Why am I a Beta? Starrk's hand tightened on his sword as he felt the wave of heat travelling through his body. It started with his toes, slowly radiating upwards until it hit his brain. I'm male! This is absurd! Cursing to himself, he reached for the pills Szayel had given him. They would suppress his burning desire to mate, but only for a short time.

Of course, he knew why he was a Beta. Starrk reflected on it as he put the pills to his lips, his hand shaking, and swallowed them down dry. His other half was female and neither of them knew exactly what their true form had been, but he absolutely knew one thing about it. Female. Not all females were Beta's but all Beta's were females, and his true form as a single hollow had been the most powerful Beta in existence. Briefly, he wondered why he'd been cursed with a male form when he split. Not that it would have made a lot of difference to his current predicament, but it was just intensely embarrassing.

"Oh my god, can you tone down those pheromones? You repulse me and I'm still getting an erection!" One of Barragan's fraccion complained and Starrk favored the man with the meanest glare he could manage.

"Try to bring your cock anywhere near me and I'll cut it off." He said, his voice a hoarse growl. Despite the temptation to mate with anything that came close, he knew better. If he allowed any of Barragan's fraccion to take him they would die, horribly, and leave him completely unfulfilled. They didn't have the reiryoku to withstand his horrific spiritual pressure. Barragan did and Starrk was so desperate that he was even considering it, but… no. If they mated he would become useless for Aizen's plans and that would just be idiotic. Assuming Barragan even wanted to mate him. He glanced at the Segunda Espada, but he was looking away with a pensive look. Maybe he was deaf in the nose. He was quite old, after all.

"As if any of us would want to touch you!" That was the weird, girly yet masculine one. Like a very bad transvestite. Starrk thought that comment was particularly rich, coming from him. "Or the girl either. My god that would be so wrong." Well, that at least they could agree on.

"Oh shut up! Starrk, gimme those pills, I'm dying over here." Lilinette groaned and he passed her the bottle. She tried to take far too many but he sternly made her put the others back. Too many sent them into a temporary coma and while they'd often welcomed that, today was definitely not the time to have his fraccion incapacitated. "Why did it have to be today? Just a few more days and the heat would have been over!"

"Just our luck I suppose." But Aizen hadn't picked the time. No, the invasion was meant to coincide with many of Soul Societies best fighters being trapped in Los Noches. So now they were about to go to Karakura town. The battle was going to be interesting, to say the least. Lilinette swallowed the pills as one of Halibel's fraccion spoke.

"I'm a Beta too… um… you do realize that a fight is a prelude to mating for a Beta in heat?" Mila Rose said and Starrk favored her with a damp eyed glare.

"No. I had no idea." He snapped back and she had the grace to look abashed. "Look, I didn't start as a Vasto Lorde. I do know how this works even if I've never successfully mated." Even as an adjuchas, his pressure had been too strong. He'd started out in the mid-range of the adjuchas level and gone up with mind-numbing swiftness. Even when he was a brand new hollow, his rutting spiritual pressure had killed other hollows. Maybe with Aizen's dampening someone like Grimmjow or Barragan might survive him, but it was still a bit iffy, for Grimmjow at least. Starrk sighed, rubbing a hand over his face. Perhaps he should have taken his chances and mated a few days ago. But then his body would be busy rendering the energy absorbed into new life and disinclined to use anything to fight. Aizen would have been very unhappy with that outcome.

"It's time." Barragan announced and they all began forming their gargantas. Starrk's was the sloppiest thing he'd ever done in his life but he honestly didn't give a rat's behind. It would get them to Karakura town, that was all that mattered. After stumbling through he tried to orient himself and mentally cursed Szayel's pills. When were they going to start working, exactly? The heat flushing through his body was simply brutal!

His target was the shinigami with the kimono and the straw hat. There was a specific tactic Aizen had trained him on, specifically designed to take care of this one shinigami. Starrk knew he could perform it, he'd been practicing hard. Right now, though, he was painfully aware of his potential to become incredibly distracted and scattered. Aizen knew that too, of course. But he'd made it clear that he expected his Primera to try. If he died in the attempt, well, that was war and Starrk would be a casualty.

"So comforting. Oh wait, it's not." He mumbled to himself as he sought out his enemy. The small talk was almost non-existent. Frustrated, in a certain degree of pain and wanting to get home so he could rut on a pillow, he drew his sword and attacked.

They went back and forth, Starrk gritting his teeth and struggling to keep the heat manageable. At first, the pills seemed to be working. Unfortunately, the clash of blades was doing exactly what Mila had said it would… signaling to his instincts that he was facing an acceptable mate. Gradually, the heat began to build again and Starrk whimpered almost inaudibly as sweat began to bead along his hairline.

"HIRARI!" He glanced down to see Lilinette leaping at the white haired man. Unfortunately, he was egging her on.

"Don't worry. Juushiro won't do anything funny with that child." His opponent seemed to find it amusing but Starrk emphatically did not. He was sure the shinigami wouldn't do anything funny with Lilinette. He was less sure that SHE wouldn't do anything funny with HIM! "Pardon me, but are you well?" Kyoraku said as their blades clashed again and Starrk cursed to himself. The shinigami wasn't pushing him hard, was taking the time to study him and noticing all the oddities in his opponent. A bit of sweat trickled down his cheek and Starrk used his free hand to wipe off his face, blinking rapidly.

"…No. One moment." He rasped out before sticking his sword back into his belt. Then he reached for his pill bottle as the shinigami stared at him, taken aback. He opened it with shaking hands then jerked back in shock as a sword knocked it out of his hands. "HEY!"

"I don't know what that is, but we are enemies. If you're sick I'd be a fool not to take advantage." Shunsui said cheerfully and Starrk wanted to strangle the shinigami. Then they both looked down as they heard a scream.

"NO! STOP! WHAT ARE YOU DOING?!" Lilinette had managed to get her hands on Juushiro. He'd let his guard down, seduced by a child curled up and crying in what looked like pain. And now she was most emphatically doing funny things to him, latched to him like a barnacle with one arm and both legs while her free hand was busy in his pants. "STOP IT! OH MY KAMI WHAT ARE YOU TEACHING THIS CHILD?!" Juushiro struggled frantically to get away as Starrk bridled a bit.

"What are you saying about me?!" He demanded although truthfully, he knew. No little girl should be touching a grown man like Lilinette was touching this shinigami. Although poor Lilinette would have known how to do it even before she'd died. Starrk was aware of their dual histories, he'd remembered after his first heat as an arrancar. "Are you calling me a pedophile?" He roared and the shinigami looked up at him, brown eyes wide with shock.

"Well… I… no, but someone must have – OH KAMI! GET YOUR FACE OUT OF THERE!" Lilinette had taken advantage of the shinigami's distraction, using the brief moment to get her face in line with his crotch. She'd figured out the ties to his hakama and was threatening to do something very unchildlike to his member. "STOP IT!" Unable to stand the assault any longer, Juushiro used a kido to toss the rutting arrancar girl away. She hit the ground hard and moaned before looking at him desperately.

"I just need your cock! Please, I know I don't look right but I have to mate!" She appealed to the shinigami, who stared at her, horrified. Starrk rested his face in his hand for a moment. This would make everything worse but he couldn't see an alternative.

"Lilinette, come here!" He commanded and she whined before flying up, taking her spot at his side. He rested a hand on her helmet. "Kick about, Los Lobos!" And he took his resurrection in a burst of power.

Unfortunately, that immediately magnified the heat. Starrk groaned, bringing his guns to his head and gritting his teeth as the need for mating sang through him. It was becoming completely unmanageable and almost everyone on the battlefield was noticing. He was sure all of Barragan's fraccion were itching like they had fleas. Even if Barragan had no sense of smell, he'd be feeling the unmistakable spiritual pressure of a powerful Beta in rut. And the shinigami he was facing had no clue. Brilliant.

The bastard tried to take advantage of his distraction to cut him to pieces. Starrk took offense and fired on him before having to deal with a strange cyclone. But that was extremely easy to deal with, really. His fevered reiatsu smashed apart the cyclone and began bending at Kyoraku's shikai. That was Aizen's plan for him. All reality bending shikai's and bankai's had that fatal flaw, including Aizen's. Facing an opponent of vastly greater power, they could be rendered useless by the proper application of that power. Aizen's shikai had never suffered it because no one was stronger than him, but he'd used the tactic before to kill his enemies. Shunsui vanished in flash step just before a cero would have destroyed him and reappeared in front of the Espada, his eyes wide.

"What have you done to my shikai?" He asked and Starrk grimaced. This was NOT following Aizen's plan. He was supposed to have used that at a critical moment to gain surprise. That was lost now.

"You have a reality warping shikai. It forces other people to dance to its tune… but I am too powerful for such things. I am stronger than you." He stated the truth plainly. It really was nothing but the truth, in terms of reiryoku he was vastly this shinigami's superior. "You cannot make me play your games." Because that was the essence of Shunsui's shikai. It forced his opponents to play childish games.

"Well, that does make things difficult!" The shinigami said lightly but Starrk could sense his concern. And he was right to be concerned. To do such a thing, Starrk needed to be more than slightly superior in power. No, the gap between them was significant. "But you seem to be having difficulty fighting. And raw power doesn't guarantee a victory." Starrk grit his teeth. Oh, how he knew the truth of that.

"…" The fight began again and for Starrk, it just kept getting worse. He was firing almost blindly, struggling to avoid strike after strike. His reiatsu was spiking uncontrollably as he panted breathlessly, vaguely aware of how tight his pants were. This was… horrifically arousing. Why did the damned shinigami have to be so strong? He would clearly survive a mating and sire worthwhile cubs. His instincts were going mad! Finally, the Coyote could take no more.

"Stop!" He screamed at the shinigami and for a moment, he feared that Kyoraku wouldn't listen. But the man surprised him, jumping back and taking a breather. "I… I cannot fight you. Please, I've done all I can." That was directed more towards Aizen than his opponent. His overlord didn't seem to be paying any attention to him at all, but that could be deceptive. "I can give you the victory in less than five minutes." That wouldn't be a very satisfactory mating, but Starrk would take what he could get. "Just please… please…" This was the most embarrassing thing he'd ever done. What would the shinigami think? Was he even interested in males? "Please fuck me." He finished, closing his one eye as he felt his face heating with embarrassment.

"I… don't… what?" Shunsui said, sounding lost and confused. The white haired shinigami beside him was staring, his brown eyes wide. Starrk opened his eye and looked at them, realizing he had to explain.

"I… a long time ago, Lilinette and I were actually one hollow. When we separated, we took these forms. I don't know why I'm a man. I shouldn't be. As one hollow we were a female, a Beta, and I'm still a Beta. I'm in the middle of my heat cycle and you destroyed my pills." Starrk couldn't keep the anxiety out of his voice at that. He'd really, truly needed those. "Hollow mating starts with a fight, always. This is driving me insane… if you mate me, I'll be in a semi-conscious state for hours as my body renders out the reiatsu infusion. Please, just a few minutes and the victory will be yours." He appealed to them. If the shinigami with the chestnut hair could stomach the idea, he would easily defeat the Primera Espada. Shunsui tilted his head to one side, a smile on his face.

"A few minutes? I have more stamina than that!" He said teasingly and Starrk's heart lurched. The shinigami wasn't rejecting the idea out of hand. He wasn't sure why, but he wasn't. "Hmm… it's quite a sacrifice… Soutaichou will no doubt be impressed with my commitment to my duty…"

"Shunsu! No one will believe that in a million years!" His comrade snapped and Starrk blinked at the way the white haired man was blushing. The chestnut haired man laughed, but then became more serious.

"Indeed. But given the way he's escaped my shikai, I'm afraid this is only practical. And I believe his story. It explains why that poor child attempted to molest you. She was in heat too?" Shunsui asked and Starrk nodded. "I see… well, we do need a bit of privacy. If you're serious about this, put those guns away." He commanded and Starrk felt the instinctive pull to obey a strong male. Shoving his guns into his belt of pelts, he waited until the shinigami sealed his weapons and put them away. He might be in lust but he wasn't an idiot. He wouldn't go near the man with those weapons out.

Soon they were in a nearby alleyway and Starrk was bent over, his arms against the brickwork. He moaned softly as fingers breached his entrance and could almost feel the shinigami's confusion as he found the Primera was already damp and flexible. His anatomy was male but it was behaving in a female way… Szayel had commented on that too, when he'd examined the Coyote during a heat cycle.

"I know, I have a case of gender confusion. Please, just take advantage of it." He suggested and Shunsui laughed. There was a soft rustle of fabric and Starrk groaned as he felt a hard cock breeching his entrance, sliding into his tight, trembling body. It wasn't the least bit painful. No, it was just right, scraping across his insides and stimulating him in ways that were unbearably good. After denying his heat cycle for so long, anything would have been good, but this shinigami was big. Skilled too… Starrk writhed in pleasurable torment as the man behind him began to take him in a quick, hard rhythm. After a few thrusts that heavy cock found his prostate and Starrk arched with a tiny scream, his fingers digging into and crushing the bricks. His head seemed to whirl and he howled without thought, the sound of a wolf hollow satisfying a heat. Lilinette yipped along with him, her tinny little voice echoing through the dark alley.

It took much longer than five minutes. The shinigami rutting against him seemed to be in no hurry and Starrk panted as his insides were abused, his whole body trembling at those hard, skillful thrusts. A hand gripped his length, stroking him in time with their movements and it came to Starrk that his lover was experienced with men. He'd honestly never expected that and he was very, very pleased.

"Cum for me arrancar. I want to see what you look like." The shinigami commanded and Starrk whined deep in his throat. He really didn't want to do that. He wanted to get the reiatsu shot before he took any pleasure for himself. As strong as this man was, there was the potential danger that the Primera's release during a heat would kill him. He couldn't tell Kyoraku that, though, and the hand on his cock along with the length inside him… it was simply maddening.

He couldn't hold back. He wanted to, but he just couldn't. The Coyote howled as he found his moment of pleasure, his spiritual force exploding out from him in a way that was reminiscent of his resurrection. For Shunsui, it was like being in the eye of a hurricane. That brutal spiritual pressure rose to a soaring pitch, but the vast majority of the force was surrounding them, not touching him. What did touch them felt like an amazing caress, sliding into his body with a surprisingly lightness. Starrk gasped as his hips were gripped, the shinigami taking him with a few quick, erratic, powerful strokes. Then the man behind him stiffened and Starrk cried out as reiatsu suddenly assaulted him. That powerful fluid, infused with both DNA and reiatsu, was what his body craved. The heat abruptly snuffed out as his body accepted what it was given and began the process of rendering.

Starrk's legs gave out and the shinigami had to support him, with a small confused sound. Starrk hardly felt it as he was eased to the ground. This was a dangerous point… when a Beta accepted an Alpha and took their seed, the Alpha was compelled to guard them through the rendering process. That was the brief period when a Beta was completely helpless, their body busy rendering the reiatsu into an acceptable form for the child that would soon be growing. Even if an Alpha did not intend to stay, even if it was nothing but the satisfying of a rut, the Alpha would not be able to resist the instinct to defend the Beta. But Kyoraku was a shinigami. He didn't have that instinct and Starrk lifted his head slightly, his eyes blurry as he watched the shinigami depart. He was going to rejoin the battle and Starrk sighed, curling up slightly and cuddling his guns to his chest. He noticed, vaguely, that Shunsui had pulled up his pants for him. That was nice. If they happened to win, he'd much rather not be found by the other Espada with his bottom bared. Unable to hold back any longer, Starrk fell into a light doze.

There was no Alpha to guard him, but there was nothing he could do about it. The Primera would just have to take his chances.
