dangers of chem

I recently got to know a guy K, a gorgeous guys in his late 30s but look like in his mid 20s. He have a fit body with a nice built chest and well developed abs. I was attracted by him. We chatted and flirted with each other and soon we end up in bed and also soon enough I found out that he is not that ‘perfect’ at all - he is into chem.
Despite that I was still clouded by his sexiness and we had sex on Friday and Saturday none stop and I was surprise I was able to keep up with him. Having sex with a guy who is under the influence of ‘ice’ and perpetually inhaling ‘poppers’ was way out of the world. The way he response to my touches and were as though my fingers can emit low electric current and all I know that his body shudders a lot and the moaning was very stimulating. All I know that he kept commenting on how good I am and kept on calling out my name.
It got me really horny at a point and I decided to try something I wanted to do long time ago. I tied him up against the wall blindfolded. I teased him for a good 30 minutes and I can see he is at the edge of his senses where he began to ask me to fuck him which I didn’t until I know he can’t stand it any longer. We went into all sorts of position we could think of and while he was on top of me, he kept on moaning and gasping for air- he cummed without realising it.
How do I rate this sex experience? 10 out of 10 of course.
On Monday I called him and I can hear that he is not doing well, he told me he lost his job and failed his interview which he told me that he would have aced it without any problem. He can’t think and can’t remember stuff any more and all he could think of is having another dose of ‘ice’ every single hour. He said he was addicted and he know he is heading deeper and deeper into the abyss. He made a decision that no one can help him but himself that he threw all his drugs away. I was reminded by him again and again that never be curious to try such thing or else I will end up like him in a pleading voice. I had a feeling that he is close to tears already and my heart broke into a million pieces as I was listening to this conversation.
What I couldn’t understand is that why a person like him - good looking, sexy, perfectly chiselled body, have a job and car but got stuck in the grasp of what seem harmless at first but in the end a disaster - chem or what all of know fondly, drugs.
I wish you all the best in stopping this habit K!
