High School DxD: I'll Summon My Harem

The day of Yuiga Taro's move had finally arrived.

Summoned by his relatives, he was set to leave the countryside where he had lived and relocate to a new city, Kuoh Town.

Compared to his rural hometown, this place was a bustling metropolis. The towering buildings, flashing neon signs, and endless streams of people left Taro in awe as he took in the urban scenery for the first time.

His relatives' home was a modest apartment, roughly a 2LDK in size—more than enough space for a single person. After setting down his belongings and settling in, he was given a tour of the place.

The first thing he saw upon entering the living room was the kitchen, complete with a refrigerator and a large TV. Adjacent to it was the bathroom, spacious with a separate toilet.

Next, he was shown the bedroom, furnished with a bed and a closet beside it. The rest of the apartment was well-equipped with various other furniture.

Once the tour was over, dinner time arrived.

"Sigh… I'm exhausted. Seriously, they were the ones who called me here, and now they're both flying off overseas right away…?"

Left alone, Taro let out a tired sigh.

His uncle and aunt—the relatives who had taken him in—had both left for an overseas business trip, leaving him to house-sit.

Though he wanted to complain, he wasn't in a position to do so. As a small gesture of gratitude, he decided to take care of the household chores—cleaning, laundry, and meal prep.

But even after finishing his tasks, the day was far from over. With nothing else to do, boredom crept in.

That was when his eyes landed on a peculiar book resting on the table—"Demon Summoning Tome."

The cover bore the word "Devil" in bold letters.

"Demon Summoning Tome? What the hell is this?"

Curious, Taro picked it up and began flipping through the pages. At first glance, it seemed to contain various magical rituals, but upon closer inspection, most of the pages were blank—no incantations, no magic circles, nothing.

"What kind of joke is this?"

Just as he was about to dismiss it, one particular section caught his eye—a detailed guide on summoning a demon.

"...Why is something like this here?"

The contents were shocking. Every step, every material needed—it was all meticulously written out.

"No way… Is this for real?"

Skeptical but intrigued, Taro decided to give it a try. Surprisingly, all the required materials were already in the house. Following the instructions precisely, he performed the ritual.

And—it worked.

The magic circle glowed brightly, and an eerie presence filled the air.

"This is…!"

From within the radiant sigil, a single figure emerged—a young woman.

She was unmistakably foreign, with silver hair tied into a braid and dressed in a sleek black maid outfit. A pristine white apron adorned her chest, and her skirt was modestly long, though the deep cleavage of her dress was impossible to ignore, not that she seemed to care.

After briefly examining herself, her sharp gaze turned toward the magic circle, and then to…

Her summoner… Yuiga Taro.

She appeared momentarily stunned, struggling to process the reality of her summoning. Swallowing softly, she forced out a question.

"…Are you the one who summoned me?"

Her voice was smooth, yet laced with quiet disbelief. Taro nodded honestly.

She studied him intently before exhaling, as if resigning herself to the situation.

"…My name is Grayfia Lucifuge," she said, her tone formal yet oddly intimate. "Might I know yours?"

'Grayfia Lucifuge.'

The name hit Taro like a thunderbolt. His shocked reaction made her brow furrow slightly, prompting him to stammer out his reply.

"I-I'm Yuiga Taro."

"Then I shall address you as Taro-sama," Grayfia murmured. "And to confirm… You are the one who summoned me, correct?"

Her crimson eyes bore into him, demanding clarity.

"Yeah, but… I wasn't even sure the spell would work," Taro admitted, scratching his head before gesturing to the glowing magic circle at their feet.

Grayfia's eyes widened—a rare crack in her composure.

"…This is the circle you used?"

"Huh?"

Taro blinked, confused by her reaction. But Grayfia swiftly masked her shock, though not before he caught the tremor in her fingers.

"…Very well. As per the contract's terms, I shall fulfill your desire, Taro-sama."

"My desire? Wait, I didn't—"

"The duties of a demon summoned through this particular ritual are already predetermined," she interrupted, her voice lowering as she gracefully knelt before him.

Before Taro could protest, her slender fingers hooked into the waistband of his pants, tugging them down in one fluid motion. He gasped, too stunned to resist as his cock sprang free, already half-hard from the sheer absurdity of the situation.

"Ahh!!" Grayfia's breath hitched.

Taro instinctively moved to cover himself, but her hand snapped up, gripping his wrist with surprising strength.

"Taro-sama."

Her voice was a velvet command. When he met her gaze, her pupils were dilated, dark with something far more primal than duty.

"I intend to meet your expectations… thoroughly."

A shiver ran down Taro's spine as Grayfia nuzzled her cheek against his dick, her warm breath ghosting over the tip.

"Mmm… So hot… So hard… And the scent!"

The sheer contrast between her usual composed, dignified demeanor as a maid and the lewd scene unfolding now sent a shiver of excitement through Taro's cock, making it twitch against her flawless skin.

As his shaft slid along her smooth cheek, leaving a glistening trail of pre-cum, Grayfia let out a breathy sigh.

"Fuu… To think it's this wild… Even more virile than him…"

Her heated gaze locked onto the pulsating rod, watching it throb with need. Without hesitation, she rubbed her face against it once more, her silken skin massaging his length with deliberate, worshipful strokes.

"How is it…? My cheek service…? But every time I rub, you grow even hotter… even harder…"

Each time his pre-cum smeared across her face, instead of disgust, her eyes only grew more intoxicated—more desperate. Her movements became needier, her breaths more ragged.

And then—
