Okay, new fic...PLEASE don't kill me! The idea just popped into my head and I HAD to write it

I am still a die-hard Stella/Mac fan

Mac sighed; it had been another long day of nothing but paperwork. He glanced at his clock and chuckled when he saw that it was well past 2 am, meaning he should have been home close to four hours ago. He looked up and saw the staff of the night shift buzzing around the lab. He stood and closed the blinds of his office to work in privacy. He returned to his paperwork with a sigh, knowing he would be pulling a double shift with a few hours nap on his couch. A knock on the door startled him barely thirty minutes later. He looked up and smiled at the brunette standing there.

"Hey."

"Hi, I thought you might need this." She said walking in with a cup of coffee.

"Thanks." He replied taking a sip.

"You really never leave this place, do you?" she asked sitting down in the chair across him.

"You're one to talk, what are you doing here?"

"I was home alone, so I thought I would come in, get some work done." Jo sighed playing with her necklace. Mac nodded and smiled as Stella crossed his mind, thinking of the many times they had spent working in his office in the late hours of the nights.

"You're thinking about her, Stella I mean." Jo commented when she saw the look on his face.

"Yeah, things are just…different without her around." The brunette smiled sympathetically.

"I can imagine, she had been here for a while." Mac said. He stopped as Stella filled his mind. "Stop that." He commented when he saw the analytical look in Jo's eyes.

"Sorry. I'm going to get back to my work now, enjoy your coffee." She said. As she stood and walked to the door, Mac followed her.

"Jo." His voice stopped her as her hand reached for the door.

"Hm?" She said turning on her heel. Mac grasped her face in his hands, pulling it towards his and kissed her passionately.

"Mac, don't do this! You miss her, that's it." Jo said when they broke for air.

"I'm so lonely." He said before he pulled her in for another kiss. The time, Jo couldn't deny the attraction she felt for him; she had felt it since the first day they met. She moaned as he wrapped his arms around her and pulled her close.

"Are we allowed…" she began when they pulled apart.

"I don't care." Mac said pulling her into another kiss. He pulled off the red cardigan she was wearing and threw it to the side. Jo undid the buttons of his shirt and ran her hands up his strong chest, throwing the shirt to the ground. She chucked as Mac fumbled with her belt before pulling it off and throwing it to the floor. He looped his fingers in the pockets of her jeans and pulled her hips to his. Their lips met again, this time Mac played with the button of her jeans before pushing them down. Jo moaned as Mac lowered his lips to her neck, kissing the soft skin. She kicked off her jeans that had slid from her hips and down her legs, leaving her in her black panties. Mac pulled her white shirt off over her head and smiled as he looked at her bra clad breasts.

"Gorgeous." He breathed. Jo pulled him towards her again. Their lips met in a passionate, hungry kiss. She pulled his pants and boxers down, releasing his erect member from its confines. Jo sat down on Mac's couch and smiled at him as he moved her to lie on her back. He tugged on the black panties, pulling them down her long legs. Mac threw them to the floor next to his boxers and climbed over Jo, settling between her legs. Mac kissed her neck before moving down to her chest. All of a sudden, Mac glanced down and then back up at the woman beneath him.

"You have a tattoo!"

"Oh, God! Ignore that, I was young." Jo replied putting a hand over her hip.

"I like it, it's sexy." He said as he kissed her cleavage. He slid a hand down her flat stomach and between her legs. Jo moaned as two of his fingers slid into the wet heat between her legs. Mac kissed her neck as he thrust his fingers in and out of Jo, her moans egging him on.

"Oh God! Mac!" Jo moaned. He used his thumb to circle her clit. She arched against him as the waves of her climax began to hit her. Her nails dug into Mac's back as her walls closed in on his fingers. She moaned loudly as her warm juices covered Mac's fingers. He slid them out of her and licked them clean as she kissed his neck.

"Now Mac." Jo whispered in his ear. He positioned himself and, with a hard thrust, buried himself to the hilt in her warmth, listening to her cry out as her walls stretched to accommodate him.

"Are you alright?" he asked.

"It's been a while." She replied kissing his neck. After a few moments, Jo moved her hips, encouraging him to thrust. Within seconds, she was matching his rhythm.

"Oh, my God!" She gasped quietly. She hadn't been intimate with a man in a long time; her work had kept her occupied. Mac lowered his lips to her chest. He gently tugged at her bra with his teeth, pulling it low enough to free her nipple. She arched against him again as he gently bit the hardened bud. He knew every little thing he could do to heighten her pleasure and he did them to perfection. Mac slid a hand to her back and quickly undid the bra clasps, pulling it off. She moaned loudly again as he scraped his teeth over her nipple before flicking it with his tongue. She wrapped her legs around his waist, opening herself to him. Mac groaned against her skin as he slid deeper into her.

"Mac," she gasped. She didn't have to say more than that; he knew what she meant. He slid a hand between them and teased her clit with his fingers. Jo arched against him for a third time, pressing her hot body against his. He felt her legs tremble against his sides, her breathing shortened and her fingers squeezed his biceps. Seconds later, she cried out his name as her orgasm shook her, her body's warm nectar showering Mac's cock. He grunted her name as he came into her. Mac lowered himself over Jo, listening to her accelerated breathing.

"You were amazing." She whispered into Mac's ear, pressing her cheek against his.

"You too." He replied before kissing her neck. When their breathing had return to normal, Mac got off the couch and grabbed his clothes. He put on his pants and then glanced at Jo, who had slid into her clothes again. She lay back down on the couch and closed her eyes.

"I really do love this tattoo." Mac said kneeling beside her and pulling down the side of her pants and underwear to place a small kiss on the purple butterfly tattoo. Jo sat up and looked at him with a playful look in her eyes.

"I have another one. Meet me for dinner tomorrow, my place at eight and you might get to see it." She winked as she slid off the couch and walked out the door. Mac sat on the floor surprised. A smile crossed his lips as he imagined where Jo's second tattoo could possibly be…he was determined to find out.

Please review if you liked...might be a chapter two in the works as well :)
