The Stained Marble
Chapter Seventeen
Part Two, Vicious Cycle
Zero's breath came out in ragged gasps as his fingernails dug into Aido's rear. The young noble's legs were spread wide and braced against the sides of the tub as the hunter groped and clawed at his backside. He fell forward and nearly lost his balance as Zero brutally rammed his entire length deep inside of his clenching hole. He managed to brace his palms up against the slippery ceramic tiles, but without anything to hold on to, his hands kept sliding as Zero slammed into him.
"Ugh! Mph!" he grunted, yet managed to bite back the sharp cry that rose from his throat at Zero's aggressive behavior.
And the water, which slipped down in between his cheeks, only made it that much easier for Zero to slide his large, thick organ into Aido's flexing hole. Within seconds, though, he was trying to spread his legs further apart, thrusting his own hips backwards as the muscles inside of him stretched and fully accepted Zero's throbbing member.
Zero growled and moved both of his hands from Aido's ass and placed them on top of his against the wall. He affectively pressed his body against the noble, trapping him again and ceasing Aido's hip movements. The noble's own member was almost forced against the cold tiles as the feral hunter pushed into his body and continued to ravage him.
Zero pulled back into a half-thrust, hitting his sweet spot, and began repetitively ramming him over and over. The hunter only paused momentarily when the pleasure became too heightened, and Aido felt him twitch inside of him. He then alternated between a deep, slow plunge into a fast, hard-hammering thrust.
"Haaa... uuuh... Zero!"
Aido's straining erection pulsed against his stomach and seeped clear juices down over his sac and in between his thighs. He longed to feel friction on his own member. He ached to be touched because he didn't think he could come from just anal stimulation after having just had an orgasm. He needed Zero to touch him.
The hunter leaned down and grazed his tongue over the two puncture wounds at Aido's neck. Zero's raspy pants were against his ear and he could tell Zero was close to climaxing.
He whimpered. He couldn't stand it any longer. "T-Touch me... please... Zero!" he begged and tried to squirm under Zero's relentless and feverish thrusts.
Zero did not deny him; he never did. The hunter's right hand left his own and fell down to fist around him tightly at the base of his shaft. He stroked his stiff organ and his testicles tensed with each passing stroke.
That warm tongue snaked out against his throat once more, tracing his wound and causing his first orgasmic tingle to surface. Zero's hips snapped back and forth in an impossible rhythm as he grunted and slammed once more into Aido's flinching hole.
A slew of jerky pulses rippled through the hunter as he released his seed inside of Aido. Yet, Zero managed to continue pumping him and breathlessly whispered into the noble's ear, "Come for me, Hanabusa."
"Mmph~! Aaah!" Aido moaned as he spilled out into Zero's hands.
The sheer intensity and abruptness of his orgasm caused quivers and spasms to wash over him in the aftereffects. He was left gasping for air as the euphoria wore off, and Zero slowly detached himself from his back, releasing his sticky member.
He felt the hunter pull out of him, and as soon as he did, Aido's knees buckled and he almost fell. Zero's strong arms enveloped him, catching him instantly. He hadn't realized it, but he'd been using his legs to steady their position the whole time so they wouldn't slip and fall. But now, his legs were shaky and he was exhausted.
"I think you've been in the shower for far too long," Zero said as he cradled him like a child.
He tried to nod in agreement but his eyes were already closing. He had half a second to think he should at least wash his backside since he was still in the shower, but the second his eyes closed, the darkness took him and he faded into a peaceful slumber.
...
Aido's ocean-colored eyes blinked open and he shifted, feeling the silkiness of the satin sheets against his bare skin. He rubbed at his sleepy eyes and groggily realized he was in his own bed again. No wait, Zero must have put him there... right?
He rolled over. His body ached in places he never thought possible, but it was still a good ache. His eyes burst wide open when his hand flopped into the empty space beside him. Where was Zero?
He bolted up in the bed and looked around the brightened room. He had to squint around the rising sun shining through the giant hole in his bedroom wall. He scanned his room, but Zero was nowhere in sight. Then he smelled it: the scent of blood.
The scent had a very distinct smell to it, and he'd definitely smelled it before but couldn't quite place who it belonged to. A tremor singed through his fangs as the scent grew stronger, and dread filled his gut. He wasn't sure why, but something told him it would be better to ignore that wafting scent, to lie back down, and pretend he'd never even smelled it in the first place. His instincts told him if he got out of that bed, followed that scent to its source, and saw who it belonged to, he wouldn't like it. He would be devastated, and yet, he found his feet falling over the edge of the bed and his hands grasping for a nearby blue, fluffy robe as he headed towards the door.
His heart thudded against his chest as he opened his bedroom door and slid out into the unlit hallway. Within a few steps, he reached the door to Kaname's parlor room from wince the scent came. He reached down, turned the knob, and opened the door just a crack. The door didn't make a sound, not even a creak as he pushed it inwards.
The noble froze. He didn't want to see what was beyond the door, but he couldn't look away. He hoped his eyes were deceiving him, but sure enough, Zero half-leaned, half-hovered over a small and fragile figure. One of her limp arms fell at her side, while the other one was gently, and somewhat lovingly, draped around Zero's head. And the hunter's head... was bent down over the girl's tender neck. His lips were pealed back and his fangs were buried deep as a thin crimson line trailed down that slim throat.
An involuntary sob escaped Aido's lips. His body flooded with a mixture of emotions as his one true love stood in the midst of betrayal. How? Why? When? His eyes blurred and his heart tore.
No, no, no! Zero promised, he promised! Please don't let this be real! I want to wake up! he thought to himself.
He clenched his eyes shut and tried to will the horrible, wretched image of the two of them away, but when his eyes opened, Zero's lips were still locked on Yuuki's pale neck, and he was still standing there, shaking and trembling. This couldn't be happening. Zero wouldn't do this to him, he wouldn't! There had to be a logical explanation. There just had to be.
Zero was lifting his bloodied mouth from that frail neck, and Aido reached up to push the door open. He couldn't stay silent about this. He had to know why his lover lied to him. He needed answers and he needed them now, or else he couldn't continue his relationship with Zero.
He leaned in to open the door, to confront his lover, but someone grabbed him from behind. Slender, cold fingers pressed over his mouth before he could startle into a scream, and another firm arm wrapped around his chest. The arm tightened around him, lifting him off the ground and pressing his back against someone's chest. But as his captor sped down the hallway and into a dimly lit study with dizzying, supernatural speed, he knew his kidnapper was none other than the pureblood himself.
As soon as they stepped inside of the study and the vampire released him, Aido was not surprised to see those dark chocolate eyes staring at him inquisitively. Kaname turned, closed the door, and then deliberately stalked towards the noble.
"Wh-what are you doing, Kaname?" he managed to spit out as the older vampire gazed into his eyes.
Suddenly, Kaname was close... too close, and his rich brown eyes were all Aido could see. They filled his vision and consumed him. He had a brief second to panic and think something wasn't right. This wasn't like the usual Kaname. In fact, he seemed too serious, and Aido felt Kaname's undeniable, ominous power pressing down on him.
And before he could even blink, his turquoise eyes locked with Kaname's and that crushing power fell over him, entrapping him. His body froze almost as if Kaname had willed it, but still, a part of his brain functioned as he panicked and thought the pureblood would devour him. Instead, Kaname remained motionless as images began to play before the noble's eyes, as if they were being played on a movie screen.
The images flashed before him, and he realized they were memories of Kaname's not-to-distant past. Kaname was showing him memories that took place not long after they'd arrived at Cross Academy.
The first memory was a glimpse of how Kaname had watched from a far as Yuuki gave her blood to Zero. The pureblood had simply watched, done nothing, and turned away.
However, the next memory was of him confronting a flustered Yuuki as he swept his fingers over the wounds in her neck. Aido couldn't hear what he asked her, but he saw the girl avert her eyes and seemingly avoid Kaname's questions.
The next memory was of the two of them as they packed to leave Cross Academy after Yuuki's transformation. Again, Aido couldn't hear what they were saying, but this time, he knew Yuuki was telling Kaname something important as tears rolled down her round cheeks. Perhaps, she was confessing to giving Zero her blood? Either way, Kaname only moved in to embrace her, kissed her cheek, and Aido watched as he whispered something sweetly into her ear. The small girl turned with wide eyes, her tears stopping instantaneously from his words. However, Kaname actually tried to move away from her now that she seemed to be calmer, but she would have none of it. Instead, she seized him by the collar of his shirt, brought his lips down to hers, and passionately kissed him. When their lips parted, she whispered an obvious, "I love you, brother," against Kaname's cheek, and the last of Kaname's memories faded from Aido's mind.
He was left speechless. He'd always known Kaname loved Yuuki, but he'd never realized just how far Kaname was willing to go for her. Still, why had Kaname shown him those memories? If the pureblood was so utterly in love with her, why had he allowed her to give her blood to Zero? And why had he even involved Aido in this whole messed up scenario in the first place? Had he used him in order to get back at Yuuki and make her jealous?
The more he thought about Kaname's motives and just how long Kaname had kept all of this a secret, the more confused he became. His eyebrows furrowed and he glared at the older vampire standing before him. "Damn it, Kaname, I'm so sick of your puzzles. Explain it in full detail."
Those chocolate eyes flickered red and he immediately took a step back. He'd forgotten his place and Kaname was quick to remind him. But just as fleetingly, those crimson eyes glittered once more and then returned to their normal brown texture.
"I already showed you everything, Hanabusa," Kaname said as his voice glided soothingly down Aido's skin, causing gooseflesh to rise all across his arms.
"Yes, but what does it all mean?" he persisted. "If you knew Yuuki and Zero were doing that, then why didn't you just tell her to be with Zero?"
He hated even saying it out loud, but if Zero and Yuuki were happy together and loved one another, then shouldn't he want what's best for Zero? Shouldn't he want Zero to be happy?
Kaname's eyes glanced beyond Aido as if reflecting upon the past. "Do you really think I'm so selfish? I really do love her. I would do anything for her, just like you would do anything for Zero. Haven't you realized that yet?"
He looked back and met Aido's eyes. "I fell for you because you were not easily broken and wildly passionate. I care for you, Hanabusa, but my love for you is not the same, nor as deep as it is for Yuuki. Yet, she told me that day when we left the Academy that her heart was torn in half. She wanted to stay for Zero, but she'd ultimately decided to come with me. I told her not to feel obligated. She stopped crying and kissed me for the first time. She said she loved me and wanted to be with me. You have no idea how much I've endured, how long I've waited for her. Zero will never have her heart," Kaname said and his dark pupils dilated.
"I-I don't really understand. If all this time, you've loved her so much, why do you continue to get outsiders like me and Zero involved?" Aido asked and avoided that piercing gaze.
"Hanabusa... I never meant to hurt you... but that day when you came to my study—" Kaname said, and his voice sounded so strained, so raw that before Aido knew it, he was pressed up against Kaname's chest.
His arms wound around Kaname's back, and his face pressed into the vampire's cool, naked chest. He wasn't sure when, but perhaps during his nap, Kaname had showered because of his fight with Zero. Now the pureblood only wore a loose silky robe.
He heard Kaname's dull heartbeat next to his ear, but then he leaned back an inch to look up into those darkened pupils. He knew both of their hearts beat for someone else, and yet, the attraction for one another was still there. It had never left. He still wanted Kaname and Kaname still desired him. The pureblood's fangs were extended halfway as if proving it, and he leaned down and struck his tongue across Aido's lips.
"Damn," Kaname huffed, sounding breathless. "We truly are cursed."
The noble moved back an inch and scrunched his eyebrows questioningly at Kaname's words. The elite vampire chuckled, further exposing his extended fangs.
"It's a vicious cycle, Hanabusa. Don't you see? You can't live without Zero's blood, Zero can't live without Yuuki's blood, Yuuki desires my blood and Zero's blood, and now, I've become addicted to your simple noble blood," he explained.
Aido gasped and tried to step away from Kaname, but the pureblood held him by his forearms. No, that couldn't be possible, could it? Kaname was lying, right?
But when he looked at Kaname again, he saw that satisfied smirk as the older vampire relished in his misery. Finally, he'd realized the true reason for all of their suffering: the vicious cycle and curse of the blood.
It made sense because as much as he hated to admit it, he did depend on Zero's blood, which he found irresistible with its unique taste and pureblood-like qualities. It was only now, after Kaname's words, he realized Zero's blood was the reason he had not regressed into a Level E, just like Yuuki's blood sustained Zero. It was just as Kaname said: a vicious cycle. The four of them could never escape one another.
But wait... he had drunk Kaname's blood first, so why was he addicted to Zero's blood?
"I drank from you first," he said, trying to voice his confusion.
"Yes, it seems that prickly hunter was more powerful than I originally estimated. Do you think I'm just messing around when we fight? For the most part, I seriously want to kill Zero, but he drank my blood as well as Yuuki's blood. He's a unique vampire and vampire hunter. He's dangerous to our kind. I should've let him die a long time ago, but of course, Yuuki refuses to let that happen," Kaname said with such a melancholy expression that for a moment, Aido didn't know how to respond.
Yet, he finally regained his senses and asked, "When did you become addicted to my blood?"
He didn't know why, but he had a bad feeling about Kaname's answer to his question. Still, he needed to know, and when Kaname's eyes shifted away from his, his heart sped up.
"It was during the last time I fed on you. I realized you tasted different because of Zero's blood. I'm not saying this is the reason I'm now addicted to your blood, but I have to admit, I'm definitely drawn to its taste. Still, there is also the fact that no matter how much I kick you around, play with you, tease you, and even abandon you, you always remain loyal to me, Hanabusa. And now... karma has come back to bite me," he answered.
But when Aido didn't respond, the pureblood looked down at him and a bit of concern creased his forehead. "I'm sorry. Perhaps, I shouldn't have told you all that."
The noble shook his head. "It's fine. I needed to know, but I'm sorry, Kaname. I'm not sure what you expect from me anymore, but just because Yuuki shares her blood with Zero doesn't mean I'll betray Zero by doing whatever with you. I'm going back to my room."
"I never expected you to betray Zero. I only wanted to offer you a comforting shoulder since we are both in the same boat... as the saying goes," he said, but his seductive voice was thick and it rolled down Aido's back like pure silk.
The blond hastily shoved his palms against that hard chest, which probably made matters worse, but he needed distance from Kaname. He needed to walk away. He'd already decided on Zero and not because of his blood.
Not too long ago, he'd made a mistake and tried to be with Kaname as his lover. He hadn't known how to love such an ancient and experienced vampire, nor had he known how to stay by Kaname's side the moment Kaname had betrayed him. Kaname had declared Yuuki his lover and hurt him terribly.
In all fairness, Kaname had warned him from the very beginning that he loved Yuuki. He'd had no pretenses over that, and still, he hadn't been ready to devote his heart fully to Kaname knowing the pureblood's heart belonged to Yuuki. He hadn't been willing to belong to just Kaname. Instead, he'd run to the first person he could find: Zero. He'd gone after the first person who had shown interest in him and used him to get back at Kaname. Of course, that plan had backfired, and he'd ended up falling for Zero.
Yet now, he found himself in a similar situation, only the roles were reversed. Now he had the opportunity to get back at Zero for his betrayal. He could use the elite vampire and hurt Zero. The temptation was undeniably there. He wouldn't mind kissing Kaname, wrapping his arms around him, and pressing their warm bodies together. He wouldn't mind mingling their tongues together, if only to see Zero's expression as he walked in on them.
But amazingly, he resisted because he remembered how it felt. He remembered what he'd felt when Kaname and Yuuki had nearly kissed out in the Academy woods, and how his heart had crumbled at the sight Zero's fangs in Yuuki's throat just seconds ago. What would he accomplish by retaliating a betrayal with another betrayal? Kaname's kisses would only comfort him for those brief seconds, and when they ended, reality would slam back into him. Zero would still be a liar and his heart would still remain shattered into a million pieces.
In that moment, he realized he loved Zero more than he'd ever loved anyone before. He couldn't share him and couldn't stand being betrayed by him. He couldn't sit by and watch Zero lie to him, not like Kaname had done. Kaname was different... Kaname was his pureblood master and someone he'd always respect. He was bound to obey him, and for this fact alone, it was impossible to betray him. He stayed by Kaname's side out of sheer loyalty, not love.
But with Zero, he realized he couldn't stay by his side because he loved him too much. That didn't make a whole lot of sense, but he'd always believed that love could conquer all. He always thought he'd stay by his one true love's side no matter what they put him through... but that wasn't real love. No. Real love meant he couldn't stand it if Zero lied to him. It meant being selfish.
Aido tried to struggle out of Kaname's grasp because he desperately wanted to see the hunter. He wanted to talk with Zero and understand why he had lied, but Kaname wasn't about to let him leave so easily. The older vampire clutched his arms and yanked him backwards into a firmer hold. With startling speed, Kaname leaned in and smothered his lips.
He thrashed against the pureblood, but perhaps, he had pushed Kaname to his limit. Those lips were demanding, assertive, and impatient. They forcefully pried open his mouth and plunged a hot tongue in without any hesitation.
In the back of his mind, Aido was screaming, yelling at himself to find a way out of this impossible situation. He knew he should force Kaname to stop, but just how was he supposed to get the ancient vampire to stop, especially when his own mouth had already opened and his tongue was moving of its own free will?
Kaname twisted his tongue back and forth and gently traced the roof of his mouth. He lined his tongue across Aido's upper fangs and licked his upper lip. The young noble felt a slight prick as one of Kaname's ultra sharp fangs came protruding out and nearly delved into his bottom lip.
The pureblood slowed his rampant kisses into softer, tender kisses, which barely brushed Aido's lips, allowing his fangs to retract as he regained control over his hunger. Nevertheless, Kaname's breathing increased, and Aido knew it was only a matter of time before the older vampire sank his fangs into his flesh.
Abruptly, the door burst open, and the silver-haired hunter looked stunned as Aido tried to jump away from Kaname's grasp. The two of them parted but the noble could feel heat rising to his cheeks, which obviously made him look like the guilty party instead of Kaname. Frustrated by the entire situation, yet glad he was free from Kaname's clutches, he stormed past both vampires and out into the hallway, back towards his room.
When he entered his room, he remembered the giant hole and found an even brighter room than before. He grabbed some black sheets from his nearby closet and a stapler from his desk and set to work. By the time the hole was mostly covered, Zero came in and cautiously approached him. His violet eyes shifted to the ground, to the hole, and then finally settled on Aido.
"Why? Why did you kiss him?" he asked.
The blond barely contained the urge to spin around and hurl a dozen accusing statements at the hunter. Instead, he calmly finished stapling the sheets to the wall, and pleased with his makeshift work, he walked to the bed and sat down.
Zero came over to stand just in front of him. His expression was downcast like that of a child afraid of the dark.
"A-Are you going to leave me for him? Are you unhappy?" he asked and began chewing his bottom lip worriedly. That was one of Aido's nervous tics, and he couldn't help but wonder when Zero had picked up his bad habit.
Nevertheless, Zero's questions registered and he tried not to glare up at the hunter. Did Zero really have a right to ask that? How could he be so clueless? Did he still not know Aido had seen everything? Well, fine. He'd spell it out for him.
"No, Zero, I wasn't planning on leaving you. And even though I saw you and Yuuki," he said and paused to study the hunter's wide-eyed expression, "I still don't plan on leaving you," he finished quietly.
Well, that answered that. Zero's expression had guilt written all over it, and idiotic tears surfaced at the corner of his eyes. Why? Why couldn't he keep his mouth shut? Did Kaname always pretend he didn't notice how much Yuuki loved Zero? Was that how he got through the day? He just turned a blind eye and buried his sorrows in someone else like Aido?
Well, the noble didn't think he could do that. He loved Zero too much and wanted the hunter all to himself.
"Hanabusa, I-I... I planned on telling you..." he tried to explain, but Aido looked away.
He didn't want to see Zero's frantic eyes; those deceitful eyes, those eyes that only saw Yuuki. It didn't matter. What was done was done, and he'd already lost Zero's heart. He sighed. He was tired. Apparently, he hadn't gotten enough sleep from his nap earlier. Either that, or this emotional rollercoaster was wearing him out.
"Hanabusa!" Zero yelled, and his voice was beyond hysterical, beyond desperate.
He bent down onto his knees before the noble and placed his hands on top of Aido's. "I swear! I swear to you, I love you and not Yuuki! I don't love her in that sort of way, but... I care for her, and yes... I can't deny that I still crave her blood. I'm sorry. I should've told you from the very beginning, but I was so scared," he said, and as his hands gripped Aido's, the noble felt a small tremor travel through his body.
"I thought... I thought everything Kaname said was true. I thought there was no way you'd ever love me or accept me. I always thought of myself as a true monster... and I never really allowed myself to get close to anyone besides Yuuki. But I-I couldn't leave you alone. Kaname was so awful to you and I just wanted to help... but then... I fell for you," Zero said, but his violet eyes shifted down towards their interlocked hands, as if the only way he could say these words was by avoiding Aido's gaze.
"When you left the Academy, I wanted to stop you, but I didn't because I thought I didn't have the right to love someone as beautiful and as pure as you. I thought after all I'd done to you, you'd be better off with Kaname and Yuuki. I truly planned to stay away, but I couldn't help but love you and worry about what Kaname might be doing to you," the hunter mumbled, but again, Zero rushed on before Aido could properly respond.
"I know I don't deserve you and I know I'm an abomination and I'm constantly afraid of hurting you, but dammit, I can't stop loving you!" Zero cried and opened his mouth to ramble on some more.
Aido quickly brought up his hand and pressed a finger to his lips. "Just answer one simple question." And the hunter instantly nodded. "Do you love Yuuki?"
Zero's head shot up and his violet eyes widened. Aido saw a flicker of doubt, but those eyes never left his as Zero answered him. "Yes, but I love her like a brother would a sister."
A bit of relief flooded over his body, which did not go unnoticed by the hunter. He tried to jump up from his knees, but Aido's words stopped him.
"You know, she loves you, and not in a sibling sort of way," he said. "This is probably why she gives you her blood and is devoted to keeping you alive, not that I'm not grateful for that."
Zero nodded again. "I'm aware of her feelings. I can sense most of them when I drink from her, but she's hopelessly devoted to Kaname. In that regard, she's stubbornly like you. She will never abandon him, and I hate that part of her, yet I admire her for it. She may give me her blood to keep me alive, but she would never betray him... unlike Kaname. She is not like that, and I'm not like that, either. I want to be with you and you alone. I didn't lie to you when I told you that earlier. Don't doubt me because Kaname lied to you. I'm not him," Zero said, searching his eyes and imploring him.
Guilt flooded over Aido as he remembered how easily he'd given into Kaname's kiss. "I-I'm sorry. I regret it," he blurted. "Kaname initiated the kiss, but I did nothing to stop him and kissed him back. He told me that the four of us were trapped in a vicious cycle, all trying to cling for one another's blood. I knew, perhaps, you needed something to keep you from falling to a Level E, but I didn't know what," he said as he stared deeply into Zero's purple irises.
"The worst part was being lied to about it. I guess I did want you to feel my pain, and in a weak moment, I let Kaname kiss me," he admitted and felt Zero flinch at his confession, but he quickly rushed on. "But then I realized I'd already been down that road with Kaname. I don't want to keep repeating my past mistakes. I just want us to be happy. I don't want any more lies between us because I, too, decided on you, Zero. I love you, and I want all of you to myself. I won't stand idly by as you are ripped away from me," he said as his emotions almost got the better of him and caused tears to blur his vision.
"I thought I could stay with you even if you betrayed me, but that's not real love. Actually, if you should ever leave me or betray me, I'll probably die from the huge wound you'll leave in my heart," he confessed and paused momentarily as Zero fisted his hands and vehemently shook his head back and forth at Aido's words.
Zero obviously wanted to open his mouth and respond to all he'd said, but he didn't need him to. He already knew what Zero would say, so he spoke again before the hunter had a chance.
"But for now, I understand that Yuuki's blood is a necessity, and we should make it a priority to look for Shizuka Hio."
With his last words, Zero looked a bit alarmed. "You think she'll really just hand over her blood willingly?"
"To Kaname, yes, she will," Aido said and gave the hunter a devious smile.
Zero rose up from his knees and onto his feet. "What are you scheming?"
The silver-haired vampire sat down next to him and lightly traced his fingers through those blond strands. He leaned in and kissed the top of the noble's ear.
"You'll find out soon enough, but for now, isn't it enough that we have each other?"
Zero's lips grazed his cheek and down to his lips. "Yes, more than enough."
Their lips met and their worries faded as their heated passion overruled everything else.
Even Aido smirked under his lover's playful tongue. For once, he had everything he ever wanted. Kaname had practically given him the upper hand and he planned to take full advantage of that damn pureblood, even if it meant using his own blood in order to get Kaname to cooperate. One way or another, he would break this vicious cycle of blood, and he would free Zero of Yuuki's hold over him.
Yes, Kaname, karma really is a bitch.
