I'm teaching a masturbation class that you've chosen to attend. You ask me a ton of questions about edging, so I just decide to have you stay later than everyone else. You ask me for a demo, so I sit down and begin using my vibrator to show you how edging works. As I go to stop, you encourage me to keep going. Telling me that you need to see more to understand. I keep going and edging until eventually I go to far and orgasm.
