10 years ago, seeking a change from the local deadbeats on AW I booked with an Agency for an outcall, choosing a girl from her photos. An entirely different girl with an entirely different name appeared - bit of a novice, but I had a really good time with her and we got on well. She told me that the Agency (one man effort) took 33% of her earnings but wasn`t giving her enough work to live on, while the boss was also pestering to fuck her for free. I helped her to get free of him, saw her frequently, and she became my regular for several years.
As far as I`m concerned the Agency Boss is simply the English equivalent of Sergei, and committing a crime while the girl who works for him is not.
