All I want for Christmas... (ES Secret Santa)

Christmas was one heck of an event for the Team.
Everyone pitched in to decorate headquaters with paper snowflakes and strings of tinsel and everything inbetween, turning the usually strict and businesslike building into a holiday wonderland.
Fake snow frosted the windows and stairs. Tiny Christmas trees, hung with miniature baubles, adopted every available surface as their own. Here and there a spec of silver or a twinkle of gold brightened the floors where a stray piece of glitter had fallen.
The way it made Carlos smile was enough to melt Roy's hardened heart.
They stood together in the foyer, taking in the enormity of the team's collective festive efforts.
Carlos braced his hands on his hips.
"I knew this was a fantastic idea," he declared proudly. Roy snorted.
"Oh please, the Team came up with it together."
"Yeah but I was the one who brought it up in the first place," Carlos pointed out, not untruthfully. "And the trees were my idea."
"I wish Batman had let us have a big tree rather than lots of smaller ones," Roy grumbled, crossing his arms.
"It's not all about size, Roy."
The archer turned a raised eyebrow on his friend, who twitched his lips in a cocky grin and winked. Roy was surprised to feel himself blush.
Seemingly unphased, Carlos slung an arm around Roy's shoulders and led him through to the common room, where the rest of the Team was wrapping presents. They paused in the doorway.
Artemis and M'gann were sitting amidst a pile of paper and tape on the floor, trying to wrestle something into the red-and-gold wrapping. Jaime and Bart were attempting to tie ribbon bows under Karen's patient instruction. Garfield looked up from his relaxed position on the lounge, and his eyes brightened.
"Ooh look who's under the mistletoe!" he crowed.
All eyes in the room turned to the young men, who simultaneously looked up.
Taped informally to the lintel of the doorframe was a sprig of leafy greenery.
Roy went as red as his alias suggested, and even Carlos pinked.
"Now I wonder who could've put that there," Garfield drawled with mock innocence, rubbing his chin thoughtfully.
"You little monkey!" Roy growled, moving to approach the shapeshifter. Carlos grabbed his arm.
"Roy, it's okay."
Carlos could feel Roy's tension, could almost hear his panicked heartbeat. His hand trailed down to catch in Roy's fingers, which were a little sweaty.
His own heart took a turn. Was Roy afraid? Goodness knew he himself was. But in a good way.
Roy swallowed past the lump in his throat and turned back to Carlos.
"You're... okay with this?" he muttered, avoiding Carlos' eyes.
"If you are, then yes."
There was a long pause, and at the end of it, Roy gave the tiniest of nods.
"So..." Carlos shuffled a half-step closer to the archer. "Can I - Can I kiss you now?"
Roys fingers twitched around Carlos' hand, his chest expanded as he drew a long breath and let it out.
"Yes."
Tension wound tight in Carlos' chest as he leaned forward and pressed his lips to Roy's.
But in an instant it vanished, a spring uncoiled and he felt everything melt. Roy must have felt the same because he suddenly relaxed, eyes closing and heart slowing to a steady thud-thump.
The Team were either too stunned or too excited to make much noise, but for that, Roy was glad. Any interruption to their moment was unthinkable.
And though headquaters was gloriously Christmassy, and there would be presents the next morning, and carols later that night, the only thing they wanted that Christmas was that moment with each other.
