Hi,
Have just tried using my TENS machine on one of my 24 yo friends with the most incredible results.
Using 4 Steel Cockrings in place of the sticky pads, we placed one around his Testicles and the other three at the base, mid shaft and below the coronal ridge and with a urethral sound inserted, we set to work.
Lee's Penis twitched, throbbed and swelled as the different pulses and bursts kicked in and about 10 minutes in to the 20 minute programme, his Penis was waving and bobbing with no manual stimulation.
He said the sensations of the Urethral probe was awesome and could be felt the entire length of his Penis, Prostate and Rectum
Lee was lathered in sweat and was really moaning with pleasure when he suddenly had the most powerful orgasm I have ever witnessed.
The Urethral probe was expelled with speed and velocity as he shot many ropes of cum as his Penis bounced in all directions.
I turned the TENS off about 30 seconds into this and when it finally stopped, Lee was still bucking and convulsing with his Penis still moving about wildly.
He remained very erect and it took several minutes before he could remove the rings and clean up.
This was the first time we have used a TENS machine for estim rather than a sextoy version with anal Plug.
I have been a Playdoctor for many years and have 40 plus years of Cock fun and never seen anything so amazing.
Can't wait to see Lee again or to try it on other (un)willing patients.
