Depending on how much makeup the girl uses on her face, wash your face on that last wash up. After finishing a soapland session, the next time I went to the bathroom at the nearest station afterwards, I looked into a mirror and noticed residual makeup on my face from all the kissing. From a distance you couldn’t see it, but up close it was obviously there. Especially since her makeup was a different color than my own complexion. And even if you wash your face during that last washing, check yourself in a mirror outside of the shop. Just in case you forgot she gave you a hug or a kiss before you left.
Watch you time, if at the end of a session you don’t have much time for clean up and you’re just getting the quickie shower to wash off just the main parts (junior, hands, butt), don’t forget to quickly get your face, neck, and chest too. On top of the makeup transfer situation, depending on what kinds of scents a girl may use in their hair, smell may linger on you.
Don’t let her spray you with anything. One hot summer I was sprayed with cooling spray under my shirt before I left. She asked first of course but in the moment you may think sure, lemme try that. And afterwards you have to go and buy the spray at the store since now you’re coming back smelling like something you don’t normally use or not smelling how you normally do.
Watch out for messy bed hair. Especially if you are on your back long time. Also, don’t wash your hair there unless you know it will return the same look as you did pre-session.
Throw away that conbini receipt if you stopped at a conbini in the area.
Turn off tracking on your phone and be sure you don’t have shared trackable items on you.
A little less critical but obvious and did happen to me, be sure the umbrella you get back is yours and not someone else’s one. On leaving the shop, instead of the normal long size clear conbini umbrella, I got a shorter clear one back when leaving. Only realized when I got out of the shuttle car back at the station. Easily explainable as ‘I grabbed someone else’s umbrella by mistake,’ but still, just be aware in case she asks why your umbrella is different from the one you left with.
