Fiona, left alone with roommate Nicky, turns her boredom into a free-use sex fantasy. She masturbates openly, inviting Nicky to use her whenever he wants. He accepts, fucking her hard and rough, while she remains expressionless, exactly as she's imagined in her taboo daydreams. They engage in conversation mid-coitus, Fiona's voice cool and detached, her body the willing, free-use vessel for Nicky's desires.
