This idea just randomly came to me in the middle of Maths, and I couldn't get it out of my head, so I wrote it down. I rated it to be safe; I am not sure if it was T or M.

Beneath the Red Scarf

Merlin groaned as Arthur kissed him, his hands twisting in Arthur's dirty blonde hair. He was pressed up against a wall in the castle, and it was nearing midnight. The pale moonlight shone on the boys, highlighting their writing bodies.

"Arthur…. Arthur, someone might hear." Merlin managed to get out, before his mouth was claimed again. Arthur didn't reply, but moved his lips lower, from Merlin's lips to his cheek, his strong jawbone, down to his neck. Merlin gasped as Arthur began to lick and suck at the sensitive skin there, rolling his head back as the sensations rushed through him. Arthur focused his mind entirely on the pale skin. He wanted to mark his manservant, to show that Merlin was his, that he was Merlin's. He was so caught up in his desire, that he nearly didn't hear the heavy footfalls heading towards him.

Arthur pulled away, eliciting a disappointed moan from Merlin. He pressed his finger to Merlin's swollen lips to silence him.

"Shhh…. I can hear a guard." He whispered softly, his mouth right next to Merlin's ear. Merlin nodded, and moved away from him.

"See you tomorrow, Merlin." Arthur murmured, brushing his lips against Merlin's in a chaste kiss. And then he was gone, striding almost silently through the palace that would one day be his. Merlin smiled slightly, and headed back to his chamber.

Merlin wasn't sure what time it was when he had finally fallen asleep. He knew that it had been late. He had lain awake for at least an hour, thoughts of Arthur running through his mind. When he had finally drifted off, he had dreamed of him. Merlin sighed as he realised that he had to get up; he had to leave the warm bed. Swinging his legs over the side of the bed, he stood up and swiftly dressed himself. Yawning slightly, he made his way down to the main chamber. Gaius was still asleep, snoring loudly as he always did. Merlin grinned, and grabbed the bucket of water that was sat upon the table. He splashed his face, gasping at how cold the water was. He sat it back down, and waited for the ripples to still. Royalty like Arthur could afford mirrors to look at themselves; everybody else had to make do with water, like Merlin did. As his face came into view, Merlin moaned slightly.

There, on his neck, was a huge love bite, coloured purple and blue. Merlin sighed; he'd have to wear his red scarf again. Gaius stirred slightly in his sleep, causing Merlin to leg it back to his room; the last thing he needed was a lecture from Gaius about "being careful".

When Merlin entered Prince Arthur's chambers twenty minutes later, the love bite was safely hidden away. Arthur was lounging on his bed, his shirt off, grinning sexily at Merlin. Merlin gulped slightly. Arthur stood up, and made his way over to Merlin. Closing the door, he pressed himself against his manservant, and removed Merlin's scarf. Gently and softly, he kissed to bruise on Merlin's neck.

"Mine." Arthur growled possessively.

"Always." Merlin agreed.
