Unabashedly porny, kinky AU ficlet of Dark!Willow/Faith set by the end of Season 6. Consensuality between the two parties involved is ambiguous to say the least.
Faith spasmed.
The dark-haired, sultry slayer writhed on her knees in the cell. Tight bands of darkness crushed arms together from just below her shoulders to her fingertips; only her inhuman flexibility and strength stopped the magic bonds from dislocating both shoulders. The girls in front were definitely out and proud. More darkness bound her folded-legs into a classic frog-tie kneel, invisible hands forcing them so far apart she might as well have been doing the splits. She grunted a very unFaithish whimper that would have been a scream except for the black substance filling her mouth and gumming her lips together.
Shit tasted chalky.
Whatever had happened to Red? Had to have been bad. Faith had never seen Willow as much of a threat. A lightweight even with the rumours about the nerdette stepping up with the magics. This? Red was flat-out pedal to the metal, balls-to-the wall dark. Stepped right out of the shadows of Faith's cell, her midnight hair and jet-black eyes matching her dark clothing. Goth-Willow? Sexy on a level Faith had never considered. Faith had stared at Will as much in surprise at the her easy grace as her sudden appearance. The second of the Chosen Two had thought only she could walk with that much menace with a toothy smile.
Then things had gotten so much worse.
The slayer arched against the unseen things probing her cunt. And ass. And mouth. And tiny little claws tongues fingertips on her clit keeping her just there. Will lounging on the bottom bunk, studying Faith with a little smile that scared the kneeling woman way way worse than anything else she had ever seen. Kakistos had wigged her out less. God, she needed to cum. Only it had been, what hours? Wasn't stopping. Minute Faith got close, Red wiggled a pinkie and started a new round of pain pleasure FUCK.
"So, huh, guess you're softened up now." Bootsteps on concrete. How the fuck did a mouse like Willow loom over her? "Don't worry, you'll like this bit. You get to be Miss Get Some Get Done again. You missed that in the tiny part of you that will be there forever. No matter how much you try to make everyone think otherwise."
Fingertips touched Faith's brow.
Faith shrieked. Pain rage Tara no why please hate HATE HATE--
"Good thing I figured out time dilation." Willow did that smile again. "Although technically we're actually in an overlaid temporal pocket of a demon dimension with a slower timebase respective to Earth--"
Seeing Willow's pensive frown and technobabble in the midst of this was terrifying beyond all measure.
"Not important, you always did doze off through the exposition." Willow smirked. "More about slay now, explain later. Which is what got you in here. Now, see, I was so...angry earlier. I mean, huh, Buffy and Xander actually wanted to stop me after the thing with Warren. A-and I was a little out of control and Xan might have--"
Jade green eyes and streaks of auburn through the black.
"I'm sure he's okay." Will's breath hitched. "Didn't mean to knock him back so hard. H-he should get the feeling back in his legs. Any day. Now."
Faith ground her hips as the cocks in her holes plunged in and out with fervor. Willow squared her shoulders. Back in black.
"I decided to think strategically. That was what I was good at." Willow traced her fingertips over Faith's brow again. The slayer gurgled as a ghostly touch seemed to write right on her brain. "I mean, the Watchers had the Slayer do all the dirty work. You're a spare, after all. Why can't I have a slayer of my own? You just need a little more training and...discipline."
Faith's eyes rolled back as Willow's ghostly words burned into a mind sent insane by sexual pleasure.
"Shhh." Willow mistress obey kneel love threw back her head and laughed. "We have all the time we need to make you the perfect little hunting bitch to fetch Andrew and Jonathan to me. Oh, and don't worry, I'll even let you use the sharps."
Faith's answer was a throaty mewl.
"Just ride it and accept." Willow caressed Faith's cheek with obscene tenderness. "Puppy."
