In an apocalyptic future, the Powers siblings were among the few survivors still standing against the dictatorship of Kang the Conqueror. After destroying one of Kang’s recon robots, Katie returned to her brothers who were fucking wildly. Actually, it was Julie’s turn to answer the security alarm, but since she had already started getting fucked by Alex, Katie offered to take charge herself.

Luckily, Katie arrived just as Alex was about to cum, so after filling Julie’s pussy with his sperm, Katie took it upon herself to clean the stains of his seed with her mouth, preparing for her turn. The Powers siblings used to have incestuous sex every day so they could recharge their powers. Although it was all for work purposes, Katie had developed a great urge to be fucked by Alex’s huge cock for hours.

To her disgrace, Alex was on the verge of climaxing from all the sex she had with Julie earlier, so it took only a couple of seconds for him to cum inside Alex. She wasn’t satisfied with this, so with her vagina dripping, and her body giving off electric shocks, she jumped back on her brother’s cock, begging for him to keep penetrating her. Hesitant, Alex decides to resume their penetrations.

At that moment, the brothers are interrupted again by the alarm. Without even getting dressed, Katie goes to the entrance of her home, ready to kill whoever gets in front of her, until she finds out that the intruder was her lost brother, Jack. Although the Powers were excited about the return of their sibling, they decided to scan him. Unfortunately, Jack was locked in his armor, and they needed to recharge in order to get him out of it.

Without many options, Katie decides to use her powers to try to energize him. But because of her exhaustion, the youngest of the Powers was weak, so her brothers decided to fuck her together. While Alex penetrated her pussy, Julie used a large dildo to fuck her ass hard. Little Katie had never felt so close to her relatives as at that moment when she felt them filling her insides with their members.

After several hours, Katie obtained the power necessary to give energy to Jack’s armor. After so long, she could hug her beloved brother again, obviously she was not going to waste that opportunity to feel his member again. An idea that did not completely convince Jack who would now have to drain all the energy of his younger sister through wild sex.
