Seventh installment! The lovely, slender schoolgirl Yuri Kosaka is kidnapped and imprisoned. Men sniff her body odor, grope her, lick her, gradually transforming her into a depraved slut. Her cervix is penetrated directly while vibrator stimulation drives her to orgasm repeatedly. Each climax captured meticulously on CCD as she grinds her hips willingly, craving the machine. The motor continues high-speed thrusting until burning out, drenching her in thick cum as her screams of ecstasy pierce the silence!
