Ok, here's the idea : a series of one shots inspired by scientific theories, laws or techniques. All revolving about B&B, some more fluffy, some more steamy. (That's how my wicked mind works.)

Let's start with an easy one.

Newton's First Law of Motion:

An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

"Come on, Booth. Having fantasies is nothing to be ashamed of! It is quite normal for humans to visualize their desires, sexual or not! I don't understand why you're making such a fuss about it."

They walked through the empty lab. They were just coming from the diner, and now she had something to pick in her office before going home. She threw a sideway glance at Booth, who looked flustered and uncomfortable. A small grin stretched her lips. It was just too easy.

"Sincerely, I don't understand why you have such a reluctance to talk about fantasies with me. We've known each other for years!"

Entering her office, she began searching for the file she needed.

"You want to talk about fantasies Bones? Ok, let's talk about them."

His low and rough voice made her turn around to look at him. His eyes were darker than usual, and he was looking at her so intensely… She shivered. What the hell had she gotten her into?

"How about I tell you one of mine, Bones?"

He slowly walked towards her, stopping inches from her body. She could feel the heat radiating off of him, his breath on her cheek… Well, now that she had pushed him there, she couldn't really say she didn't want to hear it, could she? She was the one saying it was perfectly normal…

"Go on."

He walked around her, placing himself just behind her. His lips brushed against her ear. God, when had she lost control of this conversation?

"It involves you, this desk, and the ridiculously short skirt you're wearing today," he whispered in her ear.

She gasped.

"Yes, Bones. You are in your office, standing up and reading a file. I close the door, walk in the room, but you don't notice me because you're too concentrated on your work. I come behind you, and place my hands on your hips."

In perfect synchronization with his voice, she felt two large and warm hands cover her hips, setting her on fire. She was now holding her breath, worried that he would stop his narration.

But she shouldn't have worried, because once she had pushed him enough to get him started, he couldn't stop. Words were flowing from his imagination directly to his mouth.

"You don't move anymore, you're just waiting for me to take care of you, because you know what I have in mind. Deep down, you know I'm here to give you a breathtaking, earth-shattering orgasm. And you want that so much, don't you?"

Oh yes, I do. But only from you, Booth.

"I turn you around, and you're now facing me."

She didn't even need him to guide her this time. She willingly turned to face him, suddenly electrified by the expression in his eyes.

"I am hypnotized by your big blue eyes, your pupils are so dilated… But I don't forget why I came here. Slowly, I move you towards your desk, and now you're trapped between it and me. I see the goose bumps on your skin, and it's such a turn on to know you want that much what is coming…"

Now he was murmuring his story in her ear, holding her by the hips. Heat started pooling between her legs and her breathing was more uneven.

"You lie down on your desk without me having to ask. But you have to be patient… Good things come to those who can wait. Slowly, I hike up your skirt on your waist. This skirt is always, always driving me crazy with desire. It is so short and hugs your beautiful ass perfectly."

One of his hand went down her thigh to the hem of her skirt. To be quite honest, she knew this skirt was short, but she also knew how Booth looks at her when she wears it. And secretly, she loved those appreciative glances from him…

Now his fingers were going under the fabric, caressing her thigh without actually lifting the skirt. Fuck, yes! Please, do it, push me against the desk, hike up that skirt!

"I'm caressing the inside of your thighs, but suddenly I hear you moan. How can I not give you what you want when I hear this sexy sound coming out of your mouth? I push your underwear aside and lower my head to your wet pussy. I can smell your arousal, and it's making my head spin. Do you have any idea what you're doing to me?"

She was absolutely going to die. This was so hot, so exactly what she wanted him to do… And to know he was imagining her this way was getting her even more excited. She was feeling her underwear becoming wet, her clit was throbbing with need…

"With my tongue I trace a path from the bottom of your pussy up to the underside of your clit. You are whimpering, you want more than this. But I already told you, you gotta be patient… Now I'm pushing my tongue inside of you, fucking you with it. You really taste incredible, it's addictive… But I think now you have waited enough. I close my lips around your bud and suck it, using my tongue at the same time to play with it."

She really couldn't take it anymore, he was making her crazy. She grabbed his shirt and pulled him towards her, crashing her lips on his.

Yes. This is a fantasy coming true.

His firm lips were moving on hers while he was pressing her whole body against him. She could feel his erection pressing against her thigh, making her wish they had a lot less clothes on. His tongue passed through her lips, exploring every corner of her mouth, making her knees buckle. It was a hot, wet, mind-blowing kiss.

They devoured each other for a while before separating, her forehead resting against him, eyes closed, both panting.

Wow.

"How about this stops being a fantasy and becomes a memory?"

So? Liked it? Hated it? Let me know if it is something worth continuing… And if you have any suggestions, don't hesitate! I would love to hear from you...
