50 分钟内 121 次高潮：男性多次高潮的精密控制教程

I demonstrate the precision edging technique that I describe in my Medium article "Advanced Guide to Male Multiple Orgasms: The Precision Edging Technique." This is an advanced technique, which can take you months to years to learn. Since you likely do not have a biothesiometer, I recommend using a cheap rechargable bullet vibrator backwards on the handle-side for the lightest vibrators possible. For the anal orgasms, I am using a wand vibrator on low while doing precision edging with my light vibrators. I've found the rumblier, the better. Toys featured in the video include the Adam and Eve Wand, We Vibe Tango X, a biothesiometer, and a cheap bullet vibe. I use a clicker counter to mark each orgasm.
