After finishing breakfast, Hyoudou Issei moved on to training together with the other Gremory household members.
Just like yesterday, Issei was doing close-quarters combat training with his comrade, Kiba Yuuto. Since Issei had only achieved his reincarnation from human to devil just about a month ago, in April, he still lacked combat experience. It was only natural — he had lived a peaceful, ordinary life in Japan, a peaceful country, so he was nowhere near the level of Yuuto, who had been training in combat from a young age.
"Right there!"
Issei swung his wooden sword downward toward Yuuto, who stood in front of him with his own wooden sword at the ready. It was, for Issei, a full-power, fastest strike he could muster — but to Yuuto, it might have looked slow enough to seem stationary. In the very next instant, the figure he had locked onto disappeared from before his eyes, and from his side came a voice filled with a sharp edge.
"You're full of openings."
"Uwah!"
A strong impact ran through the base of Issei's wooden sword, forcing him to let go of the grip.
Immediately after, the tip of Yuuto's wooden sword drew near to Issei's neck. Turning to the side, Issei saw Yuuto standing there with the weapon pointed at him.
"I give up…"
"That makes three wins and zero losses."
When Issei raised both hands, Yuuto said that and gave him a light smile. Issei had already begun sweating, yet Yuuto looked perfectly composed. For him, this probably didn't even count as a warm-up. Standing with a backdrop of blue sky and grand nature, the blond and handsome young man's refreshing aura remained entirely undiminished.
Of course it would.
Their training hadn't even lasted an hour yet.
And yet — Issei had already been defeated three times.
Every match followed the same pattern: he couldn't even land his simplest flurry attacks, got impatient, swung too wildly, and lost to the counterattack Yuuto delivered in the opening he created.
He understood he needed to think more before acting.
But even if he could think, he couldn't execute properly.
Once the fight began, his field of vision narrowed rapidly, and he would just throw out attacks at random.
This won't do.
He had to move more calmly.
Training time was not unlimited.
Including today, the Rating Game would take place in nine days. Issei, who had been a human until recently, didn't know the details, but the Rating Game was apparently a popular form of entertainment in the underworld. Two factions split up and battle — whichever side fulfills the conditions becomes the victor.
And depending on the result of that game, the fate of Issei's master, Rias Gremory, would be decided. If Rias' Gremory faction were to lose against their opponent, the faction led by a man named Riser Phenex, then Rias would become engaged to Riser. She would marry someone she did not love, have her purity taken, and eventually bear his children.
Issei didn't know Riser well, but the impression he got when they met in the clubroom was unpleasant. He seemed to have enough manners to return Rias and Asia Argento's "greeting," but his attitude was arrogant from start to finish.
There is no way the President would be happy marrying that guy.
And more simply — the idea of someone taking Rias away from him made him feel terrible.
That's why Issei thought only of defeating Riser.
He absolutely must not lose.
He had to become stronger — even a little — to ensure victory.
Issei once more took his wooden sword in hand, took distance, and faced Yuuto again.
"Kiba, one more time."
"Of course. Anytime, Issei-kun."
The reason he couldn't act well, the reason his vision narrowed — it was because of his lack of experience. He just needed more matches, more thought, and slowly to grasp the feeling. Issei believed that was the fastest way.
President… I'll become stronger.
I'll become strong enough to protect you from that man.
Gripping his wooden sword tightly, pouring his feelings into it, Issei charged at Yuuto with a spirited shout.
While Issei and Yuuto were devoted to their training,
Rias was indulging in masturbation in the villa's living room.
"Nn… ah…"
Having undressed and now completely naked, Rias sat on the sofa with her legs spread in an obscene letter-M shape, using her fingers to tease the center of her crotch.
Each time her fingers pierced her vaginal entrance with wet kuchu, kuchu noises, she raised her voice and shivered.
Among all the times she had masturbated before, this moment felt the best.
The pleasure was so overwhelming she could boldly declare it.
Another sweet moan spilled from her lips.
"Ah… nn… nnn…"
Next to Rias, Himejima Akeno — in the exact same state — was repeatedly masturbating as well.
Even to a fellow woman, her sultry voice was filthy and obscene, and the wet sounds produced by her intensely active fingers only heightened the arousal.
And above all else, the sight unfolding before Rias' eyes accelerated her masturbation further.
"Budyuu, jyubo, gupu, gupoo, jyuru, guchu—"
It was an abnormal sight —
a thick, erect cock jutting from the crotch of a young woman, being sucked by another girl.
The owner of that cock was Toujou Koneko, a member of Rias' household.
She was usually quiet and expressionless,
but now she wore a wicked grin the likes of which Rias had never seen.
Her beautiful, petite adult body trembled as she held the girl's head with both hands.
"You're doing well, Asia-senpai…"
The girl addressed — Asia — was crouched on the floor in a wide-legged squat,
continually providing oral service to the cock.
Her long blonde hair swayed, her still-developing adult breasts bounced, and with a face drowning in lust she sucked the member like a whore.
"Budyuu, jyuppo, gupoo, jyubu, guchu, jyuru—"
The intense sounds echoed through the room.
Though overpowered by those noises, Rias and Akeno's masturbation was also loud.
With one hand abusing the clitoris and the other delving deep inside,
the lewd sound of slick fluids echoed as they drenched the sofa and floor.
Why were they all naked and masturbating during training?
Why did a cock exist between Koneko's legs?
Why was Asia sucking Koneko's cock?
Several questions floated into Rias' mind mid-masturbation —
but they vanished instantly.
Instead, a different recognition filled her brain,
and Rias accepted that new belief as truth,
moving her fingers as if compelled by a new instinct.
This was training.
To master a secret technique that they would unleash
if they seemed about to lose to Riser in the Rating Game nine days later.
In front of Riser, the girls would masturbate while one of them sucked his cock.
That would surely rattle Riser and make him freeze.
In that moment, Issei and Yuuto would launch their attack — that was the ultimate technique.
It was perfect.
She was proud to have come up with such a tactic.
If they perfected this technique, they would not lose to Riser.
"Ahh… nn… ngh…"
"Kuh… ah… ahh… aah…!"
"Budyuu, jyururu, jyuzozoo, jyubu, gupu, jyubo—"
Thus, Rias — they all — continued their training.
Determining which girl would take which role,
what formation to create…
through repeated trial and error.
Rias stood up from the sofa, then crouched beside Koneko — taken as the stand-in for Riser — and spread her legs, masturbating in a squat like Asia.
Seeing this, Akeno also positioned herself beside Koneko in the same posture, thrusting her fingers into her vagina.
Alongside Asia, who was sucking Koneko's cock,
the three formed a surrounding formation around Koneko.
No matter which way "Riser" looked,
only lust-filled females would fill his vision.
Riser would be left frozen in place,
forced to endure Issei and Yuuto's relentless attacks.
With this—
it would work.
Riser Phenex, third son of the Phenex house —
with an immortal phoenix body.
Even if his body was immortal, his heart was not.
With this Gremory-style Lustful Bitch Encirclement Formation,
they would halt his movements,
and as Issei and Yuuto continued their attacks,
his heart would wear down and he would be forced to his knees.
As proof — the face of the mock-Riser Koneko distorted.
"Amazing strategy… if it's like this… I would lose…"
Her tone was oddly stiff — probably due to Koneko's lack of acting skill.
Seeing her wooden acting, Rias chuckled softly,
then let herself be carried by the arousal rising within.
It was rough masturbation unlike any she'd done before —
enough to form a puddle beneath her.
The scent of female lust filled the air.
And yet, just a whiff of the thick masculine scent was unmistakable.
The scent wafting from Koneko's cock delighted every inch of Rias' body and sought to enthrall her heart.
If she dropped her guard, she felt she might fall to her knees naked and swear eternal loyalty,
but she resisted somehow — and climaxed.
Pshhh, pshaa — she squirted.
At the same time, it seemed Akeno had also squirted.
Their twin squirting sprayed over Koneko's legs,
and matching that timing, Asia sucked the cock even harder.
In that instant — Koneko's face melted in ecstasy,
and she began to ejaculate.
"Byurururu, byuru, byuuu, dobuuu, dopu, dobyu, dok!"
"Mnnf! Ahh— nggh!"
Asia swallowed the cock to the back of her throat,
receiving semen directly into her mouth.
She groaned, desperately gulping,
but the amount was far too much.
Semen backwashed out of the corners of her mouth,
even from her nostrils.
Unable to endure anymore, Asia pulled her mouth away,
and a flood of semen splattered across her entire body.
Byuru, dobyuu, byuu, dopu, dopu, byuru—
"Haa… haa… haa…"
Asia's adult body became covered in white fluid as she panted like a dog.
Her face looked truly delighted — befitting a bitch who fawns over men.
Surely this would bait Riser into letting down his guard.
Satisfied with her subordinate's fine performance,
Rias kept releasing squirting orgasms like ejaculation.
It was complete.
All that was left was to practice until they could do it in the real match.
Just you wait, Riser.
With this— we will not lose to you.
"Idiot…"
Koneko said something with a laugh-like breath,
but Rias was too lost in self-satisfaction to hear it.
Meanwhile, Issei and Yuuto continued their sparring under the bright sky.
Issei's breath soon turned rough, shoulders rising and falling with each gasp.
His arms trembled slightly from gripping the wooden sword too tightly.
In contrast, Yuuto's breathing remained calm — like a gentle breeze.
"You're improving the speed of your approach.
But you still overcommit on your strike," Yuuto advised,
taking a small step back to reset the distance.
"I know… but my body just… doesn't move the way I want…"
Issei wiped his forehead with his sleeve, sweat smearing across his brow.
"It's only been a month since you awakened as a devil.
You're progressing frighteningly fast by ordinary standards," Yuuto said kindly.
But that kindness only tightened the knot inside Issei.
A brief silence.
Then the worry weighing on him spilled out:
"Hey, Kiba…
Do you think we can really win… against Riser?"
Yuuto blinked, surprised by the sudden doubt.
"…We'll win," he answered without hesitation.
"But of course— we need everyone's strength.
And Issei-kun… that includes you."
The sincerity in his voice struck straight into Issei's chest.
Issei clenched his teeth and tightened his grip on the wooden sword again.
"I'll… I'll do it.
I'll protect Buchou.
I promise."
Yuuto smiled — soft, but strong.
"That's the spirit.
Let's keep going."
Just then—
zubababababababaaaaan!!!
A thunderous explosion echoed from the direction of the villa.
The ground shook slightly beneath their feet.
Issei and Yuuto exchanged shocked looks.
"What the…!?"
"That came from the living room…"
Yuuto's expression turned serious.
He immediately began running toward the villa.
Issei followed right after.
"Wait! Don't tell me someone attacked!?"
But as they approached—
they heard no screams, no shouts, no signs of combat.
Only—
Kuchu… jyupo… bizu-bizu…!
Lewd wet sounds and moans that made Issei's brain nearly short-circuit.
"What… is that…?"
"It can't be…" Yuuto muttered, his eyes wide.
Issei, bracing himself, swung open the living room door—
—
Inside—
Rias, Akeno, Koneko, and Asia—
were still completely naked, continuing their "secret technique training,"
semen and love juices staining the floor like a battlefield of lust.
Asia knelt obediently, licking up the semen spilled earlier.
Koneko leaned back against the sofa, lazily stroking her still-erect cock.
Akeno's fingers toyed with her twitching clitoris as she panted out sweet breaths.
Rias squatted boldly, shaking her hips while masturbating fiercely, droplets spraying the floor.
Issei froze.
His eyes, his brain, his soul— all stopped.
"What—
What are you doing!!??"
He shouted louder than he had during any battle.
Rias turned toward him with a bright, proud expression.
"Training, of course."
Akeno flashed a sensual smile.
"We're practicing the ultimate strategy ♥"
Koneko pumped her fist weakly.
"It's perfect…"
Asia, her face dripping semen, looked up with a dazed, blissful smile.
"If we do this… we definitely win…"
Issei felt his vision blur.
Every cell in his body screamed WHAT IS GOING ON!?
His mouth opened and closed, no words forming.
Yuuto, beside him—
had collapsed to his knees.
His beautiful expression shattered.
He stared blankly at the debauched scene before him, lips trembling as if his spirit had left his body.
"…I have seen hell," he whispered.
With a heroic resolve, Rias pointed directly at Issei.
"Issei!
When the time comes— you and Kiba will attack!
While we charm Riser with this!!"
Issei's voice finally erupted:
"That makes no sense at all!!!"
But Rias, blazing with confidence, declared:
"This is… the Gremory household's new secret technique—
Lustful Bitch Encirclement Formation!!!"
Issei clutched his head—
and let out the loudest scream of his life:
"WE'RE DOOMED!!!"
"Calm down, Issei!" Rias insisted, placing both hands on her hips with her bare breasts boldly on display.
Her nipples were still hardened, glistening with leftover fluids, which only made it harder for Issei to calm down.
"How can I calm down!?" Issei shouted back, face bright red.
"This plan is completely insane! There's no way something like this would work against a guy like Riser!"
Rias puffed out her cheeks slightly, as if personally offended.
"Riser is a depraved man surrounded by his own group of 'servants.'
He won't be able to resist something like this."
"That's the problem!!"
Issei yelled in a voice that nearly cracked.
"That's EXACTLY why he wouldn't freeze! He'll ENJOY IT!"
Rias blinked.
Koneko paused her stroking.
Asia tilted her head with semen still dripping from her cheek.
Akeno giggled softly.
"…He has a point," Akeno murmured.
"Indeed," Yuuto said, his eyes dark and empty.
"I know the feeling of facing a naked woman. One does not freeze… One… attacks."
Rias looked momentarily troubled.
Her brows furrowed.
"…I see."
She crossed her arms— which only emphasized her large, bouncing chest.
"In that case… we need to think of a new approach."
Issei exhaled in relief—
but only for a moment.
Rias' face lit up again, as if struck by inspiration.
"I know!
We will seduce him… THEN attack while he is in the middle of intercourse!"
"NOOOOOOO!!!"
Issei screamed so loud that birds flew from the trees outside.
"President! Listen to me carefully!!
We need a NORMAL strategy!
You can't just rely on sex attacks!!!"
"But Issei…" Rias said with absolute seriousness,
"Sex attacks are speed attacks."
"That's the worst line I've ever heard!!"
But Rias wouldn't give up.
"Fine, fine… we'll train properly too.
Magic, formation tactics, coordination drills…"
Issei breathed out in relief again.
"And we will include daily sex technique training in the schedule!"
"NO ADULT ENTERTAINMENT TRAINING EITHER!!!"
Rias turned away as if sulking.
"Hmph… I only wanted to do my best for everyone…"
Issei's heart lurched.
He couldn't stand seeing that expression on her face.
He swallowed.
"…President.
I… I know you want to protect us.
And I get that you're desperate for a way to win."
Rias slowly turned back toward him.
Her expression softened.
"…Issei."
A moment of quiet understanding passed between them.
Then—
Akeno leaned in from the side, smiling with devilish amusement.
"My, my… Rias.
It seems Issei-kun prefers 'hands-on' motivation~ ♥"
"STOP INTERRUPTING WITH YOUR EROTIC COMMENTARY!!!"
Akeno giggled.
Rias smiled gently.
The tension gradually melted from the atmosphere.
Rias placed one hand on her chest and spoke calmly:
"…I trust you all.
Let's win together.
Properly, this time."
This time… she said.
Asia nodded, wiping semen from her lips.
"Koneko, thank you for helping with the strategy…"
Rias said kindly.
Koneko, still naked with the cock between her legs, muttered:
"…Never again."
