Okay, here starts the smutty stuff.
Arthur's hands roamed around Merlin's chest, gripping, pinching, clutching. Arthur's lips were kissing the back of Merlin's neck. Merlin could feel Arthur's chest and abdomen pressed against his back. Arthur's legs entwined with his as Arthur thrust into him. Merlin moaned with pleasure as he felt Arthur's body shake as came inside him. Merlin felt his own orgasm flood through his body and he sprayed onto the sheets. He could hear Arthur calling his name...
"Merlin. Merlin! Wake up! It's morning."
Merlin jerked awake with a start. It was morning, he was lying on his side in Arthur's bed and it had been a dream. With a sinking feeling Merlin could feel the stickiness on his stomach and knew it hadn't been just a dream. Holding the sheet up Merlin sat up and looked around. Arthur was standing on the other side of the bed looking down at him with a slight puzzlement in his eyes.
"Get up and get me breakfast. Then help me into my riding clothes. Then we will go down to the stables and you'll help lash the reins to my forearms so I can go riding. While I'm gone, you will clean up in here and go do whatever chores you have to do for Gaius."
Arthur went over to sit at the window. "Well, come on, haven't got all day."
Merlin tried to subtly wipe his stomach with the sheet as he slid out of bed. Keeping his back to Arthur as much as possible, he slipped on his clothes from the night before. As he opened the chamber doors to get some food, Arthur interjected, "Oh, and Merlin? Do be sure to change the sheets."
Merlin looked back and saw Arthur's mouth spread into a very wicked grin.
Merlin had just finished changing the bed sheets when Arthur returned from his ride.
"Well, that's at least one thing I've figure out how to do."
"So the riding went well?"
"It took a while to figure out how to stop the horse. But I finally got the hang of it. Did you get everything done?"
"Yes."
"Good." Lifting up his arm Arthur took a whiff. "Ugh. I need a bath. Go start heating some water. But not too hot."
"I think you smell fine."
Arthur looked Merlin right in the eyes and spoke softly as if to a moron. "I reek Merlin."
Merlin nodded his head and went to start some water for a bath.
Once the bath was ready, Arthur allowed Merlin to undress him again. Merlin went slow and was very careful where his eyes went. Arthur got into the tub very carefully to keep his bandaged hands out of the water. Arthur lay there in the tub with his arms out the sides feeling the water loosen his sore muscles. He leaned his head back and relaxed his whole body. Merlin started to leave when Arthur spoke without opening his eyes. "Stay. You have to wash me."
Merlin gulped but stayed in the room with Arthur. Eventually Arthur lifted his legs out either side of the tub and instructed Merlin, "Scrub."
Merlin grabbed a rag and began to wash Arthur's feet. Arthur sighed and seemed to relax even more. Merlin slowly began to massage Arthur's feet. All that kept going through Merlin's head was What am I doing? What am I doing?
Finally Arthur opened his eyes and slid his legs back into the tub. He sat forward half rose out of the tub. "My back now."
Merlin slid around to the other side of the tub. Breathing heavily now with nervousness he slowly began scrubbing Arthur's back. Eventually he dropped the rag and began messaging Arthur's shoulders. "MMMMmmmm." Arthur intoned as Merlin put a little pressure along Arthur's spine. Finally Arthur stood up in the tub.
Merlin picked up the rag again and began washing Arthur's chest. Arthur just stood there with his eyes closed breathing slowly. Merlin worked his way down Arthur's body. He began to get scared as he reached Arthur's crotch. What do I do? What do I do? Does he expect me to-? Does he want me to-? Will he throw me in the dungeon?
Deciding that prudence would be the best thing he skipped down and began working his way up Arthur's legs. When he reached the upper thighs Arthur mumbled, "Everything, Merlin."
Completely frightened now, Merlin moved up and began washing Arthur's balls. Arthur began breathing heavier. Feeling more confident, Merlin moved on to Arthur's cock. He slowly began stroking it. As he could feel Arthur swelling in his hand, Merlin let the rag drop again. He gripped Arthur harder and heard Arthur moan. Merlin continued to stroke moving his hand faster now and flicking it slightly as he reached the top.
Arthur was moaning almost continuously now. He reached his hand out to balance himself on Merlin's shoulder. Merlin looked at Arthur's face in surprise. Arthur's eyes were open and he was staring down at Merlin's hand as he stroked. Suddenly Arthur's breath caught in his throat. His hips bucked and he came over Merlin's hand. Arthur's knees buckled as Merlin gave him one last stroke.
Merlin released Arthur and stood there almost breathing as heavily as Arthur. Arthur looked over at Merlin. Merlin couldn't read the expression on his face. Finally Arthur leaned over and pulled Merlin's head towards him. And he slowly kissed Merlin.
