I only recall being asked for waterboarding once - and I did it. At as the time we had a converted laundry room that was used for heavier scenes. It had a drain in the center and we had put a metal field operating table in there that could be cranked up or down or tilted at either end. It was perfect. We tied him to the table, inverted his head and then put the towel over his face and then drip, drip, drip. It was new to me too and although I read and watched videos to prepare, I was still tentative. He didn't last long and never wanted to do the scene again. (He was a regular that often thought up extreme torture/interrogation scenarios.) It's a shame because I really enjoyed it. The visual was amazing.

On another front, one of my guys did a session with a Domme visiting his town. He was curious about drinking golden and she gave it to him - in mass. He said it was like being waterboarded with urine. It was not a scenario he wanted to repeat. lol
