She merely blinked, and the iron door behind her had transformed into a bed.

“Mmph… wait.”

Heat surged through her body as Rubellan’s saliva slid down her throat. Rael desperately pushed him away when their lips finally parted, but he only pressed closer with each attempt. The bed rocked with every movement of his large frame.

“Stop, that… ah, mmm…”

Rubellan’s lips traveled down her neck, passing over her sensitive nape to reach her collarbone. His hands were already untying her robe, which had been precariously draped on her from the start. His behavior made a mockery of his earlier polite greeting—he was acting like a dog in heat, completely losing his composure.

“Haa… Rubellan…”

Rubellan, who had been admiring Rael like one intoxicated by a drug, smiled faintly at the sound of his name.

“Don’t you know that calling my name in such a tearful voice won’t help your situation?”

His voice was playful, coaxing and teasing.

“Calm down. This isn’t why I came here.”

“I like it when you treat me like a dog you’ve raised.”

“When did I ever…!”

“You want to hold my leash, don’t you?”

Even while speaking, Rubellan’s hands were roaming over Rael’s back, and his lips continuously left marks on her skin. During that brief exchange, her clothes had already been thoroughly disheveled.

“Would you like to hold something else instead of a leash?”

When he implied there was something else she could grasp firmly in her hands, Rael’s eyes widened in surprise.

“That expression is dangerous too.”

What was she supposed to do?

“I’m sorry. Coming here was a mistake. I was just trying to make a living and—”

“Sure. A mistake. Let’s call it that.”

Whether he was listening to Rael or not, Rubellan’s attention was already elsewhere. His lips brushed against her ribs, passed her navel, and moved downward. His mouth traced over her milky skin with sticky deliberation until it reached her lower abdomen. Rubellan’s firm hands spread Rael’s legs apart and positioned himself between them.

“Rubellan!”

Startled by his body moving between her parted legs, Rael urgently grabbed his hair.

“That’s not what I meant you to grab. But whatever.”

Rubellan laughed deeply as he licked her skin, sending vibrations through her body. His lips descended further until they touched Rael’s exposed pink flesh. In an instant, his hot tongue parted her folds and entered. The lewd wet sounds from below made Rael’s face burn.

“Ah…”

Traitorously, her body was responding faithfully to this disrespectful demon. When Rubellan’s tongue pushed into her narrow passage, her raised legs trembled.

“Too… too much…”

The sensation was overwhelming. Rael struggled to swallow the high-pitched moans escaping her. She could vividly feel his tongue wriggling and probing inside her.

Whenever her body turned to jelly from his gentle licking, Rubellan would lightly bite her l*bia, sending electricity through her body. His tongue plunged in and out, sucking greedily while obscene wet sounds assaulted her ears. After thoroughly exploring her tender flesh and stimulating her cl*toris, Rubellan wiped his mouth and raised his head.

“Still delicious.”

Seeing her flushed face panting for breath, he felt a surge of desire to immediately penetrate her softened entrance, but he forcibly restrained himself.

“Senior.”

“Haa… what, what is it?”

When Rael gathered her dizzy thoughts and barely managed to respond, Rubellan slowly pushed his long, smooth finger into her opening.

“Ah…!”

As Rael’s hips jerked upward, Rubellan pressed down on her lower abdomen with his free hand, like a predator pinning down its prey.

“Have you let any other bastard put his c*ck in here?”

At Rubellan’s question, her tightly closed, trembling eyelids flew open.

“Wh-what nonsense!”

“It’s okay. What sin is there in a grown adult having s*x with a man?”

He smiled gently, understanding, coaxing her to be honest. It was like a demon’s whisper, tempting her with the promise of absolution if she confessed now.

“…I haven’t… ugh, done that.”

At Rael’s answer, Rubellan observed her eyes intently, searching for the truth.

“That’s a relief.”

“Now stop… t-take your hand out…”

Rael grabbed Rubellan’s wrist, but mocking her effort, his fingers moved more rapidly inside her walls. His hand, moving back and forth, pressed firmly against a certain spot with practiced ease.

“Ahh!”

When Rael reacted intensely, the smile on Rubellan’s face deepened.

“If I’d found traces of another bastard breaking you in, I’d be scared of what I might do.”

“Wh-what?”

Rael was bewildered by his nonsensical talk, wondering why this demon was acting like she belonged to him.

“If I lose control and pound you until you pass out, you’ll hate me. You’re so delicate you can barely handle s*x twice.”

Rael had many rebuttals. First of all, he was a demon. His physique was fundamentally different from humans. No woman, however healthy, could endure a night of being pounded by that massive organ.

“Ah.”

Rubellan suddenly withdrew his finger. When the hand that had been stimulating her inner walls pulled out, Rael inadvertently let out a sigh.

“Ah. Sorry, Senior. My c*ck is about to burst.”

Rubellan stroked his own member with the hand he had withdrawn. At his words, Rael looked down and saw Rubellan’s organ. The hideous thing was as thick as a child’s forearm, with veins bulging around it, and its tip was already slick with white fluid.

Rubellan slowly rubbed his gl*ns with his thumb. His gaze remained fixed on Rael’s flushed flesh.

“Ru-Rubellan…”

“You looked at me with exactly those eyes the first time I put it in you too. Right?”

Rubellan rubbed his rigid member against Rael’s s*x. The tip rubbed against her entrance, already wet with arousal. After repeatedly touching her cl*toris and slightly pressing the head against her opening before pulling back, Rael began to feel strangely impatient.

“Mmph… Ru-Rubellan.”

She was unconsciously urging him on. The teasing object that only knocked at her entrance was driving her crazy with anticipation. Her depths tingled with desire. She wanted his thick member to scratch that itch thoroughly. No matter how much time had passed, her body remembered the extreme pleasure it could provide.

Her twitching entrance welcomed the gl*ns as it gradually pushed deeper.

“The path I worked so hard to clear has all closed up.”

His voice was regretful.

“Ah… q-quickly…”

Rael, now consumed by desire, was pleading with Rubellan.

“Quickly? What do you want me to do?”

“Quickly… mmph…”

Rael trembled as his member pushed a little deeper.

“You have to tell me what you want, Senior.”

Rubellan’s lips, curled up mischievously, approached Rael’s. When she opened her mouth and eagerly licked his lips, Rubellan laughed softly. Rael instinctively craved his saliva. She was reacting reflexively, knowing how it could reduce the pain and enhance the pleasure.

“Do it…”

“How do you want me to f*ck you?”

“Ha… just… quickly.”

Her head was spinning so much that Rael didn’t even know what she was saying.

“Sounds like you want me to pound you roughly.”

“However you want…”

Now almost whimpering, Rael moaned pathetically, and Rubellan, who had been stroking her hair, strongly gripped it.

“Don’t worry. Even without you saying it, I’ll make you cry all night long.”

His thick member, which had been teasing her entrance, violently parted her tightly closed walls and pushed in.

“Hng…!”

Her opening, stretched to accommodate his overwhelming size, cried out in pain. It hurt. It felt like she would die from the pain. Physiological tears flowed from Rael’s eyes. Rubellan licked them away with his tongue. But even though she tried to hold them back, the tears continued to flow without pause.

“Ah…Ah! Hic…”

His member split her walls tightly and pushed in to the root. When Rubellan slowly moved his body back and forth, her inner walls, which had been screaming in pain, began to faithfully accept the pleasure of his member rubbing against them.

“Ha. How is it, Senior? Your insides seem very happy to see me.”

The pain gradually faded, and a strange pleasure climbed up her spine. As Rael’s insides became wet, his hips moved without mercy.

“Mmph… haa…”

Rael had no strength to answer. With his irregular thrusts, she could barely breathe, let alone gather her thoughts.

As Rubellan’s hips increased their speed, fluids and s*men thoroughly soaked his t*sticles. Each time he thrust his member to the root and pulled out, the overflowing liquids splashed loudly.

“Mmph… too fast. S-slower.”

“That’s what’s so cute about you, Senior.”

“Hnngh.”

Rael felt like she would die from the pleasure that overwhelmed her after so long. She clutched Rubellan’s arm tightly, gripping it like a lifeline.

“Your body clings to me so lewdly, yet you say it hurts, it’s painful, you don’t like it—how adorably contradictory.”

Rubellan whispered in a gentle voice that contrasted completely with the rough situation below.

“It makes me develop sadistic tendencies I never had before.”

When he expertly thrust deep into her sensitive spot, a gush of sticky fluid burst from Rael’s heated entrance. As her trembling body convulsed briefly, Rubellan abruptly pulled out his deeply embedded member. Clear liquid mixed with whitish fluid flowed from where his member had withdrawn.

“Haa… ha.”

Rael breathed heavily, overwhelmed.

“The sheets are all wet.”

“Ah…”

Rubellan’s face approached Rael’s s*x. His fingers spread her folds, which still radiated heat. One hand continued to massage his own member, which remained rigid and painful.

“Still so luscious. It’s amazing how this tight, cute thing can take me in.”

His voice, filled with composure even in this situation, completely mismatched his eyes dripping with lust.

Just as her breathing began to return to normal, the brief respite ended. Rubellan’s member, which had grown even larger during the pause, invaded Rael’s entrance. Her hypersensitive walls could feel every throbbing vein. The squelching sounds intensified.

“Ungh!”

“We’re still far from done.”

Why did those words sound so terrifying?

Rubellan ravaged Rael’s insides roughly, showing no more mercy. Each time he thrust deep and pulled out, her inner walls clung to his size, exciting him further.

“Ahh! Ru-Rubellan! Mmph! Ha…!”

The man’s normally composed eyebrows twisted slightly when Rael experienced her second org*sm.

Around the time Rubellan felt like his brain had turned into his c*ck from the ecstasy of Rael’s insides squeezing him tightly, he thrust upward, pushing in as deep as possible. With a short groan, his body trembled, and hot s*men filled Rael’s womb to the brim. The excess that couldn’t be contained leaked out of her entrance.

“Hnng.”

Even after emptying himself thoroughly, Rubellan continued to move his hips slightly. After a while, when he pulled out his member slowly, the copious amount of s*men he had released overflowed with a gurgling sound.

Rael wanted to close her legs under his staring gaze, but she didn’t have the strength to move a finger.

“After feeding you so much. What a waste.”

Rubellan clicked his tongue. Then he used his finger to scoop up the s*men that had flowed down to her anus and pushed it back into her entrance.

“Wh-what are you doing!”

Startled by this action, Rael shouted, and Rubellan licked the remaining fluid from his finger before speaking.

“It’s okay, Senior. I’ll fill you with so much of my s*men all night that it replaces the water in your body.”

It was madness. Rael shook her head as she looked at Rubellan, who spoke with a normal face but had clearly lost his mind. This was truly wrong.

Perhaps Rael should have realized by now that she had fallen into a major trap.

“It’s been so long since we’ve met. You’ll understand if I’m a bit greedy, Senior.”

Rubellan looked down at the astonished Rael with an affectionate smile. Then he brought his once again er*ect member to her slick entrance, which hadn’t even fully expelled his s*men, and gently rubbed against it.

“Oh, by the way. Did I mention?”

His gl*ns was already parting her walls again, which hadn’t had time to cool down. With a squelch, the moist area welcomed the member it had already tasted.

“Morning never comes to the Demon King’s Castle.”

In the dark castle, where not a single ray of light had entered since her arrival, only Rael’s moans echoed endlessly.
