Prologue

"You're leaving?" She said in complete disbelief.

"Yes. I have to I can't be here, do this job and recover."

He didn't just say that did he? He's not just going to walk away?

"It's too much. I know that everyone cares and is just trying to help but I just can't do it this way." He continued sombrely, looking at the ground.

I can't believe this is happening

"I need to take care of this myself, by myself" He continued to look at the ground, unable to bring himself to look at her. It wasn't supposed to be this hard.

"So that's it? You're just going to walk away?" Her voice cracked, her eyes glistening with unshed tears. She would not allow them to fall. Not yet.

"I have too" His voice quite, barely above a whisper. "I don't want…I just have to." He was so tired both physically and mentally from everything he'd been through lately and with the decision he'd made. The tiredness clear in his voice.

"Don't want what, Martin? What were you going to say?" Her voice raising in volume with anger she suddenly felt coursing through her. He can't just walk away! I want an explanation dammit! I at least deserve that don't I?

"Please, Sam. Please don't be mad. I don't know how to explain this to you so that you understand. Please don't make this harder for me." He begged her, his voice pleading, looking at her as he finished, for the first time since he walked through her door that evening.

"Harder for you? You're the one who's made the decision! You're the one who wants to run away! I'm just supposed to be OK with this? Wish you well on your way?" She was angry. Her unshed tears now freely flowing down her cheeks. She didn't try to hide them or stop them. She was too angry to care right now.

"I'm leaving town in the morning. I don't want anyone to look for me or follow me. Please don't look for me." There, he'd said what he'd come to say. He started for the door.

"That's it? You're done?" Disbelief once more in her voice, her anger fading. He can't just leave like this.

She started towards him, placing her hand on the door before he could open it.

"Don't go. Stay. Please Martin."

"What do you care, Sam?"

"I care. More than you know."

Their eyes met. They both suddenly realised just how close they were. Stood at an angle to each other shoulders nearly touching.

Without breaking eye contact, Sam moved so that she was stood between Martin and the door.

"Stay" she repeated.

Suddenly they both leaned in to meet the other in a fierce kiss quickly becoming very heated. Tongues duelling, hands wrapped in the others hair, all thoughts of leaving quickly left Martins head.

They moved back in to the room towards the bedroom, ripping clothing off as they went, only coming up for air when necessary.

Soon they were stood naked in her room both very hot and ready.

Martin pinned Sam against the wall eliciting a moan from her. He held her up as she wrapped her legs around his waist.

He steadied himself against the wall with one hand, whilst the other played with her breast and his mouth worked on the other, bringing her nipples up hard. Sam gasped and dug her nails hard enough in to his back to leave marks.

"Martin, need you…inside…now" She gasped her breathing hitching, revelling in the sensations running through her. The sensations Martin was causing.

He let her down, his breathing also coming in gasps, and turned her towards the bed.

They moved together setting a quick pace, both desperate for the contact, hands and lips everywhere, rediscovering each other.

It had been so long and he had missed her so much. He knew he couldn't hold out much longer but didn't want to come without her. He reached a hand down between them and began flicking her clit furiously be bring her to climax that much quicker.

Sam cried out at the extra contact and both were so close to that edge.

Three more hard strokes and she climaxed screaming his name sending him over the edge with her.

As they came down from the high, breathing hard, Martin rolled off her on to his back pulling her with him so she was lying curled in to his side, arm across his chest, legs entwined.

Like this Sam quickly felt sleep overcome her. For Martin however, sleep was the last thing on his mind.

He watched Sam as she slept. Once he was sure she was asleep, he carefully disentangled himself as not to wake her. As quietly and quickly as possible, he gathered his clothes and dressed.

Once dressed he crept back in to Sam's room and gently sat on the edge of the bed facing her.

He brushed a lock of her hair back from her face and behind her ear before leaning down and placing a quick, soft kiss on her temple.

"I'm sorry Sam. Goodbye." He whispered before he got up and walked out closing the door quietly behind him
