I was actually feeling proud of little Sammy for how diligently he has been working on his science experiment but then I discovered that he was motivated by something other than academic ambition. The dirty brat was trying to build a mind control device and he planned to secretly test it on me for his own entertainment. I knew from the way he was always trying to look down my top or up skirts that it was not going to be some cute show where he made me quack like a duck. I was proved right when he finally snuck up and blasted me with whatever gadget he had been constructing. Too bad I had already sabotaged it. I pretended to be totally under his control at first and sure enough, he ordered me to strip within his first few commands. He barely even tested my obedience or awareness before he was grabbing handfuls of my tits and proclaiming himself to be a genius. I let him live his perverted dream of having his step-mom as a mindless sex doll for a little longer before I snapped him over my knee and into his nightmare. From thinking he had absolute power over my body to begging me to stop spanking his bottom in less than two minutes. At least he will have some memories of seeing me naked to comfort him during the long months of chastity ahead.
