Mating Instincts

Beatrice was petrified on Styx's lap, his member still fully submerged within her. Styx felt another wave of ecstasy as her vaginal walls tightened around his penis in a stranglehold as her entire body tensed.

He looked up at Spider who was staring in a way that could only be with an irresistible desire and smirked internally.

"I have decided upon your name," Styx said as his mana tendrils extended towards the spider giantess leaning over the back of the seat.

"Name?"

"Yes. You're name from now on is Everest, not Spider."

"Why?"

Styx's mana threads caressed over her smooth skin, gradually pushing their way into her body which she didn't offer up any resistance towards.

"Because it suits you. You are bigger than everyone else, and you are as white as snow. It's a name that perfectly suits you."

"Everest… Everest, Everest… Everest…"

Spider mumbled her new name multiple times whilst tilting her head and falling into thought. She eventually seemed to simply accept the name and throw any thought of it out of mind before leaning down towards Styx and Beatrice, who was doing her best to keep a neutral expression on her face.

Styx lifted Beatrice off his lap, who quickly pulled her underwear and skirt up before standing to the side like a professional personal assistant. It could be seen that she was standing with her thighs pressed together to prevent any leakage of Styx's seed from leaving her though.

He manipulated the floor of the dungeon and raised it until he was standing face to face with Everest. The Monster Lord leaned her face closer and stared at Styx, who reached out with his hands and cupped her face with them before planting his lips over hers.

The spider Monster Lord had little reaction, but she followed along with Styx's actions and even parted her lips, allowing his tongue to roam inside of her mouth.

Styx was surprised that it wasn't incredibly hot inside of her mouth like Aura's. There was a certain trait of heat, but it carried more of a refreshing coolness. She had a certain skill with her tongue though. As her possessiveness became stronger and stronger, her tongue was like a prey in wait, suddenly striking out and capturing Styx's.

Everest's crimson eyes faintly glowed as she stared deeply into Styx's eyes without blinking. Her arms slowly crept around his body before capturing him in her embrace with a crushing grip.

With his mana threads still filling up her seemingly endless mana network and giving her a sense of intimacy that the Monster Lord never wanted to go away, he forcefully separated his mouth from hers. Everest's tongue extended out of her mouth and slowly licked his face, an action he would never have expected of a spider.

"Do you want babies, just like Beatrice?"

Styx quietly whispered to the Monster Lord as his mana threads tried to push through the final barricade she had set up in her mind.

Babies seemed to be a trigger word for the spider monster in human form.

Everest begun hyperventilating and stared at Styx in an insatiable hunger.

"Babies… babies… children…"

"Yes, children."

"…Give them to me." Everest's voice was icy cold and threads extended through space and preventing Styx from moving.

"M-miss Everest!" Beatrice called out in panic and protest, ignoring the mess that formed on her inner thighs as she tried to get closer without being cut into pieces by razor sharp invisible space threads. "Please control yourself! You are going to harm husband!"

Styx could feel his bones creaking as they threatened to break. His avatar had the body of a Second Step ranker so it was by no means weak, but it was currently like a twig in the arms of the overzealous and crazed Monster Lord.

Everest didn't deliberately ignore Beatrice, but her attention was so solely focused on Styx she didn't even register the dark phenelf's words.

Beatrice used her incredibly vitality and golden flames to heal herself as threads cut deeply into her body before she even realized they were there. She was desperately trying to get closer and although she knew this was only an avatar, she didn't want to see her husband harmed.

"Beatrice, stand back," Styx's words quietened and halted the bloody dark phenelf in her tracks, who could now only watch in distress as Everest revealed rows of jagged teeth that could tear limbs of a fellow Monster Lord, let alone Styx.

"Everest, let me in."

"Children!"

Styx pressed up against the iron wall that was in her mind whilst repeating, "Then let me into your mind! Open up your core and fully surrender to me!"

The Monster Lord didn't show any changes externally, but the barrier within her mind suddenly turned soft and began to open up. Styx had originally thought it was a solid wall in her mind, but it was instead countless tiny threads interwoven into the ironclad barrier.

As it loosened up, her mind reached out all on its own and latched onto Styx's mana tendrils before forcefully pulling them into her mind.

What came next was Styx implanting a piece of himself within her deepest recesses of the mind, a permanent bond forming between the two of them. What was interesting was how her mind immediately wrapped around it and safeguarded it within herself, something Styx never thought possible before.

"Children…"

Everest's tone was thickly laced with desire and she was drooling out the corner of her mouth. Droplets of her saliva fell to the ground in front of Styx and caused smoke to rise as the earth was corroded, prompting him to quickly stop her from kissing him again.

"Come with me."

⠀

Styx led Everest to the home of him and his dungeon wives, where he intended for her to stay from now on too, but would need to recreate the house to be much more spacious to do so.

Outside, among the fields of flowers, Styx created a giant bed form breeders, their tentacles writhing and crawling between the oversized flowers.

Everest lay on her back in agitation as Styx undressed her. She wasn't worried about exposing her naked body, but was having an extremely difficult time restraining herself to wait for children.

Aura wasn't here, so the present Monster Lord thought this was a perfect chance to create new children.

Everest's grudge against Aura for eating her children a long time ago was rooted deep within her bones, whilst the latter hated the former for her constant aggression and attacks, so the two would never get along.

Styx didn't mind that so long as they listened to him.

On her back, Everest's giant breads defied gravity as she fixatedly stared at Styx with the occasional mention of children under her bated breath.

Her legs were shamelessly spread wide open, the lips of her pink slit also faintly separating and alluding to the hidden fruit within. A faint sheen could already be seen covering her bulbous vaginal lips and even her inner thighs, her human body reacting instinctively to going in heat.

Off to the side, Beatrice sat alongside Irie, the former casually talking about children, but her overwhelmingly powerful ecstatic emotions spread over to Styx via their connection and secretly informed him of how deeply she cared for this matter.

Styx shamelessly threw off his clothes whilst controlling the tentacles of the makeshift bed to wrap around the Monster Lord's limbs and body.

With his own engorged rod, he aimed the tip at the base of her vagina where her cave entrance was. Being so large, Everest's genitals where also much larger than normal, but Styx still had to force his way in the entrance before sliding straight inside of her.

"Hssssssssss~" Everest released a hiss from deep within her that rattled Styx's and the other girls' ears.

Despite his tentacles wrapping around her limbs, he couldn't control her movements as her long, meaty legs curled around his rear and locking him deep within her. Her vaginal walls wrapped around and sucked on his penis, threatening to tear it off should he not ejaculate within her.

Styx bit his lip in agony, but despite how painful it was, there was a deep seated sense of pleasure of being inside of her that made him refuse to pull it out.

He placed his hands on her slender stomach and supported himself, withdrawing his hips before powerfully thrusting his hips into hers, scrubbing at the walls of her cervix with his penis and causing the Monster Lord to writhe in ecstasy.

Everest looked down at him, her eyes glowing like hot coals in the night. Her mouth was wide open and revealed all her fangs, breaking up her otherwise heavenly beauty that could entrap any man.

Styx felt the danger she was exuding even more than Beatrice and Irie whom had hurried over and telling Everest to calm down.

The Monster Lord was barely holding on and Styx could tell she wouldn't last long. He controlled his tentacles to wrap around her neck and body even tighter, another one even pushing its way into her anus, but more so out of Styx's perversion.

He rapidly thrust into the giantess with wet slapping sounds, her tight vagina clamping tighter and tighter around him as her fingers turning into claws and scratching his back, drawing blood.

"Children… Children!"

"Then accept my seed!"

Styx grabbed onto the giant woman and thrust his hips as far as he could, his penis shooting out copious amounts of his dungeon seed into the Monster Lord's cervix before pouring into her womb.

The phallic tentacle inside of her anus also pushed deeper and release more seed in her back door, filling two holes at once.

"Yiyiyiy~"

Everest cried and hissed at the same time, her claw like hands grabbing piles of tentacles and tearing them apart effortlessly.

Styx winced and lied face down on her stomach, his penis still throbbing inside the warmth of her vaginal tunnel. He still recognized as the Monster Lord bore her teeth at him, her hands poised to capture him in their grip.

"Damned spider! I will bring you food!"

Styx had half expected it but couldn't control himself. His desire to mate with her was already greater than his common sense and basic survival instincts, but it wasn't like he didn't have countermeasures.

Tentacles blocked the route between him and her mouth just before she begun devouring.

"Control yourself!"

Styx spoke directly into her mind this time, upon which she released her grip on him with her legs, but still devoured the tentacles and breeders.

"Husband!"

"Your Highness!"

Beatrice and Irie quickly grabbed Styx and retreated away from the devouring spider, who was now on all fours with dungeon seed leaking from between her legs.

"I knew it was a bad idea, you shouldn't have bred with her…"

"I agree…"

Styx shook his head and spoke magnanimously.

"Some things I must do despite the danger."

Beatrice and Irie had helpless expressions and were wrought with worry.
