One I was quite regular with had OH that worked off shore so tended to be available/unavailable to match his work pattern, saw her once while he was at home but she had booked a cheap hotel & had a hen night to go on to to cover her tracks. Her mother & sister both knew she was on the game and helped cover for her. Retired now unfortunately.
A Polish girl had husband & kids back in Poland - she was quite frank about it, said he was a great dad but neither he nor she could earn what she earned as an 'office administrator' here so thats what she did - administered my dick quite well
Of the current girls one definitely knows but I am pretty sure he doesn't 'pimp' her, just ignores it for the benefit of the money, I actually know where he works so he isn't relying on her for income.
The others I see I am pretty sure are single.
