Yes, Ma'am, edited by Rachel Kramer Bussel

Erotic Stories of Male Submission 

From the back cover:

"What makes a man cower before a powerful woman? Turning the tables on rigid gender roles, the stories in Yes Ma'am detail the adventures of men who revel in submission to stern mistresses who recognize their deepest desires.  Whether bound and punished, ordered into a threesome, or put on full, naked display, these men receive the treatment they truly crave.  With stories by Stephen Elliot, Alison Tyler, Dominic Santi, and many more, Yes Ma'am shows that pleasure's best when dispensed by a firm female hand."
