It had been a very long day and Mac still had a ton of paperwork that he needed to finish before leaving. It was already late and he was getting sleepy. He was reading through some papers, getting sleepier and decided he would get another cup of coffee. Just as he was about to get up he heard a soft knock on his office door. He looked up to find Jo standing there. "I thought you left already" he said.

She shook her head. "No, I was actually waiting for the team to leave."

"Why?"

"I needed to talk to you," she said, hesitantly.

Mac looked at her curiously. "Is something wrong?"

"I can't stop thinking about you Mac. I've fallen in love with you and I can't take my mind off of you."

Mac looked at Jo, surprised and unsure of what to say. He couldn't stop thinking about her either, but he's her boss, so he never thought it would be appropriate to make a move on her. Appropriate or not though, he wasn't going to let this opportunity pass. He wanted her so bad he couldn't be around her much anymore without getting an erection. He was hard already just from thinking about her.

He stood and walked over to her. He looked into her eyes for a moment, then took her things from her hands and set them down. He pulled her close and kissed her deeply. She returned his kiss and ran her hands over his strong chest. They continued kissing until they had to stop for air. Mac closed his office door and pulled her over to the couch. He sat down and she straddled him and continued kissing him.

Mac slowly slipped his hands under Jo's shirt and cupped her breasts. Jo gasped and began to rock her hips slowly, rubbing herself against him.

Mac gasped, "I need you Jo." He moved his hands around to her ass and pressed her against him. "Do you feel that?" he asked. "That's what you do to me."

"I want you Mac," Jo moaned.

Mac unbuttoned her pants and slipped his hand into them and into her panties. She gasped. He slid one of his fingers inside of her and then added a second. He couldn't believe how tight and wet she was. He fingered her for a few minutes until her moaning and squirming was more than he could take. He needed her now. He removed his hand from her pants and motioned for her to take off her clothes. He unbuttoned his pants, which had become unbearably tight, then pushed them down along with his boxers. As he finished undressing he watched her and thought she was the most beautiful thing he had ever seen. She finished undressing and looked down at his cock and licked her lips. He was surprised he didn't cum right then, just from the way she was looking at him. She straddled his lap and began kissing him again. He ran his hands over her body and back between her legs, rubbing his fingers softly over her swollen, sensitive clit.

She gasped, "Now, Mac."

He moved his hand and placed himself at her entrance, put his hands on her hips and guided her down onto him until he was buried to the hilt. She could feel him stretching her and it felt so good she couldn't stop herself from moaning louder. Mac watched her face as he continued to move deeper into her. She was beautiful. Her eyes were closed and she had a look of pure ecstasy on her face. He was falling for her harder than he would admit, even to himself.

Jo stayed still for a moment to adjust to his size, and then started rocking on him. He moved his hands over her soft body, caressing her as she rode him. He kissed her neck and squeezed her ass. She moaned and moved faster on him. He groaned and dug his fingers into her hips and brought her down hard onto him. She lost control and rode him faster and harder until she came, crying out his name. The feeling of her walls clamping down on him drove him crazy. He picked her up and flipped their positions so that she was on the couch and he was in front of her with his knees on the floor. As he moved in her he sucked and nibbled her breasts, giving each equal attention. He slowly kissed his way up her neck and then kissed her passionately. He pulled back from the kiss and placed her legs over his shoulder and looked into her eyes for a moment before he began driving into her hard and fast. She screamed out his name as another orgasm overtook her. This time she took Mac with her and he moaned out her name as he spilled inside of her. He put her legs down and they held onto each other panting for what seemed like hours.

Mac was suddenly startled awake when Lindsay walked into his office to give him some lab results relating to a case she was working on. He looked at her, confused.

"Mac, are you okay?" she asked. She had found him sleeping with his head on his desk when she walked in.

"Yeah, I was just ….. What do you need?" he replied.

"I just wanted to give you this." She handed him the file then left his office.

When had he gone to sleep against his desk? The last thing he remembered was holding Jo.

He sighed and put his hand over his face. Another dream, he thought, frustrated. He really needed to get control of himself or finally tell Jo how he feels.

He went to the locker room and took a very cold shower, then put on his extra clothes that he kept at the office and went about his day.
