What's on your mug?

A woman who enjoys having control over a guy ( who might have a gf or wife) and dominating him. Domination could include humiliation and physical discipline or it could be based on positive feedback. It is also usually assumed that the men should submit all of his paycheques to his mistress and she will decide if he can have a part of it for himself or his wife

Mistress: good boy now send me all of your paycheque. Man: can I have some to pay for my wife birthday Mistress: Okay You can have 5$ for yourself. Send the rest now and I will let you touch me

A guy has to have a girl already to have a mistress, simple.

A guy has to have 2 girls in his life to have a mistress. He has to have a girl, and he has to have a girl on the side. A guy who does not have any girls in his life has no mistress, simple.

A girl on the side, usually a married guys girl on the side.

Having a girl on the side means a guy has 2 girls. A guy who has none has no mistress.
