Modern

Modern refers to our day to day life, except in scenarios that are less hair raising and more lewd. While this doesn't seem all to exciting, it puts the reader in a more much conventional and more recognizable, therefore, making the scenario easier to write in and the reader -both you and the character- to fully understand how the world in the book works.

Suggestions are:

A secretary sucking her boss off to get a promotion.

A waitress getting an extra tip if she sucks off the canolli cream of a customer's meal.

A student being sent to the principal's office and gets some disciplinary action.
