Liz makes a mental note of that, then almost bursts out laughing.  'Note to self... don't give a guy a blow job right after he raises an army of undead'... yeah, that'll come in handy quite often.  But along with that laugh comes some deep throat spams.  That brings an idea to her mind.  Easing him deeper into her mouth, she lets his member fill her throat, then starts to swallow against it.  Maybe that will help him find his mood!
