[Twin Wives] Continuous Fainting Training Chisato Uchida

Chisato became a flesh slave for her depraved brother-in-law, taking her sister's place. The brother-in-law was cunning, secretly advancing his plans without Chisato's knowledge. Though initially against her will, Chisato repeatedly reached climax over and over again. That pleasure gradually seeped into her heart, until eventually she began actively seeking out forbidden ecstasy herself.
