A/N: I promised a belated b-day oneshot for my new friend izzanami. I can't do Inucest, just can't, so I ventured a Sesshoumaru/Naraku yaoi. Though the one for kiramaru7 was technically the first completed piece of that sort for me, this was the first attempted and I think it turned out a lot better. Story/series titled after the NIN song of the same name. This one's for you Izzi - Enjoy!

The Perfect Drug

“We had an arrangement.” Sesshoumaru stood over Naraku, glowering down at him as if he were an angry god passing judgment on one below him.

“You should know well by now what it is to trust me,” Naraku grinned.

“You should know well by now what it is to betray me.” The dog demon drew his weapon, Toukijin’s shining blade reflecting the filthy hanyou’s leering eyes.

“You don’t want to kill me, Sesshoumaru.” His tongue rolled over the words, the name in particular, as a snake would slither over pebbles in its path. “You’re only truly angry because you want the precise opposite. You want me to live. You want me."

Sesshoumaru’s stare sharpened, its edge hacking away at the being in front of him. He was sickened by what it had said, his stomach churning more so as he realized the truth in its words. The fire in his belly didn’t stop him, however, from slipping his blade beneath Naraku’s robes and sliding the fabric from one shoulder with care and deliberation.

Naraku smiled as he did the same to the other side, his carmine eyes darkening with intent as his lean body was exposed, inch by inch, sinewy contour after sinewy contour. He wormed out of the remainder of his garb, crawling on his hands and knees toward the demon lord. He rose to his knees once at the foot of Sesshoumaru’s glorious figure and reached for his white cloaked hips. He managed to pull the lord’s hakama down, met with little resistance. Less yet when he made contact with the rigid flesh that swelled between his delicious thighs, curling his fingers around it, touching his lips to its distended tip.

Sesshoumaru choked on his own breath as the hanyou's lips closed around the head of his cock, a shudder trickling down his spine as the warmth of his mouth enveloped him, sliding with amazing suction back and forth. He took his entire length, not a single gag provoked, his pace increasing as the organ swelled, all too soon so close to climax. Naraku pulled back and licked his lips, smiling his smug smile as Sesshoumaru’s gilded eyes opened on him, caught with jaw hanging open in a silent rapturous moan.

“Would you have me, or would you prefer I finish you like this?” Red eyes gleaming, silk-like tone enticing him, he proposed his challenge.

Without a word, Sesshoumaru grabbed him by his equally silky, dark locks and turned him around. He would own him, humiliate him for having shown such disrespect to the Lord of the Western Lands. He pressed his manhood between the cheeks of Naraku’s well-muscled buttocks, a little cry escaping from the hanyou as he ventured gaining entrance to him.

“Not even going to spit on it first?” The man dared question.

His inquiry went ignored, Sesshoumaru pushing his way in with force meant to elicit pain, but instead educed an ecstasy-laden sigh. The slapping sound their skin made in tempo with his thrusting sang a song of anger, of hatred but somewhere in there were undertones of delight. The way Naraku’s body accepted him, embraced him, was a kind of solace he’d never known and didn’t know why he felt as such. Strange blood coursed through his veins; not the blood of an honorable man, not one who would forget himself this way. Despite his self-trained composure and his strict lordly upbringing, he’d become something akin more to an animal, lacking self-awareness or shame.

Naraku came before he did, but he was not far behind. The shock of hot fluid slicked his track, running over him, a fountain of unabashed orgasm. He withdrew and attempted to contain his pants and shivers, then cleaning himself on Naraku’s robes and redressing in his hakama. He turned as Naraku continued to puff, trembling on all fours, lost himself still in the fuck. His climax had come, no doubt, more from how easily the mighty had fallen so well into his plans than the actual act.

Sesshoumaru paced his path of shame, on the verge of leaving his dishonor behind him when Naraku called his name. He halted grudgingly, disobliging of even an odious side-glance.

“I have to tell you,” the hanyou snickered, “I like this arrangement a lot better.”

“Our original arrangement still stands. Should you desire to make this part of our dealings, you will find yourself most disenchanted.” He began walking again. It wasn’t enough to emasculate him, he had to taunt him too?

“This won’t be the last time. You’ll be back for more. It’s a feeling even you can’t shake just like that.” He clicked two fingers together in derision.

Sesshoumaru knew as he left that Naraku was wrong but, as the weeks drew on, his resolve slowly crumbled. The loss of himself in those sensations, the forgetting who he was; it was too much not to indulge in it again and again... and he would. An addiction he could not deny. He was hooked.
