Hira sneezed, letting out a jet of phlegm

Hi

Could you please tell me if the underlined part is fully natural? It's my sentence.

Hira sneezed, letting out a jet of phlegm that landed on the book her boss had been holding.

Thanks,

Tom

I don't know what you mean by "fully natural". It's grammatically correct and it's certainly evocative! I'm not sure that "letting" is quite strong enough for the image. You could use "forcing out" or "ejecting" instead.
With regard to my annotation to the verb after "her boss", it depends whether the boss was still holding the book when the phlegm landed on it. If so, use "was". If they'd been holding it shortly beforehand but it was no longer in their hand, use "had been".

"Letting out" is too mild for the image. Try something like 'blowing', 'flinging' or 'shooting'.
