Punish the tied slave tail (glans) and testicles with the electric fly swatter. Of course, I'm gagged with a penis gag. You have to hit very hard with the fly swatter so that the electric shock comes and sometimes it comes and sometimes not, so a very cool feeling but without a gag you would scream the whole neighborhood together ;-) Of course, it would be much cooler if someone would do that to you, but better than nothing. If someone else does it, he or she would of course have to tie me up properly so that I absolutely can't defend myself anymore.
