So, I had this idea in my head and I just had to put it out here and let you guys decide if you wanna read more. It's different from anything I've written, so let me know if you like how it's going. I know it looks bad at the beginning, but it'll be B&B eventually:)

Disclaimer: Bones belongs to Fox.

Booth and Brennan were in the middle of a mind blowing encounter. It was difficult for either of them to explain how they'd gotten to that point. One minute they had been arguing and the next they were kissing. His body ached for her and he hadn't stopped things before they got to this point.

His hands were currently busy unclasping her bra. As soon as the bra hit the floor, he had one nipple in his mouth and the other between his thumb and forefinger. After a few minutes he switched his ministrations as Brennan ran a hand through his short hair. She didn't care about being pressed up against the side of the SUV in the middle of nowhere; she only cared that she was with him. It had taken her so long to admit her feelings to herself.

His lips made their way back to hers, their tongues dueling in their mouths. Brennan pulled his FBI t-shirt over his head, her hands mapping his muscular torso. She quickly undid his belt buckle, lowering his jeans and boxers to pool at his ankles. She grabbed his rock hard cock and gave it a few strokes, causing them both to moan. His lips were still on hers as his hand caressed one thigh, making upward progress underneath her skirt. He pushed her panties to the side and inserted one finger inside her; he deepened the kiss further when he felt the wetness and hotness of her core.

Her skirt was bunched at her waist as he entered her in one quick thrust, staying still for a few seconds, enjoying the feel before pulling out slowly.

She met him thrust for thrust as their rhythm increased. It wasn't making love; they both knew that, yet they still felt the connection.

Her orgasm brought his own and they rested their weights against the car as they tried to catch their breaths. Their bubble burst when his cell phone rang. Brennan had been around him long enough to know whose ring tone it was. Reality slapped them both in the face, hard. Brennan moved away from him, picking up her discarded clothing as Booth pulled his jeans and boxers up.

He answered the incoming call, already feeling guilty. "No, I'm…working." He felt horrible for the lie he had just told his girlfriend. He couldn't believe how much he'd messed up. He had not only cheated on his girlfriend, but he had just had a cheap encounter with Brennan…his Bones. He'd really messed up and he knew it. "Yeah, see you later." The guilt he felt grew when he heard the 'I love you' his girlfriend Mary gave him through the phone.

Brennan was dressed and seated on the passenger seat of the SUV by the time he finished his phone conversation. He walked around the SUV to the driver's side as he put his t-shirt back on. He started the car and drove, the uncomfortable silence killing them both on the inside.

Booth parked the SUV in front of her apartment building without saying a word. She made a move to exit the vehicle, but he held her hand.

"Bones?" She turned to face him. "I'm sorry. We shouldn't have…" Brennan knew it was irrational to feel her heart breaking, but it felt that way. She could have had him… all of him, but she'd said no. Now that she knew what it was like to have him, even that short lived moment, she knew it would be hard to see him go home to his girlfriend.

Rebuilding up her walls she said, "It's okay, Booth. I understand you have someone waiting for you." There was a short pause where she fought with all her might not to cry. "I know you pride yourself on being faithful and I won't make it hard for you." She had to bite on her lower lip for a second to keep from crying. "We're partners and we shouldn't have crossed that line." As much as he wanted to, he didn't say anything. "I'll see you at work." She said before exiting the vehicle.

"Yeah?" He asked barely audibly as Brennan closed the car door after herself.

Brennan entered her apartment and headed straight to her bathroom. She got in the shower and stood under the hot water. She wasn't trying to wash off what had happened. It had been something wonderful for her, but she knew it shouldn't have happened like that. He was with someone else and she couldn't do that to him. She couldn't knock on his door now and tell him she wanted them. That she was in love with him.

B&B

Booth entered his apartment and went straight for a shower. He didn't want to wash off what had happened with Brennan. He'd always have that burned on his skin; he would always remember it.

His eyes were closed as he lathered up and allowed the water to rinse the soap off his body. He felt arms wrap around him.

"Mmm, hello." She kissed his shoulder and he instantly pulled away.

"I'm really tired." He shut the water off and exited the shower. He knew it wasn't fair to her, but he just couldn't do it. He didn't think he'd ever be able to be intimate with her after what he had shared with Brennan. Mary was left dumfounded in the shower, instantly knowing something was wrong with Booth.

Booth was in bed when Mary entered the room. He used his sniper skills and pretended to be asleep. She slipped under the covers next to him and turned away from him. Booth opened his eyes and stared at nothing and thought about what had happened.

B&B

Two weeks later

The partners hadn't worked a case together since their encounter. They had felt that it had served them right to be separated for a while.

Booth drove them to their suspect's house and they seemed to be fine…but only on the outside. They weren't their usual self around each other and it was detrimental to making the arrest.

Booth was shot on the chest, instantly falling. Brennan took his weapon and fired at the suspect, but he was quicker and shot her first.

Brennan only had a flesh wound on her arm and was okay. Booth was taken to the hospital and the suspect was taken into custody.

Mary was in Booth's room the entire time he was kept in the hospital. It hadn't been such a bad injury and Booth would be out in a few days. Brennan had only seen him when the others had and she hadn't pushed to be allowed more time. She knew she didn't have the same rights as his girlfriend. She was just his…partner.

B&B

Three weeks later

Brennan was in her office's bathroom, staring at herself in the mirror. How am I going to tell him? She thought. She'd done five pregnancy tests and they'd all come back positive. She was pregnant. She was going to have Booth's child and as much as she didn't want to put him on the spot, she knew he deserved to know. He was a good father and regardless of what happened between them, their child deserved to know his father. Booth was a good father.

Brennan left her office after a lot of thought and was on her way to the forensics platform. She had called Booth, telling him to drop by the lab because she needed to tell him something important. She was going to give him the news. She didn't know how he'd take it. They hadn't seen or talked much after that day. Before she reached the platform she saw him enter the lab. She mustered up all her confidence and strode towards him.

"Hey, Bones." Well, at least he's calling me Bones. "What's so important?"

"Can we go into my office?" She knew she was stalling.

"I'm on the run. What is it?" He didn't trust himself to be alone with her. He didn't' want them to have another cheap encounter. He wanted to be able to offer her more.

"I need to tell you that I'm pre…" Brennan was cut off by Mary entering the lab.

"Baby, since you told me you were stopping by the lab and I was close by, I didn't want to wait to give you the news." She touched his arm and smiled. "I'm pregnant. We're having a baby!" She hugged him and Brennan felt like the air in her lungs rush out of her.

"Dr. B!" Hodgins called Brennan.

"I have to go. Congratulations." She told him weakly before heading towards the forensics platform where her presence was needed. Booth stared after her for a few seconds, wondering what it was she had wanted to tell him. Mary kissed him on the cheek causing him to return his focus on her.

So, do you like it? Is Booth's girlfriend really pregnant? What will Bones do?...

Review and let me know if there's interest for me to continue on this one.
