The Illicitous Dungeon

Styx was facing a dilemma.

He wanted to call over Dragon and his fallen angel assistant, Loreley, to notify them of when they were needed, but he had no means to contact them from his end.

The only one capable of going over to his territory in time was Aura, but she had stayed beside Styx at all times to prevent him being captured by Spider again.

"I will just have to trust in his ability to come in time…" Styx mumbled to himself while brooding before looking at the wolf-eared woman who had curled herself up on the floor of the throne room. "Aura, at least use a chair."

The Monster Lord's ears twitched before she rose her head. She looked at Styx with eyes that were still half asleep and climbed on top of him, wrapping her arms and tail around him.

"Styx, we are ready over here," Beatrice stated as she oversaw the giant construction and furnishing of monster barns.

Despite around 600 female elves, human, beastman and beastkin breeding monster almost daily, it still wasn't enough.

There were 40,000 humans of the Third Step, while he currently had 25,000 First Step monsters and 5,000 Second Step monsters. Of those First Step monsters, 5,000 of them had the strength of a weak Second Step monster, while his Second Step monsters were as powerful as a powerful high levelled Second Step ranker.

At the same time, a further 10,000 First Step monsters were miners and various gnomes for production and each had very weak combat power.

There were over a thousand residents, 400 of which were currently at the Second Step and 30 at the Third Step. Unfortunately, the base level of monsters tapered off, so a dungeon resident needed to be <Lv. 30> to breed a Second Step monster, which had a basic growth period of 92 hours, and even the Third Step residents couldn't breed Third Step monsters just yet.

What they could breed though, were still incredibly powerful Second Step monsters just as powerful as a Third Step ranker.

Much to Styx's surprise, Vivy had managed to trigger evolution when classing up into the Third Step and was currently engulfed in a cocoon of dark energies in an enclosed shelter behind her and her harem's residence.

With the recent propaganda to breed combat monsters, his forces were being supplemented by a daily average of 400 First Step monsters and 20 Second Step monsters.

There was 60 days left until the human army reached here, meaning his total forces would reach 49,000 First Step monsters and 6,200 Second Step monsters.

Finally, there were also approximately 20,000 blood crystal bees in the now mega hive. Styx was worried as the hive seemed to hit a ceiling cap on number of bees it could house and produce with just one queen. Old bees were dying as fast as new bees could be born, causing population stagnation.

There was the possibility of birthing a new queen, but each hive could only have one queen so he would first have to build a new area for a second hive and then create cordiality between the existing hive and the new one.

Even adding the dungeon residents onto the total number of forces, who were each more powerful than a similar levelled monster, it wasn't enough to bridge the gap against the army. Styx's best plan was to fight quality with quantity. If he could trade 100 First Step monsters for the life of one Third Step soldier, he wouldn't hesitate to do so.

In order to increase the speed of which monsters are produced, he decided to use the female monsters to breed more. He had always been reluctant as they were never to his tastes, but with the process automated, he didn't need to actively participate in it.

Breeding with 10,000 monsters would increase his forces by 600,000 new monsters, an enormous force which could easily contend with the human kingdom's army.

Styx inspected this series of monster barns among the rice fields, each capable of housing a couple dozen monsters across the base floor and several underground floors.

"It looks good."

Styx commended the workers, one of which was Irie. She used her magic to terraform and do many other things to make the construction process go faster. Most of these techniques were widespread through human culture and the use of mages in construction, which the beastkin, elves and dark elves were interested to learn while the beastman were only interested in using brute force.

"Your highness, I want my reward~" Irie wrapped her lither arms around Styx's neck and started passionately kissing him.

With his Avatar Creation skill at <Lv. 24>, it was as strong as a general Second Step ranker and no longer as weak as before. Whilst it was still helpless before Monster Lords, a mage class like Irie was incapable of resisting him as he captured her in his hands and invaded her mouth with his tongue.

He carried her into an unoccupied monster barn before pinning her against the wall, one of his hands reaching up her shirt and tightly grabbed onto her large breasts. He squished the supple flesh between his fingers, while her erect nipples poked into his palms.

Irie wouldn't have resisted even if she could, taking deep pleasure in being toyed with by him. She completely cooperated as he pulled down her leggings and lifted her legs up.

She was wedged between the wall and Styx's body, suspended above the ground while her legs pressed over his shoulders.

Styx took his already erect rod and pressed it into the wet folds of her vagina.

"MMMmmaahhhhh~"

Irie moaned in ecstasy as he pushed his penis up into her inner cloister. She was wet enough he slid in all the way to the entrance of her womb and tightly pressed up against the front door.

Her entire body quivered and her slick inner vaginal walls clenched tightly around his rod.

Irie bit into his shoulder as he lowered his waist before ramming it all the way back up into her cervix. Her fingers pulled at his clothes and scratched his back as she lost herself in pleasure.

Aura walked into the barn at this moment and looked at the two with interest. Her tail swayed in the air playfully as Irie was so enraptured with Styx she failed to notice the additional person.

All of a sudden, Styx stopped moving and raised his brow.

"Don't stop~ What is it?" Irie compained before rubbing the side of her face against his.

"The monsters can't be used for breeding."

"Eh, what?"

The automated breeding system for dealing with monsters had started sending back errors to the main section of his dungeon core. Of the hundred monsters currently being inseminated for breeding, every single one failed to produce the notification for breeding.

They were still getting pregnant, but only a natural pregnancy rather than a rapid monster breeding pregnancy.

"Aura, come here," Styx looked at the Monster Lord out of the corner of his eye whilst still being submerged up to the hilt inside of Irie.

"W-when did you get here?" Irie panicked upon finally noticing Aura, her vaginal walls clamping around Styx in panic and leading to him ejaculating inside of her and causing her to moan. "OOoooahhhhh~"

Rather than choosing a monster to impregnate the magus with, he simply closed the notification and ignored it. He merely let his dungeon seed swirl in her womb and overflow from her vagina as he extracted his penis.

Aura stood beside Styx and let him pull her face over before kissing her.

Irie was let down and leaned against the wall in pleasure while rubbing her abdomen. Aura quickly bent over and took Styx's still erect meat stick into her mouth, causing him to hiss in surprise as her tongue singed it whilst cleaning off the remaining dungeon seed.

As she stood back up while licking her lips in a way that could only be seen as seductive, Styx lifted up her skirt and dropped her specially crafted panties down her legs.

He stuck his penis in between her thighs whilst standing and rubbed it up and down her pink slit.

She licked her lips whilst her lower ones were drooling all on their own, eager to receive Styx's thick rod.

He teased the entrance of her vagina with the head of his penis countless times, threatening to penetrate inside, before slipping away from that tight entrance. The wolf-eared woman could no longer take it as her tail tightly wrapped around him and arms held him in a crushing embrace.

She toppled Styx over onto his back and sat atop him, carefully and gently holding his penis upright before plunging her vagina down on top of it. With Styx's stronger body, she had clearly shown less restraint as he groaned in pain as the ground below cracked from the force of her hips against his.

Styx moaned as his rod pushed through her constricting entrance and was buried in her scorching hot inner depths. He pulled up her shirt and sucked on her nipples as she slid herself up and down his rod, hungry for its seed.

"Aura, I want you to not swallow it," Styx said while holding her thighs.

"…" She was clearly reluctant, but he told her to only hold off for a while.

Aura's vaginal lips were pushed wide open as she forced her hips to press against Styx's. She bit her lip and showed an incredible determination in restraining herself as he filled her womb up with his seed.

Her vaginal walls begun twitching slightly but there was still no notification for breeding.

"You can… swallow now."

Aura exhaled while her vaginal walls clamped around his penis and wrung out any remaining fluid. He panicked briefly as she almost seemed determined to eat his rod too with her ever-hungry womb.

Styx then inspected Irie's body and could locate his dungeon seed impregnating her not with a monster, but a baby magus.

This confirmed two of Styx's thoughts.

Firstly, there was an inherent difference between monsters and exotic races. He couldn't impregnate a monster the same as he could an elf, human, or beastman. This had nothing to do with bodily function as humanoid monsters and Aura in a beastkin form also couldn't be used.

Second, his dungeon seed was a universal type of semen, much like stem cells. This enabled him to not only breed innumerable kinds of monsters, but also impregnate monsters or exotic races in a natural way.

"Your highness! Please!" Irie desperately clung to him the following day, her face twisted in pure grievance.

"No. You are pregnant, so your womb is already occupied. Wait until you give birth then you can do breeding again."

Beatrice looked at Irie in pure envy, her expression dark ever since she heard the human, now a magus, got pregnant but she herself was denied the chance. Styx had told her to wait until after the battle with the human kingdom, as one womb out of commission was already detrimental enough.

At the same time, not being able to use the monsters as breeding partners was a significant blow to his plans.

"What are we going to do about the monsters?" Therina asked out of curiosity whilst eating a bunch of fruits that looked like grapes but were blue in color.

"The weaker ones have faster breeding cycles. There will be some issues with controlling them, but we can use them to inflate the army numbers. As for the rest, we will have to use the wild monsters. There are billions of monsters in this seemingly endless forest, we just need to trigger small groups to attack the human army."

"How?"

"I am still working on it. The easiest way is to have Aura control them out of fear. We could also bait them. It is best to trigger hive type monsters for the latter."

Irie sat at the end of the table aggrieved, only nibbling away at portions of food.
