The racy, come-hither title of Mark O’Halloran’s 70-minute work disguises a fascinating drama en déshabillé that explores the loneliness that underlies anonymous sexual encounters and a desire by participants to connect more fully than only with sex. Though the conversations follow intercourse, they reveal more about the characters’ lives up to that point than what happens afterward. Staged with simplicity and power by Tom Creed, O’Halloran’s play is thought-provoking, sad, and thoroughly engaging.
