Summary: Penelope has an addiction. What her teammates don't know is that more than one of them is involved in it. Will they be able to help her before it gets out of control?

I've had this sitting on my desktop for the last few months debating about whether I should post it or not. Please let me know what you think and if I should post the rest of it or not.

…

He felt a tightening in his slacks as he stepped into the bedroom and his eyes fell upon her, lying naked on his bed wearing nothing but a coy smile.

"I've been waiting for you," she purred, spreading her legs and running her fingers over her dripping mound for his viewing pleasure.

He knew what he was doing was wrong. Aaron would kill him if he ever found out that he was sleeping with a colleague but Dave just couldn't help himself.

Besides it had been Penelope who had come to him, not the other way around. He knew that didn't make it right but what was he supposed to do when Penelope showed up on his doorstep after a bad case, practically begging him to fuck her?

As it was, after spending more than a few nights with the luscious blonde, he was already screwed if anyone found out about them, whether he stopped seeing her or not.

She moaned loudly as their eyes connected, her fingers slamming enthusiastically into her pussy as she waited for him. He crossed the room with long strides and came up beside the bed. Penelope grinned at him, pulling her hand away. She pushed herself to her knees and crawled over to him "What took you so long? I though you said you'd be right up?"

Dave sighed "I got a call from Aaron."

Penelope pouted "The Boss Man doesn't want us to come in, does he?" she asked, already pulling off his belt.

Dave held back a groan as Penelope's hand pulled down his fly and cupped his cock through his pants "No…" he muttered, "he called to let me know that he's having a barbeque at his house on Sunday…he wanted to know if I could make it. I'm sure you'll be receiving a similar call from him sometime soon."

"Can you?" her hands pushed down his pants and boxers as she asked.

"Yesss…" he hissed as Penelope grabbed his cock and squeezed.

She nodded before leading him, cock first onto the bed. He managed to kick off his pants as he followed.

Penelope stroked and squeezed him, her hand running up and down his manhood with vigor while Dave unbuttoned his shirt and threw it away.

Once he was naked, Dave leaned down and pressed his face into Penelope's large breasts. She moaned her hand still between them on his shaft as he used his mouth to encircle one of her nipples.

"Uhhh Dave," she groaned, squeezing him a bit too hard. He hissed at the feeling but didn't say anything, a little bit of pain mixed with pleasure wasn't a bad thing. "I've been waiting for this all week."

In response Dave sucked at her nipple harder and Penelope squealed, her free hand fisting into his hair and pulling his head closer. Dave grinned against her breast and grazed it with his teeth. Panting Penelope arched into him, giving him another painful squeeze.

She moaned in loss when he pulled away from her and gazed down at her body. His legs straddled her waist while his hands moved to cup her large breasts, flicking his thumbs over her hardened nipples as he did so. "God, you're beautiful Penelope," he groaned as his hands slipped down farther, exploring the curve of her waist and splaying over her navel.

Penelope bit her lip, she released his cock and was staring up at him with anticipation. Dave let his fingers drift down ever so slightly, letting them graze against her mound. She took in a sharp breath as his fingers continued down.

"Dave…" she hissed, pushing against his hand.

"Ah Bella, none of that," he murmured before pressing her hips down and lowering himself to her pleasure. His tongue flicked out as he tasted her causing Penelope to whimper.

"Please," she urged, she needed him badly.

Dave smirked, his fingers parting her lips before he allowed his tongue to explore her. He nipped at her bud trying to get a response. He wasn't disappointed; her fingers scraped the skin on his shoulders as she called out.

Not missing a beat he continued his exploration, driving his tongue into her and using his fingers to pinch her clit.

Finally Penelope couldn't take it anymore, she growled and pushed Dave away "David," she said when he looked at her in confusion "I need you, now!"

Dave grinned; he moved up her body and positioned himself against her opening.

His eyes met hers and she shoved her hips forward, using her body to tell him to get on with it.

He chuckled before shoving into her, she gasped with pleasure at the intrusion. He studied her face, enjoying the look of pure pleasure that was etched across her face. He pulled out so that only the tip was still penetrating her, then he sent her a little smirk before shoving back in.

She whimpered as she automatically wrapped her legs around his hips. He began a slow constant pace as Penelope's nails scraped against his back. Every stroke was hard and precise, with every one he was gifted with a moan from Penelope.

"Dave, uh please," she moaned deeply after a few minutes "need more, faster."

Dave picked up his pace and began slamming into her, making the bed shake underneath them. By then she was crying out with pleasure. Both her legs and her arms wrapped around him, pulling him against her hard. He could tell that she was close and used one of his hands to slide down in-between them. His fingers found her clit and squeezed causing her to scream and bite down on his shoulder.

He groaned at the feeling of her walls constricting against him as she came. He continued to pump into her breathlessly now.

He was so close it almost hurt. He slammed into her hard as she continued to moan under him. With one last thrust, his body stiffened above her and he came with a shout. His orgasm pulsed out of him as he shot his load inside of her.

He took a few deep breaths before rolling off of her, and lying on his back beside her. He listened to her deep breathing, hoping that for once she would stay with him but just as he was starting to think this time might be different, he felt movement beside him.

He turned to look at her "Penelope?" he began.

She turned back to him, a small forced smile on her lips "I've got to go," she mumbled to him, all of the confidence she had just exhibited, leaving her, which always seemed to be the case after these encounters.

"Are you sure?" Dave asked, speaking out for once "you know, I'd be happy if you stayed."

A guilty look that Dave didn't understand crossed her face "Sorry Dave, I really have to go." Then she was on her feet gathering up her clothes and slowly dressing, when she turned back to him the guilty look was gone.

"I'm sure I'll see you at the barbeque Sunday if we don't get a case," she said with a small smile.

He started to get off the bed and go to her but she quickly moved to the door "Don't worry, I can show myself out. Good Night."

"Night…" Dave said as he watched her leave, he sighed in frustration.
