This has to be one of the more ***** things I've ever seen. Wow.
There are many things I understand but do not do myself for erotic stimuation. I have seen people use sounds, catheters, and needles but this is extreme. I am glad he is using what appears to be sterile technique but the risk of infection in a non-sterile enviroment is too great. Good luck - I have no idea what you could possibly do next to feed your fetish.
What is he doing?
good question...WTF is he doing?!?
