Merlin let Tristan kiss him, it wasn't the first time he had kissed Tristan over the years since he knew him they have shared a few kisses, but this one seem different it was like both of their magic was reacting to each other to the point Merlin had to pull back with a gasp his eyes turn amber as he looked at the midnight blue orbs "W…What was that?" Merlin asked, as he rubbed his arm, it felt strange like it was tingling. The younger prince smiled as he pulled back the sleeve of Merlin's arm and showed him the mark that was forming "Oh god…is that what I think it is?" Merlin whispered

"I think it is." Tristan said, he was smirking in his mind as he pulled back his sleeve and showed it to the young warlock who was blinking in shock.

The day Tristan has met Merlin he also happen to be reading up on magic on one of a few book his father had kept because of Gaius had told him that 'encase of curses or poisons it handy to keep these books for reference.' So when Tristan found out about the hidden secret stash he decide to read though them all. In one of the book he found a chapter on soul mates among magic folk it said that 'Your soul mate may not appear to you the moment you met them, your magic will decide if this person is right to be your soul mate. It could take some years before it appears.' He frowned when he read this but at the bottom of the page there is a hand written note 'giving gentle hums of your magic to the one you want will form the soul mark, don't do it to quickly or it will over load your intended senses, still may takes years but you know when it work because all it will take for the mark to form is a single kiss.' So that is what he's being doing give Merlin tastes of his magic without the poor Warlock knowing about, of course there has been time when he had to help heal Merlin and poured his magic into him but that worked in his favour to.

He looked back at Merlin and smiled brightly as he kissed him again "My Soul mate." He whispered to him, the dark haired wizard smiled back and it was the first happy smile he has seen on Merlin's face in a long while. Tristan pulled him in for a deeper kiss and Merlin warped his arms around his neck and kissed back. The Prince nipped at his bottom lip drawing the smallest amount of blood from him before he bit his own lip and kissing Merlin again, he was going to bind Merlin to him one way or another he was going to pull out all the stops to make sure his brother can't have him. Merlin pulled back and looked at him with large eyes

"Tristan." He whispered

"Shhh." The prince said, as he stood up he picked up Arthur's amour up and hung it up where it was meant to be. He then turned to Merlin and held out his hands to him "Come with me Merlin let me make love to you." He smiled, the dark haired warlock stood up on shaky legs and place his hands in Tristan's hands and smiled at him and then lead him out of the amour room.

He crossed the court yard holding hands, making everything one watch Tristan smirked knowing that Arthur will come looking for them soon, but hopefully it will be too late by the time he finds out. Merlin's face was flushed red as he walked to the halls towards the Prince's royal chambers. There was an itching need that was building up in Merlin and he guessed it had something to do with the soul mark appearing on his arm. He felt hot and cold at the same time. He watched as Tristan push open his chamber doors and swing the dark haired Wizard inside and slamming the door shut before pushing Merlin up against the door.

Merlin gasped as he felt Tristan pressed himself up against Merlin and kissed him as he rocked his hips into Merlin's hips earning himself a more that reminded him of a cat. They worked together to take their clothes off, Tristan going for ripping their clothes off not caring about anything than just getting his wizard in his bed. "Tristan." He moaned as the Prince flooded him with his magic making the wizard twist and writhe against the door as he felt the older warlock's magic warp itself around him that, it felt like the prince was already inside of him. The grabbed Merlin's leg he hooked it around his waist and then pushed himself into Merlin. He screamed as he felt the Prince enter him it didn't hurt it was more that he was over sensitive like Tristan's magic had prepared him.

Tristan set a fast paced as he Merlin against the door, and anyone walking pass the door will be freak out by the sound coming from the room the door thumping in his frame and the sounds of Merlin's screaming. It was at this moment that Tristan felt powerful as his and Merlin's magic started to mingle with each other to great their bond. Merlin hooked his other leg over Tristan's hip letting the older Warlock pulling him from the door and over to the bed, he laid out Merlin on the bed and watched him roll his hips doing the most of the work leaving Tristan just to watch him "My pretty warlock." He whispered as, his eyes turned navy blue once again as he watched his young warlock queen's eyes turn amber

"T….Tristan please!" Merlin cried out, he was close so close. Grinning from ear to ear Tristan gripped hips and slammed into him harder.

Arching his back Merlin cried out and sobbed and covered his chest and stomach as the prince snapped his hips until he empty himself into mate. Merlin whimpered and shook as he felt Tristan still rocking into him in small movements. Crawling on top of Merlin and pulled the limp Wizard up to the top of his pillows and moved them around until he was spooning Merlin. Both of their skins were shinning in sweat while Merlin felt sticky, Tristan kissed along Merlin shoulder and neck as he pulled the teen's face back to him and kissed him on the lips. "What's wrong?" Tristan asked, as Merlin pulls back and looked up at him

"W…What about Arthur?" He asked, fear creeping into his eyes "What is he going to say?" He whispered as he held onto Tristan

"You let me worry about Arthur, you need to worry about yourself." He rubbed his hands across Merlin's stomach rubbing in the younger wizard's cum into his stomach.

"I'm scared what will he do if he finds out about the baby?" He asked as he felt his bonded mate rubbed his stomach

"Shhh it will be okay." He smiled softly at him "Just sleep." He told him as he watched Merlin started too drifted off to sleep.

Merlin fell asleep leaving Tristan awake he is pleased with how things are going, however he need to get rid of that baby, there was no dome as of yet and it was only been 2 months since Arthur and Merlin was held prisoner. …Arthur has to do it…he thought, he smirked to himself as he thought of how to get Arthur to hurt Merlin…it needs to be in front of everyone, make it look like Arthur is unstable…he thought as he ran his fingers up and down Merlin's back.
