A great addition to my collection of cock stimulation gadgets.
Very well made and very smoothly machined, which is just as well for something that is designed to slide into your cock.
My cock can accommodate an 8 or 9mm sound, so I bought the medium sized plug, which I use with a 2mm conductive loop connected to a Helix power box via a bi-cable.
I produce a lot of precum so I withdraw the plug from time to allow the precum to flow out of my cock.
When I finally ejaculate, the plug is forced out of my cock by the power of the cum, which is a great feeling !
