Last year I had my first session with a girl in a shop I often visit. I sometimes take my own massage oil because i don't like the petroleum based oil in the shop, and asked her to use it.

I accidentally left it behind after the session, but didn't worry too much when I noticed it.. It was about 6 months later before I saw her again. She was just about to start, but suddenly excused herself and dashed out of the room. She came back holding the bottle, and reminded me what it was. I've become more of a regular with her since, she still keeps the oil in her locker for me.
