From the xmasprompts list on tumblr (it's the name of the blog) It's set somewhere after the show, but it could be anytime.
Day 3: Netflix and chill
"The kids are not here, we can netflix and chill!" Chandler seemed really excited while Monica was just confused.
"What?"
"A guy at work told me about it. Come on, they have good movies on it."
"By good, you mean old?" Monica smirked.
"We're not old. We were born earlier than a large part of the population, that's all."
"Very large part for you..." she whispered, still grinning.
"What was that?" Chandler gasped.
"So, I get the Netflix part," Monica said, pretending the last exchange had never happened, "but isn't the purpose of watching a movie to chill?"
"It's different from just sitting and watching," Chandler grinned suggestively but lost his smile at the spark in his wife's eyes. "NOT cleaning."
She faked disappointment, then nudged him in the ribs. "So what, we're eating popcorn as well?" she asked playfully.
"Can we eat popcorn on the couch?!"
"No!" Monica instantly replied, realizing what she had just said.
"Kidding. If you need me to demonstrate the chilling part..."
Chandler leaned on Monica in the couch, and she followed the movement, her back touching the couch when their lips met. She was amazed that, after all these years of being married, his kisses still managed to make her feel that way. Like they kept falling more and more in love with each other, but she was pretty sure they had reached the maximum a long time ago.
"I'm pretty sure we're not respecting the Netflix part..." she managed to say when his lips left hers for her neck.
"Screw it," Chandler muttered, his hand tugging her shirt up. She chuckled under his next kiss, but didn't protest more.
