This special production compiles videos sent to an SM magazine editorial department. It features two women: Yayoi, a slender, beautiful, and innocent college student, and Kako, a long-term masochistic woman who has undergone years of training. Yayoi, driven by a deep interest in SM and masochism since childhood, entered into a slave contract with Man A before college and has been under strict discipline ever since. Later, at Man A's request, she was also trained by Man T, a friend of Man A's, solidifying her role as an anal rental beast. Kako, on the other hand, has been trained by Man T since her college days and has lived as a slave for 16 years, fully embodying the life of a broken, obedient animal.
According to Man A, he asked Man T to train Yayoi with the help of Kako. Kako, from her own animal shed, handmade lewd underwear as a gift for Yayoi. These panties feature a cut-out crotch replaced with transparent film, designed so that lubrication cannot be absorbed and instead clings visibly to her pussy, creating an intensely erotic effect. Styled after children's underwear, they lack feminine elegance, instead emphasizing awkwardness and humiliation. Yet, hoping to make them slightly cuter, Kako added appliqués with names, and engraved the words "depraved" and "beast" on the buttocks.
Despite receiving no direct orders from Man T, Kako possesses an intense masochistic drive, creating tools specifically for her own degradation. By teaching Yayoi these practices, she helps deepen Yayoi's own masochistic nature. The footage of Yayoi wearing Kako's handmade underwear is intensely erotic and a must-see.
This work includes masochistic acts such as SM partner swapping, masturbation using handmade underwear, spread-leg lesbian cunnilingus, simultaneous three-hole stimulation, and forced lesbian training. Filmed by amateur SM enthusiasts, it contains raw, unfiltered scenes without typical AV staging or narrative, offering pure, explicit indulgence in depraved imagery.
