My two bimbo sisters are obsessed with partying and dumb jocks. Its all they ever talk about when they’re not insulting their nerdy brother… me. But being smart has its perks, I made a nano-bot conversion chamber out of their closet. Once they’re turned into obedient robots, Ill be able to do anything with their sexy bodies anything I want. This is what they get for making fun of me all of those years. The trap was set, I watched and waited in the bathroom as the brats got ready for their party that night. They were getting undressed – I finally got to see them naked! But as I was shifting with a raging boner in my pants, my sisters caught me. They called me a pervert and made fun of me before turning to find some shoes to go with their dresses in the closet. The doors slammed shut and my machine fired up with them inside. It worked! My sisters were trapped in that chamber until the process was complete. A few minutes later, the doors opened back up. My sisters walked out, utterly transformed. The nano-bots had replaced their clothing and everything under the skin. Even their movements were different, calculated. They stood in front of me awaiting commands from their master. Perfect. Now is my chance to use them the way they deserve to be used. First, I wanted to test the robots’ responsiveness with a few simple orders. They were prompt when commanded to take each others tits out and spank one another. I then ordered them to rub their little robo-pussies and to enjoy it. Just watching them masturbate and hearing them moaning got me rock hard. I couldn’t wait any longer. I had to feel my robo-sisters’ mouths all over my cock.
