A/N: So here is my story for the Conversing Harts Challenge over on the Boneyard. It was supposed to be a oneshot, but I have just been convinced to write more so there will probably be one more chapter! The song is Hurt So Good, by John Cougar Mellencamp.

Here are the rules that I had to follow as per I hart Booth:

1) Must take place on a train (remember, there's many things on a train, coach seating, sleeper cars, lounge area, dining car ect.)

2) Can be BB romance or friendship and can have as many or few of the squints as you like

3) Must contain the words 'greasy' 'crusty' and 'buff' (I just finished watching Encino Man

4) Booth is restless and gets on Brennan's nerves

5) Must be classified as fluff

Trains, Planes and ……Kissing?

"Explain to me why we have to take a train again?" Brennan said exasperatingly.

"We couldn't fly and my car's in the shop remember?" Booth replied. "Besides just relax. I love trains."

"Well at least I can work on my book for a while." She said, bringing out her laptop.

"Uh,uh." He said, snapping it shut. "No work until we get there."

"Technically writing is a hobby, not work and therefore does not fall under your 'no work' distinction."

He sighed as she opened it again.

"Fine." He muttered, moving over to the bed across from hers and reaching into his bag. He pulled out his Ipod, pressed play and leaned back on the tiny bed.

They were on their way to South Carolina, and since there were no flights available and they needed to be there immediately they hopped an overnight train. Bones had complained the entire time and he had admitted it had been difficult getting all of her equipment on the train. Plus, it turned out that it wasn't one of those nice smooth trains where it barely felt like you were moving, but a rather rickety one that lurched and stopped at various points of the journey.

But he had hoped they could spend a little time together, but clearly Bones had other ideas. He changed to the next song and grinned. He immediately began tapping his foot on the bed.

Brennan for her part, was deeply concentrated on her book. Well at least she was trying to be, but Booth's foot tapping was annoying her profusely.

"Booth? Booth, can you stop that please?"

He didn't answer and she knew by the sound emanating from his ears that he had his music up too loud. She continued to watch him, his eyes closed, tapping along to some beat, when all of the sudden he surprised her by beginning to hum.

The hum quickly turned into singing, which got full blown by the time he got to the chorus.

'Hurt so good
Come on baby, make it hurt so good
Sometimes love don't feel like it should
You make it hurt so good'

She never heard of the song before, but she had to admit that the sight of her partner singing it caused her body to tingle in places that made her blush. Clearly he didn't realize that he was singing aloud.

'Hey baby, its you
Come on, girl, now, its you
Sink your teeth right through my bones, baby

Let's see what we can do
Come on and make it hurt

Hurt so good
Come on baby, make it hurt so good
Sometimes love don't feel like it should
You make it hurt so good'

She realized the song was about sex and felt another twinge in her belly. 'Stop that.' She thought to herself. 'We are just partners.'

Suddenly his eyes shot open and he sat up, pulling the headphones out of his ears. She couldn't help but giggle at the look on his face.

"Uh…sorry.." he said, his face turning beet red. Her giggles escalated and soon she was on her side, clutching her stomach, tears running down her face.

"You think that's funny, do ya?" he growled, moving off his bed and over to her, where he began to tickle her furiously.

"No, Booth….don't…" she gasped, shaking with laughter. He stopped and unconsciously reached up and brushed her hair away from her face. Her laughter faded away as she realized how close their proximity was.

"Bones…" he said softly, his hot breath caressing her face.

"We should eat." She blurted out.

"Uh, right." He said, backing away. "Eating is good."

She got up off the bed and headed to the door with Booth. At that moment, the train lurched and she stumbled and fell back against him. Her eyes widened as she found him pressed against her and she hastily made her way out the door.

Booth followed her, muttering under his breath 'Eating is good? Real smooth, Seeley.'

They made their way down to the dining car and took a seat across from an elderly couple.

He picked up the scant menu and wished for Sid's as he so often did when he was away.

"Well it's not Sid's." she said, voicing his thoughts.

He nodded and looked down at the menu again, in search of something good. "I guess I will have a burger and fries." He said.

"Too greasy for me, I'm just going to have some pasta." She replied.

"Does that mean you aren't going to steal my fries?" he said, grinning.

She grinned back. "We'll see." She said mysteriously.

They laughed and joked their way through dinner, which wasn't half bad. They had avoided work conversations and instead talked about movies, Parker and how crusty a pie had to be in order to be considered perfect in Booth's eyes.

Finally they made their way back to the sleeper car, both feeling nervous about sleeping in such close proximity.

'Don't be silly.' Brennan thought to herself, as she changed in the bathroom. 'You have slept closer before.'

She left the bathroom room only to come face to face with a half naked Booth. 'Uh… the bathroom's all yours.'

She blushed as he brushed past her and headed into the bathroom. Who knew that underneath his suit, Booth had such well-defined musculature? What was the word Angela had used? Buff, that was it. Seeley Booth was definitely buff. She felt her cheeks turn redder and she busied herself with putting her toiletries bag back in her suitcase.

The door swung open and as he moved towards his bed, the train lurched again and he found himself stumbling forward, his hands reaching out to the closest object to steady himself. Unfortunately, the closest object turned out to be her, and they both went tumbling to the ground with a thump.

"Oof…..Booth." she said, trying to push him off of her.

"Sorry about that." He said, panting heavily. He looked down and saw her breathing heavily as well and became instantly aroused.

"Booth…I…" she trailed off, unable to stop staring into his eyes.

"Bones." He said softly, lifting one of his hands to stroke her cheek.

She shut her eyes and held back a moan as his hand caressed her cheek and then her lips. Her tongue darted out to wet her lips and she licked his finger, causing him to shudder.

His hand trailed down her chin to her neck and suddenly she felt his lips pressed against her forehead, then her eyelids, nose, cheeks and finally her lips. She moaned as he kissed her harder, his tongue making its way into her mouth.

All thoughts about whether they should be doing this or not, flew out of her head as she gripped his arms and pulled him closer.

"God, Booth." She gasped, as he kissed along her jawline, his hand moving towards her chest.

"Hmmmm…." He replied, running one of his hands through her hair. He pulled away and looked into her eyes, now a deep, dark blue. Her lips were swollen and he leaned down and sucked gently on her lower lip, causing her to moan again.

"Aren't you glad we took the train now?" he said, capturing her lips in another kiss, before she had a chance to respond.
