One WG, in Soho London a Thai walk 'em place asked me for food. She was pretty hungry so I went downstairs to get her Chinese meal. I was a regular 'customer' for a long time.
She was pretty good, always cum in mouth. A rarity in Soho. Sadly she has gone back home to get married. Hopefully she will return as a married WG.
No, apart from this one I would as we are paying a lot of money for a service. Just be nice to them and like anything in life do not expect anything in return.
