Disclaimer: If I owned Kira and Setsuna as Miss Kaori Yuki does....you would either be running or drooling. And the song 'The Perfect Drug' is by Nine Inch Nails :D!

Warnings: Yaoi....shounen-ai....swearing...OOC up the yin-yang...implications of sex....maybe sex later....incest is also implicated. Yadda yadda, that's why it's rated R ^_^;

This is what happens when I get songs stuck in my head (oh, and if the Demoness tells me to write a story!) -_-; Well, sometimes. I dunno...I just kinda pictured Kira in a short, skimpy towel, singing along with Nine Inch Nails and I was like...holy shit. Inspiration! Da da da da! *sweatdrop* Alas! Maybe I should let you all go and read? o.o;

The Perfect Drug

//I've got my head but my head is unraveling Can't keep control, can't keep track of where it's travelling I've got my heart, but my heart is no good You are the only one that's understood.//

The deep, tenor voice sounded along the walls of Sakuya Kira's room, as the aforementioned youth proceeded singing along with the song playing from his stereo. Lately, Kira's love for singing had been as secret as the stash of porn beneath the paneling under his dresser. Today that would change.

//I'd come along but I don't know where you're taking me I shouldn't go but you're reaching, dragging, shaking me Turn off the sun, pull the stars from the sky The more I give to you...the more I die //

Today was definitely a day of change, as a short-cut, golden-haired freshman made his way up the stairs to the room of the aforementioned Kira. Setsuna Mudoh was on the lookout for a sanctuary. His little sister, Sara, had been chasing him around, getting on his case about something she found in his journal that didn't please her interest. And where else to go when your incestuous kid sister is after your ass, than to your best friend's house?

//And I want you... And I want you... And I want you.. AND I WANT YOU!//

Kira's body swayed softly to the beat of the music as the sound drifted around him. He had just gotten out of the shower and was only in a short towel wrapped around his waist(Yummy! Inspiration! *drools*). He was so absorbed into the song that he didn't even realize Setsuna was outside the door...listening ever so intently...

//You are the perfect drug, the perfect drug, the perfect drug... You are the perfect drug, the perfect drug, the perfect drug//

Setsuna pressed his ear against Kira's door...the very instant he heard Kira actually singing, he could hardly bear the disbelief of it all. Part of that disbelief belonged to the fact that Kira was singing...the other half was all about how damn magnificent he sang. Even Setsuna had to admit that the changing tones and emotion Kira was singing with had a new sensation going through his mind and body that he'd never felt before. The very moment the song got lower and down to a soft whisper, he'd nearly felt himself shiver.

//You make me hard, when I'm all soft inside I see the truth when I'm all stupid-eyed The arrow goes straight through my heart- Without you, everything just falls apart...//

Kira's previous swaying and voice had become more profound as he sank deeper into the depths of the song, his eyes closing on their own will. Setsuna meanwhile, was having a hard time trying not to tremble at the sound of Kira's voice mingling with the fast-paced beat of the song. The very note that his voice hit on each word didn't make Setsuna's task any easier, as he was practically on his knees against the door. He was having a mental war with himself over whether he should open the door or just sit there and continue listening to the notes and lyrics flowing from his Sempai's mouth.

//My blood it wants to say hello to you My fears they want to get inside of you My soul it's SO afraid to realize- How very little good is left of me//

Setsuna slowly opened the door wide enough to see Kira, eyes closed, lips parted in song, slender, bare, yet muscled body swaying in tune...and suddenly found himself marveling the sight. Looking at Kira right then was like reading a really great book, you never want to stop. Cautiously, Setsuna sidled into the room and shut the door quietly. It wasn't too hard to do, since Kira was blasting the music to volume 38 and still managed to sing above the stereo. Setsuna lay back against the wall by the door, watching as Kira sang his heart out, a blush plastered to his face.

//And I want you... And I want you... And I want you.. AND I WANT YOU!//

"...It's so strong...yet.....beautiful..." thought Setsuna momentarily as he wiped away the thin trail of saliva escaping the corner of his mouth. He'd been drooling, not knowing whether he was describing Kira's voice...or his body. It wasn't unusual for young Setsuna to be thinking such things about his sempai though. All those years with that ever-seductive man protecting him...Setsuna himself practically felt like one of those crazed schoolgirls whenever he thought about it. He was barely lucky enough to catch himself before he might've actually giggled like one of them too.

//You are the perfect drug, the perfect drug, the perfect drug You are the perfect drug, the perfect drug, the perfect drug You are the perfect drug, the perfect drug, the perfect drug You are the perfect drug, the perfect drug, the perfect drug//

Kira had felt as though there was another presence in his room, but threw it off as being paranoid...Surely no one would be in his room at the moment besides himself. He'd already locked the door downstairs so that no stalkers could get in, and he doubted that Setsuna needed any help today. Yeah, he had given Setsuna a spare key for one of those 'just in case' reasons like if his mother was giving him hell, or if he just needed a place to stay. Kira still hadn't opened his eyes, for if he did, he would've seen a blushing, insanely perverted freshman seated next to his door.

//Take me if you want Take me if you want Take me if you want Take me if you want//

Setsuna had started to stealthily crawl across the room to sit down on Kira's bed, where it was most undoubtedly more comfortable than the ground. As he sat, he was able to observe Kira closer. From where he was, he could watch transfixedly as the water droplets rolled down and off Kira's back and hair...the way his chest tightened and released when he inhaled enough air to sing out the next set of lyrics.... Setsuna had even begun to notice a new scent to the air...strawberries. He was rather surprised at himself for not noticing the scent earlier. It was addictive...

//Without you...without you everything falls apart Without you...it's not as much fun to pick up the pieces Without you...without you everything falls apart Without you...it's not as much fun to pick up the pieces//

Setsuna was reveling in the feel of how Kira's voice suddenly went to a whisper, as his own eyes began to close on their own will. "He should sing more often..." was Setsuna's last coherent thought before all other thoughts were drowned out.

//It's not as much fun to pick up the pieces It's not as much fun to pick up the pieces Without you...without you everything falls apart-//

Kira immediately looked around the room, he didn't care about the paranoia any longer. But as soon as he saw Setsuna sitting on his bed, he nearly jumped. The shock quickly wore off as a revenge plot came to mind...there was still some of the song left to go. Kira smirked to himself as he started to steadily stride towards the mystified Setsuna.

Kira leaned his head close enough to Setsuna's ear that his lips barely brushed against the lobe as he whispered the last few words directly into his ear, causing the smaller boy to jump.

//Without you...it's not as much fun to pick up the pieces//

"Holy shit, Sempai!!" Setsuna yelled at Kira, eyes wide in panic.

"What are you doing here?" asked Kira, grinning maniacally.

"Er...just...Sara was getting on my case again so...I...um...decided to come here and...." a stammered reply was all that came from the blushing Setsuna's mouth, as he was now yet again fully aware of how much flesh Kira was exposing.

"...And?" asked Kira, leaning towards Setsuna. Seemed like the whole fact that he just got caught singing didn't mean anything right now. Instead, the first priority had become making Setsuna squirm.

"...And...er..." Setsuna had practically backed himself into the space where the corner of Kira's bed met wall. Kira followed his moves by leaning closer and actually sitting atop the bed.

"...And what were you planning to do here, Setsuna?"

"Hang around you I guess" he replied, blinking.

Kira was now practically hovering over a trembling Setsuna, the towel around his hips starting to loosen.

Setsuna had been just blushing before, but he felt he'd nearly had a nosebleed for a second.

Kira brought down his head so that his lips were right where they were previously.

"Just hanging around sounds boring..." Kira whispered huskily into the younger boy's ear, as he gently flicked his tongue along the outer ridge, grinning to himself as he felt Setsuna shiver beneath him.

"I think I have something better in mind..."

At those words Setsuna blushed, if possible, deeper than before, and nearly moaned when Kira took the whole lobe into his mouth. His towel was just barely hanging from his waist, like it would fall off completely if Setsuna made even the slightest move...it was tempting him like crazy.

Soon, Kira had licked a trail down to the corner of Setsuna's lips, still grinning insanely. Then he stopped.
