The positions in bondage are designed for several reasons; immobilize, restrain, to inflict more suffering, etc. Today the bondage is used in most of these ways, to make her suffer in a grueling back bending suspension, to restrain her in the first scene to allow me to torment her more, totally immobilizing her with her face down and her ass up, and finally all at once she is fucked in the final scene with a brutal crotch rope and uncontrollable orgasms.
