(A/N: I'm not sure if I like it when I have an idea of how a Chapter should go, and suddenly it takes on new and more involved story twist as I'm writing it. This Chapter came out longer than I planned also. Thank you for all the reviews. I hope you all enjoy this Chapter. KK)

The Wonder Weekend (and that's how Penelope was beginning to think of it) was over and Monday morning had arrived. Now that they were back from their haven at the cabin, she was beginning to doubt that everything had really happened. Dave had dropped her off at the elevator from his SUV and then went to park, wanting her to be sure of her safety.

In her own world, she stepped into the elevator. Hearing a voice call out, she stopped the doors from closing and moved to the side as Reid stepped in.

"Morning, my duckling."

"Hi, Penelope. I tried calling you this weekend and when you didn't answer, I got worried. You always answer your cell." Spencer didn't see her worried look as he finished adjusting his bag. "I called the doorman to check on you."

"You did? What eased your mind?" Penelope watched Reid intently.

"Oh, I called and he said you and Rossi had left together." Finally getting his bag adjusted the way he wanted it, he looked up at Penelope. "Did you have car trouble or something?"

"Dave gave me a ride and I'm fine, ducky, don't you think another thing about it." Walking to the break room to put up the pesto Dave had sent with her for her lunch, she hoped Reid wouldn't notice the slight quiver that she hadn't completely managed to keep from her voice.

Leaving the break room, she saw Dave and Spencer talking outside the elevator. Making a quick decision she took a sharp right and went up the right side of the pen, making a beeline for her office door. Turning, Dave followed her with his eyes before taking leave of Reid and following her.

Dave blinked at the door that had just been closed in his face. Knocking of the door to Penelope's office, he heard her voice from the other side.

"What?"

"Penelope, what's wrong?" Dave leaned against the doorframe, curious to see what her answer would be.

"Nothing's wrong! I have work to do." Hearing her chair squeak as she got up and her voice get a little louder as she moved towards the door "Go away!"

"Kitten, I'm not leaving."

"Well, have a pleasant day while you stand there then."

"Let's talk, Kitten." Rossi found himself befuddled a bit by his Kitten's attitude.

"I really don't feel like talking right now. Come back later. We'll talk later."

He shook his head silently. If he knew one thing about women, he knew that, if he left now, they would never have this conversation. And, he felt that this might be one of the important ones. "Cara, if I leave now, you'll pretend that this never happened."

"You know, Super Agent, I like that plan."

"Would you stop being so stubborn?" He sighed as he settled a little more against the door. This was going to take some serious wiles he was sensing on his part.

"Like that's going to happen" was muttered rebelliously from the other side of the door.

"Well, dolce, I'm not changing either."

"What's that supposed to mean?" issued rather stridently from behind the door and reached his ears. He grinned.

"I'm not leaving here, Penelope, till we talk." Dave decided to go with a little pleading. "Please, open the door and let me in. Please, Kitten?" He stumbled a little as the door cracked open.

Penelope peeped out at him from behind the door, "Are you going to use your negotiator super powers on me?"

A small quirk to his lips, Dave asked her, "You opened the door just so I'd leave, didn't you?"

"Maybe. So, you see me, I'm fine, now go away." Penelope put her hand back on the doorknob.

"What has you so nervous?" Reaching out, he cupped his hand around her hand, taking if from the door knob and bringing it too his lips, placing a small kiss upon her fingers before lowering it to hold it in both of his and rubbing his thumb back and forth over her knuckles soothingly.

"What has me nervous? I'm fixing to spend my day around awesome profilers that will probably be able to take one look at me and tell I've been good and laid!" Letting the door open a little farther, she flipped her other hand out over Dave's shoulder at the empty area of the pen behind Dave, muttering almost to herself, "There is no privacy with profilers."

"Kitten, while I'm glad to know the weekend was good, why are you so worried about this? Do you think we did something bad?" Lifting a hand, he caressed her cheek.

"Well, to paraphrase Mae West, "When I'm good, I'm very very good. But, when I'm bad, I'm better.'" Penelope leaned her head into Dave's hand. Hearing the elevator ding of another incoming early arrival, she quickly pulled Dave inside. Dave leaned back against the door jam, looking at his sexy Kitten.

"I do not think we did anything bad, Dave. But, that does not solve the problem of super profiling skills that will be gathering in the room out yonder soon! How am I supposed to act around all of them? Around you?! How am I supposed to be around you and not think about how you-"

Pulling her into a kiss to hush her anxious babble, "Penelope, listen to me." With sincere feeling, he asked "Were we friends before this weekend?"

"Yes." Penelope looked up into his eyes, some of her apprehension fading.

"Are we still friends now?"

"Yes." This answer was given a little more firmly.

"No matter what happens in here or out there; I am, and always will be, your friend. I admired you before we had this weekend." With a delighted grin, Dave continued, "I anticipate watching you be yourself no matter where you are with lustful enjoyment. There isn't anything that can happen that is going to change that."

"Reid knows Dave! He caught me in the elevator on the way in. He called me last night to see if I could come over but couldn't reach me. When I didn't answer my cell, he called back to the BAU and the guard mentioned that he had seen us leave together. Reid probably won't think anything of it. But the rest of the team, Dave - What if they find out? What if they all know?"

David paused. Was she ashamed of being with him? With a touch of uncertainty now coloring his voice, Dave asked, "Penelope, do you not want to see me again? Personally? Because, if not, I need to know now-"

"No! I mean- Yes, I want to see you again!" Thinking about how everything up to now had sounded, Penelope frantically tried to make sure Dave lost that air of hesitancy. "Mon Loup, I look forward to the time we can spend together again. Just thinking that we have plans for Tuesday evening gives me something super spectacular to look forward to."

"Then, what is it?" Coming back to his first question, Dave asked it relentlessly.

"I – well, I don't know if I'm ready for the inquisition. JJ and Emily are going to want to know everything. And Derek! Good Lord, my honey bunny doesn't even know I was thinking about starting dating again.

How am I going to explain to him?" Going back to her rambling concerns, "And, oooooh, how do I react if you've been with any of them?" Looking up at Dave from the circle of his arms, she asked tentatively "Have you and any of the team – you know?"

Hearing the insinuation in her voice, Dave smiled again with ironic humor, "I have never 'you know'-ed with anyone on the team." Being fully honest, he added, "Me and Erin Strauss had a thing one night a long time back. But, I've only every kissed one member of the team. And it was just the one team member. And kissing was all that happened." Thinking about their conversation this weekend before things had gotten interesting, he decided to add, "Maybe we should have had a discussion about relationship history before coming into work. Especially about you and your 'honey bunny'?" Dave looked down seriously to Penelope. "You told me you and Derek had missed your chance when I asked –" He let his voice trail off in a question.

"Okay, former FBI Lothario, let me be explicit." The thought crossed her mind rapidly that maybe they should have talked a little more this past weekend. Remembering the steamy weekend, she shook her head mentally, nah, she wouldn't have changed anything about this weekend, best to have this conversation now than give up any moment of this past weekend. "I've only done the nasty with one member of the team. And it wasn't Derek. Nope. Nada. Never happened. Me and Derek have only snuggled or hugged, ever. The only sleeping together we've ever done is sleep."

With a quick grimace, and thinking of how friendly he was with his coworker, Dave asked "Please tell me it wasn't Hotch?"

"Listen you, I'll tell you mine at the same time you tell me yours, Casanova." This came out with a little more of a challenge than she intended.

"Agreed." Dave looked down at her. No secrets. At least, he didn't want any between them. "On the count of three?"

"Ok." Penelope nodded.

"Together then. One, two, three-"

Speaking at the same time, they both said, "Emily." "Emily."

"Emily?!" "Emily?!" One female and one male voice both sounded inside the small enclosed office, both ringing with a little disbelief.

Dave paused as the riveting image of Emily kissing his Kitten flew before his mind's eye; the feel of Penelope whopping him across the chest shook him out of it swiftly enough.

"I can't believe you kissed Emily!" Penelope sounded shocked, before she let out a little giggle. "How did it happen?"

"Kitten, we will have to trade stories later." With a wiggle of his eyebrows, he added, "Stories that need to be told in detail I believe." Smiling as she giggled again, "I can hear people moving outside." He moved down to place a kiss on her lips but she dodged him.

"You can't kiss me, you'll end up with lipstick all over and unable to get it off. " She rested her head against his chest, "How am I supposed to act, Dave?" Penelope relaxed in his arms, but still sounded confused.

"Like we're friends, Penelope. There is nothing different but one thing." Dave found himself interrupted by Penelope.

"One thing! One thing? Yeah, one thing - but it's kind of a big thing, mon loup!"

"Penelope! While I thank you for the implication-" Dave laughed as Penelope cut short his sentence.

"You ass! That wasn't what I meant," taking a swing at him, she wiggled against him, trying to free herself as Dave held her closer.

Grabbing her hands, one in each of his, he pulled her back towards him. "The only thing that has changed is that you have found out something you did not know before." Dave looked down into Penelope's wide eyes, framed charmingly by her unique glasses.

"What, Agent Ass, that you've got a big –"

Dave refused to laugh. Now, he was serious. He wanted Penelope to know how serious he was, and for some reason, he didn't think flowery words would convince her. Deciding to go with earthy and straight forward honesty, Dave said, "No, what I'm talking about is something real. You've only found out that this –" placing one of her hands on his crotch, " – and this –" he placed her other hand over his heart – "is yours." Holding her hands against him, not bothering to hide how he was hardening beneath her touch, or that his heart had sped up its beat at having her hands on him, "They are only yours. I don't stray, Kitten."

Penelope stared up at David. The smile slowly left her face and she could feel a fire burning inside her. One that was burning away her nervousness. He was so intense in his honesty. Stroking her hand against his chest, she felt his hand tighten around hers as she also extended a caress with her other hand, the one that now felt his hard length beneath her fingertips.

Dave watched with hot eyes. Her hand, light as she was with her touch, felt like electricity flicking over him. Her nails and fingertips outlining his hardness beneath his slacks.

"Mine, David Rossi?" She asked clenching her hand in his shirt, over his heart. She looked up at him when she asked her question.

"Everything, Penelope. " He answered in the affirmative, attesting to the reality their relationship.

"Mine then, David Rossi. Mine." Penelope felt her worries slip away.

David watched as her fingers stroked him slowly. Clasping him and then releasing. His breathing got heavy and he pressed his forehead against his Kitten's, watching her eyes as she touched him. He cradled Penelope in his arms, drawing her closer as her grip strengthened, a ragged groan escaping his lips.

Knock. Knock. Knock.

"Penelope? Penny-kins?" Kevin Lynch's voice rose from the other side of the door.

"I'm busy." Penelope didn't stop her movements, loving the feel of David against her. Harder, deeper breaths stirred her hair as David leaned more towards her.

"I'm sorry about not telling you I was seeing someone else. "

David opened his mouth to shout at the ninny babbling beyond the door to leave when Penelope placed the fingers of her right hand across his lips and grinned, "I really can't talk right now. Agent Rossi just put something in my hands that I need to work on." Her left hand reached up and unfastened the belt of his slack. David opened his mouth and closed his lips around her two fingers, sucking on them slightly. Penelope felt feverish. Her fingers were surrounded by wet warmth and her left hand drifted inside Dave's slacks, finding heat of a different sort greeting her.

"Penny-kins" Kevin almost whined as he leaned closer to the door.

"Go away Kevin!" She pulled her fingers from Dave's mouth and looked down as she pushed open Dave's slacks. Licking her lips, she freed his length. Holding him with one hand and sliding the other one down to fondle him, she thrilled to the change in Dave's breathing as it grew harsher and rougher.

"It's just, I'm sorry, Penelope. Don't hold a grudge, okay?" they barely acknowledged the sounds as Kevin moved away from the door, both focused on what Penelope was doing.

Gruffly Dave ordered her, "Tighter, Dolce. Please." Pleading in his husky voice, "Faster."

She wrapped one hand firmly around, moving up and down his length, quickening her pace as she fondled him with her other hand below where he throbbed at the touch of her hand. Dave stifled his moans as Penelope stroked him, his eyes not leaving the sight of her white hand on him, her nails glinting happily with her spectacular color choice. He wanted this memory to savor later, something special that happened here, in his workplace. Something he would always remember. Suddenly she added a slight twist of her wrist at the end of each stroke and Dave felt his toes curl in his designer shoes as his hips involuntarily bucked towards his Sweet Goddess.

Knock. Knock.

"Hey, Mamacita, are you going to hide in there today?" Derek's voice came jauntingly through the thin wood of the door.

Not stilling her movements, she continued to stroke him, enjoying watching the dark skin flush with passion, seeing his muscles tighten with each caressing squeeze.

"Hello, my Chocolate Knight, I would love to say 'no' but I'm working on something for SSA Rossi. He just told me to tighten up and finish faster so I'm not stopping right now. " She smiled wickedly up at Dave as she licked her lips. He let out a low growl, trying not to be too loud with his low grunts, each one emphasizing the jerk of his hips as they arched towards Penelope and the beguiling dance she was leading him in.

"Come on Mama, open the door. Let me see that smiling face." Derek tried persuasion, hoping to coax her out.

"No, my Sweetness, I just need to do this right and it won't take long at all."

"Okay, Little Mama." Derek wandered away. Finding Reid at his desk, he sat on the corner of it and stared back towards Penelope's office. Looking at Reid, "Did we pull a case?"

Not looking up from the computer screen, Reid replied, "Not that I know of. Why?"

Derek swung his hand back towards the way he had just come from, "I heard Kevin bothering Penelope and went to intervene. Penelope told Kevin she's working on something for Rossi. I thought she was just saying that to get rid of Kevin but she wouldn't let me in her office either." Looking down at Reid when he heard a muffled snort, "What are you smiling at?"

Reid continued working on the paragraph he was looking at on his computer, not wanting Derek to see the look in his eyes or let his body language give him away. It wasn't often that he 'got' something before other members of his team. And, Penelope was his friend; he didn't want to give something away if it was supposed to be a secret. "You know that 74% of 30,000 people said they would have an office romance under varying circumstances. And even though two thirds of office romances do not survive, the ones that do have managed to actually retire together."

"And that has you smiling because?" Derek's impatience sounded in his voice.

"No reason. Just thought it was interesting." Reid kept his eyes lowered to hide his glee. He actually knew office gossip! Not that he would ever reveal it. But it was nice not to be the last one that knew something about his team. And, he hoped Penelope and Rossi were happy. He wanted them to be part of that 33% of office relationships that made it.

Hotch strode into the pen with records held in one hand. "We just got handed a case. Everyone to the war room." Turning, he noticed that Dave's office was empty. "Where's Dave?"

Standing up, Derek moved away from Reid's desk as Reid stood up. "Don't know, Hotch. His vehicle is here but he hasn't been in the office yet."

Spellbound, Dave watched as Penelope lowered herself to her knees, letting his hands slide along her arms as she did. Her hands stilled causing him to let out a harsh breath of air, sucking it back in as she leaned down and flicked her tongue in a broad stroke over him. He nearly groaned as he watched her draw back and consider the taste, the look in her eyes a little like the one from when she inhaled her first scent of Scotch. She was pulling ever dark dream from inside him and he was almost inarticulate with need. The element of danger in their surroundings, the unpredictability of the circumstances, and the image of his Goddess before him made him even harder.

Running her tongue under him, and teasing the vein that throbbed there, she followed the path upward. David Rossi growled, his hands desperately trying not to clench in her hair. Sucking lightly, she took him into her mouth, before pulling back and swirling her tongue around him and then descending down over him again. Her hand was wrapped around the base, she took more of him into her mouth.

Reflex caused David to pull one hand from her and pat at his jacket pocket, opening and answering his phone by habit, "Rossi."

Penelope slid down till her bright lips met her hand. Pressing her lips down firmly, she slowly drug her lips back, humming at the bright mark of lipstick she left pressed against Dave's skin.

Dave coughed hoarsely as he lost his breath, the feel of Penelope working him over making him briefly lose track of what else was going on till a voice near his ear broke through his haze.

"Yeah, yeah, I'm still here. I'll be right there, Hotch. I have to go." Dropping the phone after shutting it, he pressed one hand on the wall behind him and slid his other hand deeper into Penelope's bright blonde tresses.

"Fucking hell! Is everyone on the team going to look for us? Damn it, Dolce, don't make me beg, please" Dave hit his head with how quickly he arched in response to her sucking, then the hard licking she followed it with. The sensations were unbearably pleasing, shivers running up his spine. She took him to the hilt and a loud groan filled the room. The fingers on his hand are pressed against the wall hard enough that the beds of his fingernails are white but the hand cupping her head is gentle as she takes him to the hilt again.

"Cara, I can't wait any longer," concerned, Dave pulled gently on the soft hair caught between his fingers, striving to hold off. He felt her moan around his length and looked down to see her eyes at half mast, dark and lazy with sexual awareness. The vibrations of her moan was adding more delight to what he was feeling and he was hanging on by his fingernails to his control till, with a slanted hot look, she sucked back down his shaft, deliberately moaning when she reached the base. One breath, two, and he came, the pleasure to intense.

He kept his eyes locked on hers as she kept moving, struggling to keep his eyes from slamming shut at the pleasure she was giving him. He could feel each movement of her throat as she swallowed. "Cara!" The cry was wrung from him; the hoarse rasp echoing around the small room.

She began to ease away, a smug smile in place. Taking a deep breath, he quickly arranged himself, a shudder sliding under his skin at the circle of lipstick that still surrounded him. Pulling her to her feet, he enfolded her into his arms. Penelope nestled close, listening as Dave's heart rate slowed down under her ear. From above her head, Dave's voice surrounded her. "You are a siren, Dolce. But you are my Siren and I will happily follow you." Leaning down, he grinned, "Now, kiss me. That precious lipstick of yours is currently gracing other places and you owe me a kiss, Streghetta Mia."

(A/N: I just can't get enough of this pair. They seem to really really fit together. I'm hoping I'm staying true to how Penelope and Dave would sound. Opinions? Hope you enjoy the story! KK)
