Two dominating mistresses acquire a fresh slave, eager to mold him to their exacting standards. They subject him to harsh treatment, yet show moments of mercy by introducing him to new sensations, such as food crushed beneath their exquisite feet. The slave learns quickly and is rewarded with a face covered in hot urine, eagerly accepted into his mouth. His training progresses, leading to an even more intimate reward – receiving fresh feces from one of his new masters. In gratitude, they leave marks on his body, biting and smothering him. By the end of his ruthless introduction, the slave is fully broken in, treated as a piece of human livestock, much like a trained horse.
