Scáthach and Tamamo.
The nightly tug-of-war between the mistress of the [Abyssal Realm] and the dazzling great yokai was nothing less than a catastrophe.
By day, Kay's bones were pounded to dust by spear thrusts; by night, he was wrung dry by the two women's inexhaustible stamina and possessive demands.
No matter how virile the mighty Kay claimed to be, in their presence he felt as though his very marrow had seeped out in weariness.
"…Not today. If I get swept away again tonight, my waist will turn to powder."
Exhausted, Kay pleaded for mercy and fled to his personal chambers tucked in the corner of the castle.
He locked the door securely, then collapsed onto the bed. No sooner had he closed his eyes than a crushing fatigue overtook him, and his consciousness plummeted into the abyss.
Warm sunlight. A gentle breeze tickling his cheek.
When he opened his eyes, Kay found himself not beneath the ashen sky of the demonic realm, but standing on the familiar, beloved fields of Britain.
"…A dream, then."
He guessed it was a dream, but the vividness of the scene lulled him into a false sense of security.
That was when he heard a clear, familiar voice behind him.
"O brother."
Kay spun around, eyes wide.
Before him stood a silver-tinged blonde girl in a diaphanous white dress—no training gear, no boy's clothing. It was Artoria.
"Ah, Artoria?"
"I've missed you, brother. Every night I long for the smell of your cooking and the warmth of your presence."
This was not the stalwart King of Knights he knew.
Her cheeks were flushed like peaches, her emerald eyes dazed. She glided forward and threw her arms around Kay's torso.
"Hey, wait! Artoria, you're acting weird—never mind, it's a dream!"
Kay jerked back, attempting to push her away. No matter how much it was a dream, he couldn't tolerate this sticky intimacy with his sister.
But he found he had no strength.
As if poisoned, as if wrapped in unseen serpentine coils, not a finger would obey his command.
His head spun, and a strangely mature, potent floral scent—far beyond her usual fragrance—numbed his senses.
"This can't be…."
Kay parted his lips in protest, but Artoria rose onto her toes and breathed hotly against the nape of his neck.
"It's alright. No one can disturb us here… in this sweet sanctuary."
Her soft lips trailed up his collarbone, and through the thin dress he pressed against the small curves of her body.
The visual shock, the paralyzed reason, the hypersensitive touch—all at once overwhelmed him.
Soon, she began to undress slowly before him. In an instant, the dreamscape shifted into the familiar house of his childhood.
"You're hot, brother."
Artoria's tongue flicked across his face. Then she impaled herself on him.
He was being ravished by her, yet felt no revulsion. His haze-filled mind swam in ecstasy, and only desire writhed within him.
"Give me more… your body…"
At last, the final thread of Kay's sanity snapped.
Driven purely by instinct, he drew the illusion close and returned her ardor with fervent embrace.
On the dream-bed, Kay began a scorching, intense liaison with the sweet phantom that had paralyzed his reason.
"Harder… even harder!"
Once, twice… countless climaxes spilled forth, mana flooding from him in waves. It was overwhelming pleasure, as if his soul itself was being sucked away.
And at the final white-flashing moment...
"…Thank you for the meal, Master."
The golden-haired girl in his arms shattered like glass, and in her place a cascade of long, sleek violet hair fell.
An eye-covering blindfold. A cool, seductive smile.
It was not Artoria.
The succubus who had manipulated his dream and numbed his senses.
It was Medusa.
"Gah!!"
Kay's eyes snapped open.
Britain's fields were gone. He lay again in the darkened bedchamber of the demonic realm.
Yet even after waking, the heavy weight pressing on his body and the raw pleasure coiling around his loins did not fade. If anything, reality made it all the more intense against his skin.
"You're awake. You were so passionate in your dream I almost lost my reason too. Even if it was a dream, I matched you in reality—if I'd been a goddess I couldn't have held back."
From the darkness...
Medusa straddled Kay, her black tights half-pulled down, every inch of her pressed flush against him.
She had engulfed his lower half and now writhed her hips in sinuous, sensual motions, slamming down like a serpent.
squelch… creak♡
"You, ugh… Me-Medusa… what are you doing…!"
"As you see. I needed mana, and you're a superb supply. I couldn't bear to let Tamamo and Scáthach monopolize you—your scent is far too potent."
Medusa flicked out her long red tongue and licked the sweat-beaded skin of his chest.
Her vampiric charm had Kay's body in complete paralysis.
"What a marvelous body. I heard you were ordinary, but the size of your vessel… and this formidable weapon you wield—even the heroes of the new age would envy it."
She whispered in awe, coiling around his torso like a serpent.
The chill of her flesh blended with his heat, setting him ablaze. Despite dozens of climaxes in the dream, the onslaught of real physical pleasure swelled him once more.
"Ugh… release me, my body…."
"Will you continue to yield only to me? You hate losing control, don't you?"
Medusa curled her lips and eased the spell's grip on him—just enough to give him hope.
At that moment, as the paralysis began to lift, Kay's battle-honed instincts detonated like a beast.
Despite his haze, he seized Medusa's slender waist with both arms and in one motion flipped their positions.
"Ah!"
Medusa collapsed onto the bed with a surprised gasp.
Kay panted like a wild animal, then began thrusting violently with merciless speed.
"You lit the fire first…"
"Haah! Ma-Master… wait, so deep… ugh! Yes♡!"
Reflex overrode reason.
Medusa had thought she'd drained him in the dream, but his endurance and stamina far exceeded her expectations.
"Oh… magnificent, Master. Harder… harder♡. Carve your beast-like mana… deep into me…♡!"
"Gods, are all women in myth this obscene!? Because of you, I can't keep my head straight!"
"I'm sorry♡. I'll atone with my body—rougher, more violent! Devour this body that even sea gods coveted♡!"
Medusa cried out in ecstatic bliss, legs tightening around Kay's waist.
On the deep, dark night of the demonic realm, Kay's bedchamber had become a lust-soaked mire where serpent and predator entwined.
"…Ah, I'm gonna die."
The next morning.
Kay sat up and pressed his palm to his forehead. His waist felt numb and his body bone-dry.
He looked down into his arms and saw Medusa sleeping soundly on the desk, her blindfold removed and set aside.
The usual cold reserve was gone, replaced by the voluptuous form of a woman bathed in a red glow.
Hearing him stir, Medusa slowly opened her eyes.
"…You're awake, Master."
She stretched and nuzzled his chest. Thanks to last night's fierce coupling, her skin glistened and her mana was at its peak.
"Thank you for the meal. Truly an exquisite feast—quite enough to burst my belly. I look forward to… more occasions like this."
She whispered with that signature seductive smile.
Kay sighed in exasperation.
"You really… manipulate dreams to ensnare people? How long have you been after me? Did you ever even see me as a man?"
At Kay's deadpan question, Medusa tugged the covers up to her chest and answered candidly.
"Servants can't get pregnant and lack human physiology. So it began purely as mana procurement and sexual release. I too, as a monster, have a ravenous appetite."
She reached out and stroked Kay's cheek.
"But… it's true I admire your unwavering spirit and the kindness with which you fight tooth and nail for your sisters. I don't lack the pride to share flesh only with someone I like."
Medusa's frank confession made Kay's face heat without his realizing it.
"…You sure talk a good game."
Just as the two were savoring the lingering tickle of morning beneath the covers, a sudden crash came from the door.
Bang!
"Hey! You pathetic cook! The sun's high and you're supposed to be making breakfast—what the hell are you hiding from…!!"
The chamber door flew open, kicked in by an unwelcome intruder.
It was Jeanne d'Arc Alter.
She had come looking for breakfast but froze at the raw scene before her.
Clothes strewn about like a shed snake's skin.
The heavy scent of night-blooming flowers mixed with a briny musk.
And Kay and Medusa, bare-chested under a single sheet.
"Uh… um, Jeanne. This is, I mean…"
Before Kay could form an excuse, Jeanne d'Arc Alter's pale face turned beet-red.
"Y-you… you two… what insane deed were you committing in broad daylight!? You… you horny beasts!!"
Jeanne d'Arc Alter half-hid behind her banner as she screamed.
Yet through her fingers she couldn't help but stare at Kay's taut abs and the illicit atmosphere of the bed.
For the avenger whose mind knew only vengeance and wrath, it was the first time she had tasted such potent cognition of sex.
"Oh my? What is all this commotion? Whatever is happening to my husband…"
And adding insult to injury, Tamamo and Scáthach thundered down the corridor at the sound of Jeanne's screams.
Tamamo's eyes flared blue when she realized the scene, and Scáthach already had [Gáe Bolg] in hand.
"Hee, you really tried to snag a free catch?"
"You ate every scrap that was meant for me. Looks like tonight's barbecue will be snake skewers."
"…I'm full now, so I'll take my leave. Master, good fortune to you."
With a sultry smile, Medusa vaulted through the window and fled.
Only Kay remained on the bed, clad in nothing and sweating cold beads.
"Um, you guys? Last night I got drained of every drop—so please, no more violence… uaaaah!!"
In Medusa's absence, Tamamo and Scáthach descended upon the slowly recovering Kay.
Out of stamina? With Tamamo's ninjutsu and Scáthach's primal runes, only his spirit remained at stake.
Jeanne d'Arc Alter muttered as she bolted out, feeling an unfamiliar warmth flicker within her.
