Summary: Merlin and Arthur and a pool
Notes: 1. Written for someone on tumblr who requested Merlin/Arthur and water. 2. So I'm still really new at this whole fic writing thing and I am really new at writing anything resembling porn so I was almost blushing just writing the word "cock" in this. So yeah, I hope it came out alright despite that.
This is a perfect day, Arthur thought as he leaned back in his chair with a sigh and took a sip of his daiquiri. He smiled as he watched Merlin splashing around in the pool with Gwen and Lance. He kind of loved watching Merlin like this, when Merlin didn't know he was being watched. He just looked so happy. So relaxed. After everything he had been through, Merlin deserved this more than anyone. He deserved kindness and love. And Arthur wanted so badly to be the one to give Merlin all of those things, to put that smile on his face, that it made his heart ache.
Merlin caught his eye from the pool and gave him a smile, the smile he reserved only for Arthur, the little half smirk that he used to give him before they officially started dating, when they were still trying to be subtle but couldn't keep their hands off each other, even in public. Arthur returned the smile but shook his head gently and pointed at his book when Merlin waved his hand, trying to get Arthur to join him in the pool. Merlin rolled his eyes and gave a fake exasperated sigh before diving back down under the water. Arthur couldn't help but laugh. Sometimes he forgot that they were twenty-five and twenty-seven. At first glace, Merlin, who was now attempting to do a handstand underwater, could have been mistaken for a teenager, all playful smiles and optimism. Which was one of the things that Arthur loved most about him. Even after all he had suffered already, Merlin still held onto his youthfulness, he still saw the best in everyone and in every situation, things Arthur was desperately jealous of. Arthur needed Merlin, he needed him to balance out his perfectionism and self-doubt, to make him laugh after an awful day at work with his father. Arthur knew he was lucky, knew that things easily could have gone differently, knew that he could have lost Merlin forever, without ever having had this, this perfect, comfortable, wonderful thing that they had.
Eventually Gwen and Lance got out of the pool, Gwen stopping to give Arthur a quick kiss on the cheek and Lance giving a quick wave goodbye as they walked past Arthur's chair and into the house. Arthur looked up to see Merlin lifting himself out of the pool and nearly choked on his daiquiri. Merlin looked absolutely beautiful. Arthur knew that beautiful probably wasn't exactly what Merlin was going for and that it wasn't a very macho adjective, but he was, he was beautiful. It was enough to take Arthur's breath away momentarily, Merlin's dark hair sticking up endearingly, a sharp contrast to his pale, porcelain skin, water cascading down his bare chest in little rivulets, his bathing suit clinging to his lower body so closely that Arthur could see the outline of Merlin's cock through the fabric. Merlin gave him another one of those smirk-smiles as he walked towards Arthur's chair, and then he was right over Arthur, leaning down and kissing him, swinging his leg over so that he was straddling Arthur on the lounge chair. Arthur moaned softly as he reached up to grip the back of Merlin's head, to knot his fingers in Merlin's wet hair, pull him in closer. God he loved this, loved Merlin. Merlin reached down between them and gently brushed his hand over Arthur's cock, but the touch was enough to make Arthur gasp. Merlin giggled, smiling down at Arthur, a full on smile this time, lighting up his whole face. Then he withdrew his hand and sat up, winking at Arthur.
Merlin climbed off the chair and grabbed Arthur's hand, tugging him gently towards the pool. Arthur laughed and allowed himself to be pulled up by Merlin and into the pool. Later, after Arthur had gotten sufficiently wet according to Merlin's standards, Merlin pushed Arthur up against the side of the pool and kissed him hard, their slick chests pressed up against one another, Arthur's leg hooked around Merlin's waist. And all Arthur could think was, today really is perfect.
