Sometime later
At Konoha, shopping area
Naruto is annoyed of 'Yuiko' because she's been asking way too much of him, from traits, clothes, and attention.
'Great my fiance is a bitch I don't think it will work between us, and I hate her' says Naruto in his thought as he hopes that Samui comes back soon to bring the Daimyo with her, Naruto is so close to ending her life so close.
As 'Yuiko' come up to Naruto and says "darling, will you p-"
"Juiko." Naruto turns and Sees the Fire Daimyo, Samui ten Samurai and a woman he does not know.
"F-Father!" says 'Yuiko' as Naruto says "what's going on?" as the unknown woman come up as her massive Double J breasts bounce as she wearing a royal Kimono as she says "This is my twin sister Juiko, I am your real Fiance Yuiko" as Juiko says "no way! She's lying! As she's Juiko!" as The fire Daimyo yells "there no point of Lying Juiko! Give up this act now and tell me why did you do this! Right now" as he's in all dad mode.
"Because I did not want that Fiance you put me within the marriage contract. As he's old and gross! Why does my sister get to be with someone of her age."
"That man was the father, not your Fiance and Because Kushina and Minato were my friends and I want the friendship to stay strong," says the Fire Lord as he says "but after of what you have done, locking up your sister in a closet! Taking her place, failing the son of my two friends, Juiko, I'm very disappointed in you, as Pains me to do this" as Juiko says "w-what are you going t-to do F-father?"
"I have no choice but to Exile you Juiko, as in now, you are no longer a Daughter of the Fire Daimyo, you are forbidden to use our family name, and you will be a strip of everything."
Juiko starts to cry, and she runs away, to be never seen from again as Naruto could say after seeing that, "Damn that was cruel."
"I had no choice. It is better than death" says the Fire Daimyo as Yuiko sighs as she looking where her sister had run at as Daimyo says "thank you for bringing this to me miss Samui" as he and his men walk away, Naruto and Samui look at Yuiko, and then they head back the house, but Naruto come up her as she doesn't say a word as their heading home.
"You ok?" asks Naruto as Yuiko sighs and says "not really, since my sister knock me out, lock me in my closet and try to pose as me and take you as her husband, it's a lot to take in."
"Yeah Agreed it is, but I had no idea no idea about this contract at all that was a lot to take in," says Naruto as she says "well you weren't meant to know until you are 18 after all."
"Well That was a bit harder to do really," says Naruto as the two making their way to the Uzumaki house, as their get there, as their see Grayfia who is panicking as all hell as Naruto come up to her and say "what's wrong Grayfia? Why are yo-"
"Their water Broke. Their at the Hostal right this moment Naruto." said Grayfia as Naruto says "I need to go now." as he runs off like there's no tomorrow, as Yuiko is blinking in surprised by this. Samui Giggles.
A couple of days later
Konoha Hospital
Samui appeared at the Hospital with Yuiko as their walk up to the room that Kushina is staying in as she's resting in bed, as Naruto is sitting by himself, Naruto is worried about Kushina though the kids are beautiful and not only that, Rin, Anko, Lily also give birth as well as their resting up as well as do Naruto as all the worried had put him to sleep.
They had two boys and two girls they are Rose for Lily, and Rina for Rin. Now Menma for Kushina and Tsukune for Anko, as Samui says to Yuiko "I think it's best, we come back later, their sleeping" as she walks back home as Yuiko follows.
Later at the Uzumaki house
"So Samui Tell me something why did Naruto run off like that. Like they were his kids if I may ask?" Asked Yuiko as Samui looks at her as both at the door as Samui "it's a long story, come on, I will tell you as we make something for them when they wake up."
They start to make something as Samui tells Yuiko they are his kids and she is not his only Fiance. "Wait what do you mean I am not his only Fiance?" Asked Yuiko as she is slicing the chicken as Samui goes on telling her.
"Because I am also his Fiance. I may be his Adopted Sister, But I am also to be his wife soon he did propose to me" says Samui as she is boiling the water.
"But why Am I just finding out about this. I don't mind sharing Naruto but why am I finding out now?" says yuiko as Samui says "well first off, we didn't know that you and Naruto are engaged and seems my mother had forgotten to tell us but then again, she was rising both Naruto and me as a single mother, so it must have left her mind"
"Fair point there but the three of us will talk about this later we have food to make," says Yuiko as both of them resume cooking.
Couple days later
Naruto is sitting on the couch next to Samui, and they are facing Yuiko as all three sit there for a good while as their thinking of what to say, "S-So you are not against sharing me?" Asked Naruto as Yuiko says "not really but the problem is that, who will be the main wife? Even you had a purpose to Samui, but I'm engaged to you first as you are to me."
"That is a problem how do we choose the main wife?" Asked Naruto.
Samui then had an Idea "Well I can think of one way. A challenge the winner is the head wife." as Yuiko says "what's the challenge?"
Samui says "simple, you and I are going to see who makes Naruto cum the most."
"Uh, Samui-nee-chan are you sure that is a good Idea? I mean you want to wait until our wedding for more. However, are you sure?" Asked Naruto as Samui says "I know this, and this is something she and I have to do" as both get up and face each other as their breasts are against each other, with Samui's Double K cup Breasts against Yuiko's Double J cup breasts, as Yuiko says "who is first?" as she looking at Samui as Samui herself says "you go first, after all, it won't be fair if I go first, and tomorrow it will be my turn, with that let the best wife be win"
"Very well Samui I accept the challenge. So yes may the best wife win." Said Yuiko as Samui says "I will let you two be" as she walks away to her room as Yuiko says "so where do i-" Naruto picks her up and takes her to his bedroom.
