The Baby Daddy In The Partnership.

A/N: So we all know what happened in the past BB kiss scene of The Parts In The Sum Of The Whole. But what if BB actually slept together and it still ended up going sour like it did in the episode, apart from the fact they didn't do the horizontal mambo. This explores that side to it. :P Hope you like! :)

Chapter One: The Mistake In The Bed.

As soon as Brennan breaks the kiss between the two of them and jumps into the cab.

"Are you coming?"

"Hell yes I am."

Booth runs and jumps into the cab and gives the cabbie his address. He turns back to Brennan who pulls his head back to hers and kisses him passionately. They arrive at his ten minutes later and they race upstairs, breaking the laws of physics until the early hours of the morning.

Brennan wakes during the night, cuddled against Booth's naked chest and starts to freak out. I can't do this. I felt so much when he kissed me and when we slept together? I'm not ready for this. I can't go through with this. We both know this is more than just sex. I can't commit to this kind of relationship. I have to get out of here.

Brennan carefully slips out of Booth's bed, dresses and calls a cab.

The next day, Caroline tells Booth he needs to re-hire Brennan and it all goes south from there. They fight and it culminates at the point that Brennan hits Booth. They don't talk again after that. Not even when Brennan discovers she is pregnant a month and a half later.

A/N: I know this was a short one, but this was basically a set up for the rest of the story. Please tell me what you think. :)
:D
