Author's Note: So here is a one shot I came up with while I'm having writer's block on my other story. Hope you like it. it is an Alec/OFC. I'm personally not an M/A fan, I prefer M/L. I'm not sure if I'll just leave it as a one shot or maybe turn it into a story. It all depends on how it's received. Please read and review. It helps me greatly. Enjoy.

Disclaimer: I, of course, own nothing but Rowan. Too bad because I really like Alec. ;)

The pounding on his door continued. He had hoped that if he ignored it whoever it was would go away. As usual, he had no such luck. He grabbed his watch off his makeshift nightstand. His enhanced vision easily read the numbers in the nonexistent light. He groaned as he saw that it was only three in the morning. He had gotten home around two after a raiding job and had immediately made his way to his bed and collapsed into a deep sleep.

Wiping the sleep from his eyes he swung his legs over the side of the bed and stretched. Standing up he yawned and scratched his side as he searched for a pair of sweats to throw on. While he was not bashful, he was sure whoever was on the other side of the door would not appreciate the early morning show. Although, it would serve them right for waking him. Yet, it would probably get back to Max and he'd have to deal with the X-5's furious temper. Not like he hadn't been on the receiving end of it before, but he just wasn't up to handling Max right now.

Lately things had been very tense for her. She was designated leader of Terminal City, was busy trying to work out deals with the government for the safety of all transgenics, and trying to figure out how to deal with the fact that she was mankind's only hope of survival. To top it off all of their leads for Manticore geneticist had been dead ends. Leaving Max still unable to pursue her relationship with Logan. This lead to a sexually frustrated Max and a sexually frustrated X-5 female was not pleasant. He contemplated his decision as he found what he was looking for. Another round of banging ensued.

"Yeah, yeah I'm coming. Hold your horses." He was jumping into his sweats as he made his way to the door. He pulled them on fully, letting them hang low in his hips, and peaked out the peephole into the hall.

"Ro?" He looked at the visitor on the other side, slightly surprised to see her standing there. He remembered the first day he met Rowan Calden or Ro as she liked to be called. Her family had fled to T.C. after being discovered. She was what most would consider an anomaly. She wasn't like the anomalies that were housed in the basement at Manticore, but she was almost one of a kind.

Ro was a half-breed. Her mother was an X-2, known as Cadence. Her DNA had been spliced with a lot of jaguar. Her eyes and the way she had moved reflected that little known trait. Her father was an ordinary. Her parents had met while her mother was on a job as a medic for the Army. They had fallen in love and ran away before she was sent back to Manticore. They had been in hiding for years, taking on new identities. They then received a surprise one day, in the form of Ro.

Ro had the golden hair of her mother and the deep ocean blue eyes of her father. Alec hadn't really met them. They had been attacked just as they were outside the city's gates. Alec remembered that day that took place almost a year ago. The mob was vicious. Reinforcements were sent out to save them. Unfortunately, Michael Calden had been fatally wounded. They were able to get him into their poor excuse of a medic ward before he had passed.

Cadence was critically wounded. She held on for a week before she passed. In all that time, Alec had rarely seen Ro move from her mother's side. It was hard for him to understand. Never having parental figures himself, he couldn't understand the bond formed between a parent and child and he didn't want to. He only went to the ward when it was required, therefore he never talked to Cadence, but Max had. Max was curious about Ro. He had later learned that Max's sister Tinga had also had a child with an ordinary. She was trying to figure out if she would have to bring her nephew to T.C for safety. Everything Alec learned about Ro those first few weeks was through word of mouth from Max. When her mother died, Max made sure that Ro was looked after. She was afraid she would run. Ro's mother had said that Ro hadn't developed any traits of a transgenic. She was an ordinary in all aspects, but they soon learned that really wasn't true.

Max had decided Ro was to be trained. She didn't want her on her own and unable to defend her self. Since none of the other transgenics seemed to care for Ro, Max had designated Alec as her instructor. He didn't really have anything against the girl, but he felt he could've spent his time doing something more useful. However, Max gave him a look and one hell of a right hook and he was on the job.

He found that she knew some basic defensive moves that her parents had taught her throughout her twenty-three years, but there was still a lot of work to be done. She wasn't exactly in great shape. She wasn't fat, but she wasn't skinny either. She carried a little extra weight, but as they trained it disappeared and while she would never have the body of an X-series, she definitely had all the right curves. Alec wasn't blind. He knew how to appreciate the female form and Ro had developed a form he could definitely appreciate. He also saw other X-series males noticing the change as well and it made his blood boil. They had wanted nothing to do with her at first and now they were trying to get on her good side. Thankfully, Ro didn't fall for any of their bullshit. Alec was rather proud.

As they continued their training, Alec noticed subtle changes in Ro. When she threw an X-4 named Joe halfway across the room, Alec took her to the medic ward once again. X-5 626, also known as Doc, took a sample of her blood and ran some test on what little equipment they had at the time. He then sent for Max, stating that she needed to be informed of this as well. Turned out Ro wasn't quite without transgenic traits as her parents thought. They had just been dormant. When she had come to T.C., they were activated to fight all the biohazards that covered the area.

This caused Alec to become more watchful over his friend. He didn't know when exactly he had started considering her a friend, but he knew it was understood on both their parts. The only people she only seemed to talk to were him, Max, Logan, and Joshua. Most of the time it was him though. He felt protective of her and he couldn't explain the strange sensation he felt when she wasn't beside him and he had no idea where she was.

"Alec?" His body tensed at the panicked sound of her voice. "Please let me in." He saw the frightened look on her face and watched as she nervously looked both ways down the hall. Something had her spooked and he yanked the door open. As soon as he did, he froze.

This is not good!! His mind was warring with his rigid body. He looked at her then heard a growl come from her right. Whipping his head in that direction, he saw an X-4. He stepped out, blocking her form the other male's view. His arm came back and pushed her inside of the apartment. The other male's growl became harsher and he crouched. Alec's lips pulled back barring his teeth and a deep warning growl rumbled from his throat. Crouching down in a defensive position, he assessed the situation. He would easily have this guy on his ass in less than five minutes. The X-4 realized this and barred his neck in submission and slowly began backing away. Alec remained in that position, even after the X-4 had vacated the building.

"Alec?" Her shaky voice pulled him out of his aggressive stance. He stood and took a deep breath. That's when her scent hit him again and he groaned. He turned and walked back into the apartment. He really didn't want her in here right now, but he knew if he sent her to the ward on her own she would be attacked once again. He had to call Max and lock himself up in his room until she left. He knew that even if she left he still wouldn't sleep. Her scent would still linger in his apartment. Maybe Max could knock me out.

"Alec? What is going on?" He turned to her and he knew right away that it was a mistake. It was summer and the temperatures were high, even at night. She was dressed accordingly in an attempt to sleep. Her tank top clung to her heaving chest. Her shorts cutting off mid-thigh. Her pale skin was covered in a fine sheen of sweat. She had obviously run here, searching for his help. He was struggling to reign himself in.

"What…" He cleared his throat, hoping she hadn't heard the strain in his voice. "What happened?"

"I…I don't know. I woke up feeling strange. I figured I should let Doc check me out since I seem to keep changing. On my way there I ran into that guy. He attacked me. I managed to get away from him, but he tracked me down. So I ran here for help." Alec swallowed the lump that had formed in his throat at the sound of her voice. He never realized how angelic it sounded.

"You need to get to the ward now. I'll call Max." He turned and walked towards the kitchen.

"Why can't you just go with me?" He closed his eyes and clenched his jaw. Her scent was overwhelming him and it wouldn't be long before his instinct won out. He leaned forward onto his counter. His hands gripping it tightly and turning his knuckles white.

She couldn't figure out what was going on. She woke up with this urge. One that she had never had so strongly. She figured someone down at the ward would be able to help her and explain what was going on. When she ran into that guy a part of her reacted strongly to his male presence, but another part of her was shouting not worthy. She didn't know really why she ran to Alec. She just figured he could get this guy away from her and help her get to the ward safely.

When he opened that door, she was stunned into silence. She had seen his body before in their training sessions and had always admired it. She'd even admit she had a crush on him. Who wouldn't? Yet, she knew he only saw her as friend. Besides why would he want a half-breed when there were plenty of single X-5 females running around? Looking at him now though, she saw things differently. His muscles rippled beneath his taut skin. His movements were fluid and graceful, but carried with them the threat of his lethalness. He was a strong man. A man capable of protecting her. She had to admit when she saw him react to the other guy, she was turned on. The way he removed the threat without even fighting had her entranced. The voice in her head was now screaming worthy. She closed the distance between them.

"Alec?" The sound of her soft voice almost undid his resistance. It wasn't until she placed her hand on his arm that his resolve broke. The feel of her soft skin against his hard, scarred flesh sent his senses into overdrive. He moved before she could react. Grabbing her wrist, he quickly turned and pulled her flush against him. His other arm snaked around her waist holding her securely to him. She was not getting away from him now.

She looked into his eyes and gasped. His pupils had dilated, almost making them deep black pools. She felt herself moisten and fell slightly into him. Her knees no longer able to hold her up. She didn't quite understand what was happening. All she knew was that Alec was the only one that could stop this ache inside her.

His arms tightened around her as her body molded into his. She fit perfectly. He lowered his head to her neck, breathing her in. He was pleased to find that only her scent was on her skin. The other male had not managed to scent her. He growled in approval and he felt her shudder. He took another deep breath, inhaling her scent and found that something else permeated the room. Sniffing, quickly noted that it was her arousal. He growled once more and pulled her tighter against him. He licked her neck savoring the salty taste of her skin as he began rubbing against her. He was determined that she would carry his scent. He heard soft mewling sounds coming from her throat and it turned him on even more.

He slowly raised his head and looked at her face. Her eyes were closed and her lips slightly parted. Sensing his gaze upon her, she opened her eyes and his breath stuck in his throat. Her pupils were dilated almost completely obliterating the blue he had come to love, but he realized he loved this wild look too. He began walking her backwards towards the room. He was unsure how long her heat would last since it was her first one, but he sure as hell knew she wasn't leaving his side until it was over.

Once inside the room he kicked the door shut with his foot. His gaze quickly left her as he swept the room. It landed on his dresser. It wasn't much, but it would hold the door and keep out disturbances until he had his fill of her. He bent his head and lightly nipped at her lips. She whimpered and he felt a rush as he hardened even more. He guided her back to the bed and eased her down upon it, making sure to cover her entire body with his length.

"Stay," he growled out huskily. She nodded and he let her go. Positive that she would remain in her position, he stood and blurred the short distance to the dresser. He could've walked it, but he was in a hurry. He knew Max was going to expect him at Headquarters later in the morning, but he really didn't know if he would be able to pull himself away.

Once the dresser was in place, he turned to look at her. The sight before him erased any other thought from his mind. She lay upon his bed watching him, golden hair spilling out across the pillows, the moonlight casting a soft glow upon her pale skin, and her eyes glowing full of lust. He stalked over to her. Her eyes on his every movement. He was like a predator and she was the meal he was about to devour.

Suddenly he pounced onto the bed, startling the breath from her. He held himself above her, before gently dipping down and covering her with his body once again. Realizing she had way to many clothes on to properly scent her, he ripped her shirt over her head. His gaze quickly shifting to her bare breasts. They called to him and he dipped his head. Taking one his mouth he sucked and nibbled, bringing her nipple to a hardened point. Once he was satisfied he switched his attention to the other breast.

She withered underneath him. Arching her back to give him more and consequently rubbing her hot core against his hard erection. When she did that a deep, guttural growl escaped his lips, smothered by her breast. Removing his mouth, he let his head rest upon her chest. He listened to her heart's rapid beating and reveled in the fact that he was the one to cause it. He sat up on his knees and, teasingly slow, pulled off her shorts. He lowered himself between her legs and nuzzled against the fabric of her light blue panties. He never thought plain cotton panties could turn him on. God help him, he was a goner. He deeply inhaled the scent of her arousal and, if it were even possible, he grew harder.

"Alec." Up until that point she hadn't said a word, but as his name rolled off her tongue in that deep, lustful moan, he completely lost control. His eyes flashed in the moonlight and then he ripped her panties off. He quickly flipped her over onto her hands and knees. He pushed down his pants so they sat just below his ass. He positioned himself behind her and leaned over rubbing himself against her back. She would smell like him. That was a fact that there was no getting around and if she didn't he wouldn't let her leave until she did.

Quickly he thrust into her. Her cry of pain was lost beneath his roar of satisfaction and triumph. No other man had ever been inside her and no other man ever would. He was her first and he would be her last. He knew there was no turning back now. He thrust into her hard and determined. Her cries of pain soon disappeared into whimpers which turned into moans of pleasure, but it wasn't enough for him. He wanted her to scream. He knew most of T.C. had probably already heard them and knew what was going on, but he wanted the rest of Seattle to hear her as he took her. He wanted everyone to know that she now belonged to him. She was his woman, his love, his mate. As soon as that word flashed in his mind, he let out a primal roar and began thrusting harder and deeper into her. He slowed his thrusts as he leaned down, his head next to hers.

"Mine," he growled out as he slammed himself into her cervix. She cried out in a mix of pain and pleasure and he held himself there. Lightly pumping, but barely moving from that spot. That was where he wanted to be. That was where he would spill his seed. He was determined that she would be full with his child by the time they were done and if not? Well, neither of them would leave this room until it happened and God help anybody that tried to intervene. His head shifted so that his nose nuzzled her neck. He took in the smell of their mixed sweat on her skin. The scent of it making him growl and give one hard thrust into her again.

"Mine," he purred softly into her ear. She felt herself quiver around him at the tenderness of that word. Somewhere deep in her subconscious she knew he was claiming her as his mate and inside she roared with approval. She wanted this. They both did. She wanted him and he wanted her. It was a game they had been playing since the first time they laid eyes on each other, but the game had finally come to an end and both of them would come out the victors.

"Yours," she moaned out softly. With that one word he began to pump hard into her once again. He was so deep. She had never felt anything like this before. He was her first and only. She knew that. She knew no other man could touch her as deep as Alec always would. Her rational, ordinary side was scolding her for not using protection, but her animalistic side didn't give a damn. In fact, part of her hoped she would become pregnant, firmly cementing them as mates.

He growled once more in her ear. It was a loving, tender, but demanding growl. Instinctually she lowered her head and exposed the side of her neck to him. His teeth clamped down upon the juncture between her neck and shoulder. It was light at first, but as he picked up speed it became harder. Finally he broke her skin, leaving his mark upon her. Making it known to everyone that she now belonged to him and anybody that tried to touch her or hurt her would pay dearly.

His bite sent her over the edge. She screamed as her muscles clamped down on him. He released her and let out his own animalistic roar as her climax set off his own. He pumped into her hard and deep a few more times, and then held himself deep with in her. He would make sure his seed hit its mark. They collapsed onto the bed, him still on top. He soon realized he was probably crushing her. He rolled to his side, taking her with him and making sure her never left her. Soon they fell asleep with him still deeply seated within her.

The sun peaked through the blinds and hit Alec right in the eyes. He groaned and rolled away wrapping his arm around the body next to him and burying his face within her hair. She moaned and stretched a little. Alec realized that she was waking up and that he would have to as well. They had a lot to talk about. It was mostly going to be him explaining the consequences of last night. He only hoped that she didn't regret it. She turned her head to him and he looked back into the deep blue eyes that he knew so well.

"How do you feel?," he asked. His voice was rougher than he wanted it to be. He cleared his throat and waited for her answer.

"Sore," she said. She tried to move around to face him, when they both realized that he was still firmly inside of her. The realization made him swell once more and she gasped. He quickly extracted himself before he lost control again. They need to talk and get everything out on the table before they continued further.

"Sorry," he said, once she rolled over.

"It's okay. It's a…a good kind of sore." She smiled at him and it caused his face to light up in his own. He could tell by the look in her eyes that she didn't regret what had happened between them and he was thrilled. He honestly didn't know what he would've done if she had. His gaze drifted down to her shoulder. He felt himself harden even more as he saw his mark upon her skin. She was his and nobody was going to change that. He moved his hand up and smoothed away the dried blood. The mark would scar and be a permanent reminder to everyone. He felt pride well up in his chest. She glanced down at his hand and saw some dried blood on her chest. She gripped his hand lightly, stopping his progress.

"What does this mean?," she asked softly. A part of her knew what it meant, but she wanted his confirmation.

"It means…" He gently rubbed the mark once more before taking her hand in his and leaning his face close to her. "It means you're my mate. It means you are under my protection, that nobody will touch you or hurt you without paying the price." He gripped her hand tighter with each statement, making sure she heard the conviction in his words. She felt her heart swell and felt like it would burst inside of her chest. She had the man she wanted. A man that wanted to protect her and love her.

"So should we head to the medic ward still? I mean I still have that strange feeling?" He scented the air and could tell she was still in heat. It wasn't as strong, either because they mated or because her cycle this time would be shorter, getting a little bit longer the more she had them.

"You're in heat."

"Heat? You mean like a cat or a dog?" He nodded his head.

"Yes. That's why that X-4 went after you last night. When a female X-series is in heat it is very difficult for a male X-series to resist. A lot of fights have broken out because two males are fighting for a female in heat."

"So anytime a female goes into heat, you're going to have the urge to do what we did last night?" He could hear the hurt in her voice. He quickly shook his head and brought his hand to cup her face.

"No. You're my mate. You're the only one that can affect me now. If another female is in heat, I'll be able to smell it, but I won't react. If I do get horny, I'll be searching for you." He gave her one of his cocky smirks.

"So when I go into heat again, none of the other males will come after me?" He shook his head again, letting his hand drift once more to his mark.

"No, you have my mark on you now. They'll know to stay away and anyone foolish enough to try is going to see the scary side of me." His eyes locked onto hers and he pulled her towards him, kissing her deeply. Something was still bugging her though. She pulled away, but he wouldn't let her go far.

"Alec, do you love me?"

"What?" He looked at her in confusion.

"Do you love me? I mean did you mate with me because you wanted to or because the heat drove you to?" He chuckled as he shook his head. Her innocence was one of the many things he loved about her.

"Rowan, the heat just drives us to fuck." Her eyebrows shot up at his choice of words. He drew her hand up to his mouth and placed a tender kiss on the palm before returning his eyes to hers. "The heat doesn't drive the mating. If it did there would be a lot of transgenics unhappy with their mate." She looked at him in confusion and he sighed as he tried to figure out a way to explain it.

"The drive to mate only comes when to people have deep feelings for one another. If they don't then they just screw through the heat and leave. If only one feels that way, then the mating won't take place. The feelings have to be reciprocated for it to actually have an impact." He scratched the back of his head. "I don't know if I explained that quite right?" She smirked at him.

"So what you're saying is that you do love me?" Her face inched closer to his, their lips brushing against each others as she spoke.

"Yeah," he breathed out. "I love you." He had never expected to say those words again. Not since what happened with Rachel, but he knew that even before last night, he had fallen in love with the golden haired beauty lying next to him and he couldn't be any happier about his admission.

"Do you love me?," he asked softly. Their lips brushing together again.

"Hmm?" She cocked her head to the side. "I guess you'll do." She laughed as he scowled and lunged at her, rolling her onto her back and nestling himself back between her legs.

"Guess I'm going to have to prove myself once more." He cocked his eyebrow and nudged his erect member against her opening. She moaned at the contact and he groaned as he discovered she was already wet and willing.

"I guess so." He dove to her neck and began licking and suckling on her mark. "I got one more question," she managed to get out before she let herself drown in him once again.

"Shoot," he said, not removing his head from its place.

"Am I supposed to mark you?" He pulled back and looked at her in slight shock. A playful smirk graced her face as her eyes had a mischievous glint to them. This was a different side of her and he found that he really liked it.

"You can if you want to," he said shrugging his shoulders.

"Do most of the females do it or is it just a male thing?"

"It's mostly a male thing." He watched as a slight blush graced her skin. He knew she thought she had asked a stupid question and was embarrassed. "But you know what? It sounds kind of kinky." He wiggled his eyebrows, making her laugh at the expression on his face. "I'm game if you are. In fact we can do it this round." With that his head dove back to the curve of her neck. They both laughed as they rolled around the bed before beginning their fun once again.
