I went in expecting it to go in a "beauty salon + sex service" direction, so it seemed a bit unprofessional when she started peeping and masturbating by herself. But then it turned out that it wasn't part of the service at all and she was just using her business to prey on women, so...
She said she'd put something in the tea to "make her more sensitive", but it must've been some pretty strong stuff if the poor girl was so out of it that she couldn't tell the difference between fingers and boobs. No wonder she thought it was a dream afterwards.
