^^^^. I can kind of see the point your making. At AMPs the girls go to work knowing they’re going to fuck a dozen guys, so they douch between clients, where as sub amp girls more than likely go to work thinking at most they’ll give a handjob to a few guys, so when the one off guy comes in that they actually fuck, they’re not as prepared as the FS girls are, so you could wind up with the odor you’d get from any woman that’s been on her feet doing a physical job all day long.
I mean, can you imagine going down on a female postal worker In August, at the end of her 15+ mile shift before she showers? Probably not a good idea.
