Well, I have both a 250,000 volt and 500,000 volt stun gun. ( No shit, i ordered them from some spy magazines) I think the ones police use are 250,000 volts. Honestly you cant tell that much of a difference unless you hold it on for more than a second or two. We have only used them a couple of times and my wife recently grounded me from them because I got a little carried away. When I would use it was when we were doing it doggy style usually. .... I would often have a towel around her neck with one hand tightening it to deprave her of oxygen and before she would cum, I would pull out and she would start squirming for more, so I would zap her ass.. Just really quickly. enough to knock her to her stomach and stun her but not enough to really HURT. It mostly just paralyzes you quickly... tightening ALLLLL muscles. She would usually limit me to two or 3 shocks and then I would finish her off... The Stun guns I used were handheld, fit in your hand, not the big cattle prod style. Anyways, they sometimes leave a mark that looks like a small burn for a day or 2.
She took them away cause I would get bored and chase her around the house zapping it at her, just playing. We would both be laughing our asses off but she started being a pussy about it and took them away...
It sucks cause when my friends and I gamble on dumbshit, like football, we dont want to take each others money so we would bet STUNS... ( not in a sexual way)
Stun guns are good wholesome family fun.
