You've signed up to participate in an experimental study in a lab for sexual studies. It is your first day of the experiment. Today, we'll be testing how you respond to various kinds of electrical stimulation. The sensations will be intense, and you may reach the point of orgasm several times. Once we begin the experiment, we can't stop - even if you get overstimulated! Most of our subjects cry, beg, and cum non-stop for hours. It will be quite the experience for you. Now, let's begin, shall we?
