Set early Season 5, most of them before Joey found out about Chandler and Monica.
It's just a handful of short fics with ideas I had about them having to hide their relationship. It was fun to write and if you have a random idea about that, don't hesitate to submit it :)
Chandler grinned as he deepened the kiss and Monica groaned. He ran his hands a few more times up and down her body, then slipped them under the now very frustrating clothes getting on his way. He probably prided himself a bit too much with the way he could make her whimper just by kissing her, but he really couldn't seem to give a damn. He was a freaking good kisser – Monica's words. Well, partly.
They both froze when they heard the flat's door close and suddenly pulled away, Chandler's head bumping against Monica's closet.
"Perfect!" she whispered, opening one door and shoving Chandler in it, without giving him time to think. "Rach!" Monica quickly exclaimed, leaving her bedroom to check on her friend that had just entered.
When Joey came in next, she pursed her lips, wondering if they couldn't have just pretended that she had been showing something to Chandler. But hiding him in the closet had sounded more logical on the moment. She just hoped Chandler wouldn't be mad at her. She could hardly sneak him out of her own bedroom, and their two friends could be here for a while, especially if... Phoebe or Ross came in, Monica thought just as Phoebe entered. Monica offered to go down in Central Perk after long minutes, and managed to excuse herself to her bedroom for a couple of minutes.
"I've been in here for hours!" Chandler whispered angrily when she opened the closet.
"Hours? It's not even been half an hour," she frowned.
"It felt like hours!"
"Can you hide two more minutes? Just get out when we leave."
"What? I'm not spending any more time in there. Mr. Pants is really mean to me."
"Have you tried talking to Mrs. Shirt instead?" She rolled her eyes. "Okay, I'll make it up to you. With sex," she said quickly, gesturing vaguely in the air without really knowing why.
"Okay!" Chandler said and ridiculously jumped, happy, then silently got back into the closet, obviously satisfied. "Oh," he whispered and popped his head out to kiss Monica.
"Are you ready yet?" Rachel called from the living-room.
Monica couldn't contain a happy smile, but shoved Chandler back into the closet and joined her friends waiting for her.
