"Have some pie with that whipped cream, why don't ya?" Casey humorously mused as she entered into the kitchen to find Derek burying his dessert with a massive amount of whipped cream on top.

Derek looked up from his plate – a wicked grin sliding in place. "It's the best part. You can't have pie without the whipped cream."

"Other people want whipped cream too, though," Casey pointed out, crossing her arms as she walked closer to him and his concoction. "Did you use the whole can? It looks like you used the whole can!"

"Not all of it," Derek said as he sprayed some more of the whip directly into his mouth.

"Ew, Der-ek!" she hollered, swatting him to stop.

"How is that 'ew'?" he questioned as he set the can down in front of Casey on the counter.

"Like I said, other people want whipped cream too!" she admonished. "You probably got your Derek-germs all over the nozzle," she said, picking up the aforementioned can to try and wipe the can's nozzle down.

"You have 'Derek-germs' all over you anyway," he said with an amused smirk. He reached over to rub her hip sensually. "What's the difference?"

Casey blushed. "Der-ek," she muttered lowly as she gently pushed his hand away. Although their family knew about them, they were still…adjusting. "Stop. I don't want anyone walking in on us dry-humping or something."

Derek's eyebrows rose to his hairline in amusement. "Is that where that was headed?" Derek asked through a chuckle, stepping into her personal space to wrap his arms around her waist.

"Knowing us…" Casey mumbled into one of his shoulders. They had a tendency to get hot and heavy very quickly over the littlest of touches. Derek often joked that they were like animals always in heat.

"When are we going back home," he whispered huskily into her ear, before placing a few pecks along her neck.

"Der-ek," she said, but this time her tone was soft, breathy even. It drove him mad. "It's Christmas Eve – we're here to be with our family that we haven't seen since Thanksgiving. Plus, we already promised to stay the night."

Derek groaned and stepped back from his girlfriend. "Why did we do that again?" he wondered, turning to his pie to take a frustrated bite.

"Because we missed them, and wanted to spend some time with them," Casey explained. Derek scoffed, causing Casey to roll her eyes. "Well, at least I did."

"Trust me, I love my family, Case, but a man can only spend so much time with Edwin's flatulence, my dad's jokes, and Robby's crying," he said over a mouthful. "Not to mention the lack of sex."

Casey snorted at his last remark. Of course sex would be on his mind – not that it wasn't on hers either, but she was good at pushing it back and focusing on more important things, like spending time with her family.

"How about this," Casey began, stepping closer so that she could wrap her arms around the one that he wasn't using to eat his pie. "If you're good, and at least pretend to enjoy your family time, when we get home I'll let you use as much whipped cream you want for…recreational use…" she finished lowly in his ear.

Derek immediately stopped eating his food and looked over at Casey in confusion. "Recreational?" he wondered aloud.

Casey dipped her finger into the whipped cream mess on Derek's plate and slowly licked it off. "Recreational," Casey repeated, before sauntering out of the kitchen, smirking as she heard the kitchen stool screech backward in a haste. The footfalls of Derek Venturi were soon right behind her.

"Who's up for some real family bonding?!"
