Example of extreme stimulation. He obviously had a secret fetish fantasy in which he would be very slowly strangled to death, while also simultaneously being raped rough as he would be dying. Well, his fantasy came true,,, The counterweight method he used is actually very popular amongst practitioners of erotic asphyxiation. Since (as they wrongly think) it is a lot more safe. Because less chance of damaging your neck, without the need of full body weight suspension by the neck and the hanging/strangulation effect can last significantly longer, as oppose to just a few seconds in the full body suspension hanging, before the danger of passing out. But as they do it more often, they become more careless. Wanting to prolong it more and also increasing the weight of the counterweight. All so to experience even more powerful orgasms. But it is all just a game of "Russian Roulette". Some can die at first try. While other years later. But with each try the chances that something can go deadly wrong will only be increasing. And sooner or later something is guranteed to go wrong. Resulting either in death, paralysis or brain damage.
