Y/n arrive at Rias home and we see him with Azazel as the rest came into the room after they were finish from their hard training. Issei is in tears due to the fact that has been training in the woods all alone without his "pillow." Which Y/n just sighs.

Y/n: I think the point of that training was so you won't get distracted by something like that.

Issei: Shut up man! Not like you done any training.

Y/n: For your information I did. I visited the gym and let me tell you, that place was amazing. It was also cheaper which is amazing.

Azazel: (smile) Well glad your spending your time Y/n. As for the rest of you, rest easy for now. We'll be invited to a party tomorrow.

Y/n: A fancy dinner party at the underworld. Can't wait for that.

Rias: (smile) Everyone would be honoured to have you in the party.

Y/n: Yeah. Hey wait, where is Koneko? Isn't she suppose to be here?

Asia: She passed out during her training.

Y/n: (shocked) What?! How?

Kiba: Trains so hard. She was found laying on the floor. She resting but it isn't like her.

Issei: Yeah, hope she'll recover soon.

Y/n: I'll go and check on her.

Rias: Okay.

Y/n leaves the room and makes his way to the room where Koneko is in. He walk down the halls when he heard a call from behind and turn to see Millicas, Grayfia and Sirzechs.

Millicas rush over to Y/n and came up to him while Y/n high fived him.

Y/n: (smile) Hey Millicas. How are things?

Millicas: (smile) Great! I'm so glad to see you.

Grayfia: When we heard you were coming here, Millicas can't help but to search for you.

Y/n: Guess he found out the battle that happen with the Khaos Brigade.

Sirzechs: (smile) That and how you united other race. So, where are you off to?

Y/n: Gonna check on someone and see she is okay. You?

Sirechs: Getting things ready for the party tomorrow. You should come. It would be great to have you there.

Y/n: Sure I can come. After all its still my vacation after all.

Grayfia: (smile) Well we'll let you go now. Come Millicas.

Millicas: Okay mother.

The three leave Y/n be as he goes on and soon he arrive at the room. He slowly opens the door and finds Koneko laying in bed with curtains around her.

He walks in and soon approaches her bed and stare at her for a moment. Then he noticed something on her heard and he sees cat ears.

Y/n: Cat ears?

Then Koneko woke up and then sat up and when she spotted Y/n she is surprised.

Koneko: Y/n? What are you doing here?

Y/n: Heard what happen to you so I came to check to see  if your okay. By away you have something on your head.

Koneko noticed then decided to show him more then just cat ears. She remove the blanket to reveal a tail which Y/n is surprised.

Y/n: (surprised) Okay, I feel like your gonna to explain to me about this.

Koneko: I suppose I have no choice. I'm a rare species known as Nekomate.

Y/n: I heard a bit about that race. Heard that they are spirit cats who are under the rule of Magari.

Koneko: That's right. Before I met Rias me and my older sister were orphans but I still have my order sister. Then we were picked up by our devil's and service them as our masters. Things were fine until my older sister killed her master. When word spread about my sisters actions, they try to end me but I was saved by Rias brother and he introduces me to Rias.

Y/n: So you didn't told me or anyone that you are a Nekomate was so your afraid we may not trust you.

Koneko: It may sound stupid but i was afraid what others may say about me. The only person who know my race is Rias.

Y/n stood there for a moment then he climb into bed then gently hugged Koneko from behind. She blushes as he cuddle her which made her a bit better.

Y/n: You don't have to worry about anything. Your loyal and trustful around me and to Rias group. Those assholes who try to kill you because what you sister done needs to see that. I will always love you Koneko, no matter what.

Koneko: (blush) Thanks Y/n. I needed this.

Y/n: (smirk) No worries. After all your even more cute with cat like appearance.

Koneko blushes more then turns towards Y/n then lend her head against his chest and purred. He find it even more cute as he cuddle her even more.

Koneko likes this then Y/n lend down and kiss hee on the head. She blushes more as the two look at each other for a moment, smiled then they lend in and they kissed.

(Short lemon start)

They made out as Y/n fell back onto the bed with Koneko on top as the two let out moans of pleasure as they kept making out.

Soon they stop making out and Koneko sat on top of him, looking down at him then she go down to his trousers and took them off.

Then she begins to give Y/n blow job, Y/n let's out moans of pleasure whole Koneko kept going. After a short while Y/n can feel it coming then his dick erupted follow by him letting out a sigh.

He take some breaths while Koneko crawl up next to him as he turn to her a gentle touch her cheek then without thinking she said.

Koneko: Meow~

Y/n: (small chuckle) Aren't you a cute Nekomate.

She smiled with a giggle then Y/n gets on top of her, insert his dick into her then he begins thrusting it in. The two let out moans of pleasure as Y/n grab both Koneko's hands as they go at it.

Koneko: (moans) Keep going, ah~! It feels so good~!

He kept going, he increased his speed just a bit which turned her on as they kept going. During that Y/n lend in and kissed Koneko which she kiss her right back. After a few moans the two can feel it so Y/n goes harder and soon the two let out a moan of pleasure.

(Short lemon end)

They lay on the bed together for a moment, breathing heavily with sweat coming out of their body as the two lay in bed with Koneko cuddling Y/n while he cuddle her back.

Y/n: Feel better?

Koneko: (smile) Yes. Feel much better.

Y/n: (smile) So what will you do now?

Then Koneko thinks about it for a moment then she tells Y/n.

Koneko: I might want your help. I have this feeling my sister could be here and I want you to help me find her.

Y/n: And confront her? You sure?

Koneko: For sure.

Y/n sees how serious she looks so he gentle stroke her cheek then tells her.

Y/n: Sure, I will help.

Koneko: (smile) Thanks Y/n. I know I can trust you.

Y/n: And I can trust you as well in my life. Beside, how can I saw no to a cute girl like you.

Koneko: (smile) True. Gonna get some rest for a few hours. Then we go out and find her.

Y/n: (smile) Sure thing.

Then Koneko get some rest, stilling cuddling him as she purs which Y/n smile then lay there for a bit until she woke up.

(Sometime later)

The two are seen walking through the dark forest as they look around. Koneko was at front while Y/n follows her.

Y/n: Say you fail to tell me your sisters name.

Koneko: Her name is Kuroka. Unlike me, she isn't afraid to show her race.

Y/n: I see. What was the last time you heard or saw her?

Koneko: The news about her killing her devil master was the only thing I've heard about her. Nothing else.

Y/n: Welp, let's just hope she isn't doesn't try to ambush us.

Koneko: When it comes to me, she won't.

Y/n: Right.

They kept walking and at first there was no sign of her but then Y/n and Koneko feels like they were being watched. Soon they arrive at a large tree as they stop and look around.

???: It's been a long time hasn't it little sis?

They look around but they couldn't see her as she goes on to say.

???: Whose that you have? Is he your boyfriend? He looks very attractive, you don't mind if I tale him from you right?

Koneko: Come out. I know your out there sis.

???: Oh you remember me. I was worried you won't remember my voice. It's been so long since we last seen each other.

Koneko: Just come out and show yourself.

Then there was silence. Still they have theie gaurd up then that's when a black tail stroke Y/n's left cheek from behind then Kuroko appear next to him with a lick of us finger.

He gets started as he stumble back and turn to see Kuroko who is very much older then Koneko.

Kuroko: (smirk) A pleasure to meet you Dark slayer, I am Kuroko, Koneko's older sister. Heard a lot about you.

Y/n: How?

Kuroko: (smirk) I have my reasons.

Then she leaps over then and then lend on a tree branch above them. She then lick her hand like a cat then sat down on the tree branch.

Y/n: You are right. She really isn't afraid showing her race to everyone.

Koneko: I have a feeling you would be here.

Kuroko: (smirk) And you miss me huh sis?

Koneko doesn't say then Y/n step forward and said.

Y/n: So I know this may not be my business but Koneko told me what you did.

Kuroko: Oh how I kill my devil master?

Y/n: Yes.

Kuroko: Well he deserved it. I love to stay and chat but I gonna go now. Oh and one more thing, better watch out of the norse god.
