Part 1
Christmas Eve

The first time it happened, he was drunk.

Well, not exactly drunk, but he was definitely tipsy and he'd had his fill of eggnog.

Okay, it wasn't just eggnog… He'd gone to Socko's for the first half of the day and they'd sipped beers the whole time, so he was already feeling it by the time Socko brought him home. Then he'd hit his stash of wine with Mrs. Benson, and then once she'd left, he started on the eggnog – which he'd made a separate batch of for the "adults" that was stronger than normal and that he kept away from the kids' eggnog that was non-alcoholic. And well, he didn't drink very often, so he tended to be a lightweight when it came to alcohol.

The room was getting blurry and he had a feeling he was starting to reach the tipping point, so he left the Christmas party that was commencing in his living room and slipped into his bedroom. He kicked aside his shoes and pulled his shirt over his head, tossing it into the hamper across the room. He fumbled with the button of his pants, finally undoing it and admitting to himself that he had probably had a little too much alcohol for Christmas Eve.

He then turned around to see what time it was. Just as he did, a flash of blonde hair caught his eye. He looked to the door to see Sam standing there, a look of mischievousness in her eyes. Her back was to the closed door and she had a cup of eggnog in her hand. He paused when he saw this because he recognized it as the adult eggnog, and hadn't he made it clear that it was just that – adult eggnog?

When he realized that her eyes were trailing down his body, he remembered he was missing his shirt and his pants were unbuttoned. He looked down and moved to button them back up, but a force suddenly pushed on his chest and directed him to the side, shoving him against the wall to his right. He gasped, but his open lips were shushed when another pair of lips pressed against them.

Sam was in front of him, pushing him into the wall, holding him against it and pressing her lips against his. He had instinctively shut his eyes and ceased breathing for the moment, completely taken aback. Her unruly blonde hair was tickling his cheeks and chest, and her slender body was pressed up against his. He realized she'd set her now emptied cup of eggnog down on the floor near the door.

Slowly, he came to the realization of what was happening and gently placed his hands on her chest, pushing her back. He opened his eyes and stared down at her in shock. She stared back up at him with hungry blue eyes. Her lips were glistening in the dim light of his bedroom.

"What-what're you doing?" he stammered out in a hushed voice, finding that there was more than alcohol hindering his speech.

She placed a thin finger to his lips, shushing him, and moved it only to kiss him once more. She moved her hand to the back of his head, gripping a handful of silky hair between her fingers.

He tried not to give in, but it was useless. As Sam pressed her lips harder into his – pressing her body into his just as hard – he started to kiss back. He could feel all of the blood flowing into that certain region, which wasn't making this any easier.

Without thinking, his hands wandered down to her slender hips, gripping them possessively. He was suddenly very aware of how curvy Sam had gotten over the past few years. He had already been aware of it, but without the alcohol taking away his inhibitions, he didn't like to admit to himself that he was even acknowledging the maturation of his little sister's best friend. It just seemed like territory he wasn't supposed to cross into.

But then again, she had already crossed that line.

He gave up trying to push her away and instead pulled her in closer, their bodies merging. The fabric of her striped sweater was soft against his skin.

After that, there were only bits and pieces that stuck out in his memory.

He remembered stumbling around and hushed whispers after she'd flipped off the light. He remembered slipping past the fabric of her clothes and reaching her even softer skin, marveling at how it felt beneath his fingertips. He remembered how the inside of her mouth smelled and tasted like eggnog with a hint of Captain Morgan. He remembered entwining her blonde hair between his fingers and leaving trails of kisses all up and down every part of her body that he could reach; how her skin smelled like blueberries when his nose was right up against it. He remembered the chills the sound of her quiet moans sent up his spine. He also remembered how surprised he was when he realized what kind of panties he'd just slipped off of her.

He definitely remembered the scratches her long nails left on his back, and how messy she'd left the bed. He remembered waking up a few hours later, still drunk, and finding her gone, nothing to indicate she'd even been there. For all he knew, it all could've been a dream and his own restless sleeping that left the comforter on the floor and the sheet wrapped around one of his legs.

But when he woke up, hungover, and joined his little sister and her best friend in opening Christmas presents, he decided to act like he didn't remember any of it.

Because as far as he knew, she didn't.
