One of the Osterley Crew of Chinese massage ladies, called Chloe, has very long nipples. If you don't need full service, I'd recommend her. I had an hour massage with her in Southfields, near Ealing. I paid £85 plus £20 for covered oral on me, but I asked her if I could 69 with her, and she was very accommodating, and I gave her oral in a couple of positions and she really went for it.
