In September last year I was in the Tonbridge area and called a few places advertising on Gumtree. I ended up going to a residential flat in Tunbridge Wells for a one hour massage for £80. The Chinese milf was quite sexy, and the massage session turned into something more like a nice GFE: lots of DFK, OWO, sex. Paid an extra £20 and left quite a happy man.
I didn’t bother with a review, it was one of those places where the girls move regularly. I just looked on Gumtree and there’s no ad for the place I visited in Tunbridge Wells. Appreciate that the OP was asking about Tonbridge but they are not far apart.
