Nero was sitting comfortably on the bed in a relaxed position. Emilia was lying with her head resting on Nero's lap. Sophia was sitting beside Nero on the right side with her head resting on Nero's shoulder, and Asteria was seated on the left with her head resting on Nero's other shoulder.

Nero was playing with Emilia's hair, and Emilia was enjoying Nero's warmth by burying her face between Nero's thighs.

"Stop doing that," Nero uttered.

"But it feels good," Emilia replied.

Emilia started playing with Nero's tail and got engrossed in it.

"You ate too much today," Sophia remarked.

"I did?" Nero wondered with a puzzled look on his face, as though he wasn't aware of it.

"Yeah." Asteria nodded and replied, "Did you like the food that much?"

"The food was certainly delicious, but it can't beat you girls cooking." Nero landed a smooth line without realizing it.

"I used my powers, so maybe that's why I was feeling hungry," Nero stated.

"What powers?" Sophia asked curiously.

"I am not sure, but I think it was void powers," Nero replied.

"Hmm~" Sophia hummed in wonder.

Nero moved his hands towards Sophia and Asteria's sacred place and fingered them. Emilia, however, was busy playing with Nero's tail.

Nero glanced back and forth at Sophia and Asteria and said with a smirk on his face: "Let's do it."

Sophia squinted her eyes and muttered, "You know, you are getting horny all the time."

"Is that… a new thing?" Nero asked with a surprised look on his face.

"Yes! To me, it seems like your libido has drastically increased," Sophia remarked.

"But…" Asteria turned to Sophia and uttered, "Isn't that a good thing?"

"It is, but… umm..." Sophia struggled to find the right word. 

After pondering for a while, she said, "You are acting like Emilia."

"What is… that supposed to mean?" Nero wondered with a puzzled look on his face.

"A pervert!"

After hearing the word pervert, Emilia sat up and looked at Nero and the girls. Then, her gaze fell on Nero's hands that were fingering Sophia and Asteria.

She frowned her face and asked, "What is going on?"

"Just some foreplay before the main event," Nero replied nonchalantly.

"Without me?"

Nero smirked and uttered with a smug look on his face: "You were busy with something else, and you looked like you were having fun, so I didn't disturb you."

Emilia made a face like an abandoned puppy with teary eyes and stared at Nero.

"You know that face doesn't work on me," Nero scoffed.

Emilia frowned her face and jumped on Nero: "So what?"

She pulled his pants and uttered, "I can just do this… and that!"

Two hours passed, and the three girls were satisfied. They had an orgasmic look with slutty smiles on their faces. However, Nero wasn't satisfied.

Nero turned to Asteria, but she shook her head and said, "I am done for now."

He turned to Sophia, and she said, "No more."

Then, he turned to Emilia, knowing she wouldn't deny him, but she averted her face and said, "I need a break."

"You girls are getting tired quickly," Nero commented.

"It's not us; your libido has increased," Emilia retorted.

"That's right," Sophia nodded. "You are turning into Emilia."

"I am not a pervert like Emilia," Nero remarked.

"I am not a pervert either," Emilia quipped.

After pondering for a while, Nero uttered, "Has my libido truly increased?"

Asteria and Sophia pointed their gazes at Emilia and said, "Even Emilia— who is the thirstiest pervert, feeling satisfied, then yes. Your libido has increased."

Nero had realized that. He was aware that the stronger he got, the deeper his curse would react. 

In the past month, Nero had retrieved three of his weapons and one core that boosted his power but also made the curse more stronger. 

Nero could control himself in front of others, but his libido had increased.

"Maybe I really should get one more girl? Nero murmured and looked at the girls to see their reactions.

The girls glanced at each other without saying anything.

"..."

Nero raised his brows and opened his mouth to say something, but Sophia cleared her throat and said, "As we said before, if you want to get a new girl, then go ahead. But getting a girl just for sex is… I don't know, horrible, maybe?"

"Then how about I buy a slave?" Nero wondered.

"A sex slave? That's more horrible,"  Emilia remarked.

"I will do it with their consent, of course," Nero stated. "You know I am not into other disgusting techniques."

Nero laid between the soft bodies of the girls and yawned.

"Does slavery still exist, though?" Sophia windered with a curious look on her face.

"Well, there are two types of slavery," Asteria answered. "One is legal slavery, in which the slaves sell themselves for money in order to get a new home and a better life. While the other one is illegal slavery, which happens in the black market where the abducted slaves are sold in the auction, and the one with the highest bid buy them."

"That's horrible," Emilia uttered in a disdainful tone.

"Every world is a terrible place for the weak and poor," Nero asserted with a distant look on his face.

"So, are you truly going to buy a slave?" Asteria asked.

"A legal one, yes. And I would only do it with their consent," Nero replied honestly.

"What type of girl would you go for?" Emilia asked.

"I am not sure. But if possible, then I will go with monster girls."

"..." Emilia and Sophia looked at Nero in disbelief.

"What? Why are you two looking at me like that? Monster girls are great, you know? You can have extra benefits during sex, and they can last longer. They also have high endurance, and they must feel awesome.":

Asteria squinted her eyes and asked with a serious look on her face: "How do you know all that? You have never been with a monster girl before, right?"

"Well… I have read books about them, you know?"

"Books on monster girls?!" Emilia exclaimed.

"Yes. There was a famous author who had written everything about monster girls, including interspecies and mixed breeds. I have been curious about them since—ah!" 

Nero blurted out his monster girl fetish in excitement.

"I knew it," Sophia muttered.

"Knew what?"

"You are turning into a pervert."

Nero closed his eyes and muttered as his voice faded away: "I guess… so."

"Zeus?" Sophia called out to Nero.

"What happened to him?" Emilia asked with a concerned and anxious look on her face.

"I think he is simply exhausted," ASteria stated.

"He has been awake for more than two weeks, after all."

"What should we do now?" Emilia pondered. "It's still early evening."

Sophia covered Nero and herself with a blanket and said, "We might be leaving tomorrow, so let's sleep early."

"Let me sleep beside Nero!" Emilia tried to get between Nero and Sophia, but Sophia didn't let her.

Sophia pushed Emilia and uttered, "Don't be so greedy! Let me sleep next to him once in a while."

Emilia quietly laid down beside Sophia and covered herself with a blanket.

'Wow. She gave up in one try.' Sophia was impressed.

Emilia smirked inwardly and uttered to herself: 'I will push her down when she falls asleep.'
