In Naruto: Reborn with Talent

Rei laid in bed with Kaguya in his embrace, her head resting on his chest while she gently scraped her sharp nails over his skin, causing him jolts of tingling pleasure.

Both were quite tired and sore from their night activities but still awake. Even with Rei's physique being boosted with nature energy for a few decades and him possessing a body far surpassing even Tsunade in the Sage Mode, Kaguya matched his stamina almost equally. Adding that to the fact she was on a dry spell for the better part of the millennium and her recent favorite hobby was watching Rei and one of his wives going at it...

Let's just say that Kaguya was one fiercely horny bunny.

Despite that, Rei enjoyed it. Surprisingly, Kaguya wasn't one to seek domination over her partner. She was ever so eager to bend to his whims, almost lovingly following the lead and going with the flow to get the most enjoyment out of the situation.

With Kaguya's personality, it was the most unexpected development.

Rei honestly blamed Konan for that. He had no idea how but definitely, it must be her fault. Somehow.

Rei's right hand was caressing Kaguya's silky snow-white locks while his left rested on her upper back, idly caressing her smooth skin, causing Kaguya to occasionally let out quiet sounds of appreciation.

Kaguya had to admit, she enjoyed this entirely too much. It was everything she hoped for and more. With her previous husband, sex was a chore after the initial affection waned, and even before then, it was nowhere near what she experienced just a few moments ago.

Some of the positions and places where they did it... It actually made her feel quite embarrassed! In a good way though. She would go for a repeat instantly!

Kaguya's eyes silently morphed from Rinne-Sharingan to Byakugan, hers was a perfect one so no veins bulging out around her eyes, leaving only perfect Lavender irises to appear. This way she didn't even need to turn her head to see all of her lover and it made her feel giddy on the inside.

'Mine.' She thought, almost purringly, subconsciously biting her lower lip. She wanted to melt and swoon when she saw Rei's content expression with his eyes closed and a small smile etched on his lips. It almost gave her strength to continue... before her sore body reminded her that it had enough for the time being.

Rei didn't let any outward sign but he could feel her overly eager heated gaze all over his body quite clearly and almost involuntarily shuddered. 'And the mystery of from whom did the Hyuuga clan inherited their kinkiness and voyeurism is solved.' He wryly thought.

Frankly, Kaguya reminded him of Hinata with her behavior. If it was only in certain aspects, it would have been fine but what he was most afraid of were the first signs of the sickness known as yanderism.

Since she got out of the seal, Kaguya just oozed this weird mix of fanatical possessiveness and timid submissiveness to the focus of her obsession that Rei always associated with the creepy Hyuuga Heiress. It was exhilarating and worrying in the same measure to be said focus.

During the first hours since she was out, he played it off as his mind playing tricks on him. After all, they were at the start of a very heated sex marathon and there was not much place for thoughts as their carnal desires and instincts took over.

But after five days of nonstop sex, Rei started to notice how she clung to him, how she soaked every bit of attention he was willing to give her, how she desperately tried to keep his interest on her rather than ending their lovemaking... he decided the first signs of her forming dependency on him and decided to show her the affection she so desired. If only to prevent her from going full yandere on him later on.

Rei did love her. It is quite hard to have someone basically live in your mind for months on end and not form at least a cordial relationship when you spend hours per day talking to said person and feel her presence almost constantly. Rei could admit... this solution of his with forming a mental connection between them did not work exactly as he hoped for. In fact, it backfired as they both formed feelings for each other without even realizing it. But... at least it backfired in a good way.

Kaguya was a very sweet and loving woman that would literally do anything for the person she loved. The only possible issue was her budding yandere tendencies but Rei wasn't too worried about it.

After all, Kaguya had an alright relationship with his other wives so that would not be a problem. She had nothing but the utmost respect for Konan and grudgingly tolerated even Ringo who was her least favorite member of the pack.

After the hundredth day, Rei decided to hell with it and started actively using nature energy to finally wear Kaguya down to her current state. It took him fifty days and he realized that... both of them were basically monsters at this point in time.

150 days of sex without water, food, or rest, their bodies only passively powered by the thick nature energy in the surroundings. And while he did feel a bit tired and was definitely sore, he was neither thirsty nor hungry. Rei never realized this. He never went without water or food for more than a few days. He never had any need to do that.

Nevertheless, they had all the time in the world since Kaguya created this dimension full of nature energy and containing just a single king-sized bed.

The irony of her doing in seconds what took Rei numerous months of research and a happy coincidence to accomplish when he was making his own dimension, was not lost on him... Damn the Rinnegan was a hax!

But now that he saw how she did it, Rei had ideas on how to replicate the feat so not all was lost...

The biggest advantage of this dimension was that time flowed extremely slowly. Hundred and fifty days inside was fifteen hours outside. Kaguya was simply the ultimate cheat worthy of the term 'Goddess' now that she had most of her power available to her.

But her biggest usefulness was not what she could do but how she did it. Kaguya did not do some incomprehensible hocus pocus. What she did was a technique based on chakra manipulation done subconsciously. Which meant, it was replicable.

This meant Rei could eventually find out how she did it and learn how to do it himself. Sure, it would take him a very long time to replicate what is basically a power of a God, but it was not impossible. After all, all she did was manipulate chakra to a degree not yet attempted by anyone else.

And while Kaguya didn't pay her powers much mind since they came naturally to her, Rei had his sensing powers going full throttle whenever she was using them. Data was important!

If Rei didn't miss his other women, he would probably spend a lot longer here with Kaguya and he would definitely come here again with all of his lovers for a vacation but it was time to return. It took a great deal of willpower from Rei to find this determination.

But… a little bit more wouldn't hurt, would it?

Her soft body and pleading eyes were definitely an enticement enough to stay but the little minx was actually learning how to excite him! Twenty days ago, she would definitely not try pushing her chest into his body nor would she put her thigh over his abdomen, nearing his crotch, close enough for it to be teasing.

Rei could feel himself getting hard again and if he didn't put a stop to this, he was fully aware they would start another days-long session.

Putting his left hand across her back on her shoulder, Rei suddenly pulled her over, making her roll over and land on her back next to him on the bed. He instantly flipped his body above her and before she could whinily protest, his lips sealed hers in a deep kiss while his right hand gently caressed her cheek.

Pulling away, Rei softly smiled and spoke, "Let me check your seals. It has been almost half a year already."

Hearing that, Kaguya looked at him in silent, unwilling shock for a while before she pouted. She wanted to continue kissing, touching, and...

But she rolled over and laid on her belly with a huff and great reluctance visible in her body language as she buried her face into the pillow.

Rei smirked and sat on her lower back, gently putting his hands on her tense shoulders while hearing her breath slightly hitch as she felt it.

'Now then.... It was a long time since I used chakra to pleasure a woman but a small massage while I am checking the seal won't hurt, no?'
