I have not seen her but I've been curious.
Search PERB and you will see conflicting opinions about whether or not she makes extras available.
Some said she's strictly legit, while others say they got a hand job. Perhaps it's YMMV.
Why not give her a try and report back?
I've seen her for about three years now, maybe four, averaging once every three months. I like mer massage style but never been offered any extras. No towel when faced down, and covered jr when on my back. Definitely not a clock watcher.
