Disclaimer: I do not own Merlin or any of the characters. If I did Merlin/Arthur would be canon (well more canon than it totally already is anyway…)

"Merlin! Heavens above, what took you so long?" Arthur cried as his gangly servant finally strolled through the door.
"I was doing your laundry," Merlin protested, cut off with surprise as Arthur whizzed past him to close and bolt the door. "What are you doing?"
"What does it look like I'm doing, Merlin?"
"It looks like you're hiding from spies," Merlin observed as Arthur dashed across the room to yank the curtains across, plunging the room into dimness.
"I thought you'd never get back," Arthur said, and striding across the room, he cut off Merlin's response with his mouth, hard and firm on Merlin's.
"Arthur, it's," Merlin began as soon as Arthur pulled back. "Oh. I see what you were doing there," he gestured understandingly as the reason for Arthur's mad dashing about set in.
Arthur nodded with the kind of patronising smile he often returned to Merlin's slowness. "Yes. Well done. Now please tell me you're coming to bed?" This smile, full of kindness instead rendered Merlin to a speechless nod.
Arthur fell to it with no hesitation, as soon as they were on the bed, yanking Merlin's scarf off so impatiently he almost gagged the boy. "Arthur! Arthur, slow down, you're hurting me," Merlin protested, shifting uncomfortably on the bed.
"Sorry," he heard Arthur murmur, and then the prince caught his lips and Merlin was lost in a torrent of sensuous caresses. Desire jittered down his body as they shifted into an easier rhythm and he gazed blearily at Arthur as he pulled back, severing the touch. The prince slid out of his blue jacket and Merlin watched, already picturing him naked. Awkwardly he shimmied out of his own, and Arthur, having already discarded his shirt, had Merlin raise his arms to remove his as well.
He felt that illicit deliciousness swirl through his body again at Arthur's hands on his waist, gradually easing down his trousers, and smiled through a gasp. "H-Have you been planning this all afternoon?"
"Uh-huh," Arthur nodded breathlessly, and Merlin bit his lip as his body was completely exposed. He vaguely heard Arthur's impatient growl as the man tore off his own trousers and whimpered soundlessly.
"Get under the covers," Arthur commanded, yanking back the red velvet sheets and Merlin didn't hesitate. The feel of the material against his skin was sinfully good and combined with Arthur's bare skin pressed to his, he was in heaven.
He swallowed as his eyes met Arthur's and desire lingered in the air, as palpable now as the physical proof of his own arousal, pressing into Arthur's thigh. He bit his lip.
Arthur swallowed. "Merlin." Diving in, he invaded Merlin's lips until Merlin had to break away to gasp. Undeterred, Arthur moved to Merlin's bare neck, each assault deeper and more intense until Merlin had to push him away, quivering.
"Sorry, got carried away," Arthur murmured. "Turn around."
Flushed with pleasure, Merlin nodded, and awkwardly rolled over, grasping onto one of Arthur's long cushions and inwardly wincing at the feel of the material grazing against his erection.
"Do you want me to prepare you?"
Merlin shook his head. "No, you don't need to," he said, aware that neither of them wanted to wait any longer.
Arthur nodded behind him. "I'll be gentle."
Merlin shifted a little, parting his legs further, and readied himself. A moment later he felt Arthur against him, hesitantly easing in. He closed his eyes, feeling the breath escape him at the penetration. He clenched around him, trying to become accustomed to the feel again, and heard Arthur moan behind him. Lying on top of the sweat covered boy and placing his arms around him, around the cushion he held; so driving Merlin further against it, Arthur began to buck, slowly, deliberately into Merlin.
It didn't take long for sensation to begin consuming Merlin and soon the two were breathlessly gasping in synchronicity.
"Arthur," Merlin cried, his breath pushing out of him onto the cushion. "Jack me off." He found Arthur's hand and guided it to his pulsing cock. Arthur began to pump it desperately until Merlin arched and cried out, white streams of liquid shooting forth.
"Merlin, Merlin, Merlin," Arthur chanted in a whisper, thrusting into him with slow deliberate strokes, and Merlin managed a long, furious muscle contraction around Arthur, causing the blonde to emit a throaty cry before releasing and slumping onto his lover's body.
When he comes to, we're doing that again, Arthur thought as he gazed at Merlin's now sleeping face, still flushed pink with their activity.
