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

"This whole ice volcano is for us! Big sister reserved it for the whole week!" A lady with blue hair and a business suit grinned as she gestured at the great volcano.

The little elves lifted their heads and stared at the vast mountain with twinkling eyes.

A winter cap wrapped their heads. It was a custom so that the cloth would also cover their ears. Their bodies were covered by fur coats and warm pants tightly wrapped around their legs... Naturally, the elves stomped in cozy boots.

They didn't like such clothes, but no one dared to take them off in the winter environment. One brave little elf took it before, and he got punished by the cold wind!

No little elf wanted to endure the same punishment.

A vast mountain was naturally the ice volcano. Thick snow surrounded its peak, and only the bravest birds flew up and down off it. An extensive route decorated the natural environment, while the peak had a few houses reserved for the esteemed guests.

It was one of the best ice volcanoes.

"If you take a liking to it, big sister will make sure to prolong the reservation," Julia was that big sister.

"Thank you, big sister!" Little elves raised their hands and thanked her.

"Before we go, we all should wait for a special event. That event is just around the corner... Ah, look at the sky," Big sister pointed at the volcano's peak.

Ice Volcano spat out snowy balls. Those balls took to the sky, then burst into a myriad of snowflakes.

Those snowflakes surrounded the whole volcano and beyond.

"Seriously," Minato's lips parted as he stared at the falling snowflakes.

Yuna and Bei chuckled around him.

The elves also enjoyed the atmosphere together with their kids.

Ingrid urged everyone to not stare for too long, though, "If we move now, we will climb up the ice volcano amidst the snowflakes. Doesn't that sound nice?"

"It does, queen!" And so little companions marched forth.

A few wild animals and beasts stared at the newcomers. Their eyes widened upon looking at the elves. Even though these beasts were stronger, they still wanted to serve the elves and fulfill their wishes.

Thus, some little elves snitched those beasts to their forest...

Minato rolled his eyes, "They became quite good at it."

Bei said, "Won't these beasts die without an ice dungeon in your world?"

"I hope not," Minato scratched his hair.

The peak of the ice volcano possessed ice pools.

The Majestic Ice Kingdom would profit from these pools as they increased the ice resistance for anyone who bathed here. It was a challenging task, though! 

Naturally, the royalties were prepared for it, and they had a lot of stuff that would help people deal with coldness and adapt faster.

That stuff was free for all elves and Minato.

The residents from the capital also had the means to make the cold bath enjoyable.

Big sister smiled, "Don't fear it, little ones. This bath is healthy, and we all want to live long enough to see our Master's glory, don't we?"

All little elves nodded.

The elves behind the elven queen nodded together with her.

"We want to become stronger and help Master!" Little elves resolved their will.

They all took off their clothes to enter the bath...

Behind them, Minato stared at everyone with a faint smile. He felt like tears soon would swarm his eyes as he never had that many people supporting him.

His time in the Orphanage was rough, and he was alone to fend to himself after turning eighteen! Now, he had gorgeous women in his family and many people wanting to become stronger together with him.

He smiled widely, "Let's enter it, guys."

Minato took his clothes as well, but he kept his briefs on. The adult elves did the same!

They all entered the cold bath.

"It's not really cold!" Little elves exclaimed, then they began casually swimming throughout the cold lake.

However, were it not for Julia's magic circles, the whole bath would've been different for them.

Out of all the people here, Minato, Bei, and Yuna were the only ones who faced the iciness with their bare bodies.

It wasn't a regular bath, though.

That ice volcano was reserved for people with high backgrounds. Effects were much higher than in other volcanoes, and the scenery was also on a different level.

Minato enjoyed the bath.

Yuna was on his right while Bei took the other side.

Julia was also a good guide and 'princess maid' as she often brought some fruits to him. Their current menu was just fruits since that was what elves mostly ate.

Bei and Yuna would feed Minato in turns, and he would do the same to them.

Ingrid also would find some time with him...

And all elven women that had time with Minato also would get some attention from him. When Bei and Yuna went to look after little elves, Minato spent time with the elven women.

They talked and fed themselves with fruits while building anticipation for the scheduled night.

"Now... I just hope no one will suddenly come out... Overlord Enemies? My world Enemies? Let me relax a little..." Minato buried most of his body in the cold water while leaning down on Ingrid's voluptuous body.

He laid his head on her breast pillows as chilled in the water...

Ice Volcano shook a few minutes later...

Minato's eyes opened, "Did I jinx it?"

He called all elves to his side, then brought them back to his world.

Minato lifted his body and stood in the bath with Ingrid by his side. His beloved soon came to his side, and all of them wondered about the ice volcano's trembling.

Minato shifted his eyes to Julia, "It was not a normal reaction, was it?"

He called back everyone solely because of Julia's flustered expression.

She approached him in her swimsuit and replied, "I have never felt such tremors... This is troubling..."

"This can not be a coincidence... Someone is welcoming me, right?" Minato smiled.
