One problem I have with my BDSM bed with the gynaecological stirrups, is that when my victim is helplessly bound with legs secured wide apart, the victim is flat on his or her back. So bitch-boy gets to feel the pain of the ruler smacks or nettle pouch on his clitty, or the pegs being pulled from his scrotum, BUT he does not see this happening. How much better if he could see all the preparations and action, (or worse for him!), if he could see his clitty being made hard, see the pouch full of nettle leaves approaching and see it pulled over that stiff little clitty. And then while he squeals and whimpers with an amusing tone of panic, see a cruel, eager hand squeezing and moving all around and squeezing again and again to maximise the leaf to skin contact points. I have no doubt this would deepen the victims suffering, and awe of his/her tormentor.
I have noticed that very well equipped dominatrix actually have a camera and flat screen combination to overcome this. I think the goggles are better than that. They ensure the slave is not distracted looking elsewhere.
I am assuming the goggles can be connected to a camcorder. I am thinking if I go ahead with a purchase of goggles, I will set the camcorder zoom to be able to take in the face of the tormenter as well as the genitals of the tormented. I think seeing the relaxed, merciless, sadistic bliss on the face of the tormentor as well as the activity of torture, will be ideal. I also know that would mean bitch-boy would see Governess Lexi and I passionately French kissing while, for instance, the pouch is on the clitty. As we always do.
