Lucy, just curious, are you getting these requests in the UK or in Ireland? If you are getting them in Ireland, please contact me as there are a few TW who are around the Dublin area, who always call up the new girls and ask for the most extreme things. One in particular wants you to tie a plastic bag over his head. A complete a total utter waste of space and time.
But on another note, serious Dom clients will not contact a novice in the scene for extreme services. They know better, and usually will want a professional experienced lady who knows what she is doing. Usually what you get is some poor fool who has seen a few you-porn videos and are turned on by the idea of a certain services, and decides this is the life for him, only to discover that being tied up, gagged and hung upside down like a side of beef and whipped to within an inch of his life is both traumatizing and painful. This happens ALOT in Ireland.
