The swatter doesn't hurt as much as startle and the flashes are more audio/visual than shocking - but . . . every so often you can get an actual shock that really sort of takes your breath away so if you experiment make sure you keep it below the waist. At least until you have become familiar with what to expect. i haven't done much in this type of play for a while.
I really liked the part where you put your balls on the racket! Why doesn’t it shock more? Does it hurt a lot? I’d like to try this but I’m scared! Nice vid!
