Surviving in a wild forest could be a difficult task, and Sakura was aware of that. Hunting dangerous animals, having to check if she haven't collected any dangerous fruits or mushrooms, these kind of things.
She was also trying to hide from other people, but that was more easy because, when some student dies at the Forest of Death, they think that was an animal or another ninja of the exam.

She also had to feed himself and Naruto, and clean his shit. Half of the time literally.

"Thankfully", Sakura had a piss fetish.
And she somehow began to like to clean Naruto. It gave hear a sense of motherhood towards Naruto, a thing she well knew he lacked, a thing she expected him to desire.

Naruto, otherwise, began to doubt if even there was another reality.

After some time, a time he seemed to even lose sense of, he began to wonder if the life before this prison even existed.

There was only Kurama to talk when Sakura wasn't there, and all Sakura did was fuck him and suck him, over and over again. He could still try to talk with Kurama about the life outside of the hole, but even then beast never felt so bored since it was born and got tired of reminding Naruto of everything. He was already on a prison, but he could see the outside. Now, he was really isolated from the world.

Also, he had to warn Naruto to not talk of Hinata and the kids when Sakura was around, or they...Naruto would be choked again.
When she was out, Kurama used his chakra to try to strengthen him but it was clear Naruto was getting weaker, week by week, even being feed.

And then, one day, Naruto realized, Sakura's belly was  slightly bigger.

"Sakura did you get fatter?" said him.

She laughed devilishly.

"Oh, you silly boy. Don't you see?" said her, passing her left hand over the belly. " I'm pregnant."

Kurama snapped out of its boredom when he heard those words.

What the fuck? Oh no, now this got really, REALLY serious.

Kurama?

Ask her who is the father.

"Sakura, who is the father?"

"Oh, silly, it's you. Who more? I'm living this forest with you for maybe six months now."

Six months!? Alone in this fucking forest, only us three...now four, I think!? Are you fucking kid...

Something suddenly trembled above the structure, like the feet of several people, and Naruto clearly could see the head of someone trying to look inside the hole on the top that gave light to the structure.

"They're here! She's imprisoning him! You can attack!"

"But who..."

Sakura was interrupted by a chain drilling through the rock and that curled around her neck.
"Argh!" she said as she was pulled to the opposite side of Naruto's head.

"Those chains of chakra...This only can be a ninja of a certain clan..." commented Kurama.

On the other end of the chain, there was a redhead ninja with glasses, without doubt one of the best sensors of the world.

Sasuke was at her side, because he would be the only person she would obey.

"She is really pregnant, as I thought. I can feel it clearly now.." said Karin.

"How much?"

"Two, almost three months."
"Keep that way. ANBUs, avoid, hitting her...too much. She's pregnant. Also, look around for other entrances. I doubt she enters it by that hole on the top."

"Alright sir." said the ANBUs to the new Hokage.
