As soon as you see my body, your cock hardens, and your IQ drops a few points. A boner is the brain's biggest enemy. And when I tell you to stroke, you don't think twice about jerking that cock. Why would you? You want to edge for me. It feels so good that you don't even notice the brain cells draining and depleting. The thoughts clearing away into nothingness.  I tell you to stroke harder, and you eagerly obey. Oh, it feels so good to goon for me when you're riding the edge, when I'm in the zone and you're right there with me. Stroke FAST! HARD! As your hand pumps uncontrollably up and down, your mental power attenuates -- one dripping, drooling, dumb stroke at a time.  You don't realize what's happening until it's too late. Your hand is gripping your cock, reflexively tugging it up and down...do you see how stupid I've made you with all this stroking? What a mindless masturbation zombie you've become? You try to consider the question, but it's just too hard to think. All you hear is the encouraging tone in my voice; all you see is my sexy body and the smile on my face egging you on; all you can do is keep stroking yourself stupider still. It's so easy to rob you of your last remaining brain cells when there are only a few of them left.
