The episode, titled "It's Good to Be Kink," will see Olivia (Kerry Washington) spring to action when she learns of a woman — judging from the photos below, played by Dunham — who plans to expose the sex secrets of some of D.C.'s most elite.

The guest role marks Dunham's latest tie-in to the world of Scandal. The actress and Girls creator recently hired Scandal inspiration Judy Smith as strategic council.
