Vampire Heat

Chapter 1:

It has been two hours since that incredible explosion of an orgasm that Kaname had given him. It should have been enough, till at least tomorrow night. Problem is it really wasn't. He needed more and it was driving him crazy.

Kaname was currently spooned in behind him, sleeping the blessed sleep of the sexually exhausted, where he should be. ARGH!, he needed more. He can't focus on anything else.

His rose colored, male nipples were pointed so much they hurt. His dick was so ready for action, that is was weeping for it, quite literally. His heart rate was already in high gear, as if he'd been running a marathon, and the sheet under him was getting soaked with his perspiration.

He decided he needed a distraction. He closed his eyes and tried to picture himself resting up against a tree, with the sun shinning down on his face and his eyes closed, basking in the warm sunlight. That's when Kaname moves over him and pins him to the tree. He moves closer for a kiss.

WAIT! He was supposed to try to get is mind off of how desperate he needed Kaname. His eyes snap open, at that thought and tries again. This time, he's lying on a sandy beach, under a star lit night sky and a crescent moon. He can hear the crash of the waves and feel the breeze skimming over his body. He feels something down, playing with his cock. Kaname was smiling at him as he palmed him.

Zero's eyes flew open again and it seemed as if his heart rate increased. He swears he could still feel Kaname palming him. When he looked down, he saw his own hand rubbing up and down on him. A groan escaped his lips, a small one. Oh god, he needs to get control of his own hands. This is the second time in one night he didn't realize he was doing something with his own hands. Another groan that he couldn't suppress escaped. He needs to go to the bathroom so he could jack off, and hopefully get some sleep.

Slowly, but carefully, Zero got up and out of bed so as to not wake up his mate and silently padded over to the bathroom. Damn, he didn't grab the lube, which is ok. Zero walked over to the toilet, pulled his PJ's down his legs. He never wore underwear, he's all commando under his pants and that's the way Kaname prefers it.

He takes one hand and leans forward to brace himself again the wall behind the toilet. He knows he'll need the support. The other hand moves to rub his cock. His own hand had never felt so good. He had to fight back a moan. Almost as quickly as that silent moan escaped, Zero fisted his silken rod, moving his thumb over the slit at the top of the head. His hips bucked into his hand. His eyes closed, head thrown back, and mouth gaping open.

He moves his hand down and back up, the swiping of his thumb of the slit again. His hips continue to buck into his hand, as he struggles even harder to stay silent. All the while, as the seconds pass, the low slight burn of need for release very quickly escalates into an all consuming fire of need.

'Oh god, oh god! Why is this happening to me? Oh, oh, yeah, there. Right there, almost… more, need more. Faster, harder, fast..' The thought stopped in his head as his orgasm slammed into him. He barely had enough sense of mind to aim for the toilet. The force of his release was so powerful that he couldn't stay silent any longer, but he barely kept it as quiet as possible.

A few passed and a sudden realization dawned on him. 'SHIT! One of the best hand jobs I've given myself, but it's not enough. It's worse, shit, it's worse. What am I going to do? What the fuck is wrong with me? I don't want to make him worry about me or start to look at me like I'm some kind of freak. I won't tell him anything. I'll have to figure this out on my own. He gets up off the floor and silently pads back into the bedroom, not bothering with his PJ's. He goes to stand at the foot of the bed, and stares at the beautiful and wonderful brunette asleep in the bed. At some point, after Zero left the bed, Kaname repositioned himself to sleep on his back.

He doesn't look like the powerful, in control, and sometimes frightening Pureblood at the moment. He looked like an innocent little cherub, completely at peace. Zero had been trying to resist waking this peaceful, little cherub, but he can't resist anymore. He must have his lover. 'I'm sorry. I know you're exhausted, but I will give you as much pleasure as I can.' He thought as he moved to his side of the bed, opened the drawer to his nightstand, grabbed the lube, and climbed up onto the bed.

Zero hooks his finger at the front of Kaname's pants and pulls it down enough to give him just enough room to play. Just looking at the yummy flesh right between Kaname's legs, he can't hold back. He must have it.

He moved lower over Kaname's limp cock, eyed the delicious looking organ, lowers his face, and sticks out his tongue to lick the head. Mmm, 'Oh god, his tastes soo good. I need more.' He thought.

His own erection is using his stomach as a drum to beat upon. He opened his mouth and wrapped his lips around the head. He moved his tongue around the head and up through the slit. A moan escapes Kaname and Zero lifts his eyes to look at Kaname.

He's still not sure if Kaname is awake, but he continues. He takes Kaname's semi-hard erection into his mouth and sucks on like it was his favorite sucker, as he moves his head up and down. Slowly at first, savoring the flavor that is Kaname.

Another moan, louder and longer this time. "Zero…" Kaname said at the end of his breathless moan. "Yes Kana?" Zero said right before he went back to suck on his favorite, Kaname flavored sucker. "Mmm, you taste so good Kana, I can't get enough of you." Kaname hips buck, his erection now sliding down Zero's throat. Zero knew just how big Kaname was and relaxed his throat so he wouldn't choke.

"Oh god, Zero… don't stop… don't st… I'm going to cu…" is all Kaname manages to say before his load is shot into Zero's waiting mouth. Zero doesn't wait for Kaname to catch his breath. He grabs the lube, coats his own entrance and then Kaname's erection before it begins to get limp. He moves his hand up and down a few times before Kaname's hips begin to move again.

Zero moves to straddle his hips. "Zero, hurry…" Just then, Zero slid himself down upon Kaname, causing both to shout in unison. Zero knew he wouldn't last long, but he needed to, for Kaname. He wanted Kaname to release with him at the same time.

He was trying to keep it slow and pleasurable for both of them, but the burn, the need for his own release won't let him. "Zero, slow…down. Please…sloooower, oh god, Zero. Awww, fuck it!", and before Zero knew what had happened, he was lying down on the mattress, Kaname over him, pounding into his prostate like a piston.

Yes! This was what he needed. "Kana… harder, HARDER! Yeah, there! There! Awww fuck… I'm CUMMING!" He arched his back, closed his eyes shut as a deep growl emerged from his throat. While he makes a mess of both his stomach and Kaname's, right after he growls, his eyes open as he moves forward to latch onto Kaname's neck. The action was so unexpected and the bite so pleasurable, that Kaname is pushed over the edge of his own release, cumming inside of Zero, a long pleasured growl could be heard from Kaname.

When Zero woke up next, he was snuggled in tight in the arms of his beloved Pureblood. 'Kaname, what is wrong with me? I'm acting like a teenager that lets his hormones control him and his cock leading the way. Is this some kind of virus that I caught? Is it even possible for vampires to get sick? Oh shit, what if it a virus and I passed it on to Kaname? Oh shit, what am I going to do? I need to call a doctor and make an appointment, before I make Kaname sick, if I haven't already.' Zero was so lost in his thoughts, he didn't notice Kaname waking up next to him.

Kaname was lost in his own thoughts. It seems that Zero was in heat. He behavior and sexual needs show that he's in heat, but more then that, Zero's scent has altered, calling to any male vampires in the area. SHIT! That's not what they need. Ok, the first thing he needs to do is send all of the male staff on vacation. Then talk to Zero, I wonder if he knows what is going on? How will he take the news?

But before Kaname could continue his thoughts, Zero moves to get up out of bed and heads towards the bathroom. Kaname get up and calls for Seiren. "Yes Kaname-Sama." She says as she kneels down on one knee, head bowed and her right hand over her heart. "Seiren, I need you to send all of the male staff on vacation, and cancel all of my appointments and meeting, for the next two weeks."

Kaname knew she would never question, just obey. She got up to follow his instructions. When she was gone, he headed for the bathroom, where he heard the shower running. His mates' scent calling him, enticing him to forget the talk they need to have and just go claim him. The begging moan slips his lips, but it was enough to alert Zero to his presence.

"Zero, when you're done with the shower, I would like to talk with you please." is all he can say before he looses control and jumps all over his lover. Damn, this is going to be harder than he thought. How is he going to have enough control to explain things to Zero if he can't get past the lust fog haze his brain is in when ever he catches Zero's scent? He must fight it, or he'll think something is wrong with him, if he doesn't already that is.

It doesn't take Zero long to finish his shower and to come out with a towel wrapped low on his hips. Kaname couldn't think past the sight of Zero standing there in front of him with only a towel about him and still dripping wet. To add to the problems, his scent was filling his nose. "Kaname!" Zero yelled. Kaname shook his head and apologized.

"I think it's past time I sat down with you and explain something simply termed as 'Vampire heat'. He pauses to give Zero a chance to say something, but he doesn't. "Simply, vampire heat is when a male vampires body prepares it self for conception. It's quit literally a vampires biological clock stating it's time for a baby. The symptoms are simple while the experience can be harder to deal with. More hormones would flood the blood stream causing that vampire to want to have sex more often. The only temporary relief to be found is in that vampires mate, more specifically, their semen. If the vampire were to try to take care of their own problem with their own hand, it would only intensify the need, not diminish it. Since vampire heat effect only male vampires, other males would be attracted to the scent of the one in heat. Vampire heat effects only male vampires that are bonded to other male vampires…"

"Kaname, are you trying to tell me I'm in heat? Is that why I have so horny and out of control lately?" is the question Zero asks, interrupting Kaname's explanation of Zero's condition. "Yes, not that I'm complaining. I love you being out of control." Kaname chuckles, but continues. "You do understand the other things I was also trying to explain? Zero, you're in vampire heat. It's what enables you to become pregnant with child and if you go around another male vampire, they will catch your scent and loose control. They won't care that you are mated, bonded. They will just simply take without asking for your permission.

Zero couldn't believe what he was hearing. "How long will I be in heat? If I become pregnant, will I still be in heat? Oh, I can't believe this is happening to me." Kaname can hear the whimper in Zero's voice and smell Zero's need for him growing again, but he's trying very hard to help Zero come to terms with this whole thing. It's a lot to take for a born vampire who goes through this, but Zero was human-turned vampire. To top it off, up until now, it was widely believed that only born vampires would go through the heat, but Zero is an unusual case to begin with. He's mated to a Pureblood and the blood might have something to do with it. "Under normal circumstances love, the heat lasts for a couple of weeks. If pregnancy results during that time, the heat eases as the need for the additional hormones is no longer needed. However, this is not a normal situation. Up until now, it was believed only born vampires could go into heat. I will need to call my physician to come and take a look at you. Since he is male, I won't leave you alone with him."

By now, Zero was over whelmed with the news, feeling very tired still, but even more, needing Kaname again. Damn, is it possible to die from need and not get it when you need to? He didn't think so before, but now he's really starting to wonder. Kaname speaking up interrupts his thoughts. "You're tired. This is a lot to take in at once. Why don't you lie down, try to get some sleep? I'll call the doctor to come out later this afternoon."

Zero started shaking his head when Kaname mentioned trying to get some sleep. Yes, that's what he needs and he knows it, just as he knows he won't be able to until Kaname fucks his brains out. "I need you again before I can sleep. I'm sorry. I feel like I'm using you, but I need you. Please come to bed with me?" Zero asked as he looked away ashamed of the mess his body is creating and feeling like he is truly using Kaname.

Kaname hates seeing that look on his beloved's face and he moved to embrace Zero. The sight of tears streaming down Zero's cheek breaks his heart. "Aw love, sweetheart, please don't look away from me in shame. Easing you through your heat is one of the greatest pleasures I would love to give and If in the process you become pregnant, I would be blessed and honored to have you as the mother of our children." Kaname moves back and gently places both palms on his cheeks to get him to look at him. "I love you Zero. You are not using me. I love you, treasure you, and thank God every day that I have you back in my arms. Let me ease your needs, please."

Zero was awed, by the truth and love he could feel and see in Kaname's eyes, which only brought him to crying even harder as he moved closer to embrace Kaname around the neck. "You are so wonderful, What have I done to deserve you?" Kaname could only chuckle as he moved Zero just enough to kiss Zero on his soft, plump, succulent lips. Zero moans softly when Kaname swipes his tongue along his lips, seeking permission to enter.

A couple of hours later, Zero is sated and sleeping for the time being. Kaname is wearing his PJ's and sitting in his study while talking to the doctor over the phone. "Yes doctor. I'm sure he's in heat. He's showing all of the signs of heat, but I need you to come do a check up on him. We need to be sure. I'm concerned and I need to make sure he won't suffer any unusual side effects of his heat and we need an understanding of why he went into heat to begin with. How soon can you come out here?"

"I can be out there this evening at 7pm. Is that acceptable Kuran-Sama?" the doctor asked. "Yes, that would be perfect. Thank you. Remember our agreement to your discretion doctor." "Yes of course Kuran-Sama. I will not betray you or Kiryuu-Sama." The doctor replied nervously. "Good, see to it you remember it at all times. We will see you tonight." Kaname said just before hanging up the phone.

Having the doctor come out at 7pm should give Zero enough time to rest up, shower again, and eat. Hopefully, Zero's need can wait until the examination is done. Feeling tired himself, he traipsed back to the bedroom and carefully climbed into bed to not wake up his exhausted mate, and spooned in behind him. As tired as he was physically, one thought kept coming back to him like a specter hiding in the shadows that won't leave him alone. A child, they could have a child together. He didn't think it possible since it was believed only a born vampire could get pregnant. Up until now, he believed they wouldn't be having any children and had resigned to that knowledge. Now it's possible. He wants to have children with Zero, but how does Zero feel about becoming pregnant and carrying a child in his belly for 9 months? He can only hope that Zero would want that too, but feared it would be too much for him. Unfortunately, Zero may not have a choice. The heat could very wll take that choice from him.
