A/N: This is NSFW (Rated M or NC-17). Thanks to CatzzCK for the idea to do another smutty kind of one-shot like I did last year. Enjoy! ;)

Casey walked into her shared apartment with Derek, shaking off the snow that clung to her coat and reveling in the warmth of her home.

"Derek?" she called out, putting away her coat and other accessories.

"In here!" she heard from their living room with the sound of tape being pulled and ripped off.

The eldest McDonald sibling raised an eyebrow at the noise as she walked through their mini foyer area and turned the corner into the living room. There she was greeted by a shrew of wrapping paper littered all over the ground, along with tape bunched up or sticking to various surfaces. And in the middle of it all was Derek, sitting down, smiling up at her with the most hesitant smile she had ever seen grace his face.

"Hey, Case," he greeted lightly. "How was work?"

"Why does it look like Christmas threw up in my living room?" Casey heavily questioned, completely ignoring Derek's question as she stared at the monstrosity of a mess more. "Der-ek, what are you doing?!"

The former hockey player sighed, wringing the back of his neck. "I was trying to wrap your present," he said with a shrug. "But obviously I'm not very good at that…" he added, gesturing to the clutter.

Suddenly the anger that had bottled up inside her had extinguished. "Aww, Derek," she let out, her eyes getting starry as she looked at her boyfriend lovingly. "That's so sweet."

Derek rolled his eyes at Casey's massive mood swings, though was grateful for it today.

"So…" Casey began eyeing the living room again, "did you ever get around to wrapping it?" she asked, not seeing a gift in sight.

"Yeah," Derek answered, handing her the living room's throw blanket.

Casey raised her brow, puzzled. "Derek, this is our blanket…"

Derek nodded his head, taking it from her and setting it down. "Yup, and your gift is tucked away safely inside it." When Casey gave him an incredulous look, he further explained. "I ran all out of wrapping paper and didn't have enough time to get more!"

Casey sat back on her heels, thinking for a moment, before she fell into a fit of laughter. Derek, meanwhile, was staring at her worriedly, wondering if he had finally broke her.

"I feel like I should be kinda mad about this," Casey confessed, still laughing minimally. "But this whole situation is just too funny," she continued, walking up to Derek and wrapping her arms around his neck. "I appreciate the effort though," she told him, leaning up to give him a quick kiss. "But maybe next time you should just get a bag."

He smirked, wrapping his arms tightly around her waist. "Duly noted."

"So, what did you get me?" she curiously inquired, pursing her lips.

Derek shook his head. "It's not Christmas yet. Can't tell," he said.

She lightly frowned, pouting thoughtfully. "Well…what if I worked for it?" she asked, her big blue eyes a couple shades darker than usual.

"Work for it?" Derek wondered, not quite understanding what she meant. "You were just at wor-oh!" he let out, surprised as Casey's hand felt up his penis through his sweatpants. "Damn, I've really corrupted you, haven't I?" he breathed out hotly, looking at her intensely with lust.

"Mmhmm," she hummed out, reaching up to kiss him on the lips, her teeth latching onto his bottom lip as she sucked.

"Fuck, Case," Derek let out once she trailed her lips down his neck, sucking on a spot near the bottom. His dick had already made a pretty tent in his pants and she had barely touched him.

Her hands tugged up his shirt, which he happily helped take off, watching her mesmerizingly as she felt up his chest, ghosting her fingers up and down. She took off her own shirt, her eyes half-lidded in her desire as she watched him watch her.

She knelt down on her knees, her hot tongue running along the contours of his abs, her chest consequently rubbing up against his erection. Derek let out a moan.

Casey tugged him down with her, guiding him to lay down on the floor, becoming one with the living room mess. She got on top of him, straddling him as she leaned down to kiss him fully on the lips. Her hips rocking against his own; he could barely stand it.

She smiled down at him coyly, as if she knew what she was doing to him, purposely making him crazy. She then reached behind her back as she unhooked her bra, letting her breasts fall free. Her erect nipples grazed his chest, making his dick twitch as she kiss once more.

"Case," he let out with a groan.

Smirking, her hands hoisted down his pants, right along with his boxers. The sudden chill of the air against his private made him shiver momentarily, but Casey's hot mouth quickly compensated as she went down on him.

His eyes rolled back as he felt her lips move up and down on his dick, her hands moving and coinciding with her mouth. He leaned up, looking at her head bob up and down, her breasts on full display, hanging beautifully when she raised up – he was spellbound.

She's done this to him countless of times – they had been together for a while now – but there was just something different about it this time. He sounded like a girl, but it almost felt magical with the lit Christmas tree right behind her and all the flashy wrapping paper surrounding them.

"Fuck," he let out, the pressure building, his stomach tightening. "Case, I'm close," he warned.

Only moments later he released right into Casey's mouth, his girl taking it and swallowing it like a champ. She grinned impishly as she finished, wiping an excess off the corner of her mouth that almost caused him to pop another boner.

"So," she said, her eyes still hooded as she regarded him, "can I find out what my present is?" she asked, softly, seductively.

Derek barely had words, his mind blank. "You-You can ask or do whatever you want," he said, to which she laughed, rolling her eyes.

"You're so easy."
