>>I wanted the reader insert to die looking and feeling like a naughty little slut, and literally choking on a penis seemed perfect symbolism.

I would take that from the other direction because was kind of determination the man must have to keep his cock inside for that long without moving it?
maybe it could be plausible if he was some kind of monster with 10-inch cock which he can pound inside of your throat while still keeping it inserted al the time

in that case, it is totally plausible if we somehow assume that he will manage to stick it deep in the throat and pound it for few minutes ignoring her panicking and kicking trying to free herself
