She should have asked questions when she applied for the job as a firefighter and was told that the pay was “salary plus tips”, but thinking was never her strong suit.
Of course she wasn’t remotely strong enough to carry firefighting gear, but that was okay, because her real job was to sit in the back of the appliance half-dressed so the real firemen could use her to relieve their stress during the long shifts waiting for a call-out.
It would really have been more accurate to describe her job as “cum-dumpster” but that didn’t look as good on the station budget. She objected at first, but after the fifth time her complaints had been stifled by a stiff cock stuffed into her mouth, she accepted what was happening to her and focused on sucking.
And of course, she got to keep her tips.
