His Possessive Nature

The fanfic is just like the title states. If that isn't for you, don't read. I started this a long time ago, but didn't want to post it until I finished every chapter. I finally got inspired to do so. I am trying to finish every fanfic that I have. I do not know when that will happen because I normally get my muse back in spring and don't write anything during winter.

I do not own Criminal Minds and I will never forgive them for not putting Penelope and Derek together on the show. I actually stopped watching Criminal Minds because I found it repetitive and we weren't learning anything new about the characters. They would also rarely take risks anymore. I still do love my Derek and Penelope though.

Chapter 1: Derek

When his Baby girl was shot, the world seemed to stop for one Derek Morgan. He couldn't see the rest of his life anymore without her by his side. His future would be gone if she died and he would only become a shell of himself. He always knew how he felt about her, but he was a chicken to even admit it to himself. Once he listened to all those voicemails from JJ and Spencer, he knew he had to accept it himself because he couldn't go on any longer without her. Once he got to the hospital, he waited patiently for any word on how his life was going to go on from here. When they finally found out, he was absolutely relieved that she was still alive and he planned to let his baby girl know how he felt. Until the time when she was healed, he wasn't going to leave her side. Then he would tell her his feelings for her and hopefully they would go on from there.

He knew his baby girl might be angry with him especially because the last time they talked they fought. Oh how she was wrong about him not walking across a crowded room to be with her. He would walk through a pit of snakes to be with her and he disliked snakes.

Hotch reminded him that his priority right now should be about the SOB that shot Penelope and he was glad for that reminder. He wanted that asshole to burn in the pits of hell for what he did to his baby girl. He decided to put his plan on hold for a little bit until the man that did this to his Penelope was either in a body bag or in jail. He tried to treat this like every other case, but it was hard seeing his beautiful goddess in that hospital bed. It was even harder listening to her trying to tell him about that night. He was patient with her and tried to help her as best he could. When she got worked up though, JJ and the others knew they had to leave.

After Derek's heart to heart with Reid and trying to question why, he realized that wasn't going to be helpful. What was going to be helpful was catching her shooter and putting this case to rest.

When Penelope asked for them again, Derek went inside with Reid. He still hated seeing her lying on that hospital bed, but at least she was awake and could help them more to find out who did this. So that's why he tried to treat it just like a case and put his feelings aside for now. What Penelope told them did help as they continued to question her for the four days that she was in the hospital.

When Hotch came in and questioned Garcia about some encrypted files, Derek was not happy. He tried to stop his boss, but just became more pissed as the conversation went on. Penelope could never be involved in anything bad and he couldn't believe his boss and the FBI would think otherwise.

Penelope got agitated after Hotch left and Derek tried his best to calm her down. She mentioned that everything happens for a reason and he had to agree with her rather reluctantly. If she was never shot, he wouldn't have admitted to himself how he felt about her.

He wouldn't also have found out more about Penelope's past besides the stuff he already did know. Anything about his Baby Girl though interested him and he was glad for it especially because she didn't always open up to him.

When she got the all clear from her doctor to go home four days after thanks to Reid, he was by her side and would be for the rest of her life if she would have him. He accompanied her home and helped her anyway that he could, even helping her change into pajamas. He was a gentleman though and didn't look… much. Then she expected him to leave and that wouldn't do. Of course she tried to argue, but he was very persuasive. When she turned to go into her bedroom but turned around and spoke to him instead about taking advantage of her, he knew he had to make his move.

"Hey silly girl! I love you, you know that right?" He told her honestly, but knowing that his baby girl was a little hardheaded, he would have to spell it out for her.

"I love you too." She replied.

He couldn't help his smile. "Well once you are fully healed, I plan to show you exactly how much I love you."

"Derek Morgan, what exactly are you saying?" She questioned astonished.

"I'm saying I'm in love with you silly girl."

Once Penelope got over the shock of his words, she responded. "I'm in love with you too.

The whites of Derek's teeth were showing because that's how big he was smiling after Penelope spoke. He wanted to make sure that she was right in her judgment because she couldn't take it back. "You don't have to say those words because I said them, baby girl. I know there is love between us, but you can grow in love with me."

"Derek Morgan, you have had my heart since the day you called me Gomez." She chided him.

"That's good because you have had mine since you called me eyebrows. Now go get some rest. You are going to need it for what I have planned with you." He winked at her, watching her ass sway side to side as she went into her bedroom and got into her bed. He followed her inside and sat on the end of her bed, tucking her in.

"Oh and Garcia, don't get all into your head with insecurities about us. We are perfect for each other and I love you just the way you are, curves and all. So don't you dare doubt me. Once the doctor gives the all clear, I will make sure you know what I am saying to be true only if you want me to. I won't rush you into being with me." He spoke honestly, hoping his eyes conveyed to her that he meant what he said.

"Okay, hot stuff." She smiled at him before a yawn took over her. "Night Derek."

That made him smile because she didn't question him at all, or that might have been how sleepy she was. He leaned in and placed a gentle kiss on her lips because he couldn't help himself. "Goodnight Penelope." He said before he left her bedroom and laid down on the couch. Thoughts of her kept him up that night so he could barely sleep, but that was a good fact when he heard gunshots outside. The SOB that had shot his love was back and wanted to shoot her again. He knew what he had to do, but he had to make sure Penelope was protected. He gave her his second gun and instructed her what to do before chasing after the bastard that he wanted to kill so badly. The man got away though which pissed him off. When he went back into her room, he was scared because she wasn't in the place he had instructed her to stay at. When he did find her, she was so shaken up that it killed him. He went to her quickly to console her that everything was okay. He held her for what seemed like forever until he could feel the slowing down of her heart and then that's when he pulled away from her reluctantly. "I already called in it with the cops, but I have to call the team. They should be here."

She agreed and as they waited, he kept teasing her in little touches here and there as well as some kisses to her forehead and cheeks.

The police and team arrived and then the questions started. When Rossi got a little too forceful with Penelope, Derek wanted to punch him out. It did help with the case though and they let Penelope get into the systems to find the cases that she flagged. That gave them the break in the case and find out who the guy was which made Derek very relieved.

When Penelope received something on her computer, they found out that the corrupt cop who had become an angel of death to put people at risk so that he could save them was at the FBI. Derek worried about how this was going to play out with his teammates, but his worry didn't amount to Penelope's.

They hurried to the FBI and found out that JJ was the one to shoot him thanks to Derek's phone call. Penelope was relieved to find that everything was over as she went to comfort JJ.

After Derek talked to Hotch and Rossi about his faith, he let it slip about Penelope and him. "I'm in love with Penelope and I know it's against the frat rules. I just hope that I can have your back in this because I plan on telling Strauss right now."

When he surveyed the room, he noticed a geeky tech staring at his woman. JJ had just pointed it out to Penelope and he couldn't have that. "Hey Baby Girl, we have to go talk to the section chief about our relationship." Derek yelled across the way to his girl, not caring that everyone in the vicinity heard him.

She immediately went to join them and he wrapped an arm around her. He placed a kiss on her lips, uncaring that he was doing it in front of his boss and everyone in the bullpen. He then led her to Erin Strauss' office and prepared himself for her cold and mean exterior all the while squeezing Penelope's hand to reassure her.

They knocked on the door and entered after they heard her voice. Hotch and Rossi followed in behind them because they probably wanted to diffuse the situation.

"What do you want?" Strauss said in a snide manner.

"Well ma'am, Penelope and I are in a relationship. We know it's against the FBI frat rules, but we were hoping that you could give us an exception. Yes, we do work on the same team, but Penelope is the technical analyst for our team. She doesn't always go on cases with us and despite our flirty behavior we have been able to keep it professional." He smiled at her, looking back at his fellow teammates for help if she started something.

"And what makes you think that I would be okay with this?" She asked with a raised brow.

"Well Strauss, our team has the highest solving case rate in the FBI." Hotch said to help them out. "We have all put up with Garcia and Morgan's flirting. To be honest, this won't really change a thing. I will see to it that it won't and if either of them step out of line which I know they won't from now on, I will inform you so you can react accordingly."

The section chief frowned after the BAU leader stopped speaking. She gave them all a cold icy glare and didn't say anything for a couple of minutes. Hotch, Derek and Penelope all awaited their fate while Rossi decided to try to reason with her.

"C'mon Erin, we will make sure to keep them in line just like Warner did for us." He threw a wink at her.

Strauss huffed with an appalled look on her face. "How dare you mention that in front of these three?" She pointed to the others.

"What?" David shrugged. "It's not like they didn't already know."

"Ugh." She huffed. "Fine, but if either of you step out of line, one of you is getting transferred somewhere else. Got it?"

"Yes, ma'am." Derek agreed along with Penelope.

"You are dismissed then." Erin Strauss waved them off.

They left her office and Derek turned to his boss and Rossi. "Thank you both for your help in there." He smiled at them.

"Don't worry about it. It's about time." Hotch said and gave them one of his rare smiles.

"Damn right, it's about time. I was wondering if you two were ever going to stop pussyfooting and get together. It's obvious that you two are meant to be." Rossi agreed which made Penelope blush.

"Yeah, yeah. We got it." Derek blushed as well. "I should get this one to the hospital. I'm going to be taking some of my vacation time so that I can be with Penelope as she recovers. I hope that that is okay." He asked his boss.

"Of course, I wouldn't expect anything less from you." Hotch agreed.

"Okay cool. We will see you guys later." He nodded at them with a smile.

They said their goodbyes and then as soon as they were gone, Penelope threw a hissy fit. "Do I have to go to the hospital?"

"Yes, its unavoidable mama so don't even think about it." He bopped her on the nose.

"Ugh, fine." She huffed giving in to him. "You know how much I hate hospitals though."

"I know and I promise that I won't have you stay long." He held out his arm for her and then escorted her out of the building.

The doctor didn't take long like Derek promised and she was told to rest and relax and not do any strenuous activities until he cleared her hopefully in a couple of weeks. She also couldn't go back into work until he cleared her too which Derek was fine with.

When they were in the car driving to her place, Derek decided to put another part of his plan into motion. "Alright sexy mama when we get to your place, I want you to pack a couple of bags because you are going to be staying with me."

"What Derek? No. I couldn't possibly be such an imposition on you." She shook her head.

"Sorry Penelope, but you don't have a choice in the matter. I would ask you to move in with me right now if I didn't think that it was going to freak you out. So this right now is a compromise." He smiled at her.

What he said completely flabbergasted Penelope and she sputtered, not being able to speak.

"Take a deep breath, baby girl." He coached her, glancing over at her briefly before looking back at the road.

Once she was finally able to speak, she turned to him. "Don't you think that's a little sudden Derek?"

"No, not at all." He shook his head. "We have been denying and dancing around our feelings for years now. I think it just makes sense to me. I already know how I feel about you. I love you and I want to spend my life with you if you will have me."

She took some time to think after that. "I love you too Derek, but I don't want us to move so fast and regret things later. So how about this? I come to stay with you while I recover and after I recover, I decide if I want to keep staying with you or move back to my place?" She asked him.

"It's whatever you want princess so that sounds good to me. We can go as fast or as slow as you want." He stopped the car outside of her place and smiled at her.

"Okay." She agreed.

It didn't take long for them to pack up some of her things to take to his place and Derek was happy that he was going to spend so much time with his baby. He carried her bags for her, helping her outside to his SUV. The drive to his place didn't take long. He gave his baby girl a tour and where she would be sleeping (his room) while he would take the guest room. She tried to disagree with him, but he wouldn't have it especially because he had the comfiest bed in his room. They spent the rest of the day watching movies until Penelope fell asleep. He gently lifted her into his arms and then carried her upstairs to his bed, tucking her in. He gave her a kiss on the forehead and then went to the guest bedroom to fall asleep himself.

It was around two in the morning when Derek shot out of bed at the sounds of screams. He rushed into his bedroom to see Penelope shaking with fright. "Hey Baby Girl, it's okay. I'm here beautiful. It's Derek." He spoke while slowly approaching her.

"Derek?" She spoke, her voice a little raspy from screaming.

"Yeah mama, it's me." He wrapped his arms around her, soothing her. "It's okay now. It was just a nightmare."

He stayed with her until she calmed down enough and he could feel her breathing evening out with sleep.

He shifted her slowly so that he could get up, but she wouldn't have that. She wrapped her arms tighter around him. "Stay please." She whispered.

"I'll stay forever if you will have me." Derek replied, getting himself a bit more comfortable on the bed. He then pulled her closer so that they were spooning and wrapped an arm possessively around her waist. In that position, they slowly fell asleep.

Three Weeks Later

Since the very first night they slept in the same bed, they were inseparable and spent each night together the same way. Their relationship really moved forward as a couple and they had some pretty heated make out sessions, but Derek wouldn't take it any further than that. He was being a gentleman and he wanted to wait until her doctor gave her the all clear. He knew though that he was frustrating Penelope. He was frustrating himself as well. He had a permanent erection any time that she was close to him. Cold showers and rosy palm and his five sisters were his friends currently.

He was hopeful though that Penelope's doctor visit today would yield good results and he could finally be with his baby girl. He knew that his girlfriend was hoping for the same thing.

The trip to the doctor's office was short with both of them not saying a word. He helped her inside and they took her in right away. Derek sat in the waiting room and the anticipation was too great. He didn't know how long he sat there, but the time seemed to pass by so slowly.

He sighed in relief when Penelope walked back into the waiting room with a big smile on her face. He stood up and crossed the room to her. "Good news?" He asked with a raised brow.

"Great news." She nodded, smiling at him. "I get to go back to work on Monday!"

"That's awesome baby girl." He smiled at her, but he knew that wasn't even the best part. She was just choosing not to tell him.

He rushed her to his car and sped off, wanting to get home as quickly as possible.

"Slow down my own personal Thor." She exclaimed.

"Sorry, but I can't baby." He said as he sped up even more.

She huffed, but didn't say anything further. Like the drive to the hospital, after their brief conversation they both didn't speak until Derek brought up something that was on his mind from one of their conversations earlier.

"Baby girl? Do you have an answer to my question? You are fully healed now." He asked hopeful that she would say yes.

"What question is that?" Penelope acted innocent.

"You know what question it is." He chided. "The question about you moving in with me."

"Oh that one." She pursed her lips, deciding what she wanted. "Honestly I don't think I can sleep without you cuddled up to me anymore. We've gotten really close these past weeks even closer than we already were and I think this could be good for us so yes, I will move in with you."

"Really?" He asked, wanting her to be sure.

"Yes, really." She nodded her head.

"You've made me so happy baby. Thank you." He smiled at her, wishing that he could hold her, but he couldn't because he was driving. "We can move all of your stuff into my place tomorrow and Sunday. I'll call and get some help from the team."

"No thank you Derek. You've made me so happy too." She smiled back at him. "That sounds like a plan baby."

Their conversation distracted Morgan a little bit from Penelope's news at the doctor. Once they were done talking though, he started to grow in anticipation. It seemed to take forever, but they finally got home. He parked his car in the garage and then got out, running to the other side to help Penelope out of the passenger side. Once she was down on her feet, he swung her bridal style into his arms. He then ran through his house until he reached their bedroom. Placing her gently down on the bed, he smiled at her. "The doctor cleared you for other things right?"

She nodded her head.

"Things like this right?" He swept his hand up her skirt, rubbing her center through her panties.

"Yes." She moaned.

"You know what this means baby?" He asked, keeping up his fingers underneath her skirt.

"No, what does it mean?" She managed to say.

"That now I get to show you how much I love you. Now you will see that you are mine and only mine for now until forever that is if you want me to."

"I love you too baby so much. Please show me." She whimpered.

"My pleasure." He grinned wickedly. He quickly stripped off his clothes and then started to strip her, taking his time and unwrapping her like she was a present. He started with her top and then her bra. He began to admire her for a healthy amount of time. "You are gorgeous beautiful. I can't believe that you are mine. I'm so unworthy of you."

"If anything, I'm unworthy of you baby." Penelope spoke.

He lifted her up a little only so that he could swat her butt which caused her to gasp. "What did I tell you about doubting?"

"Not to do it." Penelope looked up at him sheepishly.

"That's right. Now don't do it again."

"Okay, I won't." She agreed with him.

"You could never be unworthy of me anyways baby." He grabbed her hand and placed it on his chest right above his heart. "This only beats for you. When you were shot, I thought that I couldn't possibly go on without you. My world would dim without your brightness. My life would have no meaning without you in it. You are my world baby and don't ever forget that."

Tears appeared in Penelope's eyes and she nodded her head. "I won't. I love you so much baby."

"Good. I love you too." He smiled at her and then went back to the task at hand. He started with his hands. They cupped her breasts to see how well they fit. Then he used his fingers to pinch and roll her nipples, loving how she reacted. Then his mouth came into play, taking one of her nipples into his hot cavern and then sucking.

She moaned out when he did that which was music to his ears. If he could make her sound like that for the rest of his life, he would be one happy man.

He showed her other breast the same attention before moving on. His lips kissed down her stomach, smiling at the thought of her belly being the place that would house his children someday. Moving on, he stopped right where her skirt began. He quickly disposed of that and her panties. He knew what she wanted when she spread her legs for him. He admired her core with its glistening juices, but then decided to tease her a bit. His hands went down her leg until he reached her heel. He slowly slipped it off of her and then did the same thing with the other heel.

Penelope had enough and hit his chest with her foot. "Don't tease Derek. I have waited far too long for this dammit."

"As you wish beautiful." He spread her legs and then plunged one of his fingers into her core, curving it upwards. "Is that what you want?"

"Yes." She moaned.

When he felt she was ready, he added another one of his fingers inside of her. His digits worked her into a frenzy, but then he knew she needed that extra push so that's when he used his thumb to rub her button. She cried out then and shook with her climax. He made sure to catch her wetness in his hand while he pumped his fingers still until her aftershocks were over. He raised his hand up to his mouth and made sure to lick every last drop of her essence. Her taste was a combination of sweet and sour that he loved and wanted more of.

He dove right into her core, not giving her any chance to recover from the orgasm he gave her with his fingers. By the end of the night, he hoped that she would have plenty of orgasms because otherwise he didn't do his job right and he couldn't have that.

This is where his possessive nature came into play. By the end of the night, Penelope would know who she belonged to. He would make her scream his name over and over until her voice was hoarse from use. He would make it so there was absolutely no doubts left in her mind at all about his intentions and the love he had for her. He'd make her his because he was already hers.

He licked, sucked and flicked his tongue against her pussy and clit making it so that her orgasms crashed into one another. He started spelling out the alphabet first and then once he was done with that he spelled his name out on her button. She screamed and moaned with all the pleasure he gave her, but when it became too much, she had to crawl away from him.

"No more." Penelope panted, not even sure how many times he had brought her to orgasm with his mouth.

"I'm not done with you woman." He growled.

"Let me catch my breath first please."

"Fine." He huffed. He moved up to lay besides her, watching as she calmed down from all the highs he had given her.

When he felt she could handle it, he ran his hand up her leg to her core to find that she was still wet. "Damn baby." He moaned, fingering her. His erection was already seeping from watching her moan and writhe with her many climaxes. He couldn't wait any longer. He had to make love to her.

"Derek, please." Penelope moaned.

"What do you want baby?" He asked, still keeping up the rhythm of his fingers.

"I…" She bit her lip with a little apprehension. "I want…" She moaned when he curled his fingers up to hit a spot in her that she didn't know she had. "I want you inside me now."

"Your wish is my command baby." He removed his fingers and used her juices coating his hand to rub his dick a little. He moved on top of her and then slowly inch by glorious inch moved inside of her. "Shit baby. You are so tight."

"Oh, fuck." Penelope whimpered a little in pain.

"I'm sorry baby." Derek said once he had bottomed out inside of her. He kissed the few tears away that had sprung to her eyes, hating to see her in so much pain. He didn't move inside of her, not wanting to hurt her further.

When the look of pain on her face was replaced by pleasure, Penelope urged him to move which he happily complied. He started out slowly to get her used to him, but he was finding it hard each and every time not to pound into her.

"Umm… baby boy?" Penelope said between moans. "Are you wearing a condom?"

"No, I'm not baby. I am clean and I can give you the doctor's note to prove it. I know that I should protect you, but I know that you are on the pill. It's just that ever since I lost my virginity, I always wrapped up my dick. With you though, it's different. I don't want to. I don't want there to be that barrier between us baby. I love you too much for that. Please forgive me." He stared into her eyes.

"I believe you and I'm clean too Derek. I am on the pill baby. It takes two to tango and this feels way too good for you to stop. I don't want that barrier between us either and you can always pull out." She chuckled a little, winking at him. "There is nothing to forgive my chocolate Adonis, but there will be in a little bit if you don't go faster."

"As you wish." He exclaimed before taking heed of her words. That was all he needed to start ramming inside of her, the beast in himself awoken. He wrapped her legs around his waist so he could sink into her a little bit more with his strokes. Her breasts then were calling his attention so he leaned down and latched onto one of her nipples, sucking hard.

"Shit, Derek!"

He moved to her other breast and did the same, making her exclaim his name again.

"I'm so close baby boy."

"How badly do you want to cum baby?" He grunted, still moving his hips in a frantic pace.

"So badly." She whimpered.

"Tell me. Has anyone else made you feel this way?" He asked as he thrusted inside of her.

"No, only you." Penelope moaned.

"Only who? Say my name baby." Her chocolate god commanded of her.

"You Morgan!"

"Say my first name baby."

"DEREK!" She screamed, milking his dick with her juices as she came.

His strokes never ceased. "Whose pussy is this?"

Penelope didn't reply too overwhelmed by her pleasure.

He pinched her clit. "I asked whose pussy is this. Now answer me sexy mama."

"It's yours." She screamed again, sent over the edge once more by him pinching her button.

He grinned at her words and then finally allowed himself to join her in bliss after a couple more thrusts. He spurted his seed inside of her womb, coating her walls. He slumped on top of Penelope once he was done, careful to not crush her with his weight. He didn't want to part from inside of her, but he knew he must. He slowly retracted from her and then flopped on the other side of the bed. "Baby you okay?"

He turned to her, but then chuckled when her answer was some soft snores. He definitely wore his baby girl out. Curling her into his side, he decided to follow her into dream land.

It was hours later when Derek woke up to soft kisses all over his face. "Mmh, that feels nice." He blinked his eyes open to see his baby girl hovering over him. "Someone I see is raring to go." He chuckled, but immediately got turned on at the sight of Penelope's naked body.

He saw Penelope's eyes go to his erection and she licked her lips. "Just like you are mine baby, all that I am is yours. Especially this." He grabbed her hand and placed it on his erection. "It's yours to kiss and show you pleasure any time that you want it."

"Really?" She asked as her hand started to rub his erection up and down.

"Yes baby." He nodded his head.

"Good." She smiled at him. Moving down on the bed, she became eye to eye with his erection. She started by licking the vein on the underside of his cock with her tongue before she took him into her mouth.

"Shit baby." He loved the feel of her hot wet mouth on his dick. She hollowed out her cheeks to take a little more of him inside of her and then when she moved her mouth back up she sucked on his tip. A couple of more moves like that and he would be ejaculating into her pretty mouth which isn't what he wanted.

"Baby Girl. Baby Girl stop. I want to be inside of you. Don't you want me inside of you?" He asked as he stilled her movements.

She released him from her mouth and nodded.

"Hop on board then." He smiled at her.

She straddled his thighs and then aligned herself up with his dick. Slowly sinking down on him, she took her time until she was fully seated.

"God, you're so fucking tight baby." Derek groaned, grabbing her hips to start the rhythm between their bodies.

With every thrust, he made her his and him hers in body, mind and spirit for that night, that morning and the rest of their lives if only everybody else would get that memo.
