Karen and Kara urged him through the doorway and into the sweet realm of their bedroom. And something in the dark depth of Clark's mind finally snapped.

He wasn't Superman then. And they weren't Power Girl and Supergirl. Clark couldn't see them as his own blood. Rao, with the scent of their arousal heavy in his nostrils, they weren't even his cousins anymore.

They were the blonde harlots who needed to get fucked.

What little clothing that the girls had been wearing did last long. They may as well have been wearing nothing at all, with Clark's strength ripping the scant fabric from their nubile bodies as if their garb was made of tissue paper.

Lacy bra. Panties. Stockings. T-shirt. He tore them away, revealing the bold curves and sensual lines of their bodies. Great swaths of creamy flesh, their fair skin soft as silk. And warm to the touch. So deliciously warm.

The two blondes squealed and laughed as he made them bare. Even as he loomed over them with his greater height and musculature, Clark still felt outnumbered. Because when he was stripped one down, the other would launch her attack, setting upon him her maddeningly soft touch. Across his back, his shoulders, his arms, down over his abdomen, their hands roamed, shamelessly feeling him up. And where their hands went, their lips followed. Kissing his body. Worshipping him.

Lithe, little Kara was the first to speak, purring into his ear as he divested Karen of her lacy white stockings.

"So forceful!" She giggled, drawing her lips lower to brush over Clark's neck.

Without thinking, he reached out with his thick, muscled arm, sliding it around the younger blonde's trim waist. His hand palmed her pert little ass and he tugged her close, so that she was pressed right up against him. His precious cousin laughed again, a sweet, musical sound. His cock prodded the inside of her thighs, the crown pulsing angrily as it brushed against the soft flesh, drawing so close to the real treasure of Kara's body.

Beside them, Karen gave a hum of appreciation. Out of the corner of his eye, Clark saw the elder blonde lift her arms high above her head in a lurid, provoking stretch - lifting her perfect tits to catch his hungry gaze. With a sigh, she dropped her arms, letting her breasts fall back into place. Clark caught the faint bounce of the flesh, feeling a heat stirring deep in his gut.

"This is the kind of attitude we want to see, Kal." Karen crooned, slinking up to press her body into his free side. A two-prong attack, Clark noted, just like how they cornered him back in the living room.

They thought they were in control, he realized.

Clark inhaled deeply through his nostrils. The sweet scents of Karen and Kara intermingled, sending his heart hammering. But he wasn't put into daze, not like before. Right then, Clark found his mind astonishingly clear. He knew what he needed to do. As a man. As their Superman.

There was a voice in his head then, deep and rumbling, demanding that he divest the two girls of such thoughts. Immediately.

Just like Kara, he reached down with his other hand and palmed Karen's ass. The elder of the two blondes gave a happy hum, squirming excitedly against him as he groped his fill. He felt their touch as well, small hands and slender fingers working upon his hard shaft. They only managed a few eager pumps before he shoved them both onto the bed.

It didn't take much of his strength to send the girls sprawling back onto the pink and frilly cushions - Clark quickly noted then just how girly Karen's room was. The sweet laughter that flowed from their lips roused a hunger from deep within the male Kryptonian. The giggling spurred him on, but he wanted more from them. He wanted them to moan, to whimper, to squeal. He wanted to hear them scream.

"I think we finally got through to him." He heard Kara joke as she writhed upon the bed, drawing her legs close, curling up cutely like the teenager she was.

He caught a quick flash of her pink cunt, so tight and ripe. Clark never found out about any boyfriends - he realized then, there was a very good chance he'd be the first man to have her. The thought had his cock surging with blood, throbbing painfully between his tree-trunk thighs.

Karen chose then to tease him.

"Are you ready to take what's yours? Because this…" She flipped onto her front - committing the sin of taking her succulent tits out of sight - she brought the swells of her perfect ass into view. A juicy, full-moon tush wiggled in Clark's direction and nestled between those plump cheeks he could see the tight, pink folds of her sex. It was glistening for him, warm and ready for his cock. "This is all yours."

Clark made his choice. He would have Karen first. He moved upon her with dark intent. His hands went out, seeking the lushness of her body. First upon her thighs then sliding upwards to her ass. So soft, so warm, Karen's magnificent rear-end demanded attention. Clark gave it.

He palmed it with both hands, squeezing the cheeks together then releasing. He watched the quakes in the flesh, the faint ripples through the softness of her otherwise toned and firm body. Small waves, so quick that they lasted but a fraction of a second, but intoxicating to Clark, the Superman who could see everything. In his chest, his heart hammered, sending boiling blood to the far reaches of his body, spreading the wicked desires that had taken root in his soul.

Clark leaned down and kissed Karen. But not upon her lips - above or below. The smooch was given right to the blonde's delectable booty. He pressed his face into the plumpness of her buttocks, bestowing a deep kiss. Both cheeks, first one then the other. Every bone in Clark's body was crying out, demanding he do more, go further. He grunted against Karen's buttocks, nipping at the soft flesh with his teeth. Beneath him, his cousin let out a sultry moan, wiggling her behind defiantly - or teasingly - right in his face. He pressed more kisses, quick frantic smooches. Then he moved higher, kissing the dimples above her ass, peppering his lips along the line of her back, rising all the way up to Karen's neck.

Now, he loomed over her. His naked and willing cousin. Karen Starr, with her opulent body of proud, splendid curves. She turned her head, casting lidded, blue eyes upon him. No fear that he could see. Nor any shame. All Clark could see was the smoldering heat of desire. She wanted him.

And great Rao, he wanted her.

The proof - his fat, swollen cock - was pressed right up against her ass, just like his face had been. One thrust was all it would take and his manhood would be buried deep inside Karen. Her tight, wet pussy… or her ass. Both prospects stoked something dark and primal in Clark, rousing the savage side of himself he'd only rarely felt before.

But then another idea flashed through Clark's mind. One that not even his darker side could resist. Taking a firm hold of Karen's waist with one hand, he flipped her over.

She gave a cry of shock, cackling with high-pitched laughter as she flopped onto her back. She looked up at him with wide, shining eyes. The look on her face, the lust mingling with pleasant surprise, was a wicked joy to behold. But the real prize was even lower.

Karen's bare bosom - Power Girl's tits. Proud, voluminous swells with the perfect amount of sag - just enough tantalizing heft to let admirers know that they were real. Full, milky globes capped with round, pink nipples which were now pebbled into hard, excited nubs.

Karen shifted on the bed, lifting her torso up with her elbows. The movement sent her tits swaying just ever so slightly, the faintest ripple through the softness of her bust. Enough to make Clark's cock twitch between his legs.

They were perhaps the most spectacular set of breasts Clark had ever seen. He needed to feel them. With his blood hot and frothing in his veins, the last Kryptonian male climbed up onto the bed - straddling the shapely blonde.

"All mine." Clark growled, sounding more beast than man.

The length of his cock found itself nestled nice and snug in the valley between Karen's breasts. With his thumb, Clark pressed his cock even deeper into that lush crevice until he was buried within the soft, milky flesh. It was a perfect fit, almost as if his manhood was meant to be there.

Karen herself seemed to agree, if the smoldering blaze in her eyes was any indication. The smile she wore then was naughty, wicked like Clark had never seen on her pretty face.

With her hands, she pushed her ample breasts together, engulfing most of Clark's substantial shaft between the round globes.

Most, but not all. The head of his cock, thick, swollen, and red, jutted out from the top of Karen's cleavage. Aimed right at the elder blonde's full, glossy lips.

"I knew you'd go for the tits first." Clark heard Kara tease from behind. Somehow, the little minx had snuck up on him. He felt the younger blonde press herself into his back, her modest breasts brushing over the bare skin. Then came her hands sliding around his waist, coming to rest on his stomach, just above his groin.

"Big guy knows what he likes." Karen shot back from below. Clark huffed, feeling her soft lips brushing against his cockhead - as well as the maddening heat of her breath - as she spoke.

"Wrap them around me." Clark growled again, this time commanding. Of course, Karen already had… but she was able to parse that he meant hold them tighter. So she did.

Her breasts came together, creating a delectable tightness and warmth around the bulk of Clark's shaft. The Last Son of Krypton grunted happily, urging his hips forward in short, feral thrusts. Fucking his cock into the crevice between her breasts.

"Yeah… Just like that… Oh, Rao…"

Every jerking thrust sent his fat cockhead prodding against Karen's lips - so plump and soft and perfect for kissing his prick. The busty blonde moaned as Clark fucked her chest, smirking as the crown shot forth into her face.

Every so often, she'd kiss it, planting a lewd smooch on the pride of the House of El before it'd retreat back between her teats, winding up for another thrust. Other times, she'd lick the head, swiping her tongue against it or sticking her tongue out so Clark's thrust would slap his cock onto it. But mostly, she'd just giggle, clearly pleased that she and Kara had finally gotten their dear cousin to break.

Who knew that breaking could feel so good?

"Men all over the world have dreamed of doing this." Karen sighed, tilting her head back slightly so Clark's cockhead wouldn't punch against her mouth. The man above her didn't cease his thrusts, only giving a small grunt of acknowledgment. Karen's smirk grew, a wicked cackle rising in her throat. "Fucking Power Girl's tits. But only you get to do it, Kal. Only Superman can handle me."

Clark let out another grunt, lower and deeper this time. Feeling Kara's lips at his neck, peppering him with sweet, butterfly kisses, only drove him further into his lustful madness.

Superman was there with the girls tonight, but not the Superman that the rest of the world knew. The Superman on the bed, the one that loomed tall over Karen's opulent body, thrusting his long, fat cock into her tight cleavage, was but a twisted likeness. Still the invincible icon, but he embodied new ideals then. Instead of hope or justice, Superman was now a beacon of lust, desire, and savagery. He wasn't a sentinel protecting the world, but a brute taking his pleasure anyway he could.

His thrusts quickened. Every thrust now sent the firm muscle of his waist slapping hard into the underside of Karen's breasts. Clark watched, enamored, mesmerized by the quakes and ripples rolling through the soft flesh. Just as when he had slapped her ass, the suppleness of Karen's body was a delight to behold.

But no sight was so lovely as the image of Karen suckling at his cockhead. Her lips caressing, her tongue swirling, she lavished such delicious warmth upon his manhood that would have sent a lesser man melting. Clark was indeed living a dream - his cock enjoying the delight of Power Girl's big tits and her warm, wet mouth.

And just behind him, the vivacious vixen's younger, alternate self waited eagerly. Watching. Humming. Touching.

"Wow… you look good on your back, Karen." Kara giggled, floating up just enough so she could rest her chin upon Clark's shoulder. Her hands had risen as well, feeling up the solid, broad pectorals of his chest. Her nimble fingers grazed over his nipples. Clark ignored it as harmless curiosity. The younger blonde continued, her voice light, sweet, and teasing. "You look good with Kal's cock in your mouth, too. Almost like you were made for this."

Karen let Clark's cockhead slip from her mouth as she moaned. She angled her face then so that his thrusts sent his cock prodding against her cheek. Her eyes shone brilliantly then, alight with bold, shameless desire. She smirked up at the younger blonde who loomed over Clark's shoulder.

"You'll… get your turn… soon enough…"

Clark caught the edge in her voice. But it wasn't a warning. It was a promise.

It was enough to send him over the edge.

"Good god… fuck…"

It was a surge of pleasure, white hot. Blooming like a supernova deep in his gut. It hit him just as hard as the first one they gave him back in the living room.

His second shot of the evening… sent spewing all over Karen's pretty face… her plump lips… right onto her waiting tongue… and upon her throat… and the great mounds of her spectacular bosom. He glazed her with his seed, rope after rope after rope of hot cum that boiled up from his churning balls. Karen moaned as he anointed her, laughing with joy as he spilled… and spilled… and spilled. Behind him, Kara cooed as she watched his ending unfold, just as impressed the second time.

Even as he emptied himself at the altar that was Karen's perfect rack, Clark felt himself swell with primal pride. The blonde beneath him was an exquisite woman. Not even the blood relation between them could cloud that. And now he had marked her as his own.

It was wrong. Twisted. But it felt right.

And Clark wanted more.

"Nice shot, big guy." Kara In-Ze continued to float, if only to keep herself at eye-level with Clark. Even when he was standing on his knees, he stood taller than her. The younger blonde swung around to his front then, taking up his vision just as Karen began to lick his offering from her face and tits. But Clark was not displeased. Kara's cute, smiling face was just as compelling a sight. There was a youthful innocence in her eyes, even as she reached down to stroke his weeping prick. Her hands were small, smaller than Karen's, and oh so soft. "But I bet you've got another round in there, don't you?"

For the first time that night, Clark gave a genuine smile. His hands went forward, taking Kara's slender, nubile body by the hips. He pulled her close, wrapping his big arms around her narrow waist. She was so slight compared to him, but her lush curves called to him. She was woman. And he was man. They were perfect for each other.

He watched as her cute eyelashes fluttered, her pert lips curling into a pouty smile. His cock remained rock hard, twitching as it was held mere inches from the heat of her teenage pussy. He was going to ruin this girl.

"Of course. I'm Superman." Clark told her, a chuckle rumbling in his chest. "And this next one is just for you."
