Option 1: Daughters of Krypton

Clara Kent, alias Superwoman, gasped in pain as an enormous, craggy fist hammered into her diaphragm. The freezing breath that she'd been building up billowed out into thin air, nothing but a harmless cloud that quickly faded into nothingness as it was driven from her by the **** of the punch. The fist's owner snarled as her white-clad cousin's fist smashed through the creature's hide and cracked the ultra-dense bone of the vertebrae beneath, before whirling around and jamming two fingers into the blonde's puffy slit. Its arm pumped twice in quick succession, each time with enough **** to shatter concrete, then pulled back and swung in an uppercut that sent Clara's fellow Kryptonian spinning wildly through the air with a heavy blush on her cheeks - the damage to its spine not seeming to hinder it in the slightest. The whole exchange had lasted maybe two seconds, and was depressingly indicative of how their battle had gone so far.

The two superheroines had been on the back foot from the moment they'd arrived to find the hulking thing rampaging through Metropolis, smashing everything in its path. At first, things had gone well; the beast had immediately stopped murdering the mundane humans around it in order to attack them instead, and they'd been able to lead it back into areas it had already thoroughly wrecked. That was about the only thing that had gone to plan, though. It was smart, fast, strong and above all tough - first crippling and then killing blows were shrugged off in seconds, any attempt to strike it with anything less than their full strength might as well not have happened, and even the wounds they had opened up on it didn't seem to be slowing it down much. Worse was its fighting style, a bizarre mixture of traditional hand-to-hand combat and - for lack of a better term - weaponised molestation.

And worst of all? It was effective. Both Clara and Karen were well-used to the fact that criminals, invaders and the generally immoral were just better endowed and more skilled than their male comrades, but neither of them had ever been exposed to it quite like this. Nobody had ever been able to get past their Kryptonian physiology and make them really feel their efforts before - but the way this creature's fingers filled their holes, the way its slaps made their curves jiggle... Was it any wonder the pair were already soaking wet, even despite the circumstances? Something about its presence - about the sight of its cock - seemed so oppressive, so powerful, that it was clouding their judgement on what was or wasn't 'appropriate' for such an encounter.

The two Kryptonians and the freak of nature they were fighting traded a dozen blows over the next minute. More craters were punched or kicked in its hide, skin seared off by heat vision or shattering under waves of unnatural cold, bones creaking and cracking under the pressure of superstrength-empowered pins and holds. In return, the heroines were ravaged. The wake of its punches shredded their costumes while the blows themselves knocked them through the ruined shells of buildings and vehicles. Open-handed slaps sent bra-bursting busts and dumptruck asses jiggling and bouncing wildly with every collision. Colossal fingers stretched vice-tight pussies and assholes to an extent that neither had ever experienced, and withdrew before the sensations could do more than drive their 'unwanted' arousal even higher.

Superwoman moaned as her opponent brought his palms together and delivered a clap that mashed her tits together, the pressure enough to make her already achingly-hard nipples throb with need. Power Girl attempted a strike to the base of his skull, but before the blow could connect he shifted to the side, leaving her fist to sail harmlessly through the air and planting Superwoman's face firmly in her cleavage - and snapping the last few threads holding the chest of her leotard together in the process. A stinging spank landed on her ass as she and her unintentional smothering 'victim' barrelled past him, the extra momentum sent the pair of them rocketing into the ground, the blonde's tits pressing down on her black-haired cousin's face as they gouged a trench along the street.

Clara blinked sluggishly as the silky-soft prison around her head abruptly fell away, revealing the beast holding a thrashing Power Girl by her hair. He dragged her down until her face was level with his waist, wrapped the other hand around the base of his half-hard cock and-

WHAP!

Power Girl's expression morphed from snarling outrage to dazed confusion as eighteen inches of bicep-thick meat slammed into it. Her jaw worked soundlessly as-

WHAP!

Confusion shifted to drunken dizziness as she was struck a second time, now by almost two feet of throbbing cockflesh. Her vision swam from the **** of the impacts, a small part of her mind still trying to focus before-

WHAP!

A full twenty-six inches of monster dick, hard enough to blunt a buzzsaw in an instant, crashed down and turned her confusion into brainless bliss. He lifted the quivering, gushing woman by her hair and casually tossed her through the front of a building - dozens of tons of concrete and steel burying the hopelessly cock-cussed blonde - before Superwoman's fist slammed into the back of his head and caved it in.

She floated there for a second - bodysuit in tatters, chest heaving pussy aching to be filled - waiting for a counterattack, but none came. Slowly, she shifted around to his front, trying - and largely failing - to keep her gaze from locking onto his massive erection, before reaching out and pushing him over. Before the dust of his collapse had settled, she was digging her cousin free from her impromptu prison, tossing aside slabs of broken concrete and chunks of rebar to reveal Power Girl, three fingers buried deep in her dripping honeypot and her other hands groping her tits hard enough for the pale flesh to bulge slightly between her fingers. Clara was about to reach down and pull her free when she felt the air shift behind her and a massive hand closed around the top of her head.

In an instant he had her face practically buried in his colossal grey nuts, grinding it against his churning, throbbing cumtanks. She had - just barely - been able to push through the arousal brought on by his musk before, her mind now recognising that it hadn't just been the novelty of properly feeling his hands mauling her body that had made her so incredibly horny as they fought, but now there was no escape. So close to the source, and after getting him so worked up, the pheromonal cloud was inescapable and unstoppable as it was **** up her nose and down her throat - it filled her nose and smothered her tastebuds, drowning out everything but the scent of a pure, unadulterated Alpha. Superwoman, as the rest of the world had previously known her, died almost instantly - smothered under a tide of lust just as surely as Power Girl had had any truly selfless thoughts of heroism cockslapped clear out of her head.

He reached down and wrapped a hand around Power Girl's waist, the dick-addled woman's powers of flight unconsciously helping him to lift her as her fingers finally left her cunt, her hand shooting up to join the other in groping her tits as she threw her head back and wailed in pleasure. A wail that only grew in intensity as he lined her gushing slit up with the head of his cock and yanked her down it, filling her to the brim instantly and dragging her self-induced orgasm to even greater heights. Unlike the humans he'd used before, his new Kryptonian cocksleeve simply refused to succumb no matter how hard he jerked himself off with her, the heroine-turned-fleshlight simply screaming for more as he thrashed her up and down his shaft for the next few minutes - a subjective eternity to the shrieking, begging slut he was skewering.

Power Cunt, as she was rapidly coming to think of herself, couldn't be happier with the arrangement. Sure, getting her pussy resized by her new god was steadily frying her brain with the intensity of the pleasure it induced, but who cared? She certainly didn't, even as her personality and memories were forcefully blended with her current musk- and rut-induced haze, tainting every moment irrevocably with a lewd hunger for her master's cock. By Rao, she'd been so stifled before he came along! As soon as he was done using her and moved onto the next set of holes, she was going to get her costume redone to what it always should have been - starting with a cleavage window below as well as above, so he could use her breasts immediately when they next encountered each other!

Oblivious to her cousin's own thoughts, Superslut's tongue was hard at work cleaning her god's nuts. Her own mind had succumbed to his power even faster thanks to her current position as his personal musk-rag, her senses drenched with the scents and sounds of his virility. This was a creature that could fulfil her deepest, darkest fantasies - that could fill her with children and restore the birth-species she'd never known through sheet sexual potency. His balls began to pulse against her face, rattling her skull as he drowned his current fucktoy's eggs in his treacle-thick spunk. She felt, more than heard, as he pulled the blonde off of his cock and tossed her aside once more, the cum-bloated bitch no doubt oozing the dregs of his load from her gaped pussy. Clara didn't care about that, though, because now it was her turn.

He didn't so much enter her as smash her open, her abs vanishing into an obscene cockbulge and her mind whiting out from the intensity of his first thrust. She was vaguely aware, through the rhythmic, inexorable pounding of her walls to fit his shape, that she was screaming; screaming her pleasure, screaming his praises, screaming for more, all picked up word for word by the news helicopters circling over head. Aboard the circling machines, their all-female crews - for there wasn't a man that didn't find his nerve failing at the thought of approaching the beast - tried their best to stay steady. Moans, sighs lewd language crept into otherwise staid reporting, pilots fantasised about gripping an entirely different form of stick, cameras tracked every twitch and quiver of the Woman of Steel's body as they documented the first true defeat either of the pair had ever suffered.

With one last roar of triumph, a flood of genetically-engineered jizz blasted past Clara's cervix and packed her womb, stretching her body to the limit as he poured more and more of his seed into her. Faster than any of the panting, blushing women circling high above could track, the beast was gone; all that remained were Power Cunt and Superslut, their lush bodies completely exposed, their bellies swollen obscenely. Neither stirred as screams and roars began to echo from further into Metropolis's heart, except to stroke and squeeze their own bodies.

Doomsday's destruction of two of Earth's most powerful defenders - as opponents, as symbols, as the heroines they once were - was complete.

Option 1: Doomsday's rampage through Metropolis continues, leaving a trail of broken women behind him. Who's among them?

Option 2: Supergirl seeks Doomsday out, seeking to avenge her fellow Kryptonians.

Option 3: Follow Superslut and Power Cunt as they succumb to the corrupting influence of their lust for Doomsday.

Option 4: Something else! Whatever you want, write it or suggest it.
