Chapter 9: The Master and the Slave’s Oath

She looked so happy, so pleased with herself. I was disgusted, and I wanted to throw up.

"Master. Quickly... quickly, let us finish this rite so I can complete my awakening."

『The submission ceremony's final phase has begun.』

『Please exchange your vows.』

"I, Eura Nanashi, take you, Yuuto Nanashi, to be my lord and master, to serve and to obey, to pleasure and to suffer, from this day forward."

"I vow to submit to your every whim, to be your plaything and your possession, in sickness and in health, in riches and in poverty, until death do us part."

"I promise to always be meek and subservient, to never question your authority, and to always do as you say, no matter how much it may hurt or degrade me.

"I will be your willing slave, your object of desire, and your source of amusement."

"I give you this ring as a symbol of my submission, and I pledge to wear it always as a reminder of my place at your feet."

"From this moment on, I am yours to use and abuse as you please, and I will take pleasure in every moment of your domination."

"This is my vow, my submission to your power, and I will never resist it. So be it."

What kind of fucked-up marriage oath is this... shit...

"Master, it's your turn." She handed me a pitch-black box.

I opened the box to see a ring. The ring is black and made of a strange, metallic material. The eye at the head is glowing red with cat-like pupils, and from the circular body of the ring, leg-like tendrils curl and spread outward, each with a sharp pointed edge.

My mouth suddenly began to move and talk on its own.

"I, [Yuuto Nanashi], take you, [Eura Nanashi], to be my partner in chaos, to love and to manipulate, to hold and to control, from this day forward."

"I vow to always put my own interests above yours, to deceive you in sickness and in health, in riches and in poverty, until death do us part."

What the hell is this...

"I promise to make you suffer and bring you to your knees, to exploit your weaknesses and revel in your pain."

Stop. You asshole. What the fuck are you doing?!

"I will be your downfall and your destruction, but you will never be able to leave me, for I will always have a hold on your heart and your soul."

Are you out of your mind!? Stop. Why can't I move my body?!

"I give you this ring as a symbol of my twisted devotion, and I pledge to use it to chain you to me for eternity. From this moment on, you are mine to do with as I please, and I will take pleasure in watching you suffer at my hands."

No. What the hell are you talking about. Put down the fucking ring!!!

"This is my vow, my twisted promise to you, and I will never break it. So be it."

She knelt at my feet, her left hand extended towards me.

She looked up at me, her eyes filled with lustful satisfaction.

My arm moved on its own.

I watched her face as my right hand took hold of the ring and placed it on her ring finger.

Once more, my body bent forward on its own. My hands glided over her shoulders.

My body kissed her.

Our lips collided together. Her tongue extended as if to explore all of me.

A soft moan escaped her mouth, mixed with the taste of her saliva.

The kiss lasted for a long time, and eventually, we broke apart.

"Thank you, master.... for giving me the liberation I've always dreamed of." Her voice trembled slightly.

"You're welcome..." I replied as my lips moved toward her neck.

『The submission ceremony is complete.』

『Congratulations! Household member "Eura Nanashi" has successfully completed the ritual.』

As soon as I regained control of my body, my muscles tensed, and I felt a powerful energy surge through me.

Before I knew it, I had shoved her back with enough force that she stumbled backward. It was only after the shock of my actions settled in that I realized what had just happened.

"I'm sorry..." I said as I tried to help her up.

"Master, please stop... teasing this slut...♡... when she's in heat." Her voice trailed off, a devious smile on her lips.

"What... shit... this must be the work of the damn system," I shook my head and sighed.

I walked towards the lined-up decapitated heads of the bandits. As I created incisions on the skull, I felt hands coiling around my body. It was Eura, and she was nibbling and licking my ear. It felt so good that I had to suppress a moan.

"Master ♡"

Her hands grabbed me firmly, and she pressed her breasts against me as if she wanted to merge with me.

Her touch was so gentle, so sweet...

"Stop. I have to eat these brains before they rot."

"But master... I'm hungry, too. Please let me eat your brain first!"

"That's pretty fucked up, Eura..."

"I... I can't help it; you are so cute, master ♡"

I finished extracting the brain and took large bites out of it. The soupy and rubbery texture made me want to puke, but I persevered, knowing there was no other choice.

As I was eating, I felt Eura's hands wandering all over my body. They were so soft and warm.

"Master, can this slut cut the next one open?"

"Are you familiar with the process?"

"Yes ♡," She replied while smiling lovingly.

I handed her the knife, and she carefully started the next harvest.

Her cuts were very quick and precise. Did she learn all that just by watching me once? What a terrifying woman...

I looked over the two brains, which were now completely devoid of their former shells.

"What do you think, master? Did I please you with my work?"

"Yeah. You're pretty good."

"Thank you, master ♡," she said while staring at me with her bright red eyes.

"It's unbelievable you were that person who was squirming while I was eating those brains."

"Are you talking about that time? It was devastating... I felt so powerless and scared. But now, with my master by my side, I feel like I can do anything! I feel like a god. I can defeat any number of those bastards. It's all thanks to master ♡"

I was amazed by her sudden change. Did the system really have that much of an effect? I could only imagine... it must have been an experience like a religious awakening.

"Master, if it pleases you, may I be rewarded for my work?"

"Yeah, sure. What kind of reward?"

Trembling with excitement, she pushed her face closer to me.

"Kiss me, master ♡"

I gave her lips a quick peck, but that didn't satisfy her, so I continued to kiss her.

"I love this, master. I think I'm going to be addicted to this ♡"

"Can I feed you, master?" she said while smiling.

"Uhh."

She stood up and took a brain from the table. Walking back towards me, she took a bite out of the organ and chewed it.

Why is she the one eating it?

She gestured to open my mouth ー and then promptly shoved the chunk of the brain into my mouth.

The brain matter was soft and squishy, with a distinct putrid flavor that was balanced out by her saliva's sweetness. The texture was almost like jelly, and it spread quickly over the tongue. There was an underlying bitterness that lingered on the tongue after swallowing.

"Master, eat more ♡"

***

After we finished eating, she stuck her tongue out and licked the rest of the juices on my lips.

『Quest Completed - Not a Bad Slime』

『Difficulty: Intermediate.』

『P-please, don't hurt me! I'm not a bad slime! If you feed me, I'll show you something slurprising..』

『Rewards』

『Achievement: Slime's Favor』

『*Slime's Favor: Permanently increases loyalty by 50 and will not decrease further.』

The sudden pain felt like being stabbed with thousands of needles all over the body. The black fluid oozed out of the eyes, mouth, nostrils, and ears like thick tar.

"Master, what's going on?"

My throat tightened as I coughed, trying to expel the substance from my body. As I finished coughing, I replied, "Stay away. I'm fine. Don't worry about me."

The black fluid has formed into a teardrop-shaped jelly with two red dots that resemble eyes.

It stared at me.

ー I stared back.

[Zzzhhhhhhhhhhhhhh]

It was trying to speak, so I listened.

[...….brain.....]

"Y-yeah, I'll feed you. Don't worry."

The slime seemed to be happy because it shuddered and frothed...

The jet-black droplet began to wobble and then moved toward my leg. From there, it climbed up toward the top of my head before reforming its droplet-shaped body.

[T-thank.....you...]

"Master, is that a slime?"

"I'll explain later. Let's go get some rest for now."

"Yes, master ♡"
