Summary: you have endured Knives countless abusive speeches ever since Vash convinced you to babysit his brother while he ran errands in the town. Eventually it became too much, to the point you had to put your mutt in place.
warning: this fic is an absolute kinkfest, I apologise. Also heavily Trimax implied (mostly anatomy wise not actual spoilers).
Another bitter lecture on why humans were an insufferable species, those words filled with venom that bounced off your slouched shoulders. Head already pounding with a headache, you had regretted agreeing to watch Vash's spiteful twin, bearing his verbal abuse on what appeared to be a daily basis now.
Yet despite those words spat your way, like you were the very reason of his hatred for humankind, Knives still found himself begrudging spooning your smaller form. The only issue with that was you were still subjected to his rants, until they were all that filled your dreams, dreams that use to be full of nothing but pure happiness.
"Incompetent species your kind are, useless and disgusting to gaze upon. Your very existence plagues this world, may you all burn one day." You rolled your eyes, yet kept silent about how his actions contradicted his words. The arm slung lazily over your waist as your back was pressed uncomfortably into his chest, his aura suffocating.
"Do you ever shut up, I'm trying to sleep and you're grating voice is causing my ears to bleed." You sighed, voice bitter as Knives squeezed your waist.
"You dare speak to me in such a tone? I will make sure you regret every word spok-"
"You piss me off," Knives' taller form was now beneath you, the rage on his face obvious from your position a top of him. "Acting high and mighty, but then crawling into my bed like a bitch in heat. You're fooling no one bar yourself."
Knives looked furious, teetering on the edge of rage if you persisted your outburst. He was furious, until the moment you tore that silk nightgown from your body.
"Someone ought to put you in your place," You hissed, fingers embedding themselves into his platinum blonde hair, pulling at tuffs until his face collided with your cunt. As your weight sunk onto him, squashing his face underneath you and the pillow he rested upon previously. "I know you don't require sleep, that's one positive we now have all night to make sure you're returned to your brother a dumbafied mess."
The growl against your clit had your thighs shaking, suffocating Knives between them. When he made no move to advance in your pleasure you took it upon yourself, grinding your hips against his contorted face. Chasing your high as Knives clawed at your body, mind indecisive as whether to stop you or indulge you.
It took a few minutes until you felt something wet slot its way inside your folds, lips suckling at your intimate flesh. Knives had decided to indulge your humanly needs, hands gripping your ass, a need to dominate even in this particular predicament. But he'd soon find out you had no intention of allowing him an inch power, stamping out that idea like embering flames.
You greatly despised the hands holding your waist, dragging you along his awaiting mouth. None but impressed, you raised your hips to break away from his reciprocation, bile in your throat as he slammed you back down hungrily. So you let him have his fun, manipulating him to believe he had the upper hand, that he was the one bringing you unrelented pleasure as you moaned sweetly.
In reality it was painfully obvious that Knives had no idea what he was doing, having never touched or seen a woman's body. His hungry lapping was sloppy, unsure of what to focus on, sure his teasing suckling against your flaps had you keening enthusiastically but that's where it stopped. Forcing you to press your neglected clit sharply against his nose, grinding against it to offer some relief. Knives may not have been pleased with this, but it didn't matter, soon he'd be finding out just how 'in control' the fucker truly was.
Once it hit the ten minute mark you knew you weren't going to orgasm any time soon, and as embarrassing it was you didn't have a choice to stop this unpleasant mouthing. Face red as you let out an loud moan, thighs clenching Knives face as you faked an orgasm, quick to remove yourself as your eyes glared at the man smirking at you. God he looked like an idiot, and how you desperately wanted to make him whimper like one.
"You humans are such simple creatures, chasing your disgusting pleasure highs and here you are calling me a bitch in heat, when you so beautifully cum." You wanted to gag, perhaps even admit you faked it to get him to stop embarrassing himself.
Without so much as a single word you got up, crouching down to grab a locked crate from underneath your bed. Knives watched with a quirked brow, sitting up as he crossed his legs, amusement in the form of sly smirk.
"Giving me the silent treatment? You truly are petty," Unknown objects were beginning to line up on the bed's edge, Knives frowning at them in confusion. "What are these?"
"You'll know soon enough, but this bitch in heat wishes for you to properly fuck her, think your Lordship could treat me with his cock?" Your voice was laced with something, malice? No, that couldn't be it.
Knives smirked, chuckling as fingers propped your delicate face to look at him. "Who am I to deny my sweet human bitch?"
The room was filled with desperate pleas, moans soon muffled harshly by the ball gag slammed against teeth. Nails dug into the sheets, clawing frantically to try and escape.
Knives felt his drool pool around the ball gag, tears filled his blue eyes as he whimpered, jolting at another harsh smack to his ass.
"I don't know whether to be disgusted or amused that you're getting off to this," That silky voice, belonging to the only devil present in the room as you smiled wickedly down at his form, running the whip teasingly along his cock. "Next time, don't test my patience."
Another snap of the whip, Knives crying against the plastic gag, trying to crawl away from your sexual torture. Only you brought him cruelling back, pulling him arms back as you clicked a pair of pink, fluffy cuffs around his wrists.
Laughter made Knives shiver, eyes wide and filled with fear as you leaned against his arched back, fingers pressed delicately against his rim. "Good thing you've already cummed for me three times, otherwise this wouldn't be as enjoyable. For you at least." The way Knives tensed had you giggling, shoving his face into the pillow as you angled the strap on against his prepared hole.
You could hear the frantic pleas from the man, muffled as he begged for you to stop. Except they only acted to urge you on, slamming your hips into his anus, earning a high pitched moan from the usual calculated and cruel twin. Satisfaction at having turned him into a drooling, moaning mess beneath you as you pounded into him at ruthless pace.
Knives with eyes full of beautiful, bliss out tears, looked back at you, not having the strength to muster even a glare as you winked at him. He wanted to curse you, strangle you for withering him to a submissive being completely at your mercy. Yet despite it all, Knives couldn't help but find some pleasure at how you had him drooling a muffled version of your name at each thrust against his prostate.
"You likin it? What a filthy excuse of a creature, indulging in such a disgusting act of self pleasure." Your words reflected his own, cruel and condescending. Those deceitful fingers drawing lines along his spine, causing his back to arch against the touch.
Leaning against his back, breasts dug into shoulders as your teeth nibbled at his ears. Laboured breathing sounded heavenly, eyes rolled into his skull as he covered the sheets beneath you two in bioluminescent cum.
"Such a filthy whore."
"Please....no more...I can't."
"You can't? I thought you were a superior being, stronger than any mere mortal that walked this hellscape?" Knives whimpered, hiding his tears has you dragged your hips excruciatingly slow along his pelvis.
Hands placed against his chest, fingers pinching his nipples as you stilled, appreciating how his cock twitched against your cervix. You had to admit that Knives looks angelic beneath you, the feathers sprouting at random an added extra as he struggled to keep eye contact.
"You've satiated your desires, please you can't need anymore." Knives hated begging, but what else was he to do when it came to appeasing the succubus milking him until he was dry.
"My sweet Knives, you should know by now," You leaned forward, pulling the collar tighter around his throat untilheet out strangled cough. "I'm insatiable."
Knives could no longer see straight, cum dribbling endlessly from his throbbing cock, encased in your hands as you pumped the fleshlight up and down along his shaft. His mouth was wrapped around one of your nipples, not like he noticed at this point, numb to overstimulation.
A stuttering cry sounded from the blonde, releasing your nipple at the pain of coming again, fresh tears staining his feather covered cheeks. Those soft, silk like feathers encased your body, their touch gentle against your skin.
Collapsing against your chest, face buried between those warm pillows as he sobbed. Incoherent word vomit spilled from his bruised, drool coated lips. Shivering at the way you giggled, finally freeing his flaccid cock from the textured fleshlight.
Taking the collar off his neck, smiling proudly as Knives sucked in much needed air, thankful to be able to breath properly. You moved him to the side, his body limp as you circled his cock with a finger, watching it stand yet again in painful anticipation. Knives whimpered, wondering what other cruel torture you had in mind, no longer surprised at your insatiable desires.
"Still wanting more? My, my, my how adorable you are my sweet slut." Your voice was no longer cruel, you may have whipped his ass raw, choked the air from his lungs and fucked him into another dimension, but you no longer had that malicious undertone. Instead opting to sweetly degrade him, praising him for how he came for you over and over again, getting hard after each touch to his cock.
Legs hoisted over his head, Knives tried to focus on what you were doing, panting as he felt something enter him again. It was large, not to mention unnaturally wide as he grunted at the intrusive toy. What had his body convulse and contort with pain and pleasure was the intense vibrations against his prostate, drawn out whines filling the small room yet again as his legs rested against your shoulders.
"Good boy, now he can't forgot that gorgeous cock of yours." Something snapped against his tip, the small band squeezing the head of his pulsating dick. "Just to make sure you last as long as possible, don't want you coming too soon, especially now that you're on the verge of breaking."
You re-inserted his cock into the fleshlight, only this time pressing a few buttons on the side, intense vibrations causing Knives hips to buck up, back arching. You flipped him over, laying on your back as you wrapped your legs around Knives face.
"Now eat me out properly this time, I want to cover that face in my cum, mark you as my personal whore." You cooed, fisting tufts on his hair as grinded his face against your dripping cunt.
This time Knives knew what to do, mustering enough energy to suck and lick your clit. His actions were slow, sluggish as the smallest of movements were agonisingly painful to perform. Releasing your clit, Knives began lapping at your pussy, pressing a shaking thumb against your bud of nerves.
Moans spilled from those cruel lips, along with praises and mocking coos. Yet despite the way you mocked him, Knives couldn't help swelling with exhausted pride at finally pleasing you, hoping this torture would now end.
And thankfully it did, the moment you crushed his head between your quivering thighs, gushing over Knives fucked out face, you halted the devices vibrations. Freeing his abused cock and anus from their toys, Knives collapsed wings wrapping themselves around his body as if to protect himself from your satiated lust.
Gentle hands brushed themselves along those wings, weight sat upon his back as he caught his breath. Knives prayed to whatever holy being that you had had enough, eyes drooping at the exhaustion tugging at his limbs. Arms encased his feathery form, your warm body pressed against his back as kisses were placed along any exposed patch of skin. Humming filled his ears, drifting him into a much needed sleep.
"Heya Y/N! Hope Knives behaved last night, so sorry about leaving you with him again." Vash, finally back from whatever errand he was running, stood awkwardly at your door.
A smile tugged at your lips, cruel and devilish. The look had Vash confused as you stepped aside to let him in, leading him to the living room.
There, collapsed and sprawled out on soft, velvet couch was his sore, strained twin brother, face contorted as the discomfort of moving had him remain in place. Not even Vash's gentle greeting stirred Knives, who was still covered in last nights sins, too exhausted to even make it to the shower.
"Is he okay?" Vash asked quietly, noticing the many tear stains on Knives cheeks.
"Oh he's fine," You waved off Vash's concern, pouring warm water into a mug. "He was very well behaved last night, the most obedient he's ever been actually!"
Wings sprouted from Knives instantly, startling the younger twin. Knives face was bright red, hidden by the pillow that covered his face as the feathers quivered in excitement at the praise. His body reacting eagerly as if you'd take him then and there, disregarding his stupid brother's presence.
"You might have to carry him home though, he's exhausted from helping me move some furniture around." You lied, sliding some freshly made tea towards the Humanoid Typhoon, blowing to cool your own drink.
"But everything looks the same? What furniture did you move?" Vash asked innocently, warming his hand on the mug.
You quirked a brow at Knives, catching his gaze sent a shiver along his spine. "Just rearranged a few things in my room."
