While Kasumi showered, Kenshin went to the master bathroom, finding Natsumi undressing for her shower. She'd just pulled off her nightie, left in neat black panties.
Kenshin approached from behind and spanked her ass unceremoniously, making her yelp in surprise. Realizing who it was, she purred and let him hug her.
He gently stroked her big belly and kissed her neck, enjoying her soft moans. Natsumi had missed her beloved's caresses badly, so she melted instantly.
Since arriving in this world, Kenshin grew more sexually enduring daily and could now go about ten times a day, so the Kasumi session hadn't left him indifferent.
Once both undressed and entered the shower stall, Kenshin tenderly caressed his wife's body from behind, pressing to her back. His cock nestled neatly between her plump thighs, against her pussy.
"Uuuunngh! God, I missed you so much..." Natsumi moaned, squeezing her thighs and rubbing her pussy on the thick shaft of his big cock.
"Uuuuf, 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, nibbling the lobe gently.
"Aaaaah! God, great idea! Uuuunngh, can't wait..." Natsumi purred through moans.
Both incredibly aroused, climax came quick. Minutes later, Kenshin thrust his hips fully, stimulating his cock with Natsumi's hot, wet pussy.
After near-simultaneous orgasm, Kenshin washed her, steadying her, then himself, and they exited to find Aya with hands on hips.
"So you play without me?!" the girl asked grumpily but silenced as Kenshin pulled her into his arms and pressed to her sweet cherry lips.
Aya melted instantly, her annoyance vanishing. She didn't truly envy Natsumi but craved his affection. She loved feeling loved, and she and Natsumi had many plans to get Kenshin's attention.
After discussing a few things, Kenshin spanked both asses and headed to the gym, where his sons did pre-breakfast warm-ups. He trained their bodies almost like Taijutsu masters. He still dreamed of getting the Eight Gates technique somehow but didn't know how or where.
He recalled that, per the screen, Might Guy's father experimentally awakened it alone, but wasn't sure if real or if this world differed.
The fact was his sons were born with base physical strength tied to "Talented Offspring," so eventually any son would match history's genius Taijutsu masters innately, making Eight Gates awakening just a matter of time.
He'd asked Natsumi, but she knew little beyond it being rarer than Kekkei Genkai. She didn't even know Konoha had one such shinobi. Kenshin chalked it to Guy's youth and her ignorance.
Entering the gym, all sons mentally greeted him. They'd gladly approach but he forbade distractions.
With free time, Kenshin decided to impart knowledge, teaching Third and Fifth "Katon: Hosenka no Jutsu," already mastered by most Sharingan sons.
First, he extracted info from Ichiro in about five minutes, as Ichiro knew how to assist.
Then he rested ten minutes and processed it. He'd tried awakening Chakra like his sons' memories but failed. He suspected the "system" barred his body from energies outside its provisions.
Kenshin increasingly felt his arrival and the "system" were planned. It felt like a game with restrictions. He'd mentally called the unknown entity several times but got no reply, knowing deep down he'd likely never get one. Not even this world's strongest could query entities that yanked souls across worlds, granting physics-ignoring "systems."
Rested, he called Third and Fifth to sit opposite. They obeyed. The process went smoothly. Kenshin guided their minds expertly, taking initiative. Their submissive minds offered no resistance, so in half an hour, he transmitted the full technique info—the rest was up to them.
"Thanks, Father!" Third and Fifth said in sync, thrilled. Natsumi's sons had been downcast, envying Aya's Sharingan-awakened ones.
Natsumi's other kids were encouraged too, hoping for Father's help.
"The best thanks is diligent training and family service. Don't rely only on me. Without your effort matching study requirements, I can't help."
Kenshin motivated them relentlessly, tuning their mindset. He didn't know how to boost born kids' talents, as later-born clearly progressed faster than elders.
