Yes sadly Newport has really took a hit over these last 5 to 10 years. Kittens Kelly's Kandi Girls Twice as Nice and the poorly run and down right despicable Studio 1. The variety was always there in these house brothels too ranging from Black, Thai Chinese Polish, and always a Ton of girls from Bristol.
A lot of this action moved to Merthyr but that was only temporary but the Bay area is probably now the epicentre of punting around Cardiff & Newport.

, what was the name of the place at the top of town by the market, SJ was there one night, that place had the most undiscreet entrance I've ever visited.
