Chapter One

Kurenai Gets It

"To perform a proper Genjutsu, you must focus on your Yin-chakra, and dampen your Yang-chakra, as the presence of Yang-chakra is the antithesis of Genjutsu," Kurenai explained to her current student, Uzumaki Naruto.
"I can help you with this one, kit," said Kurama. strong"If you allow it, I can suppress your Yang-chakra, seeing as only my Yin-chakra is sealed inside of you."
"Go ahead, Kurama," said Naruto. "I hereby give you, Kyuubi No Kitsune, permission to suppress my Yang-chakra."
"Thanks for trusting me, kit," said Kurama, wiping away a tear from her eye. "You have been so good to me, even though it is because of me that you never knew your parents."
"Don't sweat it, Kurama, I know that it was Uchiha Madara's fault that you attacked that day," said Naruto. "Now go ahead and suppress my Yang-chakra so that I can perform Genjutsu and impress Kurenai-Sensei."
"Sure thing, kit," said Kurama, focussing her chakra on suppressing her container's Yang-chakra and enhancing his Yin-Chakra. "Go and get her."
Naruto nodded and began making the hand seals in order to perform the Genjutsu. "Uzumaki Clan's Secret Technique, Hell Illusion!" said Naruto as he completed the Genjutsu, trapping his Sensei in a hellish genjutsu of his own design.
"It took Kurenai a few minutes to de-spell her student's genjutsu, and when she did, she was noticeably winded. "Well done, Naruto-kun. That was a fantastic technique and flawless Yang-suppression. You deserve to choose a reward." Naruto did not hesitate and immediately approached his tired Sensei and kissed her passionately. She immediately returned the kiss, sensing where this was going and not minding in the slightest. Clothes were quickly shed as the knuckleheaded ninja and his sensei surrendered to their passion for one another. Kurenai got onto her hands and knees and wiggled her rear invitingly, giggling as Naruto slapped it. He rubbed his member against her wet heat for a few moments, making sure it was well-lubed before lining up with her puckered asshole.
"What do you want, Kurenai-chan?" asked Naruto, putting an emphasis on the honorific.
"I want you to fuck me hard, Naruto-kun," replied Kurenai.
"Where do you want it?" asked Naruto teasingly.
"In my ass," replied Kurenai. "Please, Naruto-kun, your sensei needs it in her ass." Naruto grinned and pushed forward, his member being engulfed by his sensei's tight asshole. He continued pushing forward until he was balls deep in his teacher's rectum.
"How do you want it, gentle or rough?" asked Naruto before nibbling on his sensei's earlobe, causing her to moan.
"Rough, I don't want to be able to sit comfortably for a year!" exclaimed Kurenai. She truly wanted her student to reck her. It was a new feeling, and one that she couldn't properly explain.
"My sexy Sensei's wish," said Naruto, "is my command." He pulled out until just the tip was inside her before pushing forward again hard. Again and again he pounded his sexy Sensei's tight ass. She moaned loudly as he roughly fucked her tight asshole. She came at least three times before Naruto stopped and pulled out. He then entered her pussy, groaning at her tightness as he tore through her barrier. He was close to his climax, and wanted to claim his sexy sensei properly as one of his mates. Just before his climax, he bit into her neck, infusing his bite with the Kyuubi's chakra and drawing blood. Kurenai moaned in pain and pleasure as Naruto bit into her neck before releasing his load into her waiting womb. "You are now mine for life, Kurenai-emchan."
"Good," said Kurenai as she cuddled with the blond jinchūiki. "I'm glad." The couple waited a few minutes before getting up and getting dressed. "Thank you for being my first and my last, Naruto-kun."

"I'm glad that you were my first, Kurenai-chan," said Naruto. The two kissed passionately before parting ways. "Who should I claim next?"
"I'm sure Anko would be more than happy for you to claim her," mused Kurenai. "There's also that girl from the ramen stand. What's her name? She might be a civilian, but she sure is beautiful."
"Ayame," said Naruto. "Or Anko. Two marvellous options. I'm glad that I have you to ask for advice, Kurenai-chan"
"I'm glad to give you my advice, Naruto-kun," said Kurenai.
