Nanatsu, the seven deadly sins, come to life in this intense joi scene. Merlín is bound and helpless, at the mercy of his mistress who uses her knowledge of the human body to push him to his limits. The room is dark, the air thick with the scent of sweat and the sounds of their ragged breaths. As she whispers the seven sins in Spanish, he succumbs to each one, his body wracked with pleasure and pain, in this ultimate test of his submission.
