A/N: This is a continuation of a short mostly PWP ficlet that was written for the Merlin Frottage Fest over on Live Journal. Thanks so much for all the reviews/favourites/alerts. It's great to know that people are appreciating my random outpourings. These boys are just so much fun to play with.

Please start with Chapter 1 if you've not read the rest

Merlin had always secretly loved watching the Prince when he was training. Arthur was in his element on the field, a natural fighter and leader of men. Merlin never found him more attractive than when he was wielding a sword, armour gleaming, his voice ringing out confidently as he issued commands and gave instruction. Today the pleasant tingle in Merlin's arse added an extra frisson to the situation as he stood on the sidelines watching his master and recalled the events of the morning. Merlin suppressed a shiver and a grin as he remembered Arthur's hard strong body moving naked over him in the stables. He hoped that the Prince would want a repeat sometime soon, he was getting hard already just thinking about it.

The knights were taking it in turns to challenge each other. Arthur was currently fighting with Sir Leon, blocking and parrying every cut and thrust of his sword. He seemed on good form today, Merlin noted, there was an extra energy and power to his movements. Merlin indulged himself in a small secret smile. Morning sex obviously agreed with his master, it certainly wasn't hindering his performance on the training field.

The pleasurable drift of Merlin's thoughts was interrupted as Arthur signalled to the knights to take a break. The sun was high in the sky now and it was getting hot. The knights pulled off their armour and stripped down to shirts that were already damp with sweat as Merlin poured water out for them to drink. Gwaine approached, stripping off his shirt as well as his armour. Merlin's eyes slid over his slim but muscular frame, unable to resist the temptation to check him out. Gwaine was a handsome devil and was fully aware of his own attractiveness. It was common knowledge that he swung both ways and liked to spread his favours around. He met Merlin's eyes with a broad grin as Merlin handed him a cup of water.

"Like what you see Merlin?" he smirked as he took the water and clapped Merlin on the shoulder, his hand lingering there just a fraction longer than necessary. Merlin flushed and looked away.

"Stop harassing my servant, you oaf," Arthur's voice was light but there was an angry glint in his blue eyes and his jaw was set tight. Although his words were directed at Gwaine it was Merlin that he looked at. Merlin felt a small thrill at his obvious jealousy.

"Sorry Princess," Gwaine's voice was unrepentant as he moved away. "You know I can't resist a pretty face... or a pretty arse." He grinned at Merlin and raised his eyebrows suggestively, then sauntered off to sprawl on the grass in the sunshine, chatting with the other knights.

Arthur approached, still glaring at Merlin and held out a hand to take the water that Merlin was pouring. He snatched it and stalked away without a word.

After a short break the knights were back up and training. As a concession to the heat of the day, Arthur had decided that they would leave off their armour and practise hand to hand combat for the latter part of the session. They paired up to challenge each other and Arthur ended up with Gwaine as his partner. Arthur stripped off so both men were shirtless, their skin gleaming in the sunlight under a slight sheen of sweat. Merlin watched as they squared off, circling each other warily. The Prince still looked tense and angry, and Gwaine was trying to appear relaxed but there was a watchful look in his eyes. This should be interesting, Merlin thought. He felt his cock growing hard, turned on by the sight of them, and by Arthur's sudden surprising possessiveness.

Suddenly Gwaine lunged for Arthur, trying to take him by surprise but the larger man was ready for him. Despite his size, Arthur moved with amazing agility and dodged Gwaine easily, using his foot to trip him up. But Gwaine managed to roll away and scramble back to his feet before Arthur could pin him down. There was another pause then Gwaine struck again. As before, the Prince was ready and avoided being knocked down. The match continued with neither man quite able to get the upper hand. Arthur had the advantage of size and strength but Gwaine was fast and cunning, never going for the obvious moves.

They were getting increasingly sweaty with the exertion and both men were beginning to breathe heavily. Gwaine pushed a lock of damp, dark hair out of his eyes and caught Merlin looking at him. He grinned and winked at him. Arthur's eyes flickered as he realised who the wink was aimed at, and before Gwaine could get his attention back on his opponent the Prince exploded into motion. He wrapped his arms around Gwaine's waist, and the power and weight behind the movement took the slighter man down with Arthur pinning him to the ground. Despite Gwaine's best efforts he was unable to twist free and finally conceded defeat. Arthur held him down for a few seconds longer; glaring at him with narrowed eyes, then picked himself up and swept over to where Merlin was waiting with more water.

"Well done Sire," Merlin met his clear blue gaze. Arthur nodded curtly and took the proffered water. He downed half of it immediately and poured the rest over his head, shaking the water out of his hair like a dog coming out of a river. Merlin's eyes were drawn to the drops as they trickled down the hard planes of Arthur's chest and abdomen. He dragged his eyes back up and realised that Arthur was watching him. His cheeks flushed with heat at being caught ogling so obviously.

"Right," Arthur's voice rang out clearly. "That's it for today, well done, you've all worked hard." Then as the knights and other servants started to gather their weapons and belongings, he leaned back towards Merlin and spoke quietly. "Be in my chambers in twenty minutes." Merlin's heart thudded in his chest as he nodded, then hurried off to get his remaining duties done as quickly as possible.

XOXOXOX

When Merlin got back to Arthur's room the Prince was there already, standing looking out of the window, arms folded. He was still shirtless, and Merlin admired the strong curves of the muscles in his back and the broad expanse of his shoulders. He didn't turn as Merlin entered.

"Sire?" Merlin spoke uncertainly, trying to gauge the Prince's mood. Arthur paused for a moment before slowly turning to face him. There was still anger in his eyes but there was want and need too. Merlin felt himself harden again. All he could think about was Arthur naked and thrusting into him and the taste of Arthur's cock in his mouth. He waited, passive as Arthur approached.

"What the fuck did you think you were doing, flirting with Gwaine?" Merlin was taken by surprise at the barely controlled fury in Arthur's voice as he towered over Merlin.

"I was hardly flirting, you know what Gwaine's like..." he began in an attempt to defend himself.

"Yes, I know exactly what he's like which is why I want you to stay away from him."

"Arthur... are you jealous?" Merlin wanted to hear him admit it.

"What if I am?" Arthur flushed a little but rallied quickly. "You're my servant; he has no right to be... messing around with you." He sounded indignant.

"So what are you saying? That you're the only one who's allowed to mess around with me, as you so delicately put it?" Merlin was starting to rather enjoy this exchange.

"I don't know!" Arthur groaned in exasperation then blurted out "God, Merlin! I just know I wanted to bloody kill him when he touched you earlier." He turned away again and tore at his hair in frustration. Merlin took pity on him.

"Arthur," he said quietly. Then repeated his name until the Prince turned his head to meet his eyes again. "Arthur... I don't want Gwaine. The only person I'm interested in messing around with..." his lips quirked, "is you." There was a silence as their eyes locked.

Suddenly in a blur of movement Merlin found himself swept up and unceremoniously dumped on the royal bed. Arthur's lips were on his, his tongue pushing insistently at Merlin's lips until he gained entry. His hands tore at Merlin's clothes between fierce kisses, pulling and almost ripping them until he had stripped him bare. Merlin wriggled to help and gasped as Arthur's mouth moved down, licking and nipping at his neck until he reached a point below his ear and bit down, sucking hard, marking Merlin with his teeth. Merlin moaned, ridiculously aroused, his whole body tingling with need.

Arthur worked his way down Merlin's body with his tongue and teeth causing him to writhe and mutter incoherent sounds of yes and more and please as Arthur nibbled on his bony hips, his tongue tantalisingly close to Merlin's throbbing erection.

"Only I can do this to you Merlin," Arthur murmured into his skin, his breath hot and delicious. "Only I can make you feel like this."

"Yes... yes you Sire, only you," Merlin's voice was keening now, he was wound up and desperate for release. He groaned and arched up wantonly seeking contact, as Arthur's hot breath teased the head of his cock.

"Oh... yes... please. I need to feel your mouth on me," he begged, as Arthur hesitated just for a moment. Merlin looked down and met the intense blue gaze of the Prince, as he looked up through long lashes at his servant and licked his lips.

"Only me," he whispered, as he finally parted his lips and drew Merlin's cock into the warm heat of his mouth.

Merlin let out a strangled cry as his hips bucked up uncontrollably, Arthur held him down with strong hands and he fought to control his urge to come. The feeling of Arthur's lips and tongue around him was indescribably wonderful, and he wanted to enjoy it for a little longer.

Arthur's mouth moved insistently, taking Merlin deep and sucking back up with a swirl of his tongue at the tip. He was sloppy and obviously inexperienced, occasionally grazing Merlin with his teeth but to Merlin it was the best thing he had ever felt. Heat bloomed in his belly and spread in a flush up his chest and into his cheeks as he entwined his fingers in Arthur's blonde hair and pulled gently in warning.

"I'm going to... Arthur... I can't..." he gasped, unable to form a coherent sentence.

Arthur carried on determinedly and Merlin finally cried out and gave himself up to the sensations flooding through him. His muscles clenched and his hips strained against the grip of Arthur's hands as his cock twitched and pulsed out his release deep into the Prince's throat. He swallowed around him and continued sucking until Merlin moaned and reached down to pull his lips away from his now over-sensitive cock.

Arthur raised his head and grinned, looking pleased with himself. This was not an unusual expression for the Prince but the situation was new. Merlin rather liked it. He smiled back goofily and reached for Arthur, pulling him up for a kiss. He could taste the bitter salt of his come on the other man's tongue and he moaned into Arthur's mouth, reaching for the ties on his trousers.

"You have too many clothes still on," he said huskily between kisses.

Arthur hummed in agreement and helped push off his trousers, then moved to straddle Merlin his cock straining out from the nest of brown curls. The Prince took his cock in his fist and started to stroke himself in steady firm movements.

Merlin watched entranced, the sight of Arthur pleasuring himself went straight to his own cock which began to harden again between them. Merlin reached to help him, caressing his balls and scraping his fingernails along Arthur's thighs, causing him to bite his lip and groan. Merlin touched his finger to the tip of the Prince's cock and caught the wet stickiness there, then reached back behind his balls to gently probe his arsehole. Arthur's eyes flew open and he gasped.

"Fuck! Merlin... oh God!"

Merlin wriggled his finger and pushed gently into the tight heat and thrust it in and out, curling and twisting. Arthur tensed and sped up the movement of his hand on his cock.

"Oh fuck... yes... FUCK!" Merlin felt him contract around his finger and he came, shooting thick white dribbles onto Merlin's chest. "You're mine Merlin, mine," Arthur gasped out still fisting his cock, forcing out the last drops.

Then he removed his hand and swirled it in the viscous liquid now painting Merlin's torso. Arthur's brow furrowed in concentration as his finger traced a sticky path. Merlin watched and quirked an eyebrow as the Prince sat back and eyed him, lips twitching.

"Just marking you with my royal seal, Merlin," his mouth curled into a self-satisfied grin. "So that you don't forget that you belong to me and only me."

"Hah! You wish," Merlin rolled his eyes and tried to look affronted. He was damned if he was going to admit that that secretly that arrangement suited him just fine.
