Dean watched the woman take a step towards him, her green eyes blazing with anger at his remark. He knew he had already upset her and it amused him. He wasn't happy to see her, but he had to admit that she was nice to look at.

"You're right. It's been three hundred years." She said, noting how his eyes scanned her body hungrily and her anger disappeared instantly. She laughed at his reaction to her appearance, very pleased with herself. Her effect on Dean Winchester hasn't lost its power.

"Really?" Dean replied. "Well, time does fly, doesn't it?" His eyes were glued to her, taking in her tall and slim form in the short and strapless purple dress that clung tightly to her body, accentuating her long slender legs. Her red hair was straight and reached to her waist and she was wearing four inch heels which made her look even taller than she already was. She embodied every man's fantasy and Dean couldn't help but lick his lips.

Maybe he should consider taking a break and let her distract him for a while.

"I can't believe you kept your promise, Olivia." Dean said, finally looking her in the eyes.

Olivia crossed her arms in front of her full breasts and smiled sweetly at him. "I told you I would come look for you."

Dean started to grin, getting excited. "Right. I do remember now."

"Don't act like you've never thought about me in the past." Olivia snapped. She was growing irritated since Dean remained sitting carelessly in his chair, not even thinking about taking a step towards her.

"I've to admit, you've crossed my mind once or twice." He said nonchalantly, smiling innocently at her. "So, what are you doing here?"

Olivia wanted to slap him for being so snotty. She had been imagining how Dean Winchester would take her back into his arms after being apart from him for three hundred years. She knew he missed her, she had seen the lust in his eyes. So she had no clue why he was acting now as if she was a pain in the neck.

"Are you fucking with me?" She exclaimed and Dean's grin faltered at her words. He didn't have the nerve to pick a fight with her, so he decided not to provoke her anymore. But she really started to annoy him.

"Of course not, sweetheart." He said calmly. "I just would like to know why you've decided to come back into my life. What do you want from me?" He knew damn well what she had come for but he kept playing ignorant.

"Unbelievable you're still a stubborn dick! You know exactly what I want from you!" She barked and lept forward.

Dean feared for a second she was going to attack him but to his surprise she stopped dead in her tracks.

"Something's different about you." She stated quietly, no sign of fury in her voice anymore.

"I guess, I'm getting old." Dean joked and Olivia shot him a dirty look. And then she realized it. "You smell different." She stated in utter shock and Dean raised an eyebrow, totally unmoved.

"You don't like my scent anymore? I'm very sorry." He replied, looking her up and down. "Well, I sure am liking everything about you. But I'm talking about your looks here. You're personality has always been annoying."

"Dean, what the hell is going on? What aren't you telling me?" She demanded, ignoring his comment.

She took a seat on top of his desk and looked him over. He had taken off his jacket, turned up the sleeves of the white shirt he was wearing and loosened the tie. He looked so damn good in a suit; it brought out his handsome features and muscular body.

His appearance was still impressive; Olivia couldn't suppress a sigh as she kept looking at him. She could feel her body react and her knees turned to jelly. How was it possible that after three centuries he still had that power over her?

"Nothing's going on. Listen, I have a lot of work to do..."

"Dean, I missed you." She suddenly confessed. "I've been looking everywhere for you, you're all I can think about."

"Here we go again." Dean sighed. "Sweetheart, my answer's still the same, stop wasting your time."

"But I want you, Dean! You're my mate."

In that moment Carmen walked through the door, her warm and friendly aura filled the room, getting Dean's attention.

As soon as he caught sight of her he started grinning like a boy in a candy store. He hadn't seen her in what seemed like forever, ever since he had buried himself in work.

He missed her like crazy; it almost hurt physically being away from her even for just one day. He immediately felt a sharp tug in his heart, he could have sworn that the love he had for her had materialized itself and took a hold of his body. He was addicted to that woman.

The first thing that Carmen noticed was the tall dazzling and beautiful woman sitting on Dean's desk in a piece of material that you couldn't possibly refer to as a 'dress'.

Jealousy and anger stirred inside her but then she remembered Abby and remained calm. Just because a gorgeous woman was visiting Dean didn't have to mean that something was going on behind her back. After all, she hadn't caught them in a compromising position. But she had heared what the woman had said to Dean.

You're my mate. She was definitely a potential threat and Carmen decided to be careful. But when she looked over at Dean and saw him smiling stupidly, she relaxed completely.

He looked so adorable and innocent. He was obviously thrilled to see her and it warmed her heart. She smiled back at him lovingly, forgetting about the other woman.

"Who the hell are you? Dean, who's that woman?" The red-haired girl suddenly exclaimed, interrupting the perfect moment between Dean and Carmen.

At Olivia's words Carmen lost her self-composure which she had kept up successfully until that moment. Her eyes turned dark, sparkling cold and menacing. She slowly walked over to the girl who was invading her territory.

Dean saw the joyful spark in Carmen's eyes turn into fury within seconds and he remembered that Olivia was still in the room. He sensed Carmen's anger and as always it turned him on. His mouth was dry and he wanted to grab her and take her right there on his desk. The lack of sex lately caused all the blood to leave his brain.

"The more appropriate question is, who the hell are you, sweetheart and what are you doing in my house?" Carmen said, her voice dripping with despisement and fury.

Olivia hopped off the desk and stepped closer, glaring at Carmen.

Dean watched them, a little scared of what might happen next. He couldn't help but notice how different they were. Olivia was hot as hell, her whole appearance was advertising one thing - hot and sweat-dripping sex. Everything about her was devilish, her hair color, her sense of style and her scent.

But Carmen, his beautiful Carmen was able to take every man's breath away. Her hazel eyes seemed to be changing from brown to green all the time and never ceased to mesmerize him. She was wearing a simple business dress, but it was pink and satiny and made her skin glow mysteriously. His journalist was elegance personified; she was sexy - very sexy - but in a subtle way.

He chuckled lightly at the absolutely conflictive women standing in front of him. Bad mistake.

Carmen spun around, shooting him a dirty look. "What are you laughing at, Winchester?"

"Nothing, baby. I'm sorry." He replied nervously and swallowed hard.

"You'll be very sorry, honey. Believe me." She threatened and turned back to Olivia. "Now you, sweetheart. Answer my question."

Ignoring her words, Olivia looked the brunette over, disapprove evident in her eyes.

"So, you're the girl he's fucking at the moment." She stated matter-of-factly and Carmen narrowed her eyes.

Dean jumped up and walked over to Carmen, pulled her away from Olivia and stepped in between.

"She's my mate." Dean explained, locking his eyes with Olivia's. The redhead wanted to kill him, he could feel it.

"What? You've got a mate?"

"Yep. Why so surprised, it's been three hundred years." Dean shrugged his shoulders, smiling. "People change."

Carmen wasn't proud of it but she got scared. Olivia was seriously pissed by now and she could only guess how she would react to the news. In another space and time, she would have felt sympathy for the girl, but she had clearly stepped over the boundaries.

"As heartbreaking as this is, but I have no time for that." Carmen said disparagingly and looked at Dean. "I have to get back to work, we're having an important meeting."

"But you'll be back around six, right?" Dean asked.

"Yeah." Carmen replied and leaned up, pressing her lips to Dean's. She kissed him long and hard and possessively, marking her territory.

She glanced briefly at Olivia and walked over to the door.

Olivia was still speechless. She didn't know what to say, her worst nightmare had come true. She looked between Dean and Carmen in shock and horror.

Dean had betrayed her. She was going to make him pay for that.

"Honey?" Carmen suddenly turned around one last time, facing Dean.

"Yes, baby?" He replied, extremely amused and fascinated by her behaviour. He had thought she would fume and attack him but she had surprised him with her whole reaction. She was handling the situation with such nonchalance that he felt the need to put her on a pedestal and worship her.

Carmen noticed the look on his face and had to hold back a chuckle. He wasn't sorry or remorseful, rather the opposite; he was enjoying the attention. She should have figured.

But her expression was blank as she spoke up, not showing her real emotions. "I want that person out of my house by the time I get back home."

Dean nodded, still smirking. "Understood."

She glanced over at Olivia again, fighting the urge to slap her. When she was sure that she had regained control over her feelings, she turned around and walked out the door.

"Carmen, wait!" Dean called after her and left the study. He was pleasantly surprised when he spotted her waiting in the hallway for him; she hadn't taken off like he had thought.

He stopped in front of her with a bright smile and Carmen looked questioningly at him. Dean didn't say anything and leaned down, pressing his lips to her mouth. It was a soft and gentle kiss, his lips moving slowly against hers, leaving her breathless when he pulled away again.

"It's so good to see you, baby." He whispered huskily against her lips. "We've been apart for twenty-four hours and it almost killed me."

"But you've got yourself some company, so it couldn't have been that bad." Carmen kinked an eyebrow provokingly, a dangerous glow in her eyes.

"You're mine, Mr Winchester." She stated menacingly.

"Possessive much?" Dean simply replied and chuckled lightly, pulling her roughly to his body.

"Very." Carmen felt his erection press against her stomach and noticed the obvious lust in his eyes.

"Two women fighting over you turned you on, huh? You liked it, didn't you?"

"Maybe. I've to admit that it had the desired effect." He smirked, sensing her annoyance. "But it's you who drives me crazy. The minute you walked into the room I've had this massive hard on." He ground his hips into her, emphasizing his words and Carmen gasped.

"Plus, I'm sex-deprived, baby. We haven't done anything in two days. Not even some handwork!" He sounded so desperate and Carmen laughed.

"Aw, poor baby."

"Promise me, you'll take care of me tonight." He said in a deep, low voice, knowing Carmen wouldn't turn him down.

"Of course I will. But now, I really have to go." Carmen glanced over his shoulder to the door of his study.

"Hey, why don't you ask your girlfriend to help you out since she's waiting for you anyway." She added sarcastically, but she wasn't able to hold back the aggressive undertone in her voice.

Dean couldn't help but smile. "Come're." He whispered and pulled her close, kissing her deeply again. Carmen couldn't suppress her feelings; her arms wound automatically around his neck and she moaned softly into his mouth.

He broke the kiss and moved further down to nibble at her jaw before he licked the column of her throat, sucking hotly on the soft flesh. He heard Carmen take in a desperate breath.

"Dean..." She moaned into his ear and he could smell how aroused she already was. He buried his face in her neck, breathing in her scent. The way it mixed with the perfume she was wearing was intoxicating. Carmen smelled like meadow flowers; fresh, natural and sweet.

"I love your scent, baby." He whispered huskily and Carmen shuddered. She got so distracted that she almost forgot about the tall redhead in the other room.

And as much as she hated to leave Dean with a hot woman alone, she had to. She had to trust him.

After all, she had told him she trusted him. Stupid. But now was the time to prove it.

"Dean...I really have to go now." She tried to get out of his embrace, but he wouldn't let go of her. "Please...I'll be back in a few hours and we'll do whatever you want."

Dean let out a disappointed groan, but decided not to protest. He could feel that Carmen's patience was wearing thin and he didn't want to enrage her.

"I'll be here, waiting for you." He said quietly and kissed her one last time.

"You really should go take care of that readhead now." Carmen said sweetly, turned around and left.

Dean ran a hand through his hair, knowing he had a lot of explaining to do later. His stomach turned at the thought. He would rather not tell Carmen anything about Olivia.

And if she hadn't showed up, he would have never even mentioned her. He would have kept silent about that part of his life for all eternity.

Because it would hurt Carmen.

He had already regretted getting involved with Olivia a long time ago. It had been a huge mistake and he had thought he would never see her again. But now she was back and he could only hope she wasn't going to cause much trouble.

Dean sighed and headed back into his study to get rid of one of the demons from his past.
