[HUNT-347] A group of innocent plays who admire delinquents end up at a playground where they don't belong, and are played to test their courage by seeing how naughty they can get with the old men who are extorted by their seniors. (Censored)

These curious innocent girls came to a yankee hangout purely out of admiration, but they're so innocent that they're completely ignored... Desperate to somehow gain the approval of the senior yankees, these innocent girls prove their mettle by engaging in naughty tests of courage (upskirts, fellatio, stripping off their uniforms and bloomers and having sex) with the salaryman-style men who are being mugged on the spot!
