A Vintage Electrical Punishment

Description: It's a rather vintage punishment today. i have a vintage electrical device and a sub strapped to the cross. starting on a 4 it doesn't seem to be that painful for the slave. even on the nipples there's not much response. some twitches, especially on the cock and balls. but, 4 is not enough. i tease the slaves cock before i turn the violet wand up to 6. this has more response, and nice sparks on the cock. i can't decide whether to go to a 7 or 8... so.. a 7 and half.. much more cruelty, much more response. much longer sparks. now 8 1/2... it's going to keep going up and up until the slave can take no more.
