I take advantage of the vise grips holding Nina’s cunt open to zap them with the poky-zappy thing. They struggle more-or-less-successfully to hold still, even while I’m using their extra exposure to seek out the most sensitive spots. We both get turned on, but once I start fucking them with my fingers it becomes apparent that vise grips on one’s outer labia can be painful when jostled. They don’t especially get in the way of fucking with the steel rod, though.
