Throat desperately spasming around cock in a final attempt to get air in, any air at all. Fingernails getting stained with warm red from clawing at thighs and hips.
I used to chew on the wooden tables in the psych ward when I was in my teens, so I could pull huge sharp bits from it, then stab my wrists and palms with it. Probably why I have nerve damage, and fucked up teeth. LOL.
