"OK, seriously," Penelope said with a giggle as Derek began to kiss her neck. "We can't be doing this anymore. One of the girls is eventually going to walk in and we're gonna be in trouble."

The door flew open as if on cue, and Millie ran into the room only to stop short at the foot of the bed.

"Millie!" Derek said in surprise, leaning over to shield the upper half of Penelope's bare body with his own. Luckily her bottom half was covered with the sheet.

Millie grinned. "Hi, Daddy. Hi, Penelope!" she said. It had been over two weeks since she'd moved in, and the girls were still thrilled to see her every morning.

"Hi," Penelope said in a sing-song voice.

Derek cleared his throat. "Baby, can you go into the downstairs bathroom and get me some toothpaste please?"

Instead of running out of the bedroom door as he'd hoped, Millie disappeared into her fathers' bathroom and came out with a tube of toothpaste.

Derek forced himself not to roll his eyes as Penelope stifled a giggle. "Can you go downstairs and get daddy the mouthwash, please?"

Millie frowned. "We don't have any mouthwash downstairs, Daddy. Remember when Chessie drank the whole bottle and had to go to the hospital? You said we can't have anymore until we're thirty."

Derek sighed in defeat. "Millie?"

"Yes, Daddy?" she answered.

"Daddy needs some privacy."

"Do you have to go to the bathroom?" she asked.

"Yes," Derek said, latching onto the excuse she'd given him.

She nodded. "Come on, Penelope," she said. "We need to give Daddy his privacy."

Oh, no. "She'll be out in just a minute," Derek said.

"I'll wait for you, Penelope," Millie said sweetly.

Derek yelped when he felt Penelope's fingernails dig into his back. Sweet lord, she'd done the same thing last night, and the thought of what preceded that was making him hard.

"Millie?" he said through gritted teeth.

"Yeah?"

"Get out of daddy's room," Derek finally said.

Millie sighed. "I hate these privacy things!" she muttered as she turned around and started walking out of the room. "You guys have to have privacy all the time."

"You are so putting a lock on that door," Penelope said as Millie shut it behind her.

Less than two minutes passed before the pounding started on the door. "They are so codependent," Derek grumbled.

Penelope laughed. "They're kids," she reminded him. "You still have like…fourteen years left."

Derek groaned as he fell back against the mattress, flinging an arm up over his eyes. "We'll be out in just a minute," he yelled.

But the door flew open once again. Derek and Penelope looked up, expecting to see one or both of the girls. Instead, Emily, JJ, and Reid filed into the room. Penelope yelped and pulled the covers up to her chin. "What is going on?" she asked as Chessie and Millie followed them into the room. Millie tugged at Reid's pant leg and he absently picked her up.

JJ looked around and found Penelope's pajama bottoms and tank top and tossed them at her. "Tomorrow's your wedding day," she informed her friend.

As if she'd forgotten. "And?"

"And it's customary for the bride to not see the groom on the wedding day."

"Well, can't you come back tonight?" Penelope asked, her knuckles white from clutching the sheets.

"No can do," JJ said. "We have the entire day planned."

"Manis and pedis!" Reid said excitedly.

Derek lifted an eyebrow at his friend. "You're in on this?"

"Well I wasn't exactly the mastermind," Reid muttered.

"For once," Derek shot back.

"Come on! Hurry up!" Emily said. "We'll be waiting downstairs."

The three filed out of the room with the girls; Emily swung Chessie up in her arms. "Has anyone ever told you that you look just like Jasmine from Aladdin?" they heard her ask on the way out.

Penelope sighed as she sat up. "I guess I have to go."

Derek grinned up at her. "The next time I see you, I'll be marrying you."

She smiled back at him. "Yes, you will be. Are you nervous?"

He lifted his hand to move a lock of hair behind her ear. "Only that you'll come to your senses and decide not to marry me," he said softly.

Penelope smiled tenderly at him and leaned her forehead down to his. "Lucky for you, I'm not that bright," she teased.

"Thank God," Derek said, wrapping his arms around her and pulling her down onto him.

"Derek," she said breathlessly. "I have to go."

"I can't wait to make you mine," he growled.

"You already have," Penelope giggled. "Twice just last night."

Derek sighed. "Hurry up and leave so you can come back to me," he said.

Millie sighed longingly. "You look so pretty, Penelope."

"Thank you," Penelope returned.

"Just like a princess!" Chessie chimed in.

"But not like Jasmine, right?" Emily teased.

"Oh, no," Chessie said firmly. "You are like Jasmine." Her head turned to Penelope. "And you are Cinderella," she said in awe. Then she jumped up excitedly. "Who do I look like, Penelly-p?" she asked.

"One of the most beautiful little girls in the world," Penelope answered softly.

"And I'm the other one?" Millie asked shyly.

"You're the other one," Penelope confirmed.

The girls were dressed in identical light pink sundresses that matched Penelope's bouquet. They were ankle length and the girls had on white socks with ruffles on the edges. Their white patent leather shoes buckled on the sides. They each had their hair French braided, and it had taken Penelope an awful lot of talking to get herself out of wearing one, too.

Instead, the sides of her hair were pulled up, her blonde curls pulled forward to cascade down over her bare shoulders. Her gown was white satin and the straps lifted to tie at the base of her neck, leaving her back bare. The front was v-neck and the fabric crisscrossed to the waist, where it pulled in and then flowed out over her hips and fell to the floor. It was simple with no beading, but Penelope felt like a princess in it. And the tiara that Derek had insisted she wear solidified the feeling.

"You look beautiful," JJ told her friend as Emily nodded in agreement.

"Thank you," Penelope said, her voice thick with emotion.

"Are you ready?" JJ asked.

Penelope nodded. "I'm ready."

"Girls?" Emily asked.

Both girls nodded enthusiastically.

They all turned to a pounding on the door. Reid poked his head in. "You're late," he said sternly.

Emily laughed. "Fashionably," she informed him.

"Derek's having a mini meltdown." Reid's eyes fell on Penelope. "Gar-cia!" he said appreciatively. He lifted an eyebrow at her and grinned. "Makes me wish I would have shared my yogurt with ya!" With that, Reid disappeared once again as the girls got ready for their entrance.

Derek stood at the front of the church anxiously awaiting Penelope's appearance. He saw Reid out of the corner of his eye with a smirk on his face. He was enjoying every minute of Derek's discomfort. JJ and Emily marched in first, one by one, followed by the twins. The crowd laughed when Chessie used her little bottom to push Millie back on her side of the aisle, but all laughter halted as the wedding march began and Penelope appeared at the open doors.

Derek felt tears forming in the corner of his eyes as he watched her walk towards him. And to think, he'd almost let her get away. He knew he was supposed to wait for her where he was, but he couldn't help it; he took two steps forward to meet her, taking her hand in his with a gentle smile and walking her the rest of the way to the altar. Hotch started the ceremony, but most of it was a blur as Derek couldn't keep his eyes off of Penelope.

But Derek was fully alert when it was time to kiss his bride. He took her face in his hands and smiled tenderly at her, then leaned down to press his lips against hers. Penelope leaned forward, her hands grabbing the fabric at his waist as she sunk into him. She felt Derek chuckle and pulled away when she remembered they had an audience, her cheeks blushing.

She heard Hotch laughing before he finally said, "Ladies and gentlemen, I give you Mr. and Mrs. Derek Morgan!"

There were cheers from the friends and family as they turned to face them.

Derek felt a tugging on his pantleg and looked down. Millie was staring up at him. "Daddy, does this mean I have a mommy now?" she asked.

"Yes, baby, you have a mommy now."

"Thank you, Daddy."

"For what?" he asked, swinging her up in his arms as he took Penelope's hand and led her down the aisle. The rest of the wedding party was behind them, Emily carrying Chessie.

Millie sighed. "For Penelope." She grinned. "She's just perfect!"

Derek kissed his Millie on the tip of her nose. "I think so, too, Princess."

Two weeks later…

"Daddy, what are you doing?" Chessie asked curiously as she walked towards her father. He was kneeling down in front of his bedroom door, the toolbox on the floor at his side.

"Switching the doorknob so that my bedroom door locks," he informed her.

She put her hands on her hips. "But how am I gonna be able to get in whenever I want to if you have a lock on your door?" she asked.

He leaned forward and kissed her on the nose. "That's the point, Darlin'. You're not." They'd been home from Disney for less than two hours, and already Chessie was scolding him. Derek couldn't help but grin.

She frowned. "I don't' like this," she informed him.

Derek laughed. "You don't have to."

She sighed. "What if I lock myself in your room again?" she asked shrewdly.

He grinned at his daughter."I have a key to this one," he told her.

She sighed. "Daddy, can't I talk you out of this?" she asked.

Derek laughed at his little girls' question. She was learning how to use her feminine wiles already, standing there batting her little eyelashes. "Not a chance, princess."

"What's going on?" Penelope asked as she approached Derek and Chessie. Millie, fresh from her bath, followed her into the hallway.

"We just got home and now daddy's trying to make me mad!" Chessie accused.

Penelope laughed. "How's he doing that?"

Derek grinned up at her—his grin that was sure to make her heart skip a beat for many years to come. "I'm getting you some privacy," he said with a teasing twinkle in his eyes.

Penelope gasped exaggeratedly. "The best wedding present ever!"

"I think so," Derek agreed.

Millie sighed and shook her head at Chessie, then went to her room.

"I can't wait until I'm a grown up so I can do whatever I want to do," Chessie muttered, following after her sister.

"There," Derek said as he stood. He lifted an eyebrow at his wife. "What do you say we give this bad boy a try?"

"I say hell yeah!" she agreed. Not bringing a chaperone along with them to help with the girls in Florida hadn't been their best idea. They'd managed to have sex a few times…up against the bathroom wall.

But Derek Morgan wanted to make love to his wife in their bed. And as he walked into the room and locked the door behind him, he proceeded to do just that.
