Fighting for dominance.

Brit cackled in hot-blooded elation as the gray skinned monster grunted and released her to hobble back a few steps.

That was what it was all about, that was what she lived for! The heady thrill of the fight, the skin-tingling rush of facing danger and the heart-racing prospect of coming to blows. All boiling inside of her like a witches brew and super-heated by a powerful rush of arousal that had hit her like a Mac Truck soon after boarding the drifting space-vessels.

"All you self-important assholes forget how fragile your precious family jewels are." She taunted, casting aside her useless laser rig and tackling the gray man-thing to the shiny corridor floor with the impressive impact of two hard naked bodies colliding. "As though that big swinging dick you're so proud of isn't the most **** part of your entire body."

Sure, Brit might have been able to blast this hugely hung monster out into the vacuum of space with the mining auger but her hands had grown too large to handle it with any finesse and, frankly, she was spoiling for a good ol' fashion brawl right now.

"I'm going to make you kiss them better before we are done, girl." The monster wheezed, wrapping an elbow up under her thigh and throwing her aside as she tried to pin him with her new-found weight. "Don't worry though, you're going to love it."

The male fucking ego wasn't lost on this over-inflated asshole was it? Brit didn't have anything against a bit of spicy sausage, growing up between the outer periphery colonies and making a living patching up corsair vessels for some of the nastiest pirate scum in the galaxy meant that a girl couldn't be too choosy when she fancied a little slap and tickle. But any man that wanted a slice of her cherry pie had to pay for the privilege with blood and sweat.

"I'd say I'm enjoying the display you're putting on down there..." Brit snorted as she rolled to her feet and dropped into a low crouch. The tops of her knees pushed her pale ballooning tits up under her chin and her balance wobbled for a second. "But we both know it's all for show, right?"

He began to circle her and she waited until he was right where she wanted him.

Sorry Tasha, maybe put up a fight next time, instead of fucking the target. She thought as powered into him again, just as he stepped in front of the prone form of the semi-conscious, cum-drunk co-pilot. Those white-collar criminal sorts were always a bunch of soft lazy sluts. Try getting arrested for raiding an armoured Tuscon Corp freighter and blasting the tactical response crew to atoms instead of data theft and see how they treat you in the mega-corp corrections facilities.

"You're gonna eat those words and a whole lot more real soon." Her titanic opponent retorted, catching her charging bulk and grunting a little at the effort but not tripping ass-over-tea-kettle on Tasha as Brit had hoped. "Can't you feel it though? Can't you taste the first notes of what you are becoming already?"

She could, by all the celestial spheres Brit could feel... something. It was like getting high on synth-stims without the dry-mouth and muscle twitches. It felt like every cell in her body was bathed in brilliant starlight and pure Klavaxian hyperfuel pumped through her veins. Brit felt amazing and the need to fight or fuck was so overwhelming that she didn't know if she was going to spit blood and or cum messily down her bare bulging thighs.

It had started not long after boarding. She had split from Suki as planned and headed straight for the engineering bay of the first courier class vessel ready to gut the ship of any engine parts or tools she needed or would fetch a good price in trade. The strange smelling mist hadn't bothered her at first so Brit had ignored it, focused on executing the classic smash and grab job as quickly as possible.

"You talk a big game for someone who's about to get their balls handed to them." She half-growled half-giggled as she slammed her heel down into his in-step with a satisfying crunch and followed it up with an heavy elbow to the solar plexus. "And the last pair some filthy fucker tried to feed me got them bitten clean off."

It was true and then it had taken all five of the screaming bastard's fellow guards to beat her half to **** before she spat the bloody mouthful back out. Not one of the guards or any of the male inmates dared touch her after that, which was a shame because some of the bigger convict brutes looked like they might have made for an exciting spot of rough and tumble. If they only had the nutsacks to take her the way she wanted.

Brit danced back grinning with her fists raised, waiting for the monster to double over or puke up his guts. Her nethers fluttered when he just snarled and narrowed his gunmetal eyes at her.

"Done playing yet, Girl?" The granite-skinned goliath rumbled, and Brit would swear she felt her engorged clit reverberate along with the deep bass tone of it's voice. "You have grown but you are too new to your strength to match me... yet."

She had grown, Brit didn't understand why she had burst free of her already over-taxed coveralls or what was happening to her thrumming, super-charged body but it didn't matter anymore. Every part of her was ablaze and the solution for it, one way or another, was right in front of her. Brit shook off the sweat beading her forehead and let her face split into a rictus parody of a Cheshire grin.

"You think you got what it takes, fucker? Then stop pussy-footing about and prove it!"

Adam grunted as the strapping naked brunette showered his impossibly burly form with punches, kicks and every dirty fighting trick he had ever heard of.

When he lowered his arms to grapple her firm supple physique, she clawed at his eyes, nostrils and mouth. When Adam raised his guard, the imposing pirate hellcat pummeled his ribs, stomach and kidneys with thrown knees and elbows. The burning in his back was soon matched by scratches, cuts and bruises all across his stony flesh.

But despite her reckless onslaught, Adam could smell her growing arousal and she stank of vicious, cunt-dripping excitement.

"Come on you, big gray bastard. Don't you fucking dare hold out on me." She jeered as he twisted away from another snap-kick aimed at his groin, nearly slapping her foot away with his steely swinging tool. "Give me everything you've got!"

The old Adam might have admitted that her speed, fury and sheer grit were more than a match for his limited defensive training. The old Adam might have backed down and tried to de-escalate the **** with calm logical words or bargained his way out of the situation.

But the old Adam was weak and dead and gone. That Adam didn't deserve to claim a mate this fiery and indomitable and irresistible. The old Adam didn't have a beast bellowing inside of him to break in this wild bucking broodmare and take her for his own.

The new Adam was ready to beat her soaked pussy into submission with his giant battering ram of a cock, if that was what it took. Because that was the right and lawful way of things now, in accordance to the most ancient law in nature. The biggest and strongest survived and passed down their alpha genes to their young so that they could do the same. It was the never ending cycle of evolution, struggle and domination.

She was all piss and vinegar but for all her relentless **** she hadn't realized that Adam had been slowly corralling her into a corner between the unyielding bulkhead and a sealed airlock. She had nowhere left to go, no more room to dance around him.

"You want it so badly?" He roared, ducking a frenzied hay-maker and crashing into her soft yet toned fighting femininity with all his superior weight and mass. "Better brace yourself, Girl. You're about to get it!"
