In a dungeon lit only by dim, flickering candles, a bi slave is presented to two mistresses for training. They begin by humiliating him, making him crawl and beg for their touch. One mistress takes control, using a whip to tease and taunt the slave, while the other fingers his ass, preparing him for what's to come. The slave is then bent over, and the mistresses take turns fucking him with a strap-on, their moans filling the room as they enjoy their power over him.
