Hallway

He moved lower, kissing along her collarbone, his hands moving to the hem of her shirt, pulling it up ever so slightly to expose more of her skin. 

Kushina shivered, her body betraying her as her fingers gripped his shoulders tightly, pulling him closer instead of pushing him away.

Naruto smirked against her skin, knowing that he had already won. He whispered against her throat, "I'll take care of you, Kaa-chan. Let me give you what you've been missing all this time."

Kushina let out a soft moan, her body trembling in his arms. She knew making out with her own son was wrong, but the way he touched her, the way his lips felt to her—it was impossible to resist. She was slowly losing herself in the heat of the moment, and Naruto could feel it.

[Ding!]

Naruto ignored the system's notification completely as his hands slid lower, teasing the waistband of her pants, his lips continuing to explore the soft yet tasty skin of her neck and shoulders. 

Kushina's breath quickened, her body pressing further against him, feeling her boobs pressing against his hard chest. She sought his body, desperate for more contact.

Naruto's smirk grew as he pulled her back into a deep, hungry kiss, his hands roamed wildly on her body after letting go of all his inhibitions.

He could feel Kushina giving in completely, her body melting into his as her inhibitions faded away.

He pressed her against the wall, pinning her there as he deepened the kiss, his hands exploring every inch of her body. Kushina's moans grew louder, her breath coming in short, ragged bursts as she clung to him, her nails digging into his back.

Naruto knew he had won.

He broke the kiss, his lips brushing against her ear as he whispered, "You're mine now, Kaa-chan."

Kushina's eyes fluttered open, her face flushed, her body trembling from the intensity of the moment. She could no longer deny what was happening between them, and for the first time, she didn't want to. She wanted more, as she closed her eyes and moved towards him.

Just as Naruto was about to take things further, they heard the sound of gates opening,

"Kaa-chan! I'm home." Mitsuki's voice sounded in the house.

Kushina's eyes flew open in shock, and clarity returned to her as she looked at Naruto, then at herself, and saw that she was a hot and wet mess currently.

She sprinted toward the bathroom before Naruto could even say anything. Her face flushed with a mixture of shame and guilt at what she had done. Yet there was desire hidden beneath her glazed eyes.

She barely glanced at Naruto before disappearing behind the bathroom door, shutting it close.

Naruto stood there for a moment, taking rough breaths due to the intensity of the moment that he just had with his mother.

His lips were still wet from Kushina's saliva, he licked them clean with a smile on his face. He could hear Kushina frantically trying to compose herself in the bathroom, the sound of water running as she splashed her face.

But his thoughts were immediately pulled back to Mitsuki. She was in the house now. He quickly ran a hand through his hair and straightened his clothes. 

His heart pounded in his chest as he made plans for what to do next. He headed towards the door, his movements quick and calm.

He didn't want Mitsuki to suspect anything yet. As he stepped into the hallway, he saw her coming into view, her red hair a perfect march for their mother's. And her face lit up with happiness after seeing him.

"Ni-chan!" Mitsuki beamed as she approached him, throwing her arms around him in a familiar hug. "You've been so busy training lately, I haven't seen you since this morn-"

Her face turned bright red at the mention of this morning. Remembering what she had done inside her room with him.

Naruto returned the hug as he chuckled softly hearing her pause at the mention of morning, "What about morning hmm?" He asked in a teasing voice while hugging her.

"Ugh, don't tease me Ni-chan." She softly hit his chest in protest as Naruto laughed, he patted her soft and supple ass softly, "Alright enough playing around, go and change into comfortable clothes."

Mitsuki's face turned pink as she felt Naruto's hand on her ass, "Mouuu, baka! What if mom saw us like this?" She hurriedly ran away as she felt shy seeing him and the fear of their mother finding out about them.

Naruto watched with a smile as he finally managed to send her away from the dining room as he knew it would be problematic to explain the events on the spot.

'That ass…' he thought to himself with a smile, 'Let's see what I can do with her after dinner.

He thought about it as he walked back into the dining room, he could still hear the water splashing in the bathroom as Kushina bathed inside. The smell of their bodies lingered in the room, making the atmosphere intense.

He smiled and shook his head, "Well, I can at least make food today to show my appreciation to the two of them, even if the old Naruto is not here, I can take care of them in his place keke."

He stepped into the kitchen with a smirk on his face. The kitchen seemed familiar yet unfamiliar to him as he saw all the species and vegetables lined up neatly.

"Now, what should I make?" he thought to himself as he moved toward the kitchen counter, looking to see what was inside the kitchen.

"Well, might as well keep it simple," Naruto thought, reaching for a few ingredients. He decided to make a quick stir-fried ramen dish—something good enough to fill their stomachs as Mitsuki particularly likes Ramen.

He grabbed a handful of vegetables, slicing them with practiced ease as he had to make his own food in his previous life since he was an orphan.

He heated up some water for the ramen as his thoughts drifted back to his encounter inside the hallway with Mitsuki.
