Peter woke feeling enveloped in warmth with silky soft hair spread across his chest. He lay still, recalling their wild and activity filled evening and nearly groaned out loud. His body was already feeling achy and thoroughly used up, but it wasn't an altogether uncomfortable feeling either. Olivia's head was resting on the spot between his shoulder and chest and she had her right leg entwined with his legs. Her right arm was spread across his torso and held him snug against her. Peter couldn't help but smile at how wonderful this felt, to just be in a bed with this woman. He watched her eyes flutter in her dream state and how her mouth was just slightly parted. Peter was sure he could spend every morning for the rest of his life like this and that particular thought made his heart almost leap out of his chest. Did he really just think that? Did he love her? He knew he'd had strong feelings for her. The need to care for and protect her was overwhelming at times and he was always trying to make her laugh or smile. For the first time in months the urge to run was almost all consuming. But he forced himself not to move. He looked down at Olivia whose eyebrows knit closely together as she pulled herself closer to him. She murmured something he couldn't quite hear but she was whimpering in pain now and Peter couldn't stand to watch. He leaned down and gently placed several kisses on her brow and whispered her name.

She jolted awake and Peter held her close.

"You're safe, 'Livia." He murmured into her hair and she held him as if he would disappear in her arms if she didn't hold him tight enough. He ran his fingers through her hair and rubbed small circles on her bare back with the other hand. After a few minutes her body released the tension it had been holding and she looked up at him.

"I-I'm sorry, Peter." She whispered, trying to hide the morning scratchiness.

"You have nothing to be sorry for," and leaned down to kiss her lips softly. He felt his heart flip and he pulled back slowly. Her eyes looked a little dazed after the kiss, but when they refocused it was behind him.

"Oh no!" She jumped out his arms and bed and began dashing around the room for clothes but couldn't find any.

"What's wrong?" Peter asked, clearly alarmed.

"The time! It's 11 already!" She tore the sheet from around his waist and wrapped it around her.

"So then it's about time we get back to bed?" He grinned and made his way toward her.

"No, Peter, 11 in the morning!"

He froze and turned to stare at the clock. "Shit!" He was running around the room in a flurry, throwing on some clothes from his dresser. Once he was decently covered he turned to her. "I'll go collect our clothes. I wouldn't want Walter to die of shock upon seeing that lovely body of yours." He winked and ducked the pillow she threw at his head. He'd only just made it out the door with it shut behind him when his father was standing just two feet in front of him.

"Peter!" Walter said excitedly. "Is this a ladies brazier?" In his hand dangled Olivia's bra and he knew Olivia could hear their interaction and almost laughed. He quickly snatched it away from his father and gave him a stern look. "Is it Agent Dunham's?" He asked almost bouncing on his heels. This time Peter did hear her groan in despair from the other room.

"That," he said pointedly, "is none of your business, Walter." He passed by his father and quickly gathered whatever clothing he could find and retreated back to the safety of his bedroom.

"Say hi to Olivia for me!" Walter almost yelled through the door, causing Peter to shake his head.

Olivia was sitting on the end of his bed, still wrapped in his bed sheet. He could see a lot more than she probably wanted at the moment and he debated on just taking her back into bed and repeating last night all day today. She noticed the change in his stature and gaze and glanced down to see him very ready.

"Peter…" Her voice was breathy with lust and she was up and taking the two long strides to close the distance between them. He dropped the clothes to the floor and quickly wrapped his arms around her waist and kissed her like she was his air. Her nimble fingers made quick work of his pajama pants and then he was naked again. She suddenly didn't care that Walter was on the other side of the door; she just needed to feel Peter inside of her again. Gripping his butt she pulled him closer to the bed as they continued to kiss and rub their bodies together.

Though it was the hardest thing Peter had ever done, he pulled away and stopped their progress to the bed. "'Livia, we have a case that we need to see to. As much as I want to spend all day – hell, all week, in bed with you, we really need to get ready."

She shook her head and latched her mouth onto his and kissed with every ounce of passion that was built up in her body. He groaned and returned the kiss with equal fervor, but then pulled away a minute later.

"Let's at least multitask and use the shower." He offered.

Olivia nodded that it was a good compromise and they rushed into the shower, giggling and laughing.

They finally escaped the confines of the bedroom around noon, Olivia wearing one of Peter's MIT t-shirts and the jeans she had worn over. Apparently her button shirt was beyond the help they had at the moment, but Olivia wasn't going to complain. The shirt of his she was wearing smelt like him and she had to stop herself from lifting the collar up to her nose to smell it. Peter had done a recon on the small house and discovered a note from Walter saying that Astrid had picked him up and taken him to the lab and he would hopefully see him there later if he could bear to part with his new playmate. Sighing he told Olivia where Walter was and they headed out to the car. Olivia still felt warm so she forwent the proffered jacket that Peter almost forced her to wear and relished in the feeling of the freezing air touching her bare arms and neck. They drove over to her place and Olivia convinced Peter to wait out in the SUV while she traded clothes. When she got into her place Rachel and Ella were in the middle of a game of dragons and princess; a game Ella had invented where she was the princess and Olivia and Rachel were dragons let loose to drag her back to the tower. Smiling, Olivia snuck around the furniture to catch Ella by surprise and scooped the girl up into her arms and tickled her senseless.

"Aunt Liv!!!" She giggled and squirmed in her grasp before she finally let the girl down to scamper off to a new hiding place. Rachel was staring at Olivia with a knowing smirk and raised eyebrows.

"What?" Olivia asked suspiciously.

"Nice shirt," she smiled that cocky knowing smile that said she knew what was going on. Olivia's first reaction was to deny it; there was nothing going on but then her mind flashed back to some of the things they had done and she found herself turning red instead. "I knew it!" Rachel squealed with glee. When Olivia didn't respond except to turn more red and attempted to side step her to get to her bedroom, Rachel stepped in front of her. "I don't think so Livvie. How long have you guys been going on now?"

Olivia frowned. Had it been that obvious how she felt about Peter before now? "Just yesterday, actually."

Rachel's jaw dropped and in her shock Olivia snuck past her and into her bedroom, locking the door behind her. Resigned to her sister knowing, Olivia went about getting ready as efficiently as possible, grabbing a white blouse, black jacket, and black slacks. She clipped the badge onto the front of her hip in her waistband and then tied her hair up into a pony tail. She was already feeling more like herself and she smiled. Ready to take on the world, or at least her sister, she left the safety of her bedroom and practically sprinted to the front door without actually running. She breezed by Rachel who had her mouth open and ready to ask Olivia the million questions she no doubt had, but Olivia interrupted her as she made haste to the door.

"Gotta case, talk to you later!" And she was out the door and running for the waiting vehicle. She climbed in and smiled at Peter. He returned the smile and they sped off.

The next few days were much like the last as Peter and Olivia worked cases during the day, but when they were done they would spend entire evenings taking turns between extreme amounts of sex and short naps. When the fifth day was upon them they both tiredly admitted that a night off would be nice.

"I did tell Rachel and Ella I would do something with them sometime this week." Olivia said as they were leaving the lab. Peter nodded.

"I'm sure Walter would probably appreciate it if I showed my face at the house a bit more." Peter was secretly excited to be getting an entire night of sleep, but he would miss Olivia. He felt foolish because up until four nights ago they had functioned just fine apart, but he felt an ache at the thought of being apart from her.

Olivia wanted a reason for them to be together that night, but she needed the time off from him to think things through and rest. It wasn't that she doubted them, but she's never fallen for anyone this quickly and thoroughly. A night with the girls was exactly what she needed. When they got outside Olivia shivered and she wrapped her arms around themselves. She could feel the cold again and her jacket was at home. Before she could even think of a solution she felt a jacket being draped over her shoulders and she looked up into the smiling eyes of Peter.

"Aren't you going to be cold?" She asked.

"Maybe, but I'm just glad to see your body temperature is coming back down to normal." He said, wrapping an arm around her waist as they continued to walk towards their respective vehicles. When they got to her car door, Peter spun her around slowly to face him so that she was between him and the car. Peter had already admitted to himself that he was head over heels in love with her, but he didn't think she was ready to hear it, so he poured it into a deep and slow kiss that stole her breath. She leaned into his body and drank in the taste of his lips. When they pulled apart for air Olivia's eyes were lightly shut, trying to remember this kiss until their next.

"I think if I'd have known you were this great of a kisser we might've hooked up a lot sooner." She murmured.

Peter chuckled, "is that so?"

She opened her eyes and stared into his. "Yes, I think so." She smiled up at him and Peter's heart flipped in his chest. It must've been written all over his face, but she either didn't see it or was blind.

"Well, give me a call if some unexpected free time pops up," he said slowly backing away from her.

She nodded and then leapt forward to hug him one last time; to breathe in his scent so that she could keep it for awhile longer. He chuckled and rubbed her back.

"I'm starting to get a bit cold now, so, I'll talk to you later." He released her and turned towards his car.

She watched him get into his car and drive off and she decided to do the same.
