Thank you all for the reviews for last chapter! ~ Angie

Derek Morgan lay awake in bed, his fingers laced together with his hands resting on his flat belly. He sighed heavily. It was seven fifty in the morning, and still he hadn't slept a wink last night. He'd thought maybe that Zumba class he'd gone too would put him right out, but it hadn't. Which was surprising, since the class had practically knocked him on his ass!

His mind went to the restaurant the previous night with Penelope…his 'best friend.' Not once had she stopped smiling during dinner. For that matter, neither had he. In fact, the whole thing had felt much more like a date than a casual dinner between 'buddies.'

Maybe there was something more between them. Maybe they were having some illicit affair, and they'd decided to keep it from the rest of the team. Maybe…

Dammitt! he thought to himself. Here she was, being nice to him, sweet as can be, and here he was, thoughts of sexual escapades dancing through his mind. He really needed to get a grip. But most of all…he needed sleep! But the only way he was going to get that was if he was so exhausted he couldn't possibly keep his eyes open. He needed a good workout.

In fact…he'd seen a sign last night advertising more class times. He'd be a few minutes late, but that would be OK…they probably wouldn't say anything if he stayed near the back. Derek sprung up out of bed, quickly brushed his teeth and washed his face, then found a pair of workout shorts and a t-shirt.

He knew he was in the wrong class as soon as he opened the door. Gone was the Latin beat from last night. Instead a slightly slower beat filled the room, and every woman in the class had a chair placed in front of her. His eyes immediately found Penelope at the front of the room, and his jaw nearly dropped.

Instead of the baggy sweatpants and sneakers she'd been wearing the night before, she was sporting a fitted tank top and a pair of shorts coupled with silver strappy heels, rhinestones creeping sexily up the center of her foot. The heels on them were as high as her shorts were short.

She may not have been the smallest woman in the room, but she was easily the sexiest. From where he stood, he could see the prominent muscles of her legs as she stalked purposefully forward until she reached her chair. She marched a few steps in place and the motion, though simple, was incredibly seductive. Her hip cocked first to one side, then the other before repeating the motion.

"Ladies," the instructor said interrupting his thoughts. She spoke in a voice just loud enough to be heard over the music. "Remember to close your eyes for this next move. Keep a single finger on the back of the chair, stroking it softly while you circle around to the front."

Derek swallowed as he watched Penelope run her finger leisurely across the metal, coming to a halt when she reached the front. She turned to face forward, then squatted down and perched herself on the edge of the chair with her hands on her knees. She spread her legs as far apart as she could before closing them once again and standing. She lifted her arms in the air, shaking them back and forth with strong movements as she moved her lower body simultaneously.

And just when he thought it couldn't get any better, she shimmied her way down to the floor and onto her belly before rolling onto her back. She lifted her knees until they were at a ninety degree angle, and then resting her hands on her lower thighs, she once again spread them.

Derek licked his lips instinctively—this was almost more than he could take. And he would have stayed to watch more…if something hadn't come up.

"I don't believe it," Derek said after a full five minutes of silence.

"It's not a big deal," Penelope assured him, rubbing his shoulder. "In fact…I think it's kind of sweet that you're in touch with your softer side." Oh, she was having so much fun with this! She knew she shouldn't be, and she truly missed her best friend, but she'd never get another opportunity like this.

Derek gave her a look of disbelief. "Softer side?" he practically spat. "I'm a pussy! No self respecting man would watch a movie like that!"

Penelope rolled her eyes. "Spoken like a true alpha."

"You know what? I'm glad I have amnesia!" Derek exclaimed.

She couldn't help but giggle at that. "You are not."

OK, well, there was some truth to that. He hated this amnesia thing. He wanted to know just exactly what was going on between 'Derek Morgan' and Penelope Garcia. Had they really been just friends? Because he'd been sitting next to her for the last two hours and two minutes and all he knew was that her smell was so exhilarating he wanted to bury his face in her neck and suck in as much air as he possibly could. He really should do 'Old Derek' a favor and hit on her. It would serve the bastard right for never making a move. Especially after seeing her in that damn class this morning. What a wake up call!

He reached forward from his spot on the floor and grabbed his glass of wine off her coffee table. Again, he couldn't help but think how very 'date-ish' this was.

Penelope laughed. "Would it make you feel better if we watched 'Con Air'?"

"Sure," he agreed.

She nodded, and then stood, walking over to the cabinet that held her DVD collection.

"What's 'Con Air?'" he asked with a frown.

She pulled the movie out and turned around. "Guns and cons," she said.

"Now that sounds like something I'd like," he commented with a grin.

She laughed as she put the movie in the player. "We'll get that masculinity back up to par yet," she assured him.

She walked back to the coffee table and grabbed her wine glass. "Refill?" she asked.

Derek sat there for a moment studying her face before finally handing her his glass. "Thanks," he said.

She couldn't help but wink at him as she took it.

"How am I not in love with you?" he asked. He hadn't meant to; the words had just flowed forth. Oh, 'real Derek' was going to kill him!

Penelope cleared her throat as she straightened. "We don't know that you're notin love with me," she said in a teasing tone as she threw a sexy smirk over her shoulder on her way out of the room.

Derek jumped to his feet, quick to follow her. Thatwas just too much for him to resist. "What do you mean?" he asked as he entered the kitchen.

She couldn't help the grin on her face. "We don't know that you aren't crazy about me...only that we're not together. For all we know, you harbor all of this pent up lust for me."

Derek couldn't help but grin. And after seeing her in her class earlier today, those turquoise colored shorts and yellow tank barely covering her lush body, he could believe it.

And what's more…he liked the sound of it.
