

-Squirt! Squirt! Squirt!

“Haaang!!! Aaang... aaang...!”

Her panties were instantly soaked through.

Her pussy was twitching wildly on its own, squirting out thick, sticky girl cum like it was wringing itself dry.

The flood easily overwhelmed her underwear, ran down her thighs, and soaked her knees—until her shaky legs just gave out beneath her.

“Haa... haa....”

It was Albireo’s first real orgasm—ever. A woman who’d only ever drowned herself in magic research...

It was dazzling, like her vision flashed white, and intense enough to blank her mind.

But even so, Albireo came back to her senses fast.

“Deneb... what the hell are you doing...?”

She muttered under her breath, voice trembling with frustration, cursing out her little sister who couldn’t even hear her.

She never thought Deneb could be this careless... actually giving her body to Siwoo?

How the hell was she going to face their sweethearts after doing something so outrageous?

No.

This is all Shin Siwoo’s goddamn fault.

“Shin Siwoo... you goddamn bastard of a son-in-law. Not only do you fail to keep her in check—you go along with it like it’s nothing? Ugh...”

As if screwing every woman in sight wasn’t enough, now he’s gone and opened up both ends of his little mother-in-law too.

Deneb may be old, but when it came to men and sex, she wasn’t any more experienced than the twins.

And to mess around with someone so innocent? That’s a goddamn crime.

“Just you wait, asshole...”

Albireo swore that when they came back, she was going to chew Siwoo out so bad he’d be bawling his eyes out like a baby.
