A lesson in focus

While Naruto was absorbed in Kurenais nudity, the Jonin spoke up about her idea of a lesson. "I noticed that your chakra control isn't as good as Ino's or Sakura's. For a moment, I thought it was my failure as a teacher not to have taught you this properly, but now I think I have come up with the perfect teaching method for you.", she told her student.

"And what would that be?", Naruto asked, rightfully curious what she meant.

The answer surprised him. "Naruto, I want you to refrain yourself from cumming.", Kurenai said him, sounding surprisingly stern.

Naruto, of course, couldn't just agree with that."Huh? But why?", he asked, perplexed. He didn't get it? Wasn't sex about enjoying it and not an exercise?

Kurenai shook her head. That was what still seperated Naruto from being a boy to becoming a man. "What's necessary not only bed but also in ninjutsu is restraint and focus. That's what I am trying to teach you here. So, are you ready?", she asked him.

"W-What if I can't do it?", Naruto asked. He didn't want to fail his teacher, even more so if it meant pleasing her AND also meant he would learn important stuff.

But Kurenai just chuckled, amused by his eagerness that prevented him from seeing the full picture. "Oh Naruto, this isn't a pass-fail situation... if you cum, will simply do it again. And again. And afterwards, you can still keep doing this exercise with your girlfriends. After all, Naruto, you have to keep up with 4 females right now, huh? I think they're gonna appreciate you lasting longer than you do now.", she reasoned, and even if Naruto hadn't heard any complains from his girlfriends yet, he also doubted they would mind if he only got better.

"Ah, I get it. Alright then, I'll give it my very best, Kurenai-sensei!", Naruto asked, now fired up about the prospect of this training.

"Oh, I do hope so, Naruto.", Kurenai said with a lusty smile as she got on her knees in front of him...

After the failed attempt at exposing a secret (not unless you count the discovery of Narutos massage talents a secret), the girls returned to the lobby, which was still empty. They sat down there and sighed simultaneously, but all for different reasons.

Ino of course sighed because she had to wait even longer for Naruto now.

Kin sighed because she was still not sure what would happen, and if that teacher spent time getting a backrub instead of talking with the Hokage, it would take some time for her to get an answer, which just kept her on the edge. Also, she had kind of hoped to run into her friend Tayuya here... she just had to be here already... so where was she?

Sakura on the other hand again still mourned the loss of another chance to talk to Naruto. Also, she had an equally important talk with Ino, but she couldn't have that now, either, with Kin around. It appeared as if both girls mentally agreed with each other to postpone that discussion until they were alone.

So, the trio sat there in silence for a few minutes. But, as to be expected, it was Ino who broke the silence by saying something unexpectedly. "I think we owe you an apology, Kin.", Ino said, seeming a little **** to admit this. After all, she had so strongly opposed Kin, but in the end, she had turned out to be alright.

"Huh? Oh no, you don't have to...", Kin said, being modest. However, when she tried to adress the girl in front of her, the name just escaped her.

Kin noticed her hesitation and realized something. "Oh, that's right, we haven't even introduced ourselves, right? I'm Ino Yamanaka. My family runs a flower shop here in Konoha.", she introduced herself.

"Haruno Sakura. Well, there's not really much to say about my family...", Sakura said with a small chuckle.

Kin was rather **** to say anything about her past and Sakura and Ino had the presence of mind not to ask her. Instead, they chatted with her while trying to avoid topics such as her home and her team.

Nearly thirty minutes had passed and Kurenai was still doing her best to pleasure Naruto with her mouth. However, when she looked up, she saw that, while he was certainly enjoying it, he didn't seem even close to cumming yet, which confused her a little. "Well, how is it? Are you holding up well?"

Missing the lack of mouth around his dick, Naruto moaned in disappointment before answering. "Y-yeah, kinda... Ino-chan's blowjobs are the best, so I can endure them somewhat by now...", he explained.

That statement made Kurenai feel a twinge of an emotion she hadn't felt for a while... but what was it? Jealousy or just a broken pride? "Hrmmph, so my technique is lacking then?", Kurenai pouted. "Alright then, guess I'll have to give you something harder to test then...", she decided and got up.

As Naruto looked where she was going, he followed every sway her full hips made. He watched intently as Kurenai climbed on the bed and spread her legs wide there for him. And as if that wasn't enough of an invitation already, Kurenai also spread her lower lips with two fingers for him.

"Fuck me. Fuck me as hard as you can, but don't cum, Naruto.", she reminded him, although Naruto had a hard time even hearing her words as his gaze was transfixed on the spread pussy in front of him. Already, there were some juices running down Kurenais folds, almost ordering him to finally get inside her.

Of course, he couldn't resist that temptation for long. As he approached her, Naruto aligned his cock with Kurenais entrance and was almost sucked in immediately. Naruto groaned. Kurenai-sensei's pussy was just as tight as any of of his girlfriend's, if not tighter. He wondered if she was using some sort of jutsu for this, but then again, he didn't really care. It felt way too good to question it.

Just on instinct, he began to establish an even faster rhythm than he usually did. He kept plowing away into his sensei, whose only response were yelps and groans of pleasure. More and more, Naruto was about to get lost into this bliss and forget his original goal.
