Imagine my surprise!!
There is a massage place in our area, it is out of town and under the County jurisdiction.
The place is very well known for doing happy endings, it's like a secret everyone knows about.
I go there myself, get hand jobs, blow jobs, and a rare fuck since for that they want $100 extra.
The receptionist is the owner, she is about 60, she sends the client down to shower, then into one of the 6 rooms.
Busy place, and we get whoever is the next gal available, we don't get to choose.
I was lying there on my tummy, towel over my ass when the woman walks in, she gasps. I look over, it's my 24 year old sister, she is married and supposed to be working in an office.
She started to leave but I said, "Relax, Sandy, I won't tell anyone."
She hesitated, then said, "Oh well, what the fuck!"
That was neat, I thought about what if with my Sister for some time, finally got a nice hand job from her, only cost me $75.
I did ask her what she would do for the $100 tip, she told me "In your dreams, asshole!" laughed and left.
But? Who knows??
