AN So... I got the comments that it should continue, many many thanks! I wasn't exactly sure how was going to make it continue though because honestly, it was really just a one shot. Anyway, it took me a while, and I'm sorry for that but I appreciate your patience! Again, I don't think I'm going to continue after this chapter but I think that's ok because it doesn't really need continuing... other than for the sake of porn lol Speaking of which...this chapter is... Well SUPER M rated, more than smut... it's really just flat out porn. I started to get a little deeper into Mordred and I might wrap it up with a bit of another chapter or another story but I'm not sure yet. I'm really falling in love with Mordred though and wanting to explore him more. So if you like this and like the way I'm writing Mordred, then you will probably be happy to know that I'm starting to work on a canon Mordred/Merlin fic. He's an incredibly dark, intense, and thoroughly complex character that I really would like to work with.

Anyway, hope you enjoy this in all it's smuttiness!

Also, no idea how to create a line break this like I've seen in some writing, but this is the line break

It was painful, it was physically painful to hold Merlin this close to him. Mordred looked down at the man in his arms, the pure, innocent man that lay sleeping with his head on his chest. He ran his fingers through his hair, staring at Merlin's perfect beauty and fighting the sickness that was coming over him. Merlin was a good man, a pure, loving man and Mordred couldn't help but feel like he had tainted him somehow. When Merlin looked at him, when he saw who he was, Mordred wanted to scream, to tell him not to look at him, to not see but instead he was lost, helplessly staring back and desperately trying to figure out why he was still here.

He clenched his teeth tightly and drew in a deep breath. He was not a bad person, he told himself over and over. There was no evil inside of him, he wasn't a monster. He closed his eyes, chanting the Romanian words over and over in his mind so strongly that his lips moved with the words.

Eu nu sunt un monstru, he whispered over and over, pushing away the memories, the darkness. He clung to Merlin, to Merlin's light and his warmth.

Merlin stirred, there was a slight tugging on his head and he could hear whispering. Slowly, he opened his eyes and the room came into view. Mordred's room, he thought as he looked at the walls, cloaked in the shadows of night. He noticed then that Mordred was whispering and he listened, trying to make out the muttering.

"Eu nu sunt un monstru," he kept repeating and Merlin frowned, trying to make it out but unable to. Instead, he lifted his head and looked up at him, wondering if he would feel regret or shame when faced with the reality of his decision. Instead, what he saw when he looked at Mordred was pain on the other man's face. His eyes were squinted shut as he whispered the words, almost pleading with whatever god that he would be heard.

He had to protect him. There was something so beautifully broken about Mordred that it made Merlin's own heart break. He reached up and touched Mordred's cheek with his hand, making the other man jump at the sudden contact. He opened his eyes and looked down at Merlin and Merlin did the only thing he could think of to bring him comfort. He pulled his lips down to his and kissed again, pulling him into him, as if trying to absorb the other's pain and take it as his own. Why had he never noticed just how much pain Mordred had always been in?

They had sex again, several more times that night and into the morning.

"We should get to work," Mordred said as they lay tangled together. Their legs wrapped together, the blanket and sheets were scattered on the floor and Merlin was silently wondering what happened to his pillow as well.

"I don't want to go in," whispered Merlin. If he left this place, he was afraid he would never find it again, never find his way past the ice walls that surrounded Mordred.

"We could both call out sick," He proposed, kissing the top of Merlin's head and trailing his fingers down his spine.

"I'm pretty sure we would be missed considering I'm supposed to be heading up a meeting in," Merlin leaned across Mordred and grabbed the alarm clock that had been knocked over, "in an hour." He said with a heavy sigh. Mordred was silent for a while, a distant look in his eyes before he said anything.

"We should probably talk before we go in." He said at last and Merlin sat up, looking at him nervously. He let his eyes wander over him, taking in his tattooed torso and he could see dozens of deep scars that he hadn't noticed before but there were several of them scattered across his upper body.

"Probably," He muttered and finally made his way back to his face.

"You can't look at me like that and expect me to think," said Mordred with a crooked smile.

"Then you can't lay there looking like that and expect to have a conversation with me," Merlin blushed. God Mordred was worse than a drug, he was so addictive and even though Merlin's whole body hurt from passionate sex, he still wanted more. He quickly placed a kiss on his chin and then mouth. Mordred moaned into his lips and then reluctantly pulled away. He winked at him and then stood up, stretching his arms up before grabbing the sheet and wrapping it around his waist.

"Better?"

"No, cover your whole body," grinned Merlin and Mordred obediently pulled the sheet up around his shoulders and tossed the blanket to him.

"So... your boyfriend." Mordred spoke bluntly and looked at Merlin expectantly.

"My boyfriend," Merlin repeated and the happy fluffy feeling that was there moments ago went up in flames and was quickly replaced with guilt and fear. "He told me to... do this..." He said and Mordred's thin eyebrow lifted.

"He told you to let me fuck you?" He asked coldly and Merlin couldn't tell what he was thinking.

"Well, he said I should... I don't know... he has this crazy idea that we just needed to fuck and then it'd be out of my system." He tried to explain rather pathetically, looking at the blanket he was twisting in his hands.

"And is it?" Came Mordred's silky voice.

"No," he whispered and looked back at him. "I want you even more now." He said honestly. He didn't really mean to be that blunt, but the way Mordred's eyes pierced him made him feel like there was no other way to speak. He smiled at his words and a triumphant look passed over his face.

"Hmm, well isn't that unfortunate." He smirked and Merlin couldn't help but smile too.

"Yes, it really is." His smile fell away as he realized just how unfortunate it really was. "I don't know what I'm going to do Mordred." Mordred sat down across from him and took his face in his hands, cold eyes piercing his stormy blue and all hints of jesting were gone.

"Whatever you decide Emrys, I will respect that decision. No matter how much I want you or need you or want to fight for you, if you choose him, I will respectfully step aside. But you should know that I am willing to share you." He spoke honestly, his voice quiet with the truth of his words, "If you can't decide who to pick, then know that I'm offering a more... alternative option."

"You would share me with someone else?" Merlin asked, unable to keep the amusement from his voice, "really?"

"Honestly," He smiled back at him, "I might not know exactly who," although he had his suspicions, "but it doesn't matter. However you want to make it work." He smirked and Merlin shook his head. The idea of seeing Mordred and Arthur together, to have both of them ravishing him made his mouth dry and his cock twitch.

"That would be interesting," he finally agreed and Mordred grinned in satisfaction.

"You should dress," said Mordred finally.

Surprisingly, work remained the same and there was no awkwardness between Merlin and Mordred at work. There was still the tension and at times, Merlin had to remind himself to stop staring at Mordred's ass when he walked away but for the most part, they managed to work together without causing any problems. They agreed not to sleep together again until Merlin could talk to Arthur although neither of them was too pleased with their own maturity. They would have much rather spent the next two nights discovering more secret spots on each other's bodies than lay in bed alone and aroused.

"So... did you?" Arthur asked a couple days later after he got back from Rome. They had made love several times before they could even have a full conversation. Merlin had missed Arthur more than he thought possible and Arthur was eager to reclaim Merlin as his.

"Did I?" Merlin asked, looking up from Arthur's chest but finding the answer on his face, "oh..." he gulped and looked away. He didn't know what else to say but he knew he had to be honest, "yea... I did."

"And?" He asked and Merlin chewed his lip.

"And what?" He asked, trying to figure out what to say in answer to the question.

"Tell me about it," he said, surprising Merlin.

"What?" He looked at him and blushed a dark red, "why?" Arthur grinned as Merlin's ears turned crimson and shrugged.

"Because, I want to know," he said and Merlin smacked him.

"No, that's way too weird," he shook his head. He knew he'd have to tell Arthur but he'd never imagined he'd want to hear details. Would it hurt him?

"Did you do it here? In this bed?"

"No!" Merlin quickly said, "never," he shook his head, "at Morgana's... in the tub..." he said, the blush never leaving but he felt his cheeks grow hotter.

"Hmm," Arthur's brows rose interestedly, "sounds hot." Merlin looked at him, thoroughly confused by his reaction. "How did it happen?"

"You seriously want to know?" He asked, searching Arthur's face for any sign of doubt but only finding determination and something else, something strangely resembling lust.

"Yes Merlin, I want to know, tell me."

"He went to get wine and I went up to the tub... seemed... appropriate. I got a bath going and got in."

"Just like that?" Arthur smiled at Merlin, it was strange to picture him behaving so forward, "my, you're a brazen one." Merlin smiled cheekily and drew in a deep breath.

"He found me and..." he swallowed as the memory became more vivid and he felt himself getting hard. "And he undressed-"

"What's his body like?" Merlin couldn't believe Arthur's questions but he obediently continued.

"It's... beautiful. He's pale and has these tattoos on his ribs."

"What of?"

"I'm not sure, it's script but not in English. It's right here," Merlin ran his fingers over Arthur's ribs, tracing where Mordred's tattoo would have been. Arthur shivered.

"Go on."

"He has another tattoo on his back but... I didn't really get a good look." He said with a sly smile and bit his lip, "he's muscular but not like you, it's... more subtle but he's hard like you. And he didn't even hesitate, didn't say anything, just undressed and then came over and stood in front of him while I sat in the tub."

"Then what?"

"Arthur why do you want to know this?" Merlin asked again, he couldn't keep telling him this, it was turning him on too much to remember it and it felt way too weird.

"Because Merlin," Arthur growled, his voice lowering as he grabbed Merlin's hand and slipped it under the sheets. He wrapped Merlin's fingers around his erection and his eyes burned into him. Merlin's eyes widened in surprise, Arthur wasn't interested because of some morbid jealousy but because he was getting off on the idea of Merlin and Mordred. Merlin's whole body shivered in response.

"And he ran his fingers through my hair, gripping it tightly at the back," Merlin closed his eyes as he remembered, licking his lips and slowly massaging Arthur, "then I licked his cock." Arthur moaned and shifted under his hand.

"What's he taste like?"

"Mmm," Merlin could almost taste Mordred, the memory was so vivid, "sweet and salty. He's a vegetarian... you can taste it." He grinned.

"Then what?" Arthur prompted.

"Then he got in the water and pulled me into the middle with him and kissed me."

"What are his lips like? They look..." Arthur struggled for the right words, "delectable."

"They are... they're soft and warm, god they're so smooth." He whimpered at the memory.

"Did you take him?" Arthur asked, desperately wanting to know more details.

"No, he took me. He pushed up against the tub and just pushed right into me."

"No foreplay, no prep?" He asked, a little surprised. Normally Merlin enjoyed the teasing that was given when Arthur prepped him. Merlin just laughed an incredibly seductive sounding laugh.

"Arthur, we've had six months of foreplay," he answered honestly and he realised that was true. "He took me slow but deep. He kept hitting that spot, you know, the one that makes my toes curl?" Arthur groaned and licked his lips in anticipation.

"That's a good spot," he replied.

"Really good," Merlin was panting slightly, he couldn't believe how hot it was telling Arthur all this, "he did it until I came and then he just lifted me onto the side and started sucking me until I was hard again."

"Interesting," Arthur managed to gasp, Merlin's hand moving much hard and faster on him now.

"And then he bent me over the back," Merlin gulped, he wasn't sure how he felt about telling this next part to Arthur. It was something they'd never done and something Merlin had never even hinted at wanting although he'd had it before and thoroughly enjoyed it.

"And?" Arthur panted.

"He licked down my spine and licked my ass." Merlin said, risking a glance at Arthur who seemed to wither at his words.

"Merlin," he hissed and Merlin wondered if this was the final straw but he didn't think it was, Arthur was throbbing in his hand.

"What?"

"Call Mordred."

"What?" He blinked, pulling his hand away and sitting up. Arthur opened his eyes and looked up at Merlin.

"Seriously, call him now."

"And do what?"

"Invite him over." Arthur said rather forcefully and Merlin's stomach flipped over so many times he felt dizzy.

"Ok," he whispered and grabbed his phone.

"Merlin?" Mordred's sleepy voice answered and Merlin looked at the clock. It didn't realize it was one in the morning.

"Mordred," Merlin breathed and he could hear Mordred shift in response to his tone.

"What is it?" He asked, his voice lowering.

"I'm..." he hesitated and looked at Arthur who nodded encouragingly, "I'm at my boyfriend's and... and he wanted me to um... tell him about what happened." Merlin stumbled awkwardly over the words, too nervous to even attempt to sound sexy.

"Why?" Mordred asked and Merlin could hear the nervousness in his voice.

"He... well, he seemed to... to like the idea of us together..." he managed to get out and Mordred cleared his throat loudly on the other end. Merlin chewed his lip nervously.

"Ok," was all Mordred could manage to say.

"And... well, he... he wanted me to ask you to come over." Merlin stammered.

"And what do you want me to do Emyrs?" He asked, that silky tone making Merlin's insides shudder.

"I want you to get over here right now." He replied, surprised by the forcefulness in his own voice.

"Text me the address, I'll leave now." Mordred said and hung up. Merlin looked at the phone in his hand before sending him the address and setting the phone down.

"Well?" Arthur asked finally when Merlin didn't seem like he was going to say anything.

"He's on his way..." he whispered and suddenly burst out laughing.

"What's so funny?" Arthur asked, grinning over at Merlin.

"I can't believe you're suggesting we do this! I mean, of all the things I've thought about," Merlin laughed, "and all the filthy things I've thought, I never imagined this could ever happen."

"So you thought about it?" Arthur sat up and slipped his arm around Merlin's naked waist.

"Well... yea. Apparently you have too."

"Not until recently..." Arthur replied honestly, "I was trying to figure out exactly what it was about Mordred that you were attracted to."

"Find something you like too?" Merlin teased and Arthur brushed the hair from Merlin's forehead.

"Yes. When I was in Rome all I could think about was the two of you in this bed. I kept thinking about you taking him and what it would be like to watch that."

"That's fucking hot," Merlin grinned and kissed Arthur heatedly. Merlin had made his way onto Arthur's lap, kissing him with a new found desire when the phone rang.

"Hello?" Arthur answered. It was the doorman saying there was a gentleman here saying he was invited up. Arthur told him to send him up. "Go wait for him at the elevator. Does he even know who your boyfriend is?" He asked suddenly and Merlin shook his head.

"I don't know, I don't think so but maybe."

"Well best you be the first one he sees. Here, put these on." Arthur tossed him his briefs and Merlin slipped into them, adjusting his erection so it wasn't sticking straight out. He walked over to the elevator and leaned against the wall, waiting.

Mordred tried to calm his rapid breathing as he rode up the elevator. He had no idea what he was doing here, it definitely wasn't a good thing but the prospect of being with Merlin again was just too tempting. Of course, his boyfriend being there was not something he had imagined but Merlin was just too damn addicting to let the opportunity pass. The elevator dinged as it reached the top floor and the doors opened. Merlin stood in front of the doors, leaning against the wall in nothing but a pair of charcoal briefs. Mordred drank in the sight, noticing his erection and the recent bruising that Mordred had not left. He smiled as he saw Merlin's red lips, clearly still flushed from a long kissing session.

"Emyrs," he whispered before Merlin was on him. His hands felt like they were everywhere, trying to get at Mordred as his lips pulled Mordred's in. He opened his mouth eagerly, twisting his tongue with Merlin's and moaning as Merlin's warmth reached the very core of his being.

"Come in," Merlin finally breathed and slipped his hand into Mordred's. He led him down a hallway, Mordred could see the light from the bedroom still on but he was pleasantly surprised at who he saw laying naked on the bed.

Arthur lay sprawled out on his back, his hand lazily trailing over his abs, the sheets a tangled mess around him and his blonde hair was a sweaty mess. Obviously they hadn't left the bed in some time and Mordred could smell the lingering scent of their activities. He was surprised by how much it aroused him.

"Arthur," he said, nodding to him and Arthur looked at him with a completely different look than he ever thought he'd see him give him.

"Mordred," he said. He liked the way he said his name. Mordred looked back to Merlin who was looking between the two, looking at Arthur for instructions. It was interesting to see Emyrs so submissive. Despite the fact that it had been Mordred taking Merlin, he never felt in control, it was always up to Merlin how far they went, what they did. He liked it that way, it was a way he felt he could safely submit. Arthur gave Merlin a look that Mordred couldn't really read but was obviously the answer to whatever question he had silently asked him.

Merlin shoved Mordred hard against the wall, his mouth taking his again and Mordred melted into Merlin. It was different, Merlin was much more commanding, and his hands tore at Mordred's clothes. He ripped off his jacket and nearly ripped his shirt attempting to remove it from him. Mordred shook with Merlin's need for him, it was so incredibly powerful and he could feel in his touch the desperate longing. He craved him just as much as Mordred craved him. Mordred undid his own pants, kicking them aside as he grabbed Merlin's hips and hoisted him up on the wall. He growled and bit into his neck, directly over a recent love bite Arthur had give him and the idea that Arthur's mouth had been there only hours before made him want it all the more. Merlin's nails dug into his back and he could feel the cold air on the raw streaks that he left behind him. Merlin pushed against him, his feet hitting the floor and he pushed Mordred backwards towards the bed. Mordred smiled and grabbed Merlin's throat and in one quick motion, Merlin was sitting on the edge of the bed and Mordred stood over him. He looked over at Arthur who had been watching with fascination. He smiled at him, this was what they had been silently battling over for the past six months, each fighting each other in some way. Mordred pushed Merlin back into Arthur's arms and Arthur pulled Merlin up onto his knees. Arthur's arms slipped around him and he ran them over his chest and Merlin moaned, leaning into him. Mordred crawled onto the bed and stood on his knees in front of Merlin. He slipped his hand around his neck again and pulled him to him, kissing him greedily while he kept his eyes open, watching Arthur. He moaned loudly into Merlin's mouth, letting his hands move down his body and over Arthur's as the two men touched and explored Merlin's body. Merlin was in heaven, he had decided that the moment he felt both of their hands on him. He was going insane, having them both tease him and tear at him in such a slow way. He was completely oblivious to the battle they were fighting over him.

Arthur yanked Merlin's head away from Mordred by his hear, causing Merlin to yelp but he didn't get the chance to protest and Arthur crushed his lips to him. He could taste Mordred on him and pressed his cock against Merlin's back, making him moan. Mordred kissed Merlin's cheeck, watching Arthur kiss him. Arthur's eyes never left Mordred and he couldn't help himself from grinning. It was amusing and incredibly sexy, whatever it was that was happening between them. Arthur's hand snaked up around Merlin's throat and jaw, holding his head to him as he continued to kiss him, removing all traces of Mordred. When he finally released him, Merlin was gasping for air and Arthur's mouth kissed down his neck and shoulder. He bit into his shoulder and sucked hard, leaving an angry welt as he continued to kiss down his back. Mordred accepted the challenge and took the welt into his mouth, tasting Arthur and Merlin at the same time and finding that he really enjoyed it. Arthur was salty whereas Merlin was sweet. Merlin was panting and gasping for air as the two of them kissed all over him, he was absolutely losing his mind. Arthur's hands moved over Merlin's hips and wrapping around his cock, enjoying the feel of Mordred's erection brushing against the back of his hand. Mordred slipped his hands around Merlin's back and grabbed his arse tightly giving it a good squeeze that made Merlin whimper. Without hesitating, Mordred reached further and grabbed Arthur's cock, pulling it against Merlin's ass and guiding it in. Merlin and Arthur both moaned in pleasure and Mordred smirked, dripping with pleasure as he watched Arthur take Merlin. His mind was racing as he watched; it was beautiful and so painfully pure love between the two of them. The pain of watching it mixed with the pleasure and Mordred's need to be closer to it overwhelmed him. He desperately needed to touch that connection, to feel the fire that burned between the two of them so powerfully with no regard to himself; he didn't care how badly he would burn in the process. He leaned over Merlin's shoulder and pressed his lips against Arthur's. Arthur's free hand reached up and gripped Mordred's hair as they smashed Merlin's body between the two of them as if he was just another barrier keeping them from each other. Their kiss was hard and painful, teeth biting as they raged against each other. Neither man would ever be able to explain the force pushing them together. It was a kiss full of hatred and lust and need and so clearly the opposite of Arthur and Merlin's kisses. Merlin was grabbing Mordred's cock, pumping him hard against himself as Arthur thrust in and out of him. He was trying to watch the two kiss but it was too awkward of an angle to get a good look. And then Merlin had an idea and he bucked against Arthur and pushed Mordred away. The two looked at him, stunned as they were pulled out of whatever trance they had just been in. Merlin grinned at the both of them, he was so incredibly turned on and something in him needed to take control of the situation. He winked at Arthur and then pushed Mordred onto his back. He slid his hands up his legs, licking his way up his shaft and circling the head. He flicked the tip of his tongue against the tip, licking away the drops of pre-cum. Mordred watched him with fascination and Merlin looked up at him. They were talking again in that special language of theirs and neither of them cared if Arthur could understand or not. In that one look, Mordred completely submitted to Merlin, allowing him whatever he wanted. He would do anything, give him anything, just to please him. He would let him take anything he wanted. God he wanted Merlin to take it all, he cried out as Merlin sucked him hard, he needed him to take the cold away.

Arthur watched Merlin suck Mordred and he stroked himself while he watched. There was something so unique about the way they interacted. Arthur had obviously watched porn before, had even had a couple threesomes in the past but this was so completely different. There was something between Mordred and Merlin that he didn't understand, could never understand but he was not jealous of it. He knew that Merlin was giving Mordred something he desperately needed, something only Merlin could give him and Arthur was fascinated by it. He was so exposed, so vulnerable beneath Merlin's command and it was so remarkably different than how he always was. So controlled, so distant and cold, but here, with Merlin's mouth around his cock, he was reduced to nothing. Before Mordred could release himself into Merlin's mouth, Merlin pulled away and grabbed the bottle of lube that had been left in the bed from earlier. He knelt between Mordred's legs as he opened the bottle, his eyes locked on Mordred's and the look in Mordred's eyes was not missed on Merlin. He was afraid, genuinely afraid and Merlin smiled the smallest of smiles that just barely tucked at the corners of his lips. Mordred caught the subtle movement however and it said more than anything either of them could have said. It said that it would be ok, that Merlin would take care of him, that Merlin would never allow him to be hurt again. And as Merlin prepared his entrance, he knew without a shadow of doubt that Mordred was his. No one would ever have him this way, no one would ever be allowed to be inside of him just as no one else was ever allowed in Mordred's heart.

The pain was blinding at first, so familiar and so horrid that it took everything Mordred's power to not scream and push Merlin away. Nightmares threatened at the back of his mind like black smoke, deadly tendrils reaching out in an attempt to snare but like a gust of wind, Merlin's mouth was on Mordred's. His lips gently, lovingly caressing his own and the fear disappeared with the pain as Merlin's warmth enveloped him and began to fill him with pleasure. A few seconds later, he was moaning with pleasure and desperately trying to pull more of Merlin into him both in his mouth and ass. Merlin slowly pulled his hips back and then slid back inside and Mordred gasped loudly as the pleasure shot all the way through to his toes. He finally dared to open his eyes again and saw Merlin laying over him, his arms on either side of Mordred's head holding him up as he slowly moved inside of him. His lips were parted just slightly as small, incredible gasps escaped and his eyelids fluttered closed. Again, Mordred was struck with just how beautiful Merlin was and he arched his back to him.

He remembered suddenly that Arthur was still there and he looked over Merlin's shoulder to see Arthur kneeling behind Merlin. Mordred's eyes trailed down Arthur's body and noticed that he had one hand wrapped around his own cock while his other hand was busy teasing Merlin's ass. He smiled; the site was incredibly arousing and made Mordred moan just a little louder. Arthur could have Merlin as long as Merlin could have Mordred he thought and as if Arthur had tuned into his thoughts as well, he watched as Arthur brought his hips to Merlin's and pushed into him. It caused a chain reaction. Merlin's hips automatically shot forward which caused him to push even deeper into Mordred which caused a pleasured scream to burst from his lungs. It took a little coordinating and a few awkward thrusts before they found a rhythm that all three men gasping, panting and screaming in joined ecstasy.

It didn't take long before Mordred felt Merlin come, filling his ass with his seed which was an amazingly wet and hot sensation that caused Mordred to come. Merlin was shuddering, his muscles tensed as he was lost in his orgasm and with two thrusts, Arthur was coming inside of Merlin. They rolled their hips, pumping ever last ounce of pleasure before they collapsed over a gasping Mordred.
