Huh... HUM !
Personally i always take my shower right before she arrive. I ask the booker to keep my in touch if she is gonna be late or not and such thing because i want her to arrive not more than 15 MINUTES after i get out of the shower. I am really picky on this...
I expect my SPs to also be super clean when they start it up with me. I apreciate when a SP excuse herself to the bathroom for 5 mins before we start, i know she make sure she is super clean and all. I don't mind if im the first client that she wash before going to my place... She get drive anyway, so not like she is gonna get sweaty or whatever. And the shower at the end is also something i apreciate to see, cause yeah its not gonna affect me on the spot, but i want the next customer to ... well... not lick my jizz off her body... lol
No seriously being clean on both side is something that should be expected and should be done.
