"Saaai," Itachi groans. "Lie down." He flops his forearm down onto the comforter.
The feline hisses in reply. Sai is turning about in endless circles on the bed. Itachi can feel each dip from his paws. The cat draws at the mattress with his paws, padding around in restless discontent. Itachi grunts when he feels sharp claws digging into his bare calves. Sai steps over him, ignoring his discomfit, and leaps to the ground.
"Sai?" Itachi calls out, more awake now and a little worried.
Itachi can hear him pad across the thick rug and then his claws click against the wooden floor. He whines. Itachi sits up and swings his feet to the floor. As soon as his bare feet brush the soft rug Sai growls viciously and crouches low to the ground.
"Sai," Itachi says lowly, warningly.
The cat looses an oscillating snarl, fur raised. His tails swish.
Itachi stands slowly, hand extended to Sai. "Sai, what's wrong?"
Another whine comes from the quivering werecat. He looks at Itachi, dark eyes full of strong emotion. As soon as Itachi recognizes it as pure, violent lust Sai leaps at him, his powerful back legs bunching and springing his body forward. The big cat hits Itachi and he falls to the mattress with Sai atop him. Immediately he shoves the werecat off and rolls above him. The vampire is snarling and baring his teeth at the hissing cat. Sai snaps at him and Itachi shoves his forearm into Sai's furry neck and holds him down. The cat squirms beneath him, wiggling under Itachi's bare chest. Sai swipes him with his claws out. Itachi hisses at the sting and Sai takes advantage of it, writhing free.
The wrestling ends when Sai's jaw locks onto the junction of Itachi's neck and shoulder and Itachi gets a hand around Sai's neck. Growls rumble from Sai's chest and he jerks at Itachi's body with his teeth. Itachi groans when his skin breaks and blood spills over. His fingers tighten on the fur at Sai's neck.
"Fuck," Itachi gasps. "Uh. Sai…"
Sai whimpers and his hips jerk against Itachi's groin. The scent of his companion fills Itachi's senses. His blood makes Itachi dizzy, his musk increases his lust.
"Change," Itachi pants. He has to hit Sai's shoulder twice for the werecat to release his jaws and look at him, clearly irritated. Itachi runs his fingers over Sai's furry face, looking into his black eyes. "Change for me."
Sai obeys. The pads of his paws dig against Itachi's skin while the claws outstretch. His fur recedes to pearly white skin and reveals his beautiful muscles and lithe form. Itachi's fingers run through short black hair instead of fur and travel down his neck and bare back, feeling the muscles beneath his skin. The scent of his blood is even stronger in this form and Itachi swallows hard.
"'Tachi." As usual Sai becomes greedy for touch in the human form. He immediately grabs a fistful of the vampire's long hair. His other hand is erratic, traveling up and down Itachi's body without priority. He runs his fingers over Itachi's cheeks and down the lines of his face. "Itachi," he breathes.
Itachi rubs Sai's thighs and slides to his erection. Sai gasps. His back arcs and he rubs into Itachi's hand. His hand seeks out Itachi's bulge and cups it but whines at the intrusion of cloth. Frenzied he yanks the waistband of Itachi's boxers down. Itachi bends his knee and allows Sai to wrestle the clothing off but then stops any further advancement.
"Slow down," Itachi commands. He presses down on Sai's back, pulling him closer so their chests brush. "You can enjoy it in this form." His fingers run over Sai's collarbone, his lips over Sai's jaw. He sniffs at Sai's neck. The delicious scent is so close to his skin. It entices him to bite but Itachi withholds his fangs.
"'Tachi," Sai whines trying to be patient.
Itachi slips his hands between their bodies and grasps him. He tugs lightly but Sai gasps at the little pressure and wiggles closer. He nips at Itachi and, grabbing a fistful of silky hair, bites down on his ear. Itachi shivers as a hot tongue scrapes over the shell. He thrusts up and cups his hand behind Sai's cock to rub them together. It's rough and jerky at first but becomes slicker as sticky liquid spreads to coat them.
"Uh, Itachi." Sai's hips drive down in circles. Furry ears poke out from his hair and his teeth sharpen into fangs. The haze of his scents increases, clouding Itachi's mind.
"Sai," Itachi gasps. "Get control."
"Feels…." His voice is rough. He grinds his hips down desperately and snarls.
"I know, I know," Itachi murmurs. "But-."
Sai lips quiver as he growls impatiently. A spotted pattern inks his skin.
"Fuck," Itachi curses. In a quick move he flips them but Sai's control is fading quickly. The werecat kicks out with claws on his toes and fingers. There's fur on his face and a smooth line of it cuts down the middle of his abs. A single tail thrashes between his legs. He's hissing and spitting viciously. He swipes three bloody lines into Itachi's chest and bites down on the base of his throat- Itachi allows him to. The werecat is panting heavily in between the rumbling that erupts from his throat. He releases his throat only to shove Itachi onto his stomach. Sharp teeth bite down into the back of his neck and a hand skims down between his asscheeks. Fingers find his hole and thrust in. Itachi winces but opens his legs pliantly. His fingers ball up the thick comforter as Sai's fingers surge deeper. Sai jerks at the back of his neck with sharp teeth, animal instincts driving him to dominant.
Itachi tries to relax as something hot and thick presses into him. He welcomes the pain as a distraction from thoughts of drinking from Sai. And god, he wants to bite the werecat. His fangs ache with bloodlust, his throat burns. His eyes are red, eager to search out his prey, but he fixes his gaze down on the comforter.
Sai releases his neck to thrust deeper into him. His panting grows heavier and his growls fade to whining moans. His claws reach out. His hands lay over Itachi's and his fingers slide between Itachi's own, teasing them to release their deathgrip on the comforter. Itachi can feel him edging deep inside him. He moans with the sensations. His long hair is tangling, falling damp past his bare shoulders. He sneaks a hand underneath him and palms his erection. Sai jostles him against the bed with his strong thrusting.
Sai's grip on his hands tighten and he comes with a growl. The hot liquid stings Itachi's raw insides. Itachi's on the edge now. Sai withdraws and Itachi can feel liquid run down his shaking thighs. He twists at his own cock, urging himself towards orgasm. He thinks Sai's moving off of him but then the backs of his thighs are grasped. The points of Sai's claws dig into his skin. Something rough and hot rubs over his inner thigh. It travels over the curve of his butt, licking his skin clean of come. The tongue teases around his achingly empty hole, lapping at it, and suddenly thrusts in, skimming his insides. Itachi comes with a groan, wetting his own hand.
Itachi lets his body collapse into the mattress. He twists behind him to grab Sai by the neck and hauls him into his chest. The younger man bucks against his tight arm but Itachi pulls him so Sai's back is touching his chest. Sai stops squirming when Itachi brushes a kiss down his neck.
"Sai," Itachi sighs tiredly. His fangs still ache for Sai's blood. He lets his mind wander around the idea of biting down, of tasting and sampling, as he lets his hands wander over Sai's body. "Stay," he breathes Sai's neck. "Stay with me. Until-."
Sai twists around in Itachi's hold to face him. Stripes still mark his face and the bones beneath are strangely angled like a feline. "Until what?" Sai asks, sharp teeth clicking around the words.
Until they take you from me, Itachi thinks. He pushes Sai's head down to his shoulder and nuzzles the furry ears that emerge from his short black hair. He ends up drawing a fang through the fur that smells like sunshine. It makes the tooth tingle and itch with desire. He runs his tongue over his teeth and swallows. "Until you find someone else."
Sai's tails thump heavily against Itachi's bare thigh and stay there, curling around his thick muscle as if they could hold him. Sai's talons ease slowly into Itachi's arms, pricking the skin. "There is no one else." His black eyes are serious as ever but desperately earnest as well.
Itachi lays a kiss over his lips, feeling the swell of hard fangs beneath the soft cushion. Sai kisses back. Itachi thinks he's done talking then, but he must just be waiting to say his piece because as soon as their lips break apart Sai gasps for air and says quickly, "You don't believe me."
"You're very young," Itachi replies.
"But I know."
"Your instincts are telling you that. But those are based on an animal's immediate desires to survive and reproduce. They have no thought of the future Sai."
"I'm not all monster."
"You're not any monster. But-."
"No. Itachi. I know. I lov-."
"Quiet little one," Itachi speaks softly, his mouth barely separate from Sai's. "I taught you your human side but you forget I'm not one. We do not use words so carelessly."
The corners of Sai's mouth turn down. "That mark, the black lines, on Sasuke, they are a sign of his love for someone?"
"They are a sign of his foolishness."
"For you they are the same thing." Something sparks in Sai's eyes as he stares at Itachi and it shifts something in the vampire's perspective, something not even sex did. Sai is no longer his charge or his student.
The first time Itachi laid eyes on the kitten, through the bars of a cage, he'd known he was been watched back just as closely. Sai was observative and patient and learned quickly. The only thong he failed so miserably at was expressing his feelings in words and coping with a world that revolved around vocal interactions and muddled intentions. Yet now it still surprises Itachi for the werecat to be so insightful about Itachi himself. Not many know him- no one but Sasuke and Shisui- but Itachi suddenly feels a touch of unease to realize that Sai has been watching him for years and taking in more than he ever expressed before.
Sai touches the pale, empty skin over Itachi's heart and traces an invisible curve like the one on Sasuke's skin. Itachi shudders and shoves the hand away.
"Sai you don't understand vampire society or what that mark means at all. It's for vampires."
"But Sasuke's is not."
"It should not have been allowed. Listen to me Sai. The lēof contract, the mark on my brother, it's an ancient binding that shouldn't be taken on by just any mated couple. Blood sharing between vampires is erotic, intimate. The two recipients of the contract agree to only feed from one another. It's sounds like simple fidelity but when it's our instinct to bite anything with blood, to taste the life of anyone we engage,"-Itachi runs his palm over Sai's groin- "with, it is a very difficult thing to agree to. Especially knowing that they would share an eternity bound to each other only and cut off from any other who could give such pleasure. If the contract is broken the partner would feel incredible pain from the disloyalty. It drives them insane if their partner persists."
"But Sasuke still feeds," Sai says.
Itachi shakes his head. "The lēof is meant for vampire blood alone. A vampire can still feed from humans without breaking the contract. It's our food source. For Sasuke's lēof to be a human…it's unheard of, Sai. It should be impossible. And even though it isn't, we still don't know the consequences."
"I'm not human," Sai says quietly.
Itachi cups Sai's jaw harshly. "Sai, didn't you just hear me? It's lifelong. The were can live just as long as vampires. And it's not meant for your kind either. Vampires don't feed from the were for sustenance."
"You don't want for my blood?"
Itachi swallows. "I didn't say that."
"Do you?"
"I won't take advantage of you."
"But do you want it?" His tails thump against Itachi's leg. When Itachi refuses to answer Sai lifts a finger to Itachi's lips. The vampire's nose flares and his eyes tinge deep with red.
"Try it," Sai coaxes with a look more like interest than seduction. But nothing's been more tempting to Itachi in all his life than this exotic werecat with quiet black eyes and fur that smells like warmth and sunshine.
Itachi's lips part and the tip of his tongue moves to lave Sai's skin. Sai moves his finger deeper over Itachi's tongue. Itachi's fang skims over it, slicing a thin line of red down the length. No blood beads up on the small cut but the scent fills his mouth. Itachi wrenches Sai's wrists to the mattress beneath their bodies and bites into Sai's neck.
His teeth sink into his skin fully and then he's sucking up the hot liquid that's tempted him for so long. His first moan makes Sai shiver beneath him. He keeps drinking, blood coursing down his throat. It seems like he barely has to swallow. A blood frenzy that he hasn't felt since his beginner hunting years settles over him, numbing any other thought. Itachi's rock-hard in seconds. Lust guides him between Sai's legs even as his mouth stays linked to his throat. He thrusts into the werecat merciless.
Sai's shoulders shake as he chuckles at Itachi's uncharacteristically clumsy and impatient movements. His fingers tug at Itachi's hair but the vampire doesn't notice. He wraps his legs around Itachi's waist and lets his hips roll with Itachi's harsh movement. Pleasurable poisons seep into his body from Itachi's fangs and his mind goes dizzy with it. The stripes on his skin grow darker as his skin pales but he stays in a mostly human form. The fangs lodged in his throat are forcing his natural side to submit. He arcs beneath Itachi and yowls when Itachi hits a tender place inside him.
Itachi doesn't think his mind can handle more when he comes inside his werecat. He bites down harder and muscle and torn skin squelch around his teeth. Sai cries out, writhing from the pressure on his neck but still drugged on lust and poison. Shaky fingers clench in Itachi's hair and tug weakly as Sai comes. The mouth on his neck loosens and the fangs withdraw slowly. Itachi's eyes are still red but the frenzy is fading from them and worry is replacing it.
Sai's panting but he reaches up quickly and kisses Itachi's bloody mouth. He licks the leaked liquid from the corners of the vampire's mouth. "Messy," he teases softly. It's what the immaculate Itachi constantly murmured over spilled milk and dirty whiskers when Sai was a kitten.
"Sai are you okay? You're shaking."
Sai shakes his head before burying it in Itachi's chest. "That felt…nice."
Itachi laughs softly. "Nice? Is that all it was?"
Sai's nails dig into Itachi as he hugs him closer. "No," he says. "But I don't know the word for it."
Itachi rolls Sai on to his back and leans down to kiss him. His midnight hair curtains over them. "I don't either," Itachi admits quietly and Sai smiles.
Sasuke paces back and forth in his bedroom. He has to hunt. It's no longer an option. In the dark of his room his red eyes are glowing. The pupils are shrunk to pinpricks and his eyes dart about the room. His throat burns for blood.
At the same time his fingernails are scratching at his mark. His thoughts are muddled with thirst but the thought of Naruto is present everywhere in his mind. Something's bothering him. Perhaps Naruto's emotions are reaching him through their connection or perhaps it is simply hungry but Sasuke can't rest. Somebody bit Naruto. Somebody that wasn't him. That alone angers him but even more his ignorance tortures him. Why was Naruto around another vampire in the first place? And where is he now? The feeding had ended which only left two options. One is that Naruto had fended his attacker off, an impossible feat for a mere human. The second is that Naruto is dead. Only, Sasuke is certain he would feel it if that were the case. Wouldn't he?
If he is still alive and in danger than what Sasuke is about to do could kill him. With every drop of blood Sasuke drinks, Naruto's body is put through hell. Guilt builds in his gut. He knows what he has to do. Even if he starves himself Itachi would force-feed him. There isn't any choice but Sasuke feels a sickening sense of foreboding. The guilt he feels now will only build and build until it finally consumes him. And eventually the pain he inflicts on Naruto will consume his lost human.
a/n: so this wraps the itasai bit up. obviously they'll still be a major characters in the story but i promise sasunaru goodness is on the way. i'm having a dilemma though. when naru and sas meet up again they're in very different states of mind then they are even in this last arc of time. if i skip ahead to that scene there'll be a huge disconnect from their current emotional development. but i know you all may be getting tired of their separation. so... i'm thinking about it.
