“Haah…”

The thick, rugged member filled her inner walls completely. No matter how she moved, the feeling of fullness in her belly made it hard to breathe.

Rael collapsed onto the grass, and before she could worry about damaging the flowers, Rubellan’s manhood mercilessly struck her most sensitive spots.

“Ah! Ugh… hah!”

As cries of pleasure escaped Rael’s lips, Rubellan stroked them with his thumb, then slipped his finger between her parted lips. Instinctively, she sucked on it.

Rael couldn’t understand why she felt compelled to suck on whatever entered her mouth, but she guessed it might be an instinct to distract herself from the pain and pleasure hammering her lower body. The wet sounds of her sucking his finger leaked into the air.

“Sucking my finger with your mouth while squeezing my c*ck below. Senior really does eat everything well.”

“Ha…. mmph…. hnngh!”

She couldn’t respond. As he said, Rael was completely focused on sucking the finger filling her mouth. Each time the swollen head of his manhood scraped against her inner walls, she trembled with ecstasy.

Rubellan withdrew his hand from her mouth. Feeling empty without something filling it, she looked up at him.

“Don’t suck too well. I might want to put something else in there.”

“Hm… I don’t want that. Ah, ah!”

“That’s right. Keep refusing. The thought of you working that small mouth around my c*ck makes me want to pound you until you can’t breathe.”

Despite his vulgar words, Rael’s body was becoming more aroused.

“Then kiss me instead. So I won’t want to put anything else in your mouth.”

Rubellan laughed deeply. The vibration transferred through their connected bodies, transforming even that into pleasure.

At his threatening words, Rael gripped his shoulders tightly and pulled him down. His body fell forward, driving his manhood deeper inside her.

“Haah!”

As her legs trembled from the pressure, Rael tried to catch her breath while Rubellan subtly rotated his hips.

“Ah! Wait… ugh! Stay… ha.”

Tears finally rolled down Rael’s cheeks. Rubellan wiped them away with his thumb.

“I like it when you cry and beg. I was almost disappointed that you were taking it so well.”

You perverted bastard!

Rael glared at him through blurry eyes. But she had to close them again when he resumed thrusting.

“Ugh…”

Wet, squelching sounds continuously emerged from their joined parts. Her sensitized skin bristled at the mere brush of Rubellan’s clothes.

“Ha… ah… hm…”

Feeling her brain tingle, Rael shook her head. Rubellan bit her earlobe. The slight pain made her body twitch and her inner walls contract.

“Ah. If you squeeze like that, I might finish. Do you want this to end quickly when you’re enjoying it so much?”

The low voice directly in her ear made her body shudder.

“This is why I want to pound you like a dog in heat. Being inside you feels so good it’s maddening.”

His voice was drenched in ecstasy. Like someone intoxicated, Rubellan was fully immersed in the pleasure. Though normally inscrutable, during s*x he became transparent as an animal following its instincts.

But Rael’s reason had long since evaporated too. Even as Rubellan’s thrusts grew rougher, she felt no pain. Instead, she whimpered at the overwhelming pleasure, drowning in the ecstasy he provided like a beast sinking into a swamp.

“Ah… Rubellan…”

When his name escaped her lips, Rubellan bit down hard on her small, white shoulder.

“Ugh!”

As Rael flinched from the pain, her inner walls tightened, and Rubellan released himself deep inside her. Though he stopped moving, Rael lay limp, her mind completely blank from just one round of lovemaking.

Rubellan quite liked her unfocused eyes, hazed over with pleasure. When he pulled out his manhood, their mixed fluids flowed out. The pungent scent of arousal remained sharp even among the trees and grass.

All Rael could see was the green grass surrounding them. The greenhouse scene seemed too peaceful to believe they had just committed such a sinful act, making it feel unreal.

What drove her even crazier was how incredibly good s*x with him felt. Could she ever experience such breathtaking pleasure with someone else? At this rate, she might become addicted and willingly serve as the demon’s slave.

‘This is maddening.’

The fact that she was already feeling anticipation from the demon’s hand gently teasing her lower parts again was clearly problematic.

Stockholm syndrome, wasn’t it? Or perhaps she was simply bewitched by the demon.

“Ah… ugh!”

Her dizzy thoughts were completely erased as his manhood, somehow already hard again despite having just released, parted her slick entrance.

* * *

“What’s that?”

Rael was looking out the window in the corridor of the Demon King’s Castle. Rubellan had allowed her to wander inside the castle due to her docile behavior. Since the main gate was locked anyway, letting her small feet explore here and there was no problem for him.

[That’s a flame caterpillar!]

“It’s wriggling. Cute.”

[Nonsense! If you touch it, worm-like creatures will crawl out from its back and attack you!]

“Ugh. That would be disgusting.”

[Don’t just grab anything you find cute! Human!]

Today’s conversation partner was Joseph. Rubellan, being the Demon King after all, occasionally left the castle for work. Fortunately for Rael, she didn’t have to be with him all day—she might have suffocated otherwise.

“Surely that large flower isn’t a monster too?”

Rael pointed to a large flower blooming in vibrant red and yellow.

[If you had touched that flower with your finger, it would have dissolved!]

“Wow. Brutal.”

Nothing visible seemed safe.

“I bet if a human walked into that forest path, their flesh would melt instantly?”

[Of course!]

The forest path to the east: absolutely do not enter.

Rael was slowly gathering information while exploring potential escape routes. The opportunity would surely come, if not now then later.

“Then what about that lake? The water sparkles beautifully.”

A lake was elegantly situated to the west of the Demon King’s Castle.

[You’d faint if you knew what was in there.]

“…How intriguing.”

[It’s perfect for disposing of humans who foolishly enter the Demon King’s Castle! Throw them in, and fish that devour even bone fragments swarm them in less than three seconds!]

“They have quite an appetite… indeed.”

There was nothing more to ask. The western lake area: don’t even set foot near it.

“Why is everything frozen over there?”

She didn’t need to ask about the north. The mountain was completely frozen solid, and without explanation, she knew stepping there would turn her into an ice statue decorating the mountain.

…Looking closely, it seemed like some of those weren’t actually trees frozen in place.

[The Demon King froze all the noisy monsters on the mountain.]

“Rubellan did?”

[The Demon King hates noisy things!]

“I see…”

She would need to be somewhat quiet from now on.

“By the way, how are you still around?”

[What do you mean, human?]

“He hates noise, right?”

Joseph tilted his head in confusion at Rael’s words.

“You’re extremely noisy.”

[You human!]

Finally understanding her meaning, Joseph jumped up and down on the windowsill, fuming.

“I’m joking.”

When Rael gave a playful smile, Joseph stared at her blankly.

There was something peculiar about this human. She was irritating but not dislikable, and even when she teased a demon like this, he couldn’t bring himself to hate her.

[Well, what a talent.]

“Hmm?”

[Never mind! Human! Go get your snack!]

And thus, he ended up providing three meals a day plus snacks to a mere human.

“Why such a hurry? We have plenty of time.”

Wasn’t that attitude strange too? Normally, humans trapped in the Demon King’s Castle wouldn’t maintain such a relaxed, leisurely attitude.

The humans Joseph knew were stupid and cowardly creatures. He thought this human must be quite extraordinary.

[True. You need to be at that level to be suitable company for our Demon King.]

Joseph, who had initially despised the idea of keeping a human around, had forgotten his original objections and was adapting to life with Rael.

* * *

When she woke from a late afternoon nap, Rubellan was sitting in a chair, legs crossed at an angle, looking down at her.

“What did you do today?”

“Well, chatted with Joseph, ate meals, had snacks.”

She wasn’t particularly pleased with him watching her silently.

“What else?”

“Explored the castle too.”

“Was it fun?”

Rubellan unlaced his fingers and brushed back some stray hair. His sleek black hair flowed like waves.

“It was boring.”

Why ask such an obvious question?

As Rael slowly got up, Rubellan also rose from his chair. The moment he stood, the chair vanished into smoke.

Really, such a waste of magical power when he could just leave a chair in the room.

“Shall we go out?”

Rubellan placed his hand on Rael’s arm as he spoke, but she slapped it away with a sharp sound. Rubellan looked at his stinging hand.

“That hurts my feelings.”

“You can feel hurt? A demon?”

Rael answered with a bright smile.

“If it comes from you, Senior, I’ll gladly accept it.”

His slippery response made Rael realize anew that he was no easy opponent.

“I’ve seen enough of the castle to be sick of it.”

Watching Rael change the subject coyly, Rubellan raised the corner of his mouth. His attitude suggested he could see right through her small mind.

“Outside the castle.”

“Seems like we should leave right away then?”

Rael walked lightly toward the door. She even gave him a look, seemingly asking why he wasn’t coming out yet.

“So transparent, really.”

Rubellan followed her with slow steps.
