field telephone
A field telephone is a communications device used by cadets and the military to communicate with nearby military units -- can be used to administer electric shocks to a guy's tits, cock, balls or asshole to make him talk or just for fun.
We were out doing field exercises, and some of the other cadets grabbed me, held me down, and attached the electrodes of a field telephone to my tits, genitals, and asshole and turned the crank, sending me a "message"!
field telephone
A field telephone is a communications device used in the military to talk to troops in out-lying areas. It is used in some electro-sex sessions to send a "message" to the recipient. Electrodes are attached to a guy's cock & balls, his tits, and maybe his asshole. When the phone's crank is turned, it sends a jolt of electricity to wherever the electrodes are attached on a guy's body. The faster the crank is turned - the bigger and longer the jolt.
When we were out camping, some of the guys wanted to practice using a field telephone and they it used on me -- on my nuts, cock, tits, and butt-hole - they really cranked me -- it hurt, but I was having dry-gasms before they finished!
