This chapter sort of got away from me and didn't exactly go where I thought it was going to, but I think it was fun, anyway! I hope you enjoy it! Thank you for the reviews for last chapter! - Angie

Derek tried not stare—he really did, but it just wasn't working. Penelope was sitting there with a sultry grin on her face, her eyes already shadowed with desire. As remarkable as that image was, it was her body that demanded his attention. Her blonde curls fell down over her shoulders, stopping just above her breasts; it didn't escape his notice that her nipples were already taut. He swallowed past the sudden lump of yearning in his throat as his gaze travelled down her belly. He could just see the soft cluster of curls peeking out from her red snowflake covered panties—barely there panties that were already moist in anticipation. He lifted his eyes to her hers again before dragging them down over her body, then repeated the exploit a few more times before a knock at the door jarred him from his gaping.

"Penny?" They heard Payton say softly.

When she heard her brother's voice, Penelope's eyes immediately widened. "Oh, no!" she whispered urgently, looking around frantically.

Luckily Derek was trained in such matters. Well, not exactly such matters, but he had been schooled over and over again in how to react in pressing situations; his common sense once again served him well. He sprung out of bed and threw Penelope's nightdress at her. She started to pull it on over her head, but he grabbed it form her. "No time!" he reprimanded, thrusting the article up under her pillow. "Get under the covers!" he instructed.

"But—"

"If your brother walks in here and sees you like…" He swept an arm in her direction. "This—my man parts are as good as gone, and I happen to like them exactly as they are," he hissed. "Now get under the covers and pretend you're asleep!"

The look he gave her was so authoritative that Penelope did as he'd told her to do, pulling the covers up to her chin and facing away from the door so Payton wouldn't be able to see her face. She was sure her cheeks were flaming red.

Derek grabbed a t-shirt from his bag and pulled it on over his head as he made his way to the door. With one last glance at Penelope to ensure she was securely under the covers, he pulled the door open a crack. "Hey," he said to Payton in his best 'I'm not going to sleep with your sister voice.' "What's goin' on?"

"I just came to check on my sister," Payton said, trying to move into the room.

Derek stepped to the side, effectively blocking him. "She's asleep," he whispered.

"Well, is she OK?" Payton pressed.

Derek shrugged. "Oh, yeah. I think that creep might have made her a little anxious. She probably just needs a good nights sleep," he commented.

Payton nodded in agreement. "OK," he said. "Well—thanks for keeping an eye on her tonight."

Derek nodded, feeling like a heel. His eyes had been on her alright—all over her. "No problem," he said.

"I'll see you at breakfast," Payton said, turning to go.

It took every ounce of Derek's strength to close the door gently. Then he locked it and turned around. As soon as he did, Penelope threw the blankets down to her waist and flew up in bed. He was greeted with the sight of her breasts again; this time they were swaying from side to side in the most marvelous way. "Is he gone?" she asked breathlessly.

"He's gone," Derek confirmed, purposely keeping his eyes locked on hers. Do not look directly at them, he tried coaching himself. "Put your nighty back on," he commanded, leaning against the door. Distance was good, and this was as far away as he could get from her and still remain in the room. But her body was so damn persuasive, he was beginning to wonder if the hotel lobby would even be far enough away from her.

She shook her head. "It's too…constrictive," she announced.

"Penelope, I swear to God—"

"But if I have it on, I can't do this." She lifted her arms out to her side and shook her upper body back and forth.

Derek groaned. Was she really doing this to him? "I think maybe I should have been the one who was warned about you," he growled.

She grinned at him. "Yes, but I appear to be all innocence."

"Woman, the way you look right now is anything but innocent," he informed her.

"Just kiss me," she pleaded. Her words were innocent enough, but then she returned to her former position on her knees, her hands splayed over her upper thighs, and all pretense of virtue vanished.

He shook his head firmly.

Penelope tilted her head to the side. "What's one little kiss?" she asked.

"The start of something explosive," he answered.

She nodded her head as she moved to the edge of the mattress and then made her way to her feet. "I like explosive," she disclosed huskily, slowly moving toward him.

He held up a hand. "Please," he rasped.

When she reached him, she grasped his wrist with her hand and moved it down to his side, then stepped forward so the tips of her breasts just touched the fabric of his t-shirt. She looked up at him, wide-eyed. "Did you know I've never had an orgasm that I didn't give myself?" she asked.

Derek licked his lips before he could answer her. "I…did not know that," he said, barely able to get the words out.

She nodded fervently. "It's true," she assured him. "That's not to say I haven't been with men, because I've been with my fair share. But I've only ever climaxed…" She winced. "Under self-induced circumstances. What do you think that says about me?"

That was too much of a challenge for a man like Derek Morgan to ignore, so he tangled a hand in her hair and tugged her head backwards so their eyes met. "That you've been fucking the wrong men," he bit out before his lips came crashing down onto hers.

Her mouth parted underneath his immediately; his tongue thrust forth with every bit of pent up passion he'd been feeling since he'd walked into their hotel room to discover her perfectly shaped ass wobbling in the air. His hands moved to her cheeks as he tried to hold her still—he couldn't seem to kiss her hard enough.

His entire body tensed up when she lifted her hands to his waist, caressing his flesh with her delicate touch. Her hands roamed up over the corded muscles of his back until she was clutching his shoulders from behind, the motion crushing her breasts further against his chest.

In a fleeting moment of sanity, he pulled away. "Penelope—" he said, his breathing ragged.

"I've never had a one night stand before," she told him.

Sweet Lord, was she always so direct? "Are you sure you want to now?"

She shrugged a single shoulder, unknowingly batting her eyelashes at him. "Well, I was thinking that if we slept together tomorrow night, too…" She let her voice trail off suggestively.

Had Payton still been standing in the hallway, he would have heard Derek's shout of laughter.
