I hope you didn't think you were through the worst of it yet slut. Far from it, I want you to take your unit and turn it to it's slowest pulse speed again. And then slowly work yourself up to 75 percent.
Your going to take your pinwheel now and grind it against the top of your cocks head while the electricity snaps and pulses your agonizing genitals. Better not squirm slut, I would hate for those sharp spikes to dig in any harder...
You're going to do this for a full minute slut, understand?
