Derek pulled away from their second kiss and gave Penelope's shoulders a gentle push. "I have to go," he said. "Reid's with the girls and I told him I wouldn't be late."

Penelope laughed sarcastically. "Ooooh…no, no, no," she said. "You don't walk up to my door, get me all hot and bothered, and then go traipsing off."

"I got you all hot and bothered?" he asked with a smirk.

"You know damn well you did," she scolded him. "And you're not leaving until you've finished the job."

"Oh, Darlin'. You better believe I'm gonna finish the job," he assured her. "When I can do it right. I'm not gonna even start the job…until I know that we can spend the entire night together."

She rolled her eyes. "Entire nights of sex are waaaaay overrated," she said.

"Then you've been spending them with the wrong person," he informed her.

She groaned. "Don't say things like that and then expect me to let you leave," she said.

He wrapped his arms around her waist a dropped a kiss on her nose. "I'm not gonna do anything until I know I'm gonna be able to wake up with you," he said softly.

She reached for his jacket and played with the zipper on each side. "But we've already woken up together," she reminded him coyly.

He smirked again as he squeezed her tightly. "Yes. And do you remember how much fun it was?" He lifted an eyebrow as he looked down at her.

"For you…maybe. But for me…" She scoffed. "It was…"

"Challenging?" he asked with a laugh.

She laughed, too. "To say the least."

He leaned down again and gave her a quick kiss--on the lips this time. "I have to go," he said again.

She sighed. "Just so you know I am vehemently opposed to this."

"Well, there is one solution," he offered.

"And what's that?" she asked.

He grinned. "You cold give me fifteen minutes to get rid of Reid, and we could wake up together in my bed."

She nodded. "Done."

"Fifteen minutes," he said. "If you're not walking through my door fifteen minutes after I get home, I'm gonna wake up the girls, and we're gonna traipse all over town looking for you."

She threw her head back in laughter, and he couldn't resist, he placed a tender kiss on her neck.

She wrapped her arms around his neck as she lifted her head. "Like I'm gonna miss this," she said.

Twenty minutes later, Derek walked through his front door to Reid sitting on the couch; his bare feet up on the coffee table while he stared at the television screen.

"Hey," Reid said. "You're home early."

Derek nodded. "Because I don't feel very good. You should probably leave."

Reid gave him an odd look, and then realization dawned. "She's coming over!" he said, jumping to his feet.

"What?" Derek asked, avoiding eye contact.

Reid shook his head. "I'm not surprised. Derek Morgan scores again."

Derek rolled his eyes. "Do you have any idea how long it's been since Derek Morgan has scored?" he joked.

"I would have thought you and Penelope had some sort of…friends with benefits thing goin' on.

Derek scoffed. "She's too good for that," he said.

"For what?" Reid asked. "For you?"

"That's not what I meant," Derek said. "And look—you need to go! Thanks for watching the girls." He grabbed Reid's jacked and picked up his shoes, then thrust them at him. He frowned as he looked down at Reid's feet. "Nice toes," he commented.

Reid's face turned red. "Millie talked me into it," he said, defending himself. "I'll get some nail polish remover on my way home." He pulled his jacket up over his shoulders.

Derek held up his hands. "Hey, you don't have to explain yourself to me," he said. "I was wearing fake make up the other day."

Reid laughed. "See you later," he said on his way out the door.

Derek ran up over the stairs taking them two at a time. He checked on the girls—thank God they were fast asleep—and then flew into his own room. He raced to his bed and gave the sheet a tug towards the head of the bed, straightening it the best he could. He fixed the rest of the blankets, then fluffed the pillows and tossed them back onto the bed. He kicked the stray clothes on his floor underneath his bed, checked his nightstand for condoms—they were a few years old (hopefully still effective)—then spun around when he heard the noise in his doorway.

Penelope grinned at him. "Not so on your game when you're about to get lucky, huh?" she teased.

He laughed. She was right—any other time he would have heard a damn mouse creeping around the kitchen.

She cleared her throat. "So…how are we gonna do this?" she asked quietly.

He leaned a hip against the dresser, crossing his arms over his chest. "How do you want to do this?" he returned.

She stepped into the room and closed the door behind her, reaching for the lock. Her hand froze and she frowned. "There's not a lock on your door," she said.

He grinned. "Very astute, Garcia," he teased, straightening.

"Why isn't there a lock on the door?" she asked.

"Because one of my precocious kids locked herself in my room one day and she screeched the entire time I was trying to get the doorknob off. And really, Penelope…there hasn't been any need for a lock on my door."

She laughed. "Chessie?" she guessed.

"Of course," Derek answered.

Penelope didn't know what else to say, so she looked around the room uncertainly.

Derek walked towards her. "Don't look at the walls," he said quietly, putting a finger under her chin. He lifted her face so she had to look at him. "Look at me."

She swallowed past the lump of nervousness in her throat.

"Are you sure you want to do this?" he asked tenderly.

She laughed. "Oh, I'm sure," she said, lifting her mouth to his. Her tongue plunged forth, finding his with sudden desperation. She pressed her body against his, her nipples hardening instantly. She could feel his arousal even through his pants. She wrapped her arms around his neck; he wrapped his around her waist, pulling her against him. He reached for the hem of her shirt and pulled it out of her jeans; she brought her hands down to his chest and after undoing the first few buttons, moved her hands frantically underneath his shirt. His skin was hot beneath her touch, and she ran her hands down his chest, then around to his back and up over his taut muscles.

He reached up and undid her bra, and she pulled back, lifting her shirt over her head and tossing it to the side. He reached for the straps of her bra and pulled them down over her arms, letting it fall to the floor. She reached for his shirt to finish unbuttoning it, but he moved her hands away and instead, gave it a tug. The last few buttons flew off his shirt and he shrugged out of it.

They moved at the same time, reaching for the others pants. They hurriedly undid snaps and zippers, then Penelope pushed her pants and down while Derek did the same. She leaned forward against his body—solid and hot—and he moved backwards, falling onto the bed with his arms around her. She threw her arms out to brace the fall, and when her body shifted, her breasts were level with his face. He lifted his head to one of her peaks, his hot tongue sliding over her skin. His pace was hurried and frantic as he moved to her other breast. She groaned as his tongue worked its magic, then whimpered when he pulled back. "If you don't quiet down, I'm gonna have to stop," he taunted.

She bent at the elbows, her breasts moving closer to his mouth, and with a chuckle, he went to work again. She lifted a hand and reached between them, circling his length with her hand.

"Sweet Lord," he hissed. "Your touch…" He reached down and seized her wrist, pulling her hand away from him. With one swift move, he had their positions reversed and he was on top of her. She bent her knees, opening her legs for him.

"Sorry, Darlin'," he said, as he pushed two fingers inside of her. She was hot, and she was wet…and he wasn't going to be able to help himself. "But I can't wait." He plunged inside of her and she threw her head back with a moan.

"Sweet Lord," she whispered, her hips shooting off the bed. Derek groaned as he filled her, and he pulled back, moving in and out of her slowly and steadily. He had no idea where his control was coming from, but he sent up a silent prayer of thanks. He wanted this to be good—for him and for her.

She reached up and grabbed the pillow on both sides of her head. "Derek," she whimpered.

When he thrust forward again, she cried out and he lifted a hand, covering her mouth. "Ssshhh." But he couldn't help it—he grinned. There was something about a woman who was willing to let go and show a man how much she was enjoying him. "The girls," he reminded her.

She nodded, as her eyelids fluttered closed. He watched as she bit down on her lower lip. "Don't stop it," he instructed her.

Her breathing increased as her body stiffened, and Derek felt her tighten around him. He pulled back, and then drove forward one final time as she cried out his name, her hands coming up around his neck as she clung to him. He fell on top of her, then rolled away so he was on his back, throwing an arm over his head. "Hot damn," he said, his breathing hasty.

"Was it as good as you remember?" she teased.

He laughed. "Are you kidding me?" he asked. "It was so much better than I remember."

She rolled up onto her belly and put her chin on his chest. She grinned at him. "What was the best part?" she asked.

"Honestly?" he returned.

She nodded, smiling softly.

"That it was you," he said, lifting a hand to her cheek. She leaned into his touch and then moved forward to kiss him. "And I have a confession," he said when she pulled away.

"What's that?" she asked, resting her cheek on his chest.

He laughed. "I have never been so frantic that I've done it with my pants around my ankles," he admitted.

She lifted her head and sure enough, his pants were still around his ankles. She couldn't help but laugh at the sight.

"And I forgot how exciting it could be when you have to worry about getting caught," he said.

Penelope returned her gaze to his. "It was pretty hot," she agreed.

Derek was right—she'd been spending her 'entire nights' with the wrong person. And she'd had no idea what she'd been missing. But he hadn't hesitated to show her—over and over again. He groaned as she pulled away from him, grabbing her by the shoulders.

"I have to go," she whispered, backing out of the front door.

"No, you don't," he argued.

But she laughed. "The girls are gonna be up in like…two hours, and you haven't had a wink of sleep."

He grinned. "I'm going on adrenaline," he informed her.

"Yes, well…I'm afraid that's not gonna be enough when you crash this afternoon," she teased.

He sighed. "Just so you know I wouldn't be opposed to a repeat performance. Tonight," he said pointedly.

She laughed. "If you're still awake after the girls go to bed, call me," she told him, starting down the steps.

He grabbed her arm and she gave him a questioning look. "Be waiting by the phone," he said huskily.

Then he watched as she made her way to her vehicle, giving her a small wave as she drove away.

"Daddy?"

Derek yelped as he spun around and slammed the door.

"Who was that?" Millie asked sleepily.

Geez, she'd jumped the life out of him. He'd nearly come out of his skin. "Umm…someone selling magazines," he lied.

She walked over to him and he picked her up. "You OK?" he asked.

"Daddy, can I sleep with you?" she asked sleepily.

Derek's mind went into a panic. Could she sleep with him? He wasn't sure. Was he even allowed to have her on the sheets after what he'd just done with Penelope? He sighed. See, these were the things he wasn't sure about.

"Ahhh…sure," he managed to get out. "Just let me change the sheets."

"Why do you have to change the sheets?" she asked innocently.

Derek cleared his throat. "I had the heat turned up too high and I was sweating," he improvised.

She slung an arm around his neck and put her head on his shoulder. "Thank you for changing the sheets, Daddy. I hate stinky blankets," she told him with a yawn.

Derek kissed her on the top of the head. "I know you do, baby girl," he said as he made his way up the stairs.
