Incestuous acts while talking to boyfriends on the phone, entertaining the brother's clients, lending sisters out to friends, cleaning the house without underwear—his control manifests in various ways. The sisters signal with their eyes, saying "I'm embarrassed" or "I can't do this," but the brother ignores them completely. Gradually, the sisters begin to discover pleasure within the humiliation, and eventually choose to accept everything, seeking the brother's love.
