This one is for Morgan & Gina (k_morgaan & JoyfulGina on Twitter), they came up with the concept and Mairym (Bensidy_Lover03 on Twitter) helped me work out a few of the details. TWO UPDATES IN TWO HOURS HOLY HANNAH. Now... enjoy!

The door clicked shut and Brian walked into the living room, seeing Olivia and Nick talking. "Hey babe."

She smiled up at him. "Hey."

Brian looked at Nick. "Hey Nick, how are you?" He was met with silence. "Your daughter? I heard about the shooting."

He refused to look at Cassidy. "She's shaken, but fine."

"That's good." He met Olivia's eyes and squeezed her shoulder. He saw her smile up at him. He walked into the bedroom.

Olivia looked at Nick and smiled gently. "Let me know if you need anything," she said softly, standing up and walking into the bedroom, closing the door behind her.

Brian walked over to her, and wrapped her tightly in his arms. "You sure you're okay," he whispered.

She sighed. "I'm fine, Bri. Really." She smiled, looking up at him.

He kissed her lips. "I could have lost you today. It brought me right back to last spring, that knot in my chest when I found out you were gone. I hate that feeling."

"You think you can get rid of me that easy? You're stuck with me baby, forever." She wrapped her arms around his neck. "I love you."

"I love you more."

"I never win that fight," she whined.

"Not with all the sass and wit in the world, baby," he whispered. "I would die for you Olivia, if it meant saving your life. I would kill for you. I would do anything for you."

She smiled and nuzzled against him. "I'm fine baby, I'm right here, I wasn't hit. I'm not going anywhere." She caressed his face. "I would do anything for you; I love you with everything I have, every fiber of my being, you're engrained in me." She tilted her head gently, staring into his hazel eyes.

He caressed her face, her eyes closed and nuzzled into his hand, letting out a soft sigh of contentment. He lifted her chin with his finger and looked deep into her eyes, kissing her gently, running his hands down her body, gripping her ass.

Olivia moaned and pulled back, feeling his lips on her neck. "Baby, Nick's right outside."

"We can be quiet," he whispered against her lips. "We've done it before."

She gently bit his shoulder. "If he hears us…"

"He can knock on the door or he can come in and watch for all I care. All I know is that I need you tonight, I don't care if the fucking Pope is sitting in our living room."

She looked at him. "You'd want Amaro in here watching you and me, while I was naked," she raised an eyebrow and crossed her arms.

He smirked and smacked her ass gently. "Let him watch all he wants, cause you're all mine."

Her mouth fell open and she smacked his chest. She started to chuckle. "You're a pig, you know that."

He shrugged. "I've been called a pig a few times, both for being my charming self and for being a cop."

She rolled her eyes. "You're incorrigible, Brian Cassidy."

"But you love me," he said in a sing song tone, kissing her temple.

She smiled and wrapped her arms around him, her head resting on his chest, her eyes closed. "More than I could ever possibly describe."

He rubbed her back, kissing the top of her head. "I really need you tonight, baby. I need to feel you," he whispered.

She smiled and looked into his eyes. "Well, I kinda need you tonight, too," she whispered back. "I really do." She caressed his face. "I'm yours."

He leaned in and kissed her passionately, pulling her close. They quickly shed each other's clothes and moved to the bed. He climbed on top of her and looked down into her eyes. "You're so sexy, so beautiful."

She smiled and kissed him again, letting out a gentle moan, feeling him push inside of her. "Fuck," she whispered, arching her back.

He chuckled. "Quiet never has been your thing, has it?" Her eyes were squeezed shut and she shook her head, biting back a moan. He kissed her neck and whispered in her ear. "Bite me, if it'll drown out the noise."

She bit on his shoulder and let out a soft moan, feeling his hips start to move. "This is torture," she whispered, covering her mouth and moaning. "I need you to move faster baby," she whispered.

"I know, but you need to stay quiet so Amaro doesn't hear us."

She let out a frustrated groan and flipped them, straddling him. "I'm gonna ride your dick baby, ride you hard." She started riding him fast and hard, her moans breathy and quiet, until he hit a particularly sensitive spot inside of her and she let out something between a strangled moan, grunt and squeal. She clasped her hand over her mouth again but only for a minute as she continued riding him.

Amaro, being the detective he is, heard her groan of frustration and he stood up, walking to the bedroom, trying to hear anything else to be sure she was okay. That was his partner. When he heard this noise he'd never heard before he got worried and quietly opened the door, to assure she was safe and didn't need any help. He still didn't trust Cassidy as far as he could throw him.

What he saw as enough to knock the wind out of him. He saw his partner, naked, on top of her boyfriend, riding him. He felt himself get hard and he growled internally. He was stunned. The sight before him was so sexy he didn't want to look away. He saw Cassidy look over at him and he quickly shut the door, looking around the apartment. "Holy shit," he whispered, walking to the couch, sitting down, desperately trying to get the image of his partner fucking her boyfriend out of his mind.

Olivia heard the door latch and she stilled. "What was that?" she whispered, looking at the door then down at Brian.

He looked up at her. "I didn't hear anything."

She smiled and leaned down and kissed him passionately, starting to ride him again, moaning into his mouth. Within a few minutes they were both coming, clinging onto the other for dear life. When they finished she rolled off of him, letting out a gentle moan, feeling him slip out of her. "That was incredible."

"I love it when you take control, baby," he whispered.

She smirked. "I like it too." She nuzzled into him, wrapping them in the blankets on their bed. "You don't think Amaro heard us, do you?"

Brian saw Amaro looking at Olivia. He knew what Amaro heard, but he also knew that if Olivia knew that she would be mortified. "No, you were actually very quiet. Didn't think you had it in you. You're usually a screamer, baby."

She chuckled. "Only for you, baby," she whispered. She kissed him gently, looking at the clock. "We have an early morning, we should get some sleep," she smiled and kissed him again. "I love you."

He kissed her back, wrapping her in his arms. "I love you too, Liv," he whispered, his arms wrapped around her as she buried her head in his chest, and they fell into a peaceful sleep, not waking until the alarm went off.

Olivia groaned and pulled him back to her when he rolled to turn the alarm off. "No, stay," she whispered.

"We have to get up, babe."

She shook her head. "Sleep," she whispered, trying to convince both of them to stay in the warm confines of their bed.

"We need to at least offer Amaro breakfast," he murmured.

She groaned. "Fine, I'm up." She sat up and looked at him. "Morning," she whispered, kissing him soundly on the lips.

He smiled and kissed her back. "Good morning, Sunshine." He kissed her temple. "Come on; let's get some clothes on that sexy body. Don't need Nick seeing my sexy girlfriend naked," he winked.

She smirked and put on her panties and a pair of tight yoga pants and a tank top. "I'll go start the coffee, you get some pants on. Don't need Nick getting jealous," she whispered, kissing him softly. She walked out of the bedroom, seeing that Nick was already awake. In fact it didn't look like he'd slept. "Hey, partner, you look like hell."

Nick hadn't slept. He couldn't get the image he saw last night out of his mind, Olivia's head thrown back and her mouth open in a silent moan as she rode Brian like a bucking bronco. He averted his eyes. He couldn't look at her. His face was flushed. "Yeah, a lot on my mind."

She furrowed her brow at him, but figured it was probably nothing. He did have a lot on his mind, he was under investigation for shooting a boy, and his house was just shot up last night. "You want something to eat, some coffee?"

Everything sounded dirty to him, and he needed to get his head right. "No, no, I'm good. I think I'm just going to get dressed and head into the precinct."

Just then, Brian walked out and wrapped his arms around Olivia from behind, gently kissing behind her ear. "Hey babe," he whispered, and looked at Nick. "Nick," he nodded.

Nick looked at the floor and nodded, rushing off into the bathroom to change and relieve the throbbing erection he'd been trying to get to go away since Olivia walked out of the bedroom. Olivia looked at him and then at the shit eating grin on Brian's face, and she knew. Nick saw. She smacked Brian's chest. "Why didn't you tell me, you ass!" she scolded quietly.

"Because, you didn't see, I know you're shy about other people seeing you naked."

"Brian, I have to work with him, it's something I needed to know!" she said, crossing her arms, running a hand through her hair. "When, what did he—"

"When you were on top."

"Oh God," she closed her eyes and gripped the counter. "So he saw me, no wonder he won't look at me." She shook her head. "Um, I'm going to go shower. I'm not hungry." She walked into the bathroom that was off of their bedroom and turned on the water.

Nick walked out of the other bathroom and looked at Brian. "Um, I'm heading into the squad room."

Brian sighed. "Nick."

He put his hand up. "No, it's fine. You're a lucky man," he said and nodded, grabbing his coat and putting it on as he walked out the door.

Olivia quickly showered and got ready for work. She walked out and looked around. "Where's Nick?"

"He left for the precinct."

She closed her eyes and nodded. "Look, next time you notice one of my co-workers sees me naked, whether we're having sex or not, could you just tell me?"

Brian wrapped an arm around her and kissed her temple. "I'm sorry, I thought I was doing the right thing."

She nodded. "I know, I just now have to deal with Detective Awkward all day and I don't exactly know how to handle it."

He looked down at her. "Well, for what it's worth, he thinks you're sexy."

She looked up at him. "He told you that?"

He shrugged. "Not in so many words, just told me I was a lucky man, but I already knew that."

She smiled. "I love you. I need to get going, and you need to get ready and get to work." She kissed him gently. "I'll see you later, I love you, I love you, I love you," she whispered and kissed him passionately, only holding the kiss for a moment before pulling away, grabbing her keys and her coat and heading out the door.

When she arrived at the precinct she went to the coffee pot, making herself a cup. She looked at Nick and looked around. "Look, Amaro, about what you saw last night—"

He cut her off, holding up a hand. "No, I never should have opened the door without knocking."

Olivia smiled. "I mean, we're adults, the door was closed. You could have knocked," she teased. "I never meant for you to see that. I hope we can put it behind us. And I promise Brian and I will lock the door if we decide to do anything while you're there."

He nodded. "It's forgotten, and I beg you to keep that promise."

"Gee thanks."

"Nah, I just don't need to see a full frontal view of Cassidy. You… Wow."

She blushed and bit her bottom lip. "Thanks, Nick," she whispered, taking a sip of her coffee.
