Blowjob bet becomes [m]ore [f]un with older coworker

I worked at a pharmacy while in college because where else could I make $15/hour part time with paid benefits. I was the youngest employee and 1 of 3 guys who worked there. Most of the staff were friendly and sarcastic but married or otherwise not interested in anything more than counting pills & billing insurances. Susan was similar but every now and then would flirt when it was just a few of us working and usually when the pharmacist wasn’t around. She was also 36, married with 2 kids, tan skin, a healthy rack and some great curves for a 5’4” brunette.

I joked along most of the time and didn’t think anything of it until 1 day about 18 months in to the job we were working on a prescription and the insurance billing wasn’t processing correctly. Complex request for a customer and after we’ve prepared the medicine we can’t get the system to process it through the insurance. Pharmacist works at it to no avail. Susan, the resident insurance billing expert, can’t figure it out. It’s becoming an ordeal and the customer is waiting to get their medicine and be on their way. I offer to take a crack at it despite previously unsuccessful attempts by more veteran staff. As I’m working my way through insurance screens Susan’s soft sultry voice whispers in my ear, “I’ll bet you a blow job it won’t work.” While I heard her clearly I also thought…haha. Ok. But that’s an empty wager.
Click, click, type, type, change a few codes & voila insurance accepts the prescription, spits out a copay for the patient & all this with Susan hovering over my shoulder waiting for resolution.
