This story starts after Booth and Brennen's first case, not Cleo Eller, the one before that, as covered in The Parts in the Sum of the Whole. She didn't get in the cab.
This changes everything.
He pushed her against his apartment door. They hadn't stopped kissing since they climbed out of the cab together. His right hand jostled for the keys, his left leaning against the door next to Brennen. He didn't want to break their kiss, but he had to to get the door open. It pained him to do that. Booth pulled his mouth away from hers, and looked down into his right hand, not noticing the impatient look on her face. He finally got the door open, and they began to kiss again, more hungrily this time. Every time their lips separated, it was twice as intense when they finally met again. Every kiss more deep and passionate than the last.
They made their way to his bedroom, leaving a trail of clothing along the way. Booth threw her onto the bed, and climbed on top of her. They were both naked, and they were both too drunk to remember what was going to happen. He kissed down Brennen's neck, and delighted in her gasp when he entered her.
The next day Temperance awoke with a splitting headache that even hell fires would not drive away. She struggled to open her eyes, the sunlight streaming into the room was threatening to be blinding. She blinked a few times, not knowing where she was. She had awoken in someone else's bedroom. 'Shit, what have I done?' she thought to herself.
After blinking her eyes a few more times, and letting her eyes adjust to the light, she was startled into reality by a light snore beside her. She sat straight up in the bed, suddenly realizing she was not alone. Temperance held the sheet close to her chest as to avoid any more exposure. She slowly turned to look, she needed to know who's apartment this was.
She was not surprised to see Seeley Booth passed out beside her.
