Fi is wearing occlusive eyepads, a heavy rubber straitjacket, pvc ballet boots and a tight leather chastity belt. None is necessary to the video, I just thought you'd like to see her dressed up a little.
She is wearing an open-face shiny pvc hood and her mouth is covered with two layers of Hypafix tape. I expect that the shiny hood will help her to dislodge the swim cap but the tape will restrict her breathing.
I start with one swim cap over the front of her face. She blows this off readily. Electrical tape is added to seal any leaks in the tape over her mouth. Although it takes her much longer, she still manages to blow off the swim cap.
How will she cope when two swim caps are used, one over the other?
