Step-Sister-Wife

A wife's husband's "other woman" known to the wife; whether openly acknowledged or not.

The legal wife of a woman's, generally a mistress, long-term boyfriend/lover/mate.

Two or more women who share a romantic relationship with one man, but do not share a dwelling/residence.

After spending 25 years with me and simultaneously spending 18 years with her, she was more like a step-sister-wife than my husband's mistress.

Since Warren Buffett never divorced his wife Susie, she and his long-term partner, Astrid, are, for all intents and purposes, step-sister-wives.

Night Shift Sisters

As referenced in the Siouxsie and the Banshees song, "Night Shift," "Night Shift Sisters" are prostitutes, as they are known for working at night, and are, for the most part, females who have built a sense of camaraderie, or sisterhood.

My Night Shift Sisters
Await your nightly visitor
They don't bother me
No they don't bother me

My Night Shift Sisters
With your nightly visitor
A new vocation in life
My love with a knife

"Night Shift" ~ Siouxsie and the Banshees
