“Would you stop… if I gave myself to you?” Vash whispers into Knives’ ear, having just seconds ago crawled himself onto his brother’s lap.
He gently takes Knives’ hand and moves it to his thigh.
“I know how badly you want to fuck me.” he says even more quietly this time.
Knives’ eyebrows raise in shock as the heat from his cheeks reaches his ears. Almost as soon as Knives registers the words, Vash is slapped clean across the face and shoved onto the floor.
Vash sits wide-eyed and disheveled. He did not expect Knives to hit him let alone reject his offer. The stinging pain on his face only makes him feel more guilty as arousal shoots straight to his groin.
when he looks up at Knives, his brother is staring back at him baring his teeth with a bewildered and furious expression.
Vash quietly attempts to stutter an apology but Knives is on top of him in a matter of seconds making his back hit the floor. His heart drops in fear as hands make their way around his throat. He gasps, fingers desperately clawing at Knives’ own, already feeling a tingling sensation in his lips from the restricted blood flow. Before he can even think, he’s flipping Knives over so that their positions are switched. Vash attempts to grab Knives’ hands again so that they lose their grip but Knives lifts himself up, headbutting Vash with a hard thump.
Knives quickly gets on his feet as Vash is distracted by his aching head. He yanks Vash by the collar of his leather top and shoves him against the wall face first. He grabs both of Vash’s wrists in one hand, effectively trapping him against the wall. Heavy breathing fills up the silence.
Vash turns his head and growls when their eyes meet. His forehead is bearing an ugly bloody bump. With a stern expression plastered on his face, Knives continues to hold eye contact, labored breathing leaving his half-open mouth.
A few seconds pass before he finally pushes his full weight against his brother and Vash gasps as he feels what is very much Knives’ hard dick pressing against his ass.
Vash can practically hear his own heartbeat increasing as realization sets in.
A small noise escapes his mouth and his eyes widen as Knives hesitantly starts to grind himself against his rear. Knives’ breath shudders against Vash’s neck making his hair stand on end. Heat pulls in Vash’s stomach, disbelief clear on his face.
Sure didn't take long to change his mind.
While still gripping Vash’s wrists, Knives uses his free hand to snake down and harshly squeeze his brother’s thigh, making him wince. His fingers brush over the leather already finding their way to the zipper.
Suddenly there’s a hand in Vash’s pants. “Oh god” Vash whispers, reality hitting like a truck. He can feel Knives’ lips graze against the back of his neck, tracing an old scar. The slow grind is still steady against his ass. Vash’s breath hitches as Knives finally brushes his fingers against his wet cunt, albeit still covered by thin boxers. Vash can’t help but mewl when Knives starts to finger his clit over the soaked fabric. Knives inhales the back of Vash’s neck in a perverse manner. He then presses a small kiss to it, then another, then a nip at his ear.
“Vash...” he says softly. Vash curiously turns his head. Knives tilts it back even more, despite the hard angle, just to capture Vash’s lips in a gentle kiss. Vash makes a small moan in surprise, a stupid fluttery feeling spreading in his chest. So funny how he can go from nearly choking his lights out to this in a matter of minutes.
Knives loosens his grip on Vash’s wrists so that his brother can properly turn to deepen the kiss. When Vash feels Knives’ tongue against his lower lip, he opens his mouth without hesitation. Knives impatiently shoves the boxers down to finger Vash’s bare clit while moaning into his brother’s mouth. Vash can’t think straight anymore, legs now shaking so hard from adrenaline they could give out. He can't believe this is happening. The feeling of his own twin’s tongue on his, his twin’s fingers touching places he's only ever thought possible in his most guilty fantasies.
Knives pulls away from the messy kiss making Vash whine at the loss. He then leans in close to whisper in his ear.
“Just to make one thing clear-”
Vash gasps as he's forcefully grabbed and shoved over the edge of the couch. His ass is now in the air, dripping cunt on display. Knives slowly leans down over Vash’s back. “You can’t bribe me with something that I could easily take from you.” Knives says, shoving three fingers inside Vash’s pussy.
Vash lays bent over, mouth agape in shock as he involuntarily squeezes around the digits. He's much too close to an orgasm to properly voice his anger. Knives chuckles, pumping the fingers in and out, pulling a desperate sob from Vash’s throat as he fucks him.
“Fuck, you’re such a slut.”
If Vash’s face could possibly get redder than it already is, it would.
“F-fuck you.” Vash growls in between a moan.
“Already am~” Knives replies with a wolfy grin pumping his fingers in and out even faster. An embarrassing wet noise fills up the room.
Vash can feel something strange deep in his skin, a sickly sweet tickling sensation similar to that of when he uses his powers. He hears Knives moan above him as if he's feeling it too. Suddenly the feeling is in his vagina, almost pulsing. He whimpers as his own anatomy does something it's never done before. Knives eyes widen as he feels something wrap around his fingers, warm tendrils practically pulling him back in. His face goes unbelievably hot.
Vash all but cries out Knives’ name when the orgasm finally hits him; his thighs shake and vision nearly goes white. The sensation is so intense and unlike any other orgasm he’s had that it's almost unbearable. His mind is so fuzzy and numb that he loses consciousness for a split moment.
When Vash finally snaps back out of it he blinks open his eyes, vision seemingly returned to normal. But he can’t shake the strange feeling from earlier. He looks down at his wrists to see small feathers have sprouted where Knives fist had previously been gripping. He exhaustedly turns back to look at his brother only to see that he’s already making his way toward the door.
Knives has the audacity to smile at him as he grabs the doorknob. Vash is suddenly overcome with the strongest urge to knock his teeth in.
Well, this plan failed miserably.
