The Beast's Demonic Claw Sinks into the Radir Household!
"......"
In Cecilia's room, where a chill hung in the air, the servants attending her watched her mood with tense expressions as she bit her nails.
"......Mother still isn't back?"
"...No, miss..."
"I see... still not..."
The tense atmosphere stemmed from Cecilia, but unlike usual, there was a good reason for her foul mood.
The lady of the Lord's Castle had vanished on New Year's Day without explanation. Celestia.
The servants here didn't know the full details, but they could tell Cecilia's displeasure was tied to that.
'It's past lunchtime already... and still...!'
She'd heard something about a party, but even so, this was too late. What kind of party lasted three days with no word?
If it were a noble's gathering in another city, she might understand, but Celestia was at a monster's party in Radia.
Even if it was called a Divine Beast, for a noblewoman to attend a non-noble monster's party and stay this long was downright bizarre.
But that was just mildly suspicious at worst. What truly worried Cecilia was...
'No way... really... Mother...'
An affair between that monster and her mother...
Affairs were fairly common gossip among noblewomen, really. In noble society, where political marriages abounded for business or title preservation, half of all noble couples lacked love. Tales of some wife cheating were dime-a-dozen chatter.
Until two or three years ago, during sex ed, she hadn't grasped condoms' purpose. She'd learned at last year's noble ladies' tea that noble wives quietly drove demand for them.
But... she'd thought her parents were above such things.
And Celestia had drilled into her an excessive hatred of monsters. For her to cheat with one—even a Divine Beast, a half-formed freak—defied belief.
"...But those traces in the bedroom the other day..."
She lacked experience, but no human could leave marks like that.
Her parents' bedroom bore such traces. Mother vanished, ditching family time. Father acted suspiciously, hiding something.
It all pointed to one conclusion for Cecilia.
'...Mother's still young, so I get it somewhat. Rumors said they hadn't shared a bed lately. But... even so...'
Even so, she couldn't accept her mother cheating with that monster.
A half-human abomination. Plenty of nobles... or even commoner men, but that monster?
'Sure, it has that impressive... no, wait! Muscles that look strong, but it's a monster...'
True, it had something special no other man possessed. Muscles far superior to any human she'd sparred with.
She'd felt its overwhelming strength and stamina punching its abs—likely from those muscles. And that heavy heft when she'd kicked with full force...
...If the egg-like size she'd sensed extended to its cock...
'...No, no. Even then, not with Mother...'
"Miss! Lady Celestia has returned!"
"Mother!?"
"Y-yes...! B-but... ah, miss!"
The maid announcing Celestia's return seemed to want to say more, but Cecilia bolted from the room, ignoring her.
She had a ton to ask now that her waited-for mother was back. Did she know about Father's state? What were those bedroom traces? Why attend that monster's birthday party? And... what was her relation to that monster, Sema?
Pondering these, Cecilia raced toward the entrance from the administrative wing to the lord's family quarters.
Then, spotting blue hair in the distance—presumably Celestia.
"M-Mother! ...Huh?"
Cecilia froze at the sight of two figures.
Of all times, Mother appearing with that monster.
But more shocking still...
"Ahh♡ Sema, you...♡ Here of all places...♡"
"We're gonna be apart a while, right? Gotta enjoy Seres's body while I can."
"Heehee♡ Guess I can't argue. Enjoy me all you want♡ Sema♡"
Celestia, clinging to the monster, her voice laced with coquetry. Cecilia couldn't believe this was her mother.
Her hair down was one thing, but that outfit felt utterly alien on Celestia.
"M-Mother...?"
Celestia's wardrobe split two ways: flowing noblewife dresses or occasional mage robes. Minor daily variations aside.
But now? Neither.
What the hell was that getup?
"Oh my. Cecilia. Come to greet me?"
"M-Mother...? What is that outfit...?"
"...Ah, this? Heehee♡ A gift from Sema♡"
A gift? That whore getup was a gift?
A flashy long coat draped over it, sure, but underneath? Absurd.
A skin-tight dress, ridiculously short. What even was it?
Straps around the neck plunged to barely cover her nipples with scraps of fabric—topless, basically. Not gloves on her hands, but arm warmers in matching color up past her elbows peeked from the loose coat.
Naval cutout on the belly, sides slashed to the hips exposing panty strings. Skirt so short panties flashed constantly, mound outlined brazenly each time.
Fishnet stockings evoking shame below, sky-high heels that looked torture to walk in. Topped by a choker like a dog's collar with odd ornamentation.
The fur coat screamed luxury, but it made Celestia look less noblewife, more streetwalker.
"I'm an ice mage, right? Told him I'm resistant to cold, so Sema picked this out. Pretty cool, huh? Heehee..."
She brushed back her side hair with a delighted smile. Cecilia spotted deep blue nail polish.
And her makeup—sultry, seductive, unlike her usual restraint. Flashy, high-class, yet utterly tacky, devoid of noble grace.
"Puhuhu... Seres is so damn hot, huh? Dressed to my tastes like this, my dick won't quit throbbing down there. You love it but whine it's not enough."
"Oh my♡ Can't hold back? Then in my room...♡ Poke poke♡ What do you say?"
"Kukuku. Wanna play a bit, then?"
"Ahh♡ Please...♡ I'll prepare fine tea for you, Sema♡"
Cecilia, seeing her mother nuzzle the monster like a bitch in heat, had to face facts.
Her mother had cucked her lord father... for this monster.
That realization hit; she screamed at the monster before her.
"Y-You...! Hey, you fucking psycho monster bastard!"
Indescribable rage surged through her.
"You goddamn lunatic! You lost your mind!? Know who you just fucked with!?"
The monster she'd warmed to felt utterly loathsome now.
"You're a total psycho! Fuck, no one else to target, so the lord's wife!? The very woman who let you settle in Radia!? You're fucking insane!"
She'd seen it as her toy. Sema. Thrilled at snagging a rare Divine Beast, never dreaming it'd touch her parents.
Recent flutters toward it felt like betrayal; inexpressible fury shook her body.
"You fuck, you know what happens touching nobles!? Divine Beast my ass—you're done! I'll chop your head off and hang it at Radia's gate...!"
-Slap!!!
Mid-rant, a stinging slap whipped her head around, silencing her.
The monster hadn't moved.
So who...?
Dazed by the cheek pain, Cecilia soon spotted the culprit.
Her own mother, Celestia, glaring with unprecedented fury.
"What rude mouth to Sema! Cecilia!"
"M-Mother...?"
Absurd. Mother shouldn't be mad here. She shared blame too.
"Spoiled you rotten, now you forget your place and run wild!"
How was her mother so brazen amid family ruin?
"Sema gracing Radia is honor enough—dare spew such filth!"
Why defend this monster so fiercely?
"No title yourself, just riding parents' flimsy noble status to strut!?"
Why cozy up to a monster she'd despised?
"Delusions have limits! Think your mom did something dirty with Sema!?"
Why scold her instead?
"Even your father Albert approved! Who are you to meddle!?"
"W-What...? Father... did...?"
Impossible. Father approved this?
Wait, he'd seemed oddly fine...
N-No way...
"Haa... Sorry, Sema♡ My poor education left my daughter so ill-mannered..."
"Kukuku. It's fine, Seres. From now on, focus on training our lady, yeah?"
"Ahh♡ So merciful, Sema♡"
Her mother's look—unbelievable. Like a bitch in heat fawning over a stud...
"...Won't do. I'll ask Sema to switch your training to daily etiquette lessons."
"W-What...? Daily!?"
"Only way to fix that attitude. No seeing Leo for a while either!"
Celestia's absurd decree, near corporal punishment.
The monster's arm around furious Celestia's shoulder flipped her back to fawning bitch, nuzzling his side.
"Kukuku. Seres, daily's too much."
"Oh♡ Then whenever suits you, Sema? I'll keep Cecilia waiting in the castle♡"
"W-Wait! Mother...!"
"It's decided. No nonsense, Cecilia. I need to talk with Sema—back to your room. Now, Sema♡ To my room...♡"
"Puhuhu... Yeah. See ya, Lady Cecilia."
Something was wrong, but Celestia's blissful face silenced her.
Leaving stunned Cecilia, monster and mother strolled the hall.
Sensing lingering beastly musk, Cecilia could only stare at their backs.
