"Nemesis, your master calls upon you. Present yourself!" I command.

Instantly, the air in front of me starts to shimmer. And the next moment, a small tearing noise comes and a large crack appears in the empty space as if someone has forcibly torn up the air itself.

Hmm…I thought that that vortex-like thing will appear again. Now, what is this?

I bend down a little to see inside this crack which is hovering mid-air.

Ahh~ it's completely dark inside… wait…

Suddenly, out of this darkness, a pair of legs emerge.

"W-What is happening!? What is that!?" Arya shouts in a scared voice.

Following the legs, a whole female body wrapped in a black colored dress emerges out from the crack. One the woman lands on the floor, the crack starts to get sealed before disappearing into thin air. This whole process takes around 10 seconds to complete.

"You called… my master."

Nemesis, who just got summoned, says while kneeling in front of me. Though she is addressing me as her master, the way she is voicing it is…

"You are still angry, huh? I thought that becoming my slave will change the way you think about me as well…" I say with a shrug.

"You hold my entire existence in your hands, master. And because of that, I have to obey your every command and show you my utmost respect. Though mind, this doesn't mean that I have to actually respect you in my heart…" Nemesis says in a neutral tone.

".. And like a goddess can ever respect a filthy human like you, who forcibly enslaved her…" She spats in an undertone.

"Hahaha… Fair enough. Now, get up and follow me. We are going to have a bath together," I say.

"A bath…?" Nemesis says while looking up at my face with a frown. Till now, she was only staring at my feet.

"Yes, a bath. You won't turn down your master, will you?" I ask with an innocent smile.

"You lowly piece of— Ahem, I mean, I will do as you wish, master," she replies while gritting her teeth.

"Come on then…" I say while turning towards the stairs.

"W-Wait a second, brother!"

Suddenly, Arya grabs my arm and forces me to stop.

"W-Who is she!? How did she appear from that crack!? A-And why is she calling you her master!?" She asks while looking extremely uneasy.

Hmm… Should I tell her?

Well, we will be living together for at least the next few months. And I don't know how many times will I have to summon Nemesis in front of her. I guess it's better to tell her a few things now…

"Well, let me introduce both of you. Nemesis, this is Arya, my cute little sister. And Arya, this is Nemesis, the goddess of revenge and my eternal slave. Now, let's go to the bath…" I tell them.

""…""

Both of them stares at me in disbelief.

"Is that how you introduce a goddess to a lowly human!?" Nemesis asks angrily.

"Hmm? Is that the tone you direct towards your master?" I ask back while raising my eyebrows.

Nemesis gets silent while gritting her teeth again.

"N-Nemesis? Slave? B-Brother, are you all right? There is no way a goddess can be here. And you shouldn't call the revenge goddess your slave like that…" Arya says, looking greatly worried.

"At least, this one has some sense…" Nemesis says in a low voice.

"Nemesis, is there any way to prove that you are the real deal?" I ask.

"If master wishes for it, I can…" she replies.

"Good, do it then…"

Nemesis gets up from the kneeling position and moves towards Arya.

"W-What are you doing?" Arya asks, stepping back.

"Don't worry. She won't hurt you…" I say while grabbing her shoulders to keep her in place.

"Wait—"

Nemesis raises her left hand and touches Arya's forehead lightly. Instantly, Arya's eyes open up wide in shock and her footing becomes unsteady.

"Y-You… You really are…" she says in a frightened and shaky voice.

"What did you do to her?" I ask Nemesis with a frown.

"Nothing much. I just showed her a glimpse of my true divinity and godly powers…" Nemesis says simply.

"Brother… how did you even…" Arya asks me in a disbelieving tone.

"Let's go upstairs. I will explain it to yo on the way," I tell her with a smile.

"Brother, that was extremely dangerous! And why are you even trying to do capture goddess!?" Arya asks while looking horror-struck.

"Well, I just told you about a few things so that you can understand how Nemesis became my slave and all. The reason why me and Lucy are doing this, well, I will tell you later along with everyone else. It might take time to explain…" I say.

Arya keeps looking at me for a few seconds, clearly wanting to know everything right now.

"… fine. You can tell me later," Arya finally says with a sigh.

"By the way, I was wondering since a while ago, why is there a bulge in your towel?"

"What?" I say while looking down.

"Oh… Hahaha, don't worry, I am not erect or anything," I assure her while laughing lightly.

Right now, me, Arya, and Nemesis are inside the bathroom upstairs, with only towels covering our body. While me and Aria are completely at ease, Nemesis is standing a few feet away from us with a disgusted and angry look on her face.

"… making a goddess bath with mortals… how dare they…" she keeps repeating to herself.

But man, this is great…

This bathroom is around thrice the size of a standard one and surprised even me when I first entered it. There is even a large bathtub in the middle, which can easily accommodate upto 5 or 6 people.

"You are not erect? What do you mean by that?" Arya asks me again in confusion.

"Hmm? I meant that my penis is not erect. You see, I won't get hard just from seeing you in towels. Though I cannot guarantee it once we start bathing together…" I say while laughing again.

"Penis? What's that?" Arya asks while tilting her head.

"…"

I look at her with a frown. Even Nemesis stops her chanting to listen.

The way she asked that and how innocently she is looking at me right now, I don't think she is joking…

"You seriously don't know what a penis is?" I ask.

Arya shakes her head.

*Sigh*

And she is just a year younger than me…

"Well, it's a male reproductive and excretory organization. It basically looks like a hose. Men put it inside a woman to implant their seeds and make them pregnant with a child…" I give her the shortest and simple explanation I could.

"Hey! You could have stopped after the first line!" Nemesis says angrily.

"Ehh? Really? I thought men have this as well…" Arya says while removing her towel, and spreading her legs to show me her cute little pussy which is light pink in color and is completely hairless.

Woah…

Not just her pussy, her bare tits also looks amazing. They are big and have an amazing shape. Her slender stomach and waist are also really sexy and completes her hourglass figure along with her round ass.

Though I would like to see her once all this blood and dirt is removed from her body.

"Hey! Why the fuck did you strip down!? And why are you spreading your legs!?" Nemesis shouts in disbelief.

"Well, you are really beautiful, sis. Let me return the favor as well," I say while dropping my towel and revealing my limp, yet huge member to her.

"Hey! What the fuck are you—"

Nemesis starts to admonish me but then, her eyes get stuck to my cock, forcing her to stop in the middle of the sentence.

"Wow! I never thought that something this big is between a man's legs…" Arya says in awe.

"No, normal men don't have it this big even when they are fully erect. He is just a monster…" Nemesis tells her while still continuing to stare at my cock.

"Brother is special… Amazing… Can I touch it?" she asks me excitedly.

"Sure. It will get even bigger if you do so," I tell her with a wink.

"Really? I want to see it get bigger! In return, I will also let you touch me between my legs!" Arya says while jumping happily.

"Well, it's a deal then. Go ahead…" I say while presenting my cock.

Arya doesn't get shy at all and instantly grabs the shaft of my cock.

"Woah! It twitched!" she says excitedly.

"And it's so thick… I cannot even wrap my hand around it…" she adds in awe.

"Can I touch you between your legs as well?" I ask.

"Feel free!" Arya replies while spreading her legs again.

Fufufu… Such a cute little sister I have…

I move my hands towards her pussy…

"STOP!" Nemesis shrieks.

"Just stop both of you! What the heck are you doing!?"

Her cheeks are blushing a little, but her expressions are extremely furious.

"I am having fun with my younger sister, can't you see?" I ask her while raising my eyebrows.

"Fun? FUN!? You both are just— Ahhhgh! I cannot even tell you off. Anyway, what about cleaning all this blood you are covered with!? And didn't you mention that you need to get to the guild fast!?" she says.

"Well, we do have some time in our hand…" I say with a shrug.

Though Arya has already removed her hand from my cock.

"Brother, I think Nemesis is right. We need to hurry. We can touch each other some other day…" she says with a smile.

Sigh… And it was just getting good.

But well, I guess it will be better if we have some extra time in hand, just to be precautious of any unexpected situations.

"Sure, we will continue this some other time. Well then, go and clean all the blood and dirt off of yourself. I want to talk with nemesis a little," I tell Arya.

She gives me a nod before moving to the other side of the bathroom and beginning to wash herself.

"Nemesis, remove that towel and start cleaning my body," I command her.

"You… You are asking a goddess to clean your body!?" Nemesis asks, looking outraged.

"No, I am asking my slave to clean my body. You got any problem with that?" I ask.

"And by the way, I noticed that you have stopped calling me master."

"I-I am sorry… master," she apologizes while gritting her teeth.

"No problem. Now, do as I say…"

While giving me a hateful glare, Nemesis drops her towel and reveals her naked figure to me. Even though her curves are moderate, they go along extremely well with her body type.

Then, she brings a bucket filled warm water closer to me and begins to wash my body with her soft hands while pouring water slowly.

I thought that Nemesis will try to hurt me with her nails or something and will try pass is as an accident, but surprisingly, she is being really gentle.

Having her naked body this close to me, an urge to grope her rise within me, but well, I need to show some restraint right now…

"So, Nemesis, tell me this; are your godly powers affected in any way after becoming my slave?" I ask her casually.

"No, they aren't. I can still perform my duties perfectly. Thought well, there is a small difference; my minds feel completely free of the prayers and wishes of my worshippers. While it is greatly relieving, there are many concerning things as well," she tells me.

Hmm? She answered easily. That's unexpected…

"So, you feel that your powers are unaffected… even right now?" I ask meaningfully.

"I know what you are trying to ask, and I think you already know that answer. There are some ancient magic and laws which govern even the gods. And because of them, I cannot use my godly powers to meddle in mortal affairs, that is, help you using those powers.

"When you summon me, I lose almost all my powers except a few characteristic ones. In fact, the amount of powers I retain is directly proportional to how powerful you, my master, are," she informs me.

Haa~ That's a letdown, to be honest, though not completely unexpected. But well, if her powers do grow along with mine, I guess it's not that bad.

And one more thing…

"You see, when I broke your virginity, some of your powers passed on to me," I tell her.

"I want you to help me figure them out…"
