Tenebrous Wolf

Briar felt like a rabbit cornered by a massive wolf.

First, she had been forcefully summoned into the human world. Then, before she could even grasp her situation, she was bound into a Master-Servant Soul Contract with a human!

And just when she thought things couldn't possibly get any worse, she was now suffering the consequences of rejecting the contract. The curse was in full effect, flooding her body with an unbearable heat, and her limbs trembled from the aphrodisiac effects.

To make matters even more infuriating, there was only one way to make it stop. She had to accept the human before her as her master!

The mere thought made her want to scream.

How had a barely tolerable morning spiraled into this?!

Wha... Wh-what is he planning on doing?

Seeing the fierce smile on Klaus's lips, Briar felt a terrible premonition rising from her stomach.

Before she could react, before she could even process what was happening—

"Wha—?!"

The world tilted.

In the blink of an eye, she found herself bent over, her front pressed against the bed, hips raised high.

Her breath hitched.

She wasn't even sure how it had happened. One moment, she was standing, and the next… this.

To any outsider, it would have looked like she had willingly presented herself. Or her butt rather.

She was so confused about what had happened that her thoughts came to a stop temporarily.

On the other hand, Klaus, who was enjoying the pleasant view said,

"Damn." His tone was casual like he was appreciating something. "I knew you had a ridiculously huge ass, but being this close… yeah, it's even bigger than I thought. Is this all natural?"

For a second, her brain completely short-circuited.

Then—

"You—!!"

Briar snapped her head back to glare at the infuriating human—

And then, she froze—!

Her breath shuddered in her throat, and for a moment, it felt as if she had completely forgotten how to breathe.

"...!!"

At some point, Klaus had shed his clothes, leaving him completely bare. His above-average physique was hardly impressive—at least, not to her.

After all, members of the demon race possessed far more developed bodies than mere humans. Compared to them, Klaus's form was nothing remarkable.

The real issue, however, was the… thing standing proudly in front of her.

A beast of a weapon, which was thick and intimidating, aimed at her face like a dragon preparing to breathe fire.

A giant rod which was Klaus Schwarz's manhood, 23 centimeters long and extremely girthy.

Her thoughts completely blanked out.

What… What the hell is that...? Totally stunned, a bead of sweat rolled down Briar's forehead.

Noticing her reaction, Klaus's lips curled into a satisfied smile. Upon awakening as an Apprentice-rank Ascendant, his body had undergone a complete transformation— his physique, his five senses, especially his sense of smell, had been enhanced to an extraordinary degree.

No, they hadn't just improved. They had been rebuilt from the ground up.

That was the result of the phenomenon known as Awakening.

Of course, since his physique had been reconstructed, his proud manhood was also included.

Klaus spoke with a mocking smile,

"Why are you staring so hard? Do you like it? Honestly, even I'm surprised. I never thought it would end up this big. This wasn't included in the data books. But I'm guessing you haven't seen anything like this before, correct?"

Briar was silent for a bit due to shock, but she soon regained her composure and laughed.

"Ha! That arrogant smile of yours is hilarious. You might feel confident, but compared to most demons, you're nothing special."

She flashed a smug smile, expecting a reaction.

But contrary to her expectations, Klaus merely shrugged.

"Perhaps. According to the basic information provided by the government, demons naturally surpass the human race in physicality alone. So that doesn't surprise me."

Briar's smile faltered, her brows knitting into a frown.

What's with this guy?

Her attempt to provoke him had completely fallen flat.

Had she said this to a demon, they would've taken offense and probably thrown a fit. But the human in front of her remained perfectly calm, as if her words were nothing like the night breeze.

Where the hell was his pride? Are all humans like this…?

The thought sent an unexpected shiver down her spine.

In the next second, Klaus did something that shocked her. He firmly grasped her ass, squeezing and kneading her soft, plump flesh.

Briar yelled weakly, her face still flushed red. "You...! what do you think you're doing?!"

"Don't you already know? I'm going to break the curse."

"What does breaking the curse have to do with touching my ass?!"

"Oh, you sure are lively. Do you really want me to stop, though? Your face is as red as a tomato."

"My face is flushed because of the aphrodisiac effect of the curse! Also, I'm like this because of you!"

Klaus shook his head.

"No. You're like this because you refused to answer my question and are actively resisting the Soul Contract. If I leave you like this, your mind will break under the rapidly increasing aphrodisiac effect. So I have to soften you up by doing something like this, okay."

He explained everything smoothly while massaging Briar's fat, soft asscheeks. They were so big and round that his hands could barely contain them. No, even that was wrong.

Even with both hands, he could only grasp a fraction of their fullness, and the plush flesh spilled between his fingers as if defying his grip entirely.

Certainly, it was a giant butt that surpassed humanity.

Briar averted her gaze and bit her lower lip to stifle any moans from escaping. Klaus was merely squeezing her ass— firmly, of course. With how massive it was, a gentle touch would be meaningless. But that rough treatment, the way his strong grip sank into her soft flesh, sent an unfamiliar shiver through her body.

Unbeknownst to her, his actions were stirring something deep inside that she hadn't expected, arousing her to unimaginable levels.

Damn it... I have to do something before he really tames me...

Briar tried to calm her chaotic thoughts while controlling her moans.

However, her attempt truly became meaningless as she felt a strong impact on her left asscheek, so hard that it might even leave a handprint.

"You…! H-How dare you…?!"

Since she couldn't move, Briar could only turn her head and glare at Klaus, but he only smiled.

"Sorry. I just couldn't control myself. I mean, your butt is really inviting, so it can't be helped. Besides, it's obvious you're enjoying it, so I thought it was okay if I was a little rough."

"Fuck you! Why the hell do you think it's appropriate to— Uhhhhhhhhhhhhhhhhhhhhh!!"

For the second time, the demoness was silenced.

Without warning, Klaus savagely pushed his hips toward her defenseless ass before she could finish.

His pelvis, already lined up on her backdoor, spread aside her meaty ass cheeks and penetrated deep into her tight butthole, stretching it and invading her bowels in an instant.

The result of that action caused Briar to release her sweetest and loudest moan. For a second, even her vision went blank.

"Ahhh! Wh... what is this?"

Feeling an unexpected, unimaginable pressure and resistance, Klaus groaned and felt like if he wasn't careful, he would cum in a second.

Indeed, shoving it inside without thinking was a big mistake. In fact, he didn't know why he did that.

It almost felt like he was influenced by something.

Damn it. Why the hell is she this tight? She has no business being this tight...!

Klaus realized the situation and tried to pull out, but the succubus's ass squeezed his dick so hard that it was extremely difficult for him to pull out without climaxing first.

As a result, he had no other choice but to remain still inside her for a brief moment.

He gritted his teeth to suppress a groan, while the succubus bit onto the sheets, and gripped them so hard that her knuckles almost tried white.

It seemed as though the two didn't want to cum before the other.

"Damn… You're too tight. Do you mind loosening up a little?" Klaus muttered as he slowly pulling out.

"I'm… ngh— not the one who… ah~ told you to shove your damn thing into my ass, you big jerk...!" Briar retorted between moans, trembling under the overwhelmingly sweet sensation.

"Such strong words for someone who's clearly enjoying this. You're not entirely innocent either."

To emphasize his point, Klaus gave her ass a firm squeeze, drawing a muffled moan from Briar as she bit down on the bedsheets.

"So what do you have to say for yourself? I could pull out right now, but I don't think you would be satisfied with that, yes? Especially in your current condition."

"Tch."

Briar clicked her tongue, biting back her moans as she struggled to regain composure. After a brief pause, she finally spoke.

"Ju-just... do what you have to..."

To Klaus's surprise, she agreed. Maybe she thought that cooperating, even for a moment, would help them end this situation faster.

"Alright."

Reading her intent, he tightened his grip on her massive buttocks, sinking his fingers into the plush flesh as he kneaded and groped the soft globes. Then, he began moving—slowly at first—pushing in and out, spreading her ass apart with each thrust as he sank deeper into her tight, clenching hole.

He noticed something as he continuously rammed his fully erect cock into her. Wet fluids were dripping down Blaine's thigh from her pussy.

As if to confirm something, he slapped her butt. Her body shivered slightly. Even more fluids escaped her pussy, and her grip around his cock tightened.

Observing this, Klaus smirked. "So, you like it rough, huh?"

He grabbed Briar's buttcheeks tighter, eliciting an 'eep' and another quick glare before he finally settled his position and began to pound her ass without saying a word.

His thick, long phallus made its way through her bowels, reaching places Briar didn't know she had. The succubus experienced a pleasure she never imagined could be felt through the insides of her backdoor.

He went slow for a few moments, testing her hole with his impressively veined thickness, pleased that her rosebud tightened around his shaft but, more importantly, dilated quite well as he shoved his manhood as deep as her tightness and meaty buttocks would allow.

"Fuuucck~ It's so big... and... fat..." Briar murmured beneath the escalating pleasured moans she couldn't suppress.

Emboldened by this, Klaus abandoned any pretense of gentleness. He increased his pace dramatically, and slammed his awakened dragon into her backdoor with renewed vigor.

The rhythm transformed from a measured exploration to a relentless pounding. He moved with the force and regularity of an industrial piston. Her large, rounded ass became the target of his increasingly forceful advances, sending tremors through her body.

The sounds of flesh on flesh, the wet squelching of their mingled fluids, and Briar's involuntary moans, Klaus's groans included, filled the room.

It was a vicious pounding with no brakes or mercy!

It would be surprising if the whole neighbourhood heard them due to their loud moans!

Klaus noticed that the succubus could handle his powerful thrusts against her massive backside incredibly well, so he saw no reason to hold back.

The sight before him was almost mesmerizing—his thick length, glistening with a mix of their fluids, plunging into her tight, clenching hole. Her plush, ample ass rippled with every impact, his broad pelvis spreading her apart with each thrust.

His manhood was enveloped by Briar's scorching heat and her insides which gripped him like a vice, as if trying to trap him within.

He grunted as Briar's moans grew louder with each stroke, her voice carrying a mixture of pleasure and strain. Though his sheer size stretched her tight tunnel so much, the real challenge came whenever he tried to pull out.

Damn… I can't pull out. it's like her ass is sucking me in.

Klaus thought with a husky breath, feeling her walls clamp down as if refusing to let him escape!
