BB does happen even though the lady concerned does not offer this as a 'service'. Believe it or not a WG and a client CAN have good, amorous, sexy feelings towards each other, and in time that can lead to a BB situation. It has happened to me, recently, and a few times. I do not regret it. It enabled me to reach a climax which is rare. The lady and I have developed quite a close relationship, rather more than friendship. OK, feel free to call me a 'fluffy' but at my age (over 70) and her age (early 40s) we both know what we are doing.
She is the establishment owner and not normally a working member of the staff - but I know that at times she does have to work. It took me a couple of months of dedicated persuasion to get her knickers off. Yes, of course we have both been "checked out". We went together to the clinic.
I will also add that in my experience over many years and many parts of the world good working girls, especially those of an Oriental background, take extreme care about their personal hygiene and sexual safety. Bless them all. a Few of my worst experiences ie when lack of care was fairly obvious, have been with UK ladies.
