Something shocking

   She stopped, suddenly. “But we can’t just do the same thing over and over again, now can we? After all, what’s life without a little bit of variation?” 
      She walked around towards my head again. “I think for this, I would like you to be a little surprised. Hold still.” With that, she reached into her pocket and pulled out a collar. She quickly slipped it around my neck, and then clipped it to yet another ring in the floor.  My head was now trapped facing upwards. And then she passed out of my view, leaving me with no idea as to what she was doing. 
   I heard a little rustling, as if something was being drawn out of a bag. A second later, I felt something round and moist applied carefully to the inside of my left left, just below where her finger had been a few seconds ago. I tried moving the leg, but just like twenty seconds ago, had no success. There was a slight giggle from my tormentor, and then I felt another being attached to my right, in the same spot.
    “You might get something of a charge out of this…” 
      And then, I felt a violent electric shock go through my entire body. And yet, because of the placement of the two wires whose circuit I was completing, although my entire body was in pain, the corresponding tingling in my vagina was almost pleasant. It was probably the most curious feeling that I had ever felt in my life. 
   The charge stopped, but only just long enough for me to catch my breast, and it began again. There again was the pain in my body, and the tickling between my legs. When it stopped I almost wasn’t sure whether I didn’t or did want her to turn it back on. 
    Not that it was my choice. She turned it on again, for longer. And then again, and again, continually pausing and then starting over. I may have orgasmed at some point. And then, finally, it ended. I could feel tears running down my cheek. 
  But that wasn’t yet the end of my night...
