This work compiles carefully selected training videos sent to the editorial department of an SM magazine. At the center of these recordings are two women: Yayoi, a slender and innocent-looking college student, and Maso woman K-ko, who has evolved through years of rigorous training to perfectly fulfill male desires. Yayoi has harbored a deep fascination with SM since childhood, and after meeting man A upon entering university, entered into a slave contract, continuing to undergo training to this day. K-ko, on the other hand, has been strictly disciplined for over a decade since her days as a university student, now fully devoted to satisfying men in every way possible. This video documents their experiences with forced lesbian acts, abandonment punishment, orgiastic foursomes, and prolonged anal dildo penetration, vividly portraying how their masochistic natures are cultivated through pain and humiliation. The contrasting paths each woman takes hold a compelling fascination for viewers. This is an amateur production, filmed by real-life SM enthusiasts, without the staged performances or narrative elements typical of commercial adult videos, capturing raw and intensely erotic scenes in an authentic, unfiltered manner.
