Sakura ( dom )

Tsunade had a special mission to train Sakura and break Naruto

Sakura is chosen to test a new tip of interrogation on Naruto he was told that it was a new method that could only be used on him with out long term damage

The method is to put a withdrawal seal on him but he first needs to be addicted to something so Tsunade thought why not make the brat get his crush then be crushed by her

Tsunade's plan was simple first Naruto will willingly be restrained then Sakura will sexually pleasure the poor virgin while not letting him cum with the use of seals then make him beg for relief and just at the most valuable moment Sakura will apply the withdrawal seal on to Naruto both making him in constant edge and absolutely devoted to the source of the pleasure but no matter how much he indulges in his addiction he will never get release his desire will only get stronger and harder to fight
