Sam believed Olivia at first and felt a panic attack approaching before rationality took control over his mind and he calmed down. She was trying to manipulate him again.

In what universe would his brother ever be happy to see her again anyway?

He had had a thing with her once, but it was a very long time ago, even for a vampire. And the circumstances were different back then. Now, Dean was with Carmen and happy. Sam knew that even his brother wouldn't put his realtionship on the line just to hook up with an ex. No matter how persuasive that ex was. He shook his head, letting out a relieved laugh. He was amused that he had bought Olivia's words and let her fool him for about a second.

Olivia noticed that her tricks weren't working on Sam and grew irritated when she heard him laughing, but managed to hold back her anger. "What's so funny, Sammy?" She asked softly, her voice as sweet as honey.

Sam ignored her, adjusting his tie and straightening out his shirt before putting his jacket back on."When are you going to give up, Olivia?" He mumbled under his breath, feeling how she tensed up behind his back."He doesn't love you."

When he met her gaze, her eyes glistened with hatred and hurt pride."How do you know? You've never loved someone, Sam Winchester. And you never will. Do you hear me? You'll never meet your mate!"

Sam sighed, realizing that he had gone too far. She sounded so bitter and broken that he almost felt bad for her. Only she had invaded his privacy and was keeping him from getting his rest. Sam was on the verge of a nervous breakdown and she was getting on his last nerve. So he turned around without another word and left the bedroom.

"Where are you going?" Olivia jumped up in shock, her eyes widening and hurried to catch up with him.

"Back to work. I'm very busy and really don't feel like dealing with you right now." He explained calmly, taking his briefcase and heading for the door.

"But Sammy..." She started and trailed off when she saw the look on his face. He had changed so much. Back then he had been willing to do anything for her. And now he was so cold and indignant towards her. She was totally confused.

"What's the matter? Are you surprised that I won't do as you please?" Sam asked, opening the front door and waiting for her to leave."Just for the record, even though I'd known you weren't my mate, I would've given you everything, Olivia. Everything. You shouldn't have screwed with me like that."

He walked out and she sprinted after him, processing his words."Sammy, wait!"

"Sorry, gotta go. Call my secretary for an appointment if you wanna talk to me." He said and then stopped, turning around."One more thing, do not call me Sammy."

Olivia watched how he got in his car and drove away. Rage flamed up inside her and she swore to take revenge on Sam Winchester. She hadn't managed to manipulate him again and he really had had the nerve to turn her down! He was messing with the wrong vampiress and he was going to pay for that.

Dean was waiting downstairs for Carmen to come out of the shower. After she had stormed out on him he had quickly followed her into the bathroom and sweet-talked her into another round. She had protested weakly at first and then given in eventually when he had stepped to her under the shower.

He ran a hand through his still wet hair, a smirk appearing on his face as he remembered Carmen's sighs of annoyance which had turned quickly into pleasured noises. Unfortunately, she kicked him out shortly after they had come down from their highs, telling him she needed some privacy to finish showering.

Dean didn't want her to go to work. He wished for her to stay, so they could spend the day together. Recently they had been getting along pretty well and for the first time in decades everything between them was running smoothly. Maybe the night before had been kind of a relapse and they had fallen into their old pattern for a while, but only because of Olivia.

Now that she was gone, they could continue like nothing ever happened. Even though the fact that they had to talk about the incident still remained. After all, Carmen deserved to know the truth and they needed to communicate if they wanted their relationship to work. Dean rolled his eyes as his brother's words crossed his mind. He was constantly telling him that, communication was Sam's solution for everything. If it only were that easy.

But Dean decided to finally listen to his brother's advice. He wanted to know where she had disappeared to after work. This time he was honestly willing to stay calm and hear her out. The unbearable thought of Carmen with another man was plaguing him; he needed to know for sure whether she had cheated on him or not since he wasn't able to tell.

He had always thought he would notice if she was unfaithful, but right now he was helpless and not seeing any signs on her. There wasn't even another scent on her; her blood had tasted pure, so he knew no one but him had fed on her.

But what if she was hiding it from him?

He knew it was impossible to cover up any kinds of marks, but what if Carmen had found a way of making them disappear? On top of that all, she had shut her emotions off, making it harder for him to read her. And then they had attacked each other; lust had blurred their minds and had wiped out any other feeling.

Dean shook his head at the train of thoughts; it was ridiculous and he had to stop torturing himself. Carmen loved him and would never hurt him; he had to hold onto that. She hadn't even interrogated him about Olivia - and then it hit him. She probably didn't believe him, either. Why else hadn't she confronted him about her earlier?

He was getting sick to his stomach, realizing they indeed needed to talk before it was too late. Dean banned those thoughts from his mind though and focused on checking his messages instead. After all, he had a long day full of work ahead of him.

Carmen descended the stairs, entering the living room. Dean caught immediately her attention since he was only wearing pants, his bare back glistening deliciously from the shower and Carmen stopped in her tracks, a sigh escaping her. She was still dazed after their hot shower and almost bursting with happiness.

What was that man doing to her? A dreamy smile appeared on her face and she had to hold back a giggle. Now she had no idea how Dean had managed to seduce her again since she had tried everything in her power not to give in. But eventually she crumbled, because he had used every trick on her and she got weak.

But how could she ever resist him anyway?

She knew she would be sore and feeling the aftermath of their excessive love making by the next day, but didn't care at this point. Besides, she loved it. Loved it to be reminded of how it felt having him inside her.

Carmen walked over to him and ran her hands softly along his strong muscular back, before wrapping her arms around him from behind and placing a kiss onto his shoulder blade.

"Oh now look who's feeling bad for kicking me out." Dean smirked, his tone playful."Forget it, sweetheart. Not gonna forgive you."

"You sure?" She whispered in her unresistibly raspy voice, her breath tickling his ear and neck. She started to leave hot soft kisses on his shoulders, kissing up his neck and licking the sensitive spot behind his ear before she bit his earlobe. She smiled when Dean forgot to breathe and continued with her assault, letting one hand wander down his stomach and slip into his pants to feel his hot awaiting flesh.

"Is there really nothing I can do to make it up to you?" She purred again, enjoying his reaction. She took his semi-hard length into her hand, sweeping her thumb over the tip teasingly.

"You'll have to do better than that." Dean managed to say, arching into her hand and suppressing a groan. Carmen chuckled, her lips parted and her tongue licked the side of his neck before scraping the soft spot with her teeth.

She pulled her hand out of his jeans and Dean frowned at the loss of her touch, disappointed that she had stopped.

"Do you want me, Dean?" He suddenly heard her ask, her voice trembling with vulnerability and fear. He swllowed hard, wondering what had caused her sudden mood change and turned to face her, gently taking her hands in his. He looked her over, seeing her sad face, her eyes glistening with tears. She had put on her red silk morning robe but closed it only loosely, leaving a generous spot of naked skin in the front.

The combination of her insecurity and cleavage had the effect of a punch in the guts. It took his breath away and he was fully erect again. Dean Winchester was a real perv.

"Baby...how can you doubt it after last night?" He asked softly.

"I just...I need to hear it again." She said quietly, looking up at him so innocently. Dean smiled lovingly and cupped her face, kissing her lips.

"I want you so much, baby." His hand travelled down the front of her robe, slipping under the material to caress her breast."My beautiful Carmen...you've no idea what you do to me." He said huskily. "Admit it, you're wearing that to torture me, right?"

"Maybe." Carmen replied, a bright smile slowly stretching her face."Is it working? I can see you kinda have a problem there." She added, noticing the bulge in his pants.

"Only because of you." He pulled her close, joining their lips for a kiss again. A mischivieous glint appeared in Carmen's eyes in the next second."I'm sorry for kicking you out of the shower and I'll make it all up to you, sweetie." She said with a sweet smile, taking a step back.

"But not now." She vanished before his eyes and Dean blinked in confusion when a strong breeze suddenly hit his face. He heard her chuckle upstairs."Two hundred and ten years, sweetie. And you still fall for my acts!"

Dean let out a frustrated groan."You're such a bitch, Carmen!" He yelled, realizing she had played him once again. Mumbling incoherent words he went to his study, sulking.

Carmen quickly got dressed and since she felt a little bad for teasing him like that she went to apologize to him. She knocked on the door before entering his study. Dean was sitting behind his desk, properly dressed for work.

"Dean..." She started cautiously. "Dean, I didn't mean it."

He ignored her and refused to listen to her as she tried to apologize, pretending to go through some files. He was pouting and not willing to forgive her for leaving him so horny again.

"This isn't funny at all." He finally said, shooting her a cold look."You always do that and I can't take it anymore. Stop leaving me all hot and bothered, it's too stressful and I'm going crazy!"

"I'm sorry, baby." Carmen repeated once again, but wasn't able to suppress her smile. She found it very amusing how frustrated he was.

"I won't do it again, I promise. Do I get a goodbye kiss at least?" She took a step towards him, but Dean held one hand up, stopping her from coming closer.

"You stay away from me, you...you witch. Now I'm pretty sure you are one. An evil sadistic witch that's what you are. And your apology isn't sincere at all, I can just tell." He rambled, trying not to look her way.

"I assure you I'm not a witch." Carmen chuckled."Just an average vampiress." She added modestly, but her smile was evil.

Dean sighed in exhaustion and then looked at her, his eyes turning dark."You'll start paying as soon as you get back, sugar."

His voice was low and threatening and Carmen felt a hot wave of fire wash over her at his words.

"Can't wait." Carmen's eyes sparkled and she licked her bottom lip before heading for the door. She was in a good mood when she left the house, but when she arrived at her work place a rather unpleasant surprise was awaiting her and her good mood quickly vanished.

Carmen got off the elevator on her floor, making her way towards her office, but stopped in her tracks when she saw a woman sitting on Jason's desk laughing and flirting with him. Even though her back was facing her she recognized her instantly. Her stomach turned and she took a few deep breaths to prevent herself from having a nervous breakdown.

"What's going on here?" She demanded and they both turned around at hearing her voice. Olivia was smiling slyly, obviously very pleased with herself.

"Hi Carmen." Jason greeted her happily."You don't know, do you?"

"Know what?" She was growing irritated with each passing second.

"Olivia took the free spot and is going to work on our floor from now on." Jason explained, a little confused about Carmen's behaviour. He wasn't sure why she was so upset.

Carmen looked at Olivia who was still smiling, a hint of despite evident in her eyes.

"Jason, could you get me some coffee, please?" Carmen said, not averting her gaze from Olivia. When he was out of sight she spoke up again."What are you doing here?"

"You're not that naive, Carmen. You know the answer to that question." Olivia got off the desk, glaring at her. "He's mine. And I'm going to get him back."

Carmen stood there, unable to muster up a reply as Olivia walked away. Her words were still playing in her head, minutes after she had left. Carmen was shaking with fear, realizing that Olivia was a serious threat. Apparently she was staying for good and wouldn't give up until she had won Dean over. And he was going to fall for her. Olivia was gorgeous.

She was going to lose Dean – the revelation hit her hard and she stopped breathing for a minute.

"Hey, you okay?" Carmen looked up and saw Jason standing next to her, looking concerned."You look really pale."

"I'm okay." She said, forcing herself to smile."Can you get my mail, please?"

"Actually..." Jason started nervously and Carmen was on alert. What else had happened during her abscence?

"What?" She asked.

"I'm assisting Olivia now. I'm sorry." Jason answered, blushing terribly. Carmen felt like punching him."Why? What did she promise you?"

"Nothing, it wasn't my idea. She talked to the boss and somehow convinced him to assign me to her."

"I see." Carmen choked out, feeling absolutely deceived and betrayed. She felt like turning around and running away. Never come back again. But she couldn't do that. She had to stay and pretend as if everything was alright. How was she going to survive that day?
