Chapter 4

"Where are we?" Elliot called out as he and Olivia entered the precinct. Cragen turned around, surprised to see the two of them there. He looked at Olivia.

"I can do this Captain," Olivia assured him. Cragen looked over at Elliot who nodded his head in agreement with Olivia's statement.

"Fin?" Cragen called out.

"Cayden, 11 years old, missing since this morning. No criminal record, no school records, no hospital records except for a birth certificate," Fin said as he handed Elliot the missing persons report and Cayden's birth certificate.

"Nothing?" Elliot asked.

"I think the boy was a prisoner in his own house," Munch said, "but Mom is in the wind. I don't think we're going to get anything out of her anyways."

Elliot handed the papers to Olivia after he skimmed over them. "Liv and I went over that house top to bottom, there was no sign of any other children living there," he said.

"Well, the search warrant just came in. Head over there and see what we missed," Cragen said as he held up the folded piece of paper.

Elliot took the paper from Cragen and they all headed out to the car.

"What the hell?" Fin said after they had searched the house. They were standing in the living room, none of them had found anything.

"Are we even sure this kid exists?" Munch asked. "Or is the mom just screwing with us?"

"He exists," Fin said. "We got his birth certificate."

"Wait a minute," Olivia said. "Have any of you seen a dog?"

The three detectives looked at Olivia, wondering what she was talking about. They shook their heads.

"Nope, no dog," Elliot told her.

"Then why is there a doghouse in the backyard?" Olivia asked, pointing at the back door.

The four of them headed out back and Olivia leaned down to peek into the doghouse.

"Son of a..." Olivia quickly stood and hurried off. Elliot, Munch and Fin all looked into the doghouse.

"I'll call Warner and Cragen," Fin said.

"How old do you think she is?" Munch asked Elliot.

"She can't be more than a year," Olivia said, rejoining the group after throwing up on the side of the house.

"Wait a minute guys," Elliot said. He was kneeling in front of the doghouse. "Somebody was living in here. There's a blanket, a pillow, some food wrappers and a baby bottle. I don't think this is just a dump site for the baby."

"What if Cayden was living in here with the baby?" Fin suggested.

"Could be," Elliot said standing up. "The blanket is spread out neatly and the trash is all tucked away in one corner. It's kind of organized, as organized as a dog house can be." Elliot said.

"This is absurd," Olivia said shaking her head.

"You can say that again," Munch said. "I wonder where our mother of the year disappeared to."

Munch and Fin headed back to the precinct to put a BOLO out on Jennifer Hughes and attempt to track her down. Elliot and Olivia waited for Cragen, Dr. Warner, and the crime scene unit to arrive.

"It's late," Cragen said, when he returned from the crime scene. "We have no leads. Everybody go home. We'll start fresh tomorrow. Hopefully we'll get something from the BOLO or CSU."

"Anybody up for a drink?" Elliot asked.

Surprisingly everyone decided to go out for a drink after work. Rarely did they all end up at the same bar at the same time. Munch usually went home, while Fin did his own thing. Occasionally Elliot and Olivia would go out for a drink. Elliot was surprised Olivia agreed to go out but pleased. He had hoped out of everyone she would say yes. He was still worried after her meltdown that morning.

The four detectives ordered dinner with their drinks. They took turns playing darts and shooting pool. One by one they headed out. Munch was the first to leave after playing a game of darts. Then Olivia headed out, quickly followed by Elliot leaving Fin in the bar chatting it up with a couple of narco detectives.

"Liv! Wait up!" Elliot called. He ran to catch up with her.

"I can walk El, the fresh air will do me some good," Olivia said, anticipating he was going to offer her a ride.

"It's not that," Elliot said. "Besides, I think I might have had a little too much to be driving."

"Uh-oh," Olivia said. "Do you want to crash at my place? Taxi fare to Queens is insane."

"Are you sure?" Elliot asked.

Olivia weaved her arm between Elliot's elbow and torso and the two of them started walking towards Olivia's apartment. They made small talk along the way. Elliot was impressed at Olivia's resilience. It was only 12 hours ago that she had been unable to function but now it was as if nothing had ever happened.

Olivia unlocked the door to her apartment and turned the lights on as they entered. She laid her stuff down on the counter and took Elliot's jacket and hung it up next to hers in the coat closet.

"I'm gonna get a quick shower, El, make yourself at home," Olivia told him.

Elliot flipped on the TV and stretched out on the couch. By the time Olivia finished her shower and headed back out to the living room she found Elliot leaned over on the couch with no shirt on. Her heart fluttered and a small smile appeared on her face as she took in the sight of her partner's bare chest. She never got tired of looking at him, especially with no shirt on.

Elliot sat up and made room on the couch for Olivia.

"Do you want me to put my shirt back on?" he asked her, unsure if she was uncomfortable or not.

"No, you're fine El," Olivia smiled at him.

Olivia tried to pay attention to show on TV but her eyes kept wandering over to Elliot's chest. She wished he would put his arm around her and hold her close to him but he seemed too involved in whatever sports program he was watching. She decided to be bold and moved closer to him on the couch, pretending to accidentally bump into him to try to get his attention.

"You ok?" he asked, smiling at her. She nodded her head yes and stared into his eyes longer than she should have before turning away.

"I'm kinda cold," Olivia said. Elliot grabbed the fleece blanket he had covered her up with earlier and spread it out over the top of them. He started flipping channels again; assuming Olivia didn't want to watch sports. He stopped on one of the late night talk shows.

It felt so natural to Olivia to be sitting next to Elliot on the couch watching TV. She was tired, and perhaps not thinking as clearly as usual. She curled up closer to Elliot and rested her head on his shoulder before she even realized what she was doing. As soon as her head landed on his shoulder reality hit her and was paralyzed with fear.

Elliot was surprised by his partner's brave move. He put his arm around her, thinking she just needed someone to comfort her. He gently squeezed her shoulder and the back of her neck.

Feeling Elliot's touch reassured Olivia. He hadn't pulled away or questioned her. She was able to breathe again. She reached her arm over, under the blanket and rested it on Elliot's muscular abs. What the hell am I doing she thought. Maybe it was the sleep deprivation or the alcohol she had consumed at the bar, she wasn't sure but she was touching Elliot in a way she had only ever imagined. She moved her hand up his abs to his chest and then the side of his neck before bringing it back down.

Elliot was taken aback by Olivia's advances. He wasn't sure if he was reading her correctly when she had rested her hand on his abs, but he was pretty sure he knew what she going for when she started caressing his chest and neck. He continued working at Olivia's upper back and neck with one hand and with the other hand took her hand and started inching it towards his waistline.

Olivia lifted her head up off of Elliot's chest and looked up towards him. He looked at her for a moment before leaning in slightly towards her. When she didn't back away he pressed his lips to hers. He then kissed her cheek and neck before returning to her lips. This time he opened his mouth, hoping she would do the same.

Olivia opened her mouth and let Elliot in. Their tongues met in a passionate kiss. She moved her hand over his dress pants and felt the growing bulge that was waiting for her. She felt Elliot buck his hips into her hand. She rolled her body on top of him so she was sitting on his lap, straddling him. She started grinding her hips into his as his hands explored under her shirt.

Elliot was pleased to find Olivia hadn't put a bra on after her shower. He rubbed his thumbs over both of her nipples while she sat grinding on him. He slowly pulled her shirt up over head, revealing her beautiful breasts and toned belly. He grabbed her hips firmly with both hands and held her still while he kissed her breasts. He knew if she kept going he wasn't going to last very long.

With Elliot holding her hips still, Olivia's hands quickly made their way between his legs and began rubbing at his length. She could hear him groaning in pleasure.

Elliot slipped his hand between Olivia's legs over her sweatpants. He could feel her trying to break free from his grip to move her hips against him.

"Come on," he whispered. He took her hand and led her back to the bedroom. They hardly got through the door before Olivia was reaching for the button on Elliot's pants.

Olivia had no trouble releasing the button or zipper on Elliot's pants. He stepped out of them after they dropped to the floor. Olivia was mesmerized by bulge hidden only by the thin cotton of his briefs. Elliot removed Olivia's pants and panties before stripping off his underwear.

Elliot laid Olivia down on the bed. He took a moment to take in the sight of her nude body before climbing on top of her. He moved his hips back and forth. He hadn't entered her yet but his penis was poking at her opening, making Olivia go crazy. She bucked her hips up towards him but he pulled back slightly, not wanting to enter her yet. He kissed his way up her shoulder, then her neck, until he reached her lips again. He held her hips against the bed while he continued teasing her.

"Elliot, please," Olivia whispered longingly into his ear.

"Please what?" Elliot asked before kissing her ear.

Olivia's eyes rolled back in her head with all the stimulation Elliot was providing. Poking at her entrance, his hot breath against her skin, then the light gentle kisses. Her senses were so overwhelmed she was unable to speak. She let out a deep, satisfied moan. Elliot captured her moan with another deep kiss. He let go of her hips and lined himself up with her entrance. Before he could enter her Olivia was thrusting her hips towards him.

"Slow down Liv," Elliot said into her ear. He pushed her hair back and kissed the exposed skin behind her ear as he pushed inside of her. He heard Olivia gasp as she took a sharp breath. He paused for a moment, giving her body time to adjust to his invasion.

Olivia was close to the edge before Elliot entered her. It didn't take long for his rhythmic movements to push her over the edge. She let out a long, deep moan as intense waves of pleasure over took her body.

Hearing Olivia's cries and feeling her writhing beneath him was all it took for Elliot. After a few final thrusts he joined Olivia in ecstasy.
