Autoerotic Asphyxia via Deepthroating ?

[Sub-Cocksucker]

Having a cock down my throat has always drove me crazy, and when a dom man holds me down on his cock so I cant breathe is even more intense.

Recently I sucked off a very dom older man, he had my hands cuffed behind my back and kept holding be on his cock balls deep, longer and longer each time.
To the point I eventually passed out. Woke up to him slapping me in the face with his cock, and cumming seconds later.
After I had sucked his cock clean I noticed that I had came all over the floor.

Anyone else into this? Or know anywhere there is some porn like this?
I can find lots of choking stuff, but I specifically want it down my deepthroating.

I was lucky enough to have a friend who was very Dom who taught me to deep throat by having me lay on my back on the bed with my head over the side and he would fuck my throat.  He got off on holding his cock in place balls deep, and I loved the feeling of domination. Thanks to my obsession of being a runner, I am able to hold my breath for over three minutes, and would use that time to work his cock until he shot down my throat. He never got me to pass out, but he did inspire me to up my game. To this day I have to thank him every time I give an underwater blowjob!
