The watcher

Reginald "Reggie" Mc Neil had always thought of himself as the quintessential ladies' man. He was good looking, smooth, and macho. The women in his hometown had fallen over themselves to get into his bed. He'd been the football hero, and now he was an ex-military man.

He was six foot five and two ten. He had black hair and dark brown eyes. Every woman he knew loved his eyes and his muscular build. That is, every woman but her. He couldn't understand Agent Jareau. He worked the night shift in the lobby and saw her every night. He said hello. She said hello, but she never flirted or even looked his way. It didn't make sense.

Now… there was a bigger problem. She'd started looking at that nerd, Supervisory Special Agent Dr. Spencer Reid, like he was chocolate and she was starving. What was so great about the wimp? He wore glasses for God's sake. He wore clothes that only assistant professors and prep school boys wore. He was so skinny… Reggie bet he could snap the agent in half with no effort at all. And that hair, what was up with the Crispin Glover look?

No… It didn't make sense at all. Now he was watching the camera in her office. He was supposed to be keeping an eye on the lobby, elevators, and the parking garage, but he couldn't resist watching her. The problem was that the geek was in her office again. That God damn little pup… They were sitting there and she was working while he watched her. Didn't he have a home to go to?

Wait… it looked like things weren't so great. Well… maybe there was trouble in paradise. That would be great.

He watched the monitor intently, ignoring an agent that came in and said hello as he passed by the desk. The agents couldn't see the screen, and there was no sound, so Reggie didn't worry about anyone seeing what he was up too.

It was getting late and the building had emptied out pretty fast. He noticed that Agent Hotchner had left. He tried never to speak to Agent Hotchner. That man had scary eyes that seemed to know everything.

Well… Things just got interesting. Reggie dropped the meatball sub he'd been eating and leaned forward for a closer look. Agent Jareau had the nerd up against the door and was trying to stick her tongue all the way down his throat.

Reggie felt his hands curling into fists. This was completely crazy. She couldn't possibly be that attracted to the pipe cleaner.

Now they'd stopped, after Agent Jareau had grabbed his dick. He looked like he was about to pop right there and then. Reggie began to snort laughter. Most likely the skinny guy was a god-damn virgin. That was a great turn of events. She'd realize that the geek couldn't hold back long enough to get her off and she'd turn him loose. And he was going to witness that humiliation first hand. Too damn bad he couldn't steal the recording for his own pleasure later.

Then the scene changed and he was leaning forward again with clenched fists. It looked like the clothes were coming off and now they were on the floor. He couldn't see anything of Agent Jareau, but her bare back. He could see Dr. Reid and his face which looked like Christmas had come early.

Speaking of 'coming early,' maybe that could still happen and… Wait… they looked like they were arguing again. God he wished he could see her face. She was the one he wanted to look at, not the nerd!

The rest of their clothes came off after she pushed him over on his back. He'd looked surprised for a moment. He was talking to her again and after a minute Agent Jareau bent over to kiss the nerd. God… It made him sick to watch it. He looked at her bare backside and felt himself stiffen. She had a marvelous body, and once again he cursed out loud that he couldn't see her from the front. It looked like the nerd liked breasts because his hands were busy with her chest.

--

JJ had straddled him and was grinning down at his face that had gone very red. "JJ…"

She ran her hands slowly down his bare chest as he shifted beneath her. She was pressed against his rigid cock and she was so wet and warm.

"Tell me what you want."

"I…" He swallowed and his hands reached up for her breasts. "I want you. Please JJ… Make me warm."

Her hands continued to slide up and down his chest to his abdomen. He was beginning to shake, just like he always did when very aroused.

"Your wish is my command." She whispered before placing a kiss on his chest.

"Oh God… JJ…" She engulfed him to the hilt and his hips rose up to meet her.

"I love you Spence." She said breathlessly before beginning to move slowly back and forth.

--

It was intolerable watching that skinny little prick getting what should be his. It looked like Agent Jareau, or what he could see from the back was enjoying it too. Who would have thought to look at the little bastard, that he could pleasure a woman?

Well one thing was true… Reggie didn't let any woman on top. The women he slept with spread their legs for him. They took what he had to give and thanked him for it. Agent Jareau would do the same and he knew just how to do it.

He watched the tape and saw Agent Jareau throw her head back. She looked like a fat cat that had just had a bowl of excellent cream. The nerd was bucking up against her and Reggie growled again in his chest. He could imagine the wet, hot, feel of Agent Jareau and how it could make a man crazy with lust.

Her hair was like spun gold and one day soon he was going to plunge his hands into it at the same time he was taking her. She would scream for him. He knew it. God… he was turned on… It was hell to watch. He wanted to kill that geek with his bare hands.

It was finally over… He could tell from the movement and the way the nerd's eyes rolled back in his head. The bitch was lying on his chest and they were talking. That was something else Reggie didn't do. He didn't talk, or cuddle afterwards. What was there to talk about? He never said he loved any of them. He bet the nerd was telling her he loved her. What good did that do, but give women ideas.

He shut off the camera, returning it to the original setting. He wasn't supposed to leave his post while on duty, but he had a raging hard on to take care of. He went into the bathroom entered the first stall and slammed the door. He was going to think about that uppity agent while he spanked it and soon she'd be his.

--

"Spence… Oh… God…"

His hands were on her waist, his long fingers curled into her flesh, and the pain of the grip was a strange counterpoint to the building pleasure in her abdomen.

"JJ…" He said her name over, and over again.

"Spence… I… oh god so close… baby…"

One long fingered hand left her hips and slid between them. He found her swollen and sensitive numb and began to stroke it firmly.

She threw her head back and tightened around him. "Yes… oh god… Yes!"

The feel of her inner muscles clamping down on his, pushed him past the threshold of control and he emptied himself deep inside of her with a loud cry.

She slid down to lay over his heaving chest. Getting her breath back took several minutes. His arm held her tightly to his body and he was kissing her sweaty forehead.

"That was amazing…" He breathed.

"In spite of the hard floor," She asked.

"Don't care about that…" He wheezed, hugging her tighter.

"I want to tell you something Spence."

"What…" He nuzzled her neck.

"I love you so much."

"I know that…" He said softly stroking her back in an up and down motion that was hypnotic.

"I just wanted you to know that I'm never going anywhere."

"I know that JJ…"

"Whatever happens to us, I'll always love you."

"I know…"

She rolled off him and began to get dressed. "That was fun, but I think we should find something softer than the floor." She said.

"Okay…"

She slapped his bare shoulder when he sat up. "You don't have to sound so eager. I never realized how much of a sex maniac you are. You look so innocent."

He waggled his eyebrows at her and she laughed. "Come on, get dressed Romeo!"

--

When Reggie turned on the camera in JJ's office it was empty. Well… it looked like the cuddling was over. His face began to burn with anger at the thought of the nerd going home with her. It just wasn't right. It was against the natural order. The pipe cleaner should be with some nerd bitch, not with the most beautiful agent in the bureau.

He sat back, and finished the hero sandwich he'd put aside. It didn't matter. She'd be his soon enough!

A/n yeah the camera angles are a little wierd I know, but I claim authors creative license for the whole story!
