My wife's sisters want me to make a harem?!

Minato's visit wasn't a surprise to any Volcano Lizard.

They were the race who wielded runes the best, and their volcanoes matched many blacksmiths from the middle worlds. Their skills helped them engrave runes onto items and do many wonders.

Minato was pleased with all their services, including the dual cultivation sessions.

Followed by Bei, who had already contacted those Volcano Lizards, Minato stepped into Veronica's room and took the seat.

"You know what I want. Any ideas?" Minato lifted the hot cup, drinking the unique warm drink.

Bei was on his right, smiling at Veronica.

Reciprocating that smile, Veronica glanced at the couple and said her idea, "If Master wants to leave teams equipped with your mana, we can add steel layers to their armors. Let's say that the Hard Steel Empire's armor consists of one layer.

It will be its base.

We will test how many layers with Master's mana we can add, then the forces will be naturally equipped with your mana. If push comes to shove, they will be able to utilize your mana to increase their defenses," Veronica concluded.

The reasoning was simple.

Minato would fuel the volcano with his mana, allowing volcano lizards to create countless armor with diamond defenses. His mana would reside in the armors, hidden from all experts' eyes.

The Overlord's Mana was so unique that it was easily achievable. Just it alone residing in many items would give them high defenses.

Of course, Veronica and her race had already taken over the empire's method, so they would use it to hide mana and make enough preparations for all leaving teams.

"If Bei uses her magic circle and helps us fuel the volcano, we will thoroughly hide Master's mana and increase the forging process," Veronica smiled widely.

Minato raised his eyebrow at how she casually called Bei's name.

But since Bei didn't show any reaction, he retracted his eyes and asked, "We will need jewelry for mana boost and some weapons too."

Veronica nodded, "Jewelry should be easy... As for weapons, it's not our forte. We will try our best, though."

"Good. What do you think, Bei?" Minato asked his beloved.

Resting her head on her hand, Bei turned her eyes to Minato and replied with the usual lofty smile, "We will be locked in one room for some time."

"I don't mind," Minato stood up and replied, "Let's head straight to the volcano, then."

-

Although it would be good if all volcano lizards worked on the new projects, Minato requested only women he has been dual cultivating with.

That was because dual cultivation wasn't just about one's strength benefits. During an exchange of liquids, Minato regenerated his mana faster.

His world already increased mana's regeneration and boosted countless treasures and bodies with it. Still, if he dual cultivated here, then the effects doubled!

That was precisely why Minato basically gathered his harem of Volcano Lizards to the main volcano.

Bei stood out here the most.

All volcano lizards had red hairs. Like the frost dwarves, the ladies had different shades, but all remained red. One would see some women with near pinkish colors, which made their bodies cuter and quite innocent.

Veronica, for example, had red hair like blood, and it suited her curves and expression, which were sharp and tempting.

Bei was much closer to Veronica with her curves and mood.

She spread her arms and conjured a wide area magic circle, which swallowed the whole volcano.

Her lips curved into a victorious smile, "I extended my attention toward the barren land and gathered mana from here. This is another boost this princess brought to you, Minato."

As she said his name, Bei sweetly smiled.

Minato brought her closer to himself, then yanked off her clothes, revealing her bare tits, "We will dual cultivate now."

"Your sexy assistant will show off those lizards what dual cultivation is," Bei replied with confidence, joining her hands and pushing out her tits with her arms in the process.

Those two soft peaks begged for attention as Bei's movement puffed them.

Minato promptly grabbed these, fondled and roughly kissed them, "I missed this taste too much."

"Did you?" Bei tilted her head slowly, eyeing Minato as he sucked on her nipples, "I thought about you during every break... At night, I fingered myself thinking about your vulgar tongue and big cock.

I will tell you a little secret... The elder sister was the same," Bei winked, making her beloved suckle on her nipples with even more sucking force!

And while he did, his magic circles box continued to fuel resources required for armor forging.

Naked Volcano Lizard women shook their bottoms charmingly as they moved back and forth, putting those resources into the box, which acted like the furnace.

"Ah... I came..." Bei whispered with her seductive tune.

Minato smiled victoriously, then yanked her panties down a little. Her beautiful and meaty ass promptly came out. Those two cheeks tightly landed in Minato's greedy touch, his hands kneading each tightly.

He lifted his beloved and impaled her drenched pussy with the big cock Bei dreamed of back in the high world.

Minato smirked, "High World has so many treasures, yet you dreamed of a lowly Overlord whose strength can't even peak in the medium world."

Holding his shoulder tightly, Bei cast an arousing side-glance with her moon eyes shining brightly, "You've tamed Beibei too good."

"Oh, you little," Minato roughly replied, sliding down Bei on his big cock.

As he filled her pussy with that thick meat, Minato groaned alongside Bei. Both of them hugged and joined their lips in a sultry kiss while their lower bodies desperately rubbed each other.

Doing it while standing was always a challenge, so kissing sounds prevailed in the hot volcano. However, Minato was well versed in doing it in many ways, so he wouldn't give up until his seeds filled Bei and permeated her womb.

In slow but strong and jolting thrusts, Minato stretched Bei's insides while his fingers sank deeply into her bottom.

At the same time, Volcano Lizards patiently worked on the whole process, peeking at the lewd duo who were quite advanced in dual cultivation.
