Gon's sister (killua x reader x hisoka)

First date

Y/n Pov
When I went inside the hotel I decided to have a shower. A little while after I get in I hear Killua and Gon enter the room. I get out with my (f/c) pj's on. Gon went in the shower leaving me and Killua alone. "How was your day Kil? " I said trying to break the awkward silence. He looked at me and smiled, "Pretty good even though... " He paused in the middle of his sentence and sat next to me, then wrapping his arm around my waist pulling me closer to him, "I didn't have the love of my life by me. " He said while smirking down at me.

A blush found it's way on my (s/c)  cheeks. He smiled and kissed my lips I kissed back of course.  After a few minutes of this we parted for air, he looked at me then said, "Hey how about we go on  a date tomorrow? " I thought about it for a moment then agreed saying, "Sure I would love to! " We agreed that we would just wing it and just walk around. After that he got into the shower when Gon got out. We all layed down and went to bed.

The next day

Killa POV
I woke up looking at Y/n beautiful face. I smiled and kissed her soft and plump lips. Then I got up and and got dressed. Today's the day, Y/n and I first date. Even though we decided we were just going to wing it I planned something special.

I came out the bathroom to hear. Gon and Y/n talking, "Come oooonn big brother pleaaaaasee? " I heard Y/n whinning to her older brother.  I waked in the room and said, "Morning guys what's going on? "Y/n turned to me, ran and hugged my waist saying that Gon won't let her have any cake for breakfast.

" No Y/n you can't that isn't healthy ", Gon lectured her. After a while of this they eventually got dressed. I swear Y/n looks so cute today, she's wearing a (f/c) shorts with a black tank top on, and (f/s) [ (f/s) =favorite shoe]. After we left her hotel room we split ways with Gon as he said he was meeting up with Lerio and Kurprika to try some new cakes at Sweet tooth candy and sweets shop. [I made up the name it's not in the anime ]

Third Pov
While the couple were looping around, they stopped at a local cafe to have lunch. Killua had sandwich while Y/n had a (f/l/f)  [(f/l/f)  =favorite lunch food ] when they were done they walked around. They stopped at the park and sat under a tree.

Killua was holding Y/n in his arms. After a while of talking they kissed.

Y/n Pov
We started to kiss, he deepened the kiss by pulling me closer to him. This was heaven, " Mmm" I muttered while kissing. We would've ended of making out if Killua stopped and said that he had something special he wanted to show me.

Killua Pov
After our little make out session I led her to a place where Gon told me that she loved to go. When we got there led her to the back where there was cakes, candy, cookies everything. "Oh... My... Gosh... KILLUA I LOVE YOU SO MUUUCHHH!!! " she said while hugging me to the point where I couldn't breathe. "Y/n...love...i can't breathe" I said,  then she instantly started to stuff her face.

Then after that it was around 8: 00 so I paid for the bill and we started to walk back to the hotel. Everything would've been perfect until he came along.

Hisoka Pov
After watching them all day I finally had enough. When I walked in front of the couple I was pissed. That should be me holding her, that should be me making her smile, that should be me kissing her soft lips. Not him.

They looked at me with a confused look well not Killua Y/n did. "You look like you had fun little doll" I said looking at her. "Well now I hope you know during that time you were with him I was watching you. Your smile the way you talk and laugh. I saw it all but it was with the wrong guy you should be with me not this guy. So come on with me. " Then she looked at with me giving me a death glare.

Y/n Pov
I was getting tired of Hisoka at this point. "You just don't get it Hisoka. I told you I love Killua not you and if interrupt us again I will personally beat you up. I'm not as week as I look so try me or say I'm with the wrong guy you'll regret it. Now if you know what's good for you back up now. " He and Killua looked surprised I grabbed killua and we walked pass him and got home.

After Killua shut the door he started to laugh. "Whats so funny? " I questioned "That was great Y/n I love you so much " he smiled and looked at me in the eyes. After we both had our showers we cuddled in bed. After kissing one more time and Gon getting back we all went to bed.

There's another chapter. More fighting sences in the next one. Until next time peace!
