Niagara Falls was like a trip to the water park. Or SeaWorld. Anyone who came within five feet of the railing would get soaked. Casey, however, did not know this. And because his beloved Casey did not know this, he used it to his advantage.

"Hey Case." He said, his fingers loosely hanging by his pockets, "Did you bring that white tank top?"

Casey wrinkled her nose at him in confusion. "You mean the one that barely fits me? Yeah. But I was planning on sleeping in it."

He grinned at her, his charm on full wattage. "Wear it, babe."

And, growing weak-kneed at his pet name, she obliged. She, of course, changed in the bathroom and left him to his own imaginative devices as to how the scene would unfold.

However, those devices became a little too stimulating, and he had to think of dying puppies for the rest of the time Casey changed.

She exited the room, and he drank in her bare skin. Maybe this had been a bad idea. She threw on a blue hoodie, zipped it up part way, and smiled at him. Did he detect a sense of evilness in those eyes?

"Ready to go?"

"Mm." he uttered, the sound coming out strangled and breathless. Damn it.

He held the door open for her and stayed a few paces behind. Needless to say, his eyes were not on the path outside, and he walked into the staircase.

Casey grinned. "I'll be at the car, Der."

The man at the desk glared at him—and Derek mirrored his actions.

"I'm never volunteering at an old people's home, Case. They're all evil." Derek said, once he'd gotten to the car. He rubbed his forehead.

Casey swatted him. "You're mean. Old people are nice."

"To you, of course. The old guys probably want to bang you and the old ladies probably think you're so damn cute, just like their thirty thousand year old daughters."

"Derek!" Casey protested, frowning. "Gross!"

"Yeah. Thirty thousand year old women—pretty gross."

Casey simply rolled her eyes at this.

"Wait! Go back to that gas station!" Casey said suddenly, and Derek nearly rammed into the car in front of him.

"Never do that again, Case." He muttered, taking a left and pulling into the parking lot. "What do you need, anyway?"

"Disposable camera. I want to get some pictures."

"You mean Girl Scout Casey forgot to pack a camera?"

"Oh, shut up. I saw your Campfire Kids photos."

"That never leaves this car."

She left with a victorious smile. Derek sighed, the sigh dwindling into a whine. Couldn't she see she was killing him?

The tank top was a bad idea. Casey got into the car, and her jacket was zipped all the way down now, exposing glimpses of her toned stomach and shoulders. Derek gulped.

"Let's go." He said in a strangled whisper. Casey chose not to comment—but she did smile at him innocently, pulling on her seatbelt in a fashion that drew the most attention to her chest.

You are so evil. Derek thought whiningly.

"Quick, Derek, let's get a picture of us here!" Casey said, grabbing him into a pose and clicking the camera.

"I didn't even smile." He said flatly.

Casey stuck her tongue out at him. He briefly wondered how skilled she was with her tongue and mouth in general…

"Let's get closer." He blurted out, dragging her to the crosswalk.

They crossed, Casey grabbing his hand, and feeling his tension. Casey smirked at this, but said nothing.

He dragged her to the railing, where the falls were in all their glory, and Casey's eyes lit up. "They're beautiful!"

He didn't even look. Casey looked at him. "Aren't they?" she asked.

"Oh. Uh. Yeah."

She turned his back to the railing, and pressed her own back into him. He could feel her warmth and could smell her hair. Resting his chin against her shoulder (which was sadly covered by her parka, he noted), he faked a smile.

"Ready?"

"Take the picture, already!"

She pressed against him harder. He focused on not letting his smile falter.

"Cheese!"

An hour and a half later, Derek got his revenge. The camera was full, and Casey was soaked to the bone. Her hair hung limply at her sides, and her makeup was running. She had, of course, zipped up her jacket long before she got this soaked, but her pout was worth it.

At the hotel, as he shut the door and locked it, Derek smirked and said, "Nice outfit, Case."

"Shut up, Derek." Casey muttered huffily, peeling off her jacket and hanging it up to dry. "Just for that cruel trick, I get the first shower."

He looked at her, his gaze on her heavy and muddled. "Why don't we share, Princess?"

Casey rolled her eyes. "You wish. No rewards for tricks, Derry." She said, closing the bathroom door in his face.

Derek sighed at this and began to change, hanging up his own wet clothes to dry as he pulled them off. Clad in a pair of jeans, he thumbed through the TV guide and flipped to a hockey game, watching it with only a mild sense of interest.

His real interest exited the bathroom with only a towel around her—and the towels hotels usually got were so tiny they barely covered much. Hallelujah, Derek thought.

"I forgot to bring a new set of clothes in with me," Casey said sheepishly, watching his roving gaze with a sense of embarrassment.

"You do recall I've seen you naked quite a few times?" Derek pointed out with a smirk, "And that I like you naked?"

She raised an eyebrow, sauntered up to him, and kissed him, pulling his shirt off. He tugged the towel away from her.

"So convenient," he murmured, smirking as she undid his belt, "So impatient."

"Talking too much," Casey replied, pushing him backward and silencing him with her lips, moving them lower slowly.

Take-charge Casey was hot, Derek realized, before coherent thought became difficult.

o-o-o-o-o-o-o-o-o

"You know, I'm hungry." Derek said.

"You're supposed to be all romantic during pillow talk, Derek, not tell the girl you're hungry."

Derek stared at her. "But I am hungry."

Casey rolled her eyes.

"Okay, okay. You're beautiful and I love you. Now cry, so we can get dressed and order pizza."

Casey glowered at him, but smiled anyway, like he knew she would.

"How about we get dressed and lie in bed and have pillow talk while we eat pizza?"

"A fine idea," she said, looking on her phone for the number of a pizza place.

He kissed on the cheek. "Clothing for you is optional."

She swatted him.

"Likewise, Venturi." She whispered.

"Pizza." Derek whispered back, and reached for the phone.

Casey surrendered with a laugh. "I want the Hawaiian style."

"Pinapple on pizza? Gross. I want the Meatlover's."

"You mean, a heart attack on a slice?"

"Half and half?"

"Deal."

Derek ordered, and she slipped out of bed, the cold air causing goosebumps to rise on her skin.

"Domino's? Never mind." Derek said.

"What was that all about?" She asked, reaching for a shirt.

He eyed her hungrily. "Pizza doesn't sound so great anymore. You're on the menu."

He grabbed her wrist and drugged her beneath their sea of blankets. And this time, Casey would be the one slipping into an exhausted slumber.
