A secret revealed - Final submission

"You see, I may be fated for the lateral branch of the Hyuuga, despite my strength, little better than a servant for the main house, really." Neji said somewhat bitterly. "But I did receive a very interesting reward from the council, a bride price, if you will, for marrying your valuable womb."

Naruko and Neji locked gazes as she continued to glomp his cock, listening to him attentively.

"It wouldn't do for a Hokage's grandchild to be born a ****, after all. Very undignified. " And Naruko could hear the irony in her husband's voice. She knew exactly what Neji thought of her 'dignity' as a Kage's daughter. "So I made them promise that my children, all of my children, would be born into the main branch of the Hyuuga."

Neji's feral grin showed far too many teeth to be even remotely kind. His dick pulsed and came like a torrent, loads upon loads of delicious warm spunk settling nicely into Naruko's stomach.

... and yet he was still hard. If anything, he got even harder, spurred by the hunger for success that is the primal instinct of all males.

With a swift and skillful motion, Neji wrapped his wife tightly and lifted her up, Naruko's pregnant belly weighing nothing at all with his prodigious strength. He placed her on the table and sheathed his mating tool on her eager pussy. Naruko's insides wrapped around him like a glove.

"Do you know what this means?!" Neji spoke louder, which for the stoic young man was practically screaming. He fucked Naruko like a hungry beast, very much unlike his usual composure. "It means I'm gonna have as many brats as I possibly can!!"

Neji increased his pace, twelve inches of man meat skillfully carving a path through Naruko tight young pussy.

"It means that, with only two pathetic daughters, that bastard Hiashi's line has failed." A victorious smile stretched on Neji's face. "While you, on the other hand, are already carrying two of my strong sons!"

Naruko wrapped her legs around her husband, and he moved his hips in a frenzy. The tip of Neji's cock now knocked heavily against his wife's cervix, rapidly destroying her defenses.

"It means my seed shall rule the Hyuuga. Not his. MINE! Forever and ever."

...

Then it dawned on her, the truth of her marriage. Naruko meant victory over Neji's greatest rival, the triumph of his lineage, nothing more. He didn't love her and likely never would.

Naruko should be sad, devastated or even fucking furious, knowing that to him, the man she loved with all her heart, Naruko herself would never be more than a fertile womb, and the promise of better status in the Hyuuga clan, but in truth...

She loved every second of it.

As a woman, she loved being useful to her man. She loved knowing that her womb was a useful weapon for him. She loved the assurance that, as long as she could bear children, Naruko herself would remain well-fucked and a target of his constant 'affection'.

"Mine... Mine. Mine! You are all mine!"

So, as Neji continued to devastate her pussy and grunt like a raging bull in the sack, Naruko found herself meekly responding - "Yours..."

PS: And there it is. This was the condition negotiated by Neji on chapter 7.
