Erin stirred, it taking a moment for her to realize that the hard surface her cheek was imbedded on was Jay's chest. But as that realization washed over her – as she felt his chest cage rising and falling slowly under her in his sleep, she smiled softly. She lay there for a moment – feeling it and listening to his breathing and slow rest heart rate under her ear.

Then, though, she let out a long yawn, allowing her eyes to drift open more. It was full daylight. The open curtains were allowing some grey sunlight to stream it, though it was still battling a thick overcast outside. And, even though the blinds had been left open, all the wind and falling snow had caused the flakes to accumulate in a pile on the windowsill of her old bedroom, blocking the bottom half of the window with the snow pile.

She propped herself up on her elbow a bit and strained her neck to peek across the room and try to see out the window. But the old window was coated with frost that had made snowflake panels against the glass too. She couldn't see out it very well to gauge how much snow had been dumped on the city. At least it wasn't rattling at the moment. The wind from the storm had died down, so hopefully that meant the snowfall had stopped too. A white Christmas. That was kind of nice.

She stretched and leaned over to her bedside table, retrieving the water bottle she'd left there. She cracked the lid off and took a long gulp. Forcing herself to wake and to center herself for the day. She could already hear movement downstairs – and smell the starts of Hank's Christmas Day breakfast. It smelled fantastic and her stomach growled with it. She suspected it was likely the aroma that had lulled her awake in the first place. Though, she wondered why she hadn't been awoken earlier. With how bright the room was, it definitely wasn't the wee hours of Christmas morning that Ethan usually had them up for to excitedly unpack stockings and open his presents. But they hadn't really been home and settled until the wee hours of the morning – just a few hours before he normally would've been up for the day. And, she suspected he wasn't entirely in the Christmas spirit that morning. He probably wasn't feeling very well.

She found herself gazing at Jay while she woke. She was almost surprised he'd actually stayed the night. She'd sort of expected him to bail. But there he was. Sprawled on his back, bare-chested and not stirring at all. Well, almost not stirring at all. Something had clearly stirred in him. The blankets at crotch level were visibly tented with his morning erection. She smiled a little at that. Gazing at it for a moment and then reached over and set the cap of her water bottle on top of it, nudging it a little to get it settled right at the apex. Jay mumbled a bit at the interruption. But she ignored it until she got the cap in place and then shook at his shoulder.

"Jay," she said and he just muttered and stirred ever so slightly. "Jay!" She shook him a bit more firmly.

"What?" he groaned angrily, his eyes still tightly shut. He so wasn't a morning person. Most mornings, in her experience, he was barely bearable until he had at least two cups of coffee.

"It's Christmas," she told him.

He groaned again and repositioned slightly, throwing his one arm over the back of his head. The movement only caused his erection to stand up a little straighter, the cap still hanging off it unnoticed. But it made her juvenilely smile at it while he still lay there with his eyes closed.

"What time is it?" he muttered, sounding just slightly more awake.

She picked up her phone off the nightstand and looked at it. "Almost 10," she informed Jay.

"Mmm …" he groaned. "Wake me up at New Year's."

She gave him a little swat. "It's Christmas. You need to wake up."

"No," he mumbled at her.

"Well, you at least need to deal with that," she said and pointed at his dick.

"Deal with what?" he muttered.

"That?" she said again.

He let out a slightly annoyed groan but opened his eyes to slits and looked at her. She caught them and gestured with them at his crotch. He lifted his head a bit to look down his chest. He groaned at her and gave her an unimpressed look.

"Decorated the ornament for you," she informed him.

He just groaned at her more, and batted the cap away. She just smiled and took another long swig of her water.

"C'mon," she ordered. "Time to get up."

"I am up," he said and gestured absently at the hard-on while closing his eyes again.

She swatted his shoulder. "Deal with that so we can go downstairs," she ordered.

He rotated his head toward her and squinted at her. "I got some ideas on how to deal with it," he said.

She gave him a grin and leaned into him until her mouth was just inches from his face, her hand snaking under the blankets.

"You mean like this?" she teased and found him, griping the girth of him and then stroking his length, while her tongue tip traced a pattern in that soft spot just below his ear.

He let out a quiet groan and she felt his hips involuntarily press up into her hand while his head fell back farther into the pillow, leaving more of his stubbly jaw available for her to suck on.

"Yes," he pressed out in an already shifted breathing pattern. "Merry Christmas."

She smiled against his neck at that and moved her mouth to his, kissing him passionately and allowing him a few more seconds to enjoy the starts of the handjob. But then she pulled her mouth away from his demanding lips, them making an almost disappointed suction noise as she did. He clearly knew what was coming and was trying to keep her attached to him as long as possible. She stroked at his bedhead, and smiled at him, looking into his little boy eyes that were reflecting some frustrated disappointment.

"Merry Christmas," she agreed. "But I meant think about baseball or go take a leak."

She shifted away from him, his hand landing on her lower back as she sat on the side of the bed for a moment.

"You are such a tease," he informed her.

She shot him a smile and rose from the best, starting to search for a clothing option that would be more presentable in front of Ethan and Hank than her current outfit of panties and a braless tank top, her nipples standing on end from the slight chill in the room and the slight simulation from the starts of what her and Jay weren't going to continue.

"Later," she promised.

He groaned. "When later?" flinging his arms out to either side, spread eagle as he took up the whole vacant space.

But she just smiled again and put her hands on the mattress and bounced it a bit.

"C'mon," she said, as she bounced it, him giving her an annoyed look. "Get up, get up. I want to open my stocking."

He gazed at her again for a moment. She thought she was going to have to continue to prod him. But then he suddenly at up, scrubbing at his face.

"OK," he agreed.

She looked at him and pointed. "You still have to deal with that before we go downstairs," she stated flatly.

"Yea," he muttered from where he was now sitting on the edge of the bed. He rose and wandered toward the door of the room, his hand down the front of his boxers, as he adjusted himself. He opened the door and looked both ways before wandering out into the hallway in the direction of the bathroom. "I'm on it."

"Don't piss on the floor," she teased after him, pushing the door shut behind him so she could finish getting dressed.

"Ha, ha," he muttered, the bathroom door clicking shut.
