In the first of a two-part series, KinkyMasoSlut, a self-proclaimed slave to kink, pushes her boundaries with a brutal CBT session. She starts with nipple clamps and ball stretcher, her body adorned in lingerie and stockings. A urethral sound is inserted, stretching her sensitive urethra, as she controls the e-stim device with a remote. She then moves on to CBT, tugging at her stretched sack, before nipple stretching, leaving her a sweaty, trembling mess, eager for more.
