Blood is Thicker Than Water
Artoria didn't know what was worse, the fact that she was captured by the enemy or the fact that she was forced to wear this white dress while also being forced to kneel. No matter how she tried she couldn't break free of the magic bonds around her wrists or the circle that kept her pinned. Something about this magic felt familiar, thought she couldn't place it. At least with her sacrifice she gave her Master and Rin a chance to escape. If she was right about Shiro then he wouldn't leave her in the hands of an enemy. She only needed to endure this a little longer.
This pose might be embarrassing for her, as was the fact that this was... quite a bit more revealing then her usual outfits, but she would show no weakness, she was still a King.
"Still fighting I see." The haunting voice echoed from all around her. Artoria's eyes looked on the figure stepping from the shadows in front of her. Her voice was familiar, as was her appearance but thanks to the hood she wore over her head she couldn't place her. Every time she thought she was getting close to placing the voice it would get away from her, as if masked and distorted. "I'm not surprised at your strong will. You were always a stubborn one. It was admirable but at some point it got plain annoying to deal with."
"What do you mean? Are you someone who knew me?" Someone from her past, someone from her life was once again her enemy. Fighting Lancelot was painful enough, she didn't want to repeat that.
Caster stepped close and leaned in, a chill passing through Artoria's body when she lifted her chin. "Intimately." She was looking at a familiar face, hearing a familiar voice, felt a familiar touch, felt a familiar dread take hold as the identity concealing magic vanished.
A Caster, one that hated her, one that wanted to have control over her, one that knew the limitations of her Excalibur, only one person in her life fit that profile, "Morgan?"
The robe faded from the witches body, revealing the many red marks that tattooed her form, now including the Command Seal on her hand.
"It's so wonderful to see you again. Alive and moving that is. It's been a very long time, sister. Still chasing your ideals I see." When Morgan traced a finger across Artoria's cheek the knight flinched away, tugging on the restraints. "There's nothing there for you to break. My Master expects for you to be ready in time for our next fight, so you should make this easy for the both of us and stop struggling." Not that it didn't provide entertainment for Morgan but Artoria had been at this since she bound her. Hence the annoyance.
"Why are you here? What do you want from me?" Artoria didn't, no she couldn't hide the discomfort she felt to be in Morgan's presence like this. If she still had her sword, or even her spear she could break out easily. Only... there was that damn Seal to consider as well. She was trapped, completely trapped.
"What do you think I want, Artoria?" Warm hands cupped her cheeks, angled her face to look up at ice blue eyes. They say that the eyes are the window to the soul, but Artoria could never tell which one Morgan was at any given time. She was too good at faking, well one of was at least. "I want what should have been mine. Britain. Camelot. The throne." She circled around her, a wicked smile playing on her face as she came back into Artoria's view, "You."
Artoria expected everything that Morgan said except for that last thing. Why would Morgan want her? As far as she knew Morgan hated her more then anyone in the world. She wanted her dead.
"Me? Why would you..." Morgan interrupted her with a chuckle like the answer was obvious. If it was then Artoria was a fool for she didn't see it.
"Do you know what it feels like to hate someone so completely that the feeling warps itself into an entirely different emotion?" She snapped her fingers, manifesting a vial of blue liquid, "Do you know how hard it is to hate you when you have your charm, your eyes, your insane drive to keep moving forward no matter the obstacle? Especially when there are two other people in your head constantly screaming at you?"
The other two... right, there were those other versions of her. One that Artoria admired, the other that gave her the sword she wielded. She never thought what it might be like, to be at odds with yourself like Morgan was. "It... must be quite difficult."
"I don't want your pity. You should have none for me. I want you to open up." Morgan pushed the vile close to Artoria's lips but Artoria knew better then to drink random potions from people that very likely wanted her dead. "Artoria, if I wanted you dead I would have killed you. That would be much too easy and boring. You still have so much use."
Artoria still refused, growling at the witch as she tried to give her the potion again. Morgan didn't have the patience to do this. It would be easy to order Artoria to drink the potion but that would be a waste of a Command Seal. Instead she took as much of it in her mouth as she could, pulled Artoria's lips apart and kissed her. The sudden movement made the knight gasp, the warm liquid invading her tongue.
She coughed when Morgan pulled away, "What is that?"
"An aphrodisiac, among other things. I told you," Morgan walked up behind her and kneeled down at her level, whispering against Artoria's red-tipped ear, "I still have use for you."
"What other things?" Artoria was getting increasingly dizzy by the moment, her body on fire, sensitive to the touch… wait… touch? Morgan was touching her, running one hand up her thigh and the other over her clothed breast. "H-Hold on… sto… we can't… Morgan…"
"Why can't we? We already did. Although your anatomy was a little different back then. Not a slight against you, it was interesting having you be so complaint and eager to please." Her hand stopped just shy of Artoria's panties, "Now it's my turn to please you. So long overdue don't you think?"
"I don't want… please I…" Her body felt like it weight a thousand pounds, all slumped forward and unable to fall with the handcuffs holding her up. Morgan smiled against her ear as her hand pressed between Artoria's legs, already finding her wet. "N-No I… this isn't…" A moan echoed from her at the feeling of Morgan teasing her clit and her nipple at the same time, pinching them in an almost identical way.
She kept squirming but all that did was make Morgan's fun greater. When she'd decided that she had enough playing around her finger, the tip of it pushed into the enterence. Artoria's body stiffened at the intrusion, she wasn't technically a virgin anymore but this was the first time that anyone had ever been inside of her.
"You're extremely tense. I could hurt you if you don't relax. Come now your Highness, don't make me waste a Seal on this. Don't you want to feel good?" At her question Artoria's legs spread wider, much to her protest, "That's it, that's good, you're doing so good when you listen to me."
What was it inside of her that craved that praise? It was unsettling to be feeling like this while in such a state.
"Tight, tight, so very tight. Suppose this is the first time you've had anyone inside of you like this?" At her mocking tone Artoria growled and looked back, eyes narrowed, "Gods yes, there's that pretty face, that hatred of yours." She moved her finger in and out faster, driving the heel of her hand against Artoria's clit every time, wetness pooling on the tile floor bellow with every squelching sound. "It was so hard to fuck you at first, with two other voices in my head fighting for control. But they didn't know how good it could be, having the King at my mercy."
Her finger slipped out right as Artoria was nearing her high. Her hips ground downwards chasing more, "Morgan." Artoria warned, although she didn't know what for. Her mind was a mess, torn between a fight and pleasure.
"Let's see how you taste." The way Morgan sucked her finger clean reminded Artoria of that night. The flashing memories brought another sharp pain between her legs. "Not bad, your Highness." She was mocking her every time she called her that. "But not enough yet." Her hand returned between Artoria's legs but this time she wasn't stroking her clit but her cock. "I forgot how nice you felt in my hand. What do you say, shall we make another?"
Another? Another what? Another child?
"Don't… please… hurts." Morgan kept her hand focused on the tip of Artoria's cock, it drove her mad. She didn't need it there, she needed it everywhere.
"What hurts? This?" In one long hand motion Morgan stroked down and then back up, pushing drops of cum out. "Say it. What hurts, what needs my hand on it, what needs me to bring it release?" Morgan's words muddled her mind further, she was once again losing her self to pleasure.
"My… cock." Artoria answered through tight lips.
Morgan kissed her neck entirely too softly, "Does my King want to come?"
"Y-Yes. So much." She couldn't tell if these were her honest feelings or the aphrodisiac talking but Artoria was wrapped up in this feeling of euphoria, of the skilled pale hand jerking her cock off. Her hips started rolling, fucking the tight fist. Shame and pleasure flooded her all at once as she came, thick white cum spraying the floor before her. "It's not… going away…" The erect cock was still there despite her orgasm… how?
Morgan offered no explanation but moved her hand away, leaving Artoria hot and bothered and thrusting into nothing. Artoria finally mustered up the strength to look at Morgan again. The mage looked at her hand and wiped it on her dress, her smile wide as Artoria panted, cock twitching with need.
"I can't wait to taste you again, have you inside me again. Not now, we don't have time but soon I'll have you all to myself again, my dear Artoria." The kiss she gave to Artoria provided no relief to the pulsing ache between her legs. Morgan vanished in a puff of mist, leaving the King of Knight's still hard and needy, waiting until she returned.
