Even in the strongest relationships there are moments of doubt, but Naruko doesn't let Shikamaru forget who she wants. Established relationship.
"Good morning, Nara-san. Here is your mission re…" The nin trailed off limply, eyes glued to something behind Shikamaru.
The Nara blinked groggily, leaning heavily against the doorframe of his apartment, waiting for him to finish. The man's face flushed and his mouth hung ajar, prompting Shikamaru to raise an eyebrow. After another minute passed and the messenger made no sign of continuing, other than a low gurgling noise, he glanced over his shoulder to figure out what the hell was so interesting. Naruko, half asleep as well, had stumbled through his living room to the kitchen where she was boiling their breakfast tea, still wearing the see-through nightie from the night before. And nothing else.
He jerked upright, looking back and forth between the Nin and the blonde, glowering.
"Oi. Naruko." Shikamaru pulled off his shirt and threw it at his lover. "Clothes."
She caught it with her face, complaining incoherently as she obediently forced herself into it. It covered the tiny nightie easily but barely reached mid-thigh.
He turned back to face the messenger Nin, who had the decency to look mortified at ogling his superior's woman. Unamused, Shikamaru prompted, "As you were saying?"
"Uh, right, sorry. Um, your mission report, sir. And the Hokage wishes to speak with you before you head off."
"Is that all?" He yawned, taking the scroll when the Nin nodded. "Fine, tell the Hokage I'll see her at noon."
The man hurried away but not before Shikamaru called out blandly, "Oh, and if you stare at my girlfriend like that again, I'll have you reprimanded. Understand?"
"Y-yes, sir."
"Good. Now beat it." Shikamaru yawned again, shutting the door behind him as he made his way to the kitchen. Naruko chewed lethargically on a piece of toast, head propped up on her hand. He sat down next to her at the small table, taking a sip of the tea she poured him. "And as for you, what's the big idea, walking around dressed like?"
"You weren't complaining last night," she said with a sleepy chuckle, eyes still shut.
He frowned, unable to argue against that. "Yes, but not when people are around to see you."
She shrugged, leaning back in her chair to stretch. Observing her appreciatively, he felt a bit smug at how good she looked in his shirt. "Well, at least he has a stimulating story to share with his friends."
"I'll have them all on cleaning duty for a month," he grumbled, reaching over to pull her into his lap. She giggled and complied, wrapping her arms around his neck as he did the same to her waist.
"That seems like an abuse of power, Shikamaru," she hummed, playing with his hair. She loved it when he let it down.
He huffed, resting his head on her shoulder, feeling the tension leave his body as she dragged her fingers gently across his scalp. "He's lucky I just woke up, I wouldn't have been so lenient if I'd been fully awake."
"So possessive," Naruko breathed out indulgently, lifting his chin to press soft kisses to his face. "You know you're the only one I want."
Shikamaru curled further into her, tightening his grip. "I know."
He also knew how lucky he was to have her and the other man's admiring gaze had only driven home how easily she could replace him if she so desired it. Standing, he picked her up and carried her out into the living room.
A yelp left her lips and she clung to his neck to stabilize herself. "Shi-Shikamaru?!"
He kept walking, heading to his room. "We're going back to bed."
"Shikamaru!" She managed before he sealed his mouth on hers, ravenous. Panting, she broke away and had to dodge his attempts to continue. "What's gotten into you?! What about your meeting?!"
One of his hands gripped her hair lightly and he spoke against her lips, "If Kakashi can be late, so can I."
Feeling the tension in his shoulders and seeing the uncertainty in his face, Naruko's eyes soften and the words in her throat faded away. She pressed forward, sighing into his mouth. "Fine," she moaned, letting him slip off his shirt and the nightie, "just this once."
These two, I swear. They really are perfect for each other. As always, comments are lifeblood to writers.
