Look under Gumtree or Vivastreet for massage in West Midlands. A fair few flats crop up. I've visited about 6 and had a happy finish every time. As a rule of thumb, the more boob you can see in the pic associated with the Gumtree listing, the more likely happy finish is going to be. There's three separate operations alone in the block opposite the Mailbox! The Burmese girl (floor 6?) actually let me fuck her for what amounted to an extra tenner.
