This is a night school... Underclassmen boys brought here by their seniors. There are female students who are restrained there. Their eyes are vacant, and their expressions seem resigned. Under the seniors' instructions, the underclassmen boys start to touch the female students' bodies as if appraising them, and the girls barely resist. The seniors are filming this scene with a video camera. This bizarre situation only excites the underclassmen boys more, and they gradually escalate from kissing, hand jobs, cunnilingus, to fellatio, while the female students remain passive, eventually being gang-raped...
