Yn Is An Uzumaki!? {Kawaki X M!Reader}

Chapter 3

Both teens were tired out from training with each other for hours to point where when Yn got into their room he ended up falling asleep on Kawaki's bed instead of his own.
Kawaki thinks Wow, Yn must have been extremely tired to have fallen asleep instantly. Especially on my bed.
Kawaki chuckles quietly and decides that it's best to not wake up the older boy and moves him onto the bed fully and climbs in next to him, it is a double bed so it is big enough for the both of them. Kawaki almost drifts off to sleep when he feels two arms wrap around his waist and pull him in. He opens his eyes to see Yn's face inches from his. He tries to pull away, but with Yn being stronger physically he fails. Yn snuggles into Kawaki's neck, still fast asleep. Kawaki sighs and hugs back. He then falls into an unusually blissful sleep. When Yn woke up, his eyes still closed, he felt a gentle breath on the top of his head. He opens his eyes to see Kawaki's chest.
Yn thinks Did I really cuddle with Kawaki!?
Yn blushes at the thought and hears Kawaki make a sound in his sleep. Kawaki then moved downwards and ended up face to face with an awake Yn. Yn blushes and turns his head away. Kawaki then wakes up slowly to see Yn looking away with pink clouds on his cheeks.
Kawaki says "O-oh, sorry"
Kawaki turns his entire body around eternally screaming. Yn looks back and sees Kawaki's back to him.
Yn thinks Ah, fuck it.
Yn wraps his arms around Kawaki's waist and spoons him.
Kawaki says "W-what are you doing!?"
Yn says "Spooning you?"
Kawaki hides his face in his pillow and says "We just met yesterday!"
Yn says, teasing him "So?~"
Kawaki turns red and tries to pull himself away from Yn's arms, which would result in him falling off the bed.
Yn clutches tighter and says, still teasing him "Uh uh uh~ You aren't going anywhere~"
Kawaki looks at the time to see it's 7.30am.
Kawaki quickly sits up and gets out of bed.
Yn says "Aw~ I was enjoying that"
Kawaki says "Whatever, I have to go to meet my team, you will have to go with Naruto to get belongs and stuff"
Yn says "Oh yeah, but why aren't you coming with us?"
Kawaki sighs and says "Because, my sensei had, unfortunately, set up a time to meet him to talk about a mission we will go on soon"
Naruto, coincidentally, shows up at the door and says before seeing Yn in Kawaki's bed "Ok so, Kawaki you aren't seeing Konohamaru today, I agreed with him to reschedule it to tomorrow and to introduce Yn to the team"
Once Naruto said that he saw Yn laying in Kawaki's bed and says "I'm not gonna ask why Yn is in your bed Kawaki but, we have an hour before we are going out"
Naruto disappears from the door and both teens are thinking Yn/I is/am joining my/Kawaki's team?
Kawaki thinks alone That will be fun, having someone I ACTUALLY like on my team, I mean, Konohamaru-sensei is chill but, Sarutobi is an extremely irritating bragger and that Nara kid in annoyingly lazy. So it would be nice to have someone like Yn on the team

{Side note: Shikadai will be 13 and Mirai is 15}

Yn gets out of bed and says "Seems like you will be seeing alot more of me~"
Kawaki says "W-whatever, let's get changed"
Yn smirks, heads over to his clothes and takes off his shirt to reveal relatively toned muscles, board shoulders and a few scars on his chest and back. Kawaki watches the entire time being as red as a tomato and a nosebleed threatening to come.
Yn sees Kawaki's state and says "Like what you see?~"

{Side note: As you can tell, Yn is very flirtatious and teasing with Kawaki. I'm doing that because I want to}

Kawaki peels his eyes off of Yn's perfect body and thinks Why did he have scars on his chest and back? I'll ask him about it later
It was Yn's turn to blush when Kawaki takes off his shirt to reveal his lean, slender body with acutely toned muscles but had a surprisingly small waist with narrow shoulders. Yn finishes changing and sees the shorter and younger boy shirtless. Yn blushes and has a nosebleed.

{Side note: Sorry for all the side notes but, Kawaki will be shorter than he is in canon so, Yn is 5'10 and Kawaki is 5'7. I didn't say this in the first part but, Yn uses the Transformation Jutsu to hide his whiskers so no one finds out who his father is}
