They arrived at his room and went through the door, shutting and locking it behind them.
"Ye gods, I thought we'd never get out of there..." said Arthur as he pinned Merlin to the door with a kiss.
"Been wanting...you...all day..." Merlin panted, sliding his tongue into Arthur's mouth to explore.
"Mm," said Arthur, pulling himself away with a groan and looking Merlin up and down. "Lose the clothes."
Merlin grinned crookedly and divested himself of shirt and pants, but left the neckerchief on. He knew Arthur's kinks by now.
Arthur grinned back.
"Oh, yes. That'll do fine," he said. "Now me."
Instead of doing what he was told, however, Merlin threw himself at Arthur, kissing him deep and hard until their teeth clicked together. His legs locked around Arthur's waist as he rubbed himself shamelessly against the prince's torso.
"Oh...Merlin...love your...disobedience...unh!" Arthur said as Merlin attacked the side of his neck with nips and bites.
Merlin chuckled against his skin. "No matter how many times a day you complain about it, lover..."
Arthur couldn't answer-Merlin had moved his hands to the edge of his shirt and was lifting it up.
"Agh! Cold hands!"
"Sorry."
"No matter," said Arthur slyly. "I'll warm them up."
"You can," said Merlin, tweaking Arthur's nipples and making him squeak in an unprince-like way, "But first- clothes off."
"You do it," said Arthur, placing his hands on his hips.
Merlin responded by pushing Arthur backwards onto the bed and crawling on top of him.
Merlin stripped his prince slowly, with kisses applied to his stomach and chest as his red shirt went up and over his head. He stripped his boots from his feet and kissed the soles as Arthur trembled and bit his lip, trying to control himself a little longer.
"Oh, Merlin...Merlin..."
Merlin moved up and with shaking hands attempted to undo Arthur's breeches. His fingers brushed Arthur's cock repeatedly and left the prince nearly flying off the bed in ecstasy.
Finally he managed it, and Arthur soon lay there, panting heavily beneath Merlin.
Merlin sat back on his thighs for a minute, just looking at Arthur. Finally growing impatient with his lover, Arthur said, "What?"
"You're beautiful, you know," said Merlin, gazing steadily at Arthur.
"I'm WHAT?" said Arthur, sitting up to look into Merlin's eyes more carefully.
"You are beautiful. I find you caring and sweet and handsome and really all around just about the most..."
Arthur placed a finger on Merlin's lips and followed it with his own lips. After a moment he pulled back and said, "Thanks."
"I was going to finish that with arrogant prat but you took the words right out of my mouth."
Arthur snorted.
"Well I WAS going to say you weren't an idiot, but I'm more interested in this..." and he grasped Merlin's cock and began stroking it with strong and gentle hands.
"Agh! Arthur!" said Merlin as he nearly fell off the bed in pleasure.
"That's more like it."
They didn't speak again for awhile, not until Arthur was leaned over his servant with his cock deep inside Merlin's body. He was thrusting at a slow and steady pace, slamming deep right where Merlin wanted him. Grunts, groans, and gasps of pleasure issued from both men.
Arthur came first, spending himself with a shout that almost took the castle down. He was vaguely aware of Merlin's eyes going wide and gold beneath him and a warm sticky liquid hitting him in the stomach as they collapsed in a sated and sweaty heap.
Later, when they were curled around each other in bed, Arthur whispered in his sleeping lover's ear, just above that red neckerchief he just couldn't get enough of, all the ways that he was beautiful, too.
