Sunstone is “sensible” BDSM , we follow two women who are into bondage, and the bunch of people around them. They are “human” persons, not caricatural or oversimplified for cartoon reasons. They have weaknesses, strengths, aspirations, it’s easy to partially identify with them, to love them, and there are several moments when I laughed. Bondage is seen “intellectually”, as a relationship of trust, where the control comes from top and bottom… that is so interesting!
