I do not own Naruto.
Kakashi had Naruto tied to the bed, straining and bucking.
So gorgeous.
He ran a hand down the near-naked man's side. "I wonder what they'd say if they saw us like this?"
Naruto laughed breathlessly. "You're thinking about them when you've got me here?"
Kakashi hummed and licked the inside of Naruto's elbow. "You're right, this wouldn't change their tune. Maybe when you have me tied down."
"You should get started if you want to see these ropes again anytime this month," Naruto threatened. It was less effective due to the moan that preceded the statement.
"As you wish, my prince."

"Can I see?" Yamato asked.
"Hm?"
"You know, the-" Yamato gestured to his wrist.
Given that Sakura and Sai were just a few meters away while Naruto was off patrolling, Kakashi felt his confusion was justified.
But, well, he did enjoy showing it off.
Kakashi took off his glove with a flourish and presented his wrist to Yamato.
"And on his neck, he really…?"
Kakashi nodded happily.
"What's that?" Sakura interrupted.
Both she and Sai came over to look at the twin scars on Kakashi's wrist.
"Is that a bite mark? Wait, from that time you had it wrapped. I could have healed that, you know!"
"I didn't want you to," Kakashi informed her.
"Why would you wish to keep a wound?" Sai asked.
"It's an old tradition among some of the elite ninja," Yamato explained. "It's a claiming mark. Most just get tattoos, or brands. Bites are more personal."
"'Claiming' mark?"
"It shows that they belong to the one who gave them the mark. Their lives, their loyalty, their skills. Everything you are, permanently and above all else."
Kakashi traced his scars, smiling slightly.
"You're proud," Sakura said in realization. "Of being marked like that."
"Extremely."
"Is belonging to a person similar to being a tool of the village?" Sai asked.
"In many ways," Kakashi agreed. "But generally, particularly outside of Konoha, ninja who are 'tools' are expected to give up their individuality, unless it improves their skills. When one person claims another, they're accepting everything, including that person's personality."
"So Naruto has to put up with your Icha Icha," Sakura joked.
Naruto wrapped his arms around Kakashi's neck. "It provides inspiration." He plopped his head down into Kakashi's hair.
Sakura flushed. "Sorry. I can't believe you bit sensei."
Kakashi felt Naruto's wide grin. "I have very sharp teeth."

Kakashi could barely breathe he was laughing so hard.
"Y- you! You're not ev- eep!"
"What was that, Naru?"
"The one being tickled!"
