A/N - This was intended to be a one shot, but so many people wanted a sequel that I had to oblige. There will probably be 2 more chapters.
Derek looked up and smiled as he looked across the bullpen and watched his wife exit the kitchen and stop to chat with Agent Anderson. He'd never really seen the mythic pregnancy "glow" in anyone until his baby girl was carrying his child. Although, he reasoned, she sparkled before, so it was no surprise that she was glowing now.
As if she felt his eyes on her, she turned and winked at him. She patted Anderson on the arm and bounced across the room to his desk.
He groaned quietly as he felt his pants tighten. She had only gotten more sexy as the months went on. Her breasts had swelled and she'd gotten even curvier. He could barely look at her when she was getting dressed or, God forbid, coming out of the shower. It had gotten so bad that he was slipping out of bed in the morning to relieve the tension before she woke up so that he wouldn't jump her.
"Stop it," he told himself. "It's just not right for you to be lusting after your PREGNANT wife."
"Hey, hot stuff!" she said cheerfully. "How's it hanging?"
"Oh, baby, it's hanging just fine." He replied with a grin. The banter, and the sexual frustration, were familiar. It was almost like before they'd admitted how they felt about each other.
It took great effort for him to keep his eyes on her face as she leaned on his desk. Her always magnificent cleavage had gotten stupendous. Her growing breasts overflowed the cups of her bra and he couldn't help sneaking glimpses whenever he could. He missed the time where he could take a good long look and know that he would be seeing more of her later.
"Oh, sweetness," she cooed, "I haven't seen it hang for a while now and Mama misses her chocolate."
Derek's eyes darkened at the look in her eyes. He knew that look. He'd seen it in her eyes right before the first time that they had sex in her office. He'd seen it when she dragged him into a server closet during an FBI seminar, twenty minutes before her presentation. It was a look that meant that he was about to be a very happy man.
Derek started to lean into her, then suddenly, he remembered – pregnant, delicate, wife. He couldn't bury his face in that milky bounty and play motorboat. She was pregnant and he had to respect that. He leaned back with a smile and said casually "Well, with this pile of files I've got to get through, I don't see that happening any time soon."
Penelope straightened up slowly and took a deep breath. She smiled sadly and said, "I remember when you wanted to be with me more than anything, especially work."
"Oh, baby –" Derek started, realizing that he'd hurt her.
"No, it's fine. I understand," she interrupted, vaguely gesturing towards herself and backing away.
"Penelope, wait," Derek said. He was distracted by Hotch walking up to them.
"Morgan, I need you in the conference room," he said. He then looked at Penelope and noticed the look on her face. "Everything okay?" he asked.
Penelope smiled tremulously and said, "Fine, boss man. Your theory was just wrong." She turned and hurried back to her lair, Hotch and Morgan watching her go.
