I have had many experiences of WS, it is one of my favourite subjects. It seems that is easily ridiculed on this forum, all the obvious innuendo jokes abound. However, my advice to you is simply look at those profiles carefully, you will see in the right hand column of Adultwork that Water Sports is either provided or not provided, (giving, receiving or both). On first contact, you could simply ask, no harm in that. You may find that the charge will increase, and you will need to give time for the woman to have a full bladder. Some women offer this in parlours, and again, you have to request it, she can simply say yes or no. However most of my experiences have been with independents. Incidentally, you may come across something called 'Hard-Sports', usually very rare, and unless you are into 'scat', one to avoid!
