Japanese have a huge fascination with schoolgirls; this is no secret. So releasing a porn with tied up schoolgirls is a default to the Nippon smut industry, minus the scat, piss and branding.
What this offers instead is a heavy exercise in rape scenarios starring Moe Ohsawa, Konomi Adachi,Mami Yamashita and Chiaki Endou as hapless schoolgirls that get violated by 3 guys in their classrooms and... a basement?
Lots of bondage, moaning and 14 year old screaming that will send your brain back to the good ol' days of raping girls in the Kindergarten playground.
