While Kasumi showered—Kenshin went to the master bathroom where he found Natsumi undressing for a shower. She had just pulled off her nightie and remained in neat black panties.
Kenshin approached from behind and shamelessly spanked her ass—eliciting a cry of surprise from the girl. As soon as she realized who stood behind—she immediately purred and allowed him to hug her.
He tenderly stroked her large belly and kissed her neck—enjoying her tender moans. Natsumi had missed her beloved's caresses very much—so immediately melted.
After arriving in this world—Kenshin became more and more enduring sexually each day, and at the moment could have sex about ten times a day—so caresses with Kasumi didn't leave him indifferent.
As soon as both undressed and entered the shower stall—Kenshin immediately began caressing his wife's body with special tenderness—pressing against her back. His cock settled neatly between her plump thighs—pressing against her pussy.
"Uuuunngh! God—I missed you so much…" Natsumi moaned and squeezed her thighs—rubbing her pussy against the thick shaft of the large cock.
"Uuuugh—I missed your little pussy too… When you give birth—we'll pick a day, and that day I'll fuck only you…" Kenshin whispered in her ear—gently biting the lobe.
"Aaaah! God—that's a wonderful idea! Uuuunngh—can't wait…" Natsumi purred through moans.
Both were incredibly aroused—so climax didn't take long. After several minutes Kenshin was already moving his hips—stimulating his cock against Natsumi's hot wet pussy.
Experiencing an almost simultaneous orgasm—Kenshin washed the girl—holding her from falling, then washed himself and together with her left the bathroom—meeting Aya with hands on hips.
"So you're having fun without me?!" the girl asked in a displeased tone—but immediately fell silent as soon as Kenshin pulled her into his embraces and pressed his lips to her sweet cherry ones.
Aya immediately melted—and former displeasure instantly dissipated. In fact she wasn't jealous of Kenshin with Natsumi at all—and only begged for attention from him. She liked feeling loved—and she and Natsumi had many plans how to get attention and care from Kenshin.
Discussing several matters with the girls—Kenshin spanked both on the ass and headed to the gym—fortunately his sons did warm-up an hour before breakfast. Kenshin made them train their physical body almost at the same pace as taijutsu masters. He still dreamed of somehow obtaining the Eight Gates technique—but didn't know how or where.
He remembered that—if believing what was shown on screen—Maito Guy's father somehow experimentally awakened this technique without outside help—but didn't know if it was true or if the real world differed here too.
The fact was his sons were born with base physical strength directly depending on the "Talented Offspring" skill—meaning at some point any born son would have innate physical characteristics no less than the most genius taijutsu masters in history—and then awakening the Eight Gates technique would become only a matter of time.
He tried asking Natsumi about this technique—but the girl knew nothing concrete except that this ability might be even rarer than Kekkei Genkai. She didn't even know there was one such shinobi in Konoha. Kenshin chalked it up to Guy's youth and Natsumi's lack of information.
As soon as Kenshin entered the gym—all sons mentally greeted him. They would gladly approach and express respect—but Kenshin forbade distracting with such nonsense.
While he had free time—Kenshin decided to transmit useful knowledge and teach Third and Fifth the "Katon: Hosenka no Jutsu" technique—which almost all his Sharingan sons had already mastered without problems.
First he extracted the necessary information from Ichiro. This took about five minutes—since Ichiro already knew how to behave and what to do to ease father's work.
After that he rested ten minutes and digested all received information. He had tried many times to awaken chakra—doing everything as in his sons' memories—but nothing worked. He suspected the "system" had imposed some ban on his body—not allowing development of any energies not provided by the system itself.
Kenshin increasingly felt his arrival in this world and the "system" itself were planned by someone. Everything looked like a game—with a bunch of restrictions and conventions. He had several times tried mentally addressing this unknown entity—but received no answer and deep down understood he likely never would. Even the strongest being in this world lacked qualification to receive any answers from entities capable of tearing a soul from one world and moving it to another—incidentally granting a "system" ignoring physics laws.
After resting—he called Third and Fifth—telling them to sit opposite. They obeyed and did everything father said. The procedure went very successfully. Kenshin already knew how to direct his sons' consciousness in the right direction and could seize part of the initiative himself. Their completely submissive minds didn't resist Kenshin's mind intrusion at all—so everything went very smoothly. In half an hour he transmitted all information about the technique to both—and everything else depended only on their abilities.
"Thank you, father!" Third and Fifth said in unison—feeling huge joy. All sons from Natsumi had recently been quite depressed—envying sons from Aya who awakened Sharingan thanks to father.
The other children from Natsumi were also very encouraged and harbored hope that father would help them become stronger.
"The best thanks will be hard training and work for the family's benefit. Don't rely only on me. If you don't train diligently and meet the requirements for learning the ability—I can't help you."
Kenshin never stopped motivating them and setting them on the right path. He didn't know how to strengthen the talents of already born children—since even to the unarmed eye it was noticeable how later-born children achieved results a little faster than their older brothers.
