Endurance

Naruto raised a eyebrow at that "Endurance? You mean like pain tolerance or stamina?" Really he didn't see why she was worried about that. Sure she wasn't, well HIM, but she was respectable already well beyond what Hinata, Ino, or Kiba had ever been.

She nodded resolutely "Yes endurance. I watch Boruto train and it just makes me so jealous how he can just practice for hours then laugh it off and play like he just woke up. I know I'll probably never match him but I still want to get closer to that."

Ah, that made sense to Naruto. Sarada had always been competitive with Boruto, in his private opinion he didn't know why, he loved his son but Boruto was several notches below Sarada as a ninja, to flippant and self-centered even after all these years, better then when he was a kid at least but not enough to match a hard-worker like Sarada.

As he was thinking his eyes couldn't help but trace her legs, past her wonderful hip, her toned stomach, and bouncy breasts. What he'd do to her if given the chance was to never be hinted at to Sakura.

"And how do you want me to help with that? Sorry to say Sarada but while I know a lot of things, the only way reasonable I know of to help endurance is long, exhausting, boring work. And you don't need me to help with that." Although he would help, or at least watch. Because watching Sarada for hours as she moved and bounced sounded as frustrating as it did enjoyable.

Sarada actually had an answer for him though "Actually I had an idea. I overheard Momma and Ino speaking about the 4th war and they mentioned you had a trick where you gave people this red Chakra to help them out. I was thinking if you gave me that I could work for longer then I could normally, and my body would adjust to that until I didn't need the help to do it anymore."

Naruto cocked his head in thought. He had never used Kurama's Chakra like that before, despite being his friend now Kurama's Chakra still felt like evil made manifest, so he limited such obvious displays of it to make sure no one was uncomfortable or had heart attacks.

His eyes naturally drifted down once more, her 'shorts' were just so teasing. Which is when he got an idea of how to use this.
