Unrivaled Demon's Odyssey

Nero was lying naked on the bed with his eyes closed, and Asteria was sitting beside him— naked, with a dagger in her hand.

Asteria raised the dagger and glanced at Nero before plunging it deep into his chest.

Nero opened his eyes and shook his head as if he couldn't comprehend the situation.

He looked into Asteria's eyes and slowly opened his mouth to say, "You suck at this."

Asteria curled her hips and said, "It's hard for me."

She crushed the dagger in her grip, and it disappeared soon after shattering into pieces.

The spot where Asteria stabbed Nero was unscathed because the dagger never pierced him, and Asteria released the magic before it could touch Nero.

Nero smiled at Asteria and sat up, saying, "Nothing would have happened to me even if you had stabbed me, you know?"

Asteria squinted her eyes and asked, "Would you have stabbed me if I said the same thing to you?"

"Well…" Nero couldn't say anything, or rather he didn't have anything to say.

"You got me there."

After a while, Nero chuckled, thinking, 'Emilia and Sophia are gone.'

As expected, Nero was aware that Emilia and Sophia were peeking, and he could feel a sudden influx of powers around him when they saw Asteria stabbing him with the dagger.

'I have never seen Emilia that scary before…' Nero had seen all the sides of Sophia as he had lived more than half of his life with her. But he didn't know many sides of Emilia, except her pervy nature.

Nero smiled at Asteria and said, "Leto asked me to teach you everything, so I will teach you how to kill too."

"I know how to kill. I know all the ancient spells and magics. I also know some arts." After a brief pause, she said, "I am more powerful than I seem."

"I know. You possess skills and abilities even I don't know. Although they are just variants of different types of magic I knew, so it wouldn't be hard for me to learn them after seeing them once, or at most twice."

"So why did you ask me to stab you?" Asteria asked, still unknown to the reason why Nero asked her to do something so blasphemous.

"There is a difference between having the power to kill and killing. I don't doubt your power to kill anyone, but can you truly kill anyone?"

Nero waited for Asteria's answer but added, "Or have you ever killed anyone yet?"

Asteria shook her head.

"What about animals or monsters? Have you killed them? I know you were locked in the tower all your life, but still…" Nero asked as he raised his brows, "Have you?"

"No," Asteria replied meekly.

"See? You don't have the ambition to kill, and one must have that to survive in this cruel world. There would be many situations where there would be a kill or be killed situation. And there, you won't have the liberty to be kind."

Asteria puffed her cheeks and muttered, "I thought this night was supposed to be our fun night."

Nero choked on his words and sighed as he realized he went too far by giving her an off-topic speech during their special first night.

Nero hugged Asteria and carried her in his arms as he stood up from the bed.

"What are you—"

Before Asteria could ask what Nero was trying to do, Nero tossed the bloodstained blanket down the bed, threw Asteria on the bed, and then jumped on top of her.

"Are you ready for our third round?" Nero asked with a grin on his face and kissed Asteria.

"Yes."

"Are you sure? Because that's what you said in our second round and then started screaming because of the pain." Nero teased with a smirk.

After some foreplay during their first round, Asteria couldn't bear the pain and started moving when Nero was still halfway in, and because of that, the blood spritzed around the blanket.

Asteria claimed that she was ready for the pain, but she never expected it to be this extreme. She had never touched herself or even masturbated in her life, she had no experience in such things, and she got confused between pain and pleasure.

"You keep teasing me like that," Asteria murmured.

"Do you not like it?"

"It's not that I don't like it. But I  can't say anything in return because everything you say is always true."

Nero kissed Asteria again and said, "I will be extra gentle this time, and if it still hurts after that, we still stop and start a new the next day, alright?"

"I am fine now, and it felt good during our second round after a while."

"Well, then. Here I go."

Asteria closed her eyes and prepared herself to get penetrated. After a while, she opened one eye to peek and found Nero grinning at her.

She bit her lips and said with teary eyes, "You are teasing me again."

"I am already in."

"Huh? But I don't feel any— anh~!"

Nero thrust his body which caused Asteria to moan in pleasure.

"Now that was a cute moan," Nero remarked.

Asteria pouted and pulled Nero close to her face by wrapping her arms around his neck and kissed them before saying, "Stop teasing me."

Nero kissed Asteria back and began thrusting as he increased his speed little by little. 

As time passed, Asteria's moans turned louder and louder as she felt better and better. She moved her hands from Nero's neck and scratched his back with her nails.

"I am— Anh~ !" she tried to apologize but ended up letting out another moan.

"Don't worry about it. Emilia scratches me all the time."

The only girl Nero was always rough with was Emilia, and in return, he got scratches all over his back, neck, and chest.

As Nero was thrusting, he noticed Asteria's face was growing more and more red. 

Asteria everted her face to the other side, saying, "Please don't stare at me like that."

Nero chucked and uttered, "You are just like Leto."

Asteria looked into Nero's eyes with her eyes full of curiosity, as though she was dying to ask something.

"What is it?" Nero asked.

She shook her head and said, "It's— Aanh! It's nothing."

Nero raised his brows and threatened, "If you don't say, then I will stop thrusting."

"Please don't stop!" Asteria yelled and then said in a low voice, "I will say it, so don't stop."

After catching her breath, Astrea quietly spoke, "You married Ma, right?"

"Umm… kind of, yeah. You can say that since I gave her my name and called her my Queen."

"So… you are also my Pa now, right?"

Nero stopped thrusting after the sudden realization as though that thought had never crossed his mind.

Nero's mind was occupied with different things over the past few days. First, he never planned the war with Norox, and he had no idea about Ajax's descendants.

After saving them, he was busy stabilizing his body so it wouldn't corrupt his cores like it did when he transformed during Laira's revenge.

Then, when he killed Darius, he found one of his cores, which made him question his other cores, which were far worse than the Sin of Greed.

During all this time, he was most worried about Asteria and her being a reincarnation of princess Astrea.

"Why did you stop?" Asteria wrapped her legs around Nero and began thrusting them up and down.
