Tenebrous Wolf

Sasha smiled as Klaus lasted longer than she anticipated. She'd expected him to climax with just the initial movements, but he'd managed to hold on.

"Oh my, aren't you a lively one? I thought you would be gone in with just that?"

Klaus laughed with a cracked smile. "Ha! Don't look down on me, you old hag. I used to have a girlfriend, you know."

"Are you talking about Kelsey?"

"Who else would I be talking about? But I'd rather not discuss her."

"I understand. She's the… woman who left you for someone else, yes? But tell me, how does my pussy compare? Surely, it's tighter than that little cheating… hoe, yes?

Klaus frowned at her arrogant words. He'd never seen Sasha act like this before.

He thrust his hips upwards, silencing her with a loud moan as he hit her cervix again. Of course, this was simply futile resistance.

Sasha grew even more excited and licked her lips eagerly.

"Now, that's the spirit! Keep going like that, and I might get serious."

What did she mean by that? She hadn't been serious?

Before he could fully process her words, She suddenly tightened her grip on his shoulders and increased the pace of her hip movement. Her rear lifted until the tip of his cock was almost out of her tight, eager snatch, then slammed down on his hips, a rougher impact than before, causing Klaus to groan louder.

As she rode him, gradually increasing the speed, her buttocks bounced freely, even making a clapping sound as they slapped together.

Soon, Sasha felt his glans hitting her cervix again, but harder. Each subsequent slam produced the same sensation. Her folds gripped his girth tightly, almost tearing at his proud shaft.

Though that didn't stop him from reaching the entrance to her womb each time Sasha established a steady rhythm. So, she focused on slamming down as hard as she could, rather than simply going faster.

Completely driven by unsuppressed lust, she wanted him deep inside her womb!

"More! More! Just a bit more and you- aahn!

The last word trailed off as her Klaus's cock finally entered her womb.

That was when Sasha let herself go, slamming down harder and harder, forcing his thick cock-head deep inside. She couldn't help but let her tongue loll out and press her breasts against his face, partially suffocating him. She also began to moan along with him, feeling her own orgasm building quickly.

That gave her enough enthusiasm to become even more intense, and she succeeded. Her rear actually began to ripple as her breasts completely cut off Klaus's breath. She was bouncing so hard her buttocks were reddening from the constant impact against his hips. Below her, Klaus regained some strength, at least in his hands, and grabbed her huge breasts, attempting to move them aside and get some air.

Unfortunately, that move backfired as Sasha pressed her breasts against his face with even more force and rode him with long, slow, but powerful slams.

"Ahhn! I'm about to cum!" Klaus groaned beneath her.

But Sasha barely heard him. Her excitement had reached a fever pitch; a mere touch would have sent her over the edge. That, combined with the intense pleasure of his thick cock ramming into her womb, brought her to climax.

And not just her. Klaus, the poor fellow being ridden mercilessly with no brakes, had held back for too long. When Sasha's folds tightened around him, he could no longer resist.

"Yes, just like that! Fill me up!" Sasha shouted in pleasure.

A moment later, with a deep groan, Klaus grabbed her huge buttock firmly and released his accumulated load into her womb.

Wave after wave of thick, white fluid shot directly inside her. Though he had more than enough to drown her, some of his semen, due to the tight grip of her cervix on his thick shaft, ran down her folds and length, escaping her soaked vulva and spilling onto his crotch.

This continued for a few moments, during which Sasha's body trembled as she gasped, trying to regain her composure.

Once she did, after a long breath, she lifted her breasts from his face. Simultaneously, she shook her hips around a bit before rising slowly, freeing his cock from her vagina with a 'pop' sound.

"... Hah... Hah..."

Klaus looked utterly exhausted, as if he'd been through hell. This woman who called herself Sasha had ridden him so hard he thought he might die.

He glanced down, noticing his cock was still stubbornly erect, pointing towards the ceiling.

Why won't it calm down? he thought in confusion.

But that thought was quickly forgotten as Sasha aligned her vulva with his cock. After teasing the tip with her labia, she slammed her hips down, burying his thick rod to her cervix with a groan from Klaus.

His eyes widened in confusion, as if asking, Wasn't that enough? But Sasha only smiled

"Why are you looking at me like that? Surely, you didn't think this would end with just one round, did you~?"

"Wh-what...?"

For a brief moment, Klaus's brain completely short-circuited before his eyes widened in horror.

She was… going to do that again? he thought in desperation.

"W-Wait! Wait! Sasha, please calm down!"

"I don't wanna~"

"Damnit! Get control over yourself, woman! If you continue like this, my pelvis will definitely break!"

"In that case, I'll break your dick then. I don't care anymore!"

Shit! She's not listening at all!

Klaus noticed the strange, unrestrained, wild look in Sasha's eyes.

She looked like someone who had abandoned all sense of reason and completely surrendered to lust. He had underestimated just how horny she truly was.

"Ahn! W-Wait— Ghhhnn!!"

Klaus groaned as Sasha lifted her hips high before slamming them down onto his pelvis, instantly engulfing him with the clear intent of crushing his cock!

† †

For six straight hours, without a single break, Sasha rode him relentlessly until his cock finally went limp.

Even then, she only stopped when, in the midst of giving him head, she snapped back to reality and panicked at the sight of his deathly pale skin.

It was as if something had unlocked her deepest desires, causing her to act irrationally.

In the end, they got dressed in silence, and Sasha escorted Klaus to the door.

He looked like a war veteran returning from the battlefield. Or rather, like a man who had been thoroughly drained by a ravenous vampire.

His unfocused eyes and calm smile suggested he had glimpsed the afterlife and somehow found his way back.

"Well... that was something," Klaus muttered weakly.

"... Yeah..." she replied.

Following that short exchange, the two became silent.

Just like that, an awkward atmosphere had formed.

Under normal circumstances, Klaus would have been the first to break the silence, shifting the subject to something else. But right now, he was too weak and utterly drained to even think.

Sasha hesitated and scratched her deeply flushed cheek. "Um... you should get some rest."

Klaus gave a slow nod, barely managing to lift his hand in a half-hearted wave. "Yeah... probably a good idea."

She opened the door for him, and he staggered forward, stepping out into the outside world. For a moment, he stood there and inhaled, as if gathering the strength to move.

Sasha bit her lip, watching him with an odd mix of guilt and amusement.

"You sure you can make it home?"

Klaus let out a weak chuckle. "I have no choice. If I collapse on the way, just know... you were the cause of my demise."

"Idiot. Just get out of here before I kick your ass."

"Ah, are you trying to kill me for real?"

He received no response. Sasha had already shut the door and locked it behind him.

Maybe she was too embarrassed to keep looking at him. Honestly, he couldn't blame her. He never expected to end up in bed with Sasha of all people.

With a sigh, Klaus turned away and weakly dragged his exhausted body downstairs and out of the apartment complex. Thankfully, his own building was just across the street. The real problem, however, was the lack of an elevator.

He glanced up at the third floor, where his room awaited him.

"Of course," he muttered, clicking his tongue. "Just my luck."

Gritting his teeth, he forced himself to climb. Every step felt like an eternity as his legs protested with every movement. By the time he reached his door, he was nearly on the verge of collapsing.

Fumbling with his key, he finally managed to unlock the door and step inside.

The familiar layout of his apartment greeted him, but his attention was immediately drawn to the young woman sitting in front of his television.

She had been asleep in his bed when he left, but now she was wide awake, watching a show with interest, hugging his pillow, utterly engrossed.

Her deep purple hair cascaded down her shoulders, contrasting against her pale pink skin. Slender arms, and a slim waist gave her figure an air of elegance, but her lower body was nothing short of voluptuous— broad, shapely hips and pronounced thighs that made her silhouette all the more fascinating.

She wore his casual white T-shirt, though it hung loosely on her smaller frame, slipping off one shoulder in a way that exposed more skin than intended.

Of course, she might have looked like a normal young woman at first glance, if not for the pale pink bat-like wings protruding from her back and the matching bat ears atop her head.

Naturally, she was Briar, the summoned succubus.

She was so immersed in what she was watching that she hadn't even noticed his arrival. But as Klaus stepped further inside, he noticed something strange.

Huh? What is that?

He tilted his head, staring at her backside.

It wasn't her giant ass, which was even wider than their shoulders, he was looking at, though, admittedly, it was hard to ignore, but rather the unfamiliar appendage swaying behind her.

A tail.

Long and sinuous, it emerged just above her shapely rear, tapering into a sleek, flexible length. It shared the pale pink hue of her skin, but with a subtle gradient that darkened toward the tip.

The surface was smooth and supple, with a faint sheen.

The very end split into a heart-shaped spade, its edges slightly curved, giving it a playful, mischievous appearance.

As Klaus watched, the tail flicked absentmindedly, curling and uncurling as if responding to her emotions, twitching excitedly at interesting moments on the screen.

Its movement was strangely hypnotic, a blend of grace and instinct, as if the appendage had a mind of its own.

When did that appear? It certainly wasn't there before.

Was it possible that she had been hiding her tail? According to myths and stories, succubi were shapeshifters by nature, able to alter their appearance to fit their desired image or lure in their prey. Was this just another aspect of that ability?

Klaus sighed at the thought.

Whatever the case, he was far too exhausted to care.

Now, he was certain that she truly looked like a Succubus.

"..."

As if sensing his presence, Briar slowly turned her head. She seemed surprised to see him, but quickly frowned.

"Oh, it's you."

"Ha... That's quite a greeting. I do have a name, you know."

"Hmph. I certainly don't care about you, especially after what you did before leaving me alone. I wouldn't care if you dropped dead somewhere. Why don't you drop dead right now."

"Damn. Your words are so warm and welcoming. I'm truly touched."

Klaus glanced at her tail. "By the way, when did that appear?"

"You mean this?" Briar glanced at her tail before turning back to the television. "It wasn't there before. I guess it appeared recently."

"That's strange. I thought most succubi are born with it."

"It's different for each of us. Some are born with it, others develop it later as they grow stronger or reach maturity," Briar said nonchalantly, eyes still glued to the screen.

"So, this is a sign of growth?"

"Possibly. Even when I became an adult, I still didn't have a tail. I was rather sensitive about it, you know, and was even made fun of and pitied by other succubi. But who knew all it took was to get my ass fucked by some douchebag. That hateful man is a real jerk, if you get my gist."

I see. So she's still angry about that? I guess that is understandable. Klaus thought with a tired smile.

He could come up with plenty of excuses and say that everything he did was to save her from the soul contract curse, but what good would that do? Words alone wouldn't change anything.

If they were going to coexist, he needed to build some kind of trust with this demoness. There was no way to send her back where she came from, and their souls were bound by contract. Like it or not, they were stuck together for better or worse.

At least, until they found a way to sever the contract.

I believe it's time to clear the hostile air between us.

With that thought, Klaus took a deep breath and stepped closer to Briar. She stiffened at his approach, and her golden eyes narrowed warily.

But she wasn't expecting what he did next.

Klaus dropped to his knees, pressing his forehead to the ground in a deep bow, arms stretched forward like a samurai seeking forgiveness.

And with a loud voice, he declared—

"I sincerely apologize for my misconduct! So please, have mercy on this lowly soul!"
