Abby's heart was beating loudly and she feared that Sam might notice it. She had no idea that he indeed was able to hear the rhythmic pounding of her heart against her ribcage as she stepped a little closer to him.

Keeping their eyes locked, Abby stood in front of him and forgot what she had wanted to say. She was sure that she wanted to tell him something but the words had already slipped her mind.

She was powerless; all she could do was keep looking at him silently.

Sam was trying to figure out what was on her mind and failed. He wasn't able to see through her. This was new to him.

He had always been capable of figuring people out and the fact that his mate seemed to be the only person who was immune against his abilities was frustrating.

He couldn't see what Abby was up to and for the first time in his entire life he felt helpless.

Once again he realized what his brother must have gone through and why he had been so lost and confused when he met Carmen.

Apparently, it was supposed to be that way.

Abby noticed a glint in Sam's eyes and in the next moment she knew what she had to do. Acting on impulse, Abby leaned up and pressed her lips to Sam's.

Sam felt a wave of ecstasy shoot through him at the contact and before Abby had the chance to pull away, he had wrapped his arms tightly around her, pressing her against his body.

They both knew that it was too late to back out.

Abby sighed in satisfaction and twined her arms around his neck, not hesitating for a second. The kiss was intense and overwhelming, Abby had the feeling to have lost control the minute their lips connected.

She knew she was addicted and there probably was no cure.

But she didn't care. She wished they could stay like that forever.

Sam had a hard time keeping his hands around her waist but somehow he managed to. He wanted to run his hands down her body, to finally feel his mate's curves and hot flesh but he didn't want to scare her.

Abby's tongue moved so wonderfully against his and her mouth was sweeter than everything he had ever tasted and Sam felt himself quickly getting drunk. The noises that she made caused his head to spin and Sam thought for a millisecond about simply pressing her onto his desk and take what he wanted from her before he came to his senses.

Abby needed to breathe but she wasn't willing to let go of Sam just yet, so she continued to kiss him passionately until Sam broke the kiss.

They looked at each other, stunned and confused, not sure what had just happened. Sam looked at Abby's beautiful face, her lips were swollen from their rough kiss and her breathing was ragged.

Her eyes were dark with desire, begging him silently to kiss her again.

Sam had never felt so weak yet strong at the same time than in that moment. And then a new feeling, a feeling that was rather unfamiliar to his kind, took a hold of him. Fear spread through his veins like venom.

Abby was the first to regain control over her body, she let out a nervous laugh.

"So...that wasn't planned." She joked weakly and ran a hand through her hair. She had no idea what was going on with Sam but he seemed so reserved all of a sudden.

Was he regretting the kiss? She hoped not, because she sure as hell wanted to kiss him again.

Sam didn't say anything and just continued to stare blankly at her. Abby was crushed.

Shame and pain washed over her and she decided to bail, otherwise she would break down in front of him.

"I...I should go." She stuttered and waited for Sam's protest. She hoped he would ask her to stay but instead he simply nodded and looked away.

Abby swallowed hard, trying to cope with the rejection. She quickly turned around and hurried out the door, feeling her heart shattering like glass.

Sam watched her leave but he couldn't do anything. He was paralyzed. His emotions had taken control of him and he couldn't fight it.

He knew he should have called Abby back, he should have begged her to stay. Instead he just kept slient and let her go.

Later that night Sam was alone at home, pacing the floor of his living room. He had no idea how to make it up to Abby.

She probably thought he was a total jerk after he had pushed her to go on a date with him and then kissed her in his office only to reject her again.

Sam ran his hands through his hair and let out a frustrated sigh. The kiss had scared and confused him.

And now he was sure that Abby wouldn't want to see him ever again.

He could never have her and he would be destined to stay alone for all eternity...

When he was almost at his wits' end, a thought hit him. He needed help and luckily there was someone who could and would help him.

Sam pulled his phone out of his pocket and dialed Carmen's number.

"Am I...interrupting something?" He asked cautiously when she answered, fearing he might have called her at an awkward time. But then again, with Dean and Carmen it was always a bad time to be calling.

Carmen laughed, catching on. "No, you're safe. I'm in my car, heading home." She answered and Sam looked at his watch, seeing that it was shortly after five.

"Listen...I'm sorry to bother you..." He started nervously. Suddenly he felt all insecure, not sure how to talk to her about his problem.

"Don't be silly. What's the matter, sweetie?" Carmen encouraged. "Sam?" She asked when he didn't respond.

Sam closed his eyes. He was very vulnerable in that moment, it wasn't easy for a man to admit his fears and weaknesses to a woman. Even though he knew that he could trust that woman. Carmen would never judge him or see him with different eyes.

"It's Abby. I've figured out that much." Sam heard Carmen's voice through the speaker. "But you gotta tell me..."

"She kissed me." Sam interrupted her and heard how she gasped for breath. There was silence for a few seconds before she reacted.

"Aww, Sammy! That's so awesome. See, everything's going great. She'll be yours soon."

"I don't think so." Sam stated. He could almost see Carmen frown in confusion behind the wheel of her car. "Why? What did you do?"

Sam told her about everything and how he had reacted. "I got so scared, you know. And God knows what she thinks of me now."

"Everything's fine, Sammy. Just talk to her, she'll understand. I'm sure she was just as scared as you were but she's human and she doesn't know what this is really all about. She doesn't know that this isn't just another relationship that's about to start."

Hearing Carmen say those words was very calming. But he didn't want to get his hopes up. "You sure?"

"Yes." Carmen chuckled. "Sammy, I know you're very confused at the moment but it will change soon. Of course you're scared of making mistakes, but let's face it, sometimes you'll act irrational. You can't act as scheduled."

Carmen had a point. Sam had to admit to himself, that he had pictured how to win Abby over. There was already a whole scenario in his head.

So he panicked when something didn't go according to his plan. But Carmen was right, he couldn't foresee his own reactions and he had to accept that.

"It's not too late. She's attracted to you, Sam. We both know that." Carmen said quietly, as if reading his mind and Sam smiled.

"You're right. I know you're right." Sam said.

"Of course I am." Carmen said and Sam laughed. "Thank you, talking to you really helped." He added.

"Anything for you, Sammy. Call me if you need me."

"I will. Bye." Sam said and hung up the phone. He took a deep breath, calming his nerves.

Carmen was right, he had to talk to Abby. First thing in the morning.

The door bell sounded through the house in the next moment. Sam frowned, wondering who that could be and walked into the hall to answer.

His dead heart clenched painfully in his chest at the sight of Abby standing on the porch. Sam was speechless.

Luckily, he didn't have to say anything since Abby walked confidently passed him and into the house.

Sam closed the front door silently and turned around to face her.

"We need to talk." She simply stated and looked him straight in the eye. Sam was taken off guard and needed a few seconds to process her words.

"Right." He finally answered. "After you." He said and gestured towards the living room.

Walking into the room, Abby felt her confidence and strength leaving her and therefore her next words weren't the ones she had wanted to say.

"I know who the thief is."

Sam looked dumbfounded at her. What the hell was she talking about? "Excuse me?" He asked confused.

"I know who's stealing all the things from the hotel rooms. You wanted me to take care of that and I did. I'd wanted to tell you earlier but..." Abby swallowed and looked around the room, not daring to look at him.

Actually, she had come to him to talk about the kiss. She had been confused and hurt and wanted to clear the air once and for all.

It had taken her all her strength to gather up courage and go see her boss. It was a pretty bold move but she couldn't help it.

But now, she didn't feel courageous anymore. And had used the hotel thief as an excuse.

Sam looked intently at her, trying to read between the lines. He had been surprised at first that she had showed up at his door but now he was exhilarated.

Carmen had been right, it wasn't too late.

Sam stepped closer to her, determined to talk everything out. "Is that the only reason why you came to see me?"

Abby looked at him, locking their eyes again. But she couldn't say anything.

"I'm sorry." Sam whispered and cupped her face with his hands. Abby's breath hitched.

"I'd wanted to kiss you again but...you've confused me. I've never felt anything like this before. I've never been so attracted to someone in my entire life."

"I know what you mean, Sam." Abby whispered back and stepped away from him, not trusting herself in his presence anymore.

"You think I walked into your office with the intention to seduce you?" She said, getting annoyed. "I'm not that kinda girl."

"I know you're not." Sam said and took both her hands in his. "But if I had made you stay I would've lost control and let things go too far..." He trailed off, not wanting to end the sentence and scare her. He had made his point and Abby knew what he had left unsaid.

"I wanted to let things go too far...even though it wasn't my intention." She admitted quietly with a weak voice, shocking Sam.

He hadn't expected the confession and now he was even more confused.

Abby needed time to gather her thoughts and decided to change the subject. "You've got a nice house." She stated looking around the room again.

"Thanks." Sam replied, knowing she was playing for time.

"Too big for a single man, though." She added and raised an eyebrow. Sam didn't understand. "What are you hinting at?"

"You never been married?" She asked. "No kids from a previous marriage that visit you every weekend?"

"No." Sam answered, waiting for her reaction. Abby bit her lip, thinking about it.

"Very suspicious." She finally stated, making Sam laugh.

"Come on, there's gotta be a scandalous story at least."

"No, I'm sorry. I just need space hence the big house. I'm really boring and a total geek." He added.

Sam was standing in front of her with a little smile on his face, waiting patiently for her reaction. He looked so good in his black trousers and the white shirt that he had already worn earlier that day at work.

But now he had turned up the sleeves and taken off the tie. He was so handsome and sophisticated yet casual and sexy at the same time.

She didn't believe for a second that he was boring.

Abby smiled a little. "I like that. Plus, I'm relieved to hear that there isn't an ex wife out there."

Sam watched Abby walk through his living room, looking intently at a few pieces here and there. It was like she was meant to be there, she fitted perfectly into that room.

Suddenly Abby stopped and sighed. Her eyes roamed over his body. The way he was towering over her made her shiver.

She could feel an invisible power floating in the air that seemed to be pulling her to him against her will. She couldn't explain what it was though.

"What is it about you? You're always on my mind." After those words were out, Abby's eyes widened in fear. "Oh my God, did I say that out loud?"

"Yeah." Sam smiled at her. "Don't worry. I'm constantly thinking about you, too. I really want this to work between us."

Abby tried to breathe normally. "I feared that you'd changed your mind after...you know."

"No. Quite the contrary. Actually, I want to kiss you again now...with your permission." Sam said with a smile and Abby relaxed.

He walked over to her and leaned down to join their lips for a soft kiss. Like earlier in his office, it was overwhelming and they both quickly lost control over the situation.

This time, Sam let his hands run down her body, finally feeling her form. Abby moaned when Sam's hands came to a rest on her ass, squeezing it lightly.

Sam guided her backwards to the sitting area in the room. They both knew that their lives had already changed irrevocably.

A/N: Hey guys! So, here's the next chapter. As you can see, it's getting serious between Sam and Abby.
