A forbidden training record depicting 'Mei Kurose' and 'Yuma Koda' completely transforming into perfect sexual submissive servants. The target, walking alone in darkness, is captured and subjected to complete bodily domination. Deprived of basic human treatment, their freedom is stripped away and meals are reduced to the bare minimum. Any resistance is immediately suppressed by force, while their bodies are relentlessly manipulated for pleasure. Through repeated training, their screams of pain gradually turn into cries of ecstasy, and they begin voluntarily craving and servicing the master's cock. Falling completely into depraved sexual servitude, they abandon all reason and transform into beings driven solely by the pursuit of pleasure.
