Naruto: tsunade's adopted heir

this will take place during and just after the tsunade retrieval mission.
......................................................................................
Naruto had gone to tanzaku town with jiraiya to find the next hokage tsunade senju. but little did tsunade herself know that the bet she would make with naruto would change all 3 of their lives forever.

tsunade would make a bet with naruto.
a bet too good for both jiraiya and naruto to refuse.
and one that tsunade would learn never to make again.

and that bet was.

"I'll give you one week to master the rasengan.
if you do I'll marry jiraiya
become fifth hokage

and make you my adopted child. plus
I'll tell you what the third never did.

as motivation to become my successor I'll tell you
who your mother and father were.

I'll even throw in my grandfather's necklace as collateral payment.fail and I get all your money and we never see each other again"

tsunade would then realize that some bets were better left unspoken. but when has that stopped tsunade before???. never. as she would soon find out. it's the last bet she would ever make with naruto Uzumaki.

I don't own naruto or it's characters.
their the property of Masashi kishimoto.
I only own the plot twist.
