Yes, he impregnates her

Sasuke's grip tightened on Naruko's hips as he rammed into her with a ferocity that made the bed frame rattle, his cock pummeling her pussy as if it were a battlefield to conquer. Her eyes rolled back in her head, and she could only manage a series of breathless, high-pitched moans as she succumbed to the overwhelming pleasure. Her cheeks were flushed a deep red, and her mouth hung open in a silent scream, the image of pure ecstasy known as ahegao etched upon her features. The sound of their bodies colliding filled the room, a cacophony of passion that grew more intense with every stroke. Suddenly, he pulled out, and she felt the loss of his thickness, only to be filled once more as he flipped her onto her stomach and entered her from behind. His hips slapped against her ass, the sound echoing through the room like a drumbeat that matched the rhythm of their hearts. He reached around, his hand wrapping around her throat as he whispered, "You're mine, now and forever." With a final, brutal thrust, he released his load deep within her, filling her with his potent seed. As he withdrew, he watched as the proof of their union began to dribble out, a symbol of the new life they had created. His hand slid down to her stomach, pressing gently as he murmured, "You're going to be a good mother to our child." Naruko's eyes glazed over with satisfaction, the reality of her impregnation setting in, sealing her fate as an Uchiha breeding tool, a role she now craved with every fiber of her being.

Naruko lay there, panting and trembling with the aftershocks of her orgasm, the feeling of Sasuke's warmth still deep inside her. As she felt the sticky evidence of his claim seep out of her, she knew that she had truly become a woman. The realization that she could never be a boy again, not after bearing the children of such a powerful man, brought a strange mix of sadness and excitement. But as she looked up and saw the smug smile on Sasuke's face as he gazed down at her and her mother, she knew that she had gained something far more precious than the illusion of gender. She had become an instrument of the Uchiha legacy, a vessel for the continuation of their line, and that was all she ever truly wanted. The thought of carrying his child, of feeling it grow within her, filled her with an overwhelming sense of purpose and belonging. Sasuke's eyes gleamed with satisfaction as he took in the sight of the two women he had conquered and impregnated, their bodies marked with the proof of his virility. He knew that their combined power would produce offspring that would be the envy of the entire shinobi world. As he leaned down to kiss her forehead, a gentle gesture amidst the storm of passion, she closed her eyes and whispered, "Thank you, Daddy," sealing her acceptance of her new role. With their fates now irrevocably intertwined, Sasuke looked forward to the future, eager to see what twisted paths their love and lust would lead them down.
