No longer withholding back, Superman and Faora's immense strength made the underground cavern quake. For a brief instant, Superman's ever-present responsibility surged from the orgasmic haze clouding his mind; making him ponder the posibility of his rough mating session with Faora causing powerful earthquakes in the world above. But, as mentioned before, it was only a brief thought. It didn't took too much for his increasingly primal nature to take hold again;, leaving him as a primal shade of his former self, bent only on breeding the bitch in front of him.

"K-Kal, stop!" Supergirl pleaded. Her voice was cracking, as she was using every trace of self-control in her body to resist the urges that were now assailing her. Kara and Power Girl both were squirming and trembling like jelly, trying their best to not give up to the arousal that surged through them.

"Ungh! Ungh! Can't...!" Superman panted back as he gripped Faora by the hair and pulled her head back, as to establish his dominance over her. The raven-haired beauty purred in response, then let out a thunderous scream as both the Man of Steel and her climaxed at the same time.

Faora fell to the ground, panting and huffing as the excess of Superman's hot seed spilled from her womanhood. There was a pleasured and exhausted look in her face, and her smile, almost feline in nature, made Supergirl and Power Girl disgusted. Slightly hunched in a caveman-ish stance, Superman heaved and his body glistened with sweat under the dim, red light produced by the lava rivers. Power Girl couldn't help but stare at his still erect manhood; dripping wet with both Faora's womanly juices and his own cum. 

There was an almost maniacal look to him, something that made even the cocky and arrogant Power Girl shiver with animalistic fear and something... else. The blonde bombshell could resist no more, and being overwhelmed by the influx of kryptonian pheromones in the air, lunged at the Man of Steel; turning around and presenting at him like a bitch in heat. Superman nodded with a soft grunt, then, grabbed Power Girl by the hips and started fucking her raw. 

Supergirl was doing her best to resist, but even with her hard, self-imposed morals; soon fell on her knees and started fingering herself, ignoring the tangle of blonde curls covering her crotch or how her fingernails had elongated and curved to the point of resembling Cheetah's claws.  The young heroine's thoughts were quickly reduced to a primitive nature, overwhelmed by whatever was happening to them and she was no longer viewing Superman as his older cousin, the greatest hero and defender of Earth. No, she was looking at him as a very desireable mate, and she had the sudden need of bearing him strong children to perpetuate their race.

After finishing with Power Girl, the Man of Steel noticed the eager young female in front of him, and lumbered towards her; gripping his cock in his right hand and grinning almost viciously.
