This is an interesting question but I would have to say the provider came first IMHO. Just imagine a woman flaunting her assets in need of something (food,money, jewels, etc) The man cant resist anymore so he gives her whatever she wants to get what she has. Could have been the other way around I suppose. Damn I still just dont know lol!

I say the caveman made the offer

I vote for the caveman making the offer first!  My reasoning is that anthropologists have found that in many tribal communities before they were affected by religions of the Middle East (Christianity, Islam and Judaism) it was women who took on many husbands in some case.  This was done out of a need to retain land among kin groups so she often married several brothers and cousins (How is that for a bit of kink? High five as they both poke her).  We just had this discussion in one of my classes and this is still practiced in areas of Tibet, Nepal and some places in Africa and South America.  Men would often leave so who would be left to hunt and protect the woman and children if she didn't have several men she was "married" to (beginning to snicker).

Perhaps as time went on one of these women got the idea that if she added more women to her "work load" then everyone benefits...the beginnings of a brothel.

Meh...who knows!

It is likely client came, but while she may have faked it, the provider probably didn't come at all.

That is right, our primate ancestors have been doing this long before we have!

I'll personally say they came at the same time (which is how I prefer to cum as well )
