A notorious director presents a perverted masterpiece! Kai Miharu undergoes a memory-erasure program, gradually losing her past. Shocked by secrets revealed by fellow prisoners, she can't hide her horrified expression. The facility's dark truth? Each year, select inmates are trained as covert executioners, secretly eliminating criminals who've slipped through the justice system. But those deemed untalented or who defy the guards are instantly executed under this terrifying system. The next morning, guards line up the prisoners, sniffing their vaginas and anal holes to check for hidden items. When the warden announces, "Today's training has been abruptly changed to the torture chamber," the line breaks into chaos, fear spreading across their faces. Then, preparations begin to execute one prisoner. After performing incense rituals, the guard thrusts three fingers into her anus, twisting and churning roughly. Next, a vibrator delivers humiliating anal stimulation, causing her to involuntarily piss and climax repeatedly in a pitiful state. Witnessing this execution intensifies the prisoners' terror. Still, the guards hand out lewd toys, forcing them into a brutal game of survival through relentless sexual torment. (Provided by Dream Room: M-Deshi)
