Merlin Uther/Arthur "you look so much like your mother" (non-con)
"You look so much like you mother." And he did, didn't he? Everyone had said so. The nurses who raised him and some of the older knights when he was still little. The statement was accompanied by a pat on the head and a smile. They said Arthur had her eyes, her hair and - when he was able to comprehend this - her gentleness.
When Uther said it he talked about Arthur's body. Arthur knew this because his father's eyes would leave his face and bear down on his frame. Arthur had always thought that the words were meant to insult. Uther didn't want his heir to be soft. So he had nodded and went to the yard and practised, practised, practised.
But now his father seemed to wait for something and the darkness in his eyes matched the one in his rooms. He grabbed Arthur's neck, his thumb placed under Arthur's jaw forcing his head up. Arthur watched the flickering candle on the table than his father.
"Sire."
"You talk to me like a bondsman to his liege?", Uther spat. His thumb had begun to move.
"Father", Arthur prompted. So he was the heir and neither soft nor gentle. Surely that was the lesson his father wanted to teach and like all of his lessons this one did not come without fear.
"So like your mother", Uther said.
"You told me. I will ... I try to better myself, father." Arthur almost winced. Speech like that had brought more than one swift slap to the face in the past. He jerked back when his father's other hand touched his cheek.
"Afraid of me, boy?"
"No." This was better. No waver in his voice that would give Uther reason to slap him. Why was his face burning then? Their relationship wasn't a close one. How could it be when Uther had to raise the future king?
So this contact was unexpected and foreign to Arthur in its execution.
Uther seemed to notice. His mouth curled in a brief, but mock smile. "Very much like her", he began. "She didn't know what to do when I wed her."
Arthur began to understand. This was the speech one of the older knights had given Arthur when he was younger. He felt his face heat up.
"There is no need, father. I ... I know what to do on my wedding night."
Uther got up, forcing Arthur to stumble after him. "Father, what-?" They stopped in front of Uther’s bed where no candle was lit. Arthur straightened up. His thoughts were raising, but nothing came of it. He finally looked his father in the eyes. Uther seemed to have waited for it, holding Arthur's gaze.
A cold voice told him that a deer must feel like this when the hounds were closing in. Arthur jerked back but his father's hand around his neck wouldn't let go. Uther used the other to grab Arthur's hair making any movement painful enough to give Arthur pause.
He understood now without finding the strength to comprehend. Uther didn't care for comprehension anyway. Nor his compliance, Arthur found out when he tried to break away once again. And how could he agree to something so unthinkable and vile?
Uther brought him in a position that might have meant a spanking when he was still young and for one foolish moment Arthur thought his shame was big enough to end his father's lesson then and there. The king forced Arthur's arm high up his back, warning him to stay still. He too went on his knees and pulled down his breeches.
Arthur expected pain but Uther only pushed an oily finger into him, moving it after some deep breaths. The terror should have made thinking impossible but it has been ingrained in Arthur that he could never afford to lose his wits. Not now, not when the humiliation of parting his legs would be his greatest.
He knew he didn't succeed when his father's chuckle came from above. Then his arm was forced higher up his back, making him hollow out his spine. Uther chose that moment to shove his cock in.
Arthur's eyes first started to water when the king let his arm go and stroked his hair. Uther did not speak of the queen again but his breathing grew louder, ending in a low groan when he pushed in all the way. After his father had moved away, Arthur was allowed to stand. He wiped away the water in his eyes with his sleeve, finding Uther staring at him when he looked up. Uther kissed his jaw then, his cheek and finally Arthur's mouth.
