Was it "The Odd Angry Shot"?Years ago, I watched a film about Australian troops in Vietnam. It was their padre's birthday, and they presented him with a wanking machine, for which he was thankful.
This consisting of a shoe-box, with a wire coat-hanger threaded through, and bent into a handle on the outside. There was a hole about two inches diameter at one end. The inside had a cupla feathers attached to the wire, and the user can attain maximum effect, by inserting tool into hole, and winding the handle.
I daresay the Americans and even the Vietnamese had their own similar devices to beat the loneliness and boredom.
With the Padre's classic line of "fellas, this is without a doubt the best wanking machine I've ever seen"!
I don't remember the name, but the padres defo said that. I have only seen the film that once, in the mid-80s, back when I had ear and nose rings, not grenade-rings, and the only green I wore was the streak of hair down the centre of my shaven head.
A friend of mine told me that 'Fleshlights' are super, but they require a diligent cleaning regime otherwise moulds could develop, leading to cock rot. As for cock rings, the ones with a magnetic quick release are the safest & obviate the possibility of facing the angle grinder.
