Mistress RISA strictly trains and raises three masochistic pig slaves. She makes them compete against each other, ranking them first, second, and third, progressively increasing the type and severity of discipline based on their position. As a result, the slaves desperately struggle and strive to become number one. Mistress RISA enjoys watching their efforts, toying with them while alternating rewards, denial, and breaking sessions, molding them into exemplary slaves. Their semen is collected as breeding stock for mating with female pigs.
