Oh lol
I know 2 mls that got booking marathon with a punter and his friends, as they told me the story in 2 different occasion in 2 different shop. As now they worked in 2 different places.
They used to work in 1 shop and able to do double with them.
So the story was every week or two, they got booking from a group which all the member of the group friends each other for the whole day. So like friend A 3 hours friend B 2 hours friend C 3 hours etc etc.
And in once in a month there is a punter that always booked them for 6 hours for bj only. And I can say those 2 girl's bj is one of the best in the business. Vacuum cleaner lol.
