With a Smile on Her Face (гет)

Naruto successfully defeated Pain and has finally won the day, gaining the approval of his peers and the adoration of Konoha. But in all the excitement, he's forgotten something important – someone important. Someone who had sacrificed everything for him and then simply watched from the sidelines with a smile on her face.
Not realizing he's forgotten anything, Naruto thinks everything is fine until the Kyūbi talks to him again for first time since the battle where it almost got free. But instead of just threatening death and destruction, the Kyūbi claims they are deathly sick. The only cure is not something Naruto is comfortable with at all: as much sex as possible in the next seven days, with all the kunoichi they can find to help him. With the last expert on the seal, Jiraiya, dead and the best medic in the world, Tsunade, still in a coma, Naruto doesn't have many options. Will he remember what he's forgotten in time to avoid dying along with the Nine-Tails, possibly taking the entire village with them?
