Your prudish StepMother is being honored at an event tonight, and your equally conservative StepSister has come home from college to attend. This visit won't be like all the rest, though, because this time, you have a trick up your sleeve. You've come into possession of a powerful laser device that can rewrite the human mind. You've programmed it with something very special in mind for your buttoned-up StepFamily, and today is the day you're finally going to use it-- Right before the event! They're busy getting ready, fussing over their boring, purdish outfits, and when your StepMom leaves to get a necklace, you step into the room and fire up the laser aiming it directly at your StepSister's forehead and the device works immediately, exactly as expected. Fuuka's face goes blank, her eyes roll back, and she loses all control of her own mind. Fuuka begins undressing and mindlessly repeating how she loves to be naked. What a change from just a few seconds ago when she was trying to cover up her massive cleavage! Her boobs have grown in college, and she gives you a good, long look as she strips in front of you. She's already completely naked, eyes wide and obedient when your StepMom comes back in the room and, completely predictably, panics. She rushes around trying to cover up your StepSister, and when she turns to you to order you out of the room, you take your chance and point the device right at her head, too. The laser takes a second this time. Your aim is a little off, but quickly, your StepMom's mind submits to your reprogramming. As she stares, eyes rolled back, your mindless StepSister begins undressing her StepMom for you while she just repeats the same vacant mantras about being naked and loving to be on display for you. Your program not only makes them love being naked, but it makes them incredibly horny with no sense of right or wrong, so they immediately turn toward one another and start mindlessly kissing and groping each other. You sit back and enjoy the show until they start to awaken and realize what's going on. Confused and horrified, they try to cover up, and you think you're going to need to use the device again, but the moment they see each other's bodies, they're quickly distracted and start kissing and touching again. Their horny brains can't stop them now. As your StepMom fingers your StepSister in front of you, they notice you're hard and decide you need to join in. Of course, with an invitation like that, you can't decline. They drop to their knees and mindlessly and obediently suck your cock before taking turns riding you as your obedient, slutty slaves. Even after you've all fucked, the mental mind fuckery is still in effect, so now, you want the world to see your StepMom and StepSister as the slutty whores they really are. It's time to test the strength of the programming your device created. You pick new outfits for the event, skimpy lacey lingerie for your StepMom, and a slutty bra and panties with garters for your StepSister, with a matching collar and leash for good measure. They're both so excited to be displayed for everyone at the event and they can't stop talking about how many photographers will be there, and how they want to be seen and maybe even fucked by everyone there! Your StepMom grabs the leash, and it's time to go... Tonight, will be one to remember - at least for you.
