Riley let out a quick moan as she felt her body be slammed against the now shut apartment door. Hands reached behind her and grabbed her behind, pulling her up and draping her legs around his waist. Riley leaned her head back as she felt lips begin to attack the sensitive skin of her neck and shoulder juncture. "You know how wrong this is." She let out sharply, reaching out to thread her tiny fingers into the head of dark blonde hair in front of her.

She felt a vibration as a laugh escaped the lips that were still pressed hungrily to her skin. Now that her legs were secure enough around hips, he moved his hands from her behind and moved them up the back of Riley's shirt, causing a shiver to come out of her due to his cold hands against her warm skin. "But do you think I care?" he retorted, replacing his hands where they belonged and proceeded to carry Riley to his small bedroom, their lips now connected as he stumbled over dirty clothes and just junk that hadn't been straightened around and instead strewn across the room.

He tossed Riley gently onto his bed and smirked as he watched her slowly crawl up to the top and lean against his headboard sensually. Riley crossed her arms and wrapped her fingers around the hem of her tight navy blue top and she lifted it up over her head, throwing it somewhere off of the bed, but he really wasn't worried about where her clothes went. He just didn't want them on her at the moment. "Greg?" she questioned, a mixed look of confusion and arousal on her face.

Greg tossed his shirt off and threw it into a corner, raising an eyebrow as he too climbed onto the bed and crawled up to Riley, his face hovering over hers as his hand tangled in her long blonde locks, the scrunchie holding them back long gone. "Hmm?" he answered, kissing the corner of her mouth softly.

"Do you?" she asked, moving her arms around his neck, laying herself down on the bed and pulling Greg's body down with her, his hands now on either side of her head. He smirked and lowered his mouth to her ear.

"Right now, all I care about is being with you." He whispered, saying the only thing he could've thought of at the moment. He pulled his face away from her to come face to face with her, not knowing how she would respond to what he said. Greg found himself very fond of her reaction as Riley reached a hand behind his head and brought his lips to hers eagerly.

Sure, the few beers they had after shift may have had something to do with the current animalistic events that were taking place in Greg's bedroom, but the two CSI's attraction to one another was the small campfire, unpredictable to whether it was going to stay lit, go out or become bigger and the alcohol had just been a bit of an accelerant for the events.

Soon, clothes from the two co-workers had been abandoned on the floor and nothing was in between the two besides the thin coat of sweat that neither knew if it was theirs or the other's, nor cared. Riley threw her head back as she felt her body be invaded passionately. She let out a sweet moan of approval as she adjusted to his size and began to move her hips upward, meeting Greg's.

Greg grunted in agreement, his hands meeting hers and entwining each other on both sides of her head. He leaned down and pressed his lips to her neck, careful not to leave any visible marks. Well, at least visible to anyone who would walk by. Anything hidden by clothes was fair game according to Greg. He lowered his lips even more, resting right above Riley's breast and proceeded to make a red mark that would be seen by her for quite a while. All the while, he kept pushing into her, gaining speed as Riley's cries began to get louder.

She smiled and caught Greg off guard while he was tending to her skin. She was able to untangle their hands, grip his biceps and flip their positions, with Riley now on top. Greg just gave a quick 'Damn' to Riley's cat-like reflexes and how quick she was able to flip them. Riley grinned down on the former lab rat and laughed as his hands grasped her hips and began moving her back and forth as she straddled him. Riley gave out a strangled moan as she moved in time with Greg's hips going upwards into her.

"Greg." She bit her lip and closed her eyes, determined to hold on longer than what she had been. She felt Greg's move from her hips, up to her breasts and she felt him take one in each of his hands. She could feel her eyes begin to roll back into her head as she moved faster back and forth on him.

Greg swallowed deeply, his mouth becoming dry from gulping down air as he let out groans. "Come on, baby." He said, flipping them back around for what would be the final time. Greg grabbed a hand out and pushed on her lower back, making her arch up into him. They matched each other movements, the bed creaking in reply to their lovemaking. It wasn't long before the two were laying side by side, panting loudly.

Riley moved closer to Greg, her head on his shoulder and a leg draped across his hip. She looked up at him. She smiled when she saw him looking back down at her. He reached under them, grabbing the edge of the one lucky sheet that hadn't managed to fall off the bed and he covered both of their bodies with it. "Well, I was wrong." She said, aimlessly running her index finger over Greg's chest and stomach.

Greg stopped his fingers running up and down Riley's back as he looked down at her and raised an eyebrow. "Wrong about what?" he asked, slightly confused on what she was talking about. Riley shrugged and clarified.

"I always thought you liked to pull hair." She smirked as Greg rolled his eyes and continued his fingers' movement on Riley's skin. A few moments had passed until he opened his mouth to say something and when he happened to glance down, he closed his mouth with a smile, seeing Riley soundly sleeping on him. He leaned down and kissed her head, closing his eyes hoping to join her in slumber.
