Two insatiable sluts, bound and gagged, are presented to a dominant mistress. She teases them with a riding crop, leaving red welts on their skin. One by one, she forces their heads down, impaling their mouths on a massive strap-on, making them gag and choke on its length. As they struggle to breathe, she laughs, enjoying their torment, before switching places to fuck them senseless in their tight, wet pussies.
