My husband and I enjoy a master/slave relationship as a prelude to sex. I have metal rings in my labia, metal rings in my nipples and a metal stud thru my tongue. Nick did all my piercings himself. We are both 43, married with 2 grown college sons that don't live near us. We have a room in the basement that has all the equipment we use in our special form of foreplay. There are metal clamps, metal chains, metal weights and Nick's pride and joy, a battery operated devise that gives out electrical shocks. When the wand is near any of the metal or my skin, a viisable blue electrical arc is emitted from the wand. Nick immobilizes me with hand cuffs, ankle cuffs and wooden bars. I am standing with my butt against a work bench. He clamps the chains to my labia and boobs and adds weights to stretch my boobs and labia toward the floor. He gets his electrical toy and brings the wand near enough to give me a sudden shock to my boobs, pussy, thighs, butt and tongue He doesn't gag me so I can scream out if the pain from the weight or the shocks become unbearable for me. The idea is to see how much pain I can tolerate without screaming out to stop. I have developed a very high pain threshold over time. Nick & Nancy B.
