This idea has been pissing me off for a while and I needed a break from High School (don't worry, there are still updates to come! Hope you don't mind a really long story because I just looked at the plan and I'm not even half way through). Anyway Enjoy!

Letting Go

Chapter 1

Peter held her close as her body moved with his. Beginning as slow and loving and moving to fast and hard, just like she wanted, just like she asked. He would do anything that she asked and right now, he wasn't complaining. Her fingers bit into his back as her long blonde hair sprawled out over the pillow below her, the bangs brushed to one side and stuck to her forehead.

He needed her, like he needed air. He missed her more than he could have thought and now she was back by his side. "Oh Peter!" the words he dreamed about for so long were coming from her mouth again and she was finally his. She was never walking away from him again and he was never going to let her go.

He moved inside of her, deep, hard, pleasurely painful. She whimpered, cried and held on to him. His groans mixed with her moans as the world around her began to crumble. He could feel her orgasm coming, the tightening around him, the fingers digging deeper into his skin, the sharp pants and deep breaths. She was coming and he was going to follow. "PETER!" his name bounced off the walls of his bedroom. They had moved on from hers and into his. It felt better, more like a family. With Walter in the house (not that Walter was there now). Waking up together and having breakfast and going to work, it's what he wanted and what she wanted and it was all theirs.

Peter tipped over the edge as she came down, thrusting, once, twice before spilling into her. He didn't slow as he finished, riding out both their orgasms longer. Holding her close as he slowed, he leaned down and placed a gentle kiss onto her forehead. "I love you sweetheart" he stayed inside of her as she clung to him, she never seemed like she wanted to let him go.

Olivia Dunham, his Olivia Dunham, haunted and darker in the eyes, was his. And had been for the last 3 months. They had been at odds for more than 3 months before she thought he was dead and when he had come back one night, she couldn't, no wouldn't let him go again.

"I love you Peter." she whispered, it was still something she had trouble with, growing up in a broken home but when she did say it, Peter was over the moon. He pulled out of her slowly, prolonging the feeling of actually being inside of her, pulled her onto his chest as he rolled to the side. "sleep sweetheart." Peter kissing her forehead but she was already asleep.

~**~

The last month had been hectic, Olivia and Peter were arguing about cases, suspects and how to deal with the impending doom that awaited them.

"You never listen to what I have to say! Why do you have to be so stubborn?" Peters voice rose and echoed through out the lab. Walter and Astrid looked up to find Olivia walking out of her office, red faced, while peter followed, seemingly fuming." Olivia damnit! Stop!" Peter grabbed onto Olivia's arm, causing her to turn around, "Would u just listen to yourself for a moment? Please?" his voice softened, "You are talking about overdosing on Cortexiphan and get into a tank that will kill you before going back over there, where you don't have anyway of contacting us or getting home. I don't want you to do this. Please. I can't lose you again sweetheart." she looked up at him and waited before answering, "Peter we have no idea what is going on over there, this could be the only way of finding out...and don't call me sweetheart!" Olivia turned on her heels and Left him in the lab, slamming the doors on the way through.

Peter just shook his head and walked back to her office and slammed the door. It wasn't an unusual fight, and it wasn't the only one they have had, but every time Olivia would be back at home with Peter curled up by his side, telling him how she feels. She would always come home to him and he would always go home to her if it was something he had said.

"Agent Dunham" Broyles had showed up at the lab the next day. Peter and Olivia were sitting together, closer than most partners would be, but he didn't care. They looked up to find him watching them, "Sir?" he nodded towards the office and they made their way in. "Agents, there has been a development, at around 11.30 there is set to be another door open and we are expecting other to come from it, I want you all there." The last week and a half, doors to the other side have been opening up and every time 3 or most shape shifters had come through and each time, Peter, Olivia and a small force of agents had blown then straight back to where they came from, using any form of weapon they could find. Peter and Olivia nodded, left and suited up for the long night ahead.

Each night, like the one coming, sent Olivia and Peter home needing comfort and each other. Their love was passionate and fierce left them more in live than before.

Standing in their bedroom, she had officially moved in 2 months ago, Olivia stripped of her work clothes and pulled on the ripped jeans she had chosen for these days. They were comfortable and easy to move in. Standing in the middle of the room, Peter came back in and dropped the black duffle bag on the floor.

He watched her standing in the middle of the room, half dressed, jeans and a bra and he smiled. They both knew they weren't going to be with anyone else and Peter figured it'd be for the best, he was able to get this nagging question off his chest. He grabbed onto her arms and pulled her in for a passionate kiss, one that was reenacted every time they had to go out like this, but once it was over, he didn't pull away. "Marry me." The words were quiet and sweet. Olivia pulled away. "What?"

His hand reached into his pocket and pulled out a solitary diamond ring, "Well?" He smiled at her while he waited, he knew she was debating on whether to say yes. He reached for her hand and slid the ring on gently. "Olivia, I have known for longer than I would have liked that I love you. There is no way I would want to spend the rest of my life with anyone else. Marry me." She waited a moment before smiling. "Peter I know we have only been together for 3 months but we have been through more together than anyone else ever will. I could never see myself with anyone else." She smiled again and pulled him down into another passionate kiss.

"Come one. We have to go."

The arrived at the site just before 11.15. Walter and Astrid had met them their, as well as the team that would be firing at whoever or whatever came through the door way. "Peter are you sure this is a good idea, something seems of about this…" Olivia was stand next to Peter, the look in her eyes telling him more than what she was going to tell him. He turned to have his back to the possible doorway and pulled Olivia closer to him.

"Livia, I promise whatever it is, we will deal with it together." He held her closer and placed a kiss on her forehead. Just as he was, the door opened, the wind picked up, leaved swept around the pair but neither paid attention, for once completely wrapped up with each other. Within moments there would be the sound of gun shot and then they would be able to go home and celebrate their engagement.

Moments passed and nothing happened, it wasn't until a voice echoed in the silent forest that Peter and Olivia turned around. "Hello Peter." Swallowing the sudden lump in his throat, he turned around and was faced with her. Altlivia had returned and she wasn't alone. "You remember Charlie, and this is Lincoln." She motioned to the men standing behind her, both holding their guns pointed at Olivia and Peter.

"What the hell are you doing here?" Peter unconsciously stepped in front of Olivia. "Oh looks like he chose you." The cruel smirk on Altlivia's lips shone in the spotlights. "There was no choice!" Peter growled back. Altlivia's smirk grew. "Peter you need to come back with us." Her voice softened, hoping he would remember what they were like before. "Why would I go anywhere with you?" Olivia had stepped out from behind him, just watching the way her alternate was with Peter. "Because baby, if you come with us, we can spare your universe and mine." Peter let out a chuckled, "And what makes you think I will believe that?"

Olivia spoke up, Peter turned to face her, "Because none of them would have been allowed or even wanted to come over if it wasn't true. Isn't that right?" Olivia now watched her alternate with a different interest. "Peter go." Her voice was quiet. Peter spun on his heels, in complete and utter shock that she would have suggested such a thing. "I'm serious Peter, go."

"Livia, you can't be serious. Baby come on, this isn't the way." He was directly in front of her now, both his hands resting on her cheeks, making her face centered with his. "Baby no. We'll work something out together, that was the point of this, together remember?" he dropped one hand to her left and brought up the sparkling diamond ring. From behind them, Walter and Astrid gasped, neither knew of the engagement. "Peter, listen to me. I love you more than anything but this could be the only way to stop this from happening. I don't want you to go but this could be it." Tears were now streaking down her cheeks. Peter dropped his hands and took a step away from her, confusion and anger rolling off him in waves.

"You think I'm letting you go now? After I only just got you back?" he dropped his gaze and looked up once more, he saw the pain in her expression and the tears, "Baby, I don't want to go." He reached for her once more, this time taking both her hands in his. He knew she was right, he just wished she wasn't. He glanced to the side and saw that Walter was in tears and Astrid wasn't much better. HE let go of Olivia and walked to Walter, "Is there another way?" Walter said nothing, just kept crying, "Walter! Please tell me there is another way."

Walter took in two or three large breathes before answering, "Not that I have found yet Peter. It's getting worse." He embraced his father in a bone crushing hug, Walter's sobs raking his body, Peter's own tears falling. "I love you son." His voice broken and in heartache. "I love you too dad." Peter reluctantly pulled away from Walter, intent on moving to Astrid, who didn't want to be hugged, she pushed him away as hard as she could but he was able to get his arms around her and pull her into a hug.

No words were spoken as he pulled away and turned back to Olivia. Her arms locked themselves around his neck and his held her tightly. His tears had multiplied as he saw the heartbroken look in his lovers and fiancés eyes. Her sobbed echoing into the darkness. He tried to pull away, her hands clenching to his collar. "Livia, I love you forever. Please baby, we both know this is the only way." He was able to get her hands away from his collar but instead of leaving, he pulled her in for a passionate and forceful kiss. "Keep the ring baby. I love you." He pulled away from Olivia and turned his back, not trusting himself to walk through the portal if he saw her once more.

Taking his position next to her alternate, Peter finally turned and saw that Olivia was hanging on to Astrid, trying to get to Peter. Astrid was holding her back. "Lets go!" Charlie's voice broke the silence and he and Lincoln took a few steps and disappeared through the doorway. As Peter turned his back, intent on walking through with Altlivia, Olivia's voice rang out, "Peter!" he turned on his heels and watched in slow motion as she was able to push Astrid off her and she ran over to him. He met her halfway and the embraced like dying lovers. "I don't want this to be the way. I can't let you go." She sobbed into his ear.

It broke his heart to hear her words. "I'm not saying goodbye Olivia. I'll never say goodbye." He kissed her one last time before ripping himself from her arms and walking straight through the doorway, Altlivia disappearing shortly after.

Olivia collapsed to the ground sobbing and wrenching, Astrid was at her side in seconds, her own sobbing mixing in with Olivia's. Walter had slid down the nearest tree, head in his hands and his own tears plummeting down his cheeks.

No one seemed to remember the small team of agents watching the heartbreaking scene in front of them.
