I lied. So I have a song I really wanted to use in this story, and I have no other way to use it besides a fighting scene, so stay with me!
Athena woke up first, before accidentally waking up Arthur with her laughter.
"Wassamatter?" He asked sleepily, his face pressed against the pillow, and his arm being thrown around her protectively.
"You… You've got a little something on your neck…" She whispered, trying to hold back giggles of dismay.
Arthur lifted his head, and looked in the mirror that was on the other side of the room. Not being able to see clearly, he stood up and walked to the mirror, completely naked, and gasped in astonishment.
"Athena!" He yelled, turning around and glaring daggers at her.
His throat, jaw, and collarbone were absolutely painted black and blue, and there were teeth marks everywhere. Her laughter died down, and she raised an eyebrow.
"Do you think I got off spot free too?"
He looked at her, a confused look on his face, and she stood on her knees, pointing at the very prominent purplish handprints on her hips, and when she turned around, there was a pair on her ass, as well.
But Arthur didn't laugh, no. He looked devastated, despite the raging hard-on between his legs. Athena sighed, and figured it was time for them to talk.
She walked to his closet, and grabbed two robes, placing one on herself, and giving the other one to Arthur, before leading him to the bed and having him sit down.
"Arthur."
He looked at her, still angry at himself that he'd hurt her.
"Arthur, I like pain." He snapped his head to look at her, his eyes wide.
"And so do you. I like giving pain in bed, and so do you. I never, never, want to see you sad because of the marks you give me in bed. Do you understand?"
He seemed to, because the next thing he did was tackle her to the bed, kissing her intensely, and sliding a hand up her robe, massaging her clit, before she pulled away from him, taking off her robe, and getting on her hands and knees in front of him. He looked confused, until she arched her back, thrusting her backside into the air, and turning her head to look at him, wriggling her ass playfully.
He stood on his knees, and used his member to tease her, sliding it up and down her soaking, waiting slit. He bit his lip as he slowly slid inside of her wet, hot hole. It was so, so tight.
Athena went to her forearms, and moaned softly as he entered her, pressing her hips back towards him.
He placed his hands on her waist, and gripped her tightly, forgetting about the bruises on her hips. When he heard her gasp, he immediately removed his hands, afraid.
"Grab them." She whispered, and he did so, and the resulting moan was all that he needed. He started to thrust into her, and did what his instincts told him to. He slapped her ass, and she called out in delight.
He pounded her into the bed, his hands leaving deeper bruises on her hips, and a distinct red handprint making itself clear on her ass cheek.
She brought a hand down her own body, and started to play with her clit, moaning and gasping as she felt herself close to the edge.
"A-Arthur!" She groaned, panting in a way that told him all that he needed to know. He started thrusting with a new pace, quick, but like he was searching for somethin-
"A-ARTHUR!"
She cried as she came, the hearth that had gone out last night suddenly bursting to life, and the dragon and lioness shown in the windowpane started circling each other menacingly.
Arthur pulled out of her, and stroked himself a few times, before he came in long strands over her ass and back, causing her to shiver in pleasure.
They lay there, spent, with Athena on her stomach, and Arthur on his back, leaning against the headboard with his hands behind his head, and a pleased, cheeky grin on his lips.
Until Merlin decided to bust in.
"Sire! Bandits were seen on the edge of the kingdom! They have numbers too large to count, and they are heading for the castle! They will be here in less than a week's time!" Merlin looked terrified, and Arthur didn't even have time to yell at him for not knocking before Athena was up, and tossing a robe on.
Merlin gasped as he caught a glimpse of the bruises that covered her hips, and then looked to Arthur, whose neck was a purplish blue painting. Merlin's face was bright red, and Athena patted his cheek, before walking down the hall to her room. Gwen was waiting there with Morgana, and they looked like they both wanted to jump her for details.
"Just help me get dressed, please? I'm sure the king is about to call a meeting."
Gwen nodded, and when Athena removed her robe, they both gasped in shock.
Athena started laughing while they both looked at her, and she grinned.
"Don't worry. You should see him."
