Tony drummed his fingers across his desk again and reclined in his chair, glancing across the room towards Ziva's desk. She was tapping away at her keyboard, but as soon as she felt DiNozzo's eyes on her she looked up, her expression teetering between mildly annoyed and slightly amused. "What do you want, Tony?" She asked pointedly.

DiNozzo smacked his lips, turned on his most flirtatious tone, and said, "Valentine's Day is coming up. You have plans yet, Ziva?"

The young Israli officer gave him a puzzled look and echoed, "Valentine's Day? What is that?"

After a moment of initial shock, Tony grinned as he realized he could definitely use her naïveté to his advantage. "Why, Ms. David," he purred, "It's only the most important of all holidays! It's the day of love!"

Ziva laughed at the way he waggled his eyebrows, then smirked and asked, "Love as in McGee and Abby or love as in McGee and you?"

Both winced as they remembered the McAbby make out session stumbled upon in the parking lot the night before, and Tony was suddenly very aware of the fact that they'd left together and neither had shown up for work yet. He tried very hard not to imagine what they might be busy with.

"Well, both, I guess," he decided after a moment. He moved to sit on the edge of his desk, and Ziva meandered over to join him.

"Well, Tony, I wonder," she said said slowly, "how one is to determine the difference between a Valentine's greeting meant in brotherly love, and one fueled by true flirtation."

As her voice deepened, Tony cleared his throat and answered roughly, "It"s all about the body language."

"So, what would a gesture like this convey?" She asked, eyes blazing as she placed a small hand gently on his shoulder.

"A, uh, hand on the shoulder says 'friends'," Tony stammered. He was struggling to maintain his cool composure with the way she was looking at him, as if she wanted him as badly as he wanted her right now.

"And this?"

Her hand moved to his knee and he whispered, "That one's 'Let's be more than friends.'"

As Ziva leaned her body into Tony's, her breath hot and sweet against his neck, she trailed her fingers up his thigh and whispered, "And this one?"

"That one should stay out of the office, David," Gibbs snapped; the two younger agents jumped about a mile, blushing furiously as their boss delivered a well-deserved head slap to each.

"Grab your gear," he instructed, then looked around briefly before scowling and adding, "Where the hell's McGee?"
