Chapter 24

It had all started when he had pointed out that the milk was empty. He had made the momentous mistake to bother her with the lack of milk in their fridge - which had by the way been his fault because it had been his turn to do the grocery shopping - before her first coffee. Her reply had probably been a little too harsh, since it had managed to make him loose his peace.

As passionately as they usually loved each other, sparks had been flying then. Neither of them had wanted to give in, so things had gotten worse, one word had followed the other until doors had been thrown shut and silence had followed.

They hadn't spoken a single word with each other before they had to leave for work. At the lab they had avoided each other as good as possible, exchanging only a minimum amount of words when talking had really become inescapable.

At some time she, Grissom and Warrick had been discussing the victim's phone calls, she had actually been pretty content with herself because she had managed to hide her anger from Warrick, but then… Thermite. She just hadn't been able to swallow her comment. She of course hadn't planned this, the words had suddenly just been there and she had felt like saying them. 'Maybe some people shouldn't be together.' His expression had been priceless.

An hour later she had been sitting in the break room, wanting to eat her lunch. Still slightly furious about her comment Grissom had entered, telling her to meet him in his office in twenty minutes. He was still pissed off. But she could only grin about this, she was still angry but this whole situation started to amuse her.

So there she was now, knocking on the door of his office. He had closed the blinds and she knew that this meant 'Don't dare to bother me!'. She wasn't sure if she should bother him now, but after all, it had been him who had told her to come and see him in his office.

He didn't answer so she simply entered. He wasn't there. She sighed softly and was about to turn around and leave when she surprisedly felt him behind her. She winced, not having expected him to suddenly be so close to her. She heard how he closed the door and locked it. A cold shower ran through her when his hands grasped her hips, dragging her close to him. He was still angry, she could feel it in the way he touched her. This wasn't the gentle Grissom she was used to.

"Take it back." He told her with low voice, his lips close to her ear.

"Take what back?" She replied knowing that this made him even angrier. She knew that it was probably not the best idea to make him angry, but since he already was angry...

"That we shouldn't be together." He didn't sound that angry anymore, but somehow there was a sad tone in his voice.

She swallowed hard. "I wasn't talking about us. Remember, we have rules, there is not an 'us' when we are here."

His hands slipped up her sides and he pressed her back against his chest. She gasped when he cupped her breasts with his hands. "Damn it, I know you were talking about us." He whispered into her ear.

"What makes you so sure about that?" She asked, teasing him even more.

All of a sudden he turned her around to face him. Their gazes met in an intense struggle of emotions. They both were angry, but at the same time they wanted to give in because this whole argument really made them feel miserable. "I know you." He answered.

"Well, your comment wasn't any less personal." She tried to defend herself.

"My comment wasn't a personal one until you interpreted it as such." He let his hands travel over her back while he spoke.

"So what was I supposed to think after our argument this morning?" She couldn't think with his hand on her. Damn it, she knew what he was trying to do here.

"And what was I supposed to think?" He turned them both around so that she was facing the wall with her back.

"You said you regretted that you asked me to move in." Her voice was strong but the rest of her wasn't. She was so close to give in.

"After you told me that you'd regret that you gave up your apartment and moved in." He pushed her closer to the wall.

"Only because you," Okay what were his hands doing on her bottom? She swallowed hard, no she had to resist him. "Only because you said that you never had trouble when you were still living alone."

"Because you said you wouldn't understand how I could be so unorganized when it comes to grocery shopping." He stopped pushing her backwards when she had hit the wall, his hands now resting on her hips.

"Who forgets the milk? I mean I don't even drink milk, it's your milk so how can you forget it and then blame me?"

"I did not blame you, I only pointed out that the milk was empty." He corrected her. "You only thought I blamed you because you are always bitchy before you get your first coffee injection."

She couldn't help but smirk now. "When you know that so well, why did you expect me to act rationally in that moment?"

He shrugged. "It was worth a try." He had this puppy eyes expression now and he knew that she never could resist him then.

She chuckled and leaned against his chest. "Oh damn it Gil Grissom, how dare you to look at me like that?"

He didn't answer, instead he pinned her against the wall and kissed her passionately. All thoughts left her there. Ignoring that they were in his office, she gave in to his kisses and touches. When he pulled away from her a few minutes later she let her eyes meet his and gave him a soft smile. "I'm sorry." She whispered, so much for her plan to not be the first one to apologize.

He softly kissed her on her forehead and smiled. "So am I."

She ran her hand over his chest and winked at him, seducing him with the expression in her eyes. She knew that he was hesitating; he bit down on his bottom lip and let his eyes wander over her body.

She let her hands slip down to the waistband of his pants, smiling about the twinkle in his eyes. "You started this, now don't back out." She whispered into his ear while she slid her hands under his shirt.

He swallowed hard, obviously close to losing his self control. He considered it for a moment, then kissed her again, dragging her away from the wall.

Breathlessly he pulled away from her after a moment. "If I would have known that an argument would lead to this, I would have bugged you before your first coffee earlier."

If you wanted office sex with me, all you had to do was ask, I was ready for that ever since I came to Vegas. The words were on her tongue but her comment would have destroyed the mood, so she kept it to herself and let him help her up onto his desk. If every argument would lead to make up sex in his office then she wouldn't complain about the arguments any longer.
