As A Result of Trying To Live An Erotic Slow-Life, I Have Become The Underground Ruler of This Upside-Down Otherworld - Chapter 72: Chapter Three Interlude: Do-Anything-For-A-Day Coupon - Serika

Chapter 72: Chapter Three Interlude: Do-Anything-For-A-Day Coupon – Serika

Serika, the woman, was in distress.

Her desires equate to Arius’s desires—a formula etched not just in her mind but in her soul.

To put it bluntly, she has no personal desires. If pressed, she’d say she wants to be someone who can swiftly act on Arius’s wishes.

If he said, Go kill that guy, that day would be their last.

If he said, My dick’s itching, use your mouth, she’d kneel instantly, opening her mouth to receive his desire.

She’s a tool. She wishes to be the most convenient tool for Arius, polishing herself daily for it.

To be the spear that pierces his will, the sword that fells dangers, the shield that protects him, and the flesh that comforts his body and heart.

“N, nu… W-What do I do?”

No desires come to mind.

Shuri genuinely didn’t know her wish.

But for Serika, it’s clear—she has none. That’s the fundamental difference.

For Serika, her desire is already fulfilled, and anything she wants now must be seized by her own hands to have meaning.

The gods of this world didn’t save Serika—or perhaps chose not to.

It’s unclear, but the fact is, it was Arius, not a god, who saved her.

Devout followers might claim their meeting was divine guidance, but Serika doesn’t buy it.

If someone said her meeting with Arius was a god’s work, she’d cut their head off in seconds.

To Serika, the gods known in this world are far beneath Arius.

If gods have a hierarchy, Arius shines as number one, the only one.

And the salvation brought by such a god.

Arius, her god, is kind. He always cherishes them.

So, she doesn’t quibble with Towa’s words that offering desires proves faith in Arius.

But she doesn’t accept it.

Towa, Mia… maybe even Shuri, using the coupon to fulfill their desires? Fine, she’ll concede that much.

But not her. That’s all.

“That’s why, though…”

She doesn’t accept it, but she understands this is Arius’s wish too.

It’s like he’s seeking a chance to connect more deeply with them. Though she can’t articulate it, Serika senses his intent.

She’s always fully open to him.

Anytime, anywhere, she’s ready to welcome him, but there’s such a thing as sentiment.

Serika isn’t one to care much for such things.

Still, this is Arius’s wish.

She must respond with her whole being… but nothing comes to mind, and she’s stuck in this cycle of distress.

“Nn… Alright, then.”

After agonizing, she arrived at one answer.

That answer was—

※

Now, abruptly, Arius is a half-orc, half-human.

Orcs are famed for their sexual prowess, but another trait is raw strength.

As a half-orc, Arius can’t punch down trees, but he’s stronger than average. In his past life’s terms, he could crush an apple one-handed or lift heavier than his body weight with ease.

If it’s Mia’s weight, he could carry her on his back or in his arms all day without issue.

So, Serika’s conclusion was…

“Nu♡”

“…Uh, Yuri’s, y’know, at Rongrong for the day.”

“A-Ah, yeah. Sorry? Thanks.”

To become Arius’s cock sleeve.

For the kids’ sake, precautions were needed, so Yuri, with Mia and Shuri, was sent to Rongrong for a sleepover “social study.”

“A, Arius-sama…♡ K-Knocking…♡”

“Uh… Yeah, yeah, you’re my dick holder today, right?”

“Hiu♡ S-Sorry♡”

A baby carrier, maybe?

Serika clings to Arius’s front, secured by straps.

Arius mentally apologizes to all mothers worldwide.

“A…♡ Ha…♡”

“Look, I said anything goes, so… it’s fine, but…”

Serika’s trembling breaths tickle Arius’s chest as she moans softly.

Arius feels ticklish, but her massive breasts, pressed and squished against him, feel so good they make his groin harder.

“Afu♡”

Even that slight change makes Serika’s body react.

Her flesh pot licks and pulses around his shaft, eager to milk him.

Truly a pussy customized for Arius.

Supporting Serika’s weight is no issue, as mentioned, but he struggles not to spill his seed carelessly.

“Uh, s-so… what about food?”

“Well, gotta eat, but… Serika?”

“A, ae♡ I-I’ll eat, too♡”

How, though? Arius and Towa hold back the urge to retort.

Serika was already gone.

When Arius walked, her juices dripped pota pota onto the floor, soaking wet, her speech slurred.

Her thoughts weren’t coherent—her open mouth, tongue lolling, eyes heart-shaped.

“No way… Sorry, Towa?”

“Y-Yes. Then, excuse me.”

“Nhyu!?”

Giving up, Arius sits. The jolt makes Serika climax.

Ignoring that, Towa sits beside him, stabbing food with a fork.

“Here, Goshujin-sama, ahh.”

“Ah… Nmu, ngu. Yeah, tasty.”

“Thank you.”

She feeds Arius.

Frankly, even Towa’s shocked.

No, she’s jealous—she’d want to try it herself.

But she’s not confident she could ignore her surroundings like Serika.

Single-minded devotion, perhaps.

Serika was fully focused on her role as a cock sleeve.

“Ah…”

“Here’s more…”

More food to Arius’s mouth.

While chewing, Arius realizes what to do.

“Ngu… Sherika, here.”

“Ae? A-Ah… Nnmu!?”

How can Serika eat like this? Only by mouth-to-mouth.

“—♡”

Food mixed with Arius’s saliva.

Swallowing it mouth-to-mouth, Serika faints again.

“A, ahe… A♡”

“Alright, next one.”

Overwhelming bliss.

The sensation of being filled by Arius.

Truly, Serika could die here and be content, melted completely.

“U, uu…”

“Haha… Yeah, sorry, Towa.”

Towa’s female instincts stir, her thighs rubbing moji moji.

For Towa, it’s hell—she must tend to them without her own pleasure.

—After this, I’m definitely masturbating.

In this odd multi-person play, Towa recalls Serika’s past feelings, reflecting oddly while…

“Ariohyu, shama♡ Wond’ful♡ Love♡”

She glares at Serika, adrift in waves of pleasure.

※

It’s pervert play, plain and simple.

Their connection was broken only for bathroom breaks.

Well, broken, but Serika tried to take Arius’s waste in her mouth, even wanting the smaller one directly.

Arius isn’t into scat. Shuri’s case made him consider piss play, but…

Still, they stayed connected.

Unlike usual, Serika didn’t roar like a beast, and Arius felt she was trying to hold herself together until the day ended.

Out of mischief, he’d grind her weak spots to make her faint or piston through ejaculation—her favorite—but…

Even so.

“…Fuu.”

“…A, u…♡”

Even when the promised day ended.

“Serika? You okay?”

“A… Hai♡ Thank, you♡”

She held onto consciousness until the end.

Arius gets it now.

“Jeez… You’re too much for me, really.”

It wasn’t about wanting a sex-soaked day.

He doesn’t know its full meaning, but this day was necessary for Serika.

“I, I… Was I, Arius-sama’s, t-tool? Did I, feel good, make you comfy?”

Arius nods with a wry smile at her words.

“Best ever. Pass. Perfect score, no complaints.”

“R-Really… Ehe, yay…”

Serika smiles innocently, like a child.

In the end.

Serika sought a trial.

She knows Arius, her gentle god, would call her the best without this.

Indeed, Arius meant to say it was the best, not flattery, but truth.

That’s why Serika tested if she could be his tool now.

She knew her beloved god never tests them or measures them by worth.

Her incubus traits morph her body to Arius’s liking daily, but even if not fully there, she set her heart on passing if she stayed conscious.

“Hey, Serika.”

“…”

No reply to Arius’s words.

The word pass sank her consciousness into the mud.

“…Jeez.”

Knowing she’s asleep, Arius’s mouth doesn’t stop.

“You don’t have to be a tool, y’know, Serika.”

Even if she were awake, it wouldn’t reach, so it’s fine.

“Just… being beside me is enough.”

Serika thinks she needs this to stay beside him.

But Arius wishes for her to be there, no reason needed.

“Gotta keep up.”

Gently stroking Serika’s peaceful cheek.

“Goodnight.”

He falls asleep, holding her close.
