Chapter 1

That morning started like any other.

Castiel was the first awake, as always, and he was enveloped in Sam's arms. He untangled himself, sitting on the edge of the bed and rubbing his face with his hands. Careful not to awaken his boyfriend, he padded over to the grand bathroom, not locking the door behind him – Sam hated it.

One glance in the mirror showed him what a wreck he looked like. His dark hair was matted and sticking up, most likely jelled with Sam's sweat, and there was a line of marks made by fingernails down his right arm; Sam had broken the skin.

The hot water of the waterfall-shower was a beautiful release. The tension melted from his shoulders, and he barely noticed the stinging of soap in his eyes.

He turned around at the sound of the door opening, and saw a bright smile break across Sam's face.

Slightly disappointed at having to cut his shower short, but knowing it would be what Sam wanted, he stopped the water and swung open the glass door. 'Morning, Sammy.' He figured the pet name would be alright – his lover seemed in a good enough mood.

'You look perfect,' he strolled over, planting a sweet kiss on Castiel's forehead; it wasn't difficult – Sam was a head taller.

'Why thank you,' Cas said with a smile, reaching around him and unhooking a towel. 'Why don't I go make us some coffee?'

'I was kind of liking the shower idea,' Sam said, and he ran a hand through his wet hair.

Cas swallowed. 'Not now, Sammy.'

Sam had proceeded to trace a finger down Cas's chest, but now he pushed him away. 'Fine. I've got to get to the airport anyway, I'm going to Philadelphia.'

'What? Why?' Cas said in surprise.

'Business trip, I told you yesterday.'

Cas bit back a "No you didn't", pushing past him and going back to the bedroom. 'Wait a minute? Weren't you going to that fundraiser tonight?'

'Yeah. Take my invite,' Sam called back, 'it would be pointless to waste the free wine.'

Castiel sighed. He wasn't going to bother arguing – he'd show face if he could conjure up any interest later, but in truth, he'd rather stay at home and catch up on the week's TV. He pulled on a pair of black skinny jeans and a white shirt and took a deep breath; a couple of hours and Sam would be gone.

'I'm gonna go for a walk,' he said, poking his head around the bathroom door.

'You kidding me?' Sam snapped, 'I'm leaving in an hour, you can't just clear off.'

'Why not? I'll be back before you leave.'

Sam turned around, putting down his razor and glaring at him. Cas looked down, focusing on Sam's chiselled abdomen and the slight tense of the muscles as he stood up more straight. 'You know what, Cas, you can just fuck off. It's not like I need you to drive me to the airport or something.'

Cas had to stop himself from spitting out a hundred retorts. Clearly, this business trip was about something important, if Sam was already stressing out.

'I'm sorry Sammy. I want to stay here with you, I was just being stupid.'

'Just get out, I can't be fucked with you right now.'

Really? You didn't seem to think that ten minutes ago. You didn't seem to think that when you were fucking me last night. You know what, you're the one that can fuck off – I don't need you either.

Of course Cas didn't say any of these things, instead putting on a pair of pointed shoes and letting himself out of the apartment without so much as a goodbye.

He started to feel guilty halfway towards the lift, but his desire for fresh air beat his desire to beg forgiveness from Sam.

Once out in the open air, he instantly wished that he had brought a jacket with him. It was cold in Boston winters, and, desperate to get back indoors, he made a beeline for the church in the park opposite his apartment block.

It was slightly warmer inside, thankfully, and he slunk into a pew in the back row, even though the place was completely empty.

He wondered to himself what he would say to God if he was listening. 'Why didn't you stop me having that row with Gabriel?' he said aloud. 'And why couldn't you have made Sam a bit less... uptight?'

There was a movement to his right and he flinched as a man stepped out of the shadows with his hands up.

'Sorry, I'll just leave you to your thoughts.'

'Shit, sorry, I didn't realise someone else was here,' Cas said, not even caring that he was swearing in a church. He was more focused on the fact that the man was tall and wearing a shirt that showed off every toned muscle. His eyes were green and piercing.

'Who's Sam?'

'My er... my brother,' Castiel swallowed, wishing that he could vanish into thin air. Apart from Sam, he couldn't remember any man every scrutinising him so intently.

'Shame,' the guy said with a knowing look, 'I was hoping he was your boyfriend. At least then I'd be able to fight it out for you.'

Cas's mouth turned dry. 'You do realise we're in a church?' he hissed.

'Then let's not be,' he smiled, 'call me.'

He scrawled his number on a sheet of paper and handed it to Cas.

'I will,' Cas said, trying to restore air into his lungs. He exited the church as quickly as he could, not looking back. Sam's face swam into his mind, and with a heavy sigh he screwed up the piece of paper, dropping it into the nearest trashcan.

Next chapter will be better, I promise!

Please spare a minute to review...
