Sam's up for anything once she tastes blood. Ruby learned that fast. She could ask for anything, and Sam would look at her like it was the hottest thing she'd ever heard, eyes dark, mouth parted, tongue chasing scarlet drops at the corners of her mouth. The knife at Ruby's wrist could be turned against her throat or Sam's as they were fucked. Ruby could tie Sam up while she fed without her even noticing until Ruby took the cut she was lapping at away and Sam strained against the rope to get more. Sam could bite her hard enough that Ruby would bleed for her without even needing a blade.
Ruby's got her eyes set on something special tonight.
Sam stalks up the bed towards her like a predator. She looks glorious like this, the danger underneath poking through her skin like thorns. Ruby wants to nurture her into an overgrown thicket. Sam's kiss presses her back against the headboard. She grabs the front of Sam's shirt and keeps her there, biting at her lower lip. When Sam pulls back, her eyes dart, as ever, to Ruby's wrist. Usually, Ruby would make her work for it. She tangles her hand in Sam's thick hair briefly, contemplates pushing Sam's head down between her thighs, but Ruby's always been an eyes-on-the-prize kind of girl.
"You want to do the honors?" She says, reaching for the knife resting beside them on the bed. She offers it to Sam. Sam grins. Her cut is quick, methodical, and deep enough to begin welling with blood instantly. Ruby hisses. She's been letting Sam open up a vein herself the last few times they've fucked. It almost hurts when it's Sam doing it, like that power inside her soaks her every movement. Sam dives into the feast before her, sucking down Ruby's blood. Her tongue skirts the small wound like it would Ruby's cunt, teasing pressure to coax more out.
Sam won't stop on her own, not anymore. Still, when Ruby grips her hair and pulls, she lets go. She's a debauched mess without even getting undressed, head yanked back and mouth stained.
"Look at you," Ruby purrs, so proud. Sam's come far, from being violently ill from a single mouthful to taking everything Ruby can give and wanting more. She is everything promised, hunter, Boy King, the one who will rip Lilith apart and break the final seal wide open. "Look at you," she repeats, devoted. She sits up and presses her mouth against Sam's until she can taste her own blood.
Sam all but tears their clothing off. Most of it with her own hands, but her fingers are busy working against her own pants off when Ruby's shirt gets yanked over her head by an unseen force. Sam's powers come at a whim like this. When they're naked, Sam growls and pushes Ruby onto the bed. Ruby hooks her ankles around Sam's waist and pulls her close. Sam bites at her breast, tongue trailing until she finds Ruby's nipple by taste alone. She closes her hot mouth around it. Ruby tangles their fingers together and drags Sam's hand up to her other breast.
"I want to try something," Ruby says, voice catching halfway through when Sam switches to her other nipple and drags her tongue over her areola. She's more than aware that the body she's got is smaller than Sam, but sometimes, it really sinks in. Sam is big, her tongue is big when it cover Ruby's nipple, and her hands are big where they're copping a feel of Ruby's tits. And those hands...
"What?" Sam tears her mouth away to ask. She turns her eyes up to Ruby. Her pupils are blown wide and dark, partly from her high and partly from lust. The bigger they get, the more Ruby's certain that pure black will fit her. Ruby lifts Sam's right hand from squeezing her tit. She brings it to her mouth, and Sam doesn't hesitate to push to fingers inside. Ruby gets them wet, keeps eye contact with Sam to see the effect it has on her. Sam inhales heavily. When she slides her fingers free, there's a strand of spit still connecting them to Ruby's lips. She breaks it with a flick of her tongue.
"I want you to fuck me with this," Ruby says, squeezing Sam's hand. Sam raises an eyebrow.
"My fingers?" she asks.
"Your fingers," Ruby confirms, "your thumb, your fist, all the way down to your wrist, baby." She drags her own fingers down the back of Sam's hand to emphasis the words. She can already imagine the stretch, the strain. It's going to hurt. Ruby can hardly wait. "Think you can handle that?" It's a challenge. Sam's nostrils flare, and her eyes narrow.
"Yeah," she says, not a moment of hesitation, "but don't forget that you asked for this."
"I won't," Ruby promises. Sam kisses her again. She kisses down Ruby's neck, over her breasts again, down her stomach, and then those big hands of hers spread Ruby's legs. Ruby loves the demand behind it. Sam's always known how to take. She just needed someone to encourage her.
Sam ducks her head to mouth at Ruby's clit. Ruby arches her back, hand in Sam's hair again to hold her still and grind up into her face. Sam lets her mouth fall open, tongue out for Ruby to use as she pleases. Ruby can feel her own wetness trickle down her perineum to soak the sheets. She arches up and Sam licks at her folds before delving her tongue inside. She licks like Ruby's slick could give her the same high as her blood, and maybe it does, Ruby has no idea. She's never really considered it. Maybe one day she'll cuff Sam to the bed until she's desperate and see if she can sate Sam's withdrawal with her cunt. It's a delicious thought.
Sam shoves two fingers inside her. It's what Ruby likes, and Sam's a fast learner. The burn of it makes Ruby tense up from head to toe, gritting her teeth. Sam does stop, then, and some of her sweetness shines through her lust as she glances up at Ruby again, making sure she can continue. Ruby doesn't know what to do with that part of Sam. She pushes her head down again so that Sam won't look at her like that. Sam takes that as a go ahead and latches onto her clit again, sucking, thrusting her fingers in and out.
She works a third finger into Ruby, and a fourth after that, both before Ruby's really ready for them. If she was human, that'd be a problem, but she's not and this body is used to being pushed to its limits. All it does is make Ruby clench up around Sam's fingers and moan louder. She's almost there, almost. A little more and she'll be stretched open to a breaking point. Sam is licking around her fingers as though to ease the burn of them. Ruby's clit throbs each time Sam fucks them in and out.
"Last one," Sam warns. Ruby lets her head fall back and pants.
"Fuck yes." That's all Sam needs. She tucks her thumb up alongside her other fingers and demands entry. Even as stretched as Ruby is, Sam struggles to force her hand inside of her. She pins Ruby's leg down with her other hand and pushes. Ruby wills herself to relax, to take it, and slowly, slowly, she opens around Sam's fist, knuckle after knuckle sliding in until Sam is working her broad palm into her. The pain of it rips through her as powerfully as the pleasure. Sam rotates her hand for a better angle, dragging her knuckles across Ruby's insides mercilessly.
Ruby feels Sam's fist sink down to the wrist. She's in so deep, and Ruby shakes at the edge of a cliff. It only takes Sam clenching her hand slightly to push her over screaming. It damn near sends her smoking out of her body, it feels so good. Her inner walls spasm around the intrusion, and Sam stares in astonishment at how she's taken it, how her hand has disappeared inside Ruby. Every slight twitch and clench of her hand tears another moan out of Ruby's throat until finally she falls to begging, "Stop, Sam, stop. Fuck. Stop." Sam tries to hold her hand as still as she can.
"I have to pull it out," Sam says. Ruby curses.
"Get it over with." Sam works her hand out slowly. Every pull makes Ruby tense and hiss and groan. She's gone limp against the sheets. She's not sure she's ever felt so worn out, not here on Earth. She can feel herself gaping around where Sam's fist was once she finally withdraws.
"Are you okay?" There it is again, that sweet concern. Ruby's instinctive recoil from it is dulled by her own exhaustion, and for a moment, she meets Sam's eyes. She could pull Sam up. She could kiss her, softly, without the teeth or the violence they're used to. She could tell Sam she loves her. It's in Ruby's hands to nurture roses among the thorns, but Hell is not ruled by love.
Ruby reaches for the knife again and cuts her stomach. Sam's eyes latch onto the wound instantly, all worry about Ruby forgotten. She ducks her head and drinks, and Ruby rides out the aftershocks of her orgasm listening to Sam lapping up her blood.
